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: baby girl (twin i) delivered at 28-3/7 weeks gestation, weighing 1235 grams, who was admitted to the intensive care nursery for management of prematurity and respiratory distress. the patient is a 22-year-old gravida 3, para 1 (now 3) woman with an estimated date of delivery of . prenatal screens included blood type o positive, antibody screen negative, hepatitis b surface antigen negative, rapid plasma reagin nonreactive, rubella immune, and group b strep unknown. her past obstetrical history was notable for a spontaneous vaginal delivery at 42 weeks gestation in the year and a therapeutic abortion times one. this pregnancy was a spontaneous dichorionic-diamniotic twin gestation complicated by the spontaneous onset of cervical dilation and a urinary tract infection on admission to . the mother was treated with ampicillin and received betamethasone. delivery was by cesarean section for breech presentation due to progressive cervical dilatation. the membranes were ruptured with clear fluid at delivery. no maternal fever. on delivery, cried on delivery but required stimulation for inconsistent respiratory effort. due to increased respiratory distress, she was intubated in the delivery room. apgar scores were 7 at one minute and 8 at five minutes. physical examination on presentation: physical examination on admission revealed weight was 1235 grams (75th percentile), head circumference was 27.5 cm (75th percentile), and length was 38.5 cm (50th to 75th percentile). anterior fontanel was soft, flat, and nondysmorphic features. the palate was intact. the neck and mouth were normal. moderate intercostal and subcostal retracting, decreased breath sounds bilaterally, and coarse crackles throughout both lung fields. well perfused. a regular rate and rhythm. normal first heart sounds and second heart sounds. femoral pulses were normal. the abdomen was soft and nondistended with a 3-vessel umbilical cord. no organomegaly. no masses. bowel sounds were active. genitourinary revealed normal female genitalia. active and alert. normal tone for gestational age. the spine was intact. the hips were stable. hospital course by issue/system: 1. respiratory issues: the infant received two doses of survanta for respiratory distress syndrome. maximum ventilator support pressure was 22/5 with a rate of 25. was briefly on 100% oxygen but very quickly weaned down to 30% and then room air. the infant was extubated on day of life one to room air. required supplemental oxygen by nasal cannula from day of life 9 to day of life 30. the infant has remained on room air since with comfortable work of breathing. respiratory rates were in the 30s to 50s. the infant received caffeine citrate for apnea of prematurity. the caffeine citrate was discontinued on day of life 34 (on ). the last bradycardic episode was on . 2. cardiovascular system: the infant received indocin on day of life two for a moderate patent ductus arteriosus with continuous left-to-right flow by echocardiogram. a follow-up echocardiogram after treatment showed no patent ductus arteriosus. she did not have a murmur on discharge. her recent blood pressure was 80/51 with a mean of 69. 3. fluids/electrolytes/nutrition issues: initially, the infant was maintained on d-10-w then total parenteral nutrition until advanced to full feeds. enteral feeds were started with premature enfamil 20 calories per ounce on day of life five. she advanced to full volume feeds on day of life 14. the feeds were stopped on day of life 15, and she was nothing by mouth for two weeks for treatment for medical necrotizing enterocolitis. the feeds were restarted on day of life 29 and advanced to full feeds on day of life 35 without problems. the calories were increased to 24 calories per ounce with good weight gain. on day of life 53, she developed frank bloody stools and was made nothing by mouth again for 24 hours. her abdominal examination and abdominal films were normal. a sepsis evaluation was negative. feeds were started again, but the infant had blood in stool again and was again made nothing by mouth for three days. a lower gastrointestinal series done because of a history of medical nec rxed in the 3rd week of lie showed no strictures. her evaluation and clinical course suggested a milk protein intolerance, and she was started on pregestimil formula which she has tolerated well. she is currently taking pregestimil 20 calories per ounce ad lib, taking three to four ounces every four hours with good weight gain. there has been no frank blood in her stool, but her stools have continued to be very trace guaiac-positive. discharge weight was 3305 grams. 4. gastrointestinal issues: the infant was treated with ampicillin, gentamicin, and clindamycin for 14 days for medical necrotizing enterocolitis from day of life 16 to day of life 29. frank bloody stools on cow-milk formula were thought to be due to a milk protein intolerance which was treated with pregestimil formula. she was treated with phototherapy during the first couple weeks of life for indirect hyperbilirubinemia. her peak total bilirubin was 6.5 and total bilirubin was 0.3. 5. hematologic issues: blood type is o positive. she received a transfusion of one unit of packed red blood cells on day of life 11 for a hematocrit of 26.3%. a recent hematocrit on was 23.6% with a reticulocyte count of 5.2%. a previous hematocrit on showed a hematocrit of 24.7% and a reticulocyte count was 12.3%. it was recommended that hematocrit and reticulocyte count be repeated one week after discharge. she is receiving supplemental iron; around 2 mg/kg per day. 6. infectious disease issues: the infant received a 7-day course of ampicillin and gentamicin following admission for presumed sepsis. her blood cultures were negative. her lumbar puncture was negative. the infant received 14 days of ampicillin, gentamicin, and clindamycin from day of life 16 to day of life 29 for medical necrotizing enterocolitis. the infant received 48 hours of ampicillin and gentamicin for rule out sepsis and necrotizing enterocolitis when she initially presented with bloody stools on day of life 52. complete blood count was benign and blood cultures were negative. 7. neurologic issues: a head ultrasound on day of life eight and at one month of age was normal. 8. sensory issues: (a) auditory: hearing screen was performed with automated auditory brain stem responses and passed in both ears. (b) ophthalmology: eyes examined most recently on revealing a stage i retinopathy of prematurity, in zone 3, has one to two clock hours on the right and two to three clock hours on the left. the ophthalmologist recommended a follow-up examination in three to four weeks (which would be either the week of or for a follow-up examination). 9. psychosocial issues: social work was involved with the family. the contact social workers is , and she can be reached at telephone number . a 51a has been filed. condition at discharge: a growing 66-day-old former 28-3/7 weeks and now 37-6/7 weeks corrected age. discharge disposition: primary pediatrician: care and recommendations: 1. feeds: pregestimil 20 calories per ounce ad lib demand. 2. medications: ferrous sulfate 0.25 cc p.o. daily. 3. hematocrit and reticulocyte count recommended one week after discharge. 4. car seat position screening was passed. 5. state newborn screening has been done on several occasions and all have been normal. immunizations received: 1. received first hepatitis b immunization on and second hepatitis b immunization on . the infant will need a fourth dose of hepatitis b immunization as she was premature and had her first dose at less than 2 kilograms. she received her first dose of hepatitis b immunization after delivery, as the mother's status was not known at that time. subsequently, the mother's status was known to be hepatitis b negative. 2. received 2-month immunization on which included dtap, hib, ipv, and pcv7. discharge instructions/followup: 1. follow up with pediatrician. 2. early intervention program. 3. visiting nurse. 4. infant follow-up program. 5. ophthalmology appointment to be scheduled. discharge diagnoses: 1. appropriate for gestational age preterm female infant born at 28-3/7 weeks gestation. 2. twin i. 3. respiratory distress syndrome; resolved. 4. patent ductus arteriosus; resolved. 5. apnea of prematurity; resolved. 6. indirect hyperbilirubinemia; resolved. 7. presumed sepsis; resolved. 8. medical necrotizing enterocolitis; resolved. 9. ruled out sepsis times one. 10. anemia. 11. retinopathy of prematurity. 12. milk protein intolerance. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified spinal tap incision of lung diagnostic ultrasound of heart insertion of endotracheal tube enteral infusion of concentrated nutritional substances other phototherapy prophylactic administration of vaccine against other diseases audiological evaluation extended ophthalmologic work-up diagnoses: unspecified septicemia twin birth, mate liveborn, born in hospital, delivered by cesarean section respiratory distress syndrome in newborn neonatal jaundice associated with preterm delivery 27-28 completed weeks of gestation septicemia [sepsis] of newborn other preterm infants, 1,000-1,249 grams late metabolic acidosis of newborn
