Background: 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 ± 9 years). 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 ± 9 years). 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., Competing Interests: The authors declared that they have no conflicts of interest for this article., (Copyright © 2020 Derya Uluduz et al.)

Purpose: The aim of this study is to evaluate the presence and prognostic impact of early seizures in cerebral venous sinus thrombosis patients (CVST)., Method: VENOST is a retrospective and prospective national multicenter observational study. CVST patients with or without epileptic seizures (ES) were analyzed and compared in terms of demographic and imaging data, causative factors, clinical variables, and prognosis in a total of 1126 patients., Results: The mean age of the patients in the ES group was 39.73 ± 12.64 and 40.17 ± 14.02 years in the non-ES group (p > 0.05). Epileptic seizures were more common (76.6 %) in females (p < 0.001). Early ES occurred in 269 of 1126 patients (23.9 %). Epileptic seizures mainly presented in the acute phase (71.4 %) of the disease (p < 0.001). Majority of these (60.5 %) were in the first 24 h of the CVST. The most common neurological signs were focal neurologic deficits (29.9 %) and altered consciousness (31.4 %) in the ES group. Superior sagittal sinus (SSS) and cortical veins (CV) involvement were the most common sites of thrombosis and the mostly related etiology were found puerperium in seizure group (30.3 % vs 13.9 %). Patients with seizures had worse outcome in the first month of the disease (p < 0.001) but these did not have any influence thereafter., Conclusions: In this largest CVST cohort (VENOST) reported female sex, presence of focal neurological deficits and altered consciousness, thrombosis of the SSS and CVs, hemorrhagic infarction were risk factors for ES occurrence in patients with CVST., Competing Interests: Declaration of Competing Interest The authors have no conflict of interest to disclose., (Copyright © 2020.

Objective: This study was performed to determine the rate of cerebral venous sinus thrombosis (CVST) among cases of Behçet'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)., (© The Author(s) 2018.

Background: 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., (Copyright © 2017 National Stroke Association.

Background and Purpose: Stroke, which remains the third leading cause of death after heart disease and cancer in developed countries, is a disorder causing permanent neurologic disability. Even though, hemorrhagic strokes are seen less than the ischemic type, they are more fatal. We studied the risk factors for spontaneous intra-cerebral hemorrhage (ICH) to direct the proper preventive treatment modalities and the effects of these factors on mortality as well as applied therapeutic strategies on survival., Materials and Methods: The archive records of 106 patients (60 male, 46 female) who were diagnosed with spontaneous ICH in Baskent University Hospital, Ankara, between January 2003 and September 2008, were assessed retrospectively., Results: The mean age was found as 62.5. The most frequent risk factor was hypertension (73.5%); 69.2% of these hypertensive patients had uncontrolled blood pressure levels. The mortality rate was detected as 34.9% and patients were found to die approximately within 9 days after ICH. Older age, increased hemorrhage volume, ventricular extension of hemorrhage, and the presence of midline shift were found to significantly correlate with increased mortality (P < 0.05). Patients who underwent surgical therapy showed a longer survival rate (P = 0.016); however, no association was found between medical and surgical therapy in terms of mortality (P = 0.555)., Conclusion: The results of this study suggest that effective control of blood pressure is important in the prevention of spontaneous ICH; clinical and radiological findings with treatment modalities influencing mortality should be carefully managed.

Spontaneous intracranial hypotension is characterized by postural headache that is generally associated with neck and/or back pain, radicular symptoms, nausea, and vomiting, and can sometimes be accompanied by cranial nerve symptoms. Although ocular manifestations are common, visual impairment due to optic nerve involvement is not commonly reported. Here, we report a case of a 34-year-old woman with postural headache and visual loss in the left eye associated with spontaneous intracranial hypotension. The orbital magnetic resonance imaging revealed increased intensity on T2-weighted images and on the pathologic contrast enhancement of the left optic nerve. Radionuclide cisternography showed bilateral cerebrospinal fluid leakage at the top of the thoracic region. To our knowledge, this is the first report documenting an association between optic neuropathy and spontaneous intracranial hypotension.

Aim: Primary intraventricular hemorrhage (PIVH), bleeding in the ventricular system without a recognizable parenchymal component, is a rare neurological disorder. The purpose of this study was to identify clinical features, risk factors, etiology and outcome of patients with PIVH., Material and Methods: We retrospectively reviewed the clinical data, complementary examinations, outcome and computed tomography (CT) IVH score of 24 patients in our hospital from 2004 to 2008. We identified 24 patients with the inclusion criteria of non-traumatic PIVH. Their mean age was 60.6+/-17.4 years (range 38-79). Fourteen patients were male and 10 were female., Results: The major symptoms included headache (n=24), loss of consciousness (n=6), confusion and disorientation (n=14), nausea/vomiting (n=10). Angiography revealed vascular malformations in five patients (21%). Other possible causative factors were hypertension in 12 patients (50%) and clotting disorder in one. The aetiology remained unknown in six patients. Most PIVH patients had associated hydrocephalus (58%) and 37% of the patients required ventricular drainage. In-hospital mortality was high (41%) and a FOUR score

Objective: The aim of this study was to evaluate the prevalence, demographic, clinical features, and possible risk factors for hemodialysis headache (HDH)., Background: HDH has been recognized for many years, but the pathophysiology of this condition is not known. High arterial blood pressure, decreased serum osmolality, sodium washout, and high blood urea nitrogen level are reported risk factors for HDH. Low serum magnesium (Mg) level is known to cause some types of headache, including migraine (menstrual migraine in particular), tension-type headaches, and cluster and posttraumatic headaches. Low Mg has also been reported in HDH patients., Methods: A total of 250 hemodialysis (HD) patients were questioned about problems with headache. Of these, 75 were diagnosed with HDH according to the revised International Headache Society criteria for 2003. Eighty age- and sex-matched HD patients without HDH were selected as a control group. For each HDH and control subject, arterial diastolic and systolic blood pressure, body weight, and serum levels of sodium, blood urea nitrogen, creatinine, and Mg were measured before and after one HD session. Urea reduction rate and ultrafiltration were determined. Serum levels of phosphorus, calcium, albumin, and parathormone were measured only before the session. Findings in the HDH and control group were statistically compared., Results: As noted, 75 (30%) of the total 250 HD patients surveyed were diagnosed with HDH. The mean headache duration in this group was 5.17 +/- 5 hours. Vertex location, bilateral headache, dull nature, and moderate severity were the most prevalent features of HDH. There were no statistically significant differences between the HDH and control groups with respect to causes of end-stage renal disease. There were no significant differences between the HDH and control groups with respect to predialysis values for blood urea nitrogen, body weight, and arterial blood pressure (P > .05), and the same was true for comparisons of the postdialysis values for these parameters. The mean predialysis sodium level in the HDH group was higher than in the control group (P= .003). Both the mean predialysis and mean postdialysis Mg levels in the HDH group were significantly lower than the corresponding levels in the control group (P= .05 and P= .02, respectively)., Conclusions: The results suggest that low blood Mg level and high blood sodium level may be risk factors for HDH. Magnesium supplementation may help patients with HDH whose serum Mg levels are found to be low.
