Introduction : Bone-related dimensions are more applicable for sex determination because these are not affected by the passages of time. We aimed to evaluate the value of frontal sinus parameters for gender identification. Materials and Methods: A cross-sectional study was performed on 159 cases. According to CT scan, three dimensions including maximum height of frontal sinus, maximum width of the sinus as well as the distance from the highest part to external border of the frontal sinus on both sides were measured. Data were analyzed by using the receiver operating characteristic (ROC) curve. Results: measuring the distance from the highest part to external border of the frontal sinus in both left and right sides for predicting gender [AUC (area under the curve) of 0.820 and 0.828, respectively]. Conclusions: Different diameters related to the frontal sinus can be used for gender identification among Iranian population. [ABSTRACT FROM AUTHOR]

There is little information regarding sexual abuse in children that might help identify those at a high risk of suicide. A ten-year-old boy was found dead while hanging himself in his room. Upon opening the door, his mother saw this scene. Crime scene investigation was performed for him, and her parents reported that the kid had no emotional instabilities or psychological problems. The first possible reason was that the suicide might have been caused by watching crime movies. Medico-legal examinations attributed the death to suicide. The signs of anal rape (new trauma) were observed in the dead body. Evidence suggested that he had hanged himself after being abused. Suicidal ideation should be seriously considered. Detailed forensic examinations could exactly determine the cause of crime. [ABSTRACT FROM AUTHOR]
