Ulcerative Colitis appearance on colonoscopy Answer - Crypt abscesses and if
toxic megacolon present loss of haustra and blood vessels
A 34-year-old male presents to the primary care office with a complaint of
heartburn that has been present for three months. He has symptoms two to
three times a week, which occurs about 30 minutes after eating. He has tried
over-the-counter antacids and they were helping to relieve his symptoms for a
few months, but they are not working well now. He denies dysphagia,
odynophagia, or weight loss. You decide to treat him with a proton pump
inhibitor at this visit, and he achieves good symptomatic relief with this
therapy. What length of therapy is appropriate in this patient?
A Two to four weeks
B Eight to twelve weeks
C Four to six months
D One year
E Continue indefinitely Answer - If a patient achieves good symptomatic relief
with a course of an empiric, once-daily proton pump inhibitor, therapy may be
discontinued after eight to twelve weeks.
A 63 year-old woman complains of fatigue, loss of appetite, a sore-red tongue,
paresthesias of her feet and hands, and unsteadiness of her gait. Which of the
following tests is be used to confirm the patient's suspected diagnosis?
,A Anti-intrinsic factor antibodies
B Antiparietal cell antibodies
C Coomb's test
D Schilling Test
E Serum folate levels Answer - Anti-intrinsic factor antibodies
A diagnosis of pernicious anemia (PA) can be supported through the presence
of anti-intrinsic factor antibodies.
Antiparietal (B) cell antibodies aren't associated with the development of PA.
The Coomb's test (C) is used in the evaluation of hemolytic anemias. Serum
folate (D) levels are beneficial in evaluating macrocytic anemias, but will not
establish a diagnosis of PA. The Schilling test (D) was once commonly used to
diagnosis PA, but is no longer available due to lack of available radiolabeled
human intrinsic factor.
A 28-year-old man presents for a barium enema; he has a 6-month history of
abdominal cramping, pain, tenesmus, bloody diarrhea, and painful urgency. He
also reports arthralgias, but denies a history of traveling abroad or the use of
antibiotics. On physical exam, he has indurated and painful erythematous
plaques and nodules on both shins. An abdominal exam reveals a mild
tenderness in the lower left quadrant (LLQ). Stool exam is positive for occult
blood and negative for ova and parasites. Lab analysis reveals mild
leukocytosis, microcytic anemia, positive p-ANCA antibodies, and elevated ESR.
What would be the most likely result of a barium enema?
Answer Choices
1 Apple core appearance
2 Cobblestone appearance
3 Lead pipe appearance
4 String sign
5 Thumb printing Answer - lead pipe appearance on barium enema
, Lead pipe colon is the appearance on barium enema of a foreshortened,
narrow colon with loss of redundancy and haustral markings. This sign is
specific for ulcerative colitis (UC), an inflammatory disease of the rectum and
colon. The peak incidence of UC is around 25 to 45 years. P-ANCA antibodies
are associated with UC. Iron deficiency can lead to microcytic anemia. Common
extra intestinal manifestations of UC are erythema nodosum (described as
erythematous plaques and nodules on pretibial areas), arthritis, pyoderma
gangrenosum, uveitis, episcleritis, and sclerosing cholangitis.
Toxic megacolon is a complication of UC characterized by the dilation of the
colon; there is a risk of perforation. There is an increased incidence of colon
cancer (10%) after 10 years of this disease. The inflammation involves the
mucosal tissues only, which are friable and show ulcerations on colonoscopy.
There is also a characteristic continuous involvement and pseudopolyp
appearance caused by mucosal regeneration. Sulfapyridine, mesalamine,
corticosteroids, 6-mercaptopurine, and azathioprine are used for treatment.
Colectomy is curative and is indicated for intractable disease, or in the case of
dysplasia.
An apple core appearance on barium enema is seen in patients with colon
cancer. This sign refers to the shouldered margins of the stricture caused by the
neoplasmic invasion.
A cobblestone appearance and string sign are characteristic for Crohn's disease,
another inflammatory disease of the digestive tract. The cobblestone
appearance refers to the discontinuous areas of inflammation separated by
healthy bowel. String sign, seen in the small bowel series, is the appearance
caused by stricture areas.
Thumb printing is a radiological sign seen in ischemic colitis, a disease most
likely found in elde
