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: interim history of present illness: in brief, this is a 26 and -week baby born here at , #1 of twins, to a 36-year- old g3, p1 mother. prenatal screens are unremarkable. maternal type is b+. vaginal delivery of twins. unstoppable preterm labor. developed a spontaneous ileal perforation with a volvulus, which was repaired at on day of life #5. he did well postoperatively. returned to the on where he continued his management of prematurity. hospital course: 1. respiratory: arrived on nasal prong cpap of 5 cm in room air. this was increased to 6 cm a day later due to increase in spells. he was maintained on caffeine citrate during this time and did well. he transitioned to nasal cannula oxygen at 200 cc on day of life #44 for 5 days. he returned to nasal prong cpap because of increased periodic breathing on day of life #49. on , he was reintubated because of increased apnea and desaturations during a decompensation. he was started on simv at settings of 18/5, and a rate of 20, and 25-30%; and was increased to settings today at time of transfer to 26/7, and a rate of 35, and anywhere from 40-100% oxygen. his last gas prior to leaving was 7.26, 72; requiring increasing rate. his chest x-ray was notable for a right upper lobe collapse and intermittent right lower lobe collapse as well. the endotracheal tube was midway between the carinae and the thoracic inlet. he has had moderate secretions. his caffeine was discontinued on . 2. cardiovascular: has been stable with mean pressures in the 40s to 50s. he has a cvl in place, which has been functioning well, that was placed for his initial surgery on . on , he had a transient decrease in his mean arterial pressure to 26, responding to a bolus of normal saline. he has not required pressors at this time. he had a peripheral arterial line placed in his left dorsalis pedis artery to monitor his mean pressures. his ap has been 120s to 140s. he had 1 episode of a mean pressure in the 60s earlier today, responding to a dose of fentanyl for presumed discomfort. 3. fluids, electrolytes and nutrition: on when returned from the , he was on total fluids of 140/kg of breast milk 20 calorie by continuous feeds. over the next 4 days he increased in calories to 24 per ounce. on , secondary to lethargy and a decreased urine output, a workup revealed a serum sodium of 118, a serum potassium of 8.9; necessitating a normal saline bolus and a sodium replacement infusion. he also received calcium gluconate x 1 dose and an insulin infusion with concurrent high glucose infusion to decrease his serum potassium. his ekg at this time remained normal. thereafter, his output was replaced cc-for-cc with half volume normal saline. it was reduced to half cc-for-cc replacement over time. a renal consult was obtained. serum and urine osmolarity were monitored, all of which were normal. a bun/creatinine at that time was noted to be elevated with a bun of 31 and a creatinine of 1.3, which corrected over the next 48 hours to 12 and 0.6. he was presumed to have renal insufficiency secondary to dehydration. the serum electrolytes continued to improve on this half-volume replacement with half normal saline, and he was transitioned off of his replacement on ; at which time oral sodium chloride and potassium chloride supplements were started. these have been weaned as well for serum sodium's of 140 and potassium's of greater than 5. on , his electrolytes were 135, 5.2, 106 and 19. also in relation to his fluids and electrolytes, was restarted on feeds on after the electrolyte aberration and quickly advanced to full volume. increasing calories on , was tolerating continuous feeds of breast milk 30 with beneprotein. this was made with 4 calories of human milk fortifier, 4 calories of mct, 2 calories of polycose and beneprotein as well. he transitioned to bolus slowly, going from continuous to being fed over 3-1/2 hours; and most recently tolerating bolus feeds over 2-1/2 hours. calories were reduced to 28 calories by eliminating the polycose due to increased output. total volume was increased to 150 ml/kg, which also increased output; so, the total fluids were trimmed to 140/kg of breast milk 28 with beneprotein over 2-1/2 hours. these were well tolerated. in addition, on , imodium was added to regimen to help decrease his output; and that was also well tolerated by . on , was made n.p.o. once again for frank in his stool from his . he was restarted on parenteral nutrition through his central broviac, which has remained in place. on day of transfer, he was receiving d-7.5 with 2.5 mg/kg of protein, 2 mg/kg of lipids, 3 meq/kg of sodium, and 3 meq of potassium - half chloride, half acetate. his glucose was noted to be elevated during the initial presentation with the frank bloody stools, peaking at 343. he responded to a single dose of subcutaneous insulin and has been euglycemic on a decreased gir as above. total fluids are at 130. he also has normal saline at ml/hour via peripheral arterial line. most recent set of electrolytes were at 11:00 a.m. on : sodium 134, potassium 3.6, chloride 101, and co2 of 29, glucose was 88. a copy of pn sheet was faxed over for your information on specific details related to the current parenteral nutrition. 4. gi: had drainage that averaged 1.2 to 2 ml/kg/hour of yellow, seedy, liquid stool. there were multiple changes in his bag over time secondary to skin breakdown. the nurse was involved with his care. he had breakdown from 9 o'clock until 3 o'clock, graphically speaking, around his stoma which is being treated. he, as i said, responded to fine-tuning of his fluid intake and imodium added to his dietary regimen. on , when was noted to have frank in his , a kub was obtained which showed dilated loops of the small bowel proximal to the stoma. serial kubs revealed nonspecific distention of several loops of bowel. on at 18:00 hours, he continued to have moderate distention of loops of bowel, mid abdomen, with a string-of-pearl appearance of bubbles seen in a concentric pattern in the left lower quadrant; suspicious of pneumatosis intestinalis. there was no free air identified in any of the serial films. his drains with scant amounts of bilious drainage. he was noted to have overlying erythema medial to the stoma of the skin. surgery continued to see the patient at the nicu, and at this time inserted a catheter into the stoma with return of frank . currently, there is minimal drainage from the stoma. lfts were obtained on with an alt of 65, an ast of 86. is being transferred to the surgery service for continued management of his abdominal process at this time. 5. infectious disease: on , during the decompensation secondary to electrolyte imbalance, had a sepsis evaluation - including , stool and urine cultures - all of which remained negative. he received 7 days of ampicillin and cefotaxime. on , he had a repeat sepsis eval secondary to his cvl dressing becoming contaminated. his cultures remained negative. his cbc was benign, and he completed 48 hours of vancomycin and cefotaxime. on , at the time of this abdominal process, again underwent a sepsis evaluation. he had , urine and stool cultures sent again on and . those cultures have remained negative. he was started on ampicillin, and gentamicin and clindamycin. due to the concern for cellulitis in the abdomen, vancomycin was also added. the ampicillin was discontinued on . his gentamicin levels on were 0.3 and 5.3. vancomycin on , levels were 13.6 and 31.1. 6. hematologic: is status post packed red cell transfusions. the has been made available through direct donor at from dad. received transfusions on , on , on . he received two 15 cc/kg prbc's transfusions. on , twenty per kilo of packed red cells. his hematocrit on is 42.5. the initial cbc on showed a white count of 10; a hematocrit of 35; platelets of 700,000; and nonshifted differential. on , his white count was noted to be 7.6; and at this time the differential was markedly shifted with 15 polys, 39 bands, 36 lymphs, and 8 myelos. he continued on antibiotics, and a repeat culture was sent at that time as well. on , his cbc was notable for a white count of 6.3, with 12 poly's, 8 bands, 43 lymphs, 18 monos, and 7 metamyelocytes. had coagulation studies performed on with a pt of 16.6, a ptt of 68.8, and inr of 1.5. on , a pt of 20, a ptt of greater than 150, a fibrinogen of 443 were reported; with a question of whether this was a half- absorbed specimen or not. there has been no further clinical evidence of active bleeding. has additional direct donor available that will be transferred with him to . 7. neurologic: head ultrasound on was normal for age. initial head ultrasound done at was notable for some echogenicities in the subependymal region of the frontal horns, and recommendation for mri at term was recommended by the radiologist at that time. subsequent head ultrasounds performed at the on and were considered to be normal for his age. his exam has been appropriate for his postmenstrual age. on , because of the acute abdominal process, was started on bolus doses of fentanyl at 2 mcg/kilo every 2 to 4 hours. on , was started on a 2 mcg/kilo per hour drip with good affect, requiring occasional boluses for procedural discomfort. 8. ophthalmology: an rop screen performed on showed immature retinae to zone 2. on , a repeat examination showed stage i zone 2 in the right and immature zone 2 in the left. followup is scheduled for this week. has not been performed at this time. 9. immunizations received: hepatitis b vaccine on , and a single dose of synagis on . newborn screens were sent on , , and . 10. social: parents are involved and concerned about the changing condition of at this time and have accompanied him to . his twin, , remains well. is growing and learning to feed at the nicu at the . discharge diagnoses: respiratory distress, sepsis suspect, necrotizing enterocolitis, retinopathy of prematurity, anemia of prematurity. name of primary pediatrician: not yet identified. feedings at time of transfer: n.p.o., pn as above. medications: include vancomycin, gentamicin, clindamycin, fentanyl. , md procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube enteral infusion of concentrated nutritional substances non-invasive mechanical ventilation arterial catheterization prophylactic administration of vaccine against other diseases transfusion of packed cells diagnoses: need for prophylactic vaccination and inoculation against viral hepatitis primary apnea of newborn neonatal bradycardia anemia of prematurity other specified conditions originating in the perinatal period retrolental fibroplasia septicemia [sepsis] of newborn hypospadias unspecified disorder of kidney and ureter other and unspecified atelectasis other transitory neonatal electrolyte disturbances other specified perinatal disorders of digestive system other colostomy and enterostomy complication
