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 61-year-old male who initially presented to the podiatry service after an elective triple arthrodesis of the right foot. he was initially admitted for pain control and was placed on clindamycin postoperatively. he initially did well, but began to develop some low blood pressures into the systolic 90s, which initially responded to iv fluid boluses. these low blood pressures continued with systolics into the 70s-80s, which required several liters of fluid. he also developed a temperature to 101, at which time blood cultures were obtained which revealed positive blood cultures with gram-positive cocci. he also, at that time, had increasing creatinine with a peak of 2.6, and began to develop a new oxygen requirement. he was 92% on 2 liters nasal cannula. he also developed some diarrhea, as well as some mental status changes, and was thought to be encephalopathic. the medical consult resident was , and the patient was then transferred to the medical team. past medical history: 1. hypertension. 2. cad. 3. history of asthma. 4. history of osteoporosis. 5. gerd. 6. ?history of crohn's disease, although there are no records of tissue biopsy, and no previous history of diarrhea, or abdominal surgeries. 7. previous history of metastatic melanoma to the lung. 8. history of hiv with the last cd4 count of 595 in . 9. history of cataracts. 10.history of low t4. 11.history of dilated cardiomyopathy secondary to il-2 treatment for his melanoma. this cardiomyopathy later resolved. 12.peripheral neuropathy. 13.hypertriglyceridemia. 14.allergic rhinitis. allergies: 1. sulfa. 2. cipro. 3. penicillin. medications on transfer: 1. vancomycin. 2. flagyl. 3. tums. 4. percocet. 5. lisinopril. 6. heparin subcu. 7. imodium. 8. testosterone patch. 9. stavudine. 10.lamivudine. 11.abacavir. 12.zyrtec. 13.dipentum. 14.allopurinol. 15.gemfibrozil. 16.nifedipine. 17.cr30 qd. 18.protonix. 19.synthroid. 20.montelukast. 21.gabapentin. vital signs on transfer: t-max 100.1, blood pressure ranging between 72-100 systolic/50s, heart rate between 86 and 114, respiration rate 20, satting 93% on /2 liters nasal cannula. ins and outs - 4,400 in with 300 out. bowel movements x 6. general appearance: the patient is older than stated age, sleepy but arousable, in no apparent distress. head and neck exam: anicteric. mucous moist. no jvd noted. lungs: bilateral lower lobe crackles. cardiac exam: tachycardic with ii/vi systolic ejection murmur with radiation to the apex. abdomen: soft, nontender, nondistended. there was no cva tenderness. extremities: right lower extremity in a cast. no clubbing, cyanosis or edema. neuro exam: he was alert, appears somewhat confused, with notable asterixis on exam. labs on transfer: notable for a white count of 11.4 down from 14, hematocrit 33.1, mcv 104, platelets 192. chem-7 with a sodium of 136, k 4.6, chloride 108, bicarb 16, bun 54, creatinine 2.6 up from 2.5, glucose 126, calcium 8.2, mag 1.9, phos 4.4. coags were notable for an inr of 1.4. blood cultures at this time were notable for gram-positive cocci in pairs and clusters. previous c. diff toxin was negative. ekg appeared sinus with a rate of 114. no st elevation. no clear markers of ischemia or tamponade were noted. hospital course - 1) infectious disease: the patient appeared to be in sepsis which was likely due to globalized sepsis from his methicillin sensitive staphylococcus aureus which later grew out of his blood. the source of this was somewhat unclear. it was initially thought to be related to his foot surgery, although his foot appeared clean per podiatry notes. he initially was placed on vancomycin, flagyl and gentamicin. he was transferred to the intensive care unit initially where he received several liters of iv fluids, and antibiotics were continued. he did well and maintained his blood pressure with improvement in his creatinine and pulmonary status. he was transferred back to the floor. while back on the floor, his gentamicin was dc'd. he was afebrile the day of discharge, and follow-up cultures continued to remain negative. he received a tte and later a tee to evaluate for endocarditis, which showed no evidence of thrombus or vegetation. a picc line was placed for a 14-day course of vancomycin, as the patient could not receive penicillin derivatives or fluoroquinolones. 2) diarrhea: based on his clinical history, there was a very high suspicion for c. diff infection as the cause of the patient's diarrhea. he had been on clindamycin as an outpatient and was continued on clindamycin as monotherapy as an inpatient. his clindamycin was dc'd, and he had numerous c. diff studies for toxin a which were negative. a c. diff toxin b assay was sent which was not available at the time of discharge. he was treated empirically for c. diff colitis with a 14-day course of flagyl with gradual improvement in his diarrhea. 3) cardiovascular: during his initial presentation to the medical team, the patient developed atrial fibrillation with rapid ventricular response into the 150s. he was initially given iv lopressor and then po lopressor with adequate response while in the intensive care unit, and his heart rate was maintained. approximately 3 days after the onset of his atrial fibrillation, he was sent for tee and was cardioverted successfully. he was placed on coumadin, became therapeutic, and was discharged on a 6-week course of coumadin, and to have his inr checked at rehab. 4) renal: he developed what appears to be acute renal failure secondary to sepsis, which resolved with the resolution of his sepsis and aggressive iv fluid management. 5) pulmonary: he had an initial o2 requirement which was likely secondary to his sepsis. he did not have any evidence of systolic congestive heart failure on echo, and his transient o2 requirement was likely secondary to capillary leak which later resolved. he did not require intubation during his hospital course and was satting well on room air at the time of discharge. 6) podiatry: his postop wound remained clean throughout his hospital course, and he was discharged in a cast to be followed up in days, and to be changed by podiatry. condition at discharge: stable. discharge status: extended care facility. discharge diagnoses: 1. staph aureus bacteremia. 2. diarrhea possibly secondary to clostridium difficile. 3. triple arthrodesis of right foot. 4. atrial fibrillation with rapid ventricular response status post cardioversion. 5. congestive heart failure. 6. acute renal failure. 7. sepsis. 8. transient encephalopathy. discharge medications: 1. tylenol prn. 2. abacavir 300 mg . 3. gabapentin 300 mg tid. 4. montelukast 10 mg qd. 5. lamivudine 150 mg . 6.

was told to follow-up with dr. of podiatry within 5-7 days after his discharge to change his right leg cast. 2. he also was told to follow-up with his primary care physician 1-2 weeks of discharge. 3. he was also given an appointment with dr. of infectious disease, . discharge instructions: he was given explicit instructions to take all medications as prescribed and told to remain nonweightbearing on his right lower extremity until his follow-up appointment with dr. . he was told that if he had any further episodes of fever, any lightheadedness, severe leg pain, worsening diarrhea, or had any other concerning symptoms, that he should seek immediate medical attention. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified diagnostic ultrasound of heart
