Tuberculosis (TB) is a potentially serious infectious disease that mainly affects your lungs. The bacteria that cause tuberculosis are spread from one person to another through tiny droplets released into the air via coughs and sneezes. Once rare in developed countries, tuberculosis infections began increasing in 1985, partly because of the emergence of HIV, the virus that causes AIDS.
Upper Endoscopy (EGD) What is Upper Endoscopy (EGD)? An esophago-gastro-duodenoscopy (EGD) is a procedure that allows your physician to examine the lining of the upper part of your gastrointestinal tract, including the esophagus, stomach and the duodenum (the beginning part of your small intestines).
There are two basic types of endoscopy: 1  Upper endoscopy â The esophagus, stomach, and small intestines can be viewed by a thin flexible tube inserted through the mouth. 2  Colonoscopy â The lining of the large intestine, colon and rectum can be viewed by a flexible tube inserted through the rectum.
