There are different types of crosswalks for pedestrians to cross the street and different methods of operation. Signalization can be used in the operation of at-grade and controlled crosswalk. In these crosswalks, signaling is activated by pedestrians pressing buttons placed on the crosswalks. In this type of crossing, pedestrians press the button to cross the road and the signaling system detects the request. Within a reasonable time, the system turns red for vehicles and green for pedestrians, allowing pedestrians to cross the street safely. However, these systems have some drawbacks. Various observation and data collection studies were carried out at the pilot pedestrian crossing on Atatürk Boulevard in Atakum district of Samsun province. In these studies, 227 pedestrians crossing the crosswalk and 791 vehicles stopped at red lights during the crossing of pedestrians were examined. As a result of the data obtained in line with pedestrian and driver behaviors, it is aimed to determine the operational problems in signalized crosswalk with pedestrian warning and to increase efficiency with the studies to be carried out.

Introduction. Using single anesthetic agent in endoscopic retrograde cholangiopancreatography (ERCP) may lead to inadequate analgesia and sedation. To achieve the adequate analgesia and sedation the single anesthetic agent doses must be increased which causes undesirable side effects. For avoiding high doses of single anesthetic agent nowadays combination with sedative agents is mostly a choice for analgesia and sedation for ERCP. Aim. The aim of this study is to investigate the effects of propofol alone, propofol + remifentanil, and propofol + fentanyl combinations on the total dose of propofol to be administered during ERCP and on the pain scores after the process. Materials and Method. This randomized study was performed with 90 patients (ASA I-II-III) ranging between 18 and 70 years of age who underwent sedation/analgesia for elective ERCP.The patients were administered only propofol (1.5mg/kg) in Group I, remifentanil (0.05 µg/kg) + propofol (1.5mg/kg) combination in Group II, and fentanyl (1 µg/kg) + propofol (1.5mg/kg) combination inGroup III. All the patients' sedation levels were assessed with the Ramsey Sedation Scale (RSS). Their recovery was assessed with the Aldrete and Numerical Rating Scale Score (NRS) at 10 min intervals. Results. The total doses of propofol administered to the patients in the three groups in this study were as follows: 375mg in Group I, 150mg in Group II, and 245mg in Group III. Conclusion. It was observed that, in the patients undergoing ERCP, administration of propofol in combination with an opioid provided effective and reliable sedation, reduced the total dose of propofol, increased the practitioner satisfaction, decreased the pain level, and provided hemodynamic stability compared to the administration of propofol alone.

Osseous metaplasia is a heterotopic bone formation and it is encountered rarely in the gastrointestinal tract, especially in benign lesions. Although its pathophysiology is not known clearly, there are several theories suggested. In this case report, we presented a case of bone formation in a rectal inflammatory polyp presenting with rectal bleeding in a 7-year-old girl. Therewithal, we reviewed the literature and summarized the subject of osseous metaplasia in colon polyps. We detected some similarities in the cases presented that suggest it might be a distinctive disease entity. Osseous metaplasia in colorectal polyps is extremely rare. To our knowledge, this is the eleventh reported case of osseous metaplasia in a rectal inflammatory polyp. Although osseous metaplasia in colon polyps has not a significant effect on both clinic and the prognosis, it can be confusing when encountered in microscopic examination. [ABSTRACT FROM AUTHOR]
