This paper presents diagnostic criteria for Menière's disease jointly formulated by the Classification Committee of the Bárány Society, The Japan Society for Equilibrium Research, the European Academy of Otology and Neurotology (EAONO), the Equilibrium Committee of the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) and the Korean Balance Society. The classification includes two categories: definite Menière's disease and probable Menière's disease. The diagnosis of definite Menière's disease is based on clinical criteria and requires the observation of an episodic vertigo syndrome associated with low- to medium-frequency sensorineural hearing loss and fluctuating aural symptoms (hearing, tinnitus and/or fullness) in the affected ear. Duration of vertigo episodes is limited to a period between 20 minutes and 12 hours. Probable Menière's disease is a broader concept defined by episodic vestibular symptoms (vertigo or dizziness) associated with fluctuating aural symptoms occurring in a period from 20 minutes to 24 hours.

Cummings Otolaryngology: Head and Neck Surgery

Background Adverse drug reactions (ADRs) present a challenging and expensive public health problem. Polypharmacy is defined according to the WHO criteria as the, “concurrent use of five or more different prescription medication”. Elderly are more prone to adverse reactions due to comorbid conditions, longer lists of medications and sensitivity to drug effects. The aim of the study is to estimate the incidence and strength of association of ADRs due to polypharmacy among the geriatric cohort attending outpatient clinics at a tertiary care center. Methods A hospital based prospective cohort study was conducted at ambulatory care clinics of Aga Khan University Hospital April 2012 to March 2013. One thousand geriatrics patients (age ≥65 years) visiting ambulatory clinics were identified. They were divided on the basis of exposure (polypharmacy vs. no polypharmacy). We followed them from the time of their enrollment (day zero) to six weeks, checking up on them once a week. Incidence was calculated and Cox Proportional Hazard Model estimates were used. Results The final analysis was performed on 1000 elderly patients. The occurrence of polypharmacy was 70% and the incidence of ADRs was 10.5% among the study cohort. The majority (30%) of patients were unable to read or write. The use of herbal medicine was reported by 3.2% of the patients and homeopathic by 3%. Our Cox adjusted model shows that polypharmacy was 2.3 times more associated with ADRs, con-current complementary and alternative medicine (CAM) was 7.4 times and those who cannot read and write were 1.5 times more associated with ADRs. Conclusion The incidence of ADRs due to poly pharmacy is alarmingly high. The factors associated with ADRs are modifiable. Policies are needed to design and strengthen the prescription pattern.

Hearing Dysfunction After Treatment with Teprotumumab for Thyroid Eye Disease.

OBJECTIVES\nTo determine the long-term efficacy and patient satisfaction of posterior semicircular canal occlusion (PSCO) as a treatment for intractable benign paroxysmal positional vertigo (BPPV).\n\n\nSTUDY DESIGN AND SETTING\nRetrospective analysis of patients with BPPV who underwent PSCO was conducted in a tertiary referral center. Demographic data, clinical records, and audiometric data were reviewed. Dix-Hallpike maneuver, dizziness handicap inventory (DHI), and a specific PSCO questionnaire (PCOQ) were used to measure outcome.\n\n\nRESULTS\nTwenty-eight patients underwent PSCO. The mean follow-up time was 40 months. All patients had normalization of the Hallpike test. DHI scores of 20 patients were recorded. The mean preoperative score was 70 compared with postoperative mean of 13 (P < 0.001). Mild hearing loss was found in 1 patient.\n\n\nCONCLUSIONS AND SIGNIFICANCE\nPSCO is highly successful. The DHI scores postoperatively show significant improvement. The PCOQ revealed an overall 85% patient satisfaction rate. PSCO is a safe and effective intervention for intractable BPPV with a high patient satisfaction rate.\n\n\nEBM RATING\nC-4.

Posterior Semicircular Canal Occlusion and Application of the Dizziness Handicap Inventory

Objective In an era of increasing polypharmacy, adverse drug effects such as ototoxicity have significant public health implications. Despite the availability of evidence, many health care professionals may not know the risk of ototoxicity in common medications. Therefore, the aim of this review is to provide a comprehensive, easy to use, ototoxic profile of medications with an assessment of supporting evidence. Methods Medications of interest were identified through adverse drug reaction reports derived from Micromedex (IBM), Lexicomp (Wolters Kluwer), and the textbook, Drug Induced Diseases: Prevention, Detection, and Management. Additional evidence was identified though a query of PubMed and the Cochrane database. Evidence of causality was graded according to the following: A (randomized, controlled clinical trials), B (nonrandomized clinical trials, prospective observational studies, cohort studies, retrospective studies, case-controlled studies, and/or postmarketing surveillance studies), and C (case reports/case series). Results A total of 194 systemically administered medications associated with ototoxicity were identified, most commonly antimicrobials (53), psychotropics (21), antihypertensive/antiarrhythmics (19), nonsteroidal antiinflammatory drugs (18), and antineoplastics (16). There was evidence of cochleotoxicity in 165 medications (evidence grading A [22], B [77], C [69]), vestibulotoxicity in 100 medications (evidence grading A [23], B [47], and C [30]), and dizziness in 142 medications (evidence grading A [50], B [76], and C [16]). In addition, a review of the evidence of ototoxicity in ototopical medications is also reviewed. Conclusion The effect and severity of ototoxicity can vary immensely depending on pharmacological and individual patient risk factors. The intent of this comprehensive review was to help health care providers of all sectors obtain a deeper knowledge of drug-induced ototoxicity to make more informed management decisions for their patients.

Drug-Induced Ototoxicity: A Comprehensive Review and Reference Guide.

OBJECTIVE Characterize the relationship between cognitive dysfunction and the dizziness severity in Meniere's disease (MD) patients. STUDY DESIGN Retrospective review. SETTING University-based tertiary medical center. PATIENTS Three hundred patients were evaluated for MD from 2015 to 2019. Excluding comorbid or alternative vestibular disorders, 29 patients with definite MD and available pre- and postintervention data were included for analysis. INTERVENTIONS A progressive protocol of salt restriction, diuretics, steroid and/or gentamycin injection, and endolymphatic sac decompression for those refractory to medical therapy. MAIN OUTCOME MEASURES Quality of life measured with the Dizziness Handicap Inventory (DHI) and cognitive function measured with the Cognitive Failures Questionnaire (CFQ). Pre- and posttreatment DHI and DHI subscale scores and change in these scores were correlated with pre- and posttreatment CFQ scores and change in CFQ with therapy. RESULTS Analysis showed a number of limited associations between improvement in DHI and improvement in CFQ. Total DHI scores failed to correlate scores or variation in scores with change in CFQ (p = 0.091 and p = 0.085, respectively). Improvement in the CFQ false-triggering domain was significantly associated with improvement in the DHI physical subscale (r = 0.491, p = 0.007) and was nonsignificantly associated with improvement in total DHI and DHI emotional subscale scores (r = 0.422, p = 0.016 and r = 0.399, p = 0.032). CONCLUSIONS The DHI correlates with several pre- and posttreatment measures of cognitive dysfunction (CFQ) in MD patients. However, change in DHI and CFQ with therapy correlate poorly. Overall, the commonly used DHI may fail to adequately assess cognitive dysfunction in MD patients possibly due to factors not directly implicated by measures of vestibular dysfunction, such as central nervous system or cognitive dysfunction; however, the specific physical and emotional subscales may offer helpful insight into cognitive dysfunction change/improvement with treatment.

OBJECTIVE To examine and improve patient satisfaction with otologic surgery postoperative instructions. STUDY DESIGN Patients undergoing outpatient otologic surgery were compared over two different time periods, before (phase 1) and after (phase 2) modifying postoperative instructions. Key-informant interviews were conducted by phone on postoperative day 7. All patient-initiated communications after surgery were documented. SETTING Tertiary, academic hospital. PATIENTS Patients undergoing outpatient otologic surgery. INTERVENTIONS Otologic surgery. MAIN OUTCOME MEASURES Satisfaction ratings of different postoperative instruction categories (1-10, completely useless to perfectly helpful), including wound care, pain medication, non-pain medication, showering and bathing, activity restrictions, diet restrictions, follow-up appointment, and contact for questions; comments/critiques from patients; and patient-initiated communications. RESULTS Seventy eight patients were included in phase 1 and 52 in phase 2. Patient characteristics and distribution of surgeries were similar between phases. Rating for instructions were high in both phases (phase 1: 8.98[1.50], phase 2: 9.27[1.04], d = 0.216 [-0.271, 0.698]). More patients in phase 2 thought the instructions were adequate and clear (80.0% versus 55.6% in phase 1, d = 0.641 [0.011, 1.271]), and there were fewer critiques per patient (0.09 versus 0.15, d = -0.537 [-1.034, -0.040]) compared with phase 1. There was a shift in phase 2 communications away from wound care questions (17.5% versus 38.9%, d = -0.606 [-1.112, -0.099]) toward questions regarding medications (27.5% versus 6.7%, d = 0.921 [0.325, 1.516]). CONCLUSION An evidence-based postoperative instructions template led to more patients believing that the instructions were clear, fewer critiques being given, and a shift toward more actionable questions rather than those with answers already addressed in written instructions.
