BACKGROUND Asthma is a heterogeneous condition and differential effects of pet ownership on non-atopic versus atopic asthma have been reported. The aim of this study was to investigate whether pet ownership during pregnancy and early childhood was associated with wheezing from birth to age 7 years and with lung function at age 8 years in a UK population-based birth cohort. METHODS Data from t...
PURPOSE Wheezing following viral lower respiratory tract infections (LRTIs) in children <2 years of age is an important risk factor for the development of asthma later in life; however, not all children with viral LRTIs develop wheezing. This study investigated risk factors for the development of wheezing during viral LRTIs requiring hospitalization. METHODS The study included 142 children <2...
OBJECTIVE Higher maternal intake of vitamin D during pregnancy is associated with a lower risk of wheezing in offspring. The relationship between cord-blood levels of 25-hydroxyvitamin D (25[OH]D) and childhood wheezing is unknown. We hypothesized that cord-blood levels would be inversely associated with risk of respiratory infection, wheezing, and asthma. PATIENTS AND METHODS Cord blood from...
BACKGROUND Past studies reported evidence of associations between air pollution and respiratory symptoms and morbidity for children. Few studies examined associations between air pollution and emergency room (ER) visits for wheezing, and even fewer for gastroenteric illness. We conducted a multicity analysis of the relationship between air pollution and ER visits for wheezing and gastroenteric ...
BACKGROUND The relation of parental smoking to wheezing and asthma occurring after the first year of life was assessed by a systematic quantitative review of case-control and longitudinal studies, complementing earlier reviews of cross sectional surveys and wheezing in early childhood. METHODS Fifty one relevant publications were identified after consideration of 1593 abstracts selected by el...
Asthma is the most common cause of recurrent wheezing, cough and dyspnea in childhood. Delay in diagnosis and lack of appropriate treatment can cause sustained changes which decrease respiratory capacity of children in future. Therefore, identifying the symptoms relating to asthma is the key for timely diagnosis and treatment of this disease. This study was done to investigate asthma incidence ...
The sputum differential eosinophil/neutrophil count was done in 384 patients using Leishman staining. The patients were distributed in four groups: bronchial asthma (197 patients); chronic bronchitis with wheezing (45 patients); chronic bronchitis and/or emphysema without wheezing (73 patients); other pulmonary diseases (64 patients). Eosinophils were present in patients from all groups but mor...
BACKGROUND The elucidation of factors that trigger the development of transient wheezing in early childhood may be an important step toward understanding the pathogenesis of asthma and other allergic diseases later in life. Transient wheezing has been mainly attributed to viral infections, although sensitisation to aeroallergens and food allergens may occur at an early age. In developing countr...
The aim of study was to evaluate various risk in patients who were hospitalized with moderate to severe virus-induced wheezing. Infants hospitalized with virus-induced wheezing were enrolled in the study. Respiratory viruses were detected in nasopharyngeal swab and total IgE levels and skin prick tests were performed in all patients. The mean age of the patients was 11.2±9 months. The most comm...
