Prevalência das fissuras labiopalatinas no município de Bauru: concordância de diagnóstico entre registros do HRAC/USP, DNV e SINASC

Abstract

Cleft lip and palate are the most common congenital defects involving the face. Epidemiological studies are important for the delineation of cases and allocation of resources for treatment. Objectives: To determine the prevalence of cleft lip and palate in Bauru by notification in the Declaration of Live Birth (DNV) and Live Birth Information System (SINASC) as compared to records of the Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo (HRAC/USP). Methodology: Retrospective observational study by evaluation of all DNV and identification of individuals with cleft lip and palate born and living in Bauru between 01/01/2000 and 31/12/2010, compared to the registries of HRAC/USP. The prevalence was calculated by dividing the number of children with cleft lip and palate by the total number of live births recorded during the study period. Notification of different types of clefts was compared by the chi-square test. Results: During the study period 50,898 DNV were analyzed, among which there were 232 notifications of congenital anomalies (1:219 livebirths), being 25 of cleft lip and palate (1:2,036 livebirths). In the same period, the HRAC/USP registered 77 cases, revealing a prevalence of 1:661 livebirths, representing 67.5% of subnotification of clefts. Cleft palate was the most prevalent (34.9%), followed by cleft lip and palate (31.7%) and cleft lip (30.2%), predominantly affecting the male gender (58.5%). The notification of cleft palate (16.12%) was smaller compared to cleft lip (43.75%) and cleft lip and palate (54.54%). Conclusion: The study revealed predominance of cleft palate, with significant subnotification of clefts in the public health system, especially for cleft palate as compared to cleft lip and cleft lip and palate. Efforts should be made to achieve trustable and reliable data from the public health system that uses the DNV and the SINASC as data source.

Hipodontia associada a fissura oral não sindrômica pode ter influência na recorrência familial para as fissuras?

“…A prevalência média da FO é de 0,57 a 2,62 indivíduos para cada 1000 nascidos vivos (PANAMONTA et al, 2015). No Brasil, admite-se que essa taxa de FO oscile em torno de 1:661 (VARGAS, 2015). Existe uma variação nesses dados em relação à localização geográfica e condições socioeconômicas (JIA et al, 2009), com uma maior prevalência nos indivíduos de ascendência asiática, seguida pelos caucasianos e negros (MARAZITA et al, 2002).…”
