Expectorationof large, branching, bronchial casts, termed plastic bronchitis, is an uncommon condition in children. Asthma or allergy often is the cause of cast production, but in some instances no etiology is found. Five children produced large, obstructing bronchial casts that either were expectorated or were extracted at bronchoscopy. Four of the children had asthma or allergies and the fifth had congenital tricuspid atresia and chronic pericardial and pleural effusions.

The results of this pilot study suggested that (62)Cu-ATSM uptake may be a predictive indicator of tumor response to chemoradiotherapy in patients with locally advanced head and neck cancer.
