METHODS We analyzed data on 7,538 children aged 2 to 11 years who participated in the Third National Health and Nutrition Examination Survey to examine the cross-sectional associations of history of ear infections with prevalence of ever-diagnosed asthma and the prevalence of wheezing in the last year in US children. RESULTS History of ear infections was significantly related to the lifetime ...

Results The age average of the babies who were studied was 20,3± 1,5 months. 46,9 % of the babies were girls, 53,1 % were boys. At the beginning of the study 12,5 % of the babies’ serum 25(OH)D3 levels were deficient, 39,1 % of the babies’ were insufficient, 48,4 % of the babies’ were sufficient. The average of the babies’ vitamin D level was 29,8 ±10,8 ng/ml. At the end of study, 29,7 % of the...

PURPOSE OF REVIEW Recurrent wheezing is a common problem in young children. RECENT FINDINGS Approximately 40% of children wheeze in their first year of life. However, only 30% of preschoolers with recurrent wheezing still have asthma at the age of 6 years. Nevertheless, asthma, the most prevalent chronic disease in children, is difficult to diagnose in infants and preschoolers. SUMMARY We r...

INTRODUCTION recurrent wheezing is a common problem during the first years of life, but it is still difficult to identify which of these children may develop asthma in the future. OBJECTIVES To study risk factors of developing asthma in a group of patients with frequent wheezing during the first three years of life. MATERIAL AND METHODS A prospective study was performed of a group of 60 pat...

BACKGROUND Asthma prevalence is increasing worldwide, especially in developing countries. AIM To determine the prevalence of asthma diagnosis and related symptoms in children, its changes during a 6-year period and the influence exerted by socioeconomic status. MATERIALS AND METHODS Cross-sectional study conducted among school children of Santiago. A sample of 4,561 children aged 6-7 and 13...

BACKGROUND The question of the protective effect of breastfeeding on development of asthma has raised substantial interest, but the scientific evidence of the optimal duration of breastfeeding is controversial. METHODS The authors elaborated the optimal duration of breastfeeding with respect to the risk of asthma primarily, and secondarily to the risk of persistent wheezing, cough and phlegm ...

Thirty-four cases of asthma in children referred to outpatient clinics in Newcastle upon Tyne (16 cases) and London (18 cases) were reviewed. In both cities there was evidence of inappropriate diagnosis and treatment by general practitioners. One of the main factors seemed to be doctors' reluctance to use the word "asthma," even when a history of episodic wheezing strongly suggested the diagnos...

This study aimed to measure the prevalence and severity of asthma symptoms and to investigate the association between asthma symptoms and personal, geographic, and socioeconomic variables in 13-14-year-old schoolchildren enrolled in the 7th and 8th grades in Tubarão and Capivari de Baixo, Santa Catarina State, Brazil. This was a cross-sectional study using the ISAAC (International Study of Asth...

A particle filtering (PF) approach is presented for performing sequential geoacoustic inversion of a complex ocean acoustic environment using a moving acoustic source. This approach treats both the environmental parameters [e.g., water column sound speed profile (SSP), water depth, sediment and bottom parameters] at the source location and the source parameters (e.g., source depth, range and sp...

BACKGROUND Asthma, involving 5-10% of global population, has a heterogeneous distribution in the community regardless of age and its prevalence and incidence tend to grow worldwide as reported by many recent epidemiologic surveys. MATERIALS AND METHODS The present study aimed to survey the prevalence of asthma symptoms in Tehran as the first attempt in terms of situation analysis of the disea...
