Facial Discoid Dermatosis. A 13-Case Series.

Facial discoid dermatosis (FDD) is a condition characterized by papules-plaques primarily affecting the face. FDD has been associated with psoriasis, seborrheic dermatitis, and pityriasis rubra pilaris. We conducted a retrospective multicenter study with 13 patients diagnosed with FDD in Spain (2014-2022).

A Randomized Clinical Trial to Evaluate the Efficacy of an Oral Probiotic in Acne Vulgaris.

The relevance of the gut microbiota in some skin inflammatory diseases, including acne vulgaris, has been emphasized. Probiotics could play a role in the modulation of the microbiota, improving the clinical course of this disease. A 12-week randomized, double-blind, placebo-controlled, clinical trial with patients aged 12 to 30 years with acne vulgaris was conducted.

Solar urticaria unresponsive to intravenous immunoglobulins.

The treatment of solar urticaria (SU) can be difficult. Only a few cases of SU have been treated with intravenous immunoglobulins (IVIg) (as monotherapy or combined with phototherapy), with reported fast and durable increase of solar exposure tolerance. A 61-year-old female with severe UVB- and UVA-induced SU and a 62-year-old female with severe UVA and visible light-induced SU were both treated with a single course of IVIg (total dose of 2 g/kg), infused over 3 days.

Calcinosis cutis and Sjögren's syndrome.

Cutaneous calcinosis can be classified into four types: dystrophic, metastatic, idiopathic and iatrogenic. Dystrophic calcification constitutes the most frequent variant and is associated with a large number of illnesses, among which are included some collagen diseases such as CREST syndrome, scleroderma, dermatomyositis and lupus erythematosus. We present a case of dystrophic calcinosis cutis, affecting the fingertip of a woman with a 10-year history of primary Sjögren's syndrome (SS).
