We evaluated the subsequent loss of bone from the proximal part of the ipsilateral and contralateral femora and from the lumbar spine of seven men and nine women who had a fracture of the tibia. The average age was sixty years. All of the fractures were unstable, and the involved leg bore no weight for an average of eight weeks. The bone mineral density was(More)
Immobilization is associated with increased bone resorption. To investigate the early onset of increased bone resorption, we evaluated 14 patients who were immobilized for 10 days because of lumbar disc protrusion. The fasting urinary hydroxyproline/creatinine ratio increased significantly after four days (P less than 0.01), reached a peak after 10 days(More)
Mechanical loading is necessary for maintenance of skeletal integrity, but the most effective type, intensity, and duration of exercise are not known. In vivo experiments have indicated that the strain generated by the stimulus is more important than the duration of the stimulus. To elucidate this question, we studied 5-month-old female Wistar rats(More)
The purpose of this study was to investigate whether bone loss in the hip, occurring after a fracture of the lower leg, persists many years after the fracture. In a long-term follow-up we measured bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA) of both hips and the lumbar spine in a group of 11 patients, 5 years after a fracture of the(More)
AIM To investigate the association between the use of proton pump inhibitors (PPIs) and acute interstitial nephritis (AIN). METHODS The Netherlands Pharmacovigilance Centre Lareb received seven case reports of AIN induced by various PPIs. In five of the reports it was mentioned that the diagnosis was confirmed by a renal biopsy. RESULTS The time to(More)
Heparin therapy may cause osteoporosis. The effects of short-term low-dose heparin are not known. We have studied the effects of short-term heparin administration, twice daily 5000 IU s.c., for 10 days on the biochemical parameters of bone turnover in six healthy male volunteers. No effects were observed on the urinary excretion of hydroxyproline and(More)
Severe psychosis in patients with Cushing's syndrome is rare and generally difficult to treat. We report a 46-yr-old woman suffering from Cushing's syndrome caused by an inoperable ACTH-producing lung carcinoma. She was initially treated with chemotherapy and radiotherapy. Six months later she presented with severe psychosis. Laboratory findings revealed a(More)
The aortoenteric fistula is a well-known but uncommon cause of gastrointestinal haemorrhage. It is usually secondary to previous reconstructive surgery of an abdominal aortic aneurysm. Primary aortoenteric fistula is a rare disorder which predominantly occurs in the duodenum. We report the case of a 76-year-old patient who presented with melaena and(More)
Immobilization is associated with increased bone resorption and decreased bone formation. We evaluated in a double-blind trial the effect of intranasal administration of salmon calcitonin on biochemical parameters of bone turnover in 32 patients immobilized for a prolapsed intervertebral disk. Calcitonin in a dose of two times 200 IU/day partially inhibited(More)
