RESUMEN
Seven-hundred-two needle aspirates were taken from palpable lymph nodes between january 1982 and june 1987. Cytohistological correlation in about 70% of the preparations showed that the technique is capable of detecting neoplastic cells in 99% of metastases and in 90% of lymphoma cases. Certain technical aspects of smear preparation are pointed out with a view to reducing the percentage of inadequate samples (14% in the present series) and the position of the technique among other diagnostic procedures is discussed, with evaluation of advantages and limitations.

Serologic HLA typing was carried out on 71 seropositive and 40 seronegative patients with rheumatoid arthritis and compared with values in 134 normal controls. A significant increase of HLA DR4 antigen, compared with control values, was found only in seropositive rheumatoid arthritis; HLA A1 and B35 antigens were significantly increased in seronegative rheumatoid arthritis patients (p less than 0.05), when compared with control values, but only HLA A1 antigen remained significantly higher when the p-correct test was performed.
