Elicitation of a rotatory nystagmus by stimulating the semicircular canals with water or air which is above or below body temperature. In warm caloric stimulation a rotatory nystagmus is developed toward the side of the stimulated ear; in cold, away from the stimulated side. Absence of nystagmus indicates the labyrinth is not functioning.
An illusion of movement, either of the external world revolving around the individual or of the individual revolving in space. Vertigo may be associated with disorders of the inner ear (EAR, INNER); VESTIBULAR NERVE; BRAINSTEM; or CEREBRAL CORTEX. Lesions in the TEMPORAL LOBE and PARIETAL LOBE may be associated with FOCAL SEIZURES that may feature vertigo as an ictal manifestation. (From Adams et al., Principles of Neurology, 6th ed, pp300-1)
Head Impulse Test
Vestibular Function Tests
Idiopathic inflammation of the VESTIBULAR NERVE, characterized clinically by the acute or subacute onset of VERTIGO; NAUSEA; and imbalance. The COCHLEAR NERVE is typically spared and HEARING LOSS and TINNITUS do not usually occur. Symptoms usually resolve over a period of days to weeks. (Adams et al., Principles of Neurology, 6th ed, p304)
The essential part of the hearing organ consists of two labyrinthine compartments: the bony labyrinthine and the membranous labyrinth. The bony labyrinth is a complex of three interconnecting cavities or spaces (COCHLEA; VESTIBULAR LABYRINTH; and SEMICIRCULAR CANALS) in the TEMPORAL BONE. Within the bony labyrinth lies the membranous labyrinth which is a complex of sacs and tubules (COCHLEAR DUCT; SACCULE AND UTRICLE; and SEMICIRCULAR DUCTS) forming a continuous space enclosed by EPITHELIUM and connective tissue. These spaces are filled with LABYRINTHINE FLUIDS of various compositions.
A syndrome characterized by recurrent episodes of excruciating pain lasting several seconds or longer in the sensory distribution of the TRIGEMINAL NERVE. Pain may be initiated by stimulation of trigger points on the face, lips, or gums or by movement of facial muscles or chewing. Associated conditions include MULTIPLE SCLEROSIS, vascular anomalies, ANEURYSMS, and neoplasms. (Adams et al., Principles of Neurology, 6th ed, p187)
Hearing Loss, Sensorineural
A benign SCHWANNOMA of the eighth cranial nerve (VESTIBULOCOCHLEAR NERVE), mostly arising from the vestibular branch (VESTIBULAR NERVE) during the fifth or sixth decade of life. Clinical manifestations include HEARING LOSS; HEADACHE; VERTIGO; TINNITUS; and FACIAL PAIN. Bilateral acoustic neuromas are associated with NEUROFIBROMATOSIS 2. (From Adams et al., Principles of Neurology, 6th ed, p673)
Caloric value of inulin and oligofructose. (1/58)Dietary carbohydrates, which are absorbed as hexose, (glucose, fructose) have a caloric value of 3.9 kcal/g (16.3 kJ/g), and their cellular metabolism produces approximately 38 mol ATP/mol. However, chicory inulin and oligofructose resist digestion and they are not absorbed in the upper part of the gastrointestinal tract. After oral ingestion, they reach the colon intact where they become hydrolyzed and extensively fermented by saccharolytic bacteria, which produce short-chain carboxylic and lactic acids as electron sinks. Depending on both the degree of their colonic fermentation and the assumptions of the model used, the caloric value of such nondigested but fermented carbohydrates varies between 0 and 2.5 kcal/g. Through the catabolism of the absorbed short-chain carboxylic and lactic acids, they may produce up to 17 mol ATP/mol of fermented sugar moiety. Because the daily intake of these dietary carbohydrates is likely to remain relatively small (<10% and probably often not >5% of total daily calorie intake), it is of low relevance nutritionally to give them a precise caloric value. On the basis of biochemical balance charts for carbon atoms, metabolic pathways and energy yields to the host, the caloric value of a fructosyl residue in chicory inulin and oligofructose has been calculated to be approximately 25-35% that of a fully digested and absorbed fructose molecule. For the purpose of food labeling, it is recommended that chicory inulin and oligofructose, like all the other carbohydrates that are more or less completely fermented in the human colon, should be given a caloric value of 1.5 kcal/g (6.3 kJ/g).

Cerebral representations for egocentric space: Functional-anatomical evidence from caloric vestibular stimulation and neck vibration. (2/58)The internal representation of space involves the integration of different sensory inputs-visual, somatosensory/proprioceptive, vestibular-yielding reference frames which are not based on individual peripheral sensory codes, being organized instead in ego-centred (e.g. head, trunk, arm) and object- or environment-centred coordinates. Lateralized or direction-specific stimulation of peripheral sensory systems, such as caloric vestibular stimulation (CVS), posterior neck muscle mechanical vibration (NV) and optokinetic stimulation, can induce a distortion of egocentric coordinates, causing, for example, a deviation of the subjective straight ahead in pointing tasks. Appropriate forms of this stimulation can also temporarily improve a variety of pathological manifestations of unilateral neglect. We used PET measurements of regional cerebral blood flow changes in normal volunteers to measure the brain responses shared by CVS and NV. We show that somatosensory areas of the perisylvian cortex including the insula and retroinsular cortex, the temporoparietal junction and somatosensory area II receive signals from both sensory channels. We propose that these anatomical sites contribute to egocentric representation of space. (+info)
Neurotoxic mechanism of cinnabar and mercuric sulfide on the vestibulo-ocular reflex system of guinea pigs. (3/58)Cinnabar, a naturally occurring mercuric sulfide (HgS), has been combined with Chinese herbal medicine as a sedative for more than 2000 years. To date, its neurotoxic effect on the vestibulo-ocular reflex (VOR) system has not been reported. By means of a caloric test coupled with electronystagmographic recordings, the effect of commercial HgS and cinnabar on the VOR system of guinea pigs was studied. HgS or cinnabar was administered orally (1.0 g/kg) to Hartley-strain guinea pigs once daily for 7 consecutive days. A battery of electrophysiological, biochemical, and histopathological examinations were performed. The results showed that HgS induced a 60% caloric response abnormality (40% caloric hyperfunction and 20% hypofunction), whereas the abnormal responses appeared to be more severe (six out of six) in the cinnabar group. The Hg contents of whole blood and cerebellum were increased and correlated to their neurotoxic effects on the VOR system, indicating that both insoluble HgS and cinnabar could be absorbed from the gastrointestinal tract and distributed to the cerebellum. Although the vestibular labyrinth revealed no remarkable change under light microscopy, loss of Purkinje cells in the cerebellum was detected, and the enzymatic Na(+)/K(+)-ATPase activity of cerebellum (a higher inhibitory center of the VOR system) was significantly inhibited by HgS and cinnabar. Moreover, cerebellar nitric oxide (NO) production was increased significantly. Hence, we tentatively conclude that the increased Hg contents in the cerebellum following oral administration of HgS and cinnabar were responsible, at least in part, for the detrimental neurotoxic effect on the VOR system. Potentially, decreasing Na(+)/K(+)-ATPase activity and increasing NO production within the cerebellar regulatory center are postulated to mediate this VOR dysfunction caused by the mercurial compounds and cinnabar.

A new light on caloric test--what was disclosed by three dimensional analysis of caloric nystagmus? (4/58)For better understanding of caloric nystagmus, this phenomenon will be reviewed historically in three stages. 1) The first light on caloric nystagmus was thrown by Barany 1906. Through direct observation of eye movements, Barany established the caloric test as an important tool to determine the side of lesion for vertigo. 2) The second light is shed by electrooculogram (EOG) from the late 1950th. EOG enabled qualitative analysis of caloric nystagmus, and proved Barany's convection theory, but resulted in neglect of vertical and roll eye movements. 3) The third light is gained by 3D recording of eye movements started from the late 1980th. 3D recordings of eye movements enabled us to analyze the spatial orientation of caloric nystagmus, and disclose the close correlation of the nystagmus components in the head vertical and the space vertical planes, suggesting a contribution of the velocity storage integrator. The 3D property of caloric nystagmus will be explained in detail. (+info)
Perspectives for the comprehensive examination of semicircular canal and otolith function. (5/58)A review is presented on the three-dimensional aspects of the vestibulo-oculomotor system and the current functional tests for unilateral examination of the individual receptors in the vestibular labyrinth. In the presentation, attention is directed towards the recently developed vestibular tests, which promise a more comprehensive examination of labyrinth function. More explicitly, unilateral tests for the utricle, saccule and the individual semicircular canals are discussed. Caloric irrigation and rotatory testing are widely used as tests for the integrity of the (horizontal) semicircular canals. Little useful diagnosis is made however on the vertical canals, not to mention the otolith organs. A promising approach to the examination of individual semicircular canal function has been described. This involves the perception of self-rotation in each of the planes of the semicircular canals. The patient/subject is rotated by an arbitrary amount on a standard Barany chair and then required to return the chair to its original position, by joystick control of the chair velocity. In order to test the vertical canals, the head of the subject/patient is positioned so that the plane of each canal lies in the plane of rotation. A promising unilateral test of saccular function involves the use of vestibular evoked myogenic potentials. Here it has been demonstrated that the saccules can be activated using brief, high-intensity acoustic clicks. The myogenic potential is measured using surface electrodes over the sternocleidomastoid muscles. Initial data from patients has indicated that the test is specific for unilateral saccule disorders. The unilateral test of utricle function is based on the eccentric displacement profile. Thus, eccentric displacement of the head to 3.5 cm during constant velocity rotation about the earth-vertical axis generates an adequate unilateral stimulation of the otolith organ, without involving the semicircular canals. This paradigm has also proved efficient in localizing peripheral otolith dysfunction by means of SVV estimation. This represents a novel test of otolith function that can be easily integrated into routine clinical testing. In contrast to the otolith-ocular response, the subjective visual vertical also reflects the processing of otolithic information in the higher brain centres (thalamus, vestibular cortex). Exploitation of the two complementary approaches therefore provides useful information for both experimental and clinical scientists. Of direct interest is the finding that testing with the subject rotating on-centre is sufficient to localize peripheral otolith dysfunction by means of SVV estimation. This represents a novel test of otolith function that can be easily integrated into routine clinical testing. In addition to caloric testing, which has remained the classical unilateral test of vestibular function, the newly developed tests should improve the differential diagnosis of vestibular disorders.

Dominance for vestibular cortical function in the non-dominant hemisphere. (6/58)The aim of this (15)O-labelled H(2)O bolus positron emission tomography (PET) study was to analyse the hemispheric dominance of the vestibular cortical system. Therefore, the differential effects of caloric vestibular stimulation (right or left ear irrigation with warm water at 44 degrees C) on cortical and subcortical activation were studied in 12 right-handed and 12 left-handed healthy volunteers. Caloric irrigation induces a direction-specific sensation of rotation and nystagmus. Significant regional cerebral blood flow increases were found in a network within both hemispheres, including the superior frontal gyrus/sulcus, the precentral gyrus and the inferior parietal lobule with the supramarginal gyrus. These areas correspond best to the cortical ocular motor centres, namely the prefrontal cortex, the frontal eye field and the parietal eye field, known to be involved in the processing of caloric nystagmus. Furthermore, distinct temporo-parietal activations could be separated in the posterior part of the insula with the adjacent superior temporal gyrus, the inferior parietal lobule and precuneus. These areas fit best to the human homologues of multisensory vestibular cortex areas identified in the monkey and correspond to the parieto-insular vestibular cortex (PIVC), the visual temporal sylvian area (VTS) and areas 7 and 6. Further cortical activations were seen in the anterior insula, the inferior frontal gyrus and anterior cingulum. The subcortical activation pattern in the putamen, thalamus and midbrain is consistent with the organization of efferent ocular motor pathways. Cortical and subcortical activation of the described areas was bilateral during monaural stimulation, but predominant in the hemisphere ipsilateral to the stimulated ear and exhibited a significant right hemispheric dominance for vestibular and ocular motor structures in right-handed volunteers. Similarly, a significant left hemispheric dominance was found in the 12 left-handed volunteers. Thus, this PET study showed for the first time that cortical and subcortical activation by vestibular caloric stimulation depends (i) on the handedness of the subjects and (ii) on the side of the stimulated ear. Maximum activation was therefore found when the non-dominant hemisphere was ipsilateral to the stimulated ear, i.e. in the right hemisphere of right-handed subjects during caloric irrigation of the right ear and in the left hemisphere of left-handed subjects during caloric irrigation of the left ear. The localization of handedness and vestibular dominance in opposite hemispheres might conceivably indicate that the vestibular system and its hemispheric dominance, which matures earlier during ontogenesis, determine right- or left-handedness.

Treatment of anterior canal benign paroxysmal positional vertigo by a prolonged forced position procedure. (7/58)This report presents a therapeutic procedure for refractory benign paroxysmal positional vertigo (antBPPV) of the anterior canal. Two patients with refractory antBPPV were treated by a prolonged forced position procedure (PFPP). The technique is based on the assumption that the pathophysiological mechanism of antBPPV is similar to that generating posterior canal canalolithiasis. The patients recovered from refractory antBPPV after one or more PFPPs. The rationale for this therapy is that when the patient lies in the proposed forced position, the affected anterior canal is uppermost in an almost gravitationally vertical position. If the patient remains in this position for several hours, the floating particles lying in the non-ampullary arm of the canal can gradually slip out of the canal towards the vestibule due to gravity. We recommend trying PFPP when the side of lithiasis cannot be determined, in cases that are resistant to particle repositioning canal manoeuvres, and before considering canal plugging for refractory antBPPV.

Methylprednisolone, valacyclovir, or the combination for vestibular neuritis. (8/58)BACKGROUND: Vestibular neuritis is the second most common cause of peripheral vestibular vertigo. Its assumed cause is a reactivation of herpes simplex virus type 1 infection. Therefore, corticosteroids, antiviral agents, or a combination of the two might improve the outcome in patients with vestibular neuritis. METHODS: We performed a prospective, randomized, double-blind, two-by-two factorial trial in which patients with acute vestibular neuritis were randomly assigned to treatment with placebo, methylprednisolone, valacyclovir, or methylprednisolone plus valacyclovir. Vestibular function was determined by caloric irrigation, with the use of the vestibular paresis formula (to measure the extent of unilateral caloric paresis) within 3 days after the onset of symptoms and 12 months afterward. RESULTS: Of a total of 141 patients who underwent randomization, 38 received placebo, 35 methylprednisolone, 33 valacyclovir, and 35 methylprednisolone plus valacyclovir. At the onset of symptoms there was no difference among the groups in the severity of vestibular paresis. The mean (+/-SD) improvement in peripheral vestibular function at the 12-month follow-up was 39.6+/-28.1 percentage points in the placebo group, 62.4+/-16.9 percentage points in the methylprednisolone group, 36.0+/-26.7 percentage points in the valacyclovir group, and 59.2+/-24.1 percentage points in the methylprednisolone-plus-valacyclovir group. Analysis of variance showed a significant effect of methylprednisolone (P<0.001) but not of valacyclovir (P=0.43). The combination of methylprednisolone and valacyclovir was not superior to corticosteroid monotherapy. CONCLUSIONS: Methylprednisolone significantly improves the recovery of peripheral vestibular function in patients with vestibular neuritis, whereas valacyclovir does not. (+info)

Isolated nodular infarction and vestibular neuritis
An isolated nodular infarction presenting as an isolated vertigo with unidirectional, gaze-fixed nystagmus has not been previously reported. We reported a patient with cerebellar infarction who presented with purely isolated vertigo, ipsilesional, spontaneous nystagmus, and contralesional axial lateropulsion without usual symptoms or signs of cerebellar dysfunction. An MRI of the brain showed a small infarct selectively involving the nodulus. A pure vestibular syndrome in our patient may be explained by an ipsilateral involvement of nodulo-vestibular inhibitory projection to vestibular nucleus. Clinicians should be aware of the possibility of a nodulus infarction in patients with an acute vestibular syndrome, even if the pattern of nystagmus and lateropulsion is typical of vestibular neuritis. ...

Objective: Vestibular signals are involved in higher cortical functions like spatial orientation and its disorders. Vestibular dysfunction contributes, for example, to spatial neglect which can be transiently improved by caloric stimulation. The exact roles and mechanisms of the vestibular and visual systems for the recovery of neglect are not yet known. Methods: Resting-state functional connectivity (fc) magnetic resonance imaging was recorded in a patient with hemispatial neglect during the acute phase and after recovery 6 months later following a right middle cerebral artery infarction before and after caloric vestibular stimulation. Seeds in the vestibular [parietal operculum (OP2)], the parietal [posterior parietal cortex (PPC);7A, hIP3], and the visual cortex (VC) were used for the analysis. Results: During the acute stage after caloric stimulation the fc of the right OP2 to the left OP2, the anterior cingulum, and the para/hippocampus was increased bilaterally (i.e., the vestibular ...

What are Nucleotides and How do they Affect Performance and Immunity? - FlashBerg
We often think of the body as a system that runs on caloric energy obtained through the carbohydrates, proteins, and fats that make up our diets. This is true
IMHO: A couple of articles
The problem that I see with most fad diets is that they sacrifice balance. For example, on a low or no-fat diet, you could eat a 50 lb. bag of sugar - or on a low or no-carb diet, you could eat a 50 lb. can of lard. In both cases you are within the parameters of the diet, but its not very healthy. The human body developed a taste for fats and sugars because those two nutrients provided the highest per unit caloric value. Marketing, especially snack and fast-food marketing have taken advantage of these factors with products that mislead the consumer, i.e.; low-fat products that are high in sugar, and low-carb products that are high in fat. (And dont get me started on salt!) (Last moment note: this also ties-in with your observation that _un-healthy_ food is cheaper than healthier alternatives ...

or contaminate them by the slow poisoning of the blood stream. After digestion, everything from fruits and vegetables, to sugars and processed food, find their way into your bloodstream. Your blood acts as fuel to charge cells carrying vital nutrients to each of your organs. The better you nourish these cells, the better they function. Creating balance within this massive operating system is key for overall health and vitality.. The pH scale serves as a measuring stick to how well your body is balanced. Although the scale ranges from 0-14, the human body can only function in a very narrow and slightly alkaline range, from 7.4 to 7.6. If ever your pH falls outside of this range toward acidity, illness occurs. As every food has a caloric value and nutritional content, they also contain an intrinsic ability to be either alkaline-forming or acid-forming. When you consume a lot of acid-forming foods, your body pulls nutrients from other locations to correct the imbalance, causing further nutrient and ...

The first study examined the response to repeated trip perturbations of healthy middle aged adults and vestibulopathy patients, the second examined feedforward adaptation of gait in young, middle aged and older adults to a sustained mechanical perturbation and the third examined the relationship between standing balance and recovery following a tripping perturbation in vestibulopathy patients. The results showed that vestibulopathy is related to a diminished ability to control and recover gait stability after an unexpected perturbation, and to a deficient reactive adaptation potential. With ageing, the ability to recalibrate locomotor commands to control stability is preserved, although this recalibration may ...

Bilateral Vestibulopathy - Current Knowledge and Future Directions to Improve its Diagnosis and Treatment | Frontiers Research...
Bilateral vestibulopathy was recently defined by the Barany society. Unlike in unilateral loss of vestibular function where compensation is typical, many patients with bilateral vestibulopathy experience chronic oscillopsia due to failure of the vestibulo-ocular reflex and gait instability due to failure of vestibulo-spinal reflexes. Other vestibular projections such as those to higher level cognitive processes like spatio-temporal navigation and autonomic reflexes may also be affected and are active areas of investigation. Bilateral vestibulopathy is estimated to affect 21 in 100,000 people and in its most severe forms can have profound impacts on quality of life and lead to increased risk of falls. There are numerous potential contributing factors including aminoglycoside antibiotics like gentamicin, but also genetic causes such as mutations in the COCH gene or syndromes such as neurofibromatosis type 2 or cerebellar ataxia, neuropathy, vestibular areflexia syndrome (CANVAS). Its prevalence may be
Vibration Tests of Full-Scale Earth Dam
Vibration Tests of Full-Scale Earth Dam. Extensive full-scale dynamic tests, including ambient (unique in earth dam research) and forced vibration as well as popper tests were conducted on the Santa Felicia earth dam in Southern California. For the forced vibration tests, the dam was excited into resonance in both the upstream-downstream and longitudinal directions. During the ambient test, the naturally occurring vibrations of the dam were measured. The popper test involved the use of pressure waves originating from a controlled, submerged release of gas. During the tests, three-dimensional measurements of the motions of approximately 25 stations along the crest and seven stations on the downstream slope were recorded and then analyzed in both time and frequency domains. Modes of vibrations and associated natural frequencies as well as damping ratios were determined.
Physio And Health: VESTIBULAR NEURONITIS
There is usually a degree of systemic illness with fever, malaise, myalgia and gastrointestinal upset, suggesting that enteric viruses may be implicated. Vertigo, often with a marked positional element, accompanies the acute illness and may persist for days or several weeks, and sometimes relapses occur. Nystagmus is present in the acute phase, but there is no disturbance of hearing. Caloric tests may show impaired vestibular function on one or both sides ...

Response to symptoms of stroke in the UK: a systematic review | BMC Health Services Research | Full Text
This review demonstrates that from the limited data identified there is a good level of knowledge of the two commonest stroke symptoms and of the need for an emergency response among the general public and at risk patients. There was a tendency for patients and witnesses to contact their general practitioner rather than call for an ambulance. Recognition that the symptoms were due stroke or TIA did not influence time to presentation. Very few studies examined the beliefs and attitudes of the public towards stroke and its treatment, factors that could be important in understanding why people do or do not respond to the symptoms of stroke as an emergency.. Although the public are most likely to recognise unilateral weakness and/or numbness and speech disturbance which are the most common symptoms of stroke, this conclusion is based upon data from 1071 participants in three studies and there are issues around the representativeness of the samples. The majority of the general public regard stroke as ...

Im probably going to review this book (The Paleo Diet, Loren Cordain) when I finish it, and that will include all the negative bits, of which there are a number. However, Ive read enough that Im convinced its an essential book that everyone interested in optimal health ought to read. In spite of the silly (and misguided, in my view) saturated fat-phobia (oops, there I go...), its very valuable in view of understanding ourselves in terms of the vast and varied fossil record, i.e., human evolution in the context of diet (and most notably: how diet drove the evolution), and how utterly-woefully far weve come. A hint: fully 60% of the caloric value in the average American diet (grains, legumes, dairy, refined sugars, vegetable oils and all their derivatives) was not consumed by our primitive ancestors -- AT ALL! Not a bit. Not even one ounce. This is faint recollection (feel free to correct), but when you compare that 60% with what would have been eaten in its place by a primitive ancestor 50,000
