Auricular acupuncture can be an effective treatment for acute anxiety, but there is a lack of direct comparisons of acupuncture to proven standard drug treatments. In this study we compared the efficacy of auricular acupuncture with intranasal midazolam, placebo acupuncture, and no treatment for reducing dental anxiety. Patients having dental extractions (n = 67) were randomized to (i) auricular acupuncture, (ii) placebo acupuncture, and (iii) intranasal midazolam and compared with a no treatment group. Anxiety was assessed before the interventions, at 30 min, and after the dental extraction. Physiological variables were assessed continuously. With the no treatment group as control, the auricular acupuncture group, and the midazolam group were significantly less anxious at 30 min as compared with patients in the placebo acupuncture group (Spielberger Stait-Trait Anxiety Inventory X1, P = 0.012 and <0.001, respectively). In addition, patient compliance assessed by the dentist was significantly improved if auricular acupuncture or application of intranasal midazolam had been performed (P = 0.032 and 0.049, respectively). In conclusion, both, auricular acupuncture and intranasal midazolam were similarly effective for the treatment of dental anxiety. The present study examines the usefulness of acupuncture as an aid to stopping smoking. Results from 405 subjects show acupuncture can help between 5 and 15 percent of the population to stop smoking for at least six months. Using chronically implanted press needles, previously reported 'effective' auricular acupuncture points for smoking cessation are shown to be no better than 'placebo' auricular points. Additional electroacupuncture on the hand neither increases the probability of stopping smoking nor enhances the reduction in smoking at three week, three month or six month follow-up periods. It is therefore likely that a large psychological component is attached to acupuncture to stop people smoking. During the last 30 years, auricular acupuncture has been used as complementary treatment of cancer pain when analgesic drugs do not suffice. The purpose of this study is to examine the efficacy of auricular acupuncture in decreasing pain intensity in cancer patients.
                Ninety patients were randomly divided in three groups; one group received two courses of auricular acupuncture at points where an electrodermal signal had been detected, and two placebo groups received auricular acupuncture at points with no electrodermal signal (placebo points) and one with auricular seeds fixed at placebo points. Patients had to be in pain, attaining a visual analog score (VAS) of 30 mm or more after having received analgesic treatment adapted to both intensity and type of pain, for at least 1 month of therapy. Treatment efficacy was based on the absolute decrease in pain intensity measured 2 months after randomization using the VAS.
                The main outcome was pain assessed at 2 months, with the assessment at 1 month carried over to 2 months for the eight patients who interrupted treatment after 1 month. For three patients, no data were available because they withdrew from the study during the first month. Pain intensity decreased by 36% at 2 months from baseline in the group receiving acupuncture; there was little change for patients receiving placebo (2%). The difference between groups was statistically significant (P <.0001).
                The observed reduction in pain intensity measured on the VAS represents a clear benefit from auricular acupuncture for these cancer patients who are in pain, despite stable analgesic treatment. The purpose of this study was to determine whether parental auricular acupuncture reduces parental preoperative anxiety and thus allows children to benefit from parental presence during induction of anesthesia.
                Mothers of children who were scheduled to undergo surgery were randomly assigned to an acupuncture intervention group (auricular press needles at relaxation, tranquilizer point, and master cerebral point) or a sham acupuncture control group (auricular press needles at the shoulder, wrist, and extraneous auricular point). The intervention was performed at least 30 min before the child's induction of anesthesia. All mothers were present during induction of anesthesia. The behavioral and physiologic anxiety of mothers and children were rated during the perioperative process.
                : Multivariable analysis examining maternal anxiety as a function of group found a group-by-time interaction (F1,65 = 4.1, P = 0.04). That is, after induction, maternal anxiety in the acupuncture group was significantly lower (42.9 +/- 10 vs. 49.5 +/- 11; P = 0.014). A multivariate model (F1,65 = 4.8, P =0.031) also showed that children whose mothers received the acupuncture intervention were significantly less anxious on entrance to the operating room (34.9 +/- 20 vs. 47.4 +/- 26; P = 0.03) and during introduction of the anesthesia mask (38.6 +/- 25 vs. 55.6 +/- 31; P = 0.016). There were no significant differences in maternal blood pressure and heart rate between the two groups.
                : Auricular acupuncture significantly decreased maternal anxiety during the preoperative period. Children of mothers who underwent acupuncture intervention benefitted from the reduction of maternal anxiety during the induction of anesthesia. Acupuncture or acupressure at the Nei-Guan (P.6) point on the wrist produces antiemetic effects in awake but not anesthetized patients. The authors studied whether a combined approach using preoperative acupressure and intra- and postoperative acupuncture can prevent emesis following tonsillectomy in children.
                Patients 2-12 yr of age were randomly assigned to study or placebo groups. Two Acubands with (study) and two without (placebo) spherical beads were applied bilaterally on the P.6 points; non-bead- and bead-containing Acubands, respectively, were applied on the sham points. All Acubands were applied before any drug administration. After anesthetic induction, acupuncture needles were substituted for the beads and remained in situ until the next day. All points were covered with opaque tape to prevent study group identification. A uniform anesthetic technique was used; postoperative pain was managed initially with morphine and later with acetaminophen and codeine. Emesis, defined as retching or vomiting, was assessed postoperatively. Ondansetron was administered only after two emetic episodes at least 2 min apart. Droperidol was added if emesis persisted.
                One hundred patients were enrolled in the study. There were no differences in age, weight, follow-up duration, or perioperative opioid administration between groups. Retching occurred in 26% of the study patients and in 28% of the placebo patients; 51 and 55%, respectively, vomited; and 60 and 59%, respectively, did either. There were no significant differences between the groups. Redness occurred in 8.5% of acupuncture sites.
                Perioperative acupressure and acupuncture did not diminish emesis in children following tonsillectomy. To evaluate the efficacy and safety of topical atropine, a nonselective muscarinic antagonist, in slowing the progression of myopia and ocular axial elongation in Asian children.
                Parallel-group, placebo-controlled, randomized, double-masked study.
                Four hundred children aged 6 to 12 years with refractive error of spherical equivalent -1.00 to -6.00 diopters (D) and astigmatism of -1.50 D or less.
                Participants were assigned with equal probability to receive either 1% atropine or vehicle eye drops once nightly for 2 years. Only 1 eye of each subject was chosen through randomization for treatment.
                The main efficacy outcome measures were change in spherical equivalent refraction as measured by cycloplegic autorefraction and change in ocular axial length as measured by ultrasonography. The primary safety outcome measure was the occurrence of adverse events.
                Three hundred forty-six (86.5%) children completed the 2-year study. After 2 years, the mean progression of myopia and of axial elongation in the placebo-treated control eyes was -1.20+/-0.69 D and 0.38+/-0.38 mm, respectively. In the atropine-treated eyes, myopia progression was only -0.28+/-0.92 D, whereas the axial length remained essentially unchanged compared with baseline (-0.02+/-0.35 mm). The differences in myopia progression and axial elongation between the 2 groups were -0.92 D (95% confidence interval, -1.10 to -0.77 D; P<0.001) and 0.40 mm (95% confidence interval, 0.35-0.45 mm; P<0.001), respectively. No serious adverse events related to atropine were reported.
                Topical atropine was well tolerated and effective in slowing the progression of low and moderate myopia and ocular axial elongation in Asian children. We conducted a 6-week, single-blind study of acupuncture for cocaine dependence in methadone-maintained patients (N = 40) for the purpose of identifying an appropriate needle puncture control for use in future large-scale clinical trials. Patients were randomly assigned to receive daily acupuncture in three auricular sites plus one body site (LI-4), or in control sites within 2-3 mm of the four active sites. Overall, there was a positive response to treatment on a variety of drug-related and psychosocial measures. Cocaine use decreased significantly for patients in both needle puncture groups. The only statistically significant difference between the two types of needle puncture was on ratings of craving. Subjects rated each type of needle puncture as equally credible and perceived no significant differences on the acute effects of the two types of needle insertions. Power calculations based on these findings suggest that very large sample sizes would be required to detect treatment differences between this control condition and active acupuncture. Alternative controls are suggested, and the challenges inherent in implementing controlled clinical trials of acupuncture are discussed. This study was designed to compare the reduction in myopia progression in patients treated with atropine eyedrops alone with patients treated with a combined treatment of atropine and stimulation of the auricular acupoints.
                This study was a randomized single-blind clinical controlled trial. A total of 71 school-aged children with myopia, who fulfilled the eligibility criteria, were recruited. They were randomly assigned into three groups. These were 22 treated with the 0.25% atropine (0.25A) only, 23 treated with the 0.5% atropine (0.5A) only and 26 treated with 0.25% atropine together with stimulation of the auricular acupoints (0.25A+E). The differences in the post-treatment effects among these three groups were statistically assessed. The primary outcome parameter was myopia progression, which was defined as diopter change per year (D/Y) after cycloplegic refraction measurement.
                The mean myopia progression of the 0.25A group was 0.38+/-0.32 D/Y. No significant difference in mean myopia progression was found between the 0.5A (0.15+/-0.15 D/Y) and 0.25A+E (0.21+/-0.23 D/Y) groups. However, there was a markedly reduced myopia progression in the 0.25A+E group compared to the 0.25A group (p<0.05). Furthermore, there was no statistical difference among these three groups in axial length elongation (ALE) of eye during this stage of the investigation.
                This study demonstrates that there was efficacy in stimulating the auricular acupoints and this enhanced the action of 0.25% atropine as a means of myopia control. The result was an effect almost equal to that of 0.5% atropine alone. There is also a need that the ALE of the eye should be further investigated over a longer period using the combined therapy. The purpose of this study was to replicate a previous study to determine the effectiveness of acupuncture-like transcutaneous electrical nerve stimulation in treating primary dysmenorrhea. Twenty-one women with dysmenorrhea received a placebo pill or 30 minutes of acupuncture-like TENS. All subjects completed two pain questionnaires before treatment; immediately posttreatment; 30, 60, 120, and 180 minutes posttreatment; and the next morning upon awakening. Each woman also participated in a separate study measuring electrical resistance at four auricular acupuncture points before and immediately after treatment. The data were analyzed with a two-factor repeated-measures analysis of variance, which revealed statistical significance over time but not for group or interaction between group and time. Results revealed an average pain relief of at least 50% immediately posttreatment, indicating that acupuncture-like TENS may be useful for dysmenorrheic pain. This study also suggests that auriculotherapy via acupressure may relieve the pain of primary dysmenorrhea. The management of disabling breathlessness is poor, and a standardized form of acupuncture has been reported as offering benefit. This study was designed to evaluate the efficacy of standardized acupuncture treatment.
                A single-blind, randomized, crossover study.
                This study was carried out on a domiciliary basis in Southampton (UK).
                This study evaluated a standardized acupuncture technique vs an appropriately validated placebo/control (mock transcutaneous electrical nerve stimulation [TENS]) for disabling, nonmalignant breathlessness (largely COPD). The acupuncture was provided by an appropriately trained nurse acupuncturist. Each patient received six treatments in each phase of the study, with an intervening 2-week washout period.
                The primary outcome was worst breathlessness (visual analog scale, 0 to 100 mm), with the sample size based on an 80% power to detect a 10-mm difference between treatment means. Secondary outcomes included the St George's respiratory questionnaire score and treatment credibility.
                Thirty-six patients were entered into the study (33 with COPD), and 24 patients completed both treatment phases. The primary outcome improved significantly during the course of the study, but there were no significant treatment differences between acupuncture and the placebo/control of mock TENS for either primary or secondary outcomes. The placebo was shown to be a credible control. There was no evidence of a carryover effect from the first to second phase of the study.
                This standardized acupuncture technique does not show specific efficacy in disabling nonmalignant breathlessness, but those entered into the study did experience clinically significant benefit from both treatments. The evidence on the effectiveness of acupuncture for irritable bowel syndrome (IBS) is inconclusive. However, many patients with IBS are self referring for acupuncture, therefore it is of interest to know whether acupuncture is effective or not. The aim of this study was to establish variability in the primary outcome measure to enable a sample size to be calculated for a full scale trial, and to explore feasibility and design criteria.
                A pragmatic randomised controlled trial compared 10 sessions of acupuncture plus usual GP care with usual GP care alone. Thirty patients were recruited from four GP databases in Birmingham, UK, and randomised one-to-two to acupuncture or usual care alone. The primary outcome was the IBS Symptom Severity Score (SSS) at three months (maximum score 500). Analysis was by intention-to-treat, and multiple imputation was used for missing data.
                From the databases, 189 patients with IBS were identified, of whom 30 were eligible and consented to randomisation. At three months, a statistically and clinically significant difference between groups of 138 points (SD 90) in favour of acupuncture was observed on the IBS SSS (95% CI: 66 to 210; P=0.001) using multiple imputation. For a full scale trial, we estimate that a sample size of 108 patients per arm is required, based on a minimum clinically significant change of 50 points, drawn from a primary care population of 140 000.
                We established the feasibility of a full scale trial, successfully recruiting patients and calculating the sample size required. The results of our pilot analysis suggest that more definitive research into acupuncture for IBS is merited. A pragmatic trial design will not be able to distinguish between acupuncture specific effects and placebo effects; however, it is the design of choice to determine cost effectiveness.
Two trials are included in this review but no conclusions can be drawn for the benefit of co-acupressure for slowing progress of myopia in children. Further evidence in the form of RCTs are needed before any recommendations can be made for the use of acupuncture treatment in clinical use. These trials should compare acupuncture to placebo and have large sample sizes. Other types of acupuncture (such as auricular acupuncture) should be explored further as well as compliance with treatment for at least six months or longer. Axial length elongation of the eye should be investigated for at least one year. The potential to reduce/eliminate pain from acupuncture experienced by children should also be reviewed.
