OBJECTIVE--To determine the prevalence of behaviour disorders in low birthweight infants. DESIGN--Children of birth weight < or = 2000 g born to mothers resident in Merseyside in 1980-1 assessed using the Rutter parent and teacher behaviour questionnaires and the Conner modification of the Rutter teacher questionnaire. Children attending normal schools were assessed with controls matched for age, sex, and class in school. Children attending special schools were assessed unmatched. SUBJECTS--233 matched case-control pairs attending normal primary schools and 46 unmatched children attending special schools. SETTING--Primary and special schools. MAIN OUTCOME MEASURES--Emotional, conduct, and undifferentiated behaviour disorders and hyperactivity. RESULTS--On the parental questionnaire screen, 36% of the cases and 22% of the controls had a behaviour disorder and on the teacher questionnaire the proportions were 27% and 12% respectively. Hyperactivity was significantly more common among male cases than their controls (21% v 5.0%) but differed little among female cases and controls (9% v 7%). CONCLUSIONS--Improving neonatal survival of low birthweight infants is accompanied by a higher prevalence of behaviour disorders. The long term implications for psychiatric morbidity and other adult disease must be monitored. 相似文献

SUMMARY Gastrocolic fistula is most often related to malignancy or previous gastric surgery. It is an uncommon complication of benign gastric ulceration in patients who have not had a previous operation. Benign gastrocolic fistula associated with peritonitis is extremely rare — this case is only the fourth ever reported. The patient presented with an acute abdomen, and subsequent investigations demonstrated a gastrocolic fistula of benign aetiology. 相似文献

Melatonin has been proposed as a treatment for Alzheimer's disease based on the demonstration of antioxidant and "anti-amyloid" effects in vitro and in vivo. Chronic melatonin therapy in old, amyloid plaque-bearing transgenic mice was studied. Tg2576 mice started melatonin treatment at 14 months of age. After 4 months of treatment, there were no differences between untreated and melatonin-treated mice in cortical levels of soluble, formic acid extracted, or histologically detectable beta amyloid (Abeta), nor in brain levels of lipid peroxidation product (total 8,12-isoprostane F(2alpha)-VI), despite marked elevations in plasma melatonin. We conclude that melatonin fails to produce anti-amyloid or antioxidant effects when initiated after the age of amyloid plaque deposition. These findings diminish the possibility that melatonin will be useful for the treatment of established Alzheimer's disease. 相似文献

Experimental intrahepatic portacaval anastomosis: use of expandable Gianturco stents 总被引:2,自引:0,他引:2
Original Gianturco expandable stents and their modifications were used to create an experimental intrahepatic portacaval anastomosis (EIPCA) in 30 young domestic swine without portal hypertension. The study focused on the design of a suitable stent, the technique of its application, and the evaluation of short-term patency of the EIPCA. A stent with a 2.5-cm-long body and wire skirts on both ends was most suitable for EIPCA creation. Well-positioned stents shunted most of the portal blood in the inferior vena cava circulation and remained patent for 4-6 weeks. Ingrowth of liver parenchyma and abundant proliferation of the intima and connective tissue inside the stent lumen in these rapidly growing animals gradually decreased EIPCA patency, and thrombus formation with diminished blood flow closed them completely. 相似文献
