RESUMO

We have developed a portable confocal microscope (PCM) that uses an inexpensive near-infrared LED as the light source. Use of the spatially incoherent light source significantly reduced the speckle contrast. The PCM device was manufactured at the material cost of approximately $5000 and weighed only 1 kg. Lateral and axial resolutions were measured as 1.6 and 6.0 µm, respectively. Preliminary in vivo skin imaging experiment results showed that the PCM device could visualize characteristic cellular features of human skin extending from the stratum corneum to the superficial dermis. Dynamic imaging of blood flow in vivo was also demonstrated. The capability to visualize cellular features up to the superficial dermis is expected to facilitate evaluation and clinical adoption of this low-cost diagnostic imaging tool.

RESUMO

Background: Current health behavior recommendations for skin cancer prevention, treatment, and survivorship are the same for survivors of other cancers; they include eating a healthy diet, being physically active, maintaining a healthy weight, and minimizing ultraviolet (U.V.) exposure. Few interventions exist to support health behaviors beyond U.V. exposure. We adapted Harvest for Health, a home-based mentored gardening intervention for cancer survivors, for implementation in Arizona as a community-based intervention. Methods: Stakeholder-informed adaptations for Harvest for Health Together Arizona (H4H2-AZ) included updating intervention materials to be relevant to the arid desert environment, emphasizing the importance of sun safety in cancer survivorship, and shifting from a home-based to a community-based delivery model. Participants will be enrolled in cohorts aligned with growing seasons (e.g., spring, monsoon, fall) and matched to an individual 30 ft2 community garden plot for two growing seasons (6 months). Original intervention components retained are: 1) Master Gardeners deliver the intervention providing one-to-one mentorship and 2) gardening materials and supplies provided. This pilot six-month single-arm intervention will determine feasibility, acceptability, and appropriateness of an evidence-based adapted mentored community gardening intervention for survivors of skin cancer as primary outcomes. Secondary outcomes are to explore the effects on cancer preventive health behaviors and health-related quality of life. Discussion: This pilot single-arm intervention will determine feasibility, acceptability, and appropriateness of an evidence-based adapted mentored community gardening intervention for survivors of skin cancer. If successful, the intervention could be widely implemented throughout existing Master Gardener programs and community garden networks for survivors of other cancers. Trial registration: ClinicalTrials.gov identifier: NCT05648604. Trial registered on December 13, 2022.

RESUMO

Background: IgA vasculitis in adults has not been thoroughly studied. This has left a practice gap related to the management and follow-up of a population that is at an increased risk of comorbidities and potentially poor outcomes. For this reason, it is important to synthesize evidence from the current literature because this can help direct the movement for more robust studies to clarify best practice recommendations. Objective: We sought to create a narrative review for the practicing dermatologist when diagnosing and leading the care of IgA vasculitis in adult patients. Methods: A broad literature search was performed with a focus on articles that were published after the introduction of the most updated European Alliance of Associations for Rheumatology/Pediatric Rheumatology International Trials Organization/Pediatric Rheumatology European Society criteria. Results: The characteristics and management guidelines for IgA vasculitis in adults have been refined, although more rigorous studies are needed to develop best practice recommendations. Limitations: Because of the lack of sufficient randomized controlled trials on IgA vasculitis in adults, this narrative review is composed of mostly observational, descriptive studies. Conclusion: Adults with IgA vasculitis are at an increased risk of complicated disease course, necessitating formal diagnostic assessment and clear-cut follow-up recommendations to manage and prevent poor health outcomes related to various comorbidities.

RESUMO

Generalised eruptive histiocytosis is a rare proliferative disease that typically presents with indolent cutaneous eruptions. We describe the case of a 73-year-old man presenting with diffuse, asymptomatic crops of pink to dusky red papules preceded by general malaise, myalgias, fluctuating fever, chills, and weight loss. Histological evaluation revealed a non-Langerhans cell histiocytic dermal infiltrate with spindle cell features and chronic inflammation, reactive for CD68 and negative for both S100 and CD1a. Malignancy screening was negative. This report aims to highlight a unique presentation of generalised eruptive histiocytosis, emphasise histological findings, and discuss considerations for malignancy screening.

RESUMO

BACKGROUND AND PURPOSE: Skin cancer, the most commonly diagnosed cancer in the United States, is a serious health care concern. Early skin cancer detection improves prognosis; most common early detection approach is a comprehensive clinical skin examination (CSE). A CSE consists of skin cancer risk assessment, head-to-toe skin examination, and skin lesion assessment. Nurse practitioners (NPs) currently lack adequate training and confidence to conduct CSE. The goal of this systematic review was to learn more about published interventions targeting CSE training for primary care NPs and/or other primary care providers. The findings were categorized based on the established procedures for intervention development. METHODS: The databases PubMed, Google Scholar, CINAHL, and Web of Science were searched. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, 10 articles were selected for data extraction. CONCLUSIONS: There is a paucity of articles that report rigorously developed interventions aimed at educating primary care NPs to conduct CSE. Existing CSE interventions were not tested for efficacy or effectiveness, and the implementation methods were weak or not reported. A synthesis of the review findings revealed inadequately reported sample characteristics, vague intervention goals, unspecified frequency or duration of interventions, and lack of standardized intervention protocols. IMPLICATIONS FOR PRACTICE: This review builds a foundation for more rigorously developed interventions to improve CSE and provides guidance for NPs to select education on CSE and other clinical foci. Future research will guide the development and evaluate the effectiveness of CSE education, which ultimately could improve skin cancer prognosis interventions and lack of standardized intervention protocols.
