Response: Financial incentives have the potential to drive provider behavior, even unintentionally. The aim of this study was to evaluate differences in clinic “productivity” measures that occur in outpatient dermatology encounters. Specifically, we used data from 2016-2020 at one academic dermatology practice to evaluate differences in work relative value units (wRVUs, a measure of clinical productivity) and financial reimbursement by patient race, sex, and age. 66,463 encounters were included in this study, among which 70.1% of encounters were for white patients, 59.6% were for females, and the mean age was 55.9 years old.

MedicalResearch.com Interview with: [caption id="attachment_56598" align="alignleft" width="200"]Jill Sommerville M.Sc Director of Medical at WaterWipes Jill Sommerville[/caption] Jill Sommerville M.Sc Director of Medical at WaterWipes MedicalResearch.com: What is the background for this study? How prevalent is diaper dermatitis? Is it more severe in some babies? Response: The Utah study is an independent clinical study conducted by the University of Utah Hospital NICU, Salt Lake City and recently published in Advances in Neonatal Care journal. It was a year-long study conducted between January 2018 – March 2019. The NICU staff were interested in exploring a new Perineal Skin Care Guideline in their unit, encompassing use of WaterWipes, to decrease the incidence of diaper dermatitis. Their stated aim was to reduce diaper dermatitis by 20% within a 1-year period.  The study involved 1,070 premature babies, 11% of which were born at less than 30 weeks of gestational age. The inclusion criteria for the study were all babies who stayed for more than 1 day in the NICU. Diaper dermatitis is known to cause discomfort and emotional distress in all babies and can be a possible source of infection among NICU babies.  Diaper dermatitis remains prevalent, especially in preterm babies. The reported incidence varies from 21% to 25% among newborn intensive care babies. 1 Diaper dermatitis in pre term babies can be multifactorial especially as babies born early have a less well developed stratum corneum, the outer most layer of skin. NICU babies are often exposed to antibiotics and fortified milk to help them catch up growth. Other medical complications in addition can lead to altered gut flora and altered stool composition resulting in more frequency of stool. The presence of urine and frequent stools necessitates regular cleaning which can result in excessive rubbing of the skin or the use of wipes containing harsh ingredients that can damage the skin.

DermNZ[/caption] MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by actinic keratoses? How common are they and who is primarily affected? Response: Actinic keratosis is a very common precancerous skin condition that affects about 58 millions people in the US. Most commonly affected people are older (over 40 years old) men with fair skin type. Actinic keratosis lesions are red scaly bumps on sun-damaged skin mostly on the face, scalp, back of hands, forearms and legs. As there is a risk of 0.025-16% per year for each actinic keratosis to progress to skin cancer and it is not possible to predict which actinic keratosis will become cancerous, early treatment of actinic keratosis is generally recommended. Currently approved topical treatments require weeks or months of application and may lead to intolerable side effects that undermine compliance and reduce efficacy of treatment. Tirbanibulin ointment is a novel anti-proliferative agent that inhibits tubulin polymerization and disrupts Src kinase signaling, and has the potential to inhibit growth of abnormal skin cells in actinic keratosis. The current report described two Phase 3 randomized vehicle or placebo-controlled clinical studies that demonstrated that a 5-day course of tirbanibulin ointment applied once daily by patients was safe, well-tolerated, and effective in clearing actinic keratosis on the face or scalp compared to vehicle control.

Milliken Department of Internal Medicine Washington University in St. Louis MedicalResearch.com: What is the background for this study? Response: Patients with eczema suffer from chronic itch due to the rashes they have on their body. However, as a physician, I have always noticed that patients with eczema will have sudden flares of their itching all over there body that is often triggered by what appear to be allergens – being around a cat, pollen, mold in a house, etc. Eczema is in the family of allergic diseases such as food allergy, asthma, and hay fever. All of these conditions are noted for patients being reactive to allergens by way of an antibody called IgE that coats a cell called the mast cell. Upon IgE binding an allergen, mast cells produce tons of histamine which can cause symptoms like itching. So we speculated that perhaps because patients with eczema have such misbehaving IgE, that exposure to allergen is what triggers this kind of severe itch flare that we see in patients.

MedicalResearch.com Interview with: Karan Lal, DO, Marketing Committee Member for the Society for Pediatric Dermatology, Dermatologist at UMass Memorial Medical Center. Dr. Lal discusses the recent study of a procedure to remove black dye from henna tattoos. MedicalResearch.com: What is the background for this study? Response: Para‐phenylenediamine, a dye frequently added to henna tattoos to create the black color, is a potent contact allergen. Severe contact dermatitis may arise within days even after the first application. Our objective was to develop a method for rapid and complete removal of para‐phenylenediamine‐containing black henna tattoos from the skin, an important problem many physicians are confronted with, but for which no simple method exists.

Yet, little is known about recent trends in North America with respect to the clinical presentation and allergen profile in chronic hand eczema. This study sought to determine the clinical characteristics and etiologies of hand eczema in a large North American cohort of adults referred for patch testing. The patients in the study were patch tested using the North American Contact Dermatitis Group’s allergen screening series.

Response: Given concern in the public about exposure to nanoparticles in cosmetics, we decided to investigate the exposure potential for inhaling nanoparticles during the application of aerosol mineral-based sunscreens that are typically marketed as safer for children. We choose three commercially available sunscreens to test in the lab in a manner intended to capture the amount of inhaled particles that would typically occur during application of sunscreen to the mid-point of one’s own arm.

Rork, MD Assistant Professor of Dermatology Dartmouth-Hitchcock Medical Center at Manchester and The Geisel School of Medicine Society for Pediatric Dermatology Member MedicalResearch.com: What is the background for this study? Would you briefly explain the genetic condition of Down syndrome? Response:  Down syndrome is the most common chromosomal abnormality, occurring in approximately 1 in 700 newborns in the United States.  Trisomy of chromosome 21 can result in multisystem involvement such as hearing loss, heart defects, autoimmune conditions and dementia. This study focuses on how trisomy 21 affects one of the body’s largest organs, the skin. Current literature addressing dermatologic conditions associated with Down syndrome is limited. There is often emphasis on rare skin conditions such as elastosis perforans serpiginosa, milia-like idiopathic calcinosis cutis, and eruptive syringomas. There is lack of consensus on incidence of more common disorders. We performed a retrospective chart review of 101 patients with Down syndrome in our dermatology practice at the University of Massachusetts to better describe associated skin conditions.

Response: As a dermatopathologist who makes diagnoses on lesions that may be melanoma, I’m faced with the reality that my accurate interpretation of biopsy tissue is key for the patient to be treated most effectively. Often histopathological evaluation is straightforward but not as often as I would like. The study presented here offers a new test that can be used in conjunction with my evaluation to determine if a questionable lesion is in fact melanoma. The test was developed to take into account the gene expression of the lesion which may factor in characteristics that I cannot visually observe. The test was validated and has shown very promising accuracy metrics.

MedicalResearch.com Interview with: Yashu Dhamija MD Dr. Thomas Schmidlin, MD Cleveland Clinic Akron General  MedicalResearch.com: What is the background for this study? Response: We are seeing an increased use of face masks in the COVID-19 pandemic and while that is encouraged and necessary to limit the spread of disease in the general publication, it can mean challenges for some individuals. Patients with known sensitizations to allergens contained in face masks may experience rash or irritation with commonly used face coverings. It is also possible for patients without a history of contact dermatitis to become sensitized to allergens after wearing facial coverings more regularly, thus leading to new cases of contact dermatitis (CD) in individuals with no known prior history of contact dermatitis.

If you have experienced suicidal thoughts or have lost someone to suicide and want to seek help, you can contact the Crisis Text Line by texting "START" to 741-741 or call the Suicide Prevention Lifeline at 800-273-8255.  MedicalResearch.com Interview with: David-Dan Nguyen, MPH Research Fellow | Center for Surgery and Public Health, Brigham and Women's Hospital Medical Student | McGill University MedicalResearch.com: What is the background for this study? Response: There is ongoing concern about the side-effects of finasteride, a drug used for the management of alopecia and benign prostatic hyperplasia. These concerns have led to the coining of the “post-finasteride syndrome” which remains controversial. Indeed, there is conflicting evidence on the post-finasteride syndrome/adverse events associated with finasteride. We wanted to contribute to this conflicting body of evidence by examining suicidality, depression, and anxiety reports linked to finasteride use using the WHO’s pharmacovigilance database, VigiBase. Such pharmacovigilance databases are useful for the study of rare adverse events that are suspected to be associated with medication use.

MedicalResearch.com Interview with: Selin Tokez, PhD Student Department of Dermatology Erasmus MC, Rotterdam MedicalResearch.com: What is the background for this study? [caption id="attachment_55804" align="alignleft" width="200"]MedicalResearch.com Interview with: Selin Tokez, PhD Student Department of Dermatology Erasmus MC, Rotterdam MedicalResearch.com: What is the background for this study? Response: Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer worldwide with still increasing incidence rates. Given these high incidence rates together with the associated health costs and possibility of fatal progression, it is extremely important to have accurate and complete data on the epidemiology of this disease. Nevertheless, national cancer registries in many countries do not routinely record cSCC cases and therefore currently known numbers are mainly based on incomplete data sources. Additionally, if cSCC cases are registered, this usually only concerns the first cSCC per patient while we know that, contrary to many other malignant neoplasms, patients may develop numerous cSCCs over time. MedicalResearch.com: What are the main findings? Response: In the present study, we analyzed Dutch nationwide data comprising about 145,000 patients with a first invasive cSCC diagnosis between the years 1989 and 2017. We found that the incidence rates of a first cSCC per patient almost tripled in male patients and increased about fivefold in female patients in this 30-year time period. Also, we had data on all cSCCs per patient for the year 2017 and could therefore compare this with the data on only the first cSCC per patient: incidence rates increased by 58% for men and 35% for women when multiple cSCCs were considered. In absolute numbers, this resulted in an increase of 45% in cSCC diagnoses in 2017. Lastly, we extended our analyses by predicting future cSCC incidence rates up to 2027. Given that no substantially effective measures are undertaken in the near future, current cSCC incidence rates will increase with 23% in males and 29% in females in the next decade. MedicalResearch.com: What should readers take away from your report? Response: We could summarize our main message in two points: while people generally know that cSCC is a very common disease with increasing incidence rates, it is not taken into account that these numbers are often based on incomplete data registries and that the real numbers are even higher. In this paper, we provided these numbers for a period of 30 years based on highly accurate data from the Netherlands Cancer Registry. On top of that, as a second main finding, we showed that the real burden caused by cSCC is approximately 50% higher (taken males and females together) when all cSCC diagnoses in 1 year are registered instead of only the first tumor per patient. Together with our prediction analyses that showed an on average 26% further increase for the coming decade, this will have enormous implications for the dermato-oncological health care planning and cost management. Our results urgently call for revision of skin cancer health policies to be able to cope with this rising burden of cSCC management. Ultimately, primary prevention will remain the key strategy to halt the increasing trend in cSCC incidence and the occurrence of multiple cSCCs per patient, which we hope to further stimulate with our paper as well. MedicalResearch.com: What recommendations do you have for future research as a result of this work? Response: As we had data on multiple cSCCs for only one year, we would suggest to perform trend analyses for multiple cSCCs per patient as well when a longer follow-up duration has been reached. Furthermore, it would be very relevant to identify high-risk cSCCs or patients at risk for multiple cSCCs in order to be able to establish efficient follow-up regimens and take these high risk groups into account when revising skin cancer health policies.

MedicalResearch.com Interview with: [caption id="attachment_55788" align="alignleft" width="125"]Dr. Douglas Maslin, MPhil, MB BCHir Dermatologist and Pharmacologist Addenbrooke's Hospital Cambridge, UK Dr. Maslin[/caption] Dr. Douglas Maslin, MPhil, MB BCHir Dermatologist and Pharmacologist Addenbrooke's Hospital Cambridge, UK   MedicalResearch.com: What is the background for this study? Response: I’d like to answer this question in three parts: EVELO BIOSCIENCESFirstly, the background to Evelo and the therapeutic EDP1815: Evelo is developing orally administered biologic medicines based on a new understanding of how systemic inflammation is controlled. Evelo’s medicines are selected for their ability to modulate the small intestinal axis, or SINTAX, a network of anatomical and functional connections that has evolved to connect the small intestine with the rest of the body. SINTAX links small intestinal mucosal immunology with systemic inflammation and is now accessible with oral medicines. This inflammatory control pathway may enable a new class of products which are effective, safe, and can be manufactured affordably at large scale. EDP1815 is a non-live pharmaceutical preparation of a strain of the bacterium Prevotella histicola isolated from the duodenum of a human donor. Its pharmacodynamic effect is through interactions with the immune cells within the small intestine and it has no systemic absorption. These local interactions in the small intestine then downregulate systemic inflammation. In fact, the inflammatory control afforded by targeting the small intestinal axis appears to result in the coordinated downregulation of multiple inflammatory pathways without immunosuppression, mimicking the body’s normal physiological processes of inflammation resolution. Secondly, there is the key and exciting background pre-clinical data on EDP1815 – the details of which have been published today at the EADV conference. For example, oral administration of EDP1815 to mice has been shown to lead to striking therapeutic effects in in vivo models of delayed-type hypersensitivity, imiquimod-induced skin inflammation, fluorescein isothiocyanate cutaneous hypersensitivity, collagen-induced arthritis, and experimental acute encephalomyelitis (EAE). The consistency of effect and dose shows that EDP1815 can coordinately resolve systemic inflammation across TH1, TH2 and TH17 pathways. This suggests the potential for clinical benefit across multiple diseases. And, thirdly, there is the clinical unmet need for an oral, safe, effective treatment specifically for mild and moderate psoriasis patients, who have very limited treatment options outside of the poorly tolerated topical therapies, and these patients are reported to be dissatisfied with treatment options and therefore are often under-treated. These three points explain the background to EDP1815 and the reason for progressing forward into the phase 1b in psoriasis.

Response: Halobetasol and Tazarotene work by complimentary mechanisms of action in treating psoriasis and also have been shown to counteract the side effects associated with the other medications. In prior studies using tazarotene as monotherapy, there was a maintenance of effect even after the drug was discontinued. We investigated to see if there was a maintenance of treatment effect in patients who achieved clear skin after using the fixed combination of halobetasol propionate 0.01%/tazarotene 0.045% lotion for 8 weeks of daily treatment. 

I served as lead author on the study, which was presented Fall Clinical Dermatology Conference this weekend in a poster titled, “Long-term management of moderate-to-severe plaque psoriasis: maintenance of treatment success following cessation of halobetasol propionate 0.01%/tazarotene 0.045% lotion.”

Understanding how to functionally regenerate skin can improve the quality of life for individuals with large scars. Importantly, our study is proof of concept, in that we identified a genetic factor that allows adult skin to repair itself like the skin of a newborn babe. The discovery has implications for better skin wound treatment as well as preventing some of the aging process in skin.

Response: Parkinson’s disease (PD) is the second most common age-related neurodegenerative disorder. It is characterized by the accumulation of pathologically misfolded α-synuclein (αSynP) aggregates in the brain. Currently, a definite diagnosis relies on the detection of αSynP-containing Lewy bodies in the brain of PD patients. Development of a reliable and sensitive assay for αSynP in easily accessible peripheral tissue specimens is critical for early or differential diagnosis, determination of disease severity, and evaluation of therapeutic efficacy in clinical trials. Previous studies have revealed that the pathologically phosphorylated α-synuclein is detectable with traditional immunohistochemistry (IHC) and immunofluorescence (IF) microscopy but the sensitivity with IHC/IF is highly variable and inconsistent. Also the prion-like aggregation seeding activity of αSynP is detected in cerebrospinal fluid (CSF) of Parkinson’s disease patients with highly sensitive real-time quaking-induced conversion (RT-QuIC) and protein misfolding cyclic amplification assays (PMCA). But the lumbar puncture to collect CSF is more invasive compared to skin punch biopsy.

Botox treatment was created to make undesirable physical lines less visible. It is an efficient way to bring the natural facial appeal back to its normal condition. By getting quick and painless Botox injections, you can maintain the appearance you want most. There are a lot of myths surrounding the treatment, but the popularity of Botox is a very real thing.

botox-facial-fillers-wrinkles-skin care The Stars Know

When you hear about Botox, it is usually attached to a celebrity story. This type of treatment is very popular in Hollywood circles, and for good reason. It is an effective way to keep a specific look without major cosmetic surgery. When time is of the essence, Botox has no equal. You can set up an appointment, get the injections, and see results as early as three days. That is a single weekend required to get good looking results without breaking the bank. Hollywood is a business that relies on looks, so the popularity of Botox is no surprise. Its effectiveness on the most beautiful people in the world is the main reason why it’s still trending.

MedicalResearch.com Interview with: Yin Zhang MD Research Fellow in Medicine Brigham and Women's Hospital and Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Among modern hair dyes, permanent hair dye is the most popular type, and is the most aggressive and extensively used type that has posed the greatest potential concern about cancer risk. Monitoring and investigating the carcinogenic hazard to people from personal use of permanent hair dyes has major public health implications. In 2008, the World Health Organization's International Agency for Research on Cancer, after comprehensive reviewed prior evidence, classified occupational exposure to hair dyes as a probable carcinogen to humans (group 2A), whereas personal use of hair dyes was not classifiable as to its carcinogenicity to humans (Group 3). Data on hair dye safety has also been continuously monitored by the USFDA. Prior epidemiological evidence may have been influenced by not discriminating between personal and occupational exposure, an inability to distinguish types and colors of hair dyes used, imprecise assessment of several critical domains of exposure history (duration, frequency and cumulative dose), and inadequate control for potential confounding.

MedicalResearch.com Interview with: Elizabeth Laws, PhD Vice President and Global Project Head for Dupilumab/Dupixent Sanofi Marcie Ruddy, MD, MA Strategic Program Direction, Immunology and Inflammation Regeneron  Dr. Laws and Dr. Ruddy discuss the FDA approval of a 300 mg single-dose pre-filled pen for Dupixent® (dupilumab) for all indications in patients aged 12 years and older.   [caption id="attachment_54997" align="alignleft" width="200"]Dupixent is a biologic therapy that works differently from existing therapies that treat atopic diseases Dupixent is a biologic therapy that works differently from existing therapies that treat atopic diseases[/caption] MedicalResearch.com: What is the background for this announcement? What are the main indications for Dupixent? Response: Until now, Dupixent 300 mg dose was available only in pre-filled syringe for administration. The approval of the pre-filled pen provides an additional, easy-to-use option for patients to self-administer Dupixent. Dupixent is approved to treat patients aged 6 years and older with uncontrolled moderate-to-severe atopic dermatitis (AD) and can be used with or without topical treatments. Dupixent is also approved for use with other medicines for the maintenance treatment of uncontrolled moderate-to-severe eosinophilic or oral steroid dependent asthma in patients aged 12 years and older, and with other medicines for the maintenance treatment of uncontrolled chronic rhinosinusitis with nasal polyposis (CRSwNP) in adults, respectively. The pre-filled pen is approved for use in patients prescribed Dupixent who are 12 years of age and older across current indications, at the 300 mg dose.

Associate Professor and Director of Research Department of Dermatology The Warren Alpert Medical School of Brown University. Dr. Eunyoung Cho[/caption] Eunyoung Cho, Sc.D. Associate Professor and Director of Research Department of Dermatology The Warren Alpert Medical School of Brown University. MedicalResearch.com: What is the background for this study? Response: We are interested in whether flares of alopecia area (AA), one of the most common autoimmune diseases resulting in sudden loss of scalp and facial hair, follow seasonal patterns and whether these potential patterns are related to climate factors.  We recently analyzed a set of data on pediatric AA flares, which demonstrated seasonal patterns, with the largest number of flares in the fall, finding that climate factors such as UV index were correlated with the AA flare frequency of patients in Philadelphia, Pennsylvania, a geographical region with four distinct seasons.  Here, we explored the seasonal patterns and contribution of climate factors in pediatric AA patients in Providence, Rhode Island, another geographical region with four distinct seasons, to test whether we can replicate our previous findings.

Ludwig is a 4th year medical student at the University of Illinois Chicago College of Medicine. Her interests in dermatology include inflammatory and genetic conditions, especially within pediatric dermatology.   [caption id="attachment_54948" align="alignleft" width="163"]Alyssa M. Thompson Alyssa M. Thompson[/caption]   Alyssa M. Thompson is currently a 2nd year medical student at the UA-COM Tucson. She graduated from the University of Arizona, Summa Cum Laude in 2018 as the athletic department's Valedictorian with a degree in Physiology and an Entrepreneurship certificate. Her passion for research and dermatology stems from her innovative and integrative mindset with specific interest in inflammatory skin disease.     MedicalResearch.com: What is the background for this study? Response: Eczema is very common in children. Prescription medications are important for managing eczema flares, but a lot of the work in treating eczema is preventative, done by consistently moisturizing the skin at home with drug store products. Allergic contact dermatitis occurs more commonly in people with eczema. A previous study was done in characterizing the allergenic potential of drug-store moisturizers and found that 88% of moisturizers contain at least one common allergen. Many moisturizers are marketed specifically to eczema, but the allergen content of these products are unknown.

What are the main findings?  Response: Atopic dermatitis is a common pediatric skin condition that often begins during infancy. Kids and families alike suffer from the itching and demanding care required to manage this condition. While existing studies have examined the impact of race on atopic dermatitis from birth to adulthood, few studies have examined the early childhood period specifically. As this time is the peak period for diagnosis, we sought to examine the impact of race on disease prevalence during early childhood.

What is the importance of differentiating these two skin conditions?   Response: The background is that up to now skin biopsies were considered the gold standard for obtaining skin biomarkers of atopic dermatitis/AD and psoriasis that are linked to disease activity in skin and for obtaining the cutaneous gene and protein expression fingerprint of each individual disease. Biopsies are also used in clinical trials to obtain the skin phenotype. However biopsies are invasive, painful and scarring. Thus we need less invasive means to profile diseases and obtain biomarkers. Tape strips is a minimally invasive approach to sample and study the skin. However, prior studies using tape strips could not fully capture the phenotype of the diseases and also sampling the recovery rate was less than optimal, not allowing this approach to be widely used. Psoriasis and AD are the most common inflammatory skin diseases, but these diseases are treated very differently and in some cases are very difficult to differentiate between them clinically and even in biopsies.

MedicalResearch.com Interview with: [caption id="attachment_54803" align="alignleft" width="160"]Julie C. Harper, MD Clinical Associate Professor of Dermatology University of Alabama-Birmingham Dr. Harper[/caption]   Julie C. Harper, MD Clinical Associate Professor of Dermatology University of Alabama-Birmingham MedicalResearch.com: What is the background for this study? How common is rosacea? What are the clinical manifestations of facial rosacea or psoriasis? 
    • In 2018, the initial Beyond the Visible report provided new insights into rosacea and the psychosocial burden associated with invisible symptoms. These insights further highlighted how little is really known of the burden faced by those suffering from facial skin diseases. In this new 2020 report, Beyond the Visible: rosacea and psoriasis of the face, we explored new dimensions of the burden faced by both rosacea and psoriasis of the face patients to learn from patients’ experiences and behaviors to better inform treatment based on the comparisons and contrasts. The survey spanned six countries, 300 rosacea patients and 318 psoriasis of the face patients to answer three questions:
      • What is the burden faced by patients with psoriasis of the face and of rosacea?
      • How does the burden faced by rosacea patients differ from patients with psoriasis of the face?
      • What can we learn to help both patients and doctors to achieve the best possible outcomes for their patients?
    • Rosacea is more common than people might initially assume. There are an estimated 16 million Americans with rosacea, building up to 415 million rosacea sufferers worldwide.
    • Rosacea is commonly characterized by persistent redness and facial flushing, inflammatory lesions which may resemble acne-like bumps, visible blood vessels, and skin thickening. However, it’s important to note that rosacea symptoms vary person to person. Psoriasis of the face symptoms present themselves as red, scaly lesions that are usually along the forehead, hairline and ears. Moreover, psoriasis is known to be associated with itching, while rosacea sufferers have reported burning and stinging.

MedicalResearch.com Interview with: Dr Herman Anne MD Service de Dermatologie Cliniques Universitaires Saint-Luc   MedicalResearch.com: What is the background for this study? [caption id="attachment_54718" align="alignleft" width="200"]MedicalResearch.com Interview with: Dr Herman Anne Service de Dermatologie Cliniques Universitaires Saint-Luc Avenue Hippocrate, 10 1200 Bruxelle MedicalResearch.com: What is the background for this study? Response: In the context of the COVID-19 pandemic, several cases of acro-located lesions (on foot or hands) suggestive of chilblains have been reported and were possibly related to COVID-19. We wanted to determine if chilblains, observed in many patients recently referred to our department, are indicative of COVID-19. MedicalResearch.com: Would you briefly explain what is meant by chilblains? Response: Chilblains are frequent cold induced inflammatory lesions. Chilblains are typically seen in winter and occur after repeated exposure to cold temperatures. Clinical presentation includes erythema and swelling on toes and/or digits followed by red-purple macules or patches. However, given the large number of patients affected, and the exceptionally high outdoor temperatures for the spring season over the past month and at the time of case-observation, cold-exposure seemed unlikely. These lesions were, therefore, suspected to be associated with COVID-19. However, to date, no study has proven a pathological link between these lesions and COVID-19. MedicalResearch.com: What are the main findings? Response: In our series of 31 patients who recently developed chilblains, negative nasopharyngeal swabs and the absence of anti-SARS-CoV-2 blood immunoglobulin (Ig)M and IgG antibodies in all patients included in your study suggested that these patients had not been infected with COVID-19. These lesions appeared not to be directly related to COVID-19. MedicalResearch.com: What should readers take away from your report? Response: One hypothesis points to an indirect consequence of the COVID-19 pandemic due to imposed community containment and lockdown measures. Indeed, all patients in this study had either been working from home or were home-schooled since the beginning of containment measures in Belgium (March 11, 2020) or were temporarily unemployed. As a result of containment measures, the majority (64.5%) of patients reported a decrease in their physical activity and significantly more time spent in sedentary positions in front of screens. Most of the patients declared that they remained barefoot or in socks most of the day. All these lifestyle changes can be considered as risk factors for developing chilblains. Therefore, it seems plausible that containment, through its collateral effects, may induce chilblains. Interestingly also, the mean BMI of the patients included was relatively low, suggesting that thin people may be more at risk of developing chilblains. MedicalResearch.com: What recommendations do you have for future research as a result of this work? Response: During the current pandemic, several reports have suggested a possible link between cutaneous manifestations including aural lesions such as chilblains, and COVID-19, however, only few patients were tested for SARS-CoV-2 by RT-PCR and no serologic tests were performed. Therefore, reliable testings (RT-PCR and serologic testing) are essential to confirm a potential association with COVID-19. Citation: Herman A, Peeters C, Verroken A, et al.

Silverberg MD PhD MPH Assistant Professor in Dermatology Medical Social Sciences and Preventive Medicine Northwestern University, Chicago, Illinois Dr. Jonathan Silverberg[/caption] Dr. Jonathan L. Silverberg MD PhD MPH Assistant Professor in Dermatology Medical Social Sciences and Preventive Medicine Northwestern, Chicago, Illinois MedicalResearch.com: What is the background for this study? Response: Topical anti-inflammatory therapy is often inadequate to achieve disease control in patients with moderate-to-severe atopic dermatitis (AD), and systemic therapy is often warranted. Tralokinumab is a fully human immunoglobulin G4 monoclonal antibody that specifically binds to the IL-13 cytokine with high affinity and inhibits downstream IL-13 pro-inflammatory signaling. Tralokinumab was previously studied as a monotherapy in moderate-severe AD in the ECZTRA1 and ECZTRA2 studies. In this Phase 3 randomized controlled study, ECZTRA3, tralokinumab was studies in combination with topical corticosteroids compared to placebo with topical corticosteroids. The use of topical anti-inflammatory therapy is more akin to the way in which systemic and biologic therapies are typically used in the real-world.

MedicalResearch.com Interview with: [caption id="attachment_54684" align="alignleft" width="125"]Dr. Shumel Dr. Shumel[/caption] Brad Shumel, MD Senior Director of Medical Affairs, Immunology Regeneron MedicalResearch.com: What is the background for this study? Response: Atopic dermatitis is a chronic inflammatory disease and one of the most common skin disorders in children. Severe atopic dermatitis is characterized by skin lesions that often cover a large body surface area and can include intense, persistent itch. Uncontrolled moderate-to-severe atopic dermatitis can have a physical, emotional and psychosocial impact on children, resulting in sleep deprivation, activity restriction, poor school performance, depression and anxiety that can have a greater impact on quality-of-life. The standard of care for this pediatric population has been topical corticosteroids. Children with severe atopic dermatitis who remain uncontrolled with topical therapies have limited treatment options. This Phase 3 trial was conducted to evaluate the safety and efficacy of dupilumab plus topical corticosteroids (TCS) compared with TCS alone in children with uncontrolled severe atopic dermatitis across two treatment arms – every four weeks and every two weeks (Q4W and Q2W).
