Filter by:Vertigo is a common complaint in the Emergency Department (ED). The differential diagnosis of central and peripheral vertigo is a difficult issue that directly affects mortality. Magnetic resonance imaging (MRI) is the preferred diagnostic tool, but may not be suitable in all patients due to logistic and economic conditions. In this study, the investigators evaluated the role of thiol/disulfide homeostasis (TDH) parameters and ischemia modified albumin (IMA) levels to assist in the value of being used instead of MRI.
This study evaluated the value of using copetin and protein S 100 b to eliminate the diagnosis of stroke in patients presenting with vertigo in emergency departments. All patients benefited from the S 100b protein assay, copeptin and brain MRI.
The primary aim of this study is to determine whether the prevalence of neuroticism, anxiety and body vigilance is higher in patients diagnosed with PPPD compared to those who suffered a vestibular insult but did not develop PPPD and healthy controls. An increased prevalence of one or more of these factors may identify them as risk factors in the development of PPPD. The secondary aim is to understand how PPPD affects quality of life.
Treatment of vertigo after removal of a tumor of the balance and hearing nerve after neurosurgery, which damages or cuts the vestibular nerve (balance). This trial explores the efficacy and safety of AM-125 in the treatment of acute vertigo. In this proof of concept trial patients experiencing vertigo after neurosurgery (vestibular schwannoma labyrinthectomy and vestibular neurectomy) will receive AM-125 or placebo. It evaluates the potential of AM-125 versus placebo in reducing the symptoms of vestibular dysfunction and accelerating vestibular compensation following neurosurgery.
Comparison of treatment efficacy of a mechanical rotational chair (TRV-chair) vs. manual repositioning maneuvers in BPPV
The vestibular system in the inner year is an important system in the body which is responsible for balance. In addition, there is evidence that the vestibular system plays a role in maintaining blood pressure while changing body position, such as moving from lying down in bed to sitting. Dysfunction of the vestibular system may affect the ability to maintain blood pressure, therefore the aim of this study is to assess if a specific problem in the vestibular system (Benign Paroxysmal Positional Vertigo- BPPV) may cause changes in the interaction between the vestibular system and the cardiovascular system. We assume that patients with this medical condition (BPPV) will have different heart rate parameters in comparison with healthy patients.
The benign paroxysmal positional vertigo (BPPV) is a type of peripheral vertigo characterized by the accumulation of otoliths debris, which are particles resulted from the condensation of endolymph in the inner ducts of semicircular canals (duct lithiasis or canalithiasis). In order to detect the BPPV, a simple test is utilized. The Dix-Hallpike test consists in lay the individual in a quick change in the position of the head. The maneuver is performed, essentially, towards the side in which the patient alleges dizziness in the course of the change in the position of the head. If the individual report vertigo related or no to nystagmus, the test is considered as positive . The osteopathy is a science, which has specific methods of diagnosis and treatment, and has begun to be developed by the physician Andrew Taylor Still at the end of 19th century, which aim is to rebalance the activities of the organism. Accord to the osteopathy science, all the physiological structures in the organism integrating and requires functional and structural harmonization in order to improve the health of the whole body. The main objective of the treatment is to obtain the intertissue mobility, which is considered by osteopathy as a somatic dysfunction, when it is restricted. Samutt confirms that cranial dysfunction of the temporal bones in internal/external rotation may modify the orientation of the semicircular canals, provoking vertigo. Liem propose that the mobilization of the eyeball may be a sensory stimulus of the vestibulo-ocular pathways. For him, maneuvers to the eyeball assists to balance the tonus of extraocular muscles and creates fascial influences on the optic nerve and the oculomotor, and, thus, stimulates the vestibular nuclei. It also suggests that the tension of the cerebellar tentorium and the mobilization of the temporal bones have effects on the structures that composes the vestibule. Thereby, the present work investigated the effect of the cranial osteopathic techniques on the Benign Paroxysmal Positional Vertigo.
IRM-DU is a prospective observational single center study conducted in an emergency department to evaluate the impact of a MRI scanner exclusively dedicated to emergency in the clinical management of patients presenting with dizziness or diplopia. The study will compare 2 strategies : after and before availability of a MRI scanner dedicated to emergency. The primary endpoint is the proportion of patients with a diagnosis of stroke confirmed by imaging (MRI or Computed tomography (CT)) in the group "before implementation of the emergency MRI scanner" and the group "after implementation of the emergency MRI scanner". The hypothesis is that the availability of a MRI scanner dedicated to emergency will improve the diagnosis of stroke in patients presenting with dizziness or diplopia, and will reduce Emergency Department stay, hospital stay and hospitalisation costs.
Benign paroxysmal positional vertigo (BPPV) is one of the most common types of vertigo, especially in elderly. Therefore the investigators have set the goal to evaluate the prevalence of BPPV and its therapy using the Rotundum device in elderly living in retirement homes. Furthermore the investigators use a questionnaire to evaluate possible predictive signs to improve the diagnosis of this disease.
To investigate which treatment option (reposition maneuver) with the TRV chair that is the most effective in patients diagnosed with benign paroxysmal positional vertigo (BPPV). Subtypes of BPPV will be examined after randomization to specific treatments.
