A case of low back pain syndrome was diagnosed due to spinal metastasis with unknown primary origin. During anesthesia for surgical stabilization, unexpected airway obstruction occurred after endotracheal intubation. Fiber-optic bronchoscopic examination showed narrowing of the trachea and main bronchi caused by extrinsic compression. ⋯ Airway obstruction was relieved thereafter. The extrinsic lesion was diagnosed as mediastinal lung cancer. The mechanism and management of this airway compromise caused by mediastinal tumor is discussed.

Severe community-acquired pneumonia (CAP) is associated with high mortality. The choice of antibiotics should be guided by the distribution of bacterial pathogens. The purpose of this study was to analyze the causative bacteria and outcomes of patients with severe CAP in a medical intensive care unit (MICU) in Taiwan. The results may provide a basis of guidance for future empirical antibiotic treatments. ⋯ Gram-negative bacilli were the most-common causative pathogens among patients with severe CAP requiring mechanical ventilation. Antipseudomonal antibiotics or a carbapenem should be considered to cover Pseudomonas species, extended-spectrum beta-lactamase-producing strains, and Acinetobacter species. If the isolated bacteria are gram-positive, care should be taken to cover the possibility of ORSA. Old age and higher APACHE II scores were associated with higher mortality.
