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: was the first born of twins, a former 1.375 kilogram product of a 31 week gestation pregnancy, born to a 32 year old g2 p0 woman. prenatal screens: blood type o positive, antibody negative, rubella immune, rpr nonreactive, hepatitis b surface antigen negative, group b strep status unknown. the pregnancy was complicated by dichorionic, diamniotic twins with discordant growth. the mother also had a history of cervical shortening. she was betamethasone complete at the time of delivery. the infants were born by elective cesarean section due to increasing concerns for discordant growth. this twin #1 emerged vigorous, with apgars of 8 at one minute and 8 at five minutes. after delivery and stabilization, she was transferred to due to census issues at the neonatal intensive care unit. she was transferred back to the on day of life #12. her medical course at was significant for no cardiovascular or respiratory issues, initial maintenance on ivf with the gradual introduction of enteral feeds, which were well tolerated and reached full volume by dol #7, and treatment with phototherapy from dol #2 to dol #4 for hyperbilirubinemia. she received a 48 hour course of antibiotics over first two days of life as part of a sepsis evaluation; blood cultures were negative. in addition, over the first week of life, there was renal insufficiency noted, with a serum creatinine of 2.3 on odl #2, increasing to peak of 3.7 on dol #5. there was also mild hyperkalemia with potassium rising to 6.4 and hyperphosphatemia with phophorous rising to 6.9. mild hypercalcemia was also noted, with calcium rising to 11.3. urine output was normal throughout. renal ultrasound on dol #3 showed mild left hydronephrosis, mild right pelviectasis, and small bilateral renal cortical cysts. the renal service at was consulted, and overall the etiology of the renal insufficiency was unclear but thought to be secondary to placental insufficiency, perhaps complicated by reflux. the hyperphosphatemia and mild hypercalcemia required alterations of her enteral feeds from breast milk with hmf to breast milk with similac powder. she was started on amoxicillin urinary tract infection prophylaxis. on physical examination upon readmission to the neonatal intensive care unit, weight was 1.435 kg. general - non dysmorphic preterm infant in no distress. color pink in room air. head, eyes, ears, nose and throat - anterior fontanel soft and flat, symmetric facial features, positive red reflex bilaterally. chest clear, equal breath sounds, no murmur. pulses +2. abdomen soft, nontender, no masses. positive bowel sounds. genitourinary - normal preterm female. extremities straight, normal digits, nails and creases. neurologic - appropriate tone and reflexes, reflective of gestational age. hospital course by systems: 1. respiratory: remained in room air for her entire neonatal intensive care unit admission. she had rare episodes of apnea and bradycardia, but no apnea was noted for more than one week prior to discharge. several brief bradycardic episodes associated with discoordinated feedings were also noted, but none required stimulation and none were noted for over 24 hours at the time of discharge. 2. cardiovascular: remained normotensive, with normal heart rate. no murmurs were noted. recent blood pressure is 68/36, with a mean of 41. an echo was obtained on given the neurologic findings (see below), and that was normal without evidence of structural disease. 3. fen/renal: maximum caloric intake was breast milk fortified to 28 calories per ounce, initially with similac powder and mct oil; as mentioned above, powder was used rather than hmf secondary to concerns for hypercalcemia and hyperphosphatemia. she advanced readily from pg to po feedings, and with adequate weight gain, caloric density was decreased to 26 calories per ounce. she was noted to have an elevated alkaline phosphatase, with a level of 752 on dol #15 and 851 on dol #25. calcium and phosphorous levels were normal at that time. the elevated alk phos was thought to be consistent with mild metabolic bone disease of prematurity, complicated by renal insufficiency and lack of sufficient supplemental calcium and phosphorous. at that time, renal function had improved, with creatinine decreasing to 1.6, and feedings were changed to breast milk with hmf. laboratory studies were monitored, with gradual decline in alk phos noted, no elevations in calcium or phosphorous, and continued improvement in renal function. her most laboratory studies on included ap 463, ca 10.0, phos 6.2, bun 25, and creatinine 1.2. feedings were changed on dol #31 to breast milk with neosure powder in anticipation of discharge, and at discharge, she is taking breast milk with neosure powder to 26 cals per ounce. weight on the day of discharge is 2.200 kg. she has been maintained on supplemental vidaylin (which contains vitamin d) throughout. she will require follow-up with the renal service at (dr. , ) 4-6 weeks after discharge, and a vcug has been scheduled for at at 9:30 am. periodic monitoring of renal function and chemistries including calcium, phosphorous, and alkaline phosphatase is recommended. 4. infectious disease. as previously noted, is being treated with amoxicillin for urinary tract infection prophylaxis. there were no other infectious disease issues since her transfer from . she should remain on amoxicillin until results of vcug are available. 5. hematology: most recent hematocrit was on at 34 percent. the reticulocyte count was 3.5 percent. she is being discharged home on supplemental iron. 6. neurology: has maintained a normal neurological exam throughout admission. initial head ultrasound on was within normal limits. follow-up head ultrasound on dol #32, , was notable for the unexpected finding of a large cystic structure in the left parieto-occipital region, with an additional small right subependymal bleed. no hydrocephalus was noted. the cystic lesion was concerning for periventricular leukomalacia, although location was unusual and no other white matter injury was seen. mri on confirmed the large left cystic lesion without evidence of other injury. neurology and neurosurgery were consulted, and overall, the findings were thought to be most consistent with an extraaxial cyst such as an arachnoid cyst. other possiblities were a benign tumor such as a dermoid cyst and a porencephalic cyst reflecting evolution of a previous infarct. this was thought to be unlikely given that the rest of the mri was normal. repeat ultrasounds on and were basically unchanged, with the cyst measuring approximately 2.4 x 1.9 x 1.8 cm, and no change of the right subependymal hemorrhage. head circumferences were followed daily and remained stable at 30-30.5 cm. due to the possibility, although unlikely, that lesion could have reflected evolution of an old infarct, echo was obtained to assess for possible right- to-left shunts, and this was normal without evidence of asd or vsd. of note, infant was noted to be mildly lethargic for 36 hours after the mri, but this was attributed to sedation given for the study, and resolved without intervention. given stable nature of lesion and normal neurologic exam, infant was deemed appropriate for discharge with suitable follow- up. head ultrasound has been scheduled for at at 11 am, follow-up with the neonatal neurology program at has been scheduled for at 1pm, and follow- up with neurosurgery has been scheduled with the family for . head circumference should be followed weekly for now as screen for progressive enlargement of the lesion or development of hydrocephalus. early intervention and close monitoring of development is also recommended given uncertain nature of lesion. 8. sensory. audiology - hearing screening was performed with automated auditory brainstem responses. passed in both ears. ophthalmology - eyes were most recently examined on , and retinas were found to be mature bilaterally. ophthalmology followup is recommended in 9 months. 9. psychosocial. social work was involved with this family. the contact social worker is , and she can be reached at . the case management nurse , and she can be reached at . baby's surname after discharge will be cisler. condition

powder or neosure formula concentrated to 26 calories per ounce. the neosure is recommended until 6-9 months of corrected age. 2. medications: amoxicillin 40 mg p.o. once daily, ferrous sulfate 25 mg/ml 0.3 ml once daily, vi-daylin 1 ml p.o. once daily. 3. car seat position screening was performed. was observed in her car seat for 90 minutes without any episodes of bradycardia or oxygen desaturation. 4. state newborn screens were sent on and . all results were within normal limits. a repeat screen was sent on , with no notification of abnormal results to date. 5. immunizations received: hepatitis b vaccine was given on . immunizations recommended: synergist rsv prophylaxis should be considered from through for infants who meet any of the following three criteria: 1). born at less than 32 weeks. 2). born between 32-35 weeks with two of the following: day care during rsv season, a smoker in the household, neuromuscular disease, airway abnormalities or school age siblings. 3). with chronic lung disease. influenza immunization is recommended annually in the fall for all infants once they reach six months of age. before this age, and for the first 24 months of the child's life, immunization against influenza is recommended for household contacts and out of home caregivers. followup appointments scheduled or recommended: 1. appointment with dr. 1-2 days after discharge. 2. a voiding cystourethrogram at on , at 9:30 a.m., with head ultrasound at 11 a.m. 3. dr. , renal service, , , four weeks after discharge. 4. neonatal neurology, , , 1pm. 5.
