Hyponatremia in Coronavirus Disease-19 Patients: A Retrospective Analysis.

Background: Hyponatremia (serum Na < 135 mmol/L) is the most common electrolyte abnormality detected in clinical practice and an important cause of mortality and morbidity in hospital settings. Hyponatremia in patients with pneumonia is usually mild but is associated with increased risk of intensive care unit (ICU) admission, prolonged hospital stays, and increased mortality rates. The purpose of this study is to understand the impact of varying degrees of hyponatremia and various other inflammatory markers on the severity and outcome of coronavirus disease-19 (COVID-19).

Pneumomediastinum in COVID-19: A series of three cases and review of literature.

Coronavirus disease-19 caused by severe acute respiratory syndrome Corona virus-2 is characterised by wide heterogeneity in clinical presentation. The typical radiographic findings in COVID-19 include bilateral ground-glass opacities and/or consolidations predominantly affecting the lower lobes and posterior segments of lungs. Other rare abnormal radiographic findings include pneumothorax, pneumomediastinum and pneumopericardium.

Posterior reversible encephalopathy syndrome as the first manifestation of mixed connective tissue disorder: a case report.

Background: Posterior reversible encephalopathy syndrome (PRES) is a neurological syndrome characterised by a range of neurological symptoms and signs, and distinctive neuroimaging findings reflecting vasogenic oedema. Posterior reversible encephalopathy syndrome has been described in association with many autoimmune diseases, but its association with mixed connective tissue disorder (MCTD) is very rare. After an extensive review of the literature, we found only three cases of posterior reversible encephalopathy syndrome in association with mixed connective tissue disorder.
