The aims of this study was concerned on the evaluation the etiology of diarrhea (parasitic (E. histolytica and G. lamblia) and Celiac disease in children under five years and its effectiveness on the some laboratory investigations which is the complete blood picture (CBP), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP), the sero-prevalence of celiac disease; in which two types of autoantibodies was studied, anti-gliadin (IgG and IgA), and anti-tissutransglutaminase (IgG and IgA); A total of 67 children with diarrhea have been diagnostic, E. histolytica recorded the largest group 36 sample followed by G. lamblia 23 sample, and Sero-positive celiac disease only 8 children. the E. histolytica was mostly at 4-5 years (36.1%) and G. lamblia was mostly in age 1-2 and 2-3 years (30.4%). we found that most of neutrophilia and eosinophilia cases were in E. histolytica and G. lamblia. Hemoglobin concentration show a significant decrease in patients with diarrhea. Abnormal ESR and CRP titer reading has been in shows higher mean values with E. histolytica and Sero-positive celiac disease then followed by G. lamblia.

Background: H. pylori infection invariably causes active chronic gastritis. In most people, this may be clinically silent throughout life, but in a substantial minority, it causes gastroduodenal diseases Objective: The study was designed to investigate the risk factors associated with perforated peptic ulcer. Patients and materials: In this study involved 51 consecutive patients (32 male and 19 femle) aged from (<20- >50) who underwent endoscopic examination by specialist doctors, all patients were interviewed regarding personal bio data (age, sex, job, marital status, and place of residence), selected risk factors (smoking status, NSAID use, soft drinks, stress, Caffeine, blood group, whether food was spicy or not, family history of peptic ulcer, and presence of chronic comorbidities Results: the result showed great variation between risk factors (32/62.7%) from samples was smoking ,(26/51%) of them drink carbonated drinks , (44/86.3) unusual drink of Caffeine, (43/84.3%) had an extremely stress , (30/58.8%) add spices to meals ,(41/80.4%) of them use NSAIDs, while (29/57%) of them had a family history of Infection of peptic ulcer anther wise the blood groups for all patients samples ,the blood group O was the highest incidence between them and record (25/49%) ,while the( RH+) factors was high in studied samples( 41/80%) in comparison with (RH-) . Conclusion: These findings suggest that if gastric acid has a role in acid-peptic symptoms and/or healing, milk is not a suitable therapeutic option. The benefit of milk against an appropriate placebo on symptoms or healing in people with acid-peptic illnesses has not been carefully investigated.
