    Prognostic Factors in Patients with Occipital Encephalocele
    (Karger, 2010) Kiymaz, Nejmi; Yilmaz, Nebi; Demir, Ismail; Keskin, Siddik
    Background: An encephalocele is a herniation of the brain and the meninges through a skull defect protruding towards the exterior. The condition is not rare when compared to spinal dysraphisms, but the worldwide incidence is not precisely known. The cases involving occipital encephaloceles which we have diagnosed in our clinic and the surgical approaches for this rare condition are presented herein. Methods: Thirty patients who were diagnosed with occipital encephaloceles and referred to our Neurosurgery Clinic at the Yuzuncu Yil University, Faculty of Medicine Research Hospital between 2000 and 2009 were enrolled in this study. The age of the patient, size of the sac, pathologies that accompanied the condition, and treatments applied were assessed. Results: In the present study, 30 patients (22 girls and 8 boys), whose ages varied between newborn and 14 months, were evaluated. The encephalocele sac was located in the occipital region in 27 patients (90%) and in the occipitocervical region in 3 patients (3%). Nine (30%) of the 30 patients died; 2 in the preoperative period, 2 in the postoperative early period (0-7 days) and 5 in the late postoperative period first week to 3 months). With the exception of the 2 patients who died preoperatively, surgery was performed on all of the patients. The mortality rate in our study was 29%. Conclusions: Our study demonstrated that factors which determine the prognosis of patients diagnosed with occipital encephaloceles include the size of the sac, the contents of the neural tissue, hydrocephaly, infections, and pathologies that accompany the condition. An occipital encephalocele is a congenital neurologic condition with an extremely high morbidity and mortality in spite of the treatments rendered pre- and postoperatively. Copyright (C) 2010 S.

    Seroepidemiological studies of equine herpesviruses 1 (EHV-1) and (EHV-4) infections in working horses from the eastern Turkey
    (Chartered Inst. of Building Services Engineers, 2010) Ataseven, Veysel Soydal; Bilge-Da?alp, Seval; Başaran, Zeynep; Keskin, Siddik
    The objective of this research was to determine the presence of equine herpesvirus types 1 (EHV-1) and 4 (EHV-4) antibodies in local horses from five provinces in the East Anatolia region of Turkey. Blood samples were collected from 405 non-vaccinated horses living in Van, Bitlis, Muş, Erzurum, and I?di{dotless}r, and were analyzed via a commercial enzyme-linked immunosorbent assay (ELISA). EHV-1- and EHV-4-specific antibodies were detected in 94 (23.2%) and 316 (78.0%) of the 405 tested sera, respectively. The seropositivity percentages for EHV-1-specific antibodies by province were as follows: 29.5% in Van, 6.1% in Bitlis, 5.1% in Muş, 24.0% in I?di{dotless}r, and 20.6% in Erzurum. EHV-4-specific antibodies were detected at levels of 87.2% in Van, 61.2% in Bitlis, 56.4% in Muş, 84.0% in I?di{dotless}r, and 52.9% in Erzurum. The present investigation demonstrated that EHV-1 and EHV4 infections were more prevalent in the indigenous horse population from five provinces in the East Anatolia region of Turkey. Also, this data on the high seropositivity of both infections in two provinces (Van and I?di{dotless}r) along the eastern border of Turkey may be also serve as a risk indicator for future introductions of some transboundary diseases via border trade.
