RESUMO

Patient adherence to medications for common skin conditions has been extensively studied over the past two decades, and suboptimal adherence is a primary contributor to treatment failure. The impact of sub-par adherence in cutaneous T-cell lymphoma (CTCL) patients has been largely unexplored, and promoting adherence in this patient population may represent a promising area of consideration for improving treatment outcomes. We apply patient adherence strategies that have been studied in dermatology to CTCL and provide concrete examples of how these strategies can be used to improve adherence in the CTCL setting. Through the implementation of small changes in how we present and counsel about therapeutic options to our patients, we can maximize patient adherence, which has the potential to optimize therapy regimens and reduce treatment failure.

RESUMO

Optical coherence tomography (OCT) suffers from speckle noise due to the high spatial coherence of the utilized light source, leading to significant reductions in image quality and diagnostic capabilities. In the past, angular compounding techniques have been applied to suppress speckle noise. However, existing image registration methods usually guarantee pure angular compounding only within a relatively small field of view in the focal region, but produce spatial averaging in the other regions, resulting in resolution loss and image blur. This work develops an image registration model to correctly localize the real-space location of every pixel in an OCT image, for all depths. The registered images captured at different angles are fused into a speckle-reduced composite image. Digital focusing, based on the convolution of the complex OCT images and the conjugate of the point spread function (PSF), is studied to further enhance lateral resolution and contrast. As demonstrated by experiments, angular compounding with our improved image registration techniques and digital focusing, can effectively suppress speckle noise, enhance resolution and contrast, and reveal fine structures in ex-vivo imaged tissue.

RESUMO

The pathogenesis of psoriasis may involve a breakdown of immune tolerance to cutaneous microorganisms. Psoriasis is associated with a higher incidence of Crohn disease and periodontitis, two diseases involving impaired tolerance and abnormal immune activation in response to intestinal and oral microbiota, respectively. In addition, guttate and chronic plaque psoriasis are associated with Streptococcus pyogenes colonization. The aim of this review is to characterize the microorganisms implicated in psoriasis by examining results of major association studies and possible mechanisms of pathogenesis. Although studies show relative increases in Streptococcus and Staphylococcus and decreases in Malassezia and Cutibacterium, they differ in methods of sampling and methods of microbial analysis. As such, no definitive associations between microbes and psoriasis have been found to date. It also remains unclear if changes in the microbiomal composition have a causal association with psoriasis or are simply a consequence of the inflammatory microenvironment. Techniques enabling strain-level analysis rather than species-level analysis of the skin microbiome are likely necessary to determine microbiomal signatures of psoriasis. Future investigations may lead to new diagnostic tests and novel treatments, such as probiotics or bacterial transplantation.

RESUMO

BACKGROUND: The field of transplantation is shifting outcome priorities from 1-year survival to more comprehensive metrics including transplant rate and waitlist mortality. Identifying disenfranchised candidates (high waitlist death risk, low transplantation chance) can be a focus to improve outcomes. METHODS: Given the waitlist outcomes (continued waiting, death, and transplantation), we aimed to identify factors predicting the likelihood candidates would undergo transplant or death by performing multivariate competing risk analyses of 121 198 candidates in the United Network for Organ Sharing database. We incorporated these probabilities (likelihood of transplantation and waitlist death) into the Transplant Index (TI) to identify disenfranchised candidates (high likelihood of death, low likelihood of transplantation). RESULTS: Half of the patients had low incidences of death and transplantation within 90 days (TI-inactive). The remaining were stratified into 10 groups within a predictive index, the TI. Low TI groups (TI 10, 20, 30) had 90-day transplant rates of 50.8%, 41.6%, and 39.8% respectively, and their respective 90-day death rates were 22.8%, 15.1%, and 10.9%. High TI groups (TI 80, 90, >90) had 90-day transplantation rates of 53.7%, 64.3%, and 73.9%, respectively, and 90-day death rates of 5.9%, 6.5%, and 6.7% respectively. As TI increased, the likelihood of transplantation increased and that of death decreased. Low-TI groups represent the disenfranchised candidates. CONCLUSIONS: The TI identifies disenfranchised candidates on the adult liver transplant waitlist. This is the subgroup that would benefit the most from efforts to increase access to transplantation.

RESUMO

Generalized morphea is associated with epoxy resin vapors and is characterized by the development of lesions shortly after exposure. Morphea presenting along with eosinophilic fasciitis (EF), or morphea/EF overlap, is rare and an indicator of poor prognosis and resistance to treatment. Here we present a case of generalized morphea/EF overlap linked to epoxy exposure. Our patient received multiple therapies-ultraviolet A1 phototherapy, prednisone, methotrexate, azathioprine, mycophenolate mofetil, cyclophosphamide, cyclosporine, and rituximab-none of which led to a significant response. The refractory nature of this disease warrants vigilance in its association with epoxy exposure.

RESUMO

Numerous clinicopathological variants of mycosis fungoides have been described in the literature. Dermatomal or zosteriform mycosis fungoides is one reported variant but a clear aetiology has never been documented. We report a case of mycosis fungoides proved by biopsy and immunohistochemistry that developed in a 55-year-old man at the site of previous herpes zoster eruption. We also present a review of the relevant literature to add to the understanding of rare variants of mycosis fungoides and aid in the clinical recognition of zosteriform mycosis fungoides.

RESUMO

Mycosis fungoides with large-cell transformation is historically associated with a poor prognosis. Pediatric cases of mycosis fungoides with large-cell transformation are rare, with only three other cases reported in the literature. We present the first case of a child with almost complete remission of his mycosis fungoides with large-cell transformation shortly after administration of psoralen plus ultraviolet A, interferon-alfa, and localized radiation.
