Hypopharyngeal Amyloidosis: A Rare Cause of Dysphagia.

Amyloidosis localized to the head and neck most commonly affects the laryngo-tracheobronchial tree or tongue. It rarely affects the hypopharynx, with only 3 cases reported in literature. All of these cases describe females presenting with hypopharyngeal amyloid masses and associated multiple myeloma or monoclonal gammopathy of undetermined significance.

A Comparison of Therapy Adherence for Vocal Fold Atrophy and Chronic Cough.

Introduction: Therapy is a common treatment for dysphonia attributable to vocal fold atrophy and chronic cough with the goal of decreasing procedural intervention. We compared the rates of therapy adherence and the factors associated with therapy adherence across groups.

Methods: Retrospective chart review at a single institution since 2019.

Revision Tracheotomy Complicated by History of Follicular B-Cell Lymphoma.

This case report presents a 65-year-old woman with multiple complications during a revision tracheotomy including subcutaneous emphysema and a pneumothorax. Management of her airway was complicated by a history of recurrent follicular B-cell lymphoma associated with extensive cervical lymphadenopathy. We detail the importance of heightened clinical awareness and the use of intraoperative safety adjuncts when performing revision tracheostomies.

Readmission and reoperation after laryngeal dilation in children: NSQIP-P analysis.

Objective: To identify specific comorbidities and their relationship to complications in children who underwent laryngeal dilation, specifically comparing children with tracheostomy versus no tracheostomy as well as differences in outcomes between age groups.

Methods: Retrospective study analyzing data collected in the American College of Surgeons National Surgical Improvement - Pediatric Database (2015-2018). Patients were selected using Current Procedural Terminology code 31528.

Proposed ultrasound algorithm to differentiate thyroglossal duct and dermoid cysts.

Objective: 1) To assess reproducibility of the previously established SIST score. 2) To determine inter-observer agreement in using ultrasound (US) characteristics to differentiate thyroglossal duct cyst (TGDC) from dermoid cysts (DC) 3) Improve the method used to pre-operatively differentiate TGDC from DC.

Study Design: Retrospective chart review.

Gaps in Training: Misunderstandings of Airway Management in Medical Students and Internal Medicine Residents.

Objectives: (1) Evaluate baseline airway knowledge of medical students (MSs) and internal medicine (IM) residents. (2) Improve MS and IM resident understanding of airway anatomy, general tracheostomy and laryngectomy care, and management of airway emergencies.

Methods: A before-and-after survey study was carried out over a single academic year.

Presurgical induction chemotherapy for squamous cell carcinoma of the tonsil.

Objectives/hypothesis: The indications for and efficacy of induction chemotherapy in the management of squamous cell carcinoma of the head and neck is controversial. With the advent of human papillomavirus (HPV)-related cancers, survival has improved significantly. Here we present a group of patients with tonsil cancer treated with induction chemotherapy followed by surgery.

Application of infrared-based molecular imaging to a mouse model with head and neck cancer.

Background: This study investigated whether near infrared (NIR) or visible fluorescent molecular imaging produced a better representation of a mouse model with head and neck squamous cell carcinoma (HNSCC). Additionally, the study explored whether epidermal growth factor receptor (EGFR)-targeted probes could play an important role in the diagnosis of HNSCC.

Methods: An orthotopic mouse model of HNSCC labeled with the NIR fluorophore, infrared fluorescent protein (iRFP), was developed and monitored noninvasively in real time.

Independence of brain and trunk temperature during hypothermic preconditioning in rats.

Unlabelled: Hypothermic preconditioning is rapid cooling and warming to induce tolerance to ischemia. The purpose of the study was to examine differences in brain and trunk temperature during hypothermic preconditioning.

Methods: Rats (n=18) were implanted with telemetric probes for simultaneous measure of brain and trunk temperature.

Infrared imaging of trauma patients for detection of acute compartment syndrome of the leg.

Objective: Early compartment syndrome is difficult to diagnose, and a delay in the diagnosis can result in amputation or death. Our objective was to explore the potential of infrared imaging, a portable and noninvasive technology, for detecting compartment syndrome in the legs of patients with multiple trauma. We hypothesized that development of compartment syndrome is associated with a reduction in surface temperature in the involved leg and that the temperature reduction can be detected by infrared imaging.
