Author Interviews, Dermatology, Melanoma / 08.05.2020

MedicalResearch.com Interview with: Neelam A. Vashi, MD Associate Professor of Dermatology Director, Boston University Center for Ethnic Skin Director, Cosmetic and Laser Center Boston University School of Medicine and Daniela P.Sanchez BS Boston Medical Center Boston, MA 02118 MedicalResearch.com: What is the background for this study? Response: Although melanoma most commonly affects Caucasians, Hispanics are disproportionately affected by greater morbidity and mortality rates when diagnosed. Poor prognosis in Hispanic patients is likely multifactorial, and may be secondary to lack of knowledge or misconceptions about melanoma risk, atypical presentation, impaired access to care, and language barriers, ultimately resulting in a delay in diagnosis.

Author Interviews, Dermatology, Neurology / 28.04.2020

MedicalResearch.com Interview with: Santosh K. Mishra M.Tech., PhD Assistant Professor of Neuroscience Department of Molecular Biomedical Sciences NC State Veterinary Medicine Raleigh, NC 2760 MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by atopic dermatitis? Response: Chronic allergic itch is a worldwide problem that leads to substantial health expenses,but what causes this universal urge to scratch remains elusive in chronic allergic itch. Atopic dermatitis is a common allergic skin disease that often associated with extremely itchy and inflamed skin. In our study, we showed, for the first time, a molecular pathway that is involved in chronic allergic itch as we identified an endogenous mediator (periostin) and a new role for its sensory neuron receptor, the integrin αVβ3, which drives the excitability and transmission of itch signal to the spinal cord.  (more…)
Author Interviews, COVID -19 Coronavirus, Dermatology / 04.04.2020

MedicalResearch.com Interview with: Amit Gefen PhD Professor of Biomedical Engineering The Herbert J. Berman Chair in Vascular Bioengineering Department of Biomedical Engineering, Faculty of Engineering Tel Aviv University, Tel Aviv, Israel MedicalResearch.com: What is the background for this study? Response: Although we are witnessing continuous progress in medical technologies, the design of many of the most commonly used medical devices e.g. oxygen masks or cervical collars has changed very little over a period of decades. Not surprisingly, these devices are also the ones which are frequently associated with device-related pressure ulcers (DRPUs). These DRPUs are frequently a hospital-acquired injury which involves risk of infections (including e.g. sepsis and antibiotic-resistant bacteria), scarring with serious psychological consequences, additional and significant healthcare costs and a basis for liability suits and litigation. The problem is massive in Europe and the US and is most frequently encountered in clinical environments where devices are used intensively, such as in operation theatres, intensive care units and emergency care settings (in both adult and pediatric medicine), but also, in elderly care facilities where patients often have fragile skin. With the current pandemic spread of the coronavirus, facilities worldwide are experiencing a considerable rise in usage of emergency and intensive care equipment, which will very likely considerably escalate the incidence of DRPUs. Early in 2019, a committee of global experts which I have chaired, has met for two days of intensive deliberation in London UK, to start developing the first-ever international consensus document on device-related pressure ulcers . After a rigorous review process by an international review committee of other experts, this consensus report has been published as a Special Edition of the Journal of Wound Care in February 2019 (https://doi.org/10.12968/jowc.2020.29.Sup2a.S1), under the name "Device-related pressure ulcers: SECURE prevention". The publisher has kindly made this publication freely downloadable and thereby accessible and available to anyone, including all professionals who may need guidance in this regard, including clinicians, industry, regulators and academic researches.

MedicalResearch.com Interview with: Jung-Im Na, MD PhD Associate Professor, Department of Dermatology Seoul National University Bundang Hospital Korea  MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by a convolutional neural network? Response: When a very young child looks at a picture, she can easily identify cats and dogs, however, even the most advanced computers had struggled at this task until recently. Computers began to “see” with the recent advancement of Deep Learning techniques. Deep Learning is a machine learning technique that teaches computers to learn from raw data. Most deep learning methods use artificial neural network architectures, imitating human brain, and convolutional neural networks (CNN) is a particular type of deep learning architecture, imitating the visual cortex. CNN is especially powerful for recognizing images. CNN exploit the information contained in image datasets to automatically learn features and patterns. (more…)
Allergies, Author Interviews, Dermatology / 20.03.2020

MedicalResearch.com Interview with: Gil Yosipovitch, MD, Professor Miami Itch Center Lennar Medical Foundation South Miami Clinic in Coral Gables University of Miami Health System MedicalResearch.com: What is the background for this study? How does Dupilumab (Dupixent) differ from other medications for atopic dermatitis/eczema? Response: Atopic dermatitis (AD) is characterized by intense itch (pruritus) that is one of the most burdensome symptoms; therefore, rapid and sustained improvement in itch is an important marker of treatment benefit. Dupixent® (dupilumab) is approved in the U.S. for adults and adolescents with inadequately-controlled moderate-to-severe Atopic Dermatitis. Dupilumab remains the first and only biologic medicine for uncontrolled moderate-to-severe atopic dermatitis. Dupilumab is the first and only fully human monoclonal antibody that inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) proteins. Data from dupilumab clinical trials have shown that IL-4 and IL-13 are key drivers of the type 2 inflammation that plays a major role in atopic dermatitis, asthma and chronic rhinosinusitis with nasal polyps.  (more…)
Author Interviews, Dermatology, Pediatrics / 18.03.2020

MedicalResearch.com Interview with: Adawiyah Jamil, AdvMDerm Associate Professor at Department of Medicine University Kebangsaan Malaysia Medical Center Kuala Lumpur, Malaysia MedicalResearch.com: What is the background for this study? Response: We commonly observed poor dietary pattern and multiple food restrictions imposed on atopic dermatitis (AD) children by their parents in our daily clinical practice. Food allergy is often associated with AD, however excessive and medically unsubstantiated restriction may lead to various health issues. AD is a chronic skin disease, like any other chronic diseases it affects an individual’s general health. Growth and development are key measures of health in children. We embarked on this study as we were very worried of the consequences of medically unsupervised food restriction, especially those with severe disease.  We were concerned about how our atopic dermatitis children are eating and how to help them.

Allergies, Asthma, Author Interviews, Dermatology, Pediatrics / 10.03.2020

MedicalResearch.com Interview with: Marcella Aquino, M.D. Hasbro Children's Hospital Department of Pediatrics Division of Allergy & Immunology Associate Professor of Pediatrics   Daphne Koinis-Mitchell PhD Professor (Research) in the Departments of Psychiatry and Human Behavior and Pediatrics Warren Alpert Medical School of Brown University Providence, Rhode Island 02903   MedicalResearch.com: What is the background for this study? Response: Urban minority children with asthma are at increased risk for sleep loss and poorer sleep quality secondary to socio-contextual stressors (poverty, stressors of urban living) and the underlying challenges related to following possibly complex asthma treatment regimens. Atopic dermatitis (AD) is very frequently seen in children with asthma and increases the risk for poor quality sleep, for example difficulty falling asleep, awakenings during the night, difficulty awakening in the morning, and/or daytime sleepiness.  (more…)
Author Interviews, Dermatology, Immunotherapy, Science / 27.02.2020

MedicalResearch.com Interview with: Brian S. Kim, MD, MTR, FAAD Associate Professor of Medicine (Dermatology) Co-Director, Center for the Study of Itch and Sensory Disorders Division of Dermatology, Department of Medicine Washington University School of Medicine St. Louis, MO 63110 MedicalResearch.com: What is the background for this study? Response: It has been known well for decades that a specific part of your immune system called the “type 2 immune response” is overactive in atopic disease. Indeed, that is what new drugs like dupilumab block so effectively and thus revolutionized the treatment of atopic disorders just in the last few years. In fact, our lab focuses predominantly on this part of the immune system. However, increasingly it is becoming recognized that the immune system is not just about whether it is “on or off” but rather a balance like yin and yang. Along these lines, we noticed that a cell that could theoretically counterbalance atopic inflammation was significantly deficient in many patients with eczema. This cell is the natural killer (NK) cell. (more…)
Author Interviews, Cancer Research, Dermatology, JAMA / 19.02.2020

MedicalResearch.com Interview with: Nikolai Dyrberg Loft MD, Ph.D.-fellow Department of Dermatology and Allergy Gentofte Hospital Hellerup MedicalResearch.com: What is the background for this study? Response: Epidemiological studies examining the association between psoriasis or psoriatic arthritis and cancer have reported conflicting results. Some studies report an increased risk of cancer in individuals with psoriasis or psoriatic arthritis and others do not. Whether individuals with psoriasis or psoriatic arthritis have an increased risk of cancer is important as this might help guiding in clinical practice. In order to determine if there is an increased risk of cancer and the magnitude of this risk, a systematic review of the literature and meta-analysis is needed.  (more…)
Author Interviews, BMJ, Dermatology, Technology / 13.02.2020

MedicalResearch.com Interview with: Professor Jon Deeks PhD, CStat Institute of Applied Health Research Professor of Biostatistics College of Medical and Dental Sciences University of Birmingham, UK MedicalResearch.com: What is the background for this study? Response: Skin cancer is one of the most common cancers in the world, and the incidence is increasing. In 2003, the World Health Organization estimated that between two and three million skin cancers occur globally each year, 80% of which are basal cell carcinoma, 16% cutaneous squamous cell carcinoma, and 4% melanoma. The potential for melanoma to metastasise to other parts of the body means that it is responsible for up to 75% of skin cancer deaths. Five year survival can be as high as 91-95% for melanoma if it is identified early, which makes early detection and treatment key to improving survival. Early detection of melanoma is reliant on people with new or changing moles seeking early advice from medical professionals. Skin cancer smartphone applications (“apps”) provide a technological approach to assist people with suspicious lesions to decide whether they should seek further medical attention. Of increasing interest are smartphone apps that use inbuilt algorithms (or “artificial intelligence”) that catalogue and classify images of lesions into high or low risk for skin cancer (usually melanoma). Apps with inbuilt algorithms that make a medical claim are now classified as medical devices that require regulatory approval. These apps could be harmful if recommendations are erroneous, particularly if false reassurance leads to delays in people obtaining medical assessment.  CE (Conformit Europenne) marking has been applied to allow distribution of two algorithm based apps in Europe (SkinScan and SkinVision), one of which is also available in Australia and New Zealand. However, no apps currently have United States Food and Drug Administration (FDA) approval to allow their distribution in the US and Canada. We have completed a systematic review of studies that examine the accuracy of all apps that use inbuilt algorithms to identify skin cancer in users of smartphones.  We report on the scope, findings, and validity of the evidence.

Comments from the FDA on this JAMA Dermatology study: Effect of Sunscreen Application on Plasma Concentration of Sunscreen Active Ingredients: A Randomized Clinical Trial  Sunscreen CDC Phil imageMedicalResearch.com: What is the background for this study? Response: A prior pilot study published in JAMA in May 2019 demonstrated the systemic absorption of 4 sunscreen active ingredients; additional studies are needed to determine the systemic absorption of additional active ingredients, and how quickly absorption occurs.  This study assessed the systemic absorption of the 6 active ingredients (avobenzone, oxybenzone, octocrylene, homosalate, octisalate and octinoxate) in 4 sunscreen products under single and maximal-use conditions.  (more…)
Author Interviews, Depression, Dermatology, Pediatrics / 21.01.2020

MedicalResearch.com Interview with: Dr. Jonathan L. Silverberg MD PhD MPH Director of Clinical Research and Contact Dermatitis Associate Professor of Dermatology George Washington University School of Medicine and Health Sciences Washington, DC  MedicalResearch.com: What is the background for this study? Response: We previously found that children from single parent families, and unsafe or unsupportive neighborhoods are more likely to have atopic dermatitis. Parents in these settings may experience greater psychosocial distress and higher rates of depression in the post-partum period and beyond. As such, we sought to understand the relationship of maternal depression with atopic dermatitis in their children. (more…)
Author Interviews, Dermatology, Mental Health Research, Pediatrics / 15.01.2020

MedicalResearch.com Interview with: Lucia Diaz, M.D., is chief of pediatric dermatology, dermatology residency associate program director and assistant professor of medicine and pediatrics at Dell Medical School. She is also co-director of the dermatology-rheumatology combined clinic at Dell Children’s Medical Center. Sasha Jaquez, Ph.D. is a pediatric psychologist at Dell Children's Medical School/Dell Children's Medical Center and specializes in seeing children with chronic medical illness, including skin disorders.     MedicalResearch.com: What is the background for this study? Response: Trichotillomania (TTM) can be an extremely disabling chronic condition that impacts the psychosocial development of children. It is classified by the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as an obsessive-compulsive disorder, where a person recurrently pulls out hair from any region of their body resulting in hair loss. Recognizing this disorder and being informed of treatment options allows medical providers to correctly diagnose and intervene early in the disease course. We reviewed the psychosocial impacts of pediatric trichotillomania and the current evidence-based interventions used in the population.  (more…)
Author Interviews, Dermatology, Education, Gender Differences, JAMA, Race/Ethnic Diversity / 08.01.2020

MedicalResearch.com Interview with: Imam Xierali, PhD Associate Professor / UT Southwestern Medical Center Dallas, Texas MedicalResearch.com: What is the background for this study? Response: Despite the continued efforts in academic medicine to increase the representation of women and minorities underrepresented in medicine (URM), there is a lack of information on trends in dermatology department faculty diversity and how they compare with those in other clinical departments. (more…)
Author Interviews, Dermatology, HPV, Infections, JAMA, OBGYNE / 08.01.2020

MedicalResearch.com Interview with: Niklas Worm Andersson, MD Department of Clinical Pharmacology, Copenhagen University Hospital Bispebjerg and Frederiksberg, Copenhagen NV, Denmark MedicalResearch.com: What is the background for this study? What is Podophyllotoxin used for? Response: Podophyllotoxin is an antimitotic agent primarily used in the local treatment of anogenital warts, which are among the most prevalent sexually transmitted diseases worldwide. Most women affected by anogenital warts are of childbearing age and during pregnancy, they may become symptomatic, enlarge, or multiply. While podophyllotoxin is part of first-line treatment of anogenital warts for the non-pregnant population, it is contraindicated during pregnancy. Fetal safety data are limited and to our knowledge, no previous human data exist to help inform on this issue. (more…)
Author Interviews, Brigham & Women's - Harvard, Dermatology, Science / 05.01.2020

MedicalResearch.com Interview with: Dr. D. Branch Moody, MD Principal Investigator Associate Physician, Brigham and Women's Hospital Professor of Medicine, Harvard Medical School MedicalResearch.com: What is the background for this study? Is the CD1a molecule found on the skin's Langerhans cells? Response: With increasing industrialization worldwide, people apply cosmetics and other consumer products to the skin, leading to contact dermatitis, which is becoming increasingly common. Immunologists know that T cells participate in dermatitis reactions. However, T cells usually recognize and respond to antigens that are peptides rather than the non-peptide antigens that cause contact dermatitis. (more…)
Author Interviews, Dermatology / 20.12.2019

MedicalResearch.com Interview with: Dr Kim Kjoeller MD Executive Vice President, Global Research & Development LEO Pharm Discusses the recent announcement from  LEO Pharma A/S that tralokinumab  met all primary and secondary endpoints in its three Phase 3 studies (ECZTRA 1-3) for the treatment of moderate-to-severe atopic dermatitis in adults. MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by Atopic Dermatitis? Response: Atopic Dermatitis (AD) – also known as ‘atopic eczema’ – is a chronic, inflammatory, heterogeneous skin disease characterized by intense itch and eczematous lesions is the most common inflammatory skin disease in the world, with limited effective treatment options, especially for moderate-to-severe patients. The primary objective of these studies was to evaluate the efficacy of tralokinumab compared with placebo in treating moderate-to-severe atopic dermatitis.
  • ECZTRA 1 and 2 evaluated the use of tralokinumab as monotherapy
  • ECZTRA 3 evaluated the use of tralokinumab in combination with a topical corticosteroid (TCS).

MedicalResearch.com Interview with: Lily Wang Student at University of Toronto Toronto, Ontario, Canada  MedicalResearch.com: What is the background for this study? Response:  Impaired skin barrier and aberrant immune function in atopic dermatitis (AD) may impact immune response to malignancy. Conflicting data exist on the risk of cancer in patients with AD. The purpose of our study was to determine the risk of non-cutaneous and cutaneous cancers in patients with atopic dermatitis compared to the general population (i.e. without AD).  (more…)
Aging, Dermatology, JAMA / 26.11.2019

MedicalResearch.com Interview with: Christian Sell, PhD Associate Professor of Biochemistry and Molecular Biology Drexel University College of Medicine MedicalResearch.com: What is the background for this study? Response: In terms of background, the drug rapamycin targets a pathway that scientists know is critical for growth and development but is also a key regulator of lifespan in many model organisms such as worms, flies, and mice. This pathway is known as the mTOR pathway. Rapamycin is already in use clinically, it is given to people who have received organ transplants to prevent rejection and is also in trials to treat some forms of cancer, at very high doses. Many studies in mice have shown that rapamycin delays aging and prevents age-related disorders such as the decline in heart function and cognitive function. Based on this work, there is a strong expectation that these results will translate into humans, but no studies have been done due to concerns regarding potential side effects of rapamycin when the drug is given orally to prevent rejection. Our previous studies have shown that a very low dose of rapamcyin can reduce the aging of human cells and improve cell growth, while the high does used for organ transplant patients actually block cell growth.  We decided to test the impact of low dose rapamycin on aging in the skin because we could treat people safely. Previous studies have shown that the drug does not get into the blood stream when high doses were given topically to people with a rare genetic disorder, so we knew that the low doses used in our study would not get into the bloodstream and would be safe for the patients.

MedicalResearch.com Interview with: Markus Boos, MD, PhD Member of the Society for Pediatric Dermatology. Attending pediatric dermatologist Seattle Children's Hospital Assistant Professor in the Department of Pediatrics University of Washington School of Medicine  MedicalResearch.com: What is the background for this study? Response: Our understanding of the cutaneous health of sexual and gender minority (SGM) individuals (lesbian, gay, bisexual, transgender, queer, asexual, intersex, nonbinary, etc.) remains nascent. This dearth of understanding of the unique needs of SGM children is even more pronounced. This 2-part review article provides practical advice on how to best engage with young SGM patients and serve the distinct needs of this minority population, with a specific emphasis on dermatologic conditions.

Author Interviews, Dermatology, JAMA, Melanoma / 17.11.2019

MedicalResearch.com Interview with: Jennifer M. Gardner, MD Clinical Assistant Professor of Dermatology University of Washington School of Medicine  MedicalResearch.com: What is the background for this study? Response: This study looked at age-specific differences of melanoma incidence in the United States. It was an observational study looking at population-based registry data extracted from the combined National Program of Cancer Registries-Surveillance Epidemiology and End Results United States Cancer Statistics (NPCR-SEER) database. The overall take home message from this study is that though melanoma incidence has continued to climb in the past decade for both men and women, most of the increase is seen in adults greater than age 40 years of age.  In contrast, melanoma incidence decreased in adolescents (ages 10-19 years of age) and young adults (ages 20-29) after peaking around 2004-2005. Melanoma is more common in males in older individuals (older than 50 years of age) but in younger individuals (<50 years of age), melanoma is more common in females.  According to a recently published JAMA-Otolaryngology paper by Bray and colleagues, there may be a subset of younger individuals where males are at a higher risk than females in regard to head and neck melanoma, and after that study was published we noted this to be true in our numbers, as well (we didn’t publish this in our study), further identifying a possibly “at risk” demographic within the younger age groups in addition to young women.

Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, Dermatology, JAMA, Rheumatology / 09.11.2019

MedicalResearch.com Interview with: Emily S. Ruiz, MD, MPH Director, High-Risk Skin Cancer Clinic, Dana Farber/Brigham and Women’s Cancer Center Assistant Professor, Harvard Medical School, Dermatology Brigham And Women's Faulkner Hospital  MedicalResearch.com: What is the background for this study? Response: Innovation in oncology has led to increased development and market entry of anticancer drugs. For example, from 2009 to 2013, the US FDA approved 51 oral and systemic anticancer drugs for 63 indications. Prices for anticancer drugs have risen faster than inflation over time, especially for older drugs, and prices in the US have largely been set by market forces rather than novelty or efficacy. Understanding the evolving cancer economic landscape requires consideration of annual and cumulative rates of change for key metrics, such as total spending, drug cost per beneficiary, out-of-pocket cost, and utilization. This study sought to weigh the proportional impacts of rising drug costs and utilization on increased Medicare Part D spending for a cohort of oral anticancer drug utilized from 2013-2017.  (more…)
Author Interviews, Dermatology / 25.10.2019

MedicalResearch.com Interview with: Dr. Stephan Weidinger, MD, MaHM Professor of Dermatology Christian-Albrechts-Universit Kiel  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Relatively little is known about the epidemiology and burden of Atopic Dermatitis (AD) in children, adolescents and adults, however, there is increasing evidence that the disease is highly prevalent also in these age groups. Further, very little is known about the disease severity strata. Severity, however, largely defines treatment needs. The EPI-CARE (EPIdemiology of Children with Atopic dermatitis Reporting on their Experience) study was a cross-sectional web-based study of the prevalence and burden of AD in both children and adolescents. It was performed globally across Europe, North America (US, Canada), Latin America (Argentina, Brazil, Colombia, Mexico), Asia (Japan, Taiwan), the Middle East (Israel, Kingdom of Saudi Arabia, Turkey, the United Arab Emirates) and Russia, and used very stringent definitions of AD and the same methodology across age groups. We first analyzed the adolescent data, and it turned out that the prevalence of active Atopic Dermatitis is higher than expected, ranging from 9.29% in the US and 14.7% in Europe. Of note, almost 50% of the adolescents with current AD reported an overall moderate to severe disease activity, and the majority reported a multidimensional burden that includes not only the skin symptoms associated with AD, but also sleep disturbances, symptoms of anxiety/depression, and reductions in quality‐of‐life and productivity. Adolescents also reported a high burden of coexisting atopic diseases that increased with AD severity – 68.6% of those with moderate AD and 81% of those with severe AD reported at least one coexisting atopic disease. atopic dermatitis substantially affects the life of patients and their families, and this burden is higher with greater AD severity.

Author Interviews, Dermatology, JAMA, Melanoma, Technology / 21.10.2019

MedicalResearch.com Interview with: https://skin-analytics.com/about-us/ Dr. Helen Marsden PhD Skin Analytics Limited London, United Kingdom MedicalResearch.com: What is the background for this study? Response: In this technology age, with the explosion of interest and applications using Artificial Intelligence, it is easy to accept the output of a technology-based test - such as a smartphone app designed to identify skin cancer - without thinking too much about it. In reality, technology is only as good as the way it has been developed, tested and validated. In particular, AI algorithms are prone to a lack of “generalisation” - i.e. their performance drops when presented with data it has not seen before. In the medical field, and particularly in areas where AI is being developed to direct a patient’s diagnosis or care, this is particularly problematic. Inappropriate diagnosis or advice to patients can lead to false reassurance, heightened concern and pressure on NHS services, or worse. It is concerning, therefore, that there are a large number of smartphone apps available that provide an assessment of skin lesions, including some that provide an estimate of the probability of malignancy, that have not been assessed for diagnostic accuracy. Skin Analytics has developed an AI-based algorithm, named: Deep Ensemble for Recognition of Malignancy (DERM), for use as a decision support tool for healthcare providers. DERM determines the likelihood of skin cancer from dermoscopic images of skin lesions. It was developed using deep learning techniques that identify and assess features of these lesions which are associated with melanoma, using over 7,000 archived dermoscopic images. Using these images, it was shown to identify melanoma with similar accuracy to specialist physicians. However, to prove the algorithm could be used in a real life clinical setting, Skin Analytics set out to conduct a clinical validation study. (more…)
Author Interviews, Dermatology, Nature, Stanford / 18.10.2019

MedicalResearch.com Interview with: Stephen J. Galli, MD Mary Hewitt Loveless, MD Professor Professor of Pathology and of Microbiology and Immunology Department of Pathology Stanford University School of Medicine Center for Clinical Sciences Research Stanford, CA and Nicolas Gaudenzio PhD Unité de Différenciation Epithéliale et Autoimmunité Rhumatoïde INSERM, Université de Toulouse Toulouse, France MedicalResearch.com: What is the background for this study? What are the main findings? Response: We took a lead from existing clinical data showing that patients with moderate to severe atopic dermatitis, an increasingly common disorder producing skin pathology, also have elevated levels of neuropeptides in their blood, particularly one neuropeptide, named “substance P”, whose level is correlated with disease severity. These patients also have high levels of mast cell-specific proteases in the blood, indicating that mast cells, which are innate immune cells present in the skin, and which can be activated when exposed to substance P, might play an essential role in modulating inflammatory and allergic processes. Based on these observations, our teams (Galli Lab at Stanford University, USA and Gaudenzio Lab at Inserm Toulouse, France) decided to focus on the possible interactions between sensory neurons, which are a source of substance P, and mast cells. The results of this work have now been published in the journal Nature Immunology. (more…)

MedicalResearch.com Interview with: Eleni Linos MD MPH DrPH Professor of Dermatology and Epidemiology Stanford University  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: We know that tanning beds are harmful: people who use tanning beds are more likely to get skin cancer. Sexual minority men are much more likely to use tanning beds and also more likely to get skin cancer. In a separate study we discovered that one reason sexual minority men use tanning beds is if it is convenient: e.g. if close to home, cheap, and easy. (https://onlinelibrary.wiley.com/doi/abs/10.1111/bjd.17684). Recent research showed that tobacco retailers cluster in LGB neighborhoods: https://sph.unc.edu/sph-news/more-tobacco-retailers-in-lgbt-neighborhoods-may-explain-smoking-disparities/. This made us wonder if tanning salons also cluster in neighborhoods with more gay men.  (more…)
Author Interviews, Dermatology / 06.10.2019

MedicalResearch.com Interview with: Peter C. Friedman, M.D., Ph.D. Diplomate of the American Academy of Dermatology www.skincenterderm.com MedicalResearch.com: What is the background for this study and case series? Would you describe nonthermal atmospheric pressure plasma? Response: Plasma is essentially ionized gas, the fourth state of matter: molecules or atoms move freely in gas state but in a higher energy state atoms shed electrons and both electrons and ions then move freely and independently. If this material has a temperature close to room temperature, we call it non-thermal atmospheric pressure plasma, or cold plasma. It has been established in countless in vitro and animal experiments that cold plasma has a significant effect on living cells and tissues, for example: selective destruction of cancer cells, helping normal tissue development, inhibiting bacterial, fungal and even viral proliferation. In the handful of clinical trials it could improve wound healing, treat nail fungus. Our group was able to cure precancerous actinic keratosis lesions in a number of patients in a prior study. Based on some of the basic science data regarding the specific molecular and intracellular effects of cold plasma, we theorized that it may be able to cure warts, which are caused by human papilloma virus infection.

Allergies, Author Interviews, Brigham & Women's - Harvard, CMAJ, Dermatology, Heart Disease / 30.09.2019

MedicalResearch.com Interview with: Hyon K. Choi, MD, DrPH Professor of Medicine, Harvard Medical School Director, Gout and Crystal Arthropathy Center Director, Clinical Epidemiology and Health Outcomes Division of Rheumatology, Allergy, and Immunology Department of Medicine, Massachusetts General Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Allopurinol is a very common and generally safe medication prescribed to lower serum urate levels, most commonly to patients with gout. However, it can be associated with very rare but serious cutaneous adverse events which includes Stevens-Johnson syndrome and toxic epidermal necrolysis. Prior studies have demonstrated several risk factors for these types of cutaneous adverse events, including presence of chronic kidney disease, older age, female sex, higher initial dose of allopurinol, and the HLA-B*5801 allele, which is more commonly found in Asians and Black patients. A prior study in Taiwan suggested that heart disease (ischemic heart disease and heart failure) may also be associated with an increased risk of hospitalizations for these cutaneous adverse reactions related to allopurinol. Thus, our goal was to investigate this association using a general population cohort from Canada. Using Population Data BC, we found that heart disease was in fact independently associated with an increased risk of hospitalization for these cutaneous adverse reactions. (more…)

MedicalResearch.com Interview with: Hal Flowers MD Assistant Professor of Dermatology University of Virginia Dr. Flowers specializes in autoimmune connective tissue disease (rheumatologic dermatology), phototherapy and blistering skin diseases  MedicalResearch.com: What is the background for this study? Response: Unfortunately, there really is not much literature at all addressing the treatment of atopic dermatitis with apple cider vinegar (ACV), even though we know that this is something our patients are doing. ACV is appealing as a “natural therapy” for treatment of skin disease. Since it’s an acid, it can theoretically correct the loss of acidity that occurs in the skin of our eczema patients. Plus, we know that high enough concentrations will kill certain bacteria that promote eczema, particularly Staphylococcus aureus. There are plenty of blogs and anecdotes as well as physicians who recommend this treatment, but as of yet, we don’t know the best concentration, safety or the benefit of ACV.  (more…)
