[Crush injury and compartment syndrome]

Crush injury of an extremity occurs when a limb is compressed between two hard surfaces, to the point where vascular supply is impaired and vulnerable tissues undergo necrosis. Most commonly, limbs are crushed during auto versus pedestrian accidents, motor vehicle crashes, and industrial accidents. However, during natural disasters such as earthquakes, building collapses, landslides, mine cave-ins, and acts of war with mass civilian casualties, epidemics of limb crush injuries can occur. The large number of casualties requiring specialized medical care can easily overwhelm medical systems, particularly if medical facilities are simultaneously affected by the disaster. This article reviews the acute management of vascular and soft tissue injuries in the emergency department

Epidemiologic prevalance of malignant epidermal tumor in 68 patients of Beasat hospital between 1383 to 1387

Skin is the largest organ of body. It is a perfect thermal barrier and protected the body against minimal invasive or micro organism invasion. This cross sectional and retrospective study is done on 68 patients referred to pathology laboratory of beasat hospital between 1383 to 1387. Demographic information, age, sex, site of lesion and pathologic report is obtained of pathology files. At last the results were analyzed by statistical soft ware spss 15. The cause of malignant epidermal neoplasm with respect to pathologic report included, 60 cases [88.2%] BCC, 5 cases [3%] SCC and 3 cases [4.5] malignant melanoma. The average age for BCC [55 +/- 13.5], SCC [61.4 +/- 15.7] and melanoma [61.3 +/- 12.4]. The most site of skin involvement was sun exposed areas. The study has shown that basal cell carcinoma [BCC] is the most common coetaneous malignancy and elderly patient are typically affected. Sun expose areas [with regard to site of involvement] is a potential carcinogen for malignant epidermal neoplasm
