Question: Is physician-diagnosed current asthma in preschool children associated with the asthma predictive index, atopic sensitization, or pulmonary function test?
Finding: Physician-diagnosed current asthma in preschool children was associated with the asthma predictive index, but not with spirometry, methacholine provocation test, fractional expiratory nitric oxide level, and atopic sensitization.
Meaning: Physician-diagnosed asthma in preschool children may be different from classic atopic asthma in school children or adolescents.

Purpose

Previous studies suggest that the concentration of 25-hydroxyvitamin D [25(OH)D] in cord blood may show an inverse association with respiratory tract infections (RTI) during childhood. The aim of the present study was to examine the influence of 25(OH)D concentrations in cord blood on infant RTI in a Korean birth cohort.

Methods

The levels of 25(OH)D in cord blood obtained from 525 Korean...

Many patients assume that allergic reactions against foods are responsible for triggering or worsening their allergic symptoms. Therefore, it is important to identify patients who would benefit from an elimination diet, while avoiding unnecessary dietary restrictions. The diagnosis of food allergy depends on the thorough review of the patients's medical history, results of supplemented trials of dietary elimination, and in...

Human rhinoviruses and asthma in children
Woo Kyung Kim
Clin Exp Pediatr. 2010;53(2):129-135.   Published online February 15, 2010
Human rhinoviruses (HRVs) is a nonenveloped, single stranded RNA virus belonging to the family Picornavirudae. Transmission by direct contact such as hand-to-hand, hand-to-nose, and hand-to-eye has been readily demonstrated in experimental settings. HRV are the most frequent causes of common cold infection, however, they are also known to replicate in the lower respiratory tract and associated with more severe respiratory...

We evaluated the epidemic and clinical features of acute lower respiratory tract infections in children by influenza virus. Methods : From Feb., 1995 to July, 1997, influenza virus isolations and clinical review were performed on hospitalized children with acute lower respiratory tract infections at...
