[The authors focus on the rehabilitation of patients with dysphagia caused by surgical and/or irradiative treatment of head and neck tumors as well as neurogenic diseases. The complex rehabilitation includes treatment of the oropharyngeal swallowing dysfunction as well as the therapy of communicative disabilities. The home care of patients with dysphagia, which can not only be life threatening, but also causes social isolation, is an important task for the general practitioner.]

[CLINICAL EXAMINATION OF ENZYME CATALASE AND ITS MUTATIONS IN HUNGARY]

GÓTH László

[Hydrogen peroxide is formed during physiological and pathological processes in the human body. Hydrogen peroxide in high concentration and its more reactive compound (hydroxyl radical) can damage cells. Recent findings show that hydrogen peroxide in low concentration is required for many physiological pathways of cell signaling such as diabetes, platelet activation, inflammation, immune response. In human tissues the steady state concentration of hydrogen peroxide changes between 0.1 nmol/l-100 micromol/l. The main regulator of hydrogen peroxide metabolism is the enzyme catalase. This enzyme has a fast and high activity on high hydrogen peroxide concentrations and it shows a weak effect on its physiologic concentration. Acatalasemia, the inherited deficiency of enzyme catalase seems to be rather a syndrome than a simple enzyme deficiency as it was thought earlier. It is associated with changes in lipid, carbohydrate and erythrocyte metabolisms. Contrary to the the worldwide (11 countries) distribution of acatalasemia only two syndrome causing catalase mutations have been reported from Japan. Recently, four novel catalase mutations detected in one acatalasemic and 12 hypocatalasemic Hungarian families which mutations are responsible for the decreased catalase activity.]

[THE VALUE OF EXHALED NITRIC OXIDE IN ASTHMA BRONCHIALE - DIFFERENTIAL DIAGNOSIS AND MANAGEMENT]

HORVÁTH Ildikó

[Although the differential diagnosis of asthma is simple in most cases, there are cases causing difficulties. Beside as an aid in diagnosis, there is a growing need for new tests to monitor airway inflammation to optimize and monitor the effect of treatment. Following the traditional methods used in everyday clinical practice a new method, the measurement of exhaled nitric oxide was introduced in the past decade. With this method, completely new information can be obtained about asthma supplementing other results in diagnosis making and disease monitoring. It is also expected to become the part of clinical practice in the next few years. The concentration of exhaled nitric oxide is elevated in asthmatic patients and its elevation is positively related to the degree of eosinophilic airway inflammation and symptoms. This measurement is approved in the European Union and in the USA for clinical use to monitor the effectiveness of anti-inflammatory treatment in asthma.]

[The connection between the socioeconomic status and stroke in Budapest]

VASTAGH Ildikó, SZŐCS Ildikó, OBERFRANK Ferenc, AJTAY András, BERECZKI Dániel

[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

[The Comprehensive Aphasia Test in Hungarian]

ZAKARIÁS Lilla, RÓZSA Sándor, LUKÁCS Ágnes

[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]

The applications of transcranial Doppler in ischemic stroke

FINNSDÓTTIR Herdis, SZEGEDI István, OLÁH László, CSIBA László

Background: This overview provides a summary of the applications of transcranial Doppler (TCD) in ischemic stroke. Results: A fast-track neurovascular ultrasound protocol has been developed for detecting occlusion or stenosis. The technique is more reliable in the carotid area than in the posterior circulation. By monitoring the pulsatility index the in­crea­sed intracranial pressure can be diagnosed. TIBI score was developed for grading residual flow. TCD has been shown to accurately predict complete or any recanalization. Regarding recanalization, TCD has a sensitivity of 92%, a specificity of 88%, a positive predictive value of 96%, a negative predictive value of 78% and an overall accuracy of 91%, respectively. Sonothrombolysis seemed to be a promising application but randomized controlled trials have shown that it does not improve clinical outcome. TCD examination can detect microembolic signals (MES) which are associated with an increased risk of stroke. Micro­em­boli were detected in symptomatic and asymptomatic carotid artery stenosis and during carotid endarterectomy. The number of microemboli can be decreased by antithrombotic therapy. Contrast en­chan­ced examination and Valsalva maneuver with continuous TCD monitoring can accurately screen for right-to-left shunt.

Hyperhomocysteinemia in female migraineurs of childbearing ages

ALEMDAR Murat, SELEKLER Macit Hamit

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.

[Results of intrathecal baclofen therapy on spasticity in patients with brain injury]

DÉNES Zoltán, KLAUBER András, BOTH Béla, ERÕSS Loránd

[Objectives - To evaluate the results of intrathecal baclofen (ITB) therapy on the spasticity in patients with brain injury. Method - Retrospective study in Brain Injury Rehabilitation Unit between January 2001 and December 2010. Results - During the last ten years, in our unit 13 patients were involved into ITB therapy on severe spasticity, after brain injury, while more than 100 Baclofen pumps were implantated in Hungary with Hungary with coordination of the Multidisciplinary Team. ITB therapy was indicated in severe spasticity developed after seven cases of traumatic brain injuries, five cases of strokes and one case of anoxic brain injury. The mean age of patients was 26 years (18- 52). At the time of pump implantation three patients were in vegetative state. The shortest period elapsed between the brain injury and pump implantation was three months and the longest period was nine years, mean 15 months. Baclofen pump had to be changed in six cases after six years, and was removed in three cases due to decreasing spasticity. Catheter revision was performed in two cases due to flow problem. We had no complication in association with ITB therapy. Conclusions - Intrathecal baclofen therapy seems to be an effective and safe treatment in patients with severe spasticity of cerebral origin. We suggest team (neurosurgeon and rehabilitation professionals) decision in a spasticity center before involving the patient into ITB therapy, and follow up in the rehabilitation unit. The severity of spasticity as a consequence of brain injury can change during years and it is necessery to follow it with dosage and dynamics of baclofen therapy. Baclofen pump removal is suggested if the ITB therapy is further not reasonable.]
