Fully Digital Workflow for Fabrication of A 3D Printed Ear Stent for Auricular Keloids: A Technique Article.

Keloids are skin lesions which result from an aberration in the physiological healing process marked with overgrowth of collagen fibers. Keloid of the ear is cosmetically challenging and has an increased chance of re-growth. To minimize recurrence, pressure therapy in combination with other treatment forms has been used. Various techniques have been used to fabricate a passive or active stent. This report presents a fully digital workflow to fabricate an ear stent after intralesional excision and skin autografting of an extensive recurrence of a keloid lesion of the left ear involving the helix, antihelix, scapha, and conchal bowl.

Sarcoma de Kaposi en región oral y maxilofacial, una neoplasia olvidada / Kaposi's sarcoma in the oral and maxillofacial region: a forgotten neoplasia

El VIH-sida es un problema de salud pública en el mundo. En 2014 se notificaron 9.888 casos nuevos en México y se estima que la mitad de los pacientes desconocen ser portadores de la enfermedad. El sarcoma de Kaposi asociado a sida (SK-sida) es un marcador de progresión de la enfermedad y de inmunosupresión. Aunque la incidencia de SK-sida en la cavidad bucal ha disminuido notablemente desde el acceso universal al tratamiento retroviral altamente activo, existen estudios en la Ciudad de México que establecen una incidencia de esta neoplasia en un 5%. El síndrome de reconstitución inmunológica asociado al SK-sida y linfoedema facial es una complicación potencialmente mortal. La falta de entrenamiento en el diagnóstico bucal del SK-sida y su relativa baja incidencia pueden hacer que para el clínico pase desapercibida esta neoplasia en el examen de rutina, siendo este un signo clínico característico de inmunosupresión. En este artículo se realiza una revisión del SK bucal asociado al sida (AU)

HIV-AIDS is still a worldwide public health problem. In 2014, 9,888 new cases were reported in Mexico, and it is estimated that half of those patients are unaware they suffer the disease. Kaposi's sarcoma associated with AIDS (KS-AIDS) is an indicator of the progression of this disease and immunosuppression. Although the incidence of KS-AIDS in the oral cavity has drastically decreased since the universal access to highly active antiretroviral treatment, several studies in Mexico City have reported an incidence of this neoplasia of 5%. The immune reconstitution syndrome associated with KS-AIDS and facial lymphoedema is a potentially life-threatening complication. Lack of training in the diagnosis of KS-AIDS, as well as its relatively low incidence, may cause this neoplasia to go unnoticed by the clinician, this being a clinical sign of immunosuppression. This article presents a review of oral KS associated to AIDS (AU)
