Question: Is bronchopulmonary dysplasia (BPD) associated with functional/structural abnormalities later in life?
Finding: School-aged children with severe BPD had abnormalities on pulmonary function tests and lung computed tomography despite no subjective respiratory symptoms; however, only prenatal oligohydramnios and prolonged ventilator use were associated with abnormal lung function.
Meaning: Long-term monitoring of preterm infants’ lung health is essential, especially for those with prenatal oligohydramnios or prolonged ventilator use. |

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. MethodsThe 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... |

Purpose B cell-activating factor (BAFF) is a tumor-necrosis factor (TNF) superfamily member best known for its role in the survival and maturation of B cells. BAFF activity is observed in naïve cells as well as in effector/memory T cells. We aimed to explore whether BAFF in sputum is expressed at elevated levels in asthmatic airways and associated with eosinophilic inflammation, pulmonary... |

Thymolipoma is a rare benign tumor of anterior mediastinum. Most patients are asymptomatic with incidental finding of the tumor during a diagnostic workup of other medical problems. We present a case of 13-year-old girl with anterior mediastinal thymolipoma, surgically removed after an incidental diagnosis. |

Pneumonia, which usually requires hospitalization for children, is caused by various pathogens. According to recent surveys, the prevalence of atypical pneumonia caused by Mycoplasma or Chlamydia has increased, especially in preschool children. Also, the evidence has been accumulated that Mycoplasma or Chlamydia infection is associated with asthma including both inception and exacerbation. Therefore, it is important to consider how the... |

Purpose : Asthma is defined as chronic inflammation of the lower small airways, and bronchial hyperreactivity (BHR) is a pathophysiologic feature of asthma. It has been proposed that although there is no direct variable capable of assessing the small airways, a forced expiratory flow of between 25 and 75 percent (FEF25-75) might be considered a more sensitive early marker of... |

Purpose : There has been an increasing amount of literature concerning the association between Mycoplasma pneumoniae and asthma pathogenesis. Interleukin(IL)-6 stimulates the differentiation of monocytes, and can promote Th2 differentiation and simultaneously inhibit Th1 polarization. IL-8 is a potent chemoattractant and, it has been suggested, has a role in asthma pathogenesis. Nitric oxide (NO) synthesized by airway epithelium may be... |
