REASON FOR PERFORMING STUDY The proximal metacarpal region is a common site of origin of lameness in the performance horse. A number of disease entities are recognised as causes of proximal metacarpal lameness but a definitive diagnosis is often elusive. Magnetic resonance imaging (MRI) is hypothesised to offer advantages over traditional imaging modalities(More)
PURPOSE The aim of this study was to determine the accuracy of anatomic palpation-directed injections in the office setting. METHODS Two hundred twenty-six shoulders in 208 patients were studied using a 0.2-Tesla extremity scanner after the injection of gadolinium-diethylene triamine pentaacetic acid-saline. All patients were injected in a sterile fashion(More)
BACKGROUND AND OBJECTIVE Local host-modulation therapy is an emerging approach to prevent disease progression in sites with moderate periodontitis. The combination of simvastatin and alendronate would be an intriguing host-modulatory strategy because of the bone-anabolic properties of simvastatin and the antiresorptive/bone-targeting characteristics of(More)
REASONS FOR PERFORMING STUDY The metacarpo/metatarsophalangeal (MCP/MTP) joint is a common site of lameness in the Thoroughbred racehorse. Radiographs may fail to show pathology consistent with the degree of lameness. With a high incidence of stress fractures occurring in the distal third metacarpal/metatarsal (MC3/MT3) condyles and proximal phalanx, a(More)
BACKGROUND In recent years, few studies have evaluated low-field magnetic resonance imaging (MRI) diagnoses compared with intraoperative findings of the knee. PURPOSE To determine the accuracy and sensitivity of low-field MRI scanners in diagnosing pathology of the menisci, cruciate ligaments, and osteochondral surfaces. STUDY DESIGN Cohort study(More)
Iliocaval compression syndrome is a significant disorder in a number of patients who have lower extremity venous complaints. The diagnosis may be suspected by positive findings on exercise strain gauge venous plethysmography and unilaterally increased ambulatory venous pressures. The diagnosis is confirmed by ascending and, in some instances, descending(More)
In humans, Saccharomyces cerevisiae (baker's yeast) is found infrequently as a commensal of mucosal surfaces and rarely causes infections. We describe a case of cutaneous septic emboli developing in a patient with relapsing acute myeloid leukaemia M6 who had recently been treated with clofarabine. Yeast forms were seen on skin biopsy and S. cerevisiae was(More)
A 20-year-old Caribbean woman with sickle cell anaemia was admitted with a 4-day history of fever and a painful swollen right ankle. She rapidly developed skin necrosis. The differential diagnosis is discussed. This case illustrates the difficulty in identifying the cause of cutaneous necrosis in an acutely ill patient. In our patient, histopathology(More)
Surgical treatment of anterior shoulder capsular deficiency has been a challenge for orthopaedic surgeons dealing with failed anterior shoulder stabilization procedures. We have used hamstring tendon autograft or tibialis tendon allograft to reinforce deficient anterior capsular tissue in patients with failed anterior shoulder stabilization. We performed a(More)
