The purpose of this study was to investigate the long-term clinical course of non-specific interstitial pneumonia (NSIP) and to determine which factors are associated with a response to steroid therapy and relapse. Thirty-five patients with pathologically proven NSIP were included. Clinical, radiological, and laboratory data were reviewed retrospectively. The male-to-female ratio was 7:28 (medi...

Familial interstitial lung disease (ILD) is defined as presence of ILD in 2 or more family members. Surfactant protein C (SFTPC) gene mutations are rare, but well-known cause of familial ILD. We reported a 20-year-old male, who was referred for lung transplantation. He was symptomatic at age 3 and underwent surgical lung biopsy at age 6, which revealed a nonspecific interstitial pneumonia (NSIP...

Acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) in lung cancer patients is a critical factor in post-operative mortality. The cause of AE development is unknown and AE may occur in patients without the diagnosis of IPF. We have conducted a retrospective study of consecutive patients who underwent lung cancer surgery since January 2004. Sixty-two patients with fibrous findings in ...

This study was performed to find the rationale for administering steroids to patients with idiopathic interstitial pneumonia (IIP), which was unlikely to be usual interstitial pneumonia (UIP) but was not surgically biopsied. Among IIP patients in the file of the departments, nine patients who met the following criteria were selected for this study ("non-UIP" group): 1) transbronchial lung biops...

was significantly less inHAPE-p than in HAPE-r (1% v 9%, odds ratio 0.10 (95% CI 0.01 to 0.82), p = 0.01). Our findings support the hypothesis that ACE and ET-1 polymorphisms have a role in the susceptibility to HAPE. The findings of the present study and earlier reports on adaptation to high altitude 3 together indicate that ACE and ET-1 genes are significant in high altitude physiology. In co...

Pulmonary vein stenosis (PVS) is a known complication after catheter ablation of arrhythmias. Surprisingly, little information is available on its manifestations in the lung. We describe the case of a 39-year-old woman who presented from an outside hospital with worsening shortness of breath after catheter ablation of pulmonary veins for atrial fibrillation. After an initial diagnosis of pneumo...

Previous studies showed that apoptotic epithelial cells were involved in the pathogenesis of idiopathic pulmonary fibrosis (IPF)/usual interstitial pneumonia (UIP); however, little is known about apoptosis in chronic hypersensitivity pneumonitis (HP). This study was performed to examine whether apoptosis has a role in chronic HP. We performed immunohistochemical studies for p53, p21, Fas, Fas l...

A 63-year-old female diagnosed with relapsed multiple myeloma visited our hospital complaining of a persistent cough. Since July 2006, she had been taking 100 mg thalidomide daily and gradually developed shortness of breath and a persistent dry cough. A chest X-ray and computed tomography showed ground glass opacities in both lungs. An open lung biopsy of the right middle lobe under general ane...
