Review Meta Analysis
Efficacy, acceptability and safety of Internet-delivered psychological therapies for fibromyalgia syndrome: A systematic review and meta-analysis of randomized controlled trials.
This systematic review aimed at evaluating the efficacy, acceptability and safety of Internet-based psychological therapies (IPTs) in fibromyalgia syndrome (FMS). Clinicaltrials.gov, Cochrane Library, MEDLINE, PsycINFO and SCOPUS were searched from inception to January 2018. Randomized controlled trials (RCTs) comparing IPTs with controls were analysed. ⋯ The data available did not allow statistical comparisons between unguided and guided ICBTs and of ICBTs versus traditional face-to-face therapies. ICBTs provided a clinically relevant benefit over control interventions in reducing negative mood and disability at the end of treatment. SIGNIFICANCE: Internet-delivered cognitive behavioural therapies provided a clinically relevant benefit in reducing negative mood and disability in patients with FMS at the end of treatment if compared to waiting list, treatment as usual and attention controls.

Randomized Controlled Trial
Ultrasound-guided adductor canal block after arthroscopic anterior cruciate ligament reconstruction: Effect of adding dexamethasone to bupivacaine, a randomized controlled trial.
Dexamethasone improves the quality and duration of peripheral nerve block when used as an adjuvant to local anaesthetic. We evaluated the effect of adding dexamethasone to bupivacaine on the duration of postoperative analgesia in patients undergoing knee arthroscopy using ultrasound-guided adductor canal block. ⋯ Adding dexamethasone to bupivacaine in adductor canal block significantly increases the duration of sensory block, time to first analgesic requirement and patients' satisfaction score in anterior cruciate ligament arthroscopic surgery.

Case Reports
A case report of sustained resolution of cancer pain by continuous perineural infusion of local anaesthetic.
Opioids are currently offered as first-line treatment for chronic pain from cancer. Continuous regional analgesia could be an alternative to opioids. However, the required duration of catheterization and the sustained analgesic effects of this technique after catheter removal have yet to be clarified. ⋯ This case report provides new insights into the treatment of cancer pain. The most interesting finding is that the pain did remained absent after 45 days of continuous infusion of local anaesthetics through an interscalene catheter. We postulated that local anaesthetic drugs have an impact on pain memory.

The assessment of pressure pain has become an integral part in pain research. The distribution of pressure under a plunger can be uneven. However, measurements based on conventional devices show the applied force or mean pressure, failing to take local pressure peaks into account. Our main question was whether peak pressures under the probe are responsible for pain onset. ⋯ This study adds some important considerations for the use of pressure algometers. It was found that during pressure pain thresholds readings distinct peak pressure profiles could arise, which may influence the perception of pain. Peak pressure could be another contributing factor, which may explain some of the high variability in pressure pain readings.

We hypothesized that prepulse modulation (PPM) would be altered in trigeminal neuralgia (TN) if suprasegmental inhibitory network involvement was present and tested our hypothesis in a group of patients with classical TN. ⋯ There is a bilateral prepulse inhibition deficit in TN, even on the asymptomatic side. Our findings provide electrophysiological evidence for suprasegmental changes and loss of filtering activity at the brainstem in level TN.
