By comparing lesions rich in MCs with those having fewer MCs, we sought to elucidate the role of MCs in the inflammatory mechanisms underlying rosacea pathogenesis. <b>Methods:</b> Specimens were collected from 20 patients diagnosed with rosacea who attended the outpatient clinic between 2008 and 2013. Each specimen underwent staining using hematoxylin/eosin, Giemsa, IL-6, LL-37, and TNF-α for both histopathological and immunohistochemical analyses. The number of stained cells was counted across 10 randomly selected dermal layers at a magnification of ×400 using light microscopy. The results were categorized based on the number of MCs counted: more than 10 MCs were classified as MC-rich, and 10 or fewer MCs as MC-poor. <b>Results:</b> Among the 20 patients (10 MC-rich and 10 MC-poor), the MC-rich group demonstrated significantly higher MC counts than the MC-poor group (P<0.001). However, there were no significant differences in the expression levels of IL-6, LL-37, or TNF-α between the two groups. Additionally, MC density did not show any significant associations with patient demographics, clinical characteristics, or systemic comorbidities. <b>Conclusion:</b> Increased MC density was not associated with differences in IL-6, TNF-α, or LL-37 expression in rosacea lesions. These findings suggest that MC infiltration may not directly influence the inflammatory mediator profile in rosacea.

The prevalence of shoulder pain is on the rise, especially in societies with aging populations. Like other joint-related conditions, shoulder pain is predominantly caused by degenerative diseases. These degenerative changes typically affect bones, tendons, and cartilage, with common conditions including degenerative rotator cuff tears, impingement syndrome, and osteoarthritis. Diagnosing these degenerative diseases in older adults requires a thorough understanding of basic anatomy, general physical examination techniques, and specific diagnostic tests. This review aims to outline the fundamental physical examination methods for diagnosing shoulder pain in older adult patients in primary care. The shoulder's complex anatomy and its broad range of motion underscore the need for a systematic approach to evaluation. Routine inspection and palpation can identify signs such as muscle atrophy, bony protrusions, or indications of degenerative changes. Assessing range of motion, and distinguishing between active and passive deficits, is crucial for differentiating conditions like frozen shoulder from rotator cuff tears. Targeted strength tests, such as the empty can, external rotation lag, liftoff, and belly press tests, are instrumental in isolating specific rotator cuff muscles. Additionally, impingement tests, including Neer's and Hawkins' signs, are useful for detecting subacromial impingement. A comprehensive understanding of shoulder anatomy and a systematic physical examination are vital for accurately diagnosing shoulder pain in older adults. When properly executed and interpreted in the clinical context, these maneuvers help differentiate between various conditions, ranging from degenerative changes to rotator cuff pathology.</p>","PeriodicalId":41392,"journal":{"name":"Ewha Medical Journal","volume":"48 1","pages":"e8"},"PeriodicalIF":0.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12277894/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144699910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The focus on cultivating young teachers is increasingly geared towards personalization and diversification, which are essential for advancing education in pathophysiology. High-quality young teachers are pivotal in raising teaching standards, fostering research innovation, and facilitating interdisciplinary exchanges. Based on these insights, we recommend several practical measures to enhance the quality of pathophysiology education in China. These include establishing comprehensive training programs that integrate teaching innovation and research skills; developing structured mentorship systems with clear pathways for career advancement; creating platforms that support technology-enhanced teaching and international collaboration; and implementing systematic evaluation mechanisms to assess teaching effectiveness.

This review aims to examine the radiologic findings associated with these shoulder conditions in older patients, providing insights for accurate diagnosis and effective treatment. Adhesive capsulitis, commonly known as frozen shoulder, leads to pain and restricted movement, thereby causing shoulder dysfunction. Recent advances in diagnostic technology have greatly enhanced the sensitivity and accuracy of diagnosing this condition through radiologic evaluations, including MRI, magnetic resonance arthrography (MRA), and high-resolution ultrasound. Rotator cuff disease is another frequent issue in older adults, with full-thickness tears occurring in 50%-80% of cases. Both MRI and MRA are highly sensitive and specific in identifying rotator cuff tears. Additionally, ultrasonography is recognized for its high sensitivity and specificity in detecting tears of the supraspinatus tendon. Although osteoarthritis of the glenohumeral joint is less commonly prevalent, its advanced stages can severely affect the function of the upper extremity. Plain radiography is typically the first imaging technique used to assess this type of osteoarthritis. As the condition worsens, CT is utilized to measure glenoid bone loss, glenoid version, and inclination, which are crucial for accurate surgical planning. Each imaging modality provides distinct benefits: plain radiographs for initial structural assessment, ultrasonography for real-time evaluation of soft tissues, MRI/MRA for detailed visualization of capsular and tendinous lesions, and CT for precise bony analysis.</p>","PeriodicalId":41392,"journal":{"name":"Ewha Medical Journal","volume":"48 1","pages":"e10"},"PeriodicalIF":0.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12277897/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144699912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prevalence of PPD ranged from 5.1% to 78.7%. Key associated factors for PPD included cultural factors such as relationships with in-laws and preferences for the newborn's sex.
