PURPOSE To compare MR imaging, radiography and bone scintigraphy in the diagnosis of stress injuries to bones of the pelvis and lower extremity. MATERIAL AND METHODS Fifty consecutive conscripts with clinical signs of a stress injury to bone underwent MR imaging and bone scintigraphy. Forty-three patients also had radiographs available. Bone scintigraphy(More)
BACKGROUND AND OBJECTIVE Ankle blood pressure may be a useful indicator of arterial stiffness. The main aim of the present study was to examine the relationship of ankle blood pressure measured in midlife with the risk of dementia with advancing age. A secondary aim was to examine the relationship of physical exercise capacity in midlife with the risk of(More)
BACKGROUND The ankle blood pressure is commonly used as a ratio to the brachial blood pressure, called ankle-brachial index (ABI). Very few studies have considered the independent value of the ankle blood pressure without indexing it to the brachial blood pressure. We examined the value of ankle blood pressure, together with the exercise blood pressure, as(More)
AIM To assess the effects of recombinant human growth hormone (rhGH) treatment in children with Prader-Willi syndrome. DESIGN A 1-year study and an observational follow-up visit 10 years later. METHODS In 20 patients with Prader-Willi syndrome (PWS): clinical assessment, laboratory tests, body composition analysis by dual energy X-ray absorptiometry,(More)
Background and Objective. We examined the association of elevated ankle blood pressure (ABP), together with exercise blood pressure, with incident cerebrovascular (CV) morbidity and mortality in a prospective follow-up study of 3,808 patients. The results were compared with pulse pressure, another indicator of arterial stiffness. Methods. Patients with(More)
This paper is a report from a pharmacoscintigraphic study with an Egalet constant-release system containing caffeine and natural abundance samarium oxide. First the formulation was tested in vitro to clarify integrity during irradiation in the nuclear reactor. Then six healthy male volunteers were enrolled into the in vivo study. The in vitro release of(More)
OBJECTIVE To investigate heart rate characteristics in dogs undergoing ovariohysterectomy following premedication with medetomidine or acepromazine. DESIGN Clinical trial. ANIMALS 43 client-owned dogs. PROCEDURE 24-hour ambulatory electrocardiography was performed beginning approximately 1 hour prior to administration of premedications. Dogs were(More)
I surgical patients, the effects of perianesthetic medications and the physiologic perturbations induced by tissue trauma modulate various aspects of bodily function, particularly cardiac electrical and autonomic nervous system activities. In dogs, perioperative alterations in cardiac electrical activity have been documented through electrocardiography but(More)
