Electrophysiological findings of brainstem auditory evoked potentials in infants with down syndrome: A systematic review and meta-analysis.

Objective: to summarize the evidence on the electrophysiological findings in the auditory brainstem response (ABR) in infants with DS.

Material And Methods: This is a systematic review study, whose protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO CRD42023424139) and conducted in accordance with the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Observational studies were included: cross-sectional and cohort studies that performed ABR evaluation in infants with DS up to two years of age, which had their results compared with normal infants, of the same age group.

Occurrence of changes in the auditory evoked potentials of smokers: systematic review of the literature.

Purpose: To verify the occurrence of abnormal auditory evoked potentials (AEP) tests in adult smokers.

Research Strategies: Systematic review of the literature according to the PRISMA guidelines, to answer the question: "Are there any changes in the AEP results in adult smokers?", PECOS strategy. Research carried out on PubMed, Embase, CINAHL, LIVIVO, Scopus, Web of Science, LILACS and Scielo databases.

Influence of the type of acoustic transducer in pure-tone audiometry.

Purpose: To compare the air-conduction hearing thresholds obtained with different acoustic transducers and verify the users' preferences regarding them.

Methods: This is a cross-sectional, analytical, observational study with 26 participants aged 18 to 30 years, with normal hearing and no history of exposure to high sound pressure levels or complaints of tinnitus at the time of the assessment. We surveyed their medical history and performed meatoscopy, pure-tone threshold audiometry, speech audiometry, and acoustic immittance.

Outcomes of Automated Auditory Evoked Potential Performed in Different Settings and the Factors Associated with Referred Cases.

 For the population with risk factors for hearing loss, the first option to assess the hearing status is the performance of the automated brainstem auditory evoked potential (BAEP) test because of its efficacy in identifying retrocochlear hearing loss.  To verify the outcomes of automated BAEP performed in different settings as well as the factors associated with the prevalence of hearing impairment.  Cross-sectional study conducted from October of 2014 to May of 2015.

The effect of peri-intraventricular hemorrhage on the auditory pathway of infants.

Objective: To verify the effect of peri-intraventricular hemorrhage on the auditory pathway of preterm infants.

Method: It is a non-concurrent cohort study. This study was conducted in a tertiary public.

Transient evoked otoacoustic emissions and auditory brainstem response in infants with perinatal asphyxia.

Objective: The objective of this study was to verify the effects of perinatal asphyxia on different parts of the auditory system.

Methods: This was a non-concurrent cohort study conducted on a fixed population in a tertiary public hospital. Participants included 181 infants born at term who underwent the transient evoked otoacoustic emission test as a part of a neonatal hearing screening program, with a "pass" result in both ears, and by auditory brainstem response testing.

The importance of retesting the hearing screening as an indicator of the real early hearing disorder.

Introduction: Early diagnosis of hearing loss minimizes its impact on child development. We studied factors that influence the effectiveness of screening programs.

Objective: To investigate the relationship between gender, weight at birth, gestational age, risk factors for hearing loss, venue for newborn hearing screening and "pass" and "fail" results in the retest.

[Assessment of levels of otoacoustic emission response in neonates with perinatal asphyxia].

Objective:: To evaluate the effects of perinatal asphyxia on the level of the response to transient otoacoustic emissions in infants.

Methods:: Otoacoustic emissions in 154 neonates were performed: 54 infants who suffered asphyxia at birth, measured by Apgar score and medical diagnosis, and 100 infants without risk were compared. Scores less than 4 in the first minute and/or less than 6 in the fifth minute were considered as "low Apgar".

Oral changes in individuals undergoing hematopoietic stem cell transplantation.

Introduction: Patients undergoing hematopoietic stem cell transplantation receive high doses of chemotherapy and radiotherapy, which cause severe immunosuppression.

Objective: To report an oral disease management protocol before and after hematopoietic stem cell transplantation.

Methods: A prospective study was carried out with 65 patients aged>18 years, with hematological diseases, who were allocated into two groups: A (allogeneic transplant, 34 patients); B (autologous transplant, 31 patients).

Could the type of treatment for chronic kidney disease affect the auditory system?

Introduction: Chronic kidney disease (CKD) is defined as the presence of renal injury that leads to the slow and progressive loss of kidney function.

Aim: To compare audiological tests between patients with CKD receiving different types of treatment.

Material And Method: This was a clinical and experimental study.

Analysis of transient otoacoustic emissions and brainstem evoked auditory potentials in neonates with hyperbilirubinemia.

Unlabelled: Hyperbilirubinemia is toxic to the auditory pathways and to the central nervous system, leaving sequelae such as hearing loss and encephalopathy.

Aim: to assess the hearing of neonates with hyperbilirubinemia, using transient evoked otoacoustic emissions (TOAEs) and brainstem evoked auditory potentials (BEAP). Prospective study.

[The large vestibular aqueduct syndrome: a cause of neurosensory dysacusia].

Background: the large vestibular aqueduct syndrome (LVAS) is characterized by the enlargement of the vestibular aqueduct associated with sensorioneural hearing loss. The level of hearing loss varies and may be fluctuant, progressive or sudden. Vestibular symptoms may be present.

Cognitive P300 potential in subjects with Diabetes Mellitus.

Unlabelled: Diabetes Mellitus may lead to alterations in the eyes, kidneys, cranial nerves, peripheral nerves, ears etc. The cognitive function also seems to be compromised in subjects presented with Diabetes Mellitus, since the cortical and subcortical structures responsible for this function are hindered in some insulin-dependent patients. The cognitive potential P300 has been used as an objective procedure to assess cerebral cognitive functions.
