RESUMO
BACKGROUND: Full thickness defects of the ala, soft triangle, and nasal tip involving the nasal lining have traditionally been repaired with the three-stage folded paramedian forehead flap (FPFF), with a cartilage graft for support. For similar defects, the authors utilize the two-stage FPFF without cartilaginous support which provides reproducible functional and aesthetic results. Objective: To describe the authors’ experience with the two-stage FPFF, including outcomes, complications, and design modifications to enhance functional and aesthetic success. Methods: An IRB-approved retrospective database review of FPFF was performed at two sites. Using postoperative photographs, outcomes were assessed by blinded non-investigator dermatologist raters using a modified observer scar assessment scale. RESULTS: Thirty-five patients were reconstructed using the two-stage FPFF without cartilage grafts. Subjective assessment of scar vascularity, pigment, relief, and thickness by 3 independent reviewers yielded an overall cosmesis score of 8.4±1.9 (out of 40). CONCLUSION: The two-stage FPFF without cartilage grafts is a reliable, cosmetically elegant repair that can provide optimal functional and aesthetic results for complex unilateral distal nose defects.J Drugs Dermatol. 2024;23(4): doi:10.36849/JDD.7358.

BACKGROUND: Mohs micrographic surgery (MMS) for cutaneous melanoma has demonstrated higher cure rates, lower local recurrence rates, and improved survival compared with wide local excision (WLE). However, factors affecting referrals by general dermatologists for MMS of head and neck melanoma (HNM) are unknown. OBJECTIVE: To elucidate referral factors and treatment perspectives of general dermatologists regarding MMS for melanoma in situ (MIS)/lentigo maligna (LM) and early-stage melanoma on the head and neck. MATERIALS AND METHODS: A cross-sectional analysis was performed using survey responses of general dermatologists with membership in the American Academy of Dermatology . RESULTS: A total of 231 and 132 of the 402 responding general dermatologists routinely referred melanoma in situ MIS/LM and early invasive melanoma for MMS, respectively. Lack of local access to a Mohs surgeon was the most common deterring reason for MIS/LM referral to MMS, whereas the preference for WLE was the most common deterring reason for early invasive melanoma. CONCLUSION: Lack of local access to a Mohs surgeon treating HNM with MMS is the primary barrier in referrals to Mohs surgeons for MIS and LM. Among general dermatologists, WLE is preferred for early invasive HNM.

BACKGROUND: Tranexamic acid (TXA) is increasingly being used to prevent hemorrhagic complications after dermatologic surgery. Interpolated flap repairs following Mohs micrographic surgery are at risk for increased bleeding events and unplanned health care utilization, particularly among patients on antithrombotic medication. OBJECTIVE: To assess bleeding events after interpolated flap repair in patients receiving TXA compared with those who did not. MATERIALS AND METHODS: A retrospective review identified interpolated flap repairs in a 5-year period. Hemorrhagic complications were analyzed, defined as major bleeding events, which included all unplanned medical visits, and minor bleeding events, which included any unplanned patient phone calls or messages through electronic medical record. RESULTS: One hundred fifteen patients had interpolated flap repair during the 5-year period, of which 21 (18.3%) received TXA postprocedure. Twenty-seven bleeding events were identified in the non-TXA group compared with 1 event in the TXA-treated group. Patients who received TXA were less likely to have had a bleeding event (28.7% vs 4.8%, p < .01). CONCLUSION: Patients undergoing interpolation flap repair were less likely to experience a bleeding event after subcutaneous injection of TXA.

BACKGROUND: The number of skin substitutes (SS) available for wound care management has increased markedly in the last few decades. This presents a challenge as dermatologists attempt to determine the appropriate setting for a skin substitute use. OBJECTIVE: This is a practical review of SS used in dermatologic surgery to assist clinicians in their selection of SS by providing information about the efficacy, risk, availability, shelf-life, and relative cost of the available options. METHODS AND MATERIALS: Relevant data were identified through a search of PubMed, a manual search of relevant company websites, a manual search of the reference sections of relevant papers, and communicating with subject experts. RESULTS: SS can be divided into 7 categories based on composition: amnion, cultured epithelial autograft, acellular allograft, cellular allografts, xenografts, composites, and synthetics. These groups offer unique benefits and disadvantages that are outlined in the manuscript and tables. CONCLUSION: Considerations of the characteristics, settings of use, and efficacies of SS may allow more effective wound care and the potential for faster healing times. Additional studies are needed to evaluate and compare the healing benefits of these substitutes. Trials comparing the efficacy of each of the common SS vs each other and granulation are needed.

BACKGROUND: Investigation of tools used for candidate selection as predictors of future performance in medical education has been primarily undertaken within the undergraduate setting, but little is known about the selection to medical specialist programs. This retrospective longitudinal study aims to explore correlations between selection tools and the performance of trainees enrolled in the Australasian College of Dermatologists (ACD), the accredited specialist medical college for training in dermatology in Australia. METHODS: Data were collected from consecutive cohorts of ACD trainees commencing from 2007 to 2015. Predictive variables were trainee demographics and selection tools (prior academic qualification; research experience; clinical experience; curriculum vitae [CV] rating; interview scores). The outcome variables were exam performance. First Year ([Pharmacology and Clinical Sciences] and Fellowship Exam [Written, Clinical, and Overall Score]). Statistical analyses included: descriptive statistics summaries; bivariate correlation of selection criteria and demographic data with exam performance; and linear regression analysis to identify predictors of exam performance. RESULTS: Demographic analysis (N = 172) showed that 64% of trainees were female, the average age was 30.5 years (± 3.47) and trainees living in high socioeconomic status (SES) areas were over-represented. Using Pearson correlation analysis, interview scores were significantly positively correlated with First Year Pharmacology results (p = 0.018), Fellowship Written results (p = 0.002), and Fellowship Overall Scores (p = 0.006). First Year Pharmacology Exam performance was most highly correlated with Fellowship Exam performance (p = 0.000). No association was identified between exam performance and gender, SES, prior academic qualification, research experience or CV rating. Linear regression analysis showed that interview score (p = 0.012), entry age (p = 0.026) and First Year Pharmacology score (p = 0.002) were predictors of Fellowship exam performance. CONCLUSION: These results suggest that the comprehensive selection tools used by ACD are effective, with interviews being a highly valid tool linked to exam performance. These findings have important practical implications for assessing the selection process in specialist dermatology training.

BACKGROUND: Suture removal after surgery is low risk; however, it is often performed by a medical provider. The current SARS-CoV-2 pandemic has forced providers to assess means of reducing in-person contact. OBJECTIVE: To determine whether patients undergoing Mohs surgery are willing and successful with home suture removal. MATERIALS AND METHODS: A prospective study was performed with patients undergoing Mohs surgery. Before their surgery, patients were assessed for their willingness to remove sutures before and after viewing educational material. Patients who were willing to attempt removal were contacted after expected suture removal date to verify success and assess their experience. RESULTS: One hundred fifty patients were enrolled in the study. 90.1% were willing to attempt home suture removal. Patients were more willing ( p = .003), more confident ( p = .024), and had lower anxiety ( p = .049) with removal after viewing educational resources. Patients with a history of suture removal were more likely to attempt removal after their procedure ( p = .036). Ninety-seven percent of patients who were willing to attempt suture removal were successful. There were no major complications with removal. CONCLUSION: Patients were overwhelmingly successful with suture removal after an educational intervention. Providers should consider providing this option after surgical procedures when clinically appropriate.

Defects involving the glabella and nasal root require an optimal cosmetic outcome due to its critical position in the mid-face. Glabellar defects often involve multiple cosmetic subunits, hair variations, and various skin thicknesses (forehead superiorly, eyebrows / eyelids laterally, nasal root and dorsum inferiorly), further complicating the reconstruction. The eyebrows and natural concavity of this area must be preserved if possible. Repair options in this location vary by personal preference and experience rather than literature-based outcomes. Key considerations include the location of the defect (glabella vs nasal root +/- brow +/- medial canthus), the position of the defect (midline or off-center) and the texture/thickness of the skin (thick glabellar skin or thin skin of medial canthus). The rich blood supply in this area has made local flaps the preferred option for moderate to large defects. However, two pitfalls for local flaps are pincushioning resulting in a “bull nose” and the possibility of causing synophrys. Often, a combination of flaps, grafts, and/or primary closures are necessary to adequately close large glabellar/nasal root defects. There is a paucity of literature for reconstructive options of the glabella and nasal root, and in the authors’ experience, even experienced surgeons struggle to decide on these. We present a series of reconstructive approaches for the majority of moderate to large cutaneous glabellar and nasal root defects with excellent functional and aesthetic results.

BACKGROUND: At the onset of the COVID-19 pandemic, many Mohs micrographic surgeries (MMS) were delayed over concerns for propagating further infectious spread and scarcity of medical resources. OBJECTIVE: To assess the impact of the pandemic on MMS and the treatment of skin cancer Methods and Materials: An electronic survey was sent to fellowship trained Mohs surgeons to assess patient outcomes, practice viability, and physician sentiment related to performing MMS during the COVID-19 pandemic. RESULTS: Of the 303 respondents, 82% reported declines in case volume for at least 3 months, and average case difficulty increased for 69% of surgeons following these delays. Instances of local tumor spread following delays were seen by 69% of respondents, and 20% noted cases of regional or systemic metastasis. Only 8 cases of staff testing positive (and 7 cases of patients) were reported, and 97% of respondents felt comfortable performing MMS during the pandemic. Private practice surgeons more often viewed practice restriction recommendations negatively initially (42% vs 26% in academics, P=0.03) and in hindsight (63% vs 36% in academics, P<0.001). CONCLUSIONS: Mohs surgeon’s ability to minimize spread of COVID-19 during routine patient care, alongside potential risks of delaying treatment of skin cancers, should be considered in future recommendations for patient care.

BACKGROUND: Direct oral anticoagulants (DOACs), such as apixaban, rivaroxaban, and dabigatran, are increasingly being used to provide prophylaxis and treatment for arterial and venous thromboembolism. Multiple procedural subspecialties have implemented guidelines detailing time frames for perioperative DOAC interruption; however, the impact of perioperative DOAC interruption in patients undergoing dermatologic surgery is currently unknown, and evidence-based guidelines are lacking. OBJECTIVE: To assess the 30-day postoperative rate of thrombotic complications (ischemic stroke, transient ischemic attack, systemic embolism, deep vein thrombosis [DVT] and pulmonary embolism) in patients with nonvalvular atrial fibrillation (AF) or a history of DVT who underwent perioperative DOAC interruption during dermatologic surgery. METHODS: A retrospective medical record review was performed of all patients with AF or a history of DVT who underwent perioperative DOAC interruption during dermatologic surgery at Advanced Dermatologic Surgery and the University of Kansas Medical Center between January 1, 2016, and August 31, 2020. RESULTS: Among 806 operations, comprising 750 Mohs micrographic operations (93.1%) and 56 excisions (6.9%), 1 patient (0.14% of patients with AF) sustained a transient ischemic attack and 2 patients (0.25% of all patients) sustained minor bleeding complications during the 30-day postoperative period. CONCLUSION: Perioperative DOAC interruption appears to be safe and efficacious in dermatologic surgery.

BACKGROUND: Patients who understand their diagnosis and treatment are more likely to be satisfied with their care and more compliant with treatment. Dermatologic surgery is a specialized field with associated jargon that many patients may not understand. OBJECTIVE: The aim of the study was to assess patient understanding of dermatology medical terminology. METHODS: This was a single-blinded study conducted with patients 18 years and older from an academic dermatology clinic surveying patients on 12 terms that are frequently used in dermatologic surgery. Participants rated their level of confidence in their understanding of each term using a 5-point Likert scale, followed by explaining the definition of the term. 3 blinded physicians graded each participant’s definition using a 5-point scale of accuracy of understanding, designed to mimic the Likert scale. RESULTS: A total of 200 respondents completed the survey (96% response rate). The average term perceived understanding was 3.90 ±0.66, the average term accuracy was 3.26±0.93. Patients overestimated their understanding 44% of the time, and underestimated their knowledge 17% of the time. The terms with the lowest respondent confidence were the terms secondary intention, Mohs, and flaps. The terms with the lowest respondent accuracy was secondary intention, defect, and Mohs surgery. CONCLUSION: There is a gap in knowledge in commonly used dermatologic surgery terms among patients. Certain demographics appear to be more at risk for not understanding medical jargon or overestimating their understanding of terms. Obtaining these patient demographics may help to identify patients needing additional education regarding dermatologic surgery. J Drugs Dermatol. 2021;20(11):1252-1254. doi:10.36849/JDD.6174.

BACKGROUND: Reconstruction of surgical defects on the dorsal finger can be challenging because of a lack of adjacent tissue reservoirs, poor laxity, and often thin, atrophic skin surrounding the defect. OBJECTIVE: To present reconstructive options for cutaneous dorsal finger defects. METHODS: We describe our five preferred approaches to reconstructing cutaneous dorsal finger defects based on the amount of available underlying tissue and location of the defect on the finger. RESULTS: In the authors' opinion, for smaller defects between and including the metacarpophalangeal joint extending to the proximal interphalangeal joint, a transposition flap or unilateral advancement flap is preferable. For proximal finger defects that are wider, a unilateral rotation flap is appropriate. A Burow full-thickness skin graft can be used for any proximal defect with underlying soft tissue present. For defects with underlying bone or tendon present, a reverse cross-finger interpolation flap can be utilized. CONCLUSIONS: The unilateral advancement flap, unilateral rotation flap, transposition flap, full-thickness skin grafts, or the reverse cross-finger interpolation flap can be used to reconstruct the majority of cutaneous dorsal finger defects.

BACKGROUND: The increased use of Mohs micrographic surgery (MMS) to treat melanoma has been accompanied by wide variations in practice patterns and a lack of best practice guidelines. OBJECTIVE: The present study was a nationwide cross-sectional survey of Mohs surgeons to elucidate commonalities and variations in their use of MMS to treat melanoma. MATERIALS AND METHODS: A cross-sectional analysis was performed using survey responses of Mohs surgeons with membership in the American College of Mohs Surgery. RESULTS: A total of 210/513 (40.9%) participants used MMS to treat melanoma of any subtype and 123/210 (58.6%) participants within this group treated invasive T1 melanoma (AJCC Eighth Edition) with MMS. A total of 172/210 (81.9%) participants debulked melanoma in situ (MIS). Average margin size of the first Mohs stage for MIS was 4.96 ± 1.74 mm. A total of 149/210 (71.0%) participants used immunohistochemical stains, with 145/149 (97.3%) using melanoma antigen recognized by T-cells 1 (MART-1) in 96.5% of melanoma cases treated with MMS. CONCLUSION: Over half of surveyed Mohs surgeons treating melanoma with MMS are treating early invasive melanoma with MMS. Most Mohs surgeons treating melanoma with MMS debulk MIS and virtually all use MART-1 when excising invasive melanoma with MMS.

BACKGROUND: Keratoacanthomas (KAs) are neoplasms of squamous epithelium which exhibit rapid growth and are often difficult to distinguish clinically from squamous cell carcinoma. Excision is the most common treatment, but in refractory cases or for KAs in cosmetically sensitive areas, nonoperative modalities may be better suited. OBJECTIVE: To compare efficacies of topical and intralesional therapies for the treatment of KAs. METHODS: A systematic literature review was performed using Medline, Ovid, and Embase. Studies looking at the efficacy of topical or intralesional treatments for KAs were included. To compare efficacy, 2-tailed t-tests were performed, with P < .05 considered statistically significant. RESULTS: Forty-one studies were identified across 5 modalities. Both topical and intralesional treatments had high KA eradication rates (92%-100%). Intralesional 5-fluorouracil led to faster KA healing times when compared to intralesional methotrexate (3.7 vs 4.6 weeks, P = .017). Similarly, topical 5-fluorouracil led to faster time to heal than topical imiquimod (3.8 vs 7.6 weeks with imiquimod, P < .0001). CONCLUSION: For nonoperative treatment of KAs, strong evidence currently exists for both topical and intralesional therapies. Decisions on which modality to use should be made on a case-by-case basis.

RESUMO
Keratoacanthomas are rapidly growing neoplasms of squamous epithelium. Despite their benign nature, they are often difficult to distinguish from squamous cell carcinoma and require excision. In cases in which excision is not successful or not desired, intralesional treatments may be considered. However, limited research exists on individual therapeutic efficacy. We present a 68-year-old man who developed multiple eruptive keratoacanthomas around the wound edge of a previous keratoacanthoma excision. Considering previous excisional failure, intralesional 5-fluorouracil was used as a treatment modality. Injections every 3-4 weeks over a course of 12 weeks induced clinical keratoacanthoma clearance with excellent cosmetic results. This case showcases that weekly intralesional 5-fluorouracil injections, as was the standard mode of treatment in previous case reports, may not be necessary. This less frequent injection strategy is more convenient for the patient and may lead to fewer treatments and less medication necessary. Although a case-by-case basis is needed for any alternative approach to keratoacanthoma treatment, this report is useful for the practicing clinician in showing that 5-fluorouracil may be efficacious in these difficult-to-treat patients.
