A prospective study was performed to evaluate the efficacy of technetium-99m-sestamibi and technetium-99m-pertechnetate subtraction scanning and US for imaging parathyroid glands in primary hyperparathyroidism. Sixty-three patients were surgically treated for primary hyperparathyroidism (HPT). Preoperative scintigraphy and US were performed in all cases.(More)
Hyperlipidaemia of 18 male and 20 female patients following successful renal transplantation was treated with daily 20 mg fluvastatin (Lescol) for 12 weeks. The patients were several months after transplantation, and their total cholesterol levels exceeded 6.5 mmol/l following an 8-week diet. The effect of fluvastatin on the levels of total cholesterol,(More)
The relative DNA contents of thyroid cell nuclei were measured in surgically removed thyroid tissue of 50 patients by means of cytofluorimetry. Smears were prepared immediately after removal of the thyroid nodules according to the classical Feulgen technique. The fluorescence intensities were always compared with those of healthy thyroid tissue prepared in(More)
Introduction: We retrospectively reviewed the data of patients with papillary thyroid cancer who were node positive and treated at our department between 1955 and 1994. Of 362 cases of papillary cancer, 134 were identified with lymph-node metastases (37%). Methods: Two types of dissection procedures were applied by a large community of surgeons. When only(More)
PURPOSE To establish an animal model for use in evaluation of early morphologic changes of pulmonary fibrosis by means of precise correlation of findings at thin-section computed tomography (CT) and pathologic findings. MATERIALS AND METHODS Bleomycin (1.0-2.5 U per kilogram of body weight) was delivered selectively into the left lower lobe bronchus via(More)
RATIONALE AND OBJECTIVES To assess the early phase of radiation-induced lung injury using high-resolution computed tomography (CT) under experimental conditions and to perform precise CT-pathologic correlation. METHODS Five Yorkshire pigs received a single dose of 12.5 Gy to the right lower lung. Computed tomographic images were obtained at 2-week(More)
RATIONALE AND OBJECTIVES The authors sought to develop a reliable animal model for experimental pulmonary infarction, to evaluate it with radiologic-pathologic correlation, and to determine the use of high-resolution computed tomography (HRCT) in monitoring parenchymal lung damage due to infarction. METHODS Selective left lower lobe pulmonary artery(More)
Parallel studies were performed using microfluorimetric DNA determination and X-ray microanalysis on the same thyroid biopsy material to compare the intranuclear DNA and monovalent electrolyte contents (Na+, K+, Cl−). Samples were taken from apparently healthy, adenomatous, and cancerous parts of human thyroid glands removed surgically. The time interval(More)
The aim of this observational study was to compare the effect of calcium and alfacalcidol supplementation on the regression of hyperparathyroidism and on prevention of osteopenia in patients up to 3 years after renal transplantation. Two historical cohorts were compared for that purpose. One hundred and fifty-nine patients received calcium carbonate(More)
