The significant progress made in psoriatic disease research since the launch of the National Psoriasis Foundation in 1967 has expanded our knowledge base and led to the development of life-changing treatment options, including:
- Topicals
- Phototherapy
- Biologics
- Oral Treatments
Even with all the information available today, providers may still have questions. For example:
- Are patients with chronic plaque psoriasis candidates for UVB phototherapy?
- Are all systemic treatments also biologics?
- What are the side effects of adalimumab?
Answers to these questions and more are easily accessible in The Psoriasis and Psoriatic Arthritis Pocket Guide: Treatment Algorithms and Management Options.
After studying this handbook, physicians should be able to:
- Define the severity of psoriasis and develop an appropriate therapy plan.
- Explain the profound emotional, social, and physical impact psoriatic disease has on the patient.
- Understand the important comorbidities associated with psoriasis.
- Differentiate psoriasis from other diseases after evaluating patients who present with similar types of skin lesions.
- Diagnose patients who have moderate disease (3% to 10% body involvement) and severe disease (>10% body involvement).
