| 1 | Steatosis and steatohepatitis in postmortem material from Northwestern Greece显示文摘AIM: To determine the prevalence of steatosis and steatohepatitis in a series of autopsies in Northwestern Greece. METHODS: Liver biopsy material from a total of 600 autopsies performed over a period of 2 years (2006-2008) to def ine the cause of death was subjected to histological examination. Patient demographic data were also collected. Tissue sections were stained with different dyes for the evaluation of liver architecture, degree of fibrosis and other pathological conditions when necessary. RESULTS: Satisfactory tissue samples for histological evaluation were available in 498 cases (341 male, 157 female) with a mean age of 64.51 ± 17.78 years. In total, 144 (28.9%) had normal liver histology, 156 (31.3%) had evidence of steatosis, and 198 (39.8%) had typical histological findings of steatohepatitis. The most common causes of death were ischemic heart disease with or without myocardial infarction (43.4%), and traffic accidents (13.4%). CONCLUSION: A high prevalence of steatosis and steatohepatitis was detected in postmortem biopsies from Northwestern Greece. Since both diseases can have serious clinical consequences, they should be considered as an important threat to the health of the general population in Greece. | Christos D Zois Gerasimos H Baltayiannis Anna Bekiari Anna Goussia Peter Karayiannis Michalis Doukas Demetrios Demopoulos Antigoni Mitsellou Theodoros Vougiouklakis Vasiliki Mitsi Epameinondas V Tsianos | 2010 | World Journal of Gastroenterology2010，16，31： | 4 |
| 2 | Low-grade central osteosarcoma of distal femur, resembling fibrous dysplasia显示文摘We report a case of a 32 year-old male, admitted for a lytic lesion of the distal femur. One month after the first X-ray, clinical and imaging deterioration was evident. Open biopsy revealed fibrous dysplasia. Three months later, the lytic lesion had spread to the whole distal third of the femur reaching the articular cartilage. The malignant clinical and imaging features necessitated excision of the lesion and reconstruction with a custom-made total knee arthroplasty. Intraoperatively, no obvious soft tissue infiltration was evident. Nevertheless, an excision of the distal 15.5 cm of the femur including 3.0 cm of the surrounding muscles was finally performed. The histological examination of the excised specimen revealed central low-grade osteosarcoma. Based on the morphological features of the excised tumor, allied to the clinical findings, the diagnosis of low-grade central osteosarcoma was finally made although characters of a fibrous dysplasia were apparent. Central low-grade osteosarcoma is a rare, well-differentiated sub-type of osteosarcoma, with clinical, imaging, and histological features similar to benign tumours. Thus, initial misdiagnosis is usual with the condition commonly mistaken for fibrous dysplasia. Central low-grade osteosarcoma is usually treated with surgery alone, with rare cases of distal metastases. However, regional recurrence is quite frequent after close margin excision. | Haris S Vasiliadis Christina Arnaoutoglou Sotiris Plakoutsis Michalis Doukas Anna Batistatou Theodoros A Xenakis | 2013 | World Journal of Orthopedics2013，4，4： | 1 |
