Clinical benefit of two-times-per-day aclidinium bromide compared with once-a-day tiotropium bromide hydrate in COPD: a multicentre, open-label, randomised study.

Objective: Chronic obstructive pulmonary disease (COPD) is mainly treated pharmaceutically with bronchodilators. The purpose of this study was to evaluate the clinical benefits of two-times-per-day aclidinium bromide (Acli-BID) compared with once-a-day tiotropium bromide hydrate (Tio-QD) in patients with COPD.

Design: This study was a multicentre, open-label, randomised study.

Asthma mortality based on death certificates: A demographic survey in Kagawa, Japan.

Background: We aimed to determine the reasons for the high rate of asthma mortality in Kagawa Prefecture, Japan, by analyzing death certificates.

Methods: We analyzed the death certificates between 2009 and 2011 in a demographic survey. Of 1187 patients with documented disease names suggesting bronchial asthma, analysis was performed on 103 patients in whom the cause of death was classified as asthma based on ICD-10 Codes.

The usefulness of pleural fluid presepsin, C-reactive protein, and procalcitonin in distinguishing different causes of pleural effusions.

Background: We aimed to determine the presepsin concentration in pleural fluid from patients with pleural effusions of different aetiologies and to compare its diagnostic value with that of pleural fluid C-reactive protein (CRP) and procalcitonin (PCT).

Methods: We enrolled 132 patients with pleural effusion who underwent diagnostic evaluation, and we classified them into six categories: empyema, parapneumonic effusion, tuberculous effusion, malignant effusion, paramalignant effusion, and transudate effusion. Additionally, all pleural effusions were categorised as infectious or non-infectious effusions.

Occurrence of bronchioloalveolar cell carcinoma in two brothers: comparison of clinical features and immunohistochemical findings.

It has been suggested that lung cancer sometimes aggregates in families. However, the familial occurrence of bronchioloalveolar carcinoma (BAC) is extremely rare. We present a family in which two brothers had BAC.

Nonspecific interstitial pneumonia/fibrosis completely recovered by adding cyclophosphamide to corticosteroids.

Nonspecific interstitial pneumonia/fibrosis (NSIP) was first described by Katzenstein and Fiorelli in 1994 (Am J Surg Pathol 18: 136-147). Many reports have described that corticosteroids are effective for NSIP. We describe a case of group II idiopathic NSIP in whom cyclophosphamide was administered since the initial response to corticosteroids had been insufficient.

Evaluation of the clonality of multilobar bronchioloalveolar carcinoma of the lung: case report.

A case of multilobar bronchioloalveolar carcinoma (BAC) is reported. To investigate the clonality of BAC, immunohistochemical staining as well as genetic analysis were performed. To investigate point mutations of the p53 gene, we used the polymerase chain reaction and fluorescence-based single strand conformation polymorphism analysis method.
