Introduction: Randomized controlled trials found that fetoscopic endoluminal tracheal occlusion (FETO) resulted in increased fetal lung volume and improved survival for infants with isolated, severe left-sided congenital diaphragmatic hernia (CDH). The delivery room resuscitation of these infants is particularly unique, and the specific delivery room events are largely unknown. The objective of this study was to compare the delivery room resuscitation of infants treated with FETO to standard of care (SOC) and describe lessons learned.

Objectives: Intracapsular tonsillectomy and adenoidectomy (iTA) has become a popular alternative to extracapsular tonsillectomy and adenoidectomy (TT) for the treatment of pediatric obstructive sleep apnea (OSA) due to improved recovery and fewer complications. The objective of this study was to compare surgical recovery and impact on OSA of iTA versus TT in patients with Trisomy 21 (T21).

Methods: This is a case series with chart review of all T21 patients who underwent iTA or TT at our institution between July 1, 2015 and August 15, 2022.

Purpose: Mandibular distraction osteogenesis (MDO) may improve airway grade in patients with Robin Sequence (RS), but little is known about the response of the oropharyngeal airway to the distraction process in cases of tongue base obstruction (TBAO). This study used drug-induced sleep endoscopy (DISE) to evaluate the impact of MDO on the oropharynx.

Methods: RS patients with severe obstructive sleep apnea (OSA) were prospectively enrolled, and underwent DISE prior to MDO, and at the time of distractor removal.

Objectives: To describe the use of customized and custom tracheostomies at our institution, and to identify trends in patient presentation and tracheostomy design.

Methods: A retrospective review was conducted for patients at our institution for whom a customized or custom tracheostomy tube was ordered between January 2011 and July 2021. Customized tracheostomy tubes allow for a small selection of alterations to trach design, such as cuff length and flange type.

Paper-based microfluidic devices, also known as microPADs, are an emerging analytical platform with the potential to improve point-of-care diagnostics. MicroPADs are fabricated by patterning hydrophobic inks onto sheets of paper to create hydrophilic channels and test zones. One of the main advantages of microPADs is that they are inexpensive and simple to fabricate, making them accessible even to researchers with limited budgets or no prior fabrication expertise.

Background And Aims: In 2015, Georgia began a hepatitis C virus (HCV) elimination programme. Although screening programmes have been decentralized for high-risk groups, viraemic testing remains a bottleneck for people who inject drugs. Here, we describe two models of viraemic testing that aimed to address this gap.

Introduction: To achieve the elimination of hepatitis C virus (HCV), substantial scale-up in access to testing and treatment is needed. This will require innovation and simplification of the care pathway, through decentralisation of testing and treatment to primary care settings and task-shifting to non-specialists. The objective of this study was to evaluate the feasibility and effectiveness of decentralisation of HCV testing and treatment using rapid diagnostic tests (RDTs) in primary healthcare clinics (PHCs) among high-risk populations, with referral of seropositive patients for confirmatory viral load testing and treatment.

Background And Aims: India has a significant burden of hepatitis C virus (HCV) infection and has committed to achieving national elimination by 2030. This will require a substantial scale-up in testing and treatment. The "HEAD-Start Project Delhi" aimed to enhance HCV diagnosis and treatment pathways among the general population.

was isolated from the Salish Sea (Puget Sound) ecosystem, including samples of marine and fresh water, and wildlife dependent on this environment. isolates were assessed for phenotypic and genotypic resistance to antibiotics. A total of 305 isolates was characterized from samples collected from: marine water obtained in four quadrants of the Salish Sea; select locations near beaches; fresh water from streams near marine beaches; and fecal samples from harbor porpoises (), harbor seals (), river otters (), and English sole ().

Background: , a multidrug-resistant yeast, can spread rapidly in ventilator-capable skilled-nursing facilities (vSNFs) and long-term acute care hospitals (LTACHs). In 2018, a laboratory serving LTACHs in southern California began identifying species of that were detected in urine specimens to enhance surveillance of , and was identified in February 2019 in a patient in an Orange County (OC), California, LTACH. Further investigation identified at 3 associated facilities.

Adenotonsillectomy is one of the most common surgical procedures performed by otolaryngologists. It is vital that surgeons are aware of the risks in performing this surgery especially during the COVID-19 pandemic and in children with hematologic disorders. In this review we describe common hematologic disorders often noted in pediatric patients undergoing this procedure, as well as proper screening and management of these patients.

Congenital external auditory canal stenosis (EACS) is a spectrum of abnormalities affecting the external and middle ear. We report a 6 year-old patient with EACS affecting the lateral fibrocartilaginous canal that was successfully repaired. This patient highlights a variant of EACS characterized by lateral soft tissue narrowing with normal osseous development.

Recurrent Respiratory Papillomatosis (RRP) is a rare disease of the aerodigestive tract caused by the Human Papilloma Virus (HPV) that manifests as profoundly altered phonatory and upper respiratory anatomy. Current therapies are primarily symptomatic; enhanced insight regarding disease-specific biology of RRP is critical to improved therapeutics for this challenging population. Multiplex PCR was performed on oral rinses collected from twenty-three patients with adult-onset RRP every three months for one year.

Objectives: To compare the diagnostic performance of the Hum Test against the Weber Test using pure tone audiometry (PTA) as the "gold standard" comparator.

Methods: 29 participants with normal hearing of ages 18 to 35 without any history of hearing abnormalities or otologic conditions were enrolled. Subjects underwent three tests (Hum Test, Weber Test, and PTA) across two conditions: with an ear plug in one ear (side randomized) and without ear plugs.

Article Synopsis
  • The study aimed to create a model to understand how concurrent chemoradiation therapy (CCRT) for oropharyngeal cancer affects tongue function and structure, as current research methods are lacking.
  • Twenty-one male rata were divided into three groups to assess tongue strength and muscle changes after receiving CCRT or no treatment; results were collected at 2 weeks and 5 months.
  • Findings showed significant decreases in tongue strength and movement after CCRT, but no observable changes in muscle collagen content, indicating other factors might be responsible for the dysfunction observed.

Objectives/hypothesis: To determine oral human papilloma virus (HPV) colonization in patients with adult-onset recurrent respiratory papillomatosis (AO-RRP) and their long-term partners.

Study Design: Prospective, cohort study

Methods: Patients with pathology-confirmed AO-RRP and a small cohort of their long-term partners were subjected to a standardized oral rinse and swab protocol to obtain oral epithelial cells. DNA from these samples was extracted and subjected to both qualitative analyses via multiplex polymerase chain reaction as well as to a commercially available linear array assay for the determination of specific HPV subtypes.
