This study examines the legality and appropriateness of keeping the multiple-choice question items of the Korean Medical Licensing Examination (KMLE) confidential. Through an analysis of cases from the United States, Canada, and Australia, where medical licensing exams are conducted using item banks and computer-based testing, we found that exam items are kept confidential to ensure fairness and prevent cheating. In Korea, the Korea Health Personnel Licensing Examination Institute (KHPLEI) has been disclosing KMLE questions despite concerns over exam integrity. Korean courts have consistently ruled that multiple-choice question items prepared by public institutions are non-public information under Article 9(1)(v) of the Korea Official Information Disclosure Act (KOIDA), which exempts disclosure if it significantly hinders the fairness of exams or research and development. The Constitutional Court of Korea has upheld this provision. Given the time and cost involved in developing high-quality items and the need to accurately assess examinees’ abilities, there are compelling reasons to keep KMLE items confidential. As a public institution responsible for selecting qualified medical practitioners, KHPLEI should establish its disclosure policy based on a balanced assessment of public interest, without influence from specific groups. We conclude that KMLE questions qualify as non-public information under KOIDA, and KHPLEI may choose to maintain their confidentiality to ensure exam fairness and efficiency.

Background: The rapid economic development of South Korea provides a unique model to study changes in the clinical characteristics, treatment approaches, and clinical outcomes of patients with rheumatic mitral stenosis (MS) relative to socioeconomic growth. Methods: From the Multicenter mitrAl STEnosis with Rheumatic etiology (MASTER) registry, 2,337 patients diagnosed with moderate or severe rheumatic MS between January 2001 and December 2020 were analyzed. Patients were grouped into consecutive 5-year intervals based on their year of diagnosis. Clinical characteristics, echocardiographic data, and clinical outcomes were assessed. Results: Over 20 years, the severity of mitral stenosis increased from 79.1% to 90.2%; similarly, the average age at diagnosis increased from 54.3 to 63.0 years (all P < 0.001). Comorbidities such as hypertension and atrial fibrillation increased (6.3% to 29.5% and 41.4% to 46.9%, respectively; all P for trend < 0.05). The rate of mitral intervention within five years after diagnosis increased from 31.2% to 47.4% (P for trend < 0.001). However, clinical outcomes of rheumatic mitral stenosis deteriorated over time in the composite outcomes (log-rank test, P < 0.001). Conversely, the incidence of stroke remained stable (60.6–73.7%; P < 0.001), which might be attributed to the increased use of anticoagulation therapy. Conclusion This study observed an increase in patient age, comorbidities, and valve disease severity as the country transitioned from a developing to developed status. Despite a rise in mitral valve interventions, clinical outcomes deteriorated over 20 years, highlighting the need for modified treatment approaches to improve patient outcomes.

Background/Aims: The worldwide coronavirus disease 2019 pandemic has led endoscopists to use personal protective equipment (PPE) for infection prevention. This study aimed to investigate whether wearing a face shield as PPE affects the quality of colonoscopy. Methods: We reviewed the medical records and colonoscopy findings of patients who underwent colonoscopies at Asan Medical Center, Korea from March 10 to May 31, 2020. The colonoscopies in this study were performed by five gastroenterology fellows and four expert endoscopists. We compared colonoscopy quality indicators, such as withdrawal time, adenoma detection rate (ADR), mean number of adenomas per colonoscopy (APC), polypectomy time, and polypectomy adverse events, both before and after face shields were added as PPE on April 13, 2020. Results: Of the 1,344 colonoscopies analyzed, 715 and 629 were performed before and after the introduction of face shields, respectively. The median withdrawal time was similar between the face shield and no-face shield groups (8.72 minutes vs 8.68 minutes, p=0.816), as was the ADR (41.5% vs 39.8%, p=0.605) and APC (0.72 vs 0.77, p=0.510). Polypectomy-associated quality indicators, such as polypectomy time and polypectomy adverse events were also not different between the groups. Quality indicators were not different between the face shield and no-face shield groups of gastroenterology fellows, or of expert endoscopists. Conclusions Colonoscopy performance was not unfavorably affected by the use of a face shield. PPE, including face shields, can be recommended without a concern about colonoscopy quality deterioration.

Purpose: Internal hernia after gastrectomy is a rare but potentially life-threatening condition without surgical intervention. Clinical risk factors of internal hernia should, hence, be reviewed after gastrectomy.From 2008 to 2018, patients who underwent gastrectomy for gastric cancer were investigated. Methods: Abdominal computed tomography (CT) was used to screen for internal hernia, and surgical exploration was performed to confirm the diagnosis. Using retrospective statistical analysis, the incidence, characteristics, and risk factors were identified, and the characteristics of the internal hernia group were reviewed. Results: The overall incidence of internal hernia was 0.9%. From statistical analysis, it was found that laparoscopic surgery was almost five times riskier than open gastrectomy (odds ratio [OR], 4.947; 95% confidence interval [CI], 1.308–18.710; p = 0.019). Body mass index < 25 kg/m2 (OR, 4.596; 95% CI, 1.056– 20.004; p = 0.042) and proximal gastrectomy (OR, 4.238; 95% CI, 1.072–16.751; p = 0.039) were also associated with internal hernia. Among 20 patients with internal hernia, 12 underwent laparotomy, and five had their bowels removed due to ischemia. All patients with bowel resected had suffered from short bowel syndrome. Conclusion Suspecting an internal hernia should be an important step when a patient with a history of laparoscopic gastrectomy visits for medical care. When suspected, emergent screening through CT scan and surgical intervention should be considered as soon as possible to prevent lifetime complications accordingly.

Purpose: To compare early changes in the macular retinal nerve fiber layer (mRNFL) and ganglion cell-inner plexiform layer (mGCIPL) thicknesses according to the severity of initial optic disc edema in optic neuritis patients using swept-source optical coherence tomography (SS-OCT). Methods: We retrospectively reviewed 18 eyes of patients diagnosed with naïve optic neuritis along with optic disc edema who underwent SS-OCT. The central thickness of the optic nerve head and the peripapillary retinal thickness were measured at the initial visit. To quantitate the degree of initial optic disc edema, we calculated the difference of each measurement between the affected eye and the normal fellow eye. The mRNFL and mGCIPL thicknesses were measured at the initial visit and at the 1 month follow-up. The association between changes in mRNFL and mGCIPL thicknesses at the 1 month follow-up and the severity of initial optic disc edema were evaluated. Results: In the affected eye, the mGCIPL thickness was reduced at 1 month. The central thickness of the optic nerve head at the initial visit correlated with the reduction in the temporal mGCIPL at 1 month (R = 0.648, p = 0.045). Furthermore, thicker nasal peripapillary retinal thickness at the initial visit correlated with a reduction in nasal (R = 0.659, p = 0.038) and temporal (R = 0.774, p = 0.009) mGCIPL at 1 month. Thicker temporal peripapillary retinal thickness at the initial visit correlated with reduction in the nasal (R = 0.646, p = 0.044) and temporal (R = 0.760, p = 0.011) mGCIPL at 1 month. Conclusions In optic neuritis patients with optic disc edema, severe optic disc edema, evaluated by peripapillary retinal thickness and central thickness of the optic nerve at the initial visit was associated with a reduced temporal mGCIPL thickness at 1 month. This study suggested that initially severe optic disc edema in optic neuritis patients can predict a rapid decline in the mGCIPL.

Objective: : The method of approach during transforaminal endoscopic lumbar discectomy (TELD) has been the subject of repeated study. However, the ideal entry point during TELD has not been studied in detail. Therefore, this study investigated the ideal entry point for avoiding complications using computed tomography (CT) scans obtained from patients in the prone position. Methods: : Using CT scans obtained from patients in the prone position, we checked for retroperitoneal or visceral violations and measured the angles of approach with five conventional approach lines drawn on axial CT scans at each disc space level (L2–3, L3–4, and L4–5). We also determined the ideal entry point distance and approach angles for avoiding retroperitoneal or visceral violations.Correlation analysis was performed to identify the patient characteristics related to the ideal entry point properties. Results: : We found that the far lateral approach at the L2–3 level resulted in high rates of visceral violation. However, rates of visceral violation at the L3–4 and L4–5 levels were remarkably low or absent. The ideal angles of approach decreased moving caudally along the spine, and the ideal entry point distances increased moving caudally along the spine. Weight, body mass index (BMI), and the depth of the posterior vertebral line from the skin were positively associated with the distance of the ideal entry point from the midline. Conclusion : We reviewed the risk of the extreme lateral approach by analyzing rates of retroperitoneal and visceral violations during well-known methods of approach. We suggested an ideal entry point at each level of the lumbar spine and found a positive correlation between the distance of the entry point to the midline and patient characteristics such as BMI, weight, and the depth of the posterior vertebral line from the skin.

BACKGROUND: Phlebotomy performed for laboratory testing has the potential to cause anemia in newborns and infants. This study investigated the minimum specimen volume required for an automated immunohematology analyzer DAYmate S. METHODS: Three combinations of tubes were evaluated: I. 6 mL EDTA tube, II. 0.5 mL microtainer (on top of 3 mL EDTA tube), and III. 1 mL sample cup (on top of 6 mL EDTA tube). ABO/RhD cell typing was done using centrifuged red cells; unexpected antibody screening was carried out using plasma, and Type & Screening was conducted using whole blood samples. The lowest specimen volume capable of performing 10 repetitive tests without errors was investigated. RESULTS: ABO/RhD cell typing could be performed from I. 30 μL, II. 25 μL, and III. 25 μL. Unexpected antibody screening could be performed from I. 170 μL, II. 150 μL, and III. 140 μL. According to the hematocrit levels, Type & Screening could be performed from 30%, I&III 650 μL, II. 800 μL; 40%, I&III 650 μL, II. 900 μL; and 50%, I&III 1,000 μL, II. Testing using specimen volumes below 1,000 μL was difficult. CONCLUSION: By separating red cells and plasma, pre-transfusion testing of ABO/RhD cell typing and unexpected antibody screening could be conducted with very small specimen volumes using DAYmate S compared to Type & Screening using whole blood. The application of small-sized sample tubes was more competitive and this is expected to be very useful for preventing iatrogenic anemia in neonates and infants less than 4 months old.

Approximately 15% of patients with frontotemporal dementia (FTD) have co-occurring motor neuron disease (MND). FTD-MND cases have frontotemporal lobar degeneration (FTLD)-transactive response DNA-binding protein (TDP) pathology, which is divided into four subtypes (types A, B, C, and D) based on the morphological appearance, cellular location, and distribution of the abnormal TDP inclusions and dystrophic neurites. We report a patient with FTD-MND whose pathological diagnosis was FTLD-TDP type B. This is the first documented autopsy-confirmed case of FTD-MND in Korea.
