Paul L. Bigliardi, MD

Prof. Paul L. Bigliardi, MD is a Physician with over 20 years clinical experiences in Dermato-Allergy focusing on allergic diseases in skin and other epithelia, including diagnostic and management of drug allergies and atopic dermatitis. The training in Dermato-Allergy included a fellowship at the University of Minnesota and a double residency and Swiss board certifications in Dermatology and Allergy/Clinical Immunology in Basel, Switzerland.

From 2005 to 2011 he headed the outpatient clinic and Dermato-Allergy Division at the Department of Dermatology, University of Lausanne, Switzerland. From 2011 to 2018 he led a translational research group at ASTAR Research Institute and a Dermato-Allergy Division at the National University of Singapore. In 2018, he got recruited to the Department of Dermatology, University of Minnesota to create and lead a unique and comprehensive Allergy Division. This Division can diagnose and manage all types of immediate and delayed type allergic reactions, from severe drug allergies to complex atopic diseases to all sort of contact allergies.

In research he is constantly combining his extensive clinical experience with strong collaborations with engineers, biologists, chemists and industry to develop and test new diagnostic and therapeutic models, concepts and devices in skin research and to develop novel human 3D epithelial models.

Session 1: Allergy Testing for Systemic Drug Allergies

Dr. Bigliardi will present on how drug allergies are very common, but most of them are not correctly diagnosed leading to significant morbidity and mortality. He will also cover the following topics:

  • recognize severe drug allergies
  • diagnostic of drug allergies by combination of prick, intradermal and patch tests
  • interpretation of test results

Jonathan M. Spergel, MD PhD

Dr. Jonathan Spergel is a Professor of Pediatrics and holder of Stuart Starr Chair of Pediatrics at the Perelman School of Medicine at University of Pennsylvania and Chief of Allergy Section at Children’s Hospital of Philadelphia and director of Center for Eosinophilic Diseases. He is director of CHOP’s FARE Center of Excellence. His clinical and post-graduate research training in Allergy and Immunology were completed at Children’s Hospital, Harvard Medical School, Boston, MA. Under the mentorship of Dr. Geha, Dr. Spergel developed a murine of model of atopic march and atopic dermatitis. This model has been used for the last 20 years to study multiple atopic diseases including food allergy and Eosinophilic Esophagitis.

Dr. Spergel has worked from bench to bedside working on numerous aspects of food allergy. He has identified genetic risk factors for Eosinophilic Esophagitis and Food allergy. Dr. Spergel identified that food allergy or any allergen can be sensitized through skin in mouse model.

He has held leadership in numerous academic societies including Board of Directors for American Academy of Allergy Asthma and Immunology, Chair of Medical Advisory Board for American Partnership for Eosinophilic Disorders and International Food Protein Enterocolitis Society.

Session 1: Testing for Eosinophilic Esophagitis

Dr. Spergel will answer the question, Can you test for foods in EoE?
In addition, he will cover the following:

  • What is Eosinophilic Esophagitis?
  • What are the triggers for EoE?
  • How can you test for EoE?

Douglas L. Powell, MD

Douglas Powell, MD began his medical career at the University of Utah, followed by a dermatology residency at the University of Rochester where he got his first taste of contact dermatitis and the effects of chemicals on the skin. After residency and a wonderful 4 years of active duty service in the Air Force, Dr. Powell returned to the University of Utah and the mountains that he loves. He then started the contact and occupational dermatitis clinic in the department of Dermatology, which now has been going for 20 years.

He has loved the Sherlockian aspect of the patch test patients and has learned so much through the years from patients, from colleagues and from mentors. Dr. Powell tried at one time to arrange for patch testing in Ghana, Africa. He has a particular interest in contact urticaria which began early in his contact allergy career and which he feels is underappreciated and under evaluated.

Through the years, he has served in a number of positions including: President of Utah Dermatology Society and Intermountain Dermatology Society, 18 years at the 4th Street Homeless Clinic, multiple committees at the ACDS, and is currently the President of the ACDS.

Session 1: Immediate Testing in Patch Clinic

In spite of common knowledge of contact urticaria, it seems that few patch test clinics are evaluating for it regularly for various reasons. Dr. Powell’s lecture will discuss not only the need for its evaluation, but will show simple ways to include it into a typical contact dermatitis practice. He will also cover:

  • The need for the evaluation for contact urticaria regularly
  • Methods for evaluation of contact allergy
  • Simple ways to integrate it into a typical patch test clinic

Dr. Lessin currently serves as Medical Director of KGL Skin Study Center, a Philadelphia-based, independent clinical research facility, that conducts clinical testing of skin care products and drugs/devices in human subjects supporting claims substantiation and regulatory approval.

Dr. Lessin is a one of the co-founders of the Cutaneous Lymphoma Foundation and has served on its Board of Directors and in various capacities since its inception in 1998. He also serves as a member of the Executive Committee of the Dermatology Foundation and has served in various capacities since 1993.

Dr. Lessin and his family live in suburban Philadelphia, PA.

Session 2: Product Safety Patch Testing: Can We Improve Methods?

Dr. Lessin will present on how product safety in patch testing might be improved. In addition, he will cover the following topics:

  • Human repeat insult patch testing (hRIPT) is an established & low risk in-vivo method for assessing safety of topically applied products.
  • hRIPT protocols for contact sensitivity (modified Draize) & cumulative irritation (21-day Cum) are labor intensive with limited detection sensitivity for contact sensitivity.
  • hRIPT for assessing contact sensitivity would benefit from validation & correlation with current non-animal assays.

Mark Denis P. Davis, MD

Dr. Mark Davis is Professor and Chair of the Department of Dermatology at Mayo Clinic Rochester, Minnesota. Born and bred in Ireland, he trained in internal medicine prior to coming to Mayo Clinic in 1991 for a residency in Internal Medicine followed by a residency in Dermatology.

Dr. Davis has broad clinical and research interests. He is the author of 225 peer-reviewed publications, and 30 book chapters. Dr. Davis is especially interested in patch testing and has been director of the patch testing service /Mayo Clinic Contact Dermatitis Group for the past 20 years and has served on the Board of Directors of the American Contact Dermatitis Society. He is looking forward to sharing some thoughts about the conventional wisdom of ignoring the ‘doubtful’ reaction to patch testing materials.

Session 2: The Barely-But-Definitely-There Patch Test Reaction on the Last Reading

Dr. Davis' presentation will cover how reactions to patch test allergens may be subtle but are important, so don’t disregard them!

  • Up to 40% of patch test readings at the final read are graded as ‘macular erythema’- also termed ‘doubtful’ or +/- reactions
  • By convention, these reactions are disregarded by many patch test experts and societies and patients are not educated to avoid these allergens
  • We advocate that these reactions should be assessed just like any other patch test reaction; patients may need to avoid the allergens associated with these reactions for their dermatitis to clear

JiaDe Yu, MD

Dr. Yu is the director of the MGH Contact and Occupational Dermatitis Clinic. He is currently on the Board of Directors for the American Contact Dermatitis Society and is the co-chair of the ACDS Fall Meeting Committee. His research interests focus on allergic contact dermatitis in children.

Session 2: Updates in Pediatric Allergic Contact Dermatitis

Up to 20% of children with atopic dermatitis have concomitant allergic contact dermatitis. This may be missed if patch testing is not performed! Dr. Yu will delve into that, along with:

  • Allergens of high prevalence in children
  • Emerging allergens of important in children

Daniel H. Kaplan, MD PhD

Daniel H. Kaplan, MD PhD is a Professor within the Department of Dermatology and Immunology, University of Pittsburgh. His research is dedicated to understanding the mechanisms that underlie skin immunity and the interplay of different immune cells types that reside in the skin. He has made consistent progress in this area since for approximately 22 years.

As a graduate student at Washington University, St Louis, he participated in the re-invigoration of the concept of tumor immunosurveillance by observing an increased frequency of skin tumors in immunodeficient mice (Kaplan et al, PNAS 1998). During his post-doc at Yale University, he developed a number of mouse lines with a selective deficiency of Langerhans cells (LC) and showed that these cells have the unexpected capacity to suppress tissue immune responses (Kaplan et al. Immunity, 2005). As an Assistant and later Associate Professor at the University of Minnesota, he found that LC and dermal dendritic cells have unique functions in the development of anti-pathogen responses.

More recently, his laboratory has focused understanding how intracellular communication mechanisms between immune cells and non-hematopoietic cells in the skin modulate cutaneous immunity and skin disease. He found that pain-sensing nerves are necessary and sufficient to trigger innate immune responses and this can augment regional immunity by communicating the presence of danger to adjacent areas of skin through a process termed “anticipatory immunity.” Other neurons that innervate the epidermis actively suppress mast cells resulting in attenuated skin inflammation. Finally, his lab has shown that keratinocytes determine LC migration and epidermal residency of resident memory T cells by controlling the amount of available active TGFb in the epidermis.

Keynote Speaker: Sensory Neurons Control Skin Inflammation

Dr. Kaplan will present on how sensory neurons in the skin play an unexpected role in controlling inflammation and will cover the following topics:

  • Inflammation in tissues is driven by cytokine circuits
  • Sensory neurons provide both positive and negative regulation of cytokine circuits
  • Targeting sensory neurons or neurotransmitters to control inflammation is an untapped area with large potential
