THE TEST OF LACTOSE

Lactose intolerance is one of the most common gastrointestinal disorder. This clinical situation is from deficiency of the enzyme lactase in the intestine, either by genetics or temporary alteration of the small intestine. Without adequate levels of this enzyme, the digestive system can not absorb lactose, which is the main ingredient in milk and milk products. When this happens, the unabsorbed lactose is fermented by colon bacteria causing release of gas.
For detecting this particular clinical condition we do the examination of lactose breath test. This test is a simple, safe, reliable, non-invasive examination. It is very important to make that assessment, because the correct diagnosis can help in implementing an effective treatment against dyspepsia and malabsorption of lactose and thus eliminate chronic and persistent symptoms.

Carcinoid Tumour Case Study

Apr 15, 2013

Carcinoid tumours originate in the cells of the neuroendocrine system. They have been classified according to their embryologic site of origin, such that foregut carcinoids start in the lungs, bronchi or stomach; midgut carcinoids start in the small intestine, appendix, or proximal large bowel; and hindgut carcinoid tumors start in the distal colon or rectum. The appendix presents the most frequent site of carcinoid tumours followed by the rectum, ileum, lungs, bronchi, and stomach. These neoplasms characteristically present in patients 50 to 60 years of age.
