[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.]

[The role of transcranial magnetic stimulation in clinical diagnosis: facial nerve neurography]

ARÁNYI Zsuzsanna, SIMÓ Magdolna

[Facial nerve neurography involving magnetic stimulation techniques can be used to assess the intracranial segment of the facial nerve and the entire facial motor pathway, as opposed to the traditional neurography, involving only extracranial electric stimulation of the nerve. Both our own experience and data published in the literature underline the value of the method in localising facial nerve dysfunction and its role in clinical diagnosis. It is non-invasive and easy to perform. Canalicular hypoexcitability has proved to be the most useful and sensitive parameter, which indicates the dysfunction of the nerve between the brain stem and the facial canal. This is an electrophysiological finding which offers for the first time positive criteria for the diagnosis of Bell’s palsy. The absence of canalicular hypoexcitability practically excludes the possibility of Bell’s palsy. The technique is also able to demonstrate subclinical dysfunction of the nerve, which can be of considerable help in the etiological diagnosis of facial palsies. For example, in a situation where clinically unilateral facial weakness is observed, but facial nerve neurography demonstrates bilateral involvement, etiologies other than Bell’s palsy are more likely, such as Lyme’s disease, Guillain-Barré syndrome, meningeal affections etc. Furthermore, the technique differentiates reliably between peripheral facial nerve lesion involving the segment in the brain stem or the segment after leaving the brainstem.]

[MOOT-COMP study - Compliance of patients with antiporotic treatment]

BORS Katalin, BOROS Erzsébet

[INTRODUCTION - Several studies prove the importance of the lack of compliance in the ineffectiveness of drugs which have been tested by clinical studies. In our study we finded the reasons of leaving off the antiporotic treatment. PATIENTS AND METHODS - 1067 osteoporotic patients (91% women, 9% men) were enrolled to examine compliance and to find explanation of non-compliance. We asked the patients about medications, exercises, electrotherapy and medical aids. RESULTS - Medications were recommended for most patients and exercise was the secondary most common therapeutic method. Electrotherapy was prescribed for one third and medical aids were recommended for one fifth of the recruited patients. Two third of patients reported to take all pills, most of them suffered from bone fracture. More than one fifth of patients sometimes or often forgot to take the treatment. 10% more patients did exercises than it was recommended by the practitioner. However, only 25% of all patients did exercises appropriate frequency and at least 20 minutes per day. Electrotherapy was not prescribed by the doctors for more than half of patients on this treatment. Medical aids were not used by 10% of patients despite the recommendations. Almost one third of the enrolled patients reported a fact which disturbed keeping recommendations of the doctors. These facts were financial problems, long waiting lists and low motivation of patients for keeping recommendations. The compliance did not correlate with education and social status. The patients with multiple fractures were more comply with medications and exercises. CONCLUSION - Drawing the informed patient into decision making and knowing the therapeutic outcome are important factors for keeping therapeutic recommendations. The high fracture rate in Hungary attracts our attention for enhance patient compliance.]

[CHANGES IN EEG-COMPLEXITY AFTER SUBCORTICAL ISCHEMIC BRAIN DAMAGE]

MOLNÁR Márk, CSUHAJ Roland, HORVÁTH Szabolcs, VASTAGH Ildikó, GAÁL Zsófia Anna, CZIGLER Balázs, BÁLINT Andrea, NAGY Zoltán

[Introduction - Complexity analysis of the EEG is a relatively new field in theoretical and cinical electrophysiology. The authors present results of EEG-analysis in a patient with stroke, utilizing the sensitivity of the new procedures with respect to linear and nonlinear synchronization. Participants and methods - The EEG (19 channels) was recorded in a patient with subcortical unilateral ischaemic completed stroke involving the frontoparietal white matter while leaving the cortex intact and in 12 healthy controls in eyes open and in eyes closed conditions. Results - In the patient, increased Omega-complexity was found in slow (delta, theta) and lower alpha frequencies in the side of the stroke and in high frequencies (beta2 in eyes closed, alpha2, beta1 and beta2 in eyes open conditions) in the intact side. Synchronization likelihood was higher in the ischaemic side in the beta2 (eyes closed) and both in the beta1 and beta2 (eyes open) frequencies. Increasing Omega-complexity caused by eyes opening was markedly reduced in the patient in the beta frequencies compared to that seen in the controls. The difference was more conspicuous in the side of the infarct and involved not only the beta but also the alpha frequencies as well. Opening the eyes decreased synchronization likelihood in all frequency bands in the controls and also in the patient except the alpha2, beta1 and beta2 bands in the side of the lesion. Conclusions - The increased Omega-complexity and decreased synchronization likelihood in the slow frequencies in the infarcted side is probably the result of lesioned interneuronal connections lowering the level of cooperation of neuronal systems involved in this type of activity. The increased Omega-complexity and decreased synchronization likelihood caused by eyes opening could not be observed in the beta and alpha frequencies in the side of the lesion, possibly caused by damaged thalamocortical connections.]
