Infections caused by viruses hepatitis B and C are one of the most severe problem in contemporary medicine. These viruses show high affinity to hepatocytes. The fundamental pathogenetic mechanisam which is responsible for hepatocyte damage, depends either on cytocidal effect of virus or immunological response of the infected host. The most common way of virus transmission nowdays is parenteralno, due to intravenous drug abuse, while earlier the blood transfusion was a more often the pathway of infection. Patients on chronical hemodialysis are at increased risk of HCV infection. The aim of our study was to determine the most common risk factors and pathways of HBV and HCV infection, as well as to assess the significance of the serological markers of hepatitis B and hepatitis C viruses in risk groups of patients. The study was conducted at Institute for blood transfusion at Health Center of Kosovska Mitrovica, in the period from January 2000 until December 2015. ELISA test was performed for the confirmation of presence of hepatitis B and hepatitis C viruses in the blood. The results showed that the number of respondents increased significantly during the research period. Voluntary blood donors were significantly more represented than respondents who were referred by a physician. Average age of all seropositive? examinees in the study was 47,1 ± 18,1 years (range from 8 – 79 years). HBV seropositivity was significantly more present compared to HCV seropositivity. The highest incidence of HBV and HCV infection was recorded in the working age population, between 40 and 50 years of age. Analyzing the data of the way of infection transmission, most patients reported an unknown pathway of infection (39%). The second most common way of infection transmission was hemodialysis (28.4%), while the intravenous drug abuse was noted in 13,4% of patients. We can conclude that the implementation of regular screening and timely prevention, as well as the education program of the population can be helpful in reducing the number of patients with HBV and HCV infection

Hronični B virusni hepatitis (HHB) i dalje predstavlja veliki zdravstveni svetski problem uprkos obaveznoj i univerzalnoj imunizaciji protiv infekcije hepatitis B virusom (HBV). Kod određenog broja bolesnika hronična hepatitis B virusna infekcija u prirodnom toku bolesti progredira ka cirozi i hepatocelularnom karcionomu te je primarni cilj antivirusne terapije HHB zaustavljanje progresije bolesti. Danas na tržištu postoje dve grupe lekova za lečenje HHB: a)imunomodulatorna terapija konvencionalim interferonom alfa (INF) i pegilovanim interferonom alfa 2 a ( PEG-INF), b) peroralna antivirusna terapija analozima nukleot(z)ida. Lamivudin je dugo bio jedini medikament na našem tržištu za lečenje HBV te je kod većine naših pacijenata došlo do razvoja rezistencije. Od pre dve godine, na tržištu Srbije se registruje novi oralni analog iz grupe nukleotida : tenofovir disoproksil fumarat (TDF). U radu smo analizirali 69 bolesnika sa hroničnim hepatitisom B lečenih u Klinici za Infektivne i tropske bolesti KCS Beograd u periodu od 2012 do 2014 godine. Svi bolesnici uključeni u ovo istraživanje prethodno su bili lečeni LAM, a nakon razvoja rezistencije na LAM, primenjivan je TDF. TDF je pokazao odličnu efikasnost, visoku barijeru za rezistenciju i vrlo malo neželjenih efekata u višegodišnjoj primeni. Naša iskustva sa primenom ovog leka nisu dugotrajna imajući u vidu njegovu krakotrajnu dostupnost na našem tržištu.

Introduction: Toxoplasma gondii is one of the causative agents from the groups of TORCH infections, which are commonly associated with congenital anomalies. Objective: Defining risk factors for infection byToxoplasma gondii of women in reproductive ages in the territory of Kosovska Mitrovica, as well as determination of seroprevalence of infection by Toxoplasma gondii in prenatal screening of pregnant women and women of childbearing age. Materials and Methods: Across sectional study that included 49, pregnant women and women of childbearing age has been conducted. The pregnant women have been monitored on regularly base, or some women have been treated in the Gynecology and Obstetrics Department of the Health Center in Kosovska Mitrovica. Ages, place of residence, education, gynecological history and exposure to the potential risk factors associated with Toxoplasma have been collected by questionnaires. Sera have been tested on the presence of IgM and IgG antibodies to Toxoplasma gondi by ELISA standard manufacturer's protocol (Euroimmun, Luebeck, Germany). Results: Our study shows that 32 (65.3%) women were seronegative, while 17 women (34.7%) were seropositive. Significant seropositivity has been recorded for the women who were in contact with the ground (42.9%), compared to the women who did not have this contact (23.8%). Uses of undercooked meat in the diet did not show any effect to the seropositive status of the respondents, i.e. greater percentage of analyzed patients (75.5%) used inadequately cooked meat. Even 93.3% of respondents deny contact with a cat. It is observed that seropositivity increased with the age. Conclusion: Seroprevalence to Toxoplasma gondii infection of women of childbearing in the territory of northern Kosovska Mitrovica is not high, which implied that there is a higher possibility for acquiring primary toxoplasmosis infection during pregnancy especially for women who come in contact with the ground

Febrile seizures are the most frequent neurological disorder in the childhood. According to American Academy of Pediatrics (AAP), they have been defined as seizures provoked by high temperature in children aged between 6 months and 5 years, without previous history of afebrile seizures, intracranial infections and other possible causes of seizures. Seizures can be typical and atypical, according to the characteristics. Pathogenesis of this disorder has not been clarified yet, and it is believed to be a combination of genetic factors, high body temperature and brain maturation. The risk factors for recurrence of febrile seizures are: age in which seizures appeared for the first time, epilepsy in the first degree relative, febrile seizures in the first degree relative, frequent diseases with fever and low body temperature on the beginning of seizures. The frequency of recurrent seizures The risk for occurrence of epilepsy in children with simple seizures is about 1-1.5%, which is slightly higher compared to general population, while it increases to 4-15% in patients with complex seizures. However, there is no evidence that therapy prevents occurrence of epilepsy. When the prevention of recurrent seizures is considered, it is necessary to separate simple from complex seizures. The aim of this paper was to analyze the most important risk factors for febrile seizures, and to evaluate their impact on occurrence of recurrent seizures. Our study included 125 children with febrile seizures, aged from 6 months to 5 years. The presence of febrile seizures and epilepsy in the first degree relative has been noted in 22% of children. Typical febrile seizures were observed in 76% of cases, and atypical in 24%. Most patients had only one seizure (73.6%). Children, who had seizure earlier in life, had more frequent recurrences. Both risk factors were present in 25% of patients, while 68% of patients had only one risk factor. For the children with febrile disease, primary risk factors were the level of body temperature and a family history of febrile seizures. The risk for febrile seizures in these children was 10,4%, which is more than a twice as high compared to general population, which is 4%. Is between 10% in children without risk factors and 50-100% in children with three or more risk factors.

Post-streptococcal glomerulonephritis (PSGN) is a frequent cause of acute nephritis in children. This case study was done with the aim to point out that the infections caused by Group A streptococci, in spite of antibiotic era, are still present in the population. An 8-year old boy was admitted in our hospital with a two-day history of fewer, tonsillopharyngitis. After hospital admission, patient was treated with penicillin during the period of 10 days, antihypertensive medications (captopril, furosemide), including restricted diet of salt. After the treatment, patient became better. On demission it was found proteinuria and microhematuriaPSGN is very serious disease, which leaves severe complications if the valid therapy with penicillin is not used in propriety time, during the recommended period of 10 days.
