Inhaled Corticosteroid-Containing Regimens Reduce Hospitalizations and Healthcare Costs among Elderly Asthmatics: Real-World Validation Using the National Health Insurance Claims Database.

The high rates of mortality and hospitalization among elderly asthmatics, as well as their increasing healthcare costs have become an important public health issue. It would be worthwhile to assess whether inhaled corticosteroid (ICS) can resolve these problems. To explore ICS prescription rates for elderly asthmatics and the factors influencing them and to investigate their association with hospitalization and healthcare costs, we analyzed data from the National Health Insurance Claims Database for the same time frame (December 1 to February 28) across three different periods (2011-2012; 2014-2015; and 2017-2018), from which we identified 6,619, 5,619, and 6,880 elderly individuals, respectively.

A diagnosis of depression should be considered in patients with multiple physical symptoms in primary care clinics.

Although the vast majority of depressed patients visit primary health care clinics, they often remain undiagnosed and untreated. Therefore, early detection in primary care settings is important. There is a high correlation between number of physical symptoms and the presence of depression, yet little has been reported regarding this relationship in Japanese primary care clinics.

Effects of smoking cessation on gastric emptying in smokers.

Background: Smoking cessation can lead to changes in appetite and weight gain in some patients; thus, smoking cessation may alter gastrointestinal motility. Effects of smoking cessation on gastric emptying in smokers have not been established.

Aim: This study sought to determine how smoking cessation affects gastric emptying in smokers.

Low expression of T-cell co-stimulatory molecules in bone marrow-derived dendritic cells in a mouse model of chronic respiratory infection with Pseudomonas aeruginosa.

Pseudomonas (P.) aeruginosa frequently colonizes the respiratory tract of patients with chronic respiratory tract infections such as diffuse panbronchiolitis (DPB). The number of dendritic cells (DCs) that play a central role in immune functions as antigen-presenting cells is reportedly increased in the bronchiolar tissues of patients with DPB.

[Two cases of pleomorphic carcinoma with severe systemic inflammation].

We report two cases of pleomorphic carcinoma with fever and severe inflammatory reaction. In case 1, an abnormal mass shadow was found on the chest X-ray film of a 63-year-old man with bloody sputum. After right upper lobectomy, the tumor was diagnosed as pleomorphic carcinoma.

[Case of nonspecific interstitial pneumonia associated with aortitis syndrome].

A 32-year-old woman was admitted to our hospital because of fever and back pain. Two months previously, she had been given a diagnosis of bacterial pneumonia based on the same symptoms and recovered after antibiotic treatment. Chest CT scans on admission showed a consolidation and thickened pleura in the right lower lobe.

Availability of cardio-ankle vascular index (CAVI) as a screening tool for atherosclerosis.

Background: A novel index, the cardio-ankle vascular index (CAVI), which reflects the stiffness of the aorta, femoral artery, and tibial artery, was recently developed by measuring brachial - ankle pulse wave velocity and blood pressure.

Methods And Results: In the present study 1,014 Japanese adults from the general population were screened to clarify the correlation between CAVI and other existing markers related to atherosclerosis, including carotid intima - media thickness (CIMT) and homocysteine (HCY). CAVI was strongly associated with age in both men and women.

Sarcoidosis accompanied by systemic lupus erythematosus and autoimmune hepatitis.

A 52-year-old woman was admitted to our hospital for further examination of blurred vision, abnormal lung shadows and an elevated level of angiotensin-converting enzyme. Sarcoidosis was suspected, however, careful history taking revealed the existence of photosensitivity and polyarthralgia. Laboratory tests showed lymphocytopenia, liver dysfunction, hypergammaglobulinemia, and positive anti-nuclear, anti-double stranded DNA and anti-smooth muscle antibodies.

Increased levels of interleukin-18 in bronchoalveolar lavage fluid of patients with idiopathic nonspecific interstitial pneumonia.

Background: Interleukin-18 (IL-18) is a proinflammatory cytokine that can induce interferon-gamma (IFN-gamma), and it plays an important role in T-helper 1 responses. Among idiopathic interstitial pneumonia (IIP), nonspecific interstitial pneumonia (NSIP) has an increased number of lymphocytes in bronchoalveolar lavage (BAL) fluid compared with usual interstitial pneumonia (UIP). However, the difference in their pathogenesis is unclear.

Elevated serum beta-defensins concentrations in patients with lung cancer.

Background: Beta-defensins (HBDs) are expressed in lung epithelial cells and act as antimicrobial agents. Most lung cancers that originate from pulmonary epithelial cells may produce HBDs.

Materials And Methods: We measured serum HBD-1 and HBD-2 levels in healthy subjects (HS), patients with lung cancer and patients with pneumonia by radioimmunoassay.

High-BAL fluid concentrations of RANTES in nonspecific interstitial pneumonia compared with usual interstitial pneumonia.

Chemokines such as regulated on activation, normal T-cell expressed and secreted (RANTES), monocyte chemoattractant protein (MCP)-1, monocyte inflammatory protein (MIP)-lalpha have been reported to play an important role in the pathogenesis of interstitial lung diseases. Among idiopathic interstitial pneumonia (IIP), nonspecific interstitial pneumonia (NSIP) has elevated percentages of Lymphocytes in bronchoalveolar lavage (BAL) fluid compared with usual interstitial pneumonia (UIP). These chemokines are candidate mediators for lymphocyte attraction to the lung in NSIR Therefore, we measured the BAL fluid levels of RANTES, MCP-1 and MIP1-alpha in 15 patients with idiopathic NSIP, 20 with idiopathic UIP, 22 with sarcoidosis and 12 healthy volunteers to evaluate the contribution of these chemokines using enzyme-linked immunosorbent assays.

Acute eosinophilic pneumonia with fine nodular shadows.

A 19-year-old woman presented with acute onset of cough and dyspnea. She started smoking two weeks before the appearance of symptoms. On admission, arterial blood gas analysis on room air breathing revealed PaO2 55 Torr.
