The aim of this study was to assess the prevalence and analyze clinical parameters of benign positional paroxysmal vertigo (BPPV) in a pediatric age. A cohort of 423 children under the age of 15 (median age 11. interquartile range 9–13) was submitted to vestibular assessment for balance disorders. Dix-Hallpike and Roll-Supine tests were performed to look for positioning nystagmus using video-infrared goggles. BPPV was found in 43 of 423 children evaluated for balance disorders (10.2%). There were 28 females (65.1%) and 15 (34.9%) males. The posterior canal was involved in 79% of cases and the horizontal canal in 21% of cases. No apogeotropic bilateral or anterior canal form were seen. Thus, BPPV is not an infrequent type of vertigo in children and must be evaluated as soon as possible in order to plan the most appropriate maneuver and restore daily activities as soon as possible, avoiding anxiety and fear.

Balance Disorder

AbstractVasopressin-mediated water reabsorption from primary urine in the renal collecting duct is essential for regulating body water homeostasis and depends on the water channel aquaporin-2 (AQP2).Dysregulation of the process can cause water balance disorders. Here, we present cell-based high-throughput screenings to identify proteins and small molecules as tools to elucidate molecular mechanisms underlying the AQP2 control and as potential starting points for the development of water balance disorder drugs.

Dynamic posturography comprises a series of balance control tests which help physicians overcome numerous diagnostic and treatment challenges arising when examining patients complaining of a debilitating balance disorder. These challenges include the specific differential diagnosis, documentation of symptoms and assessment of functional disability. It must be determined whether the cause of the disability is an organic sensory deficit, a central nervous system (CNS) lesion or a non-organic (that is, possibly psychogenic or just overtly simulated) disorder. This review is targeted towards providing the reader (a) an overview of the effects sensori-motor deficits have on balance control, specifically vestibulo-spinal and proprioceptive reflex deficits; and, (b) how these effects may be assessed objectively in a clinical setting to differentiate between various organic and non-organic balance-disorders. The techniques used to study these effects are based on the analysis of both rapid balance-correcting and slow balance-stabilizing responses to fast and slow movements in the pitch plane of the support surface on which the test subject stands.
