The Prevalence of minor congenital anomalies and normal variations in neonates in Bushehr Port

Abstract

Background: Congenital malformations are a major reason for medical interventions, long-term illness and death. Minor congenital anomaly is not important in appearance and surgical views, and its prevalence in general population is less than 4%, however a normal variation has a prevalence of more than 4% in general population. Methods: In a prospective study from Aug 2002 to Mar 2003, seven hundreds and fifteen (45.45% male and 59.54% female) consecutive newborns in random days were examined for the presence of minor congenital malformations in a university hospital. Results: The overall incidence of minor malformations was 5.03% (55.55% male and 44.46% female p>0.05). 0.28% of neonates had two minor anomalies. The musculoskeletal system (2.25%) was the most common involved system followed by genitourinary system (1.39%), skin (0.99%), ear (0.42%) and nose (0.14%). Mongolian spot (6.01%) and hydrocele (7.69%) were detected as normal variations. The positional clubfoot (1.82%) was the most common minor congenital anomaly followed by undescended tests (1.85% in males) and granular hypospadias (0.92% in males) and sacral dimpling (0.56%). Conclusion: The minor anomalies are detecting in a significant number of neonates in Bushehr Port. Mongolian spot and hydrocele are two normal variations among neonates in Bushehr port
