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 past medical history significant for coronary artery disease (status post coronary artery bypass graft), diverticulosis, and prostate cancer (status post radiation therapy) who presented with hospital complaining of some bright red blood per rectum. on the evening prior to admission, the patient was noted to have approximately 600 cc of bright red blood in his diaper. he was then transferred to the emergency department for further evaluation. the patient denied any abdominal pain, dizziness, chest pain, shortness of breath, or other complaints. he denied any previous occurrence of rectal bleeding. review of systems: the patient complained of a mild headache which he has had for several weeks. past medical history: 1. coronary artery disease; status post coronary artery bypass graft. 2. hypertension. 3. gout. 4. prostate cancer. 5. status post brachy therapy. 6. diverticulosis. 7. diverticulitis. 8. methicillin-resistant staphylococcus aureus. 9. percutaneous endoscopic gastrostomy tube placement. medications on admission: 1. levaquin 250 mg by mouth once per day. 2. prednisone 60 mg by mouth once per day. 3. captopril 6.25 mg by mouth three times per day. 4. protonix 40 mg by mouth once per day. 5. lopressor 25 mg by mouth twice per day. 6. aspirin. 7. colace. 8. multivitamin one tablet by mouth once per day. allergies: no known drug allergies. social history: the patient is a resident at . he has a legal guardian who is a neighbor. denies any current use of alcohol or tobacco. physical examination on presentation: physical examination revealed vital signs which included a temperature of 97.1 degrees fahrenheit, his heart rate was 86, his blood pressure was 140/72, his respiratory rate was 18, and his oxygen saturation was 99% on 2 liters. in general, the patient was a cachectic-appearing gentleman in no acute distress. head, eyes, ears, nose, and throat examination revealed normocephalic and atraumatic. extraocular movements were intact. the sclerae were anicteric. the neck was supple. no jugular venous distention. the lungs were clear to auscultation bilaterally. cardiovascular examination revealed tachycardia. a regular rhythm. normal first heart sounds and second heart sounds. no murmurs, rubs, or gallops. the abdominal examination revealed positive bowel sounds. the abdomen was soft, nontender, and nondistended. extremity examination revealed the extremities were warm and dry. no edema. there was a pressure sore on the right heel. neurologic examination revealed the patient was alert and oriented times three. no focal deficits. concise summary of hospital course by issue/system: 1. gastrointestinal bleed issues: the patient was admitted with complaints of rectal bleeding with a blood loss of approximately 600 cc. in the emergency department, he had another episode of rectal bleeding of approximately 100 cc. the patient received a total of 5 units of packed red blood cells to maintain his hematocrit levels of greater than 30. he was evaluated by gastroenterology. he had an upper endoscopy which was significant only for mild gastritis. he then had a colonoscopy which showed a fungating rectal mass thought to be the etiology of his bleeding. his hematocrit remained stable, and he did not have any further active bleeding. the surgical service also evaluated the patient and felt that the bleeding component of his rectal mass was consistent with radiation prostatitis. they recommended followup with gastroenterology for argon laser treatment should the bleeding recur. 2. rectal mass issues: the patient was found to have a fungating rectal mass on colonoscopy. there was concern for recurrence of his prostate cancer (although his prostate-specific antigen was normal) versus a rectal carcinoma primary. pathology of the mass was sent; however, it was not diagnostic showing cellular atypia consistent with radiation damage. the patient had a transrectal ultrasound which showed evidence of recurrent prostate cancer with invasion into the right anterior wall of the rectum. the patient was referred to dr. in oncology for further evaluation and was given an appointment for the week following discharge. 3. congestive heart failure issues: congestive heart failure with an ejection fraction of 20%. the patient's cardiac medications were initially held upon admission given his gastrointestinal bleeding and concern for hypotension. the patient had an episode of flash pulmonary edema which did respond well to lasix, nitroglycerin, and hydralazine. the patient was then restarted on his beta blocker and ace inhibitor in addition to intravenous lasix. his symptoms improved with this regimen. he was then stabilized on the beta blocker and ace inhibitor and was taken off the lasix. the plan was to monitor him as an outpatient, and should he begin to develop symptoms of fluid overload, he should be restarted on his daily dose of lasix. 4. chronic renal insufficiency issues: the patient with baseline renal insufficiency with a baseline creatinine ranging from 1.4 to 1.5. his creatinine on admission was 1.4. with diuresis his creatinine did initially trend up and then normalized to his bowel sound value without any further intervention. 5. gastrointestinal issues: the patient with a history of multiple failed swallowing studies. he had a percutaneous endoscopic gastrostomy tube placed and had been nothing by mouth for approximately four months. the patient was re-evaluated with a speech and swallow study and did pass the video swallow study. at this point, he was restarted on a diet of pureed foods and thick liquids. he was also continued on his tube feeds; although the rate was lowered to 30 cc per hour to maintain adequate nutrition. 6. fluids/electrolytes/nutrition issues: the patient was maintained on tube feeds with by mouth supplementation as above. he was encouraged to consume boost shakes. his electrolytes were followed and repleted as needed throughout his hospitalization. 7. urinary tract infection issues: the patient's urine grew out klebsiella of two morphologies which were sensitive to multiple cephalosporins. the patient had initially been on levaquin and flagyl and was then transitioned over to a by mouth cephalosporin when the sensitivities came back. his leukocytosis resolved with antibiotic therapy. on antibiotics for a total of seven days of treatment for this complicated urinary tract infection. 8. right heel ulcer issues: the patient with a chronic pressure sore on his right heel. the patient was evaluated by the plastic service who recommended bacitracin ointment to keep the wound moist and keeping the wound open. he also was prescribed a pressure boot which was to be kept on his right foot at all times to minimize the risk of pressure to the ulcer. they did not recommend any further intervention at this time. 9. prophylaxis issues: the patient was maintained on a proton pump inhibitor for gastrointestinal prophylaxis and pneumatic compression boots for deep venous thrombosis prophylaxis throughout his hospitalization. 10. code status issues: the patient was full code. his legal guardian did consent him for all procedures. 11. headache issues: the patient was admitted with a history of headaches. he had been evaluated as an outpatient by rheumatology for a question of temporal arteritis. his temporal artery biopsy did come back negative. he had been empirically started on prednisone, but given the negative biopsy, he was then tapered off the prednisone. his prednisone taper was to continue following discharge. his headache were well controlled with tylenol during his hospitalization and were thought to be tension related. condition at discharge: condition on discharge was stable. discharge status: discharge status was to nursing home. discharge diagnoses: 1. gastrointestinal bleed. 2. rectal mass. 3. history of prostate cancer. 4. prostatitis; status post radiation therapy. 5. mild gastritis. 6. congestive heart failure. 7. impaired swallowing function. medications on discharge: (discharge medications included) 1. multivitamin liquid 5 ml by mouth once per day. 2. lansoprazole extended-release liquid 30 mg by mouth every day. 3. bacitracin ointment applied to right heel twice per day. 4. tylenol elixir 650 mg by mouth q.4-6h. as needed. 5. percocet elixir 5 ml to 10 ml by mouth q.4-6h. (please give prior to physical therapy). 6. cefpodoxime 200 mg by mouth q.12h. (times seven days). 7. metoprolol 25 mg by mouth three times per day. 8. lisinopril 5 mg by mouth once per day. 9. ativan 0.5 mg by mouth q.4h. as needed (for anxiety). 10. prednisone taper 20 mg by mouth once per day times four days; then 10 mg by mouth once per day times four days; then 5 mg by mouth once per day times four days; then stop. discharge instructions/followup: 1. the patient was instructed to follow up his primary care physician in one to two weeks. 2. the patient was instructed to follow up with dr. in oncology; appointment on at 10 a.m. the patient was call prior to scheduled appointment to confirm. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified other endoscopy of small intestine enteral infusion of concentrated nutritional substances closed [endoscopic] biopsy of large intestine diagnoses: urinary tract infection, site not specified congestive heart failure, unspecified unspecified essential hypertension malignant neoplasm of prostate unspecified disorder of kidney and ureter hemorrhage of gastrointestinal tract, unspecified unspecified gastritis and gastroduodenitis, without mention of hemorrhage other specified inflammatory diseases of prostate
