N-methyl-D-aspartate receptor (NMDAR) antagonists have been shown to reduce mechanical hypersensitivity in animal models of inflammatory pain. However, their clinical use is associated with significant dose-limiting side effects. Small-conductance Ca-activated K channels (SK) have been shown to modulate NMDAR activity in the brain. ⋯ Double immunostaining shows coexpression of SK3 and NMDAR subunit, NR1, compatible with functional interaction. Moreover, we demonstrate that i.t. coadministration of NS309 with an NMDAR antagonist reduces the dose of NMDAR antagonist, DL-2-amino-5-phosphonopentanoic acid (DL-AP5), required to produce antinociceptive effects in the CFA model. This reduction could attenuate the unwanted side effects associated with NMDAR antagonists, giving this combination potential clinical implications.

Randomized Controlled TrialOptimising abdominal space with deep neuromuscular blockade in gynaecologic laparoscopy - a randomised, blinded crossover study.
Insufflation of the abdomen during laparoscopy improves surgical space, but may cause post-operative shoulder pain. The incidence of shoulder pain is reduced using a lower insufflation pressure, but this may, however, compromise the surgical space. We aimed at investigating whether deep neuromuscular blockade (NMB) would enlarge surgical space, measured as the distance from the sacral promontory to the trocar in patients undergoing gynaecologic laparoscopy. ⋯ Deep NMB enlarged surgical space measured as the distance from the sacral promontory to the trocar. The enlargement, however, was minor and the clinical significance is unknown. Moreover, deep NMB improved surgical conditions when suturing the abdominal fascia.

Randomized Controlled Trial
Repetitive transcranial magnetic stimulation in neuropathic pain secondary to malignancy: A randomized clinical trial.
Significant analgesic effects of repetitive transcranial magnetic stimulation (rTMS) have been found in several studies of patients with chronic pain of various origins, but never for malignancy. The objective of this study was to assess the efficacy of 10 sessions of rTMS over the primary motor cortex (M1) in patients suffering from malignant neuropathic pain. ⋯ The results demonstrate that 10 rTMS sessions over the M1 can induce short-term pain relief in malignant neuropathic pain.

The COMFORT behaviour scale (COMFORT-B scale) is widely used in paediatric intensive care units to assess young children's pain and distress. It is also used to assess the impact of treatment interventions, but little is known on the scale's sensitivity to detect changes between before and after measurements following an intervention. This study explored the sensitivity to change of the COMFORT-B scale. ⋯ This is the first study demonstrating that the COMFORT-B scale detects treatment-related changes in pain or distress intensity. This implies that COMFORT-B assessments can effectively guide analgesic and sedation treatment in critically ill children.
