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)
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 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)
From 1979 to 1988 483 patients were admitted with primary spontaneous pneumothorax. All patients underwent thoracoscopy to identify the cause of pneumothorax. Chemical pleurodesis with instillation of tetracycline was performed if cysts less than 2 cm in diameter were found. If larger cysts were identified the patient underwent thoracotomy.
