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.

Atopic dermatitis, commonly known as eczema, is a chronic inflammatory dermatosis that can affect individuals from infancy to adulthood. Also referred to as "the itch that rashes," atopic dermatitis is classically associated with significant pruritus that is accompanied by characteristic cutaneous and other clinical findings. The diagnosis of atopic dermatitis can be challenging due to the wide range of clinical presentations based on patient factors such as age, skin type, ethnicity, and other comorbid conditions.

NUT carcinoma (NC) is a rare and aggressive neoplasm associated with a poor prognosis. NC is characterized by a NUTM1- rearrangement on chromosome 15q14, commonly fused with the BRD4 or BRD3 gene . A rare subset of NC defined by fusion of NUTM1 with the MGA gene has been identified, showing mesenchymal differentiation on histology.

An aqueous emulsion of conducting polymer is commonly applied on a substrate to form a coating after drying. The coating, however, disintegrates in water. This paper reports a coating prepared using a mixture of two emulsions: an aqueous emulsion of conducting polymer, and an aqueous emulsion of hydrophobic and rubbery chains copolymerized with silane coupling agents.

Low-dose radiotherapy (LDRT), defined in this study as 2 fractions of 4 Gy delivered on consecutive days, is an effective option for local palliation of mycosis fungoides (MF), but its efficacy for tumoral lesions (TL) needs investigation. We assessed response and local control (LC) rates for patients treated with LDRT for MF and compared these outcomes between TL and non-TL. A total of 73 lesions in 18 patients treated with LDRT between 2013-2020 were analyzed.

Hydrogels are being developed to bear loads. Applications include artificial tendons and muscles, which require high strength to bear loads and low hysteresis to reduce energy loss. However, simultaneously achieving high strength and low hysteresis has been challenging.

Importance: The pathophysiology of interstitial cystitis/bladder pain syndrome (IC/BPS) is imperfectly understood. Recent studies reported that small-fiber polyneuropathy (SFPN) is common in fibromyalgia, a condition commonly comorbid with IC/BPS.

Objective: The objective of this study was to determine the prevalence of SFPN in a large cohort of IC/BPS patients.

Airbags can be lifesaving during a motor vehicle accident (MVA), but airbag deployment has been the cause of dermatologic injuries including irritant dermatitis, as well as thermal, friction, and chemical burns. A highly corrosive alkaline aerosol composed of sodium hydroxide, sodium bicarbonate, and metallic oxides is released during airbag deployment. We present the case of a 35-year-old man who developed a bullous reaction to released by-products from airbag deployment during an MVA.

A variety of autonomous oscillations in nature such as heartbeats and some biochemical reactions have been widely studied and utilized for applications in the fields of bioscience and engineering. Here, we report a unique phenomenon of moisture-induced electrical potential oscillations on polymers, poly([2-(methacryloyloxy)ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide-co-acrylic acid), during the diffusion of water molecules. Chemical reactions are modeled by kinetic simulations while system dynamic equations and the stability matrix are analyzed to show the chaotic nature of the system which oscillates with hidden attractors to induce the autonomous surface potential oscillation.

Objectives: Health systems and provider groups currently lack a systematic mechanism to evaluate the financial implications of value-based alternative payments. We sought to develop a method to prospectively quantify the financial implications, including risk and uncertainty of (1) transitioning from a fee-for-service to an episode-based payment model and (2) modifying episode-specific clinical cost drivers. Finally, we highlight practical applications for the model to help facilitate stakeholder engagement in the transition to value-based payment models.

Case Presentation: An elderly man presented to the emergency department after a fall from a 15-foot height. Initial examination revealed signs of head and neck trauma without airway compromise. Computed tomography imaging identified cervical fractures at the first and second level with a retropharyngeal hematoma.

Introduction: As left ventricular assist devices (LVADs) become more prevalent in the treatment of patients with end-stage heart failure, emergency physicians must become experts in the management and resuscitation of patients with LVADs. As with other high-acuity, low-occurrence scenarios, managing the unstable LVAD patient makes for an ideal topic for simulation-based resident education.

Methods: By incorporating a high-fidelity HeartMate 3 LVAD task trainer, our program developed and executed a novel LVAD simulation activity for our emergency medicine resident physicians.
