The reported prevalence of prostatic adenocarcinoma (PCa) in adults represents only the . The present retrospective study was carried out to estimate the prevalence of the silent PCa in 165 subjects (median age: 69 years; range: 40-82) undergone radical cystoprostatectomy for bladder cancer. To this aim, 38 subjects had routinely prostatic sampling by histology (group A), whereas 127 had systematic pathological sampling of the gland (group B). Silent PCa was diagnosed in 17 subjects (9.7%): 1 subject was in the group A (0.7%) and 16 were in the group B (9%). The data suggest that systematic examination of the prostatic specimens should be performed in order to approach the real prevalence of silent PCa in adult population.

[Temporal post-traumatic epilepsy: corticographic and ultrastructural study of a case].

A case of post-traumatic temporal epilepsy, submitted to a temporal lobectomy, is reported. During surgery, electrocorticography was carried out in order to differentiate epileptic areas from normal tissue. The ultrastructural study of nervous tissue removed from both normal and epileptogenic areas showed diffuse and aspecific process of neuronal alterations without a correlation to the electrographic epileptic areas. The importance of trauma in the evolution of these alterations is discussed.

[Usefulness of ambulatory EEG in detecting critical and intercritical events in patients with epilepsy or with suspected epilepsy].

Ambulatory EEGs (EEGAs) were recorded in 251 patients. In 91 of these patients there was a suspicion of having epileptic seizures, in 117 a diagnosis of epilepsy was already established, in 43 the withdrawal of antiepileptic drugs was envisaged being apparently free from seizures for years. The EEGA showed epileptogenic abnormalities in 31% of patients of the first group. This percentage was not far from the one obtained with standard EEG (EEGS) recordings. In the second group, a divergence was found, as for the classification of seizures, between the ictal events actually recorded on the EEGA and the definition of seizures based on clinical information. Furthermore ictal events recorded by the EEGA were less frequent than one would have anticipated according to the seizure frequency asserted by the patients. In the third group the EEGA disclosed the persistence of epileptic seizures, mostly represented by diffuse spike and wave discharges, in about 30% of the patients. Finally, comparison of the results obtained by the EEGA with those obtained by the EEGS in all patients suggested that the two recording techniques are complementary.
