Write answer in between .Q:A 33-year-old man has a history of intermittent bloody diarrhea, tenesmus, fever, fatigue, and lower abdominal cramps for the past 2 weeks. On physical examination, he is lethargic and appears lean and pale. He has aphthous stomatitis, red congested conjunctiva, and tender swollen joints. At the doctors office, his pulse is 114min, blood pressure is 10276 mm Hg, respirations are 20min, and his temperature is 39.4C 102.9F. There is vague lower abdominal tenderness and frank blood on rectal examination. Laboratory studies show:Hemoglobin 7.6 gdLHematocrit 33Total leucocyte count 22,000mm3Stool assay for C.difficile is negativeAbdominal X-ray shows no significant abnormalityHe is symptomatically managed and referred to a gastroenterologist, who suggests a colonoscopy and contrast barium study for the diagnosis. Which of the following is the most likely combination of findings in his colonoscopy and barium study?? A: Colonoscopy: Multiple vascular malformations that resemble telangiectasias on the colon wall, Barium study: Normal, B: Colonoscopy: Continuous ulcerated lesions involving the mucosa and submucosa granular mucosa, crypt abscess, and pseudopolyps, Barium study: Lead pipe colon appearance, C: Colonoscopy: Patches of mucosal erosions with pseudomembrane formation, Barium study: Lead pipe colon appearance, D: Colonoscopy: Discontinuous transmural skip lesions with aphthoid linear ulcers and transverse fissures, non-caseating granulomas, and strictures, Barium study: Cobblestone appearance with strictures, E: Colonoscopy: Patches of mucosal erosions with pseudomembrane formation, Barium study: Cobblestone appearance with strictures,  <response>: Based on the description of intermittent bloody diarrhea, abdominal cramps, fever, fatigue, and the physical exam findings of conjunctivitis, oral ulcers, swollen joints, anemia, and leukocytosis, this patient likely has inflammatory bowel disease, specifically ulcerative colitis. The colonoscopy and barium study are being done to confirm the diagnosis and evaluate the extent of disease. Choice A describes vascular malformations which would not match the clinical presentation. Choice B describes continuous ulcerated lesions, granular mucosa, crypt abscess and pseudopolyps which are classic colonoscopic findings in ulcerative colitis. The lead pipe appearance on barium study also matches ulcerative colitis.Choice C describes pseudomembranes more typical of C. difficile infection which was ruled out. Choice D describes discontinuous lesions, non-caseating granulomas, and strictures more typical of Crohns disease rather than ulcerative colitis. The cobblestone appearance also matches Crohns.Choice E has mixed findings - pseudomembranes do not match ulcerative colitis, while the cobblestone appearance matches Crohns disease.Therefore, choice B with continuous colonic involvement, pseudopolyps, and lead pipe appearance on barium study is most consistent with ulcerative colitis.B: Colonoscopy: Continuous ulcerated lesions involving the mucosa and submucosa granular mucosa, crypt abscess, and pseudopolyps, Barium study: Lead pipe colon appearance
