Background and objective Actinic keratoses (AKs) have been described with varying color and morphology; however, no reports have demonstrated associations between color, vasculature, and inflammation. In this retrospective study, we analyze the clinical, dermoscopic, and histopathologic features of AKs to elucidate this relationship. Methods A retrospective search for patients diagnosed with AK between January 2018 and October 2019 was performed. Clinical and dermoscopic photographs and pathology slides for all included subjects were reviewed. Results Forty-nine images and histopathology slides were analyzed. Dermoscopy of white AKs demonstrated scale and absence of erythema with corresponding absence of inflammation on histopathology. Dermoscopy of brown AKs revealed pseudonetwork, absent scale, and a variable vessel pattern with pigment incontinence and absence of inflammation on histopathology. Red AKs had a distinct polymorphous vessel pattern and presence of erythema on dermoscopy. On histopathology, about half of samples showed increased vascularity and variable inflammation. Pink AK dermoscopy revealed a presence of erythema with corresponding presence of inflammation on histopathology. Conclusion This report adds to our understanding of AKs and confirms that, in general, the pinker or redder the AK, the more prominent the inflammatory infiltrate and vasculature, respectively. Dermatologists should continue to use their diagnostic skills to successfully diagnose and triage AKs.

Medications may be specially prepared, or "compounded," to meet the needs of patients who cannot use standard formulation. The United States Pharmacopeia (USP) Convention is a private, nongovernmental organization which independently develops guidelines for pharmaceuticals. The purpose of this survey study is to better understand the extent to which state boards of pharmacy currently incorporate relevant USP guidelines into their compounding regulations.Executive directors or other administrative representatives of each state board of pharmacy were invited to respond to six open-ended questions. Their free text responses were analyzed by two reviewers (KR, SI) using qualitative research techniques. The response rate was 71% (36/51). Almost all (35/36, 97%) indicated that they implement USP compounding standards at least in part. Eighteen boards (18/28, 64%) reported that 'some, but not all standards' are enforced, most commonly 795 and 797 , but not 800 (9/28, 32%). Ten (10/28, 36%) indicated that 'all' USP compounding standards are enforced. Eighteen (18/21, 86%) only implement finalized USP standards, whereas three consider newly proposed chapters (3/21, 14%). Over half (22/36, 61%) employ a committee or similar process to select standards.Almost all responding state boards of pharmacy incorporate finalized USP compounding standards into their regulations, usually via a formal rulemaking process, with boards commonly implementing some standards but not all. Chapters 795 and 797 are implemented more commonly than 800 . Since Congress passed the Drug Quality and Security Act (DQSA), pharmacy boards are becoming increasingly observant of USP compounding standards.

Stromal vascular fraction (SVF), derived enzymatically or mechanically from adipose tissue, contains a heterogenous population of cells and stroma, including multipotent stem cells. The regenerative capacity of SVF may potentially be adapted for a broad range of clinical applications, including the healing of acute cutaneous wounds. To evaluate the available literature on the efficacy and safety of autologous adipose-derived stromal vascular fraction (SVF) for the treatment of acute cutaneous wounds in humans. A systematic review of the literature utilizing MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials was performed to identify published clinical trials of autologous adipose-derived SVF or similar ADSC-containing derivatives for patients with acute cutaneous wounds. This was supplemented by searches for ongoing clinical trials through ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform. 872 records were initially retrieved. Application of inclusion and exclusion criteria yielded 10 relevant studies: two completed non-randomized controlled trials and eight ongoing clinical trials. Both completed studies reported a statistically significant benefit in percentage re-epithelialization and time to healing for the SVF treatment arms. Safety information for SVF was not provided. Ongoing clinical trials were assessing outcomes such as safety, patient and observer reported scar appearance, wound healing rate, and wound epithelization. In the context of substantial limitations in the quantity and quality of available evidence, the existing literature suggests that SVF may be a useful treatment for acute cutaneous wounds in humans. More clinical trials with improved outcome measures and safety assessment are needed.

Nonscarring alopecia, including androgenetic alopecia and alopecia areata, are common and can negatively impact quality of life. Recent clinical studies have investigated autologous, adipose-derived stromal vascular fraction (SVF) as a potentially beneficial treatment option. To assess the available evidence on the utility and safety of SVF for nonscarring alopecia. A systematic review of the literature was performed using MEDLINE (PubMed), Embase, and CENTRAL from inception to November 2020. Included articles were prospective, observational or interventional studies of SVF for nonscarring alopecia in humans. Six studies of 188 patients were identified, including three randomized controlled trials. There were no reported severe adverse events. All studies found improved hair density with SVF compared to control or pre-treatment baseline. One study reported that improvement in hair density varied based on time for follow-up, severity of hair loss, and concentration of adipose-derived stem cells (ADSCs) within the SVF. Two studies reported an increase in hair diameter from baseline, and two studies reported an improvement in hair pull test outcomes. SVF may be safe and effective for nonscarring alopecia in the appropriate patients. Hair loss severity, method of SVF preparation and frequency of treatment, and adjunctive therapies may be important considerations for treatment success. Additional studies evaluating appropriate patient selection and treatment methods are needed.

Introduction To compare glycemic variability (GV) and time in range (TIR) in Chinese patients with type 2 diabetes (T2D) initiated on once-daily bedtime insulin glargine 300U/ml (Gla-300) versus neutral protamine Hagedorn (NPH) insulin using continuous glucose monitoring (CGM). Methods This was a 24-week, open-label exploratory study with 1:1 randomization comparing patient-adjusted titration of Gla-300 (n = 23) versus NPH (n = 23) at bedtime in insulin-naïve T2D patients on maximum oral glucose-lowering drugs. The starting dose was 0.2 U/kg/day and with self-titration of one unit per week to achieve a target fasting glucose of 4.4–6 mmol/l, without hypoglycemia. Participants had masked CGM at baseline, weeks 11 and 24. The primary outcome was between-treatment differences in CGM glucose standard deviation (SD) at week 24. Results HbA1c at week 24 were similar, with 21% of Gla-300 versus 4% of NPH-treated patients achieving HbA1c

The CAPER Registry is a voluntary, national safety reporting program that gathers patients' adverse events encountered during dermatologic procedures. This registry is intended as an aid for practitioners, patients, industry, and government regulators, and aims to facilitate safety monitoring for the specialty by identifying resource, process, education, and other systemic gaps associated with adverse events, as well as any potential risk factors for adverse events. CAPER will provide new or corroborating information to help dermatologists improve clinical practices, improve safety and effectiveness, and treat and prevent adverse events. The data generated will also help industry partners and regulatory bodies prevent adverse events from going unnoticed.

Background Previous studies suggest gliclazide is metabolised primarily by CYP2C19 rather than CYP2C9, unlike other sulphonylureas. CYP2C19 *2 and *3 polymorphisms are more common in Asians. Methods We investigated the effect of CYP2C19 polymorphisms on gliclazide pharmacokinetics in 15 healthy male Chinese subjects after a single 80mg oral dose. Results In CYP2C19 poor metabolisers (*2/*2, n=4), plasma area-under-the-curve was higher by nearly two-fold compared with intermediate metabolisers (*2 and *3 heterozygotes, n=7) and extensive metabolisers (*1/*1, n=4) (p

Injection of platelet concentrates for the treatment of aging skin has gained popularity. The objective was to systematically assess the evidence regarding the safety and effectiveness of platelet-rich plasma (PRP) for reducing the visible signs of aging. Cochrane Library, MEDLINE (PubMed), EMBASE, and Scopus were searched from inception to March 2019 for prospective trials and case series assessing PRP for skin aging in 10 or more patients. Twenty-four studies, including 8 randomized controlled trials (RCTs), representing 480 total patients receiving PRP, were included. Based on physician global assessment, injection PRP monotherapy was shown to at least temporarily induce modest improvement in facial skin appearance, texture, and lines. Periorbital fine lines and pigmentation may also benefit. Adjuvant PRP accelerated healing after fractional laser resurfacing. Although the degree of improvement was typically less than 50%, patients generally reported high satisfaction. It was limited by heterogeneity in PRP preparation and administration, and lack of standardization in outcome measures. PRP injections are safe and may be modestly beneficial for aging skin. The evidence is most convincing for improvement of facial skin texture. The persistence of these effects is not known. More high-quality trials with sufficient follow-up are needed to optimize treatment regimens.

Postinflammatory hyperpigmentation (PIH) is a disorder of pigmentation that is a common presenting complaint, especially in individuals with skin of color. It is associated with a significant psychological burden and decrement of quality of life. Management options include photoprotection, topical lightening agents, and lasers and energy devices. Clinical trials of melasma report a diversity of outcomes, which often impedes synthesis of results across trials, or comparison of results associated with different treatment modalities. This protocol describes the design of a consensus process that would culminate in the development of a core set of outcomes to be assessed in all clinical trials for PIH. A long list of candidate outcomes will be developed through a systematic review, combined with semi-structured interviews with various stakeholders, including patients, scientists, regulators, and health care professionals. This long list of outcomes will be reviewed and refined by a steering committee. Then two rounds of Delphi surveys of patient and physician groups, respectively, will be used to cull the list, with provisional inclusion of those items deemed “important” by 70% of the respondents. A consensus meeting will be held virtually or in person to vote on these items, and also to consider any changes necessary before acceptance of a final core outcome set. Development of a core outcome set for PIH is expected to improve and standardize outcomes reporting in current and future clinical trials. This, in turn, may facilitate aggregation of research results and permit comparison of outcomes across multiple studies.

Background. According to the Center for Disease Control and Prevention (CDC), half of the 20 million new sexually transmitted infections (STIs) occur annually in youth aged 15 to 24. It is critical for dermatologists to be able to provide young patients with accessible education about how to identify, prevent, and treat these conditions. Our pilot study sought to assess the impact of a live presentation about STIs in high school students and to evaluate students’ baseline and acquired knowledge about common STIs using a before and after survey. Methods. This survey study was conducted as part of the health education curriculum at a suburban high school. An interactive scenario-based presentation about STIs was given to participants. Identical, deidentified preintervention and postintervention surveys were completed by subjects to assess their baseline and acquired knowledge of STIs. Each question was worth 1 point, for a total of 8 points. Results. 74 high school students were surveyed. Overall, there was a mean improvement of 1.85 points in the posttest score in comparison to pretest score with a standard deviation of 1.58 ( p < 0.0001 ). Among all participants, the mean pretest score was 1.07 (SD = 0.75) and the mean posttest score was 2.92 (SD = 1.59). Conclusions. This study demonstrated that many young adults are unaware of the common types of STIs, symptoms, and potential complications. While our scenario-based presentation was effective at providing understandable content to help improve students’ knowledge regarding STIs, additional educational resources in varied formats could likely further these gains.

Background The type of cosmetic dermatologic procedures patients' desire may be influenced by demographic factors. Objective To better understand the type of cosmetic procedures requested by patients of different age, gender, education, race, and geographic location. To understand the most common motivations of patients who requested particular types of treatments. Materials and methods Multicenter data from the Cosmetic Motivation Database were analyzed. Bivariable analyses and linear regressions were undertaken to determine whether patient demographic features were associated with particular procedures of interest. Results Patients younger than 45 years were more interested in acne scar treatment, laser hair removal, liposuction, and tattoo removal. Older patients were more likely to want soft-tissue fillers and wrinkles and jowls tightening treatment. Non-White patients were more likely to be interested in laser hair removal, liposuction, cellulite treatment, and tattoo removal. Types of procedures desired varied by the geographic region but not by the educational level. Different motivations drove patients who wanted different types of treatments. Conclusion Different types of patients demand different types of cosmetic treatments, and the motivations of patients who ask for particular procedures also differ. Better understanding of patient preferences may help physicians allocate resources and meet patient needs.

Patients presenting for cosmetic dermatology procedures are often interested in lifestyle enhancement rather than treatment of an inflammatory or neoplastic disease or condition. In addition to good clinical outcomes, they may also particularly value the quality of the patient experience in the dermatology office. A list of beneficial practices that may improve patient experience was generated by interviewing staff members from several US practices, including clinic administrators, nurses, nurse managers, medical assistants, physician assistants, patient care coordinators, and dermatologists. Each was asked ten open-ended questions. The list of beneficial practices thereby obtained was ordered based on the number of participants who recommended each practice. Practices were further categorized into four categories: clinician improvement, administrative improvement, clinic improvement, and team improvement. For clinics providing cosmetic dermatology services, certain well-accepted beneficial practices may improve patient experience.

Importance Although various treatments have been found in clinical trials to be effective in treating actinic keratosis (AK), researchers often report different outcomes. Heterogeneous outcome reporting precludes the comparison of results across studies and impedes the synthesis of treatment effectiveness in systematic reviews. Objective To establish an international core outcome set for all clinical studies on AK treatment using systematic literature review and a Delphi consensus process. Evidence Review Survey study with a formal consensus process. The keywordsactinic keratosisandtreatmentwere searched in PubMed, Embase, CINAHL, and the Cochrane Library to identify English-language studies investigating AK treatments published between January 1, 1980, and July 13, 2015. Physician and patient stakeholders were nominated to participate in Delphi surveys by the Measurement of Priority Outcome Variables in Dermatologic Surgery Steering Committee members. All participants from the first round were invited to participate in the second round. Outcomes reported in randomized controlled clinical trials on AK treatment were rated via web-based e-Delphi consensus surveys. Stakeholders were asked to assess the relative importance of each outcome in 2 Delphi survey rounds. Outcomes were provisionally included, pending the final consensus conference, if at least 70% of patient or physician stakeholders rated the outcome as critically important in 1 or both Delphi rounds and the outcome received a mean score of 7.5 from either stakeholder group. Data analysis was performed from November 5, 2018, to February 27, 2019. Findings A total of 516 outcomes were identified by reviewing the literature and surveying key stakeholder groups. After deduplication and combination of similar outcomes, 137 of the 516 outcomes were included in the Delphi surveys. Twenty-one physicians and 12 patients participated in round 1 of the eDelphi survey, with 17 physicians (81%) retained and 12 patients (100%) retained in round 2. Of the 137 candidate outcomes, 9 met a priori Delphi consensus criteria, and 6 were included in the final outcomes set after a consensus meeting: complete clearance of AKs, percentage of AKs cleared, severity of adverse events, patient perspective on effectiveness, patient-reported future treatment preference, and recurrence rate. It was recommended that treatment response be assessed at 2 to 4 months and recurrence at 6 to 12 months, with the AK rate of progression to cutaneous squamous cell carcinoma reported whenever long-term follow-up was possible. Conclusions and Relevance Consensus was reached regarding a core outcome set for AK trials. Further research may help determine the specific outcome measures used to assess each of these outcomes.

Background Noninvasive fat removal is preferred because of decreased downtime and lower perceived risk. It is important to seek new noninvasive fat removal treatments that are both safe and efficacious. Objective To assess the extent to which carboxytherapy, which is the insufflation of carbon dioxide gas into subcutaneous fat, results in reduction of fat volume. Methods In this randomized, sham-controlled, split-body study, adults (body mass index, 22-29 kg/m2) were randomized to receive 5 weekly infusions of 1000 cm3 of CO2 to 1 side of the abdomen, and 5 sham treatments to the contralateral side. The primary outcome measures were ultrasound measurement of fat layer thickness and total circumference before and after treatment. Results A total of 16 participants completed the study. Ultrasound measurement indicated less fat volume on the side treated with carboxytherapy 1 week after the last treatment (P = .011), but the lower fat volume was not maintained at 28 weeks. Total circumference decreased nominally but not significantly at week 5 compared with baseline (P = .0697). Participant body weights did not change over the entire course of the study (P = 1.00). Limitations Limitations included modest sample size and some sources of error in the measurement of circumference and fat layer. Conclusion Carboxytherapy provides a transient decrease in subcutaneous fat that may not persist. Treatment is well tolerated.

Background and objective Noninvasive fat reduction appears effective, but there are various methods for quantifying changes. The objective of this review is to assess comparative utility measures of subcutaneous fat. Study design/materials and methods Articles describing noninvasive fat reduction were searched using MEDLINE, EMBASE, CINAHL and Scopus electronic databases on two dates (January 28, 2014 and February 16, 2016). Titles of studies and abstracts were screened for eligibility. Manual review was performed by two investigators to detect those that: (1) included original data; (2) were randomized controlled trials, or prospective or retrospective cohort studies; (3) quantified fat outcomes; and (4) enrolled at least 10 subjects. Results Of 1,057 retrieved articles, 36 met criteria. Most reported four or more measurement techniques. Circumference measurements were most commonly cited. Other objective techniques, like caliper thickness, ultrasound, magnetic resonance imaging (MRI), and three-dimensional (3D) photography, were also used. Common subjective methods were evaluation of standardized photographs by blinded raters and patient satisfaction surveys. Conclusions For quantifying noninvasive fat reduction, all available methods had significant limitations: photographic comparisons were subjective; circumference or caliper measurements were confounded; ultrasound was operator dependent; MRI was expensive; computed models and simulations were in early development. As new technologies are developed, the need for reliable, accurate and practical measures of subcutaneous fat will increase. Lasers Surg. Med. 50:96-110, 2018. © 2017 Wiley Periodicals, Inc.

Background Photographs are an essential tool for the documentation and sharing of findings in dermatologic surgery, and various camera types are available. Objective To evaluate the currently available camera types in view of the special functional needs of procedural dermatologists. Methods Mobile phone, point and shoot, digital single-lens reflex (DSLR), digital medium format, and 3-dimensional cameras were compared in terms of their usefulness for dermatologic surgeons. For each camera type, the image quality, as well as the other practical benefits and limitations, were evaluated with reference to a set of ideal camera characteristics. Based on these assessments, recommendations were made regarding the specific clinical circumstances in which each camera type would likely be most useful. Results Mobile photography may be adequate when ease of use, availability, and accessibility are prioritized. Point and shoot cameras and DSLR cameras provide sufficient resolution for a range of clinical circumstances, while providing the added benefit of portability. Digital medium format cameras offer the highest image quality, with accurate color rendition and greater color depth. Three-dimensional imaging may be optimal for the definition of skin contour. Conclusion The selection of an optimal camera depends on the context in which it will be used.

Objective Although dermatologists strive to provide patient education on sun protection and skin cancer, approximately 90% of Americans have limited health literacy skills. Little has been written about the means to best teach all levels of learners to recognize common benign and malignant skin lesions. Earlier work found that with advancing age, adults were less able to identify concerning lesions, thus underscoring the need for accessible education. Methods We showed subjects a brief video (7th grade level) about common cutaneous growths, reducing the risk of skin cancer, and the importance of early detection. Subjects were asked about their skin cancer history, educational format preference, and the perceived impact of the video. Comprehension of symptoms of skin cancer and the benefits of sunscreen use and the ability to identify a melanoma, nevus, angioma, and seborrheic keratosis were also assessed. Results Of the 156 subjects, mean age 52.7 years (range, 18-88 years), 31% had a history of skin cancer. A total of 98.7% found the video to be helpful; 92% preferred having a video as part of their teaching versus 9% who preferred written materials alone, 99% knew that a new or changing lesion could signal skin cancer, and 100% correctly answered that wearing sunscreen is protective. Subjects correctly identified lesions as melanoma (99%), benign mole (97%), angiomas (96%), and seborrheic keratosis (91%). There was a nominal trend toward higher scores in people who preferred video learning, had no history of skin cancer, and were older than 60 years of age. Conclusion In this study, we found that a brief, plain-language video was effective at conveying understandable content to help subjects learn to identify common cancerous and benign skin growths while also teaching them strategies to protect against skin cancer.

Sebaceous carcinoma (SC) is a potentially aggressive malignancy of periocular or extraocular skin. It arises sporadically or is associated with Muir–Torre syndrome (MTS). Here, we review three controversial clinical conundra related to the diagnosis and treatment of SC and offer evidence-based recommendations. First, following a diagnosis of SC, deciding which patients to screen for MTS can be challenging. The Mayo MTS Risk Score is a clinical score that incorporates the key cutaneous findings in MTS but relies heavily on personal and family history that may not be available at the time of SC diagnosis, especially in young patients. Young patients, who have extraocular SC and are suspected to have MTS though do not meet criteria by Mayo MTS Risk Score, should have their tumors tested using immunohistochemistry for mismatch repair proteins. Second, sentinel lymph node biopsy (SLNB) is used in periocular SC to evaluate nodal disease. Patient selection is critical for SLNB. Periocular SC stage ≥ T2c (by American Joint Commission on Cancer, 8th edition) may be considered for SLNB given positivity rates over fifteen percent in expert hands. Lastly, treatment of metastatic SC is an area of active investigation. When possible, tumor profiling may be used to select targeted agents. Future research into these three key questions is needed.

Sebaceous carcinoma usually occurs in adults older than 60 years, on the eyelid, head and neck, and trunk. In this Review, we present clinical care recommendations for sebaceous carcinoma, which were developed as a result of an expert panel evaluation of the findings of a systematic review. Key conclusions were drawn and recommendations made for diagnosis, first-line treatment, radiotherapy, and post-treatment care. For diagnosis, we concluded that deep biopsy is often required; furthermore, differential diagnoses that mimic the condition can be excluded with special histological stains. For treatment, the recommended first-line therapy is surgical removal, followed by margin assessment of the peripheral and deep tissue edges; conjunctival mapping biopsies can facilitate surgical planning. Radiotherapy can be considered for cases with nerve or lymph node involvement, and as the primary treatment in patients who are ineligible for surgery. Post-treatment clinical examination should occur every 6 months for at least 3 years. No specific systemic therapies for advanced disease can be recommended, but targeted therapies and immunotherapies are being developed.

Recent increase in skin biopsies has been attributed to an epidemic of skin cancer. This may be avoidable, with potential savings.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.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.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).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 Intracutaneous lidocaine is used for anesthesia in dermatologic surgery for skin cancer excision and repair with exceedingly low incidence of reported adverse events. Objective To measure (1) the quantity of lidocaine typically used for facial skin cancer excision and reconstruction; and (2) the frequency and character of associated adverse events. Methods Survey study of dermatologic surgeons with longitudinal reporting. Reported practice during 10 business days: (1) mean volume of 1% lidocaine per skin cancer excision; (2) maximum per excision; (3) mean per reconstruction; and (4) maximum per reconstruction. Results A total of 437 of 1,175 subjects contacted (37.2%) responded. Mean per excision was 3.44 mL (SD: 2.97), and reconstruction 11.70 mL (10.14). Maximum per excision was 6.54 mL (4.23), and reconstruction was 15.85 mL (10.39). No cases of lidocaine toxicity were reported, diagnosed, or treated. Incidence of adverse events possibly anesthesia related was >0.15%, with most (0.13%) being mild cases of dizziness, drowsiness, or lightheadedness from epinephrine tachycardia. Conclusion Toxicity associated with local anesthesia other than lidocaine was not studied. Volumes of lidocaine in skin cancer excision and repair are modest and within safe limits. Lidocaine toxicity is exceedingly rare to entirely absent. For comparable indications, lidocaine is safer than conscious sedation or general anesthesia.

Background The American Council of Graduate Medical Education, which oversees much of postgraduate medical education in the United States, has championed the concept of "milestones," standard levels of achievement keyed to particular time points, to assess trainee performance during residency. Objective To develop a milestones document for the American Society for Dermatologic Surgery (ASDS) Cosmetic Dermatologic Surgery (CDS) fellowship program. Methods An ad hoc milestone drafting committee was convened that included members of the ASDS Accreditation Work Group and program directors of ASDS-approved Cosmetic Dermatologic Surgery (CDC) fellowship training programs. Draft milestones were circulated through email in multiple rounds until consensus was achieved. Results Thirteen milestones were developed in the 6 Accreditation Council for Graduate Medical Education (ACGME) competency areas, with 8 of these being patient-care milestones. Additional instructions for milestone administration more specific to the CDS fellowship than general ACGME instructions were also approved. Implementation of semiannual milestones was scheduled for the fellowship class entering in July 2018. Conclusion Milestones are now available for CDS fellowship directors to implement in combination with other tools for fellow evaluation.

Background Although treatments to address cosmetic concerns are common, patients' self-reported motives for considering such procedures have not been systematically explored. Objective To develop a framework of categories to describe patients' self-reported motivations for undergoing minimally invasive cosmetic procedures. Methods Face-to-face, semistructured patient interviews were conducted with adult participants who had undergone or were considering minimally invasive cosmetic dermatologic procedures. A qualitative constant comparative approach was used to analyze interview transcripts, yielding themes and subthemes. Results A total of 30 interviews were completed. Most patient-reported motivations for cosmetic procedures could be subsumed under 8 general categories (themes): (1) mental and emotional health, (2) cosmetic appearance, (3) physical health, (4) work and/or school success, (5) social well-being, (6) cost and/or convenience, (7) procedural perceptions, and (8) timing of treatment. Many individual motivations in these categories were unrelated to desire for physical beauty. In particular, participants wanted to avoid being self-conscious, enhance confidence, reduce the time and expense required to conceal physical imperfections, and be perceived as capable at work. Limitations Only English-speaking patients in the United States were interviewed. Conclusion Patient-reported motivations for cosmetic procedures mostly pertained to physical and psychosocial well-being. Indeed, a desire for improved cosmetic appearance was only 1 of the 8 themes revealed through the patient interviews.

Non-invasive skin-tightening devices can induce thermal denaturation and skin shrinkage via externally applied radiofrequency emissions or high-frequency ultrasound. Therefore, the purpose of this study is to develop and test a method for measurement of skin reduction associated with application of such energy devices. Twenty-five healthy participants with mild to moderate skin laxity of the arms were enrolled. Pinpoint microtattoos were placed at each of the treatment sites to delineate two 6 × 12 cm rectangles per subject. A non-stretchable filament, tape and marking pen apparatus was used to measure the size of each rectangle before treatment and at follow-up visit by two blinded investigators. After randomization, one side received a single pass with a radiofrequency device (6.78 MHz), while the contralateral side received multiple passes. Participants underwent two treatment sessions to each side 2 weeks apart, and returned for follow-up 4 weeks after the second treatment. Length and area measurement were analyzed to assess precision and accuracy of measurements and to compare efficacy of treatment between pre- and post-treatment. Concordance correlation coefficients (CCC) demonstrated substantial inter-investigator reliability and precision in length measurements (CCC, 0.94 to 0.98 in pre-treatment; 0.95 to 0.98 in post-treatment). Measurements at the 6-week post-treatment follow-up demonstrated a statistically significant skin reduction in all six of the measured parameters. A simple skin measurement method requiring minimal instrumentation can quantitatively evaluate skin shrinkage associated with non-invasive skin-tightening devices.

Background Compared with other imaging modalities, ultrasound is relatively deeply penetrating and can be used to evaluate deep dermal and subcutaneous structures. Objective Image skin thickness of the face and neck using high-frequency diagnostic ultrasound devices. Materials and methods Skin overlying 20 different predesignated face and neck anatomic sites in 32 individuals was imaged using 2 commercially available high-frequency diagnostic ultrasound devices, a dedicated imaging device and a diagnostic device bundled with a therapeutic device. At each site, the subcutaneous and combined epidermal and dermal layer thicknesses were assessed by blinded expert raters. Results Similar skin thickness measurements were obtained. Notably, subcutaneous fat depth was measured to be 0.2 cm at the forehead; 0.5 cm at the mental eminence; and 0.6 cm at the submental, supraglenoid, and temporal regions. The combined epidermal and dermal thickness was approximately 0.1 cm at the zygomatic process, suborbital area, inferior malar region, gonion, supraglenoid area, and nasolabial-buccal, and nasolabial fold regions. Conclusion This is the first study using high-resolution superficial diagnostic ultrasound to map skin thickness of the face and neck at standard anatomic locations. Ultrasound is an inexpensive, noninvasive, and convenient means to monitor dermatologic conditions and guide their treatment.

IMPORTANCE: Although hyaluronidase is known to remove hyaluronic acid fillers, use of low doses has not been well studied. OBJECTIVE: To assess the effectiveness and dose-related effect of small quantities of hyaluronidase to treat hyaluronic acid filler nodules. DESIGN, SETTING, AND PARTICIPANTS: Split-arm, parallel-group, randomized clinical trial at an urban academic center. Participants were 9 healthy women. Recruitment and follow-up occurred from February 2013 to March 2014; data analysis occurred from February to July 2016. INTERVENTIONS: Each participant received aliquots (buttons) of either of 2 types of hyaluronic acid fillers into bilateral upper inner arms, respectively. At 1, 2, and 3 weeks each button was treated with a constant volume (0.1 mL) of variable-dose hyaluronidase (1.5, 3.0, or 9.0 U per 0.1 mL) or saline control. MAIN OUTCOMES AND MEASURES: Both a blinded dermatologist and the participant independently assessed detectability. RESULTS: Seventy-two treatment sites on 9 women (mean [SD] age, 45.8 [15.7] years) received all interventions and were analyzed. There was a significant difference in physician rater assessment between saline and hyaluronidase at 4 weeks (visual detection: mean difference = 1.15; 95% CI, 0.46-1.80; P

Importance Microcystic adnexal carcinoma (MAC) occurs primarily in older adults of white race/ethnicity on sun-exposed skin of the head and neck. There are no formal guiding principles based on expert review of the evidence to assist clinicians in providing the highest-quality care for patients. Objective To develop recommendations for the care of adults with MAC. Evidence review A systematic review of the literature (1990 to June 2018) was performed using MEDLINE, Embase, Web of Science, and the Cochrane Library. The keywords searched were microcystic adnexal carcinoma, sclerosing sweat gland carcinoma, sclerosing sweat duct carcinoma, syringomatous carcinoma, malignant syringoma, sweat gland carcinoma with syringomatous features, locally aggressive adnexal carcinoma, and combined adnexal tumor. A multidisciplinary expert committee critically evaluated the literature to create recommendations for clinical practice. Statistical analysis was used to estimate optimal surgical margins. Findings In total, 55 studies met our inclusion criteria. The mean age of 1968 patients across the studies was 61.8 years; 54.1% were women. Recommendations were generated for diagnosis, treatment, and follow-up of MAC. There are 5 key findings of the expert committee based on the available evidence: (1) A suspect skin lesion requires a deep biopsy that includes subcutis. (2) MAC confined to the skin is best treated by surgery that examines the surrounding and deep edges of the tissue removed (Mohs micrographic surgery or complete circumferential peripheral and deep margin assessment). (3) Radiotherapy can be considered as an adjuvant for MAC at high risk for recurrence, surgically unresectable tumors, or patients who cannot have surgery for medical reasons. (4) Patients should be seen by a physician familiar with MAC every 6 to 12 months for the first 5 years after treatment. Patient education on photoprotection, periodic skin self-examination, postoperative healing, and the possible normal changes in local sensation (eg, initial hyperalgesia) should be considered. (5) There is limited evidence to guide the treatment of metastasis in MAC due to its rarity. Limitations of our findings are that the medical literature on MAC comprises only retrospective reviews and descriptions of individual patients and there are no controlled studies to guide management. Conclusions and relevance The presented clinical practice guidelines provide an outline for the diagnosis and management of MAC. Future efforts using multi-institutional registries may improve our understanding of the natural history of the disease in patients with lymph node or nerve involvement, the role of radiotherapy, and the treatment of metastatic MAC with drug therapy.

SummaryBackground Forehead and glabella rhytides are treated mostly with neurotoxins, although some practitioners prefer the concurrent use of fillers. It has been suggested that combination treatments can result in a better overall improvement. Aims To compare the safety and effectiveness of treatment of forehead and glabellar lines with botulinum toxin A alone versus botulinum toxin A and filler. Methods Split-face, randomized control trial. Twenty subjects with forehead/glabellar rhytide complex (static and dynamic creases) enrolled. Subjects were randomized and injected with botulinum toxin alone on one side of the forehead/glabella and hyaluronic acid filler followed by botulinum toxin on the other side. Blinded ratings were obtained to assess the effectiveness of treatment for static and dynamic rhytides, respectively, at 2-week, 6-week, 3-month, and 6-month follow-up visits. Subjects performed a self-evaluation at the end of the study. Adverse events were recorded. Results Ratings of both treatments showed comparable efficacy, with 100% of subjects experiencing improvement from baseline regardless of treatment type at weeks 2, 6, and 12. Combination treatment produced longer-lasting results in dynamic forehead wrinkles, and greater static and dynamic wrinkle reduction in the glabella at week 24. Subject self-evaluations showed that both treatments were effective, with a nominal preference for combination treatment. Conclusions Glabella and forehead lines can be effectively and safely reduced with neurotoxin alone as well as neurotoxin in combination with fillers. Combination treatment may provide a slightly better cumulative benefit and also increase the persistence of effect.

Purpose Setup deviations of a craniospinal irradiation (CSI) patient cohort previously treated with helical tomotherapy were used to derive the optimal planning target volume (PTV) margin for CSI patients treated in the supine position. Methods and Materials The daily setup shifts of 27 CSI tomotherapy patients as determined using pretreatment megavoltage computed tomography verification for a total of 454 fractions were evaluated. Translational displacements in the mediolateral (ML), craniocaudal (CC), and anteroposterior (AP) directions were used to assess the systematic and random setup errors, and to derive the PTV margin required when daily image guidance is unavailable. Results The individual patient mean shifts and the corresponding standard deviations in the ML, CC, and AP directions were −0.5 ± 2.1 mm, 1.0 ± 2.7 mm, and 0.7 ± 1.1 mm, respectively. The random errors in the corresponding directions were 1.9 mm, 1.9 mm, and 2.2 mm. The PTV margins required in the absence of daily imaging were 3.7 mm to the right, 4.7 mm to the left, 4.4 mm inferior, 6.4 mm superior, 1.6 mm posterior, and 3.0 mm anterior. Conclusions The current PTV margin of 3.0 mm is sufficient to ensure clinical target volume coverage for CSI tomotherapy patients treated with daily megavoltage computed tomography imaging. When pretreatment verification imaging is not used to lower the setup uncertainty, a larger PTV margin of up to 6.4 mm in the CC direction will be needed.

Background Floaters are dislodged pieces of tumor tissue than can obscure Mohs micrographic surgery (MMS) frozen sections and confound their interpretation. Objective To understand the common causes of floaters and identify management strategies. Methods An initial virtual consensus conference of Mohs surgeons based on a 60-item questionnaire. Data were validated in interviews with randomly selected Mohs surgeons. Results Based on retrospective reporting of 230 surgeon-years and 170,404 cases of MMS by 26 surgeons, the mean rate of floaters per tumor treated was 1.8%, and the rate of floaters per tissue block was 0.70%. Not wiping blades between cuts when a stage is separated into subunits can predispose to floaters. There was also strong consensus that basal cell carcinomas, ulcerated tumors, and tissue from the first stage were more likely to yield floaters. There is little consensus on how to manage floaters, with possibilities including taking additional sections, taking an additional stage, or simply noting the floater. Conclusion Floaters are not rare and can complicate MMS margin assessment. There is significant expert consensus regarding the causes of floaters and the tissue features that may predispose to them. Floaters may be prevented by minimizing their likely causes. There is less consensus on what to do with a floater.

Background Facial erythema is a common symptom that responds to vascular laser treatment, but there are few comparative studies. Objective We sought to compare the effectiveness of microsecond 1064-nm neodymium:yttrium-aluminum-garnet (Nd:YAG) laser with nonpurpuragenic 595-nm pulsed dye laser (PDL) for diffuse facial erythema. Methods This was a split-face, double-blind randomized controlled trial. Bilateral cheeks received 4 treatments each at one month intervals with PDL or Nd:YAG. Spectrophotometer measurements, digital photographs, pain scores, and patient preferences were recorded. Results Sixteen patients enrolled and 2 dropped out. Fourteen patients, all skin types I to III, 57% women, mean age 42 years, completed the study and were analyzed. Spectrophotometer readings changed after both PDL (8.9%) and Nd:YAG (2.5%), but varied by treatment type, with PDL reducing facial redness 6.4% more from baseline than Nd:YAG ( P = .0199; 95% confidence interval −11.6 to −1.2). Pain varied ( P = .0028), with Nd:YAG associated with less pain, at 3.07, than PDL at 3.87. Subjects rated redness as improved by 52% as a result of PDL, and 34% as a result of Nd:YAG ( P = .031; 95% confidence interval −34.6 to −1.94). No serious adverse events were observed. Limitations Lasers settings are not standardized across devices. Conclusion Facial erythema is safely and effectively treated with PDL and Nd:YAG. Nonpupuragenic PDL may be more effective for lighter-skinned patients, but microsecond Nd:YAG may be less painful.

Background Botulinum toxin injections and suction-curettage have been separately shown to be effective in treating axillary hyperhidrosis but have not been compared in the same patients. Objective We sought to compare effectiveness of suction-curettage versus neurotoxin for the treatment of axillary hyperhidrosis. Methods Each of 20 patients was randomized to receive toxin injections to one axilla and suction-curettage to the contralateral axilla. The primary outcome measure was reduction of sweat rate measured by gravimetry, and the secondary measure was quality of life as measured by a patient-directed questionnaire. Results At 3 months posttreatment, toxin injections decreased baseline resting sweat production by 72.1% versus 60.4% ( P = .29) for suction-curettage, and baseline exercise-induced sweat production by 73.8% versus 58.8% ( P = .10). When patients were stratified into the categories of light and heavy sweaters, there was a difference among heavy sweaters, with exercise-induced sweat production lower by 10.48 mg/min or 34.3% ( P = .0025) at toxin-treated sites. Compared with suction-curettage, toxin also resulted in greater improvements in quality of life by 0.80 points ( P = .0002) and 0.90 points ( P = .0017) at 3 and 6 months posttreatment, respectively, as measured by the patient questionnaire. Limitations The follow-up period was limited to 6 months. Conclusions By objective measures 3 months after treatment, neurotoxin injections are nominally more effective than suction-curettage in all cases, and markedly more effective in heavy sweaters. Patients have a very significant preference for neurotoxin injections at 3 months, and this is maintained at 6 months.

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.

Facial aging is a concern for many patients. Wrinkles, loss of volume, and discoloration are common physical manifestations of aging skin. Genetic heritage, prior ultraviolet light exposure, and Fitzpatrick skin type may be associated with the rate and type of facial aging. Although many clinical trials assess the correlates of skin aging, there is heterogeneity in the outcomes assessed, which limits the quality of evaluation and comparison of treatment modalities. To address the inconsistency in outcomes, in this project we will develop a core set of outcomes that are to be evaluated in all clinical trials relevant to facial aging. A long list of measureable outcomes will be created from four sources: (1) systematic medical literature review, (2) patient interviews, (3) other published sources, and (4) stakeholder involvement. Two rounds of Delphi processes with homogeneous groups of physicians and patients will be performed to prioritize and condense the list. At a consensus meeting attended by physicians, patients, and stakeholders, outcomes will be further condensed on the basis of participant scores. By the end of the meeting, members will vote and decide on a final recommended set of core outcomes. Subsequent to this, specific measures will be selected or created to assess these outcomes. The aim of this study is to develop a core outcome set and relevant measures for clinical trials relevant to facial aging. We hope to improve the reliability and consistency of outcome reporting of skin aging, thereby enabling improved evaluation of treatment efficacy and patient satisfaction.
