Diagnosis and treatment of the short-arm type posterior semicircular canal BPPV.

Introduction: The Epley maneuver is useful for the otoconia to return from the long arm of the posterior semicircular canal into the utricle. To move otoconia out of the posterior semicircular canal short arm and into the utricle, we need different maneuvers.

Objective: To diagnose the short-arm type BPPV of the posterior semicircular canal and treat them with bow-and-yaw maneuver.

Theoretical observation on diagnosis maneuver for benign paroxysmal positional vertigo.

Conclusion: To make a comprehensive analysis with a variety of diagnostic maneuvers is conducive to the correct diagnosis and classification of BPPV.

Objective: Based on the standard spatial coordinate-based semicircular canal model for theoretical observation on diagnostic maneuvers for benign paroxysmal positional vertigo (BPPV) to analyze the meaning and key point of each step of the maneuver.

Materials And Methods: This study started by building a standard model of semicircular canal with space orientation by segmentation of the inner ear done with the 3D Slicer software based on MRI scans, then gives a demonstration and observation of BPPV diagnostic maneuvers by using the model.

Serum S100B levels may be associated with cerebral infarction: a meta-analysis.

Objective: The aim of this paper is to explore the potential association of serum human soluble protein-100B protein (S100B) levels with the diagnosis and prognosis of cerebral infarction (CI).

Methods: Potential relevant studies were searched for in PubMed, Springerlink, Wiley, EBSCO, Ovid, Web of Science, Wanfang databases, China National Knowledge Infrastructure (CNKI) databases and VIP databases. Two investigators extracted data and assessed studies independently.
