MedicalResearch.com Interview with: Hooman Khorasani, M.D. Cosmetic Surgeon & Mohs Skin Cancer Surgeon Icahn School of Medicine at Mt. Sinai MedicalResearch.com: What is the background for this study? Response: Lipomas are tumors composed of mature fat cells located just beneath the skin surface. They are the most common soft tissue tumor and are estimated to occur in 1% of the population. These benign tumors are more common in overweight individuals, diabetics, patients with elevated serum cholesterol, and those suffering from familial multiple lipomatosis. Most of these tumors are treated for cosmetic reasons; however, large lipomas can also cause significant functional impairment. Traditional treatment includes surgical removal and / or liposuction. Deoxycholic acid is a member of the bile acid family that assists in the breakdown of fat. We investigated the use of deoxycholic acid injections to reduce the size of large lipomas prior to surgical removal. (more…)

MedicalResearch.com Interview with: Francis Alenghat, MD, PhD Assistant Professor of Medicine Section of Cardiology University of Chicago MedicalResearch.com: What is the background for this study? What are the main findings? Response: Psoriasis has been associated with higher rates of atherosclerotic cardiovascular disease (ASCVD), potentially due to higher-than-normal levels of systemic inflammation. Whether this association varies by race was unknown. Also, it was unclear whether patients with psoriasis have more frequent ASCVD because of higher rates of traditional cardiovascular risk factors (smoking, diabetes, hypertension, hyperlipidemia) or because of components intrinsic to psoriasis itself. We found that, amongst a large population of patients with psoriasis, patients of both sexes and most ages had elevated ASCVD rates compared to those without psoriasis. Overall, African American patients with psoriasis had a 15% ASCVD prevalence, whereas it was 10% in white patients with psoriasis. Increased ASCVD associated with psoriasis occurred at earlier ages in African American patients compared to white patients. Traditional cardiovascular risk factors were common in patients with psoriasis and appeared to play a large role in the driving the higher rates of ASCVD in these patients, but even in patients with psoriasis but without any documented traditional risk factors, ASCVD rates were elevated compared to patients without psoriasis.  (more…)

MedicalResearch.com Interview with: William I. Roth MD Dermatology and Dermatological Surgery Boynton Beach, FL MedicalResearch.com: What is the background for this study?
  • This retrospective study reviewed medical records of patients with biopsy-proven, primary cutaneous basal and squamous cell carcinoma (BCC and SCC) lesions on the lower extremities. These patients were treated with the Sensus Healthcare’s Superficial Radiation Therapy SRT-100 Unit between 2011 and 2014. The SRT-100 is most amenable for treating non-melanoma skin cancer (NMSC) in patients aged 65 and older although many younger patients are treated as well when a non-scarring method is desired.
  • The types of skin cancers treated included superficial, well differentiated and moderately differentiated squamous cell carcinomas, squamous cell carcinoma in situ and basal cell carcinomas including infiltrative basal cell carcinomas. Higher energy linear accelerator radiation units have been reported to have a high incidence of healing problems. With the SRT-100 the radiation is concentrated primarily in the higher layers of the skin where the skin cancer is located and thus the treatments are well tolerated.

Author Interviews, Dermatology / 19.02.2019

MedicalResearch.com Interview with: Eli Sprecher MD PhD Professor and Chair, Division of Dermatology Deputy Director General for R&D and Innovation Tel Aviv Sourasky Medical Center Frederick Reiss Chair of Dermatology Sackler Faculty of Medicine Tel Aviv University, Tel Aviv, Israel and MedicalResearch.com: What is the background for this study? Response: Central centrifugal cicatricial alopecia (CCCA) is a form of hair loss (alopecia) which is extremely common and affects one in every 20 women of African origin. It starts usually during the fourth decade of life. Because it can be inherited from mothers to their children, it is thought to have a genetic basis. On the other hand, it is known to mainly affect women who use to groom their hair intensively. Thus it was thought that the disease stems from some form of inherited susceptibility to the damage incurred to the hair follicle by grooming habits. In the study we published, we searched for the genetic basis of CCCA. In contrast with the common form of alopecia (androgenetic alopecia or female pattern alopecia), CCCA is associated with scarring of the scalp skin, which means that once hair is lost, it will likely not re-grow.

MedicalResearch.com Interview with: Lotus Mallbris, MD PhD Dermatologist and Vice President, Head of Global Immunology Drug Development Platform Team Leader at Lilly MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by atopic dermatitis? How common is this condition?  Response:The BREEZE-AD1 and BREEZE-AD2 clinical trials are multicenter, randomized, double-blind, placebo-controlled, Phase 3 studies to evaluate the efficacy and safety of baricitinib monotherapy in adult patients with moderate to severe atopic dermatitis. These are two of five studies that will be part of the placebo-controlled data program intended to support global registrations. Atopic dermatitis, a serious form of eczema, is a chronic, relapsing skin disease characterized by intense itching, dry skin and inflammation that can be present on any part of the body. It affects approximately 1-3 percent of adults worldwide. (more…)

MedicalResearch.com Interview with: Luis Garza, MD-PhD Associate Professor Department of Dermatology Johns Hopkins School of Medicine Baltimore, MD 21287 MedicalResearch.com: What is the background for this study? What are the main findings?  Do you think these findings would be similar with other antibiotics (oral or topical) or with isotretinoin for acne? Response: We prescribe antibiotics frequently for acne. We certainly know it affects our normal and abnormal bacteria on our skin. But we don’t fully understand how well or not people recover from antibiotics.  (more…)

To view a copy of this license, visit: https://creativecommons.org/licenses/by/2.0Donal J. Sexton, MD, PhD Department of Nephrology and Kidney Transplantation Beaumont Hospital Royal College of Surgeons in Ireland Dublin, Ireland MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Patients who receive a kidney transplant as treatment for end stage kidney disease are at risk of malignancy due to immunosuppression. In contrast to other solid organ transplant types, when kidney transplants fail it is possible for recipients to return to dialysis. Immunosuppression is usually reduced or completely stopped when  the allograft fails due to the risk of infection on dialysis. We decided to investigate what the trajectory of risk for non-melanoma skin cancer and invasive cancers overall (composite group) looked like for patients who have received multiple consecutive kidney transplants with intervening periods of graft failure. We compared cancer risk during periods of allograft failure and periods of functioning kidney transplants.   (more…)

MedicalResearch.com Interview with: Dr. Catherine M. Olsen Associate Professor Cancer Control Group QIMR Berghofer Medical Research Institute MedicalResearch.com: What is the background for this study? Response: Melanoma incidence and mortality rates are increasing globally. Public health campaigns aiming to reduce sun exposure and use of sunbed have been implemented in many parts of the world, but there is significant variability in terms of the history and reach of these campaigns across countries. We examined melanoma incidence rates in eight different countries with different patterns of sun exposure and varying approaches to melanoma control. (more…)

MedicalResearch.com Interview with: Dr Sarah Hall PhD Senior Lecturer in Forensic Science Anglia Ruskin University MedicalResearch.com: What is the background for this study? Response: We initially started the study in collaboration with Essex Fire and Rescue Services, as we were already doing some research on the recovery of evidence from fire scenes. During a visit to their cold fire scene facility, they described a tragic fatality with extensive fire damage, which didn’t link with the main fuel in the room. Therefore they questioned if a skin cream, regularly used by the victim, could have contributed as a fuel or ignited to initiate the fire and asked if we would do some initial research. Now we are also working with West Yorkshire and Cambridgeshire Fire and Rescue Service, the London Fire Brigade, St Andrews Centre for Plastic Surgery and Burns and the National Fire Chiefs Council.

MedicalResearch.com Interview with:

Dr. Martina Callaghan PhD Head of Physics & Senior Lecturer Wellcome Centre for Human Neuroimaging Institute of Neurology University College London London

MedicalResearch.com:  What is the background for this study?  What are the main findings?

Response: As mirrors the situation in the general population, we found that an increasing number of volunteers who were seeking to enter cognitive neuroscience studies at our Centre had tattoos. However, the magnetic fields used in magnetic resonance imaging (MRI) pose a potential safety risk for people with tattoos. A number of case reports have described such incidents.  However, as these describe isolated cases retrospectively, there was not enough information to objectively assess the risk of tattoo-related adverse reactions for persons having an MRI scan.  Therefore, in 2011, we decided to embark upon this first prospective study to quantitatively assess this risk.

MedicalResearch.com Interview with: Wenquan Zou, MD, PhD Associate Professor Departments of Pathology and Neurology Director of CJD Skin Project Associate Director National Prion Disease Pathology Surveillance Center Institute of Pathology Case Western Reserve University School of Medicine Cleveland, Ohio 44106 MedicalResearch.com: What is the background for this study? Would you briefly explain the significance of prion-induced diseases and why they have been difficult to diagnosis? Response: Our previous study has demonstrated that infectious prions are detectable in the skin samples of patients with sporadic Creutzfeldt-Jakob disease (sCJD), the most common form of human prion disease, at the terminal stage by the highly sensitive real-time quaking-induced conversion (RT-QuIC) assay and animal-based bioassay. The prion-induced diseases are significant because they are infectious diseases that can be transmitted inter-species and intra-species. For instance, mad cow disease, a prion disease in cattle, has been documented to transmit to humans. Currently, there are no cures for these fatal diseases. The definite diagnosis of prion diseases is difficult because it mainly depends on the availability of brain tissues obtained either by biopsy or autopsy for detection of prions. Brain biopsy is highly invasive and it is difficult to be accepted by patients and their families. Even for brain autopsy, it is not always feasible because of religious and cultural limitations in some regions or countries.  (more…)
Author Interviews, Depression, Dermatology, JAMA, Mental Health Research / 21.01.2019

MedicalResearch.com Interview with: Isabelle Vallerand, PhD Epidemiologist, MD Student Department of Community Health Sciences Cumming School of Medicine University of Calgary MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is well known that patients with alopecia areata, a form of autoimmune hair loss, are at a higher risk of suffering from depression than the general population. But in practice, we often hear patients tell us that they believe their hair loss developed as a result of stress or problems with mental health – certainly the phrase “so stressed your hair is falling out” is something most people have heard of. Despite this, there has actually been very little research investigating the role that mental health may have on development of alopecia areata. Interestingly, depression has recently been associated with increased systemic inflammatory markers, so there is biologic plausibility that depression could increase the risk of alopecia areata. Our group was interested in addressing this question, and used a large population-level health records database with up to 26 years of follow-up to study it. We ultimately found that not only does depression increase one’s risk of alopecia areata, but that it increases their risk by nearly 90% compared to people who have never had depression. We also found that using antidepressants can significantly decrease the risk of developing alopecia areata in patients with depression. So there appears to be an important link between mental health and development of hair loss from alopecia areata. (more…)

MedicalResearch.com Interview with: Dong Hyun Kim M.D. Associate professor Department of Dermatology CHA Bundang Medical Center CHA University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: As a dermatologist, we see many patients with newly diagnosed with bullous pemphigoid (BP), many of whom have diabetes. The use of DPP-4 inhibitors is a common treatment for diabetes, we have noted previous case reports that DPP-4 inhibitors may be the cause of BP. For this reason, we started this study. The most important thing in my article is DPP-4 inhibitors, particularly vildagliptin, may be associated with the development of bullous pemphigoid in male patients with diabetes. We have confirmed these points based on the nationwide, population-based study. It is very meaningful because there have been few studies using large sample sizes so far. (more…)

MedicalResearch.com Interview with: Yssra-SolimanYssra S. Soliman, BA Division of Dermatology, Department of Internal Medicine Albert Einstein College of Medicine Bronx, New York MedicalResearch.com: What is the background for this study? What are the main findings?  Response: As the population of the United States becomes increasingly diverse, certain fields within medicine have not followed this trend. Dermatology is the least diverse field after orthopedics. We wanted to understand what barriers prevent medical students from applying to dermatology and whether these barriers differed based on students' racial, ethnic or socioeconomic backgrounds. The main findings of this study are that certain groups are more likely to cite specific barriers than non-minority students. These barriers are significant deterrents to applying to dermatology and include the lack of diversity in dermatology, negative perceptions of minority students by residency programs, socioeconomic barriers such as lack of loan forgiveness and poor accessibility to mentors.  (more…)

MM: Scabies is extremely common. Globally in the region of 100-200 million people are believed to be affected by scabies annually. Recently the WHO has recognised Scabies as a ‘Neglected Tropical Disease’ in response to this burden of disease. There has been increasing interest in using Mass Drug Administration (treating whole communities) as a strategy to control scabies in communities. In order to make this practical countries need an easy mechanism for establishing if scabies is a significant problem in their communities. In general when treating an individual, clinicians would conduct a full body examination to diagnose scabies – however this may not be practical or necessary when making decisions about whether to treat whole communities. DE: Despite the fact that Scabies is a very common condition that causes a great deal of health problems, it has been largely neglected by health, research and funding agencies – but pleasingly, the WHO has now started to take action on scabies control, starting with the recognition of scabies as a "Neglected Tropical Disease" (more…)
Author Interviews, Dermatology, JAMA, NYU / 19.12.2018

MedicalResearch.com Interview with: Nicholas A. Soter, MD The Ronald O. Perelman Department of Dermatology New York University School of Medicine New York, New York MedicalResearch.com: What is the background for this study? Response: Nearly 50% of patients with chronic spontaneous urticarial (CSU) (hives) incompletely respond to first-line therapy with H-1 antihistamines. However, in the current literature, there is limited evidence to guide the treatment of CSU after maximal therapy with antihistamines fails.  Two small, randomized, controlled trials suggest that dapsone, which is an antimicrobial therapeutic agent with anti-inflammatory properties, may be a useful second-line therapeutic agent.

MedicalResearch.com Interview with: Dr. Kristine A. Romine MD CEO and Founder of Camelback Dermatology & Skin Surgery Phoenix, AZ MedicalResearch.com: Would you give a brief overview of the different types of skin cancer? Response: There are multiple types of skin cancer, including: melanoma, basal cell carcinoma, squamous cell carcinoma, and actinic keratosis. Known as the deadliest form of skin cancer, melanoma develops when irreparable DNA damage results in malignant transformation of melanocytes. This type of skin cancer is most commonly caused by intense UV exposure from the sun or tanning beds, which activate mutations that lead skin cells to rapidly multiply and form malignant tumors. Melanoma can range in color from dark brown to black and are rarely red or even skin colored. They are usually irregular and asymmetrical. In 2018, there were an estimated 91,270 new cases of melanoma (American Cancer Society, 2018). Basal cell carcinoma (BCC) is the most common type of skin cancer and cancer diagnosed. BCCs arise in the skins’ outermost layers. BCCs resemble open sores, red or pink plaques, pearly nodules with telangiectasia, or scars. It is estimated that 4.3 million BCCs are diagnosed in the U.S. every year (Skin Cancer Foundation, 2018). Squamous cell carcinoma (SCC), the second most common type of skin cancer, arises from the squamous cells in the skin that have been exposed to UV over long periods of time. SCCs appear as scaly red or pink macules, papules, or plaques. They can be crusted and appear eroded and can commonly arise within a solar keratosis. More than 1 million cases of SCC are diagnosed in the U.S. every year (Skin Cancer Foundation, 2018). Lastly, actinic keratoses (AKs) are the most common pre-cancerous skin growth that can develop into a SCC if left untreated. Similar to all other types, AKs are caused by exposure to UV light and, in rare cases, high exposures to x-rays. AKs can appear on sun-exposed areas, including the face, scalp, ears, shoulders, and legs. They resemble pink, scaly rough patches on the skin. (more…)
Author Interviews, Dermatology, Lipids / 04.12.2018

MedicalResearch.com Interview with: Wendy Bollag, PhD, FAHA Professor of Physiology VA Research Career Scientist Augusta University, Georgia MedicalResearch.com: What is the background for this study? Response: We have previously shown that the lipid (fat) phosphatidylglycerol (PG) is able to inhibit rapidly growing keratinocytes (skin cells) and promote their maturation. We also found that PG can suppress skin inflammation. Since the common skin disease psoriasis is characterized by inflammation and excessive growth and abnormal maturation of skin cells, we believed that PG might be useful as a treatment. However, the mechanism of its anti-inflammatory effect was unknown. PG in the lung has been found to inhibit inflammation induced by microbes or their components, which work by activating the innate immune system via binding to proteins called toll-like receptors (TLRs); however, psoriasis is not considered to be an infectious disease. We hypothesized that PG would also inhibit inflammation induced by anti-microbial peptides that activate TLRs. Anti-microbial peptides, produced normally by the skin to protect against infection, are known to be excessively up-regulated in psoriatic skin.  (more…)

MedicalResearch.com Interview with: Philipp Tschandl, MD PhD, Priv.Doz. Assistant Professor Department of Dermatology Medical University of Vienna MedicalResearch.com: What is the background for this study? What are the main findings? Response: Dermatoscopy is a non-invasive imaging technique, where the surface of the skin is rendered translucent and additional important morphologic features become visible from deeper layers. This is achieved through use of immersion fluid or cross-polarised light - equivalent to the effect when using a pair of goggles to look underwater, or polarised sunglasses to reduce glare on glass surfaces. After the first description of “Dermatoskopie" almost 100 years ago by a German dermatologist (Johann Saphier), this technique has evolved to a successful, low-cost, state-of-the-art technique for clinical skin cancer detection in the last decades. Convolutional neural networks (“CNN”) are powerful machine learning methods, and frequently applied to medical image data in the recent scientific literature. They are highly accurate for basic image classification tasks in experimental settings, and found to be as good as dermatologists in melanoma recognition on clinical or dermatoscopic images. In this study we trained a CNN to diagnose non-pigmented skin lesions (where melanomas are only a minority) through analysis of digital images, and compared the accuracy to >90 human readers including 62 board-certified dermatologists. This study expands knowledge in the following ways compared to previous work: - We applied the network for the detection of non-pigmented skin cancer, which is far more common in the (caucasian) population than melanoma. - We created a prediction model that combines analysis of a dermatoscopic and clinical image (“cCNN”) which is able to further increase diagnostic accuracy. - We compared accuracy not only to experts, but users with different level of experience (more…)
Author Interviews, Dermatology, JAMA / 26.11.2018

MedicalResearch.com Interview with: Dr Tarun Narang MD MNAMS Department of Dermatology, Venereology, and Leprology Postgraduate Institute of Medical Education and Research Chandigarh, India MedicalResearch.com: What is the background for this study? Response: Acne is one of the most common dermatological problem for which the patients seek medical care. Post acne scarring is a complication of acne, resulting in long lasting physical disfigurement and low self esteem in the affected individuals. Even though there are various methods like microneedling, chemical peeling, cryorolling and ablative lasers to address the post acne atrophic scarring, these procedures are office based hence physician dependent. A home based treatment modality that can treat post acne atrophic scarring with a comparable efficacy to the procedural modalities of treatment will be beneficial to the patient. Our study was done to assess the efficacy of a topical modality of treatment, tazarotene gel, 0.1% in the management of post acne atrophic scarring in comparison to an established method, the microneedling.

MedicalResearch.com Interview with: Christopher S. Lee, PhD, RN, FAHA, FAAN, FHFSA Professor and Associate Dean for Research Boston College William F. Connell School of Nursing Chestnut Hill, MA 02467 MedicalResearch.com: What is the background for this study? Response: Although the efficacy of omalizumab (i.e. can it work?) in the treatment of chronic idiopathic (spontaneous) urticaria has been established in clinical trials, the effectiveness of omalziumab (i.e. does it work?) in the real-world management is less well established. The purpose of this study was to synthesize what is known about the benefits and harms of omalizumab as used in real-world treatment of Chronic Idiopathic (Spontaneous) Urticaria. (more…)

What are the main findings? Response: Previous studies have shown common genotypes, clinical course, and immunological features shared by psoriasis and inflammatory bowel disease. However, the relationship between psoriasis and inflammatory bowel disease was largely unclear. In this study, we found when compared to the general population, psoriatic patients are more likely to have concomitant inflammatory bowel disease.  (more…)

MedicalResearch.com Interview with: Dr. Janet Prystowsky, MD Dr. Prystowsky is a leading board-certified dermatologist in New York City.   In addition to her private practice, Dr. Prystowsky is a senior attending physician at Mount Sinai Roosevelt/St. Luke’s Medical Center. http://www.janetprystowskymd.com/ MedicalResearch.com: When does sun damage to the skin start?  Is there such a thing as a 'safe tan'?  Who is most susceptible to photoaging?  What parts of the body are more likely to show signs of sun damage?  Response: Sun damage will increase a person’s risk of premature aging and skin cancer.  Although tanning does function to help protect your skin from excessive ultraviolet radiation tanning is still a form of sun damage.  Also, people with very fair skin may not tan at all; only burn.  They are the most susceptible to sun damage. Certain medical conditions (e.g., Lupus), medications, cosmetics, and food can make your more reactive (photosensitive) to sunlight. "Sunburn" by Kelly Sue DeConnick is licensed under CC BY-SA 2.0Sunburns are caused by UV damage from sun rays, almost entirely due to UVB rays. UVA rays are weaker for burning but can contribute to blistering sunburns as well. For example, If you get lime peel rubbed on your skin while you are in the sun, you could get a bad burn.  UVA can also cause significant skin damage that can result in premature wrinkling, brown spots, and skin cancer. That's why you'll see dermatologists pushing for broad-spectrum sunscreens as opposed to sunscreens that just protect against UVB rays.  (more…)

MedicalResearch.com Interview with: foamixDavid Domzalski CEO Foamix Pharmaceuticals MedicalResearch.com: What is the background for this study?  How does FMX101 differ from other treatment for acne, ie benzoyl peroxide, topical clindamycin etc?  Response: This study measures the safety and efficacy of a topical foam formulation of the antibiotic minocycline, for the treatment of moderate-to-severe acne. Minocycline is one of the most commonly used products for the treatment of acne, but is currently only available in an oral dosage form. Significant side effects are associated with oral minocycline, including GI upset, photosensitivity, headaches, dizziness, and other potential effects on the CNS.  In addition to the side effects associated with oral minocycline, many currently available topical acne medications contain ingredients which can be drying and irritating to the skin.  These side effects can be frustrating to patients and potentially impact overall compliance to their treatment regimen.  The study addresses important unmet needs in dermatology to determine whether providing patients with a topical dosage form of minocycline may have potential advantages over existing products. In our first two Phase 3 clinical studies, >95% of facial local tolerability signs and symptoms were classified as “none” or “mild,” including dryness, erythema and itching.  Also, our topical minocycline foam, FMX101, is a natural triglyceride-based vehicle that does not contain ingredients that serve as  primary irritants or surfactants.  We believe that FMX101, if approved, would be the first topical minocycline available for the treatment of acne and provide a novel and much needed treatment option for patients who suffer from the physical and psycho-social effects of acne.

MedicalResearch.com Interview with: Raghav Tripathi, MPH Case Western Reserve University MD Candidate, Class of 2021 MedicalResearch.com: Why did you decide to perform this study? Response: Differences in the impact of dermatologic conditions on different groups have been of interest to our research group for a long time. Previously, our group had found differences in time to treatment for patients with different skin cancers. Beyond this, we had found differences in mortality and incidence of various skin conditions (controlling for other factors) in different racial groups/ethnicities, socioeconomic groups, demographic groups, and across the rural-urban continuum. The goal of this study was to investigate socioeconomic and demographic differences in utilization of outpatient dermatologic care across the United States. As demographics throughout the country become more diverse, understanding differences in utilization of dermatologic care is integral to developing policy approaches to increasing access to care across the country.  (more…)
Author Interviews, Dermatology, Eli Lilly / 25.09.2018

MedicalResearch.com Interview with: Lotus Mallbris, M.D., Ph.D., Vice president, Immunology Development Lilly Bio-Medicines  MedicalResearch.com: What is the background for this study? What are the main findings? Response: By exploring creative clinical approaches and patient-centric pathways to more thoroughly address the key aspects of treating these complex conditions, Lilly is bringing innovation forward in hopes of reducing the burden of dermatologic disease for people around the world. The results of the IXORA-S study suggest that Taltz may provide significantly greater clearance of nail psoriasis than ustekinumab. This is significant because nail lesions are a common feature of psoriasis. It’s often associated with discomfort, which can lead to functional impairment and distress, further supporting the importance of complete clearance.   (more…)
