[Q]: Question: A colonoscopy of colorectal cancer screening is performed on a patient with ulcerative colitis with involvement up to the transverse colon. Colonoscopy shows no signs of inflammatory activity. Multiple biopsies were performed every 10 cm. The biopsies were reviewed by 2 expert pathologists demonstrating a focus of high grade dysplasia in one of the biopsies performed in the sigmoid colon. What would you indicate next? 
 Options:  <1> Repeat the colonoscopy to confirm the diagnosis. <2> Intensive surveillance with colonoscopy every 3 to 6 months. <3> Repeat the examination and perform a chromoendoscopy to identify the lesion and perform an endoscopic mucosectomy. <4> Total proctocolectomy. <5> Treatment with mesalazine at doses of 2-3 grams per day and repeat the scan at 3 to 6 months.

[Q]: Question: In the treatment of heart failure: 
 Options:  <1> Angiotensin receptor blockers (ARA II) have shown superiority over angiotensin-converting enzyme (ACE) inhibitors and should be the first therapeutic option. <2> Aldosterone antagonists have not shown prognostic improvement, being contraindicated in patients with advanced systolic dysfunction and functional grade IV. <3> Beta-blockers have been shown to decrease mortality in patients with decreased ejection fraction. <4> Cardiac resynchronization pacemaker therapy is indicated in patients with systolic dysfunction whenever the QRS is narrow (less than 120 msg). <5> The implantation of automatic defibrillators is contraindicated in patients with ventricular dysfunction, especially if it is caused by ischemia.
