A growing number of adolescents are being diagnosed with acute myocarditis following mRNA COVID-19 vaccinations. This case describes an adolescent who presented to the emergency department with chest pain and tachycardia following the Pfizer-BioNTech COVID-19 vaccination. Point-of-care ultrasound was performed prior to the return of laboratory studies and revealed depressed left ventricular systolic function. Point-of-care ultrasound may be a tool used to rapidly diagnose or risk stratify patients with potential post-COVID-19 vaccine myocarditis.

Chronic postsurgical pain (CPSP) affects an estimated 10% to 50% of adults depending on the type of surgical procedure. Clinical prediction models can help clinicians target preventive strategies towards patients at high risk for CPSP. Therefore, the objective of this systematic review was to identify and describe existing prediction models for CPSP in adults. ⋯ The most common predictors identified in final prediction models included preoperative pain in the surgical area, preoperative pain in other areas, age, sex or gender, and acute postsurgical pain. Clinical prediction models may support prevention and management of CPSP, but existing models are at high risk of bias that affects their reliability to inform practice and generalizability to wider populations. Adherence to standardized guidelines for clinical prediction model development is necessary to derive a prediction model of value to clinicians.

Prior research has shown that Open Label Placebos (OLPs; that is, placebos described honestly as inactive pills) are effective for a variety of clinical conditions, including pain. However, little is known about patient attitudes towards OLPs. We conducted qualitative interviews with n = 11 patients (73% female) who recently had hand or wrist surgery and took ≥ 1 opioid pill. ⋯ Results suggest that OLPs appear to be well received as a postoperative pain treatment among the patients in this study. PERSPECTIVE: This qualitative study examines how hand surgery patients view OLPs, which are placebos described honestly as inactive pills. OLPs were generally well received by patients as a treatment for pain after surgery and could be considered as an adjunctive treatment to potentially reduce reliance on prescription opioids.

Comparative StudyAcute Visceral Pain in Rats: Vagal Nerve Block Compared to Bupivacaine Administered Intramuscularly.
Visceral and parietal peritoneum layers have different sensory innervations. Most visceral peritoneum sensory information is conveyed via the vagus nerve to the nucleus of the solitary tract (NTS). We already showed in animal models that intramuscular (i.m.) injection of local anesthetics decreases acute somatic and visceral pain and general inflammation induced by aseptic peritonitis. The goal of the study was to compare the effects of parietal block, i.m. bupivacaine, and vagotomy on spinal cord and NTS stimulation induced by a chemical peritonitis. ⋯ In rats receiving intraperitoneal carrageenan, i.m. bupivacaine similarly inhibited c-Fos and microglial activation both in cord and in the NTS. Vagal block inhibited activation only in the NTS. Our study underlines the role of the vagus nerve in the transmission of an acute visceral pain message and confirmed that systemic bupivacaine prevents noxious stimuli. This emphasizes the effects of systemic local anesthetics on inflammation and visceral pain.
