The central mechanism of acupuncture for primary dysmenorrhea was explored by summarizing the changes in different regional networks of the brain induced by acupuncture stimulation by analyzing the existing studies. ⋯ The results suggest that the mechanism of acupuncture in the treatment of primary dysmenorrhea is the involvement of networks regulating different areas of the brain in the analgesic effects of acupuncture. The brain regions involved in primary dysmenorrhea acupuncture analgesia were mainly located in the pain matrix, default mode network, salience network, and limbic system.

Randomized Controlled Trial
Analgesic Efficacy of Ketoprofen Transdermal Patch versus Ibuprofen Oral Tablet on Postendodontic Pain in Patients with Irreversible Pulpitis: A Randomized Clinical Trial.
In this randomized clinical trial, 64 patients who had mandibular first and second molars with irreversible pulpitis were randomly divided into two groups (n = 32) by stratified permuted block randomization. The experimental group used 60 mg KTP every 6 hours, and the control group received 400 mg ibuprofen tablets every 6 hours for 1 day. The severity of pain experienced by patients was quantified before and at 2, 4, 8, 12, 24, and 48 hours after endodontic treatment, using the numerical rating scale (NRS). Data were analyzed by using the t-test, Mann-Whitney test, and generalized estimating equation (GEE) (alpha = 0.05). ⋯ Both KTP and ibuprofen effectively decreased postendodontic pain. Considering the comparable pattern of pain reduction, KTP can be used as an alternative to ibuprofen tablets for effective pain control after endodontic treatment of mandibular first and second molars with irreversible pulpitis.

In the percutaneous treatment of trigeminal neuralgia (TN), the difficulty in accessing the foramen ovale (FO) has been widely recognized. However, the most efficient percutaneous treatment target is the so-called trigeminal ganglion target (TGT). We propose that the TGT in a puncture can be identified by magnetic resonance diffusion tensor imaging (MR-DTI). ⋯ The characteristics of the TGT are correlated with the number of punctures in the PSR. The application of MR-DTI for detecting the size of the TGT is an important step in predicting the difficulty of puncture. The PSR approach can be guided by the TGT and FO for TN patients who present with multiple adverse factors and thus may be beneficial in reducing the number of complications.

Observational Study
A Novel Scale to Assess Parental Satisfaction of Dental Local Anesthetic Techniques in Children: A Cross-Sectional Study.
Pain control is one of the most important aspects that can affect parental satisfaction of the dental care provided for children. Dental local anesthesia has the highest impact on pain sensation of the children. However, there is no scale in the literature to assess parental satisfaction of dental local anesthetic techniques. ⋯ Findings of this study reported that the designed parental satisfaction of dental local anesthetic techniques scale (PSLAS) is a valid and reliable scale to be used. Moreover, this study showed that parental satisfaction was higher when computerized intraosseous anesthesia was used in comparison to inferior alveolar nerve block.

Due to the COVID-19 pandemic, healthcare centers quickly adapted services into virtual formats. Pain clinics in Canada play a vital role in helping people living with pain, and these clinics remained essential services for patients throughout the pandemic. This study aimed to (1) describe and compare the transition from in-person to virtual pain care services at Canadian pain clinics during the onset of the COVID-19 pandemic and (2) provide postpandemic recommendations for pain care services to optimize the quality of patient care. ⋯ Participating clinics were capable of transitioning pain care services to the virtual formats and have in-person care when needed with proper safety precautions. The pandemic demonstrated that it is feasible and sustainable for pain clinics to have a hybrid of virtual and in-person care to treat those living with pain. It is recommended that moving forward, there should be a hybrid of both virtual and in-person care for pain clinics. Ministries of Health should continue to develop policies and funding mechanisms that support innovations aimed at holistic healthcare, interdisciplinary teams, and the expansion of clinics' geographical reach for patient access.
