Pruritis

The purpose of this study is to investigate the effect of neuraxial analgesia initiation on the incidence of pruritus in laboring women. Specifically, this study aim to compare intrathecal fentanyl with epidural fentanyl in order to determine whether the epidural route is associated with a lower occurrence and severity of pruritus. By clarifying these differences, the research seek to optimize analgesic strategies during labor while minimizing opioid-related side effects

The goal of this study is to test the efficacy of Dupixent in improving post-burn itching symptoms versus the current standard of care.

This randomized controlled trial aims to evaluate the effect of polymethylmethacrylate dialysis membranes use on the intensity of pruritus in patients with CKD stage 5D receiving maintenance hemodialysis. The main question it aims to answer is: Does the use of polymethylmethacrylate (PMMA) membranes reduce the intensity of pruritus in dialysis patients? Researchers will compare PMMA membranes to standard polysulfone-based membranes to see if PMMA works to reduce moderate-to-severe pruritis and pruritis-related quality of life. Participants will: * receive maintenance hemodialysis with PMMA or polysulfone membranes for 2 months; * fill in questionnaires about intensity of pruritis and its impact on daily life.
