    Linear IgA bullous dermatosis: report of five cases in Chile
    (WILEY, 2012) Sandoval, Mauricio; Magdalena Farias, Maria; Gonzalez, Sergio
    Background Linear IgA bullous dermatosis (LABD) is an acquired autoimmune sub-epidermal vesiculobullous disease characterized by continuous linear IgA deposit on the basement membrane zone, as visualized on direct immunofluorescence microscopy. LABD can affect both adults and children. The disease is very uncommon, with a still unknown incidence in the South American population. Materials and methods All confirmed cases of LABD by histological and immunofluorescence in our hospital were studied. Results The confirmed cases were three females and two males, aged from 8 to 87 years. Precipitant events associated with LABD were drug consumption (non-steroid inflammatory agents in two cases) and ulcerative colitis (one case). Most of our patients were treated with dapsone, resulting in remission. Discussion Our series confirms the heterogeneous clinical features of this uncommon disease in concordance with a larger series of patients reported in the literature.

    Periorbital Syringoma Treated With Radiofrequency and Carbon Dioxide (CO2) Laser in 5 Patients
    (JOURNAL OF DRUGS IN DERMATOLOGY, 2012) Hasson, Ariel; Magdalena Farias, Maria; Nicklas, Claudia; Navarrete, Cristian
    Syringomas are common benign eccrine ductal adnexial tumors, commonly found in periorbital area. Periorbital syringomas are aesthetically disturbing difficult to treat. Many treatment modalities are described in the literature, including topical and surgical methods, with potential problems such as postinflammatory hyper- and hypopigmentation, low efficacy, or scar formation. We present 5 patients with syringoma treated with the combination of radiofrequency ablation and carbon dioxide (CO2) lasers. Using low-energy parameters on the CO2 laser, and low energy on the radiofrequency, we could complement both treatments maximizing the destruction of the tumors and minimizing the adverse effects in only two sessions. This is a relatively easy, safe, and less painful treatment, with good cosmetic results on periorbital syringomas.
