Article Abstract

Objective: This study aimed to investigate whether the anatomical location of the globus sensation influences treatment outcome in patients with globus pharyngeus.

Methods: A prospective cohort study was conducted between March 2023 and May 2024 with 55 patients who presented with globus sensation. The participants were categorized into the upper and lower globus groups based on the anatomical location of globus sensation relative to the upper esophageal sphincter. All patients received proton pump inhibitor (PPI) therapy for up to 12 weeks, and treatment response was assessed using the Reflux Symptom Index (RSI) and Reflux Finding Score (RFS). Log-rank tests and logistic regression analysis were performed to identify the factors associated with treatment response.

Results: Patients with upper globus showed a significantly-higher rate of symptom improvement (78.6%) than those with lower globus (40.7%). Symptom severity (measured by the RSI) was higher in the lower globus group, while posterior commissure hypertrophy (measured by the RFS) was more prevalent in the upper globus group. Factors positively associated with symptom improvement included the location of the upper globus and coffee cessation. The lower globus group showed resistance to PPI therapy.

Conclusion: Patients with upper globus respond better to PPI therapy, whereas those with lower globus do not. The anatomical location of the globus sensation may affect treatment outcomes.

Iron-the most abundant magnetic brain substance-is essential for many biological processes, including dopamine and myelin synthesis. Quantitative susceptibility mapping (QSM) MRI has recently linked altered subcortical magnetic susceptibility (χ) to schizophrenia. Since χ is increased by iron and decreased by myelin, abnormal levels of either could underlie these QSM differences.

Background: Excessive exposure to manganese (Mn) causes parkinsonism. Occupational Mn exposure is associated with increased T1-weighted globus pallidus signal on magnetic resonance imaging (MRI) secondary to in-vivo Mn deposition.

Methods: The present study evaluated the T1-weighted pallidal index (PI) as an in-vivo marker of Mn exposure and neurotoxicity in chronic environmental Mn exposure.

Study Design: Retrospective Cohort.

Summary Of Background Data: Spinal fusions are common interventions for degenerative spine disease (DSD), with increasing utilization in obese and metabolic syndrome populations. Glucagon-like peptide-1 (GLP-1) receptor agonists (RA), widely adopted for diabetes and weight management, may offer systemic benefits that exert a parallel influence on surgical outcomes.

Purpose: To biomechanically assess the influence of intraoperative correction and presenting Sanders maturity scores (SS) on growth modulation correction after 2 years in pediatric idiopathic scoliosis treated with Vertebral Body Tethering (VBT).

Methods: Lumbar VBT was simulated using patient-specific finite element models (FEMs) from 20 cases of pediatric idiopathic scoliosis (average thoracolumbar/lumbar Cobb 47°; min: 34°, max: 63°), calibrated for preoperative SS, weight, and spine flexibility. The validated FEM included lateral decubitus positioning and VBT instrumentation at the actual upper instrumented vertebra (UIV: T9-T12) and lower instrumented vertebra (LIV: L2-L4).

Background: Multiligament knee injuries (MLKIs) often result from high-energy trauma in polytrauma patients. They may coincide with other musculoskeletal injuries, especially fractures of the ipsilateral lower extremity (LE) or pelvis. Understanding these fracture patterns can guide surgical planning and improve patient outcomes.
