Resumo

ANDRADE, Caio Leônidas de et al. Prevalence of otoneurological symptoms in individuals with congenital hypothyroidism: pilot study. Cad. saúde colet. [online]. 2017, vol.25, n.2, pp.144-151. ISSN 1414-462X.  http://dx.doi.org/10.1590/1414-462x201700020106.

Purpose

To investigate the frequency of otoneurological symptoms in children with congenital hypothyroidism and correlate them to the clinical aspects.

Methods

Exploratory study of sectional descriptive character. The sample was composed by parents and/or caregivers of 105 children diagnosed with congenital hypothyroidism and age of 5 years or more. Data collection used a structured questionnaire developed and tested by researchers. Clinical and laboratory data were obtained from medical records.

Results

Most subjects (72.4%) showed symptoms related to vestibulocochlear disorder, in which dizziness/vertigo corresponded to 56.2% of symptoms, followed by hearing loss (43.8%) and tinnitus (12.4%). We observed statistical correlation between hearing loss (p = 0.016) and age of neonatal screening test, as well as symptoms of dizziness/vertigo with congenital hypothyroidism (p = 0.003). For hearing loss (PR = 0.49; CI = 0.31 to 0.77), the exposure factor showed a correlation with the probability of 95%.

Conclusion

These findings suggest a significant prevalence and association between congenital hypothyroidism and otoneurological symptoms, especially dizziness, hearing loss and tinnitus.
