-Barium is a silver-white metallic compound that outlines the colon and rectum on an x-ray and helps show abnormalities.
-Air is also put into the rectum and colon to further enhance the x-ray.
-Double contrast barium meal is done by giving effervescent tablets along with barium.

An example of Double-contrast barium enema.
-In barium swallow a thick solution of barium sulphate is given to the patient for swallowing.
-This is mainly done for the study of esophagus and pharynx
-In barium meal a dilute solution of barium sulphate is used (about 500 ml is given orally).
-Barium meal examinations are used to study the lower esophagus, stomach and duodenum.
-Barium follow through examinations are used to study the small intestine.

🔻Radiation of pain:
-It is the extension of the pain to another site while the initial pain persists.
-Radiating pain is of same character of original site.
-For example, penetration of duodenal ulcer posteriorly causes pain both in epigastrium and back.
-Pain of pancreatitis radiates to back.

🔻Referred pain:
-It is pain that is felt at a distance from its source. It's not felt at the site of the disease.
-For example, inflammation of the diaphragm causes a pain experienced only at the tip of the shoulder.
-Hip joint pathology may cause referred pain in knee joint.
-Referred pain in the epigastrium from the heart; referred pain in the abdomen from pleura; referred pain over the testis from the ureter..etc
-Referred pain is caused by the inability of the central nervous system to distinguish between visceral and somatic sensory impulses.

🔻Shifting/migration of pain:
-Origin of pain is in one site; later pain shifts to another site and pain at original site disappears.
-Pain when begins in viscera, is felt at the same somatic segmental area in the body; but once parietal layer is involved by inflammation/ pathology pain is felt at the anatomical site.
-Common example is that of acute appendicitis.
