Although many aspects of stroke are similar at both sexes, however, there are some differences and characteristics as well. The aim of this study was to analyze sex differences in patients with acute ischemic stroke (IS) regarding to risk factors, subtypes, stroke severity and outcome. From January 1st 2001 to December 31st 2005 at the Department of Neurology Tuzla 2833 patients were admitted with acute ischemic stroke (IS). We were analyzed risk factors, subtypes, stroke severity (Scandinavian Stroke Scale), and thirty-day outcome. There were 1484 (52.3%) female, and they were older than male (67.8 +/- 10.6 vs. 65.7 +/- 10.5, p<0.0001). Hypertension (78% vs. 67%, p<0.0001), heart diseases (50% vs. 45%, p=0.009), atrial fibrillation (22% vs. 14%, p<0.0001) and diabetes mellitus (33% vs. 21%, p<0.0001) were frequently in female, while smoking (45% vs. 14%) and alcohol overuse (18% vs. 0,6%) in male (p<0.0001). Atherothrombotic type of ischemic stroke was frequently in male (37.4% vs. 31.6%, p=0.0013) and cardioembolic in female (21.7% vs. 15.5%, p<0.0001). At admission female had lower SS (SS 31.0 +/- 15 vs. 34.0 +/- 15, p<0.0001). Thirty-day mortality was significantly higher in female (23.3% vs. 18.4%, p=0.0015), and favourable outcome within one month (Rankin Scale <or= 2) had 58% male and 51% female (p=0.001). The frequency of ischemic stroke is higher in female who are older than male. There are some sex differences according to the distribution of risk factors and subtypes of ischemic stroke. Stroke severity at admission, thirty-day mortality, and disability are higher in female.

Ischemic stroke (IS) is defined as rapid development (focal or global) of clinical signs of brain function disorder with symptoms lasting 24 hours or longer, or leading to death, without other clear causes except destruction of blood vessel.1 Anxiety does occur in patients with IS, but not in those with intracerebral hemorrhages.2 Astrom found symptoms of anxiety in 28% of patients in acute phase of stroke.3 The aim of this study was to analyze anxiety in patients within 48 hours (hyperacute and acute phase) and 15th day (subacute phase) after the IS in relation to gender and location of the lesion. PATIENTS AND METHODS

The aim of the study was to determine duration of delirium in patients with acute stroke according to sex, age, type and localization of lesion. We assessed delirium prospectively in a sample of 233 consecutive patients with an acute (< or =4 days) stroke using the Delirium Rating Scale (DRS-R-98) and Diagnostic and Statistical Manual of Mental Disorders (DSM IV). The average duration of delirium was 4 days in patients with ischemic stroke and 3 days in patients with hemorrhagic stroke. There was no statistically significant difference in delirium duration between these two patient groups. A longer duration of delirium was recorded in women and in patients older than 65. The period of delirium was longer in patients with right hemispheric lesions. Patients did not differ according to delirium duration, sex, age, type and localization of stroke. In two thirds of patients, the symptoms of delirium completely disappeared on medicamentous treatment, while in the remaining one third of patients certain symptoms of delirium persisted at discharge (p=0.003). Mortality rate was significantly higher in patients with delirium in the acute phase of stroke than in those without delirium (p=0.009). In conclusion, delirium is a temporary manifestation in two thirds of patients in the acute phase of stroke. Patient sex and age, and type and stroke localization have no influence on delirium duration.

Generally, Arnold – Chiari malformation associated with syringomyelia is not rare. In this case report we present a 52 years old female patient with a history of neck-pain, low-back pain, pain in both arms as well as frequent numbness in the lateral regions of both arms. She also experienced walk disturbance and in her previous history she reports a car accident, twenty-eight years ago. She broke windshield with her forehead, but remained conscious at the time. At the time of admittance at the Department of Neurology, her neurological status was remarkable for cerebellar symptomatology (ataxia, positive Romberg-sign, «finger–nose» test which she did with tremor and was not able to perform «tandem-walk»), hypoestesia of the right side of the body, hyper-reflection of both arms and legs, bilaterally, more pronounced at the right side; right foot subclonus and spastic-ataxic walk. Neurological status could not be explained by previously performed tests: x-ray of cervical spine, lumbal myelography, computerized tomography (CT) of the brain. However, magnetic resonance imaging (MRI) of the brain and cervical spine verified Arnold-Chiari malformation (type I) associated with syringomyelia from C3 to C7. Patient was referred to surgery and subsequent physical rehabilitation.

OBJECTIVE To analyze the frequency, gender and age distribution, risk factors, and hospital mortality of different types of hospitalized patients with stroke. METHODS In this retrospective study, we analyzed the hospital records of 3864 patients with first-ever stroke admitted to the Department of Neurology, University Clinical Center Tuzla, Bosnia and Herzegovina, from January 2001 to December 2005. RESULTS Out of the total number of patients, 2833 (73.3%) had ischemic stroke (IS) 612 (15.8%) intracerebral hemorrhage (ICH), 163 (4.2%) subarachnoid hemorrhage (SAH), and 256 (6.6%) had unknown stroke. The mean age was 68+/-10 years in females, and 65+/-11 years in males (p=0.000). Overall, there were 2045 (53%) women (p=0.000). Women suffered from cardioembolic stroke more than men (21.7% versus 15.6%, p=0.000), and men were more affected by atherothrombotic stroke (37.4% versus 31.6%, p=0.000). The leading stroke risk factors were hypertension (70%), heart diseases (40%), smoking (28%), and diabetes mellitus (21%). The total hospital mortality was 29.6%, and hospital mortality in patients with IS was 20.6%, ICH 43.8%, and SAH 26.4%. CONCLUSION Women are older than men in all types of stroke. The leading risk factors for both genders are hypertension and heart diseases. The hospital mortality rate is lower than 30%.

The objective of the study was to analyze the doppler sonography findings of vertebrobasilar circulation (VB) in patients with Parkinson's disease. 40 patients were analyzed (25 men's and 15 women) with Parkinson's disease, average age was 61.9 years (SD=11.43), treated at the Clinic for Neurology in Tuzla. Device for doppler sonography was Multidop x 4. Doppler sonography findings of VB circulation were analyzed in order to computerized tomography (CT) findings of the brain (with or without ischemic lacunar lesions) and in order to presence of postural disturbances as one of dominant Parkinson's disease symptoms during actual hospitalization. Our results suggest that vertebrobasilar insufficiency is more frequent in patients with Parkinson's disease (no matter of type) and postural disturbances as a dominant symptom comparing to group of Parkinson's disease patients without postural disturbances. These results implicate the importance of doppler sonography findings of vertebrobasilar circulation in patients with Parkinson's disease and possibility of considering role of vertebrobasilar insufficiency in development of postural disturbances.

Intracerebral hemorrhage is the deadliest, most disabling and least treatable form of stroke despite progression in medical science. The aim of the study was to analyze the frequency, risk factors, localization and 30-day prognosis in patients with intracerebral hemorrhage. We analyzed 352 patients with intracerebral hemorrhage (ICH) hospitalized at the Department of Neurology Tuzla during a three-year follow up. The following data were collected for all patients in a computerized database: age, sex, risk factors (hypertension, heart diseases, diabetes and smoking) and CT findings. Stroke severity was estimated with Scandinavian Stroke Scale, ICH topography was specified by CT, and outcome at 1st month after onset included information on vital status and disability (modified Rankin Scale, mRS). The most frequent risk factors were hypertension (84%), heart diseases (31%), cigarette smoking (28%) and diabetes mellitus (14%). The most frequent localization of ICH was multilobar (38%), internal capsule/basal ganglia region (36%) and lobar (17%). Within first month died 147 patients (42%). The highest mortality rate was in patients with brain stem (83%) and multilobar hemorrhage (64%). Factors independently associated with mortality were age (odds ratio 1,05 (95% confidence interval 1,02 to 1,08); p=0,001), stroke severity (OR 0,93 (0,92 to 0,95); p<0,0001), multilobar hemorrhage (OR 5,4 (3,0 to 9,6); p<0,0001) and intraventricular hemorrhage (OR 3,9 (2,2 to 7,1); p<0,0001). Favorable outcome at first month (mRS < or = 2) had 45% of the surviving patients with ICH. The best outcome was for the patients with cerebellar hemorrhage (63%), while only 40% of the patients with hemorrhage in internal capsule/basal ganglia region had Rankin scale 2 or less. Hypertension is the most frequent risk factor in patients with ICH. ICHs are mainly localized in lobar and internal capsule/basal ganglia regions. Independent predictors of mortality following ICH are age, hypertension, intraventricular blood extension and stroke severity. Mortality, as well as good outcome at 1 month, is related to the localization of bleeding.

The aim of this study was to analyze: frequency of balance disorder (vertigo and disequilibrium), frequency of abnormalities in auditory evoked potentials (AEP) and magnetic resonance imaging (MRI) changes of the brain in multiple sclerosis (MS) patients with balance disorder, relation of patient's disability status to balance disorder and relation of the changes in MRI of the brainstem to AEP abnormalities. It was analyzed 60 patients with relapsing-remitting form of MS. Two groups of patients were made consecutively under Expanded Disability Status Scale score (EDSS): A (EDSS < or =4,5) and B (EDSS > or =5,0). The study was retrospective-prospective. After the neurological exam AEP and MRI of the brain have been done. Balance disorder has been verified as initial symptom in 29 (48,4%) and out of them disequilibrium experienced 24 (83,4%) patients. During the relapses balance disorder experienced 48 (80%) patients and in 37 (77,1%) it was disequilibrium. Among them 33 (68,7%) were with lower EDSS (< or =4,5) and 15 (31,3%) with higher EDSS score (> or =5). There is no correlation between disability status and vertigo which means that vertigo is not more frequent in more disabled patients and vice-versa. The AEP were pathological in 57 (95%) patients. Of all 29 patients with vertigo AEP were pathological in 28 (96,5%) while in 31 patients without vertigo pathological AEP were in 29 (93,5%) but it is not statistical significant. The most frequent characteristic of AEP changes were prolonged inter-peak latency III-V waves (48 patients or 80%). The plaque in brainstem visualized by MRI was found in 41 (71,8%) of patients (38 or 92,6% of them had pathological AEP and in three patients AEP were normal). In group of patients with pathological AEP, 38 (66,6%) of them had plaque in brainstem. In other three patients with normal AEP it was visualized plaque in brainstem. In the group of 29 patients with balance disorder, 20 (68,9%) had plaque in brainstem as well as 21 (67,7%) out of 31 patients without balance disorder had plaque in the brainstem. This difference is not statistical significant. It is concluded that the vertigo (including disequilibrium) is relatively often (48,4%) initial symptom of MS. Vertigo is not more frequent in patients with higher EDSS score and vice-versa. Pathological AEP are frequent neurophysiologic finding in both (95%) patients with (96,5%) and without (93,5%) vertigo. The most often pathological characteristic of AEP are prolonged interpeak latency of III-V waves (78,5%), as well as abnormalities of V and than IV wave. MS plaques in brainstem visualized by MRI technique are frequent in both groups of patients with and without pathological finding of the AEP.
