Öğe Association Between Carpal Tunnel Syndrome and Abdominal Obesity(Turkish Neurological Soc, 2010) Uzar, Ertugrul; Ilhan, Atilla; Ersoy, AlevtinaObjective: Obesity has been suggested as a risk factor for carpal tunnel syndrome (CTS). Previous studies on the association of CTS and obesity have generally considered body mass index (BMI). However, the relationships between CTS and waist circumference or waist-to-hip ratio (WHR), which are known as more sensitive measures for abdominal obesity, have not been studied previously. In this study, it was aimed to evaluate the role of BMI and abdominal obesity in patients with CTS. Materials and Methods: Female patients who applied to the neurology outpatient clinics with pain, numbness, paresthesia, or dysesthesia in the hands were included. The patients were divided into two groups, according to the clinical evaluation, as CTS or non-CTS. CTS diagnosis was electrophysiologically confirmed in 44 patients. Thirty-one subjects who were not diagnosed as CTS electrophysiologically were recruited as the control group. Clinical findings, nerve conduction studies and anthropometric measurements (height, weight, BMI, hip circumference, waist circumference and WHR) of CTS patients were compared with those of the control group. Results: The CTS group had significantly higher BMI, waist circumference and WHR values compared to the control group (for each parameter, p< 0.0001). The rates of obesity in the CTS group were 55.8%, 47.7% and 34.9%, respectively, according to waist circumference, BMI and WHR measurements. In the CTS group, 16% of the patients, who were defined as non-obese according to BMI, were determined as obese according to waist circumference. In the CTS group, significant positive correlations were found between BMI and WHR and median-ulnar sensory interpeak latency of the fourth digit (r= 0.26, p< 0.05; r= 0.25, p< 0.05, respectively). Conclusion: In this study, it was found that abdominal obesity is an important risk factor for CTS, and nerve conduction may be affected by waist circumference, BMI and WHR. In addition to general obesity, abdominal obesity may be an important risk factor for CTS.Öğe Cryptogenic Isolated Cortical Venous Infarct: A Report of Three Cases(Galenos Publ House, 2011) Uzar, Ertugrul; Ilhan, Atilla; Cakir, Banu; Ersoy, Alevtina; Duzgun, Ulkuhan; Uz, BurakCortical vein infarction without dural sinus involvement is extremely rare. Herein, we present three patients with headache, partial seizure and right-sided numbness. On neurological examination, focal neurologic deficit was not observed in our patients. Magnetic resonance imaging revealed cerebral ischemia which showed as hypointense on T1-weighted images and hyperintense on T2-weighted images that do not follow the boundary of arterial territories, indicating cortical venous infarct. Cortical venous infarct should be suspected in patients who present with sudden onset headache and/or focal epileptic seizures even if there is no neurologic deficit. The diagnosis and treatment of cortical venous infarct should be considered as an emergency because of the high potential for full recovery with anticoagulant treatment.Öğe The increase of mean platelet volume in patients with Alzheimer disease(Tubitak Scientific & Technological Research Council Turkey, 2014) Koc, Emine Rabia; Uzar, Ertugrul; Cirak, Yasemin; Parlak Demir, Yasemin; Ilhan, AtillaBackground/aim: Vascular risk factors play an important role in the progression of Alzheimer disease (AD). Mean platelet volume (MPV) is a determinant of platelet functionality and increased MPV is associated with an increased risk of vascular inflammation. Here we aimed to examine whether MPV could be used as a marker of vascular damage in AD and to discuss the relation between MPV and other vascular risk factors. Materials and methods: A total of 109 outpatients with AD and 81 healthy controls were included in this study. Diagnosis of AD was made according to defined criteria. The Turkish version of the Mini Mental State Examination (MMSE) was used for cognitive assessment. According to the test results, patients were divided into 2 subgroups, mild (MMSE >= 18) and moderate (MMSE < 18), and their MPV levels were compared. Results: MPV levels were higher in the AD group. There was no statistically significant difference between the moderate group and the mild group according to MPV values. Conclusion: Increased MPV in patients with AD may point to platelet dysfunction. MPV is an indicator of increased in vivo platelet activation. Hence, platelets could be the link between vascular risk factors and AD. The assessment of MPV in patients with AD may help identify the patients that could benefit from additional antiplatelet therapy.Öğe PLATELET ACTIVATION IN ALZHEIMER'S DISEASE(Elsevier Science Inc, 2014) Koc, Emine R.; Uzar, Ertugrul; Cirak, Yasemin; Demir, Yasemin P.; Ilhan, Atilla[Abstract Not Available]
