Abstract
HIE is a primary immunodeficiency characterized by recurrent staphylococcal abscesses and markedly elevated serum IgE concentrations. These abcesses involve the skin, lungs, joints, and other sites, and there is a unique tendency to form pneumatoceles following staphylococcal pneumonias. Although, there is as yet no clearly defined immunologic cause for this rare syndrome, but some form of T-Cell defect may be cause, leading to matkedly elevation of IgE and eosinophillia. In this study clinical and immunopathological aspects of HIE syndrome in 11 patients have been evaluated

Abstract
Food allergy is affecting 6-8 percent of infants. Wheat is major source of carbohydrate and protein in the people's nutrition in all worlds and also account for one of six main food allergens in children. The goal of this study is diagnosis of wheat allergic patients and description of its importance for better recognition of this disease.
Materials and Methods: Among children with different symptoms of allergy (dermatologic - Gastro intestinal and respiratory symptoms) referred to Immunology and allergy Department of Markaz Tebbi Kodakan, during one year, 35 cases was suspected to have wheat allergy. Skin prick test and IgE specific with wheat for all of them and open food challenge test with wheat for 11 patients without history of anaphylaxy) were done. The criteria for diagnosis was based on a convincing history of anaphylaxis after ingestion of wheat or the positive result in food challenge with wheat in addition to positive skin prick test ( SPT) or specific IgE ( Eliza) with wheat.
Results: In 35 suspected cases to wheat allergy, SPT in 85/1 percent, specific IgE in 90/3 percent were positive. Food challenge test were done in 11 cases and was positive in 27/2 percent of patients. 24 patients were definitely diagnosed as wheat allergic ones. Anaphylaxis was the predominant clinical feature, accounted for 87 percent of acute symptoms which were repeated for two or more episode in 91 percent of the cases with anaphylaxis. In 50 percent of patients chronic symptoms like asthma and atopic dermatitis were also observed.
Conclusion: The mean age of symptom was compatible with time of onset of complementary foods. Therefore, were proposed exclusive breastfeeding without maternal avoidance and not to be introducing wheat in infant regimen until 12 mouth of age. Anaphylaxis was occurred, repeatedly in these patients which demonstrate, in one part, severity of the reactions in our patients and in other part the probable existence of more cases with milder reactions in whom never been referred to us .

Abstract
Background: Food allergy is one of the most important among other allergic diseases. Although it is less prevalent in adult but in infants it’s prevalence was reported as much as 8 percent. In part, wheat is one of the six main food allergens in infant and in other part there is extensive cross reactivity between the cereals. Therefore the aim of this study is selection of the best food substitute for wheat among other cereals. Materials and Methods: 24 patients with definitive diagnosis of type one hypersensitivity reaction to wheat were entered in this study. Skin prick test and serum specific IgE (Eliza) with 6 members of cereals family (wheat, barley, oat, Rye-Rice & Corn) were performed for them and open food challenge test was also done with three more available of the cereals (corn, Rice, barley) in our food culture and so comparison between allergenicity of wheat flour and wheat bran with skin prick test were done.
Results: The Skin prick tests (SPTs) were positive in 66.7 percent for Barley, 100 percent for wheat bran and 80-100 percent for other cereals. The results of specific IgE for wheat, Barley were positive in 94.5 percent, 68 percent, 39 percent of patients respectively and the results for other cereals were positive in less than 11 percent of cases. The results of food challenge test, for barley were positive in 60 percent of cases and for Rice and Corn were negative in all cases.
Conclusion: In the base of food challenge test as the gold standard test, the best food substitute for wheat sensitive patient between other cereals, were Corn and Rice respectively. It is important to emphasis that will be needed to perform oral food challenge in hospital with complete emergency equipment before introducing any other cereals as food substitute for wheat, specially Barley.

Abstract
Background: Mutations of ELA2, the gene encoding neutrophil elastase (NE) are known to be associated with cyclic neutropenia (CN) and severe congenital neutropenia (SCN). However, high variability of these mutations has been reported. This study was designed to describe the analysis of the ELA2 gene, clinical manifestations and demographic characteristics in patients with CN and SCN.
Methods: A series of 21 patients with CN or SCN were selected, based on SCINR criteria, from the immunology ward of the Pediatric Medicine Center, Tehran, Iran, from March 2004 to August 2005. The ELA2 gene, isolated from blood samples, was analyzed using RT-PCR and automated capillary sequencing. Informed consent was obtained under the tenets of the Helsinki Declaration and the Ethical Committee of the Tehran University of Medical Sciences.
Results: Kostmann's syndrome and CN was diagnosed in three and 18 patients respectively. Of all the patients, one or two mutations were found in 18 cases (85.7%), including all three patients with SCN and 15 of the patients with CN. Exons two and four had the most mutations (eight and seven cases, respectively). Seven patients had double mutations in two distinct exons. Overall, 16 different mutations were found. At the time of presentation, the mean age of patients was 13.4 ±17.6 months, ranging from one month to seven years. Overall, 61.9% of patients had consanguineous parents. The mean absolute neutrophil count was 830.5 ±419.4 (150-2000)/mm3. On average, each patient had been admitted to the hospital 2.2 ±1.6 times. The neutrophil counts of the SCN patients were significantly higher than those of the CN patients. However, there was no significant difference in the neutrophil counts between patients with mutations and those without mutations. All patients with SCN had two or more infectious complications, although the prevalence of infectious or non-infectious complications did not correlate with ELA2 mutations or the neutropenic disorders.
Conclusion: Mutations in ELA2 appear to play an important role in the phatogenetic mechanisms of CN and SCN. Patients with CN had significantly higher neutrophil counts than SCN patients with CN. Although it possible for the gene encoding neutrophil elastase to have more than one mutation in distinct exons, we found no association between the mutations in ELA2 and their complications in CN and SCN patients.
