The aim of this study was to assess the impact of adequate treatment of concomitant diseases in the elderly undergoing Vestibular Rehabilitation (VR). METHOD: 52 elderly patients with complaints of vertigo and/or imbalance requiring VR participated in this prospective study. The trial was designed as an open clinical assay at the Ear Nose and Throat Department Geriatric Otoneurology Clinic, and was done between 2003 and 2005. Patients were compared with the total group of elderly individuals treated with VR during the same period. RESULTS: 65 diseases were diagnosed in the study group, an average 1.25 diseases per patient. After the treatment of these diseases, patients underwent VR. The effectiveness of VR (remission and partial improvement rates) was 84.5% in the study group against 81.8% in the control group, which was not significant. Remission of symptoms, however, was present in 69.2% of the study group against 43.18% of the control group, which was statistically significant. CONCLUSION:The difference in the effectiveness of VR in both groups highlights the importance of the etiological treatment of concomitant diseases in patients with vestibular disorders.

Cerumen is a naturally occurring, normally extruded product of the external auditory canal. It is usually asymptomatic, but when it becomes impacted it can cause complications such as hearing loss, pain, or dizziness. It also can interfere with examination of the tympanic membrane. Depending on available equipment, physician skill, and patient circumstances, treatment options for cerumen impaction include watchful waiting, manual removal, the use of ceruminolytic agents, and irrigation with or without ceruminolytic pretreatment. The overall quality of the evidence on treatment is limited. Referral to an otolaryngologist for further evaluation is indicated if treatment with a ceruminolytic agent followed by irrigation is ineffective, if manual removal is not possible, if the patient develops severe pain or has vertigo during irrigation, or if hearing loss is still present after cerumen has been removed. The use of cotton swabs and ear candles should be avoided.

Total resection of a hemorrhagic tectal pilocytic astrocytoma--case report.
Neurol Med Chir (Tokyo). 2007 May;47(5):219-21
Authors: Oka F, Yamashita Y, Kumabe T, Tominaga T
A 21-year-old man presented with a hemorrhagic pilocytic astrocytoma of the tectal plate manifesting as sudden onset of severe headache, vertigo, nausea, and vomiting. Computed tomography demonstrated acute hydrocephalus and hemorrhage within the brain stem and fourth ventricle. Magnetic resonance (MR) imaging revealed a dorsally exophytic tectal tumor as hypointense on the T(1)-weighted image and hyperintense on the T(2)-weighted image with contrast enhancement. Radical resection of the tumor was selected because of the unusual aggressive clinical course with hemorrhage and suspicion of malignant components. The tumor was totally resected via an occipital transtentorial approach using a neuronavigation system without surgical complications. The histological diagnosis was pilocytic astrocytoma. The patient was discharged home without neurological deficits on the 9th postoperative day. Twenty-three months after the surgery, follow-up MR imaging demonstrated no recurrence. Tectal plate pilocytic astrocytoma is rarely associated with hemorrhage but should be considered in the differential diagnosis of intracranial hemorrhage with acute presentation. Such exceptional tectal tumors should be resected radically and undergo histological examination to decide on further appropriate treatment.

Medullary hemorrhagic infarction after radiation for nasopharyngeal carcinoma.
Intern Med. 2007;46(9):611-5
Authors: Liu JR, Huang J, Zhang M, Wei QC, Song Y, Huang JZ, Ding MP, Jia PJ
Head and neck irradiation may lead to accelerated atherosclerosis over several years. Delayed stroke has been described after head and neck irradiation administered for a number of conditions. However, brain stem stroke has only rarely been associated with irradiation. We report a patient with medullary hemorrhagic infarction 6 years after radiotherapy for nasopharyngeal carcinoma. A 42-year-old normotensive Chinese male had rapid onset of vertigo, diplopia, ataxia, dysphagia, hypophonic dysarthria, hemiparesis, and respiratory distress. Cranial MR imaging 2 days after symptom onset showed medullary infarction, and cranial MR imaging 5 days after symptom onset showed medullary hemorrhage. He needed ventilatory support and died of bacterial pneumonia 1 month later. Other risk factors for stroke were absent. Hemorrhagic infarction in this patient was likely associated with the radiotherapy. Radiotherapy is the first choice of treatment for nasopharyngeal carcinoma, however, it may induce fatal medullary hemorrhagic infarction.

Toll-like receptor 2-dependent NF-kappaB activation is involved in nontypeable Haemophilus influenzae-induced monocyte chemotactic protein 1 up-regulation in the spiral ligament fibrocytes of the inner ear.
Infect Immun. 2007 Jul;75(7):3361-72
Authors: Moon SK, Woo JI, Lee HY, Park R, Shimada J, Pan H, Gellibolian R, Lim DJ
Inner ear dysfunction secondary to chronic otitis media (OM), including high-frequency sensorineural hearing loss or vertigo, is not uncommon. Although chronic middle ear inflammation is believed to cause inner ear dysfunction by entry of OM pathogen components or cytokines from the middle ear into the inner ear, the underlying mechanisms are not well understood. Previously, we demonstrated that the spiral ligament fibrocyte (SLF) cell line up-regulates monocyte chemotactic protein 1 (MCP-1) expression after treatment with nontypeable Haemophilus influenzae (NTHI), one of the most common OM pathogens. We hypothesized that the SLF-derived MCP-1 plays a role in inner ear inflammation secondary to OM that is responsible for hearing loss and dizziness. The purpose of this study was to investigate the signaling pathway involved in NTHI-induced MCP-1 up-regulation in SLFs. Here we show for the first time that NTHI induces MCP-1 up-regulation in the SLFs via Toll-like receptor 2 (TLR2)-dependent activation of NF-kappaB. TLR2(-/-)- and MyD88(-/-)-derived SLFs revealed involvement of TLR2 and MyD88 in NTHI-induced MCP-1 up-regulation. Studies using chemical inhibitors and dominant-negative constructs demonstrated that it is mediated by the IkappaKbeta-dependent IkappaBalpha phosphorylation and NTHI-induced NF-kappaB nuclear translocation. Furthermore, we demonstrated that the binding of NF-kappaB to the enhancer region of MCP-1 is involved in this up-regulation. In addition, we have identified a potential NF-kappaB motif that is responsive and specific to certain NTHI molecules or ligands. Further studies are necessary to reveal specific ligands of NTHI that activate host receptors. These results may provide us with new therapeutic strategies for prevention of inner ear dysfunction secondary to chronic middle ear inflammation.

Positional vertigo afterwards maxillary dental implant surgery with bone regeneration.
Med Oral Patol Oral Cir Bucal. 2007 Mar;12(2):E151-3
Authors: Rodr?guez Guti?rrez C, Rodr?guez G?mez E
Benign paroxysmal positional vertigo (BPPV) is the most common form of vertigo. It is caused by loose otoconia from the utricle which, in certain positions, displaced the cupula of the posterior semicircular canal. BPPV most often is a result of aging. It also can occur after a blow to the head. Less common causes include a prolonged positioning on the back (supine) during some surgical procedures. Additionally one can include in this ethiopathogenesis the positioning required during the maxillary dental implant surgery with bone regeneration related to a forced head positioning and inner ear trauma induced by dental turbine noise working in the maxillary bone. Two cases of patients who suffered BPPV after undergoing maxillary dental implant with bone regeneration procedures are reported. Diagnosis and treatment are also described.

Prognostic indicators of management of sudden sensorineural hearing loss in an Asian hospital.
Singapore Med J. 2007 Jan;48(1):45-9
Authors: Tiong TS
INTRODUCTION: This retrospective review evaluates the prognostic indicators in the management of sudden sensorineural hearing loss (SSNHL) in otorhinolaryngology patients admitted to Brunei RIPAS Hospital. METHODS: The review covered data collected from 1996 to 1998, and included patients who were treated with naftidrofuryl and dexamethasone. Their hearing improvement (more than 20 dB) in relation to pure tone audiogram patterns, hearing loss severity, vertigo, age of the patients and duration from symptom onset to time of treatment, were evaluated. RESULTS: After exclusion of three patients with known causes of hearing loss, 50 patients with idiopathic SSNHL were reviewed. Six audiogram patterns were observed with good prognostic indicators in patterns 1 and 4, where respectively, 95 percent and 100 percent of the patients improved. The hearing improvement was noted in the majority of the patients with mild or moderate degree of hearing loss, especially noticeable in audiogram patterns 1 and 4. Initial vertigo gave poor prognosis in hearing (more than 33 percent patients with vertigo improved versus 88 percent patients without vertigo improved). Patients aged between 21 and 60 years appear to have better prognosis of hearing improvement compared to those who are outside of this age range. 92 percent patients whose treatment started within the first week of onset of hearing loss experienced hearing improvement compared to 84 percent patients whose treatment started in the second week after onset. CONCLUSION: Fairly consistent with the previously-reported prognostic indicators are hearing loss severity, vertigo, age and duration of onset to treatment, though there was reasonably good prognosis when the patients were treated in the second week from hearing loss onset. Further findings of note were the six audiogram patterns and the good prognostic indicators in patterns 1 and 4.

Vertigo after renal transplantation: a sign of paucisymptomatic cryptococcal meningitis.
Exp Clin Transplant. 2006 Dec;4(2):525-7
Authors: Mehrenberger M, Kamar N, Borde JS, Est?ve-Fraysse MJ, Viguier A, Recco P, Durand D, Rostaing L
We report what is to our knowledge the first case of severe isolated vertigo that developed after renal transplantation and was a manifestation of cryptococcal meningitis. Treatment with antifungal therapy resulted in the complete resolution of vertiginous symptoms. Immunosuppressed patients with an opportunistic infection of the central nervous system can present with extremely tenuous features of infection and atypical neurologic signs.

OBJECTIVE: To delineate 2-year efficacy of Meniett device therapy in people with classic, unilateral, M?ni?re's disease unresponsive to traditional medical treatment. DESIGN: A 2-year long-term unblinded follow-up after a prior randomized, placebo-controlled, multicenter clinical trial of the Meniett device for M?ni?re's disease. SETTING: Follow-up was performed remotely by using diaries and questionnaires mailed to the data coordinating center by the participants. Those who failed to mail their diaries were interviewed by telephone. PARTICIPANTS: Sixty-one study participants agreed to use the Meniett device and report their symptoms for 2 years. All had active, unilateral cochleovestibular disease. Outcomes are available for 58 participants; 2 were unavailable for follow-up and 1 was excluded because of a concurrent condition that precluded Meniett device use. INTERVENTIONS: Participants were advised to adhere to a low-sodium diet, use the Meniett device 3 times daily, and maintain a patent tympanostomy tube in the affected ear. Diuretic and vestibular suppressant medications were used as needed. MAIN OUTCOME MEASURES: Outcomes were based on the participants' daily diary, questionnaires, and telephone interviews. Three different analyses were prepared: tracking of vertigo frequency throughout the study, comparison of vertigo frequency before and at the end of Meniett device use (American Academy of Otolaryngology-Head and Neck Surgery Foundation reporting guideline), and Kaplan-Meier estimates of vertigo remission and recurrence. RESULTS: Vertigo levels gradually improved for most but not all participants. American Academy of Otolaryngology-Head and Neck Surgery Foundation class A (remission) or class B (greatly improved) results occurred in 67% (39/58) of participants, and class F (dropped out to receive surgical therapy) results occurred in 24%. Of the 44 nondropout participants, 39 (89%) had American Academy of Otolaryngology-Head and Neck Surgery Foundation group A or B outcomes. People who went into remission were highly likely (80%) to remain in remission long term; participants who achieved remission (20/43; 47%) did so within the first year of follow-up. CONCLUSIONS: Use of the Meniett device was associated with a significant reduction in vertigo frequency in about two thirds of the participants, and this improvement was maintained long term. Therapy with the Meniett device is a safe and effective option for people with substantial vertigo uncontrolled by medical therapy.

The Superior Canal Dehiscence Syndrome (SCDS) was first reported by Minor at. Al. (1998), and has been characterized by vertigo and vertical-torsional eye movements related to loud sounds or stimuli that change middle ear or intracranial pressure. Hearing loss, for the most part with conductive patterns on audiometry, may be present in this syndrome. We performed a literature survey in order to to present symptoms, signs, diagnostic and therapeutic approaches to the SCDS, also aiming at stressing the great importance of including this syndrome among the tractable cause of vertigo. We should emphasize that this is a recent issue, still unknown by some specialists. The Correct SCDS diagnosis, besides enabling patient treatment, precludes misdiagnosis and inadequate therapeutic approaches.

Oral treatment with alpha-lipoic acid improves symptomatic diabetic polyneuropathy: the SYDNEY 2 trial.
Diabetes Care. 2006 Nov;29(11):2365-70
Authors: Ziegler D, Ametov A, Barinov A, Dyck PJ, Gurieva I, Low PA, Munzel U, Yakhno N, Raz I, Novosadova M, Maus J, Samigullin R
OBJECTIVE: The aim of this trial was to evaluate the effects of alpha-lipoic acid (ALA) on positive sensory symptoms and neuropathic deficits in diabetic patients with distal symmetric polyneuropathy (DSP). RESEARCH DESIGN AND METHODS: In this multicenter, randomized, double-blind, placebo-controlled trial, 181 diabetic patients in Russia and Israel received once-daily oral doses of 600 mg (n = 45) (ALA600), 1,200 mg (n = 47) (ALA1200), and 1,800 mg (ALA1800) of ALA (n = 46) or placebo (n = 43) for 5 weeks after a 1-week placebo run-in period. The primary outcome measure was the change from baseline of the Total Symptom Score (TSS), including stabbing pain, burning pain, paresthesia, and asleep numbness of the feet. Secondary end points included individual symptoms of TSS, Neuropathy Symptoms and Change (NSC) score, Neuropathy Impairment Score (NIS), and patients' global assessment of efficacy. RESULTS: Mean TSS did not differ significantly at baseline among the treatment groups and on average decreased by 4.9 points (51%) in ALA600, 4.5 (48%) in ALA1200, and 4.7 (52%) in ALA1800 compared with 2.9 points (32%) in the placebo group (all P < 0.05 vs. placebo). The corresponding response rates (>/=50% reduction in TSS) were 62, 50, 56, and 26%, respectively. Significant improvements favoring all three ALA groups were also noted for stabbing and burning pain, the NSC score, and the patients' global assessment of efficacy. The NIS was numerically reduced. Safety analysis showed a dose-dependent increase in nausea, vomiting, and vertigo. CONCLUSIONS: Oral treatment with ALA for 5 weeks improved neuropathic symptoms and deficits in patients with DSP. An oral dose of 600 mg once daily appears to provide the optimum risk-to-benefit ratio.

Radiation therapy for glomus tumors of the temporal bone.
Rev Bras Otorrinolaringol (Engl Ed). 2005 Nov-Dec;71(6):752-7
Authors: Dall'Igna C, Antunes MB, Dall'Igna DP
The treatment of glomic tumors has been controversial since its first description. It can be done with surgery, radiotherapy or just expectation. AIM: The objective of this paper was to evaluate the effectiveness and complications of radiotherapy. STUDY DESIGN: clinical with transversal cohort. MATERIAL AND METHOD: It was made a retrospective review in the charts of the patients with glomus jugulare tumors treated with radiotherapy. Disease control was determined by (1) no progression of symptoms or cranial nerve dysfunction or (2) no progression of the lesion in radiological follow-up. It was also evaluated the follow-up period and the sequelae of the treatment. RESULTS: Twelve patients were included, 8 of then women. The follow-up period was from 3 to 35 years, with a media of 11,6 years. The main symptoms were: hearing loss, pulsate tinnitus, dizziness and vertigo. The signs were pulsate retrotympanic mass, facial palsy and cofosis. The tumors were staged using Fisch's classification. The radiotherapy was performed with linear accelerator with dose ranging from 4500-5500 in 4-6 weeks. In the follow-up period were possible to identify sequelaes like dermatitis, meatal stenosis, cofosis and facial palsy. DISCUSSION: The signs and symptoms were the same found in the medical literature. The type and dosages of the radiotherapy were also the same of others reports. All patients had improvement of the symptoms and only one was not considered as having disease controlled. Complications were, in general, minor complications, with exception of the cofosis and facial palsy. CONCLUSION: Radiotherapy is a viable alternative to treatment of these tumors because their good response and low level of complications. It should be considered specially in advanced tumors where a surgical procedure could bring a high level of morbidity.

Endolymphatic sac tumour: a rare cause of recurrent vertigo.
Singapore Med J. 2006 Jul;47(7):627-30
Authors: Ong YK, Chee NW, Hwang PY, Goh J
Endolymphatic sac tumour occurring in a 32-year-old man presenting with Meniere's like symptoms of recurrent vertigo, hearing loss and tinnitus is described. Magnetic resonance imaging and computed tomography showed a vascular bone tumour centred over the retrolabyrinthine aspect of the temporal bone where the endolymphatic sac was located. Surgical excision via a translabyrinthine approach was performed. Endolymphatic sac tumours are rare papillary adenocarcinomas that arise from the endolympatic sac. It can be mistaken both on radiology and histology for other tumours such as paragangliomas, renal or papillary thyroid carcinoma metastases. Surgical excision is the treatment of choice but sacrifice of the auditory and facial nerve may be needed in advanced cases to achieve tumour clearance.

Efficacy of postural restriction in treating benign paroxysmal positional vertigo.
Arch Otolaryngol Head Neck Surg. 2006 May;132(5):501-5
Authors: Cakir BO, Ercan I, Cakir ZA, Turgut S
OBJECTIVE: To investigate the efficacy of postural restriction after canalith repositioning in treating benign paroxysmal positional vertigo (BPPV). DESIGN: Prospective trial of patients with postural restriction vs those without postural restriction after treatment. PATIENTS: Patients with classic BPPV and with BPPV without nystagmus were treated using the modified Epley canalith repositioning procedure. Patients were randomly separated into 2 groups. The first group was instructed to wear a cervical collar and to maintain an upright head position for 2 days. The second group had no motion restriction. After 5 days, the patients were followed up and evaluated using the Dix-Hallpike test. RESULTS: In the first group, 56 of 62 ears healed after the first maneuver, and the remaining ears healed after the second. In the second group, 45 of 57 ears healed after the first maneuver, 6 after the second, and 5 (with subsequent postural restriction) after the third (1 ear did not improve). Five patients in the first group and 3 patients in the second group had BPPV without nystagmus; all of these patients healed after a single maneuver. The difference between the 2 groups in the number of maneuvers required for treatment was statistically significant (P<.05). The number of patients who required a third maneuver was significantly higher in the second group (P<.05). CONCLUSIONS: Postural restriction enhances the therapeutic effect of canalith repositioning in the treatment of posterior semicircular canal BPPV. The long-term efficacy of postural restriction in preventing BPPV recurrence has not been demonstrated.

A 50 year old woman experienced an episode of vertigo and nystagmus about 10 minutes after receiving her first treatment with acupuncture for shoulder pain. The nystagmus was confirmed by several health professionals. She had no previous history of nystagmus, and the symptom was not associated with feelings of faintness. Her blood pressure was 90/50 at the onset of symptoms but returned to normal while the symptoms continued. She recovered spontaneously after about five hours. Nystagmus after acupuncture has not been unequivocally reported before, though dizziness associated with hypotension is common. In this case the association may be coincidental, or a focal neurological response to needling; if the latter, then it should be regarded as an unavoidable idiosyncratic reaction.

BACKGROUND: Benign paroxysmal positional vertigo of the posterior canal (PC-BPPV) is a common vestibular disorder and can be easily treated with Epley's manoeuvre. Thus far, the short-term efficacy of Epley's manoeuvre for treatment of PC-BPPV is unknown. OBJECTIVES: To evaluate the efficacy of Epley's manoeuvre for treatment of PC-BPPV 24 h after applying the manoeuvre. METHODS: The short-term efficacy of Epley's manoeuvre was compared with a sham procedure in 66 patients with PC-BPPV by using a double-blind randomised study design. RESULTS: 24 h after treatment, 28 of 35 (80%) patients in the Epley's manoeuvre group had neither vertigo nor nystagmus on positional testing compared with 3 of 31 (10%) patients in the sham group (p<0.001). CONCLUSION: Epley's manoeuvre is shown to resolve PC-BPPV both effectively and rapidly.

Cutaneous burns treated with hydrogel (Burnshield) and a semipermeable adhesive film.
Arch Surg. 2006 Jan;141(1):39-42
Authors: Osti E
HYPOTHESIS: A transparent adhesive film possessing selective permeability combined with a hydrogel (Burnshield) may be effective in burn patients to reduce skin maceration, improve medication, control pain more effectively, and reduce the incidence of late complications (hypertrophic scars). DESIGN: This is a prospective study; the mean follow-up in all patients was 28.4 months (range, 14-35 months). The external part of the film is impermeable to fluid and microorganisms, but allows transpiration of water vapor from the cutis. The permeability to water vapor of a semipermeable film in contact with liquids is measured in grams per meters squared every 24 hours at 37 degrees C, and is defined as the moisture vapor transmission rate. In this study, a film with a moisture vapor transmission rate of 1600 g/m(2) every 24 hours at 37 degrees C was used. PATIENTS: For about 2 years, this type of therapy was used in the first aid treatment of 48 burn patients, 4 of whom were lost during therapy and 4 of whom were unavailable for follow-up. INTERVENTIONS: The patients were treated with hydrogel and a semipermeable film at first medication, and some were treated in this way during subsequent medications. MAIN OUTCOME MEASURES: The mean reepithelialization time of all patients was 17 days (range, 4-60 days); 8 (20%) of 40 patients with complications were treated with a gel (Same Plast Gel). Late complications were observed: hypertrophic scars in 2 patients (5%) and dyschromic lesions in 6 (15%). RESULTS: The most frequent complication, which occurred at various stages during medication, was skin maceration (15 [34%] of 44 patients). Other complications recorded during therapy were infections in 2 patients (5%), vertigo in 1 patient (2%), and abundant fibrin production in 1 patient (2%). In some of the patients, associated diseases and/or conditions were found: hepatic cirrhosis, diabetes mellitus, epilepsy, and pregnancy (33rd week) (each found in 1 patient each). Four patients were sent to the burn unit, 3 with second-degree burns of the hand and 1 with first-/second-degree burns of the abdomen and thigh, with 12% of the total body surface area burned. CONCLUSIONS: In the reepithelialization phase, complications were recorded in 8 of the 40 patients: 7 (18%) had residual inflammation and 1 (2%) had a hypertrophic scar. During the follow-up, late complications were recorded in 2 (5%) of the 40 patients. A gel was used in 8 patients: in 6 of the 7 patients with residual inflammation, the complication resolved, while in 1, despite therapy, the residual inflammation evolved into hypertrophic scarring. Treatment with the gel in the 2 patients with late lesions reduced the thickness and extent of the lesions, with minimal aesthetic and functional damage.

Prevention of motion sickness with rizatriptan: a double-blind, placebo-controlled pilot study.
Med Sci Monit. 2006 Jan;12(1):PI1-7
Authors: Marcus DA, Furman JM
BACKGROUND: Serotonergic triptan medications effectively reverse pain and associated symptoms of migraine. Vestibular symptoms, including dizziness and vertigo, occur in about one-third of migraineurs. The most frequent and consistent balance symptom in migraineurs is motion sickness, which is experienced by about half of migraineurs and may be related to serotonergic influences. This double-blind, placebo-controlled, crossover pilot study was designed to test the hypothesis that pre-treatment with the serotonin agonist rizatriptan would prevent motion sickness provocation in headache-free migraineurs. MATERIAL/METHODS: Ten healthy adult migraineurs (5 migrainous vertigo and 5 migraine without associated vestibular symptoms) with a history of motion sickness were tested in three sessions: a baseline vestibular battery and two motion sickness provocation sessions two hours following randomly ordered blinded pre-treatment with either oral rizatriptan 10 mg or placebo. Motion sickness was assessed using two standardized questionnaires. RESULTS: Motion sickness scores were lower following pre-treatment with rizatriptan compared with placebo in subjects with migrainous vertigo. Rizatriptan did not affect motion sickness in migraineurs without vertigo. Otolith-ocular reflex sensitivity was reduced following pretreatment with rizatriptan in both groups. CONCLUSIONS: This is the first study in humans testing a triptan serotonin agonist as a preventive tool for motion sickness. Rizatriptan prevented the development of motion sickness and severe motion sickness symptoms in patients with migrainous vertigo. These pilot data suggest a possible role for serotonin in the development of motion sickness symptoms in migraineurs with migrainous vertigo.

Validation of the M?ni?re's Disease Patient-Oriented Symptom-Severity Index.
Arch Otolaryngol Head Neck Surg. 2005 Oct;131(10):863-7
Authors: Gates GA, Verrall AM
OBJECTIVE: To validate a disease-specific, health-related quality-of-life instrument for people with active, unilateral, cochleovestibular M?ni?re's disease (MD). DESIGN: Prospective, blinded, randomized cohort study using a 16-item instrument, the M?ni?re's Disease Patient-Oriented Symptom-Severity Index (MDPOSI), version 2. SETTING: Four clinical sites, including 3 university hospitals and 1 private practice. PARTICIPANTS: Sixty-one adult participants in a clinical trial of a new treatment modality (the Meniett device) at 4 medical centers. INTERVENTION: The MDPOSI was administered at baseline and at 2 and 4 months after the use of the Meniett device or the placebo. MAIN OUTCOME MEASURES: Each item, domain, and overall MDPOSI score was compared with self-reported cumulative frequency of definitive attacks of vertigo at baseline and 2 and 4 months later. RESULTS: The MDPOSI global score, domain scores, and 13 of 16 items were significantly associated with the frequency of vertigo (gold standard) as noted on the daily symptom report card. CONCLUSIONS: The MDPOSI is a valid and reliable instrument to evaluate the impact of MD on patients' disease-related quality of life, and it is responsive to change in the status of the disorder. The MDPOSI is suitable for use in clinical practice and clinical research in people with MD.

The impact of obesity on drug prescribing in primary care.
Br J Gen Pract. 2005 Oct;55(519):743-9
Authors:
BACKGROUND: Healthcare costs attributable to obesity have previously involved estimations based on costs of diseases commonly considered as having obesity as an underlying factor. AIM: To quantify the impact of obesity on total primary care drug prescribing. DESIGN OF STUDY: Review of computer generated and handwritten prescriptions to determine total prescribing volume for all drug classes. SETTING: Twenty-three general practice surgeries in the UK. METHOD: Stratified random selection of 1150 patients who were obese (body mass index [BMI]>30 kg/m(2)) and 1150 age and sex-matched controls of normal weight (BMI 18.5-<25 kg/m(2)). Retrospective review of medical records over an 18-month period. RESULTS: A higher percentage of patients who were obese, compared with those of normal weight, were prescribed at least one drug in the following disease categories: cardiovascular (36% versus 20%), central nervous system (46% versus 35%), endocrine (26% versus 18%), and musculoskeletal and joint disease (30% versus 22%). All of these categories had a P-value of <0.001. Other categories, such as gastrointestinal (24% versus 18%), infections (42% versus 35%), skin (24% versus 19%) had a P-value of <0.01, while respiratory diseases (18% versus 21%) had a P-value of <0.05. Total prescribing volume was significantly higher for the group with obesity and was increased in the region of two- to fourfold in a wide range of prescribing categories: ulcer healing drugs, lipid regulators, beta-adrenoreceptor drugs, drugs affecting the rennin angiotensin system, calcium channel blockers, antibacterial drugs, sulphonylureas, biguanides, non-steroidal anti-inflammatories (NSAIDs) (P<0.001) and fibrates, angiotensin II antagonists, and thyroid drugs (P<0.05). The main impact on prescribing volumes is from numbers of patients treated, although in some areas there is an effect from greater dosage or longer treatment in those who are obese including calcium channel blockers, antihistamines, hypnotics, drugs used in the treatment of nausea and vertigo, biguanides, and NSAIDs (P<0.05) reflected in significantly increased defined daily dose prescribing. CONCLUSIONS: This large study of contemporary practice indicates that obesity more than doubled prescribing in most drug categories.

Vestibular rehabilitation therapy for the dizzy patient.
Ann Acad Med Singapore. 2005 May;34(4):289-94
Authors: Tee LH, Chee NW
A customised vestibular rehabilitation therapy (VRT) programme is an important treatment modality in patients with vestibular dysfunction resulting in motion-provoked vertigo, oscillopsia (gaze instability), disequilibrium and gait disturbances. We discuss in this paper the patient selection criteria for VRT, rehabilitation strategies for unilateral and bilateral vestibular deficits, and some of the compelling evidence to support the use of VRT in treating such patients.

Etanercept therapy for immune-mediated cochleovestibular disorders: a multi-center, open-label, pilot study.
Arthritis Rheum. 2005 Jun 15;53(3):337-42
Authors: Matteson EL, Choi HK, Poe DS, Wise C, Lowe VJ, McDonald TJ, Rahman MU
OBJECTIVE: Immune-mediated cochleovestibular disorders (IMCVDs) continue to present a diagnostic and therapeutic challenge. Antirheumatic agents, commonly employed for IMCVDs, are associated with variable efficacy and sometimes with serious side effects. The objective of the current study was to preliminarily evaluate the efficacy of etanercept therapy for IMCVD. METHODS: In this open-label prospective pilot study, 23 patients with bilateral IMCVDs or symptoms of bilateral Meniere's disease were treated with etanercept (25 mg twice weekly, by subcutaneous injection) for 24 weeks. All participants showed progressive hearing loss within 3 months prior to the study and responded to prednisone therapy. Hearing improvement was defined as an improvement of sensorineural hearing from baseline, in at least one ear, of 15 dB or more in the pure-tone air conduction thresholds, or an increase of more than 12% in word identification score. When present, vertigo and tinnitus were assessed by frequency and severity of attack and a functional level scale. Limited serial positron emission tomography (PET) of the inner ear region was performed in 5 patients to assess disease activity. RESULTS: There were 12 female (52%) and 11 male patients with a mean age of 48 years. Hearing improved in 7 (30%) patients, was unchanged in 13 (57%), and worsened in 3 (13%). Of 21 patients with tinnitus, this symptom improved in 7 (33%), was unchanged in 10 (48%), and worsened in 3 (13%). Of 16 patients with vertigo, 8 (50%) were improved, 7 (47%) unchanged, and 1 (3%) worse at the end of the study. Etanercept was generally well tolerated. PET was positive on one ear of 2 of 5 patients, remained positive with treatment on 1 of these, and was initially positive in 1 deaf ear, becoming negative at followup. CONCLUSION: These prospective pilot data suggest that etanercept therapy is safe among patients with IMCVDs. However, these data do not suggest substantial efficacy of etanercept among patients with IMCVDs in improving hearing loss. There appeared to be stabilization or improvement of hearing in 87% in this group of patients with pretreatment intractable progressive hearing loss. However, the study endpoint of improvement in 70% of patients was not attained. This short-term effect of possible stabilization requires further study. PET scanning was not useful as a tool to evaluate hearing loss in a limited subset of patients.

Strategies to prevent recurrence of benign paroxysmal positional vertigo.
Arch Otolaryngol Head Neck Surg. 2005 Apr;131(4):344-8
Authors: Helminski JO, Janssen I, Kotaspouikis D, Kovacs K, Sheldon P, McQueen K, Hain TC
OBJECTIVE: To determine if a daily routine of Brandt-Daroff exercises increases the time to recurrence and reduces the rate of recurrence of benign paroxysmal positional vertigo (BPPV). DESIGN: Random sample of convenience and retrospective case review. SETTING: Tertiary referral center and outpatient clinic. PATIENTS: One hundred sixteen patients diagnosed with BPPV involving the posterior semicircular canal (BPPV-PC) who were successfully treated with the canalith repositioning procedure. INTERVENTIONS: Patients in the treatment group (n = 43) performed daily Brandt-Daroff exercises, while patients in the no-treatment group (n = 73) performed no exercises. MAIN OUTCOME MEASURES: Follow-up was as long as 2 years. Every 2 months patients were mailed a questionnaire. If BPPV had recurred, patients contacted the principal investigator within 24 hours. Within 1 to 2 weeks, patients were evaluated in the clinic with the Dix-Hallpike maneuver or, if unable to travel to the clinic, interviewed by telephone. RESULTS: Symptoms recurred in 50 (43%) of the 116 subjects, 34 (47%) of 73 in the no-treatment group and 16 (37%) of 43 in the treatment group. There was no significant difference in the frequency of recurrence (Pearson chi(2), P = .33) or time to recurrence (survival analysis, log-rank test, P = .92). A history of recurrent BPPV-PC did not affect frequency of recurrence (Pearson chi(2), P = .33) or time to recurrence (survival analysis, log-rank test, P = .72). CONCLUSION: Our results suggest that a daily routine of Brandt-Daroff exercises does not significantly affect the time to recurrence or the rate of recurrence of BPPV-PC.

Benign paroxysmal positional vertigo: clinical characteristics of dizzy patients referred to a Falls and Syncope Unit.
QJM. 2005 May;98(5):357-64
Authors: Lawson J, Johnson I, Bamiou DE, Newton JL
BACKGROUND: Dizziness is a common symptom in older people that affects quality of life and increases the risk of falls. Benign paroxysmal positional vertigo (BPPV) is a common cause of dizziness that increases in prevalence with age, and is potentially curable. AIM: To compare patients with BPPV referred initially to a Falls and Syncope Unit (FSS group) with those initially referred to a Regional ENT/Balance Service (ENT group). DESIGN: Retrospective case-note review. METHODS: Medical notes, investigations and outcomes were reviewed for all patients. RESULTS: Of 59 patients with BPPV confirmed by Dix-Hallpike test, 31 (53%) were initially referred to the FSS (2.6 patients per month, 71% females) and 28 (47%) were initially referred to ENT (4.7 patients per month, 86% females). Compared to those referred initially to ENT, FSS patients were significantly older (mean +/- SD 69 +/- 13 vs. 55.4 +/- 13 years, p = 0.0003) and had dizzy symptoms for longer before diagnosis (median (range) 12 (4-120) vs. 6 (1-36) months, p = 0.0273). FSS patients were more likely to have more than one type of dizziness (16% vs. 0%, p = 0.001), more likely to have cerebrovascular or cardiovascular co-morbidity (13% vs. 4%, p = 0.0152) and were taking significantly more medications (3.2 vs. 1.7; p = 0.0271). Cure rates on intervention were similar (83% FSS, 86% ENT). DISCUSSION: BPPV is a potentially curable cause for dizziness in older people. Older people are frequently referred directly to Falls units, who will be seeing increasing numbers of patients with dizziness. A high index of suspicion allows early identification and treatment of this condition.

Vertigo is the illusion of motion, usually rotational motion. As patients age, vertigo becomes an increasingly common presenting complaint. The most common causes of this condition are benign paroxysmal positional vertigo, acute vestibular neuronitis or labyrinthitis, M?ni?re's disease, migraine, and anxiety disorders. Less common causes include vertebrobasilar ischemia and retrocochlear tumors. The distinction between peripheral and central vertigo usually can be made clinically and guides management decisions. Most patients with vertigo do not require extensive diagnostic testing and can be treated in the primary care setting. Benign paroxysmal positional vertigo usually improves with a canalith repositioning procedure. Acute vestibular neuronitis or labyrinthitis improves with initial stabilizing measures and a vestibular suppressant medication, followed by vestibular rehabilitation exercises. Meniere's disease often responds to the combination of a low-salt diet and diuretics. Vertiginous migraine headaches generally improve with dietary changes, a tricyclic antidepressant, and a beta blocker or calcium channel blocker. Vertigo associated with anxiety usually responds to a selective serotonin reuptake inhibitor.

BACKGROUND: Post-herpetic neuralgia is difficult to treat. Divalproex sodium (valproic acid and sodium valproate in molar ratio 1:1) has been used successfully in the management of various painful neuropathies. AIM: To study the effectiveness and safety of divalproex sodium in the management of post-herpetic neuralgia. DESIGN: Randomized double-blind placebo-controlled trial. METHODS: We enrolled 48 consecutively attending out-patients with post-herpetic neuralgia, out of whom three were excluded (two had insufficient pain, one withdrew consent). Quantification of pain was by Short Form-McGill pain questionnaire (SF-MPQ), visual analogue scale (VAS), present pain intensity score (PPI) and 11 point Likert scale (11 PLS) at the beginning of the study, after 2 weeks, 4 weeks and at the end of the study (8 weeks). We also assessed patients' global impression of change by questionnaire at the end of the study. RESULTS: After 8 weeks treatment with 1000 mg/day divalproex sodium, there was significant reduction in pain: SF-MPQ, 20.47 +/- 2.29 to 11.90 +/- 6.52 (p < 0.0001); PPI 4.0 +/- 0.52 to 1.95 +/- 1.29 (p < 0.0001); VAS 70.17 +/- 9.21 to 31.27 +/- 29.74 (p < 0.0001) and 11 PLS 6.97 +/- 0.73 to 3.63 +/- 2.34 (p < 0.0001) in comparison to placebo (means +/- SEM). The 'global impression of change' questionnaire showed much or moderate improvement in pain in 58.2% of patients receiving divalproex vs. 14.8% of those receiving placebo. The drug was well tolerated by all patients, except one who developed severe vertigo after 10 days of treatment. DISCUSSION: Divalproex sodium provides significant pain relief in patients of post-herpetic neuralgia, with very little incidence of adverse reactions. These data provide a basis for longer trials in a larger group of patients.

Is posttraumatic benign paroxysmal positional vertigo different from the idiopathic form?
Arch Neurol. 2004 Oct;61(10):1590-3
Authors: Gordon CR, Levite R, Joffe V, Gadoth N
BACKGROUND: Although head trauma is considered a common cause of benign paroxysmal positional vertigo (BPPV), clinical presentation and outcome of traumatic BPPV (t-BPPV) have not been systematically evaluated. OBJECTIVES: To compare the clinical presentation, patient's response to physical treatment, and outcome of patients with t-BPPV with those with the idiopathic form (i-BBPV). SETTING: Tertiary referral neuro-otology outpatient clinic. METHODS: We reviewed the clinical records of 247 consecutive patients with posterior canal BPPV during the years 1997 to 2000. All patients were diagnosed using the Dix-Hallpike test and treated using the particle repositioning maneuver. Patients with an onset of positional vertigo within 3 days of well-documented head trauma were included in the t-BPPV group. The outcome was compared with the outcome of 42 patients with i-BPPV who were similarly treated and followed up. RESULTS: Twenty-one (8.5%) of the 247 patients with BPPV fulfilled the diagnostic criteria for t-BPPV. The most common cause of head trauma was motor vehicle crash, documented in 57% of the cases; half of the patients additionally suffered from a whiplash injury. While the other causes were diverse, common falls were predominant. Only 2 of the patients involved in motor vehicle crashes experienced brief loss of consciousness. Sixty-seven percent of patients with t-BPPV required repeated physical treatments for complete resolution of signs and symptoms in comparison to 14% of patients with i-BPPV (P<.001). During a mean +/-SD follow-up of 21.7 +/- 9.7 months, 57% of t-BPPV patients and 19% of i-BPPV controls had recurrent attacks (P<.004). CONCLUSIONS: The nature and severity of the traumas causing t-BPPV are diverse, ranging from minor head injuries to more severe head and neck trauma with brief loss of consciousness. It appears that t-BPPV is more difficult to treat than i-BPPV, and also has a greater tendency to recur.

Methylprednisolone, valacyclovir, or the combination for vestibular neuritis.
N Engl J Med. 2004 Jul 22;351(4):354-61
Authors: Strupp M, Zingler VC, Arbusow V, Niklas D, Maag KP, Dieterich M, Bense S, Theil D, Jahn K, Brandt T
BACKGROUND: Vestibular neuritis is the second most common cause of peripheral vestibular vertigo. Its assumed cause is a reactivation of herpes simplex virus type 1 infection. Therefore, corticosteroids, antiviral agents, or a combination of the two might improve the outcome in patients with vestibular neuritis. METHODS: We performed a prospective, randomized, double-blind, two-by-two factorial trial in which patients with acute vestibular neuritis were randomly assigned to treatment with placebo, methylprednisolone, valacyclovir, or methylprednisolone plus valacyclovir. Vestibular function was determined by caloric irrigation, with the use of the vestibular paresis formula (to measure the extent of unilateral caloric paresis) within 3 days after the onset of symptoms and 12 months afterward. RESULTS: Of a total of 141 patients who underwent randomization, 38 received placebo, 35 methylprednisolone, 33 valacyclovir, and 35 methylprednisolone plus valacyclovir. At the onset of symptoms there was no difference among the groups in the severity of vestibular paresis. The mean (+/-SD) improvement in peripheral vestibular function at the 12-month follow-up was 39.6+/-28.1 percentage points in the placebo group, 62.4+/-16.9 percentage points in the methylprednisolone group, 36.0+/-26.7 percentage points in the valacyclovir group, and 59.2+/-24.1 percentage points in the methylprednisolone-plus-valacyclovir group. Analysis of variance showed a significant effect of methylprednisolone (P<0.001) but not of valacyclovir (P=0.43). The combination of methylprednisolone and valacyclovir was not superior to corticosteroid monotherapy. CONCLUSIONS: Methylprednisolone significantly improves the recovery of peripheral vestibular function in patients with vestibular neuritis, whereas valacyclovir does not.

Color Doppler imaging of cervicocephalic fibromuscular dysplasia.
Cardiovasc Ultrasound. 2004;2:7
Authors: Arning C, Grzyska U
BACKGROUND: Fibromuscular dysplasia (FMD) is a possible cause of stroke, especially in middle-aged women. However, only few reports are available on ultrasonographic detection and monitoring. METHODS: Among the 15,000 patients who underwent color Doppler imaging (CDI) of the cervicocephalic arteries during the study period, all cases fulfilling ultrasound criteria of FMD were included into the case series. Criteria of FMD were: 1. Segmental string-of-beads pattern, 2. Localization in the distal extracranial part of internal carotid artery (ICA) or vertebral artery (VA), and 3. (optional): Direct and/or indirect criteria of stenosis. RESULTS: CDI detected FMD in 39 vessels (37 ICA and 2 VA segments) of 21 patients. 16 patients had bilateral manifestation on ICA, one of those also on VA, bilaterally. CDI disclosed 4 symptomatic high-grade ICA stenoses, 3 of them underwent endovascular treatment. 5 patients with moderate symptomatic ICA stenoses got medical treatment. In 6 patients FMD was the most likely cause of headache and in one patient FMD was diagnosed as a cause of vertigo. CONCLUSIONS: CDI may be used for detection of cervicocephalic FMD. Due to the unfavourable localisation of FMD for CDI, the sensitivity of CDI is lower in comparison to angiography. However, high-grade FMD stenoses that require invasive treatment can be recognized on the basis of indirect hemodynamic criteria.

The effects of transtympanic micropressure treatment in people with unilateral Meniere's disease.
Arch Otolaryngol Head Neck Surg. 2004 Jun;130(6):718-25
Authors: Gates GA, Green JD, Tucci DL, Telian SA
OBJECTIVE: To evaluate the efficacy of a portable low-intensity alternating pressure generator, the Meniett device, in controlling the symptoms of M?ni?re's disease. DESIGN: A randomized, placebo-controlled, double-blind, multicenter clinical trial of 4 months' duration. SETTING: Four study sites: 3 academic medical centers and 1 private practice. PATIENTS: Sixty-seven people aged 33 to 71 years with established, active, unilateral cochleovestibular M?ni?re's disease randomly assigned to a treatment or control group. Five cases were excluded (2 dropouts, 3 protocol violations), leaving 62 evaluable cases. INTERVENTION: The Meniett device was self-administered 3 times daily. The placebo Meniett device was identical but exerted no pressure. All participants had a tympanostomy tube inserted in the affected ear. MAIN OUTCOME MEASURES: Participants rated vertigo and activity each day on a symptom report card. Hearing tests, electrocochleography, and questionnaires were completed at baseline, 2 months, and 4 months. RESULTS: The treatment group experienced significantly less severe vertigo, fewer days with definitive vertigo, and fewer days lost from work (sick days) during the follow-up period than did the control group. Hearing and electrocochleographic results did not differ between the groups. Outcomes did not differ by age, gender, laterality, or duration of symptoms. Outcomes were affected by vestibular loss and baseline level of vertigo. The tympanostomy tube had no short-term effect on vertigo symptoms. There were no complications from using the Meniett device. CONCLUSION: The Meniett device is a minimally invasive, safe, and efficacious intermediate treatment for people with substantial vertigo uncontrolled by medical therapy.

Differences in diffusion-weighted and T2-weighted magnetic resonance imaging findings in the acute and chronic stages of ischemic cerebrovascular disease--two case reports.
Neurol Med Chir (Tokyo). 2004 May;44(5):245-8
Authors: Yamamoto J, Nishizawa S, Yamaguchi M, Akamine S, Tokuyama T, Sugiyama K, Namba H
A 71-year-old man presented with sudden onset of vertigo and a 77-year-old man suffered consciousness disturbance. Diffusion-weighted magnetic resonance (MR) imaging on admission showed hyperintense areas in the left cerebellar hemisphere in the first patient and in the brainstem in the second patient. Both patients were treated with argatroban and edaravone, and the neurological deficits markedly improved one month after admission. T2-weighted MR imaging one month after the onset showed much smaller hyperintense areas compared with the findings on admission in both patients. These results indicate that findings of hyperintense areas by diffusion-weighted MR imaging in the acute stage of ischemic cerebrovascular disease indicate not only the ischemic core but also parts of the reversible incomplete ischemic lesion and suggest that intensive treatment in the acute stage might reverse ischemic brain damage in some patients.

Persistent vertigo following particle repositioning maneuvers: an analysis of causes.
Arch Otolaryngol Head Neck Surg. 2004 Apr;130(4):436-9
Authors: Rupa V
OBJECTIVE: To analyze the causes of persistent vertigo following treatment with particle repositioning maneuvers (PRMs) in patients with benign paroxysmal positional vertigo. DESIGN: Prospective study of outcomes in patients with benign paroxysmal positional vertigo. STUDY SETTING: Outpatient clinic of a tertiary care referral center. PATIENTS: A sample of 90 consecutive patients with documented benign paroxysmal positional vertigo of the posterior semicircular canal who had persistent vertigo after at least 3 sessions of PRMs during a period of 2 weeks. INTERVENTION: Particle repositioning using a modified Epley maneuver. MAIN OUTCOME MEASURE: Persistent vertigo following at least 3 sessions of PRMs over a period of 2 weeks. RESULTS: Seven patients showed partial or no improvement following treatment. The causes subsequently determined included coincident horizontal canal positional vertigo (2 cases), M?ni?re's disease (2 cases), persistent posterior canal benign paroxysmal positional vertigo in association with cervical spondylosis (2 cases), and a posterior fossa meningioma (1 case). CONCLUSIONS: Patients with persistent or frequently recurring positional vertigo following treatment with PRMs should undergo detailed investigation to exclude coincidental pathology for which specific treatment is required. In patients in whom no coincident pathology requiring therapy is identified, treatment options other than the PRM already instituted should be considered.

This report presents a therapeutic procedure for refractory benign paroxysmal positional vertigo (antBPPV) of the anterior canal. Two patients with refractory antBPPV were treated by a prolonged forced position procedure (PFPP). The technique is based on the assumption that the pathophysiological mechanism of antBPPV is similar to that generating posterior canal canalolithiasis. The patients recovered from refractory antBPPV after one or more PFPPs. The rationale for this therapy is that when the patient lies in the proposed forced position, the affected anterior canal is uppermost in an almost gravitationally vertical position. If the patient remains in this position for several hours, the floating particles lying in the non-ampullary arm of the canal can gradually slip out of the canal towards the vestibule due to gravity. We recommend trying PFPP when the side of lithiasis cannot be determined, in cases that are resistant to particle repositioning canal manoeuvres, and before considering canal plugging for refractory antBPPV.

Paralytic complications of puffer fish (tetrodotoxin) poisoning.
Singapore Med J. 2004 Feb;45(2):73-4
Authors: Ahasan HA, Mamun AA, Karim SR, Bakar MA, Gazi EA, Bala CS
INTRODUCTION: Puffer fish is available in Bangladesh and is occasionally eaten by some people. Ignorance regarding its proper cooking process may lead to serious health hazards, including fatality. METHODS: An unusual catastrophic event happened recently in Khulna, Bangladesh that drew nationwide attention. Eight families were affected. RESULTS: Thirty-seven patients were admitted with a history of consumption of puffer fish. Peri-oral paraesthesia (24), weakness of both lower limbs (22), paraesthesia all over the body (18), headache (15), difficulty in respiration (14), nausea and vomiting (8), blurring of vision (7), and vertigo (6) were common clinical presentations. Twenty-two patients developed ascending paralysis of limbs and involved the respiratory muscles in 17 patients. Eight patients died due to respiratory failure while the rest improved. CONCLUSION: Health personnel should have sufficient knowledge regarding the clinical manifestations, complications and management of puffer fish poisoning. During its preparation, organs that contain the highest level of tetrodotoxin should be removed. Since there is no specific treatment, people should be made aware of the potential risk of eating puffer fish, about the warning symptoms and signs of puffer fish poisoning, and when to seek medical help.

BACKGROUND: Basilar artery occlusion usually causes severe disability or death. Until the recent developments in local intra-arterial or systemic intravenous fibrinolysis, interest in early diagnosis was low because there was no satisfactory treatment. Thus there is little information about the initial phase of the disease. OBJECTIVE: To report on the early clinical features and patterns of evolution of severe symptomatic basilar artery occlusion. METHODS: 24 patients with established basilar artery occlusion (confirmed by angiography or at necropsy) were reviewed retrospectively, focusing on the early clinical aspects and time course of the disease. RESULTS: The most common initial symptoms were motor deficits (16/24, including facial palsies), articulatory speech difficulties (15/24), vertigo, nausea or vomiting (13/24), and headaches (10/24). The most frequent objective initial findings were motor deficits (22/24), facial palsies (19/24), eye movement abnormalities (15/24), lower cranial nerve deficits (15/24), altered level of consciousness (12/24), and bilateral extensor plantar responses (9/24). Onset of the disease was gradual in nearly all patients and in half the warning signs were present for up to two months before the final stage. Headaches and visual disturbances were early signs, while speech difficulties and motor deficits were late signs. Once permanent neurological deficits were present, the final illness was reached within six hours in 41%, between six and 24 hours in 32%, and in two to three days in 27%. CONCLUSIONS: All the patients reviewed presented some symptoms and signs pointing to brain stem involvement. Only 8% (2/24) had an acute course with no adequate warning signs.

An 82-year-old man had deep, linear skin folds on the scalp. The patient did not have a history of neuropsychiatric disorders and was generally in good health except for diabetes mellitus, hypertension, and benign positional vertigo. Cutis verticis gyrata is a term used to describe the appearance of deep, linear skin folds in the scalp. Primary and secondary types of this condition exist. No treatment is typically needed, although surgical modalities may be beneficial for severely disfiguring types.

AIM: To analyze the development and occurrence of the idiopathic intracranial hypertension and consequent visual loss in a family affected with idiopathic intracranial hypertension. METHODS: We studied 15 members of the same family and found six of them affected with idiopathic intracranial hypertension, which was accompanied with visual loss as a repercussion of the disease. Idiopathic intracranial hypertension was diagnosed on neurological and radiological examination. Visual examination to establish visual loss included fundoscopy, visual acuity, visual field testing, and ultrasonography of the optic nerve. RESULTS: The construction of a family tree and detailed examination of 15 family members revealed idiopathic intracranial hypertension with visual disturbances, even amaurosis, and different stages of visual field constriction in three members of the family: the mother and her two daughters. Due to the symptoms of idiopathic intracranial hypertension, such as headaches, nausea, vertigo, and the presence of transient visual obscuration and papilledema, in three other members of this family (aged 16, 17, and 25 years), we considered a presumptive diagnosis of idiopathic intracranial hypertension, and the need for thorough follow-up. Medical data on the family grandmother, who died 34 years ago, suggested that she also had symptoms of idiopathic intracranial hypertension. One of the patients underwent surgical treatment by a lumbo-peritoneal shunt operation worsening of the symptoms. CONCLUSION: It is very important to include idiopathic intracranial hypertension in differential diagnosis of papilledema and recognize it in early stages to prevent vision loss. Current successful therapeutic approaches and close follow-up of such patients require teamwork of neurologists, ophthalmologists, and neurosurgeons.

Efficacy of the Semont maneuver in benign paroxysmal positional vertigo.
Arch Otolaryngol Head Neck Surg. 2003 Jun;129(6):629-33
Authors: Levrat E, van Melle G, Monnier P, Maire R
OBJECTIVES: To assess the efficacy of the Semont maneuver in the treatment of benign paroxysmal positional vertigo (BPPV) of the posterior semicircular canal and to evaluate the possible effect of various factors on the efficacy of this maneuver. DESIGN AND SETTING: Retrospective study in an outpatient clinic. PATIENTS: Two hundred seventy-eight patients presenting with symptomatic, unilateral BPPV of the posterior semicircular canal, exclusively treated with the Semont maneuver. INTERVENTIONS: During the first consultation, each patient was treated with a Semont maneuver. When BPPV persisted, this maneuver was repeated during follow-up visits, performed at weekly intervals. MAIN OUTCOME MEASURES: Patients were considered cured when vertigo disappeared within 30 days (allowing up to 4 maneuvers). RESULTS: More than 90% of patients were cured after a maximum of 4 maneuvers, and 83.5% were cured after only 2 maneuvers. The efficacy of the maneuver decreased each time it was repeated (from 62.6% at the first maneuver to 18.2% at the fourth). The duration of symptoms before initial consultation and the etiology of BPPV had a significant effect on the maneuver's efficacy (P<.001 and P =.002, respectively), whereas age (P =.12), sex (P =.06), and affected side (P =.20) had no effect. CONCLUSIONS: The Semont maneuver demonstrated a 90.3% cure rate after a maximum of 4 sessions. Patients consulting late (>6 months after the beginning of symptoms) or having traumatic BPPV had lower recovery rates than patients without these factors (74.7% vs 96.5%).

Postoperative sudden sensorineural hearing loss after posterior lumbar decompression: a case report.
Can J Anaesth. 2003 May;50(5):519-21
Authors: Mak PH, Tumber PS
PURPOSE: We report a case in which a patient sustained a dural tear during spinal surgery under general anesthesia complicated by a severe and persistent unilateral sensorineural hearing loss. CLINICAL FINDINGS: A 51-yr-old man with no previous otological history underwent a posterior lumbar decompression surgery in the prone position under general anesthesia. A small dural tear was discovered intra-operatively and was repaired by sutures. Surgery lasted for eight hours with over 3 L of blood loss. Recovery from anesthesia was otherwise uneventful. A unilateral right-sided sensorineural hearing loss was discovered shortly after completion of surgery. This was associated with mild tinnitus but no vertigo. There was no aural fullness, pain, headache or postural element to his symptoms. Despite extensive investigations, treatment and follow-up by an otorhinolaryngologist, his symptoms failed to improve 18 months following surgery. DISCUSSION: The possible etiologies, preventive strategies, prognosis and management plan of this rare complication are discussed.

BACKGROUND: Refugees and asylum seekers continue to enter the United States and the European Union in record numbers. Some have estimated that between 5-35% of all refugees have suffered torture in their countries of origin. Although general practitioners and specialized physicians are likely to encounter victims of torture as patients, few providers are familiar with the health problems that may affect this patient population. PURPOSE: :To provide neurologists, neurosurgeons, and rehabilitation medicine physicians with basic knowledge about survivors of torture that can help in the diagnosis, treatment, and referral of such patients. METHODS: A MEDLINE (1966-October 2001) search using keywords torture and sequelae (nervous system diseases and brain injuries) was conducted. Other data sources included books, reference lists, online resources and expert opinion. FINDINGS: :Forms of torture that may affect the nervous system include beatings, gunshot wounds, stab wounds, asphyxiation, prolonged suspension and electrocution. Victims of torture commonly experience neurological symptoms such as headaches, vertigo, loss of consciousness and dizziness during and after torture. A successful and meaningful clinical interaction with a survivor of torture includes avoiding retraumatization, building trust, spelling out any limits on confidentiality, and above anything else, establishing empathy with the patient. CONCLUSIONS: Neurological sequelae of torture can be devastating physically and psychologically. The treatment of these neurological conditions does not differ from other patient populations. However, the clinical approach is unique and must focus on avoiding retraumatization and helping the victim reintegrate into society as quickly as possible.

Double-blind controlled trial of gamma-hydroxybutyrate and clomethiazole in the treatment of alcohol withdrawal.
Alcohol Alcohol. 2002 Jan-Feb;37(1):67-73
Authors: Nimmerrichter AA, Walter H, Gutierrez-Lobos KE, Lesch OM
The aim of this double-blind, comparative study was to assess the efficacy and safety of gamma-hydroxybutyrate (GHB) in ameliorating the symptoms of alcohol withdrawal. Newly admitted alcohol-dependent patients (n = 98) were randomized to receive either clomethiazole 1000 mg daily (CLO group) (n = 33), or 50 mg GHB/kg body wt (n = 33) or 100 mg GHB/kg body wt (n = 32). This dose was administered for 5 days, halved on day 6, and on days 7 and 8 only placebo was given. As CLO is available as capsules and GHB as syrup, a double-dummy method was used to try to ensure blindness. The groups were matched in terms of baseline demographic and alcohol-related variables. There was no difference between the three treatments in ratings of alcohol withdrawal symptoms nor requests for additional medication. After tapering off the active medication, there was no increase in withdrawal symptoms, indicating that physical tolerance did not develop to either GHB or CLO within the 5-day treatment period. The most frequently reported side-effect of GHB was transient vertigo, particularly after the evening double dose.

The strict definition of the Ramsay Hunt syndrome is peripheral facial nerve palsy accompanied by an erythematous vesicular rash on the ear (zoster oticus) or in the mouth. J Ramsay Hunt, who described various clinical presentations of facial paralysis and rash, also recognised other frequent symptoms and signs such as tinnitus, hearing loss, nausea, vomiting, vertigo, and nystagmus. He explained these eighth nerve features by the close proximity of the geniculate ganglion to the vestibulocochlear nerve within the bony facial canal. Hunt's analysis of clinical variations of the syndrome now bearing his name led to his recognition of the general somatic sensory function of the facial nerve and his defining of the geniculate zone of the ear. It is now known that varicella zoster virus (VZV) causes Ramsay Hunt syndrome. Compared with Bell's palsy (facial paralysis without rash), patients with Ramsay Hunt syndrome often have more severe paralysis at onset and are less likely to recover completely. Studies suggest that treatment with prednisone and acyclovir may improve outcome, although a prospective randomised treatment trial remains to be undertaken. In the only prospective study of patients with Ramsay Hunt syndrome, 14% developed vesicles after the onset of facial weakness. Thus, Ramsay Hunt syndrome may initially be indistinguishable from Bell's palsy. Further, Bell's palsy is significantly associated with herpes simplex virus (HSV) infection. In the light of the known safety and effectiveness of antiviral drugs against VZV or HSV, consideration should be given to early treatment of all patients with Ramsay Hunt syndrome or Bell's palsy with a 7-10 day course of famciclovir (500 mg, three times daily) or acyclovir (800 mg, five times daily), as well as oral prednisone (60 mg daily for 3-5 days). Finally, some patients develop peripheral facial paralysis without ear or mouth rash, associated with either a fourfold rise in antibody to VZV or the presence of VZV DNA in auricular skin, blood mononuclear cells, middle ear fluid, or saliva. This indicates that a proportion of patients with "Bell's palsy" have Ramsay Hunt syndrome zoster sine herpete. Treatment of these patients with acyclovir and prednisone within 7 days of onset has been shown to improve the outcome of recovery from facial palsy.

Possible estuary-associated syndrome: symptoms, vision, and treatment.
Environ Health Perspect. 2001 May;109(5):539-45
Authors: Shoemaker RC, Hudnell HK
The human illness designated as possible estuarine-associated syndrome (PEAS) by the Centers for Disease Control and Prevention (CDC) has been associated with exposure to estuaries inhabited by toxin-forming dinoflagellates, including members of the fish-killing toxic Pfiesteria complex (TPC), Pfiesteria piscicida and Pfiesteria shumwayae. Humans may be exposed through direct contact with estuarine water or by inhalation of aerosolized or volatilized toxin(s). The five cases reported here demonstrate the full spectrum of symptoms experienced during acute and chronic stages of this suspected neurotoxin-mediated illness. The nonspecific symptoms most commonly reported are cough, secretory diarrhea, headache, fatigue, memory impairment, rash, difficulty in concentrating, light sensitivity, burning skin upon water contact, muscle ache, and abdominal pain. Less frequently encountered symptoms are upper airway obstruction, shortness of breath, confusion, red or tearing eyes, weakness, and vertigo. Some patients experience as few as four of these symptoms. The discovery that an indicator of visual pattern-detection ability, visual contrast sensitivity (VCS), is sharply reduced in affected individuals has provided an objective indicator that is useful in diagnosing and monitoring PEAS. VCS deficits are present in both acute and chronic PEAS, and VCS recovers during cholestyramine treatment coincident with symptom abatement. Although PEAS cannot yet be definitively associated with TPC exposure, resolution with cholestyramine treatment suggests a neurotoxin-mediated illness.

Open trial of methotrexate as treatment for autoimmune hearing loss.
Arthritis Rheum. 2001 Apr;45(2):146-50
Authors: Matteson EL, Fabry DA, Facer GW, Beatty CW, Driscoll CL, Strome SE, McDonald TJ
OBJECTIVE: To assess the efficacy of low-dose methotrexate (MTX) administered for the treatment of autoimmune hearing loss. METHODS: This was a prospective, 12-month, open-label study of 17 patients with refractory autoimmune hearing loss. All patients had ongoing episodic worsening of hearing in one or both ears prior to enrollment despite traditional medical therapy. The MTX dose was 7.5-25 mg/week. Hearing loss and vertigo were evaluated at baseline and at completion of the study. Hearing improvement was defined as an improvement in pure tone threshold (PT) average of >10 dB or an increase in speech discrimination (SD) of >15%; worsening was defined as a decrease of >10 dB in PT or a decrease of >15% in SD in at least one ear. RESULTS: MTX was well tolerated. Among patients with Meniere's disease, 5 of 9 had improvement or resolution of vertigo. Equilibrium improved in all 3 patients with Cogan's syndrome and improved in 2 out of 3 patients with idiopathic hearing loss and this symptom. According to the parameters defined above, hearing improved in 11 patients (65%), was unchanged in 4 patients (23%), and worsened in 2 patients (12%). CONCLUSION: Long-term low-dose MTX therapy may be a useful therapy for at least some patients who have hearing loss with a presumptively autoimmune-mediated component that is refractory to traditional therapies.

OBJECTIVE: To establish specific criteria by which selective serotonin reuptake inhibitor (SSRI) discontinuation syndrome may be identified. DATA SOURCES: MEDLINE and PSYCHLIT databases were searched for case reports published from 1986 to 1997 inclusive, and references of relevant articles were also searched. STUDY SELECTION: Forty-six case reports of symptoms following the discontinuation of fluoxetine, fluvoxamine, paroxetine or sertraline were selected. Three studies of SSRI discontinuation were also reviewed. DATA EXTRACTION: Demographic and treatment information, as well as the timing, duration, number, nature and frequency of dicontinuation symptoms. DATA SYNTHESIS: Paroxetine was most frequently implicated. The drug had been tapered in half of the cases. In some cases, symptom onset began during taper, whereas, in most cases, symptoms began within 1 to 3 days of drug discontinuation. Fifty-three different symptoms were reported, with dizziness being the most common. Other common symptoms were nausea or emesis, fatigue, headache, gait instability and insomnia. Shock-like sensations, paresthesia and visual disturbances were the most rare. Without intervention, symptoms persisted for more than a week in half of the cases. In cases in which the SSRI was restarted, symptoms resolved within 72 hours. In some cases, withdrawal symptoms recurred when the same SSRI was again discontinued. CONCLUSIONS: Findings were used to construct diagnostic criteria for the SSRI discontinuation syndrome. These criteria are 2 or more of the following symptoms developing within 1 to 7 days of discontinuation or reduction in dosage of an SSRI after at least 1 month's use, when these symptoms cause clinically significant distress or impairment and are not due to a general medical condition or recurrence of a mental disorder: dizziness, light-headedness, vertigo or feeling faint; shock-like sensations or paresthesia; anxiety; diarrhea; fatigue; gait instability; headache; insomnia; irritability; nausea or emesis; tremor; and visual disturbances.

Vibration does not improve results of the canalith repositioning procedure.
Arch Otolaryngol Head Neck Surg. 2000 May;126(5):617-22
Authors: Hain TC, Helminski JO, Reis IL, Uddin MK
OBJECTIVE: To determine whether, in patients with benign paroxysmal positional vertigo (BPPV), the canalith repositioning procedure performed with vibration applied over the mastoid bone of the affected ear is more effective in resolving the symptoms and preventing recurrence of BPPV than the procedure performed without vibration. DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Ninety-four patients diagnosed as having BPPV involving the posterior semicircular canal. INTERVENTIONS: Patients were assigned to one of 2 treatment groups: the canalith repositioning procedure with vibration (n=44) and with no vibration (n=50). MAIN OUTCOME MEASURES: Effectiveness of treatment was determined through clinical reevaluation or reported through a telephone interview 1 week after treatment. Intensity of symptoms was quantified on a scale of 1 to 3 (mild, moderate, or severe); effectiveness of treatment was categorized on a scale of 1 to 4 (cure, much better, better, or no change). Rate of recurrence was determined through later clinical reevaluation or a telephone interview. RESULTS: At 1 week, 57 of the 94 patients were cured and 16 were much better, providing a 78% overall success rate. There was no significant difference in effectiveness of the treatment or the frequency of reoccurrence of BPPV between the vibration and no-vibration groups as determined from the Kaplan-Meier product-limit method and log-rank test. Rate of recurrence was 47% at a maximum follow-up of 5.25 years. CONCLUSIONS: Our results suggest that, while the canalith repositioning procedure is effective in the treatment of BPPV, vibration applied during the maneuver does not significantly affect short-term or long-term outcomes.

Outcome of symptoms of dizziness in a general practice community sample.
Fam Pract. 1999 Dec;16(6):616-8
Authors: Nazareth I, Yardley L, Owen N, Luxon L
BACKGROUND: Dizziness is commonly experienced in the community, but little is known about the long-term progression of the condition. OBJECTIVE: We aimed to assess over 18 months the outcome of symptoms of dizziness in a sample of patients identified from London general practices. METHOD: We followed up at 18 months a cohort of patients who reported symptoms of dizziness with or without anxiety, panic reactions or avoidance of situations that provoked the symptoms. The subjects completed a structured questionnaire both at baseline and at 18 months. RESULTS: At 18 months, 24% (95% CI = 23.5-34.8%) were more handicapped and 20% (95% CI = 15.2-25.2%) had recurrent dizziness, while 20% (95% CI = 14.9-24.8%) had improved. Patients with significant dizziness were more likely to consult their GP (OR = 14.4, 95% CI = 7.0-29.1) and were more likely to receive treatment (OR = 7.8, 95% CI = 3.2-22.4) or be referred to hospital (OR = 8.4, 95% CI = 3.2-22.4). The independent predictors of handicapping dizziness at 18 months were a history of fainting (OR = 2.4, 95% CI = 1.2-4.7), vertigo (OR = 2.6, 95% CI = 1.3-5.0) and avoidance of a situation that provoke dizziness (OR = 4.8, 95% CI = 2.5-9.0). CONCLUSION: Four per cent of all patients registered with a GP suffer persistent symptoms of dizziness and at least 3% are severely incapacitated by their symptoms. The presence of vertigo, fainting and avoidance in a person with dizziness is predictive of chronic handicapping dizziness. Further research is required on the progressions of symptoms of dizziness in a sample of GP attenders and those in the community.

A Phase I and pharmacokinetic study of TNP-470 administered weekly to patients with advanced cancer.
Clin Cancer Res. 1999 Aug;5(8):1989-95
Authors: Bhargava P, Marshall JL, Rizvi N, Dahut W, Yoe J, Figuera M, Phipps K, Ong VS, Kato A, Hawkins MJ
A Phase I study of angiogenesis inhibitor TNP-470 was conducted in patients with advanced cancer. TNP-470 (25-235 mg/m2) was administered i.v. over 4 h once a week to patients who had solid tumors refractory to the best available treatment or with a high risk of recurrence and who had normal renal, hepatic, and hematological function and no evidence of coagulopathy. The aims of the study were to determine the maximum tolerated dose, dose-limiting toxicities (DLTs), and the pharmacokinetics of TNP-470 given on a once-weekly schedule. Thirty-six patients, ages 23-75 (median, 54 years), with an Eastern Cooperative Oncology Group performance status of 0-2 were treated. The number of patients at each dose level (mg/m2) were 6 (25), 3 (50), 3 (75), 3 (100), 3 (133), 12 (177), and 6 (235). The principal toxicities of TNP-470 were dizziness, lightheadedness, vertigo, ataxia, decrease in concentration and short-term memory, confusion, anxiety, and depression, which occurred at doses of 133, 177, and 235 mg/m2. Two patients treated at 235 mg/m2 experienced DLT in the form of grade III cerebellar neurotoxicity after 6 weeks of treatment. Overall, these neurological symptoms were dose-related, had an insidious onset, progressively worsened with treatment, and resolved completely within 2 weeks of stopping the drug. One patient with malignant melanoma had stabilization of the previously growing disease for 27 weeks while on the treatment. Two patients, one with adenocarcinoma of the colon and the other with a soft tissue sarcoma, had no clinically detectable disease but were at high risk for recurrence at the initiation of treatment and received 13 months and > 3 years of treatment, respectively, with no evidence of disease recurrence. The remaining patients had progression of their disease after 1-6 months of treatment. The mean plasma half-life (t(1/2)) of TNP-470 and its principal metabolite, AGM-1883, were extremely short (harmonic mean, t(1/2) of 2 and 6 min, respectively) with practically no drug detectable in the plasma by 60 min after the end of the infusion. MII, an inactive metabolite, had a considerably longer t(1/2) of approximately 2.6 h. Mean peak TNP-470 concentrations were > or = 400 ng/ml at doses > or = 177 mg/m2. On the basis of this study, the maximum tolerated dose of TNP-470 administered on a weekly schedule was 177 mg/m2 given i.v over 4 h. The principal DLT was neurotoxicity, which appeared to be dose-related and was completely reversible. On the basis of the short plasma t(1/2) of TNP-470, exploration of a prolonged i.v. infusion schedule is warranted.

Physiatric management of mild traumatic brain injury.
Mt Sinai J Med. 1999 May;66(3):152-9
Authors: Flanagan S
Mild traumatic brain injury (MTBI) is a common condition, afflicting as many as 1.5 million Americans yearly. Most individuals sustain MTBI as a result of motor vehicle collisions, but it may also occur as a result of falls, physical assault or sporting accidents. Problems related to MTBI include various pain syndromes, cognitive impairments, disorders of affect, cranial nerve dysfunction, and vertigo, arising from injury to the brain, head, or cervical spine. Symptoms are usually transient, although a small percentage of afflicted individuals develop long-lasting problems, often preventing them from leading productive lives. Recognition of these problems as arising from MTBI is difficult due to the frequent lack of abnormal findings on diagnostic tests and failure to identify a history of head trauma. The American Congress of Rehabilitation Medicine has defined MTBI, an important first step in identifying individuals who need treatment. Diagnosis is usually made by directed questions regarding trauma history and careful procurement and interpretation of appropriate tests. Once a diagnosis is made, proper care can be prescribed in order to lead patients toward more productive lives.

Homeopathic vs conventional treatment of vertigo: a randomized double-blind controlled clinical study.
Arch Otolaryngol Head Neck Surg. 1998 Aug;124(8):879-85
Authors: Weiser M, Str?sser W, Klein P
OBJECTIVE: To compare the efficacy and safety of a homeopathic remedy (Vertigoheel, Heel Inc, Albuquerque, NM) vs betahistine hydrochloride (active control) in the treatment of patients with vertigo of various origins in a confirmative equivalence trial. DESIGN: Randomized (1:1) double-blind controlled clinical trial. SETTING: Fifteen study centers (general practice) in Germany between November 1995 and November 1996. SUBJECTS: A total of 119 patients with vertigo of various origins (from whom 105 patients could be analyzed as intended per protocol). MAIN OUTCOME MEASURES: Frequency, duration, and intensity of vertigo attacks. RESULTS: Both homeopathic and conventional treatments showed a clinically relevant reduction in the mean frequency, duration, and intensity of the vertigo attacks. The therapeutic equivalence of the homeopathic remedy and betahistine was established statistically. CONCLUSIONS: Concerning the main efficacy variable, therapeutic equivalence between the homeopathic remedy and betahistine could be shown with statistical significance (confirmative analysis). Both remedies reduced the frequency, duration, and intensity of vertigo attacks during a 6-week treatment period. Also, vertigo-specific complaints were significantly reduced in both treatment groups.

BACKGROUND: 'Vestibular rehabilitation' (VR) is an increasingly popular treatment option for patients with persistent dizziness. Previous clinical trials have only evaluated the effects of specialist therapy programmes in small, selective, or uncontrolled patient samples. AIM: To determine the benefits of VR compared with standard medical care, using a brief intervention for dizzy patients in primary care. METHOD: Adults consulting their general practitioner (GP) with dizziness or vertigo were randomly assigned to treatment or control groups. Patients in both groups received the same evaluation at baseline, six-week follow-up, and six-month follow-up, comprising examination of nystagmus, postural control, and movement-provoked dizziness, and a questionnaire assessment of subjective status, symptoms, handicap, anxiety, and depression. At baseline and six weeks later, the treatment group also received an individualized 30-minute therapy session, in which they were taught head, eye, and body exercises designed to promote vestibular compensation and enhance skill and confidence in balance. RESULTS: The treatment group (n = 67) improved on all measures, whereas the control group (n = 76) showed no improvement, resulting in a significant difference between the two groups on physical indices of balance and subjective indices of symptoms and distress. Odds ratios for improvement in treated patients relative to untreated patients were 3.1:1 at six weeks (95% CI = 1.4-6.8) and 3.8:1 at six months (95% CI = 1.6-8.7). CONCLUSION: VR is a simple, inexpensive, and beneficial treatment, and may be an appropriate first stage of management for many dizzy patients in primary care.

Prevalence and presentation of dizziness in a general practice community sample of working age people.
Br J Gen Pract. 1998 Apr;48(429):1131-5
Authors: Yardley L, Owen N, Nazareth I, Luxon L
BACKGROUND: Dizziness is known to be a common, handicapping condition in the elderly, and a strong association between dizziness and anxiety disorders has been observed in hospital samples. However, little is known about the prevalence of dizziness among people of working age in the community and its implications for psychosocial functioning and general practice consultation and treatment. AIM: To determine the prevalence of dizziness, giddiness, vertigo, and unsteadiness, and associations with disability and handicap, symptoms of panic and agoraphobia, and general practice consultation and treatment. METHOD: Postal questionnaires were completed by 2064 people aged 18-64 years randomly sampled from the patient lists of four London practices. Validated survey items were used to assess symptoms, panic and agoraphobia, levels of occupational disability and handicap, and general practice consultation and treatment. RESULTS: More than one in five responders (n = 480) had experienced dizziness during the past month; nearly half of these (n = 225) reported some degree of handicap and 30% had been dizzy for more than five years. Almost half (n = 221) of those with dizziness also reported anxiety and/or avoidance behaviour. Multiple physical and psychological symptoms were associated with higher levels of handicap. Only one in four of the 225 dizzy responders reporting some degree of handicap had received any form of treatment. CONCLUSION: Dizziness is a common, chronic, and often untreated symptom in people aged 18-65 years, associated with extensive handicap and psychological morbidity.

Diagnosis of stroke by the nonneurologist. A validation study.
Stroke. 1998 Jun;29(6):1106-9
Authors: Ferro JM, Pinto AN, Falc?o I, Rodrigues G, Ferreira J, Falc?o F, Azevedo E, Canh?o P, Melo TP, Rosas MJ, Oliveira V, Salgado AV
BACKGROUND AND PURPOSE: The first medical contact of an acute stroke victim is often a nonneurologist. Validation of stroke diagnosis made by these medical doctors is poorly known. The present study seeks to validate the stroke diagnoses made by general practitioners (GPs) and hospital emergency service physicians (ESPs). METHODS: Validation through direct interview and examination by a neurologist was performed for diagnoses of stroke made by GPs in patients under their care and doctors working at the emergency departments of 3 hospitals. RESULTS: Validation of the GP diagnosis was confirmed in 44 cases (85%); 3 patients (6%) had transient ischemic attacks and 5 (9%) suffered from noncerebrovascular disorders. Validation of the ESP diagnosis was confirmed in 169 patients (91%); 16 (9%) had a noncerebrovascular diagnosis. Overall, the most frequent conditions misdiagnosed as stroke were neurological in nature (cerebral tumor, 3; subdural hematoma, 1; seizure, 1; benign paroxysmal postural vertigo, 1; peripheral facial palsy, 2; psychiatric condition, 6; and other medical disorders, 7). CONCLUSIONS: In the majority of cases, nonneurologists (either GPs or ESPs) can make a correct diagnosis of acute stroke. Treatment of acute stroke with drugs that do not cause serious side effects can be started before evaluation by a neurologist and CT scan.

Treatment of MPS VII (Sly disease) by allogeneic BMT in a female with homozygous A619V mutation.
Bone Marrow Transplant. 1998 Mar;21(6):629-34
Authors: Yamada Y, Kato K, Sukegawa K, Tomatsu S, Fukuda S, Emura S, Kojima S, Matsuyama T, Sly WS, Kondo N, Orii T
A 12-year-old girl with Sly disease (mucopolysaccharidosis VII; beta-glucuronidase deficiency), who is homozygous for the A619V mutation, had a successful allogeneic BMT, donored by an HLA-identical unrelated female to replace the deficient enzyme. Within 5 months after BMT, the enzyme activity of the recipient's lymphocytes increased to normal range. No signs of acute or chronic GVHD were observed. For the successive 31 months post-BMT, beta-glucuronidase activity in her lymphocytes was maintained at almost normal levels and excretion of glycosaminoglycans in the urine was greatly diminished. Ultrastructural findings demonstrated no abnormal vacuoles and inclusion bodies in the cytoplasm of her rectal mucosal cells. Coincident with the restoration of the enzyme activity, clinical improvement was dramatic. Especially notable were improvements in motor function. The patient was able to walk alone for a long time without aid, and she even became able to ride a bicycle and take a bath. In addition, recurrent infections of the upper respiratory tract and the middle ears decreased in frequency and severity, and dyspnea on exertion, severe snoring and vertigo have substantially improved. Thus, allogeneic BMT in this patient produced a better quality of life and provided a more promising outlook.

Sound- and/or pressure-induced vertigo due to bone dehiscence of the superior semicircular canal.
Arch Otolaryngol Head Neck Surg. 1998 Mar;124(3):249-58
Authors: Minor LB, Solomon D, Zinreich JS, Zee DS
OBJECTIVES: To present symptoms, patterns of nystagmus, and computed tomographic scan identification of patients with sound- and/or pressure-induced vertigo due to dehiscence of bone overlying the superior semicircular canal. To describe anatomical findings and outcome in 2 patients undergoing plugging of the superior semicircular canal for treatment of these symptoms. DESIGN AND SETTING: Prospective study of a case series in a tertiary care referral center. PATIENTS AND RESULTS: Eight patients with vertigo, oscillopsia, and/or disequilibrium related to sound, changes in middle ear pressure, and/or changes in intracranial pressure were identified in a 2-year period. Seven of these patients also had vertical-torsional eye movements induced by these sound and/or pressure stimuli. The direction of the evoked eye movements could be explained by excitation or inhibition of the superior semicircular canal in the affected ear. Computed tomographic scans of the temporal bones identified dehiscence of bone overlying the affected superior semicircular canal in each case. Disabling disequilibrium in 2 patients prompted plugging of the dehiscent superior canal through a middle cranial fossa approach. Symptoms were improved in each case. One patient developed recurrent symptoms requiring an additional plugging procedure and developed sensorineural hearing loss several days after this second procedure. CONCLUSIONS: We have identified patients with a syndrome of vestibular symptoms induced by sound in an ear or by changes in middle ear or intracranial pressure. These patients can also experience chronic disequilibrium. Eye movements in the plane parallel to that of the superior semicircular canal were evoked by stimuli that have the potential to cause ampullofugal or ampullopetal deflection of this canal's cupula in the presence of a dehiscence of bone overlying the canal. The existence of such deshiscences was confirmed with computed tomographic scans of the temporal bones. Surgical plugging of the affected canal may be beneficial in patients with disabling symptoms.

Cerebellar infarction with hydrocephalus caused by spontaneous extracranial vertebral artery dissection--case report.
Neurol Med Chir (Tokyo). 1997 Jul;37(7):538-41
Authors: Sagoh M, Hirose Y, Murakami H, Katayama M, Akaji K, Mayanagi K
A 38-year-old male suffered sudden onset of rotational vertigo without headache. Consciousness disturbance developed on the 3rd day after the onset. Computed tomography showed cerebellar infarction with obstructive hydrocephalus. External ventricular drainage was performed. Angiography showed bilateral extracranial vertebral artery dissection. Antiplatelet therapy was given. Repeat angiography showed improvement of the dissection. His neurological deficits completely resolved. Vertebral artery dissections may cause both lateral medullary or cerebellar infarction and hydrocephalus due to the cerebellar infarction manifesting as various symptoms so careful evaluation and treatment are required.

Acetazolamide-responsive episodic ataxia in an Italian family refines gene mapping on chromosome 19p13.
Brain. 1997 May;120 ( Pt 5):805-12
Authors: Calandriello L, Veneziano L, Francia A, Sabbadini G, Colonnese C, Mantuano E, Jodice C, Trettel F, Viviani P, Manfredi M, Frontali M
Episodic ataxia type 2 is an autosomal dominant disorder with attacks of vertigo and ataxia which respond to acetazolamide treatment. The gene, distinct from the KCNA1 responsible for episodic ataxia type 1, has been mapped on chromosome 19p13 in a 11-12 cM region. A large Italian kindred affected with acetazolamide-responsive episodic ataxia is reported, with onset in adulthood, a strong vestibular component during attacks and a high frequency of cerebellar vermis degeneration. The genetic analysis (i) showed strong linkage between the disease and the 19p13 microsatellite markers in a region which widely overlaps that previously reported and (ii) set a new distal boundary of the gene-containing region. Combining present and previous mapping data, the gene of episodic etaxia type 2 is most probably located in an interval approximately 1.5 Mb between markers D19S221 and D19S226.

Clomiphene citrate as a possible cause of a psychotic reaction during infertility treatment.
Hum Reprod. 1997 Apr;12(4):706-7
Authors: Siedentopf F, Horstkamp B, Stief G, Kentenich H
Secondary side-effects often occur in women undergoing hormonal stimulation treatment with clomiphene citrate. In general 10.4% of women experience hot flushing, 5.5% have complaints caused by enlargement of the ovaries and 3.5% experience central nervous symptoms (nervousness, sleeplessness, headaches, visual disturbances, vertigo). During ovarian stimulation with clomiphene citrate for in-vitro fertilization, a 32 year old patient developed psychotic symptoms, commencing 3 days after initiation of treatment. Hospitalization in the psychiatric ward became necessary when severe formal and rational thought disturbances arose together with perceptory and sensory delusions. Under neuroleptic treatment the symptoms improved. Nevertheless, follow-up psychiatric care on an outpatient basis was deemed necessary. The infertility treatment was continued with human menopausal gonadotrophin stimulation. Psychiatric instability occurred neither at this point nor during the 2 year follow-up observation period. Both an exogenous psychosis (ICD F23.9) as well as the exacerbation of an endogenous psychosis (ICD F29) may be considered for the differential diagnosis. The stimulation with clomiphene citrate in connection with the physical and psychic stress of the infertility therapy can be regarded as the trigger factor. For patients with evidence of psychiatric illness in their case history, ovulation-inducing substances such as clomiphene citrate should be implemented with particular care.

Proximal ligation of large distal posterior inferior cerebellar artery aneurysm.
Neurol Med Chir (Tokyo). 1996 Jan;36(1):31-5
Authors: Yamaguchi N, Miyazaki H, Ishiyama N, Toya S
A 41-year-old male presented with vertigo, nausea, and vomiting suggesting a space-occupying lesion of the posterior fossa. Computed tomography (CT) and left vertebral angiography revealed a large distal posterior inferior cerebellar artery (PICA) aneurysm. Operation revealed the fusiform aneurysm was partially embedded in the medulla, preventing neck clipping or trapping of the aneurysm. Therefore, proximal ligation of the PICA was performed. The symptoms caused by the mass effect improved, and the aneurysm was not visualized by CT or angiography. Ligation of the PICA proximal to the choroidal point is not necessarily safe. In our case, ligation was distal to the tonsillomedullary segment from which the perforating arteries mainly arose, so the postoperative course was good without new neurological deficits. Proximal ligation is an effective treatment for distal PICA aneurysms manifesting as mass effect if other interventions are not possible.

Slow-flow vascular malformations of the pons: capillary telangiectasias?
AJNR Am J Neuroradiol. 1996 Jan;17(1):71-8
Authors: Barr RM, Dillon WP, Wilson CB
PURPOSE: To report clinical and MR features that suggest telangiectatic vascular malformations of the pons: METHODS: The MR scans and clinical data of 12 patients demonstrating an enhancing pontine lesion with minimal or no signal abnormality on T2-weighted images were reviewed. None of the patients underwent angiography or biopsy. Follow-up scans, available for all patients between 3 weeks and 40 months (range, 11.5 months), were reviewed. RESULTS: The patients presented with a variety of symptoms including headache (n = 4), vertigo (n = 3), gait abnormality (n = 3), and hearing loss (n = 2). Two were referred for biopsy or treatment of presumed pontine glioma. On precontrast MR, 3 of 12 lesions were isointense on both T1- and T2-weighted images. Three of 12 lesions were slightly hypointense on T1-weighted images and 8 of 12 were slightly hyperintense on T2-weighted images. Postgadolinium images showed a discrete focus of enhancement with irregular or brushlike borders. Eight of 12 had an anomalous draining vessel from the lesion to the surface of the pons. None demonstrated mass effect or hemorrhage. Gradient-echo sequences in 7 patients all showed marked T2 shortening, despite the absence of hemorrhage on either T1- or T2-weighted images. None of the follow-up scans showed radiographic or clinical progression. CONCLUSION: The benign clinical course, lack of mass effect, and minimal or no T2 prolongation argue against neoplasm and instead indicate a vascular cause. We suspect the decreased signal on gradient-echo sequences represents elevated intravascular deoxyhemoglobin from stagnant blood flow. The findings are atypical for cavernous angioma or classic venous malformation. Although pathologic confirmation is lacking, the radiographic features are most consistent with capillary telangiectasia or a transitional capillary-venous malformation. Despite the absence of progression or hemorrhage in any of the patients to date, the long-term prognosis currently is unknown. We emphasize the importance of recognizing the nonneoplastic nature of these lesions.

Endovascular treatment of vertebral arteriovenous fistula.
Radiology. 1992 May;183(2):361-7
Authors: Beaujeux RL, Reizine DC, Casasco A, Aymard A, R?fenacht D, Khayata MH, Rich? MC, Merland JJ
The clinical and angiographic features of 46 vertebral arteriovenous fistulas (AVFs) seen during a 12-year period (45 patients) were reviewed. Fourteen patients were asymptomatic, with vertebral AVF discovered at routine clinical examination. Specific symptoms at presentation in the other patients were tinnitus (n = 21), vertigo (n = 6), neurologic deficit (n = 3), and pain (n = 2). Of the 46 AVFs, 19 (41%) were caused by trauma and 27 (59%) were spontaneous. The fistula was found at C-1 to C-2 in 21 (46%) cases, at C-2 to C-5 in five (11%), and below C-5 in 20 (44%). Thirty-four patients (35 vertebral AVFs) were treated with the endovascular technique. Embolization was performed with latex balloons filled with contrast medium in most cases. Endovascular therapy resulted in complete occlusion in 32 cases (91%) and partial occlusion in three (9%). The vertebral artery could not be preserved in three patients. Endovascular balloon treatment of vertebral AVFs is effective in occluding the shunt, avoids general anesthesia and surgical intervention, and results in minimal morbidity. Endovascular therapy is the treatment of choice for vertebral AVF.

A 28 year old woman with systemic lupus erythematosus who developed chronic lupus peritonitis and ascites is described. Lupus peritonitis appeared with abdominal fullness, postprandial abdominal discomfort, and painless ascites. Four months later the patient developed vertigo, headaches, visual disturbances, serositis, and glomerulonephritis. Lupus peritonitis and the other disease manifestations responded to treatment with intravenous pulse methylprednisolone (four 1 g/m2 injections at one week intervals), oral azathioprine (200 mg daily), and diuretics.

Aerotitis, an acute inflammation of the middle ear caused by the difference in air pressure between the airplane cabin and the middle-ear space, is becoming more common in the United States as our society becomes increasingly mobile. We describe a case in which a 33-year-old woman with a resolving upper respiratory tract infection and mildly blocked eustachian tubes flew on a business trip. During ascent, her ears became blocked. This blockage was partially alleviated by a Valsalva's maneuver. On descent, however, her ears became severely blocked, she experienced intense pain, and her tympanic membranes ruptured. She became nauseated and vomited. Her hearing became significantly diminished and she experienced vertigo. On landing, she was taken to a local emergency room and treated with penicillin and antivertiginous medication. Subsequent otologic evaluation revealed severe permanent sensorineural hearing loss. The vestibular symptoms lasted several months. She now requires hearing aids on a permanent basis. Suggestions are presented for prevention and treatment of aerotitis.

Randomized comparative study of 0.5 and 1 g of cefodizime (HR 221) versus 1 g of cefotaxime for acute uncomplicated urogenital gonorrhea.
Antimicrob Agents Chemother. 1988 Apr;32(4):426-9
Authors: van der Willigen AH, Wagenvoort JH, Schalla WO, Knapp JS, Boot JM, Heeres-Weststrate PL, Michel MF, van Klingeren B, Stolz E
Uncomplicated urogenital and concomitant oropharyngeal gonorrhea in 424 male and female patients was treated in a randomized comparative study with 0.5 g of cefodizime (89 men and 54 women), 1 g of cefodizime (87 men and 52 women), or 1 g of cefotaxime (86 men and 56 women). The cure rates were 100% for men and women in the group given 0.5 g of cefodizime, 100% for men and women in the group given 1 g of cefodizime, and 99% for men and 100% for women in the group given 1 g of cefotaxime. The MICs of cefodizime and cefotaxime for the isolate of Neisseria gonorrhoeae ranged from 0.004 to 0.06 micrograms/ml. Chlamydia trachomatis was isolated before treatment in 15% and after treatment in 13% of all patients. Side effects, such as nausea, diarrhea, abdominal pain, genital candidiasis, and pain at the site of injection, developed in 4% of the patients given cefodizime. Side effects, such as vertigo, genital candidiasis, fatigability, and diarrhea, developed in 4% of the patients treated with cefotaxime. In both groups of patients, the side effects were mild and transient. Cefodizime and cefotaxime are safe and effective agents in the treatment of uncomplicated urogenital gonorrhea.

Polyarteritis nodosa and familial Mediterranean fever.
Br J Rheumatol. 1987 Apr;26(2):139-41
Authors: Sachs D, Langevitz P, Morag B, Pras M
A 22-year-old familial Mediterranean fever (FMF) patient was hospitalized for continuous fever, myalgia, hypertension, vertigo and a petechial rash. Laboratory findings revealed hyperglobulinaemia, thrombocytosis and a leukaemoid reaction. While on steroid therapy the patient sustained a haemorrhage into a renal aneurysm which responded to gel foam embolization. After 12 months of follow-up his condition remained stable under treatment with cyclophosphamide, prednisone and antihypertensive medications. This case provides the fourth example of polyarteritis nodosa associated with FMF.

Clinical study evaluating efficacy of praziquantel in clonorchiasis.
Antimicrob Agents Chemother. 1987 Feb;31(2):135-8
Authors: Yangco BG, De Lerma C, Lyman GH, Price DL
In 74 patients with clonorchiasis, the efficacy and safety of praziquantel was evaluated in a two-phase study: a double-blind, randomized controlled trial of praziquantel versus placebo (42 patients) and an open study (32 patients). All but one of the patients were Laotians. The intensity of clonorchiasis was light in 85% (63 of 74) and moderate in 15% (11 of 74) of the patients. Cure based on our established criteria was noted in 67 of 67 patients (100%) treated with praziquantel at a dose of 75 mg/kg per day. In contrast, four patients (20%) in the placebo group, each with light infection, ceased passing eggs and were, according to our established protocol, considered spontaneous cures (P less than 0.0001). Adverse effects of praziquantel were transient and included nausea and vomiting (15%), vertigo (12%), hepatomegaly (4.5%), headache (1.5%), rash (1.5%), and hypotension (1.5%). Of 20 patients who received placebo, 1 (5%) developed transient skin rash, fever, and chills. Clinically minor and transient, but statistically significant, changes in hemoglobin, total protein in serum, and levels of uric acid, cholesterol, and bilirubin in serum were noted. Results of this study showed that praziquantel is safe, well tolerated, and effective and should be considered as the drug of choice for treatment of clonorchiasis. In moderate infections, a second course of praziquantel therapy may be necessary to eliminate infection.

Cholesterol granuloma of the petrous apex: CT diagnosis.
Radiology. 1984 Dec;153(3):705-11
Authors: Lo WW, Solti-Bohman LG, Brackmann DE, Gruskin P
Cholesterol granuloma of the petrous apex is a readily recognizable and treatable entity that is more common than previously realized. Cholesterol granuloma grows slowly in the petrous apex as a mass lesion until it produces hearing loss, tinnitus, vertigo, and facial twitching. Twelve cases of cholesterol granuloma of the petrous apex are illustrated; ten of these are analyzed in detail, especially with respect to CT findings. A sharply and smoothly marginated expansile lesion in the petrous apex, isodense with brain and nonenhancing on CT, is in all probability a cholesterol granuloma. Cholesterol granuloma and cholesteatoma of the petrous apex are different lesions and treated differently. Cholesterol granuloma can be treated simply and effectively by drainage and permanent fistulization. Preoperative recognition by CT is important for planning proper treatment.

Control of essential hypertension with captopril, an angiotensin converting enzyme inhibitor.
Br J Clin Pharmacol. 1981 May;11(5):469-75
Authors: el-Mehairy MM, Shaker A, Ramadan M, Hamza S, Tadros SS
1 Captopril, an orally active angiotensin converting enzyme inhibitor, was compared with hydrochlorothiazide (HCT) in the treatment of mild and moderate essential hypertension. 2 Twenty outpatients received no antihypertensive therapy for 2 weeks, after which they were given placebo for 8 weeks. Since their diastolic blood pressure remained above 100 mm Hg, they were then randomized to receive either captopril (twelve patients) or HCT (eight patients) for a 4-week titration period. If the supine diastolic blood pressure (SDBP) was normalized, (less than or equal to 90 mm Hg) by the end of titration period, the established regimen was continued for an 8-week maintenance period; if not, the alternate drug was added in increasing doses for up to 4 weeks and the combined therapy was maintained for the remaining 4 weeks. 3 After the first 4 weeks of therapy, both groups showed a statistically significant decrease in both systolic and diastolic blood pressure. Normalization of SDBP occurred in 75% of patients treated with captopril alone, and the addition of HCT produced normalization in the remainder. HCT alone resulted in normalization of SDBP in 50% of patients and the blood pressure of the remaining patients was normalized after the addition of captopril. 4 Captopril given orally, either alone or in conjunction with HCT, is an effective agent for the control of mild and moderate essential hypertension. 5 In our series the main side effects encountered were vertigo and dizziness, transient eosinophilia, a rise of BUN and or/a rise of SGPT or SGOT.

Surgical management of chronic occlusive disease of the aortic arch vessels and vertebral arteries.
Can Med Assoc J. 1981 Apr 15;124(8):972-7
Authors: Maggisano R, Provan JL
Occlusive disease of the aortic arch vessels is relatively rare and often missed initially. Of 41 patients treated surgically for this condition over a 10-year period 38 had arteriosclerotic lesions, 2 had symptoms secondary to vasculitis (Takayasu's arteritis) and 1 had a radiation injury to a subclavian artery. In 22 cases the left subclavian artery was involved; the right subclavian and innominate arteries were the next most commonly affected. Only four vertebral stenoses were treated. Most patients presented with a combination of arm and hindbrain ischemia that was shown radiologically to be associated with a subclavian steal syndrome, but in some only isolated arm symptoms or severe vertigo alone was experienced. There was a difference in blood pressure between the arms of at least 20 mm Hg in 88% of the patients. The treatment for 28 patients was creation of a carotid-subclavian bypass, for 6 the placement of a bypass graft from the ascending aorta to the subclavian or carotid artery or both, for a 3 a subclavian endarterectomy and for 4 vertebral angioplasty. There were no operative deaths, and 90% of the grafts were patent 1 to 72 months later. however, only 30 (73%) of the patients were asymptomatic and 9 (22%) had improved.

Clinical and electroencephalographic features and the response to treatment of 30 patients with episodic dizziness due to epilepsy were noted. The symptom consisted of a brief episode of disequilibrium, often with a sensation of rotation, without evident precipitating factors or sequelae. A history of "absences" or other features suggestive of temporal lobe epilepsy was elicited in over half the patients, and seven (almost a quarter) had had one or more generalized seizures before presentation. Electroencephalography showed a posterior temporal lobe focus in all but two patients, and there was a family history of epilepsy in six. Response to treatment with phenytoin or carbamazepine was good in most patients. Epilepsy should be considered in the differential diagnosis of episodic dizziness or vertigo, especially in young people.

Amikacin was used in 77 treatment courses at a dosage of >/=7.5 mg/kg every 8 h, and patients were monitored for ototoxicity by following serial audiograms, serum creatinine, and amikacin blood levels. Patients were leukopenic (58), were infected by gentamicin-resistant organisms (11), or had cystic fibrosis (8). Three patients developed tinnitus, but none had vertigo or nystagmus. Of 55 courses with pre- and post-treatment audiogram, 13 (24%) were associated with development of high-frequency hearing loss, which was usually bilateral. No patient had conversational hearing loss, and audiograms reverted to normal in three patients. Onset of cochlear damage occurred in one patient after therapy was stopped. The group with high-tone hearing loss, in comparison to the group without audiographic changes, received a larger mean total dose (24 versus 9.6 g), were treated for a longer duration (19 versus 9 days), and more frequently had previous aminoglycosides. Fifty-seven percent of patients with a "peak" serum level exceeding 32 mug/ml and 55% of patients with "trough" levels exceeding 10 mug/ml developed cochlear damage. There was no difference between the groups in age, body weight, previous cochlear damage, renal disease before or during therapy, or average daily dose. Both monitoring of blood levels and limiting duration of therapy may prevent amikacin ototoxicity.
