Auditory Pathway Maturation in Full-term Small for Gestational Age Children: A Systematic Review with Meta-analysis.

 Factors of intrauterine growth restriction have been responsible for the births of full-term babies small for their gestational age (SGA). Scientific evidence points that this restriction can cause changes in the neural maturation process.  To analyze the absolute latencies and interpeak intervals of brainstem auditory evoked potential waves in full-term and SGA children to investigate whether there are changes of neural maturation in this population.

Evidence of changes in the oral language in children born full-term and small for gestational age: a systematic review.

Objective: To perform a systematic review in order to verify the association between full-term birth of small for gestational age (SGA) children and the outcomes in the development of oral language.Data source:Articles from MEDLINE/PubMed, Web of Science, Embase, Lilacs, SciELO and Cochrane Library databases were identified, selected and critically evaluated by two independent reviewers and a judge, blindly, without language restriction and publication period. The PRISMA tool was used, and original studies with a theme involving children born full-term and SGA were included, outcome related to aspects of oral language development, as well as the use of tests, scales and/or specific questionnaires for the investigation, whose methodology was described in full, with children as the target population.

Phonological productive processes in full-term schoolchildren and small for gestational age: a case-control study.

Purpose: To characterize the use of phonological productive processes in a group of full-term children and small for gestational age and compare it with children appropriate for gestational age.

Methods: Observational, analytical, case-control and non-paired study, nested in a cohort with the outcome of phonological disorder. We assessed 36 children according to the predetermined sample calculation, 24 (66.

Dysfunction of the auditory system in sickle cell anaemia: a systematic review with meta-analysis.

Objectives: To describe the occurrence of both peripheral and central auditory system dysfunction in sickle cell anaemia (SCA) patients and discuss the different mechanisms hypothesised to be responsible for these alterations.

Methods: An electronic search was conducted using PubMed Central (MEDLINE), LILACS and Scopus databases. This systematic review was performed in accordance with the PRISMA statement.

Cochlear dysfunction evidenced by reduction of amplitude of otoacoustic responses in patients with congenital hypothyroidism.

Introduction: The investigation of amplitudes of otoacoustic emissions in congenital hypothyroidism can provide information on cochlear function with more sensibility, when compared to other methods of auditory evaluation.

Aim: To investigate cochlear function through the amplitude of distortion product otoacoustic emissions in individuals with congenital hypothyroidism and to correlate with clinical aspects.

Methods: An exploratory, analytical, cross-sectional study with a convenience sample, composed of 50 individuals with congenital hypothyroidism and a group of 42 individuals without the disease, mean age of 8.

CONGENITAL HYPOTHYROIDISM AS A RISK FACTOR FOR CENTRAL HEARING PROCESS DISORDERS.

Objective: To investigate the presence of central auditory processing disorder symptoms in children with congenital hypothyroidism.

Methods: An exploratory, descriptive, cross-sectional study of 112 patients with congenital hypothyroidism aged ≥5 years old. An interview was held with the parents/caregivers at the time of the medical consultation.

Sensorineural hearing loss in children with sickle cell anemia and its association with endothelial dysfunction.

Objectives: To investigate the prevalence of sensorineural hearing loss (SNHL) in children and adolescents with sickle cell anemia (SCA) and its association with endothelial dysfunction (ED).

Methods: Fifty-two participants with stable SCA and 44 apparently healthy (AA genotype) participants aged 6-18 years were evaluated for pure tone audiometry and endothelial function using ultrasonographic imaging of the brachial artery to assess flow-mediated dilation (FMD). Laboratory analysis of the lipid profile and C-reactive protein levels was performed.

Mechanisms involved in hearing disorders of thyroid ontogeny: a literature review.

Endocochlear, retrocochlear and/or central origin hearing damage may be related to the absence of appropriate levels of thyroid hormone during morphogenesis and/or auditory system development. Hearing disorders related to the thyroid are not well studied, despite speculation on the pathophysiological mechanisms. The objective of this review was to characterize the main pathophysiological mechanisms of congenital hypothyroidism and to evaluate the relationship with central and peripheral hearing disorders.

Tinnitus and normal hearing: a study on contralateral acoustic reflex.

Purpose: The aim of this study was to evaluate the difference of the contralateral acoustic reflex (AR) threshold between adult subjects with hearing within clinically normal limits, with and without tinnitus.

Method: The study sample in this exploratory, descriptive, and comparative study comprised 40 female subjects who were evaluated: 20 had tinnitus and 20 formed the control group. The contralateral AR threshold was evaluated at the frequencies of 500, 1000, and 2000 Hz.

Non-syndromic hearing impairment in a multi-ethnic population of Northeastern Brazil.

Objective: There are many hearing impaired individuals in Monte Santo, a rural municipality in the state of Bahia, Brazil, including multiple familial cases strongly suggestive of a genetic aetiology.

Methods: The present study investigated 81 subjects with hearing impairment (HI) recruited from 36 families. Mutations often associated with HI, i.

Tinnitus and normal hearing: a study on the transient otoacoustic emissions suppression.

Unlabelled: The workings of the auditory pathway of patients with tinnitus and normal hearing can be associated with an auditory efferent pathway dysfunction at the level of the superior olivary complex. Otoacoustic emission suppression with contralateral noise can represent an alternative to its evaluation.

Aim: to investigate Transient Otoacoustic Emission suppression in normal hearing adults with and without tinnitus and to compare the two groups.
