Favorable outcome of pneumonia due to Panton-Valentine leukocidin-producing Staphylococcus aureus associated with hematogenous origin and absence of flu-like illness.

Reported here is what is believed to be the first case of community-acquired pneumonia caused by a Panton-Valentine leukocidin-producing strain of Staphylococcus aureus in Spain. Although lung infections caused by S. aureus strains carrying this powerful leukocidin gene are associated with necrotizing pneumonia and high mortality, the previously healthy 28-year-old male reported here experienced a good clinical course and recovery.

[Bronchiolitis obliterans associated with organizing pneumonia. Clinico-pathological study of 6 cases].

Over the last three years six patients diagnosed of bronchiolitis obliterans with organizing pneumonia were studied. Diagnosis was established by open lung biopsy in 4 and by transbronchial lung biopsy in 2. The initiation of the symptoms was subacute although one patient evolved to respiratory failure requiring mechanical ventilation.
