growth assessment tools
height/length, weight growth charts + plotting MPH and target centiles growth velocity bone age pubertal assessment
growth disorders: indications for referral
- extreme short/tall stature (off centiles)
- height below target height
- abnormal height velocity (crossing centiles)
- hx chronic disease
- obvious dysmorphic syndrome
- early/late pubery
common causes of short stature
familial
constitutional
SGA/IUGR
growth investigaions
FBC + ferritin U&E, LFTs, Ca, CRP coeliac serology and IgA IGF-1, TFT, prolactin, cortisol karyotype/microarray
staging of puberty: tanner method
breast development
genital development
pubic hair
axillary hair
early and delayed puberty: boys
early <9yrs
delayed >14
early and delayed puberty: girls
early <8yrs
delayed >13
constitutional delay of growth and puberty
boys mainly
FH in dad or brothers
bone age delay
need to exclude organic disease
pathological causes of short stature
undernutrition chronic illness - IBD, coeliac iatrogenic - steroids psychological, social hormonal (GHD, hypothyroid, glucocorticoid excess) syndromes - Turner, P-W, Noonan, PHPT skeletal dysplasias
Turner syndrome: gene and who
45X0
girls
turner syndrome features
poor growth, short stature 1ry amenorrhea (ovarian dysgenesis) delayed/absent pubertal development webbed neck skeletal abnormalities congenital heart defects: aortic coarctation, bicuspid aortic valve
prader-willi syndrome genes
deletion of 15q11-q13 chromosome region
noonan’s syndrome features
autosomal dominant short stature abnormal facial features congenital heart defects: pulm valve stenosis chest deformities
causes of delayed puberty
chronic disease - Crohn’s, asthma
constitutional
primary gonadal disorders
impaired HPG axis
central precocious puberty
true pubertal development - breast development/testicular enlargement
growth spurt
advancing bone age
