Wearing masks and face coverings helps reduce transmission of respiratory diseases. Much prior research on mask filtration efficiency has focused fabric type, with less consideration given to design shape. Here, we present evidence that increasing the mouth-mask separation distance engenders an increase in mask-fabric toward expiratory aerosols emitted via vocalization, which attribute a decrea...

background: personal protection equipments (ppes) should be easily accessible to decrease contact with infecting factors and also should be used purposefully to effectively keep the health care personnel in a safe distance from the patient blood and body fluid which can easily infect the operating rooms personnel. this study aimed to find the operating rooms' personnel compliance with standards...

The present study aims to investigate the effects of gum rosin (GR) microspheres coating over hydrophobicity outer layer a polypropylene (PP) based surgical face mask. was deposited surface mask by electrospraying technique. deposition GR confirmed field emission scanning electron microscopy (FESEM) and Fourier transform infrared spectroscopy (FTIR) analysis. thermal analysis determined coopera...

At least 80 causes of torticollis have been documented in the literature [1]. Acutely developed torticollis may mask severe pathology requiring treatment including surgical one. First of all, it is necessary to rule out trauma as well as the destructive process of tumoral or inflammatory nature. General differential-and-diagnostic algorithms required for examination of children with torticollis...

Hypoglossal nerve palsy induces palsy in the ipsilateral lingual muscles, resulting in tongue deviation and articulation disorder. It is a rare condition that may stem from a variety of causes. Therefore, it is important to consider the possible causes of hypoglossal nerve palsy related to surgery or anesthesia, including intubation, the surgical positions, and mask ventilation during recovery.

To the Editor: We read with great interest the study by Ikeda et al.1 and the accompanying editorial.2 It is now increasingly recognized that muscle relaxants are beneficial in overcoming difficult mask ventilation in adults.2–4 However, both current papers are lacking a sufficient discussion of the reasons why muscle relaxation improves difficult mask ventilation. This can primarily be deduced...
