Association of Staphylococcus aureus Colonization With Severity of Acute Radiation Dermatitis in Patients With Breast or Head and Neck Cancer.

Importance: Pathogenesis of acute radiation dermatitis (ARD) is not completely understood. Pro-inflammatory cutaneous bacteria may contribute to cutaneous inflammation after radiation therapy. Objective: To evaluate whether nasal colonization with Staphylococcus aureus (SA) before radiation therapy is associated with ARD severity in patients with breast or head and neck cancer. Design, Setting, and Participants: This prospective cohort study with observers blinded to colonization status was conducted from July 2017 to May 2018 at an urban academic cancer center. Patients aged 18 years or older with breast or head and neck cancer and plans for fractionated radiation therapy (≥15 fractions) with curative intent were enrolled via convenience sampling. Data were analyzed from September to October 2018. Exposures: Staphylococcus aureus colonization status before radiation therapy (baseline). Main Outcomes and Measures: The primary outcome was ARD grade using the Common Terminology Criteria for Adverse Event Reporting, version 4.03. Results: Among 76 patients analyzed, mean (SD) age was 58.5 (12.6) years and 56 (73.7%) were female. All 76 patients developed ARD: 47 (61.8%) with grade 1, 22 (28.9%) with grade 2, and 7 (9.2%) with grade 3. The prevalence of baseline nasal SA colonization was higher among patients who developed grade 2 or higher ARD compared with those who developed grade 1 ARD (10 of 29 [34.5%] vs 6 of 47 [12.8%]; P = .02, by χ2 test). Conclusions and Relevance: In this cohort study, baseline nasal SA colonization was associated with development of grade 2 or higher ARD in patients with breast or head and neck cancer. The findings suggest that SA colonization may play a role in the pathogenesis of ARD.

The rule of 10s versus the rule of 2s: High complication rates after conventional excision with postoperative margin assessment of specialty site versus trunk and proximal extremity melanomas.

Specialty site melanomas on the head and neck, hands and feet, genitalia, and pretibial leg have higher rates of surgical complications after conventional excision with postoperative margin assessment (CE-POMA) compared with trunk and proximal extremity melanomas. The rule of 10s describes complication rates after CE-POMA of specialty site melanomas: ∼10% risk for upstaging, ∼10% risk for positive excision margins, ∼10% risk for local recurrence, and ∼10-fold increased likelihood of reconstruction with a flap or graft. Trunk and proximal extremity melanomas encounter these complications at a lower rate, according to the rule of 2s. Mohs micrographic surgery (MMS) with frozen section melanocytic immunostains (MMS-I) and slow Mohs with paraffin sections decrease complications of surgery of specialty site melanomas by detecting upstaging and confirming complete tumor removal with comprehensive microscopic margin assessment before reconstruction. This article reviews information important for counseling melanoma patients about surgical treatment options and for developing consensus guidelines with clear indications for MMS-I or slow Mohs.

Relationship Between Scholarly Activity and Postgraduate Career Choice: A Bibliometric Analysis of the 2017 Diplomates of the American Board of Dermatology.

BACKGROUND: Scholarly productivity is an assessment metric for dermatology residents and faculty. How the bibliometric h-index, a publicly available metric that incorporates the quantity and quality of publications, relates to early career choices of dermatologists has not been investigated. OBJECTIVE: We determined the h-indices of the 2017 diplomates of the American Board of Dermatology to ascertain its association with career choice. METHODS: A cross-sectional analysis was performed using the published list of the 2017 diplomates. Gender and PhD status were compiled. The Scopus database was queried for publications and h-indices. The primary outcome was the pursuit of an academic position, nonacademic position, or fellowship after board certification. RESULTS: Among 475 (96%) diplomates, the median (range) h-index was 2 (0-14). Those with MD and PhD degrees had greater h-indices (6.4 ± 3.1 vs. 2.3 ± 2.3, P < .05). There was a difference (P < .05) in h-index between diplomates pursuing an academic position (3.6 ± 3.1), non-procedural fellowship (3.3 ± 3.1), procedural fellowship (2.5 ± 2.0), and non-academic position (2.1 ± 2.1). CONCLUSIONS: The h-index quantifies academic productivity and may predict early career choices in dermatology.

Estrogen-deficient skin: The role of topical therapy.

Menopause is a major turning point in a woman's life that is characterized by declining ovarian function and decreased serum estrogen levels. The resulting hormonal changes particularly affect the skin, with postmenopausal symptoms such as loss of structural architecture and increased propensity to damage becoming rapidly noticeable. Interestingly, studies have shown that estrogen deprivation in postmenopausal conditions accelerates many skin changes, including dryness, atrophy, fine wrinkling, and poor wound healing. Thus, the effects of low estrogen on the skin are an important endogenous cause of aging skin in women, yet topical treatment strategies that target cutaneous symptoms are limited. The goal of this article is to provide an overview of the role of estrogen in the skin and changes associated with estrogen deficiency, as well as review alternatives to systemic estrogen therapy and describe the effects of these interventions on cutaneous aging in postmenopausal skin. Specifically, clinical studies that utilize topical estrogens and topical isoflavones, which are soy-derived compounds that interact with estrogen receptors, are discussed.

A National Survey of Medical Coding and Billing Training in United States Dermatology Residency Programs.

BACKGROUND: Due to frequent changes in medical coding systems, billing for outpatient visits through Evaluation and Management (E & M) services has become increasingly complicated. As a result, physicians often bill improperly, costing the United States health care system billions of dollars annually. Despite the importance of proper documentation, medical coding and billing is largely ignored during residency training. OBJECTIVE: Assess the exposure to and quality of medical coding and billing training in dermatology residency programs. METHODS: A questionnaire was distributed to dermatology programs in the United States consisting of questions pertaining to didactic education for, experience with, and resident knowledge of medical coding and billing. RESULTS: 138/443 dermatology residents participated (31.2% response rate). 79% of residents reported receiving some type of formal training. Nearly 89% reported personally billing patient visits to some degree, with 41.3% billing for 100% of outpatient visits. Over 75% of residents were able to answer basic billing questions and 70% correctly billed a patient visit when given a complex clinical scenario. Despite these results, only 37% of residents reported feeling confident in their billing abilities. Lastly, 94.9% of respondents believed medical coding and billing should be integrated into dermatology training curriculums. CONCLUSIONS: The majority of dermatology residents have opportunities to learn medical coding and billing through didactics and clinical experiences. Many residents were able to answer correctly questions that tested their basic knowledge of E&M coding. These results are encouraging and reflect the recognition of the importance of medical coding and billing training during residency. J Drugs Dermatol. 2018;17(6):678-682.

Beyond Traditional Treatment: The Importance of Psychosocial Therapy in Vitiligo.

Vitiligo is an acquired depigmentation disorder of the skin. Patients with vitiligo often face a challenging disease course, having to cope with a condition that is known to be physically disfiguring, psychologically devastating, and socially stigmatizing. Although an extensive amount of research has been directed towards the dermatologic treatment of vitiligo, an overall lack of data exists investigating treatment of the psychological and emotional burden of patients with vitiligo. This paper reviews the literature for treatment options in patients with vitiligo that specifically target the psychosocial domain. Despite being limited in quantity, several studies have proven the benefits of adjuvant care in the form of group therapy, cognitive behavioral therapy, and self-help programs. Although preliminary evidence is promising, larger prospective studies are needed to further define the role of these psychosocial interventions before integrating them in a more official capacity into the standard of care for patients with vitiligo. Because of the considerable impact of vitiligo beyond its physical symptoms, dermatologists ought to consider the utility of adjuvant therapies to adequately address impairments in self-esteem, body image, and quality of life in patients with vitiligo.

There are currently 4 leading modalities used for noninvasive body contouring: cryolipolysis, radiofrequency, high-intensity focused ultrasound, and laser therapy. This article provides an overview of each modality.

Cutaneous toxicity as a predictive biomarker for clinical outcome in patients receiving anticancer therapy.

The relationship between treatment outcome and cutaneous toxicity induced by anticancer therapy has gained attention in the past decade. In this article, we have provided an overview of the 3 main classes of anticancer agents-specifically, molecularly targeted kinase inhibitors, immune checkpoint inhibitors, and cytotoxic chemotherapeutics-and described the data evaluating the association between cutaneous toxicity induced by these agents and survival benefit. Although preliminary studies are promising with regard to the potential role of cutaneous toxicities as a surrogate biomarker of efficacy of treatment, larger prospective studies are needed to confirm this relationship. Dermatologists have a unique opportunity to collaborate with oncologists in the multidisciplinary treatment paradigm by helping to identify and manage these dermatologic events in patients with cancer. A heightened awareness of these toxicities is critical, as it can potentially allow recognition of the efficacy of anticancer therapy and may influence treatment decisions and patient outcomes.

Prescription Opioid Use among Opioid-Naive Women Undergoing Immediate Breast Reconstruction.

BACKGROUND: Cancer patients may be particularly vulnerable to the deleterious effects of prolonged opioid use. The authors explored the factors that influence postoperative opioid prescription fills among women following postmastectomy reconstruction. METHODS: Using the Truven Health MarketScan Research Databases, the authors identified a cohort of 4113 opioid-naive patients undergoing mastectomy and immediate breast reconstruction between January of 2010 and August of 2014. Outcomes included average daily oral morphine equivalents and the incidence of prolonged opioid fills (between 90 and 120 days after surgery). Using multivariable regression, the authors examined the effect of patient demographic characteristics, reconstructive technique, comorbid medical and psychiatric conditions, and postoperative complications on outcome variables. RESULTS: In this cohort, 90 percent of patients filled opioid prescriptions perioperatively, and 10 percent continued to fill prescriptions beyond 3 months after surgery. Patients with depression were more likely to fill prescriptions of higher average daily oral morphine equivalents (74.2 mg versus 58.3 mg; p < 0.01), and patients with anxiety were more likely to fill opioids for prolonged periods (13.4 percent versus 9.1 percent; p < 0.01). Patients undergoing autologous free flap reconstruction were less likely to fill prescriptions for a prolonged period following surgery (5.9 percent versus 10.2 percent; p < 0.001). CONCLUSIONS: Prescription opioid fills are common following breast reconstruction, and 10 percent of all patients continue to fill opioid prescriptions beyond 3 months after surgery. Prolonged fills are influenced by both patient factors and surgical procedure, and attention should be directed toward identifying opioid alternatives when possible. CLINCAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Validation of the V(max) metabolic cart in a simulated pediatric model.

BACKGROUND: The ability to accurately measure resting energy expenditure (REE) using indirect calorimetry, often referred to as the "gold standard" in nutrition needs assessment, is important given the well-established positive correlation between patient outcome and proportion of the nutrition goal met. While many studies have been done to compare various metabolic carts with one another, the literature lacks a large simulator-based validation of any metabolic cart system. MATERIALS AND METHODS: In the present study, 8 specifically trained staff members independently conducted 10 simulation trials each using the V(max) Encore metabolic analyzer in conjunction with a metabolic calibration system, which simulates patient metabolic activity, to validate the accuracy of the V(max) Encore across a wide range of simulated metabolic conditions. Testing conditions consisted of incremental adjustments in calibrated gas infusion with a consistently set tidal volume and respiratory rate. RESULTS: There was a strong, statistically significant correlation between the predicted and actual VO2 and VCO2 data (VO2, R (2) = 0.998; VCO2, R (2) = 0.997). In addition, we observed no significant difference between individuals performing these trials (VO2, P = 1.000, F = 0.021, df = 79; VCO2, P = 1.000, F = 0.030, df = 79). CONCLUSIONS: This study is the first to report on such a wide spectrum of metabolic activity (50-2000 kcal REE) using a calibrated bench model and validates the accuracy, reproducibility, and use of the V(max) Encore metabolic cart.
