    Notes: Abstract This paper describes a transumbilical resection and umbilical plasty for treatment of a patent omphalomesenteric duct (POMD). In a newborn infant with a POMD, a skin incision was made circumscribing the mucocutaneous junction of the protruded duct. The duct was completely extirpated with a wedge resection of the connection to the intestine and an umbilical plasty was performed. The postoperative appearance was excellent. It appears that transumbilical resection and umbilical plasty may be a satisfactory operation for POMD.

    Notes: Abstract This article describes a prenatal ultrasonographic finding of an infarcted intestinal volvulus. Ultrasonography showed polyhydramnios, multiple dilated intestinal loops, increased transverse abdominal area, and ascites. After cesarean section due to premature rupture of membranes and fetal distress, derotation of the infarcted volvulus caused postoperative thrombocytopenia, hyperkalemia, and acidosis and a subsequent resection was required. A high output of intestinal juice from the jejunostomy caused severe hypovolemia and electrolyte imbalance with resultant death. Increased transverse abdominal area caused by marked intestinal dilatation, ascites, fetal distress, and hydrops fetalis may suggest an infarcted intestinal volvulus.

    Notes: Abstract This paper describes a rare case of biliary atresia (BA) in which massive postoperative bleeding developed due to portal hypertensive enteropathy. A 15-year-old boy had been doing well after Kasai's operation for BA. At around the age of 6 years he developed recurrent episodes of esophageal variceal bleeding and underwent esophageal transection, splenectomy, sclerotherapy, and embolization of the left gastric vein. At the age of 15 years he suddenly developed abdominal pain, hematemesis, and massive tarry stools. His hemoglobin level was 6.3 g/dl. Endoscopy showed several small, polypoid lesions in the jejunum beyond Treitz' ligament. The source of the bleeding was one of these lesions located in the proximal jejunojejunostomy of the Roux-en-Y loop. Because he had repeated episodes of melena, he underwent partial resection of the jejunum under endoscopic guidance. He has since been free of gastrointestinal (GI) bleeding. From this experience, we conclude that the polypoid lesions of an enteropathy may be a cause of massive GI bleeding in the postoperative portal hypertension of BA.

    Notes: Abstract This paper reports a premature infant with a congenital diaphragmatic hernia (CDH) who underwent an abdominal wall plasty to enlarge the abdominal cavity, one of twin infants born at 32 weeks weighing 1,255 g. After stabilization, the herniated viscera were reduced from the pleural cavity and the abdominal wall muscle and skin layers were replaced by a Gore-tex patch without closure of the diaphragmatic defect. Respiratory and circulatory conditions were stable during the perioperative period. Postoperatively, a roentogenogram showed expansion of the lung. However, his condition deteriorated 24 h after surgery, triggered by intratracheal suction, and he died on the 4th day of life despite the use of high-frequency oscillation, catecholamines, and vasodilators. Postmortem examination showed severely hypoplastic lungs. Abdominal wall plasty may be a less invasive initial procedure, however, further studies, such as comparison with the standard method or conservative management, are needed using a large clinical group or animal models to justify the usefulness of this procedure.

    Notes: Abstract The copolyester of 3-hydroxybutyrate and 3- hydroxyvalerate was synthesized from the combined carbon sources of glucose and sodium propionate by a filamentaion-defective mutant of Sphaerotilus natans, which is a typical filamentous bacterium often found in activated sludge. The 3-hydroxyvalerate content in the produced polymer increased with increasing concentrations of propionate. Cell growth and polyester synthesis were observed even when 0.6% sodium propionate was added to the medium, when the 3-hydroxyvalerate content in the polymer produced was about 60 mol%. The monomer composition of the copolymer was also varied by aeration conditions, time of propionate feeding, and cultivation time. This strain flocculated in accordance with cell growth, allowing rapid and convenient separation of the biomass from the culture fluid.
