Clinical Neuroscience - 2005;58(01-02)

[Background - Less than 1.2% of papers published in the first 50 volumes of the journal Clinical Neuroscience/Ideggyógyászati Szemle - the major official journal of Hungarian neurologists - focused on headache despite the fact that headache is among the most frequent complaints in neurological consultations. In the current study the authors evaluated the presence of headache as the main topic in articles of the Hungarian medical literature. Methods - They identified full publications on headache by handsearching all volumes of the journal Clinical Neuroscience/ Ideggyógyászati Szemle from 1950 till the end of 2003. Electronic searches were performed to find Hungarian papers focusing on headache using the bibliographic databases of the Hungarian National Library of Healthcare (Hungarian Medical Bibliography, HMB) and the American National Library of Medicine of the National Institutes of Health (Medline and Oldmedline). Results of handsearch and electronic searches were cross checked for the journal Clinical Neuroscience/Ideggyógyászati Szemle. Results - Of the 2618 full papers published in Clinical Neuroscience/ Ideggyógyászati Szemle headache was the main topic in 32 articles (1.2%), most of them published after 1985. The electronic search of the HMB resulted in 132 documents in 41 journals, whereas using the PubMed search engine, they identified 66 Hungarian papers on headache. Migraine was the most frequent topic of interest in papers found by all three searches. The HMB search identified all headache articles published after 1990 in Clinical Neuroscience/Ideggyógyászati Szemle which were identified by handsearch. The Oldmedline, database contained four of the seven papers identified by handsearch from 1954-1964. After 2002, the start of indexing Clinical Neuroscience/Ideggyógyászati Szemle in the Medline, the only article identified by handsearch was also found by the electronic search. Conclusion - After the lack of interest until the mid-1980-ies, headache became a frequent topic in the Hungarian medical literature. Bibliographical data of articles on headache published after 1990 can be identified by electronic searches of the Hungarian and international bibliographic databases using carefully constructed but simple search strategies. An increasing presence of Hungarian headache research was found in international journals in the last two decades.]

[DIZZINESS - VERTIGO WARNING SYMPTOMS IN VERTEBROBASILAR ISCHEMIA PART II.]

FAZEKAS András

[Dizziness and vertigo - like headache - are the most common complaints which lead patients to visit the doctor. In spite of the headache - which may be primary (e.g. migraine) or symptomatic - dizziness and vertigo do not appear to be a separate nosologic entity but rather the symptoms of several neurological disorders. For differential diagnosis, interdisciplinary thinking and activity is needed because the vestibular, neurological and psychiatric disorders might have a common role in the development of symptoms and further overlapping can also occur. The vascular disorders of the vertebrobasilar system are discussed in detail in this review. The importance, occurrence and causes of vertigo as a warning symptom is in the focus. The author draws attention to life-threatening conditions with acute onset in cases of the posterior scale ischemia and emphasizes the importance of the correct and early diagnosis. The author tries to clear up the nihilistic aspect in treating of stroke and stresses the necessity of thrombolysis and interventional radiological procedures which may be the only chance for the recovery of the patients. The pharmacological prevention of recurrent vascular events is also important and obligatory for the clinicians.]

[CHRONIC INFLAMMATORY POLYNEUROPATHIES]

BENICZKY Sándor, VÉCSEI László

[There is an increasing number of peripheral nerve disorders with inflammatory and immune mechanisms involved. The precise diagnosis is of utmost importance, since these patients can be successfully treated. Unfortunately, there is no specific marker for any disease of this group. The diagnosis therefore relies on the appropriate consideration of the clinical, neurophysiological and laboratory data, which requires in-depth knowledge of these diseases. In this paper we review the diagnostic criteria and treatment strategies for the major types of chronic inflammatory polyneuropathies.]

[THE PERISYLVIAN EPILEPTIC NETWORK A unifying concept]

HALÁSZ Péter, KELEMEN Anna, CLEMENS Béla, SARACZ Judit, ROSDY Beáta, RÁSONYI György, SZŰCS Anna

[In this work the authors provide evidences for a unifying concept of the syndromes of benign focal childhood epilepsies, Landau-Kleffner syndrome, and electrical status epilepticus in sleep treating them as a spectrum of disorders with a common transient, age dependent, non lesional, genetically based epileptogenic abnormality, the nature of which is still not known. The electro-clinical features of these syndromes are congruent with the different degree involvement of the perisylvian cognitive network and with the involvement of the thalamo-cortical associative system of variable degree. These epilepsies are characterized by the abundance of regional epileptiform discharges in sharp contrast with the rare and in several cases lacking seizures. The nature and severity of interictal cognitive symptoms are closely related to localization within the network and amount of epileptic interictal discharges. Spike-wave discharges are attributed to an alternation of overexcitation (spikes) and overinhibition (waves). The recurrent overinhibition represented by the wave of the discharges may interfere with the continuous depolarization of the cells of a large population of neurons, which is a requirement of the overt seizures. The overinhibition also interfere with cognitive processes which are correlated with the continuous presence of the fast (gamma) activity, binding the required cortical areas. Hence the recurrent inhibition works against the existence of the binding fast frequency activity. This is the assumed reason for the co-existence of the relative lack of overt seizures and in the same time for the frequently observed epileptogenic cognitive deficit symptoms ("cognitive epilepsies"). The time course of these syndromes overlaps with important developmental milestones. The frequent epileptic discharges alters the evolution of the perisylvian network developing late after early childhood and is very vulnerable for any interference in this imprinting time for speech and other cognitive functions. This spectrum of disorders represents a type of age linked, mild to severe ‘epileptic encephalopathy’ limited to the perisylvian network, where the cognitive impairment is underlied by epileptic discharges interfering with cognitive development.]

[EXAMINATION OF NATURAL COAGULATION INHIBITOR PROTEINS IN THE ACUTE PHASE OF ISCHAEMIC ST]

OLÁH László, CSÉPÁNY Tünde, BERECZKY Zsuzsanna, KERÉNYI Adrienne, MISZ Mária, KAPPELMAYER János, CSIBA László

[Introduction - Decreased activity of natural anticoagulants (antithrombin-III, protein C, protein S) rarely causes cerebral ischaemia, however it can be found frequently in acute phase of ischaemic stroke. The authors’ aim was to investigate whether the decreased activity of natural anticoagulants is accompanied by worsening of symptoms in ischaemic stroke. Patients and method - Sixty-eight acute ischaemic stroke patients were investigated. Severity of symptoms were assessed and followed by the NIH Stroke Scale. Antithrombin- III, protein C, protein S activities, and concentration of C-reactive protein (CRP) were measured within 48 hours after onset of ischaemic stroke. Results - Progressing stroke was found in 29% of patients. Decreased activity of at least one natural anticoagulant proteins was present in 31% of patients. Progression of stroke symptoms occured in 76% of patients with decreased natural anticoagulant activity, while this proportion was only 9% in those with normal natural coagulation inhibitor protein activity (p<0.01). Progressing stroke was also more frequent in patients with elevated CRP value (60%) than in those with normal CRP level (11%; p<0.05). Decreased activity of natural anticoagulants was more frequent in patients with elevated CRP concentration compared with patients with normal CRP. Conclusion - The results demonstrate the importance of decreased activity of natural anticoagulants in acute phase of ischaemic stroke. This abnormality was present in about 1/3 of stroke patients. The decreased activity of natural coagulant inhibitor proteins may play an important role in development of progressing stroke thus indicating unfavourable outcome.]

[EXPERIMENTAL DEMYELINATION CAUSED BY PRIMARY OLIGODENDROCYTE DYSTROPHY Regional distribution of the lesions in the nervous system of mice brain]

KOMOLY Sámuel

[Background and purpose - Heterogeneity of multiple sclerosis lesions has been recently indicated: In addition to T-cell-mediated or T-cell plus antibody-mediated autoimmune mechanisms (patterns I-II) two other patterns (III-IV) were described. Patterns III-IV are characterized by primary oligodendrocyte dystrophy, reminiscent of virus- or toxin-induced demyelination rather than autoimmunity. It was described more than 30 years ago that dietary application of a copper-chelating agent called cuprizone results in primary oligodendrocyte degeneration which is followed by demyelination. The aim of the present study was to examine the regional distribution of cuprizone induced oligodendrocyte dystrophy and demyelination in the nervous system of mice. Material a methods - Demyelination was induced in male weanling Swis-Webster mice by feeding them on a diet containing 0.6% (W/W) cuprizone bis(cyclohexanone)-oxalyldihydrazone (G. F. Smith Chemical, Columbus OH) for 8 weeks. Animals were sacrificed after 3, 7, 14, 27, 35, 56 days of cuprizone administration. Samples were taken from corpus callosum, anterior commissure, optic nerve, cervical spinal cord and sciatic nerve. Samples were examined by immunohistochemistry, in situ hybridization for myelin proteins and myelin protein mRNA-s, respectively. Conventional neuropathological stainings and electron microscopy was also performed. Results - Oligodendrocyte degeneration and demyelination followed a particular standard pattern in the central nervous system. Profound myelin loss developed in the superior cerebellar peduncle, anterior comissure and corpus callosum, whereas the optic nerves, velum medullare anterior and spinal cord showed little or no demyelination. Sciatic nerves were unaffected. No infiltration by lymphocytes or blood-brain barrier damage was observed during cuprizone treatment. Conclusion - Cuprizone induced oligodendrocyte damage and demyelination follows a particular standard pattern in the central nervous system of mice. Cuprizone induced demyelination might be considered as a model for human demyelinating disorders with primary oligodendrocyte dystrophy and apoptosis.]

Acute effect of sphenopalatine ganglion block with lidocaine in a patient with SUNCT

KOCATÜRK Mehtap, KOCATÜRK Özcan

Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing/short-lasting unilateral neuralgiform headache with cranial autonomic features (SUNCT/SUNA) is a rare severe headache. At the time of an attack, it can hinder a patient from eating and requires acute intervention. The sphenopalatine ganglion is an extracranial parasympathetic ganglion with both sensory and autonomic fibers. Sphenopalatine ganglion block has long been used in the treatment of headache, particularly when conventional methods have failed. Here, we present a patient who was resistant to intravenous lidocaine, but responded rapidly to sphenopalatine ganglion block during an acute episode of SUNCT/SUNA.

Medication overuse headache: The effectivity of iv lidocaine – magnesium

TEPE Nermin, TERTEMIZ Faysal Oktay

The detoxification process in medication overuse headache is the most difficult process for the patient. We aimed to investigate the effectiveness of the combination of low dose IV lidocaine and magnesium (100 mg lidocaine and 1.25 mg magnesium) in patients with medication overuse headache during the detoxification process. A total of 30 patients were included in the study; 15 received 24 hours of IV hydration, 15 received 1-hour lidocaine-magnesium infusion at the onset of pain in addition to the 24 hours of IV hydration. Headache severity (numeric rating scale, NRS), attack durations, onset of headache, monthly analgesic/triptan intakes, numbers of monthly headache days data were documented. We evaluated the severity of headache before and after daily treatment of two groups for one week. When both groups were compared, there was no significant difference in the pre-treatment NRS values, whe­reas, in the group receiving IV lidocaine-magnesium combination, there was a statistically significant decrease in the post-treatment NRS values in the first five days (p <0.05). An 1-hour combined infusion of lidocaine-magnesium may be considered as an alternative option for the patient to have a more quality detoxification process during the hospital stay, so that in parallel to the reduction in the use of multiple treatments (such as neuroleptics, benzodiazepines, antiemetics and opioids) and duration length of stay, the economic costs can also be reduced. The administration of combination will bring fewer side effects compared to their administration separately.

To handle the HaNDL syndrome through a case: The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis

ÇOBAN Eda, TEKER Ruken Serap, SERİNDAĞ Helin, SAKALLI Nazan, SOYSAL Aysun

The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis (HaNDL) is a rare entity. This disease has been related to migrainous headaches. It is a benign, self-limited disorder, which is characterized by fluctuating neurological symptoms and cerebrospinal fluid lymphocytosis. We describe a case of a 47 years old man with acute onset of headache and aphasia. Cerebrospinal fluid analysis revealed a lymphocytic pleocytosis (25 cells/μl, 100% lymphocytes). Electroencephalogram showed moderate slow rhythm in the left hemisphere, with temporoparietal predominance, and without epileptiform activity. His blood tests as well as magnetic resonance imaging (MRI) results were normal. With the diagnosis of HaNDL syndrome the patient was accepted in the Department of Neurology and discharged with full recovery.

[HEADACHE IN EVERYDAY MEDICAL PRACTICE]

ERTSEY Csaba

[Headache is one of the most common complaints in clinical practice. The International Headache Society’s current classification distinguishes two major categories of headache: primary and secondary (symptomatic) headache types. The former types, which account for the majority of headaches, are caused by a functional disorder in a structurally intact nervous system and are characterised by stereotypical attacks that resolve - in most cases - spontaneously after a certain period, the duration of which is characteristic for each headache type. The diagnosis of primary headaches is based on a detailed history of the attacks and negative results on a neurological examination. At the first presentation of the patient, it should be determined whether a potentially serious or life-threatening condition might be present, whether the type of the patient’s headache can be ascertained according to the IHS’s criteria, and what kind of examinations are needed to establish the correct diagnosis. A detailed history is the cornerstone of the diagnosis of primary headaches and it cannot be substituted by instrumental examinations. The use of imaging and other examination methods is necessary for the diagnosis of secondary headaches, but if the patient’s history and the results of the neurological investigation are fully consistent with a primary headache type, instrumental examinations are unlikely to provide any additional information. Although establishing the correct diagnosis is often time-consuming, it is necessary for the efficient treatment.]
