Erythema Ab Igne and Malignant Transformation to Squamous Cell Carcinoma.

Erythema ab igne (EAI) is a cutaneous reaction resulting from prolonged exposure to an infrared heat source at temperatures insufficient to cause a burn. It is most commonly reported on the lower extremities and back, and it presents with persistent areas of reticular erythema associated with hyperpigmentation, epidermal atrophy, and telangiectases. Erythema ab igne traditionally is associated with chronic exposure to open fires and coal stoves.

Spectrum of orocutaneous disease associations: Genodermatoses and inflammatory conditions.

The oral cavity and cutaneous organ systems share a close embryologic origin. Therefore, there are numerous dermatologic conditions presenting with concomitant oral findings of which the dermatologist must be aware. The second article in this continuing medical education series reviews inflammatory orocutaneous conditions and a number of genodermatoses.

Spectrum of orocutaneous disease associations: Immune-mediated conditions.

There are a number of diseases that manifest both on the skin and the oral mucosa, and therefore the importance for dermatologists in clinical practice to be aware of these associations is paramount. In the following continuing medical education series, we outline orocutaneous disease associations with both immunologic and inflammatory etiologies.

Ustekinumab treatment for psoriasis in 119 patients maintained on therapy for a minimum of one year: a review.

Ustekinumab is a human IgG1κ monoclonal antibody that binds with high affinity and specificity to the p40 protein subunit shared by both the interleukin-12 and interleukin-23 cytokines. This study reviews clinical response and adverse events in 119 psoriasis patients who have received ustekinumab for a minimum of 1 year. The medical records of 119 psoriasis patients treated with ustekinumab at our referral clinic in Dallas between 2009 and 2013 were reviewed for response rates, side effects, and concomitant therapies.
