Background: Epilepsy is a brain disorder characterised by unpredictable and excessive nerve cell activity that causes epileptic seizures. Epileptic seizures are more common in children and adolescents than in elderly population. Electroencephalography (EEG) is a diagram of electrical activity of the brain and it is used as a method of choice for diagnosing epilepsy. Despite the accurate EEG tracing of electrical activity in the brain, the disadvantage of this type of analysing is the doctor’s skill to read the EEG correctly. Objective: The aim of this study was ro represents further research presented in our pevious works with wavelet based EEG analysis after masuring a multiresolution as relation between time and frequency resolution. Methods: Signal database set consist of 51 patients: a) healthy patient; b) 50 patients with a diagnosis of epilepsy. Additional characteristics of the analysed data: a) 19 signals-channels of EEG, b) Duration – 20 s or 2688 samples and. Nowadays, we can find dozens of EEG signal analysis papers using mathematical approach and with a focus on identification of epilepsy. Results: This paper represents some results relating to the analysis of EEG in children using Wavelet Transform (WT). The signals was collected and analysed at the Department of neuropediatrics, Pediatric Clinic at the University Clinical Center, University of Sarajevo. Conclusion: Using this approach it is possible to clearly differentiate patients with a diagnosis of epilepsy from healthy ones.
Introduction: Epilepsy is one of the most common neurological diseases in childhood and adolescence. Carbamazepine (CBZ) and valproate (VPA) have been widely used as the first generation of antiepileptic drugs (AED). Aim: The aim of the study has been to evaluate and compare the effect of CBZ and VPA monotherapy on aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma-glutamyltransferase (GGT) serum levels in children. Material and methods: The study has included 100 patients (boys 57/girls 43, age range 1 to 18 years), who have been treated with CBZ or VPA, as initial monotherapy, for at least 12 months. Patients with liver lesions or patients who have been treated with other drugs have been excluded from the study. The initial serum enzyme levels (AST, ALT and GGT) and after 12 months of treatment have been compared. Results: 53/100 (53%) patients have been treated with CBZ and 47/100 (47%) patients have been treated with VPA.The initial level of enzymes were within the referece range. After one year-long treatment AST was elevated at 4/53 (7.5%) CBZ patients and 9/47 (19.15%) VPA patients (x2 test =3.965, p<0.05). ALT was elevated at 5/53 (9.4%) CBZ patients and 9/47 (19.15%) VPA patients (x2 test =6.953, p<0.05). GGT was elevated at 18/53 (34%) CBZ patients and 7/47 (14.9%) VPA patients (x2 test =4.831, p<0.05). Conclusion: The levels of enzymes AST and ALT have been elevated statistically significant in VPA group and GGT in CBZ group.
Introduction: Patients with cerebral palsy (CP), besides the basic neurological damage, are also often undernourished. Adequate nutrition for children is very important during the period of intensive growth and development, which is of particular importance in patients with CP. Goal: To evaluate the nutritional status of patients with CP who are treated at the Pediatric Clinic, Clinical Centre of Sarajevo University and causes of malnutrition in these patients. Materials and Methods: Eighty patients with CP underwent anthropometric assessment (body weight, body height, body mass index, head circumference, subscapular skinfold thickness, triceps skinfold thickness and mid upper arm muscle circumference). Severity of CP was classified based on the Gross Motor Function Classification System (GMFCS). We compared the anthropometric parameters of our patients with normal values of healthy children, as well as with degree of motor impairment, oromotor dysfunction, feeding assistance, length of meals and daily feeding time. Results: There were significant differences in all monitored parameters in relation to normal values, with 38 (47.5%) malnourished patients in the total group, out of which 29 (63.0%) with severe motor impairment and with 9 (11.3%) obese patients in the total group. The presence of oromotor dysfunction and other monitored parameters had a significant impact on the nutritional status of these patients. Conclusion: In severely disabled patients with CP there is a risk of profound malnutrition. Early identification and treatment of these patients is very important for their growth, development and health.
Introduction: Unilateral spastic cerebral palsy (US CP) is the second most common subtype of cerebral palsy. Aim: The aim of the study was to analyze neuroimaging findings in children with unilateral spastic cerebral palsy. Material and methods: The study was hospital based, which has included 106 patients with US CP (boys 72/girls 34, term 82/preterm 24). Neuroimaging findings were classified into 5 groups: Brain maldevelopment, predominant white matter injury, predominant gray matter injury, non specific findings and normal neuroimaging findings. Results: Predominant white matter lesions where the most frequent (48/106,45.28%; term 35/preterm 13), without statistically significant difference between term and preterm born children (x2=0.4357; p=0.490517). Predominant gray matter lesions had 32/106 children, 30.19%; (term 25/preterm 7, without statistically significant difference between term and preterm born children (x2=0.902; p=0.9862). Brain malformations had 10/106 children, 9.43%, and all of them were term born. Other finding had 2/106 children, 1.89%, both of them were term born. Normal neuroimaging findings were present in14/106 patients (13.21%). Conclusion: Neuroimaging may help to understand morphological background of motor impairment in children with US CP. Periventricular white matter lesions were the most frequent, then gray matter lesions.
AIM To determine the amount of stress to which young and adult persons were exposed during the last twelve months and relationship between stress levels and risky health behavior. METHODS The study was conducted from November 2011 until January 2012 in the Sarajevo Canton. The study included 700 respondents divided into two groups: 350 young people aged 15- 27 years and 350 adults aged over 27 years. As an instrument for data collection a questionnaire was used to provide information on demographic characteristics of respondents and habits, as well as Holmes and Rahe stress scale to determine the level of stress. RESULTS The average value of the stress scale score was 302.56±149.75 for the total sample, 331.7±165.7 for youth and 273.5±125.6 for adults. Respondents from the group of young people in the last twelve months had an average of 3.6 highly stressful events and 1.9 in the group of adults. In the group of young people there were more respondents with inadequate nutrition (p=0.023) and more smokers (p=0.128). In the group of adults more people were overweight (p=0.001) and had reduced physical activity (p=0.006). Both study groups had an equal number of respondents who consumed alcohol. People with high levels of stress consumed alcohol significantly more (p=0.03) and smoked (p=0.02) compared to those with low levels of stress. CONCLUSION The respondents of both groups were exposed to large amount of stress that was associated with smoking and alcohol consumption. There is a need to design appropriate strategies for coping with stress and their implementation in lifestyle.
Central nervous system (CNS) malformations represent important factor of morbidity and mortality in children. The aim of the study was to determine the incidence, type and clinical features of CNS malformations in children who were admitted at the Neonatal and Child Neurology Department, Neonatal Intensive Care Unit and Paediatric Intensive Care Unit of Paediatric Clinic, University of Sarajevo Clinics Centre, from January 1st, 2002 to December 31st, 2006. There were total of 16520 admissions at the Paediatric Clinic over the studied period. CNS malformations, solitary or multiple, have been diagnosed in 100 patients (0,61%). The total number of various CNS malformations was 127. Lethal outcome was established in 9/100 cases (9%). The most frequent CNS malformations were neural tube defects 49/127 (38,6%). Hydrocephalus was seen in 34/127 (26,8%), microcephaly in 24/127 (18,9%), agenesis of corpus callosum in 10/127 (7,9%), Dandy Walker malformation in 6/127 (4,7%) and other CNS malformations in 4/127 (3,1%). In 20/100 of patients neural tube defect was associated with hydrocephalus (20%). CNS malformations were prenatally diagnosed in 13/100 of patients (13%). Primary prevention of CNS malformations can be improved in our country by better implementation of preconceptional folic acid therapy for all women of childbearing age. Secondary prevention by prenatal diagnosis requires advanced technical equipment and adequate education of physicians in the field of foetal ultrasonography. In our circumstances, prenatal diagnostics of CNS malformations is still not developed enough.
Intraventricular-periventricular hemorrhage (IVH-PVH) is the most frequent type of intracranial hemorrhage in premature infants and the major cause of neurodevelopmental disabilities in children too. The objective of this work is to evaluate the effects of prenatal corticosteroid treatment on the incidence of IVH-PVH in premature infants. The study enrolled 163 prematures of 26-34 weeks’ gestation. They have been divided into two groups: the experimental group (80/163), who have been treated with corticosteroids prenatally and control group (83/163), who have not received such treatment. There is statistically significant difference in IVH-PVH incidence between the experimental group (18/80) and control group (32/83) (χ 2 =5,616, p<0,05). There is no statistically significant difference in Apgar score after 5 minutes between the experimental group and control group of IVH-PVH prematures, t= 0,121. There is no statistically significant difference in mean gestation age between the experimental group (30,74 weeks) and control group (29,97 weeks) of IVH-PVH prematures, t= 1,299. There is no statistically significant difference in mean birth weight between the experimental group (1479,44 grams) and control group (1379,37 grams) of IVH-PVH prematures, t= 0,913. Antenatal corticosteroid treatment of premature infants reduced the incidence of IVH-PVH significantly. There is no statistically significant difference in Apgar score after 5 minutes, mean gestation age and mean birth weight between the experimental and control group of IVH PVH prematures.

Wolf-Hirschhorn Syndrome: Report of two Cases in Bosnia and Herzegovina Wolf-Hirschhorn syndrome (WHS) is a rare developmental disorder caused by a partial deletion of the short arm of chromosome 4 (4p-). The main phenotypic characteristics of WHS are: intrauterine growth retardation, mental retardation, typical facial dysmorphism, microcephaly and midline fusion defects (cleft lip or palate, cardiac septal defects). Other abnormalities, such as agenesis of the corpus callosum, dysplastic kidneys, iris coloboma and skeletal abnormalities have occasionally been described. We describe two female newborn babies with a 4p deletion, who have a majority of the main phenotypic features of WHS. Prenatal diagnosis of the syndrome is very important, because dysmorphologic features are associated with profound mental retardation. Postnatal recognition of the syndrome requires genetic counseling of the parents and supportive multidisciplinary treatment.
