This study investigated the possible correlation between the degree of hearing impairment caused by neonatal purulent meningitis and the levels of CD64 and PCT in cerebrospinal fluid of patients, and assessed the prognostic value of such levels. We recorded data from 156 cases of neonatal purulent meningitis retrospectively. All the patients received brainstem response audiometry, and cerebrosp...

INTRODUCTION Mutations in GJB2 are the most common cause of non-syndromic autosomal recessive hearing impairment, ranging from mild to profound. Mutation analysis of this gene is widely available as a genetic diagnostic test. OBJECTIVE To assess a possible genotype-phenotype correlation for GJB2. DESIGN Retrospective analysis of audiometric data from people with hearing impairment, segregat...

OBJECTIVES To examine the association between hearing impairment and incident frailty in older adults. DESIGN Cross-sectional and longitudinal analyses with 4-year follow-up using data from the English Longitudinal Study of Ageing. SETTING Community. PARTICIPANTS Community-dwelling individuals aged 60 and older with data on hearing and frailty status (N = 2,836). MEASUREMENTS Hearing im...

OBJECTIVE The objective of this study was to examine the risk factors of low/mid-frequency and high-frequency hearing impairment among a nationally representative sample of diabetic adults. RESEARCH DESIGN AND METHODS Data came from 536 participants, aged 20-69 years, with diagnosed or undiagnosed diabetes who completed audiometric testing during 1999-2004 in the National Health and Nutrition...

CONTEXT Recently, several studies have investigated the relationship between diabetes and hearing impairment, but results were inconsistent. OBJECTIVE Our objective was to compare the prevalence of hearing impairment between diabetic and nondiabetic adults. DATA SOURCES We performed a systematic literature search using MEDLINE (1950 to May 30, 2011) and EMBASE (1974 to May 30, 2011). STUD...

There were significant changes in health and lifestyle throughout the 20th century which may have changed temporal patterns of hearing impairment in adults. In this study, the authors aimed to assess the effect of birth cohort on the prevalence of hearing impairment in an adult population aged 45–94 years, using data collected between 1993 and 2008 from 3 cycles of the Epidemiology of Hearing L...

OBJECTIVE Investigate the prevalence of hearing impairment in newborns hospitalized at the Intensive and Intermediate Care Unit at the Women's Comprehensive Health Center Neonatology Service (UNICAMP) and associated risk factors. METHODS 979 newborn babies were assessed between January 2000 and January 2003, through automated auditory brainstem response (AABR) (ALGO 2e color screener). The re...

OBJECTIVE The role of preexisting sensorineural hearing impairment on the risk for sudden sensorineural hearing loss (SSHL) is still unclear. In this study, we aimed to assess the risk of SSHL in patients with common preexisting sensorineural hearing impairment using population-based data. METHODS A population-based case-control study design was used to analyze claims data between January 200...

Hearing impairment is a major limitation in communication, and it can obstruct psychological development, development of social skills and motor development. Hearing impairment is the third most common contemporary chronic health condition, and it has become a public health problem. The effectiveness of problem solving in everyday life and in emergency situations depends greatly on the amount a...
