Preventing subsequent fractures after vertebral augmentation is a critical clinical concern. The purpose of this study was to compare the effect of romosozumab and bisphosphonate administration on the occurrence of subsequent vertebral fractures after balloon kyphoplasty (BKP) and to identify factors associated with the occurrence of subsequent vertebral fractures. The study compared 24 patients who underwent BKP and received romosozumab with 58 control patients who underwent BKP and received bisphosphonates, all within 2 months of acute osteoporotic vertebral fracture and showing unfavorable magnetic resonance imaging prognostic factors.

Introduction: Balloon kyphoplasty (BKP) for osteoporotic vertebral fracture (OVF) has been reported to maintain quality of life (QOL). This study aimed to investigate the effectiveness of ultra-early BKP performed within two weeks of injury (ultra-early group) to cases after two to four weeks post-injury (early group) and over four weeks (conventional group), assessing radiographic assessment such as subsequent fracture etc, questionarre such as QOL and back pain-related activities of daily living (ADL) one year after surgery.
Methods: Ninety cases of OVF treated with BKP (23 males, 67 females, average age 78.

Study Design: Retrospective cohort study.
Purpose: Balloon kyphoplasty (BKP) is a minimally invasive surgical treatment for osteoporotic vertebral compression fractures (OVCFs), with good clinical outcomes reported in short-term investigations. However, the impact of BKP on health-related QOL in the long term remains unclear.

Background: Despite the burden of low back pain (LBP) there is no currently accepted definition for its recovery, nor is there a gold standard for measurement. In addition, it is currently unclear how the perspective of patients are used in making recovery determinations. The purpose of this mixed study systematic review across both quantitative and qualitative literature was to (1) explore how recovery has been defined and measured for patients experiencing LBP, and (2) examine how the perspectives of patients and providers for recovery of LBP align or differ.

Introduction: Postoperative spinal epidural hematoma (PSEH) is a severe complication of spinal surgery that necessitates accurate and timely diagnosis. This study aimed to assess the accuracy of ultrasonography as an alternative diagnostic tool for PSEH after microendoscopic laminotomy (MEL) for lumbar spinal stenosis, comparing it with magnetic resonance imaging (MRI).
Methods: A total of 65 patients who underwent MEL were evaluated using both ultrasound- and MRI-based classifications for PSEH.

Transmission is the first step for a microorganism to establish colonization in the respiratory tract and subsequent development of infectious disease. is a leading pathogen that colonizes the mucosal surfaces of the human upper respiratory tract and causes subsequent transmission and invasive infections especially in co-infection with influenza A virus. Host factors contributing to respiratory contagion are poorly understood.

Purpose: Effect of topical administration of a Rho kinase inhibitor, ripasudil, on epithelial wound healing in a mouse cornea was investigated. Effects of treatment of cultured human corneal epithelial cell (HCEC) line and organ-cultured corneal epithelium with ripasudil on expression of p-ERK was also examined.
Methods: Epithelial defects with a diameter of 2.

Objective: In this study, the authors aimed to determine the mid- to long-term outcomes of microendoscopic laminotomy (MEL) for lumbar spinal stenosis (LSS) with degenerative spondylolisthesis (DS) and identify preoperative predictors of poor mid- to long-term outcomes.
Methods: The authors retrospectively reviewed the medical records of 274 patients who underwent spinal MEL for symptomatic LSS. The minimum postoperative follow-up duration was 5 years.

Study Design: Secondary analysis of a randomized controlled trial.
Objective: We investigated the ability to distinguish patients with lumbar spinal stenosis (LSS) who improved from those who did not after receiving nonsurgical treatment. We used the disorder-specific Zurich Claudication Questionnaire (ZCQ) satisfaction subscale as an external anchor and estimated the minimal clinically important differences (MCIDs) for the ZCQ symptom severity and physical function subscales.

In our previous study, istradefylline treatment in patients with Parkinson's disease (PD) improved postural abnormalities (PAs), as seen from a decrease in the mean Unified Dystonia Rating Scale (UDRS) total score from week 0 to week 24. A subgroup analysis based on baseline clinical characteristics investigated the association between improvement in the UDRS total score and istradefylline treatment. However, the association between an objective assessment of PAs and improvement in the UDRS total score is unclear.

Objective: The objective of this study was to determine the long-term outcomes of microendoscopic foraminotomy in treating lumbar foraminal stenosis and identify the optimal extent of decompression that yields improved results and fewer complications.
Methods: A retrospective cohort study reviewed the medical records of 95 consecutive patients who underwent microendoscopic foraminotomy for lumbar foraminal stenosis. Clinical outcomes were assessed using the Japanese Orthopaedic Association scoring system and visual analog scale for low back and leg pain.

We examined the effects of gene ablation and chemical inhibition of transient receptor potential ankyrin 1 (TRPA1) on the growth of experimental argon laser-induced choroidal neovascularization (CNV) in mice. CNV was induced in the eyes of 6- to 8-week-old TRPA1-null (knockout [KO]) and wild-type (WT) mice by argon laser irradiation. Gene expression analysis was performed in laser-injured tissues at days 1 and 3.

We present varicella-zoster virus (VZV) infection with concomitant lower cranial polyneuropathy in the absence of meningeal symptoms. Physical examination showed involvement of cranial nerves IX and X in Case 1 and of cranial nerves IX, X, and XI in Case 2. Cerebrospinal fluid (CSF) analysis revealed mild lymphocytic pleocytosis, normal protein levels, and absence of VZV-DNA based on polymerase chain reaction (PCR) analysis.
