Prenatal diagnosis of duplication cyst of the pylorus.

The first description of the antenatal appearance of a duplication cyst of the pylorus is presented. Prior to the infant's delivery, the possibility that this intra-abdominal cystic mass represented a choledochal cyst was also strongly considered. The antenatal detection of this cystic mass allowed close neonatal surveillance and timely surgical intervention prior to the onset of serious neonatal complications. The embryogenesis of duplication cysts of the gastrointestinal tract and bronchopulmonary foregut malformations is reviewed. The clinical utility of the prenatal diagnosis of such fetal gastrointestinal anomalies is also discussed.

The effect of vitamin E treatment on the incidence of OKT+4 lymphocytes in the peripheral blood of children with chronic respiratory tract infections.

Children with respiratory tract infections treated for 6 weeks with vitamin E improved their clinical status and normalized the proportion of OKT+4 T lymphocytes and the ratio of OKT+4 to OKT+8 cells in their peripheral blood.

Cholesterol solubility in bile. Evidence that supersaturated bile is frequent in healthy man.

The development and validation of a direct method for measuring maximum cholesterol solubility in bile is described. Application of this method to five large mammalian species, including man, produced a micellar zone significantly smaller than that previously reported. Further studies on in vitro model solutions patterned after bile confirmed this new micellar zone. Thus, direct evidence demonstrates that the micellar zone boundary derived in vitro from model solutions is applicable to human gallbladder bile. Using the present criteria, normal human bile, in contrast to bile from other mammalian species, is commonly supersaturated with cholesterol. A male-female difference in bile composition is not demonstrable despite the well-established female preponderance of cholelithiasis. Bile from patients with cholesterol cholelithiasis has a micellar zone similar to normals but differs compositionally in that there is a greater excess of cholesterol above saturation. We conclude that cholesterol supersaturation may be a necessary but not solely sufficient cause for gallstone formation.
