ABSTRACT
Background: The Infants and Toddlers Dermatology Quality of Life (InToDermQoL) questionnaire is the first dermatology-specific proxy health related QoL instrument for children from birth to 4 years. Score meaning bands and the sensitivity to successful therapeutic intervention are important to interpret the clinical meaning of an instrument. Objective: The aim of the present study was to check the sensitivity to successful therapeutic intervention and establish score bands of the InToDermQoL questionnaire. Methods: Parents or grandparents of 424 children with skin diseases from Spain, Malta, Croatia, Romania, Greece, and Ukraine filled in national language versions of the InToDermQoL questionnaire. Disease severity of children with atopic dermatitis was assessed by SCORAD (Scoring atopic dermatitis). Cohen's d was used to assess the responsiveness of the instrument. Results: The mean total InToDermQoL scores significantly decreased after treatment. Severity grading of the SCORAD scores gave stratification of the InToDermQoL severity grades based on 95% confidence intervals. Scores below a calculated minimal important difference of 2 corresponded to no effect on patient's health related QoL. Limitations: Score banding may be slightly different across patient population and study context. Conclusion: All 3 age-specific versions of the InToDermQoL questionnaire showed sensitivity to treatment. Score bands for the InToDermQoL questionnaire have been established.
ABSTRACT
INTRODUCTION: Reddit, a popular social media website, has numerous forums where users may discuss healthcare-related topics and request diagnostic and treatment advice for dermatologic conditions. We sought to analyze and grade user-submitted requests for dermatologic advice and their top responses on Reddit. METHODS: User-submitted posts requesting diagnostic advice and their respective responses on two popular Reddit forums, SkinCareAddiction (ScA) and DermatologyQuestions (DQ), were reviewed by three board-certified dermatologists using a grading rubric designed for this study. RESULTS: 300 posts and comments were reviewed. Diagnoses among all graders matched in 52.3% of posts with a mean grader confidence score of 4/5 (95% CI 3.89-4.11). 31% of responder's comments recommended a diagnosis not included by any reviewer. Mean scores for the top comment's accuracy, appropriateness, and potential to be misleading/dangerous were 3.28/5 (95% CI 3.12-3.45), 3.3/5 (95% CI 3.14-3.45), and 2.33/5 (95% CI 2.18-2.48), respectively. CONCLUSION: Reddit may be informative to patients requesting dermatologic advice. However, responses should be taken with caution as the information provided may be inaccurate or insufficient for treatment recommendations. Dermatologists should be aware of these resources used by patients.
ABSTRACT
Background: In the aftermath of the COVID-19 pandemic, medical students and residents in the U.S. and globally have gained more exposure to teledermatology, both for the purposes of clinical practice and education. Objective: We conducted a systematic review to assess outcomes from teledermatology interventions for dermatology trainees in the U.S. and globally in accordance with Preferred Reporting Items for Systematic Reviews (PRISMA). Methods: We searched MEDLINE, EMBASE, Web of Science, and Cochrane CENTRAL for articles written in English and published database inception to November 20, 2022. Results: In total, 15 studies met the inclusion criteria. Outcomes reported ranged broadly from resident-provider concordance rates, diagnostic accuracy in comparison to control groups, number of patients seen, and self-reported satisfaction and improvement. Generally, studies indicated high satisfaction rates and improvement in educational outcomes among medical students, residents, and other trainees in the global health setting. Limitations: Because of the heterogeneity of study design and outcomes reported, meta-analysis could not be performed. Conclusion: Teledermatology can be successfully deployed for clinical care and education domestically and in the global health setting.
ABSTRACT
BACKGROUND: COVID-19 is a highly contagious respiratory tract infection caused by severe acute respiratory syndrome coronavirus 2. COVID-19 outbreak, which caused thousands of deaths, has been declared a pandemic by the World Health Organization in March 2020. AIM: Skin manifestations related to SARS-CoV-2 infection can be divided mainly into five groups: chilblainlike lesions (CBLLs), maculopapular eruptions, urticarial eruptions, vesicular eruptions, and livedo or necrosis. Other skin findings reported are erythema multiforme (EM)-like lesions and skin findings associated with multisystem inflammatory syndrome in children (MIS-C) and rarely with multisystem inflammatory syndrome in adults (MIS-A). Other manifestations such as pityriasis rosea or shingles are also reported. METHODS: A total of 60 articles including reviews, studies and case reports were selected for the evaluation in this review. RESULTS: The skin manifestations associated with COVID-19 infection are numerous and can vary widely. The major dermatological patterns of COVID-19 can be classified as inflammatory reactions (maculopapular/morbilliform, urticarial and vesicular rashes), or lesions of vascular origin (chilblain like rashes, petechiae/purpura, and livedo acemose-like pattern) CONCLUSION: We believe that the dermatologist could play an important role in the response to the SARS-CoV-2 pandemic through early recognition of skin lesions suggestive of COVID-19, particularly in paucisymptomatic infections where this recognition could direct toward an early diagnosis of infection that certainly leads to a better prognosis.
ABSTRACT
INTRODUCTION: Artificial intelligence (AI) has an important role to play in future healthcare offerings. Machine learning and artificial neural networks are subsets of AI that refer to the incorporation of human intelligence into computers to think and behave like humans. OBJECTIVE: The objective of this review article is to discuss perspectives on the AI in relation to Coronavirus disease (COVID-19). METHODS: Google Scholar and PubMed databases were searched to retrieve articles related to COVID-19 and AI. The current evidence is analysed and perspectives on the usefulness of AI in COVID-19 is discussed. RESULTS: The coronavirus pandemic has rendered the entire world immobile, crashing economies, industries, and health care. Telemedicine or tele-dermatology for dermatologists has become one of the most common solutions to tackle this crisis while adhering to social distancing for consultations. While it has not yet achieved its full potential, AI is being used to combat coronavirus disease on multiple fronts. AI has made its impact in predicting disease onset by issuing early warnings and alerts, monitoring, forecasting the spread of disease and supporting therapy. In addition, AI has helped us to build a model of a virtual protein structure and has played a role in teaching as well as social control. CONCLUSION: Full potential of AI is yet to be realized. Expert data collection, analysis, and implementation are needed to improve this advancement.
ABSTRACT
Dermoscopic images ideally depict pigmentation attributes on the skin surface which is highly regarded in the medical community for detection of skin abnormality, disease or even cancer. The identification of such abnormality, however, requires trained eyes and accurate detection necessitates the process being time-intensive. As such, computerized detection schemes have become quite an essential, especially schemes which adopt deep learning tactics. In this paper, a convolutional deep neural network, S2C-DeLeNet, is proposed, which (i) Performs segmentation procedure of lesion based regions with respect to the unaffected skin tissue from dermoscopic images using a segmentation sub-network, (ii) Classifies each image based on its medical condition type utilizing transferred parameters from the inherent segmentation sub-network. The architecture of the segmentation sub-network contains EfficientNet-B4 backbone in place of the encoder and the classification sub-network bears a 'Classification Feature Extraction' system which pulls trained segmentation feature maps towards lesion prediction. Inside the classification architecture, there have been designed, (i) A 'Feature Coalescing Module' in order to trail and mix each dimensional feature from both encoder and decoder, (ii) A '3D-Layer Residuals' block to create a parallel pathway of low-dimensional features with high variance for better classification. After fine-tuning on a publicly accessible dataset, a mean dice-score of 0.9494 during segmentation is procured which beats existing segmentation strategies and a mean accuracy of 0.9103 is obtained for classification which outperforms conventional and noted classifiers. Additionally, the already fine-tuned network demonstrates highly satisfactory results on other skin cancer segmentation datasets while cross-inference. Extensive experimentation is done to prove the efficacy of the network for not only dermoscopic images but also different medical modalities; which can show its potential in being a systematic diagnostic solution in the field of dermatology and possibly more.
ABSTRACT
Telemedicine was accelerated in adoption in low to middle-income countries because of the COVID-19 pandemic. Institutions and societies new to this modality released recommendations that extrapolate from Western practices or more developed regions of Asia. Besides cultural differences, many areas do not have similar staffing set up as in the West. Many doctors provide direct to patient telemedicine. Framing telemedicine as part of hybrid care instead of a competitor to in-person care may be key for telemedicine to secure its place in healthcare. We would need to examine workflows that may help us in this endeavor. Infographics is short for information graphics. They are digital tools used to enhance education, improve memory, and comprehension, and develop new communication skills. In pandemic remote care studies, surgeons use infographics to teach patients post op wound care at home. How about medical photography? Medical photography has been used as a prehospital assessment for ER cases. In some dermatology studies, photos are used as a form of triage to avoid unnecessary in-person consults. Orthopedic surgeons use photography to assess post op range of motion. One psoriatic arthritis study incorporated photography as a pre-visit screening with staff members assisting patients. With the advances in personal smartphone technology, is there a role for patients or caregivers themselves to use medical photography in telemedicine? Since many clinics may not have adequate staff members, a simple instruction guide on lighting, framing and technique could be used for patients to take their own photos and then send it to their doctors prior to their telemedicine visit. We take a look at the studies on medical photography and the possibility of incorporating it to our own telemedicine workflow. In addition, we would present out proposal for a mixed method study using a simplified infographic for patients to copy pre-visit.
ABSTRACT
Medical image analysis based on computer vision technology has always been a research hotspot in the community, which aims to assist doctors in diagnosis by accurately analyzing pathological images to divide the patient's condition and the patient's lesions. Thanks to the rapid development of deep learning, the application of computer image recognition technology in medicine is becoming more and more widespread, while still facing a series of challenges such as low data set data, insufficient performance of algorithms and fine delineation of lesions. In order to solve these problems, based on extensive literature research, this paper first compares the algorithms in the application for Corona Virus Disease 2019, skin cancer and liver cancer. Then we introduce the improvement of these algorithms by expanding the number of data sets, optimizing the algorithms, and fitting the neural networks and models, whcih can improve the accuracy of image recognition technology to assist doctors in identifying lesions in clinical practice. The algorithms are further compared quantitatively on the basis of the training set in clinical diseases, and the difficulties to be overcome in image recognition and the future development trend are explained and predicted from the analysis of the comparison. Many new algorithms and excellent models are being gradually improved with the development of the times, and image recognition technology will also develop towards more research fields in the future. © 2023 SPIE.
ABSTRACT
Background: COVID-19 is significantly impacting healthcare delivery worldwide. Chen et al anecdotally reported the impact on dermatology outpatient care at the outbreak epicenter in Wuhan, China, but nothing has yet been assessed for the US. The purpose of this study was to determine the magnitude of the ongoing impact of COVID-19 on US dermatology outpatient care. Methods: After pre-validation, 2 surveys comparing outpatient volumes and scheduling issues for the weeks of February 17th versus the week of March 16th, 2020 (Survey 1) and April 13th, 2020 (Survey 2) and for estimation of trends in the next several weeks was emailed to 9,891 US Dermatologists on 3/21(Survey 1) and 4/18(Survey 2)(Tables S1a & S1b). Because of the importance of this information and the need for rapid dissemination, only data from the first 1,000 respondents (collected in the initial 36 hours) were included in each survey. In Survey 1, 30 responses were removed due to ineligible geography or errors in survey entry, leaving 970 for the analysis. Survey 2 consisted of 1,000 eligible respondents. Demographics (Table 1) representativeness with AAD membership was confirmed (Table S2). Statistical significance was calculated using chi-square, difference-of-proportions, and two-tailed independent t-tests. Results: COVID-19 impact was material (Table 2). From the 3rd week in February to the 3rd week in March to the 3rd week in April, the average number of patients seen fell from 149.4 to 63.4 to 28.2(p<0.0001), practice days from 4.2 to 3.1 and then rose to 3.5(p<0.0001) and biopsies from 19.8 to 7.7 to 3.5(p<0.0001). Although by 3/16 there were only 24.5k cases nationally, the early-phase decrease in patient volume and office days suggests the magnitude of disease concern impact was greater than actual prevalence. Postponement of non-essential appointments increased from 35.5% to 79.4% to 95.6%(p<0.00001). In Survey 1, 66.3% of respondents estimated a >50% decrease in patient volume in the coming 2 weeks (18.9% completely closing practices) and, disturbingly, 47.2% of respondents in the 2nd survey estimated an additional 50%+ decrease in patient volume in the next 2 weeks. 54.6% (Survey 1) of postponed appointments were for >4 weeks with an additional 25.4% not rescheduled. Discussion: A greater negative impact was found in US "hotspot” regions (36% (Survey 1) and 34% (Survey 2) of respondents-Figure S1) for week 3/16-20 for practice days (3.0 hotspots vs. 3.3 non-hotspots) and patients seen (56.2 in hotspots vs. 70.0 in non-hotspots);and for week 4/13-18 (3.4 in hotspots vs 3.5 in non-hotspots) and patients seen (25.3 in hotspots vs 29.7 in non-hotspots). No significant differing telemedicine usage (39.5% hotspots vs 37.2% non-hotspots) or practice closure (21.0% hotspots vs 17.6% non-hotspots) was found in Survey 1 (March);however, a significant difference in telemedicine usage (54.5% hotspots vs 45.5% non-hotspots) and practice closure (25.4% hotspots vs 16.4% non-hotspots, when compared to a typical April week) was found in Survey 2 (April). Mean estimated telemedicine visits overall for the next 2 weeks was 37.8% (Survey 1) and 45.9% (Survey 2). Academic/University/Institutional dermatologists were significantly more likely to use telemedicine (Survey 1=57.1%, Survey 2=68.6%) than private practitioners (Survey 1=35.5%, Survey 2=46.2%). Telemedicine usage was less likely for dermatologists with >30 practice years (>30=32.4% vs 40.0%) and this trend continued in April with only 37.2% of more experienced dermatologists using telemendine. However, telemedicine usage does not have an impact on the deferred/postponed biopsies that had already occurred during the March (mean=10.7) or April (mean=7.9) weeks as well as those predicted to be subsequently postponed. Limitations include that this study reflects a "snapshot” which could materially change given the dynamically evolving situation. Estimations could have led to recall bias and the 10.1% response rate could have introduced sampling and non-response bias. Those with lower work volu es could have been more likely to have time to respond, but this bias was minimized by weekend-only data collection. However, the large sample size and representative distribution mitigate selection bias and standard statistical testing demonstrated significance.Conclusion: Our findings demonstrate the significant early impact of COVID-19 on US dermatologic care and can help better understand national trends. With an estimated 49.9 million annual US dermatology office visits, the 50%+ decrease in predicted visits could be devastating. Beyond telemedicine, other innovative approaches will need to be developed and implemented to help delivery of essential dermatology care during this crisis. © 2020, National Society for Cutaneous Medicine.

ABSTRACT
The COVID-19 pandemic created a unique challenge to health care systems, requiring rapid implementation of telemedicine services to provide continued care to patients while preserving personal protective equipment and decreasing the risk of disease transmission. Herein, we describe how our institution, an urban cancer center, utilized provider-to-provider telemedicine consultations (interprofessional e-consults) to provide subspecialty access to care to vulnerable patients in the epicenter of a global pandemic.
ABSTRACT
BACKGROUND: The COVID-19 pandemic has had dramatic effects on all fields of medicine, including an effort to limit in-person visits. Within dermatologic surgery, one strategy is to close surgical incisions using percutaneous absorbable sutures. To the authors' knowledge, there are no large studies comparing changes in suture preferences and subsequent outcomes during the pandemic. OBJECTIVE: To assess changes in suture preference and frequency of post-operative complications for percutaneous absorbable and non-absorbable sutures during the pandemic. METHODS: A retrospective review of 1358 Mohs surgeries completed at the Cleveland Clinic during a 2-month period prior to COVID-19 and a matched 2-month period during the pandemic. RESULTS: Sutures were used to close 1103 cases. Significantly more closures were performed with percutaneous absorbable sutures during COVID-19 (87.6%, 39.6%; P < .0001). There was no significant difference in the frequency of post-operative complications between suture materials (P = .48). The use of absorbable sutures were associated with a significantly higher frequency of suture hypersensitivity reaction (P = .020) but significantly lower frequency of infection (P = .021) and wound dehiscence (P < .0001). CONCLUSIONS: Suture preference shifted towards absorbable sutures during the COVID-19 pandemic. Percutaneous absorbable sutures offered a formidable alternative to non-absorbable sutures and could reduce in-person follow-up visits without increasing post-operative complications.
ABSTRACT
As the world has not fully recovered from the aftermath of COVID-19, a new pandemic appears on the horizon. Monkey Pox is emerging as a new threat to the health of the world population. With the recorded spread over 40 countries worldwide it might be soon declared a pandemic. Monkey Pox shares common features with chickenpox and measles making it difficult to diagnose. Developing a new test kit at this early stage is a challenging task for the medical fraternity. This paper proposes the use of deep learning models that can be used to make the process of diagnosis automated. This paper tries to come up with a performance comparison of ResNet50, EfficientNetB3 and EfficientNetB7 algorithms. This study suggests a method for early detection of Monkey Pox Skin Lesion. Though an extensive study with other models on a larger dataset containing more images from various countries of the world needs to be carried out but this study gives some promising results on this limited dataset. © 2022 IEEE.
ABSTRACT
Introduction/Background: Antiphospholipid syndrome (APS) is a rare autoimmune multisystem disease characterised by thrombosis and pregnancy morbidity in the presence of persistently elevated titres of: lupus anticoagulant, anticardiolipin and/or anti-glycoprotein 1. It may be primary (occurring alone) or secondary (in combination with another disease, most commonly systemic lupus erythematosus (SLE)). Recent publications highlighted clinical criteria limitations for children and raised awareness of the burden and prevalence of non-criteria manifestations in this population. This case report adds further weight to the need to raise multi-specialty awareness of non-criteria manifestations to aid recognition and treatment of this rare condition with potentially severe sequelae. Description/Method: 13-year-old female with SLE diagnosed aged 8 in India with bilateral optic neuritis occurring two months later. ANA positive at diagnosis with low complement and thrombocytopenia. Treated with prednisolone and hydroxychloroquine. Patient moved to the UK aged 9;initial abnormal bloods: mildly positive ANA (ENA negative), thrombocytopenia, strong lupus anticoagulant. As serology not strongly suggestive and optic neuritis rare in lupus diagnosis questioned. Ophthalmology review confirmed bilateral optic atrophy without evidence of previous vasculitis. There was debate whether the postretinal demyelination was due to antiphospholipid syndrome or a primary demyelinating condition. Hydroxychloroquine stopped and azathioprine started. Following normal neurology investigations (brain, spine MRI/MRV/MRA) concluded if patient developed new APSrelated symptoms or worsening visual evoked potentials anticoagulation would be discussed. Patient remained stable over four years with chronic thrombocytopenia and ESR persistently elevated. Azathioprine changed to Mycophenolate mofetil (MMF) due to side effects. Routine medication monitoring bloods in 2022 showed ESR 97, CRP 78, Platelets 61. Review identified vasculitic rash on soles of both feet with palpable nodules and normal pulses. Further investigation confirmed antiphospholipid antibody triple positivity. Aspirin commenced, hydroxychloroquine restarted, MMF dose increased and rituximab administered. Left foot rash settled but right progressed with toe discolouration and numbness. Skin biopsy considered but not performed due to skin integrity concerns. Foot pulses remained present and normal. Bilateral lower limb doppler reported as normal;increased symptoms resulted in CT angiogram which revealed bilateral non-occlusive popliteal thrombus and left pulmonary embolus. Subsequent echocardiogram was normal. Patient was anticoagulated with low molecular weight heparin followed by warfarin. Vascular surgical team advocated medical management and patient received seven infusions of Iloprost followed by Sildenafil. She achieved near total resolution of skin changes to toes with only minimal loss of skin over tip of right great toe. Patient will now require long-termanticoagulation. Discussion/Results: APS was considered in initial differential diagnosis but patient did not meet current clinical criteria as no past evidence of thrombosis. Lupus anticoagulant was consistently strongly positive and anticardiolipin repeatedly negative. As anti-B2 glycoprotein 1 antibody is not routinely tested and must be verbally requested, it was only checked once (negative) prior to discovery of triple positivity. ANA reported as strongly positive at time of SLE diagnosis but reviewing original notes from India titre was 1:100 and therefore not highly convincing. ENA negative and complement and white cell count normal on repeat testing since. Therefore, it is probable that this patient has primary APS as opposed to secondary APS in association with SLE. However, it is possible that this patient may develop more symptoms of SLE over time. When this patient presented with foot rash there were high numbers of children presenting with varying severity of painful, itchy toes coined 'covid toes' due to suspected lin to SARS-CoV-2 infection. Patient had exposure history, and COVID antibody serology was difficult to interpret due to recent vaccination. Dermatology found appearance to be consistent with 'covid toes' and advised supportive treatment. The triple APS antibody positivity result provided probable aetiology. Providing evidence of thrombus was problematic with false reassurance from apparently normal lower limb arterial doppler when actually popliteal arteries were not checked in view of the presence of normal flow proximally at the groin and distally in the feet. This case highlights the need to continue to search for thrombus in presence of high titres antiphospholipid antibodies and particularly in the case of triple positivity as although patient presented with colour change to toes, she was entirely asymptomatic from her PE and her left foot improved spontaneously despite a left popliteal thrombus also being present. Key learning points/Conclusion: Non-criteria manifestation of thrombocytopenia (occurs in 25% paediatric APS patients) was present throughout and patient had past history of haematuria (a recognised renal non-criteria manifestation). A paediatric specific APS criteria including these may have resulted in earlier detection of triple antiphospholipid antibody positivity and thus earlier treatment escalation and possible avoidance of thrombus. It has been reported that a high proportion of children with positive antiphospholipid antibodies don't develop a thrombus. However, it is interesting that our patient was entirely asymptomatic from her pulmonary embolus which was an incidental finding on her CT angiogram. This prompts a discussion about how much imaging should be performed in those with high levels of persistent positive antiphospholipid antibodies. Rituximab resulted in normalisation of platelet count and ESR for the first time since initial presentation. Anticardiolipin antibodies normalised, lupus anticoagulant decreased from strong to moderate and anti- B2 glycoprotein levels decreased but remained positive. Rituximab is a recognised treatment for catastrophic antiphospholipid syndrome (CAPS) but not routinely used in APS. The consistently raised ESR in an apparently clinically well patient is a reminder to continue to search for causes of inflammation. As the CRP was largely in normal range, this demonstrates the unique value of the ESR. In view of anti-B2 glycoprotein 1 antibody requiring to be verbally requested, discussions are ongoing with the laboratory department regarding the possibility of electronic request and a comment with recommendation to check other two antiphospholipid antibodies following one positive antibody result. As a result of this case, a plan will be put in place to ensure annual screening of antiphospholipid antibodies in all juvenile SLE patients in our care. It is hoped that this case report promotes discussion amongst the paediatric rheumatology community regarding further research required for development of paediatric specific APS criteria and management.
ABSTRACT
The advent of vaccines represented a milestone to allow the slowing down and then containing of the exponential increase in ongoing infections and deaths of COVID-19. Since the first months of the vaccination campaign in various continents, there has been a certain number of reports of adverse events, including skin reactions. We conducted a systematic review, searching on PubMed, Web of Science, Scopus, and Cochrane Library for the words: COVID vaccine, dermatopathology, skin, eruptions, rash, cutaneous, BNT162b2 (Pfizer-BioNTech), ChAdOX1 (AstraZeneca), and mRNA-1273 (Moderna). A total of 28 records were initially identified in the literature search of which two were duplicates. After screening for eligibility and inclusion criteria, 18 publications were ultimately included. Various clinical cutaneous manifestations and histopathological patterns following vaccination have been described in literature. The most frequent clinical-pathological presentations were erythematous maculo-papular eruptions in different way of distribution with histopathological pictures mostly represented by interface changes and mixed peri-vascular and peri-adnexal cell infiltrate. Other presentations included new onset of pemphigoid bullous disease (n = 15), delayed T-cell-mediated hypersensitivity reaction (injection site reactions) (n = 10), purpuric skin rash (n = 13), mostly localized on the legs bilaterally and symmetrically with histological pictures characterized by extravasation of erythrocytes in the superficial and middle dermis, and other types of reactions. New studies with large case series and further literature reviews are needed to improve the clinical management of patients and optimize the timeline for carrying out histological biopsy for confirmatory, supportive, and differential diagnosis purposes.
ABSTRACT
Erythema nodosum (EN) is a common panniculitis characterized by tender erythematous nodules predominantly on the pretibial area and represents a hypersensitivity reaction to multiple triggers. COVID19 infection and vaccination have been associated with EN in the adult population. We report a pediatric case of EN following COVID19 infection and review the literature on COVID19 infection and COVID19 immunization-related EN.
