Impact of Pain From Injectables Antiretroviral Treatments in HIV-1 Patients Based on the Injection Site (Ventrogluteal or Dorsogluteal) and the Use or Non-use of Virtual Reality Headset

This is a multicenter, randomized, open-label study with a cross-over design. The objective of this project is to compare the intensity of pain induced by injectable antiretroviral (ARV) treatment (Cabotegravir® and Rilpivirine®) in patients infected with HIV-1, depending on the injection site and whether or not they are wearing a virtual reality headset. The reference group being the dorsogluteal injection without headset. Participants who meet the study criteria will be randomized into 1 of 24 sequences. A sequence is composed by 4 injections procedures: dorsogluteal intramuscular injection (A), ventrogluteal intramuscular injection (B), dorsogluteal intramuscular injection with virtual reality headset (C), ventrogluteal intramuscular injection with virtual reality headset (D). Each patient will be their own witness and will experience the 4 intramuscular injection procedures of injectable antiretroviral. The study population are patients carrying HIV-1 and being monitored for this pathology, eligible (naïve patients) or already under Cabotegravir® (CAB) and Rilpivirine® (RPV) injectable treatment.

Clinical Trial Comparing Pain Perception in Children Using Two Different Local Anesthesia Tools

The goal of this clinical study is to learn whether the Super Pen (SP) device can reduce pain during local anesthesia (LA) infiltration for primary teeth compared to the conventional syringe (CS) in children aged 6-12 years. It will also explore factors that influence children's pain perception and their preferences for the anesthesia delivery method. The main questions this study aims to answer are: * Does the Super Pen (SP) reduce the pain experienced during LA infiltration compared to the conventional syringe (CS)? * How do factors such as age, sex, and arch treated (maxilla or mandible) influence children's pain perception when using the SP? * Which method-SP or CS-do children prefer during LA infiltration? Participants will: Receive local anesthesia using both the SP and CS techniques in a split-mouth design. Have their pain responses assessed using self-reported, behavioral, and physiological measures. Indicate their preference for either technique after both experiences.

Sweet-Tasting Solution Versus Placebo to Reduce Pain During Local Anesthetic Injection in Children

The goal of this clinical trial is to learn whether applying a sugar-free flavored sweet solution (SFSS) before local anesthesia helps reduce injection pain in children. The main question it aims to answer is: Does SFSS reduce pain during dental local anesthesia compared to a placebo (plain water)? Researchers will compare the use of SFSS and a placebo to see which results in lower pain scores. Participants will: Receive SFSS or placebo before local anesthesia during two dental visits Have their pain measured using self-reported and observational pain scales Have their heart rate monitored during the procedure
