    One of the most important steps for preventing deaths due to snake bites is to administer snake antivenom to the eligible patients in a swift manner. In our study, we aimed to investigate whether procalcitonin is useful for predicting the clinical severity and the necessity of antivenom therapy at the early stages in patients presenting with snake bite. A total of 78 patients over the age of 18 who applied to the emergency department within the first 24 hours were included in this retrospective cross-sectional study. Age and sex of patients, severity of snake bites, total antivenom vials administered, observation periods and outcomes were recorded. Patients were graded according to their clinical severity after the snake bite. Procalcitonin, complete blood count and biochemical parameters of the patients were recorded. According to their clinical severity, the patients' grades were as follows: 21 (26.9%) patients were grade 0; 21 patients (26.9%) were grade 1; 16 patients (20.5%) were grade 2; and 20 patients (25.6%) were grade 3. Snake antivenom was administered to 57 (73.1%) patients. There was a statistically significant difference between procalcitonin levels of patients in respect to their grade (P < 0.001). Sensitivity and specificity of procalcitonin levels of 13.45 and above were 100% and 100% respectively, both for the need of antivenom administration and for the blister formation in the patients. According to our study, we believe that elevated procalcitonin levels should alert the clinicians for possible blister formation, higher clinical severity, and increased requirement for antivenom administration.

    The role of neopterine in the diagnosis of patients with acute pancreatitis on admission to the emergency department
    (2016) Karabulut, Keziban Ucar; Gul, Mehmet; Ucar, Yildiz; Erdem, Sami
    Purpose: There are difficulties observed in the diagnosis of acute pancreatitis in emergency departments due to its different clinical properties and the insufficiencies in the methods of diagnosis. Since there is no specific biochemical indicator, the diagnosis is made usually late or with difficulty. Neopterine is an enzyme secreted from the macrophages and is an indicator of cellular immunity activation. The aim of this study was to determine the role of neopterine in the early diagnosis of acute pancreatitis. Material and Methods: 39 patients, who had been hospitalized with the complaints of abdominal pain and diagnosed as acute pancreatitis via laboratory and screening methods, and 30 healthy controls were included in the study. Amylase, lipase, cholesterol and neopterine were measured in the patients' samples. The diagnoses were confirmed with abdominal ultrasound and computed tomography. Results: The neopterine values in patients with acute pancreatitis were significantly higher than those of the control group. Conclusion: Neopterine is an indicator which is elevated in certain inflammatory and autoimmune situations. We believe that it is important in the early diagnosis of acute pancreatitis. Further experimental and clinical studies should be conducted on the subject.
