[Rate of prevalence of helicobacter pylori infection in primary gastric lymphoma patients referring to pathology centers of Yazd]

Lymphomas as a group rank seventh as the most leading cause of death in cancers. Stomach is the most common extra nodal site of primary lymphomas. On the other hand, new information demonstrates that MALT lymphoma responds to Helicobacter antibiotic therapy. We therefore decided to determine the frequency of distribution of Helicobacter Pylori infection in primary gastric lymphoma cases at the pathology centers of Yazd and determine the relationship of Helicobacter Pylori infection with sex, age and chief complaint of these patients. This was a case series and cross-sectional study and population included patients referring to pathology centers of Yazd for whom diagnosis of primary gastric lymphoma had been suggested. Required data was accumulated with assessment of pathology reports and hospital folders of patients. Also, tissue blocks of studied patients were evaluated for presence or absence of Helicobacter Pylori. After completing the questionnaire, data was analyzed statistically using SPSS 13, ANOVA and Fisher's Exact tests. 28 patients were included in this study. Prevalence of Helicobacter Pylori infection in the study group was 43.5% and more in female patients and patients aged above 45 years. Helicobacter Pylori infection was more in patients who had dyspepsia as their chief complaint and those with ulcer on endoscopy. Also, the frequency was more in high grade lymphoma cases. In this study we didn't achieve a statistically significant correlation between primary gastric lymphoma and Helicobacter Pylori infection. We suggest further studies with larger number of cases to determine the prevalence of various grades of lymphoma and their relationship with Helicobacter Pylori in other provinces with conditions similar to Yazd

[Role of obesity in premature MI occurrence and hospital and one year follow up mortality]

Nowadays, obesity is developing as an epidemy and it is one of major risk factors of coronary artery disease, therefore this study determinated the effect of obesity on age of occurrence of MI and It's mortality. In this prospective study we studied on 212 hospitalized patients because of MI in CCU[s] from May 2001 to October 2002 and they followed for one year, questionnaires for all patients were completed and data analyzed with SPSS ver.11.00.. 34.9% of patients were overweight and 16.5% were obese. Average BMI was 25.87 +/- 4.38. Obese patients were younger than overweight and normal weight patients significantly. [P=0.039] there was a linear relationship between BMI and age of occurrence of MI. [P=0.005]. Obesity and overweight status didn't affect on hospital and late [1 year] mortality. According to our results, obesity associated with premature occurrence of AMI because obesity accelerated coronary atherosclerosis but obesity didn't associate with increased incidence of inhopsital or one year mortality. Thus we suggest to long term follow up in later studies
