Chordoid glioma with calcification and neurofilament expression: case report and review of the literature.

Background: Chordoid glioma of the third ventricle is a rare type of brain tumor that was recently categorized as a novel tumor entity. Despite low-grade histologic features, the clinical outcome in reported cases was poor.

Case Description: A 61-year-old woman presented to our institution with a history of syncope.

Flexible, tapered-tip tube facilitates conventional orotracheal intubation by novice intubators.

Orotracheal intubation is the standard technique for airway management, but several untoward airway complications are possible with this method. To avoid airway trauma caused by the tube tip during intubation, the Parker Flex-Tip tube (PFT), which has a flexible, tapered tip, was developed. It has been reported that the PFT facilitates fiberoptic orotracheal intubation and introducer-guided tracheal intubation.

Ventilator weaning using a fenestrated tracheostomy tube with a speaking valve.

We describe two patients with tracheostomies who showed difficulty in weaning from mechanical ventilation, but were eventually weaned after use of a fenestrated tracheostomy tube with a speaking valve. The first patient underwent mechanical ventilation after pulmonary bleeding, while the second needed ventilator support because of tracheomalacia. Both patients needed only slight ventilator support but developed respiratory distress when it was discontinued.

Distorted perception of smell by volatile agents facilitated inhalational induction of anesthesia.

Background: Unpleasant smell of halogenated volatile agents is one of the frustrating factors for inhalational induction. We developed a new modification that might enable children to enjoy the smell itself while incrementally elevating sevoflurane concentration. Troposmia is usually a pathological quality change of smell perception and an olfactory stimulus is distortedly perceived in this state, which we applied to inhalational induction.
