Rituximab: Uses in Dermatology.

Rituximab is an anti-CD20 monoclonal antibody with considerable potential in dermatology due to an increase in off-label indications. Chronic graft-versus-host disease and pemphigus vulgaris are two of the most promising indications for off-label use of rituximab. It is a generally safe alternative that should be considered when traditional therapy with corticosteroids or immunosuppressants has failed or caused significant intolerance. Currently, rituximab is only FDA-approved for treatment of follicular and diffuse large B-cell non-Hodgkin's lymphoma, rheumatoid arthritis, chronic lymphocytic leukemia, granulomatosis with polyangiitis (formerly Wegener's granulomatosis) and microscopic polyangiitis. Herein, off-label uses of rituximab and its efficacy in the treatment of cutaneous diseases are reviewed.

New antibiotics in the management of acute bacterial skin and skin structure infections.

Acute bacterial skin and skin-structure infections (ABSSSIs), often caused by aerobic gram-positive cocci, are most often mild-tomoderate infections that can easily be treated in an outpatient setting. With the rates of these infections substantially increasing in the past decade, owing in part to the emergence of community acquired methicillin-resistant Staphylococcus aureus (CA-MRSA), alternative options for the treatment of ABSSSIs are necessary. This editorial reviews the mechanism of action, efficacy, bacterial coverage, and potential side effect profiles for dalbavancin and oritavancin, both semisynthetic lipoglycopeptide antibiotics, and tedizolid, an oxazolidinone. Dalbavancin, oritavancin, and tedizolid have been extremely valuable additions to treatment options for ABSSSIs due to the convenient dosing regimen and the fact that there are fewer resistant organisms to these therapies at this time.
