CORRELATION BETWEEN THE LEVEL OF COLORECTAL ANASTOMOSIS AND ANORECTAL FUNCTION.

Anterior rectal resection is a standard surgical procedure for treating carcinomas of rectum and distal sigmoid colon. In many cases of anterior rectal resection, postoperatively some level of fecal incontinence may occur. The aim of our study was to evaluate the impact of the colorectal anastomosis level on anorectal functional disorder. In our prospective study, the participants were patients diagnosed with carcinoma of rectum or distal sigmoid colon. All patients underwent standard open or laparoscopic anterior rectal resection. Six months after the surgery, the function of anorectum was evaluated in all participants. Finally, 38 patients were analyzed, including 13/38 (34.2%) patients with high rectal anastomosis, 11/38 (28.9%) with mid rectal anastomosis and 14/38 (36.8%) with low rectal anastomosis. Patients with a lower level of anastomosis had a statistically significantly greater number of stools, higher urgency and discrimination impairment, more pronounced solid, liquid and gas incontinence, and greater need for diapers (p<0.05 all). Therefore, patients with lower anastomosis had a statistically significant impairment of their quality of life and higher Wexner score (p<0.001 for both analyses). Our study results suggested reduced neorectal capacity to be the main pathophysiological factor for the development of postoperative anorectal function impairment.

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.

How to treat an extensive form of primary intestinal lymphangiectasia?

We report a case of a 42-year-old man with a rare disorder known as primary intestinal lymphangiectasia, which is characterized by dilated intestinal lymphatics that lead to the development of protein-losing enteropathy. The patient presented with a grand mal seizure caused by malabsorption-derived electrolytes and a protein disorder. Signs of the disease, including chronic diarrhea and peripheral edema, manifested 10 years ago, but a diagnosis was never made. The diagnosis was suspected because of the clinical manifestations, laboratory tests, imaging and endoscopic findings. Hyperemic and edematous mucosa of the small intestine corresponded to scattered white spots with dilated intestinal lymphatics and whitish villi in the histological specimen of the biopsied jejunal mucosa. Although numerous therapeutic strategies are available, only octreotide therapy proved to be an effective means of therapeutic resolution in this patient. Although the patient had a partial remission following the use of a slow release formula of octreotide, his prognosis, clinical course, and future treatment challenges are yet to be determined.

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.

Do gender and age influence the frequency of Helicobacter pylori infection?

BACKGROUND: (13)C urea breath test (UBT) is a noninvasive method for detection of Helicobacter pylori (H. pylori) infection. The aim of this study was to determine age and gender differences in patients with positive UBT. PATIENTS AND METHODS: During the period 2008-2011, a total of 3,000 patients, who did not receive Hp eradication therapy before our study, underwent UBT in Laboratory of Clinical Hospital Sveti Duh. Data were analyzed according to age and gender. RESULTS: A total of 1,400 patients were positive (47 %), 670 males and 730 females (the male/female ratio for positive UBT was 0.92). The male predominance was found in people born between 1930 and 1939, 1940 and 1949, and 1960 and 1969, respectively. The majority infected are born between from 1940 and 1979, with the highest point from 1950-1969. CONCLUSIONS: Our study results confirm the importance of epidemiologic characteristics of Hp infection in our region.

Celiac disease and fulminant T lymphoma detected too late in a 35-year-old female patient: case report.

UNLABELLED: Celiac disease is the most common chronic gastroenterological autoimmune disease characterized by gluten intolerance. The diagnosis of celiac disease and enteropathy-associated T cell lymphoma is often made when it is too late.Case report describes a 35-year-old female patient managed for one year under the diagnosis of inflammatory bowel disease and admitted to our hospital for exacerbation of the underlying disease. However, inflammatory bowel disease was ruled out by diagnostic work-up, while the clinical picture and the findings obtained raised suspicion of lymphoma. The patient's condition was additionally complicated by fulminant course of the disease and ileus. CONCLUSION: Early diagnosis and appropriate treatment of the disease, and follow up of family members are crucial to prevent intestinal lymphoma development.

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.

Analysis of the influence of various factors on anemia in patients with lymphoid malignancies.

Anemia is a frequent complication of lymphoid neoplasms as a result of the disease and myelotoxic chemotherapy, and has a significant impact on treatment outcome, survival and quality of life. The aim of this study was to investigate clinical characteristics of anemia in lymphoid malignancies and to assess the need of anemia treatment in the context of modern therapeutic possibilities. Fifty-five patients (32 female and 23 male) with non-Hodgkin's lymphoma (NHL, n = 30), chronic lymphocytic leukemia (CLL, n = 8) and multiple myeloma (MM, n = 17) were included in the study. The influence of age, sex, type of malignancy and chemotherapy on the prevalence, severity and type of anemia before and after chemotherapy was analyzed. The prevalence of anemia was 51.02% before (A1) and 55.31% after (A2) chemotherapy. Women had a higher prevalence of anemia than men (63% vs. 43%), but the severity was higher in men at the beginning (103 vs. 99 g/L Hb) and at the end of treatment (101 vs. 89 g/L Hb). The highest prevalence of anemia was found in MM (69%), followed by NHL (44.4%) and CLL (40%) before chemotherapy, and in MM (68.7%), CLL (42.9%) and NHL (20.8%) after chemotherapy. The prevailing anemia was anemia of chronic disease (53.8%), followed by anemia due to multiple causes (anemia of chronic disease + iron deficiency anemia or anemia of chronic disease + hemolytic anemia; 30.7%), anemia due to iron deficiency (11.5%) and hemolytic anemia (7.6%). The prevalence of anemia as a consequence of the disease is high in lymphoproliferative disease, but there was no significant rise under chemotherapy, even showing a decline in NHL patients (44% vs. 21%), however, the severity of anemia increased. Since stage 1 anemia according to the WHO prevailed, only a small number of patients required transfusion therapy. About 27% of all patients had hemoglobin values <100 g/L during chemotherapy and could be candidates for erythropoiesis-stimulating agent treatment.

Impaired esophageal function in patients with irritable bowel syndrome.

The aim of the study was to determine prevalence of the signs and symptoms related to esophageal dysfunction in irritable bowel syndrome (IBS) patients, and to investigate sensorimotor function impairment based on the esophageal manometry study, thus to determine the correlation between them. The study included 30 patients with IBS, 14 of them with diarrhea (IBSd) and 16 with constipation (IBSc) as a predominant discomfort. Control group consisted of 30 healthy subjects. The patients were included in the study on the basis of the Rome criteria for IBS. In addition to thorough history and physical examination patient underwent esophagogastroduodenoscopy and esophageal manometry. The values of esophageal manometry obtained in healthy subjects served as controls in manometry studies. The patients with IBS suffered a great number of both colonic and extracolonic signs and symptoms, however, there was no statistically significant difference in the prevalence of particular symptoms between the two patient subgroups. In comparison with healthy subjects, the patients suffering from IBS showed pathologically altered values in the majority of parameters of esophageal motility. Comparison of the two subgroups of IBS patients according to esophageal motility characteristics yielded differences in only few of them. The results obtained in the study could explain why the patients with IBS quite commonly complain of the symptoms related to upper gastrointestinal tract, such as heartburn and chest pain of noncardiac genesis. The results also suggest that the IBS might be associated with considerably more extensive smooth muscle or innervation changes than presumed before.

Lower gastrointestinal disorders in patients with irritable bowel syndrome.

Irritable bowel syndrome (IBS) is a functional disorder of the gastrointestinal system characterized by abdominal pain related to bowel emptying, defecation impairment and abdominal distention. The aim of the study was to objectify lower gastrointestinal system disturbances in IBS patients. Thirty IBS patients and 30 healthy subjects were included in the study. IBS patients were divided into two subgroups: IBS with predominant diarrhea (IBSd) and IBS with predominant constipation (IBSc). All study subjects underwent physical examination (including digitorectal examination), standard laboratory testing and anorectal manometry. Endoscopy was performed only in group of IBS patients. A statistically significant difference was recorded in most manometric parameters between healthy subjects and IBS patients, which was even more pronounced in IBSd patients. Study results showed that the intestinal motility disorder underlying IBS could be objectified by use of anorectal manometry.

Clinical course of uremic neuropathy in long-term hemodialysis.

One hundred and thirty-one patients on long-term hemodialysis were examined for the presence of clinical symptoms and signs, and for the effects of dialytic age, age and sex on uremic neuropathy. According to dialysis age, the patients were divided into three subgroups: low dialysis age, < 5 years of dialysis (n = 58); intermediate dialysis age, 5-10 years of hemodialysis (n = 39); and high dialysis age, > 10 years of dialysis (n = 34). Two patient subgroups were differentiated according to mean age of 53.2 years: younger (n = 57) and older (n = 74). Clinical grading of uremic neuropathy was based on Nielsen's criteria. The most common symptoms were restless legs syndrome (47%) and cramps (51%). Sensory symptoms were less common in patients on long-term hemodialysis, most common of them being paresthesia (29%) and burning feet syndrome (28%). Abnormal Achilles reflex (53%) and impaired vibration sense (59%) were the most common clinical signs. Clinically manifested uremic neuropathy was present in more than 80% of all study patients, i.e. mild in 41%, and moderate to severe forms of uremic neuropathy according to Nielsen's criteria in 39%. There was no evident effect of dialytic age and sex on the clinical course of uremic neuropathy, however, there was a clear impact of age. It is concluded that long-term hemodialysis does not influence the clinical course of uremic neuropathy unlike evident deterioration of electroneurophysiologic findings.

Seroprevalence of Helicobacter pylori infection in dyspeptic patients.

The objective of the study was to assess the effect of age on the seroprevalence of Helicobacter (H.) pylori infection in dyspeptic patients. The results obtained in the patient group were compared with findings on the seroprevalence of H. pylori infection in 2051 blood donors. Serum samples were tested by the commercial ELISA and CFT assays according to manufacturer's instructions. The mean seroprevalence of H. pylori infection as determined by ELISA/CFT was 64.0%/51.7% in the group of blood donors and 92.3%/89.5% in the group of dyspeptic patients. Study results indicated a higher prevalence of H. pylori infection in dyspeptic patients as compared with blood donors in all age groups. In the patient S group, H. pylori seroprevalence was not age dependent.

Gastric myoelectrical activity in a population of healthy Croatian subjects.

Myoelectrical activity of the stomach was estimated in healthy Croatian subjects using the latest multi-channel percutaneous electrogastrograph. The aim of the study was to determine normal values of gastric myoelectrical activity for the population of Croatia. The study included 120 healthy subjects of both sexes, various age groups, body mass index values, and mode of lead placement. The measurement was performed 60 min before and 60 min after test meal. The following parameters of gastric myoelectrical activity were analyzed: dominant frequency (DF, c/min); dominant frequency within normal range (DFNR, %); coefficient of variation for dominant frequency (CVDF); dominant strength (DS, mV); postprandial increase intensity in dominant strength (PPIIDS; %); bradygastria (c/min, %); tachygastria (c/min, %); and arrhythmia. DF for the study group as a whole was around 3 cpm, at the normal range midpoint, and all other parameters were within the normal limits. On postprandial measurement, the rate of arrhythmias showed a significant decline. Age was found to influence DF, CVDF and arrhythmia in preprandial but not in postprandial period, whereas sex influenced DF, DS and bradygastria in preprandial period, and DF, CVDF, PPIIDS and tachygastria in postprandial period. The mode of lead placement had no impact on the electrogastrographic parameters observed. The values of gastric myoelectrical activity recorded in healthy Croatian subjects were within the normal range of the values defined by previous studies across Europe.

The impact of age, sex, body mass index and menstrual cycle phase on gastric myoelectrical activity characteristics in a healthy Croatian population.

The aim of the study was to determine the impact of demographic and anthropometric parameters on the gastric myoelectrical activity characteristics in a healthy Croatian population. The influence of age, sex, body mass index (BMI) and menstrual cycle phase on the gastric myoelectrical activity characteristics was assessed. The study included 120 healthy subjects of both sexes (60 male and 60 female), divided into four age groups (18-35, 36-50, 51-65 and > 65 years) and three BMI groups (BMI < 25, 25-30 and > 30). Female subjects of reproductive age were divided into three groups according to menstrual cycle phase (day 1-3, day 4-8 and day 9-20 of menstruation). All study subjects underwent percutaneous electrogastrography (EGG) for 60 min before and 60 min after a test meal. The following parameters of the gastric myoelectrical activity were observed: dominant frequency (DF); dominant frequency within normal range (DFNR, %); coefficient of variation for dominant frequency (CVDF); dominant strength (DS. mV); postprandial increase intensity in dominant strength (PPIIDS, %); bradygastria (BG, c/min, %); tachygastria (TG, c/min, %); and arrhythmia (AR). Age was found to influence preprandial but not postprandial DFNR, CVDF and AR. Sex influenced preprandial DF, CVDF, DS and BG, and postprandial DF, CVDF, PPIIDS and TG. BMI exerted an impact on preprandial TG and AR, and postprandial DF, CVDF and AR. The phase of menstrual cycle influenced DF in preprandial period and none of EGG parameters in postprandial period.

Esomeprazole versus pantoprazole for healing erosive oesophagitis.

The aim of this study was to compare the efficacy of esomeprazole and pantoprazole with regard to healing and relief from gastroesophageal reflux disease-related symptoms. I this multicentre, randomized, single-blind study 180 patients (ITT population) diagnosed with endoscopically proven GERD grade A,B,C received esomeprazole (40 mg once daily (o.d.), n = 90) orpantoprazole (40 mg o.d., n = 90). Healing and relief from GERD-related symptoms were assessed at first and final visit (after 4 or 8 weeks of treatment). Esomeprazole 40 mg provided significantly greater healing than pantoprazole 40 mg after 4 weeks of treatment in patients with EE (77.8% vs. 72.2%). Esomeprazole-treated patients were healed after up to 8 weeks of treatment similar those treated with pantoprazole (92.2% vs. 91.1%). The proportion of heartburn-free days was similar in patients treated with esomeprazole and to those treated with pantoprazole.

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.

The efficacy of cisapride vs. placebo and diet in patients with chronic constipation.

The effects of cisapride (10 mg three times daily) on the stool evacuation characteristics, laxative consumption (symptom diary) and motility pattern (rectoanal manometry) were assessed in patients with chronic idiopathic constipation who fulfilled Rome II criteria. After a 14-day basal period on a diet rich in fiber (phase I), patients were treated with placebo (n = 20) or cisapride (n = 19) (phase II). Anorectal manometry was performed at the end of each phase. The study was controlled, randomized and double blind. Side effects related to the use of cisapride were noted and found to be mild. Cisapride and placebo increased stool frequency from 4 (1-11) to 7 (14-12) (p < 0.001) and from 4 (2-10) to 6 (2-11) (p < 0.05) per week, respectively. Straining was decreased from 69.0% to 39.7% in the cisapride (p < 0.0001) group, and from 79% to 35% (p < 0.0001) in the placebo group. Both cisapride and placebo decreased the feeling of incomplete evacuation from 91.7% to 37.5% (p < 0.0001) and from 82.7% to 39.2% (p < 0.0001), respectively. Cisapride reduced the need of laxatives and showed a tendency to normalize stool consistency but did not influence any other symptom or bowel motility parameter.
