Opis:: Introduction: Meniere’s disease is a condition characterized clinically by episodes of vertigo, hearing loss, tinnitus, and a sensation of fullness in the ear. The symptoms are caused by the endolymphatic hydrops. Despite numerous studies, the exact mechanism of its onset remains unknown. The current diagnostic criteria published by international societies are based on clinical symptoms. Due to the variable clinical presentation of the disease, there is a need to search for effective diagnostic tools. Material and methods: The article discusses various methods assessing inner ear function in the diagnosis of Meniere’s disease, including video Head Impulse Test, videonystagmography with caloric tests, vestibular evoked myogenic potentials, dynamic posturography, and electrocochleography. The results of aforementioned tests with patterns typical for Meniere’s disease are also presented. Conclusions: This article presents a comprehensive diagnostic review of Meniere’s disease using vestibular organ examination methods, emphasizing the importance of various research methods for an accurate understanding and diagnosis of this complex disease.

Opis:: Introduction: The aim of the study was to attempt to analyze the most common causes leading to dizziness, vertigo and balance disorders according to gender and age. Material and methods: Analysis of medical records and evaluation of VNG tests were performed on 608 patients of the private ENT practice “VERTIGO” in Opole between 2011 and 2017, including 404 women and 204 men. The patients’ age was in the range from 18 to 85 years, average age 49.88 years. The following parameters were taken into account in the analysis: the result of the subjective examination and the basic ENT and otoneurological examination, videonystagmographic examination, hearing assessment (tonal and impedance audiometry) and imaging tests (head MRI/CT and cervical spine x-ray), assessment of doppler ultrasound examination of vertebral arteries flow. Results: In examinations patients dizziness and vertigo were more common in women (66.45%) than men (33.55%), the most numerous was group of patients over 60 years, i.e. 30, 76%, systemic ver-tigo predominated (61.02%). Hypertension was the most common chronic disease in the entire popu-lation of patients with dizziness, vertigo and balance disorder and its frequency increases with age, which translates into an increase in the frequency of non-systemic and mixed dizziness reported by patients. The frequency of lipid metabolism disorders increases statistically significantly with age, while thyroid dysfunction as well as migraines and frequent headaches are significantly more com-mon in women reporting dizziness, vertigo and balance disorder than in men. In doppler ultrasound examination, while with age the frequency of bilateral disorders in vertebral artery flow increases significantly. The percentage of individual diagnoses in the examined patients was as follows: ves-tibular disorder (35.86%), benign paroxysmal positional vertigo (18.9%), mixed vertigo (16.12%), cervical vertigo (5.42%), Méniére's disease and its suspicion (5.1%), vertigo and dizziness of central origin (3.78%), vascular vertigo (2.8%), vestibular neuritis (2.3%), post-traumatic dizziness (1.32%) and the cerebellopontine angle tumors (0.16%). In the VNG study: in visual-oculomotor tests an in-crease in the percentage of pathology with age between 51 and 60 years old. Conclusions: The structure of diagnoses made in private practice differs from public health care. This results from the fact that the patient with acute symptoms first goes or is transported to the hospital emergency department. The second reason is the cost of diagnostics in the private sector which is not affordable to every patient.

Opis:: Introduction: The aim of the work was to evaluate one-time recording of ENG and VNG in healthy subjects selected for the given diagnostic tests with reference to the sensitivity and usefulness of this kind of testing in vertigo diagnostics. Material and methods: The tests covered 50 healthy subjects, including 24 women and 26 men aged 20-22 (the mean age of 20,5 years) who did not report any inconvenience from otorhinolaryngological organs and the conducted interview did not reveal any balance disorder or vertigo. Every patient underwent otoneurological subjective and objective tests, electronystagmography (ENG), including a calibration test, head-tracking test, optokinetic nystagmus test, rotatory chair test, positional tests according to Cawthorne and Rose, a Hallpike caloric test as well as videonystagmography which included a calibration test, spontaneous nystagmus evaluation, head-tracking test, positional tests according to Cawthorne and Rose with a head rotation test and Hallpike caloric test. The above tests were performed separately, 24 hours one by one. One-time recording of ENG and VNG was made 48 hours following the last test while each of the two tests was preceded by an additional calibration test. The final recording included the spontaneous nystagmus evaluation, positional tests according to Cawthrone and Rose together with the head rotation test and Hallpike caloric test. Results: Any negative mutual influence of the conducted tests has not been observed. Both in the one-time and separate recording, the caloric test revealed lower values of the mean velocity of the nystagmus free phase in ENG with relation to VNG. No signs from spontaneous nystagmus, as well as optokinetic and positional nystagmus, could be found in any case. Conclusions: The conducted tests did not show any possibility of mutual exclusion of the given ENG and VNG diagnostic tests one-time recording. However, their use in diagnostics of balance disorders and vertigo requires further studies

Opis:: Wprowadzenie: Celem pracy była ocena jednoczasowego zapisu badania ENG i VNG u osób zdrowych dla wybranych testów diagnostycznych pod kątem czułości i przydatności tego rodzaju badania do diagnostyki zawrotów głowy. Materiał i metody: Badania wykonano u 50 osób zdrowych, w tym 24 kobiet i 26 mężczyzn, w wieku 20-22 lata (średnia 20,5 roku), które nie zgłaszały dolegliwości ze strony narządów otorynolaryngologicznych i bez zaburzeń równowagi i zawrotów głowy w wywiadzie. U wszystkich chorych wykonano badanie podmiotowe i badanie przedmiotowe otoneurologiczne, badanie elektronystagmograficzne (ENG), w tym kalibrację, próbę wahadła, badanie oczopląsu optokinetycznego, test fotela wahadłowego, próby położeniowe wg Cawthorne’a i Rosego, próbę kaloryczną wg Hallpike’a, oraz badanie wideonystagmograficzne (VNG), które obejmowało kalibrację, ocenę oczopląsu samoistnego, próbę wahadła, testy położeniowe wg Cawthorne’a i Rosego, rozszerzone o test skrętu szyi, próbę kaloryczną wg Hallpike’a. Wyżej wymienione badania przeprowadzono najpierw oddzielnie, w odstępie 24 godzin. Jednoczasowy zapis ENG i VNG wykonano po 48 godzinach od badań poprzednich, co poprzedzone zostało wykonaniem ponownej kalibracji dla obu zapisów. Wspólny zapis obejmował ocenę oczopląsu samoistnego, testy położeniowe wg Cawthorne’a i Rosego, rozszerzone o test skrętu szyi, próbę kaloryczną wg Hallpike’a. Wyniki: Nie stwierdzono wzajemnego negatywnego wpływu jednego rodzaju badania na drugie. W teście kalorycznym, zarówno w zapisie jednoczasowym, jak i wykonanym oddzielnie, zaobserwowano niższe wartości średniej prędkości wolnej fazy oczopląsu w badaniu ENG w stosunku do badania VNG. W żadnym przypadku nie stwierdzono cech obecności oczopląsu samoistnego, jak również oczopląsu optokinetycznego i położeniowego. Wnioski: Z przeprowadzonych badań wynika, że jednoczasowe zapisy wybranych testów diagnostycznych za pomocą ENG i VNG wzajemnie się nie wykluczają i mogą być wykorzystane w diagnostyce zaburzeń równowagi i zawrotów głowy, co wymaga dalszych badań.

Opis:: Objectives: Vertigo is a very common symptom mainly caused by the lesion of vestibular system (peripheral or central) and often accompanied by some work-related diseases and occupational intoxications. The aim of this study was to assess the value of electronystagmography (ENG) and videonystagmography (VNG) for diagnosing vertigo of various origin. Materials and Methods: The study included four groups, 25 subjects each, of patients suffering from vestibular disorders of peripheral, central and mixed origin versus healthy controls. All were examined by means of ENG and VNG, using the bithermal caloric test with 30°C and 44°C air irrigations of the ears. The findings (frequency of induced nystagmus FRQ, its slow phase velocity SPV, canal paresis CP, directional preponderance DP, vestibular excitability VE) were analysed and compared. Results: In all patients with vertigo due to vestibular neuritis, barotrauma and kinetosis, significant CP, the important sign of peripheral site of vestibular lesion was identified both in ENG and VNG. None of the patients with central origin disorders showed CP in VNG; in the majority of cases DP was observed. However, in ENG we found CP in 5 patients with central origin disorders. There were no essential differences between ENG and VNG in measurements of FRQ and SPV except for higher values in VNG in controls and patients with mixed vertigo. Conclusions: The results suggest that the VNG should be recommended in preference as the valuable method to assess vertigo and to discriminate between the peripheral and the central vestibular lesions.

Opis:: Background: The causes of vertigo are diverse, and the possible differential diagnosis is extensive. Thiamine deficiency after sleeve gastrectomy is one of the rare causes for vertigo, a condition called Wernicke’s encephalopathy. Case report: This is a case report of a 20-year-old female complaining of continuous vertigo for 2 months duration. She complained about ocular, lower limbs and Gastero-intestinal clinical features after undergoing sleeve gastrectomy. She was conscious but confused. Eye movement examination revealed horizontal and vertical nystagmus. She displayed signs of ataxia. VNG revealed Up-beating nystagmus in primary gaze, leftward gaze, and upward gaze when vision is accessible, and in upward gaze when vision is denied suggesting a central etiology. Lab. tests confirmed a low serum thiamine and Vit D levels. Low thiamine raises the suspicion of Wernicke’s encephalopathy. Within 72 hours of treatment, here vertigo and ataxia began to improve, and the nystagmus reduced significantly. Over the next few days, here balance and coordination greatly improved, and here mental state improved. Conclusion: This case underscores the significancy of considering Wernicke's encephalopathy in the differential diagnosis of vertigo, especially in patients with a history of bariatric surgery, regardless of age. It also emphasizes the need for prompt thiamine supplementation in such cases, as timely intervention along with supportive treatments can significantly improve patient outcomes. Otolaryngologists should maintain a broad perspective when diagnosing vertigo to ensure accurate and effective treatment.
