The osteocutaneous radial forearm free flap: A multidisciplinary review of the evidence.

The osteocutaneous radial forearm (OCRFF) is a versatile free flap option for bony defects of the head and neck, given the thinness and pliability of the forearm cutaneous paddle, pedicle length, reliability, lack of atherosclerosis, and functional concerns common to other osseous donor sites. The OCRFF was once associated with a high risk of radial fracture, in addition to concerns about the quality and durability of bone stock for osseous reconstruction, particularly for the mandible. Following the introduction of prophylactic plating of the radius, the incidence of symptomatic radial fracture has drastically decreased. Furthermore, modifications of the bony osteotomies and other evolutions of this flap harvest have increased the use of the OCRFF throughout the head and neck. Despite these advantages, the OCRFF is not widely utilized by microvascular reconstructive surgeons due to perceived limitations and risks. Herein, we present a multidisciplinary, contemporary review of the harvest technique, outcomes, and perioperative management for the OCRFF.

Evaluating the Accuracy of ChatGPT in Common Patient Questions Regarding HPV+ Oropharyngeal Carcinoma.

OBJECTIVES: Large language model (LLM)-based chatbots such as ChatGPT have been publicly available and increasingly utilized by the general public since late 2022. This study sought to investigate ChatGPT responses to common patient questions regarding Human Papilloma Virus (HPV) positive oropharyngeal cancer (OPC). METHODS: This was a prospective, multi-institutional study, with data collected from high volume institutions that perform >50 transoral robotic surgery cases per year. The 100 most recent discussion threads including the term "HPV" on the American Cancer Society's Cancer Survivors Network's Head and Neck Cancer public discussion board were reviewed. The 11 most common questions were serially queried to ChatGPT 3.5; answers were recorded. A survey was distributed to fellowship trained head and neck oncologic surgeons at 3 institutions to evaluate the responses. RESULTS: A total of 8 surgeons participated in the study. For questions regarding HPV contraction and transmission, ChatGPT answers were scored as clinically accurate and aligned with consensus in the head and neck surgical oncology community 84.4% and 90.6% of the time, respectively. For questions involving treatment of HPV+ OPC, ChatGPT was clinically accurate and aligned with consensus 87.5% and 91.7% of the time, respectively. For questions regarding the HPV vaccine, ChatGPT was clinically accurate and aligned with consensus 62.5% and 75% of the time, respectively. When asked about circulating tumor DNA testing, only 12.5% of surgeons thought responses were accurate or consistent with consensus. CONCLUSION: ChatGPT 3.5 performed poorly with questions involving evolving therapies and diagnostics-thus, caution should be used when using a platform like ChatGPT 3.5 to assess use of advanced technology. Patients should be counseled on the importance of consulting their surgeons to receive accurate and up to date recommendations, and use LLM's to augment their understanding of these important health-related topics.

Local intralesional talimogene laherparepvec therapy with complete local response in oral palatine mucosal melanoma: a case report.

BACKGROUND: Mucosal melanoma, an aggressive type of malignancy different from the cutaneous melanomas commonly seen in the head and neck region, represents < 1% of all malignant melanomas. The pathogenesis of mucosal melanoma is unknown. Targetable mutations commonly seen in cutaneous melanoma, such as in the BRAF and NRAS genes, have a lower incidence in mucosal melanoma. Mucosal melanoma carries a distinct mutational pattern from cutaneous melanoma. Surgery with negative margins is the first-line treatment for mucosal melanoma, and systemic therapy is not well defined. Talimogene laherparepvec, an oncolytic viral immunotherapy, is United States Food and Drug Administration approved for the treatment of advanced malignant cutaneous melanoma, with local therapeutic benefits. Mucosal melanoma was initially excluded from talimogene laherparepvec's initial phase III clinical trial. CASE PRESENTATION: We present the case of a white female patient in her 40s with past medical history of systemic lupus erythematous, scleroderma, and estrogen-receptor-positive invasive ductal breast carcinoma. Following a bilateral mastectomy, the patient was found to have BRAF-negative mucosal melanoma of her hard palate with a soft palate skip lesion. Owing to the presence of a skip mucosal lesion as well as the anticipated defect and need for free-flap reconstructive surgery, nonsurgical management was considered. The patient was referred to medical oncology, where-based on the patient's complicated medical history and the risk of immunotherapy possibly worsening her prior autoimmune diseases-local talimogene laherparepvec injections were chosen as the primary therapy for her mucosal lesions. Though talimogene laherparepvec is approved for the treatment of cutaneous melanoma, there are limited data available on the use of talimogene laherparepvec in mucosal melanomas. CONCLUSION: The patient had a complete local tumor response at both the primary lesion as well as the skip lesion with the local injections. She had no side effects and maintained a high quality of life during treatment.

Implementation considerations for the adoption of artificial intelligence in the emergency department.

OBJECTIVE: Artificial intelligence (AI) has emerged as a potentially transformative force, particularly in the realm of emergency medicine (EM). The implementation of AI in emergency departments (ED) has the potential to improve patient care through various modalities. However, the implementation of AI in the ED presents unique challenges that influence its clinical adoption. This scoping review summarizes the current literature exploring the barriers and facilitators of the clinical implementation of AI in the ED. METHODS: We systematically searched Embase (Ovid), MEDLINE (Ovid), Web of Science, and Engineering Village. All articles were published in English through November 20th, 2023. Two reviewers screened the search results, with disagreements resolved through third-party adjudication. RESULTS: A total of 8172 studies were included in the preliminary search, with 22 selected for the final data extraction. 10 studies were reviews and the remaining 12 were primary quantitative, qualitative, and mixed-methods studies. Out of the 22, 13 studies investigated a specific AI tool or application. Common barriers to implementation included a lack of model interpretability and explainability, encroachment on physician autonomy, and medicolegal considerations. Common facilitators to implementation included educating staff on the model, efficient integration into existing workflows, and sound external validation. CONCLUSION: There is increasing literature on AI implementation in the ED. Our research suggests that the most common barrier facing AI implementation in the ED is model interpretability and explainability. More primary research investigating the implementation of specific AI tools should be undertaken to help facilitate their successful clinical adoption in the ED.

Effectiveness of Nasolacrimal SCC Treatments and Promising Role of Chemo-Induction: A Case Report and Systematic Review.

OBJECTIVE: To comprehensively analyze reported cases of nasolacrimal squamous cell carcinoma (NLSCC), focusing on risk factors, treatment modalities, and outcomes. Additionally, investigate the impact of human Papillomavirus (HPV) status and histopathological subtypes' impact on prognosis. DATA SOURCES: Pubmed, Embase. REVIEW METHODS: We conducted a systematic literature review to identify relevant studies reporting cases of NLSCC. The review methods adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The final update was performed on May 31, 2023. RESULTS: The 72 studies included a total of 313 participants (mean age: 55; 60% male). Longer symptom duration (44.1 ± 59.2 months) correlated with recurrence (p = 0.004), and males exhibited higher mortality rates (19.6% vs. 2.4% in females, p = 0.01). The overall survival (OS) rate among all patients was 87.1%. Basaloid NLSCC had a worse death outcome (p ≤ 0.001). HPV-positive cases showed comparable OS, recurrence, and metastasis rates to the general population (p = 0.917, 0.851, 0.07, respectively). Comparing treatment approaches (surgery, surgery with adjuvant radiation, chemoradiotherapy [CRT] followed by surgery), no significant differences in 5 and 10-year OS rates or recurrence were observed (p = 0.4, 0.24, respectively), but 5-year metastasis events were significant (p = 0.024). Eye exenteration rates were 31.1%, 20%, and 0% for the respective treatments (p = 0.089). Induction chemotherapy saved four cases from potential exenteration with favorable prognosis. CONCLUSION: Early detection and diagnosis are of utmost importance in the management of NLSCC. Regardless of the treatment approach, HPV-related NLSCC demonstrated similar outcomes to the general population. Basaloid histology represents the worst subtype in terms of prognosis. Limited adjuvant CRT cases showed improved outcomes and induction chemotherapy's importance was emphasized in recent literature and our shared experience. Laryngoscope, 134:3892-3902, 2024.

The osteocutaneous radial forearm free flap: A pictorial essay.

The osteocutaneous radial forearm free flap (OCRFFF) is a versatile flap with the ability to reconstruct complex defects. We detail the techniques necessary to harvest an OCRFFF, including an outline on making 90-degree osteotomies to maximize bone harvest. In this pictorial essay, we provide illustrations of the anatomy and surgical techniques necessary for OCRFFF harvest. Detailed discussion is provided on how to protect the perforators to the bone and the approach to making osteotomies in a 90-degree fashion. The approach for prophylactic plating of the radius to prevent radius fractures is outlined. A case presentation on the real-life utilization of this flap is included. The OCRFFF is an excellent head and neck reconstructive option. While there are limitations to its use for patients requiring dental rehabilitation or long/anterior mandibular defects, for the right patient and indication it has shown great success in reconstructive efforts.

A Longitudinal Investigation of Lower-Risk Gambling Limits in the Canadian National Study.

Recent years have seen increased attention given to identifying and describing the levels of gambling participation that confer a risk of harm in order to generate public health advice regarding lower-risk gambling. However, most of the existing literature has failed to explicitly assess these limits in a prospective manner. The purpose of this study is to employ a methodology consistent with prior investigations to evaluate the level of gambling participation associated with an increased risk of future gambling-related harm. Using data from the Alberta Gambling Research Institute's National Project Online Panel Survey, risk ratios and Receiver Operating Characteristic (ROC) analyses were used to determine the relative risk of gambling-related harm associated with participating in a greater number of gambling formats, gambling more days per month, and spending a greater proportion of income gambling. Prospective lower-risk limits were largely consistent with those identified in previous cross-sectional analyses (e.g., no more than two gambling formats, no more than once a week), with the exception that higher limits were found for the percent of household income spent gambling (3.4-6.4% vs. 1%). We advise that future research on lower-risk gambling limits consider the use of more granular assessment instruments and prospective methods to more closely evaluate the association between gambling participation and gambling harm.

Immunoprofiles and Oncologic Outcomes of 15 Patients with Androgen Receptor-Positive Salivary Duct Carcinoma.

BACKGROUND: Salivary duct carcinomas (SDC) are a rare and aggressive subtype of salivary gland neoplasm. They can present with distinct immunoprofiles, such as androgen receptor (AR) and HER-2/Neu-positivity. To date, no consensus exists on how to best manage this entity. METHODS: All patients diagnosed with nonmetastatic AR+ SDC of the parotid from 2013 to 2019 treated with curative intent were included. Immunologic tumor profiling was conducted using 24 distinct markers. Kaplan-Meier analyses were used to estimate locoregional recurrence (LRR), distant control, and overall survival (OS). RESULTS: Fifteen patients were included. Nine (60%) patients presented with T4 disease and eight (53%) had positive ipsilateral cervical lymphadenopathy. Ten (67%) patients underwent trimodality therapy, including surgery followed by adjuvant radiation and concurrent systemic therapy. The median follow-up was 5.5 years (interquartile range, 4.8-6.1). The estimated 5-year rates of LRR, distant progression, and OS were 6%, 13%, and 87%, respectively. CONCLUSION: Despite only including AR+ SDC of the parotid, immunoprofiles, such as expression of HER-2, were highly variable, highlighting the potential to tailor systemic regimens based on individual histologic profiles in the future. Studies with larger patient numbers using tumor-specific molecular profiling and tumor heterogeneity analyses are justified to better understand the biology of these tumors. Molecularly informed treatment approaches, including the potential use of AR- and HER-2/Neu-directed therapies upfront in the definitive setting, may hold future promise to further improve outcomes for these patients.

A Pilot Study: Free Flap Atrophy in Tongue Reconstruction Using 3D Volumetric Analysis.

OBJECTIVE: To identify factors influencing volume change in non-osseous oral free flap reconstruction using postoperative cross-sectional imaging and 3-dimensional segmentation of the free flap's muscular and adipose tissue content. METHODS: Oral tongue free flap reconstruction cases (2014-2019) were reviewed with inclusion of patients with 3 postoperative, cross-sectional imaging studies with 1 within 6 months, 1 within 1 year, and 1 that spanned 2 years post-reconstruction. Exclusion criteria included recurrence, significant dental artifact, bony reconstruction, and flap failure. Demographics, risk factors, and surgical/clinical treatments were identified. Flap volumes were measured using Materialise MIMICS. RESULTS: Twenty-two patients met strict inclusion criteria. Four flaps were anterolateral thighs and 18 radial forearms. Median percent volume loss greater than 2 years post-reconstruction was 53.2% overall, 58.1% for radial forearms, and 45.4% for ALTs (21.4% for adipose tissue and 57.4% for muscular tissue). Univariate analysis revealed glossectomy amount was associated with percent volume loss (P = .0417). Each successive postoperative month, the flap decreased by 1.54% (P < .0001). Checking for the interaction effect, the percent of flap loss across time was different for glossectomy amount (P = .0093), obesity status (P = .0431), and base of tongue involvement (P = .0472). CONCLUSION: Glossectomy type, and thus flap size, is a positive predictor for flap atrophy. Obesity and base of tongue involvement are negative predictors for flap atrophy. The amount of tissue loss may differ from classical teachings with median atrophy 53.2% greater than 2 years post-reconstruction.

National Trends in 30-Day Readmission Following Transoral Robotic Surgery for Oropharyngeal Squamous Cell Carcinoma.

Importance: As the incidence of oropharyngeal squamous cell carcinoma (OPSCC) continues to rise in the US, an increasing number of patients are being treated with transoral robotic surgery (TORS). Readmission following surgery can potentially delay initiation of adjuvant treatment and affect survival outcomes. Objective: To identify risk factors for 30-day postoperative readmission in patients undergoing TORS for OPSCC. Design, Setting, and Participants: This retrospective, population-based cohort study used data from the Nationwide Readmissions Database from 2010 to 2017. All patients undergoing TORS for OPSCC were identified using International Classification of Diseases codes and included. Exclusion criteria were age younger than 18 years or incomplete information regarding index admission or readmission. The analysis was performed from April to October 2023. Exposure: TORS for OPSCC. Main Outcomes and Measures: Univariate and multivariate analyses were performed to determine factors associated with 30-day readmission. Covariates included demographics and medical comorbidities, socioeconomic factors, hospital characteristics, and surgical details. Trends in readmission over time, reasons for readmission, and characteristics of the readmission were also examined. Results: A weighted total of 5544 patients (mean [SD] age, 60.7 [0.25] years; 4475 [80.7%] male) underwent TORS for OPSCC. The overall readmission rate was 17.5% (n = 971), and these rates decreased over the study period (50 of 211 patients [23.7%] in 2010 vs 58 of 633 patients [9.1%] in 2017). Risk factors associated with readmission included male sex (adjusted odds ratio [AOR], 1.54; 95% CI, 1.07-2.20) and a diagnosis of congestive heart failure (AOR, 2.42; 95% CI, 1.28-4.58). Factors associated with decreased rate of readmission included undergoing concurrent selective neck dissection (AOR, 0.30; 95% CI, 0.22-0.41). Among the 971 readmissions, the most common readmission diagnoses were bleeding (151 [15.6%]), electrolyte and digestive problems (44 [4.5%]), pneumonia (44 [4.5%]), and sepsis (26 [2.7%]). Conclusions and Relevance: In this cohort study, readmission rates following TORS for oropharynx cancer decreased over time; however, a subset of patients required readmission most commonly related to bleeding, infection, and electrolyte imbalance. Concurrent neck dissection may be protective against readmission. Elucidation of risk factors for readmission after TORS for OPSCC offers opportunities for evidence-based shared decision-making, quality improvement initiatives, and improved patient counseling.

Demographic and Academic Productivity Trends Among American Head & Neck Society Fellows Over a 20-Year Period.

Importance: Historical data reveal that, compared with women, men are more likely to pursue a head and neck surgical oncology fellowship, but little is known about possible gender differences in academic productivity. Objective: To assess demographic trends and academic productivity among American Head & Neck Society (AHNS) fellowship graduates. Design, Setting, and Participants: This cross-sectional study used electronically published data from the AHNS on fellowship graduates in the US and Canada from July 1, 1997, to June 30, 2022. Scopus was used to extract h-indices for each graduate. Exposure: Scholarly activity. Main Outcomes and Measures: Main outcomes were changes in demographic characteristics and academic productivity among AHNS graduates over time. Data analysis included effect size, η2, and 95% CIs. Results: A total of 691 AHNS fellowship graduates (525 men [76%] and 166 women [24%]) were included. Over the study period, there was an increase in the number of programs offering a fellowship (η2, 0.84; 95% CI, 0.68-0.89) and an increase in the absolute number of women who completed training (η2, 0.66; 95% CI, 0.38-0.78). Among early-career graduates pursuing an academic career, there was a small difference in the median h-index scores between men and women (median difference, 1.0; 95% CI, -1.1 to 3.1); however, among midcareer and late-career graduates, there was a large difference in the median h-index scores (midcareer graduates: median difference, 4.0; 95% CI, 1.2-6.8; late-career graduates: median difference, 6.0; 95% CI, 1.0-10.9). A higher percentage of women pursued academic positions compared with men (106 of 162 [65.4%] vs 293 of 525 [55.8%]; difference, 9.6%; 95% CI, -5.3% to 12.3%). Conclusions and Relevance: This cross-sectional study suggests that women in head and neck surgery begin their careers with high levels of academic productivity. However, over time, a divergence in academic productivity between men and women begins to develop. These data argue for research to identify possible reasons for this observed divergence in academic productivity and, where possible, develop enhanced early faculty development opportunities for women to promote their academic productivity, promotion, and advancement into leadership positions.

Body Mass Index (BMI) Related Morbidity with Thyroid Surgery.

OBJECTIVES: The increase in incidence of thyroid cancer correlates with strict increases in body mass index (BMI) and obesity in the United States. Thyroid hormone dysregulation has been shown to precipitate circulatory volume, peripheral resistance, cardiac rhythm, and even cardiac muscle health. Theoretically, thyroid surgery could precipitate injury to the cardiopulmonary system. METHODS: The American College of Surgery National Quality Improvement Program database was queried for thyroidectomy cases in the 2007-2020 Participant User files. Continuous and categorical associations between BMI and cardiopulmonary complications were investigated as reported in the database. RESULTS: The query resulted 186,095 cases of thyroidectomy procedures in which the mean age was 51.3 years and sample was 79.3% female. No correlation was evident in univariate and multivariate analyses between BMI and the incidence of postoperative stroke or myocardial infarction. The incidence of complications was extremely low. However, risk of deep venous thrombosis correlated with BMI in the categorical, univariate, and multivariate (OR 1.036, CI 1.014-1.057, p < 0.01) regression analysis. Additionally, increased BMI was associated with increased risk of pulmonary embolism (PE) (OR 1.050 (1.030, 1.069), p < 0.01), re-intubation (OR 1.012 (1.002, 1.023), p = 0.02), and prolonged intubation (OR 1.031 (1.017, 1.045), p < 0.01). CONCLUSION: Despite the rarity of cardiopulmonary complications during thyroid surgery, patients with very high BMI carry a significant risk of deep venous thrombosis, PE, and prolonged intubation. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:2823-2830, 2023.

Are There Riskier Types of Gambling?

Gambling-related harm is a public health issue requiring market regulation and efforts aimed at prevention and treatment. An important consideration for the regulation of gambling is whether certain types of gambling are intrinsically more harmful than others. The present study was a comprehensive investigation of this issue in a nationwide sample of 10,199 Canadian adult gamblers that included 1346 individuals with problem gambling. We investigated (a) the univariate cross-sectional association between individual types of gambling and problem gambling; (b) the cross-sectional association between individual gambling types and problem gambling when controlling for breadth of gambling involvement; (c) the prospective/lagged relationship between participation in different gambling types and future problem gambling; and (d) the self-reports of people with gambling problems concerning the types and modalities they consider to be most problematic. Our collective results indicate that breadth of gambling involvement is a stronger predictor of gambling problems than involvement in any particular type, but that involvement in certain types (electronic gambling machines in particular, and casino table games and online gambling to a lesser extent) does confer additional risk.

History, Innovation, Pearls, and Pitfalls in Complex Midface Reconstruction.

Midface reconstruction in head and neck cancer or individuals with extensive trauma to the face has evolved significantly over the past few decades with the introduction of free flap reconstruction and virtual surgical planning enabling surgeons to obtain optimal cosmetic and functional outcomes. Traditional methods such as the use of obturators or local flaps still have a role in select situations, but complex defects have been replaced by the advent of microvascular free tissue transfer and virtual planning, which can commonly provide a single-stage reconstruction of the midface with excellent aesthetic and functional results. This article provides an overview of the history and evolution of midface reconstruction, a discussion of how to integrate virtual surgical planning into a surgical practice, an example of a complex midface reconstruction case, and pearls and pitfalls that have been experienced by an experienced reconstructive team.

Long-term outcomes after osteochondral allograft transplantation to the humeral head.

BACKGROUND: Long-term outcomes of osteochondral allograft (OCA) transplantation to the humeral head have been sparsely reported in the literature. PURPOSE: To evaluate outcomes and survivorship of OCA transplantation to the humeral head in patients with osteochondral defects at a minimum of 10 years of follow-up. METHODS: A registry of patients who underwent humeral head OCA transplantation between 2004 and 2012 was reviewed. Patients completed pre and postoperative surveys including the American Shoulder and Elbow Surgeons score, Simple Shoulder Test, Short Form 12 (SF-12), and the visual analog scale. Failure was defined by conversion to shoulder arthroplasty. RESULTS: Fifteen of 21 (71%) patients with a minimum of ten year of follow-up (mean: 14.2 ± 2.40) were identified. Mean patient age was 26.1 ± 8.8 years at the time of transplantation and eight (53%) patients were male. Surgery was performed on the dominant shoulder in 11 of the 15 (73%) cases. The use of local anesthetic delivered via an intra-articular pain pump was the most often reported underlying etiology of chondral injury (n = 9; 60%). Eight (53%) patients were treated with an allograft plug, while seven (47%) patients were treated with a mushroom cap allograft. At final follow-up, mean American Shoulder and Elbow Surgeons (49.9 to 81.1; P = .048) and Simple Shoulder Test (43.1 to 83.3; P = .010) significantly improved compared to baseline. Changes in mean SF-12 physical (41.4 to 48.1; P = .354), SF-12 mental (57.5 to 51.8; P = .354), and visual analog scale (4.0 to 2.8; P = .618) did not reach statistical significance. Eight (53%) patients required conversion to shoulder arthroplasty at an average of 4.8 ± 4.7 years (range: 0.6-13.2). Kaplan-Meier graft survival probabilities were 60% at 10 years and 41% at 15 years. CONCLUSION: OCA transplantation to the humeral head can result in acceptable long-term function for patients with osteochondral defects. While patient-reported outcomes metrics were generally improved compared to baseline, OCA graft survival probabilities diminished with time. The findings from this study can be used to counsel future patients with significant glenohumeral cartilage injuries and set expectations about the potential for further surgery.

Patient-Specific Variables Associated with Failure to Achieve Clinically Significant Outcomes After Meniscal Allograft Transplantation at Minimum 5 Year Follow-Up.

PURPOSE: To determine the improvements in patient-reported outcome measures (PROMs) necessary to achieve minimal clinically important difference (MCID), patient-acceptable symptomatic state (PASS), and substantial clinical benefit (SCB) after primary meniscal allograft transplantation (MAT) at a minimum of 5-year follow-up, while identifying variables predictive of achieving clinically significant outcomes (CSOs). METHODS: A retrospective review was performed to identify patients undergoing primary MAT at a single institution from 1999 to 2016. Lysholm, International Knee Documentation Committee (IKDC), and Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales were collected before surgery and at a minimum of 5-year follow-up. A distribution-based approach was used to calculate MCID, whereas an anchor-based approach was used to calculate SCB and PASS. Multivariate logistic regression was performed to determine factors associated with CSO achievement. RESULTS: A total of 202 patients undergoing MAT (56% medial, 44% lateral) were included with a mean follow-up of 9.8 ± 4.1 years, age of 29.7 ± 8.5 years, and body mass index (BMI) of 26.5 ± 4.7. Thresholds for achieving MCID, PASS, and SCB, respectively, at a minimum 5-year follow-up for Lysholm (10.3, 74.5, 32.5), IKDC (12.1, 55.6, 29.1), and KOOS subscales questionnaires (Pain [11.0, 70.7, 25.1], Symptoms [11.0, 60.8, 19.6], Activities of Daily Living [10.5, 90.3, 17.9], Sport [16.2, 47.4, 37.5], and Quality of Life [13.6, 40.5, 37.3]) were calculated. Reduced odds of achieving MCID were associated with higher preoperative PROM scores, BMI, patient age, concomitant osteotomy, male sex, and worker's compensation (WC) status. Reduced odds of achieving PASS were associated with lower preoperative PROM scores, higher BMI (particularly ≥30), patient age, and WC status. Reduced odds of achieving SCB were associated with higher preoperative PROM scores and WC status. CONCLUSIONS: This study established the MCID, PASS, and SCB at 5-year minimum follow-up for the Lysholm score, IKDC, and KOOS subscales in patients who underwent MAT. Increased BMI and patient age, male sex, performance of concomitant osteotomy, WC status, and preoperative PROM scores were associated with failure to achieve CSOs after primary MAT at a minimum of 5-year follow-up. LEVEL OF EVIDENCE: Level IV, therapeutic study, retrospective case series.

Immediate resection of positive margins improves local control in oral tongue cancer.

OBJECTIVES: This study investigates the impact of immediate resection of positive margins on local control of oral tongue cancer. MATERIALS AND METHODS: We analyzed 273 consecutive oral tongue cancers resected from 2013 to 2018. Additional resection was performed in cases during the initial operation based on surgeon inspection of the specimen and/or frozen margins. Positive margins were defined as invasive carcinoma/high-grade dysplasia < 1 mm from the inked edge. Patients were grouped as follows: negative margin (Group 1); positive margin with immediate additional tissue resection (Group 2); and positive margin without additional tissue resection (Group 3). RESULTS: Overall, the rate of local recurrence was 7.7 % (21/273), and the rate of positive main specimen margin was 17.9 %. Of these patients, 38.8 % (19/49) underwent immediate additional resection of the presumed positive margin. Group 3 had higher local recurrence rates than Group 1 after adjustment for T-stage (aHR 2.8 [95 % CI 1.0-7.7], p = 0.04). Group 2 had similar rates of local recurrence (aHR 0.45 [95 % CI 0.06-3.6], p = 0.45). Three year local recurrence free survival for Groups 1, 2, and 3 were 91 %, 92 % and 73 %, respectively. Compared to the main specimen margin, sensitivity of intraoperative frozen tumor bed margins was 17.4 %, and specificity was 95 %. CONCLUSION: In patients with positive main specimen margins, anticipation and detection in real-time with immediate additional tissue resection reduced local recurrence to rates similar to those with negative main specimen margins. These findings support the use of technology to provide real-time intraoperative margin data and guide additional resection for improved local control.

Transgender health and the impact of aging and menopause.

Gender affirming hormone therapy (GAHT) is used by many transgender people to reduce gender incongruence and improve psychological functioning. As GAHT shares many similarities with menopausal hormone therapy, clinicians supporting people through menopause are ideally placed to manage GAHT. This narrative review provides an overview of transgender health and discusses long-term effects of GAHT to consider when managing transgender individuals across the lifespan. Menopause is less relevant for transgender individuals who take GAHT (often given lifelong) to achieve sex steroid concentrations generally in the range of the affirmed gender. For people using feminizing hormone therapy, there is an elevated risk of venous thromboembolism, myocardial infarction, stroke and osteoporosis relative to cisgender individuals. For trans people using masculinizing hormone therapy, there is an increased risk of polycythemia, probable higher risk of myocardial infarction and pelvic pain which is poorly understood. Proactive mitigation of cardiovascular risk factors is important for all transgender people and optimization of bone health is important for those using feminizing hormones. With a lack of research to guide GAHT in older age, a shared decision-making approach is recommended for the provision of GAHT to achieve individual goals whilst minimizing potential adverse effects.

Hypothyroidism as an Independent Predictor of 30-day Readmission in Head and Neck Cancer Patients.

OBJECTIVES: To define the role of hypothyroidism and other risk factors for unplanned readmissions after surgery for head and neck cancer. STUDY DESIGN: Retrospective cohort study. METHODS: The Nationwide Readmission Database (NRD) was used to identify patients who underwent surgery for mucosal head and neck cancer (oral cavity, oropharynx, larynx, and hypopharynx) between 2010 and 2017. Univariate and multivariate logistic regression were performed to determine patient, tumor, and hospital related risk factors for 30-day readmission. Readmitted patients were stratified by preoperative diagnosis of hypothyroidism to compare readmission characteristics. RESULTS: For the 131,013 patients who met inclusion criteria, the readmission rate was 15.9%. Overall, 11.91% of patients had a preoperative diagnosis of hypothyroidism. After controlling for other variables, patients with a preoperative diagnosis of hypothyroidism had 12.2% higher odds of readmission compared to those without hypothyroidism (OR: 1.12, 1.03-1.22, p = 0.008). Patients with hypothyroidism had different reasons for readmission, including higher rates of wound dehiscence, fistula, infection, and electrolyte imbalance. Among readmitted patients, the length of stay for index admission (mean 10.5 days vs. 9.2 days, p < 0.001), readmission (mean 7.0 vs. 6.6 days, p = 0.05), and total hospital charge were higher for hypothyroid patients ($137,742 vs. $119,831, p < 0.001). CONCLUSION: Hypothyroidism is an independent risk factor for 30-day readmission following head and neck cancer resection. Furthermore, hypothyroid patients are more likely to be readmitted for wound complications, infection, and electrolyte imbalance. Targeted interventions should be considered for hypothyroid patients to decrease readmission rates and associated patient morbidity, potentially leading to earlier initiation of adjuvant treatment.

Use of 3-dimensional printing at the point-of-care to manage a complex wound in hemifacial necrotizing fasciitis: a case report.

BACKGROUND: Complex facial wounds can be difficult to stabilize due to proximity of vital structures. We present a case in which a patient-specific wound splint was manufactured using computer assisted design and three-dimensional printing at the point-of-care to allow for wound stabilization in the setting of hemifacial necrotizing fasciitis. We also describe the process and implementation of the United States Food and Drug Administration Expanded Access for Medical Devices Emergency Use mechanism. CASE PRESENTATION: A 58-year-old female presented with necrotizing fasciitis of the neck and hemiface. After multiple debridements, she remained critically ill with poor vascularity of tissue in the wound bed and no evidence of healthy granulation tissue and concern for additional breakdown towards the right orbit, mediastinum, and pretracheal soft tissues, precluding tracheostomy placement despite prolonged intubation. A negative pressure wound vacuum was considered for improved healing, but proximity to the eye raised concern for vision loss due to traction injury. As a solution, under the Food and Drug Administration's Expanded Access for Medical Devices Emergency Use mechanism, we designed a three-dimensional printed, patient-specific silicone wound splint from a CT scan, allowing the wound vacuum to be secured to the splint rather than the eyelid. After 5 days of splint-assisted vacuum therapy, the wound bed stabilized with no residual purulence and developed healthy granulation tissue, without injury to the eye or lower lid. With continued vacuum therapy, the wound contracted to allow for safe tracheostomy placement, ventilator liberation, oral intake, and hemifacial reconstruction with a myofascial pectoralis muscle flap and a paramedian forehead flap 1 month later. She was eventually decannulated and at six-month follow-up has excellent wound healing and periorbital function. CONCLUSIONS: Patient-specific, three-dimensional printing is an innovative solution that can facilitate safe placement of negative pressure wound therapy adjacent to delicate structures. This report also demonstrates feasibility of point-of-care manufacturing of customized devices for optimizing complex wound management in the head and neck, and describes successful use of the United States Food and Drug Administration's Expanded Access for Medical Devices Emergency Use mechanism.
