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: history of present illness: the patient is an 80-year-old gentleman with a history of metastatic pancreatic cancer diagnosed in , status post debulking and gastrojejunostomy surgery as well as radiation and chemotherapy. the patient presents with a 3-day history of dark black stools, lightheadedness, and shortness of breath for one day, and also a 1-day history of mild right upper quadrant pain. the patient has no previous history of melena. he has no chest pain, weakness, numbness, tingling, or dysuria. he has chronic constipation and distention. the patient is on chronic coumadin therapy for a left lower extremity deep venous thrombosis. in the emergency department, the patient was hemodynamically stable. his hematocrit was found to be 25 (down from 34) one month ago. the patient had a nasogastric lavage which was positive for coffee ground material which did not clear with two liters. the patient was transfused one unit of packed red blood cells in the emergency department and admitted to the medical intensive care unit. the patient was also admitted from to for klebsiella bacteremia which was treated with a 10-day course of levofloxacin. past medical history: (past medical history is significant for) 1. pancreatic cancer with known liver metastases treated in with debulking and gastrojejunostomy surgery as well as radiation and chemotherapy. 2. the patient has a history of gastric outlet obstruction secondary to surgery. 3. benign prostatic hypertrophy. 4. sick sinus syndrome; status post pacemaker placement. 5. left lower extremity deep venous thrombosis (on coumadin). 6. melanoma with local excision. 7. recent klebsiella bacteremia; treated with a 10-day course of levofloxacin. past surgical history: (past surgical history is significant for) 1. gastrojejunostomy. 2. gastrojejunostomy tube placement in . allergies: the patient has no known drug allergies. social history: the patient denies tobacco, alcohol, and intravenous drug use. the patient lives with his wife. physical examination on presentation: physical examination on admission revealed his temperature maximum was 99.5, his blood pressure was 100/49, his heart rate was 74, and his oxygen saturation was 96% to 99% on room air. in general, the patient was a well-nourished gentleman in no acute distress. cardiovascular examination revealed a regular rate and rhythm. no murmurs, rubs, or gallops. the lungs were clear to auscultation bilaterally. the abdomen was tympanitic and distended, mildly tender in the right upper quadrant, with no rebound or guarding. extremity examination revealed no clubbing, cyanosis, or edema. neurologic examination was grossly nonfocal. cranial nerves ii through xii were intact. brief summary of hospital course by issue/system: the patient was admitted to the medical intensive care unit. 1. gastrointestinal bleed issues: the patient was transfused multiple units of packed red blood cells and fresh frozen plasma. the patient's coumadin was held. his inr was 2.5 on admission. the patient was given intravenous vitamin k and intravenous protonix q.12h. and was made nothing by mouth. an esophagogastroduodenoscopy done showed reflux from the duodenum/tumor area, but the scope could not be passed into the duodenum secondary to tumor. a nasogastric lavage was repeated which showed coffee-grounds followed by fresh clots of red blood. the patient was sent to interventional radiology for an angioembolization. an angioembolization was done to the gastroduodenal artery on . this procedure was complicated with a right groin hematoma. on , the patient's hematocrit was still slowly dropping. interventional radiology and surgery were consulted again. the patient was sent for a repeat embolization on . this embolization was complicated with a left groin hematoma and pseudoaneurysm. following the second angioembolization, the patient's hematocrit remained stable for 24 hours, and he was transferred to the medicine floor from the unit. the patient received a total of 14 units of packed red blood cells and 10 units of fresh frozen plasma in the unit. on , the patient had a prominent injection into the left femoral pseudoaneurysm. on , the patient had an ultrasound which showed a pseudoaneurysm still present in the left femoral area with flow through it. his hematocrit was stable at that time. on , the day following the patient being transferred to the floor, his hematocrit was dropping slowly to 28 with an expanding left femoral hematoma. the patient received 2 units of packed red blood cells, and 2 units of fresh frozen plasma, and 1 mg of intravenous vitamin k. vascular surgery was consulted again, and the patient was to go for repair of the left femoral pseudoaneurysm. the patient's hematocrit was stable for the next three days at approximately 32. his inr was corrected to 1.3. on , the patient was taken to the operating room for pseudoaneurysm repair. on , the patient was found to still have a slowly dropping hematocrit once again. he was transfused one unit of packed red blood cells. a repeat esophagogastroduodenoscopy was done on which was negative. the patient's hematocrit remained stable at approximately 30 until discharge. 2. cardiovascular issues: the patient was ventricularly paced, and therefore ischemia was unable to be evaluated based on his electrocardiogram in the emergency department. the patient ruled out for a myocardial infarction, and his antihypertensive medications were held. the patient's blood pressure remained stable throughout his hospitalization. 3. gastrointestinal issues: the patient has a history of chronic constipation. the patient was placed on a bowel regimen which included senna and docusate. the patient was also placed on simethicone for complaints of bloating. the patient had regular bowel movements after being transferred to the floor and did not have any further gastrointestinal complaints. the patient was also started on viokase with meals for possible pancreatic dysfunction. 4. coagulopathy issues: the patient was initially admitted on coumadin with an inr of 2.5 following reversal of anticoagulation with fresh frozen plasma and vitamin k while the patient was in the medical intensive care unit. once the patient was transferred to the floor, his inr continued to increase to a maximum level of 2.9. the patient again received 2 more units of fresh frozen plasma and 1 mg of intravenous vitamin k while on the floor and then placed on oral vitamin k to maintain his inr at less than 1.5. the patient was discharged with an inr of 1.3 which remained stable following the initial reversal with fresh frozen plasma and vitamin k. 5. pseudoaneurysm issues: the patient's angioembolization procedures were complicated with bilateral groin hematomas and a left groin pseudoaneurysm. the patient had bilateral ultrasounds initially done showing no pseudoaneurysm on the right, just a hematoma, and a pseudoaneurysm on the left. the patient had a thrombin injection performed and a repeat ultrasound which showed the pseudoaneurysm was still present that then began to expand with an expanding hematoma and a drop in his hematocrit. the patient went for repair of the pseudoaneurysm on with no further complications. condition at discharge: condition on discharge was good. discharge status: discharge status was to home. discharge diagnoses: 1. metastatic pancreatic cancer. 2. gastrointestinal bleed. 3. left femoral pseudoaneurysm. discharge instructions/followup: 1. the patient was instructed to follow up with dr. in one week. 2. the patient was instructed to follow up with dr. in 10 to 14 days. medications on discharge: (discharge medications included) 1. clonazepam 0.5 mg by mouth at bedtime. 2. doxazosin 2 mg two tablets by mouth at bedtime. 3. pantoprazole 40 mg by mouth q.12h. 4. viokase two tablets by mouth three times per day (with meals). , m.d. dictated by: medquist36 procedure: other endoscopy of small intestine other endoscopy of small intestine injection or infusion of thrombolytic agent other incision with
