Newborn Jaundice (Neonatal Jaundice)
Jaundice in newborns and babies (neonatal jaundice) usually occurs because of a normal increase in red blood cell breakdown and the fact that their immature livers are not efficient at removing bilirubin from the bloodstream. Symptoms of jaundice are fever, poor feeding, and looking ill. Newborn jaundice is very common and is caused because the newborns liver isn’t mature enough to remove bilirubin from the blood. Treatment of jaundice in newborns include phototherapy, tanning booths, and other treatments.
Cerebral palsy (CP) is an abnormality of motor function and postural tone acquired at an early age (even before birth). Cerebral palsy is generally caused by brain trauma. Types of cerebral palsy include: spastic, dyskinetic (dystonic or choreoathetoid), hypotonic, and mixed types.

Human Immunodeficiency Virus (HIV)
HIV (human immunodeficiency virus) infection left untreated causes AIDS (acquired immunodeficiency syndrome). Still incurable, AIDS describes immune system collapse that opens the way for opportunistic infections and cancers to kill the patient. Early symptoms and signs of HIV infection include flu-like symptoms and fungal infections, but some people may not show any symptoms for years. Highly active antiretroviral therapy (ART) is the standard treatment for HIV infection. These combination drug regimens have made HIV much less deadly, but a cure or vaccine for the pandemic remains out of reach. HIV is usually transmitted through sexual contact or sharing IV drug needles, but can also infect someone through contact with infected blood. Sexual abstinence, safe sex practices, quitting IV drugs (or at least using clean needles), and proper safety equipment by clinicians and first responders can drastically reduce transmission rates for HIV/AIDS.
Hearing loss (deafness) may be present at birth or it may manifest later in life. Deafness may be genetic or due to damage from noise. Treatment of deafness depends upon its cause. Sensorineural hearing loss can be caused by conditions affecting the cochlea, eighth cranial nerve, spinal cord, or brain. Examples of conditions that can lead to sensorineural hearing loss include Meniere's disease, noise-induced hearing loss, hearing loss of aging (presbycusis), nerve injury from syphilis, hearing loss of unknown cause (idiopathic hearing loss), nerve tumors, and drug toxicity (such as aspirin and aminoglycosides).
Birth defects have many causes and currently, are the leading cause of death for infants in the first year of life. Some of the causes of birth defects include genetic or chromosome problems. Exposure of the mother to rubella or German measles during pregnancy, or using drugs or alcohol during pregnancy. The treatment for birth defects depends upon the condition of the effected child.
Hydrocephalus is an abnormal buildup of cerebrospinal fluid (CSF) in the ventricles of the brain. The fluid is often under increased pressure and can compress and damage the brain. Symptoms of hydrocephalus vary with age, progression of the disease, and individual tolerance to the condition. Hydrocephalus is most often treated by surgery in which a shunt system is inserted.
Jaundice (Newborn, Kernicterus)
Jaundice in infants occur when the baby's liver may not be developed enough to efficiently rid the body of bilirubin. Symptoms of jaundice include yellowish colored eyes, and yellowing of the skin. Some babies are more at risk to develop jaundice. Kernicterus is a type of brain damage that occurs when a baby has jaundice and is not treated. Treatment of infant jaundice is generally with phototherapy so that kernicterus should not develop.
