Prevalence of Common Aeroallergens in Patients with Allergic Rhinitis in Gorgan, North of Iran, Based on Skin Prick Test Reactivity

Background Allergic rhinitis is one of the most common types of rhinitis. Allergen avoidance is the most important way of preventing this disease. The present study is carried out to determine the frequency of common aeroallergens in patients with allergic rhinitis in Gorgan city by skin prick test (SPT) reactivity. Materials and Methods  In this cross-sectional study 270 patients referring to the Asthma and Allergic Center in Gorgan city, Iran, were enrolled. Diagnosis of allergic rhinitis was confirmed by specialist asthma and allergy. A questionnaire containing demographic data and patient’s history was completed. Skin prick test containing standard allergen extracts, histamine, and physiologic serum was performed on patients. The data were analyzed using SPSS software version16.0. Results: In the present study, 270 patients (113 males and 157 females) had perennial allergic rhinitis (PAR), seasonal allergic rhinitis (SAR), and mixed allergic rhinitis (MAR) (n=166, 54, 47, receptivity). Out of these patients, the most common aeroallergens was a house dust mite called Dermatophagoides pteronyssinus (43.7%), other common allergen were: weeds (40.7%), Dermatophagoides farinae (40.4%), grasses (32.5%), beetles (30%), trees (22.5%), and molds (16.3%). There was a significant relationship between prevalence of allergy to grasses and gender (P=0.016), weeds and age (

Mapping 123 million neonatal, infant and child deaths between 2000 and 2017

Since 2000, many countries have achieved considerable success in improving child survival, but localized progress remains unclear. To inform efforts towards United Nations Sustainable Development Goal 3.2—to end preventable child deaths by 2030—we need consistently estimated data at the subnational level regarding child mortality rates and trends. Here we quantified, for the period 2000–2017, the subnational variation in mortality rates and number of deaths of neonates, infants and children under 5 years of age within 99 low- and middle-income countries using a geostatistical survival model. We estimated that 32% of children under 5 in these countries lived in districts that had attained rates of 25 or fewer child deaths per 1,000 live births by 2017, and that 58% of child deaths between 2000 and 2017 in these countries could have been averted in the absence of geographical inequality. This study enables the identification of high-mortality clusters, patterns of progress and geographical inequalities to inform appropriate investments and implementations that will help to improve the health of all populations
