BACKGROUND The results of case-control studies and anecdotal reports suggest that pancreatitis may be a risk factor for pancreatic cancer, but there have been no studies of sufficient size and power to assess the magnitude of the relation between these two diseases. METHODS AND RESULTS We undertook a multicenter historical cohort study of 2015 subjects(More)
Using a precise and accurate ultrasonic scanning technique we have measured the volume of the thyroid gland in vivo in 271 healthy subjects (13-91 yr old). In these subjects the mean (+/- SD) thyroid volume was 18.6 +/- 4.5 ml. A significant difference between males (19.6 +/- 4.7 ml; n = 139) and females (17.5 +/- 4.2 ml; n = 132) was found (P less than(More)
In patients with obstructive jaundice caused by malignant stricture of the extrahepatic bile duct we compared survival time, complication rates, hospitalisation requirements, and quality of life after palliation by endoscopic endoprosthesis or bypass surgery. During diagnostic endoscopic cholangiography 50 patients were randomised to the two treatment(More)
Data on the association between alcohol abuse and cancer morbidity are scarce in large cohorts of non-hospitalised alcoholic men and women. Of 18,368 alcohol abusers who entered an outpatient clinic in Copenhagen during 1954-87, 18,307 were followed and their cancer incidence was compared with that of the total Danish population. On average the 15,214 men(More)
Seventy-four addictive alcoholic subjects were investigated shortly after a period of excessive drinking and were compared with 18 alcoholic subjects who had not been drinking for at least six months. No difference was observed in total white cell count or number of circulating granulocytes. Lymphocyte count was significantly lower in alcoholics whose last(More)
BACKGROUND Smoking is a recognised risk factor for pancreatic cancer and has been associated with chronic pancreatitis and also with type II diabetes. AIMS The aim of this study was to investigate the effect of tobacco on the age of diagnosis of pancreatitis and progression of disease, as measured by the appearance of calcification and diabetes.

Thirty patients with multiple sclerosis (MS) [18 men and 12 women, mean age 40 years (range 22–50), disease duration 12 years (range 0.5–34), Kurtzke's Expanded Disability Status Score 6.0 (range 4.0–7.5)] were interviewed about bowel symptoms and studied using ano-rectal manometry. The results were compared with findings in healthy controls. Twenty-eight(More)
Eighty-nine ureteroscopies, comprising 102 renal units, were performed on 31 patients for diagnosis, treatment or follow-up of transitional cell tumors of the upper urinary tract. The indications were hematuria or filling defect (29 endoscopies), treatment of tumor (19) and follow-up (41), i.e. 33, 21 and 48 renal units. Ureteroscopy (including 2(More)
Decomposition of dietary fibers in the stomach and small bowel was studied in 13 healthy male volunteers. Liquid control meals were compared with test meals, which in addition contained a source of fiber (wheat bran or ispaghula husk) in random order. Aspirations were collected from the stomach, the proximal jejunum, the mid gut and the terminal ileum.(More)
