Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: rectal bleeding prostate biopsy. major surgical or invasive procedure: colonoscopy. tagged rbc scan. history of present illness: 79 yo aam w/pmh sx for cad s/p cabgx2 and pci, ventricular pacer, dm2, and bph s/p recent biopsy for elevated psa who was at home sitting at his computer when he felt the urge to defecate. he notes that he delayed going to the bathroom for a while, then noted increasing urgency to move his bowels, and on the way to the bathroom, he passed a large amount of bright red blood per rectum, with associated lighthesadness. no sob, chest pain, nausea or vomiting, or sob. at the time, he called ems and was transported to the ed, where he continued to pass multiple clots of brb. he was transferred emergently to the micu for stabilization. past medical history: cad s/p cabg x 2 and pci, pacer dm-2 on insulin pvd. bph chronic anemia chronic thrombocytopenia prostate cancer - diagnosed today - had biopsy one week ago today, but did not have any bleeding afterwards at that time. social history: retired biochemistry professor. quit tobacco in occasional etoh - one glass of wine per day. lives at home with his wife. children in the area. family history: dm-2 physical exam: tm 98.8 bp 140/57 hr 64 o2 sat: 93% 2l gen: well appearing. alert and oriented. hard of hearing. conversing comfortably. heent: perrl. eomi. mmm. jvd to 12 cm. lungs: inspiratory bibasilar crackles. poor inspiratory effort. no rales or rhonchi. hrt: irreg irreg. no mrg. abd: s/nt. mildly distended. +bs. fem art sheath in place. no bleeding or tenderness at site. ext: 2+ pitting edema in ble. 2+carotid, radial, dp pulses. purplish discoloration of ble. no rash or tenderness. neuro: 5/5 mm strength bilaterally. intention tremor. negative ftn. pertinent results: hct 27.7 --> 33.8 cex3 negative. pt: 13.5 ptt: 27.1 inr: 1.2 137 101 65 / 246 agap=16 -------------

interpretation: following intravenous injection of autologous red blood cells label with technetium-m, blood flow and delayed images of the abdomen were obtained for 90 minutes. blood-flow images do not show any abnormal trace of activity. delayed blood-flow images show increased trace of activity in the area behind the urinary bladder. this area is somewhat obscured by the activity in the urinary bladder and the penile contamination. increased trace of activity is also seen in the sheets adjacent to the patient's buttock, who was having bright red blood per rectum during the time of this study. impression: findings are consistent with active bleeding in the rectosigmoid area. ir embolization: no active extravasation of contrast. no evidence of angiodysplasia, arteriovenous malformation or aneurysm involving the bowel vascular tree. no finding is present for which intervention could be directed. local anesthesia in the right inguinal region with 5 cc of 1% lidocaine. a total of 44 cc of optiray radiograph contrast was utilized. no immediate complications. impression: no angiographic finding that could warrant intervention. follow-up with endoscopy may be of use, if indicated. on discussion with the intensive care unit the right common femoral 5-french vascular sheath was left in situ postprocedure. all other equipment was removed. the sheath was fixed in place with a single 0 silk suture and a tegaderm dressing. sigmoidoscopy: a single diverticulum was seen in the splenic, however, the presence of more diverticula can not be excluded due to the poor prep. colonoscopy: impression: 1. an adherent clot at 8 cm from the anal verge and localized to the left lobe of prostate gland by simultaneous palpation and endoscopy. source of gi bleeding is due to post-prostate biopsy bleed. two endoclips placed for hemostasis. 2. angioectasia in the mid-ascending colon 3. polyp in the sigmoid colon 4. diverticulosis of the sigmoid colon brief hospital course: impression: 79 year old man with hx cad and mi s/p ptca on plavix and asa, ventricular pacer, dm2, and prostate cancer presents with brbpr prostate biopsy performed several days prior. 1. brbpr: on admission to the micu, patient was initially stable, and in the early morning, he became tachycardic, and dropped his blood pressure into the 60s/30s, and received 4u prbcs and 2l ns for resuscitation. on evaluation by gi, patient was felt to need a tagged rbc scan by ir, which showed bleeding at the rectal sigmoid junction, with continued brbpr. an embolization was attempted in ir, but it was felt that they were unable to localize the bleeding and the embolization was unsuccessful. a femoral sheath was left in place at the time. a sigmoidoscopy was attempted as well, but also did not localize site of bleeding due to incomplete bowel prep. patient was then prepped for colonscopy in am to attempt to further localize the site of bleeding. colonoscopy was performed, and showed an adherent clot at left lobe of the prostate gland, with endoclips applied for hemostatis, as well as angioectasia, polyps, and diverticuli. it was felt that the source of gi bleeding was due to post-prostate biopsy bleeding. after hemostasis was achieved during colonoscopy, patient remained stable with no further decrease in hematocrit. his platelet count decreased to 75 throughout admission; a hit panel was sent and pending at the time of discharge. patient was placed on iv protonix, and his plavix and aspirin were held. two large bore peripheral ivs were placed, and patient was transitioned to po protonix. patient's hematocrit was monitored closely. on admission, hematocrit was originally 27.7, which dropped to 23, and after transfusion of 7u prbc, his hematocrit stabilized at 35. on discharge, his hematocrit was he had trace ob+ stools on discharge, felt to be residual from his large volume lgib two days prior. 2. cad. patient had three sets of negative cardiac enzymes and no changes on ekg, as well as no complaints of chest pain. he was restarted on his blood pressure medications when he was transferred out of the micu; however, he had an asymptomatic hypotensive episode of sbp in the 90s, and patient's lisinopril and imdur were both discontinued, and he was discharged only on metoprolol 50 mg po qd. he was also restarted on his atorvastatin 10 mg po qd. 3. dm2, on insulin. patient was placed on a diabetic diet, with fsqid and ssi per his sliding scale with nph 18 qam and 17 qpm. 4. prostate cancer. patient's prostate cancer was diagnosed on the day of the prostate biopsy. stage is unknown. 5. fen. his electrolytes were stable throughout admission. he was able to take full diet. his i/os and daily weights were monitored. 6. rehabilitation. patient was seen by physical therapy during his admission. 7. access - patient had two large-bore peripheral iv's placed. 8. code - dnr/dni. 9. disposition - patient was discharged to home. medications on admission: isosorbide lasix flomax toprol lipitor plavix discharge medications: 1. tamsulosin 0.4 mg capsule, sust. release 24hr sig: two (2) capsule, sust. release 24hr po hs (at bedtime). 2. atorvastatin calcium 10 mg tablet sig: one (1) tablet po daily (daily). 3. furosemide 20 mg tablet sig: two (2) tablet po daily (daily): take 40 mg 5 days a week and 20 mg 2 days per week. 4. insulin 70/30 70-30 unit/ml suspension sig: 18 u qam, 17 u qpm as directed subcutaneous twice a day. discharge disposition: home discharge diagnosis: rectal bleed discharge condition: good discharge instructions: please do not take your aspirin, plavix, toprol, lisinopril and isosorbide until you follow up with dr. in the clinic. return to the ed or call your doctor if you have any episodes of rectal bleeding, lightheadedness, dizziness, shortness of breath, chest pain or if your symptoms worsen. followup instructions: follow up with dr. or one of his colleagues at the clinic in 1 week. call to make an appointment. he will take your blood pressure and talk to you about restarting your blood pressure medications as well as your aspirin and plavix. md procedure: colonoscopy
