Öğe Assessment of Patients with Intracerebral Hemorrhage or Hemorrhagic Transformation in the VENOST Study(Karger, 2021) Duman, Taskin; Yayla, Vildan; Uluduz, Derya; Goksu, Eylem Ozaydin; Yurekli, Vedat Ali; Genc, Hamit; Utku, UygarIntroduction: Cerebral venous and sinus thrombosis (CVST) may lead to cerebral edema and increased intracranial pressure; besides, ischemic or hemorrhagic lesions may develop. Intracerebral hemorrhages occur in approximately one-third of CVST patients. We assessed and compared the findings of the cerebral hemorrhage (CH) group and the CVST group. Materials and Methods: In the VENOST study, medical records of 1,193 patients with CVST, aged over 18 years, were obtained from 35 national stroke centers. Demographic characteristics, clinical symptoms, signs at the admission, radiological findings, etiologic factors, acute and maintenance treatment, and outcome results were reported. The number of involved sinuses or veins, localizations of thrombus, and lesions on CT and MRI scans were recorded. Results: CH was detected in the brain imaging of 241 (21.1%) patients, as hemorrhagic infarction in 198 patients and intracerebral hemorrhage in 43 patients. Gynecologic causes comprised the largest percentage (41.7%) of etiology and risk factors in the CVST group. In the CH group, headache associated with other neurological symptoms was more frequent. These neurological symptoms were epileptic seizures (46.9%), nausea and/or vomiting (36.5%), altered consciousness (36.5%), and focal neurological deficits (33.6%). mRS was >= 3 in 23.1% of the patients in the CH group. Discussion and Conclusion: CVST, an important cause of stroke in the young, should be monitored closely if the patients have additional symptoms of headache, multiple sinus involvement, and CH. Older age and parenchymal lesion, either hemorrhagic infarction or intracerebral hemorrhage, imply poor outcome.Öğe 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, BijenObjective 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).Öğe Cerebral Venous Sinus Thrombosis as a Rare Complication of Systemic Lupus Erythematosus: Subgroup Analysis of the VENOST Study(Elsevier, 2019) Duman, Taskin; Demirci, Seden; Uluduz, Derya; Kozak, Hasan Huseyin; Demir, Serkan; Misirli, Cemile Handan; Kucukoglu, HayriyeAim: Systemic lupus erythematosus (SLE) is an unusual risk factor for cerebral venous sinus thrombosis (CVST). As few CVST patients with SLE have been reported, little is known regarding its frequency as an underlying etiology, clinical characteristics, or long-term outcome. We evaluated a large cohort of CVST patients with SLE in a multicenter study of cerebral venous thrombosis, the VENOST study, and their clinical characteristics. Material and Method: Among the 1144 CVST patients in the VENOST cohort, patients diagnosed with SLE were studied. Their demographic and clinical characteristics, etiological risk factors, venous involvement status, and outcomes were recorded. Results: In total, 15 (1.31%) of 1144 CVST patients had SLE. The mean age of these patients was 39.9 +/- 12.1 years and 13 (86.7%) were female. Presenting symptoms included headache (73.3%), visual field defects (40.0%), and altered consciousness (26.7%). The main sinuses involved were the transverse (60.0%), sagittal (40.0%), and sigmoid (20.0%) sinuses. Parenchymal involvement was not seen in 73.3% of the patients. On the modified Rankin scale, 92.9% of the patients scored 0-1 at the 1-month follow-up and 90.9% scored 0-1 at the 1-year follow-up. Conclusions: SLE was found in 1.31% of the CVST patients, most frequently in young women. Headache was the most common symptom and the CVST onset was chronic in the majority of cases. The patient outcomes were favorable. CVST should be suspected in SLE patients, even in those with isolated chronic headache symptoms with or without other neurological findings.Öğe Cerebral Venous Sinus Thrombosis in Women: Subgroup Analysis of the VENOST Study(Hindawi Ltd, 2020) Uluduz, Derya; Sahin, Sevki; Duman, Taskin; Ozturk, Serefnur; Yayla, Vildan; Afsar, Nazire; Uzuner, NevzatBackground. 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.Öğe Characteristics of Isolated Headache patients in Cerebral Venous Sinus Thrombosis (CVST): The Results of VENOST - national survey(Springeropen, 2018) Uluduz, Derya; Yalin, Osman Ozgur; Duman, Taskin; Domac, Fusun Mayda; Ozturk, Serefnur; Yayla, Vildan; Karahan, Ali Yavuz[Abstract Not Available]Öğe Epileptic seizures in cerebral venous sinus thrombosis: Subgroup analysis of VENOST study(W B Saunders Co Ltd, 2020) Uluduz, Derya; Midi, Ipek; Duman, Taskin; Yayla, Vildan; Karahan, Ali Yavuz; Afsar, Nazire; Goksu, Eylem OzaydinPurpose: 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.Öğe Headache as the sole presenting symptom of cerebral venous sinuses thrombosis: Subgroup analysis of data from the VENOST study(Kare Publ, 2021) Duman, Taskin; Cinar, Nilgun; Uluduz, Derya; Domac, Fusun Mayda; Ozturk, Serefnur; Yayla, Vildan; Karahan, Ali YavuzObjectives: Headache is the most common complaint in cerebral venous sinus thrombosis (CVST) and it may sometimes be the only symptom in these patients. This retrospective and prospective study was an investigation of any differences in terms of clinical risk factors, radiological findings, or prognosis in patients with CVST who presented with isolated headache (IH) and cases with other concomitant findings (non-isolated headache [NIH]). Methods: A total of 1144 patients from a multicenter study of cerebral venous sinus thrombosis ( VENOST study) were enrolled in this research. The demographic, biochemical, clinical, and radiological aspects of 287 IH cases and 857 NIH cases were compared. Results: There were twice as many women as men in the study group. In the IH group, when gender distribution was evaluated by age group, no statistically significant difference was found. The onset of headache was frequently subacute and chronic in the IH group, but an acute onset was more common in the NIH group. Other neurological findings were observed in 29% of the IH group during follow-up. A previous history of deep, cerebral, or other venous thromboembolism was less common in the IH group than in the NIH group. Transverse sinus involvement was greater in the IH group, whereas sagittal sinus involvement was greater in the NIH group. The presence of a plasminogen activator inhibitor (PAI) mutation was significantly greater in the IH group. Conclusion: IH and CVST should be kept in mind if a patient has subacute or chronic headache. PAI, which has an important role in thrombolytic events, may be a risk factor in CVST. Detailed hematological investigations should be considered. Additional studies are needed.Öğe A Multicenter Study of 1144 Patients with Cerebral Venous Thrombosis: The VENOST Study(Elsevier, 2017) Duman, Taskin; Uluduz, Derya; Midi, Ipek; Bektas, Hesna; Kablan, Yuksel; Goksel, Basak K.; Milanlioglu, AyselBackground: 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.

Our objective was to analyze risk factors, clinical, imaging, and laboratory variables to predict functional outcome and death in this population. Methods: CVT registries from three referral centers from Pakistan, Turkey, and Mexico, recruiting prospective cases, were combined for CVT associated with pregnancy or puerperium. Datasets and variables were standardized. Demographic characteristics, presentation, risk factors, and functional outcomes in pregnancy/puerperium-related CVT were analyzed. Binary logistic regression was used to assess predictors of outcome. The main outcome was modified Rankin score >2 at 30 days and mortality at 30 days. Results: Five hundred fifty-three cases (median age 28 years [IQR 23-34]) of CVT associated with pregnancy and puerperium were included; 439 cases (79.4%) happened in the puerperium and 20.6% during pregnancy (53.5% occurred during the first trimester). Anemia (36.7%) and dehydration (22.9%) were the commonest obstetric risk factors identified. Predictors of poor outcome (mRS >2) were encephalopathy (OR 12.8, p < 0.001), cases from Mexican origin (OR 3.1, p = 0.004), fever/puerperal infection (OR 2.7, p = 0.02), and anemia (OR 2.2, p = 0.01). Cases from Mexican origin (OR 12.0, p = 0.003) and Encephalopathy (OR 7.7, p < 0.001), presented with the highest mortality association in the final adjusted model. Discussion/Conclusion: In CVT associated with pregnancy and puerperium, encephalopathy, fever/puerperal infection, and anemia are associated with bad functional outcomes, meanwhile encephalopathy and cases from Mexican origin with higher mortality in the acute (30-days) of CVT onset. Anemia and infection are potential reversible predictors of poor outcome that clinicians should be aware of in order to prevent poor outcomes in these patients.Öğe Sleep changes during prophylactic treatment of migraine(Wolters Kluwer Medknow Publications, 2015) Duman, Taskin; Dede, Ozlem H.; Uluduz, Derya; Seydaoglu, Gulsah; Okuyucu, Esra; Melek, IsmetAims: To assess sleep quality in patients with primary headaches before and after prophylactic treatment using a validated sleep-screening instrument. Materials and Methods: A total of 147 patients, including 63 tension type headache (TTH) and 84 migraine patients were included. Patients were examined in terms of frequency and severity of headaches and sleep quality before and 12 weeks after prophylactic treatment with either propranolol or amitriptyline. Results: Baseline Visual Analogue Score (VAS) in migraine patients was 7.99 +/- 1.39 compared with 6.86 +/- 1.50 in TTH group (P < 0.001). VAS score after the first month of treatment was 6.08 +/- 1.88 in migraine patients and 5.40 +/- 1.61 in TTH (P = 0.023). VAS scores decreased after the third month of treatment to 4.32 +/- 2.29 in migraine patients and 4.11 +/- 1.66 in TTH patients (P = 0.344). The decrease was significant for patients treated with amitriptyline but not for those with propranolol. Baseline Pittsburgh Sleep Quality (PSQI) scores were 5.93 +/- 2.43 in migraine patients and 6.71 +/- 2.39 in TTH patients. Poor quality of sleep (PSQI = 6) prior to prophylactic treatment was observed in 61.4% of migraine patients and in 77.7% of TTH patients. Comparison of PSQI scores before and 3 months following treatment showed significantly improved quality of sleep in all treatment groups; the greatest significance was detected in migraine patients with initial PSQI scores of = 6 and treated with amitriptyline (P < 0.001). Conclusions: Increased understanding of routine objective sleep measures in migraine patients is needed to clarify the nature of sleep disturbances associated with primary headaches. This may in turn lead to improvements in headache treatments.Öğe Two cases of primary stabbing headache(2016) Güntel, Murat; Hürdoğan, Özge; Uluduz, Derya; Duman, TaşkınPrimer saplanıcı baş ağrısı; saniyeler süren nadir ve şiddetli bir başağrısıdır. Ağrı özellikle trigeminal sinirin birinci dalı boyunca hissedilir ve günde bir veya birkaç günde bir gelen bir veya birkaç kez tekrarlayan saplanma atakları şeklinde ortaya çıkar. Primer saplanıcı başağrısı yıllardır bilinmekle birlikte tanı için klinisyenin sorgulaması gereklidir. Primer saplanıcı başağrısının tanısını koymada diğer olası nedenlerin dışlanması önemlidir. İndometazin klasik olarak ilk tedavi seçeneğidir ancak olguların %35'e yakını tedaviye direnç gösterir. Son yıllarda cyclooxygenase-2 inhibitörleri, gabapentin, nifedipine, parasetamol, ve melatonin tedavisinin etkinliğini destekleyen çalışmalar bildirilmektedir.Öğe Undifferentiated headache: broadening the approach to headache in children and adolescents, with supporting evidence from a nationwide school-based cross-sectional survey in Turkey(Bmc, 2018) Woeber, Christian; Wober-Bingol, Cicek; Uluduz, Derya; Aslan, Tuna Stefan; Uygunoglu, Ugur; Tufekci, Ahmet; Alp, Selen IlhanBackground: Headache is a leading disabler in adults worldwide. In children and adolescents, the same may be true but the evidence is much poorer. It is notable that published epidemiological studies of these age groups have largely ignored headaches not fulfilling any specific set of ICHD criteria, although such headaches appear to be common. A new approach to these is needed: here we introduce, and investigate, a diagnostic category termed undifferentiated headache (UdH), defined in young people as recurrent mild-intensity headache of <1 h's duration. Methods: We conducted a nationwide cross-sectional survey in 31 schools in six regions of Turkey selected by mixed convenience-based and purposive modified cluster-sampling. A validated, standardised self-completed structured questionnaire was administered by a physician-investigator to entire classes of pupils aged 6-17 years. Results: Of the identified sample of 7889 pupils, 7088 (89.8%) participated. The 1-year prevalence of UdH was 29.2%, of migraine (definite and probable) 26.7%, and of tension-type headache (TTH) (definite and probable) 12.9%. UdH differed with respect to almost all headache features and associated symptoms from both migraine and TTH. Burden of headache and use of acute medication were lower in UdH than in migraine and TTH. Headache yesterday was less common in UdH than migraine (OR 0.32; 95% CI 0.28-0.37) and TTH (OR 0.64; 95% CI 0.56-0.77). Quality of life (QoL) was better in UdH (33.6 +/- 5.2) than in migraine (30.3 +/- 5.6; p < 0.001) and TTH (32.4 +/- 5.3; p < 0.001), but worse than in pupils without headache (35.7 +/- 4.7; p < 0.001). Conclusions: This large nationwide study in Turkey of pupils aged 6-17 years has shown that many children and adolescents have a headache type that does not conform to existing accepted diagnostic criteria. This new diagnostic category of presumably still-evolving headache (undifferentiated headache) is common. UdH differs in almost all measurable respects from both migraine and TTH. Although characterised by mild headaches lasting < 1 h, UdH is associated with significant adverse impact on QoL. Longitudinal cohort studies are needed to evaluate the prognosis of UdH but, meanwhile, recognition of UdH and its distinction from migraine and TTH has implications for epidemiological studies, public-health policy and routine clinical practice.
