Background & Objective: Atopic diseases are one of the most common chronic conditions in children. A population based matched study was conducted to estimate the prevalence of atopic diseases and this study used to identify its correlations in primary school children aged 6-12 years in Shiraz (Southern Iran). Materials & Methods: This case-control study was carried out in 2228 primary school children. The children were selected using 2-stage random sampling from the 4 educational distrincts of for each child. The consultant physician examined the children with positive result. After diagnosis of eczema, utricaria and allergic rhinitis control groups were selected by using matching method (Age, sex, school). The correlations of atopic diseases were determined by conditional logestic regression. Results: The most important results were as follow: Prevalence of diagnosed allergic rhinitis, utricaria and eczema in primary school children estimated in order 5.2% (Boys: 5.2% & girls: 5.12%), 3.6% (Boys: 3.57% & girls: 3.7%) and 1.6% (Boys: 1.53% & girls: 1.7%). There was no significant association between atopic diseases and birth order, social class, parent’s education, parent’s smoking and period of breast-feeding. An increased risk of childhood atopic diseases were associated with familiar history of allergic rhinitis (P<0.05), familiar history of utricaria (P<0.05) and familiar history of eczema (P<0.05). Conclusion: Our study confirmed that familiar atopic diseases were significant predictors of childhood allergic rhinitis, utricaria and eczema among school children in Shiraz.

Background and Objective: Cardioembolic stroke account for one-fifth of ischemic stroke and atrial fibrillation is the most common underlying cause. Taking an oral anticoagulation (Warfarin) is an effective way of preventing ischemic stroke but bleeding complication is common. This study was carried out to evaluate the validation of HASBLED score in prediction of hemorrhagic complications in patients with brain ischemia and atrial fibrillation under warfarin therapy. Methods: In this cohort study 112 patients with non-valvular atrial fibrillation in term of major and minor bleeding complications were followed to the predictive value of HASBLED criteria for one year. Major bleeding complications defined as intracranial bleeding, bleeding leading to hospitalization, drop of hemoglubin of more than 2gr/dl or requiring transfusion. HASBLED criteria were defined as hypertension, abnormality in liver and renal function tests, history of stroke, history of bleeding, large fluctuations in coagulation tests results, age more than 65 years and an Anti-platelet and non steroidal anti-inflammatory drugs and alcohol use one point is awarded to each of the aboves. Results: During one year follow up, 10 (9.1%) of patients had major bleeding and 28 (25%) patients had minor bleeding. The risk of major bleeding was significantly related with a history of minor bleeding and HASBLED scores (P<0.05). The risk of minor bleeding was significantly related with warfarin toxicity and high INR (P<0.05). HASBLED score>3 was associated with the likelihood of major bleeding in future. Conclusion: Patients with HASBLED score>3 should be causious in initial stage of taking oral anticoagulant.
