Is Helicobacter pylori infections in immunocompromised children a risk factor for cancer?

The frequency of Helicobacter pylori in children with malignancy was evaluate in the present study. Among 51 children included in the study, 29 children were in malignancy group [79.3% of them having positive one step diagnostic test], while 22 children were control group [54.5% of them having positive one step diagnostic test].h.pylori infection was significantly higher in the malignancy group comparedto the control group [P<0.05]; 44.8% having positive culture for H.pylori, while only 18.2% of control having positive culture for H.pylori. the results showing that there is no significant association between H.pylori and the type of cancer with P > 0.05. And there is a significant association between H.pylori and age more than 5 years with p< 0.05 which is statistically significant among patient groups. The results also showed that there is no significant association between H.pylori and sex among both patient and control groups with P> 0.05.

Immunophenotyping related to cluster of differentiation [CD] markers in patients with atopic dermatitis

Determination of concentrations of cluster of differentiation [CD] markers in patients with atopic dermatitis and comparison with healthy individuals were carried out in this study. It was found that the mean concentrations of positive lymphocytes for AD patients reached 82.2%, 55.7%, 28.7%, and 21.9% for CD3, CD4, Cd8, and GD19, respectively, and those of healthy individuals reached 72.2, 40.3, 18.5, and 13.1 for CD3, CD4, Cd8, and CD19 respectively. We found that the mean values of CDs for AD patients high than those of healthy individuals [69.7%, 75.9%, 94.4% and 68.5%] [P<0.05]

re high than those of healthy individuals [65.7%, 75.9%, 94.4% and 68.5%] [P<0.05]

Bacterial skin colonization in patients with atopic dermatitis/ eczema syndrome

From a total of 286 cases ofAtopic Dermatitis [AD] patients, 94.4% and 86.36% yielded positive cultures of eczematous lesions and healthy area of AD skin. Twenty various bacterial types and a total of 959 and 744 isolates were identified from each of above areas respectively. Staph. aureus was the predominant bacterial agent isolated from 60.48% of eczematous lesions, while Staph. epidermidis was predominantly from 57.34% of healthy areas of AD patients [P< 0.001]. The bacterial numbers ranged from [0.02-92.0]x10[5] cell/cm[2] in eczematous lesions and [0.11-23.0]x 10[3] cell/cm[2] in healthy areas of atopic skin [P< 0.001]
