IntroductionThere are no well-established biomedical treatments for the core symptoms of autism spectrum disorder (ASD). A small number of studies suggest that repetitive transcranial magnetic stimulation (rTMS), a non-invasive brain stimulation technique, may improve clinical and cognitive outcomes in ASD. We describe here the protocol for a funded multicentre randomised controlled clinical trial to investigate whether a course of rTMS to the right temporoparietal junction (rTPJ), which has demonstrated abnormal brain activation in ASD, can improve social communication in adolescents and young adults with ASD.Methods and analysisThis study will evaluate the safety and efficacy of a 4-week course of intermittent theta burst stimulation (iTBS, a variant of rTMS) in ASD. Participants meeting criteria for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition ASD (n=150, aged 14–40 years) will receive 20 sessions of either active iTBS (600 pulses) or sham iTBS (in which a sham coil mimics the sensation of iTBS, but no active stimulation is delivered) to the rTPJ. Participants will undergo a range of clinical, cognitive, epi/genetic, and neurophysiological assessments before and at multiple time points up to 6 months after iTBS. Safety will be assessed via a structured questionnaire and adverse event reporting. The study will be conducted from November 2020 to October 2024.Ethics and disseminationThe study was approved by the Human Research Ethics Committee of Monash Health (Melbourne, Australia) under Australia’s National Mutual Acceptance scheme. The trial will be conducted according to Good Clinical Practice, and findings will be written up for scholarly publication.Trial registration numberAustralian New Zealand Clinical Trials Registry (ACTRN12620000890932).

Incisor Hypomineralisation

IntroductionDentin hypersensitivity (DH) is defined as high sensitivity of the vital dentin when exposed to thermal, chemical or tactile stimuli. Two mechanisms are required for the occurrence of DH: (1) the dentin must be exposed and (2) the dentinal tubules must be open and connected to the pulp. Molar–incisor hypomineralisation (MIH) is a qualitative abnormality of a genetic origin that affects tooth enamel and, in most cases, is accompanied by DH. The control of tooth sensitivity is fundamental to the successful treatment of MIH. The aim of the proposed randomised, controlled, clinical trial is to evaluate the effectiveness of different protocols for the control of DH in patients with teeth affected by MIH.Methods and analysisOne hundred and forty patients who meet the inclusion criteria will be allocated to four groups. Group 1 will be the control group (placebo). In Group 2, sensitive teeth will be sealed with PermaSeal (Ultradent). In Group 3, sensitive teeth will receive low-level laser (LLL, AsGaAl) at a wavelength of 780 nm (Laser XT Therapy, DMC, São Carlos, Brazil). In Group 4, sensitive teeth will be treated with both LLL and PermaSeal (Ultradent). DH will be evaluated 15 min after the application of the treatments and the patients will be reevaluated 1 week, 1 month, 3 months and 6 months after the treatments. The primary outcome of this study is change in pain/sensitivity, when evaluated through a Visual Analogue Scale, to determine the effectiveness of the proposed treatments, as well as differences among the evaluation times for each proposed treatment.Ethics and disseminationThis protocol has been ethically approved by the local medical ethical committee (protocol number: 4.020.261). Results will be submitted to international peer-reviewed journals and presented at international conferences.Trial registration numberNCT04407702.

Standard Colonoscopy

Background and aims Adenoma detection rate (ADR) in colon cancer screening is most important for cancer prophylaxis. This work is the first three-armed randomised controlled clinical trial aimed at comparing a head-to-head setting standard colonoscopy (SC) with Endocuff-assisted colonoscopy (EC) and cap-assisted colonoscopy (CAC) for improvement of ADR. Methods Patients from Poland and Germany with independent indication for colonoscopy were randomised into three arms of this trial: EC, CAC and SC. Exclusion criteria were age <18 years, active Crohn’s disease or ulcerative colitis, known stenosis and post-colonic resection status. Results A total of 585 patients (195 SC, 189 EC and 186 CAC) were enrolled in this study. Indications were not different between the groups (colorectal cancer screening 51%, diagnostic colonoscopy in 31% and post polypectomy follow-up in 18%; p=0.94). Withdrawal time was a mean of seven minutes in all groups ( p=0.658), and bowel preparation did not differ between the groups. The time to reach the caecum was significantly reduced when using the cap (a mean of six minutes for CAC vs. seven minutes for SC; p=0.0001). There was no significant difference in the primary outcome of the ADR between the groups (EC 32%, CAC 30%, SC 30%; p=0.815). EC proved to be superior (EC vs. SC) in the sigmoid colon and transverse colon for polyp detection. Conclusion The use of EC increased the total number of polyps seen during colonoscopy. In contrast to recent studies, no significant improvement of the ADR was detected.
