A hand-held pressure algometer with a pressure sensitive strain gauge at the tip was used to measure the pressure-pain threshold (PPT) in the temporal region of healthy volunteers. Various sizes of circular tips and various application rates were tested before selecting an area of 0.5 cm2 and a constant application rate of 0.68 N X sec-1 for future use. A(More)
The purpose of this study was to investigate whether an age-associated impaired acute-phase response exists. Nine healthy elderly volunteers (median, 66 years; range, 61 to 69 years) and eight young controls (median, 24 years; range, 20 to 27 years) were given an intravenous bolus of endotoxin (2 ng/kg). The rectal temperature was monitored continuously,(More)
A total of 79 consecutive patients with pituitary tumours were screened for multiple endocrine neoplasia type 1 (MEN-1). The 79 patients included 21 patients with acromegaly, nine with Cushing's disease, 18 with prolactinomas, three with mixed pituitary adenomas (GH and PRL), and 28 patients with no detectable hypersecretion of hormones. The screening(More)
From 1977 to 1988 60 patients were treated for large pericardial effusion. The operation consisted of a small left anterior thoracotomy with formation of a pericardial window. In 28 patients (47%) the etiology was a malignant disease. Eight patients (29%) had malignant cells in the pericardial fluid and 23 patients (82%) had metastases to the pericardium.(More)
The stimulation of transepithelial sodium transport by arginine vasotocin (AVT) and the ability of prostaglandin E2 (PGE2) to inhibit the AVT dependent sodium transport was examined on pieces of frog skin taken from different regions of the frog. The basal sodium transport was of the same magnitude in the abdominal, thoracal and upper and lower dorsal(More)
