Randomized Controlled Trial
Subcutaneous Injection of Triamcinolone and Lidocaine to Prevent Postherpetic Neuralgia.
Herpes zoster (HZ) is associated with inflammation of the peripheral nerves, which is considered to be an important cause of postherpetic neuralgia (PHN). Interventions aimed at reducing this inflammation could prevent PHN. One option is the epidural administration of corticosteroid and local anesthetic. However, several authors have reported a risk of arachnoiditis with epidural corticosteroids. Subcutaneous injection in an outpatient setting is a safer option. However, there is limited evidence of the effectiveness of this alternative for preventing PHN. ⋯ Subcutaneous injection, lidocaine, triamcinolone, postherpetic neuralgia, prevention.

Randomized Controlled Trial
Randomized Placebo-Controlled Placebo Trial to Determine the Placebo Effect Size.
It is the gold standard to use a placebo treatment as the control group in prospective randomized controlled trials (RCTs). Although placebo-controlled trials can reveal an effect of an active treatment, the pure effect of a placebo treatment alone has never been presented or evaluated. No evidence-based, placebo-therapeutic options are currently available, and no placebo-controlled trials have been performed to elucidate the pure placebo effect. ⋯ Pain, randomized controlled trial, RCT, placebo, effect size, inverse placebo, study, pain therapy.

Randomized Controlled Trial
Evaluating the Adjuvant Effect of Dexamethasone to Ropivacaine in Transversus Abdominis Plane Block for Inguinal Hernia Repair and Spermatocelectomy: A Randomized Controlled Trial.
The transversus abdominis plane (TAP) block is a relatively straightforward regional technique used for postoperative analgesia in patients undergoing abdominal surgeries. Various adjuvants have been used in past to prolong the duration of action of analgesia in peripheral nerve blocks. Several studies investigating the analgesic efficacy of dexamethasone added to local anesthetic agents, such as bupivacaine, have shown promising results. However, there are few studies comparing the efficacy of dexamethasone with ropivacaine. ⋯ Regional anesthesia, transversus abdominis plane, dexamethasone, ropivacaine.
