Omphalocele-exstrophy-imperforate-anus-spina bifida (OEIS) complex in a male prenatally exposed to diazepam.

A male clinically affected by the OEIS complex was studied. His mother, aged 30 years, has an affective disorder and ingested 30 mg of Diazepam daily, from 3 months previous to the gestation and during the entire pregnancy. At birth, a closure during the entire pregnancy. At birth, a closure defect of the anterior abdominal wall, exstrophy of hemibladders, exposure of intestinal epithelium, abnormal pelvis, imperforate anus, and bifid penis were noted. Birth weight was 3600 g and other measurements were not recorded. Colostomy was performed in the postnatal period followed by partial closure of the abdominal wall defect, and iliac osteotomies. At six years, 6 months of age, physical examination showed somatometric measurements around the third percentile (height 109 cm, weight 17 kg, cephalic circumference 48.5 cm). Clinically he presented mild mental retardation, functional colostomy, incomplete closure of the vesical exstrophy, imperforate anus, bifid penis and scrotum, descended testes, diastasis of pubis, lumbosacral scoliosis and shortening of the left leg (clinical photograph of the external features is not included as we were not able to obtain authorization to do so). Radiological studies (Figure 1) revealed wide separation of the ischiopubic bones; lumbosacral region with rotoscoliosis, platyspondyly and dysraphism; left coxa valga, and right coxa vara. The abdominal ultrasonographic studies showed unilateral renal agenesis (left). Chromosomal analysis (GTG bands) in peripheral blood lymphocyte cultures demonstrated a normal 46,XY constitution. Exposure to other substances, particularly alcohol, were excluded with the study of the mother's medical history and through information obtained from relatives.(ABSTRACT TRUNCATED AT 250 WORDS)
