RESUMO
Acid phosphatase staining is performed on cerebrospinal fluid cells of 365 samples from 105 patients with various types of meningitis. This enzyme activity is strongly positive in the early samples of bacterial meningitis, as far as the patients had not received a pretreatment with antibiotics for more than 24 h. It allows monitoring the response to therapy in subsequent samples. Acid phosphatase activity is positive in 2 cases of cryptococcus meningitis. It is negative in all cases of aseptic and Mycoplasma pneumoniae meningitis. The results in herpes encephalitis are variable, depending on the clinical state and the degree of brain destruction. Acid phosphatase staining is a useful and rapid cytological technique for determination of the nature of the meningitis and for monitoring the therapeutical response.

In three treated patients with a generalized invasion by a tumor of the lymphoid-hemopoietic systems, the neuropathologic findings were consistent with Wernicke's encephalopathy. The clinical picture was atypical, but thiamine deficiency by severe malabsorption was the probable cause of this neurologic complication. It is postulated that the chronic form of Wernicke's encephalopathy must occur more frequently than previously shown in treated and long-standing cases of such kinds of tumors.
