A case report, bilateral spontaneous pneumothorax as a late complication for SARS CoV-2 infection.

The beta-coronavirus discovered in Wuhan in 2019 (COVID-19) provokes a series of affections from mild symptoms to life-threatening complications. There is evidence that associates the disease to spontaneous pneumothorax, however, the mechanism is unknown. The patient was a 45-year-old male with previous pneumonia due to COVID-19 who was attended the emergency department, where chest radiography was taken, confirming the diagnosis of right pneumothorax.

Temporal relationship of serum markers and tissue damage during acute intestinal ischemia/reperfusion.

Objective: It is essential to identify a serological marker of injury in order to study the pathophysiology of intestinal ischemia reperfusion. In this work, we studied the evolution of several serological markers after intestinal ischemia reperfusion injury in rats. The markers of non-specific cell damage were aspartate aminotransferase, alanine aminotransaminase, and lactic dehydrogenase, the markers of inflammation were tumor necrosis factor alpha, interleukin-6, and interleukin-1 beta, and the markers of intestinal mucosal damage were intestinal fatty acid binding protein and D-lactate.
