plastic bronchitis (pb) refers to the presence of inspissated bronchial casts (bc) is uncommon in children.our case presented with subcutaneous emphysema as the dominant manifestation and was suspected to have foreign body in airway, but bronchoscopy revealed a bronchial cast. subcutaneous emphysema as the initial/sole manifestation of plastic bronchitis is very rare in children.

  Introduction: To assess the efficacy and safety of bronchial artery embolization in the treatment of massive hemoptysis.   Materials and Methods: A retrospective study on 46 patients (26 males and 20 females) who were referred to the Razavi Hospital from April 2009 to May 2012 with massive hemoptysis and had bronchial artery embolization procedures. General characteristics of the patients inc...

In asthmatic subjects there is a pronounced diurnal variation in bronchial responsiveness. If this phenomenon is due to variation in factors that control drug delivery, then it should be paralleled by a similar variation in competitive antagonist blockade. In order to study this possibility, we performed the methacholine challenge test and after 45 minutes, administered atropine by inhalat...

Asthma is an inflammatory disorder of the airways and inhaled corticosteroids are the most effective agents in controlling the disease process. The corticosteroid-dose response curve has traditionally been thought of as being flat, i.e. plateaus early, with no further therapeutic response with increasing dose of medication. This is only true for mild asthma and the improvement in airway calibre...

Wheezing lower respiratory illnesses are important causes of morbidity in childhood. Much attention has been fo-cused on the relation between wheezing illness in infancy and subsequent asthma. The study of risk factors for asthma is difficult because of the number of confounding influences contributing to its development, and the difficulty in defining the outcome entity which is a clinical syn...

Background: Asthma is a chronic inflammatory disorder of the airways causing bronchial hyper-responsiveness that characterized by variable and recurring symptoms airflow obstruction. multiple biomarkers measurable in biological fluids. To become useful, these need to be quantifiable reliable systems, reproducible clinical setting, easy obtain cost-effective. bjective: The current study aimed as...
