The Clinical Significance of Interstitial Pneumonia with Autoimmune Features in Cryptogenic Organizing Pneumonia: A Prospective Multicenter Observational Study.

There are cases of idiopathic interstitial pneumonias (IIPs) that do not meet the diagnostic criteria for connective tissue disease but have clinical features suggestive of autoimmune process. Interstitial pneumonia with autoimmune features (IPAF) was recently proposed as a research concept for these patients. Although several prospective studies on IPAF have been conducted, its clinical significance in cryptogenic organizing pneumonia (COP) remains unclear.

An immunocompetent case of chronic pulmonary aspergillosis caused by Aspergillusviridinutans.

We encountered an extremely rare immunocompetent case of chronic pulmonary aspergillosis (CPA) caused by Aspergillus viridinutans. A 74-year-old woman was admitted with fever and hemoptysis. Chest computed tomography revealed a nodule in the left upper lobe.

Acute Hemorrhagic Rectal Ulcer Complicated by Cytomegalovirus Enteritis following Steroid Pulse Therapy for Acute Exacerbation of Interstitial Pneumonia.

We herein report a rare case of acute hemorrhagic rectal ulcer (AHRU) complicated by cytomegalovirus enteritis following steroid pulse therapy for interstitial pneumonia. An 86-year-old woman underwent steroid pulse therapy for interstitial pneumonia. She was bedridden with dyspnea and suddenly developed melena.

Dramatic improvement in innominate artery compression syndrome with only postural changes in a bedridden elderly patient.

We present the case of a bedridden elderly patient who demonstrated dramatic improvement in innominate artery compression syndrome with postural changes alone. A 94-year-old woman presented with dyspnea. Physical findings revealed stridor in the right-sided decubitus position.

A case of nonmucinous pulmonary micropapillary adenocarcinoma mimicking pulmonary tuberculosis.

We report a rare case of nonmucinous pulmonary micropapillary adenocarcinoma mimicking pulmonary tuberculosis. A 68-year-old woman was hospitalized with hemoptysis. Her computed tomography revealed cavities and tree-in-bud appearance similar to the extensive form of pulmonary tuberculosis.

Successful Treatment of Antifungal Combination Therapy with Inhaled Liposomal Amphotericin B and Oral Voriconazole for Intractable Chronic Progressive Pulmonary Aspergillosis.

We experienced a case of the successful treatment of intractable pulmonary aspergillosis with inhaled liposomal amphotericin B (L-AMB) and oral voriconazole (VRCZ). A 52-year-old man was admitted to our hospital with a fever. Chest computed tomography (CT) revealed an infiltrative shadow.

Nintedanib can be used safely and effectively for idiopathic pulmonary fibrosis with predicted forced vital capacity ≤ 50%: A multi-center retrospective analysis.

Background: Nintedanib is a multi-kinase inhibitor approved for idiopathic pulmonary fibrosis (IPF); however, its efficacy and safety for patients with IPF and restricted pulmonary function remain unclear. Therefore, the objective of this study was to determine the efficacy and safety of nintedanib for patients with IPF and forced vital capacity (FVC) ≤ 50%.

Methods: This was a multi-center retrospective study performed by the Okayama Respiratory Disease Study Group.

Usefulness of a selective neutrophil elastase inhibitor, sivelestat, in acute lung injury patients with sepsis.

Background: Neutrophil elastase plays a crucial role in the development of acute lung injury (ALI) in patients with systemic inflammatory response syndrome (SIRS). The clinical efficacy of the neutrophil elastase inhibitor, sivelestat, for patients with ALI associated with SIRS has not been convincingly demonstrated. The aim of this study was to determine if there are clinical features of patients with this condition that affect the efficacy of sivelestat.

Cavitary pulmonary involvement of diffuse large B-cell lymphoma transformed from extra nodal marginal zone B-cell lymphoma MALT type.

We describe a case of pulmonary diffuse large B-cell lymphoma (DLBCL), which was thought to arise from extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma). A 68-year-old woman presented with a 2-month history of cough and bloody sputum. The chest X-ray and computed tomography revealed a mass with cavitation in the right lower lobe.

Variant angina pectoris associated with FOLFOX4 therapy.

The patient was a 71-year-old man who underwent a right hemicolectomy for ascending colon cancer (pT3, pN1, pM0) and who opted not to receive adjuvant chemotherapy. Eight months later, multiple liver metastases occurred. He therefore received FOLFOX4 (5-fluorouracil/leucovorin and 85 mg/m(2) oxaliplatin) therapy, up to a total of 5 courses, and showed a partial response.

Interstitial lung disease associated with gemcitabine treatment in patients with non-small-cell lung cancer and pancreatic cancer.

Purpose: Although there are several reports concerning gemcitabine-induced interstitial lung disease (ILD), the risk factors for ILD are not well known. In addition, data comparing the incidence and pattern of ILD associated with gemcitabine treatment in patients with non-small-cell lung cancer (NSCLC) versus those with pancreatic cancer are scarce.

Methods: We reviewed clinical records of 118 patients treated with gemcitabine between November 2004 and November 2010.

An oral fluoropyrimidine agent S-1 induced interstitial lung disease: A case report.

A 66-year-old Japanese man with pancreatic cancer received eleven courses of gemcitabine monotherapy. The tumor responded to gemcitabine until metastatic liver tumors progressed. Subsequently, he was treated with S-1, an oral fluoropyrimidine anticancer agent, as salvage chemotherapy.

Synchronous double primary lung cancers with different response to pemetrexed.

We describe the case of a 74-year-old male patient with synchronous double primary lung cancers: adenocarcinoma in the right lower lobe and squamous cell carcinoma in the left upper lobe (LUL). These tumors were difficult to differentiate radiographically from a single metastatic primary cancer, but their eventual diagnoses were triggered by their responses to chemotherapy, which included pemetrexed. After two courses of chemotherapy with pemetrexed and carboplatin, the right lower lobe mass had partially resolved; however, the LUL mass had increased.

A case of pulmonary sclerosing hemangioma surrounded by giant cystic change on high-resolution computed tomography.

Pulmonary sclerosing hemangioma is a rare benign neoplasm, usually presenting as a well-defined round or oval mass. We report a case of pulmonary sclerosing hemangioma surrounded by an unusual giant cystic change on high-resolution computed tomography, which led to the suspicion of this tumor.

Centrally located squamous cell carcinoma of the lung mimicking endobronchial tuberculosis.

Here we report a case of centrally located squamous cell carcinoma of the lung mimicking endobronchial tuberculosis. On the basis of the white light bronchoscopic (WLB) findings, bronchial tuberculosis was initially suspected. But transbronchial biopsy of the lesion revealed squamous cell carcinoma.
