[Interictal EEG coherence in patients with partial temporal lobe epilepsy].

Aims: The purpose of this research was to study the spatio-temporal characteristics of the correlation that exists between two simultaneous EEG signals (coherence) in the interictal period in patients with partial epilepsy that is presumably symptomatic of the temporal lobe (ILAE).

Patients And Methods: A study of 13 patients, aged between 17-60 years, was conducted (53% females). A digital EEG was performed on each patient using the 10/20 system of electrode location.

[Cryptococcosis of the central nervous system. A report of five cases].

Introduction: Since the 1980s, in relation to the spread of AIDS, there has been an enormous increase in cryptococcosis, a mycotic disorder which usually affects the central nervous system (CNS). This disease is caused by Cryptococcus neoformans, a microorganism acquired by inhalation of bird excrement. This germ produces a capsule which protects it from phagocytosis, can synthesize melanin which acts as an antioxidant of the cytotoxic lymphocytes and can reproduce at body temperature.

[Neurological Behcet syndrome. Presentation of three cases].

Introduction: Behçet's disease is a multisystemic illness in which neurological abnormalities are seen in 5-48% of cases.

Clinical Cases: We present 3 patients (2 men and 1 women) diagnosed as having Behçet's disease, according to the criteria of the 'International Study Group for Behçet's Disease' of 1990. We describe the clinical findings in these patients, the results of investigations done (MR or CT, evoked potentials-PEV, PESS, PEATC-EEG, ECN, CSF and neuropsychological tests), their course and response to treatment with hyperimmune human gammaglobulim at a dose of 400 mg/kg body weight in 2 patients.
