[The use of ECT for epileptic patient]

FARKAS Márta, BARAN Brigitta, KÁRPÁTI Róbert, RAJNA Péter

[Psychiatric disorders which indicate the use of electroconvulsive therapy (ECT) also occur in epileptic patients, but there is a lack of medical authority concerning the use of ECT in epileptic patients. This is surprising because in recent years it has been proved that ECT has an anti-convulsive effect to some degree. A case study of an epileptic patient is presented whose progress has been monitored for several years. Antiepileptic drugs were seemingly able to control his epilepsy but at the same time progressive behavioural disturbance (schizophreniform psychosis) accompanied by agitation and violent behaviour developed. Considering the recurrent psychotic decompensations and the relative ineffectiveness of antipsychotics, the authors decided to administer ECT. As a result they were able to bring about the longest symptom free balanced period in the patient. According to the data based on previous medical studies and the experience they can suppose that ECT is not immediately contraindicated by the presence of epilepsy with active interictal focus if the psychopathological condition makes it necessary. In view of the epileptogenic risk factors of classical neuroleptics, the epileptogenic effects of accompanying psychosis and the probable anticonvulsive potential of ECT in cases of severe psychiatric complications accompanying epilepsy ECT could be used more frequently.]

[The efficacy of autologous free fat graft and Spongostan in preventing postmicrodiscectomy scar formation]

LAPIS István, HORVÁTH Gyõzõ

[Introduction - Postoperative scar formation has been implicated as one of the possible cause of persistent or recurrent pain after spine surgery. The efficacy of the autologous free fat graft and the Spongostan gel foam for the prevention of extradural adhesion after lumbar discectomy was investigated by the evaluation of postoperative neurological symptomps and visual analogue scale. Patients and methods - In the study 174 patients were involved, average 14.5 months after the intervention. Autologous free fat graft (group I) and Spongostan gel foam (group II) was used randomly by the operations. Patients were operated by the same surgeon, and they were investigated by another independent surgeon. Result - No significant difference was found between the two groups.]

[The role of transcranial magnetic stimulation in clinical diagnosis: facial nerve neurography]

ARÁNYI Zsuzsanna, SIMÓ Magdolna

[Facial nerve neurography involving magnetic stimulation techniques can be used to assess the intracranial segment of the facial nerve and the entire facial motor pathway, as opposed to the traditional neurography, involving only extracranial electric stimulation of the nerve. Both our own experience and data published in the literature underline the value of the method in localising facial nerve dysfunction and its role in clinical diagnosis. It is non-invasive and easy to perform. Canalicular hypoexcitability has proved to be the most useful and sensitive parameter, which indicates the dysfunction of the nerve between the brain stem and the facial canal. This is an electrophysiological finding which offers for the first time positive criteria for the diagnosis of Bell’s palsy. The absence of canalicular hypoexcitability practically excludes the possibility of Bell’s palsy. The technique is also able to demonstrate subclinical dysfunction of the nerve, which can be of considerable help in the etiological diagnosis of facial palsies. For example, in a situation where clinically unilateral facial weakness is observed, but facial nerve neurography demonstrates bilateral involvement, etiologies other than Bell’s palsy are more likely, such as Lyme’s disease, Guillain-Barré syndrome, meningeal affections etc. Furthermore, the technique differentiates reliably between peripheral facial nerve lesion involving the segment in the brain stem or the segment after leaving the brainstem.]

[Hormonal abnormalities caused by intrasellar persistent trigeminal: PTA with hormonal dysfunction]

OSZTIE Éva, CZIRJÁK Sándor, RÁCZ Károly, MARTOS János

[Persistent trigeminal artery is a relatively frequent type of intracranial arterial developmental anomalies. The diagnostic tools for demonstration previously consisted of carotid angiography, later CT and DSA and nowadays MR and MRA. The practical benefit of the diagnosis is to avoid any hazard at the operation of associated hypophysis adenomas and aneurysms and could also give a possible explanation for apparent hormonal abnormalities. The authors support the latter possibility with a case report.]
