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: patient recorded as having no known allergies to drugs attending: chief complaint: s/p motorcycle crash major surgical or invasive procedure: none history of present illness: 49 yo left handed man with a pmh significant for a-fib (on warfarin), embolic stroke (seemingly r ant div mca), cad s/p stents and htn. he was reportedly riding his motorcycle today (after having 2-3 beers) and states that a car swerved into his causing him to swerve and "lay his bike down." he is not sure how he hit his head. he states having a memory for the entire event and denies any loss of consciousness or anything resembling ictal activity. he was taken to hospital where he was noted to have a right frontal and right anterior temporal pole sdh. he was also noted to have a left c5 facet fracture; he received 5mg of vitamin k and 2 units of ffp and was then transferred to for further management. past medical history: afib, cad s/p 5 stents psh: 5 stents family history: noncontributory physical exam: upon presentation: 97 bp 157/94 hr 83 r 23 general: in hard collar. mental status examination: oriented to hospital, . oriented to . fluent and prosodic speech. repetition intact. follows three step commands briskly. moyb done briskly and correctly. registers 4 objects immediately and recalls all 4 at 5 min. cranial nerves: peerl 4->2mm, vff. eom full. v1-v3 intact to pp, lt and temp. face symmetric. tongue and palate midline. no dysarthria or dysphonia. motor examination: no cogwheeling or tremor. no drift. finger and toe tapping symmetric. no pronator drift. in all extremities with exception of some pain limitation at left shoulder. coordination: fnf without dysmetria. reflexes: 2+ and symmetric with downgoing toes. pertinent results: : cxr: no acute traumatic process. ct c-spine: anterior posteriorly oriented lucencies through the c4 left lateral facet that is suspicious for possible fracture. the thyroid gland demonstrates small punctate calcifications on the right, correlation with thyroid ultrasound is advised if clinically warranted in a non emergent basis. ct head: 4 mm in transverse dimension acute subdural hemorrhage layering along the right frontal lobe, with subjacent mass effect of the right frontal sulci. in addition, a 6-mm focus of extra-axial hemorrhage seen adjacent to the right temporal lobe. continued followup is recommended. ct torso: 1. no evidence of traumatic injury to abdomen or pelvis. 2. bilateral inferior renal scarring from prior infection or infarction. repeat head ct: 1. extra-axial hemorrhage layering along the right frontotemporal convexity, with appearance most compatible with acute subdural hemorrhage. 2. interval increase in thickness with greatest transverse dimension now 7 mm, increased from 4 mm, without significant change in overall extent. 3. no new hemorrhage. repeat head ct #2: slight interval decrease in the size of the right subdural hemorrhage without evidence of new bleeding. mri c-spine: possible fracture seen on ct not present. no malalignment. no fracture on mri c-spine. brief hospital course: he was admitted to the hospital to the trauma surgical icu for close hemodynamic and neurological monitoring.his hospital course is summarized below by system: neuro: serial head cts showed, at first, growth of his sdh from 4 to 7 mm, however this began to decrease in size as noted on a third head ct. his neurologic exam remained non-focal. he was loaded with dilantin for seizure prophylaxis, dilaudid for pain. because he had stabilized he was then transferred to the floor with q4h neuro checks. he will continue on the dilantin for 7 days and will follow up as an outpatient in clinic for repeat head imaging. cardiovascular: in afib. coumadin held secondary to his subdural hemorrhage. his blood pressure was intermittently high; his home medications were restarted and he has been instructed to follow up with his cardiologist after discharge. pulmonary: no active issues. gastrointestinal/abdomen: was initially npo, diet was advanced for which he was able to tolerate. renal: foley, urine output remained sufficient. his foley was removed and he is voiding without difficulty. hematology: hct trended daily. neurosurgery recommendation to decrease inr to 1.4, but given placement of cardiac stents no vitamin k given. his cardiologist, dr. was contact re: his coumadin being recommended to remain on hold for at least 1 month. per his cardiologist he does not require plavix as his stents were placed in ; he would prefer that he be started on a baby aspirin. neurosurgery was contact and it was recommended to begin the baby asa 7 days from the injury date. this information was provided on his discharge instructions. medications on admission: lisinopril/metoprolol/colchicine/simvastatin/coumadin 10mg daily discharge medications: 1. acetaminophen 325 mg tablet sig: two (2) tablet po q6h (every 6 hours) as needed for pain. 2. lisinopril 10 mg tablet sig: one (1) tablet po bid (2 times a day). 3. metoprolol tartrate 50 mg tablet sig: three (3) tablet po bid (2 times a day). 4. simvastatin 10 mg tablet sig: one (1) tablet po hs (at bedtime). 5. allopurinol 100 mg tablet sig: one (1) tablet po bid (2 times a day). 6. dilantin extended 100 mg capsule sig: three (3) capsule po once a day for 4 days. disp:*12 capsule(s)* refills:*0* 7. hydromorphone 2 mg tablet sig: 1-2 tablets po every 4-6 hours as needed for pain. disp:*40 tablet(s)* refills:*0* 8. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day) as needed for constipation. 9. senna 8.6 mg tablet sig: 1-2 tablets po bid (2 times a day) as needed for constipation. 10. milk of magnesia 400 mg/5 ml suspension sig: thirty (30) ml's po twice a day as needed for constipation. 11. baby aspirin 81 mg tablet, chewable sig: one (1) tablet, chewable po once a day: *do not start until . discharge disposition: home discharge diagnosis: s/p motorcycle crash subdural hematoma c5 facet fracture (subacute) discharge condition: . mental status: clear and coherent. level of consciousness: alert and interactive. activity status: ambulatory - independent. discharge instructions: you were admitted to the hospital following a motorcycle crash where you sustained a bleeding injury to your brain. your injury did not require any operations; your neurolgic status was followed closely and you were given dilantin which is an anti-seizure medications to prevent convulsions or seizures; this medication will continue for a total of 7 days. your coumadin, which is a blood thinner is being recommended to be held for at least 1 month, this has been discussed with your cardiologist. he is recommending a baby aspirin until your coumadin can be restarted. if at anytime in th next month you develop palpitations of feel as if your heart rate is irregular please contact your cardiologist to be seen immediatley. followup instructions: follow up in 4 weeks with dr. , neurosurgery, call for an appointment. you will need a non-contrast head ct for this appointment. follow up with your cardiologist, dr. @ hospital in the next 1-2 weeks re: monitoring while off of your usual blood thinner regimen. procedure: transfusion of other serum diagnoses: coronary atherosclerosis of native coronary artery unspecified essential hypertension atrial fibrillation percutaneous transluminal coronary angioplasty status alcohol abuse, unspecified long-term (current) use of anticoagulants personal history of transient ischemic attack (tia), and cerebral infarction without residual deficits subdural hemorrhage following injury without mention of open intracranial wound, with no loss of consciousness closed fracture of fifth cervical vertebra other noncollision motor vehicle traffic accident injuring motorcyclist
