AI Article Synopsis
- The study aimed to investigate where pain sensitivity points are located on the body surface of patients with knee osteoarthritis (KOA).
- Researchers tested 916 KOA patients, probing 3,618 pain sensitivity points, finding that most points were sensitized and closely located to key acupoints.
- Results indicated that pain sensitivity points were primarily found around specific acupoints in the knee area, suggesting that their presence may be related to the severity of pain experienced, as measured by the McGill pain questionnaire.
Article Abstract
Objective: To observe the distribution characteristics and rules of pain sensitivity points on body surface in patients with knee osteoarthritis (KOA).
Methods: A total of 916 patients with KOA were selected in this study, the pain sensitivity points of local site of knee joint were probed by thumb palpation. Tape was used to measure the distance between the pain sensitivity points and the most nearby acupoints. The Wagner tenderness measuring instrument was used to measure the tenderness threshold of pain sensitivity points.
Results: A total of 3618 pain sensitivity points were probed, among them, 3338 pain sensitivity points were sensitized. The minimum sensitization degree was 1.00, the maximum sensitization degree was 3.39, while the average sensitization degree was (2.16±0.60). Pain sensitivity points were distributed 0.37-1.73 around the acupoints, the average distance was (1.26±0.20) . Most of the pain sensitivity points (48.7%) were around Yingu (KI 10), Ququan (LR 8) and Xuehai (SP 10). The number and sensitization degree of pain sensitivity points were associated with McGill pain questionnaire score of patients with KOA (<0.001).
Conclusion: The pain sensitivity points of patients with KOA may be the expansion effect of acupoint areas in the disease states, pain sensitivity points are more likely to appear on the medial side of knee joint.

Introduction: Chest pain is one of the most common reasons for contacting the emergency medical services (EMS). It is difficult for EMS personnel to distinguish between patients suffering from a high-risk condition in need of prompt hospital care and patients suitable for non-conveyance. A vast majority of patients with chest pain are therefore transported to the emergency department (ED) for further investigation even if hospital care is not necessary.

Objective: To illustrate the role of dehydrocorydaline (DHC) in chronic constriction injury (CCI)-induced neuropathic pain and the underlying mechanism.
Methods: C57BL/6J mice were randomly divided into 3 groups by using a random number table, including sham group (sham operation), CCI group [intrathecal injection of 10% dimethyl sulfoxide (DMSO)], and CCI+DHC group (intrathecal injection of DHC), 8 mice in each group. A CCI mouse model was conducted to induce neuropathic pain through ligating the right common sciatic nerve.
Introduction: wrist ligament injuries and triangular fibrocartilage complex (TFCC) lesions are common but often underdiagnosed conditions causing chronic wrist pain. The diagnostic challenge necessitates a combination of clinical examination, imaging studies, and arthroscopy, considered the gold standard. Ligament injuries, particularly scapholunate ligament (SL), and TFCC lesions account for significant wrist instability and ulnar-sided wrist pain, respectively.

Objective: Diastolic dysfunction (DD) is defined as impaired left ventricular (LV) relaxation, caused by structural or functional heart diseases. We sought to assess the role of cardiac CT angiography (CCTA) as a tool to evaluate LV DD in patients with normal EF using the diastolic expansion index (DEI), as compared to transthoracic echocardiography (TTE) as the gold standard.
Methods: Patients presenting with atypical chest pain with suspected coronary artery disease (CAD) and having a normal LV ejection fraction on TTE underwent CCTA using a dual source CT scanner.

Background: Pain management is a crucial component of patient care that promotes relaxation, lowers complications, improves quality of life, and shortens hospital stays. Several studies assessed the nurses' pain management practices in Ethiopia. However, the findings of these studies are highly variable and inconsistent.
