Endoscopic treatment in pediatric patients with recurrent and H-type tracheoesophageal fistulas - A systematic review and meta-analysis.

Objectives: Endoscopic treatments for managing recurrent tracheoesophageal fistula (rTEF) and H-type TEF are being utilized lately; however, the preferred technique is yet to be determined. We aimed to systematically review existing publications on endoscopic treatment of rTEF and H-type TEF to analyze their success and complication rates.

Methods: PRISMA guidelines were followed.

Patient reported outcome measures in unilateral aural atresia treated using a transcutaneous bone conduction implant (The Cochlear Baha Attract®).

Objectives: Unilateral aural atresia (UAA) is a congenital condition that is associated with maximal conductive hearing loss. The primary objective of this study was to assess the long-term compliance, complications, and quality of life of pediatric patients with UAA who had transcutaneous bone conduction hearing implants (TCBI).

Methods: Retrospective consecutive case series at a single centre between 2014 and 2018.

Single-use device endoscopy for the diagnosis of acute bacterial rhinosinusitis in primary care: A pilot and feasibility study.

Objective: Antibiotics are largely overprescribed for acute rhinosinusitis in primary care, mainly due to the lack of diagnostic tests to confirm or rule out bacterial infection. The study objective was to assess the on-site applicability and safety of the newly developed JGG endoscope for the diagnosis of acute bacterial rhinosinusitis in primary care.

Design: Five Swiss primary care centres and one university-affiliated ENT unit participated in this single-arm pilot study.

Strategies for restarting Pediatric Otolaryngology outpatient clinics after a pandemic-related shutdown such as from COVID-19.

The novel coronavirus 19 SARS-CoV2 caused a change in the practice of Otolaryngology around the globe. The high viral load in the nasal cavity, nasopharynx and airway subjects Otolaryngologists to a high risk of catching the virus during aerosol generating procedures. After the first outbreak wave has subsided, many teams are now discussing how our 'new normal' practice will look.

Induction of mitophagy in the HEI-OC1 auditory cell line and activation of the Atg12/LC3 pathway in the organ of Corti.

Autophagy is a highly evolutionary conserved quality control defense mechanism within cells, which has also been implicated in cell death processes. In the mammalian inner ear, autophagy has been shown to play a role during early morphogenesis as well as in adult cochlear hair cells exposed to ototoxic insults. Mitophagy, a selective autophagic cell process targeting mitochondria, hasn't been studied in the inner ear so far.

Effects of peroxisome proliferator activated receptors (PPAR)-γ and -α agonists on cochlear protection from oxidative stress.

Various insults cause ototoxicity in mammals by increasing oxidative stress leading to apoptosis of auditory hair cells (HCs). The thiazolidinediones (TZDs; e.g.

Simvastatin Results in a Dose-Dependent Toxic Effect on Spiral Ganglion Neurons in an In Vitro Organotypic Culture Assay.

Statins are inhibitors of the 3-hydroxy-3-methylglutaryl-coenzyme A reductase, an enzyme necessary for the production of mevalonate. They are widely used as cholesterol-lowering drugs. However, conflicting data about the effect of statins on neuronal cells has been published.

Metformin Protects Auditory Hair Cells from Gentamicin-Induced Toxicity in vitro.

Metformin is a commonly used antidiabetic drug. It has been shown that this drug activates the AMP-activated protein kinase, which inhibits downstream the mammalian target of rapamycin. In addition, several studies indicate that metformin reduces intracellular reactive oxygen species.

Inhibition of mTOR by Rapamycin Results in Auditory Hair Cell Damage and Decreased Spiral Ganglion Neuron Outgrowth and Neurite Formation In Vitro.

Rapamycin is an antifungal agent with immunosuppressive properties. Rapamycin inhibits the mammalian target of rapamycin (mTOR) by blocking the mTOR complex 1 (mTORC1). mTOR is an atypical serine/threonine protein kinase, which controls cell growth, cell proliferation, and cell metabolism.

Role of somatostatin receptor-2 in gentamicin-induced auditory hair cell loss in the Mammalian inner ear.

Hair cells and spiral ganglion neurons of the mammalian auditory system do not regenerate, and their loss leads to irreversible hearing loss. Aminoglycosides induce auditory hair cell death in vitro, and evidence suggests that phosphatidylinositol-3-kinase/Akt signaling opposes gentamicin toxicity via its downstream target, the protein kinase Akt. We previously demonstrated that somatostatin-a peptide with hormone/neurotransmitter properties-can protect hair cells from gentamicin-induced hair cell death in vitro, and that somatostatin receptors are expressed in the mammalian inner ear.
