RESUMO
To overcome the global pandemic of coronavirus disease 2019 (COVID-19), COVID-19 vaccination has been developed and distributed. Many people have received the vaccination worldwide. However, there are some vaccinated individuals who complain of side effects due to COVID-19 vaccination. We report the case of a patient who developed adult-onset Still’s disease (AOSD) after receiving the messenger RNA COVID-19 vaccine. A 21-year-old male patient without a previous medical history developed a fever on the day of the first dose of the vaccine. He had persistent fever, arthralgia of the knee and wrist, hyperferritinemia, transient skin rash, and negative test results for rheumatoid factor or antinuclear antibody. Positron emission tomography-computed tomography scan showed lymphadenopathies with reactive patterns and no malignancy. His symptoms and laboratory abnormalities gradually improved with glucocorticoid, cyclosporine, methotrexate, and tocilizumab treatment. Although its causality is still not confirmed, AOSD should be considered in a case that meets the diagnostic criteria after COVID-19 vaccination.
RESUMO
Background@#Remdesivir is widely used for the treatment of coronavirus disease 2019 (COVID-19), but controversies regarding its efficacy still remain. @*Methods@#A retrospective cohort study was conducted to evaluate the effect of remdesivir on clinical and virologic outcomes of severe COVID-19 patients from June to July 2020. Primary clinical endpoints included clinical recovery, additional mechanical ventilator (MV) support, and duration of oxygen or MV support. Viral load reduction by hospital day (HD) 15 was evaluated by calculating changes in cycle threshold (Ct) values. @*Results@#A total of 86 severe COVID-19 patients were evaluated including 48 remdesivirtreated patients. Baseline characteristics were not significantly different between the two groups. Remdesivir was administered an average of 7.42 days from symptom onset. The proportions of clinical recovery of the remdesivir and supportive care group at HD 14 (56.3% and 39.5%) and HD 28 (87.5% and 78.9%) were not statistically different. The proportion of patients requiring MV support by HD 28 was significantly lower in the remdesivir group than in the supportive care group (22.9% vs. 44.7%, P = 0.032), and MV duration was significantly shorter in the remdesivir group (average, 1.97 vs. 5.37 days; P = 0.017). Analysis of upper respiratory tract specimens demonstrated that increases of Ct value from HD 1–5 to 11–15 were significantly greater in the remdesivir group than the supportive care group (average, 10.19 vs. 5.36; P = 0.007), and the slope of the Ct value increase was also significantly steeper in the remdesivir group (average, 5.10 vs. 2.68; P = 0.007). @*Conclusion@#The remdesivir group showed clinical and virologic benefit in terms of MV requirement and viral load reduction, supporting remdesivir treatment for severe COVID-19.
RESUMO
As the number of people vaccinated increases, people who complain of adverse reactions continue to occur. We experienced a case characterized by low blood pressure, persistent fever, edema due to increased systemic vascular permeability, and systemic inflammation confirmed by image and laboratory examinations after ChAdOx1 coronavirus disease 2019 (COVID-19) vaccination. The diagnostic criteria for multisystem inflammatory syndrome (MIS) in adults are known as fever of 3 days or more in adults, 2 or more mucocutaneous/ gastrointestinaleurologic symptoms, elevation of inflammatory markers, and clinical/ imaging diagnosis of heart failure. A 67-year-old man who was medicated for hypertension and diabetes was admitted complaining of fever, maculopapular rash, diarrhea, headache, chills, and dizziness 6 days after the first vaccination of ChAdOx1 nCoV-19 in Korea.The COVID-19 test was negative but with low blood pressure, leukocytosis, skin rash, pulmonary edema, and increased inflammation markers. His lab findings and clinical course were consistent with those of MIS after COVID-19 vaccination. He was medicated with methylprednisolone 1 mg/kg and diuretics and recovered rapidly. He was discharged after 2 weeks and confirmed cure at outpatient clinic. We report an MIS case after COVID-19 vaccination in Korea.

RESUMO
This study aimed to evaluate the infectious disease (ID) physician workforce in Korea. We investigated the acquisition of ID physicians from 1992 to 2019 with their current working place in the Health Care System. We defined ID physicians working at general or tertiarycare hospitals as active ID physicians. A total 275 physicians acquired ID as a sub-specialty.Among the 275, 242 were active ID physicians. The density of active ID physicians was 0.47 per 100,000 population. Of all the 17 administrative districts, 11 (64.7%) fell short of 0.47, and 131 medical institutions employed the service of ID physicians. The median number of beds per adult ID physician was 372 (interquartile range, 280–507). It is essential to secure human resources to respond to emerging infectious diseases and perform the inherent work of ID physicians.
RESUMO
Background@#Carbapenemase-producing Enterobacteriaceae (CPE) are highly drug-resistant pathogens. Screening the contacts of newly-identified CPE patients is crucial for nosocomial transmission control. We evaluated the acquisition rate of CPE in close contacts as a function of CPE genotype. @*Materials and Methods@#This study was conducted in Asan Medical Center, a 2,700-bed, tertiary teaching hospital in Seoul, Korea, between November 2010 and October 2017. Index cases were defined as patients with positive tests for CPE from any infected or colonized site during hospitalization who had no direct epidemiologic linkage with existing CPE patients; close contact patients were defined as those whose hospital stay overlapped with the stay of an index case for at least one day and who occupied the same room or intensive care unit (ICU). Secondary patients were defined as those who produced positive CPE culture isolates from surveillance cultures that had the same CPE enzyme as that of the index case patients. @*Results@#A total of 211 index case patients and 2,689 corresponding contact patients were identified. Of the contact patients, 1,369 (50.9%) including 649 New-Delhi metallo-betalactamase-1 (NDM-1) and 448 Klebsiella pneumoniae carbaepenamse (KPC)-producing CPE exposures were screened, and 44 secondary patients (3.2%; 95% confidence interval 2.3 -4.3%) were positive for NDM-1-producing CPE (16 patients) and KPC-producing (24 patients) CPE. The CPE acquisition rate (5.4%) for KPC-producing CPE exposures was significantly higher than that for NDM-1 exposures (2.7%) (P = 0.01). @*Conclusion@#The CPE acquisition rate was 3.2% among close contacts sharing a multi-patient room, with about a two-fold higher risk of KPC-producing CPE than NDM-1-producing CPE.

RESUMO
To date, documentation of two doses of measles-containing vaccine (MCV) has been accepted as confirmation of measles immunity among healthcare workers (HCWs). However, we encountered measles in an HCW who had received two doses of MCV. A patient with measles was admitted to our hospital. Among 62 exposed HCWs, one nurse who had previously received two doses of MCV was shown to be negative for anti-measles immunoglobulin G (IgG), and was confirmed to have measles 14 days after exposure. Based on this experience, we suggest that all HCWs should be tested for anti-measles IgG to confirm their immunity to measles.
RESUMO
OBJECTIVES: During the outbreak of the Middle East Respiratory Syndrome (MERS) in Korea in 2015, the Korea Centers for Disease Control and Prevention (KCDC) confirmed a case of MERS in a healthcare worker in Daejeon, South Korea. To verify the precise route of infection for the case, we conducted an in-depth epidemiological investigation in cooperation with the KCDC. METHODS: We reviewed the MERS outbreak investigation report of the KCDC, and interviewed the healthcare worker who had recovered from MERS. Using the media interview data, we reaffirmed and supplemented the nature of the exposure. RESULTS: The healthcare worker, a nurse, was infected while performing cardiopulmonary resuscitation (CPR) for a MERS patient in an isolation room. During the CPR which lasted for an hour, a large amount of body fluid was splashed. The nurse was presumed to have touched the mask to adjust its position during the CPR. She suggested that she was contaminated with the MERS patient’s body fluids by wiping away the sweat from her face during the CPR. CONCLUSIONS: The possible routes of infection may include the following: respiratory invasion of aerosols contaminated with MERS-coronavirus (MERS-CoV) through a gap between the face and mask; mucosal exposure to sweat contaminated with MERS-CoV; and contamination during doffing of personal protective equipment. The MERS guidelines should reflect this case to decrease the risk of infection during CPR.

BACKGROUND: Dengue fever is one of the most dominant vector-borne diseases, putting approximately 3.9 billion people at risk worldwide. While it is generally vector-borne, other routes of transmission such as needlestick injury are possible. Laboratory workers can be exposed to dengue virus transcutaneously by needlestick injury. This is the first case, to our knowledge, of dengue virus infection by needlestick injury in a laboratory environment. This paper evaluates the risk and related health concerns of laboratory workers exposed to dengue virus. CASE PRESENTATION: We evaluated a 30-year-old female laboratory worker exposed to the dengue virus by needlestick injury while conducting virus filtering. During admission, she showed symptoms of fever, nausea, myalgia, and a characteristic maculopapular rash with elevated aspartate aminotransferase (AST) of 235 IU/L and alanine aminotransferase (ALT) of 269 IU/L. She had been diagnosed by a positive nonstructural protein 1 (NS1) antigen (Ag) rapid test one day prior to symptom onset along with positive immunoglobulin M (IgM) enzyme-linked immunosorbent assay (ELISA) on the ninth day of symptom onset. Reverse transcription polymerase chain reaction (RT-PCR), also conducted on the ninth day, was negative. After proper symptomatic treatment, she recovered without any sequelae. As a result of thorough epidemiologic investigation, it was determined that she had tried to recap the needle during the virus filtering procedure and a subsequent needlestick injury occurred. CONCLUSIONS: In the context of health promotion of laboratory workers, we suggest that the laboratory biosafety manual be revised and reinforced, and related prevention measures be implemented. Furthermore, health authorities and health care providers in Korea should be fully informed of proper dengue fever management.

Aesthetic impression is emphasized in the recent field of implant restoration. However, there is limitation of creating proper shape of soft tissue as well as cervical emergence profile due to the use of pre-existing healing abutment in the process of initial post-operative soft tissue healing period. Designing the shape of abutment into the final customized abutment instead of its original shape helped to achieve more aesthetic implant restoration by applying healing abutment which could minimize the malposition and recession of soft tissue. In this study, soft tissue healing was promoted using the post-operative customized healing abutment and thereby obtained the result of more aesthetic and functional restoration by minimizing displacement of soft tissue in the process of applying final customized abutment.
RESUMO
Methimazole and prophylthiouracil are commonly prescribed for patients with hyperthyroidism. The serious side effect of toxic hepatitis caused by these two drugs is well known. According to recent Korean and American management guidelines for hyperthyroidism, mehimazole is recommended as the first-choice antithyroid drug for the treatment of hyperthyroidism. Toxic hepatitis rarely occurs in methimazole users. We report a rare case of a 52-year-old female with toxic hepatitis after methimazole use that had past medical history of simvastatin induced liver injury.

Hepatic portal venous gas (HPVG) is a rare disease presenting as acute abdomen. The presence of the air in the portal vein has been associated with a mortality rate of more than 75%. Because of high mortality rate, most HPVG requires emergent surgical interventions and intensive medical management. HPVG is most commonly caused by mesenteric ischemia but may have a variety other causes. Clostridium perfringens is the most common pathogen of gas forming bacteria that can cause of HPVG, but Clostridium perfringens blood stream infection with HPVG is not yet reported in Korea. We experienced a case of HPVG caused by Clostridium perfringens blood stream infection at mesenteric venous hemangioma with portal hypertension due to mesenteric arteriovenous malformation.

The classic presentation of renal cell carcinoma (pain, hematuria, and flank mass) occurs in a minority of patients and often is indicative of advanced disease. Common sites of metastatic renal cell carcinoma are lung, soft tissues, bone, and liver. Paranasal sinus is an unusual site for metastasis of renal cell carcinoma. One 73-year-old male presented to Soonchunhyang University Seoul Hospital with melena. Renal cell carcinoma with metastasis to duodenum was diagnosed by computed tomography (CT). He underwent right radical nephrectomy and Whipple's operation. Positron emission tomography/CT was performed postoperatively, and then metastasis to maxillary sinus was found by accident. He was treated with molecular targeted therapy (pazopanib hydrochloride 800 mg).

ST-elevation myocardial infarction (STEMI) involving multivessel coronary arteries is extremely rare. Consecutive STEMI in a nonculprit vessel during primary percutaneous coronary intervention (PCI) of the culprit vessel has not been reported. A 53-year-old male presented to the emergency department with anterior wall STEMI. Just after successful primary PCI of the left anterior descending artery, inferior wall STEMI developed. PCI of the right coronary arteries was performed successfully. Five days later, the patient was discharged without symptoms of heart failure. This case underlines the high thrombogenicity along the coronary arteries in patients with STEMI.

Herbal remedies and health foods are widely used, and their side effects have been reported. Glucosamine is a naturally occurring amino-monosaccharide and a safe health food; rarely, however, it can cause cholestatic and hepatocellular hepatitis. We describe a case of drug-induced autoimmune hepatitis after ingestion of glucosamine. A middle-aged woman who had no history of liver disease complained of jaundice after taking glucosamine. The diagnosis of drug-induced acute autoimmune hepatitis was made using the Roussel Uclaf Causality Assessment Method score based on the patient's history and laboratory data, and percutaneous liver biopsy. After supportive care and administering prednisolone and azathiprine, the patient showed rapid improvement in clinical symptoms and laboratory findings.
