| 1 | Helicobacter pylori may be an initiating factor in newly diagnosed ulcerative colitis patients: A pilot study显示文摘AIM To directly visualize Helicobacter pylori(H. pylori) by the highly sensitive and specific technique of immunohistochemical staining in colonic tissue from patients newly diagnosed with ulcerative colitis(UC).METHODS Colonoscopic biopsies from thirty patients with newly diagnosed UC and thirty controls were stained with Giemsa stain and immunohistochemical stain for detection of H. pylori in the colonic tissue. Results were confirmed by testing H. pylori Ag in the stool then infected patients were randomized to receive either anti H. pylori treatment or placebo.RESULTS Twelve/30(40%) of the UC patients were positive for H. pylori by Giemsa, and 17/30(56.6%) by immunohistochemistry stain. Among the control group 4/30(13.3%) and 6/30(20 %) were positive for H. pylori by Giemsa and immunohistochemistry staining respectively. H. pylori was significantly higher in UC than in controls(P = 0.04 and 0.007). All Giemsa positive patients and controls were positive by immunohistochemical stain. Four cases of the control group positive for H. pylori also showed microscopic features consistent with early UC.CONCLUSION H. pylori can be detected in colonic mucosa of patients with UC and patients with histological superficial ulcerations and mild infiltration consistent with early UC. There seems to be an association between UC and presence of H. pylori in the colonic tissue. Whether this is a causal relationship or not remains to be discovered. | Loai Mansour Ferial El-Kalla Abdelrahman Kobtan Sherief Abd-Elsalam Mohamed Yousef Samah Soliman Lobna Abo Ali Walaa Elkhalawany Ibrahim Amer Heba Harras Maha M Hagras Mohamed Elhendawy | 2018 | World Journal of Clinical Cases2018，6，13： | 4 |

| 15 | Impact of the socioeconomic status on the severity and outcome of community-acquired pneumonia among Egyptian children: a cohort study显示文摘Background:Community-acquired pneumonia(CAP)is one of the five leading causes of death among children in developing countries,accounting for approximately three million deaths per year.Identification of the modifiable risk factors of CAP may help to reduce the burden of this disease.In this study,the impact of the socioeconomic status(SES)on the severity and outcome of CAP among Egyptian children was studied.Methods:This was a prospective longitudinal cohort study which included 1,470 children diagnosed with CAP,aged two to 15 years(median age 5.4 years).The diagnosis of CAP was based on clinical and radiological findings.A structured questionnaire and the patients’medical records were used for the data collection.The subjects were divided into two groups:mild and severe CAP.Social and demographic variables were compared,and a multivariate logistic regression analysis was performed.Results:The multivariate analysis showed that a low maternal education level(OR:3.8;95%CI:2.12-6.70;P=.0001),unavailability of adequate medical care(OR:3.1;95%CI:1.99-4.88;P=.0001),a low family income(OR:2.2;95%CI:0.99-4.78;P=.047),and parents’smoking habits(OR:2.0;95%CI:1.15-3.55;P=.014)were significant independent predictive risk factors for severe CAP among Egyptian children.Conclusion:Public health measures against these socio-demographic risk factors should be identified as priorities in order to help reduce the disease burden of deaths from severe CAP among Egyptian children. | Seham Fathy Abdel Hameed Azab Laila M Sherief Safaa H Saleh Wafaa F Elsaeed Mona A Elshafie Sanaa M Abdelsalam | 2014 | Infectious Diseases of Poverty2014，3，1： | 1 |
