They were classified by their socioeconomic status; in the following categoris: High (level I n = 0); Medium-High (level II n = 50); Medium-Low (level III, n = 50); Low (level IV, n = 50); and Very Low (level V, n = 50). The percentage of positivity ofr serum HAV ab was: Level II: 12%, Level III: 18%, Level IV: 38% and Level V: 40%. The difference between levels II and III and between levels IV and V was no significant (p > 0.05), but after making a comparation between levels II and III as a group and levels IV V as another one, we found a statistical significant difference (p < 0.005). We concluded: There is a bimodal behavior for the prevalence of serum HAV ab in our study: one group with high prevalence (78%) and another one with low prevalence (30%). The massive Vaccination government programs and the vaccionation in particular cases in the daily medical practice should be done after assessing the personal Socioeconomic status in order to improve the use of this tool and achieve a progressive reduction in the morbiditi and high endemicity of HAV in our city.","PeriodicalId":75872,"journal":{"name":"G.E.N","volume":"49 4","pages":"263-6"},"PeriodicalIF":0.0,"publicationDate":"1995-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19736103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PEG have many advantages over the surgical gastrostomy. In this paper, we present our experience with the use of PEG in patients with head and neck cancer using a new home made gastrostome. Included were 61 patients 37 males (64.8%), 21 females (36.2%) with ages betwen 11 and 72 years. In 3 patients the PEG was not intended because tight esophageal stenoses. The PEG was completed in 56 cases (91.8%). In 5 patients (8.6%) there were minor complications (4 infections and 1 patient with pain). We have only one case of major complication which consisted in migration of gastrotome to the abdominal wall (Buried Bumper Syndrome). The gastrostome was patent between 15 and 312 days with a median of 125 days. The gastrostomies was made with siliconed 22Fr Foley catheter, crazy glue, and plastic tops. The Foley catheter is acid resistant and not deteriorate like other materials like latex. There was not adverse reaction at the ostomy site. The cost of the kit is about 11 US$ and the commercial kit is 125 US$, on the other hand the internal diameter is 15% wider than the commercial one.","PeriodicalId":75872,"journal":{"name":"G.E.N","volume":"49 4","pages":"278-85"},"PeriodicalIF":0.0,"publicationDate":"1995-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19736104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this work is to evaluate three microbiologic methods for diagnosing H. pylori infection. We studied 375 samples from 218 patients, who consulted at the Department of Gastroenterology of the Hospital Vargas and were candidates for endoscopy. Samples of gastric mucous tissue were taken at level of the antrum and each sample was stained with Gram, tested for urease and cultured.Results: whit H. pylori positive 123 patients with duodenal ulcer at the endoscopy (91.1%), 17 had gastric ulcer (76.5%), 40 gastritis and/or duodenitis (60.0%), 1 duodenal ulcer and gastric (100.0%) and 37 normal endoscopies (56.8%). Evaluating the three methods used we found that of the 286 H. pylori positive samples, the Gram stain detected 282 (sensibility 98.6% and specificity 96.6%); the urease test 276 (sensibility 96.5% and specificity 98.6%) and culture was positive in 255 samples (sensibility 89.2% and specificity 100.0%). These results show that both the Gram stain and Urease test are useful for diagnosing H. pylori infection due to their high sensitivity and specificity, rapidness, low cost for the Gram stain, and easy interpretation for Urease test. Culture, even though less sensitivity++, represents the most unquestionable diagnosis and permits carrying out susceptibility to antimicrobials tests.","PeriodicalId":75872,"journal":{"name":"G.E.N","volume":"49 4","pages":"292-5"},"PeriodicalIF":0.0,"publicationDate":"1995-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19735388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of them hospitalized at the gastroenterology service. The serovar most frequently found was icterohemorragiae 11 cases. There was a predominium for the male gender 12/2 and the majority of patients belonged to the range of age between 31 and 40. The most common forms of presentations were: fever (14), jaundice (10) and myalgias (10) while the most relevant findings at physical examination were: jaundice (12), fever (11) and hepatomegaly (8). All patients had abnormal laboratory tests and among these, aminotransferases, bilirrubin, creatinin, CPK, platelets and urinary sediment were more frequently altered. Only half of the patients were diagnosed as Leptospirosis at the moment of admission. We conclude that even though Leptospirosis is an infectious disease distributed worldwide only few cases are hospitalized and differential diagnosis is difficult because of diversity of clinical presentations and lack of laboratory resources. It is important for gastroenterologists because most of complicated cases present as jaundiced patients.","PeriodicalId":75872,"journal":{"name":"G.E.N","volume":"49 4","pages":"273-7"},"PeriodicalIF":0.0,"publicationDate":"1995-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19735389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
