PURPOSE: We aimed to investigate the extent of heterogeneity in medical terminology between South and North Korea by comparing medical terms related to the colorectal system. METHODS: North Korean medical terms were collected from the sections on diseases of the small intestine and colon in a surgery textbook from North Korea, and those terms were compared with their corresponding terms in a South Korean medical terminology textbook. The terms were categorized as either identical, similar, showing disparity, or not used in South Korea. In a subsection analysis, the terms were allocated to pathophysiology, diagnosis, symptoms and examination, drugs, testing, treatment, or others according to the categorization used in the textbook. RESULTS: We found 705 terms in the North Korean textbook, most of which were pathophysiological terms (206, 29.2%), followed by diagnostic terms (165, 23.4%) and symptom and examination terms (122, 17.3%). Treatment-, drug-, and testing-related terms constituted 15.5%, 5.8%, and 4.1% of the 705 terms, respectively. There were 331 identical terms (47.0%) and 146 similar terms (20.7%); 126 terms (17.9%) showed disparity. Another 102 terms (14.5%) were not used in South Korea. The pathophysiological terms were the least heterogeneous, with 61.2% being identical terms used in both countries. However, 26.8% of the terms in the drug category were not used in South Korea. CONCLUSION: The present study showed that less than 50% of the terms for the colorectal system used in South and North Korea were identical. As the division between South and North Korea persists, the heterogeneity of medical terminology is expected to increase.

Leydig cell tumors are the most common non-germ cell tumors of the testis, and they account for 1-3% of all testicular tumors. They most commonly present as a testicular mass and/or with endocrine symptoms. This tumor is characterized by its endocrine manifestations, which are due to the tumor's capacity to secrete hormones. We report here on one case of a patient with Leydig cell tumor; the patient was without symptoms and the tumor was not detected on the physical examination.

PURPOSE: The purpose of this study was to categorize surgery-related medical terminologies used in South and North Korea and to compare and analyze discrepancies observed in the terms. METHODS: This study collected medical terminology used in the North Korean medical book “Surgery” and compared it to medical terminology found in the medical glossary of South Korea. The order of the subtitle was described according to the Instruction to Authors. RESULTS: In total, there were 2,168 individual medical terms, of which only 1,004 words (46.3%) were identical to South Korean medical terms. There were 581 similar terms (26.8%), 265 different terms (12.2%), and 318 terms that are nonexistent in South Korea (14.7%). CONCLUSION: Less than half of the medical terms used in North Korea match those used in South Korea. It is expected that the prolongation of the current division of South and North Korea will only worsen this discrepancy. Further efforts to bridge the gap through academic exchange between South Korea and North Korea are required in preparation for an era of reunification.

PURPOSE: Surgery is the primary curative treatment for colorectal cancer; however, it remains a frightening procedure that can cause stress and pain in affected patients. Therefore, patients typically experience significant anxiety during the preoperative period, which has been associated with poorer outcome after surgery. This study aimed to evaluate the effect of an Internet-based informational video on preoperative anxiety level in patients with colorectal cancer.

Huntington’s disease (HD) is a neurodegenerative disorder characterized by motor, behavioral, and cognitive impairments and significant impacts on patient quality of life. This evidence-based review, conducted by the Korean Huntington Disease Society task force, systematically examines current pharmacological and nonpharmacological interventions for symptomatic management of HD. Following PRISMA guidelines, databases were searched for studies up to August 2022 that focused on 23 symptoms across four domains: motor, neuropsychological, cognition, and others. This review provides a comprehensive and systematic approach to the management of HD, highlighting the need for more high-quality clinical trials to develop robust evidence-based guidelines.

BACKGROUND AND OBJECTIVES: From the view point of the molecular aspects, the fate of long standing pressure and volume overloaded atrium in severe MR has not been evaluated. This study was performed to elucidate whether apoptosis of right atrial myocytes is related to atrial changes. SUBJECTS AND METHODS: The medical records of 16 patients (M: F=8: 8, mean age=52+/-12), with severe MR having undergone valve replacement surgery, were retrospectively reviewed. The subjects were divided into 2 groups according to the duration of their symptoms (group I, symptom duration less than 12 months, n=10 and group II, more than 12 months, n=6). Using the atrial myocardium specimens obtained during surgery, TUNEL assays and immunohistochemical staining were performed for the expressions of Fas, Bax and the Bcl family. RESULTS: Apoptotic indices of TUNEL assay were 31.1+/-12.6 and 4.9+/-4.3% in groups I and II, respectively (p<0.01). The Fas expressions were 42.1+/-14.4 and 27.8+/-10.5% in groups I and II, respectively (p<0.05), but in group I, with atrial fibrillation (AF), was 49.3+/-6.9%, which was higher than the 29.2+/-12.5% in group I without AF and group II (p<0.001). The Bax expression in group I patients with a left atrial size less than 4 cm was 19.2+/-10.7%, which was higher than the 7.2+/-6.2% in group I with a left atrial size more than 4 cm and group II (p<0.05). CONCLUSION: Programmed cell death of the atrial myocardium, in severe MR, might be an early molecular pathological change rather than the late sequelae. The causality between programmed cell death and electrical and structural changes of the atrium should be further investigated.

BACKGROUND: Autophagy is an important adaptive mechanism in normal development and in response to changing environmental stimuli in cancer. Previous papers have reported that different types of cancer underwent autophagy to obtain amino acids as energy source of dying cells in nutrient-deprived conditions. However, whether or not autophagy in the process of lung cancer causes death or survival is controversial. Therefore in this study, we investigated whether nutrient deprivation induces autophagy in human H460 lung cancer cells. METHODS: H460, lung cancer cells were incubated in RPMI 1640 medium, and the starved media, which are BME and RPMI media without serum, including 2-deoxyl-D-glucose according to time dependence. To evaluate the viability and find out the mechanism of cell death under nutrient-deprived conditions, the MTT assay and flow cytometry were done and analyzed the apoptotic and autophagic related proteins. It is also measured the development of acidic vascular organelles by acridine orange. RESULTS: The nutrient-deprived cancer cell is relatively sensitive to cell death rather than normal nutrition. Massive cytoplasmic vacuolization was seen under nutrient-deprived conditions. Autophagic vacuoles were visible at approximately 12 h and as time ran out, vacuoles became larger and denser with the increasing number of vacuoles. In addition, the proportion of acridine orange stain-positive cells increased according to time dependence. Localization of GFP-LC3 in cytoplasm and expression of LC-3II and Beclin 1 were increased according to time dependence on nutrient-deprived cells. CONCLUSION: Nutrient deprivation induces cell death through autophagy in H460 lung cancer cells.
