HERBALIFE® ASSOCIATED SEVERE HEPATOTOXICITY IN A PREVIOUSLY HEALTHY WOMAN.

Lately there has been an increased consumption of herbal preparations, distributed as nutritional supplements, often claimed to be 'natural' and harmless. However, as their use is not subjected to strict pre-marketing testing and regulations, their ingredients are not clearly defined and there is no quality control or proof of their effectiveness and safety. A growing body of references accentuate their harmful effects, in particular hepatotoxicity, which varies from minimal hepatogram changes to fulminant hepatitis requiring liver transplantation. This case report describes liver damage that was highly suspected to originate from Herbalife® products consumption. We excluded alcohol, viral, metabolic, autoimmune and neoplastic causes of liver lesions, as well as vascular liver disease, but we noticed a connection between the use of Herbalife® products and liver damage. The exact mechanism of liver damage in our patient was not determined. After removing the Herbalife® products, liver damage resolved and there was no need to perform liver biopsy. Taking into consideration the growing consumption of herbal products and their potential harmfulness, we consider that more strict regulations of their production process and sale are necessary, including exact identification of active substances with a list of ingredients, toxicologic testing and obligatory side effect report.

Influence of various factors on functional dyspepsia.

Aim of the research is to establish the prevalence of dyspepsia in Osjecko-baranjska County, to establish its specific characteristics and to determine the effect of demographic, anthropometric, and socioeconomic factors. It is a cross-sectional and case control study conducted in 2010 on systematic sample of 900 subjects between 20 and 69 years of age. Every subject was sent an invitation letter and a Rome III diagnostic questionnaire for one of the disorders. A scoring algorithm was used to confirm or exclude the diagnosis of functional dyspepsia (FD). The chi-square test, t-test and logistic regression were used for analysis.Prevalence of dyspepsia was recorded in 16, 56%, of subjects. There is no statistically significant difference in prevalence of dyspepsia male and female. The prevalence of dyspepsia increases with age. Correlation with the place of birth was proven. There is no correlation between the current place of residence (rural area and town) and dyspepsia. There is a correlation with marital status. Correlation between stool forms was proven. There were a greater number of subjects that had at least one alarm symptom or some of the psychosocial factors and they often suffered from a chronic disease. The risk for dyspepsia increases with age, body mass index (BMI), and poorer health. Logistic regression showed the following as statistically significant for dyspepsia: place of birth and self-assessment of one's health. FD presents a significant health problem. Rome III survey questionnaire proved to be an acceptable method for diagnosing this functional disorder in clinical-consilliary and primary health care for persons showing signs of alarm and needing further diagnostic treatment.

Demographic, anthropometric and socioeconomic characteristics of functional constipation in Eastern Croatia.

Aim of the research is to establish the prevalence of constipation in Osjecko-baranjska County, to establish its specific characteristics and to determine the effect of demographic, anthropometric and socioeconomic factors. It is a cross-sectional study conducted in 2010. on systematic sample of 900 subjects between 20 and 69 years of age. Every subject was sent an invitation letter and a Rome III diagnostic questionnaire for one of the disorders. A scoring algorithm was used to confirm or exclude the diagnosis of functional constipation. The chi-square test (chi2 test), t-test and logistic regression were used for analysis. The prevalence of constipation in our study was 22.19%, which is higher than the prevalence in most other countries, where it ranges from 5% to 18%. In our study statistically significant variables were: place of current residence (urban), education level (high school), marital status (divorced people), a larger number of household members and a lower health status by self-assessment. According to t-test persons with constipation on average are older, have higher average BMI and lower average grade valued financial status of households and their health. There were a greater number of subjects that had at least one alarm symptom or some of the psychosocial factors and they often suffered from a chronic disease. Functional constipation presents a significant health problem. Rome III survey questionnaire proved to be an acceptable method for diagnosing this functional disorder in clinical-consilliary and primary health care, and for persons showing signs of alarm and needing further diagnostic treatment.

Irritable bowel syndrome in Croatia.

There are three epidemiological studies of irritable bowel syndrome (IBS) that were conducted in Croatia (in the area of Zagreb in 2002, Bjelovarsko-bilogorska County in 2008, and finally in Osjecko-baranjska County in 2011). The aim of this study is to analyze the anthropometric, demographic and socioeconomic characteristics of IBS in Croatia comparing these three studies. The studies included a questionnaire based on Rome criteria. Study population matched the adult population of Croatia according last available census (1991, 2001 resp.). Studies showed a high prevalence of IBS and some common factors relevant for development of IBS were determined such as gender, body mass index and lower level of education. There is a need for further investigations in coastal Croatia applying a uniform questionnaire on anthropometric, demographic and socioeconomic characteristics of IBS and Rome III criteria, diagnostic questionnaires and scoring algorithm for functional gastrointestinal disorders developed by Rome Foundation applicable in clinical practice and population studies, regarding the significant high prevalence of IBS in our country.

Assessment of nutritional status in cancer patients in Osijek health area center.

The aim of this research was to perform the nutritional screening and clinical assessment of malnutrition and of cachexia as well as the need for enteral nutritional support. We used an international questionnaire for nutrition screening and clinical assessment of malnutrition. 103 cancer patients participated in the research. The results indicate that 80patients (78%) have recently unintentionally lost weight in the last six months. Of those 80 patients 12 (15%) have lost more than 15 kilograms. Three patients (3%) suffer from hunger because of their inability to eat. Presence of multiple (3 or more) symptoms (nausea, vomiting, diarrhea or anorexia) was reported by 11 patients (11%). Severe work dysfunction was found in 28 patients (27%). 14 patients (14%) experience significant loss of musculature (musculus quadriceps femoris, musculus deltoideus). The obtained results indicate that 15patients (14%) are severely, and 39 patients (38%) are moderately undernourished. This survey confirmed the significance of nutritional screening in cancer patients, as it detected 30 patients (29%) who required introduction of enteral nutrition.

Anthropological, demographic and socioeconomic characteristics of irritable bowel syndrome.

Irritable bowel syndrome (IBS) in one of the most frequent functional gastrointestinal disorders (FGIDs) with a prevalence in 10 to 20%, of cases in some developed countries. The Rome Foundation has drawn up Rome III criteria, diagnostic questionnaires and scoring algorithm for FGIDs, applicable in clinical practice and population studies. The aim of this research is to determine the presence of IBS in Osjecko-baranjska County and the effect of anthropometric, demographic and socioeconomic factors. 703 subjects selected in the systematic sample filled in the Rome III diagnostic questionnaire for IBS. Prevalence of IBS was recorded in 29.16%, in men in 21.39%, and in women in 36.69% of cases, anxiety and depression in 26.34% and 25.85%. Persons suffering from IBS were on average shorter, weighed less and had a lower BMI than persons not showing signs of IBS. Women have 2.101 times greater chance of risk of IBS, and with an increase in the number of members in the household the risk of IBS increases 1.139 times. Rome III survey questionnaire is an acceptable method for diagnosing IBS and identifying persons showing signs of structural changes in order to provide further treatment.

Clinical and anorectal motility features in chronically constipated children.

Constipation is a common problem in children. It can be a symptom of functional disorder in majority of cases, but sometimes a serious organic disease is a cause of constipation. Anorectal manometry plays an important role in the diagnostic procedure. It can be presumed that some values of manometric parameters could be very useful in treatment plan. The aim of this study was to confirm or exclude such limits in manometric finding, to make a plan of the therapy more accurate. Therefore the group of 81 constipated children was investigated. There were 58 patients suffering from functional constipation and 23 with organic disorders. The age of the patients was 3 to 15 years. Scoring system was applied to estimate severity of constipation and anorectal manometry was performed. Our results did not show significant correlation between clinical symptoms and signs and the values that we obtained using anorectal manometry. But, we recommend anorectal manometry because it is a safe method and contributes to clarify the diagnosis, which is very important for treatment plan.

Screening with mammography organized by family physicians teams: what have we learnt?

The mammography, recommended as standard method for screening on breast cancer, can reveal suspicious lesions early enough to anable cancer elimination in entirely. Experience with women of the target population, 50-69 years old, included in the mass screening programs, show the reduction in the specific mortality by 30%. One of the main problem in organizing the preventive programs is how to increase responsiveness of subjects to screening. In the study, based on the large sample of over 1000 of subjects and 20 family medicine practices, included in the investigation, we showed that it is possible, by a pro-active involvement of family physicians teams and intensive educational and motivational activities, to achieve high level of over 80% of responsiveness to mammography screening. Analysis of the reasons of nonresponsiveness can contribute to better understanding of the mental processes included in a self-decision making. This, as the final aim, can help family physicians in their efforts to overcome many hidden barriers which obstruct their patients to accept the mammography screening.

Efforts in fighting against cancer in Croatia have to be focused on the primary health care.

This manuscript is a comprehensive review of the long-lasting tradition and the state-of-the-art in the prevention and early detection of cancer in Croatia. Compared with other European countries, Croatia holds a high and unfavourable position in cancer morbidity and mortality. Global experience in implementation of national programmes for the early detection of cancer clearly shows that such approach is the most successful and in the long-term the least expensive method for fighting against cancer. In Croatia, numerous separate actions in cancer care have been taken, but never systematically, nor included in a health care policy. The National Programme for the Prevention and Early Detection of Cancer of the common localizations for which effective screening tests are available (breast, uterine cervix, colon and prostate) has recently been launched. Local long-standing experience of the Osijek-Baranja County in implementation of programmes of cancer care contributed significantly to these initiatives. In this review, draft National Programme and the early results of its implementation were presented. In addition, preparations for the research project "Model of early cancer detection integrated in a practice of family physician", recently set up by the Department of Family Medicine of the School of Medicine, University of Osijek, were described. In this project, the programme of the early detection of cancer in which family physicians take responsibility for the programme implementation is suggested. Possible advantages of this model, compared with the model proposed by the National Programme, centrally directed and mostly supplied by the public services, are pointed out.

Effect of surgical training course on performance of minor surgical procedures in family medicine physicians' offices: an observational study.

AIM: To examine the influence of a practical surgical course on the number of minor surgical procedures performed by family physicians. METHODS: We compared the number of minor surgical procedures performed by family physicians in 59 offices in the city of Osijek and surrounding rural area during 12 months before and after the 40-hour practical surgical course held in September 2006 by surgeons and family medicine specialists. Minor surgical procedures taught in the course included management of ingrown toenails, abscesses/comedones, and minor wounds, anesthesia application, disinfection, use and sterilization of surgical instruments, and antibiotic treatment. RESULTS: The number of minor surgical procedures performed in family medicine offices almost doubled (503 vs 906 after the course, P<0.001, Wilcoxon test). The median number of abscesses/comedones treatments per physician increased from 1 to 6 (P<0.001, Wilcoxon test), the number of managed wounds increased from 111 to 217 (P<0.001, Wilcoxon test). The increase in ingrown toenail resections was also significant (from 120 to 186, P=0.004, Wilcoxon test). Fifty percent of physicians did not treat patients surgically, irrespective of the training. We found no association between the number of performed procedures and age, length of employment, or location of the physician's office (urban vs rural). However, we found that male physicians performed more surgical treatments both before and after the course (abscesses/comedones: P<0.001 and P=0.108 respectively; ingrown toenail resections: P=0.008 and P=0.008 respectively; minor wounds: P=0.030 and P<0.001; respectively). CONCLUSION: Practical courses can encourage practitioners to treat the patients surgically in their offices and, thus, increase the number of services offered in primary care. Female physicians should be more encouraged to perform minor surgical procedures in their offices.

Psycho-social aspects of measures aimed at decreasing prevalence of chronic diseases in the population of returnees in the Osijek Region, Croatia.

Recognizing high prevalence of Diabetes mellitus and cardiovascular disorders and low coverage by preventive examinations in the population of returnees, in Osijek Region, we initiated activities for early detection and better managing of chronic diseases. Measures done, were based on public health working methods, such as: education, solidarity and self-responsibility. A special attention was put on psychosocial aspects of the health-related matters. Exactly, free glucose tests were organized with subsequent healthy lifestyles advice session. It was brought to our attention that such intervention should be as much as possible individually oriented, considering many personal and social characteristics of an individual. Gynecological examinations for all women interested in were also organized. On that occasion, women were interviewed in order to get information about their motivation and obstacles for doing preventive examinations and difficulties in adaptation as well. Finally, outcomes of the Project were summarized and put in a larger social context.

Case-control study of risk factors for lumbar intervertebral disc herniation in Croatian island populations.

AIM: To investigate the risk factors for lumbar intervertebral disc herniation (L4/L5 or L5/S1) severe enough to require surgery of the lower spine among 9 isolated populations of Croatian islands and to evaluate predictive value, sensitivity, and specificity of a simple screening test based on the understanding of the risk factors in this population. METHODS: In a sample of 1001 examinees from Croatian island populations, we identified all subjects who underwent surgery of the lower spine due to lumbar intervertebral disc herniation L4/L5 or L5/S1 and selected 4 controls matched by age, gender, and village of residence for each of them. Odds ratio was computed for the following variables: body mass index, occupation, intensity of physical labor at work, intensity of physical labor at home, smoking index, claudication index, self-assessed limitation in physical activity, level of education, socio-economic status, and family history of lumbar intervertebral disc herniation requiring surgery. RESULTS: Comparison of 67 identified cases with 268 controls revealed the highest odds ratios (OR) for positive family history (OR 4.00; 95% confidence intervals [CI], 1.89-6.11, P<0.001), intensity of physical labor at work defined as (hard) (OR 2.94; 95% CI, 1.07-4.81, P<0.001), and body mass index of 25.7 or more (OR 2.77, 95% CI, 1.05-4.49, P=0.002). A simple screening test based on the presence of any two of these three criteria has 74% sensitivity and 82% specificity to detect persons who underwent lower spine surgery due to lumbar intervertebral disc herniation in the population aged 40 years or more. CONCLUSION: Occurrence of lumbar disk herniation severe enough to require surgery of the lower spine can be predicted using a very simple set of criteria. This type of screening could reduce the need for surgery in isolated communities through prevention within primary health care.

Demonstrating reduced environmental and genetic diversity in human isolates by analysis of blood lipid levels.

AIM: To test the hypothesis that phenotypic diversity in isolated human populations is decreased in comparison with general outbred population because of reduced genetic and environmental diversity. To demonstrate this in populations for which reduced genetic and environmental diversity had already been established, by studying the amount of variation in plasma lipid levels. METHODS: Fasting plasma lipid levels (cholesterol, triglycerides, low density lipoprotein [LDL], and high density lipoprotein [HDL]) were measured in randomly selected 300 inhabitants from 2 isolated human populations, the island of Rab and the neighboring islands of Vis and Lastovo, Croatia. The populations were chosen based on previous analyses of genetic diversity and lifestyle patterns, which were shown to be both less diverse and more uniform than the general Croatian population. We studied whether the 25'-75' and 5'-95' interpercentile ranges in observed values were consistently smaller in 2 samples of 300 examinees from isolated populations in comparison with nearly 6000 examinees from an earlier study who were demographically targeted to represent the larger Croatian population. RESULTS: General population had much wider range of observed values of triglycerides and HDL than both isolated populations. However, both isolated populations exhibited greater extent of variation in the levels of LDL, while the ranges of cholesterol values were similar. CONCLUSION: Although reduced genetic and environmental diversity in isolated human populations should necessarily reduce the variance in observed phenotypic values, it appears that specific population genetic processes in isolated populations could be acting to maintain the variation. Departure from the Hardy-Weinberg equilibrium due to consanguinity, sub-structuring and differentiation within the isolates, and increased rate of new mutations could theoretically explain this paradox.

Present state and possibilities for improvement of cancer prevention and early detection in the Osijek-Baranya county.

Cancer morbidity and mortality are on a steady increase in Croatia. Technologic possibilities for appropriate management are available for four cancer sites, i.e. cancer of the breast, cervix uteri, colorectum and prostate, and include cancer prevention and early detection in individuals yet free from manifest signs of the disease. The magnitude of the problem, the experience acquired to date, health care personnel available, and additional resources required to launch a systematic program of early detection of the disease are presented. The program should be initially launched in a county with greatest experience in early detection of cancer, where health care service is ready to immediately start its implementation. The role of family physician, gynecologic service at primary health care level, and polyclinic-consultation hospital service in program implementation is described. The following three possible options for early detection of cancer are analyzed and proposed: minimal program (early detection every 3 years), medium program (the same individuals examined every 2 years), and optimal program proposed by the American Cancer Society and other national and international organizations.
