[Dissection of the cervical and intracranial vasculature is a rare but important cause of ischaemic stroke especially in young adults. In the majority of cases it affects the extracranial vessels, mostly the internal carotid artery. It might be categorized as spontaneous or traumatic, causing diverse clinical symptoms. Dissection might lead to ipsilateral stroke mainly by artery-to-artery embolisation. Due to its relative rarity compared to the classic ischaemic stroke of the elderly, there are much less clinically relevant information for the clinician to rely on. Several large, randomised, multicentered, prospective studies and some smaller, retrospective analyses have been published recently concerning the genetic background, epidemiology, acute care and secondary prevention of supraaortic arterial dissection which helps the neurologist to provide evidence-based care for his patient. Our aim is to give a short, up-to-date overview of arterial dissections with two case reports.]

[Eating disorders and pregnancy - a review of literature]

DUKAY-SZABÓ Szilvia, VARGA Márta, TÚRY Ferenc

[Eating disorders are psychosomatic disorders affecting primarily women, and influence reproductive functions as well. They have an impact on ovarial cyclem fertility, course of pregnancy, process of delivery, post partum period. Moreover, some data show that they can influence the adult health status. Extensive research from the last three decades call the attention to the fact that besides the classical eating disorders (anorexia nervosa and bulimia nervosa) the newer types (e.g., orthorexia nervosa), and subclinical disorders also occur in a subgroup of pregnant women. For this reason it is of key importance that the personnel working in the territory of obstetrics and gynecology have a solid knowledge about the symptoms, screening and therapeutical opportunities, and outcome of these disorders. The review summarizes the recent research data about the relationship of eating disorders and pregnancy.]

Stress-induced corticosterone rise maintain gastric mucosal integrity in rats

LUDMILA Filaretova, MARINA Myazina, TATIANA Bagaeva

Background - To investigate contribution of glucocorticoids to the maintenance of gastric mucosal integrity during stress we predominantly used ulcerogenic stress models. Using these models we demonstrated that glucocorticoids released in response to the ulcerogenic stimuli attenuated their harmful action on the gastric mucosa. Purpose - In the present study we hypothesized that mild stressors does not damage the gastric mucosa due to gastroprotective action of glucocorticoids released in response to these stressors. Methods - To verify the hypothesis the effects of normally non-ulcerogenic mild stimuli (15-30 min cold-restraint) on the gastric mucosal integrity have been studied under the circumstances of inhibition of the hypothalamic-pituitaryadrenocortical axis in rats. The hypothalamic-pituitary-adrenocortical axis was inhibited by: 1) fast inhibitory action of metyrapone, inhibitor glucocorticoid synthesis; 2) fast inhibitory action of NBI 27914, the selective antagonist of cortricotropin- releasing factor receptor type 1; 3) delayed inhibitory action of a single pharmacological dose of cortisol injected one week before the onset of stress stimulus. Results - Each of these pretreatments significantly decreased 15-30 min cold-restraint-produced corticosterone levels: 37.2±1 vs 22.5±1.2 (p<0.05) after metyrapone; 52.1±0.9 vs 41.4±1 (p<0.05) after NBI, and 64.2±4.2 vs 16.7±1.5 (p<0.05) after cortisol pretreatment. The inhibition of stress-induced corticosterone rise resulted in an ap - pearance of gastric lesions after the onset of these mild stressors in rats. Conclusions - The results suggest that in rats with inhibited stress-induced corticosterone rise normally non-ulcerogenic stimuli are transformed into ulcerogenic ones and confirm the hypothesis. The findings further support for the point of view that glucocorticoids released during acute stress are gastroprotective factors.

Adult attachment and parental bonding in irritable bowel syndrome and in panic disorder - Implications for psychotherapy

PÉNZES István, CZEGLÉDI Edit, SZALAI Dömötör Tamás, CSALA Irén, TÚRY Ferenc

Background and purpose - Attachment theory provides an integrative perspective about the interplay between cognitive, affective, behavioral and interpersonal processes and is relevant for understanding irritable bowel syndrome (IBS) and panic disorder (PD). The aim of the present study was to examine the adult attachment style and parental bonding of IBS and PD patients. Methods - In a cross-sectional questionnaire-based study, 65 PD and 65 IBS patients with clinical diagnosis participated. Measures were Attachment Style Questionnaire, Experiences in Close Relationships Scale - Revised, and Parental Bonding Instrument. Results - The frequencies of insecure attachment (80.0% vs. 63.1%) and paternal neglect (35.4% vs. 16.9%) were higher in IBS than in PD (χ2 (1)=4.571, p=0.033, and χ2 (3)=7.831, p=0.050, respectively). The frequency of secure attachment was significantly higher for optimal paternal bonding than with suboptimal paternal bonding (75.0% vs. 21.9%, χ2 (1)=19.408, p<0.001). According to the results of multiple binary logistic analysis, optimal paternal bonding predicted secure attachment after adjusting for the background variables (OR=9.26, p=0.001). Conclusion - A high frequency of insecure attachment was present in both groups, especially in IBS. With regard to maternal bonding, IBS and PD groups showed similar patterns, while an apparent difference was observed for paternal bonding. These highlighted the developmental similarities of these two, symptomatically different disorders. While optimal maternal bonding did not predict adult attachment security, paternal bonding did thus replete with therapeutic implications. Attachment functions, like responsiveness, attunement and affection modulation were apparent in the psychotherapist-patient relationship as well.

Cerebral vasomotor reactivity in fibromyalgia patients and its relationship to central neuropathic pain

GULER Sibel, KURTOGLU S. Hakan, KEHAYA Sezgin, PAMUK Nuri, CELIK Yahya

Background - Cerebral vasomotor reactivity, defined as the cerebral vasculature response to hypoxia, is not wellunderstood in fibromyalgia (FM) patients. This study investigated the difference in the cerebrovascular reactivity (i.e., responsiveness to hypercapnia was evaluated by use of breath- holding index) to the breath-holding index (BHI) between patients with fibromyalgia and a group of normal controls. Methods - The study included 40 FM patients and 40 healthy subjects. Cerebrovascular reactivity was evaluated using the BHI, which is a nonaggressive, well-tolerated, real-time, reproducible screening method to study cerebral haemodynamics. Insonation depth and basal velocity were symmetrical and not significantly different between the two groups (p>0.05). All patients completed the Revised Fibromyalgia Impact Questionnaire (FIQR), Hospital Anxiety and Depression Scale (HADS), visual analogue scale (VAS), and the somatization subscale of the SCL-90-R symptom checklist. Results - The BHI ranged from 0.30 to 2.20 (mean 1.11±0.45) in the FM patients and 1.10 to 2.80 (mean 1.90±0.35) in the control group (p<0.001). Disease duration and right BHIaverage and left BHIaverage values exhibited a significant negative correlation (r=-0.877; p<0.001, r=-0.842; p<0.001, respectively). As pain and fatigue scores increased, the right BHIaverage and left BHIaverage values decreased (r=-0.431; p=0.005, r=-0.544; p<0.001, r=-0.341; p=0.031, r=-0.644; p<0.001, respectively). Conclusions - BHI values showed that cerebrovascular reactivity in FM patients decreased in comparison to healthy individuals. BHI decreased as disease duration and severity increased. Cerebrovascular reactivity decreased in FM patients, and this phenomenon should be accepted as an abnormality. Additionally, this outcome may have been the result of a mechanism responsible for central neuropathic pain.

[Operation - rehabilitation - employment]

MÉSZÁROS Gabriella, FEHÉR Miklós, BORBÉLY Csaba

[In this article we would like to bring the attention to the importance of early rehabilitation, coordinated operation of different subdivisions of rehabilitation and the expanding opportunities after medical care through following a 38- year-old female patient's case who was operated 6 years ago with anaplasticus oligodendroglioma. We find it important that the experts working on the field of health care, social services or labour should be aware of the possibilities of rehabilitation of their patients from the capability assessment, through its development until their placement in integrated labour market. It is important, that even during the medical care both the client and their relatives receive proper information.]

Hyperhomocysteinemia in female migraineurs of childbearing ages


Background and purpose - Migraine is a risk factor for ischemic stroke in women of childbearing ages. Previous researches revealed a higher prevalence of hyperhomocysteinemia in migraineurs. Possible differences on the frequencies of hyperhomocysteinemia between migraine with aura and migraine without aura could contribute the established variances in stroke risk between these migraine types. Therefore, we aimed to search if the frequency of hyperhomocysteinemia was different between these subtypes of migraine or not. Methods - We analyzed the findings of serum homocysteine levels in female migraineurs of 16-49 years old who admitted to our outpatient clinic. Results - Homocysteine level was elevated in 13.3% of study population. There were not any significant differences on median serum homocysteine levels between migraine with aura (8.0 mikromol/L) and without aura (8.5 mikromol/L). (p=0.426) The frequencies of hyperhomocysteinemia were also similar (9.1% versus 16.7%, respectively; p=0.373). Correlation analyses did not reveal any linear correlation between ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura (p=0.417 and p=0.647, respectively). Similarly, any linear correlation between disease ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura was not detected (p=0.359 and p=0.849, respectively). Conclusion - The median serum homocysteine levels and the frequencies of hyperhomocysteinemia are similar between migraine with aura and without aura in women of childbearing ages. Therefore, the variances on stroke risk ratios between these types of migraine are probably not originated from the differences of serum homocysteine status.

[Background - In the industrialized countries the very elderly stroke patient is more frequent than before. For the time being Japanese people have the highest expected lifespan, so the epidemiological features of stroke in the very elderly can be examined here quite easily. From a few publications with low case number it is known that in this group of patients the statistical characteristics of stroke is remarkably different from the youngers' one. Subjects and methods - The subjects aged 85 or more years were selected from the Akita Stroke Registry with first-ever acute stroke from 1996 to 1998. Results - 8,046 cases were recorded. There were 7362 patients aged <85 years, and 684 patients aged ≥85 years (8.5%). Sex ratio (women/men) was 1.89 in the two age groups. In the population of Akita the crude incidence of firstever stroke was 222/100,000/year, and 1,085/100,000/year in the very elderly, who were characterized with relatively lower prevalence of stroke risk factors, except that of atrial fibrillation (26.9%) and cardiac diseases (34.2%). The stroke subtype distribution (cerebral infarction 73.2%, intracerebral haemorrhage 20.6%, subarachnoidal haemorrhage 6.1%) was significantly different from the one known in Japan. Mortality rates were considerably high, especially in the SAH group. The most powerful prognostic factor of death was the consciousness level at onset. The following in order of predicting value was the SAH stroke subtype. Conclusion - While people aged 85 years or more had relatively lower prevalence of cardiovascular risk factors, they suffered stroke with very high frequency, the evolved cerebrovascular event caused very severe symptoms and led to death with high rate. Implicitly this is illuminating the complexity of aging as a procession, furthermore it raises the importance of prevention, more rather of the acute stroke care and rehabilitation in this high age group.]

[Holistic approach to cardiovascular prevention]


[Cardiovascular diseases, primarily the organic manifestations of atherosclerosis, such as coronary artery disease, ischaemic stroke, and peripheral arterial diseases, represent the largest healthcare problem in the developed countries, since the mortality, disability, and need for hospitalisation caused by them constitute a bigger burden than that caused by all other diseases combined. A modern, holistic approach to cardiovascular prevention should consider the complete cardiovascular continuum, including genetic predisposition, social-economicalcultural background, environmental factors, the integrated effect of atherosclerotic risk factors, the inhibition of progression of functional and morphologic damages that have already developed, and, if possible, the promotion of regression. Besides targeting the individual, prevention at the public and social level is also important.]


[The impact of vitamin D in infertility and the role in pregnancy and in nursing period]


[Various medical associations issue different recommendations for the prevention and treatment of vitamin D deficiency. These significant differences are partly explained by the different definition of normal vitamin D level and the use of completely different mathematical models to predict the increase in vitamin D level as a response to therapy. According to the Institute of Medicine, the target vitamin D level is 20 ng/ml, whereas the Endocrine Society recommends 30 ng/m as the minimum target value. These differences show that the two Society have different views on the risk of adverse effects. Screening, however, is not recommended by either society. In this review I summarize the role of the vitamin D supplementation in the prevention of infertility. Also, I suggest the protective effect of the vitamin D during the pregnancy. In my opinion screening program against D hypovitaminosis should be performed in case of infertility and in pregnancy, because data show a protective role of vitamin D against many disease of newborn. ]

[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.]
