OBJECTIVE The aim of the study was to determine the epidemiological characteristics of bacterial meningitis observed in neonates born in the Department of Gynaecology and Obstetrics, University Clinical Centre Tuzla, Bosnia and Herzegovina, admitted to Intensive care unit (NICU) or readmitted, because of suspected infection, after discharge from the nursery. SUBJECTS AND METHODS This study was carried out from July 1, 2012 to June 30, 2013. During this period 4136 neonates were born. All neonates admitted to the Intensive care unit with signs and symptoms of systemic infections, and neonates readmitted to the Intensive care unit, after discharge from the nursery for sepsis work up were included in the study. RESULTS Eighteen of 200 neonates (9%) admitted or readmitted to the NICU developed meningitis. 61% cases were late onset meningitis. The overall incidence was 4.4/1000 live births. The mortality rate was 11.1%. The mean age of symptom presentation was 8.7 days. The most common clinical features were: fever, respiratory distress and jaundice. Significant risk factors for acquiring meningitis were: male gender, Caesarean delivery, stained amniotic fluid. Positive CSF finding were detected in 6/18 (33.3%) of cases. Gram-positive bacteria were more frequently responsible for confirmed meningitis. In all neonates with meningitis blood culture was examined and 5 (50%) yielded Gram-negative bacteria. CONCLUSION The high rates of neonatal meningitis with predominant late onset may suggest nosocomial origin. Measures to improve antenatal, intrapartum and delivery care and measures during NICU hospitalisation are necessary to lower the risk of nosocomial infections.

OBJECTIVE The aim of this study was to determine the effect of psychosocial factors on the age at menarche of girls in Federation of Bosnia and Herzegovina (FBH). SUBJECTS AND METHODS A cross-sectional study was conducted from September 2002 to May 2003 in all Cantons of the FBH. The random stratified sample included 19.803 girls aged 9.0 to 17.5 years. Data were collected using the status quo method. Probit analysis was used to estimate median age at menarche and 95% confidence intervals. RESULTS The present study shows that menarche occurred significantly earlier (p<0.05) in girls from dysfunctional families (median: 12.99 years, 95% confidence interval: 12.93-13.05) than in girls who grew up in intact families (median: 13.04 years, 95% confidence interval: 13.01-13.07). Analyzing separately the impact of each of family stressors on age at menarche, we found that menarcheal age was significantly lower in girls from single-mother families, whose parents are divorced, whose one parent is died and where alcoholism in family is present than in girls from intact families. Maturation was found to be earlier in girls from dysfunctional families then in those from intact families after the influence of place of residence and sibship size was eliminated. CONCLUSION From our research we can conclude that the girls from dysfunctional families reached earlier age at menarche than their peers who grew up in normal families, and that this effect did not disappear after controlling for socioeconomic variables.

Quantum key distribution (QKD) is based on the laws of quantum physics and therefore it can guarantee the highest level of security. It is used to establish the key that is used for further symmetrical encryption. Since QKD consists of several phases in which the key is reduced, it is necessary to define the equation by which the length of the raw key is calculated. In this paper, we analyse all QKD phases with an emphasis on the explanation of the process of shortening the initial key. The results are verified with a large number of tests using a quantum cryptography simulator. DOI: http://dx.doi.org/10.5755/j01.eee.21.6.13768
