Treating to Target(s) With Interleukin-17 Inhibitors.

BACKGROUND:: The treat-to-target (T2T) strategy has become established in several medical specialties as a key guidance to optimal therapeutic decision making. T2T may be effective in the assessment of the biologic class of agents called interleukin (IL)-17 inhibitors, which are emerging as a safe and effective treatment option for autoimmune inflammatory conditions such as plaque psoriasis, psoriatic arthritis (PsA), and ankylosing spondylitis (AS). OBJECTIVE:: The objective of this article is to use a T2T approach for the evaluation of the effectiveness and safety of IL-17 inhibitors in the management of patients with plaque psoriasis, PsA, and AS. METHODS:: Following a comprehensive literature search, a full-day meeting was convened to discuss and identify the T2T targets for psoriasis, PsA, and AS. Clinical trial evidence was presented for the approved IL-17 inhibitors-secukinumab, ixekizumab, and brodalumab-to assess whether these data meet T2T safety and efficacy targets. RESULTS:: All 3 approved agents were significantly superior to placebo and active controls in the achievement of T2T targets for psoriasis. Secukinumab and ixekizumab were likewise associated with significantly better outcomes than controls in the PsA targets, and secukinumab resulted in significant AS target improvements vs placebo. The IL-17 inhibitors were also associated with low rates of serious adverse events and exacerbations of common comorbid conditions. CONCLUSION:: Phase III trial results support the T2T benefit and safety of IL-17 inhibitors according to their specific indications for the management of patients with plaque psoriasis, PsA, and AS.

Using Visual Aids to Enhance Physician-Patient Discussions and Increase Health Literacy.

Health literacy refers to the comprehension required to make well-informed decisions regarding one's health. It is a critical component in helping patients to understand how to take their medications appropriately. However, many patients do not possess the comprehension necessary for medication adherence. The result of poor literacy is a higher incidence of misunderstanding medication instructions. Visual aids have the ability to transcend language and numeracy barriers and can therefore improve the effectiveness of communication and broaden target audiences. To enhance communication that is language independent, a template was created to provide instructions for proper use and explanation of risks for adverse events. This template is designed to fit on a single double-sided page. This template can be adapted for use in explaining any medication using universal pictograms available from online resources. This would enable any practitioner to design information sheets for their unique use.

Non-melanoma Skin Cancer in Canada Chapter 1: Introduction to the Guidelines.

BACKGROUND: Non-melanoma skin cancer (NMSC), including basal and squamous cell carcinoma, represents the most common malignancy. OBJECTIVE: The aim of this document is to provide guidance to Canadian health care practitioners on NMSC management. METHODS: After conducting a literature review, the group developed recommendations for prevention, management, and treatment of basal cell carcinomas, squamous cell carcinomas, and actinic keratoses. These tumour types are considered separately in the accompanying articles. The Grading of Recommendations Assessment, Development and Evaluation system was used to assign strength to each recommendation. RESULTS: This introduction describes the scope and structure of the guidelines and the methods used to develop them. The epidemiology of NMSC is reviewed, as are the pathophysiologic changes occurring with damage to the skin, which lead to the formation of actinic keratoses and invasive squamous or basal cell carcinomas. CONCLUSIONS: This introduction describes the need for primary prevention and offers an overview of treatment options that are discussed in later chapters of the guidelines.

Non-melanoma Skin Cancer in Canada Chapter 2: Primary Prevention of Non-melanoma Skin Cancer.

BACKGROUND: Non-melanoma skin cancer (NMSC), including basal and squamous cell carcinoma (BCC and SCC), represents the most common malignancy. OBJECTIVE: To provide guidance to Canadian health care practitioners regarding primary prevention of NMSC. METHODS: Structured literature searches were conducted, using search terms including prevention, sunscreen, and sun prevention factor. All recommendations concern guidance that physicians should regularly discuss with their patients to help establish photoprotection habits. The GRADE system was used to assign strength to each recommendation. RESULTS: Ultraviolet exposure is the major modifiable risk factor for NMSC. Aspects of photoprotection, including effective sunscreen use and avoidance of both the midday sun and artificial tanning, are discussed. Several widespread misunderstandings that undermine responsible public health measures related to sun safety are addressed. CONCLUSIONS: Photoprotection represents both an individual priority and a public health imperative. By providing accurate information during routine patient visits, physicians reinforce the need for ongoing skin cancer prevention.

The amazing vanishing Canadian dermatologist: results from the 2006 Canadian Dermatology Association member survey.

BACKGROUND: The 2006 Canadian Dermatology Association (CDA) member survey tracked the Canadian dermatology workforce. Information on use of nondermatologist extenders, impact of financial burden on practice style, and wait times was collected in the survey. OBJECTIVE: To survey Canadian dermatologists for specialty-specific physician resource information including demographics, workload, and future career plans and compare it to results from the 2001 survey. In addition, to explore three other areas not covered in the previous survey: patient access to dermatologic care through wait times, the use of nondermatologist extenders, and potential impact of educational financial debt on practice styles. METHODS: CDA members in 2006 were surveyed by mail. Follow-up mailings were done for nonresponders. Survey results were compared to those of the 2001 survey. RESULTS: Thirty-six percent (216 of 602) of Canadian dermatologists responded (70% in 2001). The national distribution was identical between surveys. The median age increased to 55 years; two-thirds of dermatologists are male. The median retirement age remained at 65 years. There was a shift from rural to urban practice locations; 78% practice in private offices. Three-fifths of dermatologists do mainly medical dermatology, a decrease between surveys. Pediatric dermatology decreased 10%, whereas surgical dermatology increased 52% between surveys. Fewer practitioners perform noninsured services, and half as many perform research or hospital consultations or teach medical students. Financial debt burden had no impact on selection of practice style. Median wait times for nonurgent consultations doubled from 5 to 10 weeks; follow-up visits increased from 4 to 5 weeks; noninsured consultations increased from 4 to 5 weeks. The national median wait time for a third available consultation appointment was 42 days (range 7-161 days). Seventeen percent of dermatologists reported using nondermatologist extenders. Training programs produce only 60% of new practitioners needed to replace retirees over the next 5 years. Existing training programs are at full capacity, and only the creation of new programs can expand training capacity. CONCLUSIONS: Although the face of Canadian dermatology shows a productive specialty committed to patient care, teaching, and research, the demographics of the Canadian baby boom generation will have a major negative impact on the effectiveness of Canadian dermatology in the service of the Canadian population. The attrition rate predicted in the 2001 survey and validated by the 2006 survey spotlights the critical imperative for the specialty to adapt to the future of a shrinking workforce in the face of expanding demand for its services.

Hidradenitis suppurativa in 64 female patients: retrospective study comparing oral antibiotics and antiandrogen therapy.

BACKGROUND: Hidradenitis suppurativa (HS) is a recurrent disease confined to apocrine gland-bearing areas causing painful, deep-seated lesions and draining sinus tracts. Uniformly effective therapy is lacking. Improvements in current medical management strategies are needed. OBJECTIVE: We sought to determine the success rate for a variety of treatments in our female HS patients and whether androgen-related tests can predict a response to antiandrogen therapy. As HS has been linked to a hyperandrogen state, we sought to determine if it is also associated with polycystic ovary syndrome (PCOS). METHODS: A retrospective chart review was performed examining hormonal profiles and the response to a variety of treatments in female patients with HS. RESULTS: Sixty-four female HS patients were identified (mean age 33 years). Antiandrogen therapy was superior to oral antibiotic therapy (55% vs 26%) based on a two-sample, two-sided, t-test statistic (p < .04). The prevalence of PCOS among our study patients in whom androgen markers were available was 8 of 21 (38.1%), and even if taken over all study patients, not necessarily investigated for PCOS, the prevalence was 8 of 64 (12.5%). This reflects a greater than expected prevalence among all women (10%). CONCLUSION: As a proof-of-concept study, despite limitations inherent in a retrospective chart review, there is sufficient signal to suggest that a hormonal manipulation approach to therapy should be considered in all women presenting with HS. Female patients presenting with HS should prompt investigations for underlying PCOS and insulin resistance.

The Canadian Dermatology Workforce Survey: implications for the future of Canadian dermatology--who will be your skin expert?

OBJECTIVE: To survey Canadian dermatologists for specialty-specific physician resource information including demographics, workload and future career plans. BACKGROUND AND METHODS: In 2001, the Canadian Dermatology Association (CDA) surveyed 555 dermatologists in Canada to gain specialty-specific physician resource information. Three hundred and seventy-one dermatologists (69%) provided information about themselves, their workloads and their future career goals. RESULTS: The average Canadian dermatologist is 52 years old and 35% of practicing dermatologists are over the age of 55. Eighty-nine percent of dermatologists practice in an urban setting, 19% include practice in a rural setting while less than 0.5% practice in remote areas. Canadian dermatologists spend 61% of their clinical time providing services in Medical Dermatology. Within 5 years, 50% of dermatologists reported that they plan to reduce their practices or retire. CONCLUSION: The Canadian Dermatology Workforce Survey provides a snapshot of the current practice of dermatology in Canada. It also serves to highlight the critical shortage of dermatologists, which will continue to worsen without immediate, innovative planning for the future.
