Although splenomegaly is typically uncommon in myelodysplastic syndromes (MDS), it is associated with reduced engraftment rates and poor survival outcomes. Despite its clinical significance, the incidence and genetic associations of splenomegaly in MDS remain understudied. To address this, we conducted a retrospective study of 27 patients with MDS at the Veterans Health Service Medical Center in South Korea. Based on computed tomography scan evaluation, splenomegaly was identified in 26% of patients with MDS, and significant associations with variants in ASXL1 (P = 0.0089 for null and missense/inframe variants) and RUNX1 (P = 0.042 for null variants) were observed, suggesting that these variants are linked to an increased risk of splenomegaly. Notably, one patient with ASXL1 and TET2 variants developed severe splenomegaly (spleen size, 29 cm) following granulocyte colony-stimulating factor (G-CSF) treatment, requiring splenectomy. This case suggests a potential interaction between specific genetic variants and G-CSF sensitivity, potentially exacerbating splenomegaly. Our findings suggest that the incidence of splenomegaly in patients with MDS, including mild cases, is likely underestimated and that ASXL1 and RUNX1 variants increase the risk of splenomegaly. Furthermore, careful monitoring for the development of severe splenomegaly during G-CSF treatment may be warranted in genetically susceptible individuals with MDS.

This review examines the challenges associated with occupational disease surveillance in Korea, particularly emphasizing the limitations of current data sources such as the Industrial Accident Compensation Insurance (IACI) statistics and special health examinations. The IACI system undercounts cases due to its emphasis on severe diseases and restrictions on approvals. Special health examinations, although they cover a broad workforce, are constrained by their annual scheduling, which leads to missed acute illnesses and subclinical conditions. The paper also explores the history of occupational disease surveillance in Korea, highlighting the fragmented and disease-specific approach of earlier systems. The authors introduce the newly established Korea Occupational Disease Surveillance Center (KODSC), a comprehensive nationwide system designed to gather, analyze, and interpret data on occupational diseases through a network of regional centers. By incorporating hospital-based surveillance and focusing on acute poisonings and other sentinel events, the KODSC aims to overcome the limitations of previous systems and promote collaboration with various agencies. Although it is still in the early stages of implementation, the KODSC demonstrates potential for improving data accuracy and contributing valuable insights for public health policy.

Purpose: Papillary thyroid cancer (PTC), a common malignancy among women of reproductive age, is increasingly common during pregnancy because of routine prenatal imaging. However, the optimal timing for surgical treatment remains controversial. This study aimed to assess the safety and practicality of performing thyroid surgery during pregnancy through a comparative analysis of perioperative and pathological outcomes between pregnant and nonpregnant women. Methods: We conducted a retrospective case-control study of 100 female patients aged 20–39 years who underwent thyroid surgery for PTC between January 2019 and December 2024. Patients were grouped into pregnant (n = 14) and nonpregnant (n = 86) cohorts. Clinical, surgical, and pathological data were compared. Results: Most pregnant patients underwent surgery during the second trimester. The operative duration was significantly shorter in the pregnant group than in the nonpregnant group (71.4 ± 26.35 minutes vs. 87.2 ± 5.17 minutes, P = 0.025), and there was a trend towards a lower drain volume on postoperative day 1 (25.2 ± 15.23 mL vs. 32.7 ± 0.18 mL, P = 0.077).No significant differences were observed in terms of complication rates. Despite a higher frequency of extrathyroidal extension (P = 0.003) and advanced T stage (P = 0.038) in the pregnant group, the surgical outcomes were favorable. One neonate experienced mild intraventricular hemorrhage that resolved without sequelae. Conclusion Thyroid surgery during pregnancy, particularly in the second trimester, appears feasible in selected patients.Given the small sample and retrospective nature of this study, larger prospective studies are needed to validate these findings.

Purpose: Although Korea’s medical care uses advanced technology, there are not enough doctors working in rural areas, and fewer doctors are working in challenging fields such as surgery. Medical care in Türkiye is very cost-effective for patients, but doctors have too many patients and too much work. This study compared the healthcare systems of the 2 countries and the gaps felt by surgeons. Methods: A comparative analysis was conducted using a comprehensive literature review and a questionnaire involving medical professionals from various working positions in both countries. Results: Doctors in both countries felt that there was a large medical gap between regions and reported that the number of doctors was small. Turkish doctors experience excessive patient overload, contributing to high stress and feelings of overwork. They also showed lower job satisfaction than in Korea. The common reasons for the low preference for general surgery residencies include intense training, excessive workload, and high risk in both countries. Conclusion This study identified the key challenges in medical and surgical training in Korea and Türkiye. In Korea, shortages can be addressed by reforms in general surgery residency, the development of a balanced residency selection system, and the provision of work opportunities for non-Korean professionals. In Türkiye, improving remuneration and alleviating unsafe work environments is urgent. Both countries should incentivize rural services to ensure balanced doctor distribution. Collaborative initiatives informed by these findings can enhance medical education and healthcare delivery in both countries.

Ovarian fibromatosis is a rare non-neoplastic condition that causes ovarian enlargement in women, typically around the age of 25. This enlargement is due to the proliferation of the collagen-producing ovarian stroma. On T2-weighted MRI, a key diagnostic feature of ovarian fibromatosis is the ‘black garland sign,’ characterized by multilobulated very low signal intensity along the ovarian surface. This condition also features the preservation of normal ovarian stroma or follicles internally. We present a case involving a 65-year-old postmenopausal female who was pathologically misdiagnosed with ovarian fibroma. However, the diagnosis was later revised to ovarian fibromatosis based on characteristic MRI findings.The case report discusses the differential diagnosis and pathologic findings associated with ovarian fibromatosis.

Background: Vitiligo, which is characterized by depigmented patches on the skin, poses challenges in achieving lasting repigmentation after treatment. Identifying factors contributing to vitiligo recurrence is vital for effective management; however, there is a significant knowledge gap regarding post-treatment recurrence factors in patients with vitiligo. Objective: We aimed to investigate the factors associated with recurrence in patients with non-segmental vitiligo. Methods: We retrospectively analyzed patient’s medical records from 2000 to 2023, and defined a “cure group” with cosmetically satisfactorily repigmentation maintained for at least 6 months. This group was further divided into recurrence and non-recurrence groups. We analyzed the clinical characteristics and various factors related to treatment. Furthermore, we explored the cure and recurrence rates based on the location of vitiligo, and performed a survival analysis for recurrence with or without maintenance therapy. Results: Of 70 cured patients, 19 relapsed. Maintenance treatment was the most significant factor affecting vitiligo recurrence (p＜0.0001, odds ratio=0.029). There were no statistically significant differences in initial age, sex, disease duration, sites, subtype, treatment duration, treatment modality, and comorbidities. After 100 months, 87.3% of the patients in the maintenance therapy group remained recurrence-free, while only 20% of the non-maintenance therapy group did not experience recurrence. Head and neck lesions had the highest cure rates, whereas lower limb lesions showed higher recurrence rates. Approximately 63.2% of recurrences occurred at the original site, while 31.6% occurred outside the original site. Conclusion The absence of maintenance therapy was the most important factor associated with the recurrence of nonsegmental vitiligo.
