If sonomicrometry transducers could be implanted permanently into the diaphragm, direct measurements of costal and crural length and shortening could be made during recovery from the laparotomy and then indefinitely in an awake, non-anesthetized mammal. We report results from six canines in which we successfully implanted transducers onto the left(More)
If costal and crural diaphragm segments can perform as separate muscles, then CO2-stimulated ventilation may elicit differential segmental function. We studied diaphragm segmental length, shortening, and electromyogram (EMG) activity in 10 awake dogs chronically implanted with sonomicrometer transducers and EMG electrodes. During CO2 rebreathing, segmental(More)
In this study, the case of a patient presenting a second hepatocellular carcinoma 13 years after resection of a first tumor of the same type is reported. In this case, etiological investigations remained negative, but an incomplete form of syndromatic Alagille syndrome with paucity of bile ducts in the nontumoral tissue was detected and associated with(More)
Studies have shown that the number of units of blood transfused perioperatively in patients operated on for colonic cancer has a progressively strong negative influence on survival. The present study, involving 198 patients with rectal cancer, was done to determine if perioperative blood transfusions had any prognostic significance. Multivariate regression(More)
General anesthesia has been shown to induce a cephalad shift of the end-expiratory position of the diaphragm in recumbent human subjects. The authors used the technique of sonomicrometry in chronically instrumented dogs to measure the length changes occurring in the costal and crural diaphragm during anesthesia. Seven dogs were studied in lateral decubitus;(More)
This study was carried out to determine the effect of perioperative blood transfusions on the survival of patients operated on for colorectal cancers. Cox's regression analysis was applied to 281 patients operated for cure of Dukes' stage A, B or C disease. Other variables studied were age, sex, tumour location, and preoperative hemoglobin, lymphocyte and(More)
Extracorporeal shock waves represent a new method to treat gallstones. This study was designed to evaluate: 1) the effectiveness of a recently available lithotripter (EDAP LT 01) for gallstone fragmentation; 2) adverse tissue reactions after treatment; 3) the optimum conditions for use of this apparatus in man. A human cholesterol stone was surgically(More)
A preparation of cyclosporine A (CsA) in small liposomes (300 nm) was tested in a rat model of heterotopic cardiac allograft. At a daily dose of 1,5 mg/kg during 14 days, the graft survival rate was 30.4 +/- 2.8 days with a liposome-CsA solution versus 16 +/- 2.3 days with a Cremophore-CsA solution (p less than 0.01). Animals treated with the liposome-CsA(More)
