    Multifocal Ewing's sarcoma of the brain, calvarium, leptomeninges, spine and other bones in a child
    (Elsevier Sci Ltd, 2008) Guezel, Aslan; Tatli, Mehmet; Er, Uygur; Yimaz, Fahri; Bavbek, Murad
    Ewing's sarcoma (ES) is a malignant osseous neoplasm that mostly affects children and young male adults, and usually presents as a solitary bony lesion. Multifocal ES of the central nervous system is extremely rare, with an incidence ranging from 1.1% to 4.3%. Clinically, ES may mimic osteomyelitis. In this report, we describe the case of an 11-year-old boy who had multiple calvarial, leptomeningeal, spinal and various other bony lesions of ES, which were diagnosed radiologically and histopathologically. To the best of our knowledge, this is the first time that multiple brain, calvarial and spinal lesions of ES in a single patient have been reported in the English-language literature. We discuss possible mechanisms and differential diagnoses for this rare pathology. (C) 2007 Elsevier Ltd. All rights reserved.

    Predictive Factors for Acute Stress Disorder and Posttraumatic Stress Disorder after Motor Vehicle Accidents
    (Karger, 2009) Yasan, Aziz; Guezel, Aslan; Tamam, Yusuf; Ozkan, Mustafa
    Background: Since traffic accidents are more common in developing countries than in developed countries, we aimed to investigate the association of several factors with the development and persistence of posttraumatic stress disorder (PTSD) after traffic accidents. Sampling and Methods: In the study, 95 participants with injuries from traffic accidents were evaluated at 4 different times: in the beginning, and after 3, 6 and 12 months. Results: During the first evaluation, 41.1% (39) of our participants had acute stress disorder (ASD). It was found that lower perceived social support (OR = 0.0908, 95% Cl = 0.834-0.989, p = 0.027) and higher peritraumatic dissociative experience scores (OR = 1.332, 95% Cl = 1.170-1.516, p < 0.001) were significant predictors of ASD. In the evaluations after 3, 6 and 12 months after the accident, we found PTSD affected 29.8, 23.1 and 17.9% of the participants, respectively. Although limitations at work and in social life after a traffic accident were not related to PTSD at 3 months (OR = 122.43, 95% Cl = 0.000, p = 0.999) or at 6 months (OR = 63.438, 95% Cl = 0.529-76.059, p = 0.089), limitations at work and in social life were predictors of PTSD at 12 months (OR = 155.514, 95% Cl = 2.321-104.22, p = 0.019). Conclusions: The persistence of PTSD at the 12-month evaluation is related to ASD, limitations in work and social life, and lower social support scores. In developing countries like Turkey, long-term PTSD is commonly seen after traffic accidents. Copyright (C) 2009 S. Karger AG, Basel
