Background: The corona virus is transmitted in three ways: by direct contact with an infected person, by droplets, and by air. Transmission control according to official guidelines can be prevented by keeping a distance, wearing a mask and washing hands. Sharing a space with several members of the immediate or extended family increases the risk of transmission in all three ways. In Traditional Bosnian families two or three generations live in one household. The family doctor is informed with living conditions of the residents and has the opportunity to monitor the rate of secondary transmission from the index case, and then recommend additional preventative and treatment measures., Objective: The aim of the study was to determine the first occurrence of the symptoms and to monitor possible intrafamilial transmission of the disease through clinical examinations and microbiological-serological tests., Methods: The study was conducted in a family medicine clinic in the region of northeastern Bosnia and Herzegovina from March to December 2020. Patients with symptoms that could indicate the presence of COVID-19 disease were registered. If COVID-19 was proven, the patient became an index case. The other members of the family would be monitored for the secondary transmission via laboratory (PCA SARS-CoV-2 and IgM and IgG antibodies) and clinical parameters., Results: Characteristics of 25 index cases were analyzed. All 25 of them were middle-aged men that worked outside the home. In 25 households, there was a total of 123 members that shared a home with the index patient. Secondary transmission developed in 76 out of 123 family members (61.8%). Only one patient had a severe form of the disease and was hospitalized. 2 patients died., Conclusion: Intrafamiliar transmission of Covid-19 in households of Bosnia and Herzegovina is high. The secondary attack rate of SARS- CoV-2 in households is 61,8%. In the surveyed households, family members use common rooms with an infected patient, and the customs of family gatherings are maintained, without the implementation of protective measures. The family medicine team has the opportunity to apply appropriate preventive action, education and early prehospital treatment as well as adequate selection for the hospital admission., Competing Interests: None declared., (© 2021 Nizama Salihefendic, Muharem Zildzic, Haris Huseinagic, Sead Ahmetagic, Dzenita Salihefendic, Izet Masic.)

Introduction: Cytomegalovirus (CMV) infection is ubiquitous. It affects all age groups, and its clinical picture ranges from mild to severe, especially as a congenital infection in neonates., Aim: To determine frequency of CMV infection in pregnant women in Tuzla Canton (TC) and the risk factors that lead to the infection., Methods: This prospective study included 300 pregnant women from TC aged 18 to 42 years. CMV serology was performed on all participants, and in case of acute infection additionally IgG avidity test. Participants also completed the questionnaire on the risk factors for CMV infection., Results: The median age of the 300 women was 28 ±4.97 years. There were 161participants (53.6%) who classified their environment as urban and 295 (98.33%) were married. More than half of the women had completed secondary school 168 (56%). Positive IgG antibodies to CMV had 280 (93.0%) women. Positive IgM and IgG antibodies had 9 (3.0%) participants, but all of them had high IgG avidity, which indicates reinfection or recurrent CMV infection. There was a statistically significant higher number of seropositive participants living in rural areas than those living in urban areas (p= 0.048). Also, there was significantly higher percentage of positive anti-CMV IgG in pregnant women with lower education (p=0.04)., Conclusion: In our region there is high seropositivity rates of IgG antibodies to CMV in pregnant women. No case of primary CMV infection was proven. The risk factors for CMV infection have been proven to be rural environment and lower level of education.

Introduction: Chronic HCV infection is chronic inflamatory liver disease caused by hepatitis C virus. Anti HCV prevalence among intravenous drug users (IVDU) is very high and it accounts 40% -90% (60%-90%) with the risk of 80% of developing the chronic infection., Aim: The aims of this study were: a) to compare clinical characteristics of chronic HCV infection among IVDU and non-users population and to detect their impact to treatment outcome; b) to investigate the treatment efficacy comparing sustained viral response (SVR) in these two populations in Tuzla Canton., Patients and Methods: The study was retrospective-prospective and included 45 IVDU of both sexes from Tuzla Canton which were treated from chronic HCV infection with Pegilated interferon 2a/2b + ribavirin in the Clinic for Infectious Diseases and Clinic for Internal Disease of University Clinical Centre in Tuzla. The control group were presented by non-users who completed therapy in both Clinics. For statistical analyses it was used statistical package SPSS 20,0 (SPSS Inc, Chicago, IL, USA) with tests of descriptive statistics with measures of central tendency and dispersion. Quantitative variables were tested by t-test or by Mann-Whitney test. Qualitative variables were tested by hi-square test or by Fisher's test. The standard analyse of level's risk was used too. The analyse of predictive value of EVR for achieving the ETR and SVR was done by cross-tabulation. The impact of known factors for achieving the SVR was evaluated by logistic regression analyses. All tests were done with statistical level of significance of 95% (p=0,05)., Results: Men were more dominant in the test group (93,3% / 61,7%), also younger age (p<0,001) and lower BMI (p=0,019). The test group had significant higher basal values of Le, Hb, Plt and ALT and tendency to lower stages of fibrosis (p=0,08). The difference in genotype frequencies was statistically significant (p=0,001) with clearly dominance of G3 and G4 among IVDU. Treatment was not complited by two patients in both groups (4,4% /3,3%). EVR was significantly higher in test group (p=0,001) so did the ETR (p=0,002) and SVR (p<0,001). Predictive factors for SVR were: age (negative predictive factor), male sex, absence of reduction of pegilated interferon and ribavirin, Metavir stage of fibrosis and presence of EVR., Conclusion: Population of IVDU were adherent to treatment protocol and with excellent treatment response they justified the hope of health care workers for success treatment of this population.

Objective: The use of commercially available noninvasive markers for chronic hepatitis B (CHB) related fibrosis is not widely available in developing countries so clinicians in those countries frequently use free alternatives. We aimed to create an optimized algorithm for selection of patients with the highest probability for presence/absence of significant liver fibrosis and cirrhosis based on the use of multiple free scores., Methods: We evaluated six free noninvasive markers for CHB related fibrosis against liver biopsy and selected the best thresholds for prediction/exclusion of significant fibrosis and cirrhosis in CHB patients. Algorithm based on four scores and their corresponding thresholds was created., Results: The calculator based on developed algorithm can be found at http://www.chb-lfc.com. We evaluated 211 patients in main group and 65 patients in external validation group. We selected four scores for creation of combination algorithm. The algorithm was able to classify 123/211 (58.3%) patients with a 93.5% accuracy of correct classification for prediction of presence/absence of significant fibrosis in main group. In validation group, the algorithm was able to classify 48/65 (73.8%) of patients with 93.8% (45/48) overall accuracy. When used to predict presence/absence of cirrhosis, the algorithm was able to correctly classify 181/211 (85.8%) and 59/65 (90.8%) of patients in main and validation group, respectively, with an overall accuracy of 97.8% and 98.3%, respectively., Conclusion: Developed algorithm based on routine laboratory tests is a usable, applicable and accurate tool for diagnosis of CHB related fibrosis and cirrhosis, suitable for resource-limited settings where more expensive modalities are unavailable., (Copyright © 2015 European Federation of Internal Medicine.

Acute respiratory distress syndrome (ARDS) is a form of acute life threatening respiratory failure. In daily practice there is difficulty in diagnostic and therapeutic management of Acute respiratory distress syndrome (ARDS). We observed delay in diagnostic and therapeutic procedures in patients with clinical signs for the presence of severe respiratory disorders. Finding timely evidence of the presence the clinical signs of threatening ARDS and underlying diseases like influenza A/H1N1 during prehospital period in early stage of disease it is possible introduce early adequate treatment: high flow oxygen, fluid replacement and pharmacological and antiviral therapy. This measure can reduce high mortality in patients who develop ARDS. It is important to improve diagnostic criteria for a precise definition of ARDS and transfer it in practice of emergency and family medicine, microbiology, intensive care units, hospital departments of infectious and respiratory diseases. In this article we underlined the key elements of the new definition of ARDS, diagnostic criteria and the importance of early diagnosis in prehospital period following clinical feature and course (a presence of severe dyspnea) by adding chest x-ray and laboratory investigations.

Introduction: More than three decades after recognition of acquired immunodeficiency syndrome (AIDS) in the United States, the pandemic of human immunodeficiency virus (HIV) infection has dramatically changed the global burden of disease., Aim: The main goal of this research is retrospective analysis of epidemiological and clinical characteristics of 28 HIV infected patients, who were diagnosed and treated at the Clinic for Infectious Diseases in University Clinical Center Tuzla in the period from 1996 until the end of 2013., Subjects and Methods: Retrospective analysis was performed using the medical records of 28 HIV-infected persons. Two rapid tests were used for HIV testing: OraQuick Advance test, Vikia HIV1/2, Elisa combo test, HIV RNA test. AIDS disease was determined by using the criteria from WHO., Results: Among a total of 28 HIV-infected persons, 23 (82.14%) were males and 5 (17.86%) were females, with the male: female ratio of 4,6:1. In terms of the transmission route, a large proportion of cases were infected through heterosexual contact 19 (67.86%). At the time of the first visit, 16 (57.15%) patients showed asymptomatic HIV infection, 4 (14.28%) HIV infection with symptoms other than the AIDS defining diseases, and 8 (28.57) had AIDS. At the time of first hospital visit, the CD4 + cells count ranged from 40 to 1795/µl (conducted in 19 patients), and mean value of CD4 + cells was 365,31/µl, and mean HIV RNA titer was 287 118 copies/ml³. Of 28 HIV-infected persons 39 cases of opportunistic diseases developed in 12 patients (42.9%). In terms of the frequency of opportunistic diseases, tuberculosis (12 cases, 42.9%). Among a total of 28 HIV-infected patients, 6 (21.4%) of them died., Conclusion: This study characterizes the epidemiological and clinical patterns of HIV-infected patients in Tuzla region of Bosnia and Herzegovina to accurately understand HIV infection/AIDS in our region, in the hope to contribute in the establishment of effective HIV guidelines in the Tuzla region of B&H in the future.

Introduction: Acinetobacter baumannii is a frequent cause of infections in hospitals around the world, which is very difficult to control and treat. It is particularly prevalent in intensive care wards., Aim: The main objective of the research was to establish the application of epidemiological monitoring of nosocomial infections (NIs) caused by A. baumannii in order to determine: the type and distribution of NIs, and to investigate antimicrobial drug resistance of A. baumannii., Material and Methods: 855 patients treated at the Clinic of Anesthesiology and Reanimation, University Clinical Center Tuzla during 2013 were followed prospectively for the development of NIs. Infections caused by A. baumannii were characterized by the anatomical site and antibiotics resistance profile., Results: NIs were registered in 105 patients (12.3%; 855/105). The predominant cause of infection was A. baumannii with an incidence of 51.4% (54/105), followed by ESBL-producing Klebsiella pneumoniae with 15.2% (16/105) of cases, methicillin-resistant Staphylococcus aureus with 8.6% (9/105), and ESBL-producing Proteus mirabilis with 7.6% (8/105). According to the anatomical site, and type of NIs caused by A. baumannii, the most frequent were respiratory infections (74.1%; 40/54). Infections of surgical sites were registered in 11.1% (6/54) of cases, while bloodstream infections in 9.2% (5/54). A. baumannii isolates tested resistant against most antibiotics examined, but showed a high degree of susceptibility to tobramycin (87%; 47/54) and colistin (100%; 54/54)., Conclusion: The increasing incidence of multi- and extensively drug-resistant Acinetobacter spp. emphasizes the importance of administration of an adequate antibiotic strategy and the implementation of strict monitoring of the measures for controlling nosocomial infections.

Introduction: Intensive care units (ICUs) are associated with a greater risk of developing nosocomial infections (NIs) than other departments., Aim: The aim of this study was to determine the rate, the site and causative organisms of NIs in the surgical ICU at University Clinical Center Tuzla., Methods: All patients admitted to the surgical ICU were followed prospectively, for the development of NIs (January-December 2010). Determination of NIs was performed using standardized the Centers for Disease Control and Prevention (CDC) criteria., Results: 94 out of 834 patients (11.27%) developed NIs. Respiratory tract infections were seen in 56 (60%), urinary tract infections in 15 (16%) and gastrointestinal tract infections in 8 (9%) patients. Other infections identified were surgical site, bloodstream and skin infections. Gram-negative organisms were reported in approximately 75% of cases (78.7% extended-spectrum beta-lactamase (ESBL)-producers). Klebsiella pneumoniae was the commonest (51.0%), followed by Proteus mirabilis (21.3%) and Pseudomonas aeruginosa (10.6%). Methicillin-resistant Staphylococcus aureus (MRSA) (16%), and Clostridium difficile (9.6%) were the commonest among gram-positive bacteria., Conclusion: Respiratory and urinary tract infections made up the great majority of NIs. ICU patients are more susceptible to NIs, emphasizing the importance of continuous surveillance and enforcement of specific infection control measures.

Objective: We aimed to compare the features of intensive care units (ICUs), their antimicrobial resistance patterns, infection control policies, and distribution of infectious diseases from central Europe to Mid-West Asia., Methods: A cross-sectional point prevalence study was performed in 88 ICUs from 12 countries. Characteristics of ICUs, patient and antibiotic therapy data were collected with a standard form by infectious diseases specialists., Results: Out of 749, 305 patients at least with one infectious disease were assessed and 254 patients were reported to have coexistent medical problems. When primary infectious diseases diagnoses of the patients were evaluated, 69 had community-acquired, 61 had healthcare-associated, and 176 had hospital-acquired infections. Pneumonia was the most frequent ICU infection seen in half of the patients. Distribution of frequent pathogens was as follows: Enteric Gram-negatives (n = 62, 28.8%), Acinetobacter spp. (n = 47, 21.9%), Pseudomonas aeruginosa (n = 29, 13.5%). Multidrug resistance profiles of the infecting microorganisms seem to have a uniform pattern throughout Southern Europe and Turkey. On the other hand, active and device-associated infection surveillance was performed in Turkey more than Iran and Southeastern Europe (p < 0.05). However, designing antibiotic treatment according to culture results was highest in Southeastern Europe (p < 0.05). The most frequently used antibiotics were carbapenems (n = 92, 30.2%), followed by anti-gram positive agents (vancomycin, teicoplanin, linezolid, daptomycin, and tigecycline; n = 79, 25.9%), beta-lactam/beta lactamase inhibitors (n = 78, 25.6%), and extended-spectrum cephalosporins (n = 73, 23.9%)., Conclusion: ICU features appears to have similar characteristics from the infectious diseases perspective, although variability seems to exist in this large geographical area., (Copyright © 2013 The British Infection Association.

Introduction: Hospital-acquired Urinary tract infections make 35% of all the hospital-acquired infections, and about 80% of them are related to the catheterization of the urinary bladder., Purpose: To determine clinical characteristics and dominant etiologic factors of Urinary Tract Infections associated with urinary catheter (C-UTIs)., Methods: Determined clinical characteristics of C-UTIs were prospectively analyzed on 38 hospitalized patients in the Clinic for Infectious Diseases at the University Clinical Centre Tuzla, from January 1(st) 2011 to December 31(st) 2011. The control group constituted of 200 patients with community-acquired Urinary Tract Infections (Co-UTIs) hospitalized in the same period., Results: It was registered on 22 (57.89%) of symptomatic infections, 14 (36.84%) asymptomatic bacteriuria and 2 (5.26%) other C-UTIs. Dominant etiologic factors were: E. coli, caused 14 (36.84%), Extended-Spectrum Beta-lactamase producing (ESBL) Klebsiella pneumoniae 7 (18.42%), Enterococcus faecium and Candida spp. 3 (7.89%) of C-UTIs. E. coli was significantly most common etiologic factor of C-UTIs in younger women (p=0.04). E. coli from C-UTIS showed significantly higher resistance to antimicrobial drugs. Inadequate antimicrobial therapy was significantly more common prescribed to patients from C-UTIs. Lethal outcome was significantly most common associated with certain clinical and laboratory findings., Conclusion: Initial antimicrobial therapy of those serious infections should be based on data from those research.

Introduction: Bacterial meningitis is one of the most serious infectious diseases in childhood., Aim: To identify the most common causes of bacterial meningitis in children in Tuzla Canton., Patients and Methods: This is a retrospective study which included 140 children, aged from 1 month to 14 years, treated at the Clinic for Infectious Diseases Tuzla, in the period 1999-2009, who had clinical and laboratory parameters of bacterial meningitis., Results: In Tuzla Canton in ten year period were registered 140 cases of bacterial meningitis in children aged 1 month to 14 years. Prevalence was 1.53/1000. The average age of patients was 3.6 +/- 3.8 years. Male to female ratio was 1.3:1. April, May and November were the months with the most reported cases of bacterial meningitis (p = 0.02). Most affected were children 1-12 months of age (p < 0.001). The most common pathogens of bacterial meningitis were Haemophilus influenzae (13.6%), Neisseria meningitides (8.6%) and Streptococcus pneumoniae (5.7%) (p < 0.001). Mortality was 2.14%., Conclusion: Bacterial meningitis is present in Tuzla Canton, and three major pathogens are Haemophilus influenzae, Neisseria meningitis and Streptococcus pneumoniae. The most affected were children 1-12 months of age, and most cases of bacterial meningitis occurred in spring.

Aim: To determine the etiology of peritonitis, as well as the sensitivity of isolated bacteria to antibiotics., Methods: Study was performed at the Surgical Clinic, Department of Anesthesiology and Reanimation, Department of Microbiology, Department of Clinical Pharmacology of University Clinical Centre (UCC) Tuzla. In a prospective study, starting from 1.6.2009. to 30.6.2010., was 60 patients analyzed who underwent surgery for acute peritonitis in the Surgical Clinic, UCC Tuzla., Results: After microbiological processing of the content of the operative field, wound swabs and smears of drainage, we isolated Gram positive coccid bacteria: Coagulase-negative Staphylococcus in 18.36%, Staphylococcus aureus in 12.6%, while Enterococcus faecalis and Enterococcus faecum were found in 3.44% isolates. In the group of Gram-negative bacteria we isolated: Escherichia coli in 15.51%, and Pseudomonas aeruginosa and Klebsiella pneumoniae in 10.34% of the cases. The sensitivity of coagulase-negative Staphylococcus was largest to vancomycin (100%), and lowest to penicillin (10%) and Staphylococcus aureus sensitivity was largest to vancomycin and amoxicillin-clavulanate (100%) and lowest to penicillins (3.7%). Sensitivity of the facultative anaerobic Gram-negative bacilli was highest to carbapenems 95-100%, and lowest to penicillin preparations 0-56%., Conclusion: Based on the results of microbiological findings of 83.33% patients empirical antibiotic therapy was appropriately involved, and in 16.67% was inadequate and later changed, following the results of microbiological findings. This study indicates the importance and validity of microbiological diagnostics to determine the etiology of peritonitis and appropriate selection of antibiotics to treat these infections, with the required surgical treatment.

Conflict of Interest: none declared., Goal: The goal of the research is to determine the relationship between frequency and reporting of stab incidents, attitudes and knowledge about stab incidents and occupational risk for transmission of viral infection with HBV, HCV or HIV among health care professionals employed in primary health care., Material and Methods: Conducted is prospective, cross-section study by questionnaires in 2012. The survey included health professionals in Primary Health Care Center in Tuzla. The final sample has 131 respondents (85% women). Statistical analysis was performed using the statistical package SPSS version 20.0., Results: The prevalence rate of stab incidents throughout their career in our study was 66%; while the rate of reported incidents was 4.83 ˜ 5 times lower than the actual prevalence. In 49 out of 87 cases this was a case of hollow needle prick. The most common causes of stab incidents are the time pressure, unforeseen reactions of patients and lack of concentration., Conclusion: Stab incidents are often not reported in in developing countries. Training in order to raise awareness and knowledge about the problem, proper procedures, good organization of work and anti-stress program, safer disposal, conducting prophylaxis before and after exposure monitored by the relevant institutions of occupational medicine should contribute to solving this problem.

Introduction: Clostridium difficile (C. difficile) is currently the leading cause of healthcare-associated diarrhea, but almost nothing is known about the extent of C. difficile infection (CDI) in Bosnia and Herzegovina., Goal: We aimed to retrospectively analyze CDI in hospitalized patients at University Clinical Center (UCC) Tuzla, Bosnia and Herzegovina from January 2009 through June 2012., Methods: We analyzed all patients (except children ages 0-2), diagnosed with CDI based on anamnestic and epidemiological, clinical picture and microbiological tests (proof of toxins in the stool by enzyme-linked immunosorbent assay)., Results: From a total of 989 patients tested for C. difficile toxin (60.2 per 10,000 inpatient days) 347 (35.08%) were positives. The mean incidence rate of CDI was 2.23 per 10,000 inpatient days (range 1.32-2.87). Annual rates of hospitalization were 15.68 per 10,000 admissions (range 8.99-20.35). Most patients had a previously identified risk profile of old age, comorbidity and recent use of antibiotics. 41/276 (14.86%) patients had died, and 11/41 (26.82%) were CDI-associated deaths. Complicated CDI were registered in 53/276 (19.21%) patients, and recurrent infections in 65/276 (23.55%)., Conclusion: Our data suggest that CDI is largely present in our setting which represents a serious problem and points to the importance of international surveillance, detection and control of CDI.

Association of Gastroenterologists and Hepatologists of Bosnia and Herzegovina based on the experiences of domestic and foreign centers operating in the field of hepatology and accepted guidelines of the European and the U.S. Association for Liver Diseases adopted the consensus for the diagnosis and treatment of chronic viral hepatitis B and C. The guidelines are intended for specialists in gastroenterology and hepatology, and infectious diseases physicians working in primary health care and family medicine, but also other physicians who are confronted with this disease in their practice, with the aim of facilitating and shortening the diagnostic and treatment protocols of patients with chronic viral hepatitis B and C. This ensures faster, more efficient, more rational and cost-effective care of patients with hepatitis, with an emphasis on stopping the deterioration of liver disease to liver cirrhosis and eventually hepatocellular carcinoma. Key words: Chronic hepatitis B and

Introduction: The prevalence of human brucellosis in Bosnia and Herzegovina and the Tuzla Canton reached its peak in 2008, with a reported total of 994 cases within country, and with 104 cases within the Tuzla Canton., Aim: to analyze the clinical and epidemiological features of human brucellosis in patients hospitalized at the University Clinical Center Tuzla during the period from 01/01/2000 till the 31/12/2010., Methods: We retrospectively analyzed the clinical symptoms, the laboratory and X-ray findings, the treatments, and the course and outcome of the disease. The diagnosis of brucellosis was based on anamnesis, clinical presentation, in correlation with a positive blood-culture, and/or serological tests., Results: The majority of patients (93.18%) were from rural regions. There were more males (79.54%) than females. Most of the patients were aged between 30 to 39 years (21% cases). Contact with infected animals was registered for 83.40% of the patients. The main symptoms and signs were fever, joint-pains, night sweating, anorexia, headaches, and hepatosplenomegaly. The important laboratory findings were increased erythrocyte sedimentation rates, increased values of C-reactive protein, and anemia. Adult patients were treated with a combination of gentamicin or streptomycin with doxycycline, and the children with a combination of gentamicin, and trimethoprim-sulfametaxasol, over at least 6 weeks. Complications were documented in 20.45% of the patients. Relapses were observed in 14.20%, and a chronic form of brucellosis in 5.11% of patients. There were no cases with lethal outcomes., Conclusion: Brucellosis is a growing public health problem, not only within the Tuzla Canton, but throughout Bosnia and Herzegovina.

Background: Data on the epidemiology of hepatitis B and C in Bosnia and Herzegovina (B&H) are lacking., Objectives: To assess the prevalence of hepatitis B surface antigen (HBsAg) and anti-hepatitis C virus (anti-HCV) in blood samples of first time blood donors in a well-defined region of B&H. Our secondary goal was to estimate the prevalence of HBsAg and anti-HCV in the general population of the same region., Patients and Methods: We evaluated 8196 blood samples for the presence of HBsAg and/or anti-HCV, adjusted for differences in gender, and used the ratio estimation method to determine the prevalence in the general population., Results: We analyzed 1263 (15.4%) female and 6933 (84.6%) male blood donors (male-to-female ratio: 5.49 to 1). The adjusted prevalence of HBsAg among blood donors was 0.787% (95% CI = 0.535-1.038), while the prevalence of anti-HCV was 0.267% (95% CI = 0.016-0.519). There was no difference in the prevalence of HBsAg or anti-HCV between men and women. We estimate that the prevalence of HBsAg and anti-HCV in the general population is 1.057% to 1.535% and 0.29% to 0.89%, respectively., Conclusions: The prevalence of HBsAg and anti-HCV among blood donors suggests that our region has low endemicity for both hepatitis B and hepatitis C.

Introduction: Intrahospital infections in surgical wards pose a significant problem, particularly in patients with impaired natural defense potential. They significantly complicate and increase the cost of basic treatment of the patient and sometimes leave permanent damage. Active control of their appearance is of paramount importance in their prevention., Goal: By this study we try to determine the frequency of individual agents, their anatomical and gender distribution at the Clinic of Surgery, University Clinical Centre Tuzla in 2005.v., Results: Our study showed that gram negative bacteria were more common trigger of IHI (76.37%), and especially the urinary and respiratory tract and surgical wounds infections. We also showed that men from older age groups are more likely to have IHI., Conclusion: Active surveillance and tracing for agents, especially in high-risk groups of patients is the best method of prevention of IHI occurrence.

Urinary tract infections (UTI) cause a great number of morbidity and mortality. These infections are serious complications in pregnancy, patients with diabetes, polycystic kidneys disease, sickle cell anaemia, kidney transplant and in patients with functional or structural anomalies of the urinary tract. The aim of this investigation was to determine a dominant causative agents of UTI and some of the clinical and laboratory characteristics of acute community-acquired UTI in adult hospitalised patients. We studied 200 adult patients with acute community-acquired UTI hospitalised in the Clinic for Infectious Diseases Tuzla from January 2006 to December 2007. The patients were divided into two groups: a group of patients with E. coli UTI (147) and a group of patients with non-E. coli UTI (53). In these two groups, the symptoms and signs of illness, blood test and urine analysis results were analysed. Our results have shown that the patients with E. coli UTI frequently had fever higher than 38,5 degrees C (p<0,0001), chills (p=0,0349), headache (p=0,0499), cloudy urine (p<0,0001), proteinuria (p=0,0011) and positive nitrite-test (p=0,0002). The patients with non-E. coli UTI frequently had fever lower than 38,5 degrees C (p<0,0001) and urine specific gravity <1015 (p=0,0012). There was no significant difference in blood test results between patients with E. coli and non-E. coli UTI. These clinical and laboratory findings can lead us to early etiological diagnosis of these UTI before urine culture detection of causative agents, which takes several days. Early etiological diagnosis of the E. coli and non-E. coli UTI is necessary for an urgent administration of appropriate empirical antibiotic treatment. This is very important in prevention of irreversible kidney damage, prolonged treatment, complications, as well as recidives and chronicity of the illness.

Prevalence of hepatitis C virus (HCV) genotypes in Bosnia and Herzegovina (B&H) is an issue that is not sufficiently researched and there is a need for studies that would explore this in detail.The aim of this study was to determine the distribution of HCV genotypes in the group of patients with chronic hepatitis C and also in the group of first time blood donors that tested positive for anti HCV antibodies during the blood screening process. Our secondary goal was to compare the proportions of HCV genotypes between these two groups.We analyzed 75 blood samples of patients with confirmed chronic hepatitis C. We also analyzed 13/16082 blood samples of first time blood donors found to be HCV positive during the blood screening process. We also determined HCV genotype in HCV RNA positive samples.We have found that genotype 1b was more prevalent in chronic hepatitis C patients (52/75; 69,3%) than in first time blood donors (6/13; 46,1%), however this difference was not statistically significant (c2=1,721; df=1; p=0,19). Genotype 1a was more prevalent in the group of first time blood donors (3/13; 23,1%) than in the group of chronic hepatitis C patients (3/75; 4%), but this was also with limited statistical significance (c2=3,71; df=1; p=0,054). We have not found any significant difference in prevalence of genotypes 1a (p=0,2) and genotypes 3 (p=0,70) when compared between chronic patients (3/75 and 16/75; respectively) and first time blood donors (3/13 and 4/13; respectively). Our study confirmed domination of genotype 1b in the region of northeastern B&H which is in accordance with HCV genotype prevalence in other countries in our part of Europe.

Introduction: Acute infectious diarrhea is a global health problem especially in infants and children, and is a leading cause of morbidity and mortality. The ethiology of acute infectious diarrhea and also biochemical, epidemiological and clinical characteristics of children dying with infectious diarrhea are investigated in this study., Methods: 201 children, aged from 6 months to 14 years, with acute infectious diarrhea admitted to the Infectious Diseases Clinic in Tuzla in the period from 21st December 1999 to 21st December 2000 were included in the study., Results: Enteropathogens were identified in stool samples in 103 (51.3%) of 201 examined children. Viruses were identified in 51 (25.4%) cases, bacteria in 44 (21.9%), fungi in 3 (1.5%), and parasites in 2 (1%). Rotavirus, a frequent pathogen, was detected in 48 cases (23.9%), followed by Salmonella species in 20 (10%), EPEC in 10 (4.9%), and Shigella species in 9 (4.5%) cases. In this study the authors noticed that the highest morbidity was recorded in children in the first 2 years of life (70.5%), and among rural community (68.4%). The detection of rotavirus decreased with increasing age of cases and peaked in winter and autumn. Blood in stool was most common in children with shigellosis (22.2%)., Conclusions: High percentage of infants and children dying with acute infectious diarrhea presents a serious socio-economic and medical problem in Tuzla region of Bosnia and Herzegovina. Rotavirus is the single most common pathogen in children with infectious diarrhea.
