Pediatrics Flashcards
Rules of growth
Cont process, cephalocaudal, unique in each individual, each tiss- unique growth pattern
Weight doubles and triples by
5m, 1 yr
Height doubles by, and triples by
4y and 12 yrs
Hc at birth
33-34
Hc increased by
First 3m 2cm/month
4-6 1cm/m
6-12 0.5cm/m
Sequence of puberty in females
Telarche, pubarche, menarche
Sequence of puberty in males
Testicular enlargement, pubarche/pubical growth/manly changes
Best marker of pubertal status
LH and FSH
Taners staging for male
Grade 111
Coarsening and curling of pubic hair
Increased length of penis
Test vol -10 ml
Taners staging 4
Increase in penile width
Growth spurt(9-11cm/yr
Taners stage five for adult male
Tv >20 ml 25
Scrottal reddening ? Which stage
Scrottal darkening?? Which stage
Reddening-TS 2
Darkening -TS 4
Breast bud app

Short stature
H/A <-2 SD or 3rd centile
Short stature types
Physiological
Familial
Constitutional delay in growth and puberty
Pathological
Proportionate ss US:LS maintained
Dis proportionate US:LS not maintained
Familial short stature
<3rd centile
Equal to genetic pottential
Familial sd
Mph for boys
Ht(f)+ht(m)÷2+6.5
Familial ss for girls

In familial ss
Bone age=chronological age

Delay in puberty
Bone age<chronological age
Pathological short stature proportionate eg
Us:ls ratio maintained
Eg:malnutrition, ckd, torch, GH def, turner
Dispropotionate short stature 2 type

Torch inf ,Zika
Teratogens -eg alcohol
Inborn error of metabolism
neural tube defect
Structural anomaly
Causes of macrocephaly
Inc skull thickness - any chronic hemolytic anemia eg thalasemia
Accumulation of blood or pus+ hemorrhage
Hydrocephalus
Hydroencephaly
Lsd, leukodystrophism, NC dyndrome

Ataxia
Mild intellectual disability
Plagiocephaly
Abn flattening of one side of skull
Craniosynostosis
Premature sutural fusion
Craniosyntosis eg:
Dolichocephaly,brachycephaly,trigonocephaly,torrycephaly
