Seborrheic dermatitis is a common papulosquamous disorder of the skin, affecting 3% to 5% of the population. Dandruff, a less severe form of seborrheic dermatitis, affects a greater proportion of the population. The exact pathogenesis of seborrheic dermatitis is unknown, however colonization of the lipophilic yeast, Malasezzia furfur, and an inflammatory reaction to this yeast each seem to play a role in disease etiology. Therefore, treatment for seborrheic dermatitis is aimed at yeast elimination and inflammation control. Several treatment modalities are available for seborrheic dermatitis and dandruff including shampoos, which contain both active ingredients related to antimycotic or anti-inflammatory effects and also surfactant ingredients that allow these shampoos to replace regular shampoos in affected patients. The literature regarding the treatment of therapeutic shampoos is reviewed, and treatment strategies for managing seborrheic dermatitis with therapeutic shampoos are provided.

The classic “nature–nurture” debate continues to stimulate research in human behavior. This chapter explores how experience (nurture) can modulate brain architecture and brain function. These cases illustrate how childhood experiences can have lifelong effects on behavior and well-being. At the end of this chapter, the reader will be able to 1. Discuss the role of early experience on normal brain development 2. Identify early adverse effects of deprivation 3. Determine some common deficits which result from early deprivation 4. Describe resilience and differences in innate ability
