when does anorectal malformation generally occur?
during 4th to 12th week of fetal development
how is imperforate anus classified?
as high or low in relation to levator muscles
single opening for urethra, rectum, and vagina
most common cause for abdominal surgical procedure in child aged 5-10 years
how can appendectomy be performed?
laparoscopy or open laparotomy
how is questionable diagnosis of appendicitis confirmed or ruled out?
with what condition is cryptorchidism associated?
operation performed for cryptorchidism
two-stage Torek operation
when is cryptorchidism usually repaired?
at age 5 or 6 years
treatment for congenital dislocated hip if diagnosed early in infancy
closed reduction with immobilization
treatment for congenital dislocated hip if diagnosed after child has begun to walk
open reduction with osteotomy to stabilize the joint
otherwise known as clubfoot
treatment for talipes varus during infancy
treatment for talipes varus in older, weightbearing child
wedge cast with turnbuckles
most common chronic condition of childhood
secretory otitis media
incision in tympanic membrane for drainage

cleft lip rules of 10
10 weeks of age
10 g hemoglobin
10 lbs body weight
fusion of two or more fingers or toes
most common congenital hand deformity
webbing between fingers
what does separation of webbed digits almost always necessitate?
occurs when passages between ventricles are blocked and dilated by accumulated CSF
how is hydrocephalus treated in utero?
cephalocentesis with insertion of ventriculoamniotic shunt to drain ventricles
how is hydrocephalus treated after birth?
implantation of shunt for transporting excess fluid from ventricles
funnel-shaped concave depression over lower end of sternum
what can result from extreme pectus excavatum during pubertal growth period?
procedures for pectus excavatum
Nuss procedure - minimally invasive
Ravitch repair - open
when is pulmonary ventilation established?
during first breath at birth
this causes increased left atrial force, which closes foramen ovale
when does ductus arteriosus close after birth?
after 15 hours
some neonates have delay of 1-3 weeks for complete closure
opening in septum between right and left atria, allowing oxygenated blood to shunt from left to right and return to lungs
atrial septal defect
2 ways atrial septal defect can be repaired
closed with sutures
if cannot be closed with sutures, patch graft is inserted
opening in membranous portion of septum between right and left ventricles
ventricular septal defect
repair of ventricular septal defect
patients with small defects may not necessitate repair - 1/3 small defects close spontaneously by age 2
patch graft is used to repair large defects

procedure in which aorta and pulmonary arteries are anatomically switched
why is Jantene procedure done?
infants with VSD or large PDA
absence of tricuspid valve between right atrium and ventricle, preventing normal blood flow through chambers of the heart
treatment for tricuspid atresia
Fontan procedure - performed at 3 or 4 years of age - direct anastomosis of pulmonary artery to right atrium
a balloon catheter is advancd into the right atrium, through foramen ovale and into left atrium, balloon inflated and pulled back, enlarging foramen ovale

theories of aging
wear-and-tear theory - body loses ability to keep pace

viral theory - viruses use genetic materials to fool immune system
environmental theory - environmental elements accelerate aging process
physical factor theory - free radicals may cause premature aging
in physical factor theory, hormonal activities affecting organ systems
decrease in estrogen production = increased risk for osteoporosis and heart disease
decrease in thyroid activity decreases basal metabolic rate and increases weight gain
decrease in efficiency of insulin production decreases efficiency of glucose metabolism
decrease in testosterone production = decreased libido in men
