ABSTRACT
BACKGROUND: Bacterial Translocation is believed to be an important factor on mortality and morbidity in Obstructive Jaundiced. AIMS: We investigated the probable or estimated positive effects of tauroursodeoxycholic acid, which has antibacterial and regulatory effects on intestinal flora, together with glutamine on BT in an experimental obstructive jaundiced rat model. STUDY DESIGN: Animal experimentation. METHODS: Forty adult, male, Sprague Dawley rats were used in this study. Animals were randomised and divided into five groups of eight each: sham (Sh); control (common bile duct ligation, CBDL); and supplementation groups administered tauroursodeoxycholic acid (CBDL+T), glutamine (CBDL+G), or tauroursodeoxycholic acid plus glutamine (CBDL+TG). Blood and liver, spleen, MLN, and ileal samples were taken via laparotomy under sterile conditions for investigation of bacterial translocation and intestinal mucosal integrity and hepatic function tests on the tenth postoperative day. RESULTS: There were statistically significant differences in BT rates in all samples except the spleen of the CBDL+TG group compared with the CBDL group (p=0.041, p=0.026, and p=0.041, respectively). CONCLUSION: It is essential to protect hepatic functions besides maintaining intestinal mucosal integrity in the active struggle against BT occurring in obstructive jaundice. The positive effect on intestinal mucosal integrity can be increased if glutamine is used with tauroursodeoxycholic acid, which also has hepatoprotective and immunomodulatory features.
ABSTRACT
INTRODUCTION: Rett syndrome is a neurologically disorder that affects approximately one in 10,000 females. CASE REPORT: A 21-year-old girl with Rett syndrome was hospitalized for abdominal distention and pain. Physical examination revealed abdominal tenderness. Radiology investigation revealed bilateral free air in subdiaphragmatic area. Gastric perforation observed at laparotomy. Primary suturing and omentoplasty were performed. In the follow-up, the symptoms of intestinal obstruction occurred. Conservative treatment failed and second intervention was performed. At laparotomy severe gastric and intestinal dilatation and bowel adhesions were detected. Adhesiolysis, tube gastrostomy, and feeding jejunostomy performed. DISCUSSION: Rett syndrome and associated gastric complications are uncommon. These pathologic disorders may cause gastric, intestinal necrosis, intestinal obstructions. Because of the late occurring of physical findings and insidious presentation of the gastrointestinal perforations in Rett syndrome, physicians should keep in mind this rare entity to reduce morbidity and mortality.

BACKGROUND: Hydatid disease is a worldwide health problem. Treatment is surgical or percutaneous, using scolicidal agents. Caustic sclerosing cholangitis might develop after the contact of scolicidal agents with the biliary ducts. Melatonin, an antioxidant, anti-inflammatory, and anticarcinogenic agent, might be used in the treatment of caustic sclerosing cholangitis due to its possible preventive effects on fibrosis and cell damage. OBJECTIVE: The aim of the study was to investigate the effects of melatonin on an experimentally developed caustic sclerosing cholangitis with scolicidal solution (formalin) in a rat model. METHODS: Forty female Sprague-Dawley rats aged 11 to 13 weeks and weighing 250 ± 30 g were randomly assigned to 1 of 4 groups of 10: formalin 5% at 0.5 mL/d + melatonin placebo; formalin placebo + intraperitoneal melatonin 10 mg/kg/d; formalin 5% at 0.5 mL/d + melatonin 10 mg/kg/d; and formalin placebo and melatonin placebo (control). Hepatobiliary function was assessed using dynamic scintigraphy with technetium-99m-mebrofenin on study day 60. The histology of the liver and biliary duct specimens was examined on study day 60. In each group, histopathologic alterations were scored as absent, slight, mild, or severe. RESULTS: Mean severity scores for parenchymal necrosis in the liver (P < 0.01), portal fibrosis (P < 0.01), biliary duct proliferation (P < 0.001), cholangitis/ pericholangitis (P < 0.01), hyperemia in the biliary ducts (P < 0.01), and fibrosis (P < 0.01) were significantly lower in rats treated with formalin + melatonin compared with those treated with formalin alone. No significant differences were observed between the 3 treatment groups with respect to t½, a parameter used to assess the secretion function of the hepatocytes. However, the t½ was significantly longer in the treatment groups compared with controls (P < 0.001). CONCLUSION: In this experimental study in a rat model of caustic sclerosing cholangitis, the histopathologic and scintigraphic findings suggested that melatonin is effective in attenuating the damage caused by scolicidal agents on the liver and biliary ducts.
