Purpose: The pathogenesis of pulmonary hypoplasia associated with congenital diaphragmatic hernia (CDH) remains unclear. Interactions between the epithelium and surrounding mesenchyme play an important role in normal lung morphogenesis. Epimorphin, a stromal protein, plays a role in epithelial morphogenesis and lung branching, both of which are involved in pulmonary hypoplasia.

It is unclear whether massive small bowel resection (SBR) affects prostaglandin E2 synthesis in the gastrointestinal tracts. Thus the aim of this study was to investigate possible changes over tissue levels of prostaglandin E2 in the stomach and ileum after massive proximal SBR. Female Swiss-Albino rats underwent control operation (groups 1, 3, 5) or an 80% SBR (groups 2, 4, 6).

Although the combination of gastric outlet obstruction and esophageal atresia is rarely seen in neonates, it has been well described. We report the case of a 5-day-old newborn with esophageal atresia and tracheoesophageal fistula associated with complete gastric outlet obstruction due to a mucous plug. As the patient had intense gastric distention, severe respiratory distress requiring ventilatory therapy and complete pyloric obstruction in radiograms, emergency gastrostomy was performed before definitive operation.

Patients with multiple pregnancies have an increased risk of preterm labor and delivery with the associated high prenatal morbidity and mortality. Obviously, as the number of multifetal pregnancies increases (due primarily to the use of assisted reproductive treatments), a rise in the unexpected birth of one or more siblings at premature or previable stages is observed. In multiple pregnancies with imminent preterm birth, delayed delivery may offer survival chances and a favorable outcome for the remaining fetus(es).
