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 an 85-year-old, caucasian, female patient with history of early alzheimer's dementia and diabetes mellitus type ii, a remote history of breast cancer, but previously otherwise independent who was recently admitted to the neurosurgical service on status post a head trauma with right frontotemporal subarachnoid hemorrhage and cerebral edema. she was discharged on and returned with fevers. the patient was followed by the neurosurgical service and was loaded initially with dilantin for concern of seizures as well as decadron for cerebral edema demonstrated on a head ct. the patient's neurologic status remained relatively stable since her accident, and she was discharged to for rehabilitation on the day of admission. prior to discharge, today, the patient was noted to have a low-grade fever of 100 degrees for which she was started on levofloxacin for possible pneumonia as she failed a recent speech and swallow evaluation in-house and self-discontinued her nasogastric tube with possible aspiration. once she arrived at , the patient was noted to have a fever of 102 or 103 and was sent to back to the emergency department at for reevaluation. in the emergency department, the patient was unable to provide an adequate history but received 1 gram of ceftazidime, 500 mg of flagyl, and two liters of normal saline. past medical history: her past medical history is significant for diabetes mellitus type ii, alzheimer's dementia, breast cancer status post mastectomy, atrial fibrillation. medications: aricept 5 mg p.o. q.h.s., zantac 150 mg p.o. b.i.d., metoprolol 25 mg p.o. b.i.d., levoxyl 112 mcg p.o. q.day, levofloxacin 500 mg p.o. q.day, glyburide 10 mg p.o. b.i.d., lisinopril 10 mg p.o. q.day, subcutaneous heparin, lentis 20 units q.h.s., regular insulin sliding scale, colace 150 mg p.o. b.i.d. allergies: the patient has no known drug allergies. physical examination: vital signs were temperature 97.8, blood pressure 121/59, heart rate 92, respirations 20, saturation 97 percent on two liters. in general, the patient is an elderly woman, awake but appearing slightly agitated, not following commands. heent: pupils are equal, round, and reactive to light and accommodation bilaterally. extraocular movements intact. the oropharynx is clear. she has dry mucous membranes. lung exam reveals shallow breaths bilaterally with crackles in the right upper lobe and right lower lobe. decreased breath sounds were noted in the left lower lobe. her heart had an irregularly irregular rhythm and was tachycardiac. her abdomen was soft, nontender and nondistended. extremities revealed no evidence of edema. neurologic: awake, able to state several words, not following commands, moving all extremities briskly and spontaneously. tight grasps bilaterally. she had upgoing toes bilaterally. laboratory data: white blood cells 15.9, hematocrit 35.9, platelets 382, pt 12.0, ptt 23.8, inr 1.0. sodium 129, potassium 7.8 (hemolyzed), repeat 4.7, chloride 95, bicarbonate 25, bun 33, creatinine 1.0, glucose 258, calcium 9.1, phosphate 2.5, magnesium 2.2. urinalysis revealed ph 1.021, moderate blood, negative nitrites, negative leukocyte esterase, 250 glucose. tsh 13, free t4 0.9, hemoglobin a1c 7.4, phenytoin 4.4. head ct revealed right frontotemporal swelling consistent with contusion, no evidence of blood, no new change compared with a previous ct done on . electrocardiogram revealed atrial fibrillation with a rate of 112. no changes from her baseline. hospital course: fever: the etiology of the patient's fever was considered likely aspiration pneumonia given her history of self- discontinuing her nasogastric tube during her previous hospital stay. the patient was continued on levofloxacin and flagyl throughout her brief hospital stay. she was noted to be afebrile with good oxygen saturations in room air with no subjective complaints of shortness of breath or cough. her lung exam cleared throughout her brief hospital stay. her blood cultures and urine cultures were negative throughout her admission. the patient will receive a 14-day course of both levofloxacin and flagyl for presumed aspiration pneumonia. neurologic: the patient was admitted with a questionable history of altered mental status. the etiology of the patient's mental status changes is likely multifactorial including her cerebral edema and intracranial hemorrhage, infection, hyponatremia on admission, as well as her underlying dementia. the patient's infection was treated as above. her hyponatremia resolved with intravenous hydration. donepezil was considered for alzheimer's dementia. the patient's mental status was considered to be stable throughout her brief hospital stay. the patient was noted to be possibly more dysphagic and dysarthric during this hospital stay and was reevaluated by neurosurgery who felt that these symptoms were unchanged from her previous hospitalization. a repeat head ct was performed on which showed no change in her intracerebral hemorrhage. a neurologist, dr. , was contact prior to the patient's discharge, and his comments on the case are pending at the time of dictation. given that there were no changes noted on the repeat ct, no further workup is being initiated at this time. cardiovascular: the patient was admitted with a history of atrial fibrillation and diffuse st elevations noted on . a decision was made not to anticoagulate the patient given her recent subarachnoid hemorrhage. the patient had stable tachycardia and was rate controlled with a beta blocker. her rate improved once she received a percutaneous endoscopic gastrostomy tube, and her beta blocker could be administered. the patient had an echocardiogram performed on which was significant for an ejection fraction over 55 percent, borderline pulmonary artery hypertension, and no evidence of pericardial effusion. she was noted to be normotensive and hemodynamically stable on her outpatient doses of an ace inhibitor and beta blocker. given the concern for myocardial infarction, with her st elevations on electrocardiogram, the patient was ruled out for myocardial infarction with bicardiac enzymes. fluids, electrolytes and nutrition: the patient was noted to have significant dysphagia. on admission, she was evaluated by speech and swallow. their study was significant for overt signs and symptoms of aspiration with all consistencies assessed. the patient's cognitive deficits were considered likely contributors to her decreased bolus manipulation and swallow initiation. it was therefore recommended that the patient receive a percutaneous endoscopic gastrostomy tube, which she did on . she was restarted on tube feeds which were eventually titrated up to goal. the patient tolerated these tube feeds. it is anticipated that this percutaneous endoscopic gastrostomy tube will not significantly improve the patient's risk of aspiration, but will allow her to receive adequate nutrition. the patient was also admitted with hyponatremia which resolved with intravenous fluids. hypothyroidism: the patient was noted to have a tsh of 13 on admission. her levothyroxine dose was increased to 125 mcg q.day. she will need to have a repeat tsh and free t4 checked approximately one month after this medication change. diabetes: the patient was previously evaluated by the clinic. her insulin regimen was continued per their recommendation, and she was noted to have well controlled sugars throughout this admission. problem #7: gastrointestinal: as noted above, the patient received a percutaneous endoscopic gastrostomy by the gastroenterology consultation service on . during the esophagogastroduodenoscopy, she was noted to have mild gastritis and erosions, and her h2 blocker was switched to a proton pump inhibitor. condition on discharge: good. discharge status: the patient is discharged to a rehabilitation facility where she will continue all medications as prescribed. discharge diagnosis: 1. pneumonia, unspecified. 2. hypertension. 3. atrial fibrillation. 4. subarachnoid hemorrhage. 5. hypothyroidism. 6. diabetes mellitus type ii. discharge medications: 1. levothyroxine 125 mcg p.o. q.day. 2. lisinopril 10 mg p.o. q.day. 3. metoprolol 25 mg p.o. b.i.d. 4.
