[Purpose]We report a case concerning 5 months of left elbow and knee joint pain thought to be caused by repetitive use at work. Symptoms were improved successfully (checked by M-test) by a single acupuncture treatment.
[Case]We used acupuncture to treat a 50-year-old woman who visited our Acupuncture and Moxibustion Centerwith complaints of increasing elbow and knee joint pain in the left side. Since 4 months ago, her job involved frequent stair-climbing while carrying an 18-liter can of cooking oil. The soft tissues seemed to be damaged and caused pain due to the repeated lifting of heavy cans at work. Acu-points were decided by M-Test to check limitations of movement, which identified damaged regions and provided feedback for optimal treatment. According to the specific operations of the patient's work, we identified limited movements of left-elbow joint flexion-extension, left-shoulder joint extension, and left hip joint inner rotation and external gyration. These were regarded as target motions for the treatment. Her Visual Analog Scale (VAS) scores before treatment were 90 mm in the left elbow and 80 mm in the left knee. Despite only a single round of acupuncture treatment, the respective values dropped to 18 mm and 15 mm.
[Consideration and Conclusion]The limited movement identified by M-Test could expose the affected areas and help in treating the appropriate acu-points. Therefore, acupuncture using M-Test might improve painful motions of the body.

In mass casualty incidents, effective triage, treatment, and transport are critical for efficient management but often deviate from practices and ethical standards. In terms of resource allocation, decentralized transport is the predominant transport method; however, it is not standardized. This report retrospectively analyzed the response to a mass casualty incident at a university emergency center. By centralizing patient transport from the scene, the time to patient transport could be shortened, the burden on the scene related to transport could be reduced, and undertriage at the scene could be avoided. No trauma-related deaths occurred. This case provides a valuable contribution to the understanding of situations in which critical patients may concentrate in emergency centers during future mass-casualty incidents.

Objective: This study aimed to identify prognostic factors for hypothermia, including hormone levels.Materials and Methods: This retrospective analysis used data from our department’s database from November 2018 to December 2023. Inclusion criteria comprised cases with a prehospital diagnosis of hypothermia (body temperature <35°C) established by emergency medical technicians. Patients in cardiac arrest upon arrival were excluded from the study. This study investigated various parameters, including age, sex, body temperature, systolic blood pressure, heart rate, Glasgow Coma Scale (GCS) score, and adrenocorticotropic hormone (ACTH), cortisol, thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), C-reactive protein, total protein, albumin levels, and outcomes. Patients were categorized into two groups based on the discharge outcome: fatal and survival groups. This study compared the variables between the two groups.Results: There were 28 and 53 patients in the fatal and survival groups, respectively. The average heart rate and FT3 levels in the fatal group were significantly lower than those in the survival group. The average cortisol and CRP levels in the fatal group were significantly higher than those in the survival group.Conclusion: This is the first report to demonstrate that hypothermic patients with a fatal outcome tend to have low heart rate, low FT3 levels, high cortisol levels, and inflammation upon arrival at the hospital. Further studies with larger sample sizes are needed to confirm the clinical significance of our findings.
