Evaluate the following neonatal clinical scenarios and match each patient's presentation with the most appropriate targeted pharmacologic therapy or initial management strategy.
- A 3-day-old infant with a head circumference below the 3rd percentile. Cranial ultrasound shows periventricular calcifications. The infant failed the newborn hearing screen bilaterally.Oral valganciclovir
- A 2-day-old infant with macrocephaly. Non-contrast head computed tomography reveals diffuse, scattered intracerebral calcifications. Ophthalmologic exam shows chorioretinitis.Pyrimethamine, sulfadiazine, and leucovorin
- A 1-day-old infant with a grade 3/6 continuous machinery murmur at the left upper sternal border, absent red reflexes bilaterally, and bilateral sensorineural hearing loss.Supportive care and contact precautions
- A 12-day-old infant with lethargy, temperature instability, and a cluster of fluid-filled vesicles on the fetal scalp monitor site. Cerebrospinal fluid analysis reveals lymphocytic pleocytosis.Intravenous acyclovir
- A 16-day-old infant with copious purulent eye discharge, a respiratory rate of 65/min, and a repetitive staccato cough. Chest radiography reveals bilateral interstitial infiltrates.Oral azithromycin
Cevap
Congenital CMV with Valganciclovir; Congenital Toxoplasmosis with Pyrimethamine, sulfadiazine, and leucovorin; Congenital Rubella with Supportive care; Neonatal HSV with Intravenous acyclovir; and Neonatal Chlamydia with Oral azithromycin.
Congenital CMV is treated with oral valganciclovir. Congenital toxoplasmosis requires pyrimethamine, sulfadiazine, and leucovorin. Congenital rubella has no specific antiviral therapy and requires supportive care and isolation. Neonatal HSV is treated with intravenous acyclovir. Neonatal chlamydia requires a macrolide such as oral azithromycin.
