Congenital Adrenal Hyperplasia

Congenital adrenal hyperplasia (CAH) affects the adrenal glands, which make important hormones. Symptoms depend on a child's age, sex, and which hormones the adrenal glands make too little or too much of.

Dialysis

Dialysis is a medical treatment that can take over the job of cleaning the blood when the kidneys can't.

Glomerulonephritis

Glomerulonephritis happens when tiny filtering units in the kidneys stop working properly. Most cases get better on their own or with treatment.

Hemodialysis

Hemodialysis is a medical treatment that uses a machine with a special filter to take waste and extra water out of the blood.

Henoch-Schönlein Purpura (HSP)

Most kids who develop this inflammation of the blood vessels (marked by a raised red and purple rash) make a full recovery and have no long-term problems.

Hydrocele

A hydrocele is a pouch of fluid around the testicle inside the scrotum. Hydroceles are common in newborns, especially preemies.
