[Colonoscopic and histopathological findings in patients with hematochezia]

Colonoscopy is the best method for management of patients with Hematochezia or lower gastrointestinal bleeding [LGIB]. This study was conducted to assess the endoscopic and histopathologic findings in patients with hematochezia. This descriptive -analytical study was done on 117 [50 males, 67 females] patients whom referred to 5th Azar hospital in Gorgan, northern Iran during 2010. Demographic characteristics, medical history and colonoscopic and histopathologic findings were recorded for each patient. Hemorrhoid was the most common finding in colonoscopic examination. Inflammatory bowel disease [IBD] and cancer were the most common feature in the under and higher than 43 age old patients, respectively [P<0.05]. Ulcerative colitis [22.2%] was the most common finding in histopathological examination. Rectosigmoid was the most common anatomical location of involvement in IBD cases. Cancer and IBD were occurred in the left colon. Flexible sigmoidoscopy can be a selected procedure for evaluation of hematochezia in the <43 age old patients but in >43 age old subjects sigmoidoscopy or colonoscopy should be made based on patients' status

[Comprehensive evaluation of patients with history of burning in shaheed Mohammadi Medical Center in Bandar Abbaas during 1381-1382]

Backgroand: thermal burns and related injuries are among major causes of death and disability. The introduction of burn centers causes improvement in survival and reduction of morbidity in patients with the history of burning

Materials and methods: this is a retrospective study on burned-patients hospitalized in burn ward of Shaheed Muhammad, Medical Center of Bandar Abbas, which is the only burn ward of Hormozgan province and neighbor cities. The information obtained from patients files

Results: total number of patients was 409. There were 215 [52.5%] males and 194 [47.5%] females. Most patients had II, III degree of burn and were divided in 10 groups from 10% of T.B.S.A to 90%. The age groups of 1- 5 years old and 15- 30 years old had the most patients, which the most mortality rate was in these groups. On the other hand, age group of 55- 60 years old had the least patients. The mean of burn area was 48% of T.B.S.A. The total number of death was 156, 60 males and 64 females

Concluasion: more than 90% of burns are caused by carelessness or ignorance which is completely preventable. Introduction of equipped and specific burn centers is on of the most important arid essential needs of the HOrmozgan province teaching to people via T.V or during their education at school will reduce burn injury and its morbidity

[Isolation of helicobacterpylori with PCR method from oral aphthous of patients with recurrent aphthous stomatitis in Rasht in 2002]

Introduction: recurrent aphthous stomatitis [RAS] is a disorder, which is characterized by ulcers restricted to oral mucousa. Regarding the inspection of histological similarities between peptic ulcers and recurrent oral aphthous and the response of RAS to the broad-spectrum antibiotic treatment such as tetracycline and the identified role of H.pylori in peptic ulcers, the possibility of bacterial involvement in the progression of oral aphtous ulcers has been suggested. Hence, there are limited evidence available for colonization of H. pylori and its probable role in induction of oral aphthouse ulcers

Objective: we aimed to distinguish the probable presence of H.pylori in brushed sample of oral aphthous ulcers by PCR method

Materials and Methods: in this study, we sampled the oral aphtous ulcers with the toothbrush in patients with RAS. PCR which is a very precise and sensitive technique for isolation of H. pylori in ulcer samples of recurrent aphthous stomatitis and in samples from other parts of the oral cavity. Serologic tests such as ELISA were also done in all patients for determination of IgG antibody. Both PCR and ELISA were done in all patients. Evaluated patients were people presenting to the laboratory with the diagnosis of RAS, from the beginning of 2001 till the end of 2002

Results: study patients were between 18 to 60 years old and the average age among them was 32/38 +/- 11/30. 26 patients [52%] had positive ELISA test and we obtained H.pylori DNA in one patient [2%] in a total of 50 evaluated patients

Conclusion: according to the results of this study, H. Pylori DNA can't be found in aphthous ulcers of these patients, even in those with positive anti H. Pylori, anti body [IgG] results. And it is probable that these bacteria aren't involved in oral recurrent aphthous ulcers
