Background: Sex identification of unknown skeletal human remains is of great importance in establishing identity and individuality. In adults, hip bone is the most reliable sex indicator because of its sexual dimorphism. Each population should have its own specific standards of identification. Objectives: Develop a logistic regression formula for adult sex identification using three-dimensional computed tomography (3D-CT) of the pelvis, and assessment of its validity in sex determination among a sample of Egyptian population at Suez Canal region. Materials and Methods: 141 pelvi-abdominal CT images (free of any pelvic orthopaedic disorder) were included; they were reconstructed to produce 3D-CT pelvic images; they were divided into calibration group (47 male & 47 female) and test group (47 CT images their sex is unknown to the observer), twenty radiometric variables were measured for the calibration groups. A logit response formula for sex prediction was developed and applied on the test group for sex prediction. Results: The logit response formula for the test sample showed sensitivity, specificity and overall accuracy 100%. Conclusion; Proposed method represent a quick and reliable metric method in establishing sex from the pelvis.

Burn injuries Medico-legal aspects Mortality predictors Burn injuries present a major public health concern. This study aimed to assess burn injuries and their outcome in patients admitted to the Burn Unit of Suez Canal University Hospital, Ismailia, Egypt from the medico-legal point of view and to determine factors that affect their mortality. The medical records of all patients admitted to the Burn Unit, Suez Canal University Hospital in the period between 1 st January 2013 and 31 st December 2014 were reviewed retrospectively. The total number was 292 patient, the mean age of patients was 17.5±17.2 years; children less than 5 years of age were more exposed to burn injuries (35.6%) than other age groups. Males constituted 68.1% of the study group, while 63% came from rural areas. Flame burns and scalds represented 48.2% and 44.9% respectively with a predominance of injuries in colder months. The majority of cases (72.6%) showed a percentage of total body surface area (TBSA) less than 20%. Upper extremities were most commonly affected (58.2%). A significant relationship was found between TBSA and each of: type of burn, duration of the hospital stay, ICU admission and outcome. A significant relation was also found between type of burn and each of: age, gender, and duration of hospital stay. Mortality rate was 5.5% of cases and septicemia was the most common cause of death (43.8%). Using stepwise logistic regression, TBSA and ICU admission were the only detected mortality predictors.
