We report a case of intracerebral haemorrhages associated with continuous spinal analgesia. Continuous spinal analgesia is frequently employed for postoperative analgesia in high-risk patients in our institution. The analgesia is administered via a 20 gauge catheter passed through an 18 gauge Tuohy needle (Portex). A 71-year-old man with severe respiratory impairment had an intrathecal catheter placed for postoperative analgesia. He had a difficult postoperative course, including wound dehiscence, and died from respiratory failure some five weeks postoperatively. On day nine postoperatively he had two tonic-clonic seizures and was subsequently found to have developed bilateral frontal intracerebral haemorrhages. There was no previous history of seizures. Although several confounding variables exist, the most likely explanation for the intracerebral event appears to be an association with the dural puncture and intrathecal catheter Possible mechanisms and risk factors are discussed.

Objective: To identify markers associated with pressure injury (PrI) history in individuals with spinal cord injury (SCI) using two approaches: skin blood flow (SBF) response toward localized heating, and serum marker for insulin resistance.
Methods: For this cross-sectional, observational study of adults with chronic traumatic SCI at T12 and above, researchers recruited two groups of participants: with history of PrI (group 1), and without history of PrI (group 2). The study protocol included obtaining fasting blood samples and measurement of SBF at bilateral heels with localized heating of 42 °C for 30 minutes from all participants.

Significance: Cerebral blood flow (CBF) imaging is crucial for diagnosing cerebrovascular diseases. However, existing large neuroimaging techniques with high cost, low sampling rate, and poor mobility make them unsuitable for continuous and longitudinal CBF monitoring at the bedside.
Aim: We aimed to develop a low-cost, portable, programmable scanning diffuse speckle contrast imaging (PS-DSCI) technology for fast, high-density, and depth-sensitive imaging of CBF in rodents.

Objective: With the global aging population, the incidence of OA is rising annually, and the number of TKA surgeries is rapidly increasing, placing a heavy economic and healthcare burden on society. As one of the key medications in the ERAS protocol, DXM can significantly reduce postoperative pain, suppress nausea and vomiting, and accelerate patient recovery. However, the safety of perioperative DXM use in patients with diabetes remains unclear.

We present an interesting case of a 74-year-old female who presented with spinal accessory neuropathy following an ipsilateral right-sided carotid endarterectomy 6 months after the initial injury. Subsequent surgical exploration revealed a surgical clip that had been placed directly across the spinal accessory nerve. Clip removal and neurolysis was subsequently performed, leaving the nerve intact.

Purpose: We report the use of a pericapsular nerve group (PENG) cryoneurolysis for longer-term analgesia in a patient with a hip fracture and severe medical comorbidities as an alternative to hip fracture surgery.
Clinical Features: A frail but lucid and fully autonomous 97-yr-old female from an assisted living facility sustained a subcapital fracture of her right proximal femur following a ground level fall. She had significant comorbidities including end-stage respiratory disease.
