Review Meta Analysis
High Prevalence of Neuropathic Pain Component in Patients with Low Back Pain: Evidence from Meta-Analysis.
Low back pain (LBP) is a complex syndrome which includes a nociceptive (NcP) component, a neuropathic (NeP) component, or a mixture of components (mixed pain). The NeP component (NePC) in LBP is defined as the presence of NeP with or without an NcP. ⋯ Neuropathic pain, nociceptive pain, low back pain, symptom-based questionnaire, chronicity.

Review Case Reports
Percutaneous Vertebroplasty for Primary Non-Hodgkin's Lymphoma of the Thoracic Spine: Case Report and Review of the Literature.
Primary non-Hodgkin's lymphoma of the vertebra is rare in the spine of the elderly. The clinical presentation and radiological features are unspecific, which make it more difficult for diagnosis. We report a case of a 79-year-old woman complaining of serious backache without any injury. ⋯ The patient was diagnosed with primary bone lymphoma finally. Due to the previous condition of the patient, R-miniCHOP chemotherapy was applied following the surgery in the department of hematology. Until the 9 months follow-up, the clinical result was still satisfactory.

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.

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.
