[The authors present the case history of a 68-years­ old female patient. The patient, who is known to have hypertension, developed on the day of her admission a short lasting loss of consciousness. Upon recovery the following neurological symptoms were observed: gaze paresis upward and to the right, skew deviation, partial gaze paresis downward, slight right sided hemipares is, ataxia of the right extremities and trunk, right sided hemihypesthesia. Short neuropsychological examination disclosed a speech disorder and the disturbance of abstract thinking. CT scan of the brain showed a congenital arachnoidal cyst in the region of midline cerebellar structures, ischemic infarcts in the right cerebellar hemisphere and in the medial part of the left thala­mus. MRI in addition revealed a 2-3 mm large infarct in the mesencephalon. MR angiography showed a tortuous basilar artery. Neuro-ophthalmological examination and acoustic evoked potentials indicated a functional disturbance at the right side of the brainstem at the level of the pons and midbrain. The authors present a case with a thalamic infarct accompanied by a complex eye movement disorder and cerebellar symptoms. They wish to indicate the role of thalamic infarcts in the development of a sud­den loss of consciousness with successive neuropsy­chological disturbance and gaze palsy.]

[Repeated stroke, psychotic episode - primary antiphospholipid syndrome?]


[The antiphospholipid syndrome described some 10 years ago is characterized by a predisposition to arterial and venous thrombosis and the presence of antiphospholipid antibodies. It is often associated with systemic lupus erythematosus, but its primary forms are also well known. Its clinical features are well known in neurology as well as in psychiatry. In this paper we present a case report with therapeutic implications. We discuss the importance of reccurent stroke at a young age in association with the possibility of a rare manifestation of antiphospholipid syndrome: organic brain disease, appearing in the form of schizoaffective psychopathological symptoms.]

[Cluster headache and its treatment]


[Cluster headache, one of the most painful conditions known, is encountered infrequently in clinical practice. It is characterized by recurrent, unilateral attacks of severe intensity, brief duration and often accompanied by signs and symptoms of autonomic dysfunction. The actual cause of the pain has not been fully elucidated, but most authors believe that the pain arises as a result of a local vasodilatation with a release of certain neuropeptides to the perivascular tissues, resulting in sterile neurogenic inflammation and oedema. Aetiology is absolutely unknown. Treatment can be given as prophylaxis and/or as a symptomatic acute therapy for individual attacks. In the prophylaxis of episodic cluster headache ergotamine, calciumentry blockers, serotonin inhibitors and steroids are used. In chronic cluster headache lithium is the drug of choice, but verapamil may also be tried. Acute therapy has included ergotamine, oxygen inhalation and sumatriptan. Rarely, surgical intervention may be considered.]

[Experiences with sumatriptan in the treatment of Cluster headache]


[Subcutaneously administered sumatriptan 6 mg is rapid, effective and well-tolerated for the acute treatment of cluster headache. Efficacy is maintained in long-term use. The authors report the results of the 5HT1 receptor agonist sumatriptan autoinjector in the treatment of 350 attacks in 20 cluster patients. After 20 minutes post injection the complete dissolution of headache was reported in 95% of the attacks. Slight and transient side-effects were experienced therefore non of the patients were discouraged from using the autoinjector device again. It is essential in the improvement of the quality of life of patients suffering from cluster headache.]

[Quantitative monitoring of EEG variability following subarachnoid hemorrhage]


[Cerebral vasospasm causing focal ischemia is a frequent complication following subarachnoid hemorrhage. Monitoring of EEG may help to reveal hemispheric dysfunction in the postoperative period. Continuous monitoring of EEG was performed on 8 bipolar channel in 30 patients with subarachnoid hemorrhage during the first two weeks after aneurysm rupture. Computerized trend analysis of 8–16 hours long periods was made. Variability of relative alpha power was evaluated visually on a 4 grade scale and it was also measured quantitatively. EEG data were compared with daily transcranial Doppler values and clinical state. Symptomatic vasospasm was detected in 16 patients while other neurological complications developed in a further 4 cases during monitoring. Significant decrease of variability was observed in all of them. This change developed 1-2 days before other signs of vasospasm in 10 patients. The onset of variability decrease was unilateral in 4 cases. No remarkable decrease of variability was found in patients without neurological complication. Our data confirm that EEG monitoring is a useful tool for sensitively detecting deterioration of brain function. Relative alpha variability is an indicative EEG parameter that can signify hemispheric dysfunction caused by ischemia in an early subclinical stage, when still no Doppler signs of vasospasm or deterioration of clinical symptoms occur.]

[Intravenous perfusion anaesthesia in neurosurgey part two]


[A retrospective analysis of 1300 neurosurgical perfusion narcoses performed by means of intravenously administered propofol-fentanyl-vecuron proved the advantage of this technique over traditional procedures. It decreased the recovery time, the incidence of postoperative nausea and vomiting, and muscle fibrillation. Propofol did not elevate either raised or normal intracranial pressures. Moreover, a trend reduction of raised ICP was observed. The incidence of cardiovascular complications was also reduced. Patients, especially the elderly, had a quick, subjectively well-tolerated induction of sleep and recovery. Comparison of parameters of propofol general anaesthesia with those of "combined balanced narcosis" and "perfusion ataranalgesia” statistically proved the significantly advantage of this new method. The conclusion has been drawn that propofol was a most appropriate drug for neurosurgical anaesthesia. ]

A case with reversible neurotoxicity induced by metronidazole

EREN Fulya, ALDAN Ali Mehmet, DOGAN Burcu Vasfiye, GUL Gunay, SELCUK Hatem Hakan, SOYSAL Aysun

Background - Metronidazole is a synthetic antibiotic, which has been commonly used for protozoal and anaerobic infections. It rarely causes dose - and duration - unrelated reversible neurotoxicity. It can induce hyperintense T2/FLAIR MRI lesions in several areas of the brain. Although the clinical status is catastrophic, it is completely reversible after discontinuation of the medicine. Case report - 36-year-old female patient who had recent brain abscess history was under treatment of metronidazole for 40 days. She admitted to Emergency Department with newly onset myalgia, nausea, vomiting, blurred vision and cerebellar signs. She had nystagmus in all directions of gaze, ataxia and incompetence in tandem walk. Bilateral hyperintense lesions in splenium of corpus callosum, mesencephalon and dentate nuclei were detected in T2/FLAIR MRI. Although lumbar puncture analysis was normal, her lesions were thought to be related to activation of the brain abscess and metronidazole was started to be given by intravenous way instead of oral. As lesions got bigger and clinical status got worse, metronidazole was stopped. After discontinuation of metronidazole, we detected a dramatic improvement in patient’s clinical status and MRI lesions reduced. Conclusion - Although metronidazole induced neurotoxicity is a very rare complication of the treatment, clinicians should be aware of this entity because its adverse effects are completely reversible after discontinuation of the treatment.

Insights into the structure and function of the hippocampal formation: Relevance to Parkinson’s disease

GYÖRFI Orsolya, NAGY Helga, BOKOR Magdolna, KÉRI Szabolcs

The link between the hippocampus and declarative memory dysfunctions following the removal of the medial temporal lobe opened unexplored fields in neuroscience. In the first part of our review, we summarized current theoretical frameworks discussing the role of hippocampus in learning and memory. Several theories are highlighted suggesting that the hippocampus is responsible for assembling stimulus elements into a unitary representation that later can be utilized to simulate future events. The hippocampal formation has been implicated in a growing number of disorders, from neurodegenerative diseases to atypical cognitive ageing and depression. Recent neuroimaging studies provided new opportunities to study in detail the hippocampal formation’s role in higher levels of the nervous system. We will present data regarding the regional specialization of the hippocampus in experimental models developed for healthy and neurological conditions with a special focus on Parkinson’s disease. Combined evidence from neuroimaging studies suggested that hippocampal volume is reduced in non-demented, newly diagnosed patients with Parkinson’s disease, which is associated with impaired memory performance. These findings proposed that, beyond the well-known striatal dopamine loss, impaired hippocampal synaptic plasticity may contribute to cognitive and affective impairments in early Parkinson’s disease.

[The significance of high-resolution ultrasonography in the diagnosis of peripheral nerve disorders]


[High resolution ultrasonography is an emerging technique for the investigation of peripheral nerves and is increasingly used worldwide in the diagnosis of peripheral nerve disorders, however, until now it is not widespread in Hungary. According to the literature this method is especially useful in entrapment neuropathies, traumatic peripheral nerve injuries, tumors of the peripheral nerves and sonographically guided interventions. Ultrasonography allows precise morphological analysis and quantitative measurements of the nerves providing useful complementary information to electrodiagnostic data. In entrapment neuropathies ultrasound shows nerve swelling mainly proximal to the sites of compression and a focal change of echotexture. On longitudinal scan, an abrupt caliber change and spindle-like swelling of the compressed nerve segment can be seen. Evaluation of the anatomical background and visualisation of the postoperative and posttraumatic changes provide useful information for planning of the therapy. Ultrasound may be of significant help in localizing the pathological nerve segment when it is at an electrophysiologically inaccessible site or when substantial secondary axonal loss precludes precise electrophysiological localization and it might even show pathological changes when nerve conduction studies are normal. Contrary to electrophysiological investigation ultrasonography might discover neurotmesis in the akute phase of traumatic nerve injuries indicating the necessity of surgical intervention. We provide a summary of the main indications and further application areas of this method.]

[Intraoperativ electrophysiological monitoring during neurosurgery on eloquent structures]

FEKETE Gábor, NOVÁK László, ERÕSS Loránd, FABÓ Dániel, BOGNÁR László

[Objective - We summarize our experiences on intraoperative electrophysiological monitoring during neurosurgical procedures on eloquent neuronal structures. Patients, methods - Sixty patients were enrolled retrospectively in our study with pathologies involving eloquent neuronal structures. They were operated between May 2011. and March 2012. at the University of Debrecen, Department of Neurosurgery and at the National Institute of Neurosciences. Patients underwent standard preoperative examinations due to the primary pathology. In all cases we used intraoperative electrophysiological monitoring. We had 22 cases with cranial nerve monitoring, 10 cases with cauda monitoring, 16 cases with motor system monitoring, six cases with complex spinal cord monitoring, three degenerative spine reconstructions and 3 awake surgeries. Results - We found that with the use of intraoperative electrophysiology we could make these neurosurgical procedures safer, and were able to optimize the extent of resection in the cases of oncological pathologies. Conclusions - Our experiences as well as the international literature suggests that in certain high risk neurosurgical procedures intraoperative electrophysiology is indispensible for safe and optimally extended operation.]

[Progressive myoclonus epilepsy - A review and case histories]


[Progressive myoclonus epilepsy (PME) syndrome is a heterogeneous entity underlain by rare genetic diseases. The most frequent origins of progressive myoclonus epilepsy are: Unverricht-Lundborg disease, Lafora's disease, ceroid lipofuscinosis, MERRF (myoclonus epilepsy with ragged red fibers) and sialidosis. Action myoclonic jerks, epileptic seizures, mental deterioration, neurological impairments are the four main symptoms of PME syndrome. Nowadays in more and more cases a causal diagnosis is possible in the PME syndrome. In this paper clinical data and findings of our 10 outpatients suffering from PME were analysed retrospectively. Electrophysiological, neuroimaging and histological examinations were performed. On the basis of the findings of the 10 patients 6 suffered from Unverricht-Lundborg disease, 1 from Lafora disease and 1 from MERRF In 2 patients we were not able to find specific diagnosis. Among our patients gypsy nationality occurs in a relatively large proportion and we know of more gypsy PME cases under care of other centres. It may raise the question whether Hungarian gypsies suffer from PME more frequently. This paper - to our knowledge – is the first study dealing with a group of PME cases in Hungary.]
