(Arnold, Hodder Headline Plc, 2002) Sahin, I; Onbasi, K; Sahin, H; Karakaya, C; Ustun, Y; Noyan, T
Objective: The aim of this study was to evaluate the prevalence of pancreatitis in cases of organophosphate (OP) poisonings admitted to Yuzuncu Yil University Teaching Hospital over an 18-month period. Materials and Methods: A total of 47 patients of acute poisoning with OP insecticides attended the Emergency Department of the Yuzuncu Yil Medical School Hospital, from May 1999 to December 2000, and were prospectively studied. Serum amylase and lipase levels were studied with colorimetric assay. Serum SGOT, SGPT, LDH, CPK, K levels, leukocyte count and total hospitalization days were also evaluated. Results: Four of 47 patients had obviously elevated amylase and lipase levels (amylase > 300 U/L, lipase > 60 U/L). Only two of the patients with amylase levels between 100 and 300 V/L had also elevated levels of lipase. None of the patients with normal amylase levels had elevated levels of lipase. A total of 12.76% was diagnosed as acute pancreatitis. Conclusion: Acute pancreatitis as a complication of OP intoxication is not a rare condition. In order to improve the outcome of OP poisoning, early diagnosis of acute pancreatitis is important and serum levels of amylase and lipase should be routinely considered carefully. In acute pancreatitis, serum levels of SGOT, SGPT, LDH and leukocyte counts may also be found to be elevated. However, serum K levels are only slightly decreased.
Raynaud's Phenomenon in a Healthy Turkish Population
(Springer London Ltd, 2005) Onbasi, K; Sahin, I; Onbasi, O; Üstün, Y; Koca, D
Raynaud's phenomenon (RP) is a vasospastic disease and is characterized by ischemia of the digits, nose, and ears. The vasospasm can be triggered by cold weather, cold water, or emotional stress and is followed by triphasic color changes. First white color (ischemia), then blue color (congestion and cyanosis), and finally red color change (reactive hyperemia) can be observed. The prevalence is reported to be between 0.5 and 20% in different studies and is dependent on genetic, occupational, and environmental factors. The purpose of our study was to determine the prevalence of RP in an eastern part of Turkey among healthy subjects. A total of 768 people were included in the study. This cross-sectional study was conducted between April 2003 and October 2003 at the University Hospital and at the State Hospital in Van, Turkey. The participants were interviewed and examined to diagnose RP and a questionnaire and color charts were used. Of these 768 patients, 25 women and 20 men were diagnosed to have RP. A female predominance (25/20) was observed. Their mean age was 24.78 +/- 5.71 years. The prevalence of RP was 5.9% in our study population.
