Comparative Study Controlled Clinical TrialParaoxonase and arylesterase activity and total oxidative/anti-oxidative status in patients with chronic adenotonsillitis.
The aim of this study was to investigate serum paraoxonase, arylesterase activities along with determination of oxidative status via measurement of total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) in children with recurrent adenotonsillitis during pre- and post-adenotonsillectomy period and to compare results with data from healthy subjects. ⋯ Based on data obtained from this study, we may state that paraoxonase, arylesterase activities with TAS, TOS and OSI levels of patients with chronic adenotonsillitis shows alterations due to oxidant/antioxidant imbalance induced by frequent infections.

Comparative StudyEarly prelingual auditory development and speech perception at 1-year follow-up in Mandarin-speaking children after cochlear implantation.
The primary purpose of the current study was to evaluate early prelingual auditory development (EPLAD) and early speech perception longitudinally over the first year after cochlear implantation in Mandarin-speaking pediatric cochlear implant (CI) recipients. Outcome measures were designed to allow comparisons of outcomes with those of English-speaking pediatric CI recipients reported in previous research. ⋯ EPLAD and early speech perception exhibited similar patterns of improvement during the first 12 months after early cochlear implantation. The duration of pre-implant hearing aid use had a significant positive effect on both categories of outcome measures. Consistent post-implant EPLAD trajectories and early speech perception results provide objective evidence that can guide best practices in early intervention protocols.

Comparative StudyPredicting complications after adenotonsillectomy in children 3 years old and younger.
To identify risk factors for complications in the first 24h after surgery in the young (<4 years old) adenotonsillectomy patient. ⋯ Knowing the stated risk factors for complications in the early post-operative period after adenotonsillectomy in the younger pediatric patient can help select certain patients for closer monitoring. Specifically, children aged 1-2 years old with a history of nasal obstruction from large adenoids, gastroesophageal reflux disease, prematurity, and/or cardiovascular anomalies appear to be at higher risk for early complications and should warrant closer observation.

Comparative StudyA pilot study to identify pre- and peri-operative risk factors for airway complications following adenotonsillectomy for treatment of severe pediatric OSA.
A pilot study to identify risk factors predicting post-operative complications in children with severe OSA undergoing adenotonsillectomy. ⋯ This pilot study identified pre- and peri-operative risk factors that collectively can be investigated as predictors of post-operative airway complications in a prospective study. By identifying preliminary results comparing the complication rates between those children with and without these risk factors, we will be able to calculate the sample size for a future prospective validation study. Such a study is necessary to understand the safety and potential significant cost savings of observing children without risk factors on the pediatric floor and not in an ICU setting. A best practice algorithm can be created for children with severe OSA only after completing this prospective study.

Comparative StudyActivity of soluble aminopeptidase A and dipeptidyl peptidase IV and membrane-bound aminopeptidase B and pyroglutamyl peptidase I in adenoid hyperplasia, tonsillar hyperplasia and chronic tonsillitis.
To analyze soluble and membrane-bound peptidase activities in the tonsils and adenoids removed from patients with adenoid hyperplasia, tonsillar hyperplasia and chronic tonsillitis. ⋯ Our results suggest a potential role of soluble aminopeptidase A, soluble dipeptidyl peptidase IV, membrane-bound aminopeptidase B and membrane-bound pyroglutamyl peptidase I in the pathobiology of adenoid hyperplasia, tonsillar hyperplasia and chronic tonsillitis that is differently regulated as a function of gender. These finfings may modify in the future the clinical approach to these diseases.
