BACKGROUND Present guidelines for the diagnosis of idiopathic pulmonary fibrosis require histological confirmation of surgical lung biopsy samples when high-resolution CT images are not definitive for usual interstitial pneumonia. We aimed to assess the predictive value of high-resolution CT in a cohort of patients with suspected idiopathic pulmonary fibrosis from a previous randomised trial. ...

OBJECTIVE Interstitial lung disease associated with gefitinib is a critical adverse reaction. When geftinib was administered to EGFR-unknown patients, the interstitial lung disease incidence rate was approximately 3-4% in Japan, and usually occurs during the first 4 weeks of treatment. However, it has not been fully investigated in EGFR-mutated patients. METHODS We collected clinical records ...

Interstitial pneumonias have recently been associated with mutations in the gene encoding surfactant protein C (SFTPC). In particular, SFTPC mutations have been reported in a number of familial forms of pulmonary fibrosis and in infants with interstitial lung diseases. The present study searched for SFTPC mutations in adult patients with sporadic idiopathic interstitial pneumonia. In total, 35 ...

A histologic feature of usual interstitial pneumonia is the presence of fibroblastic foci. As some patients with usual interstitial pneumonia and an underlying collagen vascular disease have a better prognosis, we hypothesized that they would have fewer fibroblastic foci. Pathologists reviewed surgical lung biopsies from 108 patients with usual interstitial pneumonia (nine with collagen vascula...

OBJECTIVE The objective of this study was to determine whether the various chronic cystic lung diseases can be differentiated on the basis of the pattern and distribution of abnormalities on high-resolution CT. MATERIALS AND METHODS High-resolution CT scans in 92 patients with chronic cystic lung diseases (18 with pulmonary Langerhans cell histiocytosis, 18 with pulmonary lymphangioleiomyomat...

OBJECTIVES Surgical lung biopsy (SLB) by videothoracoscopy for diffuse interstitial lung diseases is recommended for detailed diagnosis. Because substantial mortality and morbidity are associated with this procedure, its safety and diagnostic yield should be validated. METHODS Sixty-four patients with diffuse interstitial lung disease who received SLB by videothoracoscopy between 2007 and 201...

OBJECTIVE We retrospectively investigated the clinical features of pulmonary aspergillosis associated with interstitial pneumonia. METHODS We reviewed the medical records of all patients treated for interstitial pneumonia with or without pulmonary aspergillosis at our institution between April 2006 and August 2012 and evaluated the clinical features as well as risk and prognostic factors for ...

The changes in plasma glucose concentration and in interstitial glucose concentration, determined with a miniaturized subcutaneous glucose sensor, were investigated in anesthetized nondiabetic rats. Interstitial glucose was estimated through two different calibration procedures. First, after a glucose load, the magnitude of the increase in interstitial glucose, estimated through a one-point cal...

OBJECTIVE To examine the significant "placebo effect" in a randomized, double-blind, placebo-controlled interstitial cystitis/bladder pain syndrome trial. Randomized clinical trials are the reference standard for therapeutic impact assessment. However, proving efficacy of treatments for interstitial cystitis/bladder pain syndrome with rigorous placebo-controlled trials is difficult due to a sig...
