Purpose: Standard treatment for basal cell carcinoma (BCC) is surgical resection. However, a subset of locally advanced BCCs may be unresectable, or surgery would result in unacceptable functional or cosmetic defects. Outcomes after definitive radiation therapy for locally advanced BCC in the contemporary era are not well established.

Objective: To determine LRR after excision of DM and evaluate factors affecting LRR.
Materials And Methods: Systematic review of the PubMed, Embase, and Web of Science databases was performed to identify studies reporting local recurrence after excision of DM with conventional wide local excision (WLE), Mohs micrographic surgery (MMS), or staged excision (SE).
Background: Mohs micrographic surgery (MMS) for cutaneous melanoma is becoming more prevalent, but surgical technique varies.
Objective: To define variations in published techniques for MMS for melanoma.
Methods And Materials: A systematic review was performed of PubMed, EMBASE, and Scopus databases to identify all articles describing surgical techniques for MMS for melanoma.
Importance: To curtail the opioid epidemic, physicians have been advised to limit opioid prescriptions.
Objective: To characterize the frequency and changes over time (2009-2020) of opioid prescriptions following Mohs micrographic surgery.
Design, Setting, And Participants: This cross-sectional study using Optum Clinformatics DataMart (Optum CDM), a nationally representative insurance claims database, included patients aged 18 years and older who had Mohs micrographic surgery insurance claims in the Optum CDM database from 2009 to 2020.
Background: Sentinel lymph node biopsy (SLNB) has not been studied for invasive melanomas treated with Mohs micrographic surgery using frozen-section MART-1 immunohistochemical stains (MMS-IHC). The primary objective of this study was to assess the accuracy and compliance with National Comprehensive Cancer Network (NCCN) guidelines for SLNB in a cohort of patients who had invasive melanoma treated with MMS-IHC.
Methods: This retrospective cohort study included all patients who had primary, invasive, cutaneous melanomas treated with MMS-IHC at a single academic center between March 2006 and April 2018.
Background: The gold standard of treatment for cutaneous squamous cell carcinoma (cSCC) is surgery radiation therapy (RT) is used selectively as definitive treatment for low-risk tumors or as adjuvant/salvage treatment for high-risk tumors. There is a lack of standardized studies evaluating the efficacy of RT in either clinical scenario.
Objective: To determine the efficacy of primary and adjuvant/salvage RT for the treatment of cSCC.
Background: Local recurrence rates (LRRs) after Mohs micrographic surgery (MMS) for male genital cancers have been reported in only a few small case series, and patient-reported outcomes (PROs) have not been studied.
Objective: To determine the LRR and PROs after MMS for male genital skin cancers.
Methods: Retrospective review of all male genital skin cancers removed with MMS between 2008 and 2019 at an academic center.
Background: Insurance companies have implemented new policies including excessive prior authorization (PA) requirements, high-deductible plans, and complicated billing structures in an effort to curb rising health care costs. Studies investigating the real-time impact on providers and patients are emerging, but few within the field of dermatology have been published.
Objective: To assess the impact of cost-cutting policies on patients and physicians.
The effect of size and release kinetics of doxorubicin-nanoparticles on anti-tumor efficacy was evaluated in a panel of human cancer cell lines, including triple-negative breast cancer (TNBC) cells that frequently demonstrate resistance to doxorubicin. Different nano-formulations of sol-gel-based Doxorubicin containing nanoparticles were synthesized. Increased cell kill in chemoreffactory triple-negative breast cancer cells was associated with the smallest size of nanoparticles and the slowest release of Dox.

Inflammatory vasculitis can mimic infection; however, distinction is critical for the timely institution of appropriate therapy. We present two patients who had generalized polymorphous eruptions whose cutaneous pathology showed vasculitis with unusual haloed yeast-like cells within the inflammatory infiltrate, mimicking Cryptococcus.

Aims: Review the spectrum of procedural techniques for treatment of rhinophyma with a focus on the advantages and disadvantages of each modality.
Methods: A comprehensive literature search was conducted using the search terms "rhinophyma," "treatment," and "surgery" in PubMed.
Background: Current knowledge of angiolymphoid hyperplasia with eosinophilia (ALHE) derives from retrospective reports and case series, leading to a nonevidence-based treatment approach.
Objective: We sought to systematically review the literature relating to cutaneous ALHE to estimate its epidemiology and treatment outcomes.
Methods: A literature search of PubMed, EMBASE, Web of Science, and Google Scholar was conducted.
Advances in surgical technology have allowed for previously unconsidered therapeutic interventions. However, the complexity and invasiveness of surgical procedures are not without adverse consequences. Nitric oxide's fundamental role in a host of physiological processes, including angiogenesis, wound and bone healing, thromboresistance, smooth muscle relaxation and inflammation makes it a significant player in accelerating wound healing and mitigating the inflammation of ischemia reperfusion injury common to surgical procedures.

Therefore, therapeutics targeting both the stimulus and the cascade would be ideal. Nitric oxide (NO), a potent biological messenger, has documented broad-spectrum antimicrobial and immunomodulatory properties.

Its use against Trichophyton rubrum, a dermatophytic fungus with increasing incidence and resistance, has not been well characterized. Our aim was to evaluate the mechanism of action of aPI against T.

It was previously suggested that the mechanism by which Biafine topical emulsion improves wound healing is via enhanced macrophage infiltration into the wound bed. The purpose of this study was to confirm this observation through gross and histologic assessments of wound healing using murine full-thickness excisional and burn wound models, and compare to common standards, Vaseline and silver sulfadiazine (SSD).

In this study, we identify the previously uncharacterized microtubule-severing enzyme, Fidgetin-like 2 (FL2), as a fundamental regulator of cell migration that can be targeted in vivo using nanoparticle-encapsulated small interfering RNA (siRNA) to promote wound closure and regeneration. In vitro, depletion of FL2 from mammalian tissue culture cells results in a more than twofold increase in the rate of cell movement, in part due to a significant increase in directional motility.

Previously, NO-releasing nanoparticles (NO-np) demonstrated increased antimicrobial activity when combined with glutathione (GSH) due to formation of S-nitrosoglutathione (GSNO), a transnitrosylating agent. To capitalize on this finding, we incorporated the thiol-containing ACE-inhibitor, captopril, with NO-np to form SNO-CAP-np, nanoparticles that both release NO and form S-nitrosocaptopril.

Agents commonly used to treat burn wound infection are limited by toxicity, incomplete microbial coverage, inadequate penetration, and rising resistance. Curcumin is a naturally derived substance with innate antimicrobial and wound healing properties.
View Article and Find Full Text PDFHerbal products have steadily gained popularity as alternatives to conventional, synthetic medications and are sought after by patients for the treatment of chronic dermatologic diseases and for cosmeceutical use. The production and distribution of botanical extracts is largely unregulated and therefore extensive research into their mechanism of action, safety, physiologic stability, and optimal dosing has been overlooked. One of the major pathways through which natural supplements, particularly polyphenols, act is via inhibition of oxidative stress and its downstream mediators.
