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: hepatitis b and hcc, needing liver transplant major surgical or invasive procedure: liver transplant history of present illness: is a 54-year-old male with a history of hepatitis b diagnosed in who is presenting today for a possible liver transplant. on a screening ct scan from , five years from his initial diagnosis, he was found to have two small arterial enhancing foci within the liver concerning for hepatocellular carcinoma. on , he underwent a ct-guided biopsy confirming the diagnosis of hepatocellular carcinoma and radiofrequency ablation of one of these lesions. only one lesion was ablated because the other lesion was located too close to the colon. subsequently, he underwent transarterial chemoembolization of the second lesion in . his most recent ct scan from on reveals cirrhosis and treated hcc with no new lesions. also noted are chronic venous thrombosis and portal hypertension. the patient reports no priorabdominal surgeries. he has occasional discomfort around the "liver area" and his right flank that is transient and brief. he has been feeling well recently, denies fever, chills, nausea, vomiting, diarrhea or any other gi complaints. bowel function normal and has a good appetite. he states he has intermittent abdominal pain and points to his right back area as the source of pain. he denies chest pain, shortness of breath, edema. past medical history: 1. hepatitis b 2. cirrhosis 3. 3 hepatoma lesions: tace x2 and rfa x1 hepatoma lesion 4. esophageal varices with history of hemorrhage 5. portal hypertension 6. splenomegaly 7. thrombocytopenia, presumably secondary to splenic sequestration. 8. splenic mesenteric vein thrombosis . psh: taca and rfa as described above, otherwise no surgery social history: home: lives with his wife, 21 yo son, and mother occupation: employed as a database administrator etoh: denies drugs: denies tobacco: denies family history: 2 brothers with hepatitis physical exam: on admission: vs: 96.8, 79, 105/61, 18, 97% ra, 75.4 kg general: a&ox3, nad, well nourished, no jaundice neuro: a+ox3, no asterixis, cn ii-xii grossly intact heent: sclerae anicteric. pupils equal, round, and reactive to light. extraocular movements are intact. no oral lesions. mucous membranes moist. oropharynx clear without exudate. neck supple. lymph nodes: no cervical, supraclavicular, occipital, axillary, or inguinal lymphadenopathy. heart: regular rate and rhythm, s1, s2. no murmurs, gallops, or rubs. lungs: clear to auscultation and percussion bilaterally. abd: + bs, soft, non-tender, non-distended, no splenomegaly appreciated, no scars noted, no palpable hepatomegaly, palpable ascites or other masses. extr: warm and well perfused, no peripheral edema, clubbing, or cyanosis. skin: warm and dry, anicteric pertinent results: ctap : 1. cirrhosis and treated hcc. no new lesions. 2. chronic venous thrombosis and portal hypertension. 3. resolved colitis. liver duplex u/s : 1. patent hepatic vasculature; however, the arterial waveforms are abnormal, demonstrating high resistance flow. short-term followup ultrasound is suggested. 2. hyperechoic lesion seen in segment v of the liver, the appearance of which is suggestive of a hemangioma. no biliary dilatation and no collections identified. liver duplex u/s : improved arterial waveforms in the hepatic arteries demonstrating appropriate diastolic flow in the main and right vessels. the left hepatic artery is patent but difficult to visualize due to technical factors. appropriate flow is seen in the portal veins and the hepatic veins. scant trace fluid in the perihepatic spce and small right pleural effusion. cta a/p : 1. the patient is status post recent liver transplant on . an infrarenal aortic graft anastomosed to proper hepatic artery is patent. the portal vein, left and right hepatic arteries are patent. there is no evidence of intrahepatic biliary ductal dilatation. mild periportal edema is noted. 2. peripheral liver hypodesnities that may be post surgical trauma or infarcts. close followup suggested. 3. moderate bilateral pleural effusions with associated atelectasis. brief hospital course: mr. was admitted to the transplant surgery service and underwent an orthotopic deceased donor liver transplant (piggyback), portal vein to portal vein anastomosis, infrarenal conduit from the aorta to the hepatic artery at the confluence of the common hepatic artery and gastroduodenal artery using donor iliac artery graft, common bile duct to common bile duct anastomosis with no t-tube. for full details, please see the dedicated operative report. after his liver transplant, he was taken to the sicu and remained intubated overnight. he remained hemodynamically stable throughout the operation and in the sicu and was quickly weaned to extubate. prior to arriving in the icu, he received 12 units prbcs, 13 units ffp, 4 platelets, and 4 cryoprecipitate. for low plateletes he was transfused 2 further platelets, and for a borderline low hct he was transfused one additional unit prbcs. he was placed on the non-bleeding pathway per the liver transplant pathway. he was transferred out of the unit on pod 1 to the regular floor. the rest of his hospital stay is summarized below by system: neuro: pain was never a prominent complaint and was well controlled on narcotics with a relatively low pain med requirement. cv: remained cv stable throughout his stay. after the initial peri- and post-operative period, he required no further transfusions. pulm: he was extubated on pod 1 and weaned off of oxygen until he was on room air. gi: liver duplex on some abnormal arterial waveforms and so the liver duplex was repeated on pod 2, which showed improvement. a cta of the a/p showed patent vasculature. although he initially had elevated transaminases, this improved with time and his bilirubin and synthetic function improved until discharge. gu: good urine output throughout case and in post-operative period. his foley was removed on pod 3 and he voided without issue. heme: transfusions as listed above. no major issues id: he was placed on antibiotic prophylaxis as per protocol (bactrim/valganciclovir, fluconazole). he was restarted on his entacavir and was given hbig in the or and then daily for five days. on pod 1 he received units for a + hbag, but then got 5000 as his hbab was >500 and hbag negative. f/e/n: he received adequate resuscitation in the peri and postoperative periods which were reduced and then discontinued as his diet was advanced. he was able to advance his diet rather quickly and did quite well with this. electrolytes were frequently monitored and repleted as appropriate. at the end of his hospital stay, he began to diurese well and was helped along with iv lasix. he was sent home with an 8 day supply of po lasix to help get him get rid of his last excess fluid. he was also sent home with lantus and an insulin sliding scale while on steroids, having been seen by in house. he will follow up with them as an outpatient. immunosuppression: he was maintained on the typical liver transplant pathway, receiving mmf on admission and solumedrol in the or. he followed th pathway receiving tacrolimus, mmf and steroids per protocol. levels were followed and doses adjusted accordingly. steroids were tapered as usual and he was sent out on 20 of prednisone to be further tapered as an outpatient. he was taught how to take his meds with the self med program and he expressed understanding of this. overall, mr. had a smooth post-operative course and was able to be discharged home on pod 7 ambulating, tolerating a regular diet, with well-controlled pain. he will be closely followed in clinic. medications on admission: entacavir 0.5 mg daily discharge medications: 1. one touch ultra system kit kit : one (1) miscellaneous four
