[INTRODUCTION - Central nervous system complications occur in 1% of patients with Mycobacterium tuberculosis infection, but the mortality is very high, about 50 percent. CASE REPORT - A 1-year-old child in tenebrous condition was admitted to the hospital with suspicion of meningitis. MRI detected disseminated encephalitis and dilated ventricles. Examination of the serum and cerebrospinal fluid didn’t bring any results. The microscopic examination of the brain biopsy raised the possibility of tuberculous meningoencephalitis, and the culture and PCR from the brain tissue revealed meningoencephalitis caused by Mycobacterium tuberculosis Beijing. DISCUSSION - Tuberculous meningitis is a very rare, but severe consequence of extrapulmonary tuberculosis. Due to the high mortality, early diagnosis and whenever suspected, the use of empiric antituberculotic therapy are the only chances of recovery.]

[Possibilites of modern, evidence based prevention of recurrent cystitis]

GANYECZ Máté, KÖVES Béla, TENKE Péter

[Recurrent cystitis is a very common disease in women; every second women experiences at least one episode of acute cystitis during their lifetime, and in 20% of the cases it develops to recurrent cystitis. The disease also has a significant negative impact on quality of life. In 60% percent of the cases mild-severe depression can be shown, which can be reduced by 30-40% with the properly chosen prophylaxis. Therefore the up-to-date knowledge of the evidence based recommendations on disease management is mandatory to all clinicans dealing with this patient group. In case of a recurrent urinary tract infection treatment of the actual episode is not enough. Rather, emphasis has to be placed on appropriate prevention strategy. Alway non-antimicrobial methods has to be preferred as first choice, antibiotic prophylaxis should be considered only when the non-antimicrobials have been unsuccessful. In this review the authors summarise the evidence based management options of recurrent urinary tract infections in detail, based on the guideline recommendations of the European Association of Urology. ]

[HISTOCHEMISTRY OF THE EXTRACELLULAR MATRIX IN THE SNAIL CENTRAL NERVOUS SYSTEM]

SERFŐZŐ Zoltán, ELEKES Károly

[Even tough the central nervous system (CNS) of gastropods has long been used as a model for studying different neuronal networks underlying behaviors, there is only little information on the molecular components of the extracellular matrix (ECM) of the nervous tissue. Therefore, the aim of the present study was to identify some of the ECM molecules by acid-base histochemistry. Staining with alcian blue at strong acidic pH, and with acridine orange at different pH and salt concentrations was carried out on cryostat sections taken from CNS preparations of adult specimens of the terrestrial snail, Helix pomatia, and the aquatic species, Lymnaea stagnalis, in order to visualize mild (carboxyl) and strong (sulphate) acidic groups, which are characteristic for different glucosaminoglycans. According to our findings, sulphated proteoglycans were abundant in the periganglionic sheath of both species, and they also occurred in the neuropil of Helix, whereas they were absent in Lymnaea. The interperikaryonal space contained mainly carboxyl residues, which might refer to the presence of hyaluronic acid. It is concluded that the ECM of the snail CNS, similarly to that in vertebrates, is partly composed of polymer macromolecules of different chemical properties. It is suggested that adaptation to environmental conditions and/or altered neuronal plasticity are responsible for the differences found in chemical characters of the ECM molecules between the two snail species.]

[Fingolimod therapy in multiple sclerosis - the issue of the pathomechanism]

TAR Lilla, VÉCSEI László

[Multiple sclerosis is an autoimmune inflammatory disease of the central nervous system with neurodegenerative chararacteristics. The newly discovered per os administrable drug fingolimod (FTY720) has a different mechanism of action than the current disease-modifying therapies. In vivo the drug binds to four out of the five sphingosine-1-phosphate receptors after phosphorylation. Fingolimod-phosphate (FTY720-P) causes internalization and degradation of the sphingosine-1-phosphate receptors in the membrane of lymphocytes thus in contrast to sphingosine-1-phosphate it acts like a functional antagonist. In experimental autoimmune encephalomyelitis - an animal model of multiple sclerosis - fingolimod blocks the sphingosine-1-phosphate gradient controlled lymphocyte egress from the lymph nodes and therefore reduces the peripheral lymphocyte count especially the encephalitogenic Th17 subset is reduced. Modulation of the sinus lining and blood-brainbarrier constructing endothelial cells also contributes to the complex mechanism of action. Additionally due to its liphohilic nature fingolimod is able to penetrate the blood brain barrier thus, beside its peripheral effects the drug can probably modulate the cells of the central nervous system directly. Presumably it can reduce neurodegeneration caused by astrogliosis through modification of astrocyte and oligodendrocyte activity. The results of current clinical studies are holding out with bright prospective in the aspect of either the favourable effects or the well tolerated side effects.]

[PLEIOTROPIC FUNCTIONS OF ERYTHROPOIETIN]

NAGY Judit, KISS István

[Erythropoietin produced by the foetal liver and the adult kidney is the major stimulator of erythropoiesis. Erythropoietin production is regulated by hypoxic activation of erythropoietin gene transcription. Recently, new sites of erythropoietin production have been found mainly in the central nervous system and in the cardiovascular system. These tissues have a paracrine and/or autocrine system of erythopoietin. The pleiotropic function of erythropoietin in these systems is tissue and cell protection by several mechanisms including inhibition of apoptosis, attenuation of ischaemic or reperfusion injury, anti-inflammatory and antioxidative effects. Furthermore, it promotes vascular recovery and enhances neoangiogenesis. In vivo and in vitro studies have proved that systemically administered human erythropoietin can also provide tissue protection. However, adverse effects of erythropoietin treatment such as hypertension, hyperviscosity and thrombosis may override the beneficial effect of systemic erythropoietin treatment. There are preliminary data that erythropoietin analogues, e.g., asyaloerythropoietin or carbamylated erythropoietin can provide tissue protection without stimulating erythropoiesis.]

[Central nervous system hemorrhage in Wegener’s granulomatosis]

SZABOLCSI Orsolya, SZÁNTÓ Antónia, ZEHER Margit

[In our case a 41-year-old man with following symptoms: non-productive coughing, fever, difficulty in breathing and weight loss was examined in February 2007, and on the basis of chest X-ray, CT and bronchoscopy, the possibility of neoplasm or tuberculosis cropped up. After the applied therapy (steroid, antibiotics, tuberculostatic drugs) the symptoms became more severe, i.e. hematuria and epistaxis were manifested. A tissue biopsy was carried out during bronchoscopy and the histological examination revealed granulomatous reaction. Meanwhile, the presence of c-ANCA was proved, and Wegener’s granulomatosis (WG) was diagnosed. In March 2007, sudden somnolence and left side hemiplegia developed, and a large haemorrhage was recognised on CT scan in the right fronto-temporal region, with regard to the haemorrhage, the patient had to undergo a neurosurgical operation. We started to treat him in April 2007 by intravenous steroid and 600 mg of cyclophosphamide (Cyc), and he regained the ability to walk again. In October 2007, the Cyc treatment was terminated, and we administered a maintenance therapy with methotrexat. During the regular medical check-up, a chest X-ray indicated a second attack in March 2008, which was confirmed by the chest CT, the clinical symptoms, increased anti-PR3 levels and c-ANCA positivity as well. The flair of the disease was established. Consequently, in April 2008 we decided on plasmapheresis therapy synchronised with Cyc. After that, we started an azathioprine maintenance therapy and he got rid of all the activation symptoms. We can say that with the adequate therapy started in good time and with the regular medical check up of the patient a good result can be achieved. It is true even in the case of WG disease associated by severe complication, for example central nervous hemorrhage.]

[EFFECTS OF KETAMINE ON THE DEVELOPING CENTRAL NERVOUS SYSTEM]

VUTSKITS László, GASCON Eduardo, KISS Zoltán József

[Ketamine is a widely used drug in pediatric anesthesia practice, acting primarily through the blockade of the Nmethyl- D-aspartate (NMDA) type of glutamate receptors. A growing body of laboratory evidence, accumulated during the past few years, suggests that this drug could have potential adverse effects on the developing central nervous system. The goal of this short review is to give a brief synopsis of experimental work indicating ketamine-induced developmental neurotoxicity as well as to discuss potential limitations concerning extrapolation of these studies to clinical practice.]
