Hearing Impairment Overview in Africa: the Case of Cameroon.

The incidence of hearing impairment (HI) is higher in low- and middle-income countries when compared to high-income countries. There is therefore a necessity to estimate the burden of this condition in developing world. The aim of our study was to use a systematic approach to provide summarized data on the prevalence, etiologies, clinical patterns and genetics of HI in Cameroon.

and Mutations in Hereditary Recessive Non-Syndromic Hearing Impairment in Cameroon.

This study aimed to investigate (connexin 26) and (connexin 30) mutations associated with familial non-syndromic childhood hearing impairment (HI) in Cameroon. We selected only families segregating HI, with at least two affected individuals and with strong evidence of non-environmental causes. DNA was extracted from peripheral blood, and the entire coding region of was interrogated using Sanger sequencing.

Cochlear implantation in patients with enlarged vestibular aqueduct. A case series with literature review.

Objectives: To report our institutional experience of the management of patients with enlarged vestibular aqueduct (EVA) and compare it to the literature.

Methods: We carried out a retrospective review of patients' records from 1993 to 2015. The age, sex, associated malformations, relevant past medical history, genetic screening results, possible surgical incident, implant model and duration of follow- up, outcome in terms of Categories of Auditory Performance (CAP scores), and integration or resuming mainstream school or work were recorded.

Management of subglottic hemangiomas with carbon dioxide laser: Our 25-year experience and comparison with the literature.

Introduction: Subglottic hemangiomas (SGH) are rare tumors of infancy arising between the perichondrium and the mucosa of the subglottic space. It is a potential life-threatening condition. Many therapeutic options exist for this disease, including lasers.

Effect of HIV Infection and Highly Active Antiretroviral Therapy on Hearing Function: A Prospective Case-Control Study From Cameroon.

Importance: Human immunodeficiency virus (HIV) infection remains a major cause of morbidity and mortality worldwide. Many studies have found a higher prevalence of hearing impairment among HIV-positive individuals.

Objective: To investigate the effect of HIV and highly active antiretroviral treatment (HAART) on the hearing function in a Cameroonian population.
