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: this is a 48 year old female status post right total knee replacement in for osteoarthritis who was discharged to rehabilitation with an uncomplicated postoperative course. in she developed a right septic knee and arthrostomy was performed at hospital. on , a revision to the right total knee replacement was performed and the second stage removal of antibiotic cement. in , incision and drainage of the right knee hematoma was performed. over this period (from to ) the patient had been on oxacillin through a picc line. a temperature spike two to three weeks ago lead to removal of the picc line and a new picc line was placed in the right arm and the patient was started on vancomycin on . he was also on low dose coumadin since surgery in . the coumadin was recently stopped two weeks prior to this current admission. the patient also completed a course of levaquin for left lower lobe pneumonia approximately one month prior to admission. five days prior to admission the patient had reported acute onset of shortness of breath while sitting in a chair. the shortness of breath has been episodic since then with oxygen saturation dropping to the high 80s at . he reports occasional right calf pain but no calf or sputum currently. the patient feels currently short of breath and exhibits dyspnea on exertion. she had an episode of chest pain the day of admission with pressure lasting hours with intermittent sharp, stabbing pains, also episodic diaphoresis and regurgitation with temperature up to 102.8 one week prior to admission. past medical history: 1. morbid obesity; 2. severe degenerative joint disease, status post total knee replacement; 3. depression; 4. anxiety; 5. substance; 6. hepatitis c; 7. anemia; 8. nephrolithiasis; 9. hypertension; 10. hernia repair; 11. status post cholecystectomy; 12. questionable history of methicillin-resistant staphylococcus aureus. admission as an outpatient: diltiazem, lisinopril, wellbutrin, protonix, effexor, iron sulfate, oxy-contin, oxycodone, trazodone, compazine, vancomycin allergies: iodine social history: tobacco use for 35 years, pack per day. there is a history of ethanol use and intravenous drug use including heroin, cocaine and other illicit drugs. the patient currently lives at . physical examination: temperature 98.4, blood pressure 108/52, heartrate 103, respiratory rate 14, oxygen saturation 98% on room air. general: this is a very obese female. head, eyes, ears, nose and throat; moist mucous membranes, oropharynx clear. neck: jugulovenous distension not present, supple. chest: clear to auscultation bilaterally. cardiovascular: regular rate and rhythm, normal s1 and s2, no murmurs, rubs or gallops. abdomen: marked surgical scars and large ventral hernia. extremities: there is a right picc line, no erythema, negative for hommas sign. no tenderness on palpation and no asymmetric edema. laboratory data: laboratory data on examination revealed sodium 152, potassium 4.5, chloride 98, bicarbonate 23, bun 16, creatinine 1.0, glucose 109, white blood cell count 15.7 with a differential of 74% neutrophils, 0 bands, 14 lymphocytes, hematocrit 31.5, compared to a prior 38 and platelets 187. chest x-ray was negative for pneumonia or congestive heart failure. lower extremity noninvasives were performed and were negative. v/q scan was negative. electrocardiogram was non-contributory. hospital course: the patient was admitted to medicine. there was a strong suspicion for a pulmonary embolus given the recent history of surgical procedures and the morbidity status of the patient. a computerized tomographic angiography was performed and revealed a right segmental defect which was attributed as a possibility. the patient was started on heparin and was evaluated by cardiac enzymes for myocardial infarction. the patient ruled out for myocardial infarction and echocardiogram showed an ejection fraction of 35%, mildly dilated left atrium, moderately dilated right atrium, mildly dilated left ventricle and moderate global left ventricle hypokinesis. on , three out of four blood cultures came back positive for gram negative rods and the patient was started on zosyn. a computerized tomography scan of the pelvis demonstrated a right iliacus, iliopsoas abscess or myositis. on , the patient experienced worsening right groin and abdominal pain with now the pain radiating to the right flank. he became hypotensive with a systolic blood pressure in the 70s and a hematocrit of 25. a computerized tomography scan of the pelvis with contrast revealed a large retroperitoneal hematoma and the patient was transferred to the medicine intensive care unit service. the hematocrit further dropped to 20 and surgical consult was asked for. also interventional radiology consulted. ptt was 100 that morning and the patient was administered packed red blood cells and 4 units of fresh frozen plasma. a left subclavian line and a right arterial line were placed. the patient was treated with vancomycin and imipenem. because of the falling hematocrit the patient received additional packed red blood cell transfusions. eventually on , the hematocrit stabilized and the patient was transferred again back to the floor. at that time, the vital signs revealed temperature 98.7, blood pressure 140/80, heartrate 88, respiratory rate 20 and oxygen saturation 99% with 4 liters of oxygen. subsequently, the patient's hematocrit was followed every 12 hours and remained stable. antibiotics were continued with vancomycin discontinued on . repeat abdominal computerized tomography scan demonstrated stable retroperitoneal hematoma. on , the patient complained of increased abdominal pain. at this point the pain medications were oxy-contin, oxycodone, morphine prn, tylenol and these were increased. pain consult was called but was unable to see the patient because the patient was repeatedly outside of her room in the building, in order to smoke. at the point of dictation of this summary, the plan is for the patient to have picc line installed on the morning of and to be discharged to a rehabilitation facility on the same day. the plan is for the patient to continue the antibiotics, in particular meropenem for a total of four to six weeks pending repeat of the abdominal computerized tomography scan and repeat of the blood cultures.
