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: past medical history: 1. peripheral vascular disease status right below knee amputation, status post aortobifemoral bypass graft, status post right femoral popliteal bypass graft. 2. history of peptic ulcer disease. 3. gastroesophageal reflux disease. 4. history of pericarditis. 5. history of mesenteric ischemia, status post right hemicolectomy and small bowel resection, hypercoagulable state. allergies: the patient has no known drug allergies. medications on admission: 1. aspirin, which was discontinued. 2. lovenox, had been discontinued. social history: the patient is on disability. he has not had alcohol for the last 17 years. he does smoke one pack per day of cigarettes. he lives alone. physical examination: examination revealed the blood pressure of 122/86, pulse rate 119, respirations 20, 94% oxygen saturation on room air. the patient was sleeping easily and comfortable in no acute distress. he felt lightheaded. heent: unremarkable. cardiac: regular rate and rhythm with tachycardia. chest was clear to auscultation bilaterally. abdomen: soft, nontender, nondistended with normal bowel sounds. rectal: examination was guaiac negative. laboratory data: labs obtained included the following: cbc, 13.9. hematocrit 36.8, platelet count 260,000, inr 1.1, bun 28, creatinine 1.5, potassium 5.4, differential on the white count was normal. repeat hematocrit two hours later was 31, felt secondary to hemodilution post two liters normal saline. hospital course: the patient was admitted to the medical service. he was made npo. gastroenterology was requested to see the patient. he underwent an upper endoscopy, which showed a graft erosion through the duodenal wall with esophagus. biopsy was obtained. pathology results are pending. the patient was begun on empiric antibiotic therapy of ampicillin 2 grams q.6h.; ceftizoxime 1 gram q.24; flagyl 500 mg q.8h. general surgery was consulted and vascular surgery was consulted. the patient complained of left first toe pain and ischemic changes. he underwent, on exploratory laparotomy with removal of the tex graft and duodenotomy closure with a jejunostomy and duodenostomy. he received one unit of packed cells. fluconazole was begun on for uti. he was transferred to the sicu on . tube feeds were begun and the department of nutrition was consulted for appropriate nutritional management. the patient was begun on impact with fiber, goal-infusion rate 80 cc per hour. on , the patient complained of abdominal pain. cbc, chem 7 and lfts were obtained, which were normal. the tube feeds were held with improvement in her symptoms. he was begun on tpn. tube feeds were restarted over the next 48 hours. the patient required picc line placement for long-term antibiotics. on , the ng tube was clamped and then discontinued. on , the patient had nausea, vomiting, and had emesis of 500 cc and the ng tube was replaced. the patient, at that time, had a temperature maximum of 101.6. blood and urine cultures were obtained. the cbc revealed normal white count. ct of the abdomen was obtained on and there was no intra-abdominal fluid collection. on , the ng tube was clamped again. residuals were checked. the patient had an episode of emesis and the ng tube was placed to suction. tube feeds were changed at this time to promod with fiber. he received a second unit of packed cells on . he underwent an upper gi with small-bowel follow through on . there was still some ileus, which remained. he was continued on his suction. hematology/oncology consultation was placed regarding the history of hypercoagulability. recommendations were that he probably has hemosiderins and antiphospholipid antibodies. anticoagulation should be continued. the hemosiderin should be treated with vitamin b 12, b complex and folate. the patient should followup with the hematology clinic upon discharge for long-term monitoring. their number is . on the ng tube was clamped again. there were no residuals. he was placed to drainage. on because of persistent ischemic left toe pain and progressive ischemic changes of the toe and the foot, he underwent an arteriogram, which demonstrated occluded infrarenal aorta, occluded celiac sma and a bf graft. there was a distal flow in the foot on the affected side. he underwent ultrasound of the upper extremities to determine patency of the subclavian arteries and axillary veins and arteries. they were patent. on he underwent a left axillary to left common femoral artery bypass graft with ptfe and a left femoral to ak popliteal with ptfe. ultrasound was done at the bedside. the graft was patent. the patient remained hemodynamically stable. he was transferred from the pacu to the vicu for continued monitoring and care. the patient was transferred out of the vicu on to regular nursing floor. the nasogastric tube was removed on and he was again on clear sips, which he tolerated. on , regular diet was begun. po intake would be monitored. tube feeds will be continued until the p.o. intake was adequate. department of physical therapy was requested to see the patient regarding independence of his mobility and home safety. physical examination: wounds were clean, dry, and intact. left first toe remained improved with circulation, but still dusky and discoloration was noted. stool for c. difficile was sent prior to discharge. this was pending at the time of dictation. medications on discharge: 1. roxicet 1 to 2 tsp q.4 to 6h.p.r.n.for pain. 2. folate 1 mg q.d. 3. thiamine 100 mg q.d. 4. flagyl 500 mg q.8h. 5. levofloxacin 500 mg q.d. 6. fluconazole 200 mg q.d. 7. percocet 30 mg q.d. 8. lopressor 25 mg b.i.d. hold for systolic blood pressure less than 110, heart rate less than 55. 9. multivitamin tablet with b complex q.d. 10. reglan 10 mg a.c. and h.s. addendum: regarding tube feeds and follow-up evaluations will be made in an addendum discharge on the day of discharge. discharge diagnoses: 1. upper gi bleed secondary to graft erosion of the duodenum, status post exploratory laparotomy with removal of tex graft with a duodenotomy with closure and a jejunostomy and duodenostomy. 2. postoperative ileus resolved. 3. blood-loss anemia transfused, corrected. 4. history of hypercoagulable state, treated with lovenox 100 b.i.d. 5. ischemic left toe status post angioplasty, status post left axillofemoral with ptfe and left femoral ak popliteal with ptfe. , m.d. dictated by: medquist36 procedure: parenteral infusion of concentrated nutritional substances other enterostomy other
