An Open-Label Pilot Study to Evaluate the Efficacy of Tofacitinib in Moderate to Severe Patch-Type Alopecia Areata, Totalis, and Universalis.

Alopecia areata (AA) is a common autoimmune disease with a lifetime risk of ∼2%. In AA, the immune system targets the hair follicle, resulting in clinical hair loss. The prognosis of AA is unpredictable, and currently there is no definitive treatment.

Methotrexate-Induced Nasal Septal Perforation.

A 58-year-old woman with a 31-year history of Hailey-Hailey (HH) disease that was refractory to treatment with mycophenolate mofetil, cyclosporine, dapsone, sulfasalazine, topical/oral antibiotics, and topical/oral steroids presented for alternative treatment options. Active erythematous, malodorous, eroded, and crusted plaques were present in the axillae, inframammary region, groin, and back (Figure 1). The patient had an undulant course, with acute exacerbations and partial remissions.

Autoimmune bullous diseases in childhood.

Autoimmune blistering disorders are a heterogeneous group of diseases that result from autoantibodies generated against target antigens found in the skin and mucous membranes. This process leads to a variety of disruptions in keratinocyte adhesion and cellular integrity, resulting in fluid accumulation and development of blisters. Physicians should have an appreciation and understanding of autoimmune blistering disorders in the pediatric population when formulating a differential diagnosis of a patient who presents with skin blistering.
