A case report and literature review of nontuberculous mycobacterial disease caused by Mycolicibacterkumamotonensis.

Herein, we report a rare case of pulmonary nontuberculous mycobacterial (NTM) infection caused by Mycolicibacter kumamotonensis in a 73-year-old man successfully treated with clarithromycin, rifampicin, and ethambutol. Seven cases of NTM disease caused by M. kumamotonensis have been previously described, with characteristics differing from those of more common NTM diseases.

Radiological and histopathological features and treatment response by subtypes of interstitial pneumonia with autoimmune features: A prospective, multicentre cohort study.

Background: Patients with idiopathic interstitial pneumonia (IIP) have a favourable prognosis when they have interstitial pneumonia with autoimmune features (IPAF). However, precise IPAF-related findings from high-resolution computed tomography (HRCT) and lung histopathological specimens and the treatment response have not been fully determined. Therefore, this study was conducted to evaluate the relationship between findings on HRCT or lung histopathological specimens and the progression of interstitial pneumonia in patients with IPAF.

Prospective nationwide multicentre cohort study of the clinical significance of autoimmune features in idiopathic interstitial pneumonias.

Background: Some patients with idiopathic interstitial pneumonia (IIP) show autoimmune features. Interstitial pneumonia with autoimmune features (IPAF) was recently proposed as a research concept in these patients. However, retrospective studies reported conflicting results of its prognosis.

Primary malignant melanoma of the trachea: A case report.

Primary cancer of the trachea is rare and accounts for only 0.1-0.4% of all newly diagnosed respiratory tract cancers, worldwide.

[Acute respiratory failure due to pneumocystis pneumonia successfully treated with combined use of sivelestat sodium hydrate].

A 22-year-old man was admitted to our hospital with fever, cough and dyspnea. His chest radiograph showed diffuse ground-glass attenuation in both lung fields. Arterial blood gas analysis showed hypoxemia (PaO2 28.

[Two cases of acute respiratory failure due to idiopathic interstitial pneumonia successfully treated with sivelestat sodium hydrate and steroid therapy].

We encountered two patients with clinically diagnosed idiopathic interstitial pneumonia with acute respiratory distress syndrome (ARDS). Both patients required mechanical ventilation within 24 hours after admission. We managed these patients using lower tidal volume ventilation (tidal volume: 5-6 ml/kg), antibiotics, sivelestat sodium hydrate and steroid pulse therapy followed by oral prednisolone therapy.

Chromosomal numerical abnormalities in early stage lung adenocarcinoma.

Chromosomal numerical abnormalities (CNA) are ubiquitous in human cancers. However, the question of when a CNA occurs in the course of tumor generation and progression, is controversial. Recent radiological scrutiny has enabled the identification of small peripheral lesions in the lung.

[Hypersensitivity pneumonitis induced by Aspergillus niger--a case report].

A 52-year-old woman was hospitalized because of severe cough in August 1994. She had engaged in culturing roses in greenhouses since 1968, and had developed a cough during the summer of 1990. Chest radiography showed diffuse ground-glass opacity in both lung fields, and she suffered from hypoxemia (PaO2 = 45.
