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%.
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.
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.
As appetite fully returns, the child should be eating 200 mL per kilogram of body weight per day. Zinc, potassium, vitamin A, and other vitamins and minerals should be added to both recommended cereal products, or to the oral rehydration solution itself. Children who are breastfed should continue breastfeeding. [22]
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 potencies are available, either as individual components or as specialized formulations.
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 ]
Three variants are known to exist, FAP and attenuated FAP (originally called hereditary flat adenoma syndrome [1]) are caused by APC gene defects on chromosome 5 while autosomal recessive FAP (or MUTYH-associated polyposis) is caused by defects in the MUTYH gene on chromosome 1. Of the three, FAP itself is the most severe and most common ...
There is a risk of development of cancer with fundic gland polyposis, [22] but it varies based on the underlying cause of the polyposis. [4] The risk is highest with congenital polyposis syndromes, and is lowest in acquired causes. [4] [23] As a result, it is recommended that patients with multiple fundic polyps have a colonoscopy to evaluate ...
