1
Q

Phases of growth

A

Infancy – Nutrition and Insulin
Childhood – Growth hormone and Thyroxine
Puberty – Growth hormone and sex hormones
Consists of the acquisition of physical and intellectual skill and emotional balance

2
Q

Importance of Growth

A

An index and signal of health and well-being
Physical and psychological problems of being short
Intellectual benefits of improved growth

3
Q

Principles of Measuring growth

A

Define normal growth – growth charts and centiles

If abnormal growth is discovered – the aetiology should be investigated and treated

4
Q

What is Auxology?

A

a metaterm used to cover all measures of growth

Uses a standard technique with acceptable intra/inter observer error - also affordable and robust

5
Q

Measurements used to record growth

A

Weight - naked up to 2yrs, light clothes only after
Height
Length
Head Circumference (OFC)

6
Q

The four Factors required to growth

A

Health - pathologies and illness limit growth
Food - is there a restriction in nutrition?
Nurturing - is the neglect or abuse?
Hormones - at the right time and right amount?

7
Q

Describe Normal growth curves

A

Weight and height increase rapidly in the first 2yrs then steadily till 12-14 –> growth spurt (Boys:14, Girls:12) ending with boys being taller and heavier

8
Q

Which Factors effecting growth?

A
Gender is most important
Variation in families, populations and ethnicity
Social class has epi-genetic and nutritional features
9
Q

Explain Growth charts

A

A way of comparing an individuals growth with the average of a reference population
Divide into centiles - 0.4, 2, 9, 25, 50, 75, 91, 98, 99.6
Each band is 2/3 of SD

10
Q

Williams syndrome

A

Deletion of 26 genes from the long arm of chr 7 leading to small statue, low IQ but strong verbal scores, elfin appearance and being hyper social

11
Q

What types of Abnormal growth are there?

A

Can be specific - crossing centile lines– dropping two lines defines failure to thrive
Can be relational – abnormal height to weight or abnormal body proportions (legs and arms)

12
Q

Changes of BMI throughout childhood

A

Increases rapidly after birth to about 17/18 by age 1.
Then decreases to 15/16 through childhood and starts increasing again at age 8 for girls and 9 for boys – boys overtake girls at age 17/18

13
Q

Investigating small stature (History) (4x2)

A

Birth weight (IUGR/SGA) - Feeding and nutrition in infancy
Developmental syndromes - chronic or recent growth failure
Ethnic and FHx – pubertal development and mother’s age of menache
Social Hx - fostered/adopted?, neglect/abuse, low family IQ, poor nutrition

14
Q

Investigating small stature (Anthropometry) (5,5)

A

Short legs - hypothyroid, rickets, skeletal dysplasia, turner syn.
Short spine - scoliosis, irradiation, haemoglobinopathy, spinal anomaly, Severe emotional disturbance
Long legs - delayed puberty

15
Q

Causes of short, fat children

A

Mainly endocrine causes - hypothyridism, GH deficiency, Cushings

16
Q

Causes of short thin children

A

Chronic systemic diseases - cardiac, respiratory, renal, metabolic
Malabsorption - Coeliac disease or Crohn’s disease
Malnutrition, neglect or cerebral palsy

17
Q

Causes for low birth weight

A

Prematurity Chromosomal abnormality
Intrauterine infection Fetal alcohol syndrome
Silver-Russell syndrome (dwafism) Maternal/placental factors

18
Q

Features of underweight children with Coeliac disease (5)

A

Tiredness and anaemia
Positive antibodies (anti-endomysial/anti-gliadin) and jejunal biopsy
Will respond to diet
Strongly associated with HLA-DQ2 (95%) and HLA B8 (80%)

19
Q

What is Bone age?

A

Bones change during growth in a way which can be seen on X-ray – the bone age of a child is the average age children are when they get to the stage of maturation their bones are.
A child’s current height and bone age can be used to predict adult height

20
Q

Investigations of short stature

A

FBC, U+Es, Ca, P, ALP,
Thyroid function and GH stimulation tests (Insulin or arginine)
Coeliac antibody screen
Chromosome test and left hand and wrist X-ray to check bone age

21
Q

Turner’s syndrome

A

45X - short with an abnormal upper to lower body ratio.
60% have high palate and small jaw
Poss: cubitus valgus, short metacarpals, neck webbing, foot oedema.
Nearly all are infertile and half have heart problems, 40% have renal problems and 40% have thyroid dysfunction

22
Q

Delayed onset of puberty

A

Common in boys, not girls - Often familial & usually ‘constitutional’
Can be due to gonadotropin deficiency or gonadal failure
May be a sign of chromosomal issue (klinefelters syndrome)

23
Q

Management of short stature in children

A

Growth promoting agents - GH, oxandrolone or testosterone

Also consider nutritional or social interventions

24
Q

Classification of Growth hormone deficiency

A

Developmental –> isolated partial or total, multiple pituitary hormone deficiency
Secondary –> tumours, histocytosis X, mid-facial defects or septo-optic dysplasia

25
Q

Indications for GH treatment

A

GH deficiency –> Severe GH deficiency (isolated or multiple) or transient deficiency due to irradiation
Other –> turners syndrome, chronic renal insufficiency, Prader-willi syndrome, SGA

26
Q

Developmental domains

A

Gross motor
Fine Motor (eye-hand coordination)
Language & hearing (receptive and expressive)
Social development (behaviour and self help skills)
Cognitive development and special senses

27
Q

Factors affecting developmental outcomes

A

Genetic potential
Acquired pathology in utero, perinatal or infant
Environmental factors restricting potential – maternal health, mental health, SE status

28
Q

Definition of developmental delay

A

A failure in the acquisition of expected skills which leads to functional impairment for the child
‘Expected’ can refer timing or order
Impairment may be physical, social, communicative, emotional or academic

29
Q

Developmental progress in vision

A

Bright lights and faces at birth – attends to progressively smaller objects over the first year –> underpins fine motor abilities

30

43
Q

Distinguishing specific and global delay

A

Specific is a single area with is 2SD below the average IQ
Global is more than 2 areas where developmental age is less than actual age - if it is 50% or more of expected it is mild to moderate and >50% is severe
