Reduced Vestibular Function is Associated with Cortical Surface Shape Changes in the Frontal Cortex.

Aging-associated decline in peripheral vestibular function is linked to deficits in executive ability, self-motion perception, and motor planning and execution. While these behaviors are known to rely on the sensorimotor and frontal cortices, the precise pathways involving the frontal and sensorimotor cortices in these vestibular-associated behaviors are unknown. To fill this knowledge gap, this cross-sectional study investigates the relationship between age-related variation in vestibular function and surface shape alterations of the frontal and sensorimotor cortices, considering age, intracranial volume, and sex.

Automatic Segmentation of Heschl Gyrus and Planum Temporale by MRICloud.

Objectives: This study used a cloud-based program, MRICloud, which parcellates T1 MRI brain scans using a probabilistic classification based on manually labeled multi-atlas, to create a tool to segment Heschl gyrus (HG) and the planum temporale (PT).

Methods: MRICloud is an online platform that can automatically segment structural MRIs into 287 labeled brain regions. A 31-brain multi-atlas was manually resegmented to include tags for the HG and PT.

Late Relapse in Genetically Determined Infantile Myofibromatosis. A Case Report and Brief Focus on Recurrences.

Background: Infantile myofibromatosis (IM) is a rare disorder characterized by benign tumors in the skin, subcutaneous tissue, muscle, and occasionally viscera. IM can be hereditary due to PDGFRB or NOTCH3 variants. Treatment is mainly conservative or surgical.

Local spatial navigation or "steering" in patients with vestibular loss in a virtual reality environment.

Background: Patients with vestibular loss have reduced wayfinding ability, but the association between vestibular loss and impaired steering spatial navigation is unclear.

Objective: To evaluate whether vestibular loss is associated with reduced steering navigation performance in a virtual reality (VR) environment containing obstacles.

Methods: 17 ambulatory adults with vestibular loss were age/sex-matched to healthy controls.

PENG block associated with dexmedetomidine sedation for intramedullary femoral fixation in high-risk elderly patients: a case series and review of the literature.

Background: Hip fracture is a major cause of hospitalization among the elderly population. The standard surgical treatment involves early repair to reduce mortality and morbidity. One type of treatment in the case of intertrochanteric and subtrochanteric fractures is intramedullary nailing, as it decreases soft tissue damage and permits early weight bearing.
