    The importance of endoscopy in the diagnosis of small intestinal tumors was evaluated in 15 patients with small intestinal tumors treated in our hospital. Two tumors were benign, and 13 were malignant (carcinoma in 5 patients, malignant lymphoma in 5 and leiomyosarcoma in 3). The presence of lesions could be determined by X-rays before surgery, but definitive diagnoses were difficult. When preoperative endoscopy of the small intestine was possible accurate preoperative diagnoses could be made based on the endoscopic findings and biopsies taken under direct vision. Endoscopy is therefore very important for the diagnosis of small intestinal tumors. It is necessary to develop small intestinal endoscopes that are easier to insert

    Background and Objectives: To preventing deaths, it is essential to recognize factors affecting the survival of road accident victims. This study was conducted to identify the factors affecting the mortality of road accident victims.   Methods: All pre-emergency mission forms and hospital records of road accident victims were analyzed. The dependent variable was the time interval between the accident and death or discharge from hospital. The forms included demographic variables, accident location, injury status, type of vehicle, type of trauma, mission time, and vital signs.   Results: Of 8920 injured persons, death occurred in 143 (95% CI: 0.014-0.019). Being over 65 years (Hazard Ratio (HR) 7.6, 95% CI: 3.14-18.4), accident on the main roads (HR 1.44, 95% CI: 0.6-3.5), tracheal intubation (HR 26.4, 95% CI: 3.05-227.6), a systolic and diastolic blood pressure above 100 (HR 0.4, 95% CI: 0.4-0.12) and 70 mm Hg (HR 0.53, 95% CI: 0.24-1.2), and heart rate>100/min (HR 3.0, 95% CI: 1.7-5.1) were associated with the risk of death.   Conclusion: In providing services, age, status of blood pressure, pulse, injury status, and type of trauma can affect the patients’ survival
