Pneumorrhachis with Spontaneous Pneumomediastinum: Should It Raise Special Concerns?

Spontaneous Pneumomediastinum with Concurrent Pneumorrhachis

Spontaneous pneumomediastinum is a very uncommon entity that is defined as the presence of free air in the mediastinum without an obvious etiology. The presence of air in the spinal canal, known as concurrent pneumorrhachis, is an extremely rare epiphenomenon of spontaneous pneumomediastinum. We report a rare case of spontaneous pneumomediastinum with pneumorrhachis associated with influenza. T...

An Unusual Association in an Uncommon Disease: Two Cases of Spontaneous Pneumomediastinum Associated with Pneumorrhachis

Pneumomediastinum, the presence of free air in the mediastinum, is described as spontaneous pneumomediastinum when there is no apparent cause such as trauma, surgery, interventional procedures, or intrathoracic infections. Pneumorrhachis is a rare clinical condition, consisting of intraspinal air. The main causes are iatrogenic, traumatic, and nontraumatic. Spontaneous mediastinum is usually as...

High density lipoprotein - should we raise it?

Low high-density lipoprotein (HDL) cholesterol levels are associated with an increased risk of coronary artery disease and myocardial infarction. Experimental studies have identified several potential anti-atherogenic properties of HDL, including promotion of macrophage cholesterol efflux, endothelial nitric oxide stimulation, anti-inflammatory and anti-thrombotic effects. These observations ha...
