Caries temprana de la infancia: rehabilitación estética, funcional e integral en paciente preescolar. Caso clínico / Early childhood caries: esthetic, functional and comprehensive rehabilitation in preschool patient. A clinical case

La American Academy of Pediatric Dentistry (2020) define a la caries temprana de la infancia (CTI) como una forma severa de caries de etiología multifactorial que compromete la dentición primaria de niños pre-escolares. Afecta principalmente a los incisivos primarios superiores seguidos de los primeros molares primarios, pudiendo promover el desarrollo de hábitos parafuncionales, reducción de la eficacia masticatoria, pérdida de la dimensión vertical, alteraciones en la fonación y defectos estéticos que causan repercusiones emocionales e impacto psicosocial. La insuficiente cantidad y calidad de estructura coronaria remanente, luego de la eliminación del tejido cariado, puede comprometer la adhesión de los materiales de restauración. El objetivo de este trabajo es presentar la atención y el seguimiento a dos años de un paciente preescolar que presenta CTI, que concurrió para su atención a la Cátedra de Odontología Integral Niños de la Facultad de Odontología de la Universidad de Buenos Aires (AU)

Results of liver transplantation at the Cuban Center for Medical and Surgical Research.

From July 4, 1999, when a liver transplantation program was started in Cuba, to December 30, 2007, we performed 125 procedures in 115 patients. The most frequent reasons for transplantation were cirrhosis caused by hepatitis C virus (29%) and alcoholic cirrhosis (17.2%). Two patients received simultaneous liver-kidney transplants. Sixty-seven patients were males, and the patient ages ranged from 12 to 74 years. The average surgical time was 6 hours, and cold ischemia time was 4 to 14 hours. The average blood consumption was 1630 mL; 2900 mL of plasma and 8 units of platelets were used in 7 cases. Immunosuppression was mainly cyclosporine, mycophenolate mofetil, and prednisone. Acute cellular rejections were treated in almost all cases with 3 doses of methylprednisolone. The most frequent complications were biliary (15%), hepatic arterial thrombosis (6%), postsurgical bleeding (8%), acute cellular rejection (20%), and ductopenic rejection (2%). The overall 1-year survival was 74.7%.
