Etiology of Deafness in Neonates from a Universal Hearing Screening Program, 2003-2006

A descriptive, cross-sectional study of 17 neonates diagnosed with hearing loss in a universal newborn hearing screening program from August 2003 to December 2006. The research, authored by Tânia Pereira, determined probable etiologies through detailed anamnesis, serological tests, tomography, and genetic tests. Prenatal causes accounted for 64.7% of cases, with 36.4% having a confirmed genetic origin.

Use Cases

• Analyze the distribution of prenatal versus perinatal etiologies of neonatal deafness based on the study's findings.
• Investigate the association between specific congenital infections (e.g., toxoplasmosis, cytomegalovirus) and hearing loss based on the serological testing protocol.
• Study the prevalence of profound hearing loss (47.1% in this cohort) relative to other degrees of loss.
• Model the contribution of genetic factors (36.4% confirmed) to congenital hearing impairment.

Strengths

• The study includes 17 diagnosed cases with a defined temporal scope from 2003 to 2006.
• Etiology was investigated using a multi-method protocol including anamnesis, serology, tomography, and genetic tests.
• Results provide specific percentages for etiology categories (e.g., 64.7% prenatal, 29.4% perinatal) and the degree of hearing loss (47.1% profound).

Limitations

• Row count is unknown, which may limit suitability assessment for statistical modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect temporal and institutional bias inherent to a single study from paperswithcode.
