Performance of Fukuda Stepping Test as a function of the severity of caloric weakness in chronic dizzy patients.

BACKGROUND: The purpose of the Fukuda Stepping Test (FST) is to measure asymmetrical vestibulospinal reflex tone resulting from labyrinthine dysfunction. The FST is a low cost evaluation for dizzy patients; however, when compared with gold standard caloric irrigation unilateral weakness (UW) value ≥25%, the FST has not been shown to be a sensitive tool for identifying unilateral vestibular hypofunction. PURPOSE: The purpose of this technical report is to further evaluate the clinical utility of FST with and without headshake as a function of increased caloric asymmetry for individuals with un

Acute onset of dizziness caused by a cavernous malformation lateral to the fourth ventricle: a case report.

Dizziness, diplopia, and nystagmus may be nonspecific symptoms and in part attributed to central causes. We report a case with brain stem lesion and discuss these nonspecific symptoms. A 13-year-old boy presented to our emergency department with a lasting dizziness for 1 week and diplopia for 5 days. New onset horizontal nystagmus was also noted during the physical examination. A cavernous malformation in the right middle cerebral peduncle lateral to the fourth ventricle was suspected by brain computed tomography and confirmed by magnetic resonance imaging. Without progression of the lesion, c…

Postural orthostatic tachycardia syndrome: a case report of palpitations and dizziness following prophylactic mefloquine use.

BACKGROUND: Hirschsprung's disease (HSCR) is a common defect in newborns, and studies have revealed that long non-coding RNA (lncRNA) is involved in the progression of HSCR. This research study aims to investigate the mechanism of downregulated RNA in cancer (DRAIC) on cell proliferation and migration in HSCR. METHODS: Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to detect the expression of DRAIC in HSCR bowel stenosis tissues and normal colon tissues. Cell-counting kit-8 (CCK-8) and Transwell assays were employed to explore whether cellular functions change

Application of multivariate statistics to vestibular testing: discriminating between Menière's disease and migraine associated dizziness.

Menière's disease (MD) and migraine associated dizziness (MAD) are two disorders that can have similar symptomatologies, but differ vastly in treatment. Vestibular testing is sometimes used to help differentiate between these disorders, but the inefficiency of a human interpreter analyzing a multitude of variables independently decreases its utility. Our hypothesis was that we could objectively discriminate between patients with MD and those with MAD using select variables from the vestibular test battery. Sinusoidal harmonic acceleration test variables were reduced to three vestibulo-ocular r…

Static stabilometry, transcranial Doppler, and single photon emission computed tomography in patients with central dizziness.

Previous studies have found that transcranial doppler (TCD) and single photon emission computed tomography (SPECT) are effective means of diagnosing cerebral blood flow disorders in patients with central dizziness whose etiology was unknown by standard audiologic and/or vestibular assessment techniques. Also, static stabilometry, which measures a person's standing center of pressure (COP) movements, has been used to distinguish between patients with central neurologic and peripheral vestibular disorders. The purpose of this retrospective study was to examine the relation between TCD, SPECT, an…
