Objective: In this study, we investigate the effect of depressive symptoms in elderly on general and cancer health screening participation using the large epidemiological study data in South Korea. Methods: This study was conducted on 1,977 people who responded to a health examination questionnaire among 2,360 adults aged 60 or older who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) in 2020.Depressive symptoms were measured by the Patient Health Questionnaire-9 and classified as minimal (0-4), mild (5-9), and moderate and severe (10-27). To investigate the relationship between depressive symptoms and health screening participation, a multiple logistic regression model controlling covariates was used. Results: Compared to the group with minimal depressive symptoms, the mild group did not show a significant difference (odd ratio [OR]=0.71, 95% confidence interval [95% CI]=0.45-1.13), but the moderate to severe group showed a significant negative relationship with general health screening participation (OR=0.59, 95% CI=0.35-0.99). There was a significant negative relation-ship between depressive symptoms and cancer health screening participation (mild group OR=0.77, 95% CI=0.48-1.23; moderate to severe group OR=0.50, 95% CI=0.28-0.87). Conclusion This study showed that people with depressive symptoms are less likely to get a general and cancer health screening. In order to promote health screening participation, policies that consider health behavior promotion programs and psychiatric interventions targeting moderate to severe depressive symptom groups are necessary.

A 79-year-old man visited neurology clinic due to gait ataxia and vertigo for 10 months. Neurologic examination revealed saccadic pursuit, mild dysmetria, impaired tandem gait, and areflexia that recovers after exercise. The amplitude of compound muscle action potentials recorded on the abductor digiti minimi increased up to 6,639.4% during repetitive nerve stimulation at 50 Hz stimulation. This case demonstrates that clinicians should consider Lambert-Eaton myasthenic syndrome as a differential diagnosis when a patient complains of gait ataxia and vertigo.

Background: The post-traumatic stress disorder (PTSD) Checklist (PCL)-5, originally a 20-item self-questionnaire, has provided abbreviated versions of the checklist. This study aimed to test the diagnostic utility and validity of four brief versions of PCL-5 in a sample of adults seeking treatment at a psychiatric outpatient unit in a South Korean university-affiliated hospital. Methods: The sample comprised 97 adults diagnosed with PTSD and 130 diagnosed with other psychiatric disorders seeking treatment. Each abbreviated scale was examined with the area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and positive predictive power. Additionally, internal consistency, correlation with full scale, convergent validity, and concurrent validity were investigated. Results: All four versions demonstrated excellent discriminative power, with AUC values of >0.9. Suggested cut-off scores were 6, 8, 11, and 16 for the short four-item version (S4), PCL4, PCL6, and PCL8, respectively. Internal consistency was adequate or good except for S4. Additionally, brief scales demonstrated good convergent validity with depression and anxiety scales and excellent concurrent validity with other PTSD scales. Conclusion This study confirms the excellent diagnostic utility and adequate validity of four abbreviated versions of the Korean translation of PCL-5 in the clinical trial.

Background: While individuals exposed to radiation in hospitals are typically registered as radiation workers, with regulated exposure levels, many interns and residents who are not registered as radiation workers are occupationally exposed to radiation. This study aimed to assess the current status and awareness of radiation exposure and related protective practices among interns and residents. Methods: An online survey was conducted nationwide from June 3 to June 16, 2023, engaging 262 interns and 799 residents. Descriptive analyses were conducted to summarize the status of occupational radiation exposure and radiation protection practices. Results: Approximately 6% of interns and 18% of residents reported receiving personal dosimeters, and 6% and 20%, respectively, were registered as radiation workers. In contrast, compliance with personal radiation protection equipment, such as lead aprons and thyroid shields, exceeded 85% during tasks involving radiation exposure. On average, interns spent 7 months (standard deviation [SD], 2.1) and residents 8.1 months (SD, 4.8) in main departments with potential radiation exposure. While overall safety performance showed improvement, the provision of personal dosimeters and radiation worker registration remained low (14.7%, 16.6%). Conclusion Despite improvements in radiation protection education and the provision of personal protective equipment, the registration rate for radiation workers among interns and residents remains low. Ensuring these medical professionals are registered and managed as radiation workers is crucial for prioritizing their safety and well-being.

We report a case of a cardiac lipoma arising from the free wall of right atrium, which was diagnosed as the presumed source of angina by compressing the right coronary artery in a 54-year-old woman. Surgical excision of the tumor was performed well. She continues to do well for six months without angina.

The purpose of this study was to determine whether head posture affects three-dimensional (3D) facial images. This study evaluated facial images of 10 mannequins, which are taken from standard postures, left and right rotations, and up and down rotations. The images with changed head posture were superimposed onto standard head posture image, and the difference between the two images was used to evaluate deformations in images with the changed head postures. The 3D facial images showed considerable differences depending on different head positions.
