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: submental floor of mouth abscess. major surgical or invasive procedure: : incision and drainage of deep neck and floor of mouth abscess. history of present illness: this is an 82 year-old russian male who presented to the ed on , the date of admission, with the chief complaint of fever to 100.1, acute mental status change (from alert and oriented to self to minimal orientation) and who fell without loss of consciousness on . he was placed in a cervical collar and admitted to the micu on . after c-spine clearance, it was noticed that the patient had significant left facial swelling that had increased in extent quite rapidly. the patient appeared agitated, but given his baseline mental status, it was difficult to determine if he was in pain. there was no purulent drainage from the parotid duct. his wbc was 13.0 initially and had risen to 21.5 when ent was asked to evaluate the patient's neck swelling. he was placed on vancomycin, cefepime and flagyl on for broad spectrum coverage of a possible lll pna/infiltrate and for this likely neck infection. on initial exam, he had signficiant left facial swelling anterior to the tragus and extending inferiorly to the region of the masseter and submandibular gland, without submental involvement. he had slight nonblanching erythema of the overlying skin, without fluctuance. a ct neck was performed on showing an extensive multiloculated rim-enhancing fluid collection with foci of gas extending inferiorly from the left parotid gland and parapharyngeal space into the sublingual and bilateral submandubular space. the findings were highly suspicious for abscess. inflammatory changes extended inferiorly to the level of the epiglottis with obliteration of the left vallecula and with narrowing of the supraglottic airway. the patient went to the or on for incision and drainage of a deep neck and floor of mouth abscess. past medical history: parkinson's disease dementia, recurrent right inguinal hernia s/p repair, left orchiectomy in the distant past, "due to infection" in complicating prostectomy, urosepsis in , colonic polyps, depression, glaucoma, htn social history: lives with wife. moved to the us in and was a former engineer that worked with small doses of 'chemicals' but he is unaware of toxicity. denies alcohol use. denies smoking use. no illicit substance use. family history: non-contributory. physical exam: upon discharge: vitals: t - 96.5, hr - 61, bp - 125/72, r - 20, o2 sat - 100% on ra neck: incision clean/dry/intact, no mass, no fluctulance cvs: rrr, s1, s2, no murmurs/rubs/gallops resp: coarse breath sounds b/l gi: bowel sounds present, soft ext: contracted pertinent

represent early left lower lobe pneumonia. ct c-spine: impression: no sign of fracture or abnormal alignment. multiple-level djd with narrowing of vertebral foramen and neural foramen. ct neck : impression: 1. extensive multiloculated rim-enhancing fluid collection with foci of gas extending inferiorly from the left parotid gland and parapharyngeal space into the sublingual and bilateral submandubular space. these findings are highly suspicious for abscess. inflammatory changes extend inferiorly to the level of the epiglottis with obliteration of the left vallecula and narrowing of the supraglottic airway. 2. severe attenuation of the superior aspect of the jugular vein with several millimeters of non-enhancement suspicious for short segment thrombosis. reconstitution of the jugular vein noted at the jugular foramen/skull base. 3. moderate bilateral pleural effusions. brief hospital course: 1) parotid/submandibular abscess: s/p debridement by ent who is managing dressing changes. pt was treated on course of flagyl 500 mg q8h, cefepime 2g iv daily, vanco 1250 mg q12h. as pt still spiked a fever on these abx on , id c/s called and followed patient. his cefepine dose was increased to 2g iv q12. polymicrobial growth from abscess cultures and blood cultures had no growth. dental followed the patient as per recs of ent, however dental needed panorex to recommend teeth extraction but were unable to do it because patient cannot stand. omfs saw pt on and did not feel his teeth that caused the abscess. he needs to follow-up at with dental as an outpatient. he was discharged with 1 week of flagyl for a second brief elevation in his wbc count near the end of his hospitalization which resolved with flagyl. . 2) nutrition: he had a speech and swallow evaluation. he was determined to be at risk for aspiration, but the family decided he would not get a feeding tube and they understood the aspiration risk. all medications except sublingual sinemet and exelon were held due to the difficutly swallowing. by the end of the hospitalization the patient was able to tolerate soft solids. please reconsider starting patient's other medications when he is able to safely swallow them. . 3)parkinson's disease/dementia: the patient's symptoms acutely worsened in the setting of infection and baseline dementia. per outpatient neurologist, we avoided anti psychotics. we increased his dose of sinemet to two tabs 3 times per day. we continued his exelon in liquid form. the patient's rigidity and his demenia/delerium improved during the hospitalization. please avoid any psychoactive medications. . 4) respiratory failure: mr. had respiratory failure and needed to be intubated following his abscess drainage. the failure was likely secondary to likely airway compromise from surgical edema. he was intubated for several days. the swelling improved and he was extubated and maintained good oxygen saturation on room air. . 5) end of life/goals of care: mr. family is very involved. they chose to defer peg tube placement at this time, understanding the risk of aspiration. medications on admission: xalatan 0.005 % 1 gtt ou qhs alphagan p 0.1 % 1gtt ou
