[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.]

[ANTI-VEGF THERAPY WITH BEVACIZUMAB IN BREAST CANCER]

TÓTH Judit, GONDA Andrea, SZÁNTÓ János

[The growth of new blood vessels, angiogenesis is important for tumour progression and metastasis. Vascular endothelial growth factor (VEGF) plays multiple roles in cancer development. Due to it the VEGF seems to be an optimal therapeutic target in breast cancer therapy. The plasma level of this growth factor is highest early in disease suggests that anti-VEGF agents may provide their greatest benefit in firts-line chemotherapy with metastatic breast cancer (MBC). A phase III trial, E2100 evaluated weekly paclitaxel with or without bevacizumab (Avastin), the specific humanised anti-VEGF monoclonal antibody in patients with previously untreated locally recurrent or MBC, doubling of progressionfree survival for all patient subgroups. Bevacizumab is generally well tolerated. The most common adverse events observed in trials hypertension, proteinuria, and wound-healing complications, most of which are grade 1-2 in severity. The registration of bevacizumab for MBC therapy brings new hope for patients. Novel approach of bevacizumab for MBC would be combination chemotherapy and different targeted therapies. Phase III clinical trials of bevacizumab are ongoing in different stages in different settings.]

[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.]

[Interdisciplinary approach of vestibular system impairment]

PONGRÁCZ Endre

[In the first part of this review the definition of vertigo/dizziness was discussed. The major difference between the two signs is the exsistence of the direction, which is specific for vertigo. Dizziness is a frequent complaint in the clinical practice. Its frequency is increasing with advance of age, to intimate the play of declining cognitive process in the pathogenesis of its. The popular health significance of vertigo is in the rowing number of the patients. The onset of the most cases with acute vertigo appears between secundums and minutes so the patients will be provided in circumstances of emergency department. First of all three form schould be take into account: neuronitis vestibularis, benign paroxysmal positional vertigo and Meniere syndrome. Without tipical periferal signs of vertigo, central cause should be searched, principally stroke (lysis possibility). The differential diagnose of the different dizzeness/vertigo forms according to the elapsed time of the onset or congenital and acquired nystagmus was created in tables. The recommendations of the therapy of acute and chronic dizziness/ vertigo syndroms are, lack of results of evidence based trials doubtful. The more often used drugs based on clinical trials are discussed as vinpocetine, betahistine and piracetam. The in vitro and in vivo data suggest that the last molecule is eligible to use both in periferal and central type of vertigo syndroms.]

[Paradigm shift in management of patients with vertigo and imbalance]

MIKE Andrea, TAMÁS T. László

[Dizziness is one of the most common causes of medical visits. Management of the dizzy patient may be challenging both for the general practitioner, in emergency departments, and special clinics, as behind a seemingly homogeneous clinical presentation several very different etiologies may occur. Research of the last two century enriched our knowledge about physiology and pathophysiology of the vestibular system. Much knowledge is now available about the labyrinth being able to sense head motions and gravity, processing of afferent vestibular stimuli, reflectory oculomotor and postural control, or recovery of the vestibular system. Based on scientific results new beside tests have been introduced including provocation maneuvers for detecting ectopic otoliths in different semicircular canals, head impulse test to examine function of the vestibulo-ocular reflex, and the HINTS+ battery for differentiation of peripheral or central origin of an acute vestibular syndrome. Technical innovations like videooculography and vestibular evoked myogenic potentials enable us to selectively and side-specifically examine the function of all six semicircular canals and two otolith organs. Pathomechanism of disorders with vertigo and dizziness became more clear resulting in the development or amendment of diagnostic criteria of several vestibular disorders including vestibular migraine, Menière’s disease, benign paroxysmal positional vertigo, persistent postural-perceptual dizziness, bilateral vestibulopathy. Broader knowledge about the pathomechanism promoted the development of new therapeutic methods like different repositioning maneuvers in benign paroxysmal positional vertigo, pharmaceutical therapies, vestibular rehabilitation, and psychotherapy. We aimed to summarize the novelties in the field of oto-neurology.]

[DIZZINESS - VERTIGO WARNING SYMPTOMS IN VERTEBROBASILAR ISCHEMIA PART II.]

FAZEKAS András

[Dizziness and vertigo - like headache - are the most common complaints which lead patients to visit the doctor. In spite of the headache - which may be primary (e.g. migraine) or symptomatic - dizziness and vertigo do not appear to be a separate nosologic entity but rather the symptoms of several neurological disorders. For differential diagnosis, interdisciplinary thinking and activity is needed because the vestibular, neurological and psychiatric disorders might have a common role in the development of symptoms and further overlapping can also occur. The vascular disorders of the vertebrobasilar system are discussed in detail in this review. The importance, occurrence and causes of vertigo as a warning symptom is in the focus. The author draws attention to life-threatening conditions with acute onset in cases of the posterior scale ischemia and emphasizes the importance of the correct and early diagnosis. The author tries to clear up the nihilistic aspect in treating of stroke and stresses the necessity of thrombolysis and interventional radiological procedures which may be the only chance for the recovery of the patients. The pharmacological prevention of recurrent vascular events is also important and obligatory for the clinicians.]

[Vertigo - comorbidity with psychiatric disorders]

FAZEKAS András

[Vertigo is one of the most common symptom and complaint in the clinical practice. The differential diagnosis can only be attained by a careful interdisciplinary way of thinking and activity, given the fact that the vestibular, neurological and psychiatric disorders - considered as pathogenic factors - are being present simultaneously in triggering the symptoms, and there can be overlaps between the certain pathological processes. The author deals with the co-morbidity of the vertigo and the psychiatric symptoms - anxiety, panic-disorder -, pointing out the common neurobiological and neurophysiological factors in the background of the symptoms, emphasizing the importance of the SSRI-s in the restoration of the serotonerg dysfunction.]
