19 Sep Hidradenitis Suppurativa Linked To Increased Risk of Metabolic Syndrome
MedicalResearch.com Interview : Iben Marie Miller, MD Department of Dermatology Roskilde Hospital, Roskilde Department of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark Medical Research: What are the main findings of the study? Dr. Miller: Using a cross-sectional design based on data from a Hidradenitis Suppurativa (HS) group recruited from the hospital (32 individuals), an HS group recruited from the general population (326 individuals) and 14,851 individuals without Hidradenitis Suppurativa, we investigated a possible association of Hidradenitis Suppurativa and the metabolic syndrome. We found that the HS groups had 2 to 4 times odds of having the metabolic syndrome when compared to individuals without HS leaving Hidradenitis Suppurativa patients at a high cardiovascular risk. Furthermore, we found that the odds were higher for the HS group from the hospital in comparison to the Hidradenitis Suppurativa group from the general population.11 Sep Study Examines Risk of Alopecia Areata and Vitiligo in Stem Cell Recipients
MedicalResearch.com Interview with: Rena Zuo, BA MD Candidate at Duke University School of Medicine and Edward W. Cowen, MD, MHSc Senior Clinician Head, Dermatology Consultation Service Dermatology Branch Center for Cancer Research National Cancer Institute National Institutes of Health MedicalResearch: What are the main findings of the study? Answer: Chronic graft-vs-host disease (cGVHD) is a debilitating multisystem disease that occurs in patients receiving allogeneic hematopoietic stem cell transplantations as treatment for hematologic disorders. Although the diverse clinical presentations of cGVHD frequently mimic other autoimmune diseases such as Sjögren syndrome and systemic sclerosis, and low-titer antibodies are commonly found in patients with cGVHD, the exact pathogenesis and role of autoimmunity in cGVHD are incompletely understood. Our study is the first to characterize and identify risk factors associated with the development of two uncommon autoimmune phenomena, specifically alopecia areata and vitiligo, in the setting of cGVHD. Laboratory markers, including 11 antibodies, transplant-related factors, and other cGVHD systemic manifestations were analyzed. Several particularly interesting results were found:- Among 282 patients with cGVHD, 15 demonstrated vitiligo (14 of 282; 4.9%) and/or alopecia areata (2 of 282; 0.7%).
- Female donor and female donor to male recipient sex mismatch, in particular, are significantly associated with the development of vitiligo and/or alopecia areata.
- Positive anti-cardiolipin (ACA) IgG was also significantly associated with development of vitiligo and/or alopecia areata.
11 Sep Isotretinoin Associated With Lower Risk of Inflammatory Bowel Disease
MedicalResearch.com Interview with:
Shadi Rashtak, MD
Department of Dermatology
Mayo Clinic College of Medicine
Rochester, Minnesota
Medical Research: What are the main findings of the study?
Dr. Rashtak: We found that among a population of mainly acne patients those who received isotretinoin had a lower risk of inflammatory bowel disease as compared to those who did not take this medication. We carefully reviewed the medical records of patients to ensure that this finding was not simply because the drug was avoided in patients with a previous personal or family history of IBD.
28 Aug Photodynamic Therapy Removed More Actinic Keratoses Than Cryotherapy
MedicalResearch.com Interview with:
Gayatri Patel, MD, MPH
Division of General Medicine
UC Davis Medical Center
Medical Research: What are the main findings of the study?
Dr. Patel: In this systematic review and meta-analysis, we sought to determine the effectiveness of photodynamic therapy (PDT) for the treatment of actinic keratoses relative to other common treatments. We included only randomized controlled trials and preformed a meta-analysis on homogenous studies. The primary finding of the study was that PDT has a better chance of removing actinic keratoses on the face or scalp than treatment with cryotherapy.
06 Aug Genetic Variant Linked To Severe Skin Reaction To Seizure Medication
upcoming JAMA publication:
MedicalResearch.com Interview with:
Shuen-Iu Hung, PhD, for the Taiwan SCAR consortium
Associate Professor, Department of Pharmacology,
National Yang-Ming University, Taipei, 112 Taiwan
Medical Research: What are the main findings of the study?
Reply: Phenytoin, a widely prescribed antiepileptic drug, can cause severe cutaneous adverse reactions (SCAR) (e.g., Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) ), which carry high mortality and morbidity. The genomic basis of phenytoin-induced SCAR has not been known. This study identifies CYP2C variants, including CYP2C9*3 known to reduce drug clearance, as the key genetic factors associated with phenytoin-related severe cutaneous adverse reactions. These findings have potential to improve the safety profile of phenytoin in clinical practice and offer the possibility of prospective testing for preventing phenytoin-related SCAR.
05 Aug Should You Get Botox From A Nurse, Dermatologist or Plastic Surgeon?
MedicalResearch.com Interview with:
Henry M. Spinelli, MD, PC
Plastic & Reconstructive Surgery
875 Fifth Avenue
New York, NY 10065
Medical Research: What are the main findings of the study?
Dr. Spinelli: Briefly, we polled approximately 26,000 plastic surgeons by way of membership in the International Society of Aesthetic Plastic Surgeons (ISAPS), American Society for Aesthetic Plastic Surgery (ASAPS) and American Society of Plastic Surgeons (ASPS) and collated this data and published it in Aesthetic Plastic Surgery (the Blue Journal), the official journal of ISAPS. This preliminary study was initiated given the current and past healthcare and cosmetic medical/surgical care climate both in the United States and worldwide. As a background, when it comes to injectables (botox and fillers) there is not a united consensus on a state by state basis in the USA and from country to country worldwide. Additionally, the regulations and laws governing the administration of botox and injectables is in a constant flux. For instance, the UK allowed beauticians in the past to administer these substances however they are now banned from legal administration of these products. Alabama, only allows physicians (dermatologists and plastic surgeons) to purchase and administer botox and injectables whereas the medical board of California states that physicians can perform the procedure or oversee licensed registered nurses, licensed vocational nurses, or physicians assistants. Similarly, dentists in some states are permitted to administer these agents. It would be a bad idea for any physician working with botox to take Advanced Botox Training to reduce the possibility of medical misdemeanors.
At the present time few studies have directly assessed the capability of various providers to administer cosmetic injections. When people schedule a consultation for plastic surgery, they are often looking for things like a younger face or a nicer body. The answer to the previous question will become more important as the demand for these procedures continues to grow and an increasing number of practitioners and different Plastic Surgeon from a variety of backgrounds enter the field to meet demand. This study aimed to help define the role of various practitioners in an increasingly more competitive environment for injectables and to explore the relationship between patient and injectable provider in order to improve patient satisfaction and outcomes.
When asked to rank patients’ perceptions of various providers according to their expertise in administering Botox and dermal fillers, responders ranked plastic surgeons and dermatologists as most capable (96%) then nurses in plastic surgery and dermatology (3%). Gynecologists (<1%), dentists (<1%) and nurses in other fields (<1%) all received nearly equivalent numbers of “most capable” rankings. When asked to rank patients’ perception of various providers according to their inability to administer Botox and dermal fillers, nurses in other fields were most frequently ranks as least capable (63%) followed by dentists (26%), gynecologists (12%), plastic surgeons and dermatologists (2%) and nurses in plastic surgery and dermatology (1%).
01 Aug Do Dermatologists Find Thinner Melanomas?
MedicalResearch.com Interview with: Estee L. Williams, MD SUNY Downstate Medical Center, Brooklyn, New York Madfes Integrated Dermatology, New York, New York williams.estee@gmail.com Medical Research: What are the main findings of the study? Dr. Williams: In our retrospective review of all melanomas diagnosed at the Veterans’ Affairs Hospital in Brooklyn since 2000, we discovered that although a majority of the melanomas (63%) were found by the dermatologist during a yearly “full body” screening examination (versus detection by the patient), melanomas found by the dermatologist were not necessarily thinner (hence, earlier, more curable) than those found by the patient.23 Jul Psoriasis May Increase Risk of Atherosclerosis
MedicalResearch.com Interview with:
Reza Robati, MD
Associate Professor of Dermatology
Deputy editor, Iranian Journal of Dermatology
Skin Research Center, Shahid Beheshti University of Medical Sciences

Medical Research: What are the main findings of the study?
Dr. Robati: In our study, increased levels of serum leptin and resistin and increased intima-media wall thickness of common carotid artery were observed in 60 psoriasis patients in comparison with 60 healthy controls. Moreover, we found positive correlation between these variables in psoriasis patients.
25 Jun Keloids: Using Drug-Eluting Microneedles To Allow Self Treatment
MedicalResearch.com Interview with Chenjie Xu PhD Assistant Professor of Bioengineering Nanyang Technological University Singapore 637457 MedicalResearch: What are the main findings of the study? Answer: Keloid is a long-term dermatological scarring disease characterized by disfiguring lesions resulting from overgrowth of dense fibrous tissue. It is also unsightly and can even lead to disfigurement and psychological problems of affected patients. This study investigated the use of microneedle technology in the self-management of keloid lesions. Briefly, we have developed a “wearable” microneedle device for transdermal delivery of an anti-metabolite drug (5-FU) to inhibit the proliferation activity of keloid fibroblast. This study has provided evidence for effective inhibition of keloid fibroblasts in vitro and successful translation of this platform can significantly reduce the cost of keloid treatment and improve the patient compliance.26 May New Antibody Can Block Pain and Itch Simultaneously
MedicalResearch.com Interview with:
Seok-Yong Lee, Ph.D.
Assistant Professor of Biochemistry and
Ru-Rong Ji, Ph.D.
Distinguished Professor of Duke University
Professor of Anesthesiology and Neurobiology
Chief of Pain Research
Duke University Medical Center
Durham, NC 27710
MedicalResearch: What are the main findings of the study?
Answer: We have developed an antibody that can block the pain and itching sensations in mice simultaneously with high efficacy. We would like to point out that our discovery has the potential to be applied to human once the antibody is humanized. Given the high selectivity, general safety profile, and long half-lives of monoclonal antibodies, this method we developed to raise antibodies against therapeutic targets (e.g., ion channels) can have broad applications to other diseases.
02 Apr Fat and Hair Growth Synchronized By Same Signalling Pathway
MedicalResearch.com Interview with:
Professor Rodney Sinclair
University of Melbourne and Epworth Hospital
Melbourne, VIC, Australia
MedicalResearch.com: What are the main findings of the study?
Answer: Activation of Wnt signalling promoted hair growth and fat growth. Inhibition of Wnt signalling reduces fat growth and hair growth. We looked at the fat layer on the scalp. It was reduced by 50% over the bald areas of alopecia areata. The patch of alopecia areata we looked at was new- only appeared a few days earlier and so the changes in fat thickness are rapid.
What is interesting is that the fat layer is dynamic, and significant fluctuations can occur in a rapid period of time in sync with the hair cycle. It is also interesting that ligands for BMP6 and IGF2 are pro-adipogenic.
There are a couple of bigger questions that earlier media reports did not focus on- namely upstream factors regulating the hair cycle clock and the beauty of synchronization of fat and hair growth for seasonal thermal insulation.
13 Feb Teledermatololgy As Triage Tool For Dermatology Hospital Consultation
MedicalResearch.com Interview with:
Dr. Misha A. Rosenbach
Assistant Professor of Dermatology Hospital of the University of Pennsylvania Section Editor,
JAMA Dermatology Patient Page
MedicalResearch.com: What are the main findings of the study? Dr. Rosenbach: There is strong agreement between teledermatologists and in-person dermatologists when evaluating inpatients at a tertiary care academic hospital. The primary aim of this study was to assess telederm as a triage tool. Many dermatologists are not full-time hospitalists, but work in private practice or clinics which may be remote from affiliated hospitals. The goal was to evaluate whether teledermatology could help those providers assess the acuity of inpatient consults. There was strong concordance.
05 Feb Pregnancy Exposure to Colds, Dust Mites and Offspring Atopic Dermatitis, Hayfever
MedicalResearch.com Interview with:
Dr. Sabina Illi, Dipl.-Stat., MPH
University Children's Hospital
Lindwurmstr. 4
80337 Munich Germany
MedicalResearch.com: What are the main findings of the study?
Answer: We observed that the offspring of atopic pregnant women that showed symptoms of atopy during pregnancy, i.e. atopic dermatitis or hay fever, had a higher risk of having the respective atopic disorder themselves. However, we do not know whether this is due to timing, i.e. pregnancy, or whether it merely mirrors the severity of maternal disease.
Furthermore, in our study pregnant mothers with repeated colds during pregnancy were at increased risk of having a child that wheezed at pre-school age, this was statistically independent of the intake of medication.
23 Aug Stretch Marks: Four Genetic Markers Near Elastin Gene Identified
MedicalResearch.com Interview with:
Joyce Y Tung Ph.D.
Research Team
23andMe Inc.
Mountain View, California, USA
MedicalResearch.com: What are the main findings of the study?
Dr. Tung: 23andMe researchers identified four genetic markers that were significantly associated with the development of stretch marks, including one near the elastin (ELN) gene. This finding may further explain why some individuals are more susceptible to the skin condition. Given that loose skin is a symptom of syndromes caused by deletion or loss-of-function mutations in ELN, these results also support the hypothesis that variations in the elastic fiber component of the skin extracellular matrix contribute to the development of stretch marks.
