Background: Canada does not have a standardized ethical and practice framework for continuous palliative sedation therapy (CPST). Although a number of institutional and regional guidelines exist, Canadian practice varies. Given the lack of international and national consensus on CPST, the Canadian Society for Palliative Care Physicians (CSPCP) formed a special task force to develop a consensus-based framework for CPST.
Objective: Through a preliminary review of sedation practices nationally and internationally, it was determined that although considerable consensus was emerging on this topic, there remained both areas of contention and a lack of credible scientific evidence to support a definitive clinical practice guideline. This led to the creation of a framework to help guide policy, practice, and research.
Methods: This framework was developed through the following steps: 1) literature review; 2) identification of issues; 3) preparation of a draft framework; 4) expert consultation and revision; 5) presentation at conferences and further revision; and 6) further revision and national consensus building.
Results: A thorough literature review, including gray literature, of sedation therapy at the end of life was conducted from which an initial framework was drafted. This document was reviewed by 30 multidisciplinary experts in Canada and internationally, revised several times, and then submitted to CSPCP members for review. Consensus was high on most parts of the framework.
Conclusion: The framework for CPST will provide a basis for the development of safe, effective, and ethical use of CPST for patients in palliative care and at the end of life.

Various topical drug combination assessed using a neurosensory stent for chronic intraoral neuropathic pain: a pilot study.
J Oral Facial Pain Headache

Chronic intraoral neuropathic pain (NP), often developing post-dental procedures, poses significant management challenges. The prevalent use of systemic treatments, with their frequent substantial side effects, emphasizes the need for alternative therapeutic strategies. Our aim is to explore the efficacy and adherence with a topical drug regimen delivered through a neurosensory stent (NS) for treating chronic neuropathic pain (NP) within the oral cavity.

Purpose: Lumbar puncture is a frequently performed procedure for patients undergoing treatment for acute lymphoblastic leukemia. This brief procedure is frequently performed with sedation in young patients but with only local anesthesia in adults. Adolescent and young adult patients may be cared for by physicians with different training backgrounds and sedation preferences, making the utilization of sedation for lumbar punctures variable among providers.

Oral ganaxolone (ZTALMY), a synthetic analogue of the endogenous neuroactive steroid allopregnanolone, acts as a positive allosteric modulator of synaptic and extra-synaptic γ-aminobutyric acid (GABA) type A receptor function in the CNS. In the EU and the UK, it is approved for the adjunctive treatment of epileptic seizures associated with cyclin-dependent kinase-like 5 (CDKL5) deficiency disorder (CDD) in patients aged 2-17 years. In a multinational phase III study (Marigold), 17 weeks' therapy with adjunctive ganaxolone, administered orally three times daily with food, significantly reduced 28-day major motor seizure frequency from baseline versus placebo in patients aged 2-19 years with CDD-associated refractory epilepsy.

Purpose: To evaluate the feasibility, safety, and short-term (3-month) results of transperineal prostate thermal ablation (TPTA) as a minimally invasive outpatient treatment for benign prostatic hyperplasia (BPH).
Materials And Methods: A prospective nonrandomized study of 25 patients with lower urinary tract symptoms secondary to BPH seeking care at 2 interventional radiology centers between March and July 2024. TPTA was performed using a 17G radiofrequency needle with a 10-mm active tip under unconscious sedation combined with bilateral perineal and periprostatic nerve blocks.
