NAGY Csaba, BAJZIK Gábor, SKOBRÁK Andrea, CSORBA Eszter, LAJTAI Anikó, BALOGH Gábor, NAGY Ferenc, VAJDA Zsolt

[Hemiplegic migraine is a rare subtype of migraine that is associated with reversible motor weakness in the aura phase. This is an uncommon form of migraine usually starting in childhood. The purpose of this case report is to highlight the differential diagnostic difficulty of the first attack. We describe a case, where the fluctuating unilateral motor weakness and aphasia suggested that the patient had ischaemic stroke. Nevertheless the brain MRI and MR angiography, the measured 5-hydroxyindole acetic acid (5-HIAA) concentration changes and the spontaneously improving clinical status proved the diagnosis of hemiplegic migraine. The MRI and MR angiography was very beneficial in establishing the correct diagnosis in this case. To distinguish between the familiar and sporadic type of hemiplegic migraine further genetic tests can be carried out.]

[Non-contrast brain ct based systemic thrombolysis of two wake up ischemic stroke patients in rural settings]

POZSEGOVITS Krisztián, RENCZ László, CSÚSZ Lajos, SZABÓ Géza

[Background and presentation - Conventionally the acute ischemic stroke patients who wake up with symptomes (WUS - wake up stroke) cannot benefit from systemic thrombolysis due to the uncertainty of the exact onset time of the cerebrovascular event. Perfusion brain imaging could be used as patient selection tool but the method is not available in many settings. Simple non-contrast CT scan is easily accessible and reliable as it shows the different stages of the evolving ischemia with high accuracy. Early brain CT scan results of WUS patients have the same characteristics as the ones who are surely within therapeutic window. The intravenous thrombolysis with recombinant tissue plasminogen activator (rTPA) of WUS patients seems to be similarly successful as the ones with known onset time, the treatment does not come with excess complications, higher rate of symptomatic intracranial hemorrhage was not found in previous reports. Purpose - In this report we present two systemic thrombolysis cases of acute ischemic stroke patients who woke up with stroke symptoms. Methods - In 2014 and 2015 we performed systemic thrombolysis for one wake up stroke patients, respectively. Both patients had large vessel occlusion. Indication was based on favourable non-contrast brain CT scan results. Results - Treatment of these two patients with rTPA proved to be safe, no hemorrhage occurred after treatment. Conclusion - We presented two acute ischemic stroke patients with symptomes at early wake up who were treated intravenously with recombinant tissue plasminogen activator based on non-contrast CT alone without complications and some moderate improvement at 90 days in the settings of a rural town hospital in a middle income country.]

Independent validation of the Quality of Life in Essential Tremor Questionnaire (QUEST)

KOVÁCS Márton, MAKKOS Attila, JANSZKY József, KOVÁCS Norbert

Quality of Life in Essential Tremor Questionnaire (QUEST) was specially developed for essential tremor population to measure the health-related quality of life. Besides the development of the Hungarian version, we performed an independent testing of the scale adding further information on its clinimetric properties. In this study 133 ET patients treated at University of Pécs, Hungary, were enrolled. Besides QUEST, we assessed Patient’s Global Impression-Severity (PGI-S) and Fahn-Tolosa-Marin Tremor Rating Scales. After the independent validation in accordance to the Classic Theory of Tests, we evaluated cut-off values for detecting clinically meaningful ET-related disabilities based on receiver operating characteristics analysis. Cronbach’s a was 0.897. QUEST demonstrated high convergent validity with PGI and divergent validity with disease-duration, positive family history, need for deep brain stimulation surgery, and the presence of depression and anxiety. Presence of moderate ET-related disabilities was identified by scores > 11.25 points on QUEST-SI (sensitivity: 77.4%, specificity: 83.3%); whereas scores > 20.35 points indicated severe ET-related disabilities (sensitivity: 83.3%, specificity: 59.1%). We demonstrated that the fundamental clinimetric properties of the QUEST are satisfactory.

[Angiogenesis – antiangiogenesis]

PAKU Sándor, SEBESTYÉN Anna, KOPPER László

[Tumor growth requires vascularization to be supplied by oxygen and nutritients. The vascular network could be different between tumors, even during the development of the same tumor (local and systemic spreading), from the occupation of already present vessels to the real angiogenesis (i.e, proliferation of endothelial cells). Moreover, the tumor cells can create channels, mimicking the normal vessels. This spectrum in morphology should be refl ected in the therapeutic response, in the effectiveness of antiangiogens, but the how is unknown. It is sure that acceptable clinical activity can be achieved only with combinations, both with traditional cytotoxic and targeting drugs. The clinical advantage can be hampered by increased toxicity, demanding supportive actions. One of the key decisions is to select the proper therapy considering the patient and the tumor characteristics (today increasingly at molecular level) and predict the response to the therapy. Such (bio)markers are still missing, although intensive research trying the best. Since the main target of antiangiogenic drugs (today and tomorrow) the VEGF/R family, a useful marker is expected from them. The inhibition of angiogenesis is a logical step against the solid tumors and these steps slowly but steadily can improve the patients life-time, as well as their quality of life.]

[The role of the family physician in the preparation for liver transplantation in Wilson’s disease]

FARKAS Anett, KALABAY László, MÁTHÉ Zoltán, MÁRKUS Bernadett, SZALAY Ferenc, VÖRÖS Krisztián, TORZSA Péter

[Wilson’s disease is an autosomal recessive disease with toxic copper accumulation caused by the mutation of the ATP7B gene in chromosome 13. The estimated prevalence of the disease is 2-3 / 100000. Early diagnosis is important because the treatment may stop the progression and could result regression or it can prevent the clinical manifestation of the disease. In our case study we describe how difficult could be to diagnose the disease, the role of the family physician in the preparation for liver transplantation and in the follow-up care. This case is an example demonstrating that Wilson's disease is often diagnosed only years after the appearance of the first symptom. We review the most important literature data on Wilson’s disease. ]

How to minimize the risk for headache? A lumbar puncture practice questionnaire study

JONATAN Salzer, RAJDA Cecilia, SUNDSTRÖM Peter, MATTIAS Vågberg, VÉCSEI László, ANDERS Svenningsson

Background - To lower the risk for post lumbar puncture (LP) headache the American Academy of Neurology (AAN) recommended using small bore atraumatic needles together with stylet reinsertion in a report from 2005. It is unclear whether these recommendations are followed or not. Objectives - To investigate the diagnostic LP preferences with respect to the AAN guidelines among neurologists by use of a short online questionnaire, and to review previously published literature on the subject. Results - A total of 284 respondents who performed diagnostic LPs completed the questionnaire. Almost half (41%) answered that they always use atraumatic needles. The most common reason (73%) for not using atraumatic needles was that these were not available. Less than half of the respondents who performed LPs had knowledge about the AAN guidelines for diagnostic LPs, and 48-76% agreed with the different recommendations therein. Five previously (1998-2015) published studies investigating LP practice among neurologists were identified. The reported frequency of atraumatic needle use (always/routinely) varied between 2 and 16%. Discussion - Atraumatic needle use was more common in this study compared with previous publications. There is still skepticism regarding some of the AAN recommendations, and needle availability appears to be the most important factor preventing atraumatic needle use. To increase the use of atraumatic needles we may perform additional studies investigating their potential benefits, and arrange training sessions for neurologists to increase their awareness and level of comfort with the atraumatic LP technique.

[Associated factors of independency in older adults with cognitive impairment living in a long term care institute]

KOVÁCS Éva, JÓNÁSNÉ SZTRUHÁR Izabella, KARÓCZI Csilla Kata, VASS Zsolt, FARKAS Lilla

[Aim of the research: Functional independence determines the elderly’s health and quality of life. In them cross-sectional study the authors analysed the associations between functional abilities (balance, gait, functional mobility, cognitive abilities), age, BMI and comorbidities and independency in older adults with cognitive impairment. Research and sampling methods: 110 elderly people were measured. Self-sufficiency was measured by the Katz-index, balance, and gait by the Tinetti Test and functional mobility by the Timed Up and Go Test. Correlations between variables were analysed with the Spearman’s rank-order correlation. Results: There was strong association between balance (r=0,557), gait (r=0,515), functional mobility (r=-0,647), and independency. It means the better the balance, gait, and functional mobility is, the higher the independency is. There was weak association between age, BMI, cognitive abilities, comorbidities and independency. Conclusion: Results show that preserving of the functional independence in older adults with cognitive impairment is a multidisciplinary task: physiotherapists and nurses should work together to complete doctors’ curative work of chronic diseases.]

[“Yesterday no longer exists either…” - End-of-life ethical issues in the care of dementia patients]

HEGEDÛS Katalin

[The number of dementia patiens is rising. Most of them die in various institutions, often after many years of care. The long process of nursing and care entails particular ethical requirements that are built primarily on vulnerability, dignity, and dia-logue. The dialogue, however, is often absent from the care of dementia patients. Do we find - as physicians, patients, relatives - that specific time when the patients can still make decisions about end-of-life treatments in a good mental state? Most patients would like to participate in these decisions. Talking about these issues in the early stage of dementia may help in the great emotional burden of family members and caregivers. Therefore the ethical aim is the ad­vance care planning (ACP) of the end-of-life treatments. The study reviews the latest scientific results, with special regard to resources that may be helpful in the course of conversations between doctor and patient on end-of-life preferences, and in the preparation for decision making. ]

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.
