Sociodemographic, laboratory, image data and predictors of gravity risk in patients with COVID-19.

INTRODUCTION: The effects, severity, and prognosis of COVID-19 infections do not follow a linear pattern in different locations, but change according to the epidemiological data and social issues in each region. AIMS: The purpose of the current study is to provide the clinical and epidemiological standard of the population affected by COVID-19 in the city of Juiz de Fora, MG to better understand the disease and its risk factors, in order to enable more appropriate conduct for patients. METHODS: A retrospective observational study was carried out from March to August of 2020, with 266 participants admitted to the emergency department of the Instituto de Clínicas e Cirurgia de Juiz de Fora-Hospital Monte Sinai. Data were tabulated, analyzed, and classified according to the outcome using an ordinal regression model. RESULTS: Among the 266 admitted patients, the most common findings were ground-glass opacifications on chest CT (78.8%), cough (75.6%), fever (58.4%), and rhinorrhea (34.5%). There were greater severity and greater need for hospitalization and admission to the ICU in patients who were male, tachypneic at the time of admission, with older age, and with underlying diseases. CONCLUSION: Collected data allowed for a better understanding of the disease, its severity criteria, and its pattern of affection in Juiz de Fora, MG. More studies based on the analysis of the behavior of COVID-19 in different regions must be carried out, to improve treatment and support to local populations.

Acute arterial occlusion of the lower limb as the main clinical manifestation in a patient with Covid-19 - Case Report.

INTRODUTION: COVID-19 infection may predispose to venous and arterial thromboembolism due to excessive inflammation, hypoxia, immobilization and disseminated intravascular coagulation; however, there are few reports of lower limb ischemia as the main manifestation of the disease. PRESENTATION OF CASE: Male patient, 69 years old, asthmatic, ex-smoker and bearer of systemic arterial hypertension, has been admitted to the emergency department with sudden onset of pain in the right lower limb (RLL), associated with cyanosis and reduced temperature of the limb. He has been tested for COVID-19 in the OR with positive result for IGG and IGM. Computed tomography angiography (AngioCT) was performed, showing signs of arterial embolization to both limbs, right internal iliac artery, and superior mesenteric artery. Faced with the threat of limb loss and the absence of signs and symptoms of visceral ischemia, the patient underwent full anticoagulation and RLL thromboembolectomy and tricompartmental fasciotomy. He was discharged after 7 days of hospitalization and demonstrated no other signs and symptoms of COVID-19, following outpatient follow-up. DISCUSSION: COVID-19 is associated with high risk of thrombotic complications being related to the clinical severity of the patient, with few studies that show symptoms of sudden pain in the lower limb without other complaints. CONCLUSION: Individuals infected with COVID-19 are at risk for arterial thromboembolic events, and knowledge of such cases is essential in order to create specific protocols for prophylaxis of thrombotic events in these patients, in addition to increasing the suspicion of infection in individuals with acute arterial occlusion, mostly during pandemic times.
