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: patient recorded as having no known allergies to drugs attending: chief complaint: fever, hypotension, bacteremia major surgical or invasive procedure: endoscopic retrograde cholangiopancreatography (ercp) - no stones or strictures noted history of present illness: 78 f w/ htn, hypercholesterolemia who presented to for elective outpt ercp to evaluate asymptomatic biliary ductal enlargement. she was found to have significantly depressed mental status after her ercp. during the procedure she received a total of midazolam 3 mg and fent 125 mcg. after the procedure she felt nauseous and was also given zofran, then 1 mg ativan because zofran was ineffective. due to her altered mental status, she was sent to ed for further evaluation. there was also questionable mention of possible left facial droop while in the recovery area. also noted to have low grade fever, mild hypotension sbp 90s. . in the ed, 96.7 110 107/64 18 95/ra. ekg was sinus tach. ct head showed no acute changes. neuro thought that the unresponsiveness was a result of a global process( hypoperfusion vs toxic-metabolic) and recommended getting an mri w/ dwi. she also had cta chest which was neg for pe, and ct abd and pelvis w/c which was neg for perforation. . past medical history: 1. hypertension. 2. hyperlipidemia. 3. status post hemigastrectomy for bleeding ulcer in . 4. hx asymptomatic biliary dilation: osh mrcp with reportedly prominent intrahepatic ductal dilatation on the left without a definite mass. social history: lives with husband; active and independent tobacco ppd, long-standing. no significant etoh. family history: both mother and father had stroke physical exam: exam in icu: 100.5 108 96/55 108 98/ra gen: sleepy but easy to arouse chest: ctabl heart: rrr, no m/r/g, nl s1 s2 abd: soft, nt, nd, no hsm extr: no edema neuro: aao x 3, cn ii-xii intact, motor exam showed slight decresed power in r grip, otherwise power normal and equal on both side, no focal sensory deficit, reflexes wnl pertinent results: wbc 23.9 on admission ---> now resolved, wbc 4.2 at discharge cr 0.9 blood cultures : 2 sets positive for e. coli, pan sensitive ct chest/abd/pelvis with contrast impression: 1. no evidence of thoracic aortic aneurysm, perforation, intra-abdominal fluid collections. post-ercp inflammatory stranding and gastroesophageal wall edema as described above. 2. intra- and extra-hepatic biliary dilation with multiple low-attenuation hepatic lesions, some of them represent simple cysts, others are too small to characterize. 3. a focally ectatic abdominal aortic segment prior to the aortic bifurcation measuring 3 cm. 4. multiple enlarged mediastinal lymph nodes may be reactive. follow up on a non-emergent basis is recommended. head mri impression: 1. no evidence of restricted diffusion to suggest presence of acute infarction. 2. moderate white matter flair hyperintensities in the periventricular and subcortical distribution, indicative of small vessel ischemia. ercp findings: esophagus: limited exam of the esophagus was normal other s/p bilroth 1 noted. duodenum: limited exam of the duodenum was normal major papilla: the major papilla was located adjacent to a duodenal diverticulum. cannulation: cannulation of the biliary duct was performed with a sphincterotome using a free-hand technique. biliary tree: non-specific dilatation of the biliary tree was noted. both intra and extra hepatic ducts were dilated. there was no stricturing or filling defects noted in the duct. the distal duct was noted to taper normally. impression: s/p bilroth 1 noted. the major papilla was located adjacent to a duodenal diverticulum. cholangiogram revealed a non-specific dilatation of the biliary tree was noted. both intra and extra hepatic ducts were dilated. there was no stricturing or filling defects noted in the duct. the distal duct was noted to taper normally. brief hospital course: 78 female with hypertension, hypercholesterolemia, h/o asymptomatic dilated bile ducts who was admitted after an elective ercp with altered mental status, low grade fever, brief hypotension sbp 90, found to have gnr sepsis 1) gram-negative rod sepsis: she was empirically covered with broad antimicrobial coverage and given aggressive fluid resuscitation with good response. blood cultures returned with e. coli (pan-sensitive) and abx were then narrowed to ceftriaxone iv. exact mechanism of gnr sepsis is not clear: possibly due to dislodgment of existing ?e. coli in biliary tract vs. transient bacteremia caused by ercp. her surveillance cultures are negative to date and she is clinically feeling very well at the time of discharge. she was discharged on ciprofloxacin and will complete a total 14 day course of antibiotics. 2) altered mental status: likely a combination of sedatives used during ercp and concurrent gnr sepsis. she received a head ct and head mri which showed no evidence of acute event. her mental status rapidly recovered on arrival to the icu. of note, the icu staff did elicit a history of snoring and suggested consideration of an outpatient sleep study. her family denies having ever observed any periods of apnea at home. she is completely back at her mental status baseline at this point. 3) mediastinal lad, unclear significance - her chest ct showed evidence of some mild enlargement of mediastinal lymph nodes, which may be reactive in nature. recommend nonurgent follow-up ct scan as outpatient to re-evaluate in months. 4) diarrhea - she developed new diarrhea on hospital day 4. c difficile was sent, but due to the holiday weekend, the lab will not be running any samples for c diff for an additional two days. suspicion for c diff was at least moderate-to-high, given her new antibiotics so she was given a prescription to start flagyl empirically. she knows to seek medical attention if her symptoms do not abate. 5) htn, benign - her anti-htn were held during her icu stay due to her presentation of sepsis. she has now been restarted back on her outpt regimen. 6) non-specific dilatation of the biliary tree - s/p ercp this admission. no strictures or stones noted. biliary team followed her while in-house. they did feel any further biliary intervention was needed at this time and recommended routine follow-up with her pcp. medications on admission: hydrochlorothiazide 25 mg by mouth once a day toprol xl 100 mg by mouth once a day nifedipine xl 30 mg by mouth once a day asa 325 over the counter discharge medications: 1. ciprofloxacin 500 mg tablet sig: one (1) tablet po q12h (every 12 hours) for 10 days. disp:*20 tablet(s)* refills:*0* 2. flagyl 500 mg tablet sig: one (1) tablet po three times a day for 14 days: may cause nausea; take with food. disp:*42 tablet(s)* refills:*0* 3. toprol xl 100 mg tablet sustained release 24 hr sig: one (1) tablet sustained release 24 hr po once a day: please refrain from taking if you develop

coli septicemia e. coli bacteremia biliary duct dilation of unclear significance secondary: hypertension, benign discharge condition: stable discharge instructions: please contact your physician or return to the er for any new fever, chills, nausea, vomiting, or worsening diarrhea. you are being treated with ciprofloxacin for the e. coli bacteria that was found in your bloodstream. your diarrhea may be a natural side effect from antibiotics or it may be from overgrowth of a gi bacteria called c difficile. you are being treated with flagyl in case this is c difficile. please hold your hydrochlorothiazide until your diarrhea improves. we have not made any other modifications to your usual home medications. followup instructions: please see your pcp . within 1-2 weeks. we are recommending that your pcp consider sleep study and repeat chest ct in several months (nonurgent) to evaluate some nonspecific mild lymph node enlargement md procedure: endoscopic retrograde cholangiopancreatography [ercp] diagnoses: other postoperative infection sepsis other and unspecified hyperlipidemia other specified procedures as the cause of abnormal reaction of patient, or of later complication, without mention of misadventure at time of procedure other specified disorders of biliary tract diarrhea septicemia due to escherichia coli [e. coli] enlargement of lymph nodes
