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: no known allergies / adverse drug reactions attending: chief complaint: observed syncope at pcp major surgical or invasive procedure: endotracheal tube placement history of present illness: mr. is a 57-year-old homeless male with hx of polysubstance abuse (cocaine), recent diverticulitis, and seizure disorder presenting from pcp's office with witnessed syncope. as per admission note, pt went to pcp to pick up methadone prescription and felt light-headed with slight left sided chest pain relieved with nitroglycerin. of note, pt denied seizure activity, but has seizure history on dilantin. last seizure a few days ago. . recently found to have diverticulitis, on bactrim and flagyl. ct abdomen/pelvis in ed did not show diverticulitis. . on the floor pt was initially complaining of whole body pains from his fibromyalgia and peripheral neuropathy and was requesting methadone. . around 8pm, pt had a visitor who smelled of marijuana. was walking around floor, but then at 10pm, nurse found the patient unresponsive, code blue was called. pt was satting well, fsg 159, normal bp. subsequently had seizure, o2 sats dropped into 70s, decision made to intubate to protect airway. pt then had another episode of seizure vs. combative behavior. then proceeded to vomit after already being intubated. . on arrival to the micu, the patient was intubated and sedated. required multiple propofol boluses for agitation. also had an episode of maroon vomitus, guaic positive. . ros: could not obtain, patient sedated. past medical history: psychotic disorder

pelvic outlet after administration of intravenous contrast. coronal and sagittal reformats were obtained. comparison: none. findings: ct of the abdomen: there is moderate to severe centrilobular emphysema in the lung bases. a 3-mm pulmonary nodule is noted in the left lower lobe (2:4). the visualized portions of the heart and pericardium are unremarkable. the liver enhances homogenously and there are no focal liver lesions. the gallbladder, pancreas, spleen, and adrenal glands are unremarkable. there is a low-density 16-mm well-circumscribed lesion in the upper pole of the left kidney, most likely representing a simple cyst. the kidneys enhance symmetrically and excrete contrast without evidence of hydronephrosis or stones. the stomach and small bowel are unremarkable. there is no free air or free fluid. abdominal aorta is normal in caliber. ct of the pelvis: though the appendix is not definitely visualized, a candidate structure for the appendix is air-filled and appears normal (2:53). scattered diverticula without evidence of diverticulitis are noted in the sigmoid colon. the remaining portions of the colon are unremarkable. the rectum, urinary bladder, prostate, and seminal vesicles are unremarkable. there is no pelvic free fluid. osseous structures: sacralization of the l5 vertebra is noted on the left. there are no suspicious osseous lytic or blastic lesions. impression: 1. centrilobular emphysema with a 3-mm left lower lobe pulmonary nodule. followup with a dedicated ct of the chest is recommended. 2. no acute intra-abdominal abnormality. 3. diverticulosis without evidence of diverticulitis. . brief hospital course: mr. is a 57-year-old homeless male with history of polysubstance abuse (cocaine), and seizure disorder presenting from pcp's office with witnessed syncope. while on the floor, he was found unresponsive so a code blue was called for possible seizure activity and he was intubated for airway protection. he ultimately left ama. . # seizures: the patient was first found to be unresponsive, then had seizure. at this time, he was intubated for airway protection. has known history of seizure disorder, reported to take dilantin at home. on admission, dilantin level negligible, and was also low with pericode labs. however, a spot eeg was negative for epileptiform activity. also on home benzodiazepines, could be benzo withdrawal. finally, he had a visitor who the nursing staff identified as possible drug user directly before the seizure activity and the patient admitted to using something while in the hospital but did not specify what. urine tox positive for cocaine. . # bloody vomitus: patient with multiple episodes of guaic + maroon vomiting after his seizure. no known liver disease, unclear what drinking history is, but patient is polysubstance abuser. he underwent an egd which found only clean based ulcers and no explanation for the bleeding. h. pylori serologies were sent but were not resulted when he left ama. he was kept on a ppi while in house. after he was extubated, he was complaining of abdominal pain and was preoccupied with his home opiod and benzo doses. it is possible that he was withdrawling from opiods (chronic methadone at home) and had repeated emesis prior to seizure which then caused small tear. . # polysubstance abuse: utox positive for cocaine and methadone (prescribed). once he was extubated and off sedation, he was restarted on his home doses of methadone and clonazepam (after about 5 days off these meds) but he was still agitated and ultimately left ama. also, two drug pipes were found in his belongings and given to the hospital police. . # code: full . transitional issues - please follow up h. pylori serologies and start therapy for gastric ulcers - please reassess his needs for housing and substance abuse counselling medications on admission: clonazepam 1mg tid (last filled ) phenytoin 500mg daily bactrim ds 1tab x 10 days flagyl 500mg
