Growth and Development Flashcards
What do we measure for growth in children?
- Height
- Length
- Sitting height
- Head circumference
Growth charts (later)
- LATER
How do we stage puberty?
- Tanner method
What is important in history and examination when establishing growth and development?
- Birth weight and gestation
- Past medical history
- Family history/ social history/ schooling
- Systematic enquiry
- Dysmorphic features
- Systemic examination
What assessment tools do we use for growth???
What are the factors influencing height?
- Age
- Sex
- Race
- Nutrition
- Parental heights
- Puberty
- Skeletal maturity
- General health
- Chronic disease
- Specific growth disorders
A normal growth curve includes what 3 stages?
- Infantile
- Childhood
- Pubertal
The following changes occur in boys during puberty:
- Advanced changes of puberty
- Faical hair and shaving
- Onset of testicular growth
- Penile growth
The following changes occur in girls during puberty:
- Breast budding
- Early breast development
- Menarche
Label these on the diagram below:
What are the most important pubertal stages in:
(a) A girl
(b) A boy
(a) Breast budding (Tanner Stage B2)
(b) Testicular enlargement (Tanner Stage G2 T3-4ml)
Which growth disorders would be an indication for referral
Growth disorders: Indications for referral:
- Height below target height
- Abnormal height velocity (crossing centiles)
- Extreme short or tall stature (off centile)
- History of chronic disease
- Obvious dysmorphic syndrome
- Early/ late puberty
State the ages of both early and delayed puberty in:
(a) Boys
(b) Girls
Early and delayed puberty:
(a) Boys: early < 9 years, delayed > 14 years
(b) Girls: Early < 8 years, delayed > 13 years
Constitutional Delay of Growth and Puberty (CDGP):
(a) Who is mainly affected
(b) What part of the history is important
(c) What is the cause
Constitutional delay of bone growth
(a) Mainly occurs in boys
(b) With a family history in the dad or brothers
(c) This occurs due to bone age delay
State some causes of delayed puberty
Causes of delayed puberty:
- Gonadal dysgenesis (Turner 45X, Klinefelter 47XXY)
- Chronic disease (Crohn’s, asthma)
- Kallman’s syndrome
- Cryptochidism (one of both testes fail to descend from the abdomen into the scrotum)
What are the causes of early breast development?
Causes of early breast development:
- Infantile thelarche
- Premature thelarche (thelarche = onset of secondary breast development. This should occur at the beginning of puberty)
- True central precocious puberty (condition that causes early sexual development in children)
