Efficacy and safety of lascufloxacin for nursing- and healthcare-associated pneumonia: A single-arm, open-label clinical trial.

Background: Nursing- and healthcare-associated pneumonia (NHCAP) constitutes most of the pneumonia in elderly patients including aspiration pneumonia in Japan. Lascufloxacin (LSFX) possesses broad antibacterial activity against respiratory pathogens, such as Streptococcus spp. And anaerobes inside the oral cavity.

A high α1-antitrypsin/interleukin-10 ratio predicts bacterial pneumonia in adults with community-acquired pneumonia: a prospective cohort study.

Background: Current microbiological tests fail to identify the causative microorganism in more than half of all pneumonia cases. We explored biomarkers that could be used for differentiating between bacterial and viral pneumonia in patients with community-acquired pneumonia (CAP).

Methods: In this prospective cohort study conducted in Japan, data obtained from adult patients with bacterial pneumonia, including bacterial and viral coinfections (bacterial pneumonia [BP] group), and purely viral pneumonia (VP group) at diagnosis were analyzed using multivariate logistic regression analysis to identify predictors of bacterial pneumonia.

Interstitial Lung Disease Induced by Pazopanib Treatment.

Although pneumothorax has been reported to be a major pulmonary adverse event in patients treated with pazopanib, a multikinase inhibitor, drug-induced interstitial lung disease (DILD) has not been reported. A 74-year-old Japanese man who received pazopanib for the treatment of femoral leiomyosarcoma and lung metastasis presented with dyspnea and fatigue. He had mild interstitial pneumonia when pazopanib treatment was initiated.

Epidemiology and clinical features of pulmonary nontuberculous mycobacteriosis in Nagasaki, Japan.

Background And Objectives: Recent reports indicate that the incidence of nontuberculous mycobacterial-lung disease (NTM-LD) is increasing. This study aimed to investigate the epidemiology and clinical features of NTM-LD patients in Nagasaki prefecture, Japan to identify the negative prognostic factors for NTM-LD in Japan.

Methods: The medical records of patients newly diagnosed with NTM-LD in eleven hospitals in Nagasaki prefecture between January 2001 and February 2010 were reviewed.

[A case of Paragonimus westermani complicated empyema by Streptococcus pneumoniae].

A 75-year-old man, who had eaten wild boar and deer repeatedly until November 2006, visited our hospital because of a right pleural effusion on chest X-ray films after he bruised a hip in January 2007. A right thoracocentesis revealed exudative pleural effusion with many neutrophils. Ten days after his first visit, a pleural biopsy specimen suggested the existence of parasite eggs.
