Sentinel lymph node in endometrial cancer.

The aim of this study was to evaluate the possibility of identifying the sentinel lymph node and involvement of neoplastic cells in patients with endometrial carcinoma limited to the uterus, and also its correlation with the conditions of other pelvic and para-aortic lymph nodes. Forty patients with endometrial carcinoma, clinical staging I and II, were submitted to complete surgical staging through laparotomy, as recommended by FIGO in 1988. The sentinel node was investigated using patent blue dye in the myometrial subserosa. The sentinel node was excised and submitted to frozen section examination of specimen, stained with hematoxylin and eosin (H&E). Afterward, selective bilateral para-aortic and pelvic lymphadenectomy, total hysterectomy with bilateral salpingo-oophorectomy were performed. The lymph nodes excised were examined by means of paraffin-embedded slices stained with H&E and of imunohistochemistry with antikeratin antibody AE1/AE3. The sentinel lymph node was identified in 77.5% of patients (31/40), and 16.1% (5/31) presented neoplastic involvement in the node. In 25 cases of negative sentinel node, 96% (24/25) had no neoplastic involvement, and 4% (1/25) had other lymph node affected (false negative). In nine cases with no sentinel node identified, 55.5% (5/9) had lymph node involvement. The results of this study allow us to conclude that it is possible to identify the sentinel node using the methods described, and the pathologic examination significantly represents the same conditions of other pelvic and para-aortic lymph nodes.

Infecção pelo citomegalovirus em pacientes com sindrome da imunodeficiencia adquirida (AIDS): relacoes clinico-virologicas e anatomopatologicas / Infection by cytomegalovirus in patients with acquired immunodeficiency syndrome (AIDS): clinical, virological and histopathological correlations

Com o objetivo de determinar a prevalencia da infeccao pelo Citomegalovirus (CMV) em pacientes com AIDS, bem como relacionar os achados clinicos virologicos decorrentes desta infeccao com as repercussoes anatomopatologicas, estudamos 50 pacientes adultos atendidos entre abril de 1986 a junho de 1987, em dois hospitais publicos de Sao Paulo (HSP e HSPE). Estes pacientes foram acompanhados clinica e laboratorialmente, por periodo medio de 2 meses com coletas seriadas de sangue, urina e saliva. Foram realizados isolamento do CMV em monocamadas de fibroblastos humanos e testes sorologicos de Imunofluorescencia Indireta (IFI-IgG/IgM) e Reacao Imunoenzimatica (ELISA-IgG). No momento da admissao no estudo 20 por cento (10/50) dos pacientes apresentavam anticorpos IgM CMV especificos e 100 por cento (50/50) deles anticorpos IgG (IFI). Durante o acompanhamento, 5 pacientes inicialmente IgM negativos tornaram-se IgM positivos, sugerindo reativacao ou reinfeccao pelo CMV. O CMV foi isolado de sangue periferico em 12,5 por cento, da urina em 23,2 por cento, da saliva em 21,9 por cento dos pacientes. Exames anatomopatologicos foram realizados em 24 pacientes, correspondendo a 60 por cento dos pacientes que evoluiram para obito durante o periodo de estudo...
