Clinical Neuroscience - 2013;66(09-10)

[The world-wide incidence of vitamin D deficiency is high, independently of age. Multiple sclerosis is a chronic disorder, occuring in those who possess or are exposed to a combination of genetic and environmental risk factors. One of the environmental factors associated with the development is vitamin D. Vitamin D is an immunomodulatory agent, its role is verified in many of autoimmune diseases. Vitamin D inhibits IL-6, IL-17 and IL-23 secretions which are crucial in Th1 and Th17 differentiation and also decreases proinflammatorical cytokine production. Moreover it enhances the immunosuppressive IL-10 cytokine secretion and inhibits the T-reg cell development. These cytokines and cells are essential for the pathomechanism of multiple sclerosis. Data have shown, that the vitamin D levels above 100 nmol/l (40 ng/ml) is essential for the prevention of multiple sclerosis. Below this level the vitamin D supplementation is reasonable. In pregnancy, the vitamin D deficiency at the last two semester increases the risk for the multiple sclerosis of the infant. The optimal vitamin D level for multiple sclerosis patients is 100-150 nmol/l (40-60 ng/ml). There is no consensus for the role of vitamin D in multiple sclerosis yet, but until the achieving this, the diagnosis and the treatment of the vitamin D deficiency is crucial for scelrosis multiplex patients and in cases of elevated risk. Data shows, that in patient with multiple sclerosis the normal vitamin D level is suboptimal, however the exact role of vitamin D and doses must be clarified by interventional studies.]

[Occurence and molecular pathology of low grade gliomas]


[Background - The WHO grade I. and II. low-grade gliomas represent nearly the 15% of all primary brain tumors. These tumours contain clinically, hisologically and molecularly distinct tumor types. According to their histologic characteristic, grade II glial tumours are the diffuse astrocytoma, oligodendroglioma and oligoastrocytoma subgroups; the ependymal tumors are not included in this study. Methods - In our publication, we analysed the histological diagnosed glioma cases between 2007 and 2011 at our institution. Results - Low-grade gliomas were diagnosed in 127 cases (62 male / 65 female), and the mean ages were 39 years (±20.3). More than half of the cancers were localizated in the frontal lobe, and the second most frequent area was the temporal lobe. Finally, we comlete our report with an overview of major molecular pathways in low-grade gliomas.]

[Occurence and molecular pathology of high grade gliomas]


[Background - Glial tumours represent the most frequent type of primary brain cancers. Gliomas are characterized by heterogeneity that makes the diagnosis, histological classification and the choosing of correct therapy more difficult. Despite the advances in developing therapeutic strategies patients with malignant gliomas have a poor prognosis; therefore glial tumours represent one of the most important areas of cancer research. There are no detailed data on the epidemiology of gliomas in Hungary. Methods - In the first section of our publication, we analysed the histological diagnosed cases between 2007 and 2011 at the Institute of Pathology, University of Debrecen Medical and Health Science Centre. We analyzed the incidence of 214 high-grade gliomas by tumor grades, gender, age, and the anatomical localization. Results - The majority of cases were glioblastoma (182 cases), and the remaining 32 cases were anaplastic gliomas. The mean age of patients was 57 years (±16.4), and the male:female ratio was 1.1:1. The most frequent area of tumors was the frontal lobe followed by the temporal, parietal and occipital lobe. We include new findings published recently about glioma patogenesis, molecular pathways, mutant genes and chromosomal regions. We explain briefly the role of selected important genes in glioma genesis and give an update on knowledge provided by modern molecular methods, which could beneficially influence future therapy and the diagnosis of gliomas.]

[Infection-surveillance experience at a neurological intensive care unit]


[Infection-surveillance is an important part of the infection control system serving the protection of patients and healthcare workers as well. The continuous surveillance of health care associated infections is among the most important fields of patient safety and quality management. The aim of this study was to evaluate the frequency of the health care associated infections among patients at the neurointensive care unit. Moreover, we aimed to identify specific infectionforms and the most frequently occurring pathogens. We performed the study for a half-year according to the HELICSmethod proposed by the National Center of Epidemiology. In this setup we evaluated the infections and risk factors for infection (instrument-use, antibiotic therapy etc.) among the patients who spent at least 48 hours in the neurointensive care unit. During the six-month period, we observed 16 health care associated mono- and polymicrobial infections out of the 88 cases. Mainly Gram-positive pathogens were identified, but we found multidrug-resistant pathogens as well. Clinically diagnosed pneumonia was the most frequent among the infections. These infections were detected by a relatively low microbiological testing rate, which warns to increase sampling frequency to ensure more accurate data on infections. Infection control based on a comparative standardized infection dataset seems to be one of the most important preventive measures.]

[Split laminotomy and complementary spacer insertion for opening and enlargement of the thoracic spinal canal at infiltrative intramedullary tumor removal]


[Objective - The author main objective was to improve the previously developed technique of split laminotomy and moderate enlargement of the spinal canal with preservation of the majority of posterior structures, and to avoid the complications of the classic autologous bone grafting procedure. Methods - A multilevel spinous process splitting and distracting laminotomy technique with complementary spacer insertion between the laminar parts was developed. We used Poly-Ether-Ether-Ketone (PEEK) cages. This improved method was used in five patients to remove malignant intramedullary tumors at the thoracic level. Results - Adequate surgery of the tumors located intramedullary, and permanent decompression of the spinal canal was achieved in all patients using our new modified procedure. The results have been postoperatively confirmed with MRI and CT. The affected spine was the thoracic in all cases. The numbers of split laminae were three to five. Histological results were as follows: four intramedullary astrocytomas, one ependymoma. The ependymoma was completely, while the astrocytomas were only subtotally removed. In all cases heterologous grafts were inserted between the sides of the distracted laminas, to achieve the enlargement of the spinal canal. The mean duration of the whole surgical procedure was 118 minutes (range 91 to 145 minutes). The average follow-up was 11.2 months, with the range from five to 16 months. Upon postoperative neurological follow-up, no complications were revealed related to the newly developed procedure. The postoperative followup CT scans demonstrated bony healing, with a cage between the osteotomized faces. No compression or dislocation of the spacer was seen. Instability was not detected in any of the patients by flexion or extension lateral radiographs. Conclusion - This modification of the split laminotomy and heterologous grafting method fulfills the requirements of other laminotomy techniques. The split laminotomy is suitable for removing intramedullary tumors, and the posterior stabilizing structures of the spine, as the vertebral laminae and the longitudinal musculature are completely prevented. Due to use of allograft the complications of the classic hip bone grafting procedures are avoided. The spacers, inserted between the osteotomized faces, provided permanent decompression of the spinal canal, and bony healing - throughout the spacer - of the splitted vertebral laminae, without iliac graft complications.]

Matrix metalloproteinases and their tissue inhibitors in relapsing remitting multiple sclerosis: Possible markers and treatment agents


Matrix metalloproteinases (MMPs), which are synthesized by many cell groups and responsible for the destruction of matrix proteins, and endogen tissue inhibitors of MMPs (TIMPs) have a role in the pathogenesis of Multiple Sclerosis (MS) by affecting the blood-brain barrier. We aimed to investigate the role of MMPs and TIMPs in the immunopathogenesis and in the course of multiple sclerosis (MS). We enrolled 25 relapsing remitting MS patients, who had a definite MS diagnosis according to McDonald criteria and 25 healthy subjects similar for age and gender as control group. MMP-9- and TIMP-1 levels were measured twice in patient group (one time during an attack and one in remission) and once in healthy subjects. MMP-9- and TIMP-levels of patients during attack and remission period and MMP-9/TIMP-1 ratio were found significantly higher than in the control subjects. In patient group MMP-9 and TIMP-1 levels and MMP-9/TIMP-1 ratio during attacks were not significantly different than during remission period. However, when subdivided according to their number of attacks, patients with 2 attacks had significantly higher levels during attack period comparing to remission period (p<0.05); in case of patients with more than 2 attacks did not have a statistically significant difference in attack and remission periods. Matrix metalloproteinases are important actors in MS immunopathogenesis, particularly in the early period and inhibitor agents for these enzymes can be used as a treatment option.

[Family planning in multiple sclerosis: conception, pregnancy, breastfeeding]

RÓZSA Csilla

[Family planning is an exceptionally important question in multiple sclerosis, as women of childbearing age are the ones most often affected. Although it is proven that pregnancy does not worsen the long-term prognosis of relapsing-remitting multiple sclerosis, many patients are still doubtful about having children. This question is further complicated by the fact that patients – and often even doctors – are not sufficiently informed about how the ever-increasing number of available disease-modifying treatments affect pregnancies. Breastfeeding is an even less clear topic. Patients usually look to their neurologists first for answers concerning these matters. It falls to the neurologist to rationally evaluate the risks and benefits of contraception, pregnancy, assisted reproduction, childbirth, breastfeeding and disease modifying treatments, to inform patients about these, and then together come to a decision about the best possible therapeutic approach, taking the patients’ individual family plans into consideration. Here we present a review of relevant literature adhering to international guidelines on the topics of conception, pregnancy and breastfeeding, with a special focus on the applicability of approved disease modifying treatments during pregnancy and breastfeeding. The goal of this article is to provide clinicians involved in the care of MS patients with up-to-date information that they can utilize in their day-to-day clinical practice. ]

[The role of anaerobic bacteria in brain abscesses: a literature review]


[Brain abscesses are potentially serious, life-threatening diseases that pose a complex diagnostic challenge not only to neurosurgeons but also to clinical microbiologists, neurologists, psychiatrists, infectologists. The etiology of brain abscess is usually polymicrobial, most commonly involving a variety of aerobic and obligate anaerobic bacteria. Epidemiological studies on the anaerobic etiology of brain abscesses are common between the time period of 1960s and 1980s, but today there are very few new publications on the subject. The role of anaerobic bacteria in this disease was presumably underdiagnosed for a very long time, as many laboratories did not have the adequate laboratory capabilities for their cultivation and identification. The purpose of this review is to summarize the available literature on the etiology of obligate anaerobic bacteria in brain abscesses, including their prevalence and current therapeutic recommendations.]

[Monitoring of the blood pressure lowering effectiveness of ramipril-amlodipine fix combination – a non-interventional trial (RAMONA study)]


[Purpose: Monitoring the effectiveness and safety of the fix combination formulation Egiramlon® therapy containing ramipril and amlodipin in patients, suffering from mild or moderate hypertension despite antihypertensive treatment. Patients and methods: Open, prospective, phase IV clinical observational study, which involved 9169 patients (age >18) with mild or moderate hypertension [TUKEB No: 16927- 1/2012/EKU (294/PI/12.)]. Ramipril/Amlodipin 5/5, 5/10, 10/5, 10/10 mg combinations were administered/ titrated in three visits, during the four months period according to the physician’s decision Blood pressure was measured by validated blood pressure sphygmomanometry and ABPM (Meditech, Hungary). The dosis of the fix combination formulation was determined individually during the visits by the 923 doctors involved in the study. The target blood pressure value was 140/90 mmHg, but in case of high risk patients population (diagnosed cardiovascular disease, diabetes), 130/90 mmHg target value was determined. Results: In 70.1% of the patients had no protocoll deviation. Patients data and examination results were processed according to this 6423 patient population. The average age of the patients were 60.2 year, in 50-50% sex distribution. The average duration of the treated hypertension was 9.8 years and the average blood pressure value was 157/91 mmHg. Till the end of the study, systolic blood pressure has decreased with 26.4 mmHg and diastolic pressure with 11.8 mmHg. An average 5.5 bpm heart rate frequency decreasing was observed at the end of the study. As a result of the treatment 52.4% of the patient population has reached the target blood pressure value.]

PÉNTEK Márta, GULÁCSI László, RÓZSA Csilla, SIMÓ Magdolna, ILJICSOV Anna, KOMOLY Sámuel, BRODSZKY Valentin

[Background and purpose - Data on disease burden of multiple sclerosis from Eastern-Central Europe are very limited. Our aim was to explore the quality of life, resource utilisation and costs of ambulating patients with multiple sclerosis in Hungary. Methods - Cross-sectional questionnaire survey was performed in two outpatient neurology centres in 2009. Clinical history, health care utilisation in the past 12 months were surveyed, the Expanded Disability Status Scale and the EQ-5D questionnaires were applied. Cost calculation was conducted from the societal perspective. Results - Sixty-eight patients (female 70.6%) aged 38.0 (SD 9.1) with disease duration of 7.8 (SD 6.7) years were involved. Fifty-five (80.9%) had relapsing-remitting form and 52 (76.5%) were taking immunomodulatory drug. The average scores were: Expanded Disability Status Scale 1.9 (SD 1.7), EQ-5D 0.67 (SD 0.28). Mean total cost amounted to 10 902 Euros/patient/year (direct medical 67%, direct nonmedical 13%, indirect costs 20%). Drugs, disability pension and informal care were the highest cost items. Costs of mild (Expanded Disability Status Scale 0-3.5) and moderate (Expanded Disability Status Scale 4.0-6.5) disease were 9 218 and 17 634 Euros/patient/year respectively (p<0.01), that is lower than results from Western European countries. Conclusion - Our study provides current inputs for policy making and contributes to understanding variation of costof- illness of multiple sclerosis in Europe.]
