Prevalence and correlates of post-traumatic stress disorder after ischaemic stroke.

Although most often considered a consequence of traumatic event, post-traumatic stress disorder (PTSD) also occurs after illness. The aim of this study was to establish prevalence of PTSD in patients with ischaemic stroke (IS) and its correlation to lesion location, degree of disability, age, gender and marital status. The study included 85 patients with IS. PTSD was diagnosed using a modified version of the PTSD Checklist Specific for a stressor (PCL-S). Depression and anxiety were assessed using Hospital Anxiety and Depression Scale (HADS). We defined stroke localisation as right cerebral hemisphere, left cerebral hemisphere, brainstem and cerebellum. Stroke severity was measured using the modified Rankin scale (mRS). Demographic information including age, gender and marital status was collected from medical history. Of the 85 patients with IS, 11 (12.9%) fulfilled PCL-S criteria for PTSD. We found a positive correlation between PTSD and higher degree of disability, P < 0.001. Patients with PTSD had lesions more frequently localised in the right cerebral hemisphere and the brainstem. We found no statistically significant correlation of PTSD with age, gender and marital status. Our results show that a significant number of IS patients develop PTSD after IS. Determining correlates of post-stroke PTSD can help to identify those at higher risk for its development. If proven by additional large sample studies, more patients can benefit from screening for the PTSD symptoms.

HEADACHES IN ADOLESCENTS - FREQUENCY, RISK FACTORS AND OTHER HEALTH COMPLAINTS: A CROSS-SECTIONAL STUDY IN CROATIA.

- Headaches are very common in school population. The aim of this study was to determine epidemiological data on headaches among Croatian schoolchildren and their connection to risk factors and other health complaints. In the study, we used the Croatian database of the international research entitled Health Behavior in School-aged Children for 2013/2014. It is a cross-sectional study conducted every four years in 44 countries among children aged 11-16. The students were interviewed using an anonymous standardized questionnaire. The Croatian sample consisted of 5741 students, of which 2857(49.8%) girls and 2884 (50.2%) boys. The response rate was 85.9%. Headaches were reported to be often (once a week to daily) by 23.5% of students and were more often in girls and in higher school grades. They were positively linked to cigarette smoking and health complaints such as back pain and stomachache, bad mood, nervousness, irritability, difficulties with sleeping and dizziness. Headaches are associated to many health problems and can cause difficulties in student functioning. This could be a serious problem. This study pointed to connection of headaches with cigarette smoking and importance to underpin the smoking prevention programs.

Incidence of Stroke and Transient Ischemic Attack in Croatia: A Population Based Study.

The aim of this population based neuroepidemiological study was to establish the real incidence rates of acute cerebrovascular disease (CVD): stroke and transient ischemic attack (TIA) in the Republic of Croatia. Multicentric study included 89 501 persons of all ages in four regional centres in Croatia: Zagreb, Osijek + Slavonski Brod, Rijeka and Split. The following incidence rates of stroke, expressed at population of 100 000, have been established: Zagreb 290.52, Osijek + Slavonski Brod 302.14, Rijeka 219.65, Split 195.82. Incidence rate of stroke for the Republic of Croatia is 251.39. The following incidence rates of TIA, expressed at population of 100,000, have been established: Zagreb 87.15, Osijek + Slavonski Brod 156.53, Rijeka 90.11, Split 59.10. Incidence rate of TIA for the Republic of Croatia is 100.55. In the continental part of Croatia (Zagreb, Osijek + Slavonski Brod) incidence rate of stroke is higher by 45%, while incidence rate of TIA is higher by 82% than in the coastal part of Croatia, probably due to different lifestyle and environmental factors. The study has shown relatively high incidence rates of acute CVD (stroke and TIA) in the Republic of Croatia, which proves that CVD are a great public health problem.

Postoperative quality of life after two different methods of tonsillectomy.

BACKGROUND AND OBJECTIVES: Tonsillectomy is a very painful procedure. Pain may be severe, and patients are often unable to perform in school or eat regular food for a number of days after the surgery. The aim of this study was to compare the quality of life after undergoing two different surgical techniques of tonsillectomy, harmonic scalpel and classic tonsillectomy with bipolar cauterization. DESIGN AND SETTING: Prospective randomized double-blind, clinical trial study conducted in the ENT Department, Dr. Josip Bencevic General Hospital, Slavonski Brod, Croatia. PATIENTS AND METHODS: Data were collected, according to the type of operation, on pain persistence and intensity and returning to normal eating with tonsillectomy patients during the first seven postoperative days. Group A consisted of 50 children submitted to classic tonsillectomy with bipolar cauterization, while group B included 50 children operated on using the harmonic scalpel. Data on pain intensity were obtained using pain measuring scales adjusted to children's age (Faces scales, visual analog scale). The first day of normal oral food intake was recorded. RESULTS: The analysis of variance revealed that the grade of pain significantly differs by a surgical technique employed, and that it significantly varied over the first seven postoperative days. The pain was more severe after undergoing the harmonic scalpel technique and children started to eat later compared with the classic tonsillectomy. CONCLUSION: The classic tonsillectomy method with bipolar cauterization is the method of choice due to lower postoperative pain levels and sooner normal eating. The quality of life is better after undergoing the classic tonsillectomy method.

Aphasia in patients with ischemic stroke.

Aphasia in ischemic stroke patients is associated with increased mortality, decreased rates of functional recovery, and reduced work capability. The aim was to study the prevalence and characteristics of aphasia in ischemic stroke patients. This prospective, cohort study included 177 patients (94 male and 83 female) hospitalized for ischemic stroke at University Department of Neurology in Osijek in 2010. All patients were examined by a neurologist and speech therapist to specify the subtype of stroke and speech disturbance. The study showed 75 (42.4%) study patients to have aphasia (48.2% of females and 37.2% of males). The most frequent clinical type was expressive-receptive aphasia. Aphasic patients were statistically significantly older (75 vs. 70 years) and showed female predominance (53% vs. 42%). Patients with aphasia also had a threefold share of large vessel stroke (51% vs. 17%) and approximately twofold share of cardioembolic stroke (41% vs. 22%). The share of left hemisphere stroke was nearly twofold in aphasic (61%) compared to non-aphasic (31%) patients. The study showed a high prevalence of aphasia in patients with ischemic stroke, which increased with age, was more pronounced in females and most frequently found in patients suffering from large vessel stroke and cardioembolic stroke.

The prevalence of neurocranium injury in children in Brod-Posavina County.

Head injuries are very common in children and are the most frequent cause of disability and death among children. This retrospective study included 350 children hospitalized for injury of neurocranium over a 5-year period at Dr Josip Bencevic General Hospital in Slavonski Brod. Boys were more commonly injured (63.4%) than girls. The most common injuries were recorded in children aged 7-14 (47.1%), followed by those aged 1-6 (33.8%) years. The injuries occurred slightly more often in urban (50.9%) than in rural (46.6%) setting. Children were more commonly injured in the street or on the road (38.6%), followed by injuries sustained at home (35.2%), at school (9.3%) and on playgrounds (5.7%). They were most commonly injured by fall (50%), followed by traffic injuries (33.5%). Statistically significant differences were found in the following age groups: all children younger than one year were injured by fall; children aged 1-14 were mostly injured by fall (less in traffic, and due to hitting), and those aged 15-18 mostly in traffic (less by fall and due to hitting). Children were mostly injured in the street or on the road (in traffic accidents), followed by injuries at home (mostly by fall), at school and around the house or in the yard (mostly by fall); on the playground (due to hitting) and on the road (in traffic accidents) (statistically significant difference). Most of them had head contusion and cerebral commotion combined (46.8%), followed by head contusion alone (12.5%) and skull fractures (10.5%). Hemorrhages and hematomas were rare (epidural, subdural, subarachnoid hemorrhage), found in 3.2% of cases. We hope that our results will prove helpful in planning preventive measures and treatment of injured children.

Effect of elevated catecholamine levels on cerebral hemodynamics in patients with chronic post-traumatic stress disorder.

The aim of the study was to assess the correlation between the levels of catecholamines and cerebral hemodynamics in patients with chronic post-traumatic stress disorder (PTSD). The study included 50 patients with chronic PTSD hospitalized for psychiatric treatment for the first time, and 50 healthy control subjects. All study subjects were in the 30-50 age group. In PTSD group, determination of vanllylmandelic acid (VMA), an epinephrine and norepinephrine metabolite, in 24-h urine and transcranial Doppler (TCD) sonography of the circle of Willis vasculature were performed on the first day of hospital stay. The same diagnostic procedures were repeated upon the completion of 21-day medicamentous psychiatric treatment. Initial analysis revealed concurrently elevated 24-h VMA in 29 (58.00%) patients and increased values of the mean blood flow velocity (MBFV) in the circle of Willis vasculature in 34 (68.00%) patients, indicating a high correlation of the respective parameters (p = 0.3290). Second analysis performed after 21-day psychiatric treatment showed concurrently elevated 24-h VMA in eight (16.00%) patients and increased MBFV in the circle of Willis vasculature in nine (18.00%) patients, also pointing to a high correlation of the parameters observed (p = 0.7906). In the control group, only two (4.00%) subjects had elevated MBFV in the circle of Willis vessels, whereas the level of 24-h VMA was normal in all control subjects. Study results pointed to a significant association between elevated levels of stress hormones and increased MBFV in the circle of Willis vasculature caused by cerebral vasospasm. Medicamentous psychiatric treatment for PTSD administered for three weeks significantly reduced the proportion of PTSD patients with elevated levels of the catecholamine metabolite and cerebral vasospasm. Study results showed a high correlation between diurnal VMA level and elevated MBFV in the circle of Willis vessels, clearly demonstrating the effect of prolonged elevation of catecholamine levels on cerebral hemodynamics.

Motor and cognitive impairment after stroke.

Cognitive abilities have great impact on rehabilitation program in stroke patients. Therefore, fast and practical psychometric assessment as an indicator of individual rehabilitation program is of great importance. The aim of this study was to analyze and compare motor and cognitive impairment in stroke patients in acute, subacute and chronic phase of the disease, taking age, sex, education, stroke risk factors, lateralization and type of stroke in consideration. The study included 50 stroke patients, 33 male and 17 female. Ischemic stroke was diagnosed in 78% and hemorrhagic stroke in 22% of patients. Hypertension was the leading stroke risk factor in 82% of patients. Cognitive impairment in acute, subacute and chronic phase of the disease was noticed in 12% of stroke patients with ischemia in the left brain hemisphere, mMMSE average score 31 and SKT score 19, IQ under 90. Better motor recovery in acute and subacute phase of stroke was followed by better cognitive status. All cognitively impaired stroke patients had low level of education, some had accomplished elementary education and others had not, all much below the dementia risk age of 75 years. Exclusion of patients with severe stroke from the study led to overestimation of the results. Finally, a coherent algorithm for somatic and cognitive stroke assessment in stroke patients poses itself as an imperative as a guideline for plastic, individualized and appropriate rehabilitation.

Are we ready for intravenous thrombolysis in acute stroke treatment in our region?

Acute stroke is the leading cause of disability in modern society. Early treatment is crucial to maximize the benefit of stroke intervention. Effective thrombolytic therapy is dependent on timely intervention and guidelines for the recommended use of recombinant tissue plasminogen activator therapy within 3 hours after onset of stroke symptoms. The aim of the study was to assess whether we are ready for the introduction of thrombolysis in our region. We investigated retrospectively the time from symptom onset to hospital arrival (delay time) for patients with acute stroke in our region. Medical histories of all patients admitted to the Department in 2006 with acute stroke symptoms were studied. Statistical analysis was performed by use of the SigmaStat (version 2.0) software. Study results showed that a very high rate of patients presented after 24 hours of stroke onset (35%); 15% of all acute ischemic stroke (AIS) patients arrived within 3 hours of stroke onset. Due to other exclusion criteria established, only 4% of all AIS patients were eligible for intravenous thrombolysis. Most patients arrived in the hospital too late to get maximum benefit from the emerging stroke therapies. This may be due to the failure to recognize signs and symptoms or the lack of awareness of the potential treatment benefits. Our further efforts should be focused on increasing public awareness of the stroke signs and symptoms and on reducing delay time.

The effect of stress hormones on cerebral hemodynamics in patients with chronic posttraumatic stress disorder.

The aim of the study was to assess the possible correlation between catecholamine and cortisol levels and changes in cerebral hemodynamics in patients with chronic posttraumatic stress disorder (PTSD). The study included 50 patients with chronic PTSD first ever hospitalized for psychiatric treatment and 50 healthy control subjects. All study subjects were aged 30-50. In PTSD patients, 24-h urine levels of the epinephrine and norepinephrine metabolites vanillylmandelic acid (VMA) and cortisol were determined and transcranial Doppler ultrasonography was performed on day 1 of hospital stay and repeated after 21-day psychiatric medicamentous treatment. On initial testing, increased level of 24-h VMA, decreased cortisol level and elevated mean blood flow velocity (MBFV) in the circle of Willis vessels were recorded in 25 (50.00%) patients. Repeat findings obtained after 21-day psychopharmaceutical therapy showed increased 24-h VMA, decreased cortisol and elevated MBFV in the circle of Willis vessels in seven (14.00%) patients (initial vs. repeat testing, P = 0.0002). Such parameters were not recorded in any of the control subjects (initial PTSD patient testing vs. control group, P = 0.0000). Study results pointed to a significant correlation between increased catecholamine levels, decreased cortisol level and elevated MBFV in the circle of Willis vessels caused by cerebral vasospasm. Psychiatric medicamentous therapy administered for three weeks significantly reduced the proportion of patients with concurrently altered cerebral hemodynamics, increased levels of catecholamine metabolites and decreased level of cortisol.

[Painful ophthalmoplegia--Tolosa-Hunt syndrome]. / Bolna oftalmoplegija--Tolosa-Huntov sindrom.

Tolosa Hunt syndrome is a rare disorder caused by nonspecific inflammation in the cavernous sinus/superior orbital fissure and/or orbital apex. It is clinically characterized by alternating remissions and exacerbations, and manifested as diplopia associated with unilateral periorbital hemicranial headache. The symptoms include blepharoptosis, which is usually mild if present, bulbomotor paresis involving the pupil, and loss of sensation in the area supplied by the first division of the trigeminal nerve. Therapy for Tolosa-Hunt syndrome are systemic steroids. The course of disease in a 25-year-old man hospitalized for painful ophthalmoplegia and diplopia is presented. The history included severe pain on rightward eye movement and parabulbarly on the right, considerable defect in the area supplied by the first division of the trigeminal nerve, right hemicrania, and diplopia on looking to the left, right, upward and downward that developed after four days. A month before, the patient was observed at neurology department for severe right hemicrania. Current status included severe pain parabulbarly on the right, discrete proptosis with mild ptosis on the right eye, restricted right eye bulbar motoricity on looking nasally, nasally upward and downward, and loss of sensation in the area supplied by the first division of the trigeminal nerve. Pupilar motoricity was normal. Upon admission, neuroradiologic examination (orbit CT) and brain MR were performed, and therapy with systemic corticosteroids was initiated ex iuvantibus, in consultation with a neurologist. At 24 hours of corticosteroid therapy, the pain subsided, whereas diplopia disappeared almost completely after 5 days, now being only occasionally recorded on looking to the left and upward.

[Prevalence of acute cerebrovascular disease in Bizovac, Osijek-Baranya county: a door-to-door survey in eastern Croatia]. / Prevalencija akutne cerebrovaskularne bolesti na podrucju opcine Bizovac u Osjecko-Baranjskoj zupaniji: rezultati populacijske studije vrata-do-vrata.

BACKGROUND AND PURPOSE: A door-to-door survey was carried out in Bizovac area, Osijek-Baranya County in east Croatia. A cluster sample of 1899 inhabitants were screened to determine the prevalence of acute cerebrovascular disease (CVD): transient ischemic attacks (TIA) and stroke in this population. METHODS: We used a modified version of the World Health Organization screening instrument. A door-to-door survey of stroke was conducted in five Osijek suburbs, east Croatia. The data obtained were compared with data in personal records of the study subjects. RESULTS: On March 31, 2005, the prevalence of acute CVD was 3370/100.000 (stroke 1948/100,000 and TIA 1422/100,000), of CVD in males 3047/100,000 (stroke 1959/100,000 and TIA 1088/100,000); of CVD in females 3673/100,000 (stroke 1939/100,000 and TIA 1735/100,000); and the prevalence of acute CVD progressively increased with age: in 45-54 age group 1290/00,000 (stroke 942/100,000, TIA 348/100,000); in 55-64 age group 7895/100,000 (stroke 5623/100,000, TIA 2272/100,000); in 65-74 age group 11386/100,000 (stroke 7393/100,000, TIA 3993/100,000); and in 75-84 age group 14035/100,000 (stroke 10001/100,000, TIA 4034/100,000) as the highest figure. CONCLUSION: The study revealed a very high prevalence of acute CVD in the study area and confirmed CVD as one of the leading medical and public health issues in Bizovac area, Osijek-Baranya County, east Croatia.

Mortality of cerebrovascular diseases in Croatia--1958-1997.

The aim of this investigation was to analyze secular trend of mortality from cerebrovascular diseases in Croatia and its regional characteristics. The research comprised all deaths from cerebrovascular diseases in Croatia in persons aged between 35 and 74 years over the period 1958-1997. The investigated period is divided in eight 5-year periods, and for that 5-year periods proportional mortality rates, standardized mortality rates and specific mortality rates, according to the age and gender were calculated. Number of all deaths in the population aged 35-74 in Croatia, by 5-year periods rose from 18,913 to 26,788 (increase of 42%), deaths from cerebrovascular diseases from 2831 to 3959 (increase of 40%). Proportional mortality rate for this disease increased from 9.0% in the first 5-year period to 14.8% in the last 5-year period (increase of 64%). Standardized mortality rates for cerebrovascular diseases increased from 118 to 206 per 100,000 inhabitants (increase of 75%). The specific mortality rates over a 5-year period have shown a trend of increase in all men age groups and stagnation or decrease in women age groups. At the same time the rates standardized by age and sex increased by 62%. Standardized mortality rates for cerebrovascular diseases in continental communities (Osijek, Varazdin) are much higher (twice or even threefold) than those in coastal communities (Split, Rijeka). A data analysis showed that, although mortality trends of cerebrovascular diseases stagnated or even declined in some communities during the recent years, the secular trend for the entire country had a tendency of constant rise over the whole period of research. Therefore, the short-term prognosis predicts further increase of both the number and rates of deaths from cerebrovascular diseases in our country.

Transcranial Doppler ultrasound assessment of intracranial hemodynamics in patients with type 2 diabetes mellitus.

BACKGROUND: Diabetics have a 3-fold risk for cardiovascular diseases compared with non-diabetics. This study was designed to evaluate cerebral hemodynamic changes related to type 2 diabetes mellitus (DM) with transcranial Doppler ultrasonography (TCD). TCD is a highly sensitive and specific method of quick bedside assessment of cerebrovascular circulation hemodynamics. PATIENTS AND METHODS: In a prospective study, we compared a group of 100 patients with the diagnosis of type 2 diabetes mellitus (aged 48 to 67 years) and an age- and sex-matched control group of 100 healthy subjects without diabetes mellitus. We measured flow velocities (Vm) and the Gosling pulsatility index (PI) of the middle cerebral artery (MCA). RESULTS: The rate of TCD abnormalities was significantly higher in diabetic patients than in healthy control subjects (55% vs. 11%, P < 0.05). The PI was significantly higher in diabetic patients than in healthy controls (P < 0.001). Atherosclerotic changes were found in 34.0% and 71.4% of patients suffering from diabetes for <5 and > or =5 years, respectively. CONCLUSION: This study suggests that TCD is a useful marker for the detection of diabetic cerebrovascular changes. The duration and type of diabetes were found to have an impact on the development of pathologic cerebrovascular changes.

Stroke is the leading cause of disability in modern society. In developed countries stroke is the second or the third cause of death, and in Croatia it is the leading cause of death. Therefore, stroke is not only a great medical, but also economic burden. Figures show that the incidence of stroke in transitional countries is increasing, so the epidemic of stroke could be expected in the forthcoming years. The Croatian Society for Neurovascular Disorders of the Croatian Medical Association and the Croatian Stroke Society wrote the recommendations for stroke management. The first part presents the recommendations for organization of stroke care, stroke treatment and neurorehabilitation, and the second part will present the recommendations for prevention of stroke.
