    Notes: Abstract One hundred thirty-eight patients with transplant renal artery stenosis (TRAS) were identified among 1200 patients undergoing renal transplantation in our university hospital. Severe systemic hypertension was the main symptom leading to a diagnosis of TRAS. Only 88 TRAS patients were given interventional treatment consisting of percutaneous angioplasty (PTA; n=49) or surgical repair (SR; n=39). The immediate success rate was 92.1% for SR and 69% for PTA. The long-term success rate was 81.5% for SR and 40.8% for PTA, with a follow-up period of 56.7±22.4 months (SR group) and 32±28.1 months (PTA group). PTA morbidity reached 28%, compared to 7.6% in the SR group. In spite of these results, we still favor PTA as a first line interventional treatment when TRAS is recent, linear, and distal and primary SR in cases of kinking and proximal TRAS.

    Notes: Abstract One wonders whether the use of cyclosporin, histamine receptor antagonists, low doses of steroids, and early diagnosis and treatment actually modify the incidence, morbidity, and mortality of gastrointestinal (GI) and pancreatic complications in renal transplantation. To find out, we reviewed 614 kidney transplant recipients between January 1984 and December 1988. One hundred patients (16.2%) were found to have GI and/or pancreatic complications in the following distribution: 9.6% gastroduodenal, 1.3% pancreatic, 4% colonic, and 0.4% small bowel. None of the patients presenting a gastroduodenal ulcer had perforation or bleeding. Fifty-five percent of the patients with this complication had a past history of esogastroduodenal disease, compared to 19.6% in recipients without gastroduodenal complications. Some 4.4% of the patients had a small bowel or a colonic complication and four died of peritonitis due to bowel perforation. Mortality was 35% in those having intestinal resection and/or perforation with peritonitis. Sixteen percent of patients with colonic complications had a known history of diverticula, compared to 3% for those without colonic complications. The incidence of GI and/or pancreatic complications in renal transplant recipients remains high and has caused 1.1% of the deaths in our series. Mortality is essentially due to upper GI bleeding, peritonitis following perforation, and infectious colitis. Better detection of gastroduodenal and colonic disease before transplantation seems to be mandatory. Prevention with histamine H2 receptor antagonists and early surgical treatment of complicated colonic diverticula help to reduce the morbidity and mortality in kidney graft recipients.

    Notes: Early and late passage human embryonic lung fibroblasts were compared with early passage adult lung fibroblasts with regards to their survival (number of population doublings), after low dose rate ionizing radiation. It was found that early passage embryonic cells are quite resistant to this type of radiation. Late passage embryonic and early passage adult fibroblasts are more sensitive to ionizing radiations. The results suggest that cell aging is accompanied by an increased sensitivity to low dose rate ionizing radiation and favor the idea that aging in vitro, expressed as a function of the fibroblast division potential, is correlated with aging in vivo.
