Headache as the sole presenting symptom of cerebral venous sinuses thrombosis: Subgroup analysis of data from the VENOST study.

OBJECTIVES: 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.

Assessment of Patients with Intracerebral Hemorrhage or Hemorrhagic Transformation in the VENOST Study.

INTRODUCTION: 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.

Cerebral Venous Sinus Thrombosis in Women: Subgroup Analysis of the VENOST Study.

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.

The Review of Transient Ischemic Attack Patients: An Experience of a Clinic about Diagnosis and Follow-up.

OBJECTIVES: Transient Ischemic Attack (TIA) is due to a temporary lack of adequate blood and oxygen to the brain. TIAs typically last less than 24 hours. 10-15% of ischemic stroke patients have a history of TIA. 18% of them experience an ischemic stroke within 90 days, and the ABCD2 scoring system is used to estimate the risk. Our study aims to investigate the risk factors, the etiology, the lesion occurrence on MRI and the near-term risk of stroke of patients on whom TIA was diagnosed. METHODS: In this study, 124 patients were included between January 2012 and January 2018. Sixty-eight of the 124 patients were male. The history of patients was questioned; systemic and neurological examinations were made. The stroke risk factors and TIA duration were noted and ABCD2 scores were calculated. All the patients' blood samples, including glucose and lipid profile, were studied. They received CT, DWI MRI, electrocardiography, transthoracic echocardiography, ultrasound and/or MR angiography of the cervical arteries. RESULTS: One hundred twenty-four patients were included in this study, and 56 patients were female. The mean age was 63.04±16.77. Hypertension was the most common risk factor (50.8%). Twenty-seven patients were on antithrombotic; six patients were on anticoagulant therapy, while 91 patients were not receiving any antiaggregan therapy. ABCD2 scores were significantly higher on the antithrombotic therapy group (p=0.019). In 52 patients ABCD2 score was below 4, and in 72 patients, the score was greater than 4. In 67.7% of patients, no etiology was found. An ischemic lesion was detected in 16.9% of the patients. 58 % of the patients were discharged on anticoagulant therapy. Five patients developed ischemic stroke. CONCLUSION: The risk factors of ischemic stroke and TIAs are similar factors. The etiology of TIAs cannot be found out in most of the patients. Thus, the patients are discharged with oral anticoagulant treatment.

Cerebral Venous Sinus Thrombosis as a Rare Complication of Systemic Lupus Erythematosus: Subgroup Analysis of the VENOST Study.

AIM: 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.

Behçet's disease as a causative factor of cerebral venous sinus thrombosis: subgroup analysis of data from the VENOST study.

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).

Physical Activity Level of Ambulatory Stroke Patients: Is it Related to Neuropsychological Factors?

INTRODUCTION: Physical inactivity is an important risk factor for stroke and stroke recurrence. There is insufficient knowledge about the physical activity (PA) level in stroke patients who are ambulatory in the subacute phase. Our aim was to compare the PA level between ambulatory stroke patients and a population of the same age and to investigate neuropsychological factors that could affect the PA level in the same stroke group. METHODS: Eighty-five subacute stroke patients and 58 healthy subjects were included. Patients' demographic features, disease-related features, and comorbidities were recorded. The PA level was assessed by the International Physical Activity Questionnaire-Short Version and a pedometer (OMRON Walking style II). The Apathy Rating Scale was applied to determine the apathy level. Depression level was investigated by the Geriatric Depression Scale. The standardized Mini-mental State Examination was performed to assess the cognitive status. RESULTS: The PA level was significantly higher in the healthy group than in the stroke group (p<0.001). Step count and walking distance were significantly higher in healthy group (p=0.001 and p=0.04, respectively). The PA level of men was significantly higher than that of women (p=0.03). Participants who were classified as level 4 had a lower PA level than those who were classified as level 5 according to the Functional Ambulation Category. There was no relationship between the PA level and the apathy, cognitive, and depression levels in the stroke patients (p>0.05). CONCLUSION: Subacute stroke patients have a lower PA level than healthy subjects. This is not related to neuropsychological factors. The reasons for minor deficits related to ambulation should be researched further while developing strategies for increasing the PA level of subacute stroke patients.

Chronic manganese toxicity due to substance abuse in Turkish patients.

BACKGROUND: Manganese toxicity may lead to a levodopa-resistant akinetic-rigid syndrome. Pathological changes occur mostly in the pallidium and stratium. MATERIALS AND METHODS: We report seven patients with a new form of chronic manganese toxicity due to long-term intravenous use of a solution consisting of ephedrine, acetylsalicylic acid and potassium permanganate as a psycho-stimulant, popularly known as "Russian Cocktail". RESULTS: The age of the patients ranged between 19 and 31 years, and the duration of substance abuse was between nine and 106 months. The onset of symptoms from first use ranged seven to 35 months. The initial symptom was impaired speech followed by gait disturbance and bradykinesia. In addition to these symptoms, choreic movements, ataxia presenting as backward falls and dystonia were also seen. Serum and urine samples revealed high levels of manganese. Hyperintense lesions on T1-weighted magnetic resonance imaging were seen in bilateral basal ganglia and brainstem, dentate nuclei, features consistent with manganese intoxication. CONCLUSION: Manganese toxicity, which may cause a distinctive irreversible neurodegenerative disorder, can be seen frequently with "Russian Cocktail" abuse, a substance which can be accessed very easily and at a low cost.

Clinical and echocardiographic risk factors for embolization in the presence of left atrial thrombus.

AIMS: The aim of our study was to evaluate the factors leading to embolization in patients with left atrial thrombi (LAT). With this purpose, we retrospectively analyzed clinical, transthoracic, transesophageal echocardiographic data of patients with LAT in the transesophageal echocardiographic evaluation. METHODS AND RESULTS: One hundred ninety-two patients with LAT not on anticoagulant therapy were divided into two groups according to the presence of prior ischemic stroke. The group with ischemic stroke included more patients with sinus rhythm and less patients with mitral stenosis. They had smaller left atrial diameter, more left atrial appendage spontaneous echo-contrast, higher appendage ejection fraction, and emptying velocity. CONCLUSION: Once the thrombus has been formed, cerebral embolization seems to be higher in patients with relatively preserved appendage ejection fraction and emptying velocity. Presence of atrial appendage spontaneous echo-contrast also favor embolization. Factors leading to embolization seem to differ in some respects from the causes of thrombus formation.
