Regarding extracorporeal membrane oxygenation (ECMO) support against hemorrhagic conditions, there seems to be a dilemma when deciding between maintaining the circuit patency by systemic anticoagulation and increasing the risk of bleeding. We herein report two cases of diffuse alveolar hemorrhage (DAH) caused by myeloperoxidase (MPO) anti-neutrophil cytoplasmic autoantibody-associated vasculitis (AAV) successfully treated with venovenous (VV)-ECMO support, both initially started without systemic anticoagulation. Under anticoagulation-free ECMO management, we should consider the shortcomings of frequent circuit exchange and hemorrhagic diathesis related to circuit-induced disseminated intravascular coagulation (DIC).

Review Case Reports
Mirizzi Syndrome Type IV Successfully Treated with Peroral Single-operator Cholangioscopy-guided Electrohydraulic Lithotripsy: A Case Report with Literature Review.
A 76-year-old man presented with liver dysfunction and intrahepatic bile duct dilatation. Imaging studies showed two large stones that had become impacted in the common hepatic duct, which was fused with the gallbladder. The patient was diagnosed with Mirizzi syndrome type IV. ⋯ The bile flow was temporarily restored; however, the patient experienced cholangitis 16 months later. The stones were extracted via peroral single-operator cholangioscopy (SOC)-guided electrohydraulic lithotripsy. This is the first case in which stones were completely removed by SOC-guided treatment in a patient with Mirizzi syndrome type IV.

Review Case Reports
A Case of a Mild Clinical Phenotype with Myopathic and Hemolytic Forms of Phosphoglycerate Kinase Deficiency (PGK Osaka): A Case Report and Literature Review.
Phosphoglycerate kinase (PGK) deficiency is an X-linked disorder characterized by a combination of hemolytic anemia, myopathy, and brain involvement. We herein report a Japanese man who had several episodes of rhabdomyolysis but was training strenuously to be a professional boxer. Mild hemolytic anemia was noted. ⋯ S62N, was identified in the PGK1 gene. A literature review revealed only one case with a mixed hemolytic and myopathic phenotype like ours. This mild phenotype indicates the complex pathophysiology of PGK deficiency and suggests the benefits of dietary control and exercise.

Objective Although the absence of a runny nose and sore throat, both ear-nose-throat (ENT) symptoms, suggests community-acquired pneumonia (CAP), the association between ENT symptoms and coronavirus disease 2019 (COVID-19) pneumonia remains unclear. We therefore investigated the association between ENT symptoms and COVID-19 pneumonia. Methods We retrospectively recruited consecutive confirmed COVID-19 inpatients with and without pneumonia admitted to a single institution from April 1, 2020, to July 31, 2021. ⋯ Univariable analyses found mean odds ratios of 0.59 and 0.61 and 95% confidence intervals (CIs) of 0.30-1.16 and 0.32-1.17 for runny nose and sore throat, respectively, and multivariable analyses found mean odds ratios of 0.73 and 0.70 and 95% CIs of 0.34-1.56 and 0.34-1.46, respectively. Conclusion Our study found no statistically significant association between ENT symptoms and COVID-19 pneumonia. Clinicians should be aware that, unlike CAP, there is no correlation between ENT symptoms and pneumonia among patients with COVID-19, so it is necessary to consider the possibility of pneumonia even in the presence of ENT symptoms.

Bow hunter's stroke is a rare cause of vertebrobasilar infarction. There is no consensus regarding the optimal treatment. We herein report a case of bow hunter's stroke successfully treated by endovascular treatment. ⋯ Dynamic angiography revealed thrombus formation and hypoperfusion of the right vertebral artery upon head rotation to the left. Endovascular parent artery occlusion of the right vertebral artery was performed, and there was no recurrence at follow-up MRI. Endovascular parent artery occlusion might be a useful treatment for bow hunter's stroke.
