Article Abstract
Background: Up to 60% of Parkinson's disease (PD) patients suffer from low back pain (LBP) during the course of their disease. How LBP affects daily functional status and how to manage this aspect of PD has not been adequately explored.
Methods: We examined 16 patients undergoing bilateral subthalamic nucleus deep brain stimulation (STN DBS) who met the inclusion criteria for moderate disability from LBP, as classified by the Oswestry Low Back Pain Disability Index (OLBPD).
Results: Thirteen of 16 patients had attempted additional treatments for LBP, including medical management, massage, chiropractic, epidural steroid injections and/or surgery, with minimal relief. Following DBS, there was a significant improvement in the OLBPD at both the 6-month and 1-year time points (p < 0.02, p < 0.005, respectively). A mean improvement of 31.7% on the OLBPD score was noted. The Visual Analogue Scale (VAS) similarly decreased significantly at 1 year (p = 0.015). There was no correlation between the OLBPD score and other measures, including the Unified Parkinson's Disease Rating Scale (UPDRS), age and other nonmotor symptoms.
Conclusion: Given the prevalent yet undertreated disability associated with LBP in PD, these results are novel in that they show that STN DBS has a significant positive effect on disability associated with LBP.

Photobiomodulation (PBM) therapy involves the use of low-dose, nonionizing light to reduce pain and inflammation, promote wound healing, and enhance tissue regeneration. PBM-based therapy of various dental conditions is associated with improved treatment outcomes. This study aims to critically review the literature to highlight the underlying molecular biological mechanisms and clinical applications of PBM in modern dental practice.

Atypical proximal tibial fractures in adolescents are rare, particularly when linked to hormonal therapy for short stature. This case series reports the clinical and imaging features of atypical proximal tibial and distal femoral physeal fractures in male adolescents undergoing combined growth hormone (GH) and aromatase inhibitor (AI) therapy for idiopathic short stature. We report three cases of skeletally immature male adolescents (ages 12-16) treated with GH and anastrozole who presented with acute leg pain following low-energy trauma during soccer.

Objectives: This study aims to describe the cone-beam computed tomography (CBCT) characteristics of external root resorption (ERR) in second molars associated with impacted third molars.
Methods: This study analyzed 69 s molars diagnosed with ERR caused by impacted third molars in 52 patients (age range: 22-59 years; mean age = 31.2 ± 7.

Objective: The purpose of this study was to compare the effects of 16 weeks of functional versus dual-task training on aspects of pain in older women with chronic nonspecific low back pain.
Methods: This randomized clinical trial included 38 participants aged 60 to 79 years divided into 2 groups: functional training (FT) and dual-task training (DT). We assessed pressure pain threshold (PPT), temporal summation of pain, conditioned pain modulation (CPM), trunk instability, isometric strength, and endurance of trunk muscles before and 16 weeks after training.
