UNASSIGNED: Spinal gout, a rare and often underdiagnosed condition, significantly impacts patients\' quality of life. Therefore, the aim of the research is to analyze cases of spinal gout, including clinical features, anatomical location of spinal gout, laboratory studies, imaging studies, treatment choices, and outcomes from various cases of spinal gout.
UNASSIGNED: The author conducted a systematic literature search in the PUBMED and Science Direct databases from 2013 to 2023. We included clinical case presentations of spinal cases in adults, published in English. The three researchers independently reviewed the title and abstract of each article, and any differences in opinions were resolved through consensus. The extracted data were subsequently analyzed descriptively.
UNASSIGNED: A total of 88 cases of spinal gout were obtained and studied. Out of the total reviewed cases of spinal gout, 89.77% of the subjects were male, with an average age of 51.9 years (age range 16-87 years). Common symptoms include back/neck pain (78.41%) and lower extremity weakness (37.50%). The lumbar spine is the most frequently affected region (62.50%), diagnosed primarily through magnetic resonance imaging (MRI) scans. Surgery, performed in 61.36% of cases, commonly involves decompressive laminectomy. Posttreatment, symptoms resolve in 87.50% of cases.
UNASSIGNED: Cases of spinal gout present with a variety of symptoms, including back pain and weakness. Diagnosis typically involves an MRI examination and synovial fluid analysis for confirmation. Treatment varies and includes medication therapy and surgical interventions. A deeper understanding of these cases can assist healthcare practitioners in the management and diagnosis of spinal gout cases.

Stegosaurs are a minor but iconic clade of ornithischian dinosaurs, yet due to a poor fossil record, their early evolution is poorly understood. Here, we describe a new stegosaur, Baiyinosaurus baojiensis, gen. et sp. nov. from the Middle Jurassic Wangjiashan Formation of the Pingchuan District, Baiyin City, Gansu Province, China. The frontal of Baiyinosaurus possesses a unique characteristic among Stegosauria: it is wider than long and contributes to both the medial and anterior margins of the supratemporal fenestra. The character combinations of dorsal vertebrae of Baiyinosaurus are also different to other stegosaurs: its neural arches are not greatly elongated, its parapophyses are well developed, and its neural spines are axially expanded in lateral. The features of the frontal and vertebrae of Baiyinosaurus are reminiscent of basally branching thyreophorans, indicating that Baiyinosaurus is transitional in morphology between early thyreophorans and early-diverging stegosaurs. Systematic analysis shows that Baiyinosaurus is an early-diverging stegosaur.

Postural sway has not been investigated before or after a neck exercise intervention in individuals with chronic whiplash-associated disorders (WAD). The aim of the study was to investigate postural sway in individuals with chronic WAD grades 2 and 3: (a) compared with healthy matched controls at baseline; (b) after three months of neck-specific exercise and (c) to investigate the correlation between postural sway with self-reported dizziness during motion and balance problems/unsteadiness. This is a longitudinal prospective experimental case-control intervention study. Individuals with WAD (n = 30) and age- and gender-matched healthy volunteers (n = 30) participated. Postural sway was assessed using an iPhone application. Measurements were carried out at baseline, and for those with WAD a second measurement was performed at the three-month follow-up when neck-specific exercise intervention ended. The WAD group performed significantly worse than the healthy group in both pathway and ellipse area double stance eyes closed at baseline (main outcome), but not at the three-month follow-up. The WAD group significantly improved after rehabilitation in both pathway double stance eyes closed and pathway single stance eyes open. The correlation between postural sway and self-rated dizziness during motion and balance problems was low to moderate. One may conclude that postural sway was improved after a neck-specific exercise programme. The study results strengthen earlier findings that individuals with WAD have worse balance outcome when they have to rely on neck proprioception (eyes closed). The study results may be important for the development of improved rehabilitation methods for WAD.

Artificial intelligence (AI) is transforming spinal imaging and patient care through automated analysis and enhanced decision-making. This review presents a clinical task-based evaluation, highlighting the specific impact of AI techniques on different aspects of spinal imaging and patient care. We first discuss how AI can potentially improve image quality through techniques like denoising or artifact reduction. We then explore how AI enables efficient quantification of anatomical measurements, spinal curvature parameters, vertebral segmentation, and disc grading. This facilitates objective, accurate interpretation and diagnosis. AI models now reliably detect key spinal pathologies, achieving expert-level performance in tasks like identifying fractures, stenosis, infections, and tumors. Beyond diagnosis, AI also assists surgical planning via synthetic computed tomography generation, augmented reality systems, and robotic guidance. Furthermore, AI image analysis combined with clinical data enables personalized predictions to guide treatment decisions, such as forecasting spine surgery outcomes. However, challenges still need to be addressed in implementing AI clinically, including model interpretability, generalizability, and data limitations. Multicenter collaboration using large, diverse datasets is critical to advance the field further. While adoption barriers persist, AI presents a transformative opportunity to revolutionize spinal imaging workflows, empowering clinicians to translate data into actionable insights for improved patient care.

OBJECTIVE: This study aimed to examine the effects of a remote video-based cervical stabilization exercise program on cervical proprioception, functional status, and disease-related quality of life in patients with rheumatoid arthritis (RA).
METHODS: Patients with RA were evaluated regarding cervical joint positioning error, cervical region functional status (Neck Disability Index), general functional status (Health Assessment Questionnaire), and disease-related quality of life (Rheumatoid Arthritis Quality of Life Scale). Patients were randomized to exercise (n = 14, 10 female) and control (n = 12, 9 female) groups. Patients in the exercise group performed a video-based home exercise program consisting of progressive cervical stabilization exercises three times a week for six weeks in addition to their routine medication. The patients in the control group continued their routine medication only. Evaluations were repeated in both groups in the seventh week following the baseline evaluation.
RESULTS: Groups were similar at baseline (p > 0.05). Patients in both groups had low disease activity (DAS-28 CRP ≤ 3.2). The remote video-based exercise program led to significant improvements in cervical proprioception, functional status, and disease-related quality of life (p < 0.05). No significant changes were detected in any parameters in the control group (p > 0.05). Obtained changes were superior in the exercise group compared to the control group (d > 1.00, p < 0.05).
CONCLUSIONS: Cervical stabilization exercises may increase cervical proprioception, improve functional status, and enhance disease-related quality of life in patients with RA when administered as a remote program.

UNASSIGNED: ZIEL: Ziel dieser Studie war es, die Auswirkungen eines ferngesteuerten videobasierten Übungsprogramms zur Stabilisierung der Halswirbelsäule auf die zervikale Propriozeption, den Funktionsstatus und die krankheitsbezogene Lebensqualität von Patienten mit rheumatoider Arthritis (RA) zu untersuchen.
METHODS: Patienten mit RA wurden hinsichtlich der Fehlstellung des Halsgelenks, des Funktionsstatus der Halswirbelsäule (Neck Disability Index), des allgemeinen Funktionsstatus (Health Assessment Questionnaire) und der krankheitsbezogenen Lebensqualität (Rheumatoid Arthritis Quality of Life Scale) zu Baseline untersucht. Anschließend wurden sie randomisiert einer Interventions- (n = 14, 10 Frauen) und einer Kontrollgruppe (n = 12, 9 Frauen) zugeteilt. Patienten der Interventionsgruppe führten ein häusliches, videobasiertes Trainingsprogramm durch, das aus progressiven Übungen zur Stabilisierung der Halswirbelsäule bestand. Dies erfolgte dreimal wöchentlich über einen Zeitraum von sechs Wochen. Patienten beider Gruppen erhielten in diesem Zeitraum ihre medikamentöse Routineversorgung. Die Messungen zum Interventionsende erfolgten analog zur Eingangsuntersuchung vor Interventionsbeginn.
UNASSIGNED: Die Gruppen waren zu Studienbeginn vergleichbar (p > 0,05). Patienten beider Gruppen hatten eine geringe Krankheitsaktivität (DAS-28 CRP ≤ 3,2). Das videobasierte Übungsprogramm führte zu signifikanten Verbesserungen der zervikalen Propriozeption, des funktionellen Status und der krankheitsbezogenen Lebensqualität (p < 0,05). In der Kontrollgruppe wurden hingegen keine signifikanten Veränderungen hinsichtlich der untersuchten Parameter festgestellt (p > 0,05). Die erzielten Veränderungen waren in der Interventionsgruppe besser als in der Kontrollgruppe (d > 1,00, p < 0,05).
UNASSIGNED: Ein videogestütztes Heimtrainingsprogramm zur Stabilisierung der Halswirbelsäule kann bei Patienten mit RA die zervikale Propriozeption, den Funktionsstatus sowie die krankheitsbezogene Lebensqualität verbessern.

Spinal dural arteriovenous fistula (AVF) is an abnormal shunting between the segmental artery and radicular vein adjacent to the dural root sleeve in the spine. This is the most common vascular malformation of the spinal cord and is a rare but treatable cause of para or quadriplegia. It most commonly occurs in elderly men and often affects the thoracolumbar region. These patients clinically present with progressive myelopathies, and other autonomic symptoms (e.g., bladder and bowel dysfunction) subsequently in the later course of the disease. Computed tomography angiography and magnetic resonance imaging remain the modality for initial evaluation. Herein, we present a rare case of spinal dural AVF in a child along with a review of imaging modalities. To the best of our knowledge, there are few case reports of this condition in a paediatric age group.

Spinal magnetic resonance (MR) scans are a vital tool for diagnosing the cause of back pain for many diseases and conditions. However, interpreting clinically useful information from these scans can be challenging, time-consuming and hard to reproduce across different radiologists. In this paper, we alleviate these problems by introducing a multi-stage automated pipeline for analysing spinal MR scans. This pipeline first detects and labels vertebral bodies across several commonly used sequences (e.g. T1w, T2w and STIR) and fields of view (e.g. lumbar, cervical, whole spine). Using these detections it then performs automated diagnosis for several spinal disorders, including intervertebral disc degenerative changes in T1w and T2w lumbar scans, and spinal metastases, cord compression and vertebral fractures. To achieve this, we propose a new method of vertebrae detection and labelling, using vector fields to group together detected vertebral landmarks and a language-modelling inspired beam search to determine the corresponding levels of the detections. We also employ a new transformer-based architecture to perform radiological grading which incorporates context from multiple vertebrae and sequences, as a real radiologist would. The performance of each stage of the pipeline is tested in isolation on several clinical datasets, each consisting of 66 to 421 scans. The outputs are compared to manual annotations of expert radiologists, demonstrating accurate vertebrae detection across a range of scan parameters. Similarly, the model\'s grading predictions for various types of disc degeneration and detection of spinal metastases closely match those of an expert radiologist. To aid future research, our code and trained models are made publicly available.

UNASSIGNED: Cystic schwannomas have only been reported in a few case reports/series. As a result, they may be misdiagnosed and a standardized management approach remains challenging to establish.
UNASSIGNED: The aim of this study was to compile all reported cases of cystic schwannomas and analyze the perioperative course based on a systematic review of the literature with an additional two cases from the authors\' experience.
UNASSIGNED: We conducted a search of MEDLINE and CENTRAL databases for spinal intradural extramedullary cystic schwannomas, in accordance to the PRISMA statement. All title/abstracts were screened, and a full-text review of the remaining articles was conducted. The results were compiled in tables and summarized using means and standard deviation (SD), median and interquartile range, and percentage and 95% confidence intervals.
UNASSIGNED: We identified 263 articles, of which 35, which reported 54 cases, were included. Including our case-reports (n = 56), patients had a mean age of 47.7 years (SD ± 13.0 years) at presentation, 57% were males, and most lesions were lumbar (43%). The most common symptoms were pain (82%) and muscle weakness (68%) with 84% of patients showing neurological findings. 70% of patients showed a complete relief of symptoms after surgery and 96% reported improvement. Only four complications were reported.
UNASSIGNED: Schwannomas should be considered in the differential diagnosis of intradural extramedullary cystic lesions. Patients typically present with subacute to chronic pain and/or neurologic changes. Surgical resection is the primary therapeutic modality and usually has a good to excellent outcome.

UNASSIGNED: Low back pain (LBP) is the most frequent indication to magnetic resonance imaging (MRI) examinations of the lumbosacral spine. The individual role of soft tissues, including muscles, on LBP is not fully understood and the contribution of each MRI-derived parameter of soft tissues status on the intensity of LBP has not been investigated in detail.
UNASSIGNED: The study design was observational retrospective, single center carried out at a University Hospital. Images were acquired using a using a 1.5 Tesla scanner. Patients completed a symptom questionnaire and rated their pain intensity using the Visual Analogue Scale (VAS). The VAS scores ​​were categorized as mild, moderate, and severe using cutoff values of 3.8 and 5.7, based on the literature. Biometric data, including weight and height, were also recorded to calculate the body mass index (BMI). The ratios between intramuscular fat infiltration and net muscle area were also calculated. Patient sample included 94 patients with LBP underwent MRI of the lumbosacral spine.
UNASSIGNED: The stepwise analysis revealed that increasing psoas net area was associated with lower VAS levels (odds ratio [OR]: 0.94: 95% confidence interval [CI]: 0.90-0.98; p=.005), and an increase of one square centimeter of total psoas area resulted in a greater probability of reporting a mild (+1.21%; 95% CI: 0.37, 2.05%) or a moderate VAS (+0.40%; 95% CI: -0.02, 0.82%), Furthermore, a more severe VAS was associated with a higher BMI (OR: 1.13; 95% CI: 1.00-1.27).
UNASSIGNED: Our study demonstrates a relationship between LBP and MRI parameters of paravertebral and psoas muscles status. The psoas muscle is extremely important for spine stabilization and is linked to clinical symptoms of patients affected by LBP. These findings could contribute to future studies and improve treatment options in patients with LBP, possibly reducing the impact on disability, quality of life and socioeconomical burden.

Microglia continuously remodel synapses, which are embedded in the extracellular matrix (ECM). However, the mechanisms, which govern this process remain elusive. To investigate the influence of the neural ECM in synaptic remodeling by microglia, we disrupted ECM integrity by injection of chondroitinase ABC (ChABC) into the retrosplenial cortex of healthy adult mice. Using in vivo two-photon microscopy we found that ChABC treatment increased microglial branching complexity and ECM phagocytic capacity and decreased spine elimination rate under basal conditions. Moreover, ECM attenuation largely prevented synaptic remodeling following synaptic stress induced by photodamage of single synaptic elements. These changes were associated with less stable and smaller microglial contacts at the synaptic damage sites, diminished deposition of calreticulin and complement proteins C1q and C3 at synapses and impaired expression of microglial CR3 receptor. Thus, our findings provide novel insights into the function of the neural ECM in deposition of complement proteins and synaptic remodeling by microglia.
