Inferior vena cava (IVC) thrombosis, a type of deep vein thrombosis (DVT), is a relatively rare and poorly known disease compared to lower extremity DVT. We present a case of a 68-year-old woman with abdominal pain and mild lower leg swelling due to IVC thrombosis extending from the common iliac vein to the infrahepatic IVC. The thrombus was removed using a 14-mm Niti-S stent (Taewoong Medical, Korea) inserted via the right internal jugular vein. The stent was partially deployed and gently advanced to cover the thrombus, and then retracted through a vascular sheath capturing the thrombus. This case presents a therapeutic approach for the treatment of IVC thrombosis using a half-deployed stent as a filter and a basket. Follow-up evaluation after 5 years revealed a patent IVC and common iliac vein.

A measles outbreak with 20 confirmed cases occurred at a local children’s hospital in Daejeon from March 28 to April 21, 2019. The index patient was a 7-month-old girl with a recent history of travel to Vietnam. Contact tracing, active surveillance, and post-exposure prophylaxis were conducted by health authorities. Among the 20 patients, 11 (55%) were infants (0–11 months of age), three (15%) were aged 1–3 years, one (5%) was aged 4 years, and five (25%) were adults. Fifteen (75%) patients did not have a history of measles vaccination, and five (25%) had received only one vaccine dose. This study described the importance of prompt application of infection control measures in susceptible environments, including hospitals. Age-appropriate vaccination and providing information on infectious diseases to international travelers and multicultural families in Korea is vital.

Purpose: As the coronavirus disease 2019 (COVID-19) pandemic ended, the number of patients with respiratory syncytial virus (RSV) pneumonia increased during the spring/summer of 2022.This study aimed to analyze the clinical features and antibiotic usage of children hospitalized for RSV pneumonia in a recently established general hospital in Sejong city. Methods: In this retrospective review, we included inpatients of the Pediatric Department of Chungnam National University Sejong Hospital diagnosed with RSV pneumonia between March 2022 and April 2023. Patients were divided into 2 groups: with and without antibiotic treatment. Demographic data, initial presentations, and clinical courses were reviewed. Results: A total of 116 patients with RSV pneumonia were hospitalized during this period, of which 102 were analyzed, excluding 14 with underlying diseases or who did not fall within the definition of pneumonia. The median age was 17 months. Diagnoses of bacterial infections (acute otitis media and sinusitis) were documented in 9.8% of cases. Intravenous (IV) antibiotics were administered in 46% of cases. The group receiving IV antibiotics showed higher inflammatory levels (C-reactive protein; CRP), more infiltration on initial chest X-rays, and longer fever duration. There was no difference in the length of hospitalization between the groups with and without IV antibiotics. Conclusions This study showed a tendency for the attending physician to prescribe IV antibiotics to patients with longer fever duration, pulmonary infiltrations on the initial chest X-ray, and higher CRP levels. However, given the high rate of IV antibiotic usage compared to previous studies, care should be taken in antibiotic use.

PURPOSE: This study aimed to identify changes in smart device usage trends of young children using two studies conducted in 2015-2016 and 2017 respectively. METHODS: We compared the data of the previous study of 130 children (Group A) and the new study of 162 children (Group B). The children and parents were recruited from kindergartens in Seoul and Guri/Namyangju cities. We used the “Parental questionnaire for smart device usage status.” RESULTS: There were some changes in the smart device usage in young children and parental perception. In the 2017 study, smart device usage time increased during weekends (P < 0.05) and the usage with siblings decreased (P < 0.05). In 2017, the smart device was mostly used when children had to be quiet without disturbing others (36.8%). No significant difference existed in the main purpose of use: watching video clips (79.3% vs 76.6%). Overall control of the usage was still largely exercised by mothers; however, when using applications, mothers still only helped the children on request (51.8% vs 49.7%). Regarding the effect of smart device on children, responses of “not knowing” decreased and “will be negative” and “will be positive” increased (P < 0.05). Additionally, most mothers thought that “Although the smart device is currently unnecessary, it will be needed in future” in 2017 (46.3%). CONCLUSION: Limiting the smart device usage time during the weekends and increasing parental involvements are recommended. Guidelines for smart devices usage in young children are also necessary considering the changes in parental attitudes in recognizing the smart device usage as unavoidable.

BACKGROUND: A number of studies have found associations between heavy metals and uterine fibroids, but the results are inconsistent. Here, we conducted this research to demonstrate the relationships between blood heavy metal concentrations and uterine fibroid volume as well as the rate of uterine fibroid presence. METHODS: In a cross-sectional study, we collected data from 308 premenopausal women aged 30–49 years in Seoul; uterine fibroids are ascertained by past history of myomectomy and pelvic ultrasonography. In the analytic phase, we first analyzed the presence of the fibroids and the concentrations of heavy metals via logistic regression. In subgroup analysis, we used simple and multiple linear regression analyses to examine the associations between heavy metals and uterine fibroid volume. RESULTS: There was no connection between the heavy metal concentrations and the presence of uterine fibroids, but the odds of women having fibroids were higher with three particular metals. In subgroup analysis, the association between blood cadmium concentrations and uterine fibroid volume was statistically significant (adjusted beta coefficient = 2.22, 95% confidential interval: 0.06–4.37). In contrast, blood mercury and lead concentrations were not significantly associated with uterine fibroid volume. CONCLUSIONS: Our findings are the first that we know to report the association of blood cadmium concentrations with the volume of uterine fibroids. We expect that our findings will be used as evidence for supporting policies to improve premenopausal Korean women's health.

Participation in a screening program by itself may not improve clinical outcomes. Treatment gaps in the program may limit its full benefit. We evaluated statin prescription rates for subjects with sustained hypercholesterolemia to assess the treatment gaps in the National Health Screening Program (NHSP) in Korea. A retrospective, random cohort was established among National Health Insurance Corporation (NHIC) members. Finally, we examined 465,499 individuals who attended the NHSP from 2003 to 2010 without any history of dyslipidemia, statin prescription, or hospitalization for cardiovascular events until the end of 2002. The subsequent statin prescription rates were identified from the NHIC medical service claim database from 2003 to 2011. Descriptive data and odds ratio from multivariate logistic analyses on statin prescription rates and the corresponding correlations were evaluated. The NHSP detected 114,085 (24.5%) cases of newly diagnosed hypercholesterolemia. However, only 8.6% of these received statin prescription within 6 months of diagnosis. For cases of sustained hypercholesterolemia determined in the next screening visit by the NHSP, the statin prescription rate increased, but only to 12.2%. Statin prescriptions were more common among females, older individuals, and hypertension or diabetes patients. Furthermore, the statin prescription rates had increased over the study period. The NHSP exhibited low statin prescription rate which has been improving. For the NHSP to be effective, it would be worthwhile to decrease the gap between the diagnosis of hypercholesterolemia and the following treatment.
