Reversible renal medullary hyperechogenicity in neonatal hypernatremic dehydration

Abstract: Three exclusively breastfed term neonates were admitted with lethargy, poor feeding, and oligoanuria. All three babies were severely dehydrated and had a weight loss ranging from 18% to 40%. Serum sodium of more than 180 mEq/l and renal failure were observed in all three. Two had very high creatinine levels of 9.5 mg/dl and 6.7 mg/dl. Both these babies also had multiple seizures. One baby required mechanical ventilation. All three babies showed markedly hyperechoic renal medullary pyramids with speckled foci s… Show more

“…After lactogenesis stage II occurs, a breastfed infant's number of voids and stools each day is sensitive to the infant's breast milk intake. At that time insufficient breast milk intake is often associated with oliguria, weight losses over 10% from birth weight, and dehydration (Ali et al, 2004; Livingstone et al, 2000; Ng et al, 1999; Sachs & Oddie, 2002; Yaseen et al, 2004). However, prior to the occurrence of lactogenesis II, voiding and stooling frequencies are normally minimal (AAP; ILCA).…”

“…Measuring breastfeeding frequency and the frequency of infant voids and infant stools is often considered sufficient for determining if an infant's breast milk intake is adequate after the infant is 4 to 5 days of age (AWHONN; Iwinski, 2006). Furthermore, there is considerable research supporting the relationship between breast milk transfer and infant weight changes, voids, and stools following lactogenesis at 2 to 4 days postpartum (Ali et al, 2004; Ng et al, 1999; Yaseen, Salem, & Darwich, 2004).…”

“…Medullary hyperechogenicity has been described in human neonates and is considered a normal variant if it disappears within 10 days 16 . Other conditions in which hyperechogenicity can be seen in the medulla include diffuse glomerulosclerosis and hypernatremic dehydration where the hyperechoic foci are thought to be crystal depositions 17,18 …”

“…El manejo de esta condición clínica en recién nacidos sigue siendo controvertida porque los neonatos tienen signos clínicos de deshidratación menos evidentes y son más susceptibles a la deshidratación por la inmadurez renal, la distribución de agua corporal y porque las necesidades de agua y sodio son diferentes en niños mayores 8 . Cuando los recién nacidos no son tratados adecuadamente, pueden tener graves complicaciones y secuelas neurológicas a largo plazo.…”
