In a double-blind study the analgesic efficacy and acceptability of meptazinol 200 mg was compared with placebo in patients suffering from acute or chronic pain. Patients were randomly allocated to receive either 200 mg of meptazinol or one tablet of placebo 4 to 6 hourly over a 14-day period. Clinical evaluations were made by the physician at baseline and again at the end of the study. The patients made daily recordings of pain using a visual analogue scale. The results showed that meptazinol was a more effective and acceptable analgesic than placebo. There was no significant difference in the incidence of adverse effects reported by patients in either treatment group.

Cure Rates

In a randomized double-blind study fifty-four patients suffering from acute maxillary sinusitis were treated for 10 days with daily doses of sulphadiazine/trimethopim (1 g) and sulphamethoxazole/trimethoprim (1.92 g), respectively. The efficacy was evaluated clinically at two follow-up visits. X-ray investigations were performed at admission and after the therapy. Of thirty-nine patients finally evaluated, thirty-seven showed a favourable result. After 6–8 days of therapy there was significant difference in cure rates in favour of sulphadiazine/trimethoprim (p < 0.05) while the outcome as evaluated after treatment was similar for both drugs.

IntroductionUp to 50% of patients with OCD have failed to respond in SSRI trials, so looking for pharmacological alternatives in treatment of obsessive compulsive disorder (OCD) seems necessary.ObjectivesSurveying duloxetine augmentation in treatment of resistant OCD.AimsStudy the effects of serotonin-norepinephrine enhancers for treatment of OCD.MethodsThis augmentation trial was designed as an 8-week randomized controlled, double blind study. Forty-six patients suffering from OCD who had failed to respond to at least 12 weeks of treatment with a selective serotonin reuptake inhibitor (fluoxetine, citalopram or fluvoxamine) were randomly allocated to receive duloxetine or sertraline plus their current anti OCD treatment. Yale-Brown Obsessive Compulsive Scale (Y-BOCS) was the primary outcome measure.ResultsForty-six patients (24 of 30 in duloxetine group and 22 of 27 in sertraline group) completed the trial. Both groups showed improvement over the 8-week study period (mean Y-BOCS total score at week 8 as compared with baseline: P < 0.001 and P < 0.001) without significant difference (P = 0.861). Those receiving duloxetine plus their initial medications experienced a mean decrease of 33.0% in Y-BOCS score and the patients with sertraline added to their initial medication experienced a mean decrease of 34.5% in Y-BOCS.ConclusionsOur double blind controlled clinical trial showed duloxetine to be as effective as sertraline in reducing obsessive and compulsive symptoms in resistant OCD patients. However, it needs to be noted that our study is preliminary and larger double blind placebo controlled studies are necessary to confirm the results.Disclosure of interestThe authors have not supplied their declaration of competing interest.

In this multiple-dose, double-blind study 100 patients with moderate, severe or very severe pain following orthopaedic surgery were randomly assigned to receive ketorolac, a nonsteroidal anti-inflammatory drug with potent analgesic properties (10 mg), or the standard regimen of Ketogan® (a combination product containing the narcotic analgesic, ketobemidone, plus a spasmolytic agent) by intramuscular injection every 1 – 6 h as needed for pain. When patients were able to tolerate an oral diet and were expected to respond to oral analgesic medication, based on overall pain sensitivity, they were switched to oral doses of the same medication every 4 – 6 h as needed. A maximum of four daily doses of medication was allowed for up to 10 days. The severity of pain was scored on a five-point scale and was recorded before the first intramuscular dose, at fixed time points therafter for up to 6 h and at the end of each day. Both treatments were effective immediately after the first dose and during the subsequent multiple-dose phase. There were no statistically significant differences between ketorolac and Ketogan®. The results show that 10-mg doses of ketorolac in intramuscular injections followed by 10-mg doses of oral ketorolac are as effective as Ketogan® for the treatment of pain following orthopaedic surgery. Ketorolac appears to be better tolerated than Ketogan® since significantly fewer patients reported adverse events ( P = 0.004) when taking ketorolac.

Butorphanol (1 mg and 2 mg) and meperidine (40 mg and 80 mg), given intravenously, were evaluated for analgesic efficacy and safety in a double-blind randomized study employing 200 consenting pre-partum patients in moderate to severe pain during the late first stage of labour. Both drugs provided adequate relief of pain to the mothers. There was no significant difference in the rate of cervical dilation, the foetal heart rate, the Apgar score, pain relief or neonatal neurobehavioural scores between those receiving butorphanol and those receiving meperidine. Twenty-two mothers who received butorphanol and eleven who received meperidine nursed their infants with no adverse effects observed. Side-effects were generally infrequent in this study; however, more side-effects were reported by the patients and observed by the investigator in the meperidine-treated cases (13%) than in the cases treated with butorphanol (2%).

The onset, quality and duration of analgesia and side-effects of a single bolus dose of either epidural pethidine 50 mg or fentanyl 100 mcg, administered immediately post-delivery, were compared in a randomised, double-blind study of fifty-five women undergoing epidural caesarean section. The onset of effect was more rapid with fentanyl, a significantly larger number of women achieving complete pain relief fifteen minutes post-administration (P<0.05). The quality of analgesia was good in both groups and the quality and duration of effective analgesia not significantly different. The incidence and severity of side-effects were low, with no significant difference between groups. One patient in the pethidine group experienced early onset respiratory depression; however, she did not require active treatment. Epidural fentanyl 100 mcg appears to offer a small clinical advantage over pethidine 50 mg for intraoperative use during caesarean section.

Background: Ondansetron has been used successfully for prophylaxis and treatment of intrathecal morphine induced pruritus. Gabapentin has anxiolytic, antiemetic, antipruritic effects and has also been shown to potentiate the analgesic effect of intrathecally or epidurally administered opioids. Materials and method: We compared the effectiveness of oral gabapentin with intravenous ondansetron to prevent incidence of intrathecal morphine induced pruritus. In a prospective, double-blind study, sixty patients aged 18-65 years with ASA physical status I and II undergoing surgery under subarachnoid block were randomized to receive placebo tablets (ondansetron group) or gabapentin 1200 mg (gabapentin group) 2 hours before surgery. Patients receiving placebo tablets received 8 mg of intravenous ondansetron and those receiving gabapentin received 4 ml of intravenous normal saline just prior to subarachnoid block with 3 ml of 0.5% hyperbaric bupivacaine plus 0.2 mg morphine. The incidence, onset, severity, location of pruritus and incidence of side effects were studied for next 24 hours. Results: The overall incidence of pruritus was 48.3%. The incidence, severity, location of pruritus was comparable between the two groups. There was significant difference between the onset of pruritus between groups (p=0.009). The incidence and grade of nausea vomiting, requirement of intraoperative sedation was comparable between groups. The incidence of urinary retention was significantly high in gabapentin group (p=0.020). Respiratory depression was observed in one patient. Conclusion: A single dose of 1200 mg oral gabapentin 2 hours before, is as effective as prophylactic intravenous ondansetron 8 mg for prevention of intrathecal morphine induced pruritus.

9007 Introduction: Although pyridoxine has been used empirically for the prevention of HFS associated with capecitabine, its efficacy has not been proven yet. We performed a prospective randomized double-blind study to determine whether pyridoxine can prevent the development of HFS when given concurrently with capecitabine. Method: Chemotherapy-naive patients (pts) with gastrointestinal tract cancers who were going to have capecitabine-containing chemotherapy were randomized to receive either oral pyridoxine (200 mg/day) or placebo daily during chemotherapy after stratified by chemotherapy regimen: 1) capecitabine alone, 2) capecitabine and cisplatin, or 3) docetaxel, capecitabine, and cisplatin. The patients were observed until grade 2 or 3 HFS (by NCI CTC version 2.0) developed or capecitabine containing chemotherapy ended. When grade 2 or 3 HFS developed in pts in placebo group, the pts were randomized again to receive either pyridoxine or placebo for next cycle of chemotherapy in order to determine whether pyridoxine could improve the HFS. Result: From Jun 2004 to Oct 2005, total 389 pts were entered onto the study. But, 29 pts (15 in placebo group and 14 in pyridoxine group) were excluded from the study because of ineligibility or pts’ refusal. Pts’ characteristics were well balanced between the 2 groups. Grade 2 or 3 HFS developed in 55 of 180 (30.6%) pts in placebo group and in 57 of 180 (31.7%) pts in pyridoxine group. (p=0.788) The median cycles of chemotherapy to grade 2 or 3 HFS was 3 in both groups. The mean cumulative dose of capecitabine until occurrence of grade 2 or 3 HFS was not different statistically between the two groups. (221,157.5 mg/m2 vs. 259,808.5 mg/m2, p=0.788). Total 44 of 55 pts in placebo group who had grade 2 or 3 HFS were randomized to receive either placebo or pyridoxine at next cycle. There was no significant difference between the two groups in the proportion of pts with improvement of HFS (43% vs 48%, p=0.94). Conclusion: These results indicated that pyridoxine is not effective for the prevention of HFS associated with capecitabine therapy. No significant financial relationships to disclose.

Paralleling developments in other areas of clinical psychology, psychological theories of chronic pain have evolved from the purely behavioural models of several decades ago, to those that have increasingly recognized the importance of cognitive constructs (without necessarily neglecting the influence of behavioural factors that remains significant). As is well established in the domains of anxiety and depression, pain related cognitions and coping strategies are now considered to be just as, if not more, important as behavioural constructs such as reinforcement contingencies. At the same time, however, some of the exciting developments in other clinical areas have only just begun to receive due attention from those interested in pain. In particular, the “safety seeking behaviours” construct, which has received a considerable amount of attention in recent years from anxiety researchers, appears to have been virtually ignored by those researching pain. Although related constructs such as “fear avoidance” have increasingly been recognized and investigated, specific reference to safety behaviours (in relation to pain) does not seem to have occurred. This paper presents a brief overview of how the concept of safety seeking behaviours could be applied to chronic pain patients. Although not advancing a radically new approach, it is argued that there are theoretical and clinical advantages to integrating safety seeking behaviours in to psychological models of pain.

Abstract Objective: Kaixinsan (KXS) decoction, as an ancient’s herbal formula, has been demonstrated to be active in various animal models resembling human depression with multi-target effects. This very first study evaluated the efficacy and tolerability of Shen Zhi Ling (SZL) tables (KXS preparation), compared with fluoxetine (FLX, positive comparator), in patients with mild to moderate depressive disorder.Methods: In this randomized double-blind parallel-group study, 156 patients with mild to moderate depression without taken any antidepressants in the past 6 months or 4 straight weeks were randomized to receive either 3.2g/d SZL plus 20mg/d FLX placebo (SZL group) or 20mg/d FLX plus 3.2g/d SZL placebo (FLX group), for 8 weeks. Their clinical presentations and some metabolic indexes were assessed during the 8 weeks visiting period.Results: Patients in SZL group showed a statistically significant improvement after 8 weeks of treatment in HAMD-17 score (18.79±2.09 to 4.43±4.71, p<0.001) and self-rating depression scale (SDS) score (58.49±8.89 to 39.84±12.09, p<0.001), but not in N-back total respond time (1145.55±608.26 to 1128.47±387.49, p>0.05). In addition, no significant difference at 8 weeks of treatment was found between SZL and FLX groups in SDS score (39.84±12.09 vs. 36.63±12.44) and N-back respond time (1128.47±387.49 vs. 1089.43±352.08) as well as reduction of HAMD-17 score (14.79±4.88 vs. 15.24±4.29) (p>0.05 for all). However, the serum APOB, APOC3 and ALB levels and HDL-C/LDL-C ratio decreased significantly in patients after SZL treatment, while only APOB/APOA1 ratio decreased significantly in FLX group. Other metabolic indexes did not alter significantly after treated with SZL or FLX.Conclusion: The efficacy and safety profile of SZL are comparable to that of fluoxetine in patients with mild to moderate depression. The beneficial effect of SZL is probably associated with improvement of lipid metabolic balance.
