[Cardiac magnetic resonance imaging in patients with a suspected myocardial infarction and normal coronary arteries].
Patients hospitalized with suspected ST-segment elevation myocardial infarction (STEMI) who have normal coronary arteries (CAs) on invasive coronary angiography (ICA) may have an AMI or another acute cardiac disease that mimics it. ⋯ Cardiac magnetic resonance imaging allows a precise diagnosis of acute myocardial infarction in patients with angiographically normal coronary arteries.

Meta AnalysisThe Role of Hydroxychloroquine in COVID-19: A Systematic Review and Meta-Analysis.
A systematic review and meta-analysis was carried out to examine the role of hydroxychloroquine (HCQ) in the treatment of COVID-19. ⋯ The meta-analysis found that there was no clinical benefit of using either HCQ by itself or in combination with AZM for the treatment of COVID-19 patients. Hence, it may be prudent for clinicians and researchers to focus on other therapeutic options that may show greater promise in this disease.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the pathogen that causes coronavirus disease-2019 (COVID-19), is thought to be transmitted via droplets and aerosols, and was detected in saliva of infected individuals. These droplets from the upper airway may infect the inhalation sedation mask and tubing. The authors determined the adequate measures needed to prevent the transmission of COVID-19 by nitrous-oxide (N2O) system during inhalation sedation in dentistry and provided evidence on mask and tubing sterilization. ⋯ Biologic barriers should be mounted between the scavenger's tubing and the central evacuation system. Strict cleansing and sterilization should be performed for all parts of the N2O system. The use a disposable scavenger system and nasal mask should be considered as a viable option.

Histiocytic sarcoma (HS) is a rare hematopoietic malignancy originating from the monocyte/macrophage bone marrow lineage. HS can occur in isolation or in association with other hematological neoplasms such as non-Hodgkin lymphoma (NHL), myelodysplasia, or acute leukemia. Clinically, HS can affect lymph nodes, gastrointestinal tract, skin, bone marrow, and spleen as well as the central nervous system. Most cases of HS follow an aggressive clinical course, with most patients dying of progressive disease within one year of diagnosis.

ReviewCoronavirus Disease 2019 (COVID-19): The Singapore Experience. A Review of the First Eight Months.
As of 27 October 2020, there have been 57,980 confirmed cases of COVID-19 in Singapore, with 28 fatalities. To summarise the Singapore experience in managing and containing COVID-19 based on available published data and from relevant sources, a review of literature using research databases such as PubMed and OVID Medline, along with non-peer-reviewed articles and other sources, was conducted with the search terms 'COVID-19' and 'Singapore'. ⋯ Evidence of effectiveness of containment measures such as early border control, rigorous contact training, and calibrated social distancing measures have also been demonstrated. Singapore's multipronged strategy has been largely successful at containing COVID-19 and minimising fatalities, but the risk of re-emergence is high.
