Which of the following statements regarding diverticulosis of the colon is INCORRECT

A. Bruton's disorder: Also known as X-linked agammaglobulinemia, this is a primary immunodeficiency that results in absent or reduced B cells and recurrent bacterial infections. It does not involve distinct facial features or limb defects as described in the question.

B. SCID: Severe Combined Immunodeficiency involves profound defects in both B and T lymphocyte function, leading to severe infections early in life. It is not associated with the described craniofacial abnormalities or limb deformities.

C. Potter syndrome: This condition is caused by severe oligohydramnios, often due to bilateral renal agenesis, and leads to characteristic physical features including widely spaced eyes with epicanthic folds, low-set ears, a broad or beaked nose, a receding chin, and limb deformities.

D. Down Syndrome: While individuals with Down Syndrome often have characteristic facial features such as upslanting palpebral fissures, flat nasal bridges, and low-set ears, they typically do not have beak-like noses, receding chins, or limb defects in the way described.

A. Low-residue diet predisposes to colon diverticula: A low-fiber (low-residue) diet leads to harder stools and increased intraluminal pressure during bowel movements, which promotes the formation of diverticula, especially in the sigmoid colon.

B. Diverticulum may become infected, causing diverticulitis: When fecal material becomes trapped in a diverticulum, it can lead to localized infection and inflammation known as diverticulitis, which may cause pain, fever, or even abscess formation.

C. Ulceration of lining of diverticula caused by fecal material in the diverticula may cause bleeding from the ulcerated diverticulum: Trapped fecal matter can irritate and ulcerate the mucosal lining of diverticula, leading to localized bleeding, which may be seen as rectal bleeding or blood in the stool.

D. Diverticula predispose to colon carcinoma: Diverticulosis is not considered a premalignant condition. Although both conditions may coexist in older adults, the presence of diverticula does not increase the risk of colon cancer.
