Rattled: Analysis of Facial Trauma Among Toddlers.

OBJECTIVE: The aim of this study was to determine the national incidence of facial trauma among toddlers and delineate patterns of injury and their causes. METHODS: A retrospective review was designed to explore patterns of maxillofacial trauma within toddler-aged children using the National Electronic Injury Surveillance System from the Consumer Product Safety Commission. The database was searched for emergency department visits involving facial trauma sustained by children 12 months through 3 years of age from 2010 through 2014 and analyzed for patient demographics, primary diagnosis, and associated products/activities. Subset analyses were performed between age groups to determine the relationship between causes of injury and age using extrapolated national incidences. RESULTS: A sample of 45,249 patients extrapolated to an estimated 1.3 million emergency department visits for facial trauma in toddlers from 2010 to 2014, averaging 260,000 annually. Injuries involving foreign bodies and fractures had a higher incidence in toddlers 2 years or older, and fractures comprised fewer than 1% of facial injuries in any age group. Furniture was the most common source of trauma overall, with a higher frequency among toddlers aged 12 to 17 months. Trauma in the setting of sports was more common in toddlers aged 3 years. CONCLUSIONS: The low incidence of facial fractures further supports recommendations against routine imaging in toddler facial trauma and suggests that more focus should be placed on investigating for concurrent traumas and soft tissue injuries where fractures are involved. Our findings highlight prevention opportunities, particularly in furniture-related injuries for toddlers aged 12 to 17 months and sports-related traumas in toddlers aged 3 years. Our study also suggests restricting certain toys from 3-year-old toddlers to decrease the risk of aspiration.

Oncologic Safety of Close Margins in Patients With Low- to Intermediate-Grade Major Salivary Gland Carcinoma.

Importance: Postoperative radiation therapy for close surgical margins in low- to intermediate-grade salivary carcinomas lacks multi-institutional supportive evidence. Objective: To evaluate the oncologic outcomes for low- and intermediate-grade salivary carcinomas with close and positive margins. Design, Setting, and Participants: The American Head and Neck Society Salivary Gland Section conducted a retrospective cohort study from 2010 to 2019 at 41 centers. Margins were classified as R0 (negative), R1 (microscopically positive), or R2 (macroscopically positive). R0 margins were subclassified into clear (>1 mm) or close (≤1 mm). Data analysis was performed from June to October 2023. Main Outcomes and Measures: Main outcomes were risk factors for local recurrence. Results: A total of 865 patients (median [IQR] age at surgery, 56 [43-66] years; 553 female individuals [64%] and 312 male individuals [36%]) were included. Of these, 801 (93%) had parotid carcinoma and 64 (7%) had submandibular gland carcinoma, and 748 (86%) had low-grade tumors and 117 (14%) had intermediate-grade tumors, with the following surgical margins: R0 in 673 (78%), R1 in 168 (19%), and R2 in 24 (3%). Close margins were found in 395 of 499 patients with R0 margins (79%), for whom margin distances were measured. A total of 305 patients (35%) underwent postoperative radiation therapy. Of all 865 patients, 35 (4%) had local recurrence with a median (IQR) follow-up of 35.3 (13.9-59.1) months. In patients with close margins as the sole risk factor for recurrence, the local recurrence rates were similar between those who underwent postoperative radiation therapy (0 of 46) or observation (4 of 165 [2%]). Patients with clear margins (n = 104) had no recurrences. The local recurrence rate in patients with R1 or R2 margins was better in those irradiated (2 of 128 [2%]) compared to observed (13 of 64 [20%]) (hazard ratio [HR], 0.05; 95% CI, 0.01-0.24). Multivariable analysis for local recurrence found the following independent factors: age at diagnosis (HR for a 10-year increase in age, 1.33; 95% CI, 1.06-1.67), R1 vs R0 (HR, 5.21; 95% CI, 2.58-10.54), lymphovascular invasion (HR, 4.47; 95% CI, 1.43-13.99), and postoperative radiation therapy (HR, 0.10; 95% CI, 0.04-0.29). The 3-year local recurrence-free survivals for the study population were 96% vs 97% in the close margin group. Conclusions and Relevance: In this cohort study of patients with low- and intermediate-grade major salivary gland carcinoma, postoperative radiation therapy for positive margins was associated with decreased risk of local recurrence. In isolation from other risk factors for local recurrence, select patients with close surgical margins (≤1 mm) may safely be considered for observation.

Endovascular repair of radial artery non-anastomotic pseudoaneurysm in a radial forearm free flap.

The development of pseudoaneurysm is an uncommon, life-threatening complication of head and neck microvascular surgery. Only a handful of reports have been published describing microvascular pseudoaneurysms, which usually occur at the arterial anastomosis and present as a pulsatile neck mass or as haemorrhage in case of pseudoaneurysm rupture. Management is highly variable, especially in the acute setting. In patients with pseudoaneurysm where flap inosculation is inadequate, endovascular approaches may be appropriate. In this report, we describe a ruptured distal pedicle pseudoaneurysm of a radial forearm free flap salvaged with a flow-diverting stent with complete flap survival and pedicle preservation. We demonstrate further evidence and feasibility of endovascular treatment of a non-anastomotic pseudoaneurysm arising from small vessels when parent vascular integrity is critical to flap survival.

Radiologic-pathologic correlation of major versus minor extranodal extension in oral cavity cancer.

BACKGROUND: To evaluate the diagnostic performance of radiologic extranodal extension (rENE) in predicting major (>2 mm) and minor (≤2 mm) pathologic ENE (pENE). METHODS: All oral cavity squamous cell carcinoma patients who underwent neck dissection with pathological nodal disease (pN+) between 2010 and 2015 were reviewed. Preoperative computed tomography and/or magnetic resonance imaging were reviewed by two head and neck neuroradiologists. RESULTS: Three hundred and thirty-four patients were included. The sensitivity and specificity of rENE were 37% [95% CI 29-44] and 98% [95% CI 96-100], respectively. Sensitivity for pENE improved in the subset of patients with major ENE (48% [95% CI 38-57]). The presence of rENE was associated with inferior 3-year overall survival: 26% [95% CI 17-41] versus 60% [95% CI 54-67]. CONCLUSIONS: This large cohort study demonstrates high specificity, but low sensitivity for preoperative imaging in the detection of pENE in OCSCC. Patients with rENE demonstrated poor OS. pENE in the absence of rENE is still an adverse risk factor.

Optical imaging of bacterial infection in living mice using deep-red fluorescent squaraine rotaxane probes.

Two structurally related fluorescent imaging probes allow optical imaging of bacterial leg infection models in living athymic and immunocompetent mice. Structurally, the probes are comprised of a deep-red fluorescent squaraine rotaxane scaffold with two appended bis(zinc(II)-dicolylamine) (bis(Zn-DPA)) targeting ligands. The bis(Zn-DPA) ligands have high affinity for the anionic phospholipids and related biomolecules that reside within the bacterial envelope, and they are known to selectively target bacterial cells over the nearly uncharged membrane surfaces of healthy mammalian cells. Planar, whole-animal optical imaging studies showed that intravenous dosing of either probe (10 nmol) allowed imaging of localized infections of Gram-positive Staphylococcus aureus and Gram-negative Salmonella enterica serovar typhimurium. High selectivity for the infected target leg (T) over the contralateral nontarget leg (NT) was reflected by T/NT ratios up to six. The infection imaging signal was independent of mouse humoral immune status, and there was essentially no targeting at a site of sterile inflammation induced by injection of lambda-carrageenan. Furthermore, the fluorescent probe imaging signal colocalized with the bioluminescence signal from a genetically engineered strain of S. enterica serovar typhimurium. Although not highly sensitive (the localized infection must contain at least approximately 10(6) colony forming units for fluorescence visualization), the probes are remarkably selective for bacterial cells considering their low molecular weight (<1.5 kDa) and simple structural design. The more hydrophilic of the two probes produced a higher T/NT ratio in the early stages of the imaging experiment and washed out more rapidly from the blood clearance organs (liver, kidney). Therefore, it is best suited for longitudinal studies that require repeated dosing and imaging of the same animal. The results indicate that fluorescent probes based on squaraine rotaxanes should be broadly useful for in vivo animal imaging studies, and they further validate the ability of imaging probes with bis(Zn-DPA) ligands to selectively target bacterial infections in living animals.

Chronic Pain Management in Head and Neck Oncology.

Pain is epidemic in patients with head and neck cancer. Providers involved in the care of patients with head and neck cancer should be able to describe the common pain syndromes experienced by these patients, identify patients at risk of pain, and provide multimodal treatment of chronic pain. Treatment of chronic pain encompasses analgesic medications; adjuvant pharmacotherapy, including antidepressants and anticonvulsants; interventional techniques; as well as integrative medicine.

Systemic therapy for head and neck squamous cell carcinoma: Historical perspectives and recent breakthroughs.

OBJECTIVES: Despite dramatic developments in drugs established for other malignancies, historically there have been few novel systemic agents available for the management of head and neck squamous cell carcinoma (HNSCC). However, the last decade has observed increased interest in targeted therapies for HNSCC. In 2006, cetuximab became the first major drug for HNSCC to gain Food and Drug Administration (FDA) approval in 3 decades. Recently, both pembrolizumab and nivolumab gained FDA approval for treatment of recurrent or metastatic HNSCC, and trials for other indications in HNSCC are actively underway. As older agents including cisplatin and 5-fluorouracil continue to play a significant role in the management of advanced HNSCC, an understanding of their legacy is paramount. This historical review is not meant to exhaustively catalog every finding relating to HNSCC systemic therapy, but rather is meant to highlight important advances. DATA SOURCES: Case series and clinical trials available in the literature. REVIEW METHODS: Historically significant series and trials evaluating HNSCC systemic therapy were evaluated. RESULTS: Standard regimens employed today are largely comprised of drugs discovered over 4 decades ago, although a number of recent phase III clinical trials have shown great promise, leading to the adoption of several new chemotherapeutic agents and treatment strategies. CONCLUSIONS: These findings reinforce the importance of supporting further HNSCC drug discovery as modern treatment strategies using systemic therapy have resulted in measurable improvements in oncologic outcomes.

Head and Neck Cancer.

Despite a considerable expansion in our therapeutic repertoire for management of other malignancies, mortality from head and neck cancer (HNC) has not significantly improved in recent decades. Upon normalizing National Institutes of Health-awarded R01 and R01-equivalent grants by incidence, thyroid cancer ($214) and HNC ($1329) received the fewest funding dollars. Upon adjusting funding totals by mortality, HNC was 7th out of 9 cancers evaluated ($6138). These findings highlight HNC as an underfunded disease versus other cancers. As data detailing grant applications (including unsuccessful grants) are not publicly available, it is not clear if these disparities stem from fewer applications or fewer opportunities. Our hope is that this commentary will spur further investigation into strategies to increase HNC inquiry and funding for trainees as well as early-stage and established investigators.

Recent trends in oropharyngeal cancer funding and public interest.

OBJECTIVES/HYPOTHESIS: The incidence of oropharyngeal cancer (OPC) has increased in the United States. This has been driven by an increase in human papillomavirus (HPV)-positive OPC. Our objective is to determine trends in National Institutes (NIH)-supported research funding and public interest in OPC. METHODS: The NIH Research Portfolio Online Reporting Tools database was evaluated for projects related to OPC between 2004 and 2015. Projects were evaluated for total funding, relation to HPV, principal investigator departmental affiliation and degree, and NIH agency or center responsible for grant. The Google Trends database was evaluated for relative Internet search popularity of oropharyngeal cancer and related search terms between 2004 and 2015. RESULTS: In terms of NIH funding, 100 OPC-related projects representing 242 grant years and $108.5 million were funded between 2004 and 2015. Total NIH funding for OPC projects increased from $167,406 in 2004 to $16.2 million in 2015. Funding for HPV-related OPC increased from less than $2 million yearly between 2004 and 2010 up to $12.7 million in 2015. Principal investigators related to radiation oncology ($41.8 million) and with doctor of medicine degrees ($52.8 million) received the largest share of total funding. Relative Internet search popularity for oropharyngeal cancer has increased from 2004 to 2015 compared to control cancer search terms. CONCLUSION: Increased public interest and NIH funding has paralleled the rising incidence of OPC. NIH funding has been driven by projects related to the role of HPV in OPC. LEVEL OF EVIDENCE: 2c.

Cochlear implantation in unilateral sudden deafness improves tinnitus and speech comprehension: meta-analysis and systematic review.

OBJECTIVE: In recent years, otologists have begun to place cochlear implants into nonfunctioning ears after sudden unilateral hearing loss. Patients in these trials demonstrate differing degrees of hearing loss in the unimplanted ear. Few studies have examined the role of implantation in patients with normal hearing in the unimplanted ear. To understand if this practice benefits these patients in terms of tinnitus, sound localization, and speech understanding, the available world literature is reviewed. DATA SOURCES: MEDLINE, Embase, and Cochrane databases were searched for publications from database inception to June 1, 2013, without restriction of language. STUDY SELECTION: A search of multiple medical databases was performed to identify articles reporting cases series of cochlear implantation for unilateral hearing loss. Subjects were included for analysis only if the course of hearing loss was acute and rapidly progressive, if the loss was severe to profound, and if the contralateral ear had normal hearing. DATA EXTRACTION AND SYNTHESIS: Nine appropriate articles were identified, in which 36 patients met our inclusion criteria. Three meta-analyses were performed: of tinnitus (22 patients); of the lowest signal-to-noise ratio, which still allowed 50% sentence understanding (16 patients); and of sentence understanding at a fixed signal-to-noise ratio (12 patients). These found that measures of tinnitus reduction and decreased signal-to-noise ratios to still allow 50% speech discrimination were statistically significantly reduced. Systematic review of subjective changes of tinnitus in 27 patients, speech understanding in 16 patients, and sound localization in 16 patients found 96%, 100%, and 87% were improved, respectively. CONCLUSION: Cochlear implantation in unilateral sudden hearing loss with a normal functioning contralateral ear might prove to be an effective therapy. Tinnitus is reduced as is the signal-to-noise ratio, which still allows 50% speech discrimination. All patients felt that they localized sound better, and most felt that they understood speech better. Further studies should be conducted to compare the success of hearing rehabilitation of cochlear rehabilitation and traditional modalities such as contralateral routing of signal and bone-anchored hearing aids.
