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: struck in the back of the head major surgical or invasive procedure: :left temporal craniotomy and evacuation of epidural hematoma. history of present illness: 21 year-old man who was witnessed to be struck in the back of the head by an unidentified object in earlier this morning (roughly 1.5 hours ago). patient then fell backward, striking the occiput. ems was called and he was found supine on the ground. ems trip sheet not available and initial examination unclear. past medical history: unknown at present social history: only child / mother and stepfather from / he is a senior . family history: unknown physical exam: physical exam: o: t: f bp: 105/75 hr: 80 r: 14 o2sats: 100% gen: lying in bed with eyes closed. heent: scalp laceration over occiput oozing blood. neck: in hard collar. lungs: cta bilaterally. cardiac: rrr. s1/s2. abd: soft, nt, bs+ extrem: warm and well-perfused. neuro: mental status (off sedation): does not open eyes to command or follow commands. cranial nerves: i: not tested ii: pupils equally round and reactive to light, 5 to 3mm bilaterally. iii, iv, vi: gaze is dysconjugate with slight lateral deviation of the left eye. unable to perform doll's eyes maneuver due to hard collar. v, vii: grimaces in response to supraorbital stimulation. no overt facial droop (though somewhat obscured by ett). motor: withdraws to noxious stimulation throughout. no abnormal movements noted. sensation: as above, withdraws to noxious stimulation throughout. reflexes: b t br pa ac right 1 1 1 1 1 left 1 1 1 1 1 toes mute bilaterally pertinent results: cardiology report ecg study date of 4:07:40 am sinus bradycardia. modest early repolarization changes. no previous tracing available for comparison. ct c-spine w/o contrast sat 5:29 am impression: 1. no fracture identified. 2. relative narrowing of the c6-7 spinous processes interspace with relative widening of the anterior intervertebral disc space at this level may be positional. ct head w/o contrast 3:12 am 1. non-displaced fracture of the squamous part of the left temporal bone. 2. left extra-axial collection, likely epidural hematoma. 3. right extra-axial blood, most likely subarachnoid hemorrhage and/or subdural hematoma. chest (portable ap) 3:37 am 1. et tube terminating 6 cm above the carina. 2. the ng tube is high, terminating at the level of the diaphragm and should be advanced. this was discussed with dr. at 5:05am on . 3. clear lungs. ct head w/o contrast 8:05 am 1. marked increase in size of the left epidural hematoma overlying the left temporal lobe, with new uncal herniation and increase in rightward subfalcine herniation. 2. no interval change in additional foci of extra-axial hematoma overlying the right temporal lobe, likely also reflecting areas of epidural hematoma. ct l-spine w/o contrast 8:06 am impression: no fracture or malalignment. ct t-spine w/o contrast 8:06 am no evidence of fracture or malalignment. ct head w/o contrast 6:04 pm 1. no interval change in residual left temporal epidural hematoma, status post partial evacuation compared to examination from six hours prior. 2. no overt interval change of multiple small foci of extra-axial hematomas overlying the right frontal lobe which may also reflect smaller areas of epidural hematoma. 3. persistent mild shift of normally midline structures to the right of 3 mm. ct head w/o contrast 8:34 am 1. status post left temporal craniotomy with stable appearance of the bilateral extra-axial temporal hemorrhage and the right frontal extra-axial hemorrhage. 2. interval improvement in the left uncal herniation. unchanged subfalcine herniation. brief hospital course: pt was admitted through the emergency room after tbi on in the early morning. repeat ct scan of the brain showed interval increase in the size of edh. he was taken to the or emergently for evacuation. his operative and post-operative periods were without event. he was returned to the icu where he was later extubated. he was placed on dilantin on arrival for sz prophylaxis. his neuro status was monitroed closely. he was placed on one to one observation for safety as he was found to be impulsive and combative after exutbation. serial ct scans demonstrated postoperative changes with good decompression of edh. he was transferred to step down on . he was advanced in his diet and activity and seen and evaluated by pt and ot and recommended for acute rehab. his incision was clean and dry. he continued on pain medication for incisional pain/headache. diet was advanced. medications on admission: unknown discharge medications: 1. levetiracetam 1,000 mg tablet sig: one (1) tablet po bid (2 times a day). 2. famotidine 20 mg tablet sig: one (1) tablet po bid (2 times a day). 3. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po q 4-6 hours prn () as needed for pain. discharge disposition: extended care facility: - discharge diagnosis: left temporal edh. discharge condition: stable discharge instructions: general instructions ?????? have your incision checked daily for signs of infection. ?????? take your pain medicine as prescribed. ?????? exercise should be limited to walking; no lifting, straining, or excessive bending. ?????? you may wash your hair only after staples have been removed. ?????? you may shower before this time using a shower cap to cover your head. ?????? increase your intake of fluids and fiber, as narcotic pain medicine can cause constipation. we generally recommend taking an over the counter stool softener, such as docusate (colace) while taking narcotic pain medication. ?????? unless directed by your doctor, do not take any anti-inflammatory medicines such as motrin, aspirin, advil, and ibuprofen for 1 month ?????? you have been prescribed keppra(levetiracetam), for anti-seizure medicine, you will not require blood work monitoring. ?????? clearance to drive and return to work will be addressed at your post-operative office visit. ?????? make sure to continue to use your incentive spirometer. call your surgeon immediately if you experience any of the following ?????? new onset of tremors or seizures. ?????? any confusion or change in mental status. ?????? any numbness, tingling, weakness in your extremities. ?????? pain or headache that is continually increasing, or not relieved by pain medication. ?????? any signs of infection at the wound site: redness, swelling, tenderness, or drainage. ?????? fever greater than or equal to 101?????? f. followup instructions: follow-up appointment instructions ??????please return to the office in days, from your date of surgery, for removal of your staples or they can be removed at the . ??????please call ( to schedule an appointment with dr. , to be seen in 4 weeks. ??????you will need a ct scan of the brain without contrast. ??????you will not need an mri of the brain. procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube other craniotomy diagnoses: open wound of scalp, without mention of complication assault by striking by blunt or thrown object open wound of lip, without mention of complication closed fracture of base of skull with subarachnoid, subdural, and extradural hemorrhage, with loss of consciousness of unspecified duration external ophthalmoplegia
