Risk Factors in Acute Stroke Patients With and Without Sleep Apnea.

BACKGROUND: More than 50% of stroke patients have sleep-disordered breathing (SDB), mostly in the form of obstructive sleep apnea (OSA). SDB represents both a risk factor and a consequence of stroke. The presence of SDB has been linked with the poorer long-term outcome and increased long-term stroke mortality. About 20 to 40% of stroke patients have sleep-wake disorders (SWD), mostly in form of insomnia, excessive daytime sleepiness/fatigue, or hypersomnia (increased sleep needs). OBJECTIVE: The aim of this study was to analyze the frequency of risk factors in patients with acute stroke and sleep apnea. METHODS: The study included patients without cognitive impairment or with mild cognitive impairment. The diagnosis of apnea syndrome was made on the basis of the Snoring and Apnea Syndrome Questionnaire, the Epworth Sleep Scale, the Berlin Questionnaire, the Stanford Sleepiness Scale, and the General Sleep Questionnaire. The severity of stroke was assessed by the National Institutes of Health Stroke Scale and the Rankin Disability Scale. Patients with a Glasgow score <8 on the day of neuropsychiatric examination were excluded from the study, as well as patients with epileptic seizures at the onset of stroke, with aphasia, with Mini - mental test <23, with verified previous dementia / cognitive impairment. RESULTS: There is no statistically significant difference in the age of men and women, both with apnea and without apnea. In patients with apnea, heart disease was in the first place 91.8%, followed by hypertension 86.4%, Body mass index 79.1%, hyperlipidemia 50%, smoking 38.2 % and diabetes mellitus 20.9%. Hypertension was the most common risk factor in patients without apnea 83.6%, followed by heart disease 81.0%, Body mass index 60.9%, hyperlipidemia 48.21%, smoking 28.2 % and diabetes mellitus 20%. CONCLUSION: Heart diseases, hypertension and body mass index are significantly more frequent in patients with than in patients without sleep apnea.

Cognitive syndromes after the first stroke.

AIM: The aim of this study is to determine impairments of certain cognitive functions in certain vascular cognitive syndromes and to identify predictors of dementia. PATIENTS AND METHODS: One-year prospective study included 275 patients, who were hospitalized at the Department of Neurology Tuzla and therefore fulfilled certain criteria. Patients were divided into following subgroups of vascular cognitive impairment (VCI): dementia of strategic infarct (DSI), cortical dementia (CD), sub cortical dementia (SCD), hemorrhagic dementia (HD), and patients without dementia. Each of the patients underwent the clinical examination and scoring with appropriate measurement scales. RESULTS: Some of the types of VCI were verified in 190 (69%) patients, and the most common was SCD (58%). There was statistically significant connection between the level of intelligence and occurrence of VCI in patients after stroke (p < 0.001). We found significant connection between occurrence of dementia and impairment in narrative memory, numerical memory, visual perceptive, and visual constructive functions in patients with dementia compared with non-demented (p = 0.0001). The executive functions were statistically impaired in patients with CD (p = 0.004) and SCD (p < 0.001). Patients without dementia have significantly better quality of life than the demented ones (p < 0.0001). The algorithm "tree of decision" can help us in the prediction of dementia based on the impairment of certain cognitive functions. CONCLUSION: Vascular cognitive syndromes are common after stroke. Some of the cognitive functions are significantly impaired in patients with dementia. Impairment of the certain cognitive functions can help in predicting the onset of dementia. Patients without dementia have better quality of life.

Characteristics of stroke in young adults in Tuzla Canton, Bosnia and Herzegovina.

The aim of the study was to analyze stroke in young adults in Tuzla Canton, Bosnia and Herzegovina. From January 2001 to December 2005, 3864 patients with first-ever stroke were admitted at the Department of Neurology Tuzla. A retrospective analysis of risk factors, stroke types, severity and one month outcome in all young adults (18-45 years of age) with first-ever stroke was carried out. Out of total, there were 154 (4%) young adults with stroke. Mean age was 38.8 +/- 5.7 years and 47% were women. The leading risk factors were smoking (56%) and hypertension (45%). Subarachnoid hemorrhage (SAH) was more frequent in young adults compared with older patients (> 45 years of age) (22% vs. 3.5%, p < 0.0001), intracerebral hemorrhage (ICH) was similar in both groups (16.9% vs. 15.8%, p = 0.7), but ischemic stroke (IS) was predominant stroke type in the older group (61% vs. 74%, p = 0.0004). Young adults had more frequent lacunar stroke (26.6% vs. 16.1%, p = 0.01) and stroke due to other etiology (8.5% vs. 1.8%, p = 0.0004) than stroke patients over 45 years of age. Stroke severity at admission was lower in young adults than in older patients (p < 0.0001), as well as mortality at one month (11% vs. 30%, p < 0.0001). Favorable outcome (modified Rankin Scale < or = 2) had 71% of young adults compared with only 53% of patients in the older group (p = 0.0003). Stroke in young adults in Tuzla Canton is rare. Risk factors profile, stroke types, severity and outcome at one month in young adults are different from those in older patients.

Does the volume and localization of intracerebral hematoma affect short-term prognosis of patients with intracerebral hemorrhage?

The aim of this study was to determine whether volume and localization of intracerebral hematoma affects the six-month prognosis of patients with intracerebral hemorrhage (ICH). Patients and Methods. The study included 75 patients with ICH of both sex and all age groups. ICH, based on CT scan findings, was divided in the following groups: lobar, subcortical, infratentorial, intraventricular haemorrhage and multiple hematomas. Volume of intracerebral hematoma was calculated according to formula V = 0.5 × a × b × c. Intracerebral hematomas, according to the volume, are divided in three groups (0-29 mL, 30-60 mL, and >60 mL). Results. The highest mortality rate was recorded in the group with multiple hematomas (41%), while the lowest in infratentorial (12.8%). The best six-month survival was in patients with a volume up to 29 mL, 30 of them (64%) survived. The highest mortality rate was recorded in patients with the hematoma volume >60 mL (85%). Kaplan-Meier's analysis showed that there was statistical significance between the size of the hematoma and the six-month survival (P < 0.0001). More than half of patients (61.1%) who survived 6 months after ICH were functionally independent (Rankin scale ≤2). Conclusion The volume of hematoma significantly affects six-month prognosis in patients with intracerebral hemorrhage, while localization does not.

Aphasia disorders outcome after stroke.

INTRODUCTION: Aphasia is considered to be the most difficult disorders of speech-language communication, and is often companion by all forms of cerebrovascular disease. GOAL: To determine the outcome of aphasia disorder a year after a stroke and stroke type influence on the outcome of aphasia disorders. MATERIAL AND METHODS: We analyzed one-year outcome of aphasia disorders in patients who had a first stroke. Patients were tested by a speech pathologist with the International test for aphasia, immediately after admission and one year after the stroke. All patients that were hospitalized during treatment had a speech therapy and only a small number of patients were realsed from hospital. RESULTS: Out of 74 patients with aphasia who were discharged from hospital within one year 20 patients died and 2 patients did not respond to control clinical treatment review. Analysis of the remaining 52 respondents determined that out of the 10 patients with global aphasia 8 (80%) evolved into another aphasia syndrome, and two (20%) remained unchanged in form. In most cases, global aphasia was transformed in mixed non fluent aphasia (4 of 10 patients or 40%), and in two cases (20%) global aphasia was transformed in Broca aphasia. Broca aphasia (n = 20) in other forms evolved in 9 patients (45%), and 11 patients (55%) remained unchanged in form. Anomic aphasia had 11 patients (78.6%) which remained unchanged in form, while 3 (21.4%) evolved into an Alexia agraphia. Full recovery was noted in two patients (3.84%). Type of stroke did not affect the outcome of aphasia disorders. Out of the 52 analyzed patients after hospitalization, unfortunately, only 11 (21.2%) had some kind of speech pathology treatment after leaving the hospital. CONCLUSION: One year after the stroke severe aphasia evolved into a lighter form in a significant number of patients. Most often anomic aphasia remained (34.6%), followed by Broca (25%) and Conductive aphasia (7.7%). Type of stroke does not affect the outcome of aphasia disorders. Unfortunately only a small number of patients (21.2%) continued with aphasia speech therapy after leaving the hospital.

Sex differences in patients with acute ischemic stroke in Tuzla region, Bosnia and Herzegovina.

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

Reduction of stroke mortality in the Tuzla region, Bosnia and Herzegovina.

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%.

Analysis of risk factors, localization and 30-day prognosis of intracerebral hemorrhage.

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.

[Obstetric lesions of brachial plexus]. / Porodajne lezije pleksusa brahijalisa.

BACKGROUND: Obstetrical brachial plexus lesion (OBPL) (also known in its various forms as Erb's palsy, Klumpke's paralysis, Erb-Duchenne palsy) complicates a very small proportion of births. Furthermore, it seems that more likely many cases recover with little in the way of remaining deficit, but it is equally certain that some cases will not recover. Electro diagnostic examinations are used as following the physical examination and can provide data on both the severity and timing of the injury. The initial study usually is performed 2-3 weeks after injury, when signs of enervation are seen in children with moderate or serious injuries. The incidence of obstetric brachial plexus palsy varies from 0.4 to 1 case per 1000 new born children. This incidence has remained unchanged since the beginning of this century despite current technologic advances. The aim of this paper is to review the literature and authors experience with OBPL. PATIENTS AND METHODS: The study included 30 children examined in last 10 years at Electro myoneurography laboratory, Department of Neurology, University Clinical Center Tuzla, Bosnia and Herzegovina. RESULTS AND DISCUSSION: Total out of 20 children (66.67%) were male, and 10 (33.3%) female; in 11 (36.67%) palsy was on left, and in 19 (63.33%) on right side. Erb's palsy was seen in 27 (90%) and total palsy in the remaining 3 (10%) limbs. Electromyography was very useful test not only for diagnosis, but also for evaluation of recovery. Good recovery was observed in majority of these children, but some children has difficulty with active shoulder abduction, forward flexion, symmetric elbow flexion and forearm supination at age of one year and more, and mild shortening and atrophy of the limb are also observed.

Stroke in patients with diabetes mellitus: a hospital based study.

INTRODUCTION: Diabetes mellitus is a risk factor for stroke, but it is unclear whether stroke is different in diabetic and nondiabetic individuals. The aim of the study was to compare characteristics of stroke in patients with and without diabetes mellitus. METHODS: This study included 833 acute stroke patients (697 [84%] had ischemic stroke, and 52% were females) admitted at the Department of Neurology Tuzla, Bosnia and Herzegovina, from January 1st 2003 to December 31st 2003. Risk factors, stroke severity (Scandinavian Stroke Scale, SSS)), stroke type, etiology, lesion topography and the outcome at 1 month (mortality and handicap) were assessed in all patients. RESULTS: Overall, diabetes mellitus was present in 194 patients (23.5%). Females were overrepresented in the diabetic group of stroke patients (66% vs 48%, p = 0.0001). Initial stroke severity and lesion topography were comparable between the two groups. The diabetic patients reported a significantly lower current smoking (21% vs 29%) and alcohol intake (4.5% vs 9%) (p < 0.05). Patients with diabetes mellitus compared with patients without diabetes had more frequently atherothrombotic stroke (62% vs 33%, p < 0.0001), but less frequently embolic stroke (10% vs 17.5%, p = 0.02) and intracerebral hemorrhage (10% vs 18.5%, p = 0.005). Mortality at 1 month was higher in patients with diabetes mellitus (38% vs 26%, p = 0.001), and diabetes increased the relative death risk by 1.53 (95% confidence interval, 1.19 to 1.96). At the other hand, handicap (Rankin Scale) in surviving patients was insignificantly higher in diabetic group (2.7 vs 2.4, p = 0.07). Older age (70 vs 66 years, p = 0.008), atherothrombotic stroke (76% vs 53%, p = 0.002), and severe strokes (SSS 20.5 vs 39, p < 0.0001) were more associated in died stroke patients with diabetes mellitus compared with surviving diabetic stroke patients. CONCLUSION: Diabetes mellitus is present in one fourth of acute stroke patients. Stroke patients with diabetes mellitus are associated with specific patterns of stroke type, etiology and mortality but not with stroke severity and handicap.
