Randomized Controlled Trial
Impact of Data Imputation Methodology on Pain Assessment over 24 Hours in a Randomized, Placebo-Controlled Study of Gabapentin Enacarbil in Patients with Neuropathic Pain Associated with Postherpetic Neuralgia.
To assess the impact of gabapentin enacarbil on primary and secondary pain endpoints using three data imputation methodologies in a randomized phase II study of adult patients with postherpetic neuralgia. ⋯ Gabapentin enacarbil (1,200 mg, 2,400 mg, and 3,600 mg) was effective and well tolerated in patients with postherpetic neuralgia compared with placebo, as confirmed by three different and robust statistical methodologies.

Clinical Trial
Comparison of Acute and Chronic Pain after Open Nephrectomy versus Laparoscopic Nephrectomy: A Prospective Clinical Trial.
We evaluated postoperative pain intensity and the incidence of chronic pain in patients with renal cell carcinoma undergoing laparoscopic or open radical nephrectomy. In this prospective study, 27 laparoscopic nephrectomy (Group LN) and 25 open nephrectomy (Group ON) patients were included. All patients received paracetamol infusion and intramuscular morphine 30 minutes before the end of the operation and intravenous patient controlled analgesia with morphine postoperatively. ⋯ Chronic pain at 6 months after surgery was observed in 1 ON patient (4%) and 1 LN patient (3.7%, P = 0.9). This study demonstrated that postoperative acute pain scores were not different after laparoscopic or open nephrectomy and patients undergoing laparoscopic or open nephrectomy were at equal risk of developing CPSP. Pain control should be carefully planned in order to reduce early postoperative pain and also potentially prevent CPSP.

Pain assessment in Intensive Care Units (ICU) can be performed based on validated instruments as the Behavioral Pain Scale (BPS). Despite the existence of this clinical score, there is no Brazilian version of it to assess critically ill patients. This study aimed to translate the BPS into Brazilian Portuguese, verify its psychometric properties (reliability, validity, and responsiveness) and the correlation between pain measured and heart rate (HR), blood pressure (BP), Ramsay, and RASS scores. ⋯ Brazilian BPS has high responsiveness and capacity to detect pain intensity in different situations in the ICU routine. This preliminary study proved the feasibility and importance of valid this scale in Brazil in order to improve critically ill patients care.
