Serrated polyposis syndrome (SPS), previously known as hyperplastic polyposis syndrome, is a disorder characterized by the appearance of serrated polyps in the colon. While serrated polyposis syndrome does not cause symptoms, the condition is associated with a higher risk of colorectal cancer (CRC). The lifelong risk of CRC is between 25 and 40%.
The serrated polyposis syndrome (SPS) is a relatively rare condition characterized by multiple and/or large serrated polyps of the colon. Serrated polyps include SSLs, hyperplastic polyps, and traditional serrated adenomas.
MUTYH-associated polyposis (also known as MYH-associated polyposis) is an autosomal recessive polyposis syndrome. [1] The disorder is caused by mutations in both alleles (genetic copies) of the DNA repair gene, MUTYH. The MUTYH gene encodes a base excision repair protein, which corrects oxidative damage to DNA.
Gardner's syndrome (also known as Gardner syndrome, familial polyposis of the colon, [1] or familial colorectal polyposis [2]) is a subtype of familial adenomatous polyposis (FAP). Gardner syndrome is an autosomal dominant form of polyposis characterized by the presence of multiple polyps in the colon together with tumors outside the colon. [ 3 ]
Countries do not always agree on the amounts of vitamins needed to safeguard against deficiency. For example, for vitamin C, the RDAs for women for Japan, the European Union (called Population Reference Intakes) and the US are 100, 95 and 75 mg/day, respectively. [3] [5] [16] India sets its recommendation at 40 mg/day. [17]
Many common brand supplements in the United States contain levels above the DRI/RDA amounts for some vitamins or minerals. Severe vitamin and mineral deficiencies require medical treatment and can be very difficult to treat with common over-the-counter multivitamins. In such situations, special vitamin or mineral forms with much higher ...
Inflammatory cells may be present. Compared with sporadic polyps, polyps that occur in juvenile polyposis syndrome tend to have more of a frond-like (resembling a leaf) growth pattern with fewer stroma, fewer dilated glands and smaller glands with more proliferation. [2]
Low calcium and phosphate may give a clue toward osteomalacia from low vitamin D. [12] Specific vitamins like vitamin D or micronutrient like zinc levels can be checked. Fat soluble vitamins (A, D, E and K) are affected in fat malabsorption. Prolonged prothrombin time can be caused by vitamin K deficiency. [citation needed] Serological studies.
