The objective of this study was to examine the relationship between verbal memory and total cholesterol (TC) levels related to body mass index (BMI) in healthy young women. Verbal memory was assessed using the Rey Auditory-Verbal Learning Test (RAVLT) while total serum cholesterol was measured by enzymatic colorimetric test. In order to analyze the potential significance of BMI subjects were divided into three groups according to their calculated BMI percentile values. No significant correlation was found when assessing the group as a whole. However a remarkable pattern of correlation emerged when assessing the BMI groups separately: a close-to-significant positive correlation was found for total learning score and TC in the low BMI group, no correlation emerged in the medium BMI group while a strong inverse correlation was found in the high BMI group. These findings indicate that the relationship between verbal memory and serum TC level is also influenced by BMI.

[Selective dorsal rhizotomy in the treatment of spasticity - Hungarian experiences ]

FEKETE Gábor, NOVÁK László, VEKERDY-NAGY Zsuzsanna, BOGNÁR László

[Objective - We summarize our initial experiences with selective dorsal rhizotomy that we introduced in Hungary to manage the spasticity of patients with cerebral palsy. Patients and methods - Thirty spastic patients were enrolled in our study. All of the patients were operated between July 2014 and June 2015. We performed selective dorsal rhizotomy from a single-level approach at the level of conus medullaris in all cases, with electrophysiological control. Results - We could perform the surgery in all cases safely. Adverse events related either to damage of neurological structures, or to surgery did not occur. The planned rehabilitation courses before and after the operations are in progress in all cases. Conclusion - Selective dorsal rhizotomy is an irreversible surgical intervention to treat spasticity. With sufficient experience and electrophysiological control it can be performed safely, and the early results are promising. ]

[Experiences of hypothalamic hamartoma surgeries]

NOVÁK László, KISS Máté Tamás, KLEKNER Álmos, NAGY Andrea, FEDORCSÁK Imre, BOGNÁR László

[Background and purpose - Hypothalamic hamartomas are focal, benign congenital malformations that frequently associated with gelastic seizures. Behavioural disturbances, cognitive decline and the appearance of precocious puberty can also be observed. The most effective way to relieve the symptoms is the surgical disconnection between the hamartoma and the hypothalamus. In our study, we retrospectively analyzed the surgical indications and effectiveness of each approach. Methods - Between 1996 and 2014 we operated on 10 hypothalamic hamartomas. Endoscopic assisted resection was performed in three patients. Six patients underwent direct microsurgical resection in various approaches and one patient was treated with Gamma Knife. Results - We achieved significant decrease in the number of seizures in every patient presenting with various seizure types. The surgical resection was effective in the arresting of the puberty praecox as well. However the surgery of these lesions at their special location holds the danger of the appearance of new endocrinological symptoms. According to our observations the operation on hamartoma less effectively ameliorates the psychiatric symptoms than the others. Conclusion - The surgical treatment is effective in the reduction of the initial symptoms and we had no mortality. According to our analysis therapeutic success is anticipated but we couldn’t archive total symptomatic relief in every case. The first approach to these lesions should be the surgery which type must be tailored to each patient.]

Paraoxonáz-1-aktivitás és fenotípusos megjelenése sclerosis multiplexben

KURTULUS Fatma, YAMAN Aylin, ELLIDAG Yasar Hamit, EREN Esin, GÖMCELI Bicer Yasemin, YILMAZ Necat

Introduction - Human serum paraoxonase (PON1) and arylesterase (ARE) are lipophilic antioxidant enzymes. PON-1 serum activity diverges in individuals and populations, which might be due to polymorphisms in the PON-1 gene. The PON1 activity phenotyping method, based on the ratio of the stimulated PON activity and the ARE activity, could determine the low-activity homozygotes (QQ), intermediate activity heterozygotes (QR), and high-activity homozygotes (RR) regardless of the genotype. The aim of the present study was to determine the PON1 phenotype distribution and enzymatic activity of PON1 and ARE in multiple sclerosis (MS) patients. Materials and methods - Thirty-four relapsing remitting MS (RRMS) patients (22 females and 12 males; median age 42 (range 20-55) years) in the remission phase and thirty-four age-sex matched healthy controls (19 females and 15 males; median age 37 (21-60) years) were included in this study. All patients had clinically definite MS according to McDonald’s criteria. Results - Serum PON1 and ARE enzyme activities, as well as salt-stimulated PON1, were not significantly different between the patient and control groups. Phenotype distributions were as follows: QQ 58.8%, QR 38.2%, and RR 3% in MS patients (n=34); QQ 44.1%, QR 50%, and RR 5.9% in the control group (n=34). QQ (low activity) phenotypic distribution was more common in MS patients than controls, but this difference was not significant (p=0.14). Conclusions - Our results did not reveal meaningful relationships between PON1 activity or PON1 phenotypes and MS. More studies in larger samples and in all phases of the disease are needed in the future.

[New opportunities in neuro-rehabilitation: Robot mediated therapy in conditons post central nervous system impairments]

FAZEKAS Gábor, TAVASZI Ibolya, TÓTH András

[Decreasing the often-seen multiple disabilities as a consequence of central nervous system impairments requires broadening of the tools of rehabilitation. A promising opportunity for this purpose is the application of physiotherapy robots. The development of such devices goes back a quarter of century. Nowadays several robots are commercially available both for supporting upper and lower limb therapy. The aim is never to replace the therapists, but rather to support and supplement their work. It is worthwhile applying these devices for goal-oriented exercises in high repetition, which one physically fatiguing for the therapist or for the correction of functional movement by various strategies. Robot mediated therapy is also useful for motivation of the patient and making the rehabilitation programme more versatile. Robots can be used for assessment of the neuromotor status as well. Several clinical studies have been executed in this field, all over the world. Meta-analyses based on randomized, controlled trials show that supplementing the traditional physiotherapy with a robot-mediated component presents advantage for the patients. Further studies are necessary to clarify which modality and intensity of the exercises, in which group of patients, in which stage lead to the expected outcome.]

[Genetically determined diseases associated with pathological brain iron accumulation and neurodegeneration]

ÁCS Péter, MOLNÁR Mária Judit, KLIVÉNYI Péter, KÁLMÁN Bernadette

[The rare, genetically determined group of diseases characterized by pathological accumulation of iron in the central nervous system and progressive, typically movement disorder’s symptoms are called NBIA (neurodegeneration with brain iron accumulation). By the rapid development of molecular genetics, it has become apparent that different mutations in numerous genes can lead to pathological cerebral iron accumulation. Simultaneously, it has also been recognized that the age of onset, the symptoms and the prognosis of NBIA disorders are much more diverse than it was previously perceived. To our knowledge, a review article on the most recent clinical data of NBIA has not been published in Hungarian. In the first part of this publication, we survey the general clinical characteristics and the diagnostic algorithm of NBIA diseases and address some considerations for differential diagnostics. In the second part of this review, the particular NBIA disorders are presented in details. The purpose of this article is to provide a clinical overview that may be useful for neurologists, pediatricians and any other medical practitioners interested in this field.]

[Bone metabolism and body mass index in postmenopausal women]

TÁRCZY Csaba, TOLDY Erzsébet, SZERB János, VARGA László

[INTRODUCTION - In addition to several other causes constitutional factors play an important role in the development of osteoporosis.Various aspects of bone metabolism were examined to explain the differences in bone density between women with low and high body mass index (BMI). PATIENTS AND METHOD - One hundred and ninetytwo postmenopausal women were included in the study. Bone density was measured by forearm densitometry.To assess bone formation, serum osteocalcin levels were measured, while the rate of bone absorption was estimated from C-terminal telopeptide levels of collagen type I measured in urine and blood. RESULTS - The prevalence of osteoporosis was higher in women with low BMI than in those with normal or higher BMI. Bone metabolism - both formation and absorption - was increased in both groups, however, in women with low BMI this increase was more pronounced and bone metabolism tended to be shifted to absorption compared to patients with normal or higher BMI. CONCLUSION - Postmenopausal lean women have accelerated bone metabolism compared to obese women. This fact and the shift to absorption may be the main reasons for the higher frequency of osteoporosis found by densitometry in women with low BMI than in those with higher BMI.]

[Contact between the polycystic ovary syndrome and the metabolic syndrome]

KISS Katalin, VÁRADYNÉ HORVÁTH Ágnes, PAKAI Annamária

[Aim of the study: The objective of my thesis was to examine the presence of metabolic syndrome with the disorder of glucose metabolism among patients diagnosed with polycystic ovary syndrome (PCOS). Sample and methods: 98 female patients diagnosed with PCOS, aged 18-45, took part in the retrospective quantitative study, anthropometric data and laboratory parameters relevant to metabolic profile were analysed. We applied descriptive statistics with SPSS 17 software, as well as Chi2-test and regression analysis (p <0.05) Results: 46% of the study population were found to be overweight. There was a significant correlation between BMI index and blood pressure and lipid profile (p<0.05). Metabolic syndrome was confirmed by more than 40% of the patients Conclusion: The PCOS is an endocrine disease, which affects multiple organ systems. The patients should be screened towards metabolic syndrome to achieve a correct diagnosis, regardless of the BMI values. The findings of our research and the confirmed correlations highlight the need for a development in care protocols.]

[Survey on the dietary habits of children between the age of 4-10]

KISS-TÓTH Bernadett, BÍRÓ Lajos

[INTRODUCTION - The prevalence of overweightness and obesity among children is increasing in Hungary, while the inadequate or excessive intake of some nutrients is also representative. Keeping these inappropriate lifestyle habits in adulthood could significantly worsen the health status of the rising generation. METHOD - The sample is representative for the 4-10 year old children of Budapest and Kecskemét city. The dietary assessment was executed, using the internationally accepted 3 day dietary record method. Body mass index was also calculated from the measured body weight and height, creating BMI categories according to the Cole methodology. RESULTS - The ratio of overweightness and obesity resulted in 21% (19% for the 4-6 year old, 24% for the 7-10 year old), while 13% of them belonged to the underweight category. The nutritional problems, identified by adults, like the excessive fat intake, its inappropriate composition, the high sodium-, low calcium- and vitamin D intake already appears in the early stages of life. CONCLUSION - The results prove, that the education for healthy nutrition among children is in high priority, in which all stakeholders, like the parents, the governmental and non-governmental organisations, the educational institutes as well as the food industry plays an important role. ]
