RESUMO
PURPOSE: To examine the prevalence of adherence to hearing aids and determine their rejection causes. METHODS: This study was conducted according to the Preferred Reporting terms for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We performed an electronic search using PubMed, BVS, and Embase. RESULTS: 21 studies that met the inclusion criteria were selected. They analyzed a total of 12,696 individuals. We observed that the most common causes for positive adherence to hearing aid use included having a higher degree of hearing loss, patients being aware of their condition, and requiring the device in their daily life. The most common causes for rejection were the lack of perceived benefits or discomfort with the use of the device. The results from the meta-analysis show a prevalence of patients who used their hearing aid of 0.623 (95% CI 0.531, 0.714). Both groups are highly heterogeneous (I2 = 99.31% in each group, p < 0.05). CONCLUSIONS: A significant proportion of patients (38%) do not use their hearing aid devices. Homogeneous multicenter studies using the same methodology are needed to analyze the causes of rejection of hearing aids.
RESUMO
BACKGROUND: Horizontal Canal Cupulolithiasis (hc-BPPV-cu) can mimic a pathology of central origin, so a careful examination is essential to prevent misdiagnosis. METHODS: Retrospective cross-sectional cohort study of 45 patients suffering from suspected hc-BPPV-cu. We recorded whether patients first presented through an ENT Emergency Department (ED) or through an Outpatient Otolaryngology Clinic (OC). RESULTS: We found statistically significant differences (p < 0.05) between the OC versus the ED in relation to the time between symptom onset and first assessment (79.7 vs. 3.6 days, respectively), the number of therapeutic maneuvers (one maneuver in 62.5% vs. 75.9%, and more than one in 25.1% vs. 13.7%), and multi-canal BPPV rate (43.8% vs. 3.4%). hc-BPPV-cu did not resolve in 2 patients (12.5%) from the OC and in 3 (10.3%) from de ED, all of which showed central pathology. DISCUSSION: There are no prior studies that analyze the approach to hc-BPPV-cu in the ED. The benefits of early specialist input are early identification of central positional nystagmus, a decrease in symptom duration, reduced number of therapeutic maneuvers required for symptom resolution, and lower rates of iatrogenic multi-canal BPPV. CONCLUSION: A comprehensive approach to hc-BPPV-cu in the ED allows both more effective treatment and early identification of central disorder mimics.

Aneurysms of the jugular vein are an uncommon condition, typical of childhood and adolescence although they can appear at any age. Clinically, they normally constitute an asymptomatic cervical mass which increases when Valsalva's manoeuvre is applied. Doppler echography is the most effective diagnostic test, with CT or NMR for doubtful situations. Treatment is conservative except for complications or major aesthetic repercussions. We present here the case of a 65-year-old female patient, and review the literature regarding aneurysms of the jugular vein.

OBJECTIVE: To describe the stage-related clinical features of 8th cranial nerve schwannoma. MATERIAL AND METHOD: Descriptive study of 71 patients whose diagnosis and/or treatment have been carried out at our centre between 1997-2003. Gender, age, and symptoms were considered, with special attention to gender. Determination of tumoral stage following Tos and Thomsen image criteria. RESULTS: The mean age was 64.6 (range, 20-87) with a marked incidence between 52 and 70 years (62 % of the whole), slightly higher in females and in the left ear. The main symptoms were those derived from involvement of the 7th and 8th cranial nerves, with other cranial nerves and cerebello-pontine structures being involved in larger tumours, although a high variability was noted in clinical patterns of same-stage cases and in the first symptom. Our study also found a high variability in hearing conservation and a marked frequency of vestibular or facial (motor and sensory) symptoms. There were also very infrequent forms of presentation that are highlighted. CONCLUSIONS: There is no typical clinical pattern and no typical first symptom in 8th cranial nerve schwannomas. Any audiovestibular or facial symptom, even the slightest, may be the first expression of 8th cranial nerve schwannoma. There is no stage-specific symptom except for those with involvement of the cerebello-pontine or cerebral structures.
