We evaluated the clinical features of 32 patients with pulmonary infections caused by methicillin-resistant Staphylococcus aureus (MRSA). Most of the patients were elderly, postoperative, and had severe underlying diseases. Chest radiograph typically showed bilateral and multilobar involvement. ⋯ We also performed an epidemiologic study of MRSA infections by chromosomal DNA analysis using pulsed-field gel electrophoresis. Thirty-two strains were classified into 20 different types by chromosomal DNA pattern, and 5 epidemic strains were observed. These strains were considered to be transmitted among patients by hospital personnel.

Comparative Study
Accuracy of portable chest radiography in the critical care setting. Diagnosis of pneumonia based on quantitative cultures obtained from protected brush catheter.
Sixty-six supine portable chest radiographs done on the day of bronchoscopy in 62 critical care unit patients suspected of having pneumonia were examined in a blinded fashion by two radiologists. Quantitative culture results obtained from protected brush catheter (PBC) specimens were compared with chest radiograph scores. ⋯ The kappa statistic was calculated at 0.27 indicating marginal interobserver reproducibility. We conclude the portable chest radiograph in the critical care setting is not accurate in predicting the presence of pneumonia when the diagnosis is based on quantitative cultures obtained from protected brush catheter specimens.

Dehiscence of the bronchial stump, particularly following pneumonectomy, is one of the most serious complications in lung surgery. Various approaches to this problem have been tried. Two patients with postpneumonectomy bronchopleural fistula were treated successfully by using a pedicle of the greater omentum.

The treatment of lipoid pneumonia, an uncommon chronic lung condition, is generally conservative. We describe a patient with idiopathic lipoid pneumonia who was successfully treated with oral steroids with improvement of chest radiographic abnormalities.
