1 Felon: This bacterial infection of the finger pad, caused by the same organisms that cause paronychia, is usually the result of a puncture wound. 2  The wound allows the introduction of bacteria deep into the fingertip pad. 3  Because the fingertip has multiple compartments, the infection is contained in this area.
The interlobular septae are located between secondary pulmonary lobules and are continuous with both the subpleural interstitium (peripheral connective tissue) and the peribronchovascular interstitium (axial connective tissue) as well as the more delicate intralobular septa.he interlobular septa are incomplete allowing for communication between adjacent secondary pulmonary lobules (canals of Lambert and pores of Kohn).
Vertebral artery dissection is a flap-like tear of the inner lining of the vertebral artery, which is located in the neck and supplies blood to the brain. After the tear, blood enters the arterial wall and forms a blood clot, thickening the artery wall and often impeding blood flow. The symptoms of vertebral artery dissection include head and neck pain and intermittent or permanent stroke symptoms such as difficulty speaking, impaired coordination and visual loss. It is usually diagnosed with a contrast-enhanced CT or MRI scan.
