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: past medical history: 1. atrial fibrillation. 2. chronic obstructive pulmonary disease. 3. small cell lung carcinoma. 4. asd repair. 5. pulmonary hypertension. allergies: no known drug allergies.. medications: 1. paroxetine. 2. sotalol. 3. alprazolam. 4. albuterol. 5. prednisone. 6. lasix, 7. coumadin. 8. protonix. 9. home oxygen. the patient had a ct scan done, which showed no coronary artery disease and ejection fraction of 60%. physical examination: on examination, the patient was afebrile. vital signs were stable. abdomen was firm and distended, tender at the right lower quadrant greater than the left lower quadrant with guarding, rebound, and percussion tenderness. there were no hernias noted. the patient had a white count of 15, hematocrit 36, platelet count 310,000. potassium was 3.6. otherwise, electrolytes were within normal limits. ct showed positive free air, positive cecal sigmoid diverticula. duodenum appeared intact with intraluminal air and positive pelvic free fluid. the patient was placed on levofloxacin and flagyl. the patient was made npo. the patient was started on iv fluids and foley catheter was placed. hospital course: the patient was taken to the operating room on for a perforated viscus, sigmoid diverticulitis, and secondary appendicitis. hartmann's procedure with appendectomy was done with no complications. the patient was transferred to the sicu, intubated for monitoring. on postoperative day #1, the patient was extubated. the patient was afebrile, vital signs were stable. the patient had 100% saturation on two liters nasal cannula. white count was done to 10. hematocrit was 29. platelet count was 305,000. other electrolytes were within normal limits. overnight, on postoperative day #1, the patient had an episode of shortness of breath. the patient was placed on kvo and given lasix. the patient also had a brief run of atrial fibrillation for which she was given lopressor. on postoperative day #3, steroids were to be weaned. lasix was continued. the patient was still on lopressor. white count now was 11.3. the patient was placed on broad-spectrum antibiotics. on postoperative day #5, the patient was still on ampicillin, levofloxacin, and flagyl. the patient was afebrile. vital signs were stable with the same bibasilar crackles. abdomen was soft, nontender, and nondistended. the patient had positive tympany. serosanguinous fluid in ostomy bag, viable appearing pink stoma. white count had increased to 17.6, now down to 13.3. on postoperative day #6, the patient continued to be afebrile, vital signs were stable. the patient was still on ampicillin, levofloxacin, and flagyl. the patient appeared to be opening up, started on po pain medications. the patient's white count was noted to be 18.3. abdominal ct was performed to rule out any leak or abscess. ct was negative. on postoperative day #7, the inr was found to be supratherapeutic at 14.5. vitamin k was given. iv: the patient continued to be afebrile, vital signs were stable. white count now decreased to 12.9. the inr was now down to 1.4. the patient with gas in ostomy. the patient continued to advance with diet, holding the coumadin. antibiotics were discontinued. on postoperative day #8, the patient had no complaints. the patient was afebrile. vital signs were stable. abdomen was soft, nontender, and nondistended. white count was now at 12.8. the patient was felt to be tolerating a good diet and pain was controlled. the patient was ambulating freely. the patient was stable for discharge to home with vna services. condition on discharge: stable. discharge status: the patient was discharged to home with vna. final diagnosis: 1. status post hartmann's procedure. 2. appendectomy. 3. chronic obstructive pulmonary disease. 4. small cell lung carcinoma. 5. pulmonary hypertension. 6. atrial fibrillation. discharge medications: 1. percocet for pain control. 2. prednisone 30 mg q.d. the patient is to be restarted on all previous medications. the patient is to follow up with dr. . , m.d. dictated by: medquist36 procedure: temporary colostomy other appendectomy open and other sigmoidectomy anastomosis to anus diagnoses: chronic airway obstruction, not elsewhere classified atrial fibrillation primary pulmonary hypertension malignant neoplasm of other parts of bronchus or lung diverticulitis of colon (without mention of hemorrhage) abscess of intestine appendicitis, unqualified
