There has never been a case of dirofiliriasis conjunctivae recorded in Bosnia and Herzegovina until now. It is true that German scientists described one case in the woman who stayed in the region of former Yugoslavia, Italy and Spain in 1984 and she might have been infected in one of these countries. The aim of this work is to present the first case of ocular Dirolfiliriasis in a female patient in Tuzla. Patient BD, born in 1946 was admitted to Ophthalmology department in Tuzla on May 10th 2007 with a diagnosis of: Conjunctivitis oc.dex., parasitosis subconjunctivae dex. On May 11th 2007 a parasite was removed, 105.6 mm long, 0.473 wide with cephalic part slightly curved and esophagus length of 15mm. It was concluded that the discovered parasite is the member of Filaridae family and Dirofilaria species. Eoosinophilia with 17% eosinophiles was found in the peripheral blood smear. The presented case indicates that Dirofilariosis can be found in the region of Bosnia Herzegovina.

Since its foundation in 1992, the Croatian Medical Journal (CMJ) has followed the strict standards of quality in the scientific publishing. However, the Journal has been aware that its specific position demands more than just following the already established rules. From the very beginning, the Journal declared an “author-helpful policy,” stating that “journal editors should have a major role in training authors in science communication, especially in smaller and developing scientific communities. Journal authors usually send scientifically acceptable but poorly prepared articles and it is a pity to lose valid data because of their poor presentation.” (1,2). In brief, the editors and editorial staff of the CMJ have been well aware that the skills of scientific reporting and publishing in our academic community are not developed and that valuable research results and valid data are being lost because of poor presentation. To be perfectly honest, ten years ago this statement looked like a nice promise, one of the many we in academic medicine learnt not to take too seriously.

Hepatitis C infection is important global health problem with wide spectrum of health, social and economic consequences. The goal of this research was to estimate prevalence of hepatitis C virus infection in risk groups, and to determine association hepatitis C virus (HCV) infection and risk factors. Research included 4627 subjects divided in two groups. Test group included 2627 subjects divided in 4 subgroups with risk for HCV infection: those who received blood transfusion without screening on HCV (it was introduced in 1995) (700); intravenous drug users (60); patients on hemodialysis (168) and health care workers (1699). Control group included 2000 healthy volunteer blood donors. In all subjects anti-HCV antibodies were tested with third generation ELISA test. Positive serum samples were tested for presence of HCVRNA, using reaction of reverse transcription and polymerase chain reaction. In all anti-HCV positive subjects further epidemiological and clinical workup was performed. Prevalence of HCV infection in risk groups was: 4.6% in subjects who have received blood transfusions without HCV blood screening, 35% in intravenous drug users, 58.9% in patients on chronic dialysis, and 0.4% in health care workers. In control group prevalence was low (0.2%). In the group of 158 anti-HCV positive subjects, 73.4% had HCVRNA. The largest number of subjects with HCV infection was in the age group of 30-49 years (45.8%). This study showed that multiple blood transfusions before introducing the blood screening for HCV, longer duration of intravenous drug abuse, longer duration of hemodialysis treatment, larger number of accidental injuries in health care workers are independent and statistically significant risk factors for those groups examined. Results of this study confirm that general screening for HCV infection is recommended in risk groups for HCV infection in order to identify to prevent and to treat it.

PURPOSE It is estimated that 10-20 % patients on hemodialysis therapy have hepatitis C virus infection with big geographic and individual variability in HCV prevalence between different hemodialysis centers. OBJECTIVES To determine prevalence of HCV infection among hemodialysis patients in Hemodialysis Unit of General Hospital Gracanica and to make epidemiological, clinical, biochemical and virusological analysis in anti-HCV positive patients. WORK METHODS: 58 patients that were hemodialyse during 2000 year in Hemodialysis Unit Gracanica were included in this study. All patients were tested on anti-HCV antibody and further planed analyses were done. WORK RESULTS Prevalence HCV infection in Dialysis Unit Gracanica was 46.5 %. The most number of HCV positive patients were in age of 40-49 years 40.7 % or (11/27 patients). The more often HCV positive patients were male 59.3 % or (16/27 patients). In group of anti-HCV positive patients, in 85 % (23/27) have detected HCV RNA. It means that 39.60 % patients in Hemodialysis Unit Gracanica have chronic HCV infection, but 6.80 % patients had past infection. Receiving of blood transfusion, as risk factor, for HCV infection were more often found in group anti HCV + patients (81.5 %) than in group anti-HCV negative patients (51.6 % patients). The length of dialysis therapy were longer in group anti HCV + patients and it was 6.8 years than in group of anti-HCV negative patients that was 1.6 years. HCV infection was not associated with significant biochemical parameters of liver lesion or with manifested clinical symptoms in the time of this study. CONCLUSION The observed Unit for Hemodialysis can be concerned as unit with high prevalence of HCV infection. It is courage fact that there was no new registered HCV seroconversion since beginning of work this unit until time of this study. Implementation of general and specific measures for prevention of HCV infection and introduction of regular control can decrease risks for HCV infection inside hemodialysis unit.

Objectives  Hepatitis C virus (HCV) infection is spread worldwide with significant geographical differences in the prevalence and genotypes. The aim of this study was to analyse HCV infection in hemodialysis (HD) units in Bosnia and Herzegovina (BH), through genotypes and routes of transmission. Design and Methods  We analysed data from Renal Registry of BH for the years 2002 and 2003 in order to estimate prevalence and incidence of anti-HCV positive patients in 23 HD units in BH (ELISA III). Then we tested 88 anti-HCV positive patients from Tuzla for HCV RNA using reverse transcription polymerase chain reaction (Amplicor Roche diagnostic commercial test) and genotype with method of reverse hibridization of amplified sample material (Innolipa HCV II commercial test). Results  In 2002 we registered a prevalence of 39.1 and an incidence of 3.1% of anti-HCV positive HD patients in 23 HD units, and in 2003 a prevalence of 29.3 and an incidence of 2.04% in 24 HD units. Prevalence of anti-HCV positive patients was significantly different in HD units, from 14.3 to 69.1%. From 88 tested anti-HCV positive HD patients in Tuzla HD unit, we found 76 HCV RNA positive patients (87.36%). The genotype of HCV was analysed in 59 of these patients and we found, unusual for Europe, genotype 4 in 37 (62.7%), genotype 1b in 17 (28.8%) and 1a in five patients (8.5%). A total of 61% of seroconversions happened in 1999, 2000 and 2001. In 2001, we separated dialysis machines for anti-HCV positive and anti-HCV negative patients, and in 2003 we had nine seroconversions (genotype 4 in five patients). These patients had no blood transfusions. Conclusions  Prevalence and incidence of anti-HCV positive hemodialysis patients is still high in BH and origin of genotype 4 HCV is not clear. Nosocomial spreading of HCV plays a significant and probably the most important role in transmission of HCV in HD units.

: The presence of waterborne enteric pathogens (bacteria, viruses and protozoa) in potable water represents a potential danger for people's health. While doing a microbiological examination of potable water on a regular basis, we obtain a constant control of presence of the bacteria that contaminate water. However, the water examination of the enteric viruses is done only when we have some large-scale hydrous epidemics. Finding the bacteria wich point to fecal contamination of drinking water is not a safe indicator of presence of the enteric viruses. After a two step RT/PCR examination on viruses in 84 samples of potable water, the enteroviruses were found in 53 out of 84 samples (63.09%), while the hepatitis A virus was not found after one step RT/PCR examination. In conclusion, we emphasize the need of standardizing the method of potable water viruses detection, in order to legalize the need of its regular application.
