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 history between and , please see the prior discharge summary. this discharge summary covers from through . hospital course: the patient was diagnosed with acute myelogenous leukemia and underwent induction with ara-c and idarubicin 7+3. his main issues were, in summary: 1. hematology/oncology: the patient demonstrated an ablated marrow which was expected and anticipated after undergoing the chemotherapy. follow-up marrow results done to show if there was appropriate recovery of the bone marrow were still pending, though clinical picture suggested that the normal cells have returned; though, the question as to whether there are additional leukemoid cells has not yet been determined. the patient was to follow up in about one week's time to begin his consolidation chemotherapy which was to be done as an outpatient by dr. . the patient received multiple platelet and blood transfusions as supportive treatment for his ablative process as associated with his chemotherapy. 2. infectious disease: the patient's primary issue was that he developed a vancomycin-resistant enterococcus faecalis infection in his blood which showed positive growth from through ; thus, five days. from through , all cultures were subsequently negative. the patient was treated first with linezolid and then switched to synercid because the enterococcus was found to be sensitive to that antibiotic, and the concern about linezolid was that it had myelosuppressive effects. the patient will undergo 14 days of therapy of synercid, dating from the point at which he was found to have negative blood cultures on , so that he will have his last day of synercid (as mentioned before of 600 mg intravenously q.8h.) on . the patient was also treated with acyclovir 400 mg p.o. t.i.d. for his herpes. he was covered empirically with other antibiotics as per protocol related to being neutropenic and then having an neutropenic fever until cultures were identified. it should be noted that stool culture also showed vancomycin-resistant enterococcus faecalis; however, his catheter tip remained negative. fungal cultures were negative. the patient was clostridium difficile negative, and he did not have any vegetations founds on his heart valves by both transthoracic and transesophageal echocardiograms; making us confident that he did not have endocarditis. the patient was followed by the infectious disease service. the fellow was syngevony wadwa, and the attending was . the patient also had what looked to be a tooth in his right maxillary sinus leading to almost complete obstruction of the (omu) ostiomeatal unit. the ear/nose/throat service performed a removal of that tooth particle and drainage of the sinus, and that was done on , , with no complications and minimal blood loss. 2. endocrine: the patient has baseline addison disease, though he was consistently hypokalemic. he was maintained with prednisone and hydrocortisone throughout his admission. for a time, he had received hydrocortisone 25 mg intravenously q.8h. he was then converted to prednisone 10 mg p.o. q.a.m. and 5 mg p.o. q.p.m. then, before the surgery, 100 mg intravenously q.8h., down to 50 mg intravenously q.8h., and eventually back down to prednisone 5 mg q.a.m. and 2.5 mg q.p.m. the patient was keep off of his florinef until the day before discharge when he was started on 0.025 mg p.o. q.d. and then discharged on his regular dose of 0.1 mg p.o. q.d. he was also supplemented with potassium chloride for his consistent low potassium of 30 meq of p.o. b.i.d. because he was unwilling or unable to take the potassium by mouth during the hospital stay, he was given potassium chloride as replacement fluids. however, again, on discharge, he left with the prescription of potassium chloride 30 meq p.o. b.i.d. for nausea and vomiting, the patient was given reglan and carafate which he said did not help him particularly. he also was given ativan 1 mg to 2 mg p.o. q.8h. which he was discharged on also with his discharge medications. he was given a 3-day prescription of that as assistance if he were to feel nauseated. 3. code status: the patient remained full code during his admission. discharge status: he was discharged to the home of his girlfriend while he recovered and was being followed for his acute myelogenous leukemia. discharge followup: the patient was to follow up with dr. on , , for evaluation and planning for his next round of consolidation chemotherapy. discharge diagnoses: (the patient was discharged with a diagnosis of) 1. acute myelogenous leukemia. 2. pulmonary embolism. 3. addison disease. medications on discharge: (he was discharged on the following medications) 1. synercid 600 mg intravenously q.8h. (through ). 2. heparin 100 units flush through the peripherally inserted central catheter. 3. d-5-w flushes 5 cc through the peripherally inserted central catheter. 4. florinef 0.1 mg p.o. q.d. 5. prednisone 5 mg p.o. q.a.m. and 2.5 mg p.o. at 4 p.m. 6. acyclovir 400 mg p.o. t.i.d. 7. potassium chloride 30 meq p.o. b.i.d. , m.d. dictated by: medquist36 procedure: injection or infusion of cancer chemotherapeutic substance intracranial ventricular shunt or anastomosis intranasal antrotomy ethmoidectomy frontal sinusotomy diagnoses: thrombocytopenia, unspecified bacteremia streptococcus infection in conditions classified elsewhere and of unspecified site, streptococcus, group d [enterococcus] other pulmonary embolism and infarction acute myeloid leukemia, without mention of having achieved remission foreign body in nose
