Effect of ambulatory oxygen on exertional dyspnea in IPF patients without resting hypoxemia.

Background And Objective: The effects of ambulatory oxygen for idiopathic pulmonary fibrosis (IPF) patients without resting hypoxemia have not been elucidated. The purpose of this study was to assess the effect of ambulatory oxygen on dyspnea in IPF patients without resting hypoxemia but with desaturation on exertion.

Methods: This was a double-blind, placebo-controlled, randomized crossover trial of ambulatory oxygen versus ambulatory air.

Nationwide surveillance of bacterial respiratory pathogens conducted by the Japanese Society of Chemotherapy in 2008: general view of the pathogens' antibacterial susceptibility.

For the purpose of nationwide surveillance of the antimicrobial susceptibility of bacterial respiratory pathogens collected from patients in Japan, the Japanese Society of Chemotherapy conducted a third year of nationwide surveillance during the period from January to April 2008. A total of 1,097 strains were collected from clinical specimens obtained from well-diagnosed adult patients with respiratory tract infections. Susceptibility testing was evaluable with 987 strains (189 Staphylococcus aureus, 211 Streptococcus pneumoniae, 6 Streptococcus pyogenes, 187 Haemophilus influenzae, 106 Moraxella catarrhalis, 126 Klebsiella pneumoniae, and 162 Pseudomonas aeruginosa).

[Intense 18F-fluorodeoxyglucose uptake due to allergic bronchopulmonary aspergillosis].

A 61-year-old woman was admitted with a tumor-like lesion in the middle lobe of the right lung which showed substantial uptake on 18F-fluorodeoxyglucose positron emission tomography (18FDG-PET). The chief complaint was dry cough. On the basis of these findings, lung cancer was first to be ruled out.

[Case of Behçet's disease with frequent recurrence of multiple pulmonary abscess-like opacities].

A 39-year-old woman, who had a history of recurrent oral and genital ulcerations and folliculitis and had had a low-grade fever since December 2003, consulted our hospital on February 5, 2004. Chest radiography and computed tomography (CT) showed multiple pulmonary abscess-like opacities. She was admitted to the Department of Respiratory Medicine and Allergology, Kinki University School of Medicine on February 19, 2004.

[Two cases of AIDS diagnosed by onset of interstitial pneumonia].

Case 1: A 35-year-old man admitted for fever and respiratory failure during several weeks was found in chest computed tomography (CT) to have interstitial pneumonia, and the plasma beta-D-glucan level indicated Pneumocystis jiverocii pneumonia. Psoriasis from second-stage syphilis raised the suspicion of HIV infection. Serum anti-HIV-1 antibody proved positive and CD4-positive lymphocytes in peripheral blood were 18/microL.

[Survival by a young woman with malnutrition due to alcoholism and eating disorders and with acute respiratory distress syndrome due to severe pneumonia who showed increased serum neutrophil elastase activity].

A 30-year-old woman with malnutrition due to alcoholism and eating disorders was found to have acute respiratory distress syndrome (ARDS) and sepsis due to severe Streptococcus pneumoniae pneumonia. S. pneumoniae was detected by an in vitro rapid immunochromatographic assay for S.

[Surviving case of Legionella pneumonia showing a high level of serum KL-6 and complicated with rhabdomyolysis].

A 66-year-old man was admitted to our hospital with pyrexia up to 40 degrees C since one day after taking a public bath. Since multiple infiltrations on the lung were shown by chest radiography, severe pneumonia was diagnosed. Administration of antibiotics meropenem and erythromycin yielded no detected effect.

[A case of a slow-growing, non-mucin-producing bronchioloalveolar carcinoma with a 9-year clinical history before thoracoscopic surgery].

A 73-year-old woman was followed up with high-resolution computed tomography (HRCT) from 2000 through 2002 because an area of ground-glass opacity in area S1 + 2 of the left upper lobe was found on HRCT in August 2000. The opacity was present on ordinary CT scans obtained in 1993, but had not been recognized. Thoracoscopic partial resection of the left lung was performed on October 8, 2002.
