RESUMO
BACKGROUND: Recent increase in skin biopsies has been attributed to an epidemic of skin cancer. This may be avoidable, with potential savings. OBJECTIVE: To determine whether the increase in skin biopsies is attributable to increasing frequency of biopsies associated with histology lacking pathological cutaneous disease. Pathological cutaneous disease was defined as (1) a malignancy, precancerous lesion, or lesion of uncertain behavior; or (2) disease symptomatic or associated with adverse quality of life impact. PATIENTS AND METHODS: Retrospective cohort study, 2006 to 2013 of dermatology practice serving Florida and Ohio. Data were a consecutive sample of skin biopsies for diagnosis of dermatologic disease. RESULTS: A total of 267,706 biopsies by an average of 52 providers per month from January 06 to December 13 were analyzed. Number of biopsies per visit increased 2% per year (RR: 1.02, CI: 1.00-1.04). Likelihood of biopsy associated with histology indicative of nonpathological cutaneous disease did not increase over time (OR: 0.99, CI: 0.95-1.03, p = .6302). CONCLUSION: Rates of biopsies associated with nonpathological cutaneous disease is not increasing. Overall biopsy rates per visit have gradually increased; this seems attributable to greater rates of detection of pathological dermatologic disease.

BACKGROUND: Randomized controlled trials are the gold standard for comparing safety and effectiveness of surgical interventions. Reporting guidelines are available for conveying the results of such trials. OBJECTIVE: To assess adherence to standard reporting guidelines among randomized controlled trials in dermatologic surgery. MATERIALS AND METHODS: Systematic review. Data source was randomized controlled trials in the journal Dermatologic Surgery, per PubMed search, 1995 to 2014. Studies were appraised for the number of the 37 CONSORT 2010 Checklist criteria reported in each. Analysis included comparison of reporting across 4 consecutive periods. RESULTS: Three hundred sixty-three studies were eligible. The mean number of items reported per study increased monotonically from 14.5 in 1995 to 1999 to 16.2 in 2002 to 2004, 17.7 in 2005 to 2009, and 18.0 in 2010 to 2014 (p < .0001). A limitation was that study procedures may have been performed without being reported. CONCLUSION: Completeness of reporting in randomized controlled trials in dermatologic surgery has improved significantly during the preceding 2 decades. Some elements are still reported at lower rates.

Acne scarring results from a common inflammatory condition present in many people. These scars can have an impact on quality of life by influencing self-esteem and social acceptance. Current acne scarring treatments, such as chemical peels and laser treatments, often have limited success due to their time-consuming nature and the variability of acne scar types. The subcision technique has shown promise for the treatment of rolling acne scars. There are few studies to date that examine the effects of multiple subcision treatments on rolling acne scars. We evaluated whether the use of multiple subcision treatments improved the appearance of rolling acne scars compared to no treatment. Five patients with rolling acne scars on both sides of their face who met inclusion and exclusion criteria were enrolled in the study. One side of the face was randomized to receive treatment, while the contralateral side of the face received no treatment. Subjects underwent five sequential subcision treatments, spaced 4 weeks apart, with two follow-up visits at weeks 20 and 36 from the 1st treatment. Photographs were taken before and after the initial treatment visit and at each subsequent visit. Acne scar appearance was evaluated by the subject, a blinded live rater, and two double-blinded dermatologist raters. Evaluations of treatment outcomes involved overall acne scar appearance on a 5-point scale, acne scar improvement on a percentage scale, a modified quantitative global scarring grading system, and potential treatment side effects. There was a greater decrease in global scarring scores in the multiple subcision side compared to the control side. There was a greater difference in the average acne scar appearance scores between the Week 36 follow-up visit and baseline for the multiple subcision side compared to that of the control side. 50% of patients reported being more satisfied with the treatment side compared to the control side in regard to overall improvement. The study results suggest that multiple subcision treatments may improve the appearance of rolling acne scars compared to no treatment.

Therapeutic options for acne scars include subcision and suction with microdermabrasion, but these treatment modalities have not been studied in conjunction. To compare effectiveness of subcision alone versus subcision with suction for the treatment of facial acne scars. Randomized, split-faced, evaluator-blinded control trial. Participants underwent one subcision treatment on both sides of the face followed by 10 sessions of suction to one side. Photographs at baseline, 1-month, and 4-months were assessed. Primary outcome measures were the validated Acne Scar Severity Scale (ASSS) (0 = no acne scarring, 4 = severe), Acne Scar Improvement Grading Scale (ASIGS) (-100 to 100%), and modified Quantitative Global Scarring Grades (QGSG) (point-based questionnaire instrument), as well as subject preference. Twenty-eight treatment areas and 154 treatments were analyzed. Dermatologist raters found no differences between subcision alone and subcision-suction at 1-month or 4-months. Mean subject-assessed percent improvement for subcision-suction was higher than that for subcision alone at 1-month (37% versus 24%, p = 0.04) but not at 4-months (p = 0.37). Subjects preferred combination therapy to monotherapy at 1-month (50% vs. 21%) and 4-months (43% vs. 21%). While blinded raters did not detect significant differences, subjects perceived combination treatment as working more quickly than monotherapy, and preferred combination treatment at all time points.Clinical trial registration NCT01696513 on Clinicaltrials.gov.

Surgical site infections (SSIs) contribute to morbidity and are costly to the healthcare system. To identify factors associated with SSIs. Case-control study analyzing the Nationwide Readmission Database (NRD). We identified 45,445 SSIs. Infection rates were higher in those who were obese (BMI ≥ 30) (OR: 1.39, 95% CI 1.28-1.51), tobacco users (OR: 1.08, 95% CI 1.02-1.15), diagnosed with diabetes (OR: 1.16, 95% CI 1.10-1.22), with Elixhauser Comorbidity Index ≥ 2 (OR: 1.14, 95% CI 1.09-1.20), admitted to hospital for 4-6 days (OR: 1.35, 95% CI 1.29-1.42), in medium-size hospital (OR: 1.15, 95% CI 1.05-1.26), or large-size hospital (OR: 1.43, 95% CI 1.31-1.56). In contrast, patients who were 60-79 years old (OR: 0.78, 95% CI 0.73-0.84), 80 years or older (OR: 0.66, 95% CI 0.59-0.73), female (OR: 0.95, 95% CI 0.91-0.99), underweight (BMI < 18.5) (OR: 0.14, 95% CI 0.03-0.59), in a non-metropolitan hospital (OR: 0.83, 95% CI 0.75-0.91), self-pay (OR: 0.82, 95% CI 0.74-0.91), or covered by Medicare (OR: 0.86, 95% CI 0.80-0.91) had lower odds. Initial data entry to NRD is susceptible to human error. Patients who are obese, use tobacco, have multiple comorbidities, and have long hospital stays in medium-to-large-size hospitals are at risk of SSIs. Conversely, odds of SSIs are lower in females, age ≥ 60, BMI < 18.5, self-pay or Medicare (versus private insurance), or at smaller hospitals. Understanding factors associated with SSIs may help surgeons anticipate complications.

Cosmetic and laser procedures are increasingly popular among patients and are skills in which dermatologists are regarded as well trained. Most dermatology residents intend to incorporate cosmetic procedures into their practice and prefer to learn such procedures during residency through direct patient care. However, there are notable challenges in optimizing how residents are trained in cosmetic and laser dermatology. To address these barriers and elevate the practice of cosmetic dermatology in academic medicine, the Association of Academic Cosmetic Dermatology (AACD) was founded in 2021 as the lead professional society for dermatologists who direct the education of resident trainees in cosmetic and laser dermatology. The AACD, a group of board-certified dermatologists who teach cosmetic and laser dermatology to residents, aims to improve cosmetic dermatology education through collaboration, research, and advocacy.

Cosmetic dermatology is a key subspecialty of academic dermatology. As such, academic centers are expected to demonstrate excellence in the teaching of cosmetic dermatology skills to trainees, the clinical delivery of cosmetic dermatology services to patients, and the performance of clinical research that advances knowledge and uncovers new therapies in cosmetic dermatology. The Association of Academic Cosmetic Dermatology (AACD), a newly formed medical professional society, includes as its principal aims the support of all of these areas. AACD is comprised of group of board-certified dermatologists who teach cosmetic and laser dermatology at US dermatology residency programs. An expert panel constituted by the AACD recently convened a workshop to review gaps pertaining to academic cosmetic dermatology. This panel considered needs and potential corrective initiatives in three domains: resident education, patient experience, and clinical research. The work of the panel was used to develop a roadmap, which was adopted by consensus, and which will serve to guide the AACD moving forward.

Dermatofibrosarcoma protuberans (DFSP) is a cutaneous sarcoma that has remained a challenge for oncologic and reconstructive surgeons due to a high rate of local recurrence. The objective of this study is to investigate the oncologic and reconstructive benefits of employing a multidisciplinary two-step approach to the treatment of DFSP. A retrospective review was conducted using a prospectively collected database of all patients who underwent resection and reconstruction of large DFSPs by a multidisciplinary team, including a Mohs micrographic surgeon, surgical oncologist, dermatopathologist, and plastic and reconstructive surgeon, at one academic institution from 1998-2018. Each patient underwent Mohs micrographic surgery for peripheral margin clearance (Step 1) followed by wide local excision (WLE) of the deep margin by surgical oncology and immediate reconstruction by plastic surgery (Step 2). 57 patients met inclusion criteria. Average defect size after WLE (Step 2): 87.3 cm2 (range 8.5-1073.5 cm2). Mean follow-up time was 37 months (range 0-138 months). There were no cases of recurrence. A two-step multidisciplinary surgical treatment approach for DFSP minimizes risk of recurrence, decreases patient discomfort, and allows immediate reconstruction after deep margin clearance.

OBJECTIVE: To determine the number of Mohs micrographic surgery (MMS) stages per tumor taken by early- to mid-career Mohs surgeons and to assess other factors affecting number of stages. METHODS: Statistical analysis of MMS logs of 20 representative early- to mid-career surgeons. RESULTS: There was no difference in stages when surgeons were divided into two categories based on whether they had more than 500 cases per year or more than 5 years of experience. Similarly, when surgeons were categorized according to geographic location, there was no difference in number of stages. Anatomic location was associated with the number of stages (analysis of variance, p<.001), with the greatest number of stages for nose (2.01) and ear (2.06) lesions and the fewest for neck (1.47), back and shoulder (1.47), and lower extremity (1.33) lesions. Basal cell carcinomas required 1.92 stages (median 2.00), compared with 1.66 (median 1.00) for squamous cell carcinoma (p<.001). CONCLUSIONS: Early- and mid-career Mohs surgeons appear to remove tumors with similar numbers of stages regardless of their experience, case volume, or geographic location. Number of stages varies with anatomic location and tumor type. The authors have indicated no significant interest with commercial supporters.

OBJECTIVES: To assess the strength of 2.0 barbed polypropylene suture, and, specifically, to determine the load required to break this suture, and to compare this with the strength of nonbarbed polypropylene suture. DESIGN: Rater-blinded, controlled trial. The individual responsible for setting up the experimental conditions was not blinded. SETTING: Biomechanics laboratory in an academic medical center. MATERIALS: This study did not include human subjects. Materials used included six 2.0 barbed polypropylene sutures and 3 each of 2.0, 3.0, 4.0, and 5.0 nonbarbed polypropylene sutures. Each suture was randomly selected from a different batch or box of similar sutures. INTERVENTION: Each suture was strung between 2 (top and bottom) cylinders and tied with a surgeon's knot. A tensile testing device was used to apply increasing force until the suture broke. Data were acquired through an analog-to-digital board on an IBM-compatible computer using commercially available software. MAIN OUTCOME MEASURES: Ultimate strength, stiffness, and elongation before suture rupture. RESULTS: Strength of the barbed sutures (mean [SD] ultimate strength, 39.5 [9.0] N) was intermediate between that of 2.0 (55.0 N) and 3.0 (36.4 N) nonbarbed sutures and was not significantly different from that of 3.0 nonbarbed sutures (P = .5). Barbed 2.0 polypropylene sutures differed significantly (P < .001) from each of the other types of nonbarbed sutures on measures of stiffness and elongation. Elongation of barbed sutures was closest to that of 3.0 nonbarbed sutures (P = .002). Stiffness of the barbed sutures (mean [SD], 4.7 [0.7] N/mm) was markedly in excess of that of any of the other suture types (P < .001). CONCLUSIONS: Barbed 2.0 polypropylene sutures seem to be at least as strong as 3.0 nonbarbed polypropylene sutures. As such, barbed sutures are significantly stronger than their rated strength, which has been stated as comparable to 4.0 nonbarbed sutures. This has implications for the long-term in vivo safety of barbed sutures.

BACKGROUND: Injectable calcium hydroxylapatite is a soft-tissue augmentation material that is used off-label for facial augmentation, including repletion of depressed nasolabial folds. OBJECTIVE: We sought to assess the safety of calcium hydroxylapatite injection for correction of nasolabial fold depressions. Specifically, we sought to obtain a quantitative assessment of injection-related adverse events using a reproducible placement technique with long-term follow-up. METHODS: We conducted an open-label, single-center prospective study using reproducible technique with 1- to 1.5-year follow-up. All patients were treated with infraorbital nerve blocks. Then, parallel linear threading technique using 27-gauge/1.25-in needles was used to place 1 to 2 mL of injectant at the dermal subcutaneous junction into each pair of depressed folds. A triangular array of injectant was deposited under the melonasal junction. At follow-up at 2 to 3 weeks and at 1 to 1.5 years, respectively, patients were asked to report and characterize injection-related redness, swelling, bruising, nodule or granuloma formation, asymmetric correction, textural change, hypersensitivity reactions, degree of correction remaining, and overall satisfaction. In addition, patients who had received other injectable soft-tissue materials were asked to compare these with calcium hydroxylapatite in terms of risk profile and longevity of effect. RESULTS: In all, 22 patients were treated and complete follow-up data were obtained from 18. Of the 18 patients, all reported at least mild postinjection redness and swelling, which abated within 1 to 5 days. Bruising was reported by fewer than half, and resolved within 4 to 10 days. Palpable but not visible nodules were reported by 2 of 18 patients; these resolved within 3 months of injection. Asymmetric correction, textural change, granulomas, and hypersensitivity reactions were not reported. In all, 14 of 18 patients reported that cosmetically significant correction lasted longer than 1 year. Two thirds of injected patients who had received other fillers for nasolabial fold correction preferred calcium hydroxylapatite, with the primary reason being increased longevity of effect. LIMITATIONS: There was a lack of objective outcomes measures. CONCLUSIONS: When a consistent, defined injection technique is used, injectable calcium hydroxylapatite appears to be a well-tolerated soft-tissue augmentation material for correction of nasolabial fold depressions. A long duration of effect may make this material particularly desirable for some patients.

In dermatology, botulinum toxin is now most often used to reduce dynamic facial creases and treat primary focal hyperhidrosis. The exemplary safety record of this medication is such that after nearly 2 decades, it is not known to have any long-term adverse events. Transient adverse events, such as mild injection pain, are typically minor and spontaneously remitting. Headache, nausea and flu-like symptoms, lid and brow ptosis after upper face injection, lower face asymmetry after perioral injection, and fine motor impairment after palmar injection are uncommon to rare. Understanding of anatomic landmarks and site-specific precautions can further mitigate the incidence of unwanted effects. Patients who do experience uncommon, transient effects can be reassured that these are not dangerous and will resolve completely without intervention.

BACKGROUND: A preponderance of evidence now indicates that storage of reconstituted botulinum toxin solution for longer than the 4 hours recommended by the manufacturer does not result in loss of effectiveness. OBJECTIVE: Then purpose of this study was to assess whether serial re-extraction of reconstituted botulinum toxin solution from vials undergoing prolonged storage is associated with increased risk of microbial contamination. METHODS: Consecutive 100-U vials of botulinun A exotoxin were reconstituted with 2.5 mL each of normal saline with preservative (benzyl alcohol). Within 1 week after reconstitution, each vial was used to treat 1 to 3 patients, for a total of 60 to 80 U used. Thereafter, each vial was stored in a plastic kidney basin in an unlocked, multiuse medication refrigerator. Two weeks later, a randomly assigned nurse removed the vial from the refrigerator and withdrew and discarded 0.1 mL (5 U) using the same technique used for therapeutic extractions. Iterations of this withdrawal and discarding procedure were continued until a 0.1-mL aliquot could not be withdrawn without prying off the metal cover. Once this threshold was reached, the vial was sent to the microbiology laboratory for sterility testing using a thioglycolate broth. RESULTS: In all, 127 vials were handled per protocol. On average (mean), vials underwent 4.5 access procedures, including 1.6 therapeutic extractions for a total of 76 U removed during a period of 7 weeks. Sterility analysis with thioglycolate broth indicated no evidence of contamination. LIMITATIONS: Preservative-containing saline was used for reconstitution. CONCLUSION: Routine refrigerator storage of medication vials containing reconstituted botulinum toxin does not result in microbial contamination of the contents even after serial re-extraction of solution from these vials, and after handling of such vials by multiple personnel. Storage and subsequent reuse of botulinum toxin appears safe for at least 7 weeks after reconstitution.
