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 53-year-old woman without significant past medical history, who was in her usual state of health until about two months ago. on , she suffered an l1 burst fracture and left rib fracture secondary to a fall from a ten foot ladder (per patient) or from a second-floor window (per patient's daughter) at home. she was initially seen at an outside hospital two days later, after the incident. she was transferred to immediately for surgical intervention. she had a relatively uneventful perioperative course except for one unit of packed red blood cell transfusion postoperatively. she had a total l1 vertebrectomy, fusion and segmental instrumentation of t12 to l3, cage placement at l1, and autograft during the first surgery. she was evaluated by psychiatry at that time for possible paranoia and questionable suicidal ideation postoperatively. medical workup at that time included a negative rpr, normal thyroid function tests, and a head mri showing possible chronic microvascular ischemia. she was sent to a rehabilitation facility on , in stable condition. about one month later, on , she was readmitted for elective second operation to correct kyphoscoliosis. again she had an uneventful operative course. the second operation included a posterior fusion of t9 to l3, multiple thoracolumbar laminectomies, segmental instrumentation of t9 to l3, and right iliac crest graft. postoperatively, however, she suddenly decompensated in the post-anesthesia care unit while she was receiving a transfusion of one unit of packed red blood cells. she complained of sudden onset of chest pain and shortness of breath with oxygen saturations dropping to 70%, blood pressure dropping to 70/40. she was intubated immediately, and transferred to the surgical intensive care unit for further management. progressive loss of bilateral translucency on chest x-ray and positive anti-hla and anti-granulocyte antibodies on hematological workup were all consistent with trali (transfusion-associated lung injury). while in the surgical intensive care unit, her postoperative course was further complicated with methicillin-sensitive staphylococcus aureus bacteremia, pneumonia, and wound infection (which were documented with positive cultures on ). these events eventually led to a prolonged intubation. after she was started on intravenous oxacillin on , she had very good response, with decreased fever and decreased white blood cell count, as well as clearing of bacteremia which was documented by several blood cultures drawn on later days. she also underwent incision and drainage of posterior wounds on . wound cultures showed decreased colonization of methicillin-sensitive staphylococcus aureus and rare colonies of e. coli. she also had a diagnostic pleural tap on for persistent left pleural effusion. the final culture was negative. she had repeated tte on which showed no vegetation and left ventricular ejection fraction greater than 55%. she also had a ct of the chest, abdomen and pelvis on , which showed improving effusion and normal bowels with old splenic infarct. ct angio was also performed, which showed improving atelectasis and effusion without evidence of pulmonary emboli. she was extubated on , and transferred to medicine on in stable condition. medications: oxacillin, lopressor, subcutaneous heparin, zantac, ativan, haldol, colace, epogen, vitamin d, nasogastric tube feeds allergies: no known drug allergies. social history: works full-time as an insurance underwriter. lives alone.

simple questions. alert and oriented x 1 (person). no apparent distress. head and neck: normocephalic, atraumatic, anicteric, pupils equal, round and reactive to light. neck supple. chest: well-healed left lateral posterior surgical scar, nontender, no erythema. cardiovascular: normal s1 and s2, no murmurs, rubs or gallops. lungs: clear to auscultation bilaterally (anterior and lateral). abdomen: soft, nontender, nondistended. extremities: warm to touch, no edema or cyanosis. distal pulses 2+ bilaterally. no calf tenderness. on venodynes. neurological: cranial nerves ii through xii intact, strength equal bilaterally, sensory intact. psychiatric: appeared disoriented and paranoid. skin intact, no rashes. laboratory data: white cell count 17.9, hematocrit 34.1, platelets 509.

on and were negative. wound culture on showed decreased methicillin-sensitive staphylococcus aureus. stool cultures were negative for c. difficile. catheter tip culture on was negative. chest x-ray on showed decreased left pleural effusion without pneumothorax, decreased congestive heart failure, persistent left basilar atelectasis. ct on showed an old splenic infarct, no abnormal bowel or liver or fluid collection. ct angio showed no evidence of pulmonary emboli, increased left pleural effusion, ground-glass attenuation consistent with volume overload. tte: left ventricular ejection fraction greater than 55%, small pericardial effusion. pleural tap showed no malignant cells. hospital course: while on the medical service, she was continued on oxacillin and showed improvement with decreased white blood cell count and decreased temperature. six weeks of intravenous oxacillin was recommended by infectious disease consult, given the patient's high risk of relapse due to the hardware placed inside the originally-infected wound. a picc line has been placed for the long course of intravenous antibiotic treatment. so far, all blood cultures drawn after starting oxacillin were negative to date. her initial symptoms of tachycardia have also resolved, likely due to a combination of measures including intravenous hydration, improved pulmonary function with incentive spirometer. repeated chest x-ray showed improving atelectasis. repeated cta revealed no evidence of pulmonary emboli. after she was medically stabilized and weaned off all sedatives including haldol, ativan, zantac, her mental status improved dramatically. signs of underlying psychiatric disorder became more obvious. she appeared paranoid and delusional at times, and seemed lacking of insight into her disease. given her questionable history of alcohol abuse and poor nutritional status currently, vitamin b12 and folate and thiamine and a multivitamin were given as supplements. a head ct revealed age-inappropriate atrophy such as seen in increased risk for dementia. psychiatry recommended restarting on haldol to control psychotic symptoms and continue one-to-one sitter until the patient was no longer at high risk of eloping from the hospital. the patient's psychotic symptoms improved with gradually increased doses of haldol. now the patient has been doing well without a one-to-one sitter for more than 24 hours. discharge condition: stable discharge status: rehabilitation facility discharge diagnosis: 1. l1 burst fracture and left rib fracture status post l9 to t3 fusion 2. methicillin-sensitive
