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 a 75-year-old gentleman with a history of hypertension, peptic ulcer disease, and mental retardation, who was admitted from an outside hospital on with bright red blood per rectum, hypotension and an hematocrit of 34. his hematocrit then decreased to 23 and the patient was transfused. at that time the patient refused surgery or any other gi procedure to evaluate the source of the bleed. the patient had a rebleed and was transported to . while at the he was transported to the medical intensive care unit. at that time an angiogram was performed that was negative. additionally, on the patient rebled. a bleeding scan was performed that revealed a jejunal source. the patient was then embolized at this source by interventional radiology. throughout the stay the patient was intubated. on the patient was extubated. on his hematocrit dropped from 35 to 28. a bleeding scan was performed that was negative. during this time the patient was also started on broad-spectrum antibiotics including vancomycin, ceftazidime and flagyl. on a ct was performed that revealed a dvt in the left femoral vein. on an inferior vena cava filter was placed. on a transesophageal echocardiogram was done that was negative. on the patient had a gout flare. on his hematocrit was stable. antibiotics were discontinued, and it was felt that the patient's fevers were secondary to his dvt. on the patient was stable and so on he was transferred to the medicine service. physical examination: at that time his temperature was 98.5, blood pressure 134/67, heart rate 82, respiratory rate 20, saturating at 96% on four liters of oxygen. he was in no acute distress. heart was regular rate and rhythm. lungs had mild rhonchi, no wheezes or decreased breath sounds. abdomen was soft, nontender, nondistended. extremity examination showed that left lower edema was noted. laboratory data: his laboratory studies at the time of transfer to the medicine service were white count 10.2, hematocrit 32.4, platelet count 444. basic metabolic profile was as follows: sodium 142, potassium 3.8, chloride 102, bicarbonate 32, bun 28, creatinine 0.7 and glucose 106. his inr was 2.1. hospital course: during his stay on the medicine service, the hospital course was as follows: 1. gi: the patient's hematocrit remained stable in the 30-32 range. the patient continued to have guaiac positive stools however. no need ever arose for a transfusion. 2. respiratory: the patient was brought in on four liters of oxygen. by the end of his stay he was stable on room air. he received atrovent nebulizers p.r.n. he also received chest physiotherapy as well as respiratory therapy. the patient has a very poor cough mechanism and was therefore unable to mobilize his pulmonary secretions. 3. dvt: during his stay a right upper extremity dvt was also documented when the patient developed upper extremity swelling. no anticoagulation was started due to the fact that the patient was continuing to have guaiac positive stools and had a recent history of a gi bleed. 4. nutrition: during his stay on the general medicine service the patient had a video swallowing study which revealed that he aspirated thin liquids, thus he was started on a pureed and nectar diet and tolerated this well. 5. hypertension: the patient was initially on atenolol 60 q. day and amlodipine. his amlodipine was discontinued due to the fact that it can have cytotoxic effects. the patient was maintained on atenolol 50 q. day. his blood pressures remained fairly well controlled, ranging from 110 to 140 over 60s to 70s. however if his blood pressures remain in the 140 range, the atenolol should be increased to 100 q. day. 6. increased liver function tests: the patient's liver function tests remained elevated throughout his stay on the medicine service. his hepatitis serologies were negative. a right upper quadrant ultrasound was also negative. it is felt that this increase in liver function tests is most consistent with portions of liver that have probably become infarcted due to his hypercoagulable state. an increase in ldh is also consistent with this picture. 7. glucose intolerance: it was noted that the patient had mild glucose intolerance with glucoses ranging from 120 to 135. he was maintained on an insulin sliding scale with good results. discharge medications: 1. atenolol 50 mg one p.o. q. day. 2. lorazepam 0.5 mg tablets to be taken q. 4-6 hours p.r.n. as needed for anxiety. 3. zolpidem 10 mg p.o. q.h.s. as needed for insomnia. 4. ipratropium bromide 0.2 mg per ml, two puffs q. 6 hours. 5. furosemide 20 mg, one p.o. q. day. 6. nystatin swish and swallow for oral thrush. condition on discharge: stable. follow-up plans: the patient is to be discharged to hospital today for further rehabilitation and care. his active issues, which will need to be followed up there, will include: 1. blood pressure control. 2. his pulmonary status has improved considerably here and he is now stable on room air, however the patient continues to have bilateral crackles on lung examination and thus will need physical therapy for his chest. 3. glucose intolerance: the patient will probably need to be maintained on an insulin sliding scale. an oral hypoglycemic can be considered, but given his increased liver function tests, should be avoided. 4. nutrition: the patient should continue on a puree and nectar diet. 5. gi bleed: the patient's hematocrit has been stable for a number of days and it is anticipated that it will continue to remain stable. 6. increased liver function tests: as mentioned above, most likely due to infarction of parts of the liver. 7. dvt: currently anticoagulation cannot be considered given his history of recent gi bleed and continued guaiac positive stools. would follow. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified parenteral infusion of concentrated nutritional
