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: allergies: penicillins / aspirin / biaxin attending: chief complaint: r knee pain major surgical or invasive procedure: : s/p right total knee replacement history of present illness: r knee oa past medical history: gerd asthma diabetes mellitus (per patient -

ct head: 1. no acute intracranial hemorrhage. 2. bifrontal white matter hypodensity, left greater than right, which could be related to chronic small vessel ischemic disease, but mild acute edema cannot be excluded. if edema is present, it could be related to watershed infarction, given recent surgery, though other etiologies cannot be excluded.since mri is contraindicated in the immediate postoperative setting, shortinterval follow-up ct is recommended to assess for any progression of thesefindings. if clinically indicated, a cta of the head may be obtained toexclude large vascular occlusion. . - cta chest: no acute pe to the segmental level. . - echocardiogram: the left atrium is mildly dilated. no atrial septal defect is seen by 2d or color doppler. the right atrial pressure is indeterminate. left ventricular wall thicknesses are normal. the left ventricular cavity size is normal. there is mild regional left ventricular systolic dysfunction with infero-lateral akinesis. there is no ventricular septal defect. right ventricular chamber size and free wall motion are normal. the aortic valve leaflets (3) are mildly thickened but aortic stenosis is not present. no aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. the tricuspid valve leaflets are mildly thickened. there is mild pulmonary artery systolic hypertension. there is no pericardial effusion. 01:16pm blood wbc-9.5 rbc-3.49* hgb-11.0* hct-31.6* mcv-91 mch-31.4 mchc-34.6 rdw-14.1 plt ct-203 03:40am blood wbc-9.6 rbc-2.62* hgb-8.2* hct-24.2* mcv-92 mch-31.4 mchc-33.9 rdw-14.2 plt ct-192 11:26am blood wbc-14.1* rbc-3.19* hgb-10.0* hct-29.5* mcv-93 mch-31.5 mchc-34.0 rdw-14.1 plt ct-213 07:12am blood wbc-10.0 rbc-3.35* hgb-10.3* hct-30.8* mcv-92 mch-30.6 mchc-33.4 rdw-14.3 plt ct-230 05:00pm blood wbc-10.9# rbc-3.53* hgb-10.8* hct-32.8* mcv-93 mch-30.6 mchc-33.0 rdw-13.9 plt ct-236 10:55am blood pt-15.1* inr(pt)-1.3* 04:25pm blood pt-17.9* inr(pt)-1.6* 03:40am blood pt-16.7* ptt-28.3 inr(pt)-1.5* 11:26am blood pt-16.0* ptt-27.8 inr(pt)-1.4* 10:55am blood glucose-108* urean-10 creat-0.8 na-138 k-3.8 cl-103 hco3-27 angap-12 03:40am blood glucose-92 urean-8 creat-0.8 na-142 k-3.7 cl-105 hco3-30 angap-11 04:25pm blood ck(cpk)-515* 03:40am blood alt-82* ast-57* ld(ldh)-206 ck(cpk)-487* alkphos-68 totbili-0.6 11:26am blood alt-127* ast-120* ld(ldh)-390* ck(cpk)-175 alkphos-81 totbili-0.6 04:25pm blood ck-mb-3 ctropnt-<0.01 03:40am blood ck-mb-3 ctropnt-0.03* 11:26am blood ck-mb-3 ctropnt-<0.01 probnp-113 03:40am blood albumin-2.9* calcium-8.1* phos-3.2 mg-1.9 11:26am blood albumin-3.5 calcium-8.7 phos-4.2 mg-1.9 brief hospital course: the patient was admitted to the orthopaedic surgery service and was taken to the operating room for above described procedure. please see separately dictated operative report for details. the surgery was uncomplicated and the patient tolerated the procedure well. patient received perioperative iv antibiotics. postoperative course was remarkable for the following: 1. course: on pod#1, patient developed sudden loss of consciousness with bilateral hand-twitching. code blue was called and patient was intubated for air protection. ct head was negative for acute bleed but showed bifrontal white matter hypodensity, left greater than right likely related to chronic small vessel ischemic disease. patient had rapid recovery of mental status. neurology was consulted and felt that patient's symptoms were more likely to be from transient hypotension and unlikely to be stroke. cta of the chest of performed which ruled out pe. patient was extubated the same afternoon. mental status was throughout. cardiac enzymes were stable and echocardiogram showed regional lv systolic dysfunction new compared to prior exam. most likely cause of episode was transient hypotension post-operatively, likely from pain medications. patient transferred back to the orthopedics service. 2. post-op anemia - pod #2 hct 24.2, asymptomatic -> transfused 2 units prbcs otherwise, pain was initially controlled with a pca followed by a transition to oral pain medications on pod#1. the patient received lovenox for dvt prophylaxis starting on the morning of pod#1. the foley was removed on pod#2 and the patient was voiding independently thereafter. the surgical dressing was changed on pod#2 and the surgical incision was found to be clean and intact without erythema or abnormal drainage. the patient was seen daily by physical therapy. labs were checked throughout the hospital course and repleted accordingly. at the time of discharge the patient was tolerating a regular diet and feeling well. the patient was afebrile with stable vital signs. the patient's hematocrit was acceptable and pain was adequately controlled on an oral regimen. the operative extremity was neurovascularly intact and the wound was benign. the patient's weight-bearing status is weight bearing as tolerated on the operative extremity. ms. is discharged to rehab ( ) in stable condition. medications on admission: advair 500/50 , albuterol prn, diltazem 300mg daily, fosamax 70mg weekly, glipizide 5mg prn, lisinopril 40mg daily, ativan 1mg prn, mvi, accolate 20mg , pravastatin 20mg daily, prilosec 20mg , roxicet prn, theophylline 300mg daily, vit c, vit d discharge medications: 1. enoxaparin 40 mg/0.4 ml syringe sig: one (1) syringe subcutaneous once a day for 4 weeks. disp:*28 syringe* refills:*0* 2. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 3. fluticasone-salmeterol 500-50 mcg/dose disk with device sig: one (1) disk with device inhalation (2 times a day). 4. lorazepam 0.5 mg tablet sig: 1-2 tablets po q8h (every 8 hours) as needed for anxiety. 5. ferrous sulfate 300 mg (60 mg iron) tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*0* 6. omeprazole 20 mg capsule, delayed release(e.c.) sig: one (1) capsule, delayed release(e.c.) po bid (2 times a day). 7. pravastatin 20 mg tablet sig: two (2) tablet po daily (daily). 8. senna 8.6 mg tablet sig: one (1) tablet po bid (2 times a day). 9. oxycodone 5 mg tablet sig: 1-2 tablets po q4h (every 4 hours) as needed for pain. disp:*90 tablet(s)* refills:*0* 10. acetaminophen 325 mg tablet sig: two (2) tablet po q6h (every 6 hours). 11. multivitamin tablet sig: one (1) cap po daily (daily). 12. calcium 600 + d(3) 600 mg(1,500mg) -400 unit tablet sig: one (1) tablet po once a day. discharge disposition: extended care facility: -
