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 an 80 year-old gentleman who presented with bright red blood per rectum and hematemesis. the patient was in his usual state of health until two days prior to admission a which time he had several episodes of bright red blood per rectum and one episode of hematemesis on the day of admission. of note, bright red blood per rectum was increased on the day of admission. the patient also states that in his emesis he had noted coffee ground like material. he also complained of lightheadedness and weakness on the morning of presentation. the patient came to the emergency department where he was found to have a hematocrit of 22 from a baseline of 37. nasogastric lavage showed coffee ground, which cleared with 500 cc of lavage. initially the patient's blood pressure was systolic in the 90s, which improved with intravenous fluids. he was also transfused with 2 units of packed red blood cells and started on octreotide. past medical history: 1. chronic lymphocytic leukemia diagnosed in . the patient has opted for observation rather then treatment. his baseline white blood cell count is approximately 2200. 2. history of basal cell carcinoma. 3. status post transurethral resection of the prostate in for benign prostatic hypertrophy. 4. left inguinal hernia status post herniorrhaphy. 5. history of transient ischemic attack in . 6. hypertension. allergies: bactrim. medications: 1. lisinopril/hydrochlorothiazide 20/12.5 mg. 2. aspirin 325 mg q day. social history: the patient is a retired auto mechanic. smoked tobacco, but quit 25 years ago. he drinks one to two alcoholic drinks per week. family history: mother passed away of stomach problems, though the patient does not know what specific problems. review of systems: the patient denies any previous nausea and vomiting. denies any fevers or chills. denies abdominal pain at any time. physical examination on admission: vital signs temperature 97.4. blood pressure initially 96/34 and increased to 125/52 after 2 liters of intravenous fluid. heart rate 102, which decreased to 90. respiratory rate 18. o2 sat 96% on room air. in general, the patient was appearing pale and in no acute distress. alert and oriented. heent examination significant for dry mucous membranes with a clear oropharynx. pupils are equal, round and reactive to light. sclera anicteric with pale conjunctiva. neck is supple. chest examination shows decreased breath sounds throughout with an increased i to e ratio. cardiovascular examination shows a regular rate with no murmurs, rubs or gallops. abdomen is soft, mildly distended with no bowel sounds. abdomen is nontender. liver was 3 cm above the costal margin. extremities showed no edema. distal extremities are cold to the touch with faint peripheral pulses. neurologically the patient is alert and oriented times four and moves all four extremities. cranial nerves are all intact. rectal examination shows guaiac positive stool with melena in the vault. laboratories on admission: cbc significant for a white blood cell count of 73 with 20% neutrophils, 0% bands and 79% lymphocytes. hematocrit is 23 from a baseline of 37 with an mcv of 84. platelets are 245. coagulation studies show an inr of 1.2. chem 7 53 and 48, bicarbonate of 19 and bun of 117 and a creatinine of 1.9 increased from a baseline of 1.2 to 1.3. electrocardiogram showed sinus arrhythmia with a rate of 96 beats per minute. t wave and st changes unchanged from . hospital course: 1. gastrointestinal bleed: the patient was initially admitted to the intensive care unit for monitoring with significant gastrointestinal bleed. the patient was transfused 4 units of packed red blood cells. gastrointestinal was consulted and an esophagogastroduodenoscopy was done, which initially showed dieulafoy lesion in the body of the stomach, which was treated with thermotherapy to stop the bleeding. subsequently the patient had a repeat esophagogastroduodenoscopy, which showed pinpoint areas of bleeding around the lesion site. repeat cauterization was not successful and so no further therapy was done. the patient's hematocrit was monitored and it remained relatively stable for the rest of the hospital course. the patient did not have any further bright red blood per rectum or hematemesis. his diet was advanced and he tolerated the diet without any nausea or vomiting. he was also hemodynamically stable for the duration of the hospital admission after the repeat esophagogastroduodenoscopy. the patient was placed on proton pump inhibitor with protonix 40 mg b.i.d. and he was continued on that through discharge. as there was also bright red blood per rectum the patient would need a colonoscopy as an outpatient and this was set up by the gastrointestinal service for approximately one month after discharge. 2. coronary artery disease: while in the intensive care unit the patient was on telemetry and he had one 12 beat run of nonsustained ventricular tachycardia. he did not have any repeat nsvt episodes. he was ruled out for a myocardial infarction. his aspirin was held due to the gastrointestinal bleeding. his antihypertensive medication was also held due to hemodynamic instability from gastrointestinal bleeding. after the patient's hematocrit stabilized his blood pressure remained very well controlled and therefore he was not started on his antihypertensive during the hospitalization. he should be restarted on this medication after he follows up with his primary care physician approximately one week after discharge if needed. the patient should have a cardiology follow up as an outpatient for possible further workup of his episode of nsvt. the patient also was subsequently noted to have an irregular heart rate and the electrocardiogram showed atrial ectopy, however, his rate was controlled and no further therapy was done at this time. 3. oncology: the patient has a history of cll with a baseline white blood cell count approximately 2200. on admission his white blood cell count was significantly increased to greater then 70,000 with a lymphocytic predominance. throughout the rest of the hospital admission the white blood cell count decreased and returned back to his normal baseline prior to discharge. 4. acute renal failure: patient was in mild acute renal failure on admission. this was likely due to a hypovolemic state from significant gastrointestinal bleeding he had. after transfusion repletion of fluids the patient's creatinine returned back to baseline. 5. history of transient ischemic attack: the patient had been on an aspirin for his history of transient ischemic attack, however, given his gastrointestinal bleed he should not take any aspirin or any other non-steroidal anti-inflammatory drugs for the near future. 6. code status: the patient is full code on admission and at discharge. discharge status: the patient is to be discharged home. discharge diagnoses: 1. upper gastrointestinal bleed with dieulafoy lesion in the stomach. 2. chronic lymphocytic leukemia. 3. acute renal failure. 4. nonsustained ventricular tachycardia. discharge condition: the patient is in good condition. he is afebrile and hemodynamically stable and tolerating po with a stable hematocrit. discharge medications: protonix 40 mg b.i.d. discharge instructions and follow up plans: the patient was instructed to refrain from taking any aspirin or non-steroidal anti-inflammatory drugs. he is also told to hold his antihypertensive until his blood pressure was rechecked by his primary care physician whom he should follow up with in approximately one week. the patient is also set up for an outpatient colonoscopy with gi on . he is asked to call his primary care physician or return to the hospital immediately if he feels persistently lightheaded, dizzy or weak. , m.d. dictated by: medquist36 procedure: endoscopic control of gastric or duodenal bleeding endoscopic
