[VERTIGO IN NEUROLOGICAL DISEASES]

FAZEKAS András

[Peripheral and central vestibular syndromes are characterized by the combination of the four symptoms such as: vertigo, nystagmus, imbalance and nausea. Vertigo is the disturbance of the cortico-spatial orientation. Nystagmus is regarded as a secondary symptom caused by direction specific disequilibrium of the vestibulo- ocular reflex. Imbalance is caused by the abnormal activation of vestibulo-spinal pathways. Nausea is due to the activation of the medullary vomiting center. It is important that clinicians can establish an adequate diagnosis and differentiate vertigo and dizziness. The author - without the aim of completeness - discusses the types of vertigo caused by the most important disorders of the central nervous system, emphasizing the role of general practitioners in the diagnostic and therapeutic algorhytm.]

[THE PLEIOTROPIC EFFECTS OF LOSARTAN - THE IMPORTANCE OF DECREASING URIC ACID LEVEL]

CSIKY Botond, MARKÓ Lajos, MOHÁS Márton, CSEH Judit, MIKOLÁS Esztella, SZÍJÁRTÓ István, WITTMANN István

[Nowdays the goal of the antihypertensive treatment is to decrease the cardiovascular risk of the patients by treating the associated diseases and possible hypertensive end-organ damages. Losartan is an antihypertensive drug with all these capabilities and placebo-like side-effect profile. Besides the most important effects of losartan, which are mediated by blocking the angiotensin II. type 1. receptors, it also has other, molecule specific beneficial effects. The most important, well documented pleiotropic effect of losartan is its uricosuric effect. The pleiotropic effects together with the blockade of the angiotensin II. receptors are considered more and more important in the hypertensive end-organ protection and in the treatment of associated diseases in hypertensive patients.]

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

Vestibular evoked myogenic potential responses in Parkinson’s disease

CICEKLI Esen, TITIZ Pinar Ayse, TITIZ Ali, OZTEKIN Nese, MUJDECI Banu

Background - Our objectives were to determine the differences in the vestibular evoked myogenic potential (VEMP) responses in patients diagnosed with early staged idiopathic Parkinson’s disease (PD) compared to the normal population and evaluate the vestibular system disorder causing balance-posture disorders. Second aim of this study was to investigate caloric test responses particularly in early staged PD compared to normal popu­lation. Material and methods - Thirty patients (14 females and 16 males; mean age, 60.6 ± 13.1 years) diagnosed with idiopathic PD and 28 healthy subjects (20 males and 8 females; mean age, 59.1 ± 6.4 years) were included. The patient and control groups were subdivided according to their age, gender and the patient group was subdivided according to onset time of the Parkinson symptoms, Hoehn-Yahr staging. The subgroups were compared for VEMP and caloric test responses. Results - There were no significant differences between the study and control groups for right and left VEMP measurements. Patients over 60 years and under 60 years did not show significant differences in terms of right and left mean VEMP measurements. However, P1 amplitude was significantly lower in patients over 60 years old (P = .004). Gender, disease duration, BERG balance scale and Hoehn-Yahr stage had no effect on the VEMP amplitudes. There was no significant correlation with the side of Parkinsonian symptoms to the side of canal paresis (P = .566) and the side on which no VEMP response was obtained in caloric test. Conclusion - VEMP responses were not different between PD and healthy subjects. VEMP P1 amplitude was decreased with age in PD group. Canal paresis and symptoms side were not statistically correlated in caloric test.

[RISKS AND BENEFITS OF MEDICATION IN PREGNANT WOMEN]

CZEIZEL Endre

[The Hungarian Case-Control Surveillance System of Congenital Abnormalities can provide appropriate data for the evaluation of risk and benefits of drugs and pregnancy supplements in pregnant women. Among the main principles, the importance of time factor (the first trimester concept is outdated) and the explanation of frequent false teratogenic findings (e.g. recall bias, chance effect, etc.) are discussed. The main conclusion is that at present the exaggerated teratogenic risk of drugs is much more harmful for the fetus than the rare teratogenic effect of some drugs themselves. Medical doctors and other experts therefore need more education to know the principles and findings of modern human teratology because it may help us to have a better balance between the risks and benefits of drug use during pregnancy. On the other hand, the primary prevention of neural-tube defects and some other congenital abnormalities is demonstrated by periconceptional folic acid or folic acid-containing multivitamin supplementation. Unfortunately, this new method is used rarely and inappropriately (due to the late onset of supplementation) in Hungary.]

[Antiplatelet therapy with acetylsalicylic acid - Cardiovascular indications and haemorrhagic complications]

KISS Nóra, KISS Róbert Gábor

[Acetylsalicylic acid effectively blocks the activation of platelets, and becomes a basic element of antithrombotic therapy of patients with high cardiovascular risk. Decrease of platelet reactivity is due to the irreversible inhibition of COX- 1 isoenzime in platelets during treatment. Choosing the right dose is still not an easy task. Bleeding side effects are frequently seen in patients treated with this drug worldwide. Clinical benefit does not improves with escalated doses (300 mg), however the risk of haemorrhagic events increases. Therefore acetylsalicylic acid dose should be reduced to the effective minimal dose (75-150 mg daily) after the acute phase of atherothrombosis in order to prevent side effects. Effect of acetylsalicylic acid differs individually, it might be important screening out those patients who respond less to the drug. Resistance is still an evolving field, proper methodology is to be determined. Right indications of acetylsalicylic acid needs balance between reaching clinical benefit and avoiding side effects. The Hungarian Cardiovascular Therapeutic Consensus Conference 2009 suggested acetylsalicylic acid in primary prevention for those males only, who have overt cardiovascular risk, and SCORE result is more than 10%, with no gastrointestinal haemorrhage in medical history, and with a well-controlled hypertension. Lifelong aspirin prevention should be used after all diagnosed cardiovascular atherothrombotic event as a cornerstone of secondary prevention with low dose (75-150 mg daily) in both genders.]
