fibromatosis colli
muscle spasm following trauma
just trauma

Question 3

cause of torticollis(broad)

Muscular or Skeletal

Question 4

cause of torticollis skeletal

Answer 4

unilateral interfacetal dislocation UID
occipital condyle fracture
Atlanto -axial rotatory fixation 
cns related
subarachnoid hemorage

Question 5

Fibromatosis colli

Answer 5

rare but accounts for 80% of childhood torticollis
due to traumatic delivery &
positioning in utero- develops 2-3wks after birth

benign proliferation of fibous tissue into SCM lower 1/3

Question 6

Bezold’s abscees

Answer 6

complication of suppurative mastoiditis

Occurs when infection errodes the mastoid tip into the neck, forming an abscess — can result in torticollis*

Question 7

true or false

torticollis can be caused by Rheumatoid Arthritis

Answer 7

true

due to Pannus

Answer 11

brachycephaly

Question 12

Answer 13

slant head- Occipital plagiocephaly

Question 14

scaphocephaly

Answer 14

most common form of craniosynostosis; more common in males

premature closure of sagittal suture

Question 15

Trigonocephaly

Answer 15

premature closure of metopic suture

Question 16

turricephaly

Answer 16

premature closure of coronal suture

Question 17

Frontal plagiocephaly

Answer 17

2nd most common craniosynostosis

Question 18

Occipital Plagiocephaly

Answer 18

More common in immobile children

premature closure of lamboid suture on one side

Question 19

syndromic craniosynostosis

Answer 19

autosomal dominant linked to chromosome 10q

Question 20

FGFR

Answer 20

(fibroblast growth factors)important in angiogenis
related to craniosynostosis syndromes
binds to many receptors
will see too much bone formation

Question 21

FGFR1

Answer 21

pfieffer syndrome

Question 22

FGFR2

Answer 22

HOTTEST fibroblast gene for mutations:(learn 1 &3 easier)
crouzon syndrome
Apert Syndrome
Prieffer syndrome  
Jackson wies syndrom

Question 23

FGFR3

Answer 23

Achondroplasia

thanstophoric dysplasia

Question 24

primary craniosynotosis

Answer 24

abnormal biology of the suture causes premature suture closure- FGfR related craniosynotosis

Question 25

secondary craniosynotosis

Answer 25

suture biology is normal | but abnormal external forces result in premature suture closure

Question 26

crouzon sydrome

Answer 26

``` craniofacial dysostosis complete penetrance autosomal dominant 50%due to spontaneous mutations Due to mutation of FGFR-2gene =10q26* NO SYNDACTYLY or cervical fusion ``` class 3 , midface hypoplasia

Question 27

apert

Answer 27

autosomal dominant | FGFR2- gene 10q26

Question 28

Pfeiffer's syndrome

Answer 28

skull is prematurely fused and unable to grow normally -craniosynostosis Bulging wide set eyes due to shallow eyesockets FGFR-2 under developed mid face

Question 29

Muenke syndrom

Answer 29

phenmotypic overlap occurs with other disease intellect normal Characterized by coronal synostosis or macrocephaly

Question 30

jackson wiess syndrom

Answer 30

foot abnormalities and premature fusion of certain parts of the skull

Question 31

ventrolateral

Answer 31

early migration trunk neural crest cell.. they migrate into and through the anterior of half of each somite

Question 32

vagal and sacral neural crest generate what

Answer 32
