Drug Dosing: Infants and Children

324
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.

Summary

Choroidal osteoma, a rare bone tumor in the eye, was found in a 4-week-old premature infant. This case highlights that choroidal osteoma can occur even in newborns, challenging previous age assumptions.

Area of Science:

  • Ophthalmology
  • Oncology

Background:

  • Choroidal osteoma (CO) is a rare, benign intraocular tumor composed of mature bone.
  • Typically observed in young adult females, CO presents as a yellowish-white or orange choroidal mass.

Observation:

  • A 4-week-old premature infant presented with a choroidal osteoma in the left eye.
  • The tumor was incidentally detected during a routine examination for retinopathy of prematurity.

Findings:

  • This represents the youngest reported case of choroidal osteoma to date.
  • The presence of CO in such a young infant suggests the condition can manifest neonatally.

Implications:

  • This case expands the known age range for choroidal osteoma diagnosis.
  • Early detection protocols may need to consider CO in premature infants, even when screened for other conditions.
