RESUMEN
BACKGROUND: Cigarette smoking in patients with asthma leads to poor symptom control. As patients who are current smokers have been excluded from enrollment in many clinical trials on asthma, there are few reports on the treatment in current smokers with asthma. In this study, we aimed to assess how respiratory physicians manage asthma in current smokers in Japan. METHODS: Respiratory physicians in 16 Japanese hospitals answered a questionnaire on treatment for patients with asthma between December 2014 and February 2015. Medical records were reviewed for 1756 patients with asthma. RESULTS: The mean patient age was 61.1 years, and 62.9% of the patients were female. A total of 102 patients (5.8%) were current smokers, and 546 patients (31.1%) were former smokers. Long-acting muscarinic antagonists (LAMA) were prescribed more frequently for current smokers with asthma than for former smokers and never smokers with asthma (10.8% vs 4.6%, p = 0.01, 10.8% vs 3.8%, p < 0.01). In contrast, macrolides were prescribed more frequently for former smokers and never smokers with asthma than for current smokers with asthma (7.7% vs 1.0%, p = 0.01, 6.4% vs 1.0%, p = 0.03). Triple therapy, i.e., inhaled corticosteroids, long-acting beta agonists, and LAMA concomitantly, was prescribed for current smokers with asthma more frequently than for former smokers and never smokers with asthma (9.8% vs 4.0%, p = 0.01, 9.8% vs 3.3%, p < 0.01). CONCLUSIONS: According to this survey, current smokers with asthma received more intensive therapy, including LAMA, than did former smokers with asthma.

A 53-year-old man developed bilateral pleural effusion with respiratory failure. The amylase level in the pleural effusion was elevated. He had neither abdominal symptoms nor abdominal physical findings. Abdominal computed tomography (CT) also showed no abnormalities. Magnetic resonance cholangiopancreatography (MRCP) was non-diagnostic, but endoscopic retrograde cholangiopancreatography (ERCP) and subsequent CT showed a fistula connecting the pancreatic duct with the right pleural cavity. The pleural effusion was refractory to drug therapy, leading to the need for surgical intervention. The pathological findings revealed chronic pancreatitis without pseudocysts. The elevated pancreatic amylase in the pleural effusion offered an important clue to the correct diagnosis.

A 63-year-old female presented with abnormal lung shadows but had, apart from this, few symptoms. Computed tomography (CT) revealed multiple nodules and blockage of the pulmonary artery. She was immediately diagnosed with pulmonary artery sarcoma based on a careful differential diagnosis and underwent surgery. Her tumor was pathologically diagnosed as leiomyosarcoma (i.e. intimal sarcoma). Pulmonary artery sarcoma can be easily confounded with thromboembolism in a clinical setting and some cases are diagnosed post mortem only. In our case, clinical prediction scores (Wells score, Geneva score, and revised Geneva score) for the pulmonary embolism showed low probability. Moreover, chest CT showed uncommon findings for pulmonary thromboembolism, as the nodules were too big for thrombi. Because surgical resection can provide the only hope of long-term survival in cases of pulmonary artery sarcoma, clinicians should consider this possibility in the differential diagnosis of pulmonary embolism. Clinical prediction scores and CT findings might help to reach the correct diagnosis of pulmonary artery sarcoma.
RESUMEN
A 65-year-old woman presented with pain in her throat and neck. Thin-section computed tomography (CT) revealed an air-filled lesion at the right paratracheal region and two narrow connections to the trachea. Flexible bronchoscopy showed four diverticula 4-5 cm below the vocal cords in the right lateral part of the trachea. Consistent with the CT findings, two of the diverticula were deep. A radiological barium swallow study and an esopagogastroduodenal endoscopic examination revealed no abnormalities. We therefore believe that her right paratracheal air cyst is an extension of a tracheal diverticulum. Right-sided paratracheal air cysts at the level of the thoracic inlet are a common finding on CT and should not be confused with pneumomediastinum in order to avoid unnecessary examinations or treatments.
