BACKGROUND The use of adjuvants after curettage has been well established for the treatment of giant cell tumor of bone. The purpose of this study was to analyze the rates of recurrence following different types of treatment as well as the influence of various factors of tumor presentation on those rates. METHODS The data regarding benign giant cell(More)
We assessed the anatomy of the anterior cruciate ligament (ACL) and femoral intercondylar notch on cryosections from one cadaveric knee specimen in the coronal oblique plane oriented parallel to the intercondylar roof. We determined the course of the ACL, the widths of the cruciate ligaments at intersection, and the intercondylar notch configuration on(More)
A retrospective study of 741 patients with medullary thyroid carcinoma diagnosed between 1967 and 1991 was carried out by members of the German Medullary Thyroid Carcinoma Study Group to evaluate prognostic factors. A total of 559 patients (75%) were considered to have sporadic disease, and 182 (25%) had the familial type. The sex ratio (male to female) was(More)
OBJECTIVE The purpose of this study was to quantify quadriceps tendon length, thickness, and insertion in relation to the suprapatellar fat pad. SUBJECTS AND METHODS We used three methods to analyze the anatomy of intact quadriceps tendons and insertions into the patellar base: MR arthrography (53 knees with intact extensor mechanisms), gross anatomy (16(More)
OBJECTIVE This randomized, double-blind, crossover study was undertaken to compare the incidence of headache recurrence after treatment with naratriptan or sumatriptan in migraine patients with a history of frequent headache recurrence (recurrence in > or =50% of successfully treated attacks). BACKGROUND Although the selective 5-hydroxytryptamine, (5-HT1)(More)
BACKGROUND Proteinuria is known to affect the proximal tubular epithelial structure and function. The present study tested the hypothesis that chronic proteinuria leads to hyperplasia of proximal tubular epithelium. METHODS This hypothesis was tested by morphometric analysis of the renal biopsy specimens in two groups of patients. Group A (N = 15) was(More)
The LIAISON thyroid hormone assays TSH, FT4, FT3, T4 and T3 were evaluated by determining the imprecision, the reference ranges, the functional sensitivity (TSH), the dilution characteristics (accuracy) (FT4, FT3), and the recovery after spiking (TSH, T4, T3). Furthermore, inter-method comparisons were performed with following methods: Elecsys (Roche(More)
