Q

Fibromatosis colli

A

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

Q

Bezold’s abscees

A

complication of suppurative mastoiditis

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

A

2nd most common craniosynostosis

18
Q

Occipital Plagiocephaly

A

More common in immobile children

premature closure of lamboid suture on one side

19
Q

syndromic craniosynostosis

A

autosomal dominant linked to chromosome 10q

20
Q

FGFR

A

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

21
Q

FGFR1

A

pfieffer syndrome

22
Q

FGFR2

A 
HOTTEST fibroblast gene for mutations:(learn 1 &3 easier)
crouzon syndrome
Apert Syndrome
Prieffer syndrome  
Jackson wies syndrom
23
Q

FGFR3

A

Achondroplasia

thanstophoric dysplasia

24
Q

primary craniosynotosis

A

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

25
Q

secondary craniosynotosis

A

suture biology is normal

but abnormal external forces result in premature suture closure

26
Q

crouzon sydrome

A 
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

27
Q

apert

A

autosomal dominant

FGFR2- gene 10q26

28
Q

Pfeiffer’s syndrome

A

skull is prematurely fused and unable to grow normally -craniosynostosis

Muenke syndrom

A

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

30
Q

jackson wiess syndrom

A

foot abnormalities and premature fusion of certain parts of the skull

31
Q

ventrolateral

A

early migration trunk neural crest cell..

they migrate into and through the anterior of half of each somite

32
Q

vagal and sacral neural crest generate what

A

33
Q

Cardiac neural crest cells form

A

34
Q

where does heart form

A

ink neck under pharyngeal arches

35
Q

cranial(cephalic) neural crest cells

A

cells from craniotomy facial mesenchyme ;

creates facial cartilage and bone

36
