Chronic elbow pain can be osseous, soft tissue, cartilaginous, and nerve related in etiology. Imaging plays an important role in differentiating between these causes of chronic elbow pain. This document provides recommendations for imaging of chronic elbow pain in adult patients. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer-reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which peer-reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Fibromyalgia syndrome (FMS) is a common widespread primary pain condition, with a worldwide prevalence of 2%-4%. Recent research has revealed important evidence for changes in central and peripheral nervous system functions and immunological activity. The diagnosis of FMS can be challenging with no known clinical laboratory investigations to confirm or refute its presence. Symptoms are commonly multiple, fluctuant and may not easily align with established medical diagnostic categories. It can be difficult for patients to articulate their array of symptoms, and for both patients and healthcare professionals to fully make sense of the complexities of the condition. As such, patients may be diagnosed inaccurately with alternative conditions, delaying diagnosis by years. The recent publication of the Royal College of Physicians' guidance aims to support clinicians in the diagnosis of FMS. Its purpose is to provide succinct, relevant information for patients and clinicians about FMS and its diagnosis.

The recent integration of regional anesthesia techniques into the cardiac surgical patient population has become a component of enhanced recovery after cardiac surgery pathways. Fascial planes of the chest wall enable single-injection or catheter-based infusions to spread local anesthetic over multiple levels of innervation. Although median sternotomy remains a common approach to cardiac surgery, minimally invasive techniques have integrated additional methods of performing cardiac surgery. Understanding the surgical approach and chest wall innervation is crucial to success in choosing the appropriate chest wall block. Parasternal intercostal plane techniques (previously termed "pectointercostal fascial plane" and "transversus thoracic muscle plane") provide anterior chest and ipsilateral sternal coverage. Anterolateral chest wall coverage is feasible with the interpectoral plane and pectoserratus plane blocks (previously termed "pectoralis") and superficial and deep serratus anterior plane blocks. The erector spinae plane block provides extensive coverage of the ipsilateral chest wall. Any of these techniques has the potential to provide bilateral chest wall analgesia. The relative novelty of these techniques requires ongoing research to be strategic, thoughtful, and focused on clinically meaningful outcomes to enable widespread evidence-based implementation. This review article discusses the key perspectives for performing and assessing chest wall blocks in a cardiac surgical population.

As an important member of ion channels family, the voltage-gated sodium channel (VGSC/Na) is associated with a variety of diseases, including epilepsy, migraine, ataxia, etc., and has always been a hot target for drug design and discovery. Many subtype-selective modulators targeting VGSCs have been reported, and some of them have been approved for clinical applications. However, the drug design resources related to VGSCs are insufficient, especially the lack of accurate and extensive compound data toward VGSCs. To fulfill this demand, we develop the Voltage-gated Sodium Channels Database (VGSC-DB). VGSC-DB is the first open-source database for VGSCs, which provides open access to 6055 data records, including 3396 compounds from 173 references toward nine subtypes of Nas (Na1.1 ~ Na1.9). A total of 28 items of information is included in each data record, including the chemical structure, biological activity (IC/EC), target, binding site, organism, chemical and physical properties, etc. VGSC-DB collects the data from small-molecule compounds, toxins and various derivatives. Users can search the information of compounds by text or structure, and the advanced search function is also supported to realize batch query. VGSC-DB is freely accessible at http://cadd.zju.edu.cn/vgsc/ , and all the data can be downloaded in XLSX/SDF file formats.
