Clinical application of multicolor imaging in central serous chorioretinopathy
Purpose: To characterize features of central serous chorioretinopathy (CSC) using multicolor (MC) imaging and to compare the efficacy of using MC imaging and traditional color fundus photography (CFP) for detecting features of CSC. Methods: A retrospective review of 75 eyes of 69 participants with CSC from the Eye Center of the Renmin Hospital of Wuhan University. The patients underwent same-day CFP, fundus fluorescein angiography (FFA), spectral domain optical coherence tomography (SD-OCT), and MC imaging (including infrared reflectance (IR), green reflectance (GR), blue reflectance (BR), combined standard MC image, and green-blue–enhanced image). Positive CSC lesions were evaluated using FFA and SD-OCT. Features in images of CFP, standard MC, green-blue–enhanced, IR, GR, and BR were analyzed and calculated. Results: Among the 75 eyes of 69 patients, 75 eyes with subretinal fluid (SRF) and retinal pigment epithelial (RPE) leakage point, and 43 eyes with RPE damage were observed by FFA and SD-OCT. The detection rate of SRF was significantly higher with the standard MC image (92.0%), green-blue–enhanced image (92.0%), IR (88.0%), and GR (88.0%) than that with CFP (66.7%) (P
By MICHEL ACCAD Last month marked the 400th anniversary of the birth of John Graunt, commonly regarded as the father of epidemiology. His major published work, Natural and Political Observations Made upon the Bills of Mortality, called attention to the death statistics published weekly in London beginning in the late 16th century. Graunt was skeptical of how causes of death were ascribed, especially in times of plagues. Evidently, 400 years of scientific advances have done little to lessen his doubts! A few days ago, Fox News reported that Colorado governor Jared Polis ...
We report on clinical and biochemical features of these patients. They were all males, with a mean age of 70.3 years (range 58–84); traditional risk factors for venous thromboembolism were identified in the majority of patients with pulmonary embolism, however not differently from those without pulmonary embolism.

We read with enormous interest the recent article by D.C. Rotzinger et.al entitled “Pulmonary embolism in patients with COVID-19: Time to change the paradigm of computed tomography” wherein they discussed and advocated the use of computed tomographic angiography (CTA) in patients of severe COVID-19 with clinical suspicion of pulmonary embolism (PE) . However, the idea of li beral use of CTA in every severe COVID-19 pneumonia with suspected PE may not be feasible in many situations in the current pandemic context and thus we must look for easy alternatives which can reliably aid in the diagnosis and management of PE.

We report a 41-year-old woman presented to emergency department with sudden death during physical activity. She had only history of diabetes mellitus and she was asymptomatic until sudden death. CT pulmonary angiography and chest CT scans revealed acute massive embolism and typical imaging findings of COVID-19 pneumonia, respectively. Interestingly, the patient had no symptoms or signs of infection and also had no risk factors for thromboembolism. COVID-19 infection appears to induce venous thromboembolism, especially pulmonary embolism. The case is remarkable in terms of showing how insidious and life-threatening COVID-19 infection can be.

Human coronavirus-associated myocarditis is known, and a number of COVID-19-related myocarditis cases have been reported. The pathophysiology of COVID-19-related myocarditis is thought to be a combination of direct viral injury and cardiac damage due to the host ’s immune response. COVID-19 myocarditis diagnosis should be guided by insights from previous coronavirus and other myocarditis experience. The clinical findings include changes in ECG, cardiac biomarkers, and impaired cardiac function. When cardiac MRI is infeasible, cardiac CT angiography with d elayed myocardial imaging may serve to exclude significant cor...
