Yayın Are cerebrospinal fluid protein levels and plasma neutrophil/lymphocyte ratio associated with prognosis of Guillain BarrE syndrome?(PAGEPRESS PUBL, 2017) Sahin, Sevki; Cinar, Nilgun; Karsidag, SibelGuillain Barre syndrome (GBS) is a post-infectious acute autoimmune polyradiculopathy. Cerebrospinal fluid (CSF) total protein level and plasma neutrophil/lymphocyte ratio (NLR) are related with autoimmune response. We aimed to reach a prognostic indicator for GBS by using electrophysiological findings, protein level of CSF, and plasma NLR based on Medical Research Council (MRC) sum score data. Cases who met diagnostic criteria of GBS and followed at least six months were enrolled in the study. Nerve conduction study (NCS) and lumbar puncture were performed one week after symptom onset. Routine CSF findings and complete blood count were recorded. Plasma NLR was calculated as the ratio of neutrophil cell count to lymphocyte cell count. All patients received intravenous immunoglobulin. MRC sum scores were calculated on administration time (1(st)) and six months later (2(nd)) for evaluation of recovery. Mean values of baseline CSF protein level, NCS parameters and NLR were compared with mean scores of MRC1st and MRC(2n)d. Increased CSF protein levels showed negative correlation with MRC(2n)d scores but no correlation with NCS. Increased NLR levels were positively correlated with age, MRC2nd scores and NCS. Facial diplegia was observed in 42% of patients. A positive correlation was found between high level of NLR and MRC1st, and there was no relationship with MRC2nd. Regression analyses showed that only CSF protein level was an independent factor on both MRC1st and MRC2nd. A positive association was found between baseline data included young age high plasma NLR, low level of CSF protein and good prognosis in our study. Also a positive correlation was found between high level of NLR and baseline disability in GBS cases with facial diplegia. Calculation of NLR is an easy and inexpensive method. On the other hand it may be influenced by age and immunotherapy. Our results showed that CSF protein level is still a liable parameter for prognosis. NLR could be a candidate prognostic marker of GBS cases. Further investigations including more cases are needed.Yayın Attenuated lactate response to ischemic exercise in migraine(INT SCIENTIFIC LITERATURE, INC, 2010) Sahin, Sevki; Cinar, Nilgun; Aksungar, Fehime Benli; Ayalp, Sunay; Karsidag, SibelBackground: Although the pathogenesis of migraine still remains unclear, certain metabolic studies done on patients with migraine indicate possible deficits in mitochondrial activity. Previously, the forearm ischemic exercise test (FIT) has been used as a screening tool to evaluate mitochondrial dysfunction in metabolic myopathies. Material/Methods: We studied the response of migraine patients to exercise using the modified FIT and compared this to the responses in a healthy group. After baseline venous blood samples were drawn, a sphygmomanometer cuff placed around the upper arm was inflated to 30 mmHg above systolic blood pressure and the subject performed a maximal isometric contraction of the forearm flexors using a hand-grip dynamometer with a 9-contraction: 1-relaxation duty cycle for a total time of 60 seconds. Results: In migraine patients, attenuated lactate response after the FIT in the 1(st), 3(rd) and 5(th) minutes were significantly different when compared to the control group. Conclusions: Our results show that there may be defects in the anaerobic or proximal glycolytic pathways in migraine patients, evident in stressful situations. We also conclude that the FIT may be useful for research on migraine pathophysiology.Yayın Behcet's disease as a causative factor of cerebral venous sinus thrombosis: subgroup analysis of data from the VENOST study(OXFORD UNIV PRESS, 2019) Uluduz, Derya; Midi, Ipek; Duman, Taskin; Colakoglu, Sena; Tufekci, Ahmet; Bakar, Mustafa; Nazliel, Bijen; Tascilar, Nida; Goksan, Baki; Sungur, Mehmet Ali; Kozak, Hasan Huseyin; Demir, Serkan; Misirli, Cemile Handan; Kucukoglu, Hayriye; Cinar, Nilgun; Domac, Fusun Mayda; Ozturk, Serefnur; Yayla, Vildan; Karahan, Ali Yavuz; Afsar, Nazire; Goksu, Eylem Ozaydin; Mengulluoglu, Necdet; Aytac, Emrah; Yesilot, Nilufer; Ince, Birsen; Yalin, Ozgur Osman; Oruc, Serdar; Demirci, Seden; Senol, Mehmet Guney; Yilmaz, Arda; Gokce, Mustafa; Kusbeci, Ozge Yilmaz; Uzuner, Gulnur; Caglayan, Hale Zeynep Batur; Acikgoz, Mustafa; Zeydan, Burcu; Ozdag, Fatih; Baybas, Sevim; Ekmekci, Hakan; Cabalar, Murat; Yaman, Mehmet; Yurekli, Vedat Ali; Tekeli, Hakan; Genc, Hamit; Utku, Uygar; Tokuc, Firdevs Ezgi Ucan; Uzuner, Nevzat; Bektas, Hesna; Kablan, Yuksel; Goksel, Basak K.; Milanlioglu, Aysel; Orken, Dilek Necioglu; Aluclu, UfukObjective This study was performed to determine the rate of cerebral venous sinus thrombosis (CVST) among cases of Behcet's disease (BD) included in a multicentre study of cerebral venous sinus thrombosis (VENOST). Methods VENOST was a retrospective and prospective national multicentre observational study that included 1144 patients with CVST. The patients were classified according to aetiologic factors, time of CVST symptom onset, sinus involvement, treatment approach and prognosis. Results BD was shown to be a causative factor of CVST in 108 (9.4%) of 1144 patients. The mean age of patients in the BD group was 35.27 years and 68.5% were men, whereas in the non-BD CVST group, the mean age was 40.57 years and 28.3% were men (P < 0.001). Among the aetiologic factors for patients aged 18-36 years, BD was predominant for men, and puerperium was predominant for women. The onset of symptoms in the BD group was consistent with the subacute form. The transverse sinuses were the most common sites of thrombosis, followed by the superior sagittal sinuses. The most common symptom was headache (96.2%), followed by visual field defects (38%). Conclusions BD was found in 9.4% of patients in our VENOST series. Patients with BD were younger and showed a male predominance. The functional outcome of CVST in patients with BD was good; only 12% of patients presenting with cranial nerve involvement and altered consciousness at the beginning had a poor outcome (modified Rankin Score 2).Yayın A Case of Intracranial Hypotension after Horse Riding(KOREAN NEUROLOGICAL ASSOC, 2019) Karsidag, Sibel; Cinar, Nilgun; Sahin, Sevki; Ates, Miruna Florentina; Tabak, Necati Alp…Yayın Cerebral Venous Sinus Thrombosis in Women: Subgroup Analysis of the VENOST Study(Hindawi, 2020) Uluduz, Derya; Sahin, Sevki; Duman, Taskin; Ozturk, Serefnur; Yayla, Vildan; Afsar, Nazire; Uzuner, Nevzat; Midi, Ipek; Cinar, Nilgun; Sungur, Mehmet Ali; Domac, Fusun Mayda; Ince, Birsen; Goksan, Baki; Misirli, Cemile Handan; Bakar, Mustafa; Kozak, Hasan Huseyin; Colakoglu, Sena; Karahan, Ali Yavuz; Goksu, Eylem Ozaydin; Ozdag, Fatih; Senol, Mehmet Guney; Yurekli, Vedat Ali; Aluclu, Ufuk; Demir, Serkan; Kucukoglu, Hayriye; Oruc, Serdar; Yesilot, Nilufer; Nazliel, Bijen; Tokuc, Firdevs Ezgi Ucan; Bektas, Hesna; Aytac, Emrah; Gokce, Mustafa; Caglayan, Hale Zeynep Batur; Tufekci, Ahmet; Uzuner, Gulnur; Orken, Dilek Necioglu; Yalin, Osman Ozgur; Utku, Uygar; Yılmaz, Arda; Genc, Hamit; Cabalar, Murat; Milanlioglu, Aysel; Ekmekci, Hakan; Zeydan, Burcu; Baybas, Sevim; Kablan, Yuksel; Goksel, Basak Karakurum; Acikgoz, Mustafa; Kurucu, Hatice; Demirci, Seden; Gunes, TaskinBackground. Early diagnosis of cerebral venous sinus thrombosis (CVST) associated with reproductive health-related risk factors (RHRF) including pregnancy, puerperium, and oral contraceptive (OC) use can prevent severe neurological sequelae; thus, the symptoms must be documented in detail for each group.Methods. Out of 1144 patients with CVST, a total of 777 women were enrolled from a multicenter for the study of cerebral venous sinus thrombosis (VENOST). Demographic, biochemical, clinical, and radiological aspects were compared for 324 cases with RHRF and 453 cases without RHRF.Results. The mean age of the RHRF (-) group (43.2 +/- 13 years) was significantly higher than of the RHRF (+) group (34 +/- 9years). A previous history of deep venous thrombosis (3%), isolated cavernous sinus involvement (1%), cranial neuropathy (13%), comorbid malignancy (7%), and its disability scores after 12 months (9%) were significantly higher in the RHRF (-) group. The RHRF (+) group consisted of 44% cases of puerperium, 33% cases of OC users and 23% of pregnant women. The mean age was found to be higher in OC users (38 +/- 9years). A previous history of deep venous thrombosis was slightly higher in the pregnancy subgroup (4%). Epileptic seizures were more common in the puerperium group (44%).Conclusion. The results of our study indicate that the risk of CSVT increases parallel to age, OC use, and puerperium period. In addition, when considering the frequency of findings and symptoms, epileptic seizures in the puerperium subgroup of the RHRF (+) group and malignancies in the RHRF (-) group may accompany the CSVT. In daily practice, predicting these risks for the CSVT and early recognition of the symptoms will provide significant benefits to patients.Yayın Cognitive Assessment in Early Stage of Parkinson's Disease(LIPPINCOTT WILLIAMS & WILKINS, 2012) Cinar, Nilgun; Sahin, Sevki; Bozdemir, Meral; Okluoglu, Tugba; Batum, Kubra; Karsidag, Sibel…Yayın Complications of botulinum toxin application: differences between hemifacial spasm and post-facial palsy synkinesis(SPRINGER HEIDELBERG, 2014) Cakmak, M. Aysen; Sahin, Sevki; Cinar, Nilgun; Karsidag, Sibel…Yayın Correlation between leptin and pro-inflammatory cytokines in cortical contusion injury model(TURKISH ASSOC TRAUMA EMERGENCY SURGERY, 2011) Karaoglan, Alper; Akdemir, Osman; Cinar, Nilgun; Cal, Mehmet Alpay; Kelten, Bilal; Uzun, Hafize; Colak, AhmetBACKGROUND The present study aimed to investigate time-dependent changes in leptin concentrations in brain tissue following experimental traumatic brain injury and to examine the relationship with cytokines. METHODS After circular craniectomy, 33 male Wistar-albino rats were positioned on a stereotaxic frame and subjected to cortical contusion injury and then divided into 3 groups based on the depth of deformation as: 0 mm (sham controls, n=3), 1.5 mm (moderate injury, n=15) and 2.7 mm (severe injury, n=15). Animals were sacrificed on the 1st, 3rd and 5th days post-injury. RESULTS One day after moderate injury, interleukin-1 beta (IL-1 beta), IL-6, tumor necrosis factor-alpha (TNF-alpha), and leptin levels were found to be markedly increased in the brain tissue. On the 3rd and 5th days, the levels returned to the sham-control levels. Following severe injury, IL-1 beta, IL-6 and TNF-alpha levels increased in correlation after the 1st day and reached the sham-control levels on the same days. However, leptin tissue levels decreased on the 1st and 3rd days and normalized to the sham-control levels on the 5th day. CONCLUSION Our results showed that the release of leptin is decreased in the early stage of severe injury. Thus, leptin replacement may play an important role in therapy in cases with severe traumatic brain injury.Yayın Correlation between Nerve Conduction Study and CSF Protein Level in Acute and Chronic Demyelinating Polyradiculopathies(LIPPINCOTT WILLIAMS & WILKINS, 2013) Cinar, Nilgun; Sahin, Sevki; Batum, Kubra; Karsidag, Sibel…Yayın COULD APOMORPHINE BE AN EFFECTIVE TREATMENT OPTION FOR REFRACTORY TREMOR IN PARKINSON'S DISEASE? A PILOT STUDY(NOBEL ILAC, 2013) Cinar, Nilgun; Sahin, Sevki; Karsidag, SibelObjective: We aimed to evaluate the extent of the clinical efficacy of intermittent subcutaneous apomorphine in addition to oral treatment in patients with Idiopathic Parkinson's Disease experiencing serious, refractory tremor despite the use of optimal oral dopaminergic medication. Treatment response was assessed with the motor section of the Unified Parkinson's Disease rating scale (UPDRS). Tremor rigidity and bradykinesia were scored by using specific items of the UPDRS. Material and Method: The study group included 13 consecutive patients with Parkinson's disease who have refractory tremor Increasing doses of 1 mg, 2 mg, 4 mg subcutaneous apomorphine were used; peak improvement dose and UPDRS scores were determined after 30 minutes. The patients have used oral dopaminergic treatment plus subcutaneous apomorhine and they have been followed on weekly phone calls. The completion of the study was defined as the end of the 1st month. Finally, the UPDRS motor scores of the patients were compared to the basal scores. Results: Three patients dropped out due to side effects. The average reduction rate of total UPDRS, tremor, bradykinesia and rigidity scores were found as 20.6%, 38.5%, 30.1% and 16.6% respectively. At the end of the first month, tremor, bradykinesia and rigidity scores were statistically improved in comparison to those of the baseline. Conclusion: Subcutaneous apomorphine combined to oral dopaminergic medications may provide effective relief in serious and refractory rest tremor as well as bradykinesia and rigidity in selected Parkinson patients.Yayın Distinguishing age-related cognitive decline from dementias: A study based on machine learning algorithms(ELSEVIER SCI LTD, 2017) Er, Fusun; Iscen, Pinar; Sahin, Sevki; Cinar, Nilgun; Karsidag, Sibel; Goularas, DionysisBackground and aim: This study aims to examine the distinguishability of age-related cognitive decline (ARCD) from dementias based on some neurocognitive tests using machine learning. Materials and methods: 106 subjects were divided into four groups: ARCD (n = 30), probable Alzheimer's disease (AD) (n = 20), vascular dementia (VD) (n = 21) and amnestic mild cognitive impairment (MCI) (n = 35). The following tests were applied to all subjects: The Wechsler memory scale-revised, a clock drawing, the dual similarities, interpretation of proverbs, word fluency, the Stroop, the Boston naming (BNT), the Benton face recognition, a copying-drawings and Oktem verbal memory processes (0VMPT) tests. A multilayer perceptron, a support vector machine and a classification via regression with M5-model trees were employed for classification. Results: The pairwise classification results show that ARCD is completely separable from AD with a success rate of 100% and highly separable from MCI and VD with success rates of 95.4% and 86.30%, respectively. The neurocognitive tests with the higher merit values were O-VMPT recognition (ARCD vs. AD), 0VMPT total learning (ARCD vs. MCI) and semantic fluency, proverbs, Stroop interference and naming BNT (ARCD vs. VD). Conclusion: The findings show that machine learning can be successfully utilized for distinguishing ARCD from dementias based on neurocognitive tests. (C) 2017 Elsevier Ltd.

The aim of this study was to contribute to the differential diagnosis between Alzheimer disease (AD) and DPD by comparing the neurocognitive tests and hippocampal volume. Materials and Methods: Patients who met criteria of AD/DPD were enrolled in the study. All patients were assessed using the Wechsler Memory Scale (WMS), clock-drawing test, Stroop test, Benton Facial Recognition Test (BFRT), Boston Naming Test, Mini-Mental State Examination (MMSE), and Geriatric Depression Scale (GDS). Hippocampal volume was measured by importing the coronal T1-weighted magnetic resonance images to the Vitrea 2 workstation. Results: A significant difference was found between the AD and DPD groups on the WMS test, clock-drawing test, Stroop test, Boston Naming Test, MMSE, GDS, and left hippocampal volume. A significant correlation between BFRT and bilateral hippocampal volumes was found in the AD group. No correlation was found among parameters in DPD patients. Conclusions: Our results suggest that evaluation of facial recognition and left hippocampal volume may provide more reliable evidence for distinguishing DPD from AD. Further investigations combined with functional imaging techniques including more patients are needed. (C) 2017 The Author(s) Published by S. Karger AG, BaselYayın Effects of 4% Icodextrin on Experimental Spinal Epidural Fibrosis(TURKISH NEUROSURGICAL SOC, 2017) Karanci, Turker; Kelten, Bilal; Karaoglan, Alper; Cinar, Nilgun; Midi, Ahmet; Antar, Veysel; Akdemir, Hidayet; Yalcinkaya Kara, Zeynep MineAIM: The aim of this experimental study was to investigate whether spinal epidural 4% glucose polymer solution is effective in the prevention of postoperative' ibrosis. MATERIAL and METHODS: Twenty eight adult Wistar albino rats were randomly divided into two equal groups, including treatment and control. Both groups underwent L1 vertebral total laminectomy to expose the dura. Topical treatment group received 4% icodextrin. Four weeks later, epidural fibrosis was examined in both groups histologically, biochemically and macroscopically. RESULTS: Topical use of 4% icodextrin prevented significantly epidural fibrosis following the laminectomy operation. CONCLUSION: Topical 4% icodextrin application inhibits postoperative epidural fibrosis with various mechanisms and prevents adhesions by playing barrier role between tissue surfaces through flotation. Our study is first to present evidence of experimental epidural fibrosis prevention with 4% icodextrin.Yayın Effects of Anthropometric Factors on Nerve Conduction An Electrophysiologic Study of Feet(AMER PODIATRIC MED ASSOC, 2013) Cinar, Nilgun; Sahin, Sevki; Sahin, Mustafa; Okluoglu, Tugba; Karsidag, SibelBackground: Previous studies have shown that age, sex, and body mass index (BMI) affect the amplitude of sensory nerve action potentials (SNAPs), but the total effects of multiple factors and the most prominently affected nerves have not been elucidated. We systematically investigated the effects of these factors on motor and sensory nerves of the feet. Methods: The amplitude, latency, and conduction velocity of compound muscle action potential (CMAP), SNAP, and mixed nerve action potential (MNAP) of the posterior tibial, calcaneal, distal posterior tibial, medial and lateral plantar, and sural nerves were measured in 30 healthy individuals (60 feet). The effects of age, sex, height, and BMI on each nerve were estimated by correlation and linear regression analyses. Results: The amplitude of posterior tibial CMAP and distal posterior tibial MNAP decreased with BMI. The amplitude of medial plantar MNAP and sural SNAP decreased with height. The conduction velocity of calcaneal SNAP and distal posterior tibial and lateral plantar MNAP decreased with height and BMI. The conduction velocity of medial plantar MNAP decreased only with height. The latency of posterior tibial CMAP increased with age and height. The latency of lateral plantar CMAP and calcaneal SNAP increased with height. The latency of lateral plantar MNAP increased with BMI. Conclusions: The effects of age, sex, height, and BMI in foot nerve conduction studies are not identical. Height and BMI were shown to strongly affect motor, sensory, and mixed nerve conduction. Further investigations are needed. (J Am Podiatr Med Assoc 103(1): 43-49, 2013)Yayın Eye-related visual hallucinations: Consider 'Charles Bonnet syndrome'(ALL INDIA OPHTHALMOLOGICAL SOC, 2011) Cinar, Nilgun; Sahin, Sevki; Karsidag, SibelThe Charles Bonnet Syndrome (CBS) is typically characterized by visual hallucinations in elderly people without cognitive defects. This article presents the case of an 80-year-old male patient with a one-year history of visual hallucinations, secondary to glaucoma, in both eyes. Neither a dopamine agonist nor cholinesterase inhibitor therapy improved his symptoms. In this case, the hallucinations were gradually improved after administration of a GABAergic drug, pregabalin, for diabetic polyneuropathy. Placebo-controlled clinical trials would be needed to support this effect of pregabalin, as suggested by this association.Yayın Frequently Seen But Rarely Diagnosed: Musical Ear Syndrome(AVES, 2016) Cakmak, Mirac Aysen; Sahin, Sevki; Cinar, Nilgun; Karsidag, Sibel…Yayın Gender differences in older adults with chronic migraine in Turkey(WILEY, 2015) Ozge, Aynur; Uluduz, Derya; Selekler, Macit; Ozturk, Musa; Baykan, Betul; Cinar, Nilgun; Domac, Fusun M.; Zarifoglu, Mehmet; Inan, Levent E.; Akyol, Ali; Bolay, Hayrunnisa; Uzuner, Gulnur T.; Erdemoglu, Ali K.; Oksuz, Nevra; Temel, Gulhan O.Aim: Chronic migraine is a growing and disabling subtype of migraine with different risk factors and clinical features, even in older adults. We sought to define and differentiate clinical features of chronic migraine in older adults. We also aimed to compare major clinical features of chronic migraine in older adults with those in younger people of both sexes. Methods: We used electronic dataset (Turkish Headache Database) from 13 tertiary headache centers in Turkey. Electronic dataset included detailed headache-defining features according to ICHD-II criteria based on face-to-face interviews and examination by a headache specialist. Using statistical methods, clinical variables of chronic migraine in older adults were compared with those of younger adults. We included 915 patients with chronic migraine (mean age 43.80 +/- 13.95 years); 83.3% were females. In total, 301 patients (32.9%) with chronic migraine aged >50 years were compared with 614 patients aged <50 years. Results: There was no significant change in men with increasing age. However, duration of headache history, severity of attacks, previous histories of motion sickness and positive family history of headaches were significantly different in women with increasing age. Further sex-related differences have been shown in parameters such as attack duration, quality and associated nausea. Conclusion: Chronic migraine is an infrequent type of migraine and shows age-related changes in some phenotypic characteristics, such as severity of attacks, especially in women aged older than 50 years. Furthermore, positive family history of headaches and history of motion sickness increase the likelihood of developing chronic migraine in older women, indicating involvement of some gender-related, but as-yet unknown, genetic factors.Yayın Intramuscular Hematomas Caused by Anticoagulant Therapy: Is Advanced Age a Risk Factor?(GALENOS YAYINCILIK, 2010) Cinar, Nilgun; Sahin, Sevki; Karaoglan, Alper; Karsidag, SibelOral anticoagulant therapy (OAT) is very effective in the prevention of cerebral embolism, especially in certain cardiac diseases. Hematomas are the major complication of OAT. It may threaten the patient's life by bleeding into the vital structures. Herein, we describe four patients with hematomas in the psoas, quadriceps, pectoral, or rectus abdominis muscles accompanied by anemia during warfarin therapy for atrial fibrillation and artificial heart valves. Computed tomography and magnetic resonance imaging helped us establish a definitive diagnosis in each case. Our patients were three women and one man. Their international normalized ratios were within the therapeutic range during this period. They suffered from minor traumas, such as falls or a hit while taking warfarin therapy. All anticoagulation treatments were discontinued for approximately 1 week after the episode of bleeding. Although conservative management was sufficient for three patients, one patient had surgical decompression due to a rectus abdominis hematoma with retroperitoneal hemorrhage. There were no episodes of bleeding or other complications after starting oral anticoagulant therapy during the follow-up. The common aspects of our cases were older age and a history of minor trauma. As a result, we suggest that special attention needs to be paid to the patients under anticoagulant therapy, especially those at an advanced age, and to warn them avoid trauma.

The aim of the present study was to investigate changes in mitochondrial abundance in peripheral lymphocytes of early and late stage AD patients. We analysed levels of mitochondrial DNA (mtDNA) and mean fluorescence intensity (MFI) of the mitochondria- specific antibody 113-1 in CD4(+), CD8(+), CD19(+) and CD56(+ )peripheral lymphocytes of early and late stage AD by quantitative real-time PCR and flow cytometry, respectively. In early stage AD, the levels of mtDNA were significantly decreased in CD4(+), CD19(+) and CD56(+) peripheral lymphocytes while the MFI of 113-1 staining was significantly decreased in CD4(+) and CD19(+ )cells. Thus, CD4(+) and CD19(+) peripheral lymphocytes of early stage AD patients exhibit mitochondrial depletion, as seen both at the level of DNA and protein.Yayın A Multicenter Study of 1144 Patients with Cerebral Venous Thrombosis: The VENOST Study(ELSEVIER SCIENCE BV, 2017) Duman, Taskin; Uluduz, Derya; Midi, Ipek; Bektas, Hesna; Kablan, Yuksel; Goksel, Basak K.; Milanlioglu, Aysel; Orken, Dilek Necioglu; Aluclu, Ufuk; Colakoglu, Sena; Tufekci, Ahmet; Bakar, Mustafa; Nazliel, Bijen; Tascilar, Nida; Goksan, Baki; Kozak, Hasan Huseyin; Demir, Serkan; Misirli, Cemile Handan; Kucukoglu, Hayriye; Cinar, Nilgun; Domac, Fusun Mayda; Ozturk, Serefnur; Yayla, Vildan; Karahan, Ali Yavuz; Afsar, Nazire; Goksu, Eylem Ozaydin; Mengulluoglu, Necdet; Aytac, Emrah; Yesilot, Nilufer; Ince, Birsen; Yalin, Ozgur Osman; Oruc, Serdar; Demirci, Seden; Senol, Mehmet Guney; Yilmaz, Arda; Gokce, Mustafa; Kuspeci, Ozge Yilmaz; Uzuner, Gulnur; Caglayan, Hale Zeynep Batur; Acikgoz, Mustafa; Zeydan, Burcu; Ozdag, Fatih; Baybas, Sevim; Ekmekci, Hakan; Cabalar, Murat; Yaman, Mehmet; Yurekli, Vedat Ali; Tekeli, Hakan; Genc, Hamit; Utku, Uygar; Tokuc, Firdevs Ezgi Ucan; Uzuner, NevzatBackground: Based on a number of small observational studies, cerebral venous sinus thrombosis has diverse clinical and imaging features, risk factors, and variable outcome. In a large, multicenter cerebral venous thrombosis (VENOST) study, we sought to more precisely characterize the clinical characteristics of Caucasian patients. Methods: All data for the VENOST study were collected between the years 2000 and 2015 from the clinical follow-up files. Clinical and radiological characteristics, risk factors, and outcomes were compared in terms of age and sex distribution. Results: Among 1144 patients 68% were women, and in older age group (>50 years) male patients were more prevalent (16.6% versus 27.8%). The most frequent symptoms were headache (89.4%) and visual field defects (28.9%) in men, and headache (86.1%) and epileptic seizures (26.8%) in women. Gynecological factors comprised the largest group in women, in particular puerperium (18.3%). Prothrombotic conditions (26.4%), mainly methylenetetrahydrofolate reductase mutation (6.3%) and Factor V Leiden mutation (5.1%), were the most common etiologies in both genders. 8.1% of patients had infection-associated and 5.2% had malignancy-related etiology that was significantly higher in men and older age group. Parenchymal involvement constitutively hemorrhagic infarcts, malignancy, and older age was associated with higher Rankin score. Epileptic seizures had no effect on prognosis. Conclusions: Clinical and radiological findings were consistent with previous larger studies but predisposing factors were different with a higher incidence of puerperium. Oral contraceptive use was not a prevalent risk factor in our cohort. Malignancy, older age, and hemorrhagic infarcts had worse outcome. (c) 2017 National Stroke Association.
