<p class="MsoNormal"><span lang="EN-US">Good health is not only a privilege of young generation but also of elderly people. Nowadays 13% of the population has reached the age of 65, and one third of them have vertiginous attack at least once in their life. 45-70% of the elderly has one or more drop attacks yearly<strong>.</strong></span><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">In the Semmelweis University Otoneurological Department, 17% of the patients are more than 65 years old. Detailed audiological and otoneurological examination was performed.</span></p>
<p class="MsoNormal"><span lang="EN-US">The origin of vertigo was extravestibular, like depression and anxiety disorder in 28% of the patients and vascular in 42%. Only in 30% specific balance system disease was observed.</span></p>
<p class="MsoNormal"><span lang="EN-US">Together with presbyacousia a slight loss in balancing appears. Gradually, elderly patients start noticing some unsteadiness or fear to keep moving. The presbyvertigo and presbyataxia are caused by the slow degeneration of vestibular end organs and brainstem pathways. The deterioration of sensorial organs and the central signal processing problems mean that our brain is getting old due to age. </span></p>
<p class="MsoNormal"><span lang="EN-US">The reasons of the old age vertigo are the decreased physical activity, concomitant diseases, increasing occurrence of vascular risk factors, degeneration of the cervical mechanoreceptors, and anxiety disorders with depression. The possibilities of the treatment: vasoactive and neuroprotective drug administration, adequate treatment of the concomitant diseases. The early mobilization of patients with vertigo is very important so as to avoid sedative drug administration.<span>  </span></span></p>

<p class="MsoNormal"><span lang="EN-GB">Patients of whiplash trauma report to a neurootologist<span> </span>with complaints of long standing duration like vertigo, instability,<span> </span>especially on neck movements, vegetative symptoms like nausea, and also auditory symptoms like tinnitus and hearing loss. In addition they complain of neck pain, strain and stiffness.</span></p>
<p class="MsoNormal"><span lang="EN-GB">The mechanism of triggering vertigo from the neck is partly explained by work of Barre´ and Lieou. The trauma causes an over excitation of cervical proprioceptors resulting in hyper tonicity of gamma fibres and sympathetic nerves of the neck triggering thus the vertigo and vegetative symptoms. However there is also intracranial trauma due to movement of brain within the skull thus affecting the brainstem and the supratentorial structures.</span></p>
<p class="MsoNormal"><span lang="EN-GB">In our study we studied the caloric responses in these patients by means of Claussen’s caloric test and the butterfly chart. With respect to the post traumatic vertigo due to whiplash mechanisms, the monaural caloric vestibulo-ocular test by means of butterfly chart could detect 33% of the cases as normal and 67% as pathological.The most frequent types of the 10 pathological butterflies show that the majority of the pathologies are related to brainstem dysfunctions like major and minor brainstem disinhibitions.</span></p>

<p class="MsoBodyText"><span lang="EN-GB">Specific chemical intoxications in the inner ear can arise from aminoglycosidic antibiotics. For this paper two samples of 485 patients after treatment with streptomycin and 23 patients after treatment of gentamycin have been randomly selected.</span></p>
<p class="MsoNormal"><span lang="EN-GB">The amount of vertigo complaints was more than double as high in the group with gentamycin. This also kept on with the nausea complaints and with the so called vertigo releasing factors.</span></p>
<p class="MsoNormal"><span lang="EN-GB">With respect to the hearing complaints the streptomycin group reported about tinnitus in 17,32%. This occurrence was double as high as with gentamycin, i.e. 37,48%. Subjective hearing loss was complained with streptomycin in 25,98% and with gentamycin in 34,78%.</span></p>
<p class="MsoNormal"><span lang="EN-GB">The neurootological examination with an equilibriometric test battery unveiled a higher activity of the spontaneous nystagmus ENG in lying position with streptomycin and sitting position with gentamycin. The Claussen butterfly calorigrams nearly showed the same amounts of pathology with streptomycin as well as with gentamycin. This also holds for the VESRIC. The most sensitive equilibriometric test is the stepping CCG. But the stepping test recorded by the craniocorpogram (CCG) showed 63% of vestibular spinal pathology with streptomycin and 73% pathology with gentamycin.</span></p>
<p class="MsoBodyText"><span lang="EN-GB">Concerning the complaints about hearing disturbances speech audiometry approximately shows the same amount of pathology with streptomycin as with gentamycin.</span></p>
<p class="MsoNormal"><span lang="EN-GB">But pure tone audiometry proves by the trend that all the threshold measurements are worse with gentamycin than with streptomycin.</span></p>
<p class="MsoNormal"><span lang="EN-GB"> For measuring the disturbances it is most favourable to apply step test CCG for equilibriometry and the pure tone audiometry for dealing with hearing deficits.</span></p>

<p class="MsoNormal"><span lang="EN-GB">With electro-cochleography, brainstem audiometry and cortical response audiometry it was possible to record potentials from the inner ear, the brainstem and the auditory cortex.

<p class="MsoNormal"><span lang="EN-GB">Since now, cortical projections of the vestibular system are known and as it has been proved since more than 20 years, that there exist the possibility of vestibular evoked potentials, which then leads to detect that the dwelling point of the tinnitus in the area 41 of the temporal lobe of human cortex.</span></p>
<p class="MsoNormal"><span lang="EN-GB">The typical caloric butterfly patterns of «2002» or «0220» are pointing to the same area.<span>  </span>Thus the acoustic and the vestibular approaches towards tinnitus of the cortical type are clinically investigated by cases of the Bad Kissingen databanks NODEC.</span></p>

			<content:encoded><![CDATA[<p>By Definition HEMANGIOBLASTOMA is a benign tumor that may develop on the nervous system that may occur sporadically or in association with Hippel-Lindau disease. It accounts for approximately 2% of intracranial tumors, arising most frequently in the cerebellar hemispheres and vermis. Histologically, the tumors are composed of multiple capillary and sinusoidal channels lined with endothelial cells and clusters of lipid-laden pseudoxanthoma cells. Usually solitary, these tumors can be multiple and may also occur in the brain stem, spinal cord, retina, and supratentorial compartment. Cerebellar hemangioblastomas usually present in the third decade with intracranial hypertension, and ataxia. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2071-2)</p>
<p>We report  one patient with headache and symptoms of cerebellum involvement.</p>
<p>MRI showed a cerebellar large mass compatible with hemangioblastoma.</p>
<p>Often causing gradual hearing loss, tinnitus  and dizziness.If the tumor becomes large, it can interfere with the facial nerve, causing partial paralysis, and eventually pressing against brain structures, becoming life-threatening,</p>
<p>The diagnosis must be early, an hemangioblastoma is key to preventing its serious consequences. Unfortunately, early detection of the tumor is sometimes difficult, because the symptoms may be subtle and may not appear in the beginning stages of growth. Also, hearing loss, dizziness, and tinnitus are common symptoms of any middle and inner ear problems. Therefore, once the symptoms appear, a thorough ear examination and hearing test are essential the study the vestibular function through of vestibuloespinal, retinalocular, vestibuloocular systems in the Cranio-Corpo-Graphy (CCG), the Test of Balance(TOB) and the Computarized Electronystagmography (CNG).  in order to determine and orientate a better vestibular diagnosis. Computerized tomography(CT) and magnetic resonance imaging (MRI) are helpful in determining the location and size of a tumor and also in planning its removal.</p>

			<content:encoded><![CDATA[<p>If onset of vertigo could be known before, patients could control the attack. That would be of benefits to those patients. At the NES conference in Bad Kissingen the year before last I showed that vertigo patients with higher heart rate would be sensitive to rapid change in the atmospheric pressure. In order to avoid vertigo attack, do those patients have to be nervous about the weather forecast every day?  </p>
<p>Therefore, other easier methods for prediction of vertigo attack should be desirable. Body signs such as chills, shoulder stiffness and so on were paid attention on.  In younger patients feelings of shoulder stiffness were one of good indicators for vertigo attack.</p>

			<content:encoded><![CDATA[<p>Meniere&#8217;s disease (MD) is an idiopathic inner ear disorder characterized by fluctuating hearing loss, episodic vertigo and tinnitus. Its aetiology is unknown, although there is growing evidence that autoimmunity may be involved in its development. Our preliminary report investigated the co-occurence of heat shock protein 70 (HSP70) and viral and autoimmune antibodies in subjects affected by MD.</p>
<p>Using the Western blot immunoassay, we examined in thirtheen patients’ sera the reactivity to bovine inner ear antigen (anti-heat shock protein 70 [HSP70] antibodies) and the presence of viral antibodies and autoantibodies (Herpes simplex type 1-2, Herpes Zoster, Cytomegalovirus, Ebstein-Barr IgM and IgG. Cardiolipin, thyroglobulin and thyroperoxidase,antinuclear, antimythocondrial and anti-smooth cell antibodies). Aim of the study was to probe a possible relationship between the presence of anti-HSP70 antibodies and the antibody pattern. Reactivity to HSP70 was found only in 1/13 MD patients (7.7%) and occurred during a  Herpes Zoster (VZV) reactivation.</p>
<p>The occurrence of anti- HSP70 antibodies concomitant to the VZV expression suggests it was probably due to an aspecific polyclonal expression during the infection. No relationship was found between the presence of antibodies to HSP-70 and the immunologic and viral testing.</p>
