Acute Promyelocytic Leukaemia. Relationship of Cytochemical Pattern with Clinical, Morphologic and Immunological Characteristics, and Outcome.

In a series of 61 acute promyelocytic leukemia (APL) cases multiple clinical and biological characteristics were studied in order to assess their prognostic significance and to evaluate the relationship of cytochemical pattern with clinical, morphologic, and immunological characteristics and outcome. Alpha-naphthyl acetate esterase (ANAE) activi1:y was expressed in 23 out of 41 cases (56%). Sodium fluoride-sensitive naphthol AS-D acetate esterase was evident in only one out of 22 cases (5 %).

[Listeriosis in the adult: presentation of 14 cases].

The incidence of Listeria monocytogenes (LM) infection has increased in recent years, particularly in immunocompromised patients or in those with severe underlying diseases. However, it still is an unusual pathogen. In the present study we report 14 cases of listeriosis in adults, seen from 1978 to 1988.
