Simulation-based workshop for emergency preparedness in otolaryngology.

Objectives: This study aimed to evaluate the outcomes of a hands-on simulation-based course with emphasis on procedural techniques, clinical reasoning, and communication skills developed to improve junior Otolaryngology - Head and Neck Surgery (OHNS) residents' preparedness in managing otolaryngologic emergencies.

Methods: Junior OHNS residents and faculty from residency programs in California, Nevada, and Arizona participated in this workshop in 2020 and 2021. The stations featured airway management techniques, ultrasound-guided needle aspiration, nasoseptal hematoma evacuation, and facial fracture repair using various models and cadavers.

Current and Future Developments in Wound Healing.

Poor wound healing on the face and neck can lead to significant morbidity and dissatisfaction in facial plastic surgery. With current advances in wound healing management and commercially available biologic and tissue-engineered products, there are several options available to optimize acute wound healing and treat delayed or chronic wounds. This article summarizes some of the key principals and recent developments in wound healing research in addition to potential future advancements in the field of soft tissue wound healing.

Reducing Risks for Local Skin Flap Failure.

Local tissue flaps are a fundamental technique in cutaneous reconstruction. Reducing the risk of flap failure is of critical importance. The intrinsic vascularity of a flap is the most important determinant of success.

Reducing Risks of Facial Scarring.

Risk factors for the formation of facial scars include skin type, ethnicity, scar location, and certain medical conditions that contribute to poor or delayed healing. Risk of scar can be reduced with appropriate surgical planning, including proper placement and design of incisions, meticulous skin closure, aseptic technique, and wound care to improve healing. Common pathologic scars include hypertrophic scars and keloid scars, each of which has unique approaches to surgical revision and medical treatment due to their respective risks of recurrence.

Reducing Risks for Poor Surgical Wound Healing.

This review summarizes common risk factors for poor surgical healing on the face and neck and a generalized approach to treating a delayed healing wound. During the preoperative evaluation patients should be screened for prior irradiation, cigarette or e-cigarette use, chronic steroid use, alcoholism, diabetes, malnutrition, and other chronic medical conditions and medications. Despite the surgeon's best efforts to prevent poor surgical healing, some wounds may display signs of persistent inflammation.

Effects of Altering Magnesium Metal Surfaces on Degradation In Vitro and In Vivo during Peripheral Nerve Regeneration.

In vivo use of biodegradable magnesium (Mg) metal can be plagued by too rapid a degradation rate that removes metal support before physiological function is repaired. To advance the use of Mg biomedical implants, the degradation rate may need to be adjusted. We previously demonstrated that pure Mg filaments used in a nerve repair scaffold were compatible with regenerating peripheral nerve tissues, reduced inflammation, and improved axonal numbers across a short-but not long-gap in sciatic nerves in rats.

Change in surgeon for revision rhinoplasty: The impact of patient demographics and surgical technique on patient retention.

Objectives: A subset of patients who require revision rhinoplasty will change surgeons for their second procedure. We sought to investigate the rate of surgeon change and identify associated predictors using a population-based, ambulatory surgery database.

Methods/study Design: In this retrospective review, 9172 rhinoplasty procedures over a 5-year period were analyzed using the Healthcare Cost and Utilization Project (HCUP) Florida State Ambulatory Surgery and Services Database (SASD).

Three Rare Concurrent Complications of Tertiary Hyperparathyroidism: Maxillary Brown Tumor, Uremic Leontiasis Ossea, and Hungry Bone Syndrome.

A 48-year-old woman in her 40's with end-stage renal disease and tertiary hyperparathyroidism (HPT) presented for a rapidly progressive maxillary tumor. Initial workup was notable for elevated intact parathyroid hormone (PTH) and diffuse thickening of skull and facial bones on computed tomography, and maxillary tumor biopsy with multinucleated giant cells. She underwent subtotal parathyroidectomy (with removal of a parathyroid adenoma and 2 hyperplastic glands) and partial resection of maxillary brown tumor.

Navigating telemedicine for facial trauma during the COVID-19 pandemic.

Importance: The COVID-19 pandemic is changing how health care providers practice. As some telemedicine and telecommunication support tools have been incorporated into the otolaryngology practice in response to safety and access demands, it is essential to review how these tools and services can help facilitate facial trauma evaluation during a time when clinical resources are limited.

Objective: To review applications of telemedicine for the evaluation of facial trauma to better direct utilization of these methods and technologies during times of limited access to clinical resources such as the COVID-19 pandemic.

Electric scooter craniofacial trauma.

Objective: The use of standing electronic scooters associated with micromobility applications (e-scooters) has risen nationally. The aim of this study was to obtain a detailed view of soft tissue and bony craniofacial injury associated with e-scooter-related trauma.

Methods: Single-institution retrospective case series of patients presenting to a level 1 trauma center emergency department or trauma unit with documented e-scooter-related craniofacial injury.

Location Propensity for Keloids in the Head and Neck.

The difficulty associated with concealing keloids located in the face and neck regions often results in disfigurement and psychological stress for patients. The purpose of this review is to determine if specific regions on the head and neck have a greater propensity to develop keloids to alert the facial plastic surgeon of regional keloid risk. PubMed, Ovid, Cochrane, and Embase computerized searches were performed through January 2020.

Dermabrasion for Scars and Wire Loop Electrocautery for Rhinophyma.

Dermabrasion and wire loop electrocautery are controlled scalpel-less procedures to remove superficial skin layers to treat dermal surface irregularities. Their postprocedure healing involves healing by secondary intention. The purpose of this paper is to discuss the use of diamond fraise dermabrasion to improve scars and the use of wire loop electrocautery to treat rhinophyma surface irregularities.

Embedding magnesium metallic particles in polycaprolactone nanofiber mesh improves applicability for biomedical applications.

Magnesium (Mg) metal is of great interest in biomedical applications, especially in tissue engineering. Mg exhibits excellent in vivo biocompatibility, biodegradability and, during degradation, releases Mg ions (Mg) with the potential to improve tissue repair. We used electrospinning technology to incorporate Mg particles into nanofibers.

Existing blood transcriptional classifiers accurately discriminate active tuberculosis from latent infection in individuals from south India.

Several studies have identified blood transcriptomic signatures that can distinguish active from latent Tuberculosis (TB). The purpose of this study was to assess how well these existing gene profiles classify TB disease in a South Indian population. RNA sequencing was performed on whole blood PAXgene samples collected from 28 TB patients and 16 latently TB infected (LTBI) subjects enrolled as part of an ongoing household contact study.

Strains of Mycobacterium tuberculosis transmitting infection in Brazilian households and those associated with community transmission of tuberculosis.

Molecular epidemiologic studies have shown that the dynamics of tuberculosis transmission varies geographically. We sought to determine which strains of Mycobacterium tuberculosis (MTB) were infecting household contacts (HHC), and which were causing clusters of tuberculosis (TB) disease in Vitoria-ES, Brazil. A total of 741 households contacts (445 TST +) and 139 index cases were characterized according to the proportion of contacts in each household that had a tuberculin skin test positive: low (LT) (≤40% TST+), high (HT) (≥70% TST+) and (40-70% TST+) intermediate (IT) transmission.
