AI Article Synopsis
- The article examines common conditions related to positional dizziness and discusses methods to differentiate between vestibular and nonvestibular sources of dizziness.
- Recent guidelines support the effectiveness of canalith repositioning maneuvers, like the Epley and Semont maneuvers, for treating posterior canal BPPV, with additional techniques for lateral canal variants.
- Most positional vertigo is caused by peripheral issues and can be treated through simple positioning maneuvers, making it essential for clinicians to recognize the different types of BPPV for effective treatment.
Article Abstract
Purpose: This article reviews the most common conditions that are caused by changes in head or body positions. Practical clinical methods to help distinguish vestibular from nonvestibular and central from peripheral vestibular positional dizziness are discussed. This article also reviews the treatment methods of selected canal variants of benign paroxysmal positional vertigo (BPPV).
Recent Findings: Two recent evidence-based guidelines have established canalith repositioning maneuvers (Epley and Semont maneuvers) as safe and highly effective in the treatment of posterior canal BPPV. Recent studies suggest the Gufoni and the Lempert roll (barbecue) maneuvers are effective in treating lateral canal forms of BPPV.
Summary: Most cases of positional vertigo are of peripheral vestibular origin and can be effectively treated by simple positioning maneuvers. This article reviews the variants of BPPV encountered in clinical practice, including mechanistic cause, differential diagnosis, prognosis, and treatment. Generous use of figures is intended to aid in understanding the most effective treatment maneuver techniques for the more common forms of BPPV. Clinicians who can recognize the types of nystagmus associated with the various canal types of BPPV can usually recognize CNS causes as distinct.

Leveraging Administrative Health Databases to Address Health Challenges in Farming Populations: Scoping Review and Bibliometric Analysis (1975-2024).
JMIR Public Health Surveill
January 2025
Laboratoire AGEIS, Université Grenoble Alpes, La Tronche Cedex, France.
Background: Although agricultural health has gained importance, to date, much of the existing research relies on traditional epidemiological approaches that often face limitations related to sample size, geographic scope, temporal coverage, and the range of health events examined. To address these challenges, a complementary approach involves leveraging and reusing data beyond its original purpose. Administrative health databases (AHDs) are increasingly reused in population-based research and digital public health, especially for populations such as farmers, who face distinct environmental risks.
