ReviewIntracranial hematoma and abscess after neuraxial analgesia and anesthesia: a review of the literature describing 297 cases.
Besides spinal complications, intracranial hematoma or abscess may occur after neuraxial block. Risk factors and outcome remain unclear. ⋯ Diagnosis of intracranial hematoma is often missed initially, as headache is assumed to be caused by cerebrospinal hypotension due to cerebrospinal fluid leakage, known as PDPH. Prolonged headache without improvement, worsening symptoms despite treatment or epidural blood patch, change of headache from postural to non-postural or new neurological signs should alert physicians to alternative diagnoses.

Review Meta AnalysisPrevalence of chronic pain after spinal cord injury: a systematic review and meta-analysis.
The reported prevalence of chronic pain after spinal cord injury (SCI) varies widely due, in part, to differences in the taxonomy of chronic pain. A widely used classification system is available to describe subcategories of chronic pain in SCI, but the prevalence of chronic pain in SCI based on this system is unknown. ⋯ This systematic review and meta-analysis extends the findings of previous studies by reporting the prevalence of chronic pain after SCI based on the ISCIP classification system, thereby reducing clinical heterogeneity in the reporting of pain prevalence related to SCI.

ReviewRegional anesthesia for scapular fracture surgery: an educational review of anatomy and techniques.
Scapular fractures are very rare, and those requiring surgical interventions are even rarer. Most scapula surgeries are done under general anesthesia with or without the regional anesthesia (RA) technique as an adjunct. ⋯ In this review, we are describing an algorithmic "identify-select-combine" approach, which enables the anesthesiologist to understand detailed innervation of the scapula and to obtain a procedure-specific RA technique. Procedure-specific RA would probably be the way forward for defining future RA practices.

ReviewDifferences in calculated percentage improvement versus patient-reported percentage improvement in pain scores: a review of spinal cord stimulation trials.
Spinal cord stimulation is frequently used for the treatment of intractable chronic pain conditions. Trialing of the spinal cord stimulator device is recommended to assess the patient's response to neurostimulation before permanent implantation. The trial response is often assessed by Numeric Rating Scale changes and patient-reported percentage pain improvement. Using number rating scale changes between prespinal and postspinal cord stimulation trial, a calculated percentage pain improvement can be obtained. The aim of this study was to assess the difference between calculated and patient-reported percentage improvement in pain scale during spinal cord stimulation trials. ⋯ Although the two methods are highly correlated, there is substantial lack of agreement between patient-reported and calculated percentage improvement in pain scale, suggesting that these measures should not be used interchangeably for spinal cord stimulator trial outcome assessment. This emphasizes the need for improved metrics to better measure patient response to neuromodulation therapies. Additionally, patient-reported percentage improvement in pain was found to be higher than calculated percentage improvement in pain, potentially highlighting the multidimensional experience of pain and the unpredictability of solely using Numeric Rating Scale scores to assess patient outcomes.
