Measles, mumps, rubella and varicella are diseases that are tracked by the World Health Organization (WHO) as common and serious vaccine-preventable diseases. Aim of the Work: To evaluate the immune status and susceptibility against measles, mumps, rubella, and varicella in primary school children and to study the effects of some sociodemographic factors on the seroprevalence. Subjects and methods: This is a cross-sectional study conducted on 180 children. All children included in this study were subjected to thorough history taking and laboratory investigations; to measure serum levels of specific measles, rubella, mumps and varicella immunoglobulins (IgG) Results: (88.9%) of the surveyed children were seropositive to measles, (77.8%) to mumps, (86.7%) to rubella and (38.9%) to varicella. Seropositivity was higher in males than in females for measles (57.7%), mumps (60.7%), rubella (62.2%) and varicella (68.6%) with significant difference for measles. Younger age groups were less seropositive than older age groups for measles (32.5% vs 35%), mumps (34.4 % vs 37.9%), rubella (30.8 % vs 39.7 %) and for varicella (21.4%) vs 48.6%). The highest level of seronegativity was seen with regard to varicella specific antibodies (61.1%). Conclusion and recommendations: There is an urgent need for a planned program with different strategies to prevent and control these diseases .
Background: A prevalence of hepatitis C virus (HCV) infection is relatively low in children as it was 3% and 9% in the upper and lower Egypt areas, respectively. Most chronic hepatitis C patients are asymptomatic and unaware of their disease before diagnosis. Similarly, hepatitis B virus (HBV) is a major cause of chronic liver disease, particularly cirrhosis and hepatocellular carcinoma, though HBV incidence and infection has been markedly reduced after mass vaccination programs. Objectives: To identify the prevalence and risk factors of asymptomatic HCV infection and evaluate response of hepatitis B vaccination among Egyptian children. Materials and Methods: Six hundred children (6-17 years) were screened for HCV antibodies (HCV Ab) and hepatitis B surface antibody concentration (HBsAb) was quantitated by enzyme-linked immunosorbent assay. HCV Ab-seropositive was tested for HCV ribonucleic acid by real-time-polymerase chain reaction, complete blood count, and liver function tests. Results: 4.7% were diagnosed as HCV Ab-seropositive and 58.5 % as HBsAb-seroprotective (HBsAb ≥10 mIU/ml). History of exposure to blood transfusion, frequent intravenous injection, history of prior hospitalization and blood exposure were significantly more likely to be among HCV seropositive. Blood transfusion was considered the most predictable risk factor for HCV infection. There was a significant decrease in HBsAb concentration with increasing age. Conclusion: Booster dose of hepatitis B vaccine should be considered to enhance immune protection of the vaccine especially in our endemic area.

The combination of patent ductus arteriosus, valvular pulmonary stenosis and/or peripheral pulmonary stenosis is very rare. We examined 23 children with this entity. In 9 children there were findings suggestive of rubella syndrome. 17 of the 23 children were born predominantly between October and March. Most of them showed low birth weights. Regarding the cardiac involvement there was no difference between the children with signs of rubella syndrome and those without noncardiac manifestations. In many children the symptoms of the patent ductus are leading. On evaluation of the noninvasive diagnostic procedures the ECG showed often a right ventricular hypertrophy and the x-ray of the chest showed in most cases a cardiac enlargement. In all patients a heart catheterization was necessary to establish the diagnosis. The review of the literature and the interpretation of our findings seems to suggest that the combination of a patent ductus arteriosus with pulmonary stenosis is a typical manifestation of rubella infection in the heart.
Objective The diagnosis of biliary atresia (BA) can be challenging as its histopathologic features overlap with those of other pediatric cholestatic liver diseases. We aimed to study the diagnostic value of hepatic interferon-c (IFN-c) and CD68 immunostaining in the differentiation of BA from other causes of neonatal cholestasis (NC).Patients and methods Hepatic IFN-c and CD68 immunostaining were investigated in 69 patients divided on the basis of the diagnosis into the BA group (n = 34) and the non-BA group (n = 35). The semiquantitative assessment included estimating the average of positive staining cells among inflammatory infiltrate in portal tracts of liver biopsy. ResultsThe mean hepatic CD68 and IFN-c immunostaining in patients with BA was significantly higher (41.2 ± 9.2 and 39.3 ± 12.6, respectively) than that in the cholestasis group (20.8 ± 15.2 and 21.5 ± 15.7, respectively). The cutoff values were 24 for CD68 and 22 for IFN-c to differentiate between BA and cholestatic patients, with a sensitivity and specificity of 94.18 and 74.30% for CD68 and 89 and 73.14% for IFN-c, respectively.Conclusion Both IFN-c and CD68 immunostaining of the liver had a diagnostic value in differentiation between BA and other NC disorders and might be useful as an additional stain when investigating infants with NC.

Asthma is a chronic ,inflammatory ,respiratory tract disease accompanied by hypersensitivity of airways, recurring wheezing episodes, respiratory distress and coughing. The aim of this study was to estimate vitamin D level and specific IgE level in asthmatic children who were on controller medication and correlated their serum level with asthma control . Our results clarified that The serum vitamin[D] levels were closely related to asthma attacks. As,There were statistically significant positive correlations between serum vitamin D level and asthma control in asthmatic children. There were no significant difference in mean serum vitamin [D] between male and female and according to parent consanguinity while shows significant difference regarding order of sibling. there were no significant difference in mean serum vitamin [D] according to family history of atopy and passive smoking, while shows significant difference regarding family history of asthma, associated allergic condition, day time symptoms, night time awakness, degree of asthma control, recurrent hospital admission , interference with activity and frequency of exacerbation and influenza &pneumococcal vaccination. significant difference in mean serum vitamin [D] according to food born allergen: apple ,banana ,casein ,cow milk ,egg white, peanut while regarding airborne allergen shows nonsignificant difference with ,Der.pteronyssinus, Der.farinae ,Cockroach and Honey bee venom and Aspergillus fumigatus . Common wasp venom , Altearia alternate, Honey bee venum,Birch ,Candida albican ,Dog epith. and cat epithelium demonstrated significant difference. From our results, it would be concluded that there was a significant correlation between vitamin [D] level and asthma control in asthmatic children .
Background Colorectal cancer (CRC) is a foremost global health concern and remains one of the major causes of cancer-related morbidity and mortality. It is the third most common cancer in adults after lung cancer and breast cancer worldwide. The theory that cancer originates from a subpopulation of tumor cells, named cancer stem cells (CSC), they have an important role of CSC in the initiation and maintenance of the tumor, as well as invasion, metastasis, and therapeutic resistance. Among CSC markers, CD44 is the most investigated colorectal CSC markers. This study aims to assess the immunohistochemical expression of CD44 in colorectal adenomas & CRCs. And its relation between immunohistochemical expression of CD44 with tumor differentiation (grading), lympho-vascular invasion, perineural invasion, desmoplasia and TNM stage.Methods this is a retrospective descriptive study that included Sixty paraffin embedded blocks from the pathology laboratory, Suez Canal University Hospital. Paraffin blocks included (14 cases of colorectal carcinoma and 18 cases of colorectal adenoma). paraffin blocks reviewed for clinicopathological prognostic factors and stained by CD44, monoclonal antibodies by immunohistochemical method.Results The CD44 protein was overexpressed in 80% of CRC, while was positive (44.4%) in adenoma this difference was statistically.Conclusions CD 44 is highly expressed in large number of CRC (80 of tumors). It is also significantly more expressed in CRC than in adenomas, suggesting a role of CD 44 in CRC tumorigenesis and progression of adenomas into carcinomas. Our study also associated CD 44 overexpression with both late TNM stage and lympho-vascular invasion.
