A rare case of pulmonary bronchogenic cyst associated with bronchial atresia in the same lobe.

A rare case of 49-year-old woman having pulmonary bronchogenic cyst associated with bronchial atresia in the same lobe was presented. The diagnosis was confirmed by aortography and operation specimen. Three-dimensional reconstructed images of computed tomography clearly demonstrated the defference between mucoid impaction of bronchial trees in the left S9 not communicating with hilar bronchus and the cyst in the left S10 oppressing surrounding vessels.

Role of interleukin-18 and T-helper type 1 cytokines in the development of Mycoplasma pneumoniae pneumonia in adults.

Study Objective: Interleukin (IL)-18 is a proinflammatory cytokine, originally termed interferon (IFN)-gamma-inducing factor, which promotes T-helper type 1 (Th1) cytokine responses. We recently reported that serum IL-18 levels were elevated in children with Mycoplasma pneumoniae pneumonia (MP). In this study, we investigated the contribution of IL-18 to the infection and assessed the Th1 cytokine response to pulmonary involvement in adults.
