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 a 76-year-old woman with past medical history significant for aortic stenosis and patent foramen ovale status post atrial septal defect repair and aortic valve replacement in , that presents to the emergency room with complaint of abdominal pain and report of free intraperitoneal air on x-ray at her rehabilitation facility, . briefly, this is a 76-year-old female who has multiple medical problems as described above, including hypercholesterolemia, peripheral vascular disease, chronic obstructive pulmonary disease, and known lung cancer, that was recently discharged 2 days prior to rehabilitation facility after a lengthy hospital course in which she underwent an aortic valve replacement and an atrial septal defect closure. she was taken after this point to the surgical intensive care unit for monitoring, however, had developed respiratory distress that required intubation. she required tracheostomy, as well, during this prior stay and was noted to be doing well at the rehabilitation facility in terms of her respiratory status up to this point. also of note, she also received before her prior discharge a percutaneous endoscopic gastrostomy tube placed by the general surgery service. this was done on , seven days before discharge to the rehabilitation facility. of note, the patient continued to have free intra-abdominal air during her stay in the intensive care unit before her discharge. however, her abdominal pain resolved, and she was able to resume her tube feeds per recommendation of the general surgery service. upon discharge she was sent to the rehabilitation facility, where she was noted to be progressing well until her 3rd day when she noted abdominal pain. at this time a kidney/ureter/bladder x-ray was performed that revealed significant right- and left-sided intraperitoneal free air. the patient was then sent back to the for further evaluation and treatment. past medical history: hypercholesterolemia, peripheral vascular disease, chronic obstructive pulmonary disease, right iliac artery disease, lung cancer, malignant pericardial and pleural effusions, pacemaker in situ, left carotid endarterectomy, hysterectomy, pericardial window, tonsillectomy, mitral regurgitation, aortic stenosis, patent foramen ovale, and coronary artery disease. medications: amiodarone, lipitor, warfarin, furosemide, lansoprazole, digoxin, aspirin, fluconazole, and vancomycin. vancomycin was for a methicillin-resistant staphylococcus aureus that was growing out of her sputum prior to her previous discharge. physical examination on admission: temperature 97.8 f, heart rate 81 in sinus rhythm, blood pressure 148/71, respiratory rate 18, 100 % on room air. she is generally comfortably appearing and is sitting up in bed at this time. her tracheostomy is noted to be in place without drainage or erythema around the site. her lungs are clear to auscultation bilaterally with some coarse breath sounds reported. her incision is noted to be well healed with steri-strips beginning to slough off. there is no drainage or erythema around the sternal wound. her heart is in regular rate and rhythm. without murmurs, rubs, or gallops at this time. her abdomen is noted to be slightly distended with slightly hypoactive bowel sounds. soft. minimally tender throughout. no signs of rebound or guarding at this time. her extremities are warm and well perfused. distal pulses are 2+ with no clubbing, cyanosis, or edema. hospital course: thus, at this time the patient was admitted to the for further evaluation and treatment. this 75-year-old female recently discharged with an aortic valve replacement and atrial septal defect repair was brought back into the hospital for further evaluation of persistent intraperitoneal free air status post percutaneous endoscopic gastrostomy tube placement on , nine days prior to this at readmission. the question at this point was whether there was an active leak from the percutaneous endoscopic gastrostomy tube. a cat scan was performed at this time that revealed no extravasation, though this did not satisfy our curiosity in regard to the possibility of anterior leak of the percutaneous endoscopic gastrostomy tube. the patient was noted to be stable, was afebrile, with a leukocyte count that was within normal limits and unchanged from 5 days previously. the plan at this time was to do a water-soluble contrast study through this peg tube and to assess the patient in the prone position for possible anterior leak. on hospital day #3 the patient began to feel better, with less abdominal pain and less distention at this time. patient continued to remain afebrile and to remain hemodynamically stable. there were no sudden rises in the leukocyte count, as well. the rest of her laboratories was within normal limits. we placed her peg tube to gravity at this time with the plan to have a prone study performed the following day, and to continue to hold tube feeds at this time. in addition, clostridium difficile toxin was sent off which came back negative. it was also notable that the patient was passing gas and having bowel movements at this time. on hospital day #4 the patient continued to progress well and was noted to be comfortable and did receive 1 unit of packed red blood cells at this time for a hematocrit of 25.6, noted to be down from 28 the previous day. the patient then had a follow up portable abdominal x-ray on tuesday, , hospital day #5, that continued to show persistent large amount of free intraperitoneal air. there was retained contrast present in the colon, but there was, again, no sign of any sort of leak at this time. thus, throughout the hospital course there was, at no point, that we could locate a definitive leak of contrast due to the percutaneous endoscopic gastrostomy tube. it was determined that the patient could have her tube feeds resumed. on hospital day #5 these tube feeds were resumed, indeed, and the patient tolerated them well and was slowly increased to her goal rate of 50 ml per hour of probalance with fiber. also at this time, the patient received a picc line on the right side that was placed under interventional radiology due to her presence of a permanent pacemaker on the left side. the patient also had a study of the venous system in the left upper extremity that revealed thrombosis of the left subclavian vein. this venous catheter was removed after the procedure and the port remained in place in the left antebrachial area. then, on hospital day #6, the patient was evaluated again and had been continued on her tube feeds at this time. she was noted to be tolerating these well and was noticeably less distended on examination. she was spending significant amounts of time in her chair and was tolerating a tracheostomy mask at this time with continued plan for her to rest at night on the ventilator. on hospital day #6, it was determined the patient was fit for discharge to rehabilitation facility on continued tube feeds. the patient was to receive 1 more week of vancomycin for positive blood culture and yeast in sputum. the patient was to continue on tracheostomy mask during the day as needed and to be placed on the ventilator as needed at night so that she could rest. fluconazole was not given necessary upon discharge. erving any increasing pains, fevers, chills, nausea, vomiting, shortness of breath, chest pain, redness or drainage about the wounds, or if there are any questions or concerns or signs of any events there untoward. patient to continue on continuous positive airway pressure and pressure support for 12-14 hours a day goal and to receive assist control at night for rest. patient to have international normalized ratio checked daily with goal of 2.0-2.5. patient to receive tube feedings of probalance full strength at 50 ml per hour with checks every 4 hours for residuals, and tube feeds to be held for any residual greater than 100 ml. patient to have an appointment with dr. scheduled upon discharge from rehabilitation facility. discharge diagnoses: 1. intraperitoneal free air in abdomen. 2.
