Article Synopsis
  • There is currently no objective clinical tool for primary care physicians or dermatologists to identify potentially cancerous skin lesions.
  • The study explored the use of multispectral autofluorescence lifetime imaging (maFLIM) dermoscopy to differentiate between malignant and benign pigmented skin lesions through advanced imaging techniques and machine learning models.
  • The deep neural network model outperformed others, achieving a sensitivity of 76.84% and specificity of 78.29%, indicating that maFLIM dermoscopy could help doctors in early detection and reduce unnecessary biopsies.

Article Synopsis
  • Mohs micrographic surgery (MMS) is an effective treatment for melanoma in situ (MIS), but inconsistent surgical techniques make it hard to apply current data broadly.
  • To standardize MMS techniques for MIS in future studies, a modified Delphi method was used, involving expert input through voting on various surgical approaches.
  • The study generated 8 consensus recommendations, with five agreed upon in the first round and the others in the second, aimed at providing uniform guidelines to improve future clinical trials.

This case presentation describes and justifies the use of petrolatum gauze that is impregnated with 3% bismuth tribromophenate (Xeroform) as a low-cost and effective alternative for synthetic skin grafts. Herein, we discuss clinical trials that demonstrate the benefits of utilizing Xeroform for second-intention healing as well as photographs of a case in which the authors used this method and followed a patient's wound-healing process over time.

Significance: Accurate early diagnosis of malignant skin lesions is critical in providing adequate and timely treatment; unfortunately, initial clinical evaluation of similar-looking benign and malignant skin lesions can result in missed diagnosis of malignant lesions and unnecessary biopsy of benign ones.

Aim: To develop and validate a label-free and objective image-guided strategy for the clinical evaluation of suspicious pigmented skin lesions based on multispectral autofluorescence lifetime imaging (maFLIM) dermoscopy.

Approach: We tested the hypothesis that maFLIM-derived autofluorescence global features can be used in machine-learning (ML) models to discriminate malignant from benign pigmented skin lesions.

In this study, we report a four-year-old male with D-2-hydroxyglutaric aciduria (D2HA) and enchondromatosis with a prior history of hyperpigmented, segmental whorls and streaks on his abdomen who later presented with an eruption of angiokeratoma circumscriptum within a similar distribution. His condition can likely be explained by underlying somatic mosaicism; however, a unifying culprit gene mutation has not yet been identified. To date, only 10 reported cases of D2HA with enchondromatosis are available in the literature with three reported skin findings.

Common challenges associated with split-thickness skin graft (STSG) donor site wounds include slow healing times and poor scar cosmesis. The technique described here improves these shortcomings by utilizing a Weck knife with adjustable thickness controls to harvest STSGs from the scalp.

Background: Recently, the safety of lidocaine plus epinephrine use in outpatient surgery has come under scrutiny despite its long history of use in outpatient dermatologic procedures and surgeries.

Objective: To assess the frequency of crash cart and other emergency interventions during Mohs micrographic surgery when lidocaine plus epinephrine is used as a local anesthetic and evaluate patient comorbidities associated with these events.

Materials And Methods: A retrospective chart review was conducted in an outpatient Mohs micrographic surgery clinic.

Finasteride and dutasteride, both 5-alpha reductase inhibitors, are considered first-line treatment for androgenetic hair loss in men and used increasingly in women. In each case, patients are expected to take the medications indefinitely despite the lack of research regarding long-term adverse effects. Concerns regarding the adverse effects of these medications has led the United States National Institutes of Health to add a link for post-finasteride syndrome to its Genetic and Rare Disease Information Center.

Molecular interactions of optical clearing agents were investigated using a combination of molecular dynamics (MD) simulations and optical spectroscopy. For a series of sugar alcohols with low to high optical clearing potential, Raman spectroscopy and integrating sphere measurements were used to quantitatively characterize tissue water loss and reduction in light scattering following agent exposures. The rate of tissue water loss was found to correlate with agent optical clearing potential, but equivalent tissue optical clearing was measured in native and fixed tissue in vitro, given long-enough exposure times to the polyol series.
