Phenylketonuria (PKU) is a genetic amino acid metabolism disorder where the body cannot properly metabolize phenylalanine, leading to the accumulation of phenylalanine and its metabolites in the body, which damages the nervous system and manifests as symptoms such as intellectual disability, epilepsy, and unusual urine odor. Treatment involves special diets and medications to lower the concentration of phenylalanine in the blood, preventing damage to the nervous system.

A slightly elevated thyroid hormone level in newborns usually doesn’t require concern; regular retesting is sufficient. If the level is significantly higher, it’s advisable to consult a hospital for further examination.

Infantile spasms, also known as West Syndrome or the opisthotonic syndrome, can lead to sequelae as they grow up, but proper treatment can stabilize the condition.

Neonatal echocardiography is generally safe with no known major side effects. However, any medical procedure carries a risk, though typically very low.

It’s important that echocardiography can help doctors assess neonatal heart function, detect any potential issues early, and allow for timely treatment.

Neonatal hearing screening is an objective, rapid, and non-invasive examination conducted through auditory emissions, automatic auditory brainstem response, and acoustic impedance, etc., in the natural sleep or quiet state of newborns after birth.

The symptoms of osteomylitis include pain, swelling, and limited function, while the treatment methods include physical therapy, medication, and rest.

Hand, Foot, and Mouth Disease may not cause fever, but it can lead to scattered blisters on the hands, feet, and buttocks. Even without fever, it’s important to monitor the child’s mental state and appetite. If the child shows signs of fatigue and loss of appetite, they should be taken to the hospital immediately for routine blood tests and checks for Coxsackie virus and EV71. If the results are positive, further observation and treatment may be necessary. Hand, Foot, and Mouth Disease can have serious implications for children, so it is recommended that parents bring their child to a specialist clinic for a follow-up examination and treatment under a doctor’s guidance.
