Background—Does the use of the histamine H2 receptor antagonist ranitidine improve the outcome of patients with gastric cancer?Patients—A total of 222 patients with gastric cancer who had received radical or palliative resection or who were deemed inoperable at presentation.Setting—Hospitals within Yorkshire, the participating clinicians being members of the Yorkshire GI Tumour Group.Methods—A multicentre prospective randomised double blind trial comparing ranitidine 150 mg twice daily with placebo twice daily was undertaken. The principal outcome measures were survival and survival excluding those who died within 30 days of operation.Results—The median survival (95% confidence intervals) was 331 (232 to 393) days for patients in the ranitidine group compared with 187 (143 to 269) for those in the placebo group. The difference in survival was not statistically significant (p = 0.225). When patients who died within 30 days of operation were excluded (21 in the placebo group, 15 in the ranitidine group), the difference in survival remained not significant (p = 0.358). No subgroup could be identified who significantly benefited from treatment, but for patients with stage VIa cancer the median survival was 134 days with placebo compared with 313 days with ranitidine (p = 0.073).Conclusion—This study does not show significant benefit from the use of ranitidine for gastric cancer but further larger studies may be indicated.

Background: Continuous bilateral thoracic paravertebral blockade has been used for analgesia after cardiac surgery, but its efficacy has never been formally tested. Method: Fifty adult patients were enrolled in a double-blind, randomised, controlled study of continuous bilateral thoracic paravertebral infusion of 0.5% lidocaine (1 mg.kg-1.hr-1) for analgesia after coronary surgery. Control patients received a subcutaneous infusion of lidocaine at the same rate through catheters inserted at the same locations as the study group. The primary outcome was morphine consumption at 48 hours using patient-controlled analgesia (PCA). Secondary outcomes included pain, respiratory function, nausea and vomiting. Serum lidocaine concentrations were measured on the first two post-operative days. Results: There was no difference in morphine consumption or in any other outcome measure between the groups. Serum lidocaine concentrations increased during the study, with a maximum of 5.9 mg.l-1. There were no adverse events as a consequence of the study. Conclusion: Bilateral paravertebral infusion of lidocaine confers no advantage over systemic lidocaine infusion after cardiac surgery.

Acupressure effectively reduces the amount of nausea experienced, both in the first trimester of pregnancy, and after either opiates or cytotoxic agents. The aim of this randomised, controlled study was to establish whether it could also reduce any sensation of nausea related to the taking of maxillary dental impressions. The sample comprised 8 males and 14 females, with a mean age of 14.64 years and whose self-registration of nausea following an impression was greater than 33% of a 100mm visual analogue. The test involved a second impression with prior application of pressure on either PC.6, the sixth point on the Chinese pericardial meridian, or a placebo point on the forearm of the patient's dominant limb. A random mental choice as to which point to press was made by each patient, and double blind conditions prevailed. After the withdrawal of the impression, another visual analogue was marked. Of the 9 patients who had used the placebo point during the test impression, there had been a mean reduction of 29% in the scale of nausea experienced. Of the 13 who had used the PC.6 acupressure point, the mean reduction was 30%. The difference was not significant. Three and a half minutes of acupressure on PC.6 did not reduce the sensation of nausea induced by tactile stimulation of the soft palate in this small sample of susceptible patients.

Objectives. We aimed at evaluating both the efficacy and safety of TJ-54 (Yokukansan) in patients with treatment-resistant schizophrenia. This randomized, multicenter, double-blind, placebo-controlled study was conducted.Methods. One hundred and twenty antipsychotic-treated inpatients were included. Patients were randomized to adjuvant treatment with TJ-54 or placebo. During a 4-week follow-up, psychopathology was assessed using the Positive and Negative Syndrome Scale (PANSS).Results. TJ-54 showed a tendency of being superior to placebo in reduction total, positive, and general PANSS scores in treatment-resistant schizophrenia, but the difference was not statistically significant in both per-protocol set (PPS) and intention-to-treat (ITT). However, in PPS analysis, compared to the placebo group, the TJ-54 group showed statistically significant improvements in the individual PANSS subscale scores for lack of spontaneity and flow of conversation (TJ-54:−0.23±0.08; placebo:−0.03±0.08,P<0.018), tension (TJ-54:−0.42±0.09; placebo:−0.18±0.09,P<0.045), and poor impulse control (TJ-54:−0.39±0.10; placebo:−0.07±0.10,P<0.037).Conclusions. The results of the present study indicate that TJ-54 showed a tendency of being superior to placebo in reduction PANSS scores in treatment-resistant schizophrenia, but the difference was not statistically significant. However, compared to the placebo group, TJ-54 group showed statistically significant improvements in the individual PANSS subscale scores.
