[Effect of phenytoin and carbamazepine on evoked potentials in patients with newly diagnosed epilepsy. Part II. Brainstem auditory evoked potentials].

Brainstem auditory evoked potentials (BAEPs) were studied in 64 untreated epileptics with partial (58) and primary generalized seizures (6). Patients were randomized to have either phenytoin (PHT) or carbamazepine (CBZ) monotherapy. Follow-up recordings were made 3 months after PHT (21) or CBZ (22) monotherapy in 43 patients with partial seizures.

[Effect of phenytoin and carbamazepine on evoked potentials in patients with newly diagnosed epilepsy. Part I. Visual evoked potentials].

Pattern-reversal visual evoked potentials (VEPs) were recorded in 64 patients with newly diagnosed epilepsy. Before starting medication the patients with partial and primary generalized epilepsy, had prolonged latencies of the VEPs component P100, as compared with controls. VEPs were repeated after 3 months in 43 patients with focal epilepsy, during carbamazepine (22 cases) or phenytoin (21 cases) treatment.

[Effect of hemodialysis on somatosensory evoked potentials of medium and long latency].

In 16 patients with terminal renal failure aged from 21 to 74 years maintained on haemodialysis programmes for 2 to 60 months somatosensory evoked potentials were studied after stimulation of the median nerve immediately before and after haemodialysis. The central conduction time, the P 45-N 60, P 100-N 140-P 200 complexes and the P 300 wave were evaluated. The results were compared with those in 16 healthy volunteers aged 20 to 66 years.

Creutzfeldt-Jakob disease in young people.

Three neuropathologically confirmed cases of Creutzfeldt-Jakob disease in young people (19, 23, and 27 years of age) are described. None had received pituitary hormone therapy. At the onset of illness all patients were suspected of having SSPE or other viral encephalitis, because of the similarity of clinical symptomatology and the shift towards older age of SSPE onsets observed in Poland in recent years.

[Surgically treated epidural hematoma of the spinal cord at the Th1-Th2 levels associated with arachnoid cyst].

In a man aged 28 clinical picture, myelography and computerized myelotomography demonstrated epidural haematoma at the level of Th1-Th2 vertebrae with associated arachnoidal cyst. Owing to initially erroneous diagnosis of transverse myelitis the haematoma was diagnosed only after 7 days and removed surgically with simultaneous evacuation of the cyst. The therapeutic result was minimal.
