Abstract

Background The rapid increase in asthma incidence has implicated the importance of environmental influences over genetic influences. Sensitization to perennial indoor allergens has been associated with increased asthma symptoms.Objective To examine the correlation between sensitization to indoor allergens and frequency of asthma exacerbations in children.Methods A cross-sectional study was carried out on asthmatic children aged 6 to 12 years in the Department of Child Health, Udayana University Medical School /Sanglah Hospital, Denpasar. Degree of sensitization was assessed by mean wheal diameter (positive defined as 3 mm greater than negative control) for seven common indoor allergens. Frequency of asthma exacerbation for three consecutive months prior to data collection was retrospectively reviewed.Results Positive skin test results for one or more allergens were found in 84 of 89 (94%) asthmatic children. Higher frequency of asthma exacerbations weakly correlated with the number of allergens with positive sensitization (r=0.284; P=0.007). Mean wheal diameter of each allergen did not correlate to the frequency of asthma exacerbations. In addition, the frequency of asthma exacerbations was independent for parental and sibling atopic history, preceding respiratory infections, use of asthma controllers and passive environmental tobacco smoke exposure.Conclusions Sensitization to common indoor allergens correlates weakly with frequency of asthma exacerbations.

Abstract

Signet ring cell carcinoma (SRCC), a variant of adenocarcinoma, is defined by the presence of more than 50% of tumor cells with prominent intracytoplasmic mucin.1 Primary gastrointestinal malignancies constitute only 1% of pediatric neoplasms and 0.34% take the form of colon carcinoma. It is a very rare disease in persons under 17 years of age, 94% of which is found in children> 9 years of age. [.4 In contrast to adults, approximately50% of colon carcinoma cases in children are the highly malignant mucin'producing adenocarcinoma type.4 The typical signet-ring cell has a large mucin vacuole that fills the cytoplasm and pushes the nuclei to the side, thereby giving the cells their signature histologic appearance.S,6 Carcinoma of the colon during childhood has been associated with familialpolyposis and ulcerative colitis. However, carcinoma arising de novo is the most common type.2,3 Risk factors include a high caloric diet rich in animal fat, sedentary lifestyle, smoking, alcohol consumption, low vegetable fibre consumption, chronic inflammatory bowel disease, ulcerative colitis, Crohn's disease, and polymorphism in key enzymes of injurious compounds.s
