    Neumomediastino y necrosis cutánea en asociación a dermatomiositis: presentación de un caso clínico y revisión de la literatura
    (Sociedad Médica de Santiago, 2015) Gallardo, Natalia; Valenzuela, Omar; Ibáñez, Sebastián
    We report a 37 years old male with a dermatomyositis treated with oral cyclophosphamide. He was admitted to the hospital due to a zone of skin necrosis with purulent exudate, located in the second left toe. A complete blood count showed a leukocyte count of 2,600 cells/mm3. A Chest CAT scan showed a pneumomediastinum with emphysema of adjacent soft tissue. Cyclophosphamide was discontinued and leukocyte count improved. The affected toe was amputated and a chest CAT scan showed a partial resolution of the pneumomediastinum. We discuss and review the pathogenesis, clinical presentation and management of pneumomediastinum and cutaneous necrosis in association with dermatomyositis.

    Switching stable kidney transplant recipients to a generic tacrolimus Is feasible and safe, but it must be monitored
    (Hindawi Publishing Corp., 2017) González, Fernando; López, René; Arriagada, Elizabeth; Carrasco, René; Gallardo, Natalia; Lorca, Eduardo
    Background. Tacrolimus is the primary immunosuppressive drug used in kidney transplant patients. Replacing brand name products with generics is a controversial issue that we studied after a Chilean Ministry of Health mandate to implement such a switch. Methods. Forty-one stable Prograf (Astellas) receiving kidney transplant patients were switched to a generic tacrolimus (Sandoz) in a 1 : 1 dose ratio and were followed up for up to 8 months. All other drugs were maintained as per normal practice. Results. Neither tacrolimus doses nor their trough blood levels changed significantly after the switch, but serum creatinine did: 1.62 ± 0.90 versus 1.75 ± 0.92 mg/dL (p < 0.001). At the same time, five graft biopsies were performed, and two of them showed cellular acute rejection. There were nine infectious episodes treated satisfactorily with proper therapies. No patient or graft was lost during the follow-up time period. Conclusion. Switching from brand name tacrolimus to a generic tacrolimus (Sandoz) is feasible and appears to be safe, but it must be monitored carefully by treating physicians.
