Purpose: The purpose of this pilot study was to present basic data on shoulder musculoskeletal pain in junior elite tennis players, with data collected via a survey, physical examinations, and musculoskeletal ultrasound. Methods: The participants were eight healthy junior elite Korean tennis players, registered with the Korea Tennis Association. The participants’ characteristics were surveyed using a questionnaire, musculoskeletal pain was assessed, and physical examination and ultrasound examination of the shoulder were performed. Results: The average age of the participants was 13.1±0.8 years (range, 12–14 years), average duration of tennis experience was 3.5±1.5 years (range, 1–6 years), and average player career was 1.6±0.7 years (range, 1–3 years). Six players (75.0%) complained of shoulder pain during and after games. Tennis experience, career length, and training hours were not related to the during- or post-match musculoskeletal pain in the shoulder. Four players (50.0%) showed a 5° to 10° decrease (average, −7.5°±2.4°) in shoulder internal rotation. Acromioclavicular (AC) joint widening (average, 1.8±0.9 mm) was observed in the dominant shoulder in seven players (87.5%). Conclusion Decreased shoulder internal rotation was observed in half of the participants. Ultrasonographic evaluation confirmed significant AC joint widening in the dominant arm. Further research on AC joint widening in junior tennis players is required.

A 29-year-old woman had 1-month history of back pain radiating into lower extremities, motor weakness, and sensory abnormalities in both lower extremities. Contrast-enhanced spinal magnetic resonance imaging (MRI) revealed a homogeneously enhancing mass at the T12∼L1 and several intradural enhancing nodular lesions at L2∼S1. Tumor resection surgery was performed and following histological examination showed that the tumor satisfied the diagnostic criteria for atypical choroid plexus papilloma (CPP). To find primary tumor sites, contrast-enhanced brain MRI, whole spine MRI, and PET-CT were carried out and additional lesions were detected at the fourth ventricle, right cerebellum, and upper thoracic spinal cord. This is a very rare case of metastatic atypical CPP that involves brain, upper thoracic spinal cord, and cauda equina with initial manifestation of radicular symptoms without clinical signs of primary brain lesion.

Contact dermatitis (CD) is one of the most common skin diseases in industrialized countries. Chinese medicines (CMs) have been investigated worldwide as complementary and alternative medicines for corticosteroids, which are the first choice for treatment of inflflammatory skin diseases owing to their favorable efficacy. This article describes the CMs that have been reported to have anti-dermatitis effects against CD in the last 20 years.
