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 79 year old male with a past medical history significant for coronary artery disease, hypertension, hypercholesterolemia, end-stage renal disease, on hemodialysis, and subdural hematoma diagnosed in . the patient was admitted to an outside hospital for slurred speech and right sided weakness noted by a health aide following the patient's hemodialysis. the patient was transferred to for workup of confusion and fever with his history of subdural hematoma. the ct scan showed minimal change in the patient's known subdural hematoma. chest x-ray, however, showed bilateral consolidation, with gram positive cocci in the sputum. the patient was thus dosed with ceftriaxone, levofloxacin and vancomycin in addition to receiving a one liter normal saline bolus. the patient was dialyzed 2.5 liters for concern of fluid overload. following hemodialysis, the patient became hypotensive to the 70s, tachypneic and diaphoretic with electrocardiographic changes showing diffuse st-t wave changes. the patient was thus started on dopamine and given a 750 cc normal saline bolus. he further required the addition of neo-synephrine to support his blood pressure. his heart rate subsequently increased and his st-t wave changes worsened, so his dopamine was stopped and these changes resolved. the patient was subsequently seen by cardiology in the emergency room and an echocardiogram was done, and his ischemia was felt to be consistent with demand ischemia. past medical history: 1. coronary artery disease, status post coronary artery bypass grafting times four vessels in , percutaneous transluminal coronary angioplasty in . 2. congestive heart failure, left ventricular ejection fraction 20% to 25%. 3. end-stage renal disease, on hemodialysis. 4. status post left carotid endarterectomy in . 5. status post bilateral femoral bypass. 6. status post right below the knee amputation. 7. subdural hematoma in 200, status post drain. 8. hypertension. 9. hypercholesterolemia. 10. peptic ulcer disease. 11. history of methicillin resistant staphylococcus aureus. allergies: morphine. medications on admission: imdur 30 mg p.o.q.d., aciphex 20 mg p.o.q.d., phos-lo 667 mg p.o.t.i.d., nephrocaps one p.o.q.d., aspirin 81 mg p.o.q.d., zoloft 75 mg p.o.q.d., zocor 10 mg p.o.q.d., ocuvite one p.o.q.d., zinc and b12. physical examination: on physical examination, the patient had a temperature of 101.8, heart rate 80 to 110s, respiratory rate 24 to 28 and oxygen saturation 97% on nonrebreather. general: alert, cooperative, tachypneic. head, eyes, ears, nose and throat: extraocular movements intact, pupils post surgical bilaterally, anicteric sclerae. neck: supple, no lymphadenopathy, no jugular venous distention. cardiovascular: regular rate and rhythm, normal s1 and s2, ii/vi holosystolic murmur at left lower sternal border, positive s3 which resolved over this admission. lungs: coarse breath sounds throughout. abdomen: soft, nontender, nondistended, no hepatosplenomegaly. extremities: right below the knee amputation, 2+ left posterior tibialis pulse, cool, no mottling. neurologic examination: alert and oriented times three, strength 4/5 in upper extremities bilaterally, moved left lower extremity without difficulty. laboratory data: admission white blood cell count 9.2, hematocrit 37.5, platelet count 177,000, inr 1.5, partial thromboplastin time 33.3, sodium 136, potassium 4.6, chloride 92, bicarbonate 26, bun 48, creatinine 6.4, glucose 147, most recent white blood cell count 8.2. cks have been trending down, last ck was 38 on , previous cks 104, 74, and 72. vancomycin level from today was 16.1. sputum from showed greater than 25 polymorphonuclear neutrophils and 2+ gram positive cocci in pairs and clusters. blood cultures from ....... and show no growth to date. chest x-ray from showed bibasilar consolidation, no congestive heart failure. the ct scan from showed a subacute subdural hematoma, left lateral, slightly increased since but no herniation and no acute hemorrhage. echocardiogram done in the emergency room showed inferior, inferolateral hypokinesis with a left ventricular ejection fraction of 20% to 25% with 1 to 2+ mitral regurgitation, systolic pressures of 38. hospital course: 1. sepsis: the patient was admitted with sepsis presumed secondary to pneumonia. he was continued on intravenous levofloxacin and vancomycin during his hospital stay. his white blood cell count has remained stable and he has remained afebrile. the plan is to continue antibiotics for a 12 day course of levofloxacin and vancomycin for a chest x-ray with bibasilar consolidation and a sputum culture positive for gram positive cocci in pairs in clusters. 2. hypotension: the patient had an acute blood pressure drop following hemodialysis in the emergency room, requiring pressor support. he was initially started on neo-synephrine and dopamine. the dopamine was stopped for demand ischemia. the patient was subsequently changed from neo-synephrine to levophed and vasopressin for suspected sepsis as the cause of his low blood pressure. he was maintained on these medications until successfully weaned off on . his blood pressure has remained stable over the course of today in addition to his challenge with hemodialysis today. 3. cardiac ischemia: the patient had a positive troponin leak on admission. an echocardiogram done in the emergency room, ischemia thought to be secondary to demand ischemia. cks were cycled and were trending down. the patient was maintained on aspirin and a statin, all chronotropic pressors were avoided following his diagnosis. the patient was carefully bolused to maintain his blood pressure due to the fact that he is at extreme risk for congestive heart failure. 4. pneumonia: the patient had bibasilar consolidations on chest x-ray, with sputum culture positive for 2+ gram positive cocci in pairs and clusters. he is being maintained on a 12 day course of levofloxacin and vancomycin considering his history of methicillin resistant staphylococcus aureus. 5. end-stage renal disease: the patient was hemodialyzed on and 12, . he is regularly dialyzed at renex dialysis center. 6. change in mental status: the patient was transferred to for a change in mental status. a neurology consult was obtained and recommendations were made for an electroencephalogram, which was unrevealing. there was minimal further improvement in the patient's mental status following the improvement of his fever. it is the opinion of the neurology staff that likely metabolic insult may have explained the patient's acute mental status. discussions with the patient's family revealed that he is at his baseline, and no further management of his mental status is indicated. 7. code status: the patient is "do not resuscitate", "do not intubate". 8. communication: during the patient's stay in the intensive care unit, the staff have been communicating with the patient's son and other family members. condition on discharge: stable. discharge diagnoses: sepsis. pneumonia. discharge
