This paper analyzes the development and the current state of axiology in Slovak museums in its historical and legislative context. Additionally, we attempt to define the values that are – or should be – applied to the valuation of objects in museum collections, as well as said valuation’s philosophical, economic and museological underpinnings. The final section of the paper then proposes a pricing tool specifically designed for the evaluation of pricing offers and purchase prices of museum objects during the creation of museum collections.

Background/Aims: Sedation rates may vary among countries, depending on patients’ and endoscopists’ preferences. The aim of this survey was to investigate the rate of using premedication for routine diagnostic upper gastrointestinal (UGI) endoscopy in endoscopy societies, members of the European Society of Gastrointestinal Endoscopy (ESGE). Methods: We evaluated a multiple-choice questionnaire which was e-mailed to representatives of national endoscopy societies, which are members of the ESGE. The questionnaire had 14 items referring to endoscopy practices in each country and the representatives’ endoscopy units. Results: The response rate was 76% (34/45). In 47% of the countries, less than 25% of patients undergo routine diagnostic UGI endoscopy with conscious sedation. In 62% of the responders’ endoscopy units, patients are not asked their preference for sedation and do not sign a consent form (59%). Common sedatives in use are midazolam (82%), diazepam (38%) or propofol (47%). Monitoring equipment is not available ‘in most of the endoscopy units’ in 46% (13/28) of the countries. Though they were available in 91% of the national representatives’ endoscopy units, they are rarely (21%) used to monitor unsedated routine diagnostic UGI endoscopy. Conclusions: In about 50% of ESGE-related countries, less than 25% of patients are sedated for routine diagnostic UGI endoscopy. Major issues to improve include availability of monitoring equipment and the use of a consent form. Copyright © 2006 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Introduction: We have previously shown that a tag single nucleotide polymorphism (rs10235235), which maps to the CYP3A locus (7q22.1), was associated with a reduction in premenopausal urinary estrone glucuronide levels and a modest reduction in risk of breast cancer in women age ≤50 years. Methods: We further investigated the association of rs10235235 with breast cancer risk in a large case control study of 47,346 cases and 47,570 controls from 52 studies participating in the Breast Cancer Association Consortium. Genotyping of rs10235235 was conducted using a custom Illumina Infinium array. Stratified analyses were conducted to determine whether this association was modified by age at diagnosis, ethnicity, age at menarche or tumor characteristics. Results: We confirmed the association of rs10235235 with breast cancer risk for women of European ancestry but found no evidence that this association differed with age at diagnosis. Heterozygote and homozygote odds ratios (ORs) were OR = 0.98 (95% CI 0.94, 1.01; P = 0.2) and OR = 0.80 (95% CI 0.69, 0.93; P = 0.004), respectively (Ptrend = 0.02). There was no evidence of effect modification by tumor characteristics. rs10235235 was, however, associated with age at menarche in controls (Ptrend = 0.005) but not cases (Ptrend = 0.97). Consequently the association between rs10235235 and breast cancer risk differed according to age at menarche (Phet = 0.02); the rare allele of rs10235235 was associated with a reduction in breast cancer risk for women who had their menarche age ≥15 years (ORhet = 0.84, 95% CI 0.75, 0.94; ORhom = 0.81, 95% CI 0.51, 1.30; Ptrend = 0.002) but not for those who had their menarche age ≤11 years (ORhet = 1.06, 95% CI 0.95, 1.19, ORhom = 1.07, 95% CI 0.67, 1.72; Ptrend = 0.29). Conclusions: To our knowledge rs10235235 is the first single nucleotide polymorphism to be associated with both breast cancer risk and age at menarche consistent with the well-documented association between later age at menarche and a reduction in breast cancer risk. These associations are likely mediated via an effect on circulating hormone levels.

Background: Somatic mutations in phosphoinositide-3-kinase catalytic subunit alpha (PIK3CA) are frequent in breast tumours and have been associated with oestrogen receptor (ER) expression, human epidermal growth factor receptor-2 overexpression, lymph node metastasis and poor survival. The goal of this study was to evaluate the association between inherited variation in this oncogene and risk of breast cancer. Methods: A single-nucleotide polymorphism from the PIK3CA locus that was associated with breast cancer in a study of Caucasian breast cancer cases and controls from the Mayo Clinic (MCBCS) was genotyped in 5436 cases and 5280 controls from the Cancer Genetic Markers of Susceptibility (CGEMS) study and in 30 949 cases and 29 788 controls from the Breast Cancer Association Consortium (BCAC). Results: Rs1607237 was significantly associated with a decreased risk of breast cancer in MCBCS, CGEMS and all studies of white Europeans combined (odds ratio (OR)=0.97, 95% confidence interval (CI) 0.95–0.99, P=4.6 × \(10^{−3}\)), but did not reach significance in the BCAC replication study alone (OR=0.98, 95% CI 0.96–1.01, P=0.139). Conclusion: Common germline variation in PIK3CA does not have a strong influence on the risk of breast cancer.

Differential diagnosis between autoimmune pancreatitis (AIP) and pancreatic cancer can be very difficult. The main clinical symptoms in patients with autoimmune pancreatitis are jaundice, weight loss, abdominal pain and new onset of diabetes mellitus. Unfortunately, the same symptoms could be observed in patients with pancreatic carcinoma too. Imaging methods as computed tomography (CT) scan, magnetic resonance imaging (MRI) and endosonography (EUS); together with serological examination (IgG4 and Ca 19-9) play the important role in differentiation autoimmune pancreatitis from pancreatic cancer. Extrapancreatic findings are distinctive in patients with autoimmune pancreatitis. In some cases the pancreatic biopsy is indicated, mainly in patients with focal or multifocal form of autoimmune pancreatitis. Response to steroids (decreased pancreatic or extrapancreatic lesion or damage) is distinctive to AIP. In clinical practice, CT scan seems to be the most reasonable tool for examining the patients with obstructive jaundice with or without present pancreatic mass. Stratification the patients with possible AIP versus pancreatic cancer is important. In patients with AIP it may avoid pancreatic resection, as well as incorrect steroid treatment in patients with pancreatic carcinoma.

The incidence of chronic pancreatitis grows slowly but steadily. At present, alcohol is the most frequent risk factor, although the new forms of so called non-alcoholic chronic pancreatitis, such as genetically induced pancreatitis and its autoimmune variety, are carefully watched. Alcohol consumption continues to be most closely associated with the disease, though it is no more than a risk factor and other aspects, e.g., genetic predisposition, are prerequisite to the disease development. Imaging methods play a fundamental role in diagnosing the disease; non-invasive magnetic resonance and CT, invasive but safe endosonography, and diagnostically rarely used ECRP that, because of its invasive nature, is currently predominantly used for therapeutic purposes. Genetic markers are also exploited, including CFTR mutation, SPINK 1 and PRRS 1 gene, immunoglobulin G4 in the autoimmune form of the disease as well as, alternatively, pancreatic biopsy. Disease symptoms, i.e., pancreatic malabsorption (enzymes with high lipase content) and pancreatic pain are treated conservatively, with paracetamol as the first line therapy for pain followed, if necessary, by so called synaptic analgesics. Alternatively, endoscopic techniques (drainage) or surgery (drainage and resection) are applied. Hereditary and non-hereditary chronic pancreatitis is among the risk factors for pancreatic cancer and thus patients with these diseases should be closely followed up.

Background/aims: The aim of this retrospective study is to follow the main parameters such as the success of performing diagnostic endoscopic retrograde cholangiopancreatography (ERCP) and to determine the effectiveness and morbidity of therapeutic ERCP., Methodology: The study of the group took 12 years (January 1997-December 2008). The paper assesses in retrospect 138 patients who underwent laparoscopic cholecystectomy (LCE). Signs leading to the suspicion of possible biliary complications (BC) after previous LCE appeared in these patients in the postoperative period, indicating the performance of ERCP., Results: Diagnostic ERCP was successful in all 138 patients (i.e. in 100% of cases). There were normal ERCP results in 8 patients and pathological results in the sense of some of the BC in the remaining 130 patients. Endoscopic therapy was performed after diagnostic ERCP in 115 of 130 patients with proved BC. Therapeutic ERCP was absolutely successful in altogether 111 of 130 patients (85.38%) with BC after LCE., Conclusions: The success rate of therapeutic ERCP in our group was 85.38%. Morbidity in relation to therapeutic ERCP was 4.2%. ERCP appears to be highly effective diagnostic and primarily therapeutic method in solving BC after LCE.

Sclerosing cholangitis is a heterogenous disease. Sclerosing cholangitis with an unknown cause is abbreviated PSC. PSC affects extra- as well as intra-hepatic bile ducts and since this is a permanently progressing fibrous condition, it leads to liver cirrhosis. The disease is often associated with a development of cholangocarcinoma and idiopathic intestinal inflammation. Causal therapy does not exist; liver transplantation is indicated. IgG4 cholangitis differs from PSC in a number of features. This form is, unlike PSC, linked to autoimmune pancreatitis (AIP) as well as other IgG4 sclerosing diseases. Anatomically, distal region of ductus choledochus is most frequently involved. Icterus is, unlike in PSC, a frequent symptom of AIP. There also is a distinctive histological picture--significant lymphoplasmatic infiltration of the bile duct wall with abundance of IgG4 has been described, lymphoplasmatic infiltration with fibrosis in the periportal area and the presence of obliterating phlebitis is also typical. However, intact biliary epithelium is a typical feature. IgG4 can be diagnosed even without concurrent presence of AIP. IgG4 sclerosing cholangitis is a condition sensitive to steroid therapy. At present, there is no doubt that IgG4 sclerosing cholangitis is a completely different condition to primary sclerosing cholangitis. From the clinical perspective, these diseases should be differentiated in every clinician's mind as (a) AIP is treated with corticosteroids and not with an unnecessary surgery, (b) IgG4 sclerosing cholangitis is mostly successfully treated with corticosteroids and the disease is not, unlike PSC, a risk factor for the development of cholangiocarcinoma.

Introduction: Pancreatic cancer is a disease with rather poor prognosis. This can be explained, among other reasons, by unusually aggressive course of the tumour growth and, in the majority of cases, late, and thus further treatment limiting, diagnosis. In addition, no effective screening programme for pancreatic cancer is available and thus identification of risk factors associated with the development of pancreatic cancer represents a possible approach to diagnosing early stages of the disease. Smoking represents a general and diabetes mellitus a specific risk factor for pancreatic cancer. The aim of our prospective study in pancreatic cancer patients was to identify patients with diabetes mellitus and divide these into smokers and non-smokers--in association with the diagnosis of pancreatic carcinoma., Materials and Methods: We included 83 patients, 50 men and 33 women, with pancreatic cancer who were divided into 3 groups--non-smokers with diabetes mellitus, smokers and smokers with diabetes mellitus; the mean age was 64.2 years in male and 59.8 years in female patients. Pancreatic cancer was confirmed histomorphologically from pancreatic biopsies or a histology of pancreatic tissue obtained during a surgery., Results: Pancreatic cancer was diagnosed after 3 or more years in patients with diabetes mellitus, the majority of diagnoses in smokers were made within the first year from the first dyspeptic symptoms. We found that the proportion of patients with subsequent diagnosis of pancreatic cancer increased with the number of cigarettes smoked per day (33.3% up to 10 cigarettes per day and 66.5% over 10 cigarettes per day). The highest incidence of pancreatic cancer, in 42 persons (50.6%), was associated with concurrent diabetes and smoking., Conclusion: Pancreatic cancer was identified in 24% of patients with diabetes mellitus, 25.3% of smokers with no diabetes and in more than 50% of smokers with diabetes mellitus. We assume that smoking is an independent risk factor for pancreatic cancer induction and it importantly increases the risk of pancreatic cancer in patients with diabetes mellitus.

Autoimmune LgG4- associated cholangitis is a new entity among the liver and biliary tree disorders, classified among the so-called IgG4-related diseases. Even though prognosis of this disease is unclear, this type of sclerosing cholangitis is not being linked to a carcinoma. Clinical and laboratory data differ slightly from the findings associated with the usual primary sclerosing cholangitis and it is mainly the high IgG4 level and hyperbilirubinaemia that supports the diagnosis ofautoimmune disease. Unlike primary sclerosing cholangitis, this disease is not associated with a malignant prognosis and steroids represent an effective treatment. Combination of steroids with azathioprin is a possible alternative in case of a relapse. Patient's response to steroid therapy is a diagnosis-supporting criterion. This disease should always be considered as part of differential diagnosis of primary sclerosing cholangitis, especially when autoimmune aberrations or other autoimmune diseases are present. Long-term evaluations of these patients are so far lacking and thus studies on larger patient samples are required.

The aim of our work was to determine the incidence of bone demineralization in patients with chronic pancreatitis, following the relation between the funcionality of the pancreatic tissue and etiological factors in the development of osteopathy and calciophosphate metabolism. Prospectivelly, during 1 year we followed 55 patients with chronic pancreatitis of different etiology verified by endoultrasound. Patients with other possible cause of osteopathy were not included in the group. In the following of calciophosphate metabolism we determined different biochemical parameters and we measured the bone mass with densitometry in standard locations. In the patients that we followed we managed to show high proportion (43.7%) of bone demineralization, however, no relation between the bone demineralization and the grade of chronic pancreatitis or the operation of pancreas was proved. Vitamin D deficiency has a significantly negative impact on bone metabolism, which is potentiated by pancreatic insufficiency and long-time alcohol abuse.

Differential diagnosis of abdominal pain is a complex area of internal medicine. The present paper discusses possible aetiology together with characterisation of some other signs, pain localisation, its propagation and diagnosis. The approach to differential diagnosis of abdominal pain must always be comprehensive and span from targeted anamnesis to physical examination of the abdomen and rational application of available, mainly imaging and endoscopic methods. Therefore, we present the most frequent aetiologies of functional and organic impairments ofthe oesophagus, intestines and pancreatic and biliary area, including possible extra-abdominal causes of abdominal pain. It is emphasised that abdominal pain should always be carefully investigated and analysed in order to prevent major mistakes and possible harm to our patients.

Diagnosis and treatment of acute pancreatitis is a complex interdisciplinary team problem. Without knowledge of classification and the current opinion of other experts on this disease, the radiologist cannot be an adequate partner in this team. Nonetheless, the radiologist has a very important position, primarily 'thanks to' computed tomography (CT) in diagnosis and fading of the disease and the possibilities offered by minimally invasive treatment of early and late complications of this disease. A turning point from the viewpoint of diagnosing acute pancreatitis was first marked by Balthazar's classification and then establishing the CTSI (severity index for the disease based on CT findings), proposed by Balthazar as well. Radiologists' increasingly more active approach to drainage of acute fluid collections and pseudocysts in patients with acute pancreatitis as well as some possibilities for percutaneous treatment of necroses has led to a reassessment of surgeons' attitudes. A persistent problem is the correct indication and timing of CT scans and the drainage itself. In their concise communication, the authors present data from the literature and summarize their own experience. They highlight the most common mistakes, especially in the indication and timing of individual methods. Finally, they present their views on a practical approach to the use of CT and percutaneous drainage in these patients., (Copyright (c) 2010 S. Karger AG, Basel.)

Autoimmune pancreatitis (AIP) is recognized as a distinct clinical entity, identified as a chronic inflammatory process of the pancreas in which the autoimmune mechanism is involved. Clinically and histologically, AIP has two subsets: type 1--lymphoplasmatic sclerosing pancreatitis with abundant infiltration of the pancreas and other affected organs with immunoglobulin G4-positive plasma cells, and type 2--duct centric fibrosis, characterized by granulocyte epithelial lesions in the pancreas without systemic involvement. In the diagnosis of AIP, two diagnostic criterions are used--the HISORt criteria and Asian Diagnostic Criteria. In the differential diagnosis, the pancreatic cancer must be excluded by endosonographically guided pancreatic biopsy. Typical signs of AIP are concomitant disorders in other organs (kidney, liver, biliary tract, salivary glands, colon, retroperitoneum, prostate). Novel clinicopathological entity was proposed as an 'IgG4-related sclerosing disease' (IgG4-RSC). Extensive IgG4-positive plasma cells and T lymphocyte infiltration is a common characteristics of this disease. Recently, IgG4-RSC syndrome was extended to a new entity, characterized by IgG4 hypergammaglobulinemia and IgG4-positive plasma cell infiltration, this being considered an expression of a lymphoproliferative disease, 'IgG4-positive multiorgan lymphoproliferative syndrome'. This syndrome includes Mikulicz's disease, mediastinal fibrosis, autoimmune hypophysitis, and inflammatory pseudotumor--lung, liver, breast. In the therapy of AIP, steroids constitute first-choice treatment. High response to the corticosteroid therapy is an important diagnostic criterion. In the literature, there are no case-control studies that determine if AIP predisposes to pancreatic cancer. Undoubtedly, AIP is currently a hot topic in pancreatology., (Copyright (c) 2010 S.

Aims of the Study: The aim of this retrospective study was to analyse diagnostic and therapeutic success of endoscopic retrograde cholangiopancreatography (ERCP) in our sample of patients following Billroth II gastric resection, where, due to significantly modified anatomic ratios, this surgery represents a specific and often extremely difficult technical problem when performing ERCP., Materials and Methodology: The sample was followed up for 13 years (November 1994-December 2007). The data on 112 patients after Billroth II gastric resection were assessed retrospectively; indications for ERCP included cholestasis in 92 patients, acute biliary pancreatitis in 12 patients, acute cholangitis in 6 patients and suspected bile leak following laparoscopic cholecystectomy (LCE) in 2 patients., Results: Cannulation success during ERCP in the 112 patients following Billroth II gastric resection was 90.2% (i.e. 101 of the 112 patients). Normal ERCP finding was recorded in 4 patients. The remaining 97 patients had pathological results on ERCP (choledocholitiasis was found in 78 patients, malignant biliary stenosis in 14, benign biliary stenosis in 3 a bile leak following LCE in 2). Endoscopic treatment was initiated immediately after diagnostic ERCP in all these 97 patients, the initial step was in all cases endoscopic papillotomy using one of the special papillotomes (diathermy wire). Overall, therapeutic ERCP was completely successful in 83 of the 97 patients (85.6% of 97) in whom the originally endoscopic treatment had been initiated., Conclusions: ERCP following Billroth II gastric resection is, due to modified post-surgery anatomy, markedly more challenging then the conventional procedure. Availability of a variety of tools as well as, understandably, extensive experience and skill of an endoscopist are prerequisite to ERCP success in these patients. Correctly performed ERCP in patients following Billroth II gastric resection is a highly effective and safe method for diagnostics and, in particular, treatment of pancreatic-biliary diseases, in which similar success as under standard anatomic conditions can be achieved.

Involvement of genetic factors in the aetiology of inflammatory bowel disease (IBD) has been known for a long time. Our aim was to investigate the prevalence of polymorphisms in NOD2, ICAM-1 and CCR5 genes in Czech and Slovak patients with IBD in comparison with healthy controls. The frequency of well-known mutations (R702W, G908W and 1007fs in the NOD2 gene; K469E in the ICAM-1 gene, and Delta32 in the CCR5 gene) involved in IBD was tested in 45 patients with CD and 22 patients with UC. The allele frequency of these mutations was determined and genotype-phenotype correlation was specified. Isolated DNA was genotyped, and allele frequency was counted and statistically verified. Significant differences between the healthy control group and CD patients were observed in mutation 1007fs of the NOD2 gene (P = 0.0203). We also associated allele E469 of the ICAM-1 gene with CD (P = 0.0024). No significant association between other alleles and CD was found, and no gene variation was linked to UC. The number of mutations and mutated genes was higher among patients with CD than among patients with UC. Our results support previous findings about participation of mutations of NOD2 and ICAM-1 genes in IBD. We confirmed that both CD and UC are polygenic diseases with a genedosage effect. This observation strengthens the opinion that genetic factors play a more important role in CD than in UC.

Objective of Study: The main parameters studied in this retrospective study were the success of diagnoses carried out using endoscopic retrograde cholangiopancreatography (ERCP), the ability of ERCP to precisely determine the cause of complications and the effectiveness and morbidity of therapeutic ERCP., Materials and Method: the study covers a period of 7 years (January 1997-December 2003). The study retrospectively reviewed the histories of 92 patients who underwent laparoscopic cholecystectomy (LCE) and subsequently developed symptoms suggesting possible biliary complications (BC) from previous LCE, and indicating the performance of ERCP., Results: diagnostic ERCP was successful for all 92 patients (i.e. in 100% of cases). In 5 patients the ERCP found normal conditions. In the remaining 87 patients, the ERCP found pathological conditions corresponding to some form of biliary complication. Choledocholithiasis was detected in 59 patients, bile leakage from the cystic duct stump was found in 11 patients, bile leakage from the extrahepatic bile duct was found in 4 patients, biliary stenosis in the common hepatic duct was found in 5 cases and 8 patients had blockages of the extrahepatic bile duct. 10 patients out of 87 received only diagnostic ERCP and all 10 underwent surgery immediately following diagnosis. 77 out of 87 patients with established BC underwent endoscopic therapy after diagnostic ERCP. Therapeutic ERCP was entirely successful for 73 patients out of 87 with BC after LCE (83.92%), and did not require other modalities of treatment such as surgical or transhepatic procedures., Conclusions: In our sample the success rate for therapeutic ERCP was 83.92%. Morbidity relating to therapeutic ERCP was 3.9%. ERCP was shown to be highly effective in both diagnosing and treating BC after LCE.

Minidose acetylsalicylic acid (ASA) administration is a significant risk factor for changes in the stomach and duodenal mucosa also in persons whose anamnesis does not indicate any previous symptoms of stomach disease or any other risk factor. One month ASA minidose therapy provoked changes in the stomach and duodenal mucosa in 43.7% of persons receiving the therapy for cardiologic or neurologic indications. The changes primarily involved erosion and were mainly located on the stomach mucosa, without signs of active bleeding. If ASA minidose therapy was administered for 1 month together with the proton pump inhibitor omeprazole, the rate of incidence of changes detected in the mucosa was statistically significantly lower, i.e. only 27.6 %, again without signs of fresh bleeding. The presence of Heliobacter pylori probably does not play a critical role; Heliobacter pylori was only detected in 34.1% of patients with changes in the mucosa. The persons who need ASA minidose therapy and especially those with risk factors must be secured by drugs with protective effect on the stomach and duodenal mucosa during ASA therapy, specifically in the form of proton pump inhibitors. Considering the benefit and complications of low-dose ASA therapy, it should not be indicated to persons with a low risk of cardiovascular or cerebrovascular complications and should be reserved for the treatment of high risk patients.

Lower dyspeptic syndrome is a bowel disease manifesting namely with pain or sensation of abdominal discomfort and bowel movement problems (changes in the frequency and stool consistency). Symptoms include sensation of intraabdominal pressure and fullness, diarrhoea (with or without pain), sensation of incomplete defecation, constipation or bowel movement problems (with or without pain), irregular stool, collywobbles and bowel content flow (borborygia with spasms), meteorism, flatulency. Prevalence of the Irritable Bowel Syndrome in the European population is estimated to be 5 to 25 %. In the Czech Republic the total prevalence of dyspepsias is about 13 %. To the pathogenesis of the lower dyspeptic syndrome contribute: 1. abnormal motility, 2. abnormal visceral perception, 3. psychosocial factors, 4. luminal factors, 5. imbalance of neurotransmitters and/or intestinal bacteria and 6. possible inflammatory changes of the intestinal mucosa. Infectious diarrhoea is one of the causes. Functional bowel defects represent various combinations of chronic and recurrent symptoms from the digestive tract which cannot be explained by structural or biochemical abnormalities. Irritable bowel syndrome is a functional defect manifesting with abdominal pain, intestinal dyspepsia and compulsive defecations. Subtypes with typical symptomatology are characterized by circumstances which bring about pain and compulsive defecations (morning fractional defecation, postprandial defecation, debacles). Functional diarrhoea manifests with diarrhoea without intensive pain. Spastic obstipation manifests by abdominal pain, obstipation, compulsive defecations are absent, stool is cloddish, fragmented by spastic haustration, or it has a ribbon-form. Changes in the intestinal chemism include fermentative and putrefactive dyspepsia. Among the incomplete and atypical forms the isolated meteorism, irregular defecation, flatulency, abdominal pain--syndrome of the left or right epigastium or the syndrome of the right hypogastrium can be included. In patients with typical set of symptoms the working diagnose of the lower dyspeptic syndrome can be done by general practitioner. Complete history of the disease can reveal possible extra abdominal cause of dyspepsia, recognise alarming symptoms and consider circumstances elevating or lowering the probability of functional problems. Functional bowel problems have usually long-term character and represent clinically demanding challenge. Only few therapeutic regimens are successful and the therapy aimed at the abolishment of one symptom need not bring general improvement. For the clinical studies of the therapy of functional bowel problems significant placebo effect is typical. Quoad vitam prognosis is good, quoad sanationem it is rather doubtful.

Background/aims: Acute bleeding from esophageal varices due to portal hypertension is a frequent and severe complication of liver cirrhosis. The development of esophageal varices as well as their rupture depends on the level of portal pressure; however, a number of other factors may play a negative role in the rise of bleeding and its prognosis., Methodology: The report presented has compared a set of 46 patients admitted to hospital for acute bleeding with 48 cirrhotics hospitalized for other reasons., Results: Bleeding patients had significantly higher level of nitrogenous substances (urea 14.1 mmol/L vs. 7.78 mmol/L, p < 0.01, creatinine 129.8 micromol/L vs. 106.04 micromol/L; p = 0.09). The disturbed renal function in itself probably does not increase the risk of bleeding, it may be rather considered a certain prognostic index of the portal hypertension degree. Bleeding patients had a lower level of total protein (60.7 g/L vs. 69.9 g/L; p < 0.01) with only slight insignificant decrease of albumin (26.64 g/L vs. 28.51 g/L). Cirrhotic patients are known to suffer from malnutrition and it is possible that malnutrition shares negatively and directly in the rise of bleeding., Conclusions: A prognostic index of mortality was a more conspicuous disorder of hepatic function (bilirubin 97.4 micromol/L vs. 57.4 micromol/L; p = 0.1; prolonged prothrombin time 1.99 INR vs. 1.56 INR; p = 0.01) and again the disorder of renal function (creatinine 166.7 micromol/L vs. 114.9 micromol/L; p = 0.09). Therefore, the maintenance of good renal function must be a component of complex therapy given to bleeding patients.

The purpose of the study was to verify effects of Escherichia coli Nissle (Mutaflor) on intestinal colonisation, endotoxin levels, hepatic encephalopathy and liver function in patients with liver cirrhosis. The study involved 39 patients (22 taking Mutaflor and 17 taking placebo). Even though the number combination test showed extended reaction time in patients with described minimal hepatic encephalopathy the drop was not significant in the trend evaluation. However, the treated group displayed significant improvement of intestinal colonisation (p < 0.001) and a trend towards significant reduction of endotoxin levels on day 42 (p = 0.07) and improvement of liver function assessed with the Child-Pugh classification on days 42 and 84 (p = 0.06). Probiotic preparations can therefore represent a significant contribution to this group therapy.

Objective: To determine the prevalence of bacterial infection in patients admitted to hospital with variceal bleeding in comparison with patients with liver cirrhosis admitted because of another reason. To compare the effect of orally administered antibiotics vs. intravenous antibiotics., Methods: Bacteriological investigation of blood culture, urine, throat smear, perianal smear and ascites (polymorphonuclear count as well in ascites) was made in 46 cirrhotic patients admitted to hospital with variceal bleeding and 48 cirrhotic patients admitted because of another reason. Bleeders were treated endoscopically (sclerotization) and pharmacologically (terlipressin 1 mg every 4 h for 5 days), and were randomly allocated to the treatment with oral norfloxacin (25 patients) or intravenous ampicillin/sulbactam (21 patients). Early and late mortalities were evaluated., Results: The incidence of infection was high in both groups (63.0% bleeders vs. 54.2% controls), but bleeding patients more often had positive blood culture (17.3% vs. 8.6%) and statistically significantly more positive findings in the throat smears (36.9% vs. 17.3%, P=0.04), which gives the evidence of increased pathological colonization in these patients. No difference in survival was seen in patients with per-oral or intravenous administration of antibiotics., Conclusion: Bacterial infection was demonstrated in high percentage in patients with liver cirrhosis admitted to hospital. The administration of antibiotics is indicated in these patients. Intravenous application is probably of the same efficacy as per-oral one.

Background/aims: Acute bleeding from the upper gastrointestinal tract is a common and serious complication of liver cirrhosis. It is believed that bacterial infection may be the immediate cause of the bleeding and the latest meta-analyses show that bacterial infection is an independent predictive factor of the failure to stop bleeding., Methodology: The authors evaluated the presence of bacterial infection (blood, urine, throat and ascitic fluid) in 35 consecutive patients with liver cirrhosis and acute bleeding with portal hypertension and compared these results with a group of 35 patients with liver cirrhosis with portal hypertension without acute bleeding., Results: According to the results obtained, there is a statistically higher incidence of bacterial infection among patients with acute bleeding with portal hypertension (25 of 35 patients, 71%) than among patients with liver cirrhosis and portal hypertension without acute bleeding (14 of 35 patients, 40%, p < 0.01). The incidence of bacteriological findings in blood and throat samples is statistically higher in patients with acute bleeding as opposed to the control group (p < 0.05)., Conclusions: These results confirm the necessity of administering antibiotic prophylaxis to all cirrhotic patients with variceal bleeding, not just to those with confirmed infection or symptoms thereof.

Background: The understanding of different management strategies in primary and secondary care is important for cooperation between specialists and general practitioners in clinical practice. The Institut of General Practice at First Faculty of Medicine carried out a survey for gastroenterologists concerning their opinions on general practitioners and their current knowledge, competence and management of GI disorders as a contribution to interdisciplinary communication., Methods and Results: Questionnaires were sent to 552 gastroenterologists in the country. There was a response rate of 31% without any reminder, 170 questionnaires were included in a study. The most of gastroenterologists (92%) support practical guidelines development. There is an insufficient confidence that these guidelines are implemented in practice. Four from five gastroenterologists consider knowledge of their colleagues GPs in gastroenterology as average. In particular cases (irritable bowel syndrome, step up and step down approach) are specialists rather sceptic. There is a low support for the increase of GP competence in gastroenterology, as for urea breath test availibility, particularly in private gastroenterologists (p=0,04)., Conclusions: Results of the survey could facilitate the interdisciplinary communication in gastroenterology, contribute to CME programs development and may serve as an example for other specialities.

An acute bleeding from oesophageal varices as a result of portal hypertension is a frequent and serious complication of liver cirrhosis. The development of oesophageal varices and their rupture depends on the portal pressure. However, a range of other factors can contribute to a development of bleeding and its negative prognosis. A sample of 46 patients admitted for the acute bleeding has been compared to 48 cirrhosis patients hospitalised for other conditions in this work. There were significantly higher levels of nitrogenous matters in bleeding patients (urea 14.1 mmol/l vs. 7.78 mmol/l, p < 0.01, creatinine 129.8 micromol/l vs. 106.04 micromol/l, p = 0.09). Perhaps it can't be said that impaired renal functions alone increase the risk of bleeding. From this point of view they could rather be seen as definite prognostic markers of the degree of portal hypertension. Moreover, there was a decreased level of total proteins in bleeding patients (60.7 g/l vs. 69.9 g/l, p < 0.01) at a mild nonsignificant decrease of albumin (26.64 g/l vs. 28.51 g/l). Cirrhotic patients are known to suffer from malnutrition and there is a possibility that malnutrition can contribute to development of bleeding. A prognostic marker of mortality was a considerable impairment of liver function (bilirubin 97.4 micromol/l vs. 57.4 micromol/l; p = 0.1 and prolonged prothrombin time 1.99 INR vs. 1.56 INR; p = 0.09) and impaired kidney function (creatinine 166.7 micromol/l vs. 114.9 micromol/l, p = 0.09). Therefore a care of a good renal function must be a part of the complex care of bleeding patients.

An acute bleeding from oesophageal varices as a result of portal hypertension is a frequent and at the same time serious complication of cirrhosis of the liver. One of factors influencing this bleeding can be a bacterial infection. Endotoxines can increase portal pressure and so participate in development of bleeding and simultaneously deteriorate a patient's prognosis. An antibiotic treatment is a part of a treatment algorithm, however what antibiotics to administer and in what manner is unclear. A group of 46 patients who were admitted to a hospital for an acute bleeding from varices has been compared in the study to 48 cirrhosis patients hospitalised for other reasons. An infection incidence was high in both groups (63.0 % vs. 54.2 %), bleeding patients had more often positive hemoculture (17.3 % vs. 8.6 %), and statistically significantly more often positive findings in throat swab culture (36.9 % vs. 17.3 %, p = 0.04) which is an evidence of an increased pathology colonisation of these patients. Bleeding patients were randomised for peroral norfloxacin administration (n = 25) or an intravenous administration of a combination of ampicilin and sulbactam (n = 21). There was no difference in survival of both groups. Due to a high number of bacterial infections antibiotics administration has been indicated in these patients. Intravenous administration is probably of the same effect as peroral administration.
