We aimed to compare outcomes of early and standard closure of diverting loop ileostomy (DLI) after proctectomy and determine risk factors for anastomotic leak (AL) and complications. ⋯ Early closure of DLI after proctectomy has a higher risk of AL, particularly within 2 weeks of DLI formation. On the basis of this study, routine early ileostomy closure cannot be recommended.

Neuronavigation improves intraoperative visualization of the cranial structures, which is valuable in percutaneous surgical treatments for patients with trigeminal neuralgia (TN) who are refractory to pharmacotherapy or reluctant to receive open surgery. The objective of this review was to evaluate the available neuronavigation-guided percutaneous surgical treatment modalities with cannulation of foramen ovale to TN, and their relative benefits and limitations. ⋯ Neuronavigation-guided percutaneous trigeminal rhizotomies showed possible superior pain relief outcomes to that of conventional rhizotomies in TN, with the benefits of radiation reduction and lower complication development rates. The limitations of neuronavigation remain its high cost and limited availability. Higher-quality prospective studies and randomized clinical trials of neuronavigation-guided percutaneous trigeminal rhizotomy were lacking.

The past 20 years have seen a dramatic shift in our understanding of the role of the immune system in initiating and maintaining pain. Myeloid cells, including macrophages, dendritic cells, Langerhans cells, and mast cells, are increasingly implicated in bidirectional interactions with nerve fibres in rodent pain models. However, our understanding of the human setting is still poor. ⋯ The directionality of results between studies was inconsistent, although the clearest pattern was an increase in macrophage frequency across conditions, phases, and tissues. Myeloid cell definitions were often outdated and lacked correspondence with the stated cell types of interest; overreliance on morphology and traditional structural markers gave limited insight into the functional characteristics of investigated cells. We therefore critically reappraise the existing literature considering contemporary myeloid cell biology and advocate for the application of established and emerging high-dimensional proteomic and transcriptomic single-cell technologies to clarify the role of specific neuroimmune interactions in chronic pain.

T2-weighted Imaging Hyperintensity and Transcranial Motor-evoked Potentials During Cervical Spine Surgery: Effects of Sevoflurane in 150 Consecutive Cases.
There is debate on the impact of inhalational esthetic agents on transcranial motor evoked potentials (TcMEPs) during intraoperative neuromonitoring. Current guidelines advise their avoidance, which contrasts with common clinical practice. ⋯ Balanced anesthesia with 0.5 MAC sevoflurane in patients with and without radiological evidence of myelopathy/SCI allows reliable TcMEP monitoring. However, in communication with surgical and neuromonitoring teams, it may be advisable in a subset of patients to avoid or discontinue sevoflurane in favor of a propofol/opioid-based anesthetic to ensure adequate and reproducible TcMEPs.

Randomized Controlled Trial
Education can reassure people with rotator cuff-related shoulder pain: a 3-arm, randomised, online experiment.
We aimed to investigate the immediate effect of best practice education (with and without pain science messages) and structure-focused education on reassurance among people with rotator cuff-related shoulder pain. We conducted a 3-arm, parallel-group, randomised experiment. People with rotator cuff-related shoulder pain were randomised (1:1:1) to (1) best practice education (highlights that most shoulder pain is not serious or a good indicator of tissue damage and recommends simple self-management strategies); (2) best practice education plus pain science messages (which attempt to improve understanding of pain); and (3) structure-focused education (highlighting that structural changes are responsible for pain and should be targeted with treatment). ⋯ Adding pain science messages to best practice education slightly increased both measures of reassurance (0.2, 95% CI 0.0-0.4). Clinicians treating patients with rotator cuff-related shoulder pain should highlight that most shoulder pain is not serious or a good indicator of tissue damage and recommend simple self-management strategies. The benefit of adding pain science messages is small.
