BACKGROUND Pulmonary emphysema is characterized by alveolar destruction and persistent inflammation of the airways. Although IL-17A contributes to many chronic inflammatory diseases, it's role in the inflammatory response of elastase-induced emphysema remains unclear. METHODS In a model of elastase-induced pulmonary emphysema we examined the response of(More)
Obstructive jaundice sometimes may develop in association with advanced small-cell lung cancer (SCLC); however, SCLC initially presenting with obstructive jaundice is rare. This report presents the cases of two SCLC patients with obstructive jaundice at the initial diagnosis. A 64-year-old male presented with obstructive jaundice due to a tumor at the head(More)
The receptor for advanced glycation end-products (RAGE) is a multiligand receptor that belongs to the immunoglobulin superfamily. RAGE is reported to be involved in various inflammatory disorders; however, studies that address the role of RAGE in allergic airway disease are inconclusive. RAGE-sufficient (RAGE+/+) and RAGE-deficient (RAGE-/-) mice were(More)
Pure red cell aplasia (PRCA) rarely occurs in non-thymic lymphoproliferative disorders. The present article describes a patient with non-Hodgkin's lymphoma (follicular, mixed type), who concurrently developed PRCA and warm type autoimmune hemolytic anemia during the clinical course. The PRCA and hemolytic anemia were successfully treated with prednisolone(More)
Congenital diaphragmatic hernia (CDH) is associated with a variety of cardiac anomalies. However, its association with hypoplastic left heart syndrome (HLHS) is rare. We treated a female newborn with CDH, HLHS, and omphalocele. The operation for omphalocele and the diaphragmatic defect was successful, although the patient died of cardiac failure after(More)
Mediastinal lymph node carcinoma of unknown primary site is rare and may have a better prognosis if extensive treatment is performed. Case, A 69-year-old-male presented with a persistent cough. Chest computed tomography (CT) demonstrated a large tumor 9.5 × 8.2 cm, in the mediastinum, compressing the right main bronchus, the right pulmonary artery, and the(More)
The incidence of overlapping bronchial asthma and chronic obstructive pulmonary disease has increased in recent years. Cysteinyl leukotrienes (CysLTs) play an important role in asthma, and the type 1 CysLT receptor (CysLT1R) is expressed by many inflammatory cells. We evaluated the effect of montelukast, a CysLT1R antagonist, on mouse models of asthma,(More)
Heerfordt's syndrome is a rare manifestation of sarcoidosis and is defined as a combination of facial palsy, parotid swelling, and uveitis, associated with a low-grade fever. We report a case of Heerfordt's syndrome presenting with a high fever and increased serum tumor necrosis factor alpha (TNF-α) levels. The patient had facial palsy, parotid swelling,(More)
Dental infection can be an important source for septic pulmonary embolism (SPE), but only a few cases of SPE accompanying dental infection have been reported. The aim of this study was to characterize the clinical features of SPE induced by dental infection. Patients who fulfilled the diagnostic criteria described in the text were recruited in a(More)
We recently reported that IL-17A plays a critical role in the development of porcine pancreatic elastase (PPE)-induced emphysema. The proliferation of T-helper type 17 (Th17) cells was induced by IL-23. To determine the contribution of IL-23 to the development of pulmonary emphysema, a mouse model of PPE-induced emphysema was used in which responses of(More)
