A case of ischemic jejunal stricture after surgical reduction of intussusception.

A 15-year-old girl presented with small bowel obstruction due to ischemic jejunal stricture which developed three weeks after successful surgical reduction of an intussusception with a Peutz-Jeghers-type polyp as a lead point. The reduced jejunum had no macroscopic injury, and the stricture caused complete obstruction requiring jejunal resection.

Surgical intervention for emphysematous pulmonary regions in a postoperative infant with congenital diaphragmatic hernia.

A postoperative infant with congenital diaphragmatic hernia (CDH) developed extrinsic obstruction of the trachea by the innominate artery that ensued from unequal expansion of the lungs followed by left mediastinal shift. Septation of the anterior mediastinum prevented unequal expansion of the lungs, and elongation of the innominate artery improved proximal airway obstruction. Prolonged artificial ventilation, however, resulted in the emphysematous bullae in the left lung. Lung volume reduction surgery (LVRS), at 3 years of age, ameliorated the respiratory distress and resulted in good weight gain. Surgical intervention, including LVRS, should be considered to improve respiratory disturbance caused by difference in compliance of the lungs in children.

Measurement of serum hyaluronic acid as a sensitive marker of liver fibrosis in biliary atresia.

PURPOSE: The aim of this study was to clarify whether serum hyaluronic acid level (SHA) can reflect the degree of liver fibrosis in biliary atresia (BA). METHODS: SHA was measured in 44 postoperative BA patients at 7 months to 22 years of age, with sandwich enzyme method (Hy-A 100 kit). SHA was compared with T.Bil (group 1, T Bil < 2; group 2, 2 < or = T Bil < 5; group 3, T Bil > or = 5 mg/dL), fibrosis score (0-6, the number of abnormal values among Alb, PT, ChE, T Chol, Fischer's ratio, prealbumin), and histologic grading (0-IV). RESULTS: SHA was 499.8 +/- 332.5 in group 3, significantly higher than in the control, group 1, or group 2. As fibrosis score rose, SHA became higher, and SHA in Score 6 (430.1 +/- 366.1 ng/mL) and score-5 (172.9 +/- 141.8 ng/mL) was significantly higher than in the control and other scores, respectively. As the histologic grade rose, SHA became higher, and SHA in grade IV (444.8 +/- 323.5 ng/mL) and grade III (166.0 +/- 70.3 ng/mL) was significantly higher than in the control or other Grades. Serial change of SHA since before HPE was parallel to the clinical course in 8 patients. CONCLUSION: SHA may be a useful serum marker reflecting the degree of liver fibrosis in BA.

Total parenteral nutrition-associated intrahepatic cholestasis in infants: 25 years' experience.

BACKGROUND/PURPOSE: There are few long-term chronological reviews examining the incidence of total parenteral nutrition (TPN)-associated intrahepatic cholestasis (TPNAC) in infants. The authors therefore reviewed TPNAC in their 25-year series, and also looked at the current problems associated with TPN in infants. METHODS: Two hundred seventy-three surgical neonates who received TPN for more than 2 weeks were divided into 3 groups chronologically: group A (1971 through 1982, n = 77), group B (1983 through 1987, n = 72), and group C (1992 through 1996, n = 124). TPNAC was defined as serum direct bilirubin (DB) level greater than 2.0 mg/dL during the neonatal period. RESULTS: The incidence of TPNAC in groups A, B and C was 57%, 31%, and 25% (P< .01), respectively, and the mortality rate from TPN-associated complications was 13%, 3%, and 3% (P< .05), respectively. Over the last 5 years, severe TPNAC developed in 20 patients (16%). Four of 20 died of TPN-associated sepsis with hepatic failure; 2 had hypoganglionosis with intractable stagnant enteritis and subsequent sepsis, and 2 had fatal respiratory or cardiac disease. CONCLUSIONS: The incidence of TPNAC in surgical neonates and TPN-associated mortality rates have decreased significantly. The mortality rate, however, still remains at 3%. Two of 4 fatal cases had hypoganglionosis, which were totally dependent on TPN. In patients who require long-term TPN, TPN still has unsolved problems, and small bowel transplantation may be indicated.

Congenital ileal atresia presenting as a single cyst-like lesion on prenatal sonography.

A routine prenatal sonographic examination at 37 weeks' menstrual age revealed a large sonolucent lesion with peristaltic movement in the abdomen of a fetus. After birth, the female infant showed progressive abdominal distention, and radiography showed a bubble-like dilatation of the small intestine. Exploratory laparotomy revealed ileal atresia with nearby partial torsion of the dilated small bowel. The incomplete torsion may have functioned as a check valve, inducing segmental dilatation of the ileum without proximal dilatation.

Effectiveness of acidic oxidative potential water in preventing bacterial infection in islet transplantation.

At a number of points in the current procedures of islet isolation and islet culture after the harvesting of donor pancreata, microorganisms could potentially infect the islet preparation. Furthermore, the use of islets from multiple donors can compound the risks of contamination of individual recipients. Acidic oxidative potential water (also termed electrolyzed strong acid solution, function water, or acqua oxidation water), which was developed in Japan, is a strong acid formed on the anode in the electrolysis of water containing a small amount of sodium chloride. It has these physical properties: pH, from 2.3 to 2.7; oxidative-reduction potential, from 1,000 to 1,100 mV; dissolved chlorine, from 30 to 40 ppm; and dissolved oxygen, from 10 to 30 ppm. Because of these properties, acidic oxidative potential water has strong bactericidal effects on all bacteria including methicillin-resistant Staphylococcus aureus (MRSA), viruses including HIV, HBV, HCV, CMV, and fungi as a result of the action of the active oxygen and active chlorine that it contains. We conducted this study to evaluate the effect of acidic oxidative potential water irrigation on bacterial contamination on the harvesting of porcine pancreata from slaughterhouses for islet xenotransplantation by counting the number of pancreatic surface bacteria using the Dip-slide method, and on the results of islet culture; and to evaluate the direct effect on isolated islets when it is used to prevent bacterial contamination by the static incubation test and by morphological examination. Direct irrigation of the pancreas by acidic oxidative potential water was found to be very effective in preventing bacterial contamination, but direct irrigation of isolated islets slightly decreased their viability and function.

Handlebar hernia: case report and review of pediatric cases.

The authors describe a rare case of handlebar hernia in a 9-year-old-boy. All layers of his abdominal wall were disrupted by a fall on a bicycle; however, his skin and intra-abdominal organs were completely intact. Computed tomography demonstrated subcutaneous intestinal loops protruding through the rent. Surgical repair was performed, and his postoperative course was uneventful.

Subcapsular hemorrhage of the liver in a very-low-birth-weight neonate: survival after decompression laparotomy.

Subcapsular hemorrhage of the liver in a very-low-birth-weight neonate was successfully treated by decompression laparotomy. This may be the second smallest survivor after surgery in the literature.

An unusual presentation of congenital infantile myofibromatosis arising from the interspinous ligament.

The authors describe an extremely rare presentation of congenital infantile myofibromatosis. A full-term newborn boy presented with a thumb-sized subcutaneous mass on the mid-spinal line between the 2nd and 3rd lumbar spinous processes. A solid tumor arising from the interspinous ligament was resected. Microscopic and immunohistochemical studies revealed myofibromatosis.

[Home parenteral nutrition for terminal cancer patients--when should we tell the truth about their disease and return them to their home with HPN].

Home parenteral nutrition (HPN) is a significant way to enable terminally ill cancer patients to live with high quality of life at home. However, the most important condition to perform HPN is the patients' desire to return to their home. For this purpose, we should consider in informing them of the truth of their disease. We had three terminal cancer patients who returned to their home with HPN. Cas 1: 52-year-old woman, recurrent stomach cancer. She did not know her cancer. She stayed at home for 45 days with HPN. Case 2: 46-year-old woman, recurrent stomach cancer. She did not know her recurrence of cancer. She stayed at home for only 15 days with HPN. Case 3: 45-year-old woman, recurrent pancreatic head cancer. She knew her disease and her life expectancy. She had 6-year-old daughter and desired to return home. She stayed at home with HPN for 8 months. As we told Case 3 truth of her disease when she was diagnosed as recurrence of cancer, she lived at home with HPN for 8 months. From the experience of three cases, we may concluded that, the sooner the patients are informed the truth about their disease, the longer they can stay at home with HPN and spend their limited time with high QOL.

[Experience with the Groshong port in a home TPN patient--a case report].

We experienced a home TPN patient using Groshong port. A 45-year-old woman, recurrent pancreatic head cancer, was treated with home TPN. The Groshong port was inserted via external jugular vein and stayed at home for 8 months with home TPN. Lipid emulsion was administered twice a week. After administration of lipid emulsion, 20 ml of saline was injected and catheter lock was performed with only saline. Heparin was not used for catheter lock. After 8 months' home TPN, patient died. We could not find any precipitate in the catheter and reservoir. A unique feature of Groshong port is a pressure-sensitive two-way valve at the intravascular end. The valve of this port opens outward during fluid infusion or bolus injection. During blood withdrawal, the valve opens inward and then closed after the procedure. Because the valve is designed to remain closed between -7 and 80 mmHg, it will not open spontaneously under normal central venous pressure conditions. This valve eliminates the need for heparin flusing. Catheter obstruction during prolonged TPN is a serious complication. Compound of heparin, lipid emulsion and electrolytes, especially calcium is now becoming one of the most important causes of catheter obstruction and catheter removal. We used the Groshong port to prevent catheter obstruction. After 8 months' use of this port, no precipitate was found in this port. We conclude that the Groshong port is useful for home TPN catheter because it can prevent catheter obstruction due to heparin-lipid-electrolytes compound.

Platelet glutathione peroxidase activity in long-term total parenteral nutrition with and without selenium supplementation.

Selenium (Se) is not routinely included in total parenteral nutrition (TPN) solution; thus, patients receiving long-term TPN may be at risk of Se deficiency, which may cause fatal cardiomyopathy. Platelet glutathione peroxidase (GSH-Px) activity, as well as Se levels and GSH-Px activity in plasma and erythrocytes during prolonged TPN, was measured in six patients with chronic gastrointestinal disease. During the time course of TPN, Se administration was discontinued for 12 weeks, and then resupplemented for another 12 weeks. Before the study period, all Se indices had been maintained within the normal range. After discontinuation of Se supplementation, a significant decrease in platelet GSH-Px activity was observed after 1 week (from 64 +/- 7 [mean +/- SD] to 39 +/- 5 U/g of protein). After resupplementation, it increased after 1 week (from 44 +/- 9 to 65 +/- 10 U/g of protein). Plasma Se indices significantly changed within 3 weeks after withdrawal and reintroduction of Se (Se: from 136 +/- 28 to 75 +/- 14 and from 61 +/- 22 to 125 +/- 33 micrograms/L; GSH-Px: from 236 +/- 50 to 140 +/- 36 and from 128 +/- 32 to 220 +/- 64 U/L). Erythrocyte Se indices showed no significant changes during the study period. The results demonstrate that platelet GSH-Px activity is the most sensitive index of Se status in TPN patients.
