Lemierre syndrome is a rare disease involving multiple organs affected by septic emboli following oropharyngeal infection. After the introduction of penicillin in the 1940s, it became a "forgotten" disease. However, due to the development of diagnostic image modalities including neck computed tomography (CT) scan, the number of published reports of Lemierre syndrome and diagnosis has been increasing since the 1990s. In this report, we describe a case of Lemierre syndrome, following oropharyngeal infection in a 16-year-old patient, who manifested with persistent fever and neck stiffness. Neck ultrasonography confirmed thrombus formation in the right internal jugular vein without definite evidence of septic emboli to other organs. After the three-week-long antibiotics therapy was completed, the thrombus in the right internal jugular vein finally disappeared.

Korean Journal of Family Medicine 2020;41(6):374-380
Background:
Sedentary behavior is associated with increased cardiovascular disease (CVD) risk. We investigated this association of sedentary time and physical activity with increased 10-year CVD risk in Korean adults.
Methods:
This cross-sectional study used data from the Korea National Health and Nutrition Examination Survey (2014–2017). In total, 14,551 participants aged 30–74 years (6,323 men, 8,228 women) were analyzed. The usual length of sedentary time per day was categorized into three groups (<6, 6–<9, or ≥9 h/d), and physical activity (metabolic equivalents [METs]∙min/wk) was categorized into two groups (low, <600 METs∙min/wk; moderate/high, ≥600 METs∙min/wk). Logistic regression analysis was performed to assess the association between sedentary time and increased CVD risk (predicted 10-year risk ≥10%). Adjusted variables were age, sex, body mass index, marital status, employment, household income, alcohol use, family history of CVD, and comorbidity (hypertension, diabetes, and dyslipidemia).
Results:
The average sedentary time for the 14,551 participants was 7.49 h/d, with an average 10-year CVD risk of 9.58%. There was no significant association between sedentary time and increased 10-year CVD risk in the moderate/ high physical activity group. In the low physical activity group, sedentary time ≥9 h/d had a significant association with increased CVD risk (odds ratio [OR], 1.29; 95% confidence interval [CI], 1.04–1.62). However, when the sedentary time was <6 h/d, no significant associations were found (OR, 1.17; 95% CI, 0.92–1.49).
Conclusion
In the low physical activity group, reduction of sedentary time might be important for preventing increased CVD risk.

Health Policy and Management 2020;30(3):326-334
Background:
Korea has gradually expanded the coverage of medical care services in its national health insurance system. On April 1, 2018, it implemented a policy that expanded the coverage for an ultrasonography in the upper abdomen. In this study, we aimed to investigate the effect of the policy on the utilization of the ultrasonography in the upper abdomen in tertiary care hospitals.
Methods:
Using the dataset of the Health Insurance Review and Assessment Service, we explored changes in the utilization of the ultrasonography in the upper abdomen in tertiary care hospitals from July 1, 2017 to November 30, 2018 through the difference-in-difference (DID) mixed-effects-model method. Facility factor, equipment factor and personnel factors, type of hospital, the total amount of medical care expenses, and geographic region were considered as control variables.
Results:
On average, the utilization of the ultrasonography in the upper abdomen increased by 228% after the coverage expansion policy. However, the results of DID mixed-effects-model method analysis showed that the utilization increased by 73%. As for the number of beds, the utilization was higher with a group of 844–930, 931–1,217, and 1,218 or greater compared with a group of 843 or fewer, while the utilization of the number of ultrasonic devices was lower with a group of 45–49 compared with a group of 44 or fewer. The utilization decreased with the number of interns and the number of nurse assistants. Besides, relative to Seoul, the utilization was lower in the other metro-cities and provinces.
Conclusion
The coverage expansion policy in the national health insurance system increased service utilization among people. Future research needs to investigate the degree to which such coverage expansion policy reduces the unmet medical care needs among the deprived in Korea.
4.Comparison of Healthy Life Style and Chronic Disease Management between Urban and Rural Older Adults.
Korean Journal of Rehabilitation Nursing 2012;15(2):100-108
PURPOSE: The purpose of this study was to compare healthy life style and chronic disease management between urban and rural older adults. METHODS: The study employed a comparative and descriptive survey design. Data were collected from 154 older adults living independently in communities (79 from urban and 75 from rural areas) using structured questionaries from 24 July, 2010 to 14 August, 2011. RESULTS: Perceived health status was significantly lower in urban older adults than those in rural areas (chi2=13.27, p = .001). Frequency of regular health examination was better in the urban group than the rural group (chi2=4.71, p = .030). Among older adults with hypertension, medication noncompliance was higher, and participation rate in disease management education was lower in the rural group than the urban group (chi2=6.43, p = .040; chi2=23.51, p<.001, respectively) and the same as arthritis. CONCLUSION: Rural older adults had more problems with health and disease management in this study, might be, due to difficulties in access to health care services than urban residents. More tailored programs of disease management as well as health service programs and staffing should be developed in rural areas. For urban older adults, meal preparation program and more opportunities producing income may be needed.

Background:
The main barrier to the effective rheumatoid arthritis (RA) therapy is poor adherence. Coronavirus disease 2019 (COVID-19) pandemic have led to a significant change in the pattern and the number of medical visits. We assessed changing patterns of medical visits and no-show, and identified factors associated with no-show in patients with RA during COVID-19 pandemic.
Methods:
RA patients treated with disease-modifying antirheumatic drugs at least 6 months who had been in remission or those with mild disease activity were observed for 6 months from February to July 2020. No-show was defined as a missed appointment that was not previously cancelled by the patient and several variables that might affect no-show were examined.
Results:
A total of 376 patients and 1,189 appointments were evaluated. Among 376 patients, 164 patients (43.6%) missed appointment more than one time and no-show rate was 17.2% during COVID-19 pandemic. During the observation, face-to-face visits gradually increased and no-show gradually decreased. The logistic regression analysis identified previous history of no-show (adjusted odds ratio [OR], 2.225; 95% confidence interval [CI], 1.422–3.479; P < 0.001) and fewer numbers of comorbidities (adjusted OR, 0.749; 95% CI, 0.584–0.961; P = 0.023) as the independent factors associated with no-show.
Conclusion
Monthly analysis showed that the no-show rate and the pattern of medical visits gradually changed in patients with RA during COVID-19 pandemic. Moreover, we found that previous history of no-show and fewer numbers of comorbidities as the independent factors associated with no-show.

BACKGROUND: Recently, carbon fibers have been utilized to develop a depth-type microelectrode array for chronic neural recording. Since the diameter of carbon fibers is smaller than the conventional electrodes made of metal wires or microfabricated silicon, the carbon fiber electrodes showed an improved capability for chronic neural recording with less tissue damages. However, the carbon fiber based microelectrodes have a limitation of short insertion depth due to a low stiffness. METHODS: We proposed a carbon fiber based microelectrode array embedded with a mechanical support structure to facilitate the penetration into the deeper brain. The support is made of biodegradable silk fibroin to reduce the reactive tissue responses. The 4-channel carbon fiber based microelectrode arrays were fabricated and accessed in terms of electrochemical impedance, recording capability for 1-month implantation in rat hippocampi. The electrodes with tungsten supports were fabricated and tested as a control group. Immunohistochemical analysis was performed to identify the reactive glial responses. RESULTS: The carbon fiber based electrode arrays with silk supports showed about 2-fold impedance increase 2 weeks after implantation while the number of active electrodes decreased simultaneously. However, after 1 month, the electrode impedance decreased back to its initial value and the percentage of active electrodes also increased above 70%. Immunohistochemical staining clearly showed that the electrodes with silk supports induced less reactive glial responses than that with tungsten supports. CONCLUSION: The proposed carbon fiber based microelectrode array is expected to be used for long-term in vivo neural recording from deep brain regions with the minimized reactive tissue response.

PURPOSE: The purpose of this study was to evaluate the food insecurity status and dietary behavior and examine the association between the food insecurity status and consumption of processed beverage for secondary school students in Vientiane, capital city of Lao PDR. METHODS: The study subjects are 714 students (boys = 307 and girls = 407) in four secondary schools (Chao_Anouvong, Phiavat, Saysetha, and Chansavang) of Vientiane, Lao PDR. Data on study subject's demographic characteristics, dietary behavior, food insecurity, and Mini Dietary Assessment (MDA) index were collected. A “Self-Administered Food Security Survey Module for Children Aged 12 Years and Older” developed by the United States Department of Agriculture (USDA) was used for the food insecurity assessment. RESULTS: As a result, 72.7% of the subjects were in a state of food insecurity, and food security was associated with higher socioeconomic status (higher life satisfaction, higher parent's education attainment, higher item ownership, fewer number of siblings, and having more lunches at the school restaurant than at home). Compared to the food insecurity group, the frequency of breakfast, self-rated diet, and the total score of MDA index were higher in the food security group. On the other hand, multiple logistic regression analysis showed that ‘food security’ was also associated with a higher consumption of processed beverages (OR 1.544; 95% CI 1.078–2.213; p = 0.018). CONCLUSION: Improving the quality of the diet is essential for adolescents in both the food insecurity and food security groups in Lao PDR. Therefore, it is necessary to provide well organized nutrition education and establish adequate nutrition policy for adolescents in Lao PDR.

Annals of Pediatric Endocrinology & Metabolism 2021;26(2):105-111
Purpose:
Osteoporosis is a skeletal disorder characterized by reduced bone mass that results in increased risk of fractures. Pediatric osteoporosis can be caused by monogenic diseases, chronic diseases, and/or their treatment. This study was performed to investigate the effect of pamidronate infusion on osteoporosis in children and adolescents.
Methods:
This study included 13 unrelated pediatric patients (10 males and 3 females) whose bone mineral density (BMD) z-score was <-2.0. Pamidronate was administered intravenously at a dosage of 1 mg/kg for 3 consecutive days every 4 months. Clinical and biochemical findings were reviewed retrospectively. The BMD values of the lumbar spine and femoral neck were assessed by dual energy x-ray absorptiometry at baseline and annually.
Results:
The underlying diseases were immobilization (62%), inflammatory bowel disease (23%), protein-losing enteropathy (8%), and idiopathic juvenile osteoporosis (8%). The mean age at the start of treatment was 12.7±4.3 years. Duration of treatment ranged from 12–50 months. The baseline height-standard deviation score (SDS) and weight-SDS were -2.01±2.08 and -2.60±1.62, respectively. The lumbar spine BMD z-scores improved significantly after 1 year of pamidronate treatment, but the femoral neck BMD z-scores did not. However, both z-scores had significantly increased by the end of treatment.
Conclusion
This study demonstrated that pamidronate treatment increased BMD in pediatric patients with osteoporosis with no significant adverse events. Further studies are required to better define the long-term efficacy and safety of pamidronate therapy in a large number of pediatric patients.
