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: history of present illness: this is a 63-year-old man with a history of hypertension, benign prostatic hypertrophy, and a recent history of upper respiratory infection type symptoms x1 week, who presents to the emergency department complaining of increased ear pain and drainage x1 week. he was found by his daughter this afternoon unresponsive and brought to the emergency department for workup of mental status changes. they have been seen by his primary care physician earlier in the week, and was started on ear drops for otitis externa. he had been working at his job as late as the wednesday before admission. history was received all via the family. past medical history: 1. hypertension. 2. benign prostatic hypertrophy. 3. sinusitis. social history: wife died from colon cancer one year ago. lives with son. former . medications: 1. claritin. 2. ear drops. 3. flonase. allergies: no known drug allergies. physical examination: vital signs: temperature 104, heart rate 120, blood pressure 190/100, oxygen saturation 96% on room air. the patient's physical examination in the emergency department was significant for a stuporous unresponsive state for which he required intubation. there were no other pertinent findings on physical examination. the patient had bilateral external auditory canal purulent drainage with blood behind the right tympanic membrane. pertinent laboratories and diagnostic tests on admission: the laboratories revealed a white count of 14.2 with 83% neutrophils, and 5% bands. the rest of his complete blood count, lfts, and chemistries were normal. the patient's coagulation profile was normal. the patient had a lumbar puncture which drained purulent csf and had an opening pressure greater than 55 mm of water. the patient had an electrocardiogram which revealed sinus tachycardia with a q wave in iii, normal axis, and no st-t wave changes. the patient had a chest x-ray which was negative. patient had a head ct scan which revealed a left maxillary sinusitis. assessment: this 63-year-old man with bacterial meningitis. hospital course: the patient was treated initially with ceftriaxone, vancomycin, ampicillin, and dexamethasone for his presumed bacterial meningitis. the differential diagnosis included strep pneumonia, hemophilus influenza b and neisseria. csf studies revealed a white count of 7,230, protein of 325, glucose of 1, and red blood cells of . csf cultures revealed gram-positive cocci in pairs. blood cultures x4 were positive for streptococcus pneumoniae with sensitivity testing revealing pan-sensitivity including to penicillin. urine culture was negative. after the sensitivities were obtained, the patient was switched on iv therapy to penicillin-g, with no further need for ceftriaxone, vancomycin, or ampicillin. the dexamethasone was continued for three days. although he required intubation for airway protection given his altered mental status, the patient was extubated shortly after admission. he was then able to tolerate dietary support and po intake. his electrolytes remained normal throughout his hospital stay requiring very little repletion. the patient's white count reached the maximum of 21.2, but decreased gradually throughout his hospital stay. he was continued on his outpatient medications. the patient's mental status continued to improve throughout his hospital stay. discharge status: to rehabilitation facility. discharge condition: good. discharge medications: 1. the patient is to continue all of his outpatient medications. 2. the patient will continue to receive penicillin-g 4 grams iv q4h for a total of two weeks. for this reason, a picc line will be inserted into the patient prior to discharge, and will be removed when the full antibiotic course is completed. followup: the patient is to followup with his primary care physician as needed. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified spinal tap incision of lung insertion of endotracheal tube diagnoses: unspecified essential hypertension pulmonary collapse pneumococcal septicemia [streptococcus pneumoniae septicemia] other alteration of consciousness chronic maxillary sinusitis meningitis due to unspecified bacterium infective otitis externa, unspecified
