BACKGROUND Adherence to inhalation therapy is a critical determinant of the success of asthma management. Reasons for nonadherence have been well studied, but reasons for good adherence are poorly understood. Understanding the mechanisms of adherence to inhalation therapy is important in developing strategies to promote adherence. The objective of this(More)
INTRODUCTION Nonadherence to inhalation therapy is very common in patients with chronic obstructive pulmonary disease (COPD). Few data are available to support the role of community pharmacists in optimizing inhalation therapy in COPD patients. Since 2007, the Kitano Hospital and the Kita-ku Pharmaceutical Association have provided a network system for(More)
PURPOSE Adherence to inhalation therapy is a critical determinant of the success of chronic obstructive pulmonary disease (COPD) management. However, in practice, nonadherence to inhalation therapy is very common in COPD patients. The effects of adherence to inhalation therapy in COPD have not been fully studied, and less is known about the relationship(More)
OBJECTIVE The availability of many types of inhalers in the treatment of asthma has resulted in a wide range of prescription choices for clinicians. With so many devices available, however, there is some confusion regarding their proper use among both medical staff and patients. Since 2007, Kitano Hospital and Kita-ku Pharmaceutical Association, Osaka,(More)
BACKGROUND Dyspnea on exertion (DOE) is a major symptom of chronic obstructive pulmonary disease (COPD) and is difficult to control. This study was performed to determine whether acupuncture is superior to placebo needling in improving DOE in patients with COPD who are receiving standard medication. METHODS Sixty-eight of 111 patients from the Kansai(More)
Lung cancer cells have been reported to produce cytokines, resulting in systemic reactions. There have been few reports showing that these cytokines induced the formation of an inflammatory mass around lung cancers. We encountered a patient with a pleomorphic carcinoma of the lung. This tumor produced interleukin (IL)-8, granulocyte colony-stimulating(More)
Although bevacizumab has several adverse effects, pneumothorax is rare. This is the first case of initial treatment using an Endobronchial Watanabe Spigot (EWS) for pneumothorax after bevacizumab-containing chemotherapy. A 56-year-old woman with recurrent breast cancer was treated with bevacizumab. Pneumothorax occurred 6 days after the last administration(More)
BACKGROUND The introduction of second-generation QuantiFERON-TB (QFT) enables the diagnosis of Mycobacterium tuberculosis (TB) infection with high specificity and sensitivity. This in vitro diagnostic test uses 2 TB-specific proteins (ESAT-6 and CFP-10) to stimulate cells in heparinized whole blood and detects interferon-gamma (IFN-gamma) produced from(More)
Optimal oxygen delivery is an essential component of therapy for patients with respiratory failure. Reservoir masks or air entrainment nebulizers have often been used for patients who require highly concentrated oxygen, but these may not actually deliver a sufficient fraction of inspired oxygen if there is a marked increase in the patient's ventilatory(More)
A 56-year-old man with allergic bronchopulmonary aspergillosis (ABPA) was admitted due to the appearance of nodular opacities in the right upper lung field on chest radiography, after discontinuing itraconazole and clarithromycin on the suspicion of possible hepatic adverse effects. Chest CT scans on admission revealed nodular opacities in the right S3 and(More)
