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 51-year-old male with a complex past medical history, significant for recent diagnosis of osteomyelitis of the right tibia, who presented to on , for a scheduled debridement of the right tibia with concomitant rectus free flap reconstruction and split thickness skin graft. the patient was most recently an inpatient at from , to , at which point the diagnosis of right tibial osteomyelitis was confirmed via core biopsy conducted by the plastic surgery service of a right tibial lesion. at this time, the patient's biopsy was positive for pseudomonas, and the patient was started on a six week course of ceftazidime 2 grams intravenously every eight hours to be administered via picc line, with plans for subsequent scheduled debridement and reconstruction. the patient was instructed to present to the on , in preparation for debridement and reconstructions scheduled for . past medical history: post-traumatic stress disorder secondary to death of wife, hepatitis c, panic attack disorder, gastroesophageal reflux disease, previous right tibial skin graft secondary to motor vehicle accident, right total hip replacement secondary to motor vehicle accident, multiple fractures in secondary to motor vehicle accident. medications on admission: ceftazidime intravenously 2 grams via picc line every eight hours, protonix 40 mg by mouth once daily, celexa 30 mg by mouth every morning, norvasc 5 mg once daily by mouth, multivitamin one caplet by mouth once daily, vitamin c 1 gram by mouth once daily, neurontin 800 mg by mouth three times a day, klonopin 1 mg by mouth every 12 hours administered at 9 a.m. and 9 p.m., klonopin 0.5 mg by mouth every 12 hours, methadone 30 mg by mouth three times a day, dilaudid 8 mg by mouth every three hours as needed, ativan 1 mg by mouth every six hours as needed, benadryl 25 mg by mouth twice a day as needed, ambien 10 mg by mouth daily at bedtime as needed, maalox 30 cc by mouth every four hours as needed, compazine 5 mg by mouth every six hours as needed. allergies: penicillin and codeine reportedly promote a rash in the patient. trazodone causes headache. hospital course: the patient was admitted to the plastic surgery service on , under the direction of dr. . preoperative laboratory studies demonstrated a white blood cell count of 6.2, a hematocrit of 41.1. chemistries: sodium 137, potassium 4.4, chloride 102, bicarbonate 26, bun 16, creatinine 0.9, glucose 109. pt 13.5, inr 1.5, ptt 35.8. the patient was made nothing by mouth at midnight, and prepared adequately for surgery the next day. on , the patient underwent a right tibial debridement with a left rectus abdominis muscle free flap and split thickness skin graft from the left thigh to the right tibia reconstruction. the patient tolerated the procedure well, and received 6600 cc of fluid intraoperatively, with a urine output of 3225 and an estimated blood loss of 350 cc. no complications were noted, and a dopplerable pulse was obtained intraoperatively and at the end of the procedure. postoperatively, the patient was admitted to the surgical intensive care unit for close monitoring of his free flap. on postoperative day number one, the patient was noted to have stable vital signs and be afebrile. his flap demonstrated a dopplerable pulse, and his left lower extremity donor site dressing was noted to be intact, with minor serosanguinous drainage. the patient's pain, however, was poorly controlled via a fentanyl patient-controlled analgesia, necessitating institution of basal rate infusion in tandem with on-demand pain medication administration. on postoperative day number two, the patient was noted to be stable enough for transfer to the regular inpatient floor, where he remained for the duration of his admission. on postoperative day number three, the patient was fitted with an orthoplast posterior splint for his right lower extremity, to prevent equinus deformity. at this point, his flap was noted to continue to demonstrate dopplerable pulses. all incision lines were noted to be clean, dry and intact, with minimal drainage, and no evidence of erythema or purulence. due to continued breakthrough pain, however, the patient was evaluated by the chronic pain service, who recommended an increase in the patient's methadone dosage to 40 mg three times a day, with an oral dilaudid schedule of 8 to 12 mg by mouth every three to six hours as needed. on postoperative day number three, the patient's foley was also discontinued, and the patient was subsequently noted to be independently productive of adequate amounts of urine. the patient continued to remain stable and progressed well clinically through , at which point his intraoperative tissue cultures returned demonstrating klebsiella species, sensitive to imipenem and zosyn, and enterococcus species sensitive to ampicillin, levofloxacin, penicillin and vancomycin. an infectious disease consult was obtained, and the patient was subsequently recommended for continuance of vancomycin for a six week course via his picc line, discontinuance of his ceftazidime dosage, and institution of imipenem 500 intravenously every six hours for six weeks. electrolyte studies obtained at this point demonstrated adequate renal clearance, with a bun of 11 and a serum creatinine of 0.6. on , the patient was again noted to be afebrile, with stable vital signs, and was subsequently cleared for discharge to a rehabilitation facility, with instructions for long course intravenous antibiotic therapy and follow up with plastic surgery clinic. at the time of his discharge, the patient demonstrated a white blood cell count of 9.6, hematocrit 31.3, platelet count 307, sodium 139, potassium 4.3, chloride 102, bicarbonate 28, bun 11, creatinine 0.7, glucose 92. total protein was 6.7, albumin 3.4, total bilirubin 0.2, direct bilirubin 0.1. ast 35, alt 30, alkaline phosphatase 134, c-reactive protein 1.05. condition at discharge: the patient is to be discharged to a rehabilitation facility, with instructions for follow up. discharge status: stable. discharge medications: 1. pantoprazole 40 mg by mouth every 24 hours 2. citalopram 30 mg by mouth every morning 3. amlodipine besylate 5 mg by mouth once daily 4. multivitamin one capsule by mouth once daily 5. prochlorperazine 5 mg by mouth every

line until follow up instructions: the patient is to keep his right lower extremity flap clean and dry with xeroform and dry sterile dressing changes twice per day. the patient may sponge bath until follow-up appointment, but should pat dry his right lower extremity wound afterwards. no bathing until further notice. the patient's abdominal steri-strips will fall off on their own. the right lower extremity is strictly non-weight bearing. vancomycin and imipenem should be administered for a six week course via the picc line. the patient is to follow up in the plastic surgery clinic in one week following discharge. the patient is to call to schedule an appointment. activity instructions: the patient is to remain non-weight bearing on his right lower extremity. activity for the right lower extremity is limited to five minutes of dangling over the bed edge per hour per day. the patient may advance by five minutes per hour per week. the patient is to keep the right lower extremity elevated at all times while in bed or seated and when not dangling. , m.d. dictated by: medquist36 procedure: local excision of lesion or tissue of bone, tibia and fibula other skin graft to other
