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.

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.
