A Ukrainian infant with giant coronary aneurysms: A case report and literature review.

Key Clinical Message: COVID may manifest multisystem inflammatory syndrome in children (MIS-C) which mimics Kawasaki disease (KD). Differentiating KD and MIS-C is difficult. Immunomodulatory treatment should be initiated promptly without accurate diagnosis. Abstract: A febrile Ukrainian infant developed giant aneurysms in coronary arteries. Differentiating between Kawasaki disease and multisystem inflammatory syndrome in children was difficult. In both illnesses, coronary aneurysm may develop unless treated promptly. Therefore, guidelines should synthesize these clinical entities so that treatment can be initiated before rigorous diagnosis.

A Dome-Shaped Aerosol Box for Protection During a Pandemic.

With the rise of COVID-19, the use of aerosol boxes when interacting with COVID-19 patients has increased. However, their use has been controversial. We have been involved in the development of a dome-shaped aerosol containment device with negative pressure (DAWN), an aerosol box that can maintain negative pressure inside at all times. There are two types of DAWN: one is mounted on a bed (bed type) and the other is mounted on a stretcher (stretcher type). Each device has its own characteristics and can be selected depending on the situation. The bed type has enough space inside to allow procedures to be performed easily. The stretcher type can be attached to a stretcher and can maintain negative pressure when the patient is being moved. Due to the negative pressure structure and easy change of nonwoven fabric adopted in both types of DAWN, it is expected to prevent the scattering of aerosol when it is removed, which is a problem of conventional aerosol boxes. DAWN will contribute to reducing the enormous psychological stress of medical personnel who treat infections, and will contribute to reducing aerosol dispersion.
