RESUMO

A 29-year-old male patient had severe atopic dermatitis (AD) and alopecia universalis (AU) that could not be controlled by using classic therapy. He started taking upadacitinib and achieved an excellent response for both his AD and AU. Thus, upadacitinib represents a promising therapeutic approach for patients with severe AD and alopecia areata.

RESUMO

Hereditary angioedema (HAE) encompasses a group of diseases characterized by recurrent, genetically mediated angioedema associated with increased vascular permeability primarily due to bradykinin. The disease poses diagnostic challenges, leading to underdiagnosis and delayed therapy. Severe manifestations include laryngeal and intestinal angioedema, contributing to significant morbidity and mortality. If left undiagnosed, the estimated mortality rate of the disease ranges from 25% to 40% due to asphyxiation caused by laryngeal angioedema. There is a pressing need to enhance awareness of hereditary angioedema and its warning signs. The acronym "H4AE" may facilitate the memorization of these signs. This study comprehensively reviews clinical, laboratory, and physiopathological features of documented HAE subtypes. The study advocates for an improved HAE classification based on endotypes, building on the knowledge of angioedema pathophysiology. The proposed endotype classification of HAE offers a clear and applicable framework, encouraging advancements in disease understanding and classification.

RESUMO

A dermatite atópica (DA) e o prurigo nodular (PN) são doenças inflamatórias da pele que cursam com lesões variadas, como eczemas, pápulas e nódulos, acompanhados de intenso prurido e, nos casos graves, de importante prejuízo da qualidade de vida para os pacientes e seus familiares. O dupilumabe está aprovado no Brasil para o manejo das duas condições: DA moderada/grave e PN que não responde aos tratamentos tópicos. A eficácia e segurança do dupilumabe foram amplamente estabelecidas para ambas as condições em ensaios clínicos e estudos de vida real. Este artigo tem como objetivo revisar os principais eventos adversos (EAD) associados ao uso do dupilumabe em DA e PN, e auxiliar no seu manejo. Desde o início do uso da medicação, há alguns anos, os principais EAD reportados foram: a reação no local da injeção, a doença da superfície ocular (conjuntivite não infecciosa, blefarite, olhos secos), a eosinofilia e o eritema de face/pescoço. Outras manifestações também foram observadas em pacientes com DA em uso de dupilumabe, mas sem associação comprovada: psoríase, artralgia e alopecia areata. Apesar de muito infrequentemente levarem à suspensão do dupilumabe, é fundamental que os médicos prescritores deste medicamento para estas condições, dermatologistas e imunoalergistas, saibam detectar e manejar seus possíveis eventos adversos.

Atopic dermatitis (AD) and prurigo nodularis (PN) are inflammatory skin diseases characterized by various lesions such as eczema, papules, and nodules, with marked pruritus and, in severe cases, significant impairment of quality of life for patients and their families. Dupilumab is approved in Brazil for the management of both moderate/severe AD and PN that does not respond to topical treatments. The efficacy and safety of dupilumab have been extensively established for both conditions in clinical trials and real-world studies.This article aims to review the main adverse events (AEs) associated with the use of dupilumab in AD and PN and assist in their management. Since the introduction of dupilumab a few years ago, the main reported AEs have been injection site reactions, ocular surface disease (non-infectious conjunctivitis, blepharitis, dry eyes), eosinophilia, and facial/neck erythema. Other manifestations have also been observed in patients with AD on dupilumab, but without proven association: psoriasis, arthralgia, and alopecia areata. Although AEs very infrequently lead to discontinuation of dupilumab, it is crucial that physicians prescribing it for these conditions, dermatologists, and immunologists know how to detect and manage its possible adverse effects.

RESUMO

Background: The use of artificial intelligence (AI) in medicine has been a trending subject in the past few years. Although not frequently used in daily practice yet, it brings along many expectations, doubts, and fears for physicians. Surveys can be used to help understand this situation. Objective: This study aimed to explore the degree of knowledge, expectations, and fears on possible AI use by physicians in daily practice, according to sex and time since graduation. Methods: An electronic survey was sent to physicians of a large hospital in Brazil, from August to September 2022. Results: A total of 164 physicians responded to our survey. Overall, 54.3% (89/164) of physicians considered themselves to have an intermediate knowledge of AI, and 78.5% (128/163) believed that AI should be regulated by a governmental agency. If AI solutions were reliable, fast, and available, 77.9% (127/163) intended to frequently or always use AI for diagnosis (143/164, 87.2%), management (140/164, 85.4%), or exams interpretation (150/164, 91.5%), but their approvals for AI when used by other health professionals (85/163, 52.1%) or directly by patients (82/162, 50.6%) were not as high. The main benefit would be increasing the speed for diagnosis and management (106/163, 61.3%), and the worst issue would be to over rely on AI and lose medical skills (118/163, 72.4%). Physicians believed that AI would be useful (106/163, 65%), facilitate their work (140/153, 91.5%), not alter the number of appointments (80/162, 49.4%), not interfere in their financial gain (94/162, 58%), and not replace their jobs but be an additional source of information (104/162, 64.2%). In case of disagreement between AI and physicians, most (108/159, 67.9%) answered that a third opinion should be requested. Physicians with ≤10 years since graduation would adopt AI solutions more frequently than those with >20 years since graduation (P=.04), and female physicians were more receptive to other hospital staff using AI than male physicians (P=.008). Conclusions: Physicians were shown to have good expectations regarding the use of AI in medicine when they apply it themselves, but not when used by others. They also intend to use it, as long as it was approved by a regulatory agency. Although there was hope for a beneficial impact of AI on health care, it also brings specific concerns.

RESUMO

OBJECTIVE: The primary aim of this study was to understand the difference in the use of Telemedicine by Brazilian physicians before and after the onset of COVID-19 pandemic and their intention to continue using it post the pandemic period. The secondary objective was to analyze the differences of opinion between physicians in the private and public sectors. METHODS: We conducted an online medical survey through the SurveyMonkey platform in a large hospital in São Paulo, Brazil, from May to July 2022. RESULTS: Three-hundred-and -two physicians responded to the survey. We found that there was a significant increase in the number of physicians who started using Telemedicine in both the public and private sectors (p<0.0001) since the onset of COVID-19 pandemic and that >50% of them intend to continue using Telemedicine in their daily practice. Most responders consider that Telemedicine is useful in screening, diagnosis and management of patients; that it facilitates the physician's daily practice; that it can maintain or even add financial gains through reducing office expenses; and that is another medium for dispensing medical care. They also believe that Telemedicine should be regulated by the Brazilian Federal Council of Medicine. There were no significant differences between the responses from private and public sector physicians. CONCLUSION: Telemedicine has played a major role in healthcare since the onset of COVID-19 pandemic and most of the physicians approve its use and intend to continue using Telemedicine in their daily practice.

RESUMO

Introduction: The use of deep convolutional neural networks for analyzing skin lesion images has shown promising results. The identification of skin cancer by faster and less expensive means can lead to an early diagnosis, saving lives and avoiding treatment costs. However, to implement this technology in a clinical context, it is important for specialists to understand why a certain model makes a prediction; it must be explainable. Explainability techniques can be used to highlight the patterns of interest for a prediction. Methods: Our goal was to test five different techniques: Grad-CAM, Grad-CAM++, Score-CAM, Eigen-CAM, and LIME, to analyze the agreement rate between features highlighted by the visual explanation maps to 3 important clinical criteria for melanoma classification: asymmetry, border irregularity, and color heterogeneity (ABC rule) in 100 melanoma images. Two dermatologists scored the visual maps and the clinical images using a semi-quantitative scale, and the results were compared. They also ranked their preferable techniques. Results: We found that the techniques had different agreement rates and acceptance. In the overall analysis, Grad-CAM showed the best total+partial agreement rate (93.6%), followed by LIME (89.8%), Grad-CAM++ (88.0%), Eigen-CAM (86.4%), and Score-CAM (84.6%). Dermatologists ranked their favorite options: Grad-CAM and Grad-CAM++, followed by Score-CAM, LIME, and Eigen-CAM. Discussion: Saliency maps are one of the few methods that can be used for visual explanations. The evaluation of explainability with humans is ideal to assess the understanding and applicability of these methods. Our results demonstrated that there is a significant agreement between clinical features used by dermatologists to diagnose melanomas and visual explanation techniques, especially Grad-Cam.

RESUMO

Background: Skin cancer is one of the most common forms worldwide, with a significant increase in incidence over the last few decades. Early and accurate detection of this type of cancer can result in better prognoses and less invasive treatments for patients. With advances in Artificial Intelligence (AI), tools have emerged that can facilitate diagnosis and classify dermatological images, complementing traditional clinical assessments and being applicable where there is a shortage of specialists. Its adoption requires analysis of efficacy, safety, and ethical considerations, as well as considering the genetic and ethnic diversity of patients. Objective: The systematic review aims to examine research on the detection, classification, and assessment of skin cancer images in clinical settings. Methods: We conducted a systematic literature search on PubMed, Scopus, Embase, and Web of Science, encompassing studies published until April 4th, 2023. Study selection, data extraction, and critical appraisal were carried out by two independent reviewers. Results were subsequently presented through a narrative synthesis. Results: Through the search, 760 studies were identified in four databases, from which only 18 studies were selected, focusing on developing, implementing, and validating systems to detect, diagnose, and classify skin cancer in clinical settings. This review covers descriptive analysis, data scenarios, data processing and techniques, study results and perspectives, and physician diversity, accessibility, and participation. Conclusion: The application of artificial intelligence in dermatology has the potential to revolutionize early detection of skin cancer. However, it is imperative to validate and collaborate with healthcare professionals to ensure its clinical effectiveness and safety.
