Rosacea: update on management and emerging therapies.

Rosacea is a common chronic skin disorder that has significant impact on the self-esteem and quality of life of affected individuals. Currently understood as an inflammatory condition that occurs in the context of an altered innate immune response, the available topical and systemic therapies function as immunomodulators to restore cutaneous homeostasis. The goals of therapy include reduction of papules, pustules, erythema and physical discomfort with improvement in quality of life.

Impact of the number of dermatologists on dermatology biomedical research: a Canadian study.

Background: Fewer dermatologists than other clinical specialists are entering and being retained as physicians in the Canadian medical workforce. Studies suggest that dermatologist numbers may influence skin disease outcomes. No study has questioned whether the number of clinical dermatologists can influence academic productivity.

Immunotherapies in dermatologic disorders.

Treatment modalities and therapeutic response experience support the use of immunotherapy in the treatment of many diseases in all fields of medicine. The aim of this article is to conduct and present a review of literature on the use of immunotherapy in the treatment of skin diseases analyzing scientific literature available up to January 2012. Studies that presented evidence-based data were selected.

Cytokine-based therapy in psoriasis.

Psoriasis and psoriatic arthritis are chronic inflammatory diseases of unknown etiology, affecting 2-3% of the world population. Initially, psoriasis was thought to be a hyper-proliferation disorder of keratinocytes only, but as time passed, the role of immune system became more evident and now both diseases are considered autoimmune disorders. In last few years, the discovery of interleukin (IL)-23/Th17 axis in pathophysiology of psoriatic diseases shifts the cytokine paradigm from Th1 to Th17 cytokines, focused mainly on IL-17 and IL-22.

Ingenol mebutate: an introduction.

The incidence of nonmelanoma skin cancer continues to increase. While surgical excision remains the mainstay of treatment, growing demand from patients for effective, tissue-sparing approaches with good cosmetic results has led to the development of novel therapeutic agents. Several studies have reported on the safety and efficacy of topical ingenol mebutate gel, a derivative of the plant Euphorbia peplus, in the treatment of actinic keratosis and superficial basal cell carcinoma.

Bedbugs: an update on recognition and management.

The common bedbug (Cimex lectularius) is increasingly prevalent and a source of concern and questions for patients. In addition to a range of cutaneous presentations and potential for serious sequelae, bedbug bites cause significant psychological distress and create an economic burden associated with infestation control. Recognition of characteristic entomology, clinical presentation, diagnostic features and differential diagnosis can support expedient identification of patients exposed to infestations and support their appropriate management.
