METHODS: A discrete choice experiment was developed to include 7 attributes valued in cancer management: physical, psychological and social functioning, pain control, survival, place of death, and cost. Patients were recruited via convenience sampling from 2 Malaysian public hospitals. The survey questionnaire was administered to patients within 6 months of their cancer diagnosis with a follow-up 3 months later. Conditional logit regression was used to estimate the preference weight, relative attribute importance, and willingness to pay.

RESULTS: One hundred valid responses were collected at baseline and 45 at follow-up. Respondents placed higher values on QoL improvements from severe to moderate or mild levels and to achieve home death over survival extension from 6 to 18 months. However, additional improvements (from moderate to mild) in some of the QoL outcomes were not valued as highly as life extension from 12 to 18 months, showing that it was vital for patients to avoid being in "severe" health dysfunction. Improving physical dysfunction from severe to mild yielded 3 times as much value as additional 1-year survival. After 3 months, the respondents' preferences changed significantly, with increased relative attribute importance of physical functioning, pain control, and cost.

Objective: To compare the effects of CSE and PNF training on pain-related outcomes and trunk muscle activity in CLBP patients.

Methods: Forty-five CLBP patients, ranging from 18 to 50 years of age, were randomly divided and assigned to either a four-week CSE, four-week PNF training, or control group. Pain-related outcomes, including pain intensity, functional disability and patient satisfaction, as well as superficial and deep trunk muscle activity were assessed before and after the four-week intervention, and at a three-month follow-up.

Results: Compared to the control group, those in the CSE and PNF training groups showed significant improvements in all pain-related outcomes after the four-week intervention and at three-month follow-up (P < 0.01). Following the four-week intervention, both CSE and PNF training groups demonstrated significant improvement in deep trunk muscle activity, including the transversus abdominis (TrA) and superficial fibres of lumbar multifidus (LM), compared to the control group (P < 0.05).

MATERIALS AND METHODS: Antinociceptive activity of ethanol pomegranate extract was examined using three models of pain: the writhing test, the hot tail flick test and the plantar test. The ethanolic extract of pomegranate was administered by oral gavages in doses of (100,150 and 200mg/kg, p.o (orally)), for all the tests and compared with aspirin (100mg/kg, p.o.) which was considered as the standard drug. Phytochemical screening and HPLC analysis of the plant species was carried out.

RESULTS: In the writhing test, the index of pain inhibition (IPI) was 37% for ethanolic extract of pomegranate (200mg/kg, p.o.), and 59% for aspirin. In the hot tail flick test, the ethanolic extract of pomegranate (200mg/kg, p.o.), has shown significant analgesia reaching its peak at 60 min maximum possible analgesia (MPA), was 24.1% as compared with aspirin 37.5%. Hyperalgesia was successfully induced by the plantar test and the ethanol extract of pomegranate (100,150,200mg/kg, p.o.), reduced the hyperalgesia in a dose dependent manner comparable to aspirin at (100mg/kg, p.o.). HPLC analysis revealed the presence of gallic acid, ellagic acid and Punicalagins A&B.

MATERIALS AND METHODS: In this randomized, double-blind, placebo-controlled prospective study, we enrolled 40 children undergoing tonsillectomy. Anesthetic care was standardized. Intraoperative analgesia was provided with remifentanil 0.5 microg x kg(-1) followed by an infusion of 0.25 microg x kg(-1) x min(-1). Group I (ketamine, n = 20) received a bolus dose of ketamine 0.5 mg x kg(-1) followed by a continuous infusion of 2 microg x kg(-1) x min(-1) before start of surgery. The infusion was stopped when surgery ended. Group II (placebo, n=20) received normal saline in the same manner. Pain was assessed postoperatively using the Children's Hospital Eastern Ontario Pain Scale (CHEOPS; range of scores 4 13), and total morphine consumption was recorded in the postanesthesia care unit (PACU). Patients were transferred to the ward and morphine was administered via a patient-controlled analgesia (PCA) device and analgesia was recorded using a visual analogue scale (VAS) (0 - 10).

RESULTS: Intraoperative remifentanil consumption was not different between the ketamine group (0.29+/-0.09 microg x kg x min(-1) ) and the control group (0.24+/-0.07 microg x kg x min(-1)). There were no significant differences between CHEOPS scores and VAS score between the two groups. The total mean morphine consumption in the ward was not significantly different between the two groups: 376.5 +/-91.6 microg x kg(-1) with ketamine and 384.4+/-97.3 microg x kg(-1) with placebo. The time-to-first analgesic requirement was also similar in both groups.
