IntroductionThe addiction to heroin is a severe disorder and its treatment represents a complicated, long-lasting process, which includes a series of various interventions which have to be constantly adjusted to patients' present state and his abilities to accept the therapy. The addiction is very resistant to treatment and if the program is not at the same time, enough influential and persistent, but also acceptable to the addict to stick to it for months or even years, the expected results will not be achieved. Retention to the program, abstinence from the illicit drugs, reduction of illegal activities and improving the aspects of socially acceptable behaviour are the best indicators of therapeutic efforts [1-5].Already thirty years ago, the most of western-European countries and USA, Canada and Australia have accepted the use of methadone as a recognized method for treatment of opiate addicts and a useful tool in the frame of 'harm-reduction' approach for helping the not-motivated or incurable heroin addicts. Methadone enables those patients to stop or significantly reduce taking heroin. Although methadone does not create the feeling of euphoria similar to the effect of heroin, it replaces the biological lack of endorphins at the opioid receptors in brain and, with its help, the patient can achieve a psychophysical balance and control the pathological addict's craving. The use of methadone is the best way to attract the addicts from the street to the process of treatment and, if it is well organized and spread, can ultimately direct many addicts towards the programs that would help them in stabilizing the permanent abstinence [1-5].In the evaluation study carried out by the American National Institute for Drugs (NIDA) it has been found that the substitution therapy reduces users' heroin intake for 70%, and their criminal activity by 57 %. [6]. It has also been reported that the countries which use methadone attract up to 75% of opiate addicts to their programs, while those that do not use it, achieve less than 20 %, making the mortality of addicts due to overdose very high. A large number of addicts included in substitution programs function better socially, i.e. better fulfill their duties at the workplace and in families and display significantly less dealings with criminal activities, particularly with selling drugs, thus reducing the risk of initial drug abuse among the healthy population. Application of methadone improves the physical and mental health of the addict, his life gets longer and the risk for early sudden death is reduced. By using methadone, physical and mental health of addicts is improved, their lifespan prolonged i.e. the risk of sudden death is reduced. The addicts in substitution programs are less dangerous concerning the spread of HIV infection, hepatitis and encouraging others to take drugs. The use of methadone in pregnancy is absolutely indicated: it reduces the risk of unwanted pregnancy termination and the risk of damaging the fetus. [1]."Drug free" residential treatment of addictions in the frame of therapeutic communities (TZ) started in early sixties as groups of self and mutual help, as an alternative to the existing conventional programs. The mean duration of stay differs from TZ to TZ (18-60 months). The staff consists mostly of former addicts, while the rest of the staff consists of medical professionals from the field of mental health, psychologists, defectologists, and pedagogues and similar. The aim of staying in TZ is a global change of lifestyle, including abstinence from the illegal substances, elimination of anti-social activities, gathering skills for job-finding and the development of pro-social efforts and values. In TZ, detoxification is the condition to enter the treatment and not the goal of it. Most of the patients who enter TZ already have histories of multiple drug abuse, significantly disturbed psychosocial functioning and consequently, significantly lower quality of life. …

INTRODUCTION Use of intravenous heroin carries a risk of serious medical conditions, including acquiring blood-borne infections. Therefore, hepatitis B virus (HBV) and hepatitis C virus (HCV) infection represent a threat for people who inject drugs (PWID). The objectives of this study were to determine the extent and characteristics of risk factors for acquiring HBV and HCV infection in PWID included in opiate substitution treatment in the southern part of Bosnia and Herzegovina (B&H). METHODOLOGY The study included 120 adult PWID of both sexes who participated in opiate substitution treatment. All participants were interviewed, and their blood samples were tested for the presence of the surface hepatitis B virus antigen (HBsAg) and hepatitis C virus antibodies (anti-HCV). Prevalence data were obtained and compared to the serological status. RESULTS HBsAg prevalence among PWID was 0.8% (1/120), whereas seroprevalence of anti-HCV was 52.5% (63/120). PWID exposed to risk-behavior factors (such as unsafe sexual activity, serving prison sentence, and tattooing) were more frequently anti-HCV positive. Sharing drug paraphernalia was found to be the most significant risk factor. The highest predictive values for acquiring HCV-infection were attributed to PWID who used heroin for more than three years and who were unmarried. CONCLUSIONS HBsAg prevalence among PWID is rare (0.8%), while HCV-infection (52.5%) presents an important health and social issue among PWID in B&H. Sharing drug paraphernalia and intravenous heroin use longer than three years were the most prominent risk-behavior factors among the patients we investigated.

The aim of this study was to clarify the clinical role of CD44 expression in ovarian serous cancer, and its relation to clinicopathologic prognostic factors, disease free survival and overall survival (OS). Immunohistochemical staining for CD44 was performed on 81 formalin-fixed, paraffin-embedded tumor sections. CD44 expression was found in 43% of ovarian carcinoma samples. Correlations between categorical variables were studied using the &khgr;2 and the Mann-Whitney U test. For survival analysis, the Kaplan-Meier method, the log-rank test and the Cox proportional hazard regression model were used. We did not find any statistically significant difference in the distribution of respondents according to clinical stage of the disease, tumor grade or the presence of vascular invasion in relation to the expression of CD44. According to the results of uninominal analysis, early International Federation of Gynecology and Obstetrics (FIGO) stage of the disease (P=0.003) was associated with longer disease free survival, while the expression of CD44 (P<0.001), FIGO stage III and IV (P=0.009) and the finding of vascular invasion (P=0.005) was related to a shorter OS. In conclusion, we proved that positive CD44 immunoexpression is a independent prognostic indicator of shorter OS of patients with ovarian serous cancer.

INTRODUCTION Influenza A H1N1pdm09 virus infection causes an epidemiologically and clinically severe disease mostly characterized by pneumonia, resulting in a high mortality rate. The purpose of this study was to investigate and compare epidemiological and clinical characteristics of influenza A H1N1pdm09 virus infection in patients hospitalized during the pandemic (2009/10) and post-pandemic seasons (2010/11). METHODOLOGY The data of patients with laboratory-confirmed influenza A H1N1pdm09 virus infection hospitalized and treated at the University Hospital for Infectious Diseases Dr. Fran Mihaljevic in Zagreb, Croatia in the first two seasons of appearance were analyzed. RESULTS Compared to the pandemic season, in the post-pandemic season, patients were hospitalized longer, had higher values of inflammatory parameters, and were more often treated with antibiotics. The total number of risk factors in patients did not vary significantly between the two seasons. In the pandemic season, a significantly higher number of obese patients and patients with chronic lung disease was observed, whereas in the post-pandemic season, a statistically significant number of patients presented with symptoms of chronic cardiac and neuromuscular diseases. Primary viral pneumonia was frequently registered in younger adults during the pandemic season, whereas in the post-pandemic season, there were more cases of bacterial pneumonia. CONCLUSIONS During the pandemic season, the influenza A H1N1pdm09 virus infection caused a severe disease with rare bacterial complications, especially in adult patients. The common characteristics of the influenza A H1N1pdm09 virus were lost in the post-pandemic season, assuming the shape and characteristics of the seasonal influenza A virus.

Two cases of human cutaneous anthrax were reported in September 2014 in south-western Bosnia and Herzegovina. The two men were involved in slaughtering a cow and handled its Bacillus anthracis-infected meat. Anthrax has been sporadically observed in livestock in Bosnia and Herzegovina, but no confirmed human cases had been reported in the country in the last two decades. Clinicians in the country should be aware that anthrax may occur in humans, arising from exposure to infected animals.

Lyme borreliosis (LB) is caused by the spirochete Borrelia burgdorferi, which is transmitted to humans by ticks of the Ixodes ricinus complex. It is manifested by a variety of clinical symptoms and affects skin, joints, heart, and nervous system. Neurological manifestations are predictable and usually include meningoencephalitis, facial palsy, or radiculopathy. Recently, a dramatic rise in the number of diagnosed cases of LB has been observed on the global level. Here we show the first case of Lyme neuroborreliosis in southern Bosnia and Herzegovina, which was first presented by erythema chronicum migrans. Unfortunately, it was not recognized or well treated at the primary care medicine. After eight weeks, the patient experienced headache, right facial palsy, and lumbar radiculopathy. After the clinical examination, the neurologist suspected meningoencephalitis and the patient was directed to the Clinic for Infectious Disease of the University Hospital Mostar, where he was admitted. The successful antimicrobial treatment with the 21-day course of ceftriaxone was followed by normalization of neurological status, and then he was discharged from the hospital. This case report represents an alert to all physicians to be aware that LB is present in all parts of Bosnia and Herzegovina, as well as in the neighboring regions.

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.
