Second-line therapies for AD should be used in recalcitrant cases or in patients with uncontrolled disease despite compliance with first-line measures and avoidance of allergens. Recommended advanced therapies include phototherapy, especially narrowband ultraviolet B, systemic immunosuppressants, and a new biologic agent. Few studies have compared head-to-head efficacy of the different immunosuppressant therapies such as cyclosporine, methotrexate, azathioprine and mycophenolate mofetil. Therefore, the agent used is based on provider and patient preferences and can be decided on a case-by-case basis.

As a result, AD can be complicated by irritant and allergic contact dermatitis and imbalances in the skin microbiome, which can subsequently exacerbate the severity and complicate the course of preexisting atopic disease. Itch is an important symptom of AD, as it plays a large role in the quality of life of patients and their families. Since AD is a chronic, inflammatory disease that recrudesces throughout life, many have utilized alternative and/or complementary therapies, as monotherapy or in conjunction with conventional therapies, as a form of management.

AD therapies attempt to correct this pathology, and guidelines suggest suggest basics of AD therapy, which include repair of the skin barrier through bathing practices and moisturizers, infection control, and further lifestyle modifications to avoid and reduce AD triggers.While some patients' AD may be controlled using these measures, inflammatory eczema including acute flares and maintenance therapy in more severe patients are treated with topical pharmacologic agents such as topical corticosteroids, topical calcineurin inhibitors, and, more recently, topical PDE-4 inhibitors. This model of basic skin therapy and, as needed, topical pharmacologic agents may be used to treat the vast majority of patients with AD and remains the staple of AD therapy.

Arising from a complex interplay between environmental and genetic factors, the definitive etiology of AD is perplexing and controversial. Advances in molecular medicine are radically transforming our understanding of AD pathogenesis. Increasing knowledge on the pathogenesis of AD results in novel therapeutic targets and pathways. This article details the pathogenesis section of the Curriculum United for Better Eczema Care (CUBE-C), facilitating primary care and sub-specialist education on the scientific advances driving recent AD therapeutic innovations.

The central diagnostic features of AD include pruritus, xerosis, eczematous lesions with a characteristic morphology and distribution, and a personal or family history of atopic disease. Several clinical studies have emphasized the link between AD and other atopic disorders including asthma, allergic rhinitis, and food allergies. More recent studies indicate possible links between AD and other nonatopic disorders, including ADHD, sleep disturbance, and mental health disorders, suggesting an even more profound impact of this disease. Furthermore, the social, emotional, and personal impact of AD for patients and their caregivers is substantial. Understanding both the clinical characteristics and implications of AD is critical to lessening the psychosocial, clinical, and economic burden of this disease.

Moreover, standardized treatment protocols that incorporate upcoming eczema therapies and emerging guidelines have yet to be established. Thus, there is both a need and an opportunity to equip clinicians to succeed in this novel and changing era of eczema care. The National Eczema Association's (NEA) strategic plan-developed through extensive discussions with patients who have atopic dermatitis and their caregivers, industry, and providers representing different specialties-called for the creation of an interdisciplinary coalition to steer this initiative. The Coalition United for Better Eczema Care (CUBE-C) is a network of cross-specialty leaders working to help construct an educational curriculum based on standards of effective treatment and disease management.

This educational supplement summarizes the highlights of clinical sessions presented during this CME/CE conference. A growing understanding of the biology of psoriasis has facilitated the development of increasingly efficacious medications. Skin clearance used to be regarded as an impractical goal for psoriasis therapy. Now, some clinical trials of newer medications report more than half of participants attaining Psoriasis Area and Severity Index (PASI) scores of 90. Two leading investigators review the latest findings about the treatment of this condition. Recent evidence demonstrates that psoriasis and psoriatic arthritis share multiple pathological underpinnings. A T helper type 17 (Th17) lymphocyte-based pathogenesis, genes, and microbiome changes have been identified in both conditions. Many therapeutics used in psoriasis care are efficacious in psoriatic arthritis. An expert in psoriatic arthritis updates readers about this condition. Cutaneous fungal infections, including onychomycosis, pose diagnostic and treatment challenges. New topical therapies and an investigational oral agent offer expanded options for management. The American Academy of Dermatology has issued new guidelines for the treatment of acne. Appropriate antibiotic use is a prominent theme. The US Food and Drug Administration has issued a communication about the risk of unintentional injection of soft tissue fillers into facial blood vessels-including blindness. The lead author of a recent review about this topic discusses how to prevent this serious outcome. The volume of new information about pathophysiology, diagnosis, therapy, and safety challenges our ability to keep current while enabling us to improve patient care. We hope that the highlights of this seminar offer you information that can be applied to your busy practices.

Several new topical medications have been developed that target the enzyme PDE; crisaborole was recently approved by the US Food and Drug Administration (FDA) for the treatment of atopic dermatitis, and phase II studies have been completed on OPA-15406. The phase III clinical trial results of the systemic medication dupilumab, an inhibitor of the IL-4 receptor α subunit (which inhibits both IL-4 and IL-13 signaling), are currently being reviewed by the FDA.

In addition, flares can be effectively controlled and, in some cases, prevented. New topical medications, improved strategies for the use of topical corticosteroids and topical calcineurin inhibitors, and judicious use of nonpharmacologic regimens-including bathing, bleach baths, and early use of emollients-have led to better disease management and improved quality of life for patients and their families.

Recent studies also have demonstrated that a simple intervention from birth-the daily application of an emollient moisturizer-seems to protect susceptible infants from the development of AD.

The diagnosis usually can be reliably established on the basis of the history and physical examination. In patients with skin of color, blanching of the skin may be helpful to detect erythema, lichenification, follicular accentuation, and hypopigmentation (all of which are more common than in lighter-skinned patients). Once the diagnosis of AD is established, an assessment of severity, persistence, and impact on the patient's and family's life is important as a guide to treatment decisions.

The disease is poorly understood and treatment is not satisfactory. In October 2016, the Canadian and United States Hidradenitis Suppurativa Foundations organized the inaugural Symposium on Hidradenitis Suppurativa Advances (SHSA) in Toronto, Canada. This meeting brought together experts from Canada, the United States, and Europe to discuss the latest advances in HS. After this important event, we considered that it would be helpful to outline current HS knowledge and to identify important gaps in treatment and research in order to move forward more efficiently. This paper briefly summarizes current knowledge in key areas including epidemiology, clinical presentation and morphological classification, natural history and prognosis, genotype-phenotype correlations, clinico-pathological correlation, pathogenesis, optimal treatment and outcome measures. General and initial suggestions for addressing these gaps are presented.

Repeated episodes of profound inflammation in HS can lead to a number of complications, causing significant morbidity and decreasing quality of life. Complications of HS may affect the skin alone or may have systemic impact. Cutaneous complications of HS include sinus tracts, fistulae, scarring and contractures, squamous cell carcinoma, and lymphedema. Systemic complications of HS include chronic pain, systemic amyloidosis, and possibly anemia. Preventing disease complications by controlling primary disease is a key component of HS management. Clinicians should be prepared to recognize complications early, as prompt management is necessary to minimize negative impacts.

The inflamed lesions progressing to noninflamed nodules and abscesses are not only perceived as unclean and stigmatizing by the patients, but also cause pain and scarring making this inflammatory skin disorder unique. It is obvious that the disease has a significant negative impact on the patients' quality of life (QOL). The impact is influenced not only by the pain which is a significant independent contributor to the patients' life quality, but by the clinically significant comorbidity associated with HS. In particular, the psychological comorbidities of depression and anxiety both further compound QOL impairment and pain. It is strongly recommended that these factors be taken into account when planning a treatment strategy for patients with HS, and that specific steps are taken to manage pain and comorbidities associated with the reduced QOL generally experienced by this group of patients. Basic pain management includes anti-inflammatory treatments as well as local- and central-acting analgesics. In more complex cases, access to consultations with a pain specialist may be necessary and may require the judicious use of antidepressants. In addition, it is recommended that patients' QOL be addressed specifically through psychological education and patient support groups.

Light and laser therapies have been utilized in the field of dermatology to treat a variety of skin conditions, but more recently were studied in the management of HS. Usually performed as outpatient procedures with a low risk of complications, they offer several advantages to traditional cold knife surgical procedures. We reviewed the various light- and laser-based treatments studied in HS and compared their efficacy. Outcome measures were not standardized, which made comparison difficult. Studies performed were few in number and often limited by small patient samples. Larger, randomized controlled trials that compare these treatment modalities to medical and surgical management are needed. Despite their limitations, light- and laser-based therapies are promising treatment options for patients with refractory HS.

A wide array of therapies has been reported successful in the treatment of hidradenitis, although few high-quality clinical trials have been conducted. Comparing the effectiveness of different therapies has proven challenging due to heterogeneity and limited validation of outcome measures. We performed a systematic review of clinical trials of medical treatments for hidradenitis, yielding 8 articles reporting on 9 trials of antibiotic, hormonal, and biologic therapies. In addition, we discuss existing observational data on commonly used therapeutic regimens, as well as the outcome measures driving clinical research in hidradenitis suppurativa.

HS is a highly distressing condition, and has one of the highest impacts on quality of life compared to other dermatologic diseases. Various topical therapies have been described that may be used alone or in conjunction with systemic or physical modalities for HS. Additionally, proper wound care is essential to the successful management of HS, particularly given the suppurative nature of the disease. However, limited evidence exists regarding the optimal regimen for topical therapy and wound care. On the basis of existing literature, we provide a comprehensive review of topical management and wound care.

In addition, HS patients can suffer from a variety of diseases related to the chronic inflammatory nature of their HS such as cardiovascular disease and anemia. An understanding of these comorbidities and associations is essential for the management of HS, and routine screening for these entities should be considered in all HS patients.

Some of our knowledge comes from clinical and epidemiological observations, along with studies of the histopathology and immunohistochemistry of affected skin. More recently, cutaneous molecular studies and transcriptomic analyses have provided additional information regarding inflammatory processes. The chronic cutaneous inflammation, systemic symptoms, and associated comorbidities suggest that HS should be classified as an immune-mediated disease, rather than a primary infectious disease. As such, a proposed integrated disease pathway is presented. At a fundamental level, there appears to be a primary abnormality in the pilosebaceous-apocrine unit, which leads to follicular occlusion, perifollicular cyst development that traps commensal microbes, and rupture into the dermis. This can trigger an exaggerated response of the cutaneous innate immune system. Initially this is an acute event, but ongoing intermittent disease activity can lead to recurrent inflammatory nodules and dermal tunnels. Once underway, the cutaneous inflammation is very difficult to turn off, leading to suppurative inflammation in whole anatomic regions. As the disease progresses, we propose that there is recruitment of the systemic immune system perpetuating the chronic cutaneous inflammatory process. There remains much to be done to understand the pathogenesis and immune signature of this challenging disease.
