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: no known allergies / adverse drug reactions attending: chief complaint: headaches major surgical or invasive procedure: : left craniotomy and burr hole for evacuation of subdural history of present illness: this is a 75 year old man with a history of afib on coumadin initially presented with 3 days of headache. he denied numbness, weakness, visual changes, dizziness, falls or trauma. ct head revealed left sdh. he was managed conservatively, coumadin was held and he followed up in the clinic. repeat ct revealed worsening sdh so he was scheduled for elective evacuation. past medical history: afib s/p ablation, high chol, s/p thyroidectomy,gerd, htn social history: he is a retired fisherman, lives with wife s/p cva 4 yrs ago at home with daily caretaker, 3 sons who live in area. + etoh family history: non contributory physical exam: on admission: o: t:97.9 bp: 116/65 hr:56 r 16 o2sats 98% ra gen: wd/wn, comfortable, nad. heent: pupils: bilat eoms full neck: supple. extrem: warm and well-perfused. neuro: mental status: awake and alert, cooperative with exam, normal affect. orientation: oriented to person, place, and date. recall: objects at 5 minutes. language: speech fluent with good comprehension and repetition. naming intact. no dysarthria or paraphasic errors. cranial nerves: i: not tested ii: pupils equally round and reactive to light, 3 to 2 mm bilaterally. visual fields are full to confrontation. iii, iv, vi: extraocular movements intact bilaterally without nystagmus. v, vii: facial strength and sensation intact and symmetric. viii: hearing intact to voice. ix, x: palatal elevation symmetrical. : sternocleidomastoid and trapezius normal bilaterally. xii: tongue midline without fasciculations. motor: normal bulk and tone bilaterally. no abnormal movements, tremors. strength full power throughout. no pronator drift sensation: intact to light touch bilaterally. reflexes: no clonus toes downgoing bilaterally handedness right discharge exam: patient with baseline left facial twitching. he is alert oriented x 3, perrl, does have right facial droop. he has no right pronator drift. strength 5/5 bilaterally. sensory intact. incision is clean/dry and intact. her incision is clean and dry with staples in place. pertinent results: ct head - since the previous study, the subdural on the left side has increased in size with 15 mm in thickness in the left frontal and 12 mm in thickness in the left occipital region. there is mass effect on the adjacent brain and the ventricle but no significant midline shift or herniation identified. : ct head- 1. status post right hemicraniotomy and evacuation of a moderate left subdural hematoma with new hyperdense material collecting along the left frontal and occipitoparietal lobes may be postsurgical or interval hemorrhage. there is persistent effacement of the left cerebral sulci and 4 mm rightward shift of normally midline structures, slightly decreased from . 2. no evidence of acute infarction. 3. stable left centrum semiovale chronic infarct ct head - 1. status post right frontotemporal craniotomy with stable hyperdense fluid collections along the left frontal and occipitoparietal lobes from which may be post-surgical or alternanively, interval hemorrhage. effacement of the left cerebral sulci and 4 mm rightward shift of normally midline structures is unchanged. 2. increased size of subcutaneous fluid collection at the craniotomy site from measuring 1 cm in thickness. 3. no evidence of acute infarction. stable left centrum semiovale chronic infarct. - ct head - status post left craniectomy and drain removal with a left subdural gas/fluid/blood products collection with similar mass effect compared to the prior day's exam. head ct- stable mri brain 1. no evidence of acute infarct. 2. stable left frontoparietal subdural hematoma with stable mass effect and minimal midline shift. stable subarachnoid hemorrhage involving the left frontal, temporal and parietal lobes. ct head impression: 1. little change in comparison to the study from yesterday, with stable appearance of left frontoparietal subdural hematoma, with overlying subarachnoid hemorrhage; no new focus of hemorrhage. 2. no abnormal enhancing foci suggestive of infection. note added in attending review: there is relatively uniform enhancement of the subgaleal scalp, overlying the craniotomy site. this was also present on the mr examination of roughly 23 hours earlier, where no rim-enhancing fluid collection to suggest abscess is seen. this likely represents expected post-operative change, but should be closely correlated with physical examination, as with this imaging appearance, cellulitis cannot be entirely excluded. brief hospital course: mr. presented and underwent left craniotomy and left burr hole for sdh evacuation. surgery was without complication but the patient was noted to have significant bleeding/oozing. a subdural drain was left in place. he was extubated and transferred to the icu for neurological monitoring. post op head ct revealed good evacuation. a hematology consult was requested for evaluation of his clotting. and they recommended no further work-up. bleeding was assumed likely secondary to previous coumadin. serial ct scans of the head demonstrated stable post op pneumocephalus and tiny residual left sdh without siginficant mass effect. on his drain was removed without difficulty. pt/ot were consulted for outpatient disposition and they recommended home with outpatient pt. on he had a right hemiparesis and speech difficulty. his discharge was canceled and he was transferred to the step down unit. there was a question as to if this was a seizure. his exam improved and he had one episode of emesis overnight. as a result of his symptoms a repeat head ct was performed and revealed no new hemorrhage or acute intracranial abnormality. he also underwent mri which showed no evidence of infarct. ct head with contrast ruled out empyema overnight . his eeg from this day was without seizure activity. he was getting screened for rehab on . he was offered a bed on and was transfered. medications on admission: amiodarone, simvastatin, lisinopril, levothyroxine, prevacid, recent coumadin discharge medications: 1. acetaminophen 325 mg tablet : 1-2 tablets po q6h (every 6 hours) as needed for pain, t>38.5. 2. docusate sodium 100 mg capsule : one (1) capsule po bid (2 times a day). 3. amiodarone 200 mg tablet : one (1) tablet po bid (2 times a day). 4. simvastatin 10 mg tablet : two (2) tablet po daily (daily). 5. levothyroxine 25 mcg tablet : 0.5 tablet po daily (daily). 6. lisinopril 10 mg tablet : one (1) tablet po daily (daily). 7. senna 8.6 mg tablet : one (1) tablet po daily (daily). 8. bisacodyl 5 mg tablet, delayed release (e.c.) : two (2) tablet, delayed release (e.c.) po daily (daily). 9. insulin regular human 100 unit/ml solution : two (2) units injection asdir (as directed): see sliding scale. 10. tramadol 50 mg tablet : one (1) tablet po q4h (every 4 hours) as needed for headache, pain. 11. levetiracetam 500 mg tablet : three (3) tablet po bid (2 times a day). 12. oxycodone-acetaminophen 5-325 mg tablet : 1-2 tablets po q4h (every 4 hours) as needed for headache. 13. metoprolol tartrate 25 mg tablet : 0.5 tablet po bid (2 times a day): hr <60, sbp <110 . 14. lansoprazole 30 mg tablet,rapid dissolve, dr : one (1) tablet,rapid dissolve, dr daily (daily). 15. hydralazine 25 mg tablet : one (1) tablet po q6h (every 6 hours) as needed for sbp>160. 16. heparin (porcine) 5,000 unit/ml solution : 5000 (5000) units injection tid (3 times a day). discharge disposition: extended care facility: rehabilitation and skilled nursing center - discharge diagnosis: left subdural hematoma hypertension atrial fibrillation discharge condition: mental status: clear and coherent. level of consciousness: alert and interactive. activity status: ambulatory - independent. discharge instructions: general instructions *we have held coumadin. your should not restart coumadin until cleared by your cardiologist and dr. . your previous regimen was: coumadin 2.5mg m,w,f, sa and 5.0mg tu,th, ?????? you rehab should check your incision daily for signs of infection. you staples should be removed at rehab on . ?????? take your pain medicine as prescribed. ?????? exercise should be limited to walking;
