Extranodal marginal zone lymphoma of the larynx: A case report and scoping review.

BACKGROUND: This scoping review aims to review cases of extranodal marginal zone lymphoma (MZL) of the larynx to establish best management practices for this rare clinical entity. METHODS: In this paper, we report a case of laryngeal MZL, in accordance with CARE guidelines. We then performed a scoping review according to PRISMA-ScR criteria of published cases of MZL involving the larynx. The following data were collected for each case: age, sex, size, location(s) involved, stage, treatment, follow-up, and recurrence duration. RESULTS: Sixty-six patients with laryngeal MZL, first reported in 1990, were identified. Characterized by its low-grade histological appearance and indolent course, laryngeal MZL is generally confined to the larynx and has an excellent prognosis with radiation used as first-line therapy. CONCLUSIONS: It is imperative for clinicians to consider lymphoma in the differential diagnosis of a laryngeal tumor from any subsite, as certain pathologies may carry high risks of metastasis.

Development and clinical implementation of a digital workflow utilizing 3D-printed oral stents for patients with head and neck cancer receiving radiotherapy.

OBJECTIVES: We describe the development of 3D-printed stents using our digital workflow and their effects on patients enrolled in the lead-in phase of a multi-center, randomized Phase-II trial. MATERIALS AND METHODS: Digital dental models were created for patients using intraoral scanning. Digital processes were implemented to develop the mouth-opening, tongue-depressing, and tongue-lateralizing stents using stereolithography. Time spent and material 3D-printing costs were measured. Physicians assessed mucositis using the Oral Mucositis Assessment Scale (OMAS) and collected MD Anderson Symptom Inventory (MDASI) reports and adverse events (AEs) from patients at various time points (TPs). OMAS and MDASI results were evaluated using paired t-test analysis. RESULTS: 18 patients enrolled into the lead-in phase across 6 independent clinical sites in the USA. 15 patients received stents (average design and fabrication time, 8 h; average material 3D-printing cost, 11 USD). 10 eligible patients with complete OMAS and MDASI reports across all TPs were assessed. OMAS increased significantly from baseline to week 3 of treatment (mean difference = 0.34; 95 % CI, 0.09-0.60; p = 0.01). MDASI increased significantly from baseline to week 3 of treatment (mean difference = 1.02; 95 % CI, 0.40-1.70; p = 0.005), and week 3 of treatment to end of treatment (mean difference = 1.90; 95 % CI, 0.90-2.92; p = 0.002). AEs (grades 1-3) were reported by patients across TPs. Mucositis and radiation dermatitis were primarily attributed to chemoradiation. CONCLUSIONS: 3D-printed stents were successfully fabricated and well tolerated by patients. As patients enroll in the randomized phase of this trial, data herein will establish a baseline for comparative analysis.

Trait Mindfulness and Social Support Predict Lower Perceived Stress Burden in Patients Undergoing Radiation Therapy.

Purpose: Cancer diagnosis and treatment, including radiation therapy (RT), cause significant patient stress. Mindfulness and social support have been shown to help manage the psychological effects of cancer treatment. The objective of our study was to determine the sociodemographic and clinical factors associated with stress burden in patients receiving RT. Methods and Materials: Patients receiving RT for cancer at a single institution were given a 3-section survey to complete during the first on-treatment visit. The survey included the Perceived Stress Scale, Medical Outcomes Study Social Support Survey, and Mindfulness Attention Awareness Scale, which were used to measure stress, social support, and trait mindfulness, respectively. Linear regression analysis was performed to determine associations between perceived stress and age, patient sex, race and ethnicity, treatment intent, disease site, trait mindfulness, and social support. Factors significant in univariable analysis were analyzed with a multivariable analysis. Results: A total of 93 patients undergoing RT at a tertiary care academic institution were recruited from July to September 2019. Median scores for Perceived Stress Scale, Medical Outcomes Study Social Support Survey, and Mindfulness Attention Awareness Scale were 14.6 (range, 0-31; SD, 6.9), 4.2 (range, 1-5; SD, 1.0), and 5.1 (range, 3.1-6.0; SD, 0.8), respectively. On univariable analysis, mindfulness and social support were associated with decreased stress burden, and female sex and palliative intent were associated with increased stress burden. These factors all maintained significance in multivariable analysis. Conclusions: These results suggest measures to improve mindfulness and perceived social support, such as mindfulness meditation and psychoeducational approaches, may lessen the stress burden and improve quality of life for patients undergoing RT. Future studies should analyze the longitudinal impact of individual patient characteristics, including patient sex and treatment intent, to better understand their effects on psychological maladjustment during cancer care.

Children and adolescents rectify unequal allocations of leadership duties in the classroom.

Little is known about how children and adolescents evaluate unequal teacher allocations of leadership duties based on ethnicity-race and gender in the classroom. U.S. boys and girls, White (40.7%), Multiracial (18.5%), Black/African American (16.0%), Latine (14.2%), Asian (5.5%), Pacific Islander (0.4%), and other (4.7%) ethnic-racial backgrounds, 8-14 years, N = 275, evaluated teacher allocations of high-status leadership positions favoring specific ethnic-racial or gender groups during 2018-2021. Adolescents, more than children, negatively evaluated unequal teacher allocations of leadership duties that resulted in group-based inequalities, expected peers who shared the identity of a group disadvantaged by the teacher's allocation to view it more negatively than others, and rectified inequalities. Understanding perceptions of teacher-based bias provides an opportunity for interventions designed to create fair and just classrooms that motivate all students to achieve.

Vallecular cyst causing sleep-disordered breathing in an older child.

Consensus-based recommendations are needed to better guide paediatric otolaryngologists in providing standardised care to children with sleep-disordered breathing (SDB). Here we present a unique case of vallecular cyst found during SDB workup in a patient in their middle childhood (6-12 years old). While the patient underwent successful cyst resection, he was noted to have a suspected recurrence 6 months later. Immediately prior to revision excision, repeat awake flexible fibre-optic laryngoscopy revealed complete resolution of the suspected recurrence. This case underscores the significance of performing a complete upper airway examination, including endoscopic examination, to identify structural and anatomical lesions in older children with SDB.

How to HEEAL: A Patient and Peer-Centric Simulation Curriculum for Medical Error Disclosure.

Introduction: Medical errors are an unfortunate certainty with emotional and psychological consequences for patients and health care providers. No standardized medical curriculum on how to disclose medical errors to patients or peers exists. The novel HEEAL (honesty/empathy/education/apology-awareness/lessen chance for future errors) curriculum addresses this gap in medical education through a multimodality workshop. Methods: This 6-hour, two-part curriculum incorporated didactic and standardized patient (SP) simulation education with rapid cycle deliberate practice (RCDP). The morning focused on provider-patient error disclosure; the afternoon applied the same principles to provider-provider (peer) discussion. Summative simulations with SPs evaluated learners' skill baseline and improvement. Formative simulations run by expert simulation educators used RCDP to provide real-time feedback and opportunities for adjustment. Medical knowledge was measured through pre- and postintervention multiple-choice questions. Learners' confidence and attitude towards medical errors disclosure were surveyed pre- and postintervention with assistance of the Barriers to Error Disclosure Assessment tool, revised with the addition of several questions related to provider-provider disclosure. Results: Fourteen medical students participated in this pilot curriculum. Statistical significance was demonstrated in medical knowledge (p = .01), peer-disclosure skills (p = .001), and confidence in medical error disclosure (p < .001). Although there was improvement in patient-disclosure skills, this did not reach statistical significance (p = .05). Discussion: This curriculum addresses the need for designated training in medical error disclosure. Learners gained knowledge, skills, and confidence in medical error disclosure. We recommend this curriculum for medical students preparing for transition to residency.

Foster Care Involvement Among Youth With Intellectual and Developmental Disabilities.

Importance: Youth with intellectual and developmental disabilities (I/DD) are more likely to be placed in foster care than other youth. Examining the clinical and sociodemographic characteristics of youth with I/DD in the foster care system is critical for identifying disparities and understanding service needs. Objective: To produce a population-level analysis of youth with I/DD in foster care that examines differences in rates of foster care involvement based on race, ethnicity, age, and sex. Design, Setting, and Participants: This cross-sectional study involved all individuals with I/DD 21 years and younger enrolled in Medicaid through foster care in 2016 via data from Transformed Medicaid Statistical Information System (T-MSIS) Analytic Files (TAF) for all 50 US states and Washington, DC. As a key insurer of I/DD services and foster care, Medicaid claims offer a timely population-level analysis. Youth with I/DD were grouped into diagnostic subgroups: autism spectrum disorder (ASD) only, intellectual disability only, or ASD and ID. The data analysis took place from July 2022 to September 2023. Exposure: TAF data contain Medicaid enrollment information by month with a binary indicator of foster care involvement, and eligibility files identify race, ethnicity, age, and sex. Main Outcomes and Measures: The period prevalence of foster care involvement was determined among I/DD youth by diagnostic subgroups using an intersectional approach across race, ethnicity, age, and sex. Logistic regression examined associations between risk for foster care involvement and race, ethnicity, age, and sex. Results: A total of 39 143 youth with I/DD had foster care involvement in 2016. Black youth (adjusted odds ratio [aOR], 1.37; 95% CI, 1.28-1.47) and females (aOR, 1.18; 95% CI, 1.1-1.27) had increased likelihood for foster care involvement. The likelihood for foster care involvement increased with age in all groups relative to the age group 0 to 5 years old. Conclusions and Relevance: This study found that among youth with I/DD, Black youth and females faced higher risk for foster care involvement, and the likelihood of foster care involvement increased with age. There is an urgent need for research that focuses on addressing system-level factors that drive increased risk. Understanding the specific health needs of Black and female youth with I/DD is critical to ensure the formation, implementation, and monitoring of equitable delivery of health services.

Rates of Occult Invasive Disease in Patients With Biopsy-Proven Oral Cavity Squamous Cell Carcinoma in Situ.

Importance: The likelihood that an oral cavity lesion harbors occult invasive disease after biopsy demonstrating carcinoma in situ (CIS) is unknown. While de-escalated treatment strategies may be appealing in the setting of CIS, knowing whether occult invasive disease may be present and its association with survival outcomes would lead to more informed management decisions. Objective: To evaluate rate of occult invasive disease and clinical outcomes in patients with oral cavity CIS. Design, Setting, and Participants: This was a retrospective population-based cohort study using the National Cancer Database and included adults with biopsy-proven oral cavity CIS as the first diagnosis of cancer between 2004 and 2020. Data were analyzed from October 10, 2022, to June 25, 2023. Exposures: Surgical resection vs no surgery. Main Outcomes and Measures: Analyses calculated the rate of occult invasive disease identified on resection of a biopsy-proven CIS lesion. Univariate and multivariate logistic regression with odds ratios and 95% CIs were used to identify significant demographic and clinical characteristics associated with risk of occult invasion (age, year of diagnosis, sex, race and ethnicity, oral cavity subsite, and comorbidity status). Kaplan-Meier curves for overall survival (OS) were calculated for both unresected and resected cohorts (stratified by presence of occult invasive disease). Results: A total of 1856 patients with oral cavity CIS were identified, with 122 who did not undergo surgery (median [range] age, 65 [26-90] years; 48 female individuals [39.3%] and 74 male individuals [60.7%]) and 1458 who underwent surgical resection and had documented pathology (median [range] age, 62 [21-90] years; 490 female individuals [33.6%] and 968 male individuals [66.4%]). Of the 1580 patients overall, 52 (3.3%) were Black; 39 (2.5%), Hispanic; 1365 (86.4%), White; and 124 (7.8%), other, not specified. Among those who proceeded with surgery with documented pathology, 408 patients (28.0%) were found to have occult invasive disease. Higher-risk features were present in 45 patients (11.0%) for final margin positivity, 16 patients (3.9%) for lymphovascular invasion, 13 patients (3.2%) for high-grade invasive disease, and 14 patients (3.4%) for nodal involvement. For those patients with occult disease, staging according to the American Joint Committee on Cancer's AJCC Cancer Staging Manual, eighth edition, was pT1 in 341 patients (83.6%), pT2 in 41 (10.0%), and pT3 or pT4 disease in 26 (6.4%). Factors associated with greater odds of occult invasive disease at resection were female sex, Black race, and alveolar ridge, vestibule, and retromolar subsite. With median 66-month follow-up, 5-year OS was 85.9% in patients who proceeded with surgical resection vs 59.7% in patients who did not undergo surgery (difference, 26.2%; 95% CI, 19.0%-33.4%). Conclusions and Relevance: This cohort study assessed the risk of concurrent occult invasion with biopsy-proven CIS of the oral cavity, demonstrating that 28.0% had invasive disease at resection. Reassuringly, even in the setting of occult invasion, high-risk disease features were rare, and 5-year OS was nearly 80% with resection. The findings support the practice of definitive resection if feasible following biopsy demonstrating oral cavity CIS.

Creating the Global Criminal Justice Survey: A Questionnaire Designed to Gather Perspectives from the Autism Community and Criminal Justice Professionals.

Autistic people's perceptions of their interactions with criminal justice professionals are predominantly negative; however, little is known about the state of interactions on a global scale. To further understanding, a comprehensive stakeholder questionnaire was created. Aspects of reliability and validity including evidence for test content and internal structure were gathered using expert reviews, cognitive interviewing, pilot data collection, and a larger data collection effort (N = 1618). Data was gathered from the autism community through perspectives of parents/caregivers as well as from self-reported autistic adults. Criminal justice professionals included law enforcement officers, corrections professionals, probation and parole officers, forensic psychologists and legal professionals. The scale development process was detailed in order to sufficiently document the initial psychometric evidence and share the steps taken to gain diverse stakeholder input. This study is a critical first step in generating further information to facilitate policy and program development with wide applicability.

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.

Clinical predictors of premature radiotherapy terminations in senior adults with oral cavity and laryngeal carcinoma.

INTRODUCTION: The underlying factors that contribute to early radiotherapy (RT) termination are understudied, especially in the era of hypofractionated treatment regimens. In this retrospective investigation, we examined the characteristics and causes of premature RT terminations in senior adults (>70 years old) with oral cavity (OC) and laryngeal carcinomas. METHODS: Hundred and eighty-eight patients treated with RT ± systemic therapy for OC and laryngeal cancer from 2017 to 2022 were identified. Premature termination was defined as completion of less than 95% of the prescribed RT. Logistic regression analysis was performed to examine factors predictive of premature termination, and survival was determined using the Kaplan-Meier method. RESULTS: Twenty patients (10.6%) experienced premature RT terminations. On regression analysis, ECOG score at initiation of RT was the only covariate studied to be independently associated with premature termination (OR 2.00, 95%CI: [1.21, 3.30], p = 0.007). Three-year overall survival (49.1% vs. 77.3%) was significantly reduced in the termination cohort (p < 0.0001). CONCLUSIONS: This analysis demonstrated over 1 in 10 patients had premature RT termination, which prognosticated inferior survival outcomes. Poor performance status may highlight patients at risk for premature termination and thus identify good candidates for hypofractionated protocols.

Allergy History and Immunotherapy Response in Patients With Recurrent/Metastatic Head and Neck Squamous Cell Carcinoma.

OBJECTIVE: This study examines the association between patient-reported allergy history and immune checkpoint inhibition (ICI) response in patients with recurrent or metastatic head and neck squamous cell carcinoma (RMHNSCC). STUDY DESIGN: Retrospective cohort study. SETTING: Academic tertiary care hospital. METHODS: Data were collected from the electronic medical records on baseline age, sex, allergy history, human papillomavirus status, T-stage, N-stage, smoking status, and survival for patients with and without an allergy history. The primary outcome was ICI response defined as complete or partial response by the RECIST criteria. Chi-square and logistic regression analyses were conducted to compare rates and odds of ICI response. Kaplan-Meier analyses were used to compare survival between groups. RESULTS: Our study included 52 patients with an allergy history and 36 patients without an allergy history. The groups were similar in age, sex, HPV status, smoking status, and T- and N-stage. Patients with an allergy history (17/52, 32.1%) had a greater ICI response rate than patients without allergy history (4/36, 11.1%) (P = .02). After adjusting for HPV, patients with allergies had 3.93 (1.19-13.00) times increased odds of ICI response compared to patients without allergies. The median progression-free survival was 6.0 and 4.2 months for patients with and without an allergy history respectively (log-rank, P = .04). The median overall survival was 25.0 and 11.1 months for patients with and without an allergy history respectively (log-rank, P = .002). CONCLUSION: Patient-reported allergy history was associated with ICI response in patients with RMHNSCC, underscoring the potential clinical utility of allergy history in estimating ICI response.

Front-Line Health Care Workers' COVID-19 Infection Contamination Risks: A Human Factors and Risk Analysis Study of Personal Protective Equipment.

Infectious risks escalate with complex donning and doffing personal protective equipment (PPE) protocols. Recent studies suggest that PPE donning and doffing behaviors that deviate from protocol during PPE reuse compounded the risks of health care worker (HCW) self-contamination. This study quantified the occurrence of behaviors associated with known risks in PPE use and reuse. We conducted a prospective study of emergency department HCWs and video-recorded PPE donning and doffing 5 times in simulated patient encounters. Trained coders recorded HCW behaviors according to an evidence-based guide. All 28 participants deviated from the Centers for Disease Control and Prevention (CDC) sanctioned donning and doffing protocol order, and most were documented to have (92.85%) self-contaminated at least once during each simulated clinical encounter. Behaviors that compounded self-contamination due to PPE reuse were also observed. Wide variation in PPE donning and doffing behaviors was found among front-line, experienced HCWs. Future work is needed to determine which deviations put HCWs at increased risk for accidental self-contamination and what changes are needed to the CDC protocol for protecting HCW from infections.

An investigation into emergency medicine resident cricothyrotomy competency: Is three the magic number?

Objectives: Cricothyrotomy is a high-stakes emergency procedure. Because the procedure is rare, simulation is often used to train residents. The Accreditation Council for Graduate Medical Education (ACGME) requires performance of three cricothyrotomies during residency, but the optimal number of training repetitions is unknown. Additional repetitions beyond three could increase proficiency, though it is unknown whether there is a threshold beyond which there is no benefit to additional repetition. The objective of this study was to establish a minimum number of simulated cricothyrotomy attempts beyond which additional attempts did not increase proficiency. Methods: This was a prospective, observational study conducted over 3 years at the simulation center of an academic emergency medicine residency program. Participants were residents participating in a cricothyrotomy training as part of a longitudinal airway curriculum course. The primary outcome was time to successful completion of the procedure as first-year residents. Secondary outcomes included time to completion as second- and third-year residents. Procedure times were plotted as a function of attempt number. Data were analyzed using descriptive statistics, repeated-measures analysis of variance, and correlation analysis. Preprocedure surveys collected further data regarding procedure experience, confidence, and comfort. Results: Sixty-nine first-year residents participated in the study. Steady improvement in time to completion was seen through the first six attempts (from a mean of 75 to 41 sec), after which no further significant improvement was found. Second- and third-year residents initially demonstrated slower performance than first-year residents but rapidly improved to surpass their first-year performance. Resident mean times at five attempts were faster with each year of residency (first-year 48 sec, second-year 30 sec, third-year 24 sec). There was no statistically significant correlation between confidence and time to complete the procedure. Conclusions: Additional repetition beyond the ACGME-endorsed three cricothyrotomy attempts may help increase proficiency. Periodic retraining may be important to maintain skills.

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.

Impact of comorbidities on outcomes in patients with advanced head and neck cancer undergoing immunotherapy.

OBJECTIVES: To explore the impact of pre-existing comorbidities on immunotherapy response, overall and progression-free survival, and immune-related adverse events (irAEs) of patients with advanced head and neck cancer (HNC) treated with immunotherapy. PATIENTS AND METHODS: Ninety-three patients treated with immunotherapy were identified and stratified into comorbidity absent or present (CCI < 1 and CCI ≥ 1, respectively) cohorts, and clinical outcomes were compared between these two groups. RESULTS: Patients with no comorbidities had longer overall survival (aHR = 2.74, 95% CI [1.18, 6.40], p = 0.02) and progression-free survival (aHR = 2.07, 95% CI [1.03, 4.16], p = 0.04) and a higher tumor response rate (32% in CCI < 1 vs. 14% in CC ≥ 1, p = 0.05). Risk for irAEs was higher in the comorbidity absent group (p = 0.05). CONCLUSION: Comorbidity should be considered as a significant prognostic factor in clinical decision-making for patients with advanced HNC undergoing immunotherapy.

Evaluation and Management of Inflammatory Reactions to Vocal Fold Injection Laryngoplasty with Hyaluronic Acid.

OBJECTIVES: Inflammatory reaction to vocal fold injection laryngoplasty with hyaluronic acid (HA) is a rare condition whose optimal management is not established. In this study, we aim to review the presentation of these reactions and outline an approach for evaluation and management. METHODS: We performed a retrospective review of all patients at our institution who underwent vocal fold injection augmentation with HA during the period extending from August 2018 until October 2022. We then identified patients with postinjection inflammatory reaction and reviewed demographic data, indication for injection, amount of HA injected, setting of procedure, and symptoms. The types of complication, management plan, onset, and time to complete resolution were also recorded. A comprehensive literature search for similar complications was conducted for comparative analysis. Once the available data were aggregated with our institutional experience, we developed an algorithmic approach to manage this condition. RESULTS: We identified 83 patients (124 vocal folds) who underwent vocal fold injection laryngoplasty with HA over a 4-year period. Four patients (4.8%) had a postprocedure inflammatory reaction (5.6% of all vocal folds). Of the four patients, three presented with dyspnea and stridor, while one presented with dysphonia, with onset of symptoms ranging from 24 to 48 hour postinjection. All patients were treated with corticosteroids. For comparative analysis, we identified 24 patients from the literature with reported inflammatory reactions to HA. CONCLUSION: We suggest an algorithmic approach to managing laryngeal inflammation following HA injection. Familiarity with treatment for this rare complication is essential to avoid significant morbidity and achieve optimal outcomes.

Laparoscopic Versus Open Ventriculoperitoneal Shunt Placement: A Non-inferiority Study.

Ventriculoperitoneal shunt (VPS) insertion into the abdominal cavity had been done for decades via an open approach. Recently, the laparoscopic insertion of the peritoneal portion of the shunt has become an option. The aim of this study is to compare outcomes between these two approaches. We performed a single institution retrospective review of 104 consecutive adult patients between 2015 and 2017. Patients had peritoneal catheters placed either via an open approach by the neurosurgical team, or laparoscopically by general surgeons. Patient demographics and outcomes were compared using a non-inferiority analysis. Independent variables in the analysis included patient age, gender, race, BMI, surgery performed, previous VPS placement, previous abdominal procedures, and VPS indication, while dependent variables included length of stay (LOS), estimated blood loss (EBL), occurrence of shunt failure, and postoperative complications. Cohort analysis included 62 open and 42 laparoscopic cases with similar baseline characteristics. In terms of patient outcomes, EBL and hospital stay duration were shown to be non-inferior in the open group as compared to the laparoscopic group. We could not prove non-inferiority based on risk for overall or distal shunt failure. Neurosurgeons may reasonably continue to place peritoneal shunt catheters using a "traditional" method.
