Background: Spontaneous spinal epidural hematoma is a rare but disabling disease. To explore its characters and find out what factors influence the prognosis, we gave a retrospective analysis of 23 patients in our department in the past 8 years.
Methods: Spontaneous spinal epidural hematoma was diagnosed by taking MRIs of patients without surgical management or by histopathological examination. We registered patient's case history, laboratory examination, radiological image, treatment, pathological result, and prognosis after 3 months and gave them nonparameter analysis.
Results: Primary neurological status and progressive intervals have correlation with prognosis (P< .01), and the latter less than 12 hours predict worse prognosis (P= .032). Spinal edema in MRI predicts pessimistic prognosis (P= .013). Long hematoma predicts worse prognosis (P= .02). Preoperative interval, emphasized by other authors, has no statistical correlation with prognosis in this study (P= .832). Finally, patients with a single hematoma or hematoma mingled with other spinal disturbance have the same prognosis (P= .065).
Conclusions: The primary neurological status, progressive interval, spinal edema, and size of hematoma will influence the prognosis of the patient with SSEH. The major treatment is surgical intervention, and it should be operated as soon as possible to avoid the aggravation of neurological status. Conservative treatment is not considered unless patient's neurological deficiency has relieved in the early period.

Advanced Imaging of Type 2 Spinal CSF Leaks with Ultrahigh-Resolution Cone-Beam CT Myelography.

From Department of Neuroradiology (Niklas Lützen, Charlotte Zander, Horst Urbach), Medical Center - University of Freiburg, Faculty of Medicine, University of Freiburg, Germany and Department of Neurosurgery (Jürgen Beck, Florian Volz, Katharina Wolf, Amir El Rahal), Medical Center - University of Freiburg, Faculty of Medicine, University of Freiburg, Germany.
Type 2 CSF leaks are spinal lateral dural tears, causing spontaneous intracranial hypotension (SIH). They may be visualized with digital subtraction myelography (DSM), cone-beam CT (CBCT) myelography, energy-integrating detector or photon-counting CT myelography. A recently introduced ultrahigh-resolution cone-beam CT (UHR-CBCT) myelography has shown beneficial visualization of CSF-venous fistula, another cause of SIH.

Spondyloarthritis is a prevalent and persistent condition that significantly impacts the quality of life. Its intricate pathological mechanisms have led to a scarcity of animal models capable of replicating the disease progression in humans, making it a prominent area of research interest in the field. To delve into the pathological and physiological traits of spontaneous non-human primate spondyloarthritis, this study meticulously examined the disease features of this natural disease model through an array of techniques including X-ray imaging, MRI imaging, blood biochemistry, markers of bone metabolism, transcriptomics, proteomics, and metabolomics.

Volumetric response after closure of a spinal CSF leak in patients with spontaneous intracranial hypotension: a multicompartmental longitudinal study.

Department of Neuroradiology, Medical Center - University of Freiburg, Freiburg, Germany
Background: Cerebrospinal fluid (CSF) loss in spontaneous intracranial hypotension (SIH) is accompanied by volume shifts between the intracranial compartments. This study investigated tricompartimental and longitudinal volume shifts after closure of a CSF leak.
Methods: Patients with SIH and suitable pre-therapeutic and post-therapeutic imaging for volumetric analysis were identified from our tertiary care center between 2020 and 2023.
An optogenetic mouse model of hindlimb spasticity after spinal cord injury.

Brain and Mind Research Institute, Department of Biology, University of Ottawa, Ottawa, Ontario, Canada. Electronic address:
Spasticity is a common comorbidity of spinal cord injury (SCI), disrupting motor function and resulting in significant discomfort. While elements of post-SCI spasticity can be assessed using pre-clinical SCI models, the robust measurement of spasticity severity can be difficult due to its periodic and spontaneous appearance. Electrical stimulation of sensory afferents can elicit spasticity-associated motor responses, such as spasms; however, placing surface electrodes on the hindlimbs of awake animals can induce stress or encumbrance that could influence the expression of behaviour.
