Correlation between intracoronary 201Tl myocardial scanning, coronary angiography and left ventriculography

One hundred and six patients with angina pectoris who underwent routine coronary angiography and left ventriculography were given intracoronary injection of thallium 201. The myocardial images had excellent resolution because of lack of interference from the background activity. The myocardial images and the left ventriculograms showed 94% correlation. Correlation between scans and EKG was lower. There was no correlation between the degree of coronary artery stenosis and 201Tl scan. Currently, the intracoronary injection of 201Tl at rest does not yield additional information to coronary angiography and left ventriculography.     

Caroli disease: high-frequency US and pathologic findings

Three infants with nonobstructive bile duct dilatation (Caroli disease) are described. The bile duct pathology was associated with autosomal recessive polycystic kidney disease in two patients and with severe destruction of the renal parenchyma of unknown origin in the other. Sonograms of the liver showed, besides bile duct dilatations, intraluminal bulbar protrusions, bridge formation across dilated lumina, and portal radicles partially or completely surrounded by dilated bile ducts. Liver biopsy was performed in two patients, and in one patient, the biopsy sample confirmed the findings noted on sonograms. These findings support the hypothesis that the normal embryogenesis of intrahepatic bile ducts is arrested in the pathogenesis of this disease.     

Early developmental outcome after the Norwood procedure for hypoplastic left heart syndrome

OBJECTIVE: To assess intellect and adaptive behavior in children with hypoplastic left heart syndrome (HLHS) who had undergone at least two surgical stages of the Norwood procedure. METHODS: Fourteen children with HLHS >3 years of age participated in the study. The patients underwent intelligence quotient (IQ) testing, and their parents were interviewed regarding their children's adaptive behavior. Results were compared with those of 10 family controls. Outcomes were studied for possible correlation with perioperative variables. RESULTS: Among the HLHS patients, the median scores for full scale IQ and adaptive behavior were 88 and 91, respectively (normal = 100 +/- 15). One child met criteria for mental retardation. Family controls scored generally higher than did HLHS patients, but only differences in adaptive behavior were statistically significant. A negative correlation was found between stage I circulatory arrest time and full scale IQ. CONCLUSIONS: Children with HLHS most often function in the low-normal range of intelligence and adaptive behavior. A prolonged circulatory arrest time may result in decreased intellectual function.     

白蛋白置换液替代血浆置换治疗难治性肝炎高胆红素血症

我们曾应用血浆置换治疗难治性病毒性肝炎高胆红素血症，取得了一定的疗效。但血浆作为置换液可能会引起丙型或乙型等肝炎病毒的感染。自１９９６年２月至１９９８年３月，我们探索以白蛋白替代血浆置换治疗２９例难治性病毒性肝炎高胆红素血症的病人，现将结果报告如下。...
