Abstract We present a case of a 69-year-old man who had localized pleural metastasis without other organ metastases after nephrectomy for right renal cell carcinoma (RCC). He complained of respiratory symptoms for more than two years after the operation and was confirmed to have right pleural effusion and multiple pleural masses on computed tomography (CT). There were no abnormal findings in the other organs, but the pleural mass gradually increased in size on CT. We suspected malignant tumors s...

BACKGROUND Chronic obstructive pulmonary disease (COPD) typically includes neutrophilic airway inflammation and eosinophilic inflammation in some cases. Inhaled corticosteroid (ICS) suppresses eosinophilic inflammation of the airway and reduces acute exacerbation (AE). The present study investigated the relationship between ICS and AE in patients with COPD classified by blood eosinophil counts. METHODS Overall, 244 patients with COPD were retrospectively evaluated between 2014 and 2017 and class...

This is a first observational study of four patients on steroid pulse therapy for secondary organizing pneumonia with respiratory failure due to the Coronavirus Disease 2019 (COVID-19) in our hospital. All patients needed invasive mechanical ventilation and had bimodal worseness of their respiratory status with organizing pneumonia after intubation. All cases could successfully discontinue oxygen therapy without any severe adverse events after this pulse therapy. Although few previous reports sh...

Abstract Here we describe the case of a 78-year-old man with respiratory failure and right pleural effusion. Computed tomography showed right pleural effusion with pleural calcification, tumor-like shadows induced by passive atelectasis, and enlarged mediastinal lymph nodes. Positron emission tomography showed right pleural thickening, rounded atelectasis, and enlarged mediastinal lymph nodes, without fluid accumulation in other organs. The pleural effusion showed lymphocyte-dominated exudates w...

In general, we have to assume tuberculous pleurisy when a patient presents with pleural effusion and elevated adenosine deaminase (ADA). However, other diseases need to be considered, including immunoglobulin (Ig)G4-related disease (IgG4-RD). This case involved a 65-year-old asymptomatic man with right pleural effusion showing elevated ADA. He had no articular findings or rashes. Results were negative for all autoantibodies. Pleura, mediastinal lymph nodes, and areas around the aorta and vertebr...

Although some prospective studies provided the evidence of corticosteroids for critically ill patients with COVID-19, the optimal dosage or timing of corticosteroids is still unknown. This is a case series of four patients on methyl-prednisolone pulses for the late phase of Coronavirus disease 2019 (COVID-19) with respiratory failure in our hospital. All patients needed invasive mechanical ventilation and had bimodal worseness of their respiratory status with consolidation and volume loss after ...

: Chylothorax is the accumulation of lipid pleural effusion. Few reports have described chylothorax caused by gastric cancer. A 45-year-old woman presented with progressive lymphedema and bilateral chylothorax. Although repetitive thoracentesis was performed to relieve her dyspnea, swelling of her axillary lymph nodes became significant. Positron emission tomography/computed tomography demonstrated the accumulation of 18F-fluorodeoxyglucose in these nodes, and a lymph node biopsy showed signet r...

BACKGROUND: We investigated the measurement of end-tidal partial pressure of carbon dioxide (PETCO2) with a capnometer in patients with respiratory failure, and we determined whether this technique could provide an alternative to measurement of PaCO2 using arterial blood gas analysis in the clinical setting. METHODS: We measured PETCO2 in subjects with hypoxemic and hypercarbic respiratory failure using a capnometer. We simultaneously measured PaCO2, venous partial pressure of carbon dioxide (Pv...
