BACKGROUND Conventional chondrosarcoma is the second most common malignant solid tumor of bone, and its management still poses a challenge for the orthopedic surgeon. Currently, tumor grade is the only parameter of prognostic significance besides stage and, possibly, resection margins. Additional independent prognostic markers therefore would be highly(More)
HYPOTHESIS Currently, the risk for postoperative acute pulmonary embolism (APE) is assessed clinically. We hypothesize that the expensive screening for the most common genetic thrombophilic clotting defect (factor V Leiden; R(506)Q) after exclusion of established clinical risk factors does not offer additional benefit to surgical patients. DESIGN We(More)
Sinus histiocytosis with massive lymphadenopathy or Rosai-Dorfman disease (RDD) is a rare histiocytic proliferative disorder of unknown etiology. Most patients present with lymph node involvement manifesting as adenopathy; however, RDD may arise primarily in a variety of extranodal sites, including bone. We report herein our experience with 15 cases of(More)
Abnormalities in the TP53 tumour suppressor gene were evaluated in 106 unselected breast carcinomas and compared to clinical outcome of the disease. Tumours were screened for p53 abnormalities using immunohistochemical staining and polymerase chain reaction-constant denaturant gel electrophoresis (PCR-CDGE) analysis, followed by PCR and direct sequencing.(More)
BACKGROUND Chondrosarcomas are common solid malignant tumors of bone, second in incidence only to osteosarcomas. The biologic evolution of chondrosarcomas is slow, requiring long follow-up intervals for meaningful survival analysis. METHODS This study describes the clinicopathologic profiles of 344 patients, 194 male and 150 female (M:F, 1.3:1.0), with(More)
OBJECTIVE To investigate the incidence and clinical and histopathologic features of giant cell (temporal) arteritis (GCA) in the Caucasian population of Iceland. METHODS All patients diagnosed between 1984 and 1990 were included. Case ascertainment for the study was done in 2 ways: 1) a computerized search from all hospitals and primary care clinics for(More)
The purpose of this study was to examine the pathology of all germ cell tumours of the testis diagnosed in Iceland 1955-2002. A total of 214 patients were included in the study. The current age-standardized incidence was found to be 6.1 per 100,000 and had increased almost fourfold during the study period. Seminoma was diagnosed in 55% of cases.(More)
Systemic amyloidosis results from the deposition of insoluble protein fibrils in various organs and tissues. To date, several different proteins have been associated with amyloid fibril formation, including immunoglobulin light chain, serum amyloid A protein, and transthyretin. Recent reports have shown that variant fibrinogen chains can form amyloid in(More)
The death certificate is an important source of data on disease incidence, prevalence and mortality. It should therefore be as accurate and complete as possible. Death certificates from 433 autopsied hospital patients were reviewed and matched against the results of post-mortem examinations. Significant discrepancies between the two documents were observed(More)
BACKGROUND During the past few decades, hospital autopsy rates have steadily declined throughout the Western world. This decline is mainly attributed to the introduction of advanced diagnostic techniques. Despite technological developments, discrepancy rates between clinical diagnoses and autopsy findings remain high. Few studies have addressed discrepancy(More)
