IDENTIFICATION OF MOST COMMON CONGENITAL ABNORMALITY TYPES AMONG NEWBORN INFANTS: A HOSPITAL-BASED STUDY
The term “congenital abnormalities” signifies a disruption in the normal process of organogenesis occurring before birth: the earlier the insult, the grosser the abnormality. This research is the largest study aimed at identifying the most common congenital abnormality types among newborn infants in the neonatal care unit (NCU) of the Al-Kadhymia teaching hospital, Baghdad, Iraq. This prospective study was carried out during the period from February 1 to August 1, 2011. A total of 2700 neonates were admitted to the NCU, and 100 newborn infants in the nursery care unit were proven to have congenital abnormalities by physical examination alone. The questionnaire for neonatal evaluation included: gestational age, sex, body weight, and type of congenital anomaly. The results showed that of the total (100) affected neonates, 63 (63%) were full term, 55% had neurological abnormalities, followed by 12% with cleft lip and palate and then 11% with chromosomal abnormalities (most of them had Down syndrome, only 3 cases had Edward syndrome, and 1 case had Patau syndrome). It can be concluded that most of the affected newborns were full term, with a slight male predominance. The incidence of neurological abnormalities was higher than other types of birth defects.
