RESUMEN
BACKGROUND: 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. CASE PRESENTATION: We encountered a patient with a pleomorphic carcinoma of the lung. This tumor produced interleukin (IL)-8, granulocyte colony-stimulating factor and IL-6, which in turn recruited inflammatory cells, such as CD8 positive lymphocytes, around the tumor, resulting in a rapidly growing tumor shadow. CONCLUSION: 18 F-fluoro-deoxy-glucose positron emission tomography, in addition to a conventional radiological approach such as computed tomography, may detect immunological responses around a tumor.

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 radiological features, as well as outcome, in SPE-PD. METHODS: Patients' records were retrospectively reviewed and 12 patients with SPE-PD were identified (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 two patients fulfilled the criteria of systemic inflammatory response syndrome; most of the subjects 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 9 (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.

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, 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: Our network system may improve asthma control and adherence to inhalation regimens.

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.

Purpose: Episodic nocturnal hypercapnia (eNH) caused by rapid eye movement (REM) sleep-related hypoventilation is often noted in patients with advanced COPD. The purpose of this study was to clarify the clinical significance of eNH and the effectiveness of eNH-targeted noninvasive positive pressure ventilation (NPPV). Patients and methods: We enrolled patients with stable, severe, or very severe COPD with daytime arterial partial oxygen pressure PaO2 ≥55 mmHg and daytime arterial partial carbon dioxide pressure PaCO2 <55 mmHg, who underwent overnight transcutaneous carbon dioxide pressure (PtcCO2) monitoring from April 2013 to April 2016. We retrospectively compared clinical characteristics, daytime blood gas analysis, frequency of exacerbation, serum albumin levels, and ratio of pulmonary artery to aorta diameter (PA:A ratio), between patients with COPD with and without eNH. For those with eNH, we applied NPPV and compared these clinical characteristics before and after NPPV. Results: Twenty-one patients were finally included in this study. Ten patients (47.6%) were evaluated to have eNH. These patients had lower albumin levels (p=0.027), larger PA:A ratio (p=0.019), and higher frequency of exacerbations during the last year (p=0.036). NPPV for the patients with eNH improved daytime PaCO2 compared with that 12 months after NPPV (p=0.011). The frequency of exacerbations 1 year before NPPV decreased 1 year after NPPV (p=0.030). Serum albumin levels improved 1 year after NPPV (p=0.001). Conclusion: In patients with stable severe or very severe COPD, eNH may be a risk factor of exacerbations, hypoalbuminemia, and pulmonary hypertension. NPPV may be effective against hypoalbuminemia and acute exacerbations. However, further study is necessary to validate these findings.

We report a case of drug-induced pleuritis possibly due to Hochuekkito. Hochuekkito, a Chinese-Japanese herbal medicine, was prescribed for a 33-year-old woman with panic disorder and depressive state. About 10 weeks after the first administration, she was admitted complaining of chest pain and cough. Chest X-ray and computed tomography showed the right pleural effusion. Thoracocentesis revealed eosinophilic pleuritis. Discontinuation of Hochuekkito resulted in improvement of the clinical findings. Based on the clinical course, we considered this case to be Hochuekkito-induced pleuritis.

BACKGROUND: Severe asthma is often associated with sinonasal diseases. Shin'iseihaito is a Japanese traditional herbal medicine, which is used to treat rhinosinusitis. However, its effectiveness in the treatment of asthma has not been elucidated. OBJECTIVE: The aims of this study were to examine the effectiveness of Shin'iseihaito in asthmatic patients with upper airway disease and to identify the characteristics of responders. METHODS: The medical records were retrospectively analyzed of asthmatic patients concomitant with upper airway disease in the outpatient department who had been administered Shin'iseihaito at least once from September 2011 to February 2015. They were classified into responders and non-responders, and the differences in characteristics were compared between the two groups. RESULTS: Shin'iseihaito was effective in 21/40 (52.5%) patients. There was no significant difference between responders and non-responders with regard to age, sex, or age of asthma onset. However, the frequency of aspirin intolerance, the treatment step of asthma, and serum immunoglobulin E levels were significantly higher in responders than they were in non-responders (p = 0.022, p = 0.017, and p = 0.017, respectively). The frequency of occurrence of concomitant eosinophilic chronic rhinosinusitis was not significantly different in both groups. CONCLUSION: Shin'iseihaito could be a potential alternative for the treatment of asthma in patients with upper airway diseases.

A 49-year-old man was urgently admitted due to edema in both leg and left toe pain. A chest radiograph revealed a solitary nodule in the right lung field. Detailed investigations including bronchoscopy and renal biopsy led to a simultaneous diagnosis of clinical stage IIIB pulmonary adenocarcinoma, minimal change nephrotic syndrome, antiphospholipid syndrome, and warm-type autoimmune hemolytic anemia. Prednisolone was administered for nephrotic syndrome, antiphospholipid syndrome and warm-type autoimmune hemolytic anemia, and 6 courses of chemotherapy with 70Gy radio-therapy were performed. The pulmonary nodule significantly decreased in size and the other three autoimmune diseases appeared to be well-controlled. Thirteen months after admission, multiple brain metastases developed along with worsening antiphospholipid syndrome symptoms including lupus anticoagulant. Following whole-brain irradiation, the brain metastases decreased in size and antiphospholipid syndrome symptoms improved. Thirty-nine months after the initial visit, the primary lung cancer, its brain metastasis and the 3 other autoimmune diseases appeared to be well-controlled. The temporal correlation of the lung cancer and the three autoimmune diseases suggests the latter may be paraneoplastic syndrome.

A 66-year-old man complaining of fever was given intravenous antibiotic therapy, but he did not improve. After subsequent admission, chest X-ray film and computed tomography scans showed large bullae and consolidation in the right lung field. A transbronchial lung biopsy specimen revealed infiltration of mononuclear cells in alveolar septa and organizing lesions in alveolar ducts. We considered this case to be cryptogenic organizing pneumonia (COP) from its clinical course and pathological findings. Treatment with corticosteroid resulted in disappearance of the large bullae and consolidations. COP accompanied by large bullae is very rare. The large bullae may have been caused by check-valve mechanism.

Air leakage persisted from the lung in three cases of spontaneous pneumothorax. Pleurodesis with autologous blood ended in failure. Autologous blood plus OK-432 was instilled into the thoracic cavity from the chest drainage tube. Air leakage was stopped without serious side effects and the chest tube was removed uneventfully. Although the long-term outcome of this treatment is not known, pleurodesis using autologous blood plus OK-432 may be an effective way of treatment for spontaneous pneumothorax in cases with high surgical risk.

BACKGROUND: Asthma and rhinitis are common diseases that often occur concomitantly. However, in patients with asthma, the concurrent assessment of seasonal variation in rhinitis and asthma symptoms has not been comprehensively addressed. We prospectively evaluated seasonal changes in rhinitis and asthma symptoms over one year. METHODS: Fifty-six patients with asthma were enrolled. Asthma and rhinitis symptoms were assessed by using the State of the Impact of Allergic Rhinitis on Asthma Control (SACRA) questionnaire, developed and validated in Japan by the committeeãof Global Initiative for Asthma and the committee of Allergic Rhinitis for asthma and its impact on Asthma. RESULTS: Fifty-three patients completed the study. Forty-five patients (85%) had nasal symptoms during at least one or more seasons and 15 patients (28%) had perennial rhinitis. The association between asthma symptoms and rhinitis symptoms, assessed by a visual analogue scale (VAS), was significant during each season; seasonal variations of symptoms were synchronous. Uncontrolled asthma was more prevalent in patients with moderate-to-severe rhinitis compared to those with mild rhinitis. The VAS score of asthma symptoms in patients with asthma and perennial rhinitis was significantly higher than that in patients with non-perennial rhinitis or without rhinitis, across every season, except for spring. Correlations were more significantn patients less than 65 years of age than in older patients. CONCLUSION: Rhinitis is common in patients with asthma. Symptoms of rhinitis and asthma often co-exist, and the association between these symptoms may be stronger n younger patients with asthma than older.

We report a case of acute pulmonary edema appearing soon after relief of an acute upper airway obstruction. The patient choked on some pieces of beef during dinner and fainted. He was quickly aided by paramedics and taken to our emergency room with persistent dyspnea and wheezing. His chest radiograph showed bilateral pulmonary edema predominantly distributed in the upper lung field, and high-resolution CT (HRCT) revealed that the pulmonary edema was mainly in the interstitium. The patient recovered uneventfully. HRCT clearly disclosed the characteristics of pulmonary edema of acute upper airway obstruction.

A 70-year-old man with liver cirrhosis and previous gastrectomy admitted for fever, coughing, and bloody sputum soon after convalescing from pulmonary tuberculosis had a peripheral white blood cell count of 9,900/microL, C-reactive protein of 14.1mg/dL, serum albumin of 2.0g/dL, and serum positive for antiaspergillus and beta-D glucan antibodies. Chest radiography showed thickening of the walls of the large residual cavities with previous tuberculosis lesions and infiltrates around them. On day 2 of hospitalization, Aspergillus fumigatus without other bacillus was detected in sputum culture taken on admission. Despite immediate treatment with intravenous micafungin and oral itraconazole and improved brief initial improvement, his general condition abruptly deteriorated into frequent massive hemoptysis and he developed of shock, respiratory failure, and severe malnutrition, dying 30 days later. Autopsy findings showed pulmonary aspergillosis in and around the large cavities and on the other side of the lungs. Pulmonary aspergillosis without hematological malignanciy and immunosuppression can thus be abruptly severe and fatal due to malnourishment stemming from pre-existing conditions such as chronic hepatitis despite prompt, ordinarily adequate medical treatment.

We reported three sisters of pulmonary Mycobacterium avium complex (MAC) disease. The oldest sister was complaining of bloody sputum, and cultures were positive for M. avium. By monotherapy with clarithromycin, symptom and imaging findings had shown no progression for six years. The second sister was complaining of productive cough, and cultures were positive for M. intracellulare. Her symptom and imaging findings had shown no progression for seven years without any treatment. The third sister had rheumatoid arthritis and diabetes mellitus, and cultures were positive for M. intracellulare. Although she received chemotherapy with rifampicin, clarithromycin, ethambutol, and kanamycin, symptom and imaging findings had progressed gradually. She died of respiratory failure four years later. Autopsy findings revealed no disseminated MAC disease. The results which three cases showed different isolate patterns and clinical courses suggest the importance of underlying anti-mycobacterial immunological impairment and defects of local host defense rather than virulence of infected strains as the pathogenesis of pulmonary MAC disease.

A 27-year-old man was admitted to our hospital due to a painful mass in the right neck and fever. Cervical and superior mediastinal computed tomography showed an enlargement of right supraclavicular lymph node and multiple swollen mediastinal lymph nodes, including low-density areas and contrast medium-enhanced septa and margins. Smears of the pus obtained from right supraclavicular lymph node showed acidfast bacilli identified as Mycobacterium tuberculosis by PCR method. He was treated with antituberculous drugs with INH, RFP, EB, and PZA. PZA was given for initial two months. Six months later, productive cough developed and chest X-ray films showed infiltrative shadow in the right upper lung field. One month after the onset of cough, bronchoscopy revealed a polypoid lesion with a white coating in the right main bronchus. Microscopic examination of the specimen obtained by transbrochial biopsy revealed many epithelioid cell granulomas, consistent with tuberculosis. From these findings, pulmonary lesion was suggested to be due to invasion of the mediastinal lymph node into the bronchus. After one year of antituberculous chemotherapy, the swelling of the cervical-mediastinal lymph nodes was reduced and the abnormal chest X-ray shadows disappeared.

A 59-year-old man took mefloquine (antimalarial drug), total dose of 1,000 mg, to prevent malaria before and during traveling to South Africa. Three weeks after the first administration, he was admitted complaining of fever and dyspnea. Chest HRCT showed ground-glass opacities and consolidation in both lung fields. Withdrawal of mefloquine and treatment with corticosteroid resulted in improvement of the clinical findings. From the clinical course, we considered this case to be mefloquine-induced pneumonia. Mefloquine may have caused pulmonary toxicity.

OBJECTIVES: Inhaled corticosteroid (ICS) treatment has been shown to increase the risk of respiratory complications in patients with stable chronic obstructive pulmonary disease (COPD). However, the effects of perioperative ICS treatment on postoperative respiratory complications after lung cancer surgery have not been elucidated. The aim of this study was to investigate whether perioperative ICS treatment would increase the risk of postoperative respiratory complications after lung cancer surgery in patients with COPD. METHODS: We retrospectively analyzed 174 consecutive COPD patients with non-small-cell lung cancer (NSCLC) who underwent lobectomy or segmentectomy between January 2007 and December 2014. Subjects were grouped based on whether or not they were administered perioperative ICS treatment. Postoperative cardiopulmonary complications were compared between the groups. RESULTS: There were no statistically significant differences in the incidence of postoperative respiratory complications (P = 0.573) between the perioperative ICS treatment group (n = 16) and the control group (n = 158). Perioperative ICS treatment was not significantly associated with postoperative respiratory complications in the univariate or multivariate analysis (odds ratio [OR] = 0.553, 95% confidence interval [CI] = 0.069-4.452, P = 0.578; OR = 0.635, 95% CI = 0.065-6.158, P = 0.695, respectively). Kaplan-Meier analysis showed that there were no statistically significant differences in the postoperative respiratory complications-free durations between the groups (P = 0.566), even after propensity score matching (P = 0.551). CONCLUSION: There was no relationship between perioperative ICS administration and the incidences of postoperative respiratory complications after surgical resection for NSCLC in COPD patients.

Acute respiratory distress syndrome (ARDS) developed following intravenous gemcitabine monotherapy in a 75-year-old man with non-small cell lung cancer. The total dose of gemcitabine was 1,500 mg, and the latent period from starting gemcitabine to pulmonary toxicity was three days. The chest radiographs and high resolution computed tomographic scan revealed bilateral ground-glass opacity. He died on the fourteenth post-chemotherapeutic day due to respiratory failure. Postmortem examination of the lung revealed mixed exudative and fibrotic stages of diffuse alveolar damage. Pulmonary toxicity from gemcitabine can be acute and fatal.

We presented a case of pulmonary Rhizops microsporus var. rhizopodiformis infection which developed abruptly during treatment of bronchial asthma by systemic corticosteroids. The patient, an 85 year-old-woman, was given systemic steroid therapy for 15 days. She suddenly became febrile two days after the therapy and was coughing up yellow sputum. Chest X-ray film showed multiple nodules with cavities which became worsened rapidly. A specimen of sputum culture gave a growth of Mucoraceae, which was identified to be Rhizopus microsporus var. rhizopodiformis. She was given amphotericin B and miconazole was added on the basis of MIC value of the strain. Although she improved initially, her clinical course showed neutropenia, pseudomembranous enterocolitis, malnutrition, and then died after about six months. Because the diagnosis of pulmonary mucormycosis is difficult and prognosis is poor, further studies for investigating clinical features would be necessary.
