Clinical Trial[Prognostic value of acute pulmonary vascular response to oxygen inhalation in patients with chronic obstructive pulmonary disease].
Seventy-two patients with chronic obstructive pulmonary disease (COPD) underwent right heart catheterization when they were clinically stable and the relationship between length of survival and acute pulmonary vascular response to 100% oxygen inhalation was studied. Oxygen inhalation significantly reduced mean pulmonary arterial pressure (PPA), cardiac index (CI), and pulmonary arteriolar resistance (PAR). The percent change in PAR (% delta PAR) was used as an index of the acute pulmonary vascular response to 100% oxygen inhalation. ⋯ However, FEV1 and VC were significantly lower in nonresponders than in responders. The % delta PAR was not significantly related to age, PPA, PAR on air inhalation, FEV1, FEV1%, VC or VC%. We conclude that the pulmonary vascular response to oxygen inhalation (% delta PAR) may be an independent prognostic factor in patients with COPD.

Case Reports[Computed tomographic findings in septic pulmonary emboli secondary to renal abscess].
A 73-year-old woman with diabetes mellitus and hypothyroidism had been well until 4 days before she presented with fever, productive coughing, and general malaise. Dyspnea gradually worsened, and she was admitted to Kobe City General Hospital. She appeared toxic and was in moderate respiratory distress on admission. ⋯ Treatment with antibacterial drugs was effective against the lung lesions but not the renal abscess. A left nephrectomy was done. In the proper clinical setting, characteristic CT features of septic emboli can contribute to early diagnosis of this disease.
