Multicenter Study
Validation of the Short Form of the Brief Pain Inventory (BPI-SF) in Spanish Patients with Non-Cancer-Related Pain.
The Brief Pain Inventory (BPI) is a widely used pain measurement tool. There are 2 versions, the BPI Long Form (BPI-LF) and Short Form (BPI-SF), which share 2 core scales measuring pain severity and pain interference but which use different recall periods (24 hours vs. 1 week). To date, the BPI-SF has not been validated for use in Spain. ⋯ Substantial improvements were seen on both subscales after 3 months of treatment (ES of 1.76 for pain severity and 1.51 for pain interference). Recall period did not noticeably affect scores; ICCs (95% CI) between the long and short versions were 0.946 (0.938 to 0.954) and 0.929 (0.919 to 0.939) for the severity and interference subscales, respectively. The Spanish version of the BPI-SF is a valid and reliable instrument to measure pain severity and interference.

Randomized Controlled Trial Comparative Study
Intravenous Subdissociative-Dose Ketamine Versus Morphine for Analgesia in the Emergency Department: A Randomized Controlled Trial.
We assess and compare the analgesic efficacy and safety of subdissociative intravenous-dose ketamine with morphine in emergency department (ED) patients. ⋯ Subdissociative intravenous ketamine administered at 0.3 mg/kg provides analgesic effectiveness and apparent safety comparable to that of intravenous morphine for short-term treatment of acute pain in the ED.

Multicenter Study Observational Study
Long-Term Outcome of the Management of Chronic Neuropathic Pain: A Prospective Observational Study.
This prospective observational cohort study addressed the long-term clinical effectiveness of the management of chronic neuropathic noncancer pain at 7 Canadian tertiary pain centers. Patients were treated according to standard guidelines and were followed at 3, 6, 12, 18, and 24 months. Standard outcome measures for pain, mood, quality of life, and overall treatment satisfaction were administered, with the primary outcome measure designated as the composite of 30% reduction in average pain intensity and 1-point decrease in the mean Interference Scale Score (0-10) of the Brief Pain Inventory at 12 months relative to baseline. ⋯ Opioid therapy may not be beneficial for the long term. Perspective: Evidence-based treatment of chronic neuropathic pain provides long-term benefit in only about one-quarter of patients seen in tertiary care centers. Opioid therapy may not be beneficial.

Observational Study
Cross-cultural adaptation and psychometric properties of an Arabic version of the Shoulder Pain and Disability Index.
The aim of the present study was to translate, culturally adapt, and validate the Arabic version of the shoulder Pain and Disability Index (SPADI). This was an observational reliability and validity study. We recruited 64 patients with shoulder pain and dysfunction with a wide variety of diagnoses. ⋯ The translated version of SPADI in the Arabic language showed excellent internal consistency and test-retest reliability. Validity was shown by substantial correlations between SPADI and Quick DASH, NRS, and active shoulder ROM. The Arabic SPADI is recommended for the evaluation of patients with shoulder dysfunction.

The purpose of this study was to examine the reliability of pressure pain threshold (PPT) and pain tolerance assessment in the finger over three testing days. PPT was assessed in the middle finger at the mid-point between the proximal and distal interphalangel joints in 49 college-aged men on three occasions (day 1, day 2, day 3) each separated by 48 h. The pressure evoking PPT was subsequently applied for up to 120 s to assess pain tolerance, whereas pain intensity was rated every 15 s. ⋯ Ratings of pressure pain intensity rose over time during the 120 s test (P≤0.002) and were reduced on testing day 3 compared with day 1 (P=0.029). Our results suggest the use of least one familiarization session would lead to significantly improved day-to-day reliability of PPT assessment in the finger. In addition, the application of the force eliciting PPT was a poor discriminator of pain tolerance because of the fact the majority of participants (146 out of 147 sessions) could tolerate the stimulus for the entire 120 s.
