Introduction Psoriasis patients demonstrate high interest in the role of diet on their skin condition. However, data are lacking to describe dietary interventions among psoriasis patients and associated outcomes. This study aims to identify common dietary habits, interventions and perceptions among patients with psoriasis, and to examine patient-reported skin outcomes in response to these interventions. Methods We administered a 61-question survey to the National Psoriasis Foundation membership asking psoriasis patients about dietary habits, modifications, skin responses, and perceptions. Results A total of 1206 psoriasis patients responded to the survey. Compared to age- and sex-matched controls, psoriasis patients consumed significantly less sugar, whole grain fiber, dairy, and calcium (p

Author(s): Kazemi, Tiana; Farahnik, Benjamin; Koo, John; Beroukhim, Kourosh | Abstract: BackgroundRecent studies into the pathogenesis of psoriasis have identified the importance of interleukin 17 (IL-17) in disease activity and have thus provided a new target for biologic therapy. Ixekizumab, the most recent US Food and Drug Administration (FDA)-approved anti-IL-17 biologic agent, appears to be a promising medication for patients suffering from moderate-to-severe plaque psoriasis.MethodsWe reviewed the results of phase III trials for ixekizumab in order to assess the efficacy, safety, and impact on quality of life of this agent in the treatment of plaque psoriasis. Additionally, we compared these results to phase II and phase III trials for other biologic psoriasis medications including the anti-IL-23 agents tildrakizumab and guselkumab, the combined anti-IL-12 and anti-IL-23 agent ustekinumab, and the anti-IL-17 agents brodalumab and secukinumab.ResultsPooled results from individual studies demonstrate that among the most efficacious dosing regimens of these anti-interleukin therapies, ixekizumab achieves higher Psoriasis Area and Severity Index 75 rates and similar or higher static Physician Global Assessment 0-1 rates than the other anti-IL-17 and anti-IL-23 agents. The safety profile of ixekizumab is similar to these agents, with nasopharyngitis, upper respiratory infection, headache, arthralgia, and injection-site erythema as the most commonly reported adverse events.ConclusionIxekizumab is a highly efficacious, newly FDA-approved treatment for moderate-to-severe plaque psoriasis that demonstrates a robust clinical response, significant improvement in patient quality of life, and a favorable safety profile.

Patients with psoriasis often enquire about the use of numerous botanical therapeutics. It is important for dermatologists to be aware of the current evidence regarding these agents. We conducted a systematic literature search using the PubMed, MEDLINE, and EMBASE databases for controlled and uncontrolled clinical trials that assessed the use of topical botanical therapeutics for psoriasis. The search included the following keywords: ‘psoriasis’ and ‘plant’ or ‘herbal’ or ‘botanical’. We also reviewed citations within articles to identify additional relevant sources. We then further refined the results by route of administration and the topical botanical agents are reviewed herein. A total of 27 controlled and uncontrolled clinical trials addressing the use of topical botanical agents for psoriasis were assessed in this review. We found that the most highly studied and most efficacious topical botanical therapeutics were Mahonia aquifolium, indigo naturalis, aloe vera, and, to a lesser degree, capsaicin. The most commonly reported adverse effects were local skin irritation, erythema, pruritus, burning, and pain. However, the overall evidence for these therapeutics remains limited in quantity and quality. The literature addresses a large number of studies in regard to botanicals for the treatment of psoriasis. While most agents appear to be safe, further research is necessary before topical botanical agents can be consistently recommended to patients.

The Department of Health and Human Services has announced a campaign for transitioning Medicare reimbursement from volume to value. A budget-neutral Value-Based Payment Modifier has been implemented that provides for differential payment to physicians based upon the quality of care delivered. The value modifier will be based partially on physician participation in the Physician Quality Reporting System (PQRS), which allows for reporting of information on quality of care to Medicare. The information reported includes both medical data and patient-reported experiences with health care providers. Starting in 2017, the value modifier payment adjustment will apply to all physicians who make Medicare part B fee-for-service charge claims. Physicians who do not participate in the PQRS and satisfy reporting requirements may be assessed negative adjustments to their payments. Dermatologists in particular will be impacted by these changes, as skin diseases, especially psoriasis, account for a significant economic burden in the U.S.

Author(s): Abrouk, Michael; Levin, Ethan; Brodsky, Merrick; Gandy, Jessica R; Nakamura, Mio; Zhu, Tian Hao; Farahnik, Benjamin; Koo, John; Bhutani, Tina | Abstract: Introduction:The 308 nm excimer laser is a widely used device throughout the field of dermatology for many diseases including psoriasis. Although the laser has demonstrated clinical efficacy, there is a lack of literature outlining the safety, efficacy, and patient acceptability of the excimer laser. Methods:A literature search on PubMed was used with combinations of the terms "excimer", "excimer laser", "308 nm", "psoriasis", "protocol", "safety", "efficacy", acceptability", "side effects", and "dose". The search results were included if they contained information pertaining to excimer laser and psoriasis treatment and description of the safety, efficacy, and patient acceptability of the treatment. Results:The 308 nm excimer laser is generally safe and well tolerated with minimal side effects including erythema, blistering, and pigmentary changes. It has a range of efficacies depending on the protocol used with several different treatment protocols, including the induration protocol, the minimal erythema dose protocol, and the newer minimal blistering dose protocol. Conclusion:Although the excimer laser is not a first-line treatment, it remains an excellent treatment option for psoriasis patients and has been demonstrated to be an effective treatment with little to no side effects.

Individuals with obsessive-compulsive features frequently visit dermatologists for complaints of the skin, hair or nails, and often progress towards a chronic relapsing course due to the challenge associated with accurate diagnosis and management of their psychiatric symptoms. The current DSM-5 formally recognizes body dysmorphic disorder, trichotillomania, neurotic excoriation and body focused repetitive behavior disorder as psychodermatological disorders belonging to the category of Obsessive-Compulsive and Related Disorders. However there is evidence that other relevant skin diseases such as delusions of parasitosis, dermatitis artefacta, contamination dermatitis, AIDS phobia, trichotemnomania and even lichen simplex chronicus possess prominent obsessive-compulsive characteristics that do not necessarily fit the full diagnostic criteria of the DSM-5. Therefore, to increase dermatologists' awareness of this unique group of skin disorders with OCD features, we propose a novel classification system called Obsessive-Compulsive Insight Continuum. Under this new classification system, obsessive-compulsive skin manifestations are categorized along a continuum based on degree of insight, from minimal insight with delusional obsessions to good insight with minimal obsessions. Understanding the level of insight is thus an important first step for clinicians who routinely interact with these patients.

Introduction: Quality of life (QoL) is an important issue in psoriatic disease that should be included when assessing therapeutic efficacy of treatments. The objective of this study was to compare improvement in the dermatology life quality index (DLQI) between patients treated with adalimumab and ustekinumab. Methods: Analysis was based on two separate open-label 24-week clinical trials assessing DLQI and the Psoriasis Area and Severity Index (PASI) at four-week intervals in adult subjects with moderate to severe psoriasis treated with adalimumab or ustekinumab. Results: There were no statistically significant differences in the improvement in DLQI and PASI between the adalimumab and ustekinumab groups except at week 12 for DLQI and week 8 for PASI (ustekinumab > adalimumab). Discussion: Both adalimumab and ustekinumab improve QoL, but further research is necessary to determine specific factors that improve QoL and if one medication improves QoL more than another.

Background The Goeckerman regimen remains one of the oldest, most reliable treatment options for patients with moderate to severe psoriasis. Goeckerman therapy currently consists of exposure to ultraviolet B light and application of crude coal tar. The details of the procedure can be confusing and challenging to understand for the first-time patient or provider. Objective To present a freely available online guide and video on Goeckerman treatment that explains the regimen in a patient-oriented manner. Methods The Goeckerman protocol used at the University of California—San Francisco Psoriasis and Skin Treatment Center as well as available information from the literature were reviewed to design a comprehensive guide for patients receiving Goeckerman treatment. Results We created a printable guide and video resource that covers the supplies needed for Goeckerman regimen, the treatment procedure, expected results, how to monitor for adverse events, and discharge planning. Conclusion This new resource is beneficial for prospective patients planning to undergo Goeckerman treatment, healthcare providers, and trainees who want to learn more about this procedure. Online media and video delivers material in a way that is flexible and often familiar to patients.

Erythrodermic psoriasis (EP) is a rare and severe variant of psoriasis vulgaris, with an estimated prevalence of 1%–2.25% among psoriatic patients. The condition presents with distinct histopathologic and clinical findings, which include a generalized inflammatory erythema involving at least 75% of the body surface area. The pathogenesis of EP is not well understood; however, several studies suggest that the disease is associated with a predominantly T helper 2 (Th2) phenotype. Given the morbidity and potential mortality associated with the condition, there is a need for a better understanding of its pathophysiology. The management of EP begins with a comprehensive assessment of the patient’s presentation and often requires multidisciplinary supportive measures. In 2010, the medical board of the US National Psoriasis Foundation published consensus guidelines advocating the use of cyclosporine or infliximab as first-line therapy in unstable cases, with acitretin and methotrexate reserved for more stable cases. Since the time of that publication, additional information regarding the efficacy of newer agents has emerged. We review the latest data with regard to the treatment of EP, which includes biologic therapies such as ustekinumab and ixekizumab., Video abstract

The Psoriasis Area and Severity Index (PASI) and Physician Global Assessment (PGA) are the most commonly used tools for the evaluation of psoriasis disease severity in clinical trials. Based on U.S. Food and Drug Administration requirements, many recent trials concerning measurement of psoriasis disease severity have included the PGA as a primary endpoint alongside the PASI. In this commentary, we review the advantages and disadvantages of the PASI and PGA scales, and discuss an example of a psoriasis patient in whom PGA fails to capture clinically significant disease improvement. We argue that despite its limitations, the PASI is a more accurate and descriptive instrument than the PGA for the assessment of psoriasis severity.

Introduction Interleukin-17 inhibitors are the newest class of monoclonal antibodies approved by the US Food and Drug Administration for the treatment of psoriasis. Preclinical and Phase II studies of ixekizumab, a high-affinity anti-IL-17A monoclonal antibody, have proved promising. Methods We conducted an extensive literature search using the PubMed database to assess the efficacy and safety profile of ixekizumab. The search included the following key words: “psoriasis” and “IL-17” or “ixekizumab.” We also reviewed citations within articles to identify relevant sources. Results By week 12, the percentage of patients achieving a 75% improvement from baseline Psoriasis Area and Severity Index (PASI 75) was comparable among the three Phase III trials (UNCOVER-1, 89%; UNCOVER-2, 90%; UNCOVER-3, 87%). Ixekizumab continued to be efficacious through 60 weeks of treatment. The safety profile of ixekizumab was favorable; the most frequently reported adverse events consisted of nasopharyngitis, upper respiratory tract infection, injection-site reaction, and headache. Conclusion Overall, ixekizumab demonstrated rapid clinical improvement and favorable short-term safety profile in Phase III trials. The results support ixekizumab as an effective therapeutic option for patients with moderate-to-severe plaque-type psoriasis.

Tumor necrosis factor-α inhibitors (TNFi) are the most widely used systemic treatments for patients with psoriasis and psoriatic arthritis. There currently exists a U.S. Food and Drug Administration issued warning label on all TNFi for "rare cases of new onset or exacerbation of central nervous system demyelinating disorders." The aim of this review was to update the incidence of TNFi-induced demyelinating diseases.Pubmed database was searched for safety data regarding demyelinating disease secondary to TNFi therapy prescribed for psoriasis.In clinical trials: 6990 patients had received treatment with etanercept with one reported case of multiple sclerosis; 5204 patients were treated with adalimumab with no cases identified and 2322 patients were treated with infliximab with one case of demyelinating polyneuropathy. Outside of clinical trials: 19 individual cases of demyelinating disorders from TNFi treatment have been reported.Although there is potential for TNF blockade to lead to demyelination of the central and peripheral nervous systems, the results of the present review suggest that demyelinating diseases associated with TNFi are extremely rare. TNFi are not recommended for use in patients with a personal history of demyelinating disease. However, with clinical vigilance and individualized treatment regimen, TNFi may be safe for use in other patients.

Background Allergic contact dermatitis (ACD) remains a significant burden of disease in the United States. Patch testing is the criterion standard for diagnosing ACD, but its use may be limited by reimbursement challenges. Objective This study aimed to assess the current rate of patch test utilization among dermatologists in academic, group, or private practice settings to understand different patch testing business models that address these reimbursement challenges. Methods All members of the American Contact Dermatitis Society received an online survey regarding their experiences with patch testing and reimbursement. Results A "yes" response was received from 28% of survey participants to the question, "Are you or have you been less inclined to administer patch tests or see patients needing patch tests due to challenges with receiving compensation for patch testing?" The most commonly reported barriers include inadequate insurance reimbursement and lack of departmental support. Conclusions Compensation challenges to patch testing limit patient access to appropriate diagnosis and management of ACD. This can be addressed through a variety of innovative business models, including raising patch testing caps, negotiating relative value unit compensation, using a fixed salary model with directorship support from the hospital, and raising the percentages of collection reimbursement for physicians.

Author(s): Farahnik, Benjamin; Patel, Viraat; Beroukhim, Kourosh; Zhu, Tian Hao; Abrouk, Michael; Nakamura, Mio; Singh, Rasnik; Lee, Kristina; Bhutani, Tina; Koo, John | Abstract: Background:The efficacy and safety of biologic and phototherapy in treating moderate-to-severe psoriasis is well known. However, some patients may not respond well to biologic agents or phototherapy on their own and may require combination therapy. Skillfully combining a biologic agent and phototherapy may provide an additive improvement without much increase in risks. Objective:To summarize the current state of evidence for the efficacy and safety of combining biologics with phototherapy in the treatment of moderate-to-severe plaque psoriasis. Methods:We conducted an extensive search on Pubmed database for English language literature that evaluated the use of a combination of biologic and phototherapy for the treatment of moderate-to-severe psoriasis through January 2016. The search included the following key-words: psoriasis, etanercept, adalimumab, infliximab, ustekinumab, biologics, phototherapy, and combination therapy. Results:The primary literature included randomized controlled trials, a head-to-head study, open-label controlled and uncontrolled trials, case series, and case reports. Etanercept was used in over half of the reported cases, but other biologic agents used included ustekinumab, adalimumab, and infliximab. The vast majority of phototherapy was narrowband ultraviolet B (NBUVB) radiation. Most cases reported enhanced improvement with combination therapy. Serious adverse events throughout the study duration were reported in l3% of the patients. Long-term adverse events cannot be excluded. Conclusion:Combination of biologic and phototherapy appears to be a viable clinical strategy in the treatment of moderate-to-severe psoriasis not responsive to monotherapy, despite limitations in the data available. NBUVB in combination with biologics appears to be especially effective. However, the long-term impact of these combinations is yet to be determined.

Background Psoriasis patients experience a significant decrease in quality of life (QoL). Objectives This study was conducted to prospectively measure changes in QoL of patients with moderate-to-severe psoriasis who are treated with ustekinumab. We performed a review of the literature, and discussed the significance of our results in the context of the controversy regarding the correlation between the Dermatology Life Quality Index (DLQI) and Psoriasis Area Severity Index (PASI). Methods Seventeen patients with moderate-to-severe plaque psoriasis received 36 weeks of ustekinumab and were followed every 4 weeks. Results All patients demonstrated significant improvement, both in terms of QoL and physical assessments. The data suggest a strong linear correlation between mean percent reduction in PASI and mean reduction in DLQI (R2=0.94). Conclusion Psoriasis patients treated with ustekinumab achieved significant improvement of QoL, which correlated with physical improvement. This study demonstrates a strong correlation between mean percent reduction in PASI and mean reduction in DLQI.

It is well known that psoriasis significantly impacts patients' quality of life (QoL). With the introduction of improved treatment modalities with biologic agents, more patients with moderate to severe psoriasis are able to achieve better results as measured by the Psoriasis Area and Severity Index (PASI). PASI 75 indicates a 75% or greater reduction in PASI scores from baseline and is indicative of excellent disease improvement. With newer biologic agents such as secukinumab, ixekizumab and brodalumab, patients are now capable of achieving PASI 90, introducing additional clinical decisions for physicians when considering treatment options. However, little is known regarding how the difference between achieving PASI-75 versus PASI-90 impacts patients' QoL.The purpose of this study was to compare how achieving PASI 75 versus PASI 90 impacts QoL for patients with moderate to severe plaque psoriasis by using validated psychometric instruments that have been widely used in both dermatologic and non-dermatologic settings.Two separate open-label clinical trials were conducted to specifically assess QoL in patients with moderate to severe psoriasis on adalimumab or ustekinumab over 24 weeks. In addition to clinical assessments of psoriasis, patients completed two surveys: The Psychological General Well-Being (PGWB) Index and the Dermatology Life Quality Index (DLQI). Changes in total PGWB score and DLQI score at weeks 12 and 24 compared to baseline were compared between groups achieving PASI 75 and PASI 90.There was no statistically significant difference in PGWB scores between patients achieving PASI 75 and patients achieving PASI 90 in the adalimumab treatment group (week 12 p = .21, but there was at week 24 p = .05). There was a statistically significant difference in DLQI between the patients achieving PASI 75 and the patients achieving PASI 90 in the adalimumab treatment group at week 24 (p = .01), but not week 12 (p = .11). There was no statistically significant difference in PGWB scores between patients achieving PASI 75 and patients achieving PASI 90 in the ustekinumab treatment group (week 12 p = .11, week 24 p = .35). There was no statistically significant difference in DLQI between the patients achieving PASI 75 and the patients achieving PASI 90 in the ustekinumab treatment group at week 24 (week 12 p = .49, week 24 p = .11).There has been tremendous attention surrounding newer biologic agents that can achieve PASI 90 and even PASI 100. Although the results are impressive with regard to physical improvement of psoriasis, there may not be a clinically significant difference in QoL when comparing patients who achieve PASI-75 versus PASI 90.

Atopic dermatitis (AD) is a common inflammatory dermatosis characterized by pruritus, erythema, induration, and lichenification. Current treatment options for generalized atopic dermatitis are limited and have potentially serious adverse effects, especially in patients with severe, chronic AD who frequently require systemic anti-inflammatory agents. Apremilast, an oral phosphodiesterase-4 inhibitor, was FDA approved in September 2014 for the treatment of moderate-to-severe plaque psoriasis. However, its upstream anti-inflammatory effects, ease of use as an oral agent, and mild side-effect profile make it an interesting treatment option for AD as well. Herein, we present a patient with a life-long history of AD recalcitrant to topical steroids and cyclosporine who attained subjective and objective improvement in pruritus and erythema after 10-week treatment with apremilast.

Background: Striae gravidarum (SG) are atrophic linear scars that represent one of the most common connective tissue changes during pregnancy. SG can cause emotional and psychological distress for many women. Research on risk factors, prevention, and management of SG has been often inconclusive. Methods: We conducted a literature search using textbooks, PubMed, and Medline databases to assess research performed on the risk factors, prevention, and management of SG. The search included the following key words: striae gravidarum, pregnancy stretch marks, and pregnancy stretch. We also reviewed citations within articles to identify relevant sources. Results: Younger age, maternal and family history of SG, increased pre-pregnancy and pre-delivery weight, and increased birth weight were the most significant risk factors identified for SG. Although few studies have confirmed effective prevention methods, Centella asiatica extract, hyaluronic acid, and daily massages showed some promise. Treatment for general striae has greatly improved over the last few years. Topical tretinoin ≥0.05% has demonstrated up to 47% improvement of SG and non-ablative fractional lasers have consistently demonstrated 50 to 75% improvement in treated lesions of striae distensae. Conclusion: Overall, SG has seen a resurgence in research over the last few years with promising data being released. Results of recent studies provide dermatologists with new options for the many women who are affected by these disfiguring marks of pregnancy. Keywords: Striae gravidarum, pregnancy, stretch marks, striae distensae

There have been rare reports of eczema occurring as an adverse effect of anti-tumor necrosis factor-alpha (TNFα) therapy.A literature search was conducted on PubMed for articles describing new onset or worsening of preexisting eczema during anti-TNFα therapy for the treatment of various inflammatory diseases.Eczema as an adverse effect of anti-TNFα therapy may occur in approximately 5-20% of patients with various Th1-mediated inflammatory diseases such as psoriasis, inflammatory arthritis and inflammatory bowel disease. Personal history of atopy appears to increase this risk. Out of the anti-TNFα agents indicated for the treatment of moderate-to-severe psoriasis, infliximab may be more strongly associated with development or exacerbation of preexisting eczema.Inhibitors of key mediators in the Th1 pathway such as TNFα are successful therapeutic targets for the treatment of various inflammatory conditions such as psoriasis, psoriatic arthritis, rheumatoid arthritis and inflammatory bowel disease. Blocking the Th1 pathway may create an imbalance favoring increased activity of the opposing Th2 pathway implicated in inflammatory conditions such as eczema. Further research is needed to better understand the role of the Th1/Th2 balance in various inflammatory diseases and how the immunologic environment is affected by immunotherapies.

Hailey–Hailey disease or familial benign chronic pemphigus is a rare blistering dermatosis that is characterized by recurrent erythematous plaques with a predilection for the skin folds. For extensive Hailey–Hailey disease that is recalcitrant to conventional therapy, laser ablation, photodynamic therapy, electron beam radiotherapy, botulinum toxin type A, dermabrasion, glycopyrrolate, and afamelanotide have been reported as useful treatments, but comparative trials are lacking. This review discusses the various treatment modalities for Hailey–Hailey disease and a summary of the evidence for the most recommended treatments.

The negative impact of psoriasis on quality of life is well documented. Psoriasis is also associated with impairments in work productivity and daily activities.This study was conducted to prospectively measure the impact of ustekinumab treatment on work productivity and daily activity impairments due to psoriasis, using the Work Productivity and Activity Index: Psoriasis instrument.Thirty-two patients with moderate-to-severe plaque psoriasis received 36 weeks of ustekinumab and were followed every 4 weeks. During each visit, patients were evaluated using the Psoriasis Area Severity Index and Work Productivity and Activity Index: Psoriasis instrument.Thirty-two patients completed the study. There was no change in unemployment rate after treatment. Twenty-two patients who were employed at both baseline and week 36 experienced a significant decrease in total work productivity impairment, presenteeism and a non-significant decrease in absenteeism. All patients demonstrated significant reduction in total activity impairment.This study was limited by the lack of a placebo group and a small sample size.This study demonstrates the benefits of ustekinumab treatment in terms of reducing psoriasis-related work productivity and activity impairments among patients with moderate-to-severe psoriasis.

As most efforts in the last decade have focused on the immunologic basis of inflammatory skin disease, there has been less emphasis on the role of the nervous system in the disease process of psoriasis. Evidence in support of the neurocutaneous pathway has come from observations of patients experiencing unilateral improvement and even complete remission following nerve damage in the affected dermatomal region. The aim of this review was to investigate the role of neuropeptides in the intricate pathophysiology of psoriasis. The PubMed database was searched for individual case reports or case series that reported clearance or significant improvement in psoriatic disease in patients following documented nerve injury. A total of 11 cases were found that reported improvement of psoriatic lesions in areas afflicted by central or peripheral nerve injury. The most common causes of denervation were inadvertent surgical interruption, cerebrovascular accident, and poliomyelitis. In four cases the patients eventually regained neurologic function, which was associated with a recurrence of skin lesions. In cases of permanent nerve damage, there was remission of psoriasis. The cases reported in the literature to date provide clinical evidence that absence of neural input leads to psoriasis improvement, suggesting a crucial role of the nervous system in the pathophysiology of psoriatic disease. In fact, neuropeptides such as nerve growth factor, substance P, calcitonin gene-related peptide, and vasoactive intestinal peptide may be important contributors of psoriatic disease and potential targets for future therapies.

On June 30th 2015, the FDA instituted a new system for the categorization of drug safety during pregnancy and lactation, known as the Pregnancy and Lactation Labeling Rule (PLLR), which replaces the "A, B, C, D, X" pregnancy labeling categories. The new rule will apply to all newly approved prescription medications, with a staggered phase-in for prescription drugs approved prior to the effective date. In this article, we provide a brief description of the major changes introduced by the PLLR and discuss the major implication of this new categorization system for clinical dermatologists.

Phototherapy involves repeated exposure of the skin to ultraviolet light to treat various inflammatory skin conditions such as psoriasis. Recent studies have identified specific immunologic effects of phototherapy that may underlie phototherapy efficacy. Furthermore, recent advancements have been made in developing safe and effective targeted phototherapy modalities for difficult-to-treat areas such as scalp psoriasis. Targeted phototherapy in the form of the excimer laser holds potential for more aggressive, effective treatment and long-lasting remission of psoriasis. Phototherapy is now also used successfully with biologic agents as combination therapy to treat recalcitrant psoriasis. Therefore, though one of the oldest therapeutic modalities for psoriasis, phototherapy remains a mainstay treatment with promise for further advancement.

Background PUVA treatment is photochemotherapy for psoriasis that combines psoralen with UVA radiation. Although PUVA is a very effective treatment option for psoriasis, there is an absence of patient resources explaining and demonstrating the process of PUVA. Studies have shown that patients who viewed videos explaining the treatment procedures for various medical conditions had a greater understanding of their treatment and were more active participants in their health. Objective To present a freely available online guide and video on PUVA treatment designed for patient education on PUVA. Methods The PUVA treatment protocol used at the University of California—San Francisco Psoriasis and Skin Treatment Center as well as available information from the literature was reviewed to design a comprehensive guide for patients receiving PUVA treatment. Results We created a printable guide and video resource that reviews the benefits and risks of PUVA, discusses the three types of PUVA (hand–foot soak, full body soak, and systemic), demonstrates the PUVA process, and provides practical tips for safe use. Conclusion Online media and video delivers material in a way that is flexible and often familiar to patients. This new format is beneficial for prospective patients planning to undergo PUVA treatment, health-care providers, and trainees who want to learn more about this treatment.

Background An increasing number of injectable biologics are now available for the treatment of psoriasis. However, for individuals who have never received this therapy, the process of performing a self-injection can be daunting. There is lack of patient educational material on how to perform and optimize this treatment. Objective The objective of this study is to present a freely available online guide and video on biologic injections that is informative to patients and increases the success and compliance of patients starting this therapy. Methods The self-injection technique taught at the University of California—San Francisco Psoriasis and Skin Treatment Center as well as available information from the literature were reviewed to design a practical guide for patients receiving biologic injections. Results We created a printable guide and video resource that describes how to improve the injection process, pain management, travel planning, and common concerns with biologic injectables. Conclusion This guide is beneficial for patients who wish to improve their experience with biologic self-injections, for healthcare providers who prescribe these treatments, and for trainees learning about this modality.

Introduction Interleukin (IL)-17 inhibitors are the most recent class of monoclonal antibodies approved by the FDA for psoriasis treatment. Preclinical and phase II studies of brodalumab, a high-affinity IL-17 receptor monoclonal antibody, have been encouraging. Methods We conducted a literature search using the PubMed database in order to assess the efficacy and safety profile of brodalumab. The search included the following key words: “psoriasis” and “IL-17” or “brodalumab.” We also reviewed citations within articles to identify relevant sources. Results At week 12, the proportion of patients attaining a 75% improvement from the baseline Psoriasis Area and Severity Index (PASI 75) was similar among the three phase III trials (AMAGINE-1, 83%; AMAGINE-2, 86%; AMAGINE-3, 85%). Brodalumab remained efficacious through 52 weeks of treatment. It maintained a satisfactory safety profile; the most frequently reported adverse events consisted of nasopharyngitis, headache, upper respiratory tract infection, and arthralgia. Conclusion Use of brodalumab revealed prompt clinical improvement and a favorable short-term safety profile in phase III trials, although further extension studies are needed to assess long-term safety. Based on the results, brodalumab appears to be a potent therapeutic option for patients with moderate-to-severe plaque-type psoriasis.
