A study of TPA, CEA and IL-2R serum levels was conducted in patients untreated with various histological types of bronchial carcinoma. A total of 43 subjects were evaluated. We have observed a significant correlation between serum levels and stage of the disease for both CEA and TPA markers, whereas for IL-2R an increase was shown for the all patients not correlated with stage.

The presence of dynamic hyperinflation and intrinsic PEEP is a common and yet too often unrecognized occurrence in patients with airway obstruction both in stable state and during acute exacerbations. Intrinsic PEEP may represent an important load on the inspiratory muscles which are operating at a mechanical disadvantage due to hyperinflation. ⋯ The presence of intrinsic PEEP also has other important clinical ramifications. Prompt recognition of intrinsic PEEP will allow for proper measurement and interpretation of a variety of cardiopulmonary parameters and improved clinical decision making and management of these critically ill patients.
