Halo, Reversed Halo, or Both? Atypical Computed Tomography Manifestations of Coronavirus Disease (COVID-19) Pneumonia: The "Double Halo Sign".

Halo, Reversed Halo, or Both? Atypical Computed Tomography Manifestations of Coronavirus Disease (COVID-19) Pneumonia: The "Double Halo Sign". Korean J Radiol. 2020 Jul 17;: Authors: Poerio A, Sartoni M, Lazzari G, Valli M, Morsiani M, Zompatori M Abstract The epidemic of 2019 novel coronavirus, later named as coronavirus disease (COVID-19), began in Wuhan, China in December 2019 and has spread rapidly worldwide. Early diagnosis is crucial for the management of the patients with COVID-19, but the gold standard diagnostic test for this infection, the reverse transcriptase polymerase chain reaction, has a low sensitivity and an increased turnaround time. In this scenario, chest computed tomography (CT) could play a key role for an early diagnosis of COVID-19 pneumonia. Here, we have reported a confirmed case of COVID-19 with an atypical CT presentation showing a "double halo sign," which we believe represents the pathological spectrum of this viral pneumonia.

As an emerging infectious disease, coronavirus disease 2019 (COVID-19) pneumonia, which is caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in a severe global public health emergency. According to the World Health Organization (WHO) COVID-19 epidemic interactive dashboard, as of 19 June 2020, there have been 8 385 440 confirmed cases all over the world, including 450 686 deaths. Under such urgent conditions, it is of great clinical significance to distinguish patients with poor clinical outcome (such as severe, critical or death) from within the large number of patients with COV...

AbstractPurpose of ReviewIn December 2019, outbreaks of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected pneumonia patients were discovered in Wuhan City, Hubei Province, China. With the spread of the epidemic, new cases have been found in other regions of China and abroad. This review summarizes the current coronavirus disease 2019 (COVID-19) transmission pathways, high-risk factors, diagnostic points, pathogenesis, and therapeutic drugs to provide the prevention and treatment theories for COVID-19.Recent FindingsCOVID-19 is highly contagious and is transmitted mainly through the respiratory tract.

i-Long Chen Some coronaviruses are zoonotic viruses of human and veterinary medical importance. The novel coronavirus, severe acute respiratory symptoms coronavirus 2 (SARS-CoV-2), associated with the current global pandemic, is characterized by pneumonia, lymphopenia, and a cytokine storm in humans that has caused catastrophic impacts on public health worldwide. Coronaviruses are known for their ability to evade innate immune surveillance exerted by the host during the early phase of infection. It is important to comprehensively investigate the interaction between highly pathogenic coronaviruses and their hosts. In th...

Coronavirus disease 2019 (COVID-19), an acute onset pneumonia caused by a novel Betacoronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in the Wuhan City of China in December 2019 and evolved into a global pandemic. To date, there are no proven drugs or vaccines against this virus. Hence, the situation demands an urgent need to explore all potential therapeutic strategies that can be made available to prevent the disease progression and improve patient outcomes. In absence of clinically proven treatment guidelines, several repurposed drugs and investigational agents are currently being evalua...

Conclusion Homoeopathy is a natural system of healing the ailing humans from diseases and an unquestioned method of detoxifying/antidoting the chemotherapeutic effects that render the human body susceptible to vague/novel diseases. Today, the challenge lies not only in diagnosis, but also in management of complexities in presentations of novel diseases and in restricting the transformation of simple infections into deadly outbreaks. Realisation of natural principles of healing is the urgent need. [...] Thieme Medical and Scientific Publishers Private Ltd. Article in Thieme eJournals: Table of contents  |&nbs...

AbstractThe epidemic phase of Coronavirus disease 2019 (COVID-19) made the Worldwide health system struggle against a severe interstitial pneumonia requiring high-intensity care settings for respiratory failure. A rationalisation of resources and a specific treatment path were necessary. The study suggests a predictive model drawing on clinical data gathered by 119 consecutive patients with laboratory-confirmed COVID-19 admitted in Busto Arsizio hospital. We derived a score that identifies the risk of clinical evolution and in-hospital mortality clustering patients into four groups. The study outcomes have been compared ac...

A novel pneumonia of unknown cause was detected in Wuhan, China, which was later named as Corona Virus Disease 2019 (COVID-19) by the World Health Organization (WHO), and the virus that caused this epidemic was named as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) [1].The outbreak of COVID-19 swept across China has aroused global concerns. As of May 5, 2020, more than 3.6 million COVID-19 cases have been confirmed around the world. According to different retrospective studies, among the patients with COVID-19, the case-fatality rate has huge variation [2,3].

Background: Novel coronavirus pneumonia (COVID-19) has become a worldwide epidemic, causing huge loss of life and property. Because of its unique pathological mechanism, diabetes affects the prognosis of patients with COVID-19 in many aspects. At present, there are many controversies about whether angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEI/ARB) should be used in the treatment of patients with diabetes mellitus and COVID-19 comorbidities. There is an urgent need to provide evidence for the use of ACEI/ARB through high-quality systematic evaluation and meta-analysis. Methods: We will se...

Over the past few years, Professor Zhang Yongzhen has made it his business to sequence thousands of previously unknown viruses. But he knew straight away that this one was particularly nasty. It was about 1:30 p.m. on Jan. 3 that a metal box arrived at the drab, beige buildings that house the Shanghai Public Health Clinical Center. Inside was a test tube packed in dry ice that contained swabs from a patient suffering from a peculiar pneumonia sweeping China’s central city of Wuhan. But little did Zhang know that that box would also unleash a vicious squall of blame and geopolitical acrimony worthy of Pandora herself....
