Background: The persistent stapedial artery (PSA) is a rare congenital vascular malformation involving the middle ear. It is usually associated with pulsatile tinnitus and/or conductive hearing loss and can account for multiple risks during middle ear surgery. Case Report: we present a case of a 9-year-old male child with conductive hearing loss and persistent stapedial artery in his right ear, who was admitted to our ENT Department for hearing loss. During surgery, we discovered PSA along with congenital stapes agenesis and oval window atresia, as well as an abnormal trajectory of the mastoid segment of the facial nerve. After ossicular reconstruction (transcanal total ossicular replacement prosthesis) with cochleostomy, no surgical complications were recorded and hearing improvement was monitored by pre- and postoperative audiometry. Conclusion: Stapedial artery is a rare anatomical middle ear abnormality that can prevent proper surgical hearing restoration and can be associated with other simultaneous temporal bone malformations.
Moebius Syndrome is a rare multifactorial condition defined by congenital complete or partial VII and VIth cranial nerves palsy and other physical abnormalities. We present the case of a 3 months old infant with Moebius sequence and breathing and eating difficulties, managed by tracheostomy and laryngoplasty.
Pediatric tracheostomy in COVID‐19 patients is a rarity. Joubert syndrome is a rare genetic disease, involving a lack of muscle control. We report the case of a child with Joubert syndrome and a severe form of COVID‐19 infection, in whom we performed tracheostomy in order to replace prolonged intubation and mechanical ventilation; successful decannulation was performed after 12 months. Successful decannulation is still possible in a child with severe comorbidities (Joubert syndrome) even if it might take much longer than in patients without comorbidities.

This research study aim was to assess muscle fatigue of the dominant and non-dominant lower limb (knee flexion/extension, hip abduction/adduction and ankle plantar/dorsoflexion), using Biodex System 4 ProTM. This investigation tested the lower limb muscles during isokinetic concentric/concentric mode at 60o /sec,120o /sec, 300o /sec,450o /sec. Hip abduction/adduction of the right and left side values range for total work from 101.6 J to 528.1 J ; work first third from 32.7 J to 164.7 J; work last third from 25.2 J to 183.7 J. Knee flexion/extension of the right and left side values range for total work from 443.2 J to 792.2 J; work first third from 135.7 J to 258.7 J; work last third from 124.1 J to 249.2 J. The present study suggests that as we change the velocity, muscle fatigue can affect the kinetic lower limb chain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
