ABSTRACT

Objetivo: Evaluar la tendencia del uso de la cirugía convencional (CC) y la vitrectomía por pars plana (VPP) en el tratamiento del desprendimiento de retina regmatógeno (DRR) primario, y determinar los resultados anatómicos y funcionales obtenidos mediante estas dos técnicas. Métodos: Estudio retrospectivo de 100 ojos de 78 pacientes con DRR primario operados durante el año 2003 en la Fundación Oftalmológica Los Andes de Santiago, mediante CC o VPP. Resultados: La VPP se utilizó en el 63 por ciento de los casos y la CC en el 37 por ciento. Con una cirugía, se logró reaplicar la retina en el 83,8 por ciento con CC y en el 87,3 por ciento con VPP, diferencia no significativa (p > 0,05). Tampoco hubo diferencia significativa en la ganancia de AV entre u otra técnica. Conclusión: Existe una mayor tendencia a operar el DRR primario mediante vitrectomía. No existen diferencias anatómicas ni funcionales en el resultado postoperatorio entre ambas técnicas.

ABSTRACT

We report a 11 years old male diagnosed as a X-linked hyper-IgM syndrome that presented with recurrent infections and sclerosing cholangitis and later developed a gallbladder cancer. Immunological evaluation showed decreased levels of serum IgG and IgA with elevated levels of IgM. Study of CD40 ligand expression on mitogen activated peripheral blood mononuclear cells revealed total absence of this marker on T lymphocytes. Molecular analysis detected, in the patient and his mother, a nonsense mutation in exon 1 of the transmembrane segment of the CD40 ligand. He also presented elevation of alkaline phosphatases and mild elevation of liver enzymes. Liver biopsy demonstrated the presence of idiopathic sclerosing cholangitis. The patient was started on monthly IVIG therapy at 400 mg/kg, as well as ursodeoxycholic acid and vitamin E, with normalization of his IgG and IgM levels a decrease in the incidence of infections and normalization of liver function. Three years after diagnosis, we detected the presence of polyps inside the gallbladder that were reported at biopsy as adenocarcinoma. He underwent hepatic bisegmentectomy (VI B-V) and local lymphadenectomy
