ABSTRACT

OBJECTIVE: To characterize the prevalence, imaging characteristics, and cochlear implant candidacy of pediatric patients with single-sided deafness (SSD).

METHODS: An audiometric database of patients evaluated at a large tertiary academic medical center was retrospectively queried to identify pediatric patients (<18 years old) with SSD, defined as se vere to profound sensorineural hearing loss in one ear and normal hearing in the other. Medical records of identified patients were reviewed to characterize the prevalence, etiology, and cochlear implant candidacy of pediatric patients with SSD.

RESULTS: We reviewed audiometric data obtained from 1993 to 2018 for 52,878 children at our institution. 191 (0.36%) had the diagnosis of SSD. Cochlear nerve deficiency (either hypoplasia or aplasia) diagnosed on MRI and/or CT was the most common etiology of SSD and was present in 22 of 88 (25%) pediatric SSD patients with available imaging data. 70 of 106 (66%) pediatric SSD patients with available imaging had anatomy amenable to cochlear implantation.

CONCLUSIONS: Pediatric SSD is a rare condition and the most common etiology based on radiology is cochlear nerve deficiency. High resolution imaging of the temporal bone is essential to determine cochlear nerve morphology prior to consideration of cochlear implantation.

ABSTRACT

OBJECTIVES: Tinnitus can be a chronic symptom that brings disability and distress. Some studies suggested that gabapentin might be effective on tinnitus relief. The objective of the study is to perform a systematic review in order to evaluate the efficacy of oral gabapentin in patients with tinnitus.

METHODS: A literature search was conducted in English and following the recommendations from PRISMA. The terms used were: ("tinnitus" OR "subjective tinnitus") AND ("gabapentin"). The study selection was performed following the eligibility criteria in accordance to the PICOS (population, intervention, comparison, outcome, study design) strategy-patients with tinnitus; oral gabapentin; placebo; reduction of tinnitus severity questionnaires scores; prospective, double-blind, randomized controlled trial, respectively. The selected studies were included in qualitative synthesis. The studies were analyzed according to Joanna Briggs Institute's critical appraisal checklist for randomized controlled trials.

RESULTS: One hundred twenty-one studies were found in 9 databases and 8 studies were found in gray literature. After study selection, 6 articles were read in full. Then, 2 studies were excluded and 4 were included in qualitative synthesis. All 4 articles were analyzed according to critical evaluation checklist.

CONCLUSIONS: Th ere is insufficient evidence to recommend the use of gabapentin for patients with tinnitus.

ABSTRACT

The most common cause of cerebrospinal fluid (CSF) rhinorrhoea is damage to the skull base with a dura mater's rupture due to an accident or an iatrogenic injury. This applies to over 96% of cases. Other possibilities that can lead to CSF leakage are neoplasms of the nasal cavity, paranasal sinuses, and nasopharynx. Although prostate cancer spreads to bones, crani al metastases to paranasal sinuses are extremely rare. We present a case of an 83-year-old patient with CSF leakage due to infiltrating metastatic prostate cancer. Cerebrospinal fluid rhinorrhea turned out to be the first symptom of prostate cancer metastasis. Diagnostic and treatment strategies are presented in the discussion.

Angiolymphoid Hyperplasia of the External Auditory Canal; Reconstruction of a Complex Defect

ABSTRACT

Angiolymphoid hyperplasia (AH) was first described by Wells and Whimster in 1969 as a benign vasoproliferative pathology with a varied infiltrate of eosinophils, lymphocytes, and plasmatic cells. Clinical presentation has been described in the literature as small red-bluish nodules, less than 3 cm in diameter that can bleed in 25% of the cases and be pruritic and painful in 37% and 20% of the cases, respectively. Particularly, AH can appear in the ear; nevertheless, other regions have been affected, including the scalp, lips, tongue, orbit, muscle, and bone. Most of these cases have occurred in adults with an unknown etiology; however, an inflammatory process has been associated in approximately 20% with eosinophilia. No malignancy has been reported.

xlomafota13 shared this article with you from Inoreader

Codas. 2021 May 21;33(2):e20190207. doi: 10.1590/2317-1782/20202019207. eCollection 2021.

ABSTRACT

PURPOSE: To identify and analyze what are the characteristic findings of Cortical Auditory Evoked Potentials (CAEP) in children and / or adolescents with Autism Spectrum Disorder (ASD) compared to typical development, through a systematic literature review.

RESEARCH STRATEGIES: Based on the formulation of a research question, a bibliographic survey was carried out in seven databases (Web of Science, Pubmed, Cochrane Library, Lilacs, Scielo, Science Direct, and Google Sholar), with the following descriptors: autism spectrum disorder (transtorno do espectro autista), autistic disorder (transtorno autístico), evoked potentials, auditory (potenciais evocados auditivos), event related potentials, P300 (potencial evocado P300) e child (criança). This review was registered in Prospero, under number 118751.

SELECTION CRITERIA: Were selecte d articles published, without language limitation, between 2007 and 2019.

DATA ANALYSIS: The characteristics of the latency and amplitude aspects of the P1, N1, P2, N2 and P3 components present in the CAEP.

RESULTS: 193 studies were located; however, 15 original articles were included the inclusion criteria for this study. Although it has not been possible to identify any pattern of response for the P1, N1, P2 and N2 components, the results of the selected studies have demonstrated that individuals with ASD may present a decrease in amplitude and increase in latency of the P3 component.

CONCLUSION: Individuals with ASD may present different responses to the components of the CAEP, and the decrease of the amplitude and increase of the latency of the P3 component were the most common characteristics.

Abstract

Foreign Body (FB) aspiration pose a challenge to the otolaryngologist of its early diagnosis along with safe removal. Almost all airway foreign bodies require bronchoscopy and removal. Very rarely, spontaneous expulsion of bronchial FB may happen. We are reporting one such case of spontaneous expulsion of a metallic FB from right main bronchus in a fourteen-year-old boy. The mainstay of treatment for FB bronchus is bronchoscopic removal. Spontaneous expulsion occurs very rarely & may be associated with life threatening complications. Impaction of FB in sub glottis may lead to sudden choking & death. In this report we also have tried to provide insight into the physics and physiological mechanism facilitating spontaneous expulsion of a bronchial foreign body.

Media Commercials Conveying Awareness Regarding Prevention of Head and Neck Cancer by Focusing on Stigmatized Perspective of Disease: Right or Wrong?

Abstract

Cancer in the head and neck region is among the most common cancer around the world, the incidence of which keep increasing in past years. Treatment of disease is usually done by the surgical excision which often leads to some degree of facial disfigurements which cause mutilation in patients. Mutilation imparts the feeling of stigma in patients, and patients usually tend to hide facial disfigurements using additional clothing. As a prevention strategy, awareness regarding the disease conveys to the mass population via media commercials. Media commercials which highlight the adverse outcomes of cancer are found to target the stigmatized perspective of disease. On the brighter side, more stigmatized is the patient image in the commercials, more motivation it will create in masses to avoid risk factors like tobacco, smoking and alcohol. But on the darker side, stigmatized commercials create a social environment in which people tend to maintain social distance to cancer patients, and patients have to bear social disapproval by society for their whole life. It reduces the self-esteem and quality of life of patients which affects their overall survival. In the present article, we review the status of stigma in head and neck cancer patients, tools that are available for a ssessment of stigma, and effects of the stigmatized media commercials on the patient's self-esteem. The present article represents the accurate picture of the problem and highlights the policies which could be employed to balance the paradox of stigmatized media commercials and a healthy social environment for cancer patients.
