[ correlation between helicobacter pylori infection and squamous cell carcinoma of larynx and hypopharynx]

From the most important laryngeal and hypopharyngeal cancer risk factors are smoking, alcohol and anemia. But reflux is one of the suggested etiologies. Pregnancy, Nonstroidal anti inflammation drugs and drugs decreasing the lower esophageal sphincter pressure will increase the reflux. Helicobacter pylories role in reflux formation is different due to the involved region and can also have a decreasing role and decline the rate of a series of esophageal and upper aero digestive system disease. This cross - sectional and case - control study was done in Qaem medical hospital, Mashhad during the years 1384 and 1385, for serum level detection of anti -H.pylori IgG and IgA antibodies in blood samples of both control and case groups. The variables were age, sex and serum test results. 45 patients [39 male and 6 female] and 42 controls [33 male and 9 female] were evaluated. 2 groups were matched for age and sex. Positive IgG and IgA results in patients in order was 3 person [6.6 percent] and 3 person [6.6 person] and in control group 26 person [61.9%] and 12 person [28.5%]. Result [P>0.001] was for healthy group showing the protective effect of H. Pylori against laryngeal cancer. In our study, control group with a meaningful difference was affected by H.Pylori infection. This can be due to a protective effect for H. Pylori against the laryngeal and hypopharyngeal malignancies. Prospective studies and simultaneously evaluation of reflux, H. Pylori infection and the regain of gastric location are suggested

[ case of polypoid sygmoid endometriosis like to colon cancer]

Ntestinal endometriosis is a rare but clinicaly significant complication. The most commonlly involved sites are the rectosigmoid and rectovaginal septum. Although serosal involvement is not uncommon in women of child bearing age. The mucosal involvement is rare and differential diagnosis from colon cancer may be difficult due to the lack of pathogonomonic symptoms and the poor diagnostic yield of colonoscopy and colonic biopsies. We present a case of a 31-year young woman with sigmoid endometriosis is presented with rectal bleeding in which the initial diagnostic workup suggested colon cancer. Histological evidence obtained from a colonoscopy along with clinical history Led to the final diagnosis of intestinal endometriosis
