Objective: Pathological features indicating metastatic mucinous carcinoma to the ovary (MMCO) have been rarely reported in primary mucinous ovarian carcinoma (PMOC). However, little is known about how often they are observed in PMOC and how they relate to patient prognosis. In this study, we investigated the pathological features indicating MMCO in a large cohort of PMOCs and analyzed their association with patient prognosis. Methods: We reviewed surgically treated PMOC patients diagnosed at the Seoul National University Hospital from 1995 to 2019, according to the updated WHO classification, and investigated the presence of pathological features indicating MMCO. Results: A total of 144 patients with PMOCs were included. The 5 pathological findings indicating MMCO, including an infiltrative invasive pattern, the absence of benign or borderline components, a smaller tumor size, the presence of signet ring cells and the presence of extracellular mucin were observed in PMOC (21.6%, 43.1%, 20.8%, 4.3% and 12.9%, respectively), and were significantly correlated with poor overall and progression-free survival rates in PMOC. The patient’s prognosis worsened as the extent of the infiltrative invasive pattern increased (p<0.001). In addition, the prognostic power was stronger when the 5 pathological factors were analyzed together (new grouping system) than when analyzed individually (p<0.001) and the new grouping system was identified as an independent prognostic factor regardless of FIGO stage. Conclusion Five pathological findings indicating MMCO in PMOC were significantly associated with poor prognosis in PMOC patients. Also, the new grouping system combining these findings was identified as an independent prognostic factor.

Therapeutic management of brain tumors is based on accurate knowledge of their size, location and histologic type. Stereotaxic cytology under CT guidance has been applied to the investigation of brain tumors, especially in the sellar turcica, third ventricle, and pineal regions. In the present case, the tumor protruded into the nasal cavity, so we were able to get cytologic material via fine needle aspiration.

PURPOSE: The Mongolian National University of Medical Sciences is the only national university in Mongolia and has produced more than 90% of health professionals in the country. Experts from Mongolia and Korea embarked on a collaborative effort to develop educational programs for faculty development based on the personal and professional needs of faculty members. This study aimed to evaluate the outcomes of those educational programs to determine whether this transnational collaboration was successful. METHODS: A needs assessment survey was conducted among 325 faculty members. Based on the results of this survey, the joint expert team developed educational programs on seven core topics: clinical teaching, curriculum development, e-learning, item writing, medical research, organizational culture, and resident selection. Surveys evaluating the satisfaction and the attitudes of the participants were conducted for each program. RESULTS: Throughout the 17-day program, 16 experts from Korea and 14 faculty members from Mongolia participated as instructors, and a total of 309 participants attended the program. The average satisfaction score was 7.15 out of 8.0, and the attitudes of the participants towards relevant competencies significantly improved after each educational program. CONCLUSION: The faculty development programs that were developed and implemented as part of this transnational collaboration between Mongolia and Korea are expected to contribute to the further improvement of health professions education in Mongolia. Future studies are needed to evaluate the long-term outcomes of these educational programs.

Subacute sclerosing panencephalitis (SSPE) is a rare, progressive, and fatal central nervous system disorder resulting from persistent measles virus infection. Long-term data are scarce, with a maximum follow-up period of 10 years. Interferon-alpha (IFN-α) is a protein that exerts its antiviral activity via enhancement of cellular immune response and is reported to be an effective drug for the treatment of SSPE. However, there is currently no consensus regarding the optimal duration of IFN-α therapy. Here, we present a case report of a patient with SSPE treated with long-term intraventricular IFN-α therapy, which facilitated clinical improvement and neurological stabilization without causing serious adverse effects. To the best of our knowledge, this is one of the longest follow-up studies investigating a patient with SSPE receiving intraventricular INF-α treatment. Further studies are necessary to validate the benefits and safety of long-term intraventricular IFN-α treatment in patients with SSPE.

Abnormal aggregation of α-synuclein is a key element in the pathogenesis of several neurodegenerative diseases, including Parkinson’s disease (PD), dementia with Lewy bodies, and multiple system atrophy. α-synuclein aggregation spreads through various brain regions during the course of disease progression, a propagation that is thought to be mediated by the secretion and subsequent uptake of extracellular α-synuclein aggregates between neuronal cells. Thus, aggregated forms of this protein have emerged as promising targets for disease-modifying therapy for PD and related diseases. Here, we generated and characterized conformation-specific antibodies that preferentially recognize aggregated forms of α-synuclein. These antibodies promoted phagocytosis of extracellular α-synuclein aggregates by microglial cells and interfered with cell-to-cell propagation of α-synuclein. In an α-synuclein transgenic model, passive immunization with aggregate-specific antibodies significantly ameliorated pathological phenotypes, reducing α-synuclein aggregation, gliosis, inflammation, and neuronal loss. These results suggest that conformation-specific antibodies targeting α-synuclein aggregates are promising therapeutic agents for PD and related synucleinopathies.
