Terminal ileal perforation should be suspected in all cases of peritonitis especially in developing countries and surgical treatment should be optimized taking various accounts like etiology, delay in surgery and operative findings into consideration to reduce the incidence of deadly complications like fecal fistula.

Background: Computerized tomography scan (CT scan) can be useful for the measuring the calvarial thickness in human beings. This could help in identifying the racial and the gender variations in calvarial thickness in a population. The data obtained about calvarial thickness study in human population may be useful for researchers, anatomists, anthropologists, surgeons and manufacturers of surgical screws.Methods: This was an observational study carried out on 104 subjects, with a normal computerized tomography CT scan of the head. Any subject with a skull fractures or an underlying intracranial lesion were excluded from study. A total of 52 males and 52 females who presented in the radiology department for CT head were studied in a consecutive manner. The thickness of skull bone was measured on console (Somatom, Siemens 16 slice).Results: Our study population consisted of 52 male and 52 female subjects. The mean age for males was 48.03 (Range 18-70) years and while as the mean age of females was 47.37 (Range 18-73) years. We did not find any difference in the thickness of the frontal bone at upper third, middle third and lower third between the two sexes. However, the posterior third parietal bone, the anterior and middle third occipital bone was significantly thicker in females when compared to males.Conclusions: Our study suggests that the anterior third of the parietal bone has a more calvarial thickness on the right side than on the left side in both males and females. However, the female calvarium has a significantly thicker calvarium at the posterior third parietal; anterior and middle third occipital bones when compared to male counterparts showing a sexual dimorphism in our study population.
