Colonoscopy is a key procedure for the early detection of colorectal cancer. Despite its importance, the discomfort associated with colonoscopy often requires sedation, and the ideal sedation regimen remains to be determined. In this prospective randomized controlled trial, patients scheduled for colonoscopy were randomly assigned to two different sedation protocols. Group A received a combination of midazolam and propofol, while group B was given midazolam and pethidine. The study analyzed data from 51 patients, with 23 in group A and 28 in group B. The incidence of adverse events was similar across both groups. Additionally, no significant differences were observed in cecal intubation times or total procedure durations. Notably, group A had a lower frequency of required postural changes (1.0±0.7 vs. 1.5±0.7, p=0.02) and a reduced rate of manual compression (52.2% vs. 82.1%, p=0.02). There were no significant differences between the groups regarding subjective pain or overall satisfaction. Both sedation regimens were found to be safe and effective. The midazolam and propofol combination was associated with a smoother procedure, evidenced by fewer postural adjustments and less manual compression needed during colonoscopy.

Objective: It is unknown whether artificial intelligence-based computer-aided detection (AI-CAD) can enhance the accuracy of chest radiograph (CR) interpretation in real-world clinical practice. We aimed to compare the accuracy of CR interpretation assisted by AI-CAD to that of conventional interpretation in patients who presented to the emergency department (ED) with acute respiratory symptoms using a pragmatic randomized controlled trial. Materials and Methods: Patients who underwent CRs for acute respiratory symptoms at the ED of a tertiary referral institution were randomly assigned to intervention group (with assistance from an AI-CAD for CR interpretation) or control group (without AI assistance). Using a commercial AI-CAD system (Lunit INSIGHT CXR, version 2.0.2.0; Lunit Inc.). Other clinical practices were consistent with standard procedures. Sensitivity and false-positive rates of CR interpretation by duty trainee radiologists for identifying acute thoracic diseases were the primary and secondary outcomes, respectively. The reference standards for acute thoracic disease were established based on a review of the patient’s medical record at least 30 days after the ED visit. Results: We randomly assigned 3576 participants to either the intervention group (1761 participants; mean age ± standard deviation, 65 ± 17 years; 978 males; acute thoracic disease in 472 participants) or the control group (1815 participants; 64 ± 17 years; 988 males; acute thoracic disease in 491 participants). The sensitivity (67.2% [317/472] in the intervention group vs. 66.0% [324/491] in the control group; odds ratio, 1.02 [95% confidence interval, 0.70–1.49]; P = 0.917) and false-positive rate (19.3% [249/1289] vs. 18.5% [245/1324]; odds ratio, 1.00 [95% confidence interval, 0.79–1.26]; P = 0.985) of CR interpretation by duty radiologists were not associated with the use of AI-CAD. Conclusion AI-CAD did not improve the sensitivity and false-positive rate of CR interpretation for diagnosing acute thoracic disease in patients with acute respiratory symptoms who presented to the ED.

Background: Hormone replacement therapy (HRT) is used to relieve menopause symptoms, but has been reported to be associated with coronary heart disease and cancers in women.However, a link between HRT and psoriasis has yet to be established. The aim of this study was to determine the association between HRT and the risk of psoriasis. Methods: We executed a nationwide population-based study. A total of 1,130,741 postmenopause women were enrolled in the national health care insurance database based on the enrollment criteria. The study population was classified into four groups based on the duration of the HRT, and the risk of psoriasis was analyzed. Results: The incidence rates of psoriasis per 1,000 person-years were 3.36 and 4.09 in the no history of HRT and ≥ 5 years of HRT, respectively. After adjustment for age, smoking, alcohol intake, regular exercise, body mass index, diabetes mellitus, hypertension, and dyslipidemia, the most prolonged duration of the HRT group (≥ 5 years) exhibited significantly increased risk of developing psoriasis (hazard ratio, 1.22; 95% confidence interval, 1.16–1.29). Conclusion We propose that HRT in post-menopausal women is associated with an increased likelihood of psoriasis development.

Diagnostic techniques for spinal pathologies have been developed in accordance with advances in technology. Accurate diagnosis of spinal pathology is essential for appropriate management of spinal diseases. Since the development of X-rays in 1895 and computed tomography (CT) in 1967, several diagnostic imaging modalities have been utilized for detecting spinal pathologies, including radiography, CT, magnetic resonance imaging, and radionuclide imaging. In addition to diagnostic imaging technologies, electrodiagnostic tests, including electromyography and nerve conduction studies, play a significant role as diagnostic tools, as spinal diseases are mostly profoundly associated with pathologies of the neural structures, such as the spinal cord and nerve root, and extent of injury at the structure cannot be adequately detected by conventional imaging techniques. In patient-specific treatment strategies, usage of diagnostic modalities is of great importance; thus, we should be aware of the basic details and approaches of the different diagnostic modalities. In this review, the authors discuss the details of the technologies that aid in the diagnosis of spinal pathologies.

Background: Psoriasis is a relapsing inflammatory skin disorder that can affect the nails and joints. Psoriatic arthritis (PsA) occurs in up to 30% of patients with psoriasis, leading to chronic articular pain, and impairing quality of life. Secukinumab is a human monoclonal antibody targeting interleukin-17A that has been shown to effectively improve the clinical signs and symptoms of PsA. Objective: To evaluate the effect of secukinumab on health-related quality of life (HRQOL) in Korean PsA patients. Methods: We retrospectively investigated the medical records and psoriasis area and severity index (PASI) scores of 13 patients with PsA who completed the psoriatic arthritis impact of disease 12-item questionnaire (PsAID-12) before and 3 months after receiving secukinumab treatment between October 2019 and August 2021 in Yeouido St.Mary’s Hospital. Results: At week 12, significant reductions in the total and each item PsAID-12 and mean PASI score were observed (p＜0.01). The mean decrease of total PsAID-12 score was 4.8 (95% confidence interval [CI], 3.74∼5.86), with the greatest improvement observed in the item of ‘embarrassment’ (7.15; 95% CI, 5.59∼8.72). Of the 13 patients, 11 (84.6%) and 5 (38.5%) achieved PASI75 and PASI90 response, respectively. Conclusion This study showed that secukinumab improves the HRQOL of patients with PsA, implying a positive influence of secukinumab on patients’ physical and mental status in a real-world clinical setting.

Background and Objectives: Although several studies have compared the characteristics of Ramsay Hunt syndrome (RHS) with Bell’s palsy (BP), the differences in comorbid symptoms and prognosis according to symptoms have not been determined. This study therefore evaluated the differences in otologic symptoms and prognosis between patients with these two conditions.Subjects and Method The medical records of 118 patients with RHS and 215 patients with BP were retrospectively reviewed. Factors compared in these two groups included otologic symptoms, general health condition, electroneurography (ENoG) and House-Brackmann grades. Results: Age, sex, body mass index, lipid profiles, ENoG, rate of diabetes, and side of palsy did not differ significantly between patients with RHS and BP (p>0.05). The rates of hearing disturbance, tinnitus, vertigo, and postauricular pain were significantly higher in RHS (p<0.05 each). Hearing disturbance was more frequent in patients with severe Bell’s facial palsy than with moderate Bell’s facial palsy (p<0.05). The prognosis of patients with BP and RHS who had otologic symptoms did not differ from those who had not (p>0.05). Additionally, in patients with facial paralysis, diabetes was associated with hearing disturbance and vertigo symptoms and dyslipidemia was associated with postauricular pain (p<0.05 each). Conclusion Otologic symptoms were more common in RHS than in BP. However, the prognosis of RHS and BP were not related to otologic symptoms. In patients with facial palsy hearing disturbance and vertigo were associated with diabetes and hypertension. Also, dyslipidemia was associated with post auricular pain.

Evidence of the ethical appropriateness and clinical benefits of shared decision-making (SDM) are accumulating. This study aimed to not only identify physicians’ perspectives on SDM, and practices related to end-of-life care in particular, but also to gauge the effect of SDM education on physicians in Korea. Methods: A 14-item questionnaire survey using a modified Delphi process was delivered to nephrologists and internal medicine trainees at 17 university hospitals. Results: A total of 309 physicians completed the survey. Although respondents reported that 69.9% of their practical decisions were made using SDM, 59.9% reported that it is not being applied appropriately. Only 12.3% of respondents had received education on SDM as part of their training. The main obstacles to appropriate SDM were identified as lack of time (46.0%), educational materials and tools (29.4%), and education on SDM (24.3%). Although only a few respondents had received training on SDM, the proportion of those who thought they were using SDM appropriately in actual practice was high; the proportion of those who chose lack of time and education as factors that hindered the proper application of SDM was low. Conclusion: The majority of respondents believed that SDM was not being implemented properly in Korea, despite its use in actual practice. To improve the effectiveness of SDM in the Korean medical system, appropriate training programs and supplemental policies that guarantee sufficient application time are required.

We performed a point seroprevalence survey of measles among healthcare workers (HCWs) at two Korean teaching hospitals in 2019. A total of 2,830 HCWs underwent an antibody test.The overall seropositivity of measles was 93.1%. The seroprevalence of measles was lowest in HCWs aged 20 - 24 years (81.2%), followed by those aged 25 - 29 years (90.1%). The rates of anti-measles IgG positivity were significantly different between the two hospitals (97.0% vs.89.4%, P <0.001). These results suggest that the seropositivity of measles in HCWs may differ depending on the hospital's vaccination policy.

A 64-year-old man was treated with sunitinib as a first-line therapy for metastatic renal cell carcinoma. He was given oral sunitinib in cycles of 50 mg once daily for 2 weeks followed by a week off. During the 5th week of treatment right upper quadrant pain developed, but this resolved spontaneously during the 6th week (off treatment). However, on the 8th week of treatment, he was admitted to hospital because the acute right upper quadrant pain recurred with nausea, vomiting, and fever. Acute acalculous cholecystitis was then diagnosed by ultrasonography and CT. In addition, his laboratory findings indicated disseminated intravascular coagulation. Accordingly, sunitinib therapy was discontinued and broad-spectrum antibiotics initiated. He subsequently recovered after emergent percutaneous cholecystostomy. His Naranjo Adverse Drug Reaction Probability Scale score was 7, indicaing a probable association of the event with sunitinib. Suspicion of sunitinib-related acute cholecystitis is required, because, although uncommon, it can be life-threatening.
