    ABSTRACT: Unlabelled: In Argentina almost 7% of deaths are due to different cancers with screening strategies. Objectives: Evaluate knowledge about cancer prevention compared with other tumors. Materials. A descriptive and comparative study. A survey between April and June 2013 in Salta City, province of Salta, Argentina. Correct answers were considered. Statistical analysis: Descriptive (mean and percentage), comparative Chi square Test (significance level P<0,05). Results: 100 surveys. Correct answers: 36% Colon (CI 0,27-0,45), 46% Prostate (CI 0,33-0,52) and 69 (CI 0,59-0,77) and 58 (CI 0,48-0,67)for mama and cervix. 20% (CI 0,13-0,28) knew that colon cancer has a genetic predisposition and 58% (CI 0,48-0,67) about mama. 73% (CI 0,63-0,8) received information about cancer prevention. The main source of information was the physician. 46% (CI 0,36-0,55) received medical care in private institutions. Those who had social security, higher educational levels and medical care in private institutions had better knowledge about cancer prevention except in colon cancer. Conclusions: The global results showed levels below 70% in general but extremely low in colon cancer. Not having social security, receiving medical care in public institutions and having a low educational level are related with poor knowledge about cancer prevention except for colon and prostate cancer.

    ABSTRACT: Recommendations for Hepatitis C screening based on risk factorsfor transmission proved to be ineffcient. Accordingly, the CDC recommended to screen all American individuals born between 1945-1965, based on data from population prevalence of infection. The effectiveness of implementing these recommendations in other contexts and/or populations can be estimated, in principle, knowing the age distribution of infected individuals. There is no data on population prevalence in our country. Yet we can know the age distribution of cases of Hepatitis C who accessed the health system. The aim of this paper is to analyze the distribution by birth cohort ofcases registered as "Hepatitis C" in the Sentinel Units for Viral Hepatitis in the 2007-2014 period. This will contribute to the identification, if any, ofa cohort in which case the recommendation of screening could be addressed, based on risk factors inherent to our country and our epidemiological reality. The age distribution of our cases was wider and younger than those of the population supporting the recommendation of the CDC and this suggests -beyond the difference in the populations being compared- is due to a range of risk factors and age at different infection between USA and Argentina. Thus, based on these results, the recommendation of the Argentine Consensus for Hepatitis C in 2013 to screen all individuals once in life is supported.

    ABSTRACT: prevents, in pancreocytes, the evolving of a "supramaximalecbolic-stimulation" process. The PP involvement as a modulating agent of pancreon's reactivity is reflected by the progressive increment of its plasma values in the first week of an evolving AP episode. In the AP associated to a large meal, an overpowering of the pancreon's brake might have a pivotal role. In experimental and clinical chronic alcoholism, a vagal neuropathy of the Pavlov inhibitory fibers that, as a consequence, impairs the pancreon's brake through a depression of PP secretion is at the basis of an enhanced reactivity of the duodeno-pancreatic reflexes. The latter leads to intrapancreatic cholinergic hypertonus and to Vater papilla's dysfunction. These changes, plus an enhanced pancreocyte's response to CCK, are at the core of acinar cell "supramaximal stimulation" with the organelle disruption that process implies. The intrapancreatic cholinergic hypertonus, the enhanced exocrine cell reactivity to CCK stimulation, and the augmented resistance to the pancreatic secretion flow at Oddi sphincter, explain the aggravating influence of chronic alcoholism on an episode of acute biliary pancreatitis. As the PP secretion, normally elicited by secretin, CCK, food and insulin hypoglycemia, is depressed in the presence of an augmented number of PP cells, as it is in the cases of chronic alcoholics, cystic fibrosis patients and, also, in dogs with pancreatic fibrosis (ductal ligation), it has been inferred, besides our postulated impairment of the Pavlov inhibitory fibers in the vagus nerves, that the defect of PP release is localized to the common final pathway of the above stimuli, probably in or near the PP cell itself This review was prompted by the unexpected experimental finding in canines that Tissucol-induced pancreatic ductal blockade elicits Pancreatic Polypeptide (PP) release and seems to be at the basis of the beneficial effects on taurocho- late-induced acute pancreatitis (AP). In the release mechanism of this regulatory peptide secreted by PP cells located in the periphery of Langerhans islets and scattered in the ductal epithelium, two neuroendocrine reflexes (NER) are involved. The "short" NER is evoked from the duodenum by an unknown component of bile-pancreatic secretion. The "long" NER is triggered by a vagovagal reflex. PP induces a depression of the intrapancreatic cholinergic tone. On the one hand suppressing, hormonally, nervous impulses discharge from the vagal nuclear complex in the brainstem. On the other, interfering paracrinically on the cholinergic transmission by acting, presynaptically, on post-ganglionic cholinergic neurons. The resulting PP-evoked fall of the intrapancreatic cholinergic tone depresses the hormone induced (secretin, CCK) pancreons secretory response. PP, with other agents, contributes to the "fail-safe" system or pancreon's brake that

    ABSTRACT: Unlabelled: Endoscopic radiofrequency ablation makes use of warm energy to ablate the esophagus's surface where the epithelial anomaly is located. Patients and methods: 50 adults patients with the diagnosis of EB according to Vienna Classification were included. Objectives: To evaluate the security and efficacy of ARF in patients with EB. Results: 50 ARF treated patients were included with a medium follow up of 18 months. The median age was 58 years. 1.4 sessions of ARF perpatient were made to obtain EB erradication. The procedure morbidity was 6%, the more frequent complication was the esophageal stenosis (two cases). During the follow up, intestinal metaplasia recurrence was not observed. Conclusions: In the experience of our team, ARF is a secure procedure with low morbidity. These observations added to the published results help to evaluate the currentfollow up protocols.

    ABSTRACT: Colonic lipomas are a rare entity, even lessfrequent colonic lipomatosis (lipohyperplasia) of which we only found very few reports in literature (five cases). We report a case of colonic lipomatosis in a young adult that manifested as acute diverticulitis with perforation and rectalpolyposis requiring surgical resolution.

    ABSTRACT: Hemobilia is defined as the presence of blood in the biliary tree characterized by the triad: jaundice, right hypochondrium pain (RH) and upper gastrointestinal bleeding (UGB). Among the etiologies highlighted in order of frequency there are: liver trauma (accidental and iatrogenic), inflammatory causes (acute and chronic cholecystitis), infections (cholangitis, liver abscesses, parasitic infections) and vascular diseases (aneurysms, vasculitis, arteriovenous malformations). There exist many complementary tests for the diagnosis of hemobilia, such as imaging (abdominal ultrasound, CT scan, angio CT), videoendoscopy, endoscopic retrograde cholangiopancreatography and angiography, the latter being considered the diagnostic tool and therapeutic modality of choice. We report the case of a 52-year-old male patient with hemobilia secondary to apseudoaneurysm ofthe hepatic artery, along with a review of the existing literature.

    ABSTRACT: Tufting enteropathy (TE), previously known as intestinal epithelial dysplasia, is a rare congenital enteropathy characterized by refractory diarrhea in the neonatal period. It presents clinical and histological heterogeneity and may be associated with birth defects and punctuate keratitis. The causative gene(s) have not yet been identfied making prenatal diagnosis unavailable. Although there are milder phenotypes most require parenteral nutrition for prolonged periods with the risk of complications. TE becomes an indication for intestinal transplantation. We report the case of a 4-month-old male, born full term with a normal weight. The parents consulted because of severe malnutrition and chronic watery diarrhea. Duodenal and rectal biopsy was negative. Because of poor tolerance gastroclysis was changed to parenteral nutrition. The infant had several catheter-related infections and died at 13 months from catheter-associated complications. Histopathological autopsy was performed. The material was fixed in paraffin and studied with routine techniques. PAS and immunohistochemistry for CD10 were performed. We observed villous atrophy with intestinal epithelial dysplasia and disorganization on the surface of epithelial cells resembling tufts in jejunal and ileal tissue. The objective of this study was to present a rare case of neonatal enteropathy, especially TE, describe the methodology used to study the biopsy, and discuss the differential diagnoses. TE is a rare neonatal enteropathy that is difficult to diagnose and manage. Children in whom TE is suspected should be referred to specialized pediatric centers, with the option of intestinal transplantation.
