School Hearing Screening With a Portable, Tablet-Based, Noise-Attenuating Audiometric Headset in Rural Nicaragua.

Objective: To investigate the utility and effectiveness of a noise-attenuating, tablet-based mobile health system combined with asynchronous telehealth evaluations for screening rural Nicaraguan schoolchildren for hearing loss.

Study Design: Prospective population-based survey.

Setting: Rural Nicaraguan communities.

Transcutaneous Radiofrequency Microneedling in the Facial Plastic Surgeon's Practice: A Review.

Minimally invasive methods for skin rejuvenation are in high demand. A diverse array of minimally invasive devices has been developed for aesthetical purposes and should be considered to help patients achieve their goals. Radiofrequency (RF) microneedling is a safe and effective intervention for treatment of various aesthetical and dermatological conditions in all skin types.

The Role of Subcutaneous Radiofrequency-Assisted Liposculpture in the Facial Plastic Surgeon's Practice.

Percutaneous radiofrequency-based skin tightening procedures can offer patients an option to undergo a potential treatment for skin laxity and excess adipose of the face and neck with less downtime, lower cost, and decreased risk of complications compared with more aggressive open procedures such as neck lift, face and neck lift, and platysmaplasty. FaceTite and AccuTite can safely yet effectively deliver energy into the subdermal space, targeting the dermal collagen network and deeper fascial layer. Ideal candidates have early jowl formation, mild to moderate skin laxity, and submental adiposity.

Community health workers and mHealth systems for hearing screening in rural Nicaraguan schoolchildren.

Background: We aimed to investigate the effectiveness of using minimally trained community health workers (CHW) to screen schoolchildren in rural Nicaragua for hearing loss using a tablet-based audiometric system integrated with asynchronous telehealth evaluations and mobile health (mHealth) appointment reminders.

Methods: A population-based survey was conducted using community health workers (CHWs) to perform tablet-based audiometry, asynchronous telehealth evaluations, and mHealth reminders to screen 3398 school children (7-9 years of age) in 92 rural Nicaraguan communities. The accuracy of screening, test duration, testing efficiency, telehealth data validity, and compliance with recommended clinic visits were analyzed.

Headache in Pregnancy.

Headache is a common symptom in pregnancy. The differential diagnosis for headache in pregnancy is broad and includes conditions that range in acuity and severity. Most headaches in pregnancy are migraine or tension-type headaches.

Test-Retest repeatability of automated threshold audiometry in Nicaraguan schoolchildren.

Objective: Automated threshold audiometry (ATA) could increase access to paediatric hearing assessment in low- and middle-income countries, but few studies have evaluated test-retest repeatability of ATA in children. This study aims to analyse test-retest repeatability of ATA and to identify factors that affect the reliability of this method.

Design: ATA was performed twice in a cohort of Nicaraguan schoolchildren.

Preoperative Criteria Predict Operative Time Variability Within Tympanoplasty Procedures.

Objective: To identify preoperative patient and surgical parameters that predict operative time variability within tympanoplasty current procedural terminology (CPT) codes.

Study Design: Retrospective.

Setting: Tertiary referral center.

Developmental Anatomy of the Eustachian Tube: Implications for Balloon Dilation.

Objective: To describe the developmental anatomy of the eustachian tube (ET) and its relationship to surrounding structures on computed tomography.

Study Design: Case series with chart review.

Setting: A tertiary care hospital.

Reliability of Tablet-based Hearing Testing in Nicaraguan Schoolchildren: A Detailed Analysis.

Objective: Determine whether an electronic tablet-based Wireless Automated Hearing-Test System can perform high-quality audiometry to assess schoolchildren for hearing loss in the field in Nicaragua.

Study Design: Cross-sectional.

Setting: A school and hospital-based audiology clinic in Jinotega, Nicaragua.

Cost-effectiveness of CI in developing countries.

Purpose Of Review: Cost-effectiveness of cochlear implants is a major concern for expanding these services to low-income and middle-income developing countries.

Recent Findings: Recent studies have applied appropriate methodology to make determination of cost-effectiveness for cochlear implants in developing countries. In addition, important parameters that effect cost-effectiveness have been reviewed in a systematic way.

Practical Guidelines for High-Resolution Epigenomic Profiling of Nucleosomal Histones in Postmortem Human Brain Tissue.

Background: The nervous system may include more than 100 residue-specific posttranslational modifications of histones forming the nucleosome core that are often regulated in cell-type-specific manner. On a genome-wide scale, some of the histone posttranslational modification landscapes show significant overlap with the genetic risk architecture for several psychiatric disorders, fueling PsychENCODE and other large-scale efforts to comprehensively map neuronal and nonneuronal epigenomes in hundreds of specimens. However, practical guidelines for efficient generation of histone chromatin immunoprecipitation followed by deep sequencing (ChIP-seq) datasets from postmortem brains are needed.
