Testosterone (T) may be associated with enhanced spatial navigation in a number of rodent species, although the nature of the relation is equivocal. Similarly, numerous studies in humans generally have found that T is associated with enhanced spatial ability on a variety of paper and pencil tasks that may relate to navigational ability. However, relatively(More)
PURPOSE To retrospectively evaluate the imaging features of os peroneum fractures and associated peroneus longus tendon injuries at radiography and ultrasonography (US) and to retrospectively compare these imaging features with those of multipartite os peroneum. MATERIALS AND METHODS Institutional review board approval was obtained and informed consent(More)
Abstract Design and patients. We reviewed the MR appearances of six cases of longitudinal stress fracture of the lower extremity. Results. One fracture was in the femur and five were in the tibia. Four of the tibial fractures showed edema starting in the mid-tibia at the level of the nutrient foramen with the fracture on the anteromedial cortex. The other(More)
Objective. To describe the sonographic findings of septic arthritis of the acromioclavicular joint. Design and patients. A retrospective study of five male patients was carried out. Four of the patients were referred because of signs and symptoms suggestive of glenohumeral joint septic arthritis, one for signs and symptoms suggestive of septic arthritis of(More)
Opportunistic infections are a theoretical concern with the use of tumor necrosis factor antagonists, as these agents can impair host immunity. A 61-year-old man with rheumatoid arthritis being treated with only etanercept (soluble tumor necrosis factor receptor) and in remission from the rheumatoid arthritis presented with dorsal tenosynovitis of his right(More)
OBJECTIVE To review autoimmune disease complicating therapy with type I interferons (IFNs), specifically in the setting of hepatitis C virus (HCV) infection. METHODS This study describes 13 reported cases of drug-induced systemic lupus erythematosus (SLE) associated with IFN therapy for the period reported during 1990-2002 by searching MEDLINE. In(More)
We present a case of multicentric reticulohistiocytosis with pulmonary involvement. Scintigraphic evaluation with gallium-67 citrate demonstrated bilateral hilar uptake on 2 occasions. Possible mechanisms for gallium avidity are discussed. Gallium scintigraphy has a potential role for assessing systemic involvement in this disease.
We compared two enzymatic cholesterol methods with the standardized chemical method used in the Lipid Research Clinic's (LRC) program. The methods were used to measure total cholesterol and high density lipoprotein (HDL) cholesterol in heparin-MnCl2 supernatants of 1,812 sera collected over a 16-mth period from subjects who were sampled as part of the(More)
