Review
We here review behavioral, neuroimaging and electrophysiological studies of hypnosis as a state, as well as hypnosis as a tool to modulate brain responses to painful stimulations. Studies have shown that hypnotic processes modify internal (self awareness) as well as external (environmental awareness) brain networks. Brain mechanisms underlying the modulation of pain perception under hypnotic conditions involve cortical as well as subcortical areas including anterior cingulate and prefrontal cortices, basal ganglia and thalami. Combined with local anesthesia and conscious sedation in patients undergoing surgery, hypnosis is associated with improved peri- and postoperative comfort of patients and surgeons. Finally, hypnosis can be considered as a useful analogue for simulating conversion and dissociation symptoms in healthy subjects, permitting better characterization of these challenging disorders by producing clinically similar experiences.

Meta-Analysis
OBJECTIVES
National guidelines for the management of irritable bowel syndrome (IBS) recommend that psychological therapies should be considered, but their relative efficacy is unknown, because there have been few head-to-head trials. We performed a systematic review and network meta-analysis to try to resolve this uncertainty.
DESIGN
We searched the medical literature through January 2020 for randomised controlled trials (RCTs) assessing efficacy of psychological therapies for adults with IBS, compared with each other, or a control intervention. Trials reported a dichotomous assessment of symptom status after completion of therapy. We pooled data using a random effects model. Efficacy was reported as a pooled relative risk (RR) of remaining symptomatic, with a 95% CI to summarise efficacy of each comparison tested, and ranked by therapy according to P score.
RESULTS
We identified 41 eligible RCTs, containing 4072 participants. After completion of therapy, the psychological interventions with the largest numbers of trials, and patients recruited, demonstrating efficacy included self-administered or minimal contact cognitive behavioural therapy (CBT) (RR 0.61; 95% CI 0.45 to 0.83, P score 0.66), face-to-face CBT (RR 0.62; 95% CI 0.48 to 0.80, P score 0.65) and gut-directed hypnotherapy (RR 0.67; 95% CI 0.49 to 0.91, P score 0.57). After completion of therapy, among trials recruiting only patients with refractory symptoms, group CBT and gut-directed hypnotherapy were more efficacious than either education and/or support or routine care, and CBT via the telephone, contingency management, CBT via the internet and dynamic psychotherapy were all superior to routine care. Risk of bias of trials was high, with evidence of funnel plot asymmetry; the efficacy of psychological therapies is therefore likely to have been overestimated.
CONCLUSIONS
Several psychological therapies are efficacious for IBS, although none were superior to another. CBT-based interventions and gut-directed hypnotherapy had the largest evidence base and were the most efficacious long term.

Review
Hypnosis has a long history of use for anesthesia and pain management, as well as in assisting patient to prepare for medical procedures. This article reviews the history of hypnosis applications in clinical medicine and dentistry. Research on hypnotic susceptibility or hypnotic ability shows that the ability to respond effectively to hypnosis is a relatively stable trait, partially heritable, and measurable by means of several standard procedures. Persons low in hypnotic ability may benefit from alternative therapeutic interventions; however, the majority of medical patients will benefit from the integration of adjunctive hypnotic therapies into their medical and dental care. The article closes with a discussion of the stronger evidence-based applications of hypnosis in healthcare, and the need for well-trained certified hypnosis practitioners.

Randomized Controlled Trial
Poor sleep is one of the most frequent health concerns among menopausal women. All stages of sleep can be impacted by the menopause transition. Negative outcomes of poor sleep are multidimensional and include poor physical, psychological, cognition, and social outcomes. Hypnosis is a nonpharmacological treatment for poor sleep and hot flashes in menopausal women. The goal of hypnosis is to educate and train subjects to perform self-hypnosis to alleviate the underlying symptom. The use of hypnosis as a treatment for poor sleep has shown benefits for both acute and chronic insomnia. Initial findings from the National Center for Complementary and Integrative Health (NCCIH) Hypnosis Intervention for Sleep in Menopause: Examination of Optimal Dose and Method of Delivery randomized control trial of 90 women were presented. Results showed that program and treatment satisfaction were high in all groups, adherence to daily practice met or exceeded adherence benchmarks. There were significant reduction of poor sleep quality in all groups with a significant increase in minutes slept in all groups. The majority of women also showed clinical improvements of duration. There were clinically meaningful improvements in reducing the perception of poor sleep quality in 50%-77% of women across time. Overall, the use of self-hypnosis as a treatment program for sleep problems related to menopause was acceptable for women. Data further support that hypnosis is a promising technique to improve sleep in menopausal women with sleep and hot flashes. Further research is ongoing on self-hypnosis delivery and implementation into wider populations of women using clear definition and control groups.

Meta-Analysis Review
BACKGROUND
This review is one in a series of Cochrane reviews investigating pain management for childbirth. These reviews all contribute to an overview of systematic reviews of pain management for women in labour, and share a generic protocol. This review updates an earlier version of the review of the same title.
OBJECTIVES
To examine the effectiveness and safety of hypnosis for pain management during labour and childbirth.
SEARCH METHODS
We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2015) and the reference lists of primary studies and review articles.
SELECTION CRITERIA
Randomised controlled trials (RCTs) and quasi-RCTS comparing preparation for labour using hypnosis and/or use of hypnosis during labour, with or without concurrent use of pharmacological or non-pharmacological pain relief methods versus placebo, no treatment or any analgesic drug or technique.
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted data and assessed trial quality. Where possible we contacted study authors seeking additional information about data and methodology.
MAIN RESULTS
We included nine trials randomising a total of 2954 women. The risk of bias in trials was variable, there were several well-designed large trials and some trials where little was reported about trial design. Although eight of the nine trials assessed antenatal hypnotherapy, there were considerable differences between these trials in timing and technique. One trial provided hypnotherapy during labour. In this updated review we compared hypnosis interventions with all control groups (main comparison) and also with specific control conditions: standard care (nine RCTs), supportive counselling (two RCTs) and relaxation training (two RCTs).In the main comparison, women in the hypnosis group were less likely to use pharmacological pain relief or analgesia than those in the control groups, (average risk ratio (RR) 0.73, 95% CI 0.57 to 0.94, eight studies, 2916 women; very low-quality evidence; random-effects model). There were no clear differences between women in the hypnosis group and those in the control groups for most of the other primary outcomes. There were no clear differences for sense of coping with labour (MD 0.22, 95% CI -0.14 to 0.58, one study, 420 women; low-quality evidence) or spontaneous vaginal birth (average RR 1.12, 95% CI 0.96 to 1.32, six studies, 2361 women; low-quality evidence; random-effects model). There were no clear differences for satisfaction with pain relief (measured on a seven-point scale two weeks postnatally) for women in the hypnosis group who also received pethidine (MD 0.41, 95% CI -0.45 to 1.27; one study, 72 women), Entonox (MD 0.19, 95% CI -0.19 to 0.57; one study, 357 women), self-hypnosis (MD 0.28, 95% CI -0.32 to 0.88; one study, 160 women), or epidural (MD -0.03, 95% CI -0.40 to 0.34; one study, 127 women), but a slight benefit in favour of hypnosis was seen for women who received water immersion (MD 0.52, 95% CI 0.04 to 1.00; one study, 174 women (all low-quality evidence). There were no clear differences for satisfaction with pain relief when it was measured as the number of women who reported they had adequate pain relief (risk ratio (RR) 1.06, 95% confidence interval (CI) 0.94 to 1.20, one study, 264 women; low-quality evidence). It should be noted that for pharmacological pain relief and spontaneous vaginal birth, there was evidence of considerable statistical heterogeneity, which could not be fully explained by subgroup analysis.For this review's secondary outcomes, no clear differences were found between women in the hypnosis group and women in the control groups for most outcomes where data were available. There was mixed evidence regarding benefits for women in the hypnosis group compared with all control groups for pain intensity, satisfaction with childbirth experience and postnatal depression. For each of these outcomes, data from more than one trial were available for analysis but could not be combined due to differences in measurement methods. There was evidence that fewer women in the hypnosis group stayed in hospital for more than two days after the birth but this finding was based on one small study (RR 0.11, 95% CI 0.02 to 0.83). No clear differences between women in the hypnosis group and the control groups were found for the other secondary outcomes where data were available.In the comparisons of hypnosis with specific types of control conditions: standard care, supportive counselling and relaxation training, there were no clear differences found between women in the hypnosis group and those in the standard care control groups or the relaxation control groups for the primary outcomes. Compared with the women in the supportive counselling control group, women in the hypnosis group were less likely to use pharmacological analgesia (average RR 0.48, 95% CI 0.32 to 0.73, two studies, 562 women). They were also more likely to have a spontaneous vaginal birth (RR 2.42, 95% CI 1.43 to 4.07), although this finding was based on the results of one small study. Overall these new comparisons displayed much less statistical heterogeneity than the comparison including all control groups.
AUTHORS' CONCLUSIONS
There are still only a relatively small number of studies assessing the use of hypnosis for labour and childbirth. Hypnosis may reduce the overall use of analgesia during labour, but not epidural use. No clear differences were found between women in the hypnosis group and those in the control groups for satisfaction with pain relief, sense of coping with labour or spontaneous vaginal birth. Not enough evidence currently exists regarding satisfaction with pain relief or sense of coping with labour and we would encourage any future research to prioritise the measurement of these outcomes. The evidence for the main comparison was assessed using GRADE as being of low quality for all the primary outcomes with downgrading decisions due to concerns regarding inconsistency of the evidence, limitations in design and imprecision. Further research is needed in the form of large, well-designed randomised controlled trials to assess whether hypnosis is of value for pain management during labour and childbirth.

AIM
Patient compliance is of paramount importance for proper dental treatment, which can be difficult to achieve in children due to anxiety and fear, hindering the therapeutic procedure. In addition to well-known sedation methods (pharmacological and nitrous oxide), further methods of approach are being tested, such as hypnotherapy.
MATERIALS
The sample consisted of 150 children (90 males, 60 females). Paper questionnaires, frequency meter, nitrous oxide dispenser in association with the use of the television were exploited. At the end of treatment, subjective pain was assessed using the VAS scale, while objective pain was assessed using the FLACC scale and heart rate. This made it possible to compare two experimental groups, one treated with nitrous oxide, and the other with hypnotherapy. The control group was treated with classic behavioural approach techniques. The results obtained were analysed by SPSS Software (Statistical Package for Social Science, version 27) and the inferences between the results were calculated for confirmation.
CONCLUSION
Hypnotherapy can be a valid substitute for nitrous oxide in paediatric dentistry.

Randomized Controlled Trial
BACKGROUND
Different non-pharmacological techniques, including hypnosis and virtual reality (VR) are currently used as complementary tools in the treatment of anxiety, acute and chronic pain. A new technique called virtual reality hypnosis (VRH), which encompasses a combination of both tools, is regularly used although its benefits and underlying mechanisms remain unknown to date. With the goal to improve our understanding of VRH combination effects, it is necessary to conduct randomised and controlled research trials in order to understand their clinical interest and potential benefits.
METHODS
Patients (n = 100) undergoing cardiac surgery at the Liège University Hospital will be randomly assigned to one of four conditions (control, hypnosis, VR or VRH). Each patient will receive two sessions of one of the techniques: one the day before the surgery and one the day after. Physiological assessments will be made on the monitor and patients will rate their levels of anxiety, fatigue, pain, absorption and dissociation.
DISCUSSION
This study will help to expand knowledge on the application of virtual reality, hypnosis and VRH in the specific context of cardiac and intensive care procedures, and the influence of these non-pharmacological techniques on patient's anxiety, fatigue, pain and phenomenological experience.

Review
INTRODUCTION
Hypnotherapy is increasingly used in general medicine in France to manage health problems such as insomnia. There is some evidence to support the efficacy of hypnosis in treating insomnia but this evidence is based on methodologies of various strengths. This review aims to explore the methodological elements employed in hypnotherapy research to manage insomnia.
METHOD
We performed a narrative review of the literature using systematic review methods focusing on treating insomnia with hypnosis. PubMed, Psycinfo, BASE and Cochrane databases and Google scholar were searched.
RESULTS
Overall, 25 studies were included consisting of 10 case studies, 11 randomised, controlled trials and 4 pre and post intervention studies. The study designs, intervention, control and comparators were heterogeneous, as were the hypnosis definitions and techniques. Also, detailed descriptions of the hypnosis techniques were lacking. Most studies used non-quantifiable measurement criteria and sample numbers were too small to show significance or be representative. No double-blind study was found.
CONCLUSION
Our results indicate that the current research concerning the efficacy of hypnosis to relieve insomnia is lacking in key methodological elements. The evaluation research process requires robust methodology. We propose applying the IDEAL framework, which recommends research steps to evaluate non-pharmacological and other complex therapies to evaluate the efficacy of hypnosis to manage insomnia.

Review
INTRODUCTION
Nocturnal enuresis affects 15% to 20% of 5-year-old children, 5% of 10-year-old children, and 1% to 2% of people aged 15 years and over. Without treatment, 15% of affected children will become dry each year. Nocturnal enuresis is not diagnosed in children younger than 5 years, and treatment may be inappropriate for children younger than 7 years.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of interventions for relief of symptoms? We searched: Medline, Embase, The Cochrane Library, and other important databases up to February 2010 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 19 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: acupuncture, anticholinergics (oxybutynin, tolterodine, hyoscyamine), desmopressin, dry bed training, enuresis alarm, hypnotherapy, standard home alarm clock, and tricyclics (imipramine, desipramine).

Review
Studies conducted in healthy subjects have clearly shown that different hypnotic susceptibility, which is measured by scales, is associated with different functional equivalence between imagery and perception/action (FE), cortical excitability, and information processing. Of note, physiological differences among individuals with high (highs), medium (mediums), and low hypnotizability scores (lows) have been observed in the ordinary state of consciousness, thus independently from the induction of the hypnotic state, and in the absence of specific suggestions. The potential role of hypnotic assessment and its relevance to neurological diseases have not been fully explored. While current knowledge and therapies allow a better survival rate, there is a constant need to optimize rehabilitation treatments and quality of life. The aim of this paper is to provide an overview of hypnotizability-related features and, specifically, to discuss the hypothesis that the stronger FE, the different mode of information processing, and the greater proneness to control pain and the activity of the immune system observed in individuals with medium-to-high hypnotizability scores have potential applications to neurology. Current evidence of the outcome of treatments based on hypnotic induction and suggestions administration is not consistent, mainly owing to the small sample size in clinical trials and inadequate control groups. We propose that hypnotic assessment may be feasible in clinical routine and give additional cues into the treatment and rehabilitation of neurological diseases.
