Background: and Purpose Recent studies suggested an increased incidence of cerebral venous thrombosis (CVT) during the coronavirus disease 2019 (COVID-19) pandemic. We evaluated the volume of CVT hospitalization and in-hospital mortality during the 1st year of the COVID-19 pandemic compared to the preceding year. Methods: We conducted a cross-sectional retrospective study of 171 stroke centers from 49 countries. We recorded COVID-19 admission volumes, CVT hospitalization, and CVT in-hospital mortality from January 1, 2019, to May 31, 2021. CVT diagnoses were identified by International Classification of Disease-10 (ICD-10) codes or stroke databases. We additionally sought to compare the same metrics in the first 5 months of 2021 compared to the corresponding months in 2019 and 2020 (ClinicalTrials.gov Identifier: NCT04934020). Results: There were 2,313 CVT admissions across the 1-year pre-pandemic (2019) and pandemic year (2020); no differences in CVT volume or CVT mortality were observed. During the first 5 months of 2021, there was an increase in CVT volumes compared to 2019 (27.5%; 95% confidence interval [CI], 24.2 to 32.0; P<0.0001) and 2020 (41.4%; 95% CI, 37.0 to 46.0; P<0.0001). A COVID-19 diagnosis was present in 7.6% (132/1,738) of CVT hospitalizations. CVT was present in 0.04% (103/292,080) of COVID-19 hospitalizations. During the first pandemic year, CVT mortality was higher in patients who were COVID positive compared to COVID negative patients (8/53 [15.0%] vs. 41/910 [4.5%], P=0.004). There was an increase in CVT mortality during the first 5 months of pandemic years 2020 and 2021 compared to the first 5 months of the pre-pandemic year 2019 (2019 vs. 2020: 2.26% vs. 4.74%, P=0.05; 2019 vs. 2021: 2.26% vs. 4.99%, P=0.03). In the first 5 months of 2021, there were 26 cases of vaccine-induced immune thrombotic thrombocytopenia (VITT), resulting in six deaths. Conclusions During the 1st year of the COVID-19 pandemic, CVT hospitalization volume and CVT in-hospital mortality did not change compared to the prior year. COVID-19 diagnosis was associated with higher CVT in-hospital mortality. During the first 5 months of 2021, there was an increase in CVT hospitalization volume and increase in CVT-related mortality, partially attributable to VITT.

Esophageal achalasia is a primary motility disorder characterized by insufficient lower esophageal sphincter relaxation and loss of esophageal peristalsis. Achalasia is a chronic disease that causes progressive irreversible loss of esophageal motor function. The recent development of high-resolution manometry has facilitated the diagnosis of achalasia, and determining the achalasia subtypes based on high-resolution manometry can be important when deciding on treatment methods. Peroral endoscopic myotomy is less invasive than surgery with comparable efficacy. The present guidelines (the “2019 Seoul Consensus on Esophageal Achalasia Guidelines”) were developed based on evidence-based medicine; the Asian Neurogastroenterology and Motility Association and Korean Society of Neurogastroenterology and Motility served as the operating and development committees, respectively. The development of the guidelines began in June 2018, and a draft consensus based on the Delphi process was achieved in April 2019. The guidelines consist of 18 recommendations: 2 pertaining to the definition and epidemiology of achalasia, 6 pertaining to diagnoses, and 10 pertaining to treatments. The endoscopic treatment section is based on the latest evidence from meta-analyses. Clinicians (including gastroenterologists, upper gastrointestinal tract surgeons, general physicians, nurses, and other hospital workers) and patients could use these guidelines to make an informed decision on the management of achalasia.

Ginseng products available in different forms and preparations are reported to have varied bioactivities and chemical compositions. In our previous study, four new dammarane-type ginsenosides were isolated from Panax ginseng, which are ginsenoside Rg18 (1), 6-acetyl ginsenoside Rg3 (2), ginsenoside Rs11 (3), and ginsenoside Re7 (4). Accordingly, the goal of this study was to determine the distribution and content of these newly characterized ginsenosides in different ginseng products. The content of compounds 1 – 4 in different ginseng products was determined via HPLC-UV. The samples included ginseng roots from different ginseng species, roots harvested from different localities in Korea, and samples harvested at different cultivation ages and processed under different manufacturing methods. The four ginsenosides were present at varying concentrations in the different ginseng samples examined. The variations in their content could be attributed to species variation, and differences in cultivation conditions and manufacturing methods. The total concentration of compounds 1 – 4 were highest in ginseng obtained from Geumsan (185 µg/g), white-6 yr ginseng (150 µg/g), and P. quinquefolius (186 µg/g). The results of this study provide a basis for the optimization of cultivation conditions and manufacturing methods to maximize the yield of the four new ginsenosides in ginseng.

In 2010, the Asian Society of Cardiovascular Imaging (ASCI) provided recommendations for cardiac CT and MRI, and this document reflects an update of the 2010 ASCI appropriate use criteria (AUC). In 2016, the ASCI formed a new working group for revision of AUC for noninvasive cardiac imaging. A major change that we made in this document is the rating of various noninvasive tests (exercise electrocardiogram, echocardiography, positron emission tomography, single-photon emission computed tomography, radionuclide imaging, cardiac magnetic resonance, and cardiac computed tomography/angiography), compared side by side for their applications in various clinical scenarios. Ninety-five clinical scenarios were developed from eight selected pre-existing guidelines and classified into four sections as follows: 1) detection of coronary artery disease, symptomatic or asymptomatic; 2) cardiac evaluation in various clinical scenarios; 3) use of imaging modality according to prior testing; and 4) evaluation of cardiac structure and function. The clinical scenarios were scored by a separate rating committee on a scale of 1–9 to designate appropriate use, uncertain use, or inappropriate use according to a modified Delphi method. Overall, the AUC ratings for CT were higher than those of previous guidelines. These new AUC provide guidance for clinicians choosing among available testing modalities for various cardiac diseases and are also unique, given that most previous AUC for noninvasive imaging include only one imaging technique. As cardiac imaging is multimodal in nature, we believe that these AUC will be more useful for clinical decision making.

48-year-old woman was admitted to emergency room due to left flank pain. It was diagnosed with left ureteral stone and underwent extracorporeal shock wave lithotripsy (ESWL). However, 12 hours later, the patient complained acute upper abdominal pain with pulmonary edema and low blood pressure. A diagnosis of moderate acute pancreatitis with local complication was considered and we decided conservative therapy including fluid resuscitation, inotropics and antibiotics. It was suggested that ESWL was responsible for the acute pancreatitis. The patient gradually recovered and was discharged on 13th day of admission. ESWL is considered the standard treatment for urolithiasis. Although, it has proved to be safe and effective, serious complications have been reported in 1% of patients, including acute pancreatitis, perirenal hematoma, urosepsis, venous thrombosis, biliary obstruction, bowel perforation, lung injury, and cardiac arrhythmia. Although the possibility of post-ESWL acute pancreatitis is extremely low, physicians should take care of this complication.

Stress cardiomyopathy is characterized by transient systolic dysfunction of the apical and/or mid segment of the left ventricle. The main pathophysiology of stress cardiomyopathy is the excessive release of catecholamine. Opioid withdrawal can initiate a surge of catecholamine and an attack of stress cardiomyopathy. In this case, we report a case of stress cardiomyopathy due to iatrogenic withdrawal from transdermal fentanyl.

An 87-yr-old woman was diagnosed with AML with myelodysplasia-related changes (AML-MRC). The initial complete blood count showed Hb level of 5.9 g/dL, platelet counts of 27x10(9)/L, and white blood cell counts of 85.33x10(9)/L with 55% blasts. Peripheral blood samples were used in all the tests, as bone marrow examination could not be performed because of the patient's extremely advanced age and poor general health condition. Flow cytometric analysis, chromosome analysis, FISH, and reverse transcriptase-PCR (RT-PCR) results indicated AML-MRC resulting from t(3;21) with the RUNX1-MECOM fusion gene. To our knowledge, this is the second most elderly de novo AML patient associated with t(3;21) to be reported.

A paradoxical embolism is defined as a systemic arterial embolism requiring the passage of a venous thrombus into the arterial circulatory system through a right-to-left shunt, and is commonly related to patent foramen ovale (PFO). However, coexisting pulmonary embolisms, deep vein thromboses (DVT), and multipe systemic arterial embolisms, associated with PFO, are rare. Here, we report a patient who had a cryptogenic ischemic stroke, associated with PFO, which is complicated with a massive pulmonary thromboembolism, DVT, and renal infarctions, and subsequently, the patient was treated using a thrombolytic therapy.

BACKGROUND: Chronic heart failure (HF) is a leading cause of morbidity and mortality in industrialized countries. Raised resting heart rate (HR) is a marker of cardiovascular risk in general population, as well as in patients with hypertension and coronary artery disease. We studied the association between HR and cardiovascular events in patients with Cardiac Insufficiency of Various Origin in Jeonbuk (CION-J) registry. METHODS: CION-J registry was a multicenter, prospective database for chronic HF. From January 2010 to December 2010, 356 HF patients who clinically stabilized at least 2 weeks were analyzed. According to resting HR, the patients divided into the tertile (lower tertile < 70/min, n = 129; middle tertile 70-80/min, n = 114; upper tertile > 80/min, n = 113). Clinical outcomes during 6-month period were compared by resting HR. RESULTS: Patients with upper tertile revealed higher New York Heart Association (NYHA) class than in those with lower tertile. From the lower to the upper tertile, the incidence of composite events of death, non-fatal myocardial infarction, ischemic stroke, and hospitalization for HF were increased(3.1%, 4.4%, 16.8%, respectively; p < 0.001). Patients with upper tertile had a higher predictive value for the incidence of death (hazard ratio, 5.8; p = 0.036) and hospitalization for HF (hazard ratio, 6.4; p < 0.001) than in those with middle and lower tertile. In multivariate analysis, NYHA class III/IV, resting HR > 80/min, and ejection fraction < 35% were independent predictors of adverse events. CONCLUSIONS: High resting HR (> 80/min) is a prognostic factor in chronic HF. Optimal treatment to reduce HR should be emphasized to improve prognosis of HF.
