Severe re-expansion pulmonary edema despite incomplete re-expansion of the lung: a case report.

Background: Re-expansion pulmonary edema is a rare but potentially fatal (mortality up to 20%) complication of the rapid removal of air, fluid, or other space-occupying lesion from the pleural cavity. This case report highlights the fact that this complication is much more likely to occur when treating large, chronic pneumothoraces, and can occur even if the lung fails to fully re-expand.

Case Presentation: A 49-year-old white British man presented to the emergency department with sudden onset of shortness of breath 5 days prior to admission.

Nitric oxide alters arachidonic acid turnover in brain cortex synaptoneurosomes.

Nitric oxide (NO) and arachidonic acid (AA) and also its metabolites are very important inter- and intracellular second messengers. They are involved in mechanisms of learning and memory. However, liberated in excessive amount in brain ischemia, Parkinson and Alzheimer diseases they are responsible for cell degeneration and death.
