Postperfusion syndrome, also known as "pumphead", is a constellation of neurocognitive impairments attributed to cardiopulmonary bypass (CPB) during cardiac surgery. ...
AL amyloidosis is caused by the deposition of abnormal antibody free light chains. The abnormal light chains are produced by monoclonal plasma cells, and, although AL amyloidosis can occur without diagnosis of another disorder, it is often associated with other plasma cell disorders, such as multiple myeloma and Waldenström's macroglobulinemia.

Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process.
This contrasts with the pseudofusion beat wherein the pacemaker impulse does not affect the complex of the natural beat of the heart. Pseudofusion beats are normal. Rare or isolated fusion beats caused by pacemakers are normal as well, but if they occur too frequently may reduce cardiac output and so can require adjustment of the pacemaker. [3]
The most vulnerable cells in the brain, CA1 neurons of the hippocampus, are fatally injured by as little as 10 minutes without oxygen. However, the injured cells do not actually die until hours after resuscitation. [8] This delayed death can be prevented in vitro by a simple drug treatment even after 20 minutes without oxygen. [9]
CHS is exhibited typically as a congenital disorder, but in rare circumstances, can also result from severe brain or spinal trauma or injury (such as after an automobile accident, stroke, asphyxiation, brain tumor, encephalitis, poisoning, as a complication of neurosurgery) or due to particular neurodegenerative conditions such as Parkinson's disease, multiple system atrophy, or multiple ...
The pathophysiology of type 3 respiratory failure often includes lung atelectasis, which is a term used to describe a collapsing of the functional units of the lung that allow for gas exchange. Because atelectasis occurs so commonly in the perioperative period, this form is also called perioperative respiratory failure.
The Berlin definition included ALI as a mild form of ARDS. [53] However, the criteria for the diagnosis of ARDS in the Berlin definition excludes many children, and a new definition for children was termed pediatric acute respiratory distress syndrome (PARDS); this is known as the PALICC definition (2015).
