Items To Review Flashcards
Pompes Disease
GSD2,
PKU (and a similar disorder)
Deficiency of PAH (converts phenylalanine to tyrosine), P toxic to brain, T needed for melanin = fair eyes/hair
Similar disorder - tetrahydrobiopterin (PAH cofactor)
Abnormal odor and IEM:
Maple syrup
Boiled cabbage
Fish
Sweaty foot
MSUD
Tyrosinemia
3 methylcrotonylglycinuria
Glutaric aciduria 2
Galactosemia
Galactose 1 phosphate uridyltransferase def (GALT)
Poor feeding lethargy jaundice cataracts E. coli sepsis
Tx: dietary restriction (no lactose). Even with tx can have mental retardation.
Girls have premature ovarian failure.
MCAD def
Most common d/o fatty acid oxidation.
Usually asymptomatic as neonate. Can have vomiting, HM, lethargy, coma, seizures with fasting or an illness.
Increased C6-10 acylcarnitines.
Ectopic atrial contraction
180-240 bpm
Speeds up and slows down
Atrial contraction before vent ctx
HLHS management
Norwood palliation. Atrial septectomy and convert RV into the main ventricle for pulm and systemic flow. MPA and Ao are connected, MPA disconnected from PAs. Shunt placed from PA to lungs.
Then Glenn then fontan.
Tx for SVT
Tx for AV reentry tachycardia
SVT - digoxin
AVRT - amiodarone
Hydrocortisone mechanism
Inhibit NO synthase
Upregulate adrenergic receptors
Upregulate angiotensin II receptors
Inhibit catecholamine metabolism.
Increase intracellular Ca.
Milrinone mechanism
Phosphodiesterase 3 inhibitor. Decreases breakdown of cAMP = increases Ca influx to cells.
Inotropic, inodilator, lusitrope.
Norepi mechanism
Activates alpha1,2 and beta1 receptors to increase SVR and CO. Greater systemic constriction than pulmonary
Ebstein anomaly associated with which EKG abnormality
RBBB. Also WPW
DM CHD
VSD
DORV
TA
HCM in IDM
Histologically different than congenital HCM. Caused by insulin and hyperglycemia. Supportive care, can be reversible, treatment includes beta blockers to improve ventricular output.
Most common cause hypertrophic cardiomyopathy and Tx
Noonans
Beta blocker
