The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) Celebrates Its 20th Anniversary.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) started in August 2003 with 40 initial participants and celebrated its 20th anniversary with 1036 members, many of whom attended the annual meeting in Dublin, Ireland, on July 15 to 17, 2023. GRAPPA arose from a need experienced by psoriatic arthritis (PsA) and psoriasis (PsO) investigators to meet to address questions related to psoriatic disease (PsD). Though other groups were meeting at the time to classify and discuss PsA, GRAPPA arose from a desire to include international clinical and investigational researchers of both dermatology and rheumatology. The organization has built awareness of PsO and PsA, developed and validated research assessment tools to measure clinical status and disease outcomes, published multiple treatment recommendations, supported basic and clinical research on PsD pathophysiology, fostered interactions across research fields, and educated the future generation of PsO and PsA researchers. The group continues to focus on major priorities affecting patients with PsD and will continue evolving in the next decades.

Felix von Bärensprung-A Review of His Life and Work on the Occasion of His 200th Birthday.

ABSTRACT: Felix von Bärensprung was a pioneer of dermatopathology. His monograph of 1848, "Contributions to the Anatomy and Pathology of the Human Skin," was one of the first publications on that subject. Von Bärensprung also described and named erythrasma, elucidated the pathogenesis of herpes zoster, contributed a comprehensive review of the history of dermatology in an unfinished textbook of skin diseases, and was coauthor, together with Ferdinand Hebra of Vienna, of one of the most influential clinical atlases in the history of dermatology. The 200th anniversary of his birthday in 2022 provides an occasion for reminding of one of the leading dermatologists of the mid 19th century.

Alibert and His Contribution to Dermatology (1768-1837).

ABSTRACT: Jean Louis Marc Alibert, 1786-1837, France, is considered one of the founders of modern dermatology, he was able to organize the Hôpital Saint Louis in Paris and developed a school, among other contributions he wrote at least two books, he described the tumoral stage of mycosis fungoides, congenital nevus, keloids, and proposed The Tree of Dermatoses as his concept for the understanding of skin diseases.

Role of phototherapy in the era of biologics.

Phototherapy is a safe and effective treatment for many dermatologic conditions. With the advent of novel biologics and small molecule inhibitors, it is important to critically evaluate the role of phototherapy in dermatology. Surveys have shown that many dermatology residency programs do not dedicate time to teaching residents how to prescribe or administer phototherapy. Limitations of phototherapy include access to a center, time required for treatments, and insurance approval. Home phototherapy, a viable option, is also underused. However, it should be emphasized that modern phototherapy has been in use for over 40 years, has an excellent safety profile, and does not require laboratory monitoring. It can be safely combined with many other treatment modalities, including biologics and small molecule inhibitors. In addition, phototherapy costs significantly less than these novel agents. Dermatologists are the only group of physicians who have the expertise and proper training to deliver this treatment modality to our patients. Therefore, to continue to deliver high-quality, cost-effective care, it is imperative that phototherapy be maintained as an integral part of the dermatology treatment armamentarium.

A "hair-raising" history of alopecia areata.

A 3500-year-old papyrus from ancient Egypt provides a list of treatments for many diseases including "bite hair loss," most likely alopecia areata (AA). The treatment of AA remained largely unchanged for over 1500 years. In 30 CE, Celsus described AA presenting as scalp alopecia in spots or the "windings of a snake" and suggested treatment with caustic compounds and scarification. The first "modern" description of AA came in 1813, though treatment still largely employed caustic agents. From the mid-19th century onwards, various hypotheses of AA development were put forward including infectious microbes (1843), nerve defects (1858), physical trauma and psychological stress (1881), focal inflammation (1891), diseased teeth (1902), toxins (1912) and endocrine disorders (1913). The 1950s brought new treatment developments with the first use of corticosteroid compounds (1952), and the first suggestion that AA was an autoimmune disease (1958). Research progressively shifted towards identifying hair follicle-specific autoantibodies (1995). The potential role of lymphocytes in AA was made implicit with immunohistological studies (1980s). However, studies confirming their functional role were not published until the development of rodent models (1990s). Genetic studies, particularly genome-wide association studies, have now come to the forefront and open up a new era of AA investigation (2000s). Today, AA research is actively focused on genetics, the microbiome, dietary modulators, the role of atopy, immune cell types in AA pathogenesis, primary antigenic targets, mechanisms by which immune cells influence hair growth, and of course the development of new treatments based on these discoveries.

ARTICLE: Colloidal Oatmeal Part I: History, Basic Science, Mechanism of Action, and Clinical Efficacy in the Treatment of Atopic Dermatitis.

Colloidal oatmeal has a long-standing history in the treatment of dermatologic disease. It is composed of various phytochemicals, which contribute to its wide-ranging function and clinical use. It has various mechanisms of action including direct anti-inflammatory, anti-pruritic, anti-oxidant, anti-fungal, pre-biotic, barrier repair properties, and beneficial effects on skin pH. These have been shown to be of particular benefit in the treatment of atopic dermatitis. In Part 1 of this two-part series, we will explore the history of colloidal oatmeal, basic science, mechanism of action, and clinical efficacy in the treatment of atopic dermatitis.

[The dermatologist Edmund Lesser (1852-1918) : Teaching and learning in Leipzig]. / Der Dermatologe Edmund Lesser (1852­1918) : Lehren und Lernen in Leipzig.

Edmund Lesser was one of the most influential German dermatologists of his time. After the death of his academic teacher Oscar Simon in Breslau, the later director of the dermatology hospital at the Charité moved to Leipzig in 1882. At the University of Leipzig he quickly completed his habilitation in June of the same year and continued the course for dermatology and venereology started by Neisser. Later he also went into private practice, where he recruited patients for his lectures. In Leipzig Lesser also published his well-received handbook on skin diseases and venereology and organized the third meeting of the German Society of Dermatology in 1891. Despite his hope and his undisputable achievements, he was not granted professorship by the faculty of medicine in Leipzig. For this he had to become head of dermatology at the University of Bern in 1892. This manuscript deals with his ten important years in Leipzig as a prerequisite for his later merits in Berlin as well as the development of academic dermatology at the University of Leipzig.

Eaux thermales et thermalisme en dermatologie au xixe siècle: Thermal water and hydrotherapy in xixth century dermatology.

Jean-Louis Alibert (1768-1837), Pierre-Alphée Cazenave (1802-1877) and Ferdinand von Hebra (1846-1880) are among the most famous names of the XIXth century dermatology. All were interested in hydrotherapy and mineral waters. Alibert was especially fond of sulfurous waters from the Pyrenees, for treating almost every inflammatory disease, like psoriasis, chronic eczema and even hair diseases or cheloids. He mentioned very often the use of mineral waters in his two masterpieces, Description des Maladies de la peau (1806) and Clinique de l'Hôpital Saint-Louis (1833). In case patients were not able to travel and spend times at thermal stations, he recommended artificial waters made by pharmacists in specialized places in Paris, consisting in water plus minerals, in order to obtain a composition close to natural spring waters. Around 1850, Cazenave also used mineral waters and hydrotherapy, mainly sulfurous waters. In Vienna, von Hebra was more reluctant to the use of mineral water, as he believed that the time spent in baths was more important than the composition of the water itself. Adrien Doyon (1827-1907), who translated Hebra's book in French, strongly disagreed with him, as he had a dermatology private practice in Uriage, in the French Alps. Modern hydrotherapy in dermatology is clearly in relation with this XIXth century tradition. © 2020 Elsevier Masson SAS. All rights reserved.

The diagnosis and classification of amyopathic dermatomyositis: a historical review and assessment of existing criteria.

BACKGROUND: Diagnostic criteria are used to identify a patient having a disease in a clinical setting, whereas classification criteria create a well-defined population for research purposes. The diagnosis and classification of amyopathic dermatomyositis (ADM) have not been recognized by most existing criteria for idiopathic inflammatory myopathies (IIMs). To address this, several criteria were proposed to define ADM either as a distinct disease entity or as a subset of the spectrum of IIMs. OBJECTIVES: To discuss the diagnosis and classification of ADM and to assesses the available criteria in identifying cases of ADM and/or distinguishing it from dermatological mimickers such as lupus erythematosus. METHODS: We conducted an extensive literature search using the PubMed database from June 2016 to August 2018, using the search terms 'amyopathic dermatomyositis', 'diagnosis' and 'classification'. RESULTS: The European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) criteria, which are the only validated classification criteria for adult and juvenile IIM and their major subgroups, include three cutaneous items (Göttron sign, Göttron papules, heliotrope rash) to be able to classify ADM. This international and multispecialty effort is a huge step forward in the classification of skin-predominant disease in dermatomyositis. However, about 25% of the population with ADM do not meet two out of the three skin features and are misdiagnosed or classified as having a different disease entity, most commonly lupus erythematosus. CONCLUSIONS: These gaps rationalize the continuous assessment and improvement of existing criteria and/or the development of validated, separate and skin-focused criteria for DM.

Dermatologic Training and Practice in Canada: A Historical Overview.

The specialty of dermatology is constantly changing to meet the medical needs of our society. The discipline is in flux because of a variety of factors such as growing population needs, technological advancements, fiscal restraint, and demographic changes. As part of an in-depth review of the specialty, the Dermatology Working Group (DWG) for the Royal College of Physicians and Surgeons of Canada sought to determine whether the current training configuration is suitably preparing graduates to meet the societal health needs of dermatology patients. In this first of a 2-part series, the authors conducted comprehensive literature and historical reviews and a jurisdictional analysis to understand the current state of dermatology practice in Canada. Herein, they explore trends in the dermatology workforce, population needs, accessibility, and wait times, as well as issues in undergraduate and postgraduate medical education. In a subsequent publication, the DWG will utilize information gained from this historical analysis and jurisdictional review, stakeholder perspectives, and a national survey to shape the future of dermatology training in Canada.

[Fame alone is not enough : How the renowned discoverer Albert Neisser (1855-1916) came to academic honors in dermatology in Leipzig]. / Ruhm alleine reicht nicht : Wie der gefeierte Entdecker Albert Neisser (1855­1916) in Leipzig zu akademischen Weihen in der Dermatologie kam.

Despite his scientific achievements while still in medical school, Albert Neisser was not accepted into internal medicine. This was typical for this period, as Jewish doctors were not allowed into esteemed disciplines such as internal medicine and surgery. Due to his important discoveries as a resident in dermatology he rose to international fame; however, he had to move to Leipzig to boost his later career in Germany. This step has been somewhat neglected and is therefore the topic of this article.
