Final Exam Flashcards
what is myelodysplasia (spina bifida)
birth defect or neural tube and spinal columns when the spinal verbtrea do not close/fuse
when does myelodysplasia occur
fetal period (first 28 days of first trimester)
types of neural tube defects
anencephaly
porencephaly
iniencephaly
encephalocele
anencephaly
brain deformity where parts of brain are missing
porencephaly
brain develops fluid filled cysts
iniencephaly
extreme retroflexion of head
encephalocele
sack like protrusion of brain and membranes through the skull
4 types of myelodysplasia
occulta
closed neural tube defects
meningocele
myelogeningocele
occulta
mildest and most common form
1+ vertebrae malformed
rarely causes disability or symptoms
closed neural tube defects
spine may have malformations of fat, bone, or membranes covering SC
usually requires surgery in childhood causing LE weakness and trouble with bowel/ bladder control
meningocele
sac of spinal fluid protrudes through spine
may have minor symptoms
myelomeningocele
most severe form
part of SC or nerves exposed in sac through opening in spine
need surgical closure in utero or right after birth
changes in brain structure, LE weakness, bowel/ bladder
lower spinal level= less symptoms
causes of myelodysplasia
genetics
exposure to teratogen (alcohol, drugs)
nutritional deficits
overall unknown etiology
what is the most common permanently disabling birth defect in the US
myelodysplasia
how population groups have highest prevalence of myelodysplasia
hispanic women
celtic region
why is the incidence of myelodysplasia decreasing
better nutrition
better screening
better med care
prevention of mylodysplasia
folic acid
counseling for women with a child or siblings with spina bifida
diagnosis of spina bifida prenatally
maternal alphafetoprotein (AFP) test- blood test
ultrasound- look for lemon sign before 24 weeks
amniocentesis- check AFP levels from amniotic fluid
diagnosis of spina bifida post natally
hairy patch of skin or dimple of baby’s back and use imaging
co-occuring conditions with spina bifida
hydrocephalus
Arnold chiari
ortho conditions
bowel and bladder conditions
obesity
precocious puberty
skin breakdown
overuse injuries
medical interventions for spina bifida
fetal surgery (repair)
neurosurgical treatment for hydrocephalus
shunting (VP, VA, ETV)
redirect CSF flow elsewhere
normalize CSF flow and fix pressures in skull
mobility precaution for hydrocephalus neurosurgical treatment
no prolonged head inversion
neurosurgery of hydrocephalus (ETV)
alternative to shunting by creating stoma at based of 3rd ventricle to allow for CSF drainage
longer lasting and more natural but could have serious complications
signs of shunt malfunctions in older kids
headache
blurred vision
drowsiness
LOC
lethargy
signs of shunt malfunction in infants
rapid head growth
bulging soft spot at frontal
swelling/pain along shunt
irritable
nausea and vomitting
crossed eyes/ sunset eyes
apnea
drowsiness
trouble drinking, swallowing, crying
signs of infected shunt
fever
neck stiffness
redness
leakage
abdominal pain
ACM type 1
mild
protrusion of tonsils through foramen magnum
ACM type 2
most severe
protrusion of vermis and brainstem through foramen magnum
ACM most common symptoms
inspiratory stridor
symptoms of ACM in kids with SB
1/3 of individuals
difficulty swallowing
poor feeding
weak cry
stiff arms/hands
selective loss of sensation in hands/ arms
cerebellar symptoms
what to avoid with ACM
excessive neck flexion
what is tethered cord
SC attached to spinal column restricting movement of SC which reduces BF and causes damage
what part of spine does tethered mostly occur in
lumbar spine
symptoms of tethered cord
sensory disturbance, significant muscle weakness, spasticity, increased tone and incontinence
changes in gait
LL or scoliosis
inwards turned feet
tripping
when to watch out for tethered cord
periods of skeletal growth
two conditions that commonly occur with spina bifida
tethered cord and ACM
diagnosis of tethered cord
CT or MRI
clinical signs and symptoms
change in pain, loss of muscle function, gait, bowel/ bladder
ortho conditions often seen with spina bifida
contractures of hip, knee, Ankle
hip dislocation
scoliosis and kyphoscsliosis
gibbous deformity
club feet
what is gibbous deformity
kyphosis with 3+ vertebral segments with sharp angle of spin
who treats kids with spina bifida
interprofeessional team
services for kids with spina bifida
neurosurgical management
urological care
bowel management
ortho care
developmental and neuropsychological educational evals
patient/fam edu
mental health screening
sleep studies
independence training
social work
transition to adult services
3 main reasons for PT exam spina bifida
define current status for program planning
ID potential for developing secondary impairments and make preventative measures
monitor changes in status
infancy age range (SB)
0-11 months
preschool age range (SB)
1-5 yo
school aged range (SB)
6-12 yo
adolescents-adulthood (SB)
13-21 yo
what is grade 0-3/5 iliopsoas associated with
partial or complete reliance on WC mobility
what is grade 4-5/5 iliopsoas strength associated with
community ambulation in most patients
what is grade 4-5/5 glute and anterior tibial associated with
community ambulation without aids or braces
what muscles are most important for forward propulsion
hip extensors and calves
what does mid- lower lumbar levels do during ambulation
shift trunk side to side
things to find out during exam for SB
motor level (MMT) and look at functional movement and sensory level
communicate with fam and medical team
ID challenges and goals
determine need for equipment
PT interventions for spina bifida
direct intervention (clinic, school community)
patient edu/ HEP
collaboration/communication
consider positioning and mobility programs
consult and monitor
what to include in HEP for SB
ROM, strengthening, positioning, facilitate play and gross motor development
prognosis for SB
90% live to be adults
80% full intelligence
75% play sports
prevalence of ASD
1:44
4.2 times more in boys
why is there increased prevalence of ASD
earlier diagnosis
inc awareness
changes in screening
components of diagnostic and statistical manual of mental disorders
persistent deficits in social communication and social interaction across multi contexts
restricted, repeat patterns of behavior, interests/ activities
symptoms present in early development
symptoms cause clinically significant impairment in social, occupational, or other areas of function
disturbances not better explained by intellectual disability or global development delay
3 levels of ASD
level 3: requires very substantial support
level 2: requires substantial support
level 1: requires support
co-occuring conditions with ASD
adhd, communication disorders, epilepsy, GI disorders, intellectual disability, motor planning, dyspraxia, obesity, sleep disorders, toe walking
early detection of ASD
decreased social play
loss of words/ sentences
self injurious / repeat behaviors
sleep difficulties
special skills
seizures
intellectual diability
major concerns for ASD by 12 months
no babbling
no pointing
loss of language or social concerns
