Objectives: This study aimed to describe the current public programs for community walking in Korea and to discuss their challenges.Method: We identified the literature related to community walking including five laws, 22 white papers from government departments and 84 program reports from the Seoul Metropolitan Government. Results: Korean law guarantees legal rights and validity to create safe, convenient and equitable environments for community walking. The government department, which has jurisdiction over legislation relating to community walking, has dominated community walking programs, and the role of public health department has been insufficient. Almost all sectors in the department of Seoul Metropolitan Government were involved in community walking programs. However, inter-sectoral cooperation system for community walking was insufficient. Conclusion It is necessary to revise the condolences of the National Health Promotion Act to establish the role and perspective of public health in community walking promotion. Institutional efforts should be made to expand the network structure between sectors of community walking programs by establishing an organizational, budget, and performance sharing system for inter-sectoral approach.

Background: Hematocrit is usually measured from venous blood collected by invasive venipuncture. This study was performed to determine hematocrit accurately and precisely using minimally invasive volumetric absorptive microsampling (VAMS) technique.Such technique is to be applied to determining hematocrit in various clinical settings for the care, including therapeutic drug monitoring, of neonatal or epileptic patients, or patients with high risk of infection or bleeding. Methods: The study was performed using 31 VAMS samples obtained from 21 pancreatic cancer patients. Hematocrit was determined using the values of potassium concentrations obtained from blood in VAMS tips (HctVAMS ). HctVAMS was compared with hematocrit measured from blood collected by venipuncture (HctVP ). The accuracy and precision of HctVAMS in comparison to HctVP were evaluated using BlandAltman plot, Deming regression and mountain plot. Results: Bland-Altman plot displayed a random scattering pattern of the differences between HctVAMS and HctVP with the mean bias of −0.010 and the 95% limit of agreement ranging from −0.063 to 0.044.Deming regression for HctVAMS and HctVP line demonstrated very small proportional and constant biases of 1.04 and −0.003, respectively. Mountain plot exhibited a narrow and symmetrical distribution of the differences with their median of −0.011 and central 95% range from −0.049 to 0.033. Conclusion Hematocrit was accurately and precisely determined using less invasive VAMS technique. Such technique appears to be applicable to determining hematocrit in situations that venipuncture is not favorable or possible.

Hepatobiliary involvement is a rare manifestation of Henoch-Schonlein purpura (HSP). HSP cases related to hepatitis A, B or C virus have been reported but little is known about HSP cases complicated by cholestatic hepatitis without underlying hepatobiliary disease. Here, we report a case of Henoch-Schonlein purpura presenting with cholestatic hepatitis. The patient presented with upper abdominal pain and cholestasis that developed characteristic purpura. The patient was treated conservatively by therapeutic fasting and nutritional support, and liver function recovered 7 weeks after admission.

Since mid-December of 2019, coronavirus disease 2019 (COVID-19) infection has been spreading from Wuhan, China. The confirmed COVID-19 patients in South Korea are those who came from or visited China. As secondary transmissions have occurred and the speed of transmission is accelerating, there are rising concerns about community infections. The 54-year old male is the third patient diagnosed with COVID-19 infection in Korea. He is a worker for a clothing business and had mild respiratory symptoms and intermittent fever in the beginning of hospitalization, and pneumonia symptoms on chest computerized tomography scan on day 6 of admission. This patient caused one case of secondary transmission and three cases of tertiary transmission. Hereby, we report the clinical findings of the index patient who was the first to cause tertiary transmission outside China. Interestingly, after lopinavir/ritonavir (Kaletra, AbbVie) was administered, β-coronavirus viral loads significantly decreased and no or little coronavirus titers were observed.

Hypersensitivity myocarditis may result from an allergic reaction to a variety of agents such as antibiotics, anticonvulsants and diuretics. A diagnosis of hypersensitivity myocarditis should be considered in any patient with an ongoing allergic reaction to a drug, evidence of peripheral eosinophilia, an appearance of new electrocardiographic changes, mildly elevated cardiac enzyme, mild cardiomegaly on chest X-ray or unexplained tachycardia. This condition is rarely recognized clinically although it is occasionally diagnosed on endomyocardial biopsy. We report a 25 year-old woman with hypersensitivity myocarditis, which was diagnosed by endomyo-cardial biopsy and successfully treated by immunosuppression therapy with corticosteroids.

OBJECTIVE: This study assessed the risk of acute allergic-like reactions (AARs) after extravascular administration of iodinated contrast media (ICM) in at-risk patients compared with that after intravascular ICM administration. MATERIALS AND METHODS: From July 2012 to January 2016, 264 patients with a history of moderate or severe reactions to ICM, with re-exposure to ICM intravascularly or extravascularly were included. The incidence of recurrent AARs after ICM re-exposure were assessed according to the administration routes by reviewing electronic medical records and comparison between the two routes. RESULTS: Among 264 patients, 244 patients had been subsequently exposed to ICM intravascularly, 7 patients via an extravascular route and 13 patients with dual re-exposure. Of 257 patients with intravascular ICM re-exposure, 87 (33.9%) had mild to severe recurrent AARs and 143 (19.5%) cases of recurrent AARs occurred among 733 cases of intravascular ICM re-exposure on a case-by-case basis. However, there was no case of recurrent ARR after extravascular administration of ICM in 20 patients (45 cases) with ICM administrated extravascularly. CONCLUSION: For high-risk patients with a history of moderate or severe reactions to ICM, AARs upon extravascular administration of ICM are significantly infrequent compared with intravascular ICM administration.

Background: The corner pocket (CP) approach for supraclavicular block (SCB) prevents ulnar nerve (UN) sparing due to needle proximity to the lower trunk. Improved ultrasound resolution has suggested that the intertruncal (IT) approach is a suitable alternative method. We compared efficiency of these two approaches on the UN blockade. Methods: Sixty patients were randomized to undergo SCB using the ultrasound-guided CP or IT approach. For lower trunk blockade, 10 ml of local anesthetic agents (1 : 1 mixture of 0.75% ropivacaine and 1% lidocaine) were injected in the CP (CP approach) or between the lower and middle trunks (IT approach). Additional 15 ml was injected identically to block the middle and upper trunks in both groups. Sensory and motor blockade was evaluated after intervention. Results: Complete sensory blockade (75.9% [22/29] vs. 43.3% [13/30], P = 0.023) and complete motor blockade (82.8% [24/29] vs. 50.0% [15/30], P = 0.017) of the UN at 15 min after SCB were significantly more frequent in the IT than in the CP group. Sensory block onset time of the UN was significantly shorter in the IT compared to the CP group (15.0 [10.0; 15.0] min vs. 20.0 [15.0; 20.0] min; P = 0.012). Conclusions The IT approach provided a more rapid onset of UN blockade than the CP approach. These results suggest that the IT approach is a suitable alternative to the CP approach and can provide faster surgical readiness.

Purpose: This study evaluated the diagnostic performance of contrast-enhanced voiding urosonography (ce-VUS) using a second-generation ultrasound contrast agent for the diagnosis of vesicoureteral reflux (VUR) and intrarenal reflux (IRR), and compared it with that of standard fluoroscopic voiding cystourethrography (VCUG). Methods: Thirty-two consecutive children from April to October 2019 were included in this study. ce-VUS and VCUG were performed simultaneously by two operators with intravesical infusion of a mixture of ultrasound contrast medium, iodinated contrast medium and water. Two pediatric radiologists independently reviewed the ce-VUS and VCUG images and reported the presence and degree of VUR (grades I-V), and the presence and type of IRR. Results: Twenty-seven of 63 urinary systems showed VUR. Interobserver agreement for VUR grading was very good for both examinations (κ=0.87; 95% confidence interval [CI], 0.82 to 0.92 for ce-VUS and κ=0.92; 95% CI, 0.87 to 0.96 for VCUG). The detection rate of VUR showed no significant difference between the two examinations (P=0.370). Four cases of VUR were missed on ce-VUS, while one case of VUR was missed on VCUG. All four false-negative cases on ce-VUS were grade 1 VUR. The two examinations showed very good agreement regarding VUR grading (κ =0.89; 95% CI, 0.81 to 0.96). IRR was more frequently detected with ce-VUS than with VCUG (10 cases with ce-VUS vs. 3 cases with VCUG, P=0.016). Conclusion ce-VUS showed very good agreement with VCUG for detecting grade 2 VUR and above, while grade 1 VUR was sometimes missed with ce-VUS. IRR was more frequently detected with ce-VUS than with VCUG.
