Randomized Controlled Trial Multicenter Study Clinical Trial
Tolerability and efficacy of two synergistic ratios of oral morphine and oxycodone combinations versus morphine in patients with chronic noncancer pain.
Analgesic synergy and improved tolerability have been reported for flexible dose morphine and oxycodone combinations. This report describes two studies with similar double-blind, randomized, 7-day crossover designs (up to 7 days per arm) conducted to 1) explore the analgesic and safety benefit offixed ratio of morphine (M) and oxycodone (0) combinations (MOX) and 2) define the optimal ratio for morphine and oxycodone combination. ⋯ A 3:2 or 1:2 fixed ratio combination of morphine and oxycodone (MOX) produced analgesic synergy and a tolerability profile improvement in patients with chronic noncancer pain.

Multicenter Study Comparative Study
Oral fluid drug testing of chronic pain patients. II. Comparison of paired oral fluid and urine specimens.
A clinical study was conducted to compare the use of oral fluid to urine for compliance monitoring of pain patients. Patients (n = 133) undergoing treatment for chronic pain at four clinics participated in the study and provided paired oral fluid and urine specimens. Oral fluid specimens were collected with Quantisal(TM) saliva collection devices immediately following urine collection. ⋯ Cohen's Kappa value was 0.64, indicating "substantial" agreement. The primary exceptions to agreement were the lower detection rates for hydromorphone, oxymorphone, and benzodiazepines in oral fluid compared to urine. The authors conclude that, overall, oral fluid tests produced comparable results to urine tests with some minor differences in detection rates for different drug classes.

Despite effective analgesic therapy, inadequate pain control is frequently perceived by patients and caregivers. ⋯ Physician-patient communication and information provided to patients are essential aspects of patient perceptions and attitudes towards control of cancer-related pain. Pain is seen as a condition that may be controlled but affects the capacity to lead a normal life.

Multicenter Study[Are we controlling the sedation in ICU? A multicenter study results].
The aim of this study is to evaluate the issues of sedation and analgesia in all-purpose ICUs in Russia. To obtain that, a single-day observational survey was performed in 55 ICUs of Ural and Siberia regions. ⋯ Sedation indications do not satisfy the modern concept, sedation level evaluation scores are used only in 13%, schemes and drugs are traditional. The results of this study may serve as a reason for discussion of necessity of introducing of sedative and analgetic therapy in ICU standarts.

Randomized Controlled Trial Multicenter Study Comparative StudyThe efficacy of tramadol/acetaminophen combination tablets (Ultracet®) as add-on and maintenance therapy in knee osteoarthritis pain inadequately controlled by nonsteroidal anti-inflammatory drug (NSAID).
The purpose of this study is to compare the efficacy of tramadol 37.5 mg/acetaminophen 325 mg combination tablets (tramadol/APAP) with that of nonsteroidal anti-inflammatory drugs (NSAIDs) as maintenance therapy following tramadol/APAP and NSAID combination therapy in knee osteoarthritis (OA) pain which was inadequately controlled by NSAIDs. Subjects with knee OA for over 1 year and moderate pain (numerical rating scale [NRS] ≥5) despite at least 4 weeks' NSAID therapy (meloxicam 7.5 mg or 15 mg qd or aceclofenac 100 mg bid) received tramadol/APAP add-on (combination with NSAID) for 4 weeks. Thereafter, subjects with significant pain improvement (NRS <4) were randomized to receive either tramadol/APAP or NSAID for 8 weeks. ⋯ Overall adverse event rates were similar in both groups. Tramadol/APAP add-on significantly improved knee OA pain which had been inadequately controlled by NSAIDs. In those subjects who showed favorable response to tramadol/APAP and NSAID combination therapy, both tramadol/APAP and NSAIDs were effective at maintaining the pain-reduced state and there was no significant difference in efficacy between tramadol/APAP and NSAIDs.
