The Leicester Royal Infirmary serves a large immigrant community from the Indian subcontinent. We surveyed referrals to the Dermatology Department over the months of November 1986 and September 1987. In both surveys atopic dermatitis (AD) was significantly more common among the Asian patients.

Autopsy data from 78 patients with end-stage renal disease (ESRD) treated with long-term hemodialysis were examined. Various pancreatic abnormalities were found in 47 (60%) patients. The most prevalent abnormality was pancreatitis which was seen in 22 patients (28%). Other lesions found with considerable frequency included fibrosis, hemosiderin deposits, calcification, cystic changes, amyloidosis and abscess formation. In addition hyalinization, atrophy or absence of islands of Langerhans and necrosis of peripancreatic fat were seen in several cases and inspissated secretions, focal ductular epithelial metaplasia and dilatation were noted in some patients. Comparison of the present data with those of a large survey of ESRD patients conducted prior to dialysis era indicates a considerable increase in the prevalence of pancreatic pathology in ESRD patients sustained by long-term hemodialysis treatment.
Necropsy findings of hepatobiliary system from 78 patients with end-stage renal disease maintained on hemodialysis are reported. Ninety percent of the patients exhibited some abnormalities. Multiple abnormalities often coexisted in each patient. Hepatomegaly was found in 50% of the patients and could be attributed to a discernible cause in all but two of the affected patients who had isolated hepatomegaly. Hepatic congestion was also prevalent and was complicated by fibrosis, cardiac cirrhosis, and centrilobular necrosis and hemorrhage in some patients. This was associated with chronic fluid overload, hypertension, and/or cardiovascular disease in the affected patients indicating the importance of adequate control of these factors. Mild periportal hepatic fibrosis, fatty metamorphosis, triaditis, hemosiderosis, and cystic changes were also seen with some frequency--the latter were associated with polycystic kidney disease and were complicated by massive intracystic hemorrhage and abscess formation, each in one patient. Chronic active hepatitis was found in three patients and was associated with chronic HBs antigenemia in one patient and presumed non-A, non-B infection in two. Nearly 22% of the patients showed either cholelithiasis at autopsy or before cholecystectomy due to complications. Significant negative findings included lack of acute viral hepatitis, silicone hepatosis, and recently described focal anoxic lesions associated with erythrocyte sludging. In conclusion, the present study has demonstrated the spectrum of hepatobiliary pathology in a large group of patients with end-stage renal disease maintained on hemodialysis.
The pathological data obtained from postmortem examination of the gastrointestinal tract in 78 chronic hemodialysis patients are reported. All but two of the patients exhibited some gastrointestinal abnormalities. Multiple abnormalities often coexisted in one individual. Esophagitis, gastritis, duodenitis, enteritis, and colitis were seen with considerable frequency. However, extensive hemorrhagic, ulcerative, and pseudomembranous lesions frequently seen in untreated uremia were generally lacking. Evidence of peptic ulcer disease was found in one-fourth of the patients confirming the increased predisposition of dialysis patients to this complication. Several patients exhibited various ischemic phenomena including thrombosis, embolism, and infarction of various segments of the gastrointestinal tract. In addition, numerous other abnormalities were found throughout the gastrointestinal tract with lesser frequency. The data indicate that various gastrointestinal abnormalities commonly occur in patients with endstage renal disease despite uremia control by hemodialysis. However, the observed abnormalities are different from those reported in untreated uremia.
