Pediatric Cholesteatoma Follow-Up: Residual and Recurrence in 239 Cases with Over 5-Year Hindsight.

Introduction: Pediatric cholesteatoma is an aggressive disease which requires long-term evaluation to assess management strategies. The objective was to determine optimal follow-up duration in pediatric cholesteatoma to detect residual and recurrent diseases.

Methods: This cohort study was set in a tertiary referral center.

Parkinson's disease pathology is directly correlated to SIRT3 in human subjects and animal models: Implications for AAV.SIRT3-myc as a disease-modifying therapy.

In Parkinson's disease (PD), post-mortem studies in affected brain regions have demonstrated a decline in mitochondrial number and function. This combined with many studies in cell and animal models suggest that mitochondrial dysfunction is central to PD pathology. We and others have shown that the mitochondrial protein deacetylase, SIRT3, has neurorestorative effects in PD models.

Multiple Copies of in Paraburkholderia unamae Regulate Flagellar Gene Expression, Motility, and Biofilm Formation.

FlhDC is a heterohexameric complex that acts as a master regulator of flagellar biosynthesis genes in numerous bacteria. Previous studies have identified a single operon encoding this complex. However, we found that two loci are present throughout , and two additional copies are also present in Paraburkholderia unamae.

[Neonatal hearing screening].

Neonatal hearing screening has been developped in a large number of countries. The rational to build such nationwide programs is robust. The prevalence of hearing impairment of various etiologies is high (1/1,000), diagnosis of hearing impairment in infants is uneasy and is made most of the time after the age of 18 months when treatment is less efficient and, last, appropriate test to screen for hearing impairment are available: Otoacoustic Emission and Auditory Evoked Potential.

International Pediatric Otolaryngology Group (IPOG) survey: Efforts to avoid complications in home tracheostomy care.

Objective: To provide guidance for home care tracheostomy management in the pediatric population. The mission of the IPOG is to develop expertise-based recommendations for the management of pediatric otolaryngologic disorders with the goal of improving patient care.

Methods: Survey of expert opinion by the members of the International Pediatric Otolaryngology Group (IPOG).
