Irradiation has been shown experimentally to cause accelerated development of atherosclerosis in exposed large arteries. However, occurrence of such an entity in carotid arteries of patients after treatment for head and neck carcinoma is unknown. Therefore, we reviewed 179 patient charts who had undergone head and neck operations with or without irradiation between 1979-1987. Of these 179 patients, 107 (59.8%) were dead at time of follow-up. Cause of death was unknown in 42 (40%) patients; in the remainder included: respiratory arrest--33; carcinoma-related--18; cardiac--6;pneumonia--7; and trauma--1. Average interval from treatment to death was 23.5 months. Of the 72 patients known to be alive, follow-up was obtained in 52 patients. Their average age was 64.9 years. Risk factors for atherosclerosis included: male gender--43; smoking--50; hypertension--9; diabetes--4; coronary artery disease--12; and peripheral vascular disease--4. Seventy-five per cent of these patients received postoperative irradiation. Average follow-up was 64.5 months. Duplex scans were performed on 34 patients. Three patients had common or internal carotid stenoses greater than 75 per cent. All of these patients had received irradiation and none of them were symptomatic. Seven patients had carotid stenoses between 50 to 75 per cent; five of these had received irradiation. Of these five patients, one had a stroke 60 months postoperatively, and one had a TIA 36 months postoperatively. The remaining 58 patients (of which 48 had irradiation) had carotid stenoses less than 50 per cent and none were symptomatic.(ABSTRACT TRUNCATED AT 250 WORDS)

Clostridium septicum is a major cause of spontaneous, nontraumatic gas gangrene. Unlike Clostridium perfringens, C. septicum is relatively aerotolerant and thus appears to be more capable of initiating infection in the absence of obvious damage to tissues. Six cases illustrate the clinical setting and fulminant nature of spontaneous gangrene caused by C. septicum. A lesion in the colon such as carcinoma is often present and is presumed to serve as a portal of entry to the bloodstream. Diabetes and leukopenia are also common predisposing conditions; compromise of vital host responses may facilitate proliferation of those organisms that settle out in the tissues. Acute lymphoma or leukemia during a course of chemotherapy is accompanied by damage to bowel mucosa and granulocytopenia, thus predisposing to spontaneous clostridial gangrene. Infection progresses in a fulminating manner; the majority of patients die within 24 hours of onset. Characteristic symptoms and signs include excruciating pain (although a sense of heaviness may be the only early symptom), swelling of tissues, crepitance, and bulla formation. A hallmark of C. septicum infection is the absence of acute inflammatory cells in involved tissues or in bulla fluid. A series of laboratory investigations demonstrated that fluid obtained from a bulla adversely affected the viability, morphology, and function of polymorphonuclear leukocytes (PMNs), which may explain the paucity of PMNs in involved tissues and may in part contribute to the fulminant progression observed in infection due to this organism.

We assessed the prevalence of previously unrecognized hemochromatosis among patients in whom diabetes mellitus was diagnosed after the age of 30 yr, and we evaluated the positive predictive value of biochemical screening tests for hemochromatosis in diabetic subjects. Thirty-eight of 572 patients screened (6.6%) had a serum ferritin level greater than 324 micrograms/L; 16 patients had normal levels on repeat testing. Four patients' serum ferritin levels fell to less than 400 micrograms/L. Seven of 18 patients with a persistently elevated serum ferritin level did not undergo a liver biopsy because of a recognized cause of hyperferritenemia (carcinoma, alcoholism, or systemic lupus erythematosus). The diagnosis of hemochromatosis seemed certain in 1 of 3 patients who were not biopsied for technical reasons. Of 8 patients biopsied, 2 had hemochromatosis, 4 had fatty liver, 1 had hemosiderosis, and 1 had a chronic inflammatory cell infiltrate with no iron deposition. Of 4 patients with a raised transferrin saturation level, 2 had raised serum ferritin levels and hemochromatosis, 1 had raised serum ferritin and hemosiderosis on liver biopsy, and 1 had a normal transferrin saturation level on repeat testing. Two of 3 cases of hemochromatosis had other clinical markers of the condition. Therefore, routine screening of diabetic patients for hemochromatosis is not necessary, because patients with hemochromatosis will often have other clinical features of the disease. When screening diabetic patients for hemochromatosis, it should be remembered that a persistently raised serum ferritin level has a low positive predictive value (16.6%) and that a normal transferrin saturation level does not exclude the diagnosis.

This article describes the surgery of tropical pancreatitis as practiced in a region of high incidence, based on the experience at 2 centers: the Department of Surgical Gastroenterology and Proctology, Government General Hospital, Madras, Tamilnadu (a tertiary-care referral unit) where 52 patients were diagnosed and 40 were operated on between 1982 and 1987; and the Department of Gastroenterology, Deva Matha Hospital, Koothattukulam (a specialized center located in the main endemic area of Kerala), where 116 patients were diagnosed and 33 operated on between 1983 and 1988. The latter series is described in detail with emphasis on the preoperative imaging, operative findings, surgical procedures, complications, and results of surgery. The experience of other centers in southern India is summarized and discussed. The disease is obviously different from chronic pancreatitis in the West. Special problems of tropical pancreatitis, particularly the management of diabetes and the association of pancreatic carcinoma at a young age, are discussed.

The frequency of known causative factors of cerebral infarction was studied in 244 cases of first ever stroke due to cerebral infarction proved by computed tomography or at necropsy who were registered in the first two years of a prospective community based study. Risk factors for cerebral infarction were present in 196 (80%) cases; hypertension in 126 (52%); ischaemic heart disease in 92 (38%); peripheral vascular disease in 60 (25%); a cardiac lesion that was a major potential source of embolism to the brain in 50 (20%); transient ischaemic attacks in 35 (14%); cervical arterial bruit in 33 (14%); and diabetes mellitus in 24 (10%). Thirty one patients (13%) were in atrial fibrillation. Of the 48 patients who were free of risk factors or a major potential cardiac source of embolism at the time of the stroke, 18 were found to have hypertension after the stroke and 10 to have non-atheromatous non-embolic conditions (migrainous cerebral infarction (three), arteritis (two), inflammatory bowel disease (one), arterial trauma (one), autoimmune disease (one), carcinoma of the thyroid (one), and major operation (one). In 20 patients no causative factors could be identified. In this unselected series of patients with first ever stroke due to cerebral infarction most of the strokes were presumed to be due to either atheromatous arterial disease or embolism from the heart, and only 4% (95% confidence interval 2 to 7%) were probably due to non-atheromatous non-embolic causes. This has implications for research into strokes and allocation of public health expenditure.

Pancreatojejunal anastomosis disruption still represents the main postoperative complication after pancreatoduodenectomy. In this study, a technique of occlusion of the residual pancreatic stump instead of pancreatojejunal anastomosis is proposed. Between March, 1981 and August, 1987, we performed 51 pancreatoduodenectomies, using Neoprene injection in the Wirsung duct, for carcinoma of the pancreatic head (28 cases), ampullary carcinoma (12 cases), islet cell carcinoma (5 cases), and chronic pancreatitis (6 cases). We observed a 33.3% overall morbidity, with a 5.8% operative mortality. The complications observed seemed not to be related to the technique of pancreatic stump occlusion, except for 2 pancreatic fistulas which spontaneously resolved. Abdominal ultrasound and computed tomography scan performed during the follow-up did not show any significant morphological alteration of the residual stump. Pancreatic endocrine function was assessed in 10 patients by evaluating blood glucose, plasma insulin and plasma glucagon levels both fasting and after oral glucose, and intravenous arginine infusion. These tests were performed before surgery and 15 days, 6 months, 1, 2, and 3 years after surgery. The results showed that 60% of the patients had impaired glucose tolerance before surgery and the percentage did not significantly change up to 3 years later (75%). No patient developed diabetes mellitus, and only 1 patient progressed from a normal to an impaired glucose tolerance. In conclusion, intraductal injection of Neoprene after pancreatoduodenectomy seems to be a safer procedure compared to pancreatojejunal anastomosis and does not induce a post-surgical diabetes.

The risk of invasive cervical carcinoma (No 180 by the International Classification of Diseases in 1975) was analysed in comparison to a control group of 599 healthy women. From these populations two subgroups were isolated: autochthonous women born in Upper Silesia (162 cases + 408 control women) and immigrants (107 cases + 191 controls). The risk of carcinoma was higher in the second subgroup. The analysis demonstrated a significant correlation between the risk of invasive cervical carcinoma among women doing heavy work with exposure to industrial dusts and gases in working environment. A significantly higher risk of invasive cervical carcinoma was observed also in the populations of women who had lithiasis (cholelithiasis, nephrolithiasis, bladder calculosis), diabetes, hypertension and venereal diseases or had had operations on the genital system, mainly for erosions and myomas.

The purpose of this study was to ascertain the influence of acute pancreatitis upon the course of chronic pancreatitis, its complications, the need for surgical treatment, and mortality, in alcoholic men. The studied population was composed of 222 men; 110 had never had acute pancreatitis and 112 had presented at least once with acute pancreatitis. The cumulative probability to have a first bout of acute pancreatitis was 41.5 percent, 2 years after the onset of chronic pancreatitis. There was no difference in follow-up but clinical onset of chronic pancreatitis was earlier in the "acute pancreatitis" group. There was no difference in the prevalence of biliary strictures, non-alcoholic hepatic disease or need for surgery. On the contrary, diabetes mellitus, alcoholic hepatic disease were less frequent and pseudocysts were more frequent in the "acute pancreatitis" group. We observed 56 deaths. The comparison of mortality and cumulative survival rates showed a lower mortality in the "acute pancreatitis" group (p less than 0.02 and 0.05, respectively). The main causes of death were alcohol-related hepatic disease, postoperative mortality, and carcinoma Alcoholic cirrhosis was more frequent in patients who died in the "no acute pancreatitis" group. We conclude that: a) acute pancreatitis is an early complication of chronic pancreatitis in one case out of two; b) clinical onset of chronic pancreatitis occurs earlier in patients who presented with acute pancreatitis; c) need for surgery is not different; d) alcoholic hepatic disease is more frequent in the "no acute pancreatitis" group; e) mortality is lower in the "acute pancreatitis" group.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors evaluate five-year ultrasonographic material (13,672 examinations) focused on non-cystic liver disease. 8212 examinations (60.1%) were made as part of examinations of the gallbladder, 4919 (36%) as part of examination of the right sub-costal area or other organs and only 541 examinations (3.96%) were focused in the first place on the liver. The total number of examined patients included 7830 women (57.3%) and 5842 men (42.7%). Most frequently the ultrasonographic picture of steatosis was found--in 747 patients (5.46%), cirrhosis of the liver in 45 patients (0.33%), primary carcinoma of the liver was present in 7 patients (0.05%) and tumour metastases in 63 patients (0.46%). The group of women with steatosis comprised 42 diabetic women (32.06%), 78 overweight women (59.5%) and 18 with excessive alcohol intake for several years (13.7%). In the group of men with steatosis there were 48 diabetics (7.79%), 92 overweight (14.9%) and 479 with excessive alcohol intake extending over several years (77.7%). In the group of 34 men with cirrhosis excessive alcohol intake for years was found in 31 (91.2%), in the group of eight women with cirrhosis in five instances (62.5%). In abdominal ultrasonography liver disease must be actively searched for, in particular in patients with long-term alcohol intake, overweight, diabetes and long-term use of various hepatotropic drugs.

We report the case of a middle-aged man with a 6-month history of diabetes treated with insulin. He was referred for diabetes control and education. Six weeks after we saw him, he was euglycemic (hemoglobin, Hgb A1C 5.9%), but returned because of weight loss, diarrhea, and abdominal cramps. Pancreatic adenocarcinoma was diagnosed. We review the literature on the relationship between diabetes mellitus and pancreatic carcinoma with particular emphasis on situations in which recent-onset diabetes may be a harbinger of pancreatic carcinoma. Several reports are cited in which the onset of diabetes mellitus in middle-aged patients antedated by a short time the onset of clinically recognizable pancreatic carcinoma. An otherwise silent pancreatic carcinoma may present as new-onset diabetes. Although rare, pancreatic carcinoma should be considered in a recently diagnosed middle-aged diabetic person with unusual manifestations, e.g., abdominal symptoms and continuous weight loss despite euglycemia.
