Abstract Background: The incidence of thrombotic complications is extremely high among severe coronavirus disease 2019(COVID-19) patients in the intensive care unit. Various factors such as a cytokine storm due to an excessive immune response to inflammation, hypoxemia, and disseminated intravascular coagulation are considered predisposing factors for thrombotic complications.Case presentation: A 55-year-old Japanese man intubated 8 days previously was referred to our hospital because of a severe COVID-19 pneumonia diagnosis after his pharyngeal swab tested positive for severe acute respiratory syndrome coronavirus 2 using reverse transcription-polymerase chain reaction. The patient continued to remain hypoxic (PaO2/FiO2 ratio <100 mmHg) at the referring hospital. On admission, we initiated veno-venous extracorporeal membrane oxygenation (VV-ECMO). Unfractionated heparin and nafamostat mesylate were used as anticoagulants during VV-ECMO. Despite the adequate anticoagulant therapy, he developed pulmonary infarction due to pulmonary embolism followed by hemoptysis. On day 10 following admission, his oxygen saturation dropped from 95% to 88%, with a marked decrease in his ventilator tidal volume, accompanied by an inability to ventilate the patient. Thereafter, we increased the VV-ECMO flow and exchanged his endotracheal tube. The lumen of the removed tracheal tube was found to be occluded by a large-sized blood coagulum. There was no further episode of tube occlusion. The patient was discharged in a walkable state on day 39 following admission. Conclusions: Endotracheal tube obstruction secondary to hemoptysis should be suggested in patients with COVID-19 requiring ventilator support, as they are not able to perform frequent endotracheal tube suctions owing to the risk of infection.

Abstract Background The common causes of failure to inflate the lungs after placement of an endotracheal tube include mechanical obstruction of the tube by tight gauzes, tongue blade, tube kinking, patient biting on the tube, obstruction of the lumen by blood or foreign body, bronchospasm, haemothorax, tension pneumothorax or equipment malfunction. Case presentation We report a case of complete airway obstruction due to herniation of the pilot inflation line into the lumen at the proximal end of a reinforced tube when the tracheal cuff was inflated. Prior to use, the endotracheal tube was tested and functioned normally. The patient was uneventfully reintubated with a new endotracheal tube. With the endotracheal tube, device problems often involve the pilot balloon and cuff assembly and leaks are more common. Conclusion This case report highlights an unusual cause of complete proximal lumen obstruction due to a manufacturing defect which could have caused a critical incident in the theatre.

Abstract Background Yersinia pseudotuberculosis infection can occur in an immunocompromised host. Although rare, bacteremia due to Y. pseudotuberculosis may also occur in immunocompetent hosts. The prognosis and therapeutic strategy, especially for immunocompetent patients with Y. pseudotuberculosis bacteremia, however, remains unknown. Case presentation A 38-year-old Japanese man with a mood disorder presented to our hospital with fever and diarrhea. Chest computed tomography revealed consolidation in the right upper lobe with air bronchograms. He was diagnosed with pneumonia, and treatment with intravenous ceftriaxone and azithromycin was initiated. The ceftriaxone was replaced with doripenem and the azithromycin was discontinued following the detection of Gram-negative rod bacteria in 2 sets of blood culture tests. The isolated Gram-negative rod bacteria were confirmed to be Y. pseudotuberculosis. Thereafter, he developed septic shock. Doripenem was switched to cefmetazole, which was continued for 14 days. He recovered without relapse. Conclusions We herein report a case of septic shock due to Y. pseudotuberculosis infection in an adult immunocompetent patient. The appropriate microorganism tests and antibiotic therapy are necessary to treat patients with Y. pseudotuberculosis bacteremia.

Abstract Background Anti-streptavidin antibodies are causal determinants of analytical interference during Thyroid function tests, and numerous reports have detailed such interference, with anti-streptavidin antibodies attracting attention. Case presentation We conducted a straightforward investigation of interference due to anti-streptavidin antibodies, with a case of a 60-year-old Japanese man who consulted our department for inconsistencies between his clinical course and Thyroid function tests. Experiments were conducted using Cobas8000 e602, which employs assay procedures with pre-wash to evaluate FT4 and FT3 levels. Conclusions To our knowledge, this is the first published report to clearly investigate such interferences using a combination of polyethylene glycol precipitation, heterophilic blocking tube precipitation, streptavidin-coated magnetic particle precipitation, and different instruments with or without pre-wash. Clinicians should consider that interferences caused by anti-streptavidin antibodies could lead to a misdiagnosis of thyrotoxicosis. Moreover, discussions between laboratory specialists, clinicians, and manufacturers are required to identify interferences and avoid unnecessary examinations and inappropriate treatment.

Objective We aimed to examine the risk factors and prognosis of nosocomial pneumonia (NP) during extracorporeal membrane oxygenation (ECMO). Methods We retrospectively analyzed data of patients who received ECMO at the Affiliated Hangzhou Hospital of Nanjing Medical University between January 2013 and August 2019. The primary outcome was the survival-to-discharge rate. Results Sixty-nine patients who received ECMO were enrolled, median age 42 years and 26 (37.7%) women; 14 (20.3%) patients developed NP. The NP incidence was 24.7/1000 ECMO days. Patients with NP had a higher proportion receiving veno-venous (VV) ECMO (50% vs. 7.3%); longer ECMO support duration (276 vs. 140 hours), longer ventilator support duration before ECMO weaning (14.5 vs. 6 days), lower ECMO weaning success rate (50.0% vs. 81.8%), and lower survival-to-discharge rate (28.6% vs. 72.7%) than patients without NP. Multivariable analysis showed independent risk factors that predicted NP during ECMO were ventilator support duration before ECMO weaning (odds ratio [OR] = 1.288; 95% confidence interval [CI]: 1.111–1.494) and VV ECMO mode (OR = 10.970; 95% CI: 1.758–68.467). Conclusion NP during ECMO was associated with ventilator support duration before ECMO weaning and VV ECMO mode. Clinicians should shorten the respiratory support duration for patients undergoing ECMO to prevent NP.
