Dental Age Assessment of United States Black and White Children: Performance Reliability of Harris and McKee (1990).

ABSTRACT: Medicolegal authorities use forensic dental age assessment of children to establish a biologic profile to assist in human identification, answer questions related to immigration, and answer questions used to substantiate eligibility for social benefits. The goal of this study was to assess the performance reliability of the child dental age assessment data previously published for White and Black children in the United States. A total of 432 dental panoramic radiographs were obtained from 3 geographic locations in the United States: Memphis, Tennessee, Knoxville, Tennessee, and Saint Louis, Missouri. Radiographs were staged, and the estimated age was calculated using the previously published data. Multiple age assessments were conducted to determine the effect of excluding certain teeth on estimated age. The results indicated estimated ages using the previously published reference data set were accurate and concordant with known chronologic age across the ancestral, sex, and geographic categories. The results also indicated that the known chronologic age fell within one standard deviation of the estimated age more than the statistical expectation for most categories. Excluding canines provided the most accurate estimation of known chronologic age.

Merkel Cell Polyomavirus Antibody Titer Predicts Recurrence-Free Survival.

BACKGROUND: Merkel cell polyomavirus (MCPyV) is associated with the development of Merkel cell carcinoma (MCC). Antibody (MCPyV-Ab) titers may have prognostic implications. This study evaluated the impact of the presence or absence of MCPyV-Ab on the 2-year overall survival (OS) and disease-free survival (DFS) of MCC patients. METHODS: This single-center, IRB-approved, retrospective cohort study evaluated 51 adult patients with MCC from 2014 to 2021 using a prospectively maintained database. Patients were compared by MCPyV-Ab status, and Kaplan-Meier analysis was used to evaluate 2-year OS and DFS. RESULTS: Of the 51 patients, 13 (25.4%) were seropositive, 41 (80.4%) underwent wide excision, 40 (80.0%) received radiotherapy, and 43 (84.3%) received multimodal therapy. The median follow-up period was 15.5 months (range 1-69.5 months). The median 2-year OS of the entire cohort was not reached. The median 2-year OS was not reached for either the seronegative or the seropositive patients. The difference in 2-year OS between the groups was not statistically significant (p = 0.37). Eight patients, all seronegative, were never rendered disease-free and were removed from recurrence analysis. The seropositive patients experienced no recurrences. Of the 30 seronegative patients, 9 (30.0%) experienced recurrence. The median 2-year DFS of the entire cohort was not reached. The median 2-year DFS of the seronegative group was 22.2 months. The 2-year DFS was not reached for the seropositive cohort. Seropositivity conferred a significantly better 2-year DFS than seronegativity (p = 0.04). CONCLUSION: The MCPyV-Ab seropositive patients demonstrated improved 2-year DFS. The seropositive patients showed a strong trend toward improved 2-year OS, although the difference not statistically significant. This study substantiated the value of MCPyV-Ab assessment for MCC.

Epidermis and Enamel: Insights Into Gnawing Criticisms of Human Bitemark Evidence.

Critics describe forensic dentists' management of bitemark evidence as junk science with poor sensitivity and specificity and state that linkages to a biter are unfounded. Those vocal critics, supported by certain media, characterize odontologists' previous errors as egregious and petition government agencies to render bitemark evidence inadmissible. Odontologists acknowledge that some practitioners have made past mistakes. However, it does not logically follow that the errors of a few identify a systemic failure of bitemark analysis. Scrutiny of the contentious cases shows that most occurred 20 to 40 years ago. Since then, research has been ongoing and more conservative guidelines, standards, and terminology have been adopted so that past errors are no longer reflective of current safeguards. The authors recommend a comprehensive root analysis of problem cases to be used to determine all the factors that contributed to those previous problems. The legal community also shares responsibility for some of the past erroneous convictions. Currently, most proffered bitemark cases referred to odontologists do not reach courts because those forensic dentists dismiss them as unacceptable or insufficient for analysis. Most bitemark evidence cases have been properly managed by odontologists. Bitemark evidence and testimony remain relevant and have made significant contributions in the justice system.

Recurrent atypical fibroxanthoma with satellite metastasis.

Atypical fibroxanthoma (AFX) is a cutaneous neoplasm of uncertain etiology that develops on sun-exposed regions of elderly males. It is widely considered to act indolently, despite its highly malignant cytologic features. Reports of metastatic AFX are very rare, and recurrence is uncommon. We report a case of recurrent AFX exhibiting a pattern of satellite metastasis followed by evidence of regional lymph node metastasis. A 76-year-old male with prior occupational and therapeutic radiation exposure and numerous squamous cell carcinomas had AFX of the left vertex scalp limited to the dermis completely removed by micrographic surgery. Twenty months later, multiple lesions appeared at the site of previous surgery. Imaging revealed no metastases or calvarial involvement. Wide local excision showed multiple well-defined nodules involving dermis and subcutis. The primary and recurrent neoplasms were similar and composed of pleomorphic epithelioid and spindled cells with marked nuclear atypia, hyperchromasia and mitotic activity. Immunohistochemistry was positive for CD10, procollagen1 and vimentin and negative for cytokeratins AE1/AE3, cytokeratins 5/6, 34ßE12, MNF116, p63 CD31, Mart1, smooth muscle actin, desmin, S100 and CD34. Forty-eight months after removal of the primary, left intraparotid and posterior triangle lymph nodes are suspected to be involved by metastasis using clinical and positron emission tomography/ computed tomography examinations.

Forensic Dental Age Estimation: An Overview.

Forensic age estimation is a scientific process that estimates an individual's true chronologic age by assessing skeletal and dental development and maturation. Although human growth and maturation is unique to each individual, dental techniques for estimating age are currently considered the best in assessing true chronologic age particularly during the age range when the dentition is undergoing morphologic development. This article reviews the principles, methodology and commonly used techniques in forensic age estimation cases.

Higher degree of impostor characteristics relates to lower self-perceived teaching ability and emotional intelligence.

BACKGROUND: Emotional intelligence (EI) has been previously associated with teaching ability and impostor phenomenon (IP) in medical education; however, studies have demonstrated mixed findings and have largely focused on trainees only. Therefore, we sought to explore the potential association between the degree of IP characteristics, EI and teaching ability in obstetrics and gynaecology (Ob/Gyn) faculty physicians. METHODS: A cross-sectional, survey-based pilot study was completed at a single academic institution. Ob/Gyn attending (faculty) physicians were queried using surveys related to IP, EI and teaching ability. Resident (trainee) physicians also completed anonymous evaluations of faculty teaching ability. FINDINGS: The degree of IP characteristics correlated negatively with self-perceived teaching ability, with no significant differences in resident assessment of faculty teaching. IP also correlated negatively with EI. Although there were no statistically significant differences in resident assessment of teaching ability based on EI, both EI and IP demonstrated inverse relationships to faculty assessment of teaching ability compared with resident assessment. CONCLUSION: IP appears to relate to lower perceived teaching ability in Ob/Gyn faculty that does not correspond to resident evaluation of teaching performance. The demonstrated negative correlation between the degree of impostor characteristics and EI suggests that EI could potentially play a protective role in the development of IP and burnout, as well as influence teaching. This relationship may have implications for faculty willingness to continue in academic medicine.

Odontogenic ameloblast-associated protein (ODAM) inhibits growth and migration of human melanoma cells and elicits PTEN elevation and inactivation of PI3K/AKT signaling.

BACKGROUND: The Odontogenic Ameloblast-associated Protein (ODAM) is expressed in a wide range of normal epithelial, and neoplastic tissues, and we have posited that ODAM serves as a novel prognostic biomarker for breast cancer and melanoma. Transfection of ODAM into breast cancer cells yields suppression of cellular growth, motility, and in vivo tumorigenicity. Herein we have extended these studies to the effects of ODAM on cultured melanoma cell lines. METHODS: The A375 and C8161 melanoma cell lines were stably transfected with ODAM and assayed for properties associated with tumorigenicity including cell growth, motility, and extracellular matrix adhesion. In addition, ODAM-transfected cells were assayed for signal transduction via AKT which promotes cell proliferation and survival in many neoplasms. RESULTS: ODAM expression in A375 and C8161 cells strongly inhibited cell growth and motility in vitro, increased cell adhesion to extracellular matrix, and yielded significant cytoskeletal/morphologic rearrangement. Furthermore, AKT activity was downregulated by ODAM expression while an increase was noted in expression of the PTEN (phosphatase and tensin homolog on chromosome 10) tumor suppressor gene, an antagonist of AKT activation. Increased PTEN in ODAM-expressing cells was associated with increases in PTEN mRNA levels and de novo protein synthesis. Silencing of PTEN expression yielded recovery of AKT activity in ODAM-expressing melanoma cells. Similar PTEN elevation and inhibition of AKT by ODAM was observed in MDA-MB-231 breast cancer cells while ODAM expression had no effect in PTEN-deficient BT-549 breast cancer cells. CONCLUSIONS: The apparent anti-neoplastic effects of ODAM in cultured melanoma and breast cancer cells are associated with increased PTEN expression, and suppression of AKT activity. This association should serve to clarify the clinical import of ODAM expression and any role it may serve as an indicator of tumor behavior.

The impact of age on morbidity and mortality following esophagectomy for esophageal cancer.

BACKGROUND: In patients with esophageal cancer, treatment decisions often involve a balance between a high-risk procedure and the chance for long-term benefit. The decision can be additionally challenging for elderly patients since some studies have reported an increased incidence of morbidity and mortality in this age group, and data are not clear on the overall benefit of multimodality therapy. METHODS: To investigate the management and outcomes associated with esophagectomy in elderly patients with esophageal cancer, we performed a review of the literature as well as an analysis of our own institutional data, with a focus on the impact of age on surgical outcomes. We examined type of surgery, neoadjuvant and adjuvant therapy, postoperative complications, length of hospitalization, and mortality as variables in elderly patients with esophageal cancer. RESULTS: When assessing the impact of age on the success of esophagectomy, several studies have concluded that advanced age itself is not a predictor of outcomes as much as associated comorbidities are. Our own experience suggests that age is not associated with adverse outcomes when controlling for patient comorbidities. This finding is similar to data reported elsewhere. CONCLUSIONS: When considering treatment for patients of advanced age, the risks of treatment should be compared with the survival benefits of the therapy prescribed, taking into account additional factors such as poor performance status, existing comorbidities, and residual tumor following neoadjuvant therapy. Many reports, as well as our own experience, have concluded that when adjusted for comorbidities, patient age does not significantly affect outcomes.

Questions of logic in Atlas methods of dental age estimation.

PURPOSE: To review aspects of the underlying methodological procedures in Atlas Methods of Dental Age Estimation (DAE) research publications. Attention is paid to issues of Reference Data supporting the Atlases, details of analytic procedures in the development of the Atlases, the statistical reporting of results of Age Estimation (AE), the problems of expressing uncertainty, and the viability of conclusions in the reporting of DAE studies. METHODS: Research reports utilizing Dental Panoramic Tomographs for creating Reference Data Sets (RDS) were studied to unravel the processes of creating Atlases with a view to determining the appropriate procedures for developing numerical RDS and compiling them into an Atlas format to enable DAE of child subjects without birth records. RESULTS: The five different Atlases reviewed gave several different results in terms of AE. The possible causes of this were discussed - namely inadequate representation of Reference Data (RD) and lack of clarity in expressing uncertainty. It is suggested that the method of compiling Atlases needs to be more clearly defined. The yearly intervals described by some of the Atlases fails to take account of the Uncertainty of Estimates which is usually slightly greater than ±2½ years. CONCLUSION: The review of published Atlas design papers in the field of DAE shows a number of different study designs, statistical procedures, and presentational styles, particularly with regard to the statistical procedures and findings. These show that Atlas methods can only be accurate to what amounts to at best a year. RECOMMENDATIONS: Atlas methods lack the accuracy and precision of other methods of AE an example of which is the Simple Average Method (SAM).1 This inherent lack of accuracy must be taken into account when using Atlas methods for AE.

Validating a Novel Emotional Intelligence Instrument for Resident Physicians.

To construct and validate a scale of emotional intelligence (EI) for the medical field, n = 80 resident physicians responded to a 69-item self-report measure during the pilot phase of development of the Scale of Emotional Functioning: Medicine (SEF:MED). Based on multiple-phase item and structural analyses, a final 36-item version was created based on data from n = 321 respondent residents. Initially exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) supported the expected three-factor solution as did additional CFA from a second sample of n = 113 participants. Internal consistency reliabilities obtained from the original n = 321 residents for the three SEF:MED subscales of Interpersonal Skills (IS), Emotional Awareness (EA), and Emotional Management (EM) were 0.81, 0.82, and 0.84, respectively. Alphas for the second CFA data set were 0.89, 0.87, and 0.88 for IS, EM, and EA, respectively. In addition, the SEF:MED was validated by comparing it to related measures (i.e., the Profile of Emotional Competence (PEC) and the Maslach Burnout Inventory-Human Services Survey for Medical Personnel [MBI-HSS (MP)]); Correlation coefficients between the Total EI composite on the SEF:MED and the PEC global scales ranged from r = 0.64 to 0.68. Finally, correlation coefficients from the Total EI composite on the SEF:MED significantly related to the MBI-HSS (MP) Emotional Exhaustion (EE), Depersonalization (DP), and Personal Accomplishment (PA) scales (r = -0.50, -0.44, and 0.52, respectively). The SEF:MED may provide useful data to physicians and other medical professionals as they consider their own well-being and how it may affect care of their patients.

Therapeutic Value of Sentinel Lymph Node Biopsy in Patients With Melanoma: A Randomized Clinical Trial.

Importance: Sentinel lymph node (SLN) biopsy is a standard staging procedure for cutaneous melanoma. Regional disease control is a clinically important therapeutic goal of surgical intervention, including nodal surgery. Objective: To determine how frequently SLN biopsy without completion lymph node dissection (CLND) results in long-term regional nodal disease control in patients with SLN metastases. Design, Setting, and Participants: The second Multicenter Selective Lymphadenectomy Trial (MSLT-II), a prospective multicenter randomized clinical trial, randomized participants with SLN metastases to either CLND or nodal observation. The current analysis examines observation patients with regard to regional nodal recurrence. Trial patients were aged 18 to 75 years with melanoma metastatic to SLN(s). Data were collected from December 2004 to April 2019, and data were analyzed from July 2020 to January 2022. Interventions: Nodal observation with ultrasonography rather than CLND. Main Outcomes and Measures: In-basin nodal recurrence. Results: Of 823 included patients, 479 (58.2%) were male, and the mean (SD) age was 52.8 (13.8) years. Among 855 observed basins, at 10 years, 80.2% (actuarial; 95% CI, 77-83) of basins were free of nodal recurrence. By univariable analysis, freedom from regional nodal recurrence was associated with age younger than 50 years (hazard ratio [HR], 0.49; 95% CI, 0.34-0.70; P < .001), nonulcerated melanoma (HR, 0.36; 95% CI, 0.36-0.49; P < .001), thinner primary melanoma (less than 1.5 mm; HR, 0.46; 95% CI, 0.27-0.78; P = .004), axillary basin (HR, 0.61; 95% CI, 0.44-0.86; P = .005), fewer positive SLNs (1 vs 3 or more; HR, 0.32; 95% CI, 0.14-0.75; P = .008), and SLN tumor burden (measured by diameter less than 1 mm [HR, 0.39; 95% CI, 0.26-0.60; P = .001] or less than 5% area [HR, 0.36; 95% CI, 0.24-0.54; P < .001]). By multivariable analysis, younger age (HR, 0.57; 95% CI, 0.39-0.84; P = .004), thinner primary melanoma (HR, 0.40; 95% CI, 0.22-0.70; P = .002), axillary basin (HR, 0.55; 95% CI, 0.31-0.96; P = .03), SLN metastasis diameter less than 1 mm (HR, 0.52; 95% CI, 0.33-0.81; P = .007), and area less than 5% (HR, 0.58; 95% CI, 0.38-0.88; P = .01) were associated with basin control. When looking at the identified risk factors of age (50 years or older), ulceration, Breslow thickness greater than 3.5 mm, nonaxillary basin, and tumor burden of maximum diameter of 1 mm or greater and/or metastasis area of 5% or greater and excluding missing value cases, basin disease-free rates at 5 years were 96% (95% CI, 88-100) for patients with 0 risk factors, 89% (95% CI, 82-96) for 1 risk factor, 86% (95% CI, 80-93) for 2 risk factors, 80% (95% CI, 71-89) for 3 risk factors, 61% (95% CI, 48-74) for 4 risk factors, and 54% (95% CI, 36-72) for 5 or 6 risk factors. Conclusions and Relevance: This randomized clinical trial was the largest prospective evaluation of long-term regional basin control in patients with melanoma who had nodal observation after removal of a positive SLN. SLN biopsy without CLND cleared disease in the affected nodal basin in most patients, even those with multiple risk factors for in-basin recurrence. In addition to its well-validated value in staging, SLN biopsy may also be regarded as therapeutic in some patients. Trial Registration: ClinicalTrials.gov Identifier: NCT00297895.

Emotional Intelligence and Burnout Related to Resident-Assessed Faculty Teaching Scores.

OBJECTIVE: Emotional intelligence (EI) is associated with job success in multiple fields, in part, because EI may mitigate stress and burnout. Research suggests these relationships may include teaching. Our purpose is to further explore the relationships between EI, burnout, and teaching for faculty surgeons. DESIGN: With IRB approval, surgical faculty were offered the opportunity to complete personal demographics, the Maslach Burnout Inventory, the SETQ-SMART assessment of teaching ability, and the SEF:MED self-assessment of emotional intelligence. Surgical residents rated faculty teaching ability using the SETQ-SMART SETTING: A medium-sized academic medical center in the Southeast approved to graduate 6 residents per year. PARTICIPANTS: ACGME surgical faculty and general surgical residents PGY1 to PGY5 including preliminary residents, were given the opportunity to participate. RESULTS: Faculty self-assessed teaching scores were significantly different from resident scores for nine (60%) faculty; three (33%) overrated their and 6 (67%) under rated their overall teaching ability, relative to resident ratings. The 3 SEF:MED scales correlated low-moderate to strongly with the SETQ-OTS: IS (r = 0.41, p = 0.13), EM (r = 0.67, p < 0.01), and EA (r = 0.43, p = 0.11). Overall, 8(53%) faculty scored moderate to high on at least 1 of the 3 MBI subscales. Overall self-rated faculty teaching scores correlated negatively with higher EE and DP and positively with PA (r = -0.08, -0.21, and 0.52, p = 0.047; respectively). EI negatively correlated with MBI-EE and DP and positively with PA (r = -0.31, -0.18, 0.45, respectively), though due to the small sample none reach statistical significance with alpha set to 0.05. CONCLUSIONS: In this pilot study, EI is positively correlated to surgical faculty members' teaching ability. Burnout was less strongly correlated with resident-assessed faculty teaching scores, but with similar trends. Finally, EI was correlated with MBI EE, DP, and PA as expected given the literature in other fields. Expanded study is warranted.

Integrating 31-Gene Expression Profiling With Clinicopathologic Features to Optimize Cutaneous Melanoma Sentinel Lymph Node Metastasis Prediction.

National guidelines recommend sentinel lymph node biopsy (SLNB) be offered to patients with > 10% likelihood of sentinel lymph node (SLN) positivity. On the other hand, guidelines do not recommend SLNB for patients with T1a tumors without high-risk features who have < 5% likelihood of a positive SLN. However, the decision to perform SLNB is less certain for patients with higher-risk T1 melanomas in which a positive node is expected 5%-10% of the time. We hypothesized that integrating clinicopathologic features with the 31-gene expression profile (31-GEP) score using advanced artificial intelligence techniques would provide more precise SLN risk prediction. METHODS: An integrated 31-GEP (i31-GEP) neural network algorithm incorporating clinicopathologic features with the continuous 31-GEP score was developed using a previously reported patient cohort (n = 1,398) and validated using an independent cohort (n = 1,674). RESULTS: Compared with other covariates in the i31-GEP, the continuous 31-GEP score had the largest likelihood ratio (G2 = 91.3, P < .001) for predicting SLN positivity. The i31-GEP demonstrated high concordance between predicted and observed SLN positivity rates (linear regression slope = 0.999). The i31-GEP increased the percentage of patients with T1-T4 tumors predicted to have < 5% SLN-positive likelihood from 8.5% to 27.7% with a negative predictive value of 98%. Importantly, for patients with T1 tumors originally classified with a likelihood of SLN positivity of 5%-10%, the i31-GEP reclassified 63% of cases as having < 5% or > 10% likelihood of positive SLN, for a more precise, personalized, and clinically actionable SLN-positive likelihood estimate. CONCLUSION: These data suggest the i31-GEP could reduce the number of SLNBs performed by identifying patients with likelihood under the 5% threshold for performance of SLNB and improve the yield of positive SLNBs by identifying patients more likely to have a positive SLNB.

Gene expression profiling of colorectal mucinous adenocarcinomas.

PURPOSE: Although mucinous adenocarcinomas represent 6% to 19% of all colorectal adenocarcinomas, little is known about the genome-wide alterations associated with this malignancy. We have sought to characterize both the gene expression profiles of mucinous adenocarcinomas and their clinicopathologic features. METHODS: Tumors from 171 patients with primary colorectal cancer were profiled using the Affymetrix HG-U133Plus 2.0 GeneChip with characterization of clinicopathologic data. Gene ontology software was used to identify altered biologic pathways. RESULTS: Twenty (11.7%) mucinous adenocarcinomas and 151 (89.3%) nonmucinous adenocarcinomas were identified. Mucinous adenocarcinomas were more likely to be diagnosed with lymph node (LN) metastases (75% vs 51%, P = .04) and at a more advanced stage (85% vs 54%, P = .006) but long-term survival (5-y survival 58.9% vs 58.7%, P = NS) was similar. Mucinous adenocarcinomas displayed 182 upregulated and 135 downregulated genes. The most upregulated genes included those involved in cellular differentiation and mucin metabolism (eg, AQP3 + 4.6, MUC5AC +4.2, MUC2 + 2.8). Altered biologic pathways included those associated with mucin substrate metabolism (P = .002 and .02), amino acid metabolism (P = .02), and the mitogen-activated protein kinase cascade (P = .02). DISCUSSION: Using gene expression profiling of mucinous adenocarcinomas, we have identified the differential upregulation of genes involved in differentiation and mucin metabolism, as well as specific biologic pathways. These findings suggest that mucinous adenocarcinomas represent a genetically distinct variant of colorectal adencarcinoma and have implications for the development of targeted therapies.

Clinical integration of picture archiving and communication systems with pathology and hospital information system in oncology.

The complexity of our current healthcare delivery system has become an impediment to communication among caregivers resulting in fragmentation of patient care. To address these issues, many hospitals are implementing processes to facilitate clinical integration in an effort to improve patient care and safety. Clinical informatics, including image storage in a Picture Archiving and Communication System (PACS), represents a tool whereby clinical integration can be accomplished. In this study, we obtained intraoperative photographs of 19 cases to document clinical stage, extent of disease, disease recurrence, reconstruction/grafting, intraoperative findings not identified by preoperative imaging, and site verification as part of the Universal Protocol. Photographs from all cases were stored and viewed in PACS. Images from many of the cases were presented at our interdepartmental cancer conferences. The stored images improved communication among caregivers and preserved pertinent intraoperative findings in the patients' electronic medical record. In the future, pathology, gastroenterology, pulmonology, dermatology, and cardiology are just a few other subspecialties which could accomplish image storage in PACS. Multidisciplinary image storage in a PACS epitomizes the concept of clinical integration and its goal of improving patient care.

Observational study of talimogene laherparepvec use in the anti-PD-1 era for melanoma in the US (COSMUS-2).

AIM: Talimogene laherparepvec (T-VEC) is an intralesional therapy for unresectable, metastatic melanoma. T-VEC real-world use in the context of anti-PD1-based therapy requires further characterization. MATERIALS & METHODS: A retrospective review of T-VEC use from 1 January 2017 and 31 March 2018 for melanoma patients was conducted at seven US institutions. RESULTS: Among 83 patients, three categories of T-VEC and anti-PD-1 therapy were identified: T-VEC used without anti-PD-1 (n = 29, 35%), T-VEC after anti-PD-1-based therapy (n = 22, 27%) and concurrent T-VEC and anti-PD-1-based therapy (n = 32, 39%). 25% of patients discontinued T-VEC therapy due to no remaining injectable lesions, 37% discontinued T-VEC due to progressive disease. Discontinuation of T-VEC did not differ by anti-PD-1-based therapy use or timing. CONCLUSION: In real-world settings, T-VEC may be used concurrently with or after anti-PD-1-based therapy.

Optimal Pain Control after Outpatient Surgery for Cutaneous Malignancies.

Postoperative pain managed with opioids has contributed to the opioid crisis through overprescribing practices. We assessed opioid-prescribing habits and their use by patients undergoing surgery for cutaneous malignancies. An Institutional Review Board-approved retrospective analysis was conducted for patients who underwent skin cancer resection between January 2018 and June 2018. Data were collected from the electronic medical record, and opioid-related data were collected from patient interviews and state registries. There were 120 study participants (42 females and 78 males) with a median age of 67 years (range, 21-94 years). All received preincision local anesthetic: 64 had liposomal bupivacaine (LB) (53%) and 56 had non-LB bupivacaine (47%). Most participants (n = 88) used 0 opioids (73%), including 43 LB-anesthetic (67%) and 45 non-LB-anesthetic (80%). No significance was seen between those with a diagnosis of chronic pain, narcotic tolerance, an area of resection, and nodal sampling groups in opioid use. Four patients (3%) requested a refill. Of 105 prescriptions written for opioids, 99 had leftover opioids for an overprescribing rate of 94 per cent. This study suggests pain after skin cancer surgery is manageable with very limited opioid requirements. Our results support prescribing no more than five opioid tablets for postoperative pain control in patients undergoing resection for skin malignancies.

Human Acellular Dermal Matrix Is a Viable Alternative to Autologous Skin Graft in Patients with Cutaneous Malignancy.

Skin substitutes have shown success in complex wound reconstruction. We evaluate the use of a human acellular dermal matrix (ADM) as a viable alternative to autologous skin grafting for defects secondary to skin cancer excision. An institutional review board-approved, retrospective review of ADM-reconstructed defects secondary to skin cancer excision between 2012 and 2018 was conducted. ADM was indicated in patients with preclusive factors for general anesthesia, protracted procedure time, reluctance for additional donor site wound, and personal choice. We reviewed defect characteristics, healing time, postoperative outcomes, and patient demographics. The 228 participants (151 males, 77 females) had a median age of 72 years (range, 29-95 years), with melanoma diagnosed in 113 (49.6%), squamous cell carcinoma in 61 (26.8%), and basal cell carcinoma in 28 (12.2%) patients. The median interval to complete epidermal coverage was 42 days, with graft failure evident in six patients (2.6%). ADM is a viable, low-morbid alternative for reconstruction of defects secondary to skin cancer excision, with no donor site morbidity. With exception to complete healing time, outcomes are similar to those of autologous grafting.
