Effects of Home Nursing and Rehabilitation on Daily Life and Outgoing Activities in a Patient With Interstitial Pneumonia Supported by a High-Flow Nasal Cannula: A Case Report.

A high-flow nasal cannula is used as the primary therapy for patients with respiratory failure. Its effectiveness, however, is contingent upon proper patient monitoring by trained healthcare professionals. The case report highlights the benefits of home nursing and rehabilitation in an 81-year-old woman with rheumatoid-related interstitial pneumonia (complicated by drug-induced interstitial pneumonia) who developed respiratory failure.

An effective case of bronchoscopic balloon dilatation for tuberculous bronchial stenosis.

Endobronchial tuberculosis often causes bronchial stenosis. Balloon dilation is a minimally invasive and effective bronchoscopic intervention for bronchial stenosis; however, reports on balloon dilation in older individuals are limited. We present a case of a 77-year-old woman with endobronchial tuberculosis and clarify the efficacy and safety of balloon dilation.

Internal Pancreatic Fistula with Pleural Effusion Showing Elevated Levels of Amylase That Emerged 29 Years after Abdominal Surgery.

A 65-year-old woman presented to a hospital with complaints of dyspnea and lumbar pain. Chest computed tomography (CT) showed left pleural effusion. Thoracentesis showed pleural effusion with elevated levels of amylase.

Role of prostaglandin E in bronchoconstriction-triggered cough response in guinea pigs.

A feature of cough variant asthma is a heightened cough response to bronchoconstriction. The mediators of this response are unknown. This study was designed to elucidate the role of lipid mediators in bronchoconstriction-triggered cough response in an experimental animal model.

Transformation to small-cell lung cancer following treatment with EGFR tyrosine kinase inhibitors in a patient with lung adenocarcinoma.

We report the case of a 52-year-old woman with lung adenocarcinoma treated with EGFR tyrosine kinase inhibitor (TKI) therapy. After disease progression, histological examination of a secondary biopsy specimen revealed small-cell lung cancer (SCLC) that was sensitive to standard SCLC treatment. Tumor markers, including ProGRP and NSE, were elevated.

Effects of pirfenidone on increased cough reflex sensitivity in guinea pigs.

Pirfenidone, an antifibrotic drug with anti-inflammatory and antioxidant effects, delays fibrosis in idiopathic pulmonary fibrosis (IPF). Patients with IPF have a greater cough reflex sensitivity to inhaled capsaicin than healthy people, and cough is an independent predictor of IPF disease progression; however, the effects of pirfenidone on cough reflex sensitivity are unknown. After challenge with an aerosolized antigen in actively sensitized guinea pigs, pirfenidone was administered intraperitoneally, and the cough reflex sensitivity was measured at 48 h after the challenge.

Successful treatment with chemotherapy and corticosteroids of pulmonary Mycobacterium abscessus infection accompanied by pleural effusion.

We describe a 50-year-old woman with rapidly progressive pulmonary Mycobacterium abscessus (M. abscessus) infection accompanied by pleural effusion and organizing pneumonia (OP). CT scan showed consolidation, centrilobular shadows, ground-glass opacity (GGO), and cavities.

Pulmonary manifestations of anti-ARS antibody positive interstitial pneumonia--with or without PM/DM.

Background: Autoantibodies against aminoacyl-tRNA synthetases (ARS) have been found to be highly specific for polymyositis and dermatomyositis (PM/DM) and to correlate strongly with complicating interstitial pneumonia (IP). The aim of the present study was to compare the clinical presentations of anti-ARS antibody-positive IP patients with or without manifestations of PM/DM.

Methods: We retrospectively examined 36 IP patients with anti-ARS antibodies.

Heightened cough response to bronchoconstriction in cough variant asthma.

Background And Objective: The pathophysiology of cough variant asthma (CVA) is poorly understood. We compared bronchoconstriction-triggered cough between CVA patients and normal control (NC) subjects.

Methods: There were two protocols in the study.

Pulmonary T-cell lymphoma with pulmonary arterial hypertension.

We report on a 73-year-old man with systemic lymphadenopathy and chest computed tomography (CT) findings of bilateral diffuse ground-glass opacities and interlobular septal thickening. He also had pulmonary arterial hypertension (PAH). Several lymph node biopsies were attempted, without a definitive diagnosis.

Bronchoconstriction-triggered cough is impaired in typical asthmatics.

Background And Objective: Cough is an essential innate protective behavior, which is experienced by even healthy individuals. The mechanism of cough triggered by bronchoconstriction is not yet clear. The aim of this study was to investigate the relation between bronchoconstriction and cough caused by methacholine (Mch) inhalation in typical asthmatics and normal healthy subjects.

[A case of Churg-Strauss syndrome with methylprednisolone sodium succinate allergy].

A 63-year-old man with a history of therapy for asthma was admitted to a neighborhood hospital for treatment of a lower limb blister, accompanied by edema, pain and systemic fever. Churg-Strauss syndrome was diagnosed based on an increase in peripheral blood eosinophils, positive MPO-ANCA and other findings. He was given an injection of methylprednisolone sodium succinate; however his lower limb pain, fever and peripheral blood eosinophilia worsened.

Bronchodilator effect of deep inspiration and bronchoconstriction-triggered cough.

Background: Cough in the patients with cough variant asthma is triggered by bronchoconstriction, which responds to bronchodilator therapy. Following airway narrowing induced by inhaled methacholine, deep inspiration (DI) causes dilation of the airways in both asthmatic and non-asthmatic subjects. The aim of the present study was to investigate the relationship between bronchodilator effect of DI and bronchoconstriction-triggered cough.

Effects of macrolides on antigen-induced increases in cough reflex sensitivity in guinea pigs.

Background: Macrolides are antibiotics that have anti-inflammatory activities. Hence, they are used for both acute and chronic inflammatory airway diseases. However, the effects of these agents on allergic airway disorders presenting with an isolated chronic cough, such as non-asthmatic eosinophilic bronchitis and eosinophilic tracheobronchitis with cough hypersensitivity (atopic cough), still remain to be elucidated.

Evaluation of airway hyperresponsiveness and exhaled nitric oxide as risk factors for airway remodeling in patients with stable asthma.

Chronic eosinophilic airway inflammation, airflow limitation, and airway hyperresponsiveness (AHR) are distinctive features of bronchial asthma. Exhaled nitric oxide (eNO) is a marker of eosinophilic airway inflammation. Airway remodeling due to chronic airway inflammation results in fixed airway obstruction.

[A case of severe asthma exacerbation complicated with cerebral edema and diffuse multiple cerebral micro-bleeds].

A 36-year-old woman was admitted to the Intensive Care Unit for the treatment of severe asthma exacerbation. Her condition of asthma improved with systemic glucocorticosteroids, inhaled beta2-agonist, intravenous theophylline and inhaled anesthesia (isoflurane) under mechanical ventilation. Her consciousness was disturbed even after terminating isoflurane.

Eosinophilic pneumonia and thoracic metastases as an initial manifestation of prostatic carcinoma.

We herein report an 80-year-old man with prostatic carcinoma who developed eosinophilic pneumonia and intrathoracic metastases. He presented with shortness of breath, cough, and fever as a chief complaint. Chest X-ray and computed tomography showed bilateral pulmonary nodules, intrathoracic lymphadenopathy, and right-sided consolidation.

Sputum eosinophilia, airway hyperresponsiveness and airway narrowing in young adults with former asthma.

Background: 30-80% of outgrown asthma subjects develop symptoms again later in life. We investigated inflammation and function of lower airway in adolescents with former asthma.

Methods: 326 never-smoking young adults (mean age 24.

Hypersensitivity pneumonitis and bronchial asthma attacks caused by environmental fungi.

We report a case of hypersensitivity pneumonitis and asthma attacks caused by environmental fungi in a 75-year-old man. The diagnosis was established by inhalation challenge with Bjerkandera adusta and Aspergillus fumigatus. The patient was admitted for treatment of fever, wheezing, and dyspnea.

Extrinsic allergic alveolitis with eosinophil infiltration induced by 1,1,1,2-tetrafluoroethane (HFC-134a): a case report.

A 22-year-old woman was admitted with symptoms of dyspnea and fever with pulmonary infiltrates noted on her chest X-ray study. She developed these symptoms in the workplace; her job included the removal of body hair using a diode-laser with 1,1,1,2-tetrafluoroethane (HFC134a, an alternative to chlorofluorocarbon) as a coolant. A chest X-ray examination revealed ground-glass opacities in the lower lung fields, and a chest computed tomographic study showed diffuse centrilobular opacities.

Progression of interstitial lung disease upon overlapping of systemic sclerosis with polymyositis.

We describe a 73-year-old woman with systemic sclerosis (SSc)-polymyositis (PM) overlap syndrome, primarily SSc followed by PM. She had suffered from SSc and had interstitial pneumonia (IP), which was stable. Eight years after the initial diagnosis of SSc, proximal muscle weakness, myalgia, and dyspnea on effort developed.

[Asymptomatic pulmonary actinomycosis diagnosed by transbronchial lung biopsy (TBLB)].

A 65-year-old asymptomatic man was admitted to our hospital because a chest abnormal shadow had been pointed out on a medical examination. Our investigation resulted that the consolidation in the left lung had been initially documented in 2002, and had been expanding every year. Bronchofiberscopy showed flare, swelling and stenosis of the left B8, B9 and B10.

Primary pulmonary artery sarcoma detected with a pulmonary infarction.

Primary malignant tumors of the pulmonary arteries occur infrequently. The clinical presentation and diagnostic imaging features of the tumor are usually nonspecific and correct diagnosis is often delayed. In this report, we present a case of pulmonary artery sarcoma.

Randomized phase II trial of OK-432 in patients with malignant pleural effusion due to non-small cell lung cancer.

To determine the optimum dose of OK-432 for intrathoracic administration, a multicenter randomized phase II trial was conducted in patients with malignant pleural effusion due to non-small cell lung cancer. Patients with histologically- or cytologically-proven malignant pleural effusions were randomized to arm A (10 Klinische Einheit (KE) of OK-432) or arm B (1 KE of OK-432). OK-432 was injected intrapleurally over 30 min on days 1 and 3 and the chest tube was clamped for 6 h.
