The Academic Consortium on Emergency Medical Services and Disaster Medical Response Plan during the Tokyo Olympic and Paralympic Games in 2020 (AC2020) was launched 2016, consisting of 28 academic societies in Japan, it has released statements based on assessments of medical risk and publishing guidelines and manuals on its website. This paper outlines the issues and countermeasures for emergency and disaster medical care related to the holding of this big event, focusing on the activities of the academic consortium.
  Patients with skeletal metastasis from prediagnosed primary malignancy sometimes have concurrent oncologic emergency (OE) during the first visit. This study aims to investigate the types of OEs and treatment outcome in such patients.
 
  We have experienced 359 patients with skeletal metastasis from unknown primary malignancy. Among them, 130 patients required immediate admission for OE treatment (OE group), 229 patients had no OE and did not required immediate admission (non-OE group).
 
  The recognized types of OE were spinal cord compression in 60 patients, cancer pain in 30, hypercalcemia in 19, delirium in 16, deep vein thrombosis in 13, acute renal failure in 6, respiratory failure in 3, gastrointestinal hemorrhage in 3, and disseminated intravascular coagulation in 1. The overall 5-year survival rates were 28% and 37% in the OE and non-OE groups, respectively (
  <0.001). The multivariate analysis revealed that delirium (hazard ratio 4.2; 95% confidence interval, 1.6-12.5; 
  <0.005) and respiratory failure (hazard ratio 22.6; 95% confidence interval, 4.5-92.8; 
  <0.001) were significant prognostic factors in patients with OEs, whereas other OEs did not confer a significant risk for patient outcomes.
 
  In this study, OE was observed in as many as 36% of patients with skeletal metastasis from unknown primary malignancy. Delirium and respiratory failure were only two significant prognostic risk factors, which suggest that many of the OEs in untreated advanced cancer patients have probable chance to resolve. Early detection followed by appropriate treatment of such OEs is recommended.

Precision medicine guides treatment selection using biomarkers to select patients most likely to respond according to their inflammatory endotypes. However, when assessing response to treatment, greater precision is required. We report a case series describing treatment response to mepolizumab in four severe asthma patients, assessed by traditional methods and with objective ventilation/perfusion single photon emission computed tomography (V-P SPECT). In this series, patients with severe asthma received mepolizumab treatment with clinical outcomes recorded at commencement and at approximately 16 weeks post-treatment initiation. V-P SPECT imaging was performed before and after treatment to determine ventilation heterogeneity and perfusion, and its ability to assess treatment responsiveness. V-P SPECT shows promise as an objective measure to assess lung ventilation and perfusion to observe and assess responsiveness to mepolizumab. With quantification, this measure may allow better precision in determining treatment improvements.Interstitial lung disease (ILD) is a common complication of systemic sclerosis (SSc). Nintedanib, an antifibrotic drug, has recently been approved for treating SSc-ILD. Although there have been no reports suggesting the development of pneumothorax with nintedanib use, its safety in patients with impaired lung function is unclear. We observed the development of refractory spontaneous pneumothorax during nintedanib therapy in two patients with SSc-ILD and impaired lung function. Nintedanib use for SSc-ILD, an extensive disease, may therefore increase the risk of pneumothorax. In addition, pneumothorax is more likely to be refractory in these cases; initiation of nintedanib treatment and follow-up should be considered carefully.Mycobacterium simiae is an emerging and spreading pathogen in Iran and little data about its drug susceptibility test (DST) and no standard treatment regimen are available. We report a case of multidrug-resistant M. simiae respiratory infection in a 65-year-old woman with a history of previous Mycobacterium tuberculosis infection. The patient was treated with clarithromycin, levofloxacin, and cotrimoxazole for one year and eventually died while still suffering from respiratory problems. For DST, broth microdilution method was used according to the Clinical and Laboratory Standards Institute guidelines as well as molecular DST in clinical isolate. Mycobacterium simiae was resistant to streptomycin, moxifloxacin, clarithromycin, and cotrimoxazole antibiotics and was sensitive to clofazimine and amikacin antibiotics. Inappropriate use of antibiotics without determining the pattern of antibiotic resistance increases the likelihood of resistance and, for resistant specimens, the need to review the treatment protocol and replace antibiotics. Effectiveness based on antibiotic resistance pattern is essential.A 78-year-old man with exposure to asbestos was admitted to our hospital for back pain. A chest computed tomography showed right pleural effusion and a significant increase in the size of masses in the right chest wall over an interval of six months. He did not undergo further examinations and expired one month later. Autopsy revealed the presence of diffuse large B-cell lymphoma (DLBCL) and complicated by benign asbestos pleural effusion.  https://www.selleckchem.com/products/apr-246-prima-1met.html  We considered that this tumour had originated from the soft tissue in the chest wall based on the radiological and autopsy findings. The present report highlights that primary DLBCL of chest wall might be associated with chronic inflammation due to asbestos-related pleural diseases.
