    ABSTRACT: 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.

    ABSTRACT: 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 delivering correct inhalation techniques through certified community pharmacists. The effects of this network system on clinical outcomes in COPD patients were examined. A total of 88 consecutive outpatients with COPD at baseline and 82 of those 4 years later were recruited from the respiratory clinic of Kitano Hospital Medical Research Institute. Measurements included the frequency of COPD exacerbations, patients' adherence to inhalation therapy using a five-point Likert scale questionnaire, and patients' health status both prior to this system and 4 years later. Usable information was obtained from 55 patients with COPD at baseline, and from 51 patients 4 years later. Compared with baseline values, a significant decrease was observed in the frequency of COPD exacerbations (1.5 ± 1.6 versus 0.8 ± 1.4 times/year, P = 0.017). Adherence to the inhalation regimen increased significantly (4.1 ± 0.7 versus 4.4 ± 0.8, P = 0.024), but health status was unchanged. At 4 years, of 51 COPD patients, 39 (76%) patients who visited the certified pharmacies showed significantly higher medication adherence than those who did not (4.6 ± 0.6 versus 3.9 ± 1.0, P = 0.022). The network system may improve COPD control and adherence to inhalation regimens.

    ABSTRACT: SUMMARY AT A GLANCE: Septic pulmonary embolism due to periodontal disease (SPE-PD) is rarely reported. We retrospectively reviewed 12 patients with SPE-PD. Most of the cases were not seriously ill. With early diagnosis by contrast-enhanced chest CT, appropriate antimicrobial therapy, and periodontal surgery, resolution of the illness can be expected in most patients. ABSTRACT: Background and Objective:  Septic pulmonary embolism due to periodontal disease (SPE-PD) is rarely reported and little is known about its clinical features. The purpose of this study was to evaluate the clinical and radiologic features, as well as outcome, in SPE-PD. Methods:  We retrospectively reviewed patients' records and identified 12 patients with SPE-PD (10 men, mean age 60.5 years). The patients' demographic features, laboratory data, physical and radiological findings, and clinical outcomes were evaluated. Results:  All but one patient were smokers. Eight of the 12 patients had comorbidities including hypertension (58%) and/or diabetes mellitus (17%). Prevalent symptoms were fever (67%) and chest pain (58%). Only 2 patients fulfilled the criteria of systemic inflammatory response syndrome (SIRS); most of the cases were not clinically severely ill. Blood cultures were negative in all cases. Contrast-enhanced chest computed tomography (CT) showed multiple peripheral nodules in all 12 patients, wedge-shaped peripheral lesions abutting on the pleura in 10 (83%), and a feeding-vessel sign in nine (75%). All patients recovered from their illness after antimicrobial therapy concomitant with tooth extraction or periodontal care. The median duration of antibiotic administration was 51 days. Conclusions:  Most patients with SPE-PD were not seriously ill. Contrast-enhanced chest CT appeared to be useful to diagnose SPE-PD. © 2012 The Authors.

    ABSTRACT: 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, Japan, have provided a network system for delivering instruction on correct inhalation technique through community pharmacists. We examined the clinical effects of this network system. Our measurements included the manner in which community pharmacists instruct patients with asthma, the frequency of asthma exacerbations, patients' adherence to inhalation therapy using a 5-point Likert scale questionnaire, and patients' health status both prior to this system and at 4 years after. Usable information was obtained from 53 community pharmacists and 146 patients with asthma at baseline and from 60 community pharmacists and 148 patients at 4 years. When compared with baseline values, significant improvement was found in pharmacists' instruction and significant decreases were observed in the frequency of asthma exacerbations (1.4 ± 1.6 vs. 1.0 ± 1.4 times/yr, p = .042) and emergency room visits (0.5 ± 1.0 vs. 0.2 ± 0.5 times/yr, p = .004). Adherence to the inhalation regimen significantly increased (4.0 ± 0.7 vs. 4.2 ± 0.8, p = .041), but health status was unchanged. Our network system may improve asthma control and adherence to inhalation regimens.

    ABSTRACT: 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 demands, or if oxygen flow becomes limited due to high resistance in the nebulizer nozzles. The HighFO nebulizer is a novel air entrainment nebulizer equipped with unique structures which reduce nozzle resistance, and as a result, it is possible to supply a sufficient flow of highly concentrated-oxygen. The purpose of this study was to evaluate the effectiveness and usefulness of the HighFO nebulizer in 10 respiratory failure patients with severe hypoxemia who used a reservoir mask and required more than 10 L/min of oxygen supply. In each case, the reservoir mask was replaced with the HighFO nebulizer, and changes in percutaneous oxygen saturation (SpO2) were monitored using pulse oximetry. Oxygenation improved promptly after the reservoir mask was substituted for the HighFO nebulizer (SpO2 : 83.7% +/- 8.5%-94.2% +/- 3.2%, p = 0.007). This finding suggests that the HighFO nebulizer was reasonably effective in delivering highly concentrated oxygen, sufficient for patient demands. The HighFO nebulizer may be the beginning of a new strategy for oxygen therapy.
