Case Report: The effect of automated manual lymphatic drainage therapy on lymphatic contractility in 4 distinct cases.

Introduction: Automated manual lymphatic drainage therapy (AMLDT) is available for home use in the form of a pneumatic mat of 16 pressurized air channels that inflate and deflate to mimic the stretch and release action of manual lymphatic drainage therapy. Four cases (a patient with complex regional pain syndrome and lymphedema, a healthy patient, a breast cancer survivor with chronic pain, and a patient with a history of abdominal surgery) underwent near-infrared fluorescence lymphatic imaging (NIRFLI) with AMLDT to evaluate the effect of AMLDT on lymphatic pumping and pain.

Methods: Each patient received 32-36 injections of 25 μg indocyanine green (ICG) on the anterior and posterior sides of their body and underwent 1 h of NIRFLI to assess the drainage of ICG laden lymph toward regional nodal basins at baseline.

Synchronous Presentation of Right Parotid Branchial Cleft Cyst and Left Neck HPV-Associated Cystic Metastatic Squamous Cell Carcinoma: A Diagnostic Quandary.

Branchial cleft cyst arising within the parotid space is considered an extremely rare phenomenon. In contrast, cystic squamous cell carcinoma in the lateral neck is not an uncommon presentation of HPV-related head and neck cancer. Although they have singly been narrated in literature, simultaneous expression of these anomalies has yet to be reported.

Infected Ruptured Parathyroid Cyst Presenting with Hypercalcemia and Airway Obstruction: A Case Report.

Parathyroid cysts (PC) are infrequently encountered and characterize less than 1% of all head and neck masses. When present, PCs may present as a palpable neck mass and lead to hypercalcemia and rarely respiratory depression. Furthermore, the diagnostics of PCs is difficult as they can masquerade as a thyroid or mediastinal mass given their proximity.

NUT Carcinoma of the Submandibular Gland: A Case at This Uncommon Site with Review of the Literature.

Nuclear protein in testis (NUT) carcinoma is a rare, highly aggressive, undifferentiated carcinoma that harbors a characteristic rearrangement of the NUTM1 gene. The majority arise in adolescents and young adults especially from the midline structures of the thorax, head, and neck. Until the present, there have only been three reported cases of NUT carcinoma of the submandibular gland, two of which were reported in children and another one in an adult from Korea.

Povidone-iodine solution as SARS-CoV-2 prophylaxis for procedures of the upper aerodigestive tract a theoretical framework.

Background: The COVID-19 pandemic has raised concerns of inadvertent SARS-CoV-2 transmission to healthcare workers during routine procedures of the aerodigestive tract in asymptomatic COVID-19 patients. Current efforts to mitigate this risk focus on Personal Protective Equipment, including high-efficiency filtration as well as other measures. Because the reservoir for SARS-CoV-2 shedding is in the nasopharynx and nasal and oral cavities, the application of viricidal agents to these surfaces may reduce virus burden.

4D-CT facilitates focused parathyroidectomy in patients with primary hyperparathyroidism by maintaining a high negative-predictive value for uninvolved quadrants.

Introduction: Improved preoperative localization facilitates minimally invasive parathyroidectomy for removal of parathyroid lesions therefore preventing an invasive bilateral neck exploration. As 4D-CT has emerged, its high specificity has helped with preoperative parathyroid lesion localization. A high negative predictive value (NPV) would serve to further confirm parathyroid lesion localization and limit unnecessary surgical exploration.

Desmoplastic Small Round Cell Tumor of Parotid Gland: A Rare Entity With Diagnostic Challenge.

Desmoplastic small round cell tumor (DSRCT) is a rare malignant mesenchymal neoplasm that typically affects young patients and presents as large intraabdominal masses. We report a rare case of parotid gland DSRCT in a 38-year-old man. The tumor cells were large sized and form irregular nests embedded in abundant desmoplastic stroma.

Longitudinal effects of a novel advanced pneumatic compression device on patient-reported outcomes in the management of cancer-related head and neck lymphedema: A preliminary report.

Background: Head and neck cancer (HNC) survivors experience head and neck lymphedema (HNL), which requires treatment to prevent morbidity. We explore the self-reported outcomes and satisfaction of patients with HNC receiving treatment for HNL with an advanced pneumatic compression device (APCD).

Methods: HNC survivors (n = 205) prescribed with an at-home Flexitouch head and neck APCD completed pretreatment and posttreatment self-reported assessments addressing efficacy, function, and symptoms.

Assessing lymphatic route of CSF outflow and peripheral lymphatic contractile activity during head-down tilt using near-infrared fluorescence imaging.

Evidence overwhelmingly suggests that the lymphatics play a critical role in the clearance of cerebrospinal fluid (CSF) from the cranial space. Impairment of CSF outflow into the lymphatics is associated with a number of pathological conditions including spaceflight-associated neuro-ocular syndrome (SANS), a problem that limits long-duration spaceflight. We used near-infrared fluorescence lymphatic imaging (NIRFLI) to dynamically visualize the deep lymphatic drainage pathways shared by CSF outflow and disrupted during head-down tilt (HDT), a method used to mimic the cephalad fluid shift that occurs in microgravity.

Head and Neck Lymphedema: Treatment Response to Single and Multiple Sessions of Advanced Pneumatic Compression Therapy.

Ten head and neck cancer survivors diagnosed with head and neck lymphedema (HNL) were imaged using near-infrared fluorescence lymphatic imaging (NIRFLI) prior to and immediately after an initial advance pneumatic compression device treatment and again after 2 weeks of daily at-home use. Images assessed the impact of pneumatic compression therapy on lymphatic drainage. Facial composite measurement scores assessed reduction/increase in external swelling, and survey results were obtained.

Planned Gamma Knife Boost After Chemoradiotherapy for Selected Sinonasal and Nasopharyngeal Cancers.

Objective: To determine the feasibility of a Gamma Knife boost after intensity-modulated radiation therapy in combination with multimodal therapy in patients with nasopharyngeal carcinoma and sinonasal malignancies with skull base or cavernous sinus involvement.

Methods: Nine patients were treated with intensity-modulated radiation therapy followed by a Gamma Knife boost. In one case Gamma Knife was given as salvage treatment after resection.

Morphoproteomics, E6/E7 in-situ hybridization, and biomedical analytics define the etiopathogenesis of HPV-associated oropharyngeal carcinoma and provide targeted therapeutic options.

Background: Human papillomavirus (HPV) has been identified as an etiopathogenetic factor in oropharyngeal squamous cell carcinoma. The HPV E6 and E7 oncogenes are instrumental in promoting proliferation and blocking differentiation leading to tumorigenesis. Although surgical intervention can remove such tumors, the potential for an etiologic field effect with recurrent disease is real.

Post-operative therapy following transoral robotic surgery for unknown primary cancers of the head and neck.

Objectives: Our primary objective is to describe the post- operative management in patients with an unknown primary squamous cell carcinoma of the head and neck (HNSCC) treated with trans-oral robotic surgery (TORS).

Materials & Methods: We conducted a retrospective multi-institutional case series including all patients diagnosed with an unknown primary HNSCC who underwent TORS to identify the primary site from January 1, 2010 to June 30, 2016. We excluded those with recurrent disease, ≤6months of follow up from TORS, previous history of radiation therapy (RT) to the head and neck, or evidence of primary tumor site based on previous biopsies.

Mucoepidermoid carcinoma post-radioactive iodine treatment of papillary thyroid carcinoma: unique presentation and putative etiologic association.

We report the development of mucoepidermoid carcinomas of the parotid gland in 2 adult patients after a relatively short duration of radioactive iodine (RAI) treatment of papillary thyroid carcinoma. Both instances, together with those previously reported, underscore the selective nature of the mucoepidermoid carcinoma phenotype development in patients with papillary thyroid carcinoma as a consequence of RAI treatment. Efforts to alleviate salivary pathophysiologic damage by RAI in these patients are warranted.

Longitudinal monitoring of the head and neck lymphatics in response to surgery and radiation.

Background: The lymphatic vasculature provides a route for cancer metastases, and its dysfunction after cancer treatment can result in lymphedema. However, changes in the lymphatics before, during, and after surgery and radiation remain unclear.

Methods: Near-infrared fluorescence lymphatic imaging was performed before and after lymph node dissection and fractionated radiotherapy to assess changes in external lymphatic function.

Comparing success rates of anesthesia providers versus trauma surgeons in their use of palpation to identify the cricothyroid membrane in female subjects: a prospective observational study.

Purpose: The primary aim of this study was to compare the success rates of anesthesia providers vs trauma surgeons in their use of palpation to identify the cricothyroid membrane (CTM). The secondary aim was to explore whether prior training and experience performing surgical airways affected the success rates for identifying the CTM.

Methods: Four female adults participated in this prospective observational study.

The effects of anesthesia on the morphoproteomic expression of head and neck squamous cell carcinoma: a pilot study.

The prognosis and disease-free survival rates for head and neck squamous cell carcinoma (HNSCC) have remained relatively stagnant for the last several decades. Moreover, as is the case with other malignancies, locoregional recurrence and distant metastasis are all too common even after seemingly successful oncologic surgery and adjuvant therapy. Recently, increased focus has been placed on understanding the influence of perioperative factors on tumor cell behavior and surgical outcomes.
