EGFR-mutant lung adenocarcinoma associated with antisynthetase syndrome successfully treated with osimertinib.

Here, we report a rare case involving a 66-year-old man with epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma and antisynthetase syndrome (ASS) treated with osimertinib. The patient presented with respiratory failure and bilateral pulmonary opacities; he was diagnosed with ASS accompanied by interstitial lung disease (ILD), consistent with paraneoplastic syndrome. After steroid pulse therapy, osimertinib was administered for lung adenocarcinoma without ILD exacerbation.

The therapeutic effects of bronchial thermoplasty evaluated by cardiopulmonary exercise testing : a case series.

Bronchial thermoplasty (BT) had been reported to improve the symptoms of severe asthma. However, the exertional responses of BT based on the mechanisms have not been elucidated. A 57-year-old man and a 60-year-old woman underwent BT due to intractable severe asthma.

Diagnostic Validity of Gastric Aspirate Culture in Nontuberculous Mycobacterial Pulmonary Disease.

Although gastric aspirate culture is used for diagnosing pulmonary tuberculosis, its usefulness in diagnosing pulmonary infections of nontuberculous mycobacteria (NTM) is unknown. To investigate the diagnostic validity of gastric aspirate culture for acid-fast bacilli in NTM pulmonary disease (NTM-PD). Gastric aspirates were collected from patients with suspected NTM-PD at the Osaka Toneyama Medical Center between December 2006 and February 2018.

Acute lung injury after plasma exchange in a patient with anti-MDA5 antibody-positive, rapidly progressive, interstitial lung disease：A case report.

The presence of anti-melanoma differentiation-associated gene 5 antibody (anti-MDA5 Ab) is closely associated with rapidly progressive interstitial lung disease (RP-ILD) in patients with clinically amyopathic dermatomyositis. Despite intensive immunosuppressive therapies, some of these patients still have a poor prognosis with few treatment options. Although removal of pathogenic autoantibodies and cytokines by plasma exchange (PE) could be a treatment option, its safety and efficacy have never been determined.
