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: the patient is a 72-year-old gentleman with a past medical history of hypertension, a 50-year smoking history, alcohol abuse, and chronic obstructive pulmonary disease who presented to dr. with a large polyp in the right colon. concise summary of hospital course by issue/system: he was taken to the operating room on for a right colectomy. this operation went smoothly. an ileocecectomy was done with an end-to-side ileotransverse colon anastomosis (hand sewn). there were no operative complications. the patient was kept intubated overnight on the first night due to marginal respiratory effort. he was extubated on postoperative day one. in the afternoon on postoperative day one, he was noted to be tachycardic and agitated. a workup indicated that at that point he had entered delirium tremens. the dictation from this point on will cover his protracted hospital course by systems for simplicity sake. 1. neurologic issues: the patient was started on ativan for his delirium tremens, and this ativan was required for extreme agitation for a number of weeks. he was very slowly tapered off the ativan. at this point, he was maintained on clonidine and as needed haldol for his agitation. he has also been diagnosed with metabolic encephalopathy and has a variable examination; at times only tracking with his eyes but not following commands and at other times attempting to speak and following commands. neurologically, he also had a fall out of bed in early . a full workup was done for that including a head computed tomography and a head and neck magnetic resonance imaging; all of which were negative. a cervical spine collar was removed after orthopaedics approved his studies. 2. cardiovascular issues: from a cardiovascular standpoint, he flipped into atrial fibrillation at the time of the onset of his delirium tremens. he was started on amiodarone and lopressor, and his heart rate was controlled well. he actually converted to a sinus rhythm on . the amiodarone and lopressor were to be continued. 3. respiratory issues: the patient has respiratory failure. he was reintubated after his surgery on the night on postoperative day one. eventually, his family agreed to a tracheostomy which was performed on . currently, the patient is in continuous positive airway pressure mode on a ventilator with pressure support at 15, and positive end-expiratory pressure at 10, with 40% fio2, and his blood gastric on these settings was satisfactory. he is on slow pressure support wean at this time. 4. gastrointestinal issues: from a gastrointestinal standpoint, he underwent a right colectomy. the pathology report showed that his cecal polyp was an adenoma. he was tolerating tube feeds at goal through a percutaneous endoscopic gastrostomy tube which was also placed on . his tube feed rate is 85 cc per hour; which is goal. 5. genitourinary issues: the patient has maintained a normal blood urea nitrogen and creatinine. he has adequate urine output. he had a foley catheter in place which was draining clear yellow urine. he has received lasix on a regular basis to keep him at an even to slightly negative fluid balance. 6. infectious disease issues: from an infectious disease standpoint, the patient is currently on tobramycin and meropenem as coverage for campylobacter and pseudomonas pneumonia. these two antibiotics are infusing through a right antecubital peripherally inserted central catheter line; his only intravenous access, and they should be continued for a full 14-day course (which ends on ). 7. hematologic issues: the patient was being anticoagulated for his atrial fibrillation. he has received coumadin, and his inr is currently 1.6. medications on discharge: (his current medications are) 1. insulin sliding-scale which has not been needed. 2. lansoprazole 30 mg by mouth once per day. 3. amiodarone 400 mg per peg-tube once per day. 4. clonidine 0.4 mg per peg-tube three times per day. 5. lopressor 25 mg per peg-tube twice per day. 6. coumadin 5 mg for the last two days; to be dosed according to inr. 7. haldol as needed. 8. lasix as needed. 9. tobramycin and meropenem intravenously. discharge disposition: at this point, he is deemed appropriate for ventilatory rehabilitation and will be allowed to be transferred when he is accepted at an appropriate institution. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more other enterostomy other endoscopy of small intestine insertion of endotracheal tube other bronchoscopy percutaneous [endoscopic] gastrostomy [peg] arterial catheterization temporary tracheostomy colonoscopy open and other right hemicolectomy alcohol detoxification suture of laceration of stomach diagnoses: alcoholic cirrhosis of liver chronic airway obstruction, not elsewhere classified atrial fibrillation pulmonary collapse acute respiratory failure intestinal infection due to clostridium difficile mechanical complication due to other implant and internal device, not elsewhere classified benign neoplasm of colon acute alcoholic intoxication in alcoholism, continuous
