Low-dose Fluticasone Propionate in Combination With Salmeterol in Patients With Chronic Obstructive Pulmonary Disease.

Inhaled corticosteroids are widely used in the treatment of chronic obstructive pulmonary disease (COPD). However, their use has been questioned for appropriate dose and a possible increased risk of pneumonia. Here, we reviewed patients with COPD who had received fluticasone-salmeterol combination treatment using data from a linked electronic medical record database.

Clinical diagnosis of idiopathic pleuroparenchymal fibroelastosis: A retrospective multicenter study.

Background: Although the accurate diagnosis of pleuroparenchymal fibroelastosis (PPFE) requires pathologic evaluation, this diagnosis is often suggested when the radiologic findings are consistent with typical PPFE and when pulmonary apical cap, which radiologically and pathologically mimics PPFE, can be excluded by confirming disease progression. The aim of this study was to evaluate the validity of the clinical diagnosis of idiopathic PPFE.

Methods: We recruited 44 patients with idiopathic PPFE according to our modified diagnostic criteria: 1) a radiologic PPFE pattern (i.

Persistent impairment on spirometry in chronic eosinophilic pneumonia: A longitudinal observation study (Shizuoka-CEP study).

Background: Chronic eosinophilic pneumonia (CEP) is characterized by the accumulation of eosinophils in the lung with unknown etiology. Although systemic corticosteroid administration leads to dramatic improvement, nearly half the patients with CEP experience relapse and some develop persistent impairment of pulmonary function. However, predictive factors for this persistent impairment have not been determined.

Evaluation of urinary desmosines as a noninvasive diagnostic biomarker in patients with idiopathic pleuroparenchymal fibroelastosis (PPFE).

Background: Pleuroparenchymal fibroelastosis (PPFE) is a rare interstitial pneumonia with upper lobe predominance and fibroelastosis. Although definite diagnosis requires surgical lung biopsy (SLB), SLB is often difficult because of its complications such as refractory pneumothorax.

Objective: To evaluate urinary desmosines (degradation product of mature elastin) as a novel biomarker in patients with PPFE.

Step-down treatment from medium-dosage of budesonide/formoterol in controlled asthma.

Background: The stepping down of asthma treatment can be considered when asthma symptoms have been well controlled with inhaled corticosteroids (ICSs)/long-acting β2 adrenergic agonists (LABAs). However, few data are available comparing the efficacy between two step-down strategies, to reduce ICS/LABA dose or to withdraw LABA continuing ICS, in well-controlled asthmatics.

Methods: This was a prospective multicentre randomized, two-arm, controlled study.

Continuation maintenance therapy with S-1 in chemotherapy-naïve patients with advanced squamous cell lung cancer.

Objectives Maintenance therapy is a standard therapeutic strategy in non-squamous non-small-cell lung cancer. However, there is no consensus regarding the benefit of maintenance therapy for patients with squamous cell lung cancer. We assessed maintenance therapy with S-1, an oral fluoropyrimidine agent, following induction therapy with carboplatin and S-1 in patients with squamous cell lung cancer.

Sequential addition of aprepitant in patients receiving carboplatin-based chemotherapy.

Chemotherapy-induced nausea and vomiting is a challenging issue. Although aprepitant is sometimes used as a therapeutic option in patients receiving moderately emetogenic chemotherapy, the potential benefit of sequential addition of aprepitant to dexamethasone and a 5-hydroxytryptamine-3 (5-HT3) receptor antagonist during the second cycle of carboplatin-based chemotherapy remains unclear. Chemo-naïve patients with advanced non-small cell lung cancer (NSCLC) who received carboplatin-based chemotherapy were treated with doublet antiemetic therapy with dexamethasone and a 5-HT3 receptor antagonist during the first cycle of chemotherapy.

Maintenance therapy with pemetrexed and bevacizumab versus pemetrexed monotherapy after induction therapy with carboplatin, pemetrexed, and bevacizumab in patients with advanced non-squamous non small cell lung cancer.

Objectives: Single agent maintenance therapy is widely accepted for advanced non-squamous non small cell lung cancer (NSCLC). However, there is no consensus on the initial and maintenance phase regimens, and the clinical benefit of adding bevacizumab to cytotoxic drugs in the maintenance phase remains unclear.

Methods: Chemotherapy-naïve patients with non-squamous NSCLC were randomly assigned to maintenance therapy with pemetrexed and bevacizumab or pemetrexed alone, after achieving disease control after four cycles of induction therapy with carboplatin (area under the curve = 6), pemetrexed (500 mg/m(2)), and bevacizumab (15 mg/kg).

Evaluation of palonosetron and dexamethasone with or without aprepitant to prevent carboplatin-induced nausea and vomiting in patients with advanced non-small-cell lung cancer.

Objectives: Although antiemetic management has improved, better control of chemotherapy-induced nausea and vomiting (CINV), particularly during the delayed phase, is needed. The benefit of combination therapy using dexamethasone and the second-generation 5-hydroxytryptamine-3 receptor antagonist palonosetron compared with that of other such receptor antagonists in carboplatin-based chemotherapy is unclear. The effectiveness of adding aprepitant for CINV treatment in moderate emetogenic chemotherapy is also unknown.

Efficacy of short-term prednisolone treatment in patients with chronic eosinophilic pneumonia.

In patients with chronic eosinophilic pneumonia (CEP), dramatic improvements are seen in response to corticosteroid therapy; however, relapse is common after treatment has ceased. The optimal duration of corticosteroid therapy remains unclear. In a randomised, open-label, parallel group study, eligible patients with CEP received oral prednisolone for either 3 months (3-month group) or 6 months (6-month group), followed by 2 years observation.

Quantitative analysis of lung elastic fibers in idiopathic pleuroparenchymal fibroelastosis (IPPFE): comparison of clinical, radiological, and pathological findings with those of idiopathic pulmonary fibrosis (IPF).

Background: The pathological appearance of idiopathic pleuroparenchymal fibroelastosis (IPPFE) with hematoxylin-eosin staining is similar to that of usual interstitial pneumonia (UIP) in patients with idiopathic pulmonary fibrosis (IPF). The amount of elastic fibers (EF) and detailed differences between IPPFE and IPF have not been fully elucidated. The aim of this study was to quantify the EF and identify the differences between IPPFE and IPF.

Aprepitant in patients with advanced non-small-cell lung cancer receiving carboplatin-based chemotherapy.

Objectives: Chemotherapy-induced nausea and vomiting (CINV) is an unanswered problem in cancer therapy. We evaluated the efficacy and safety of triple antiemetic therapy with aprepitant, a 5-hydroxytryptamine-3 (5-HT(3)) receptor antagonist, and dexamethasone in patients with advanced non-small-cell lung cancer (NSCLC) who received carboplatin-based first-line chemotherapy.

Methods: Chemotherapy-naïve patients with NSCLC were enrolled in this randomized phase-II study.

[Phaeomycotic cyst caused by Exophiala xenobiotica in a patient with rheumatoid arthritis and lung cancer].

In black fungal infections, Exophiala species are frequently encountered as causative agents of human mycosis, particularly in immunocompromised patients. Among them, Exophiala jenselmei was previously reported as the most common etiological agent. Advances in molecular taxonomy proved this taxon to be heterogeneous, and led to newly introduced or redefined species.

Maintenance therapy with pemetrexed versus docetaxel after induction therapy with carboplatin and pemetrexed in chemotherapy-naïve patients with advanced non-squamous non-small-cell lung cancer: a randomized, phase II study.

Purpose: The optimal strategy for maintenance chemotherapy is controversial. We evaluated the efficacy and safety of continuation maintenance with pemetrexed and switch maintenance with docetaxel in advanced non-squamous non-small-cell lung cancer (NSCLC).

Methods: Chemotherapy-naïve patients with non-squamous NSCLC were enrolled in this randomized phase II study.

Idiopathic pleuroparenchymal fibroelastosis: consideration of a clinicopathological entity in a series of Japanese patients.

Background: Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a recently reported group of disorders characterized by fibrotic thickening of the pleural and subpleural parenchyma predominantly in the upper lobes. We report five Japanese cases fulfilling the criteria of IPPFE and address whether it should be considered a separate clinicopathologic entity. And this study was an attempt to identify features in common between IPPFE and previously described idiopathic upper lobe fibrosis (IPUF), allowing IPPFE to be considered as a distinct entity in our Japanese series.

Ulcerating bronchitis caused by cytomegalovirus in a patient with polymyositis.

We herein report a case of cytomegalovirus (CMV) bronchitis in a 62-year-old woman with polymyositis. She presented with respiratory symptoms and CMV antigenemia while undergoing immunosuppressive therapy with methotrexate (MTX) and prednisolone (PSL). Bronchoscopy was performed, which revealed an ulceration of the left main bronchus.

Biweekly combination therapy with gemcitabine and carboplatin compared with gemcitabine monotherapy in elderly patients with advanced non-small-cell lung cancer: a randomized, phase-II study.

Introduction: The strategy of chemotherapy in the elderly is controversial. We wanted to evaluate the efficacy and safety of biweekly gemcitabine and low-dose carboplatin combination therapy in elderly patients with advanced non-small-cell lung cancer (NSCLC).

Methods: In this phase-II trial, chemotherapy-naive elderly patients (aged ≥76 years) with NSCLC were randomly treated with biweekly combination therapy with gemcitabine and carboplatin (1000 mg/m(2) gemcitabine and carboplatin at an area under the curve (AUC) of 3 on days 1 and 15, every 4 weeks) or gemcitabine monotherapy (1000 mg/m(2) on days 1, 8 and 15, every 4 weeks).

Effect of switching from salmeterol/fluticasone to formoterol/ budesonide combinations in patients with uncontrolled asthma.

Background: Combination therapy with an inhaled corticosteroid (ICS) and a long-acting β(2)-agonist (LABA) in a single inhaler is the mainstay of asthma management and salmeterol/fluticasone combination (SFC) and fixed-dose formoterol/budesonide combination (FBC) are currently available in Japan; however, there is nothing to choose between the two. The purpose of this study was to clarify the effect of switching from SFC to FBC in patients with asthma not adequately controlled under the former treatment regimen.

Methods: This was a prospective, multicenter, open-label, uncontrolled longitudinal study in 87 adult patients with an Asthma Control Questionnaire, 5-item version (ACQ5) score of greater than 0.

Epithelial-mesenchymal transition induced by transforming growth factor-beta1 in mouse tracheal epithelial cells.

Background And Objective: Epithelial-mesenchymal transition (EMT) is the process by which differentiated epithelial cells undergo a phenotypic transition to mesenchymal cells. This process may occur in certain fibrotic diseases that involve airway remodelling. However, few studies have directly proved the occurrence of EMT in primary cultures of airway epithelial cells.

[Thyroid involvement of sarcoidosis].

A 54-year-old woman was found to have abnormal shadows on her chest radiograph taken on an annual medical examination. The chest radiograph showed multiple nodules in the bilateral middle and lower lung fields accompanied with bilateral hilar lymphadenopathy. A computed tomography of the neck and chest revealed nodules in her right middle lobe and bilateral lower lobes with an enlarged thyroid.

Possible therapeutic effect of direct haemoperfusion with a polymyxin B immobilized fibre column (PMX-DHP) on pulmonary oxygenation in acute exacerbations of interstitial pneumonia.

Background And Objective: Acute exacerbations of interstitial pneumonias (IP) can occasionally occur, and have an extremely poor prognosis. Recently, direct haemoperfusion with a polymyxin B immobilized fibre column (PMX-DHP) was shown to have a beneficial effect in acute exacerbations of IPF. However, little is known about the efficacy of PMX-DHP in acute exacerbations of other IP.

Involvement of the p38 MAPK pathway in IL-13-induced mucous cell metaplasia in mouse tracheal epithelial cells.

Background And Objective: IL-13 has been shown to play a pivotal role in mucous cell metaplasia, which is an important feature of the pathogenesis of asthma. However, the signalling pathways evoked by IL-13 in airway epithelial cells remain unclear. This study investigated the signalling mechanism of IL-13-induced mucous cell metaplasia in primary cultures of mouse tracheal epithelial cells (mTEC).

[An adult case of asymptomatic congenital tracheal stenosis].

A 42-year-old woman was admitted with abnormal chest radiographs. Though interstitial pneumonia associated with dermatomyositis was diagnosed, her chest radiograph also revealed a narrowed trachea about 6 mm in diameter. Bronchoscopy showed that her trachea lacked a membranous posterior segment and O-shaped complete tracheal rings were present throughout the trachea, indicating congenital tracheal stenosis.

[A case with pulmonary epithelioid hemangioendothelioma found on school medical check].

A 15-year-old man was incidentally found to have abnormal shadows in bilateral lungs on a chest X-ray film obtained at a school medical examination, and was referred to our hospital for a close investigation. Several lymph nodes were palpable in his cervical region. Chest X-ray and CT showed multiple and various sized nodules up to 20 mm in diameter in bilateral lung field.

[A case of primary pulmonary MALT lymphoma as a nodular shadow on CT scan, and relapsed with diffuse micronodular shadows after surgical resection at 7 years ago].

A 76-year-old man without symptoms was admitted to our hospital for investigation of an abnormal chest shadow in 1994. His chest radiograph showed a nodular shadow in the lingual lobe. Segmentectomy was performed and the histological diagnosis was MALT (mucosa-associated lymphoid tissue) lymphoma.
