Introduction: The great population of about 16 million students in our country and their health problems require more attention to the health of students. Students due to low age and consequently lack of adequate experience are exposed to various types of accidents in schools. Accidents are the leading cause of death in 5 to 17 year old children. The aim of this study was to determine the incid...

BACKGROUND The incidence of inflammatory bowel disease (IBD) varies among different societies. The aim of this study is to determine the incidence rate of IBD in Kerman, a city in Southeast Iran. METHODS All medical records that indicated a new diagnosis of ulcerative colitis (UC) or Crohn's disease (CD) were retrieved from the gastrointestinal endoscopy and pathology departments of 12 centers ...

Malignant mesothelioma is a malignant tumor on the pleura or the peritoneum caused mostly by asbestos. Although asbestos is not currently used in South Korea, the incidence of mesothelioma is increasing due to its long latent period. This study predicted the incidence of malignant mesothelioma in South Korea over the next 20 years using an age-period-cohort (APC) model. Data regarding mesotheli...

achieving a desirable percutaneous absorption of drug molecule is a major concern in formulating dermatological products. the use of penetration enhancers could provide a successful mean for this purpose. the aim of this study was to evaluate the effect of incorporating a few common penetration enhancers (in different concentrations) into a 0.5% w/w piroxicam (model drug) gel formulation, on th...

direct yaw moment control systems (dyc) can maintain the vehicle in the driver’s desired path by distributing the asymmetric longitudinal forces and the generation of the control yaw moment (cym). in order to achieve the superior control performance, intelligent usage of lateral forces is also required. the lateral wheel forces have an indirect effect on the cym and based upon their directions,...

OBJECTIVE To evaluate whether mortality and clinical outcomes vary for injured patients in a mature trauma system on weeknights and weekends compared with weekdays. DESIGN Retrospective cohort study. SETTING Pennsylvania trauma system. PATIENTS A total of 90,461 patients over 5 years. INTERVENTION Treatment at a level I, II, or III trauma center. MAIN OUTCOME MEASURES In-hospital mort...

OBJECTIVE The aims of this study were to update previous estimates of the congestive heart failure (CHF) incidence rate in patients with type 2 diabetes, compare it with an age- and sex-matched nondiabetic group, and describe risk factors for developing CHF in diabetic patients over 6 years of follow-up. RESEARCH DESIGN AND METHODS We performed a retrospective cohort study of 8,231 patients w...

Accurate cancer incidence data is needed to plan, monitor and evaluate national cancer control programs. In Japan, however, such information is not available due to low reporting rates to cancer registries. In order to have more accurate incidence estimation, we developed a new method. We obtained a nonlinear regression model between observed incidence/mortality (IM) ratios and death certificat...
