Recombinant human interferon-alpha has been used in the treatment of several cancers, but there have been several reports that it may exacerbate psoriasis or trigger off its onset. We report four patients, three of whom first developed psoriasis and one who had an aggravation of the condition during treatment with interferon-alpha. Three of the patients had(More)
The objective of this study was to investigate the effects of high and low inhibitor soybean meals on the duodenal enzyme activities and on the possible regulatory role of gastrointestinal hormones in the pancreatic response. After an overnight fast, 11 healthy volunteers received an intraduodenal infusion of saline for 60 min. This was followed by infusion(More)
The extent of heart disease and its relationship to the serotonin metabolite 5-hydroxyindoleacetic acid (5-HIAA), was studied with M-mode, 2D and Doppler echocardiography in 42 consecutive patients, 30 females and 12 males, median age 63 (range 23-75) years with histologically verified mid-gut tumour, liver metastases and 24-h urinary 5-HIAA excretion above(More)
The exocrine pancreatic secretion of water, bicarbonate, amylase, trypsin, chymotrypsin, and lipase and the plasma concentration of immunoreactive secretin (IRS) were studied before and after repeated intraduodenal infusions of cattle bile in man. After endoscopic cannulation of the main pancreatic duct, juice was collected in 5-min samples for 20 min. A(More)
Seventy-five patients with advanced abdominal carcinoid tumors (65 midgut, 10 others) have been examined retrospectively to evaluate the role of surgical treatment as a principle, irrespective of stage of disease. Eighteen of 52 patients (35%) exhibited the carcinoid syndrome. Two or more primaries were found in 39% of patients with midgut lesion, 81% of(More)
Perfusion of the cat duodenum with sodium taurocholate (TC), 120 mmol/l, at pH 6.1 increased the plasma immunoreactive (IRS) concentration from 2.2 +/- 0.7 pmol/l to 29 +/- 6.1 pmol/l during the first 20 min. This was accompanied by an increased pancreatic secretion of fluid, while the chymotrypsin output showed a "wash-out' phenomenon. TC increased both(More)
Duodenal perfusion with sodium taurocholate (TC), pH 10.5 (60 mM, made isotonic with NaCl, 30 ml/h for 90 min), increased the plasma immunoreactive secretin level (IRS) from 2.1 +/- 1.0 to 19.1 +/- 6.0 pM (p less than 0.025; n = 6) in anaesthetized cats. Dose-response studies with TC, pH 7.2 (0-60 mM, made isotonic with NaCl, 45 ml/h for 20 min),(More)
BACKGROUND Mid-gut carcinoid tumours often present with liver metastases, and survival has then been less than 2 years in earlier reports. We have evaluated the effects of interferon therapy on clinical response and survival, with or without hepatic artery embolization in these patients. METHODS In a prospective study 30 female and 12 male patients, aged(More)

When 20 ml of 50 mmol/l pure synthetic bile salts (pH 6.5), of approximately the same composition as human bile, were infused into the duodenum of six healthy volunteers over 5 min during constant gastric aspiration, plasma immunoreactive secretin increased from 2.5 +/- 0.4 pmol/l to 3.6 +/- 0.5 pmol/l at 10 min (p < 0.025). Gastric acid secretion was not(More)
