Multicenter Study
DNA and RNA Oxidative Damage and Mortality of Patients With COVID-19.
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) oxidative damage is associated with mortality of patients with different diseases. However, there are no data about DNA and RNA oxidative damage from coronavirus disease 2019 (COVID-19) patients. Thus, the objective of this study was to explore DNA and RNA oxidative damage in surviving and non-surviving COVID-19 patients. ⋯ To our knowledge, this is the first study reporting on oxidative DNA and RNA damage in COVID-19 patients, and the main new finding was that serum OGS concentration was associated with mortality.

Review Case Reports
Respiratory Failure Secondary to Diaphragmatic Paralysis from Acute Exacerbation of Dermatomyositis.
Dermatomyositis (DM) is an idiopathic inflammatory disorder that presents with proximal muscle weakness and typical DM skin changes. DM can involve other organs such as the lung, esophagus, and heart. Diaphragmatic muscle paralysis is an unrecognized clinical presentation of acute DM exacerbation. ⋯ The patient was worked up for an acute DM exacerbation as the likely etiology of the severe diaphragmatic muscle weakness (diaphragmatic paralysis) and ventilatory failure. Skin and muscle biopsy confirmed the diagnosis of active DM. The patient was treated with high dose steroids and mycophenolate mofetil, following which he soon recovered.

Review Case Reports
An Unusual Presentation of Adult-Onset Still's Disease in a Patient with Recurrent Pleural and Pericardial Effusions.
Adult-Onset Still's Disease (AOSD) usually presents with a salmon-colored skin rash and arthralgias. However, it can also be present with pleural and pericardial effusions. These effusions are often misdiagnosed as having an infectious etiology because AOSD usually present with fever, leukocytosis, elevated inflammatory markers, procalcitonin and CRP. ⋯ Patient was found to have an extremely high ferritin levels, whereby a diagnosis of AOSD was made after excluding infection, malignancy and other rheumatological disorders based on the Yamaguchi criteria. AOSD is a rare disease with unusual presentation and diagnosis is often delayed. This case aimed to raise awareness among physicians of the multifaceted presentation of AOSD.
