Long-term positive severe acute respiratory syndrome coronavirus 2 ribonucleic acid and therapeutic effect of antivirals in patients with coronavirus disease: Case reports
Abstract Coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been declared a pandemic. We herein report four COVID-19 cases with long-term positive viral ribonucleic acid (RNA) for about 61 days. Despite treatment with recombinant human interferon, convalescent plasma from COVID-19 patients, arbidol, etc., nucleic acid results were still positive for SARS-CoV-2. After treatment with ritonavir-boosted danoprevir (DNVr, 100/100 mg, once daily), all four patients showed two to three consecutive negative SARS-CoV-2 RNA and were thus discharged from hospital. Therefore...

Computed tomography findings in a Brazilian cohort of 48 patients with pneumonia due to coronavirus disease
CONCLUSIONS: The most common CT findings were ground-glass opacities and the crazy-paving pattern. Involvement was mostly bilateral, symmetrical, and peripheral. Round opacity morphology was frequently observed and might have some degree of specificity to viral COVID-19 pneumonia. (Source: Revista da Sociedade Brasileira de Medicina Tropical)

Confirmed Invasive Pulmonary Aspergillosis and COVID-19: the value of postmortem findings to support antemortem management
We present postmortem evidence of invasive pulmonary aspergillosis (IPA) in a patient with severe COVID-19. Autopsies of COVID-19 confirmed cases were performed. The patient died despite antimicrobials, mechanical ventilation, and vasopressor support. Histopathology and peripheral blood galactomannan antigen testing confirmed IPA. Aspergillus penicillioides infection was confirmed by nucleotide sequencing and BLAST analysis. Further reports are needed to assess the occurrence and frequency of IPA in SARS-CoV-2 infections, and how they interact clinically. (Source: Revista da Sociedade Brasileira de Medicina Tropical)

Exercise tests in Chagas cardiomyopathy: an overview of functional evaluation, prognostic significance, and current challenges
Abstract Patients with Chagas cardiomyopathy (ChC) usually progress with fatigue and dyspnea. Exercise tests are valuable for the functional evaluation of these patients. However, information about the applicability of the exercise tests is scattered, and no studies have systematically reviewed the results. Thus, the present review explored the general aspects and prognostic value of exercise tests in patients with ChC. A literature search of the MEDLINE, Web of Science, CINAHL, Scopus, and LILACS databases was performed to identify relevant studies. There were no data restrictions, and articles that met the objective of t...

A new case of envenomation by neotropical opisthoglyphous snake Philodryas olfersii (Lichtenstein, 1823) in Recife, State of Pernambuco, Brazil
Abstract Human envenomation by the snakes Colubridae and Dipsadidae are reported in Brazil, and envenomation by the Opisthoglyphous snake Philodryas olfersii could be dangerous. Here, we present the second record of an envenomation by Philodryas olfersii in Pernambuco, northeast Brazil. The male victim presented with mild erythema pain, paraesthesia, local numbness, and swollen lymph nodes. The symptoms were similar to those of a pit viper bite, and disappeared completely after 15 days. (Source: Revista da Sociedade Brasileira de Medicina Tropical)

Clinical repercussions of Glanders (Burkholderia mallei infection) in a Brazilian child: a case report
We report the case of an 11-year-old boy who was presented to an emergency department with chest pain and dyspnea. He evolved into septic shock, pneumonia, and multiple abscesses. B. mallei was found in the exudate culture. Human infection is rare and difficult to confirm. The knowledge on glanders is important for differential diagnosis from other serious illnesses causing pneumonia and multiple abscesses. (Source: Revista da Sociedade Brasileira de Medicina Tropical)
