This study presents the design of efficient wireless power distribution systems based on resonant inductive arrays. The authors show how to use multi‐resonator arrays to charge and power up several electric devices in parallel, with nearly constant transmitted power, and using a single power source. Their single‐source wireless power transmission clusters, for instance, are shown to provide free positioning at better power efficiency than previous solutions. They provide analysis, simulation, and measurement performance of their multi‐resonator arrays, they compare them with other types of inductive arrays employed into different schemes (multi‐coil inductive links, overlapping and non‐overlapping links), and they show the advantage of their strategy over previous solutions. The presented wireless power distribution systems improve power transmission efficiency (PTE) in free positioning by as much as 30%. The measured results show that their multi‐resonator arrays present significant advantages: (i) they allow multiple charging zones from a single power source; (ii) they provide free positioning with strictly uniform power delivered to the load; and (iii) they provide superior efficiency through a built‐in power localization mechanism, which is not available in other solutions. The PTE of the multi‐resonator array in single‐receiver and multi‐receiver configurations outperformed previous solutions by 26% and 12%, respectively. [ABSTRACT FROM AUTHOR]

Objective: The urgent nature of head and neck cancer referrals often results in overbooked schedules, access delays, and patient, physician, and staff dissatisfaction. The goal of this study is to examine how incorporation of associate providers (APs) into a head and neck tumor clinic (HNTC) can improve access.Methods: Scheduling data for the Dartmouth-Hitchcock HNTC 2 years prior (January 2011 to December 2012) and 2 years subsequent (January 2013 to December 2014) to program initiation were abstracted, including number of new patients seen per month, third available for new and established patients, overbooked hours, surgeon productivity, and patient satisfaction scores.Results: New patients seen per month increased from 44 ± 4 to 60 ± 5 (P < .001). Third available for new patients decreased from 56 ± 4 to 27 ± 2 days and from 43 ± 3 to 35 ± 2 days for follow-ups (P < .001). Overbooked hours decreased from 14.7 ± 3.1 to 8.6 ± 1.7 hours (P < .001). Surgeon productivity remained stable (109% ± 11% vs 113% ± 6%, P = .56). Patient satisfaction in seeing APs versus surgeons was comparable (94 ± 2 vs 94 ± 3, P = .79).Discussion: Incorporation of APs into the HNTC increases the number of new patients seen by the surgeon, decreases wait times for all appointments, and decreases overbooking while maintaining patient satisfaction and surgeon productivity.Implications For Practice: AP incorporation significantly improves access to head and neck surgical services. With improved access, new cancer patients could start treatment sooner, potentially affecting outcome. [ABSTRACT FROM AUTHOR]

Objective: The dramatic rise in oropharyngeal squamous cell carcinoma associated with the human papilloma virus (HPV) has brought significant change to the interaction between patients and head and neck oncologists. HPV-induced cancers are generally the result of elements from the patient's sexual history, and otolaryngologists are generally less experienced than primary care physicians in addressing patient questions relating to sexual history and practices. This article addresses questions commonly posed by patients relating to HPV-induced head and neck cancers, issues related to HPV vaccination, and surveillance of HPV-related lesions. Supporting data are provided such that physicians may be better equipped to sufficiently address patient queries on this topic.Data Sources: Available peer-reviewed literature and clinical practice guidelines.Review Methods: Assessment and discussion of specific topics by authors selected from the Head and Neck Surgery Education Committee of the American Academy of Otolaryngology-Head and Neck Surgery Foundation.Results: An educational "miniseminar" resulted in a notable increase in attendee knowledge and comfort regarding oropharyngeal squamous cell carcinoma counseling for patients in the setting of HPV-positive disease.Conclusions and Implications For Practice: The dramatic increase in HPV-associated head and neck cancers has resulted in a changed paradigm of the physician-patient interaction. Care providers in today's environment must be prepared to counsel patients regarding sexually transmitted diseases and high-risk sexual behaviors. Examination of the existing data provides the foundation with which to construct a framework in which physicians can effectively communicate information and recommendations as they pertain to HPV-related carcinoma.

Program Description: Neck dissection continues to be an integral part of surgical treatment of head and neck squamous cell carcinoma (HNSCC). The operation has evolved significantly since first described by Crile and others more than 100 years ago. With the development of more precise imaging modalities, chemoradiation treatment protocols, and transoral laser (TLM) and robotic (TORS) surgery, it is important to reexamine guidelines for management of the neck. This miniseminar will focus on several relevant topics pertaining to treatment of the neck in HNSCC: 1) The role of imaging in planning treatment of the neck will be discussed. Pre‐treatment imaging with PET, CT, and MRI can yield valuable information regarding subclinical neck metastases and may help in treatment planning, particularly for T1 and T2 primary tumors. The timing and optimal modality for post‐chemoradiation imaging remains controversial. 2) The advantages and disadvantages for upfront neck dissection for small and unknown primary HNSCC will be addressed. Elective neck dissection vs radiation vs observation for clinically negative necks will be discussed. 3) Management of the neck in conjunction with TLM/TORS will be examined. With increasing use of TLM/TORS for surgical management of HNSCC, it is essential that the neck is treated appropriately. Guidelines for neck dissection in conjunction with TLM/TORS will be outlined. 4) Paradigms for management of the neck following chemoradiation continue to evolve. Chemoradiation protocols for HNSCC are effective in eradicating advanced nodal disease as well as the primary tumor. Thus, the use of planned neck dissection for N2 and N3 disease following completion of chemoradiation is giving way to the use of salvage neck dissection. Also, concepts have changed toward the use of more limited neck dissections. Finally, challenging cases involving management of neck disease will be presented to the panel of experts, for discussion and audience participation. Educational Objectives: 1) Understand the role of imaging in planning treatment of the neck. 2) Understand how to manage the neck in conjunction with TLM/TORS. 3) Understand how paradigms for management of the neck following chemoradiation have evolved.

Program Description: Human papillomavirus (HPV)–related oropharyngeal cancer is now recognized as a clinically distinct entity, and data describing the nature of the epidemic, optimal treatment strategies, and survival outcomes are rapidly developing. Our patients are asking pertinent questions about HPV transmission, the role of vaccination, and monitoring recommendations. This miniseminar will update practitioners on the accuracy of testing, how to counsel patients and families regarding the nature of HPV infection (risk and transmissibility), vaccination, the management of benign lesions, and surveillance. This panel will appeal broadly to trainees, general otolaryngologists, and head and neck surgical oncologists. Educational Objectives: (1) Advise patients and partners regarding HPV infection and transmission. (2) List the Centers for Disease Control and Prevention recommendations for HPV vaccination. (3) Develop a surveillance plan for patients with HPV and their families. [ABSTRACT FROM AUTHOR]
