Definitions of Disability

(WHO 2001)
Mental impairment and learning disability
– Intellectual impairment
• Mild / moderate / severe / profound
• (IQ levels 50-69/35-49/20-34/>20) WHO 2001 Mental Health
– Learning disability
• Denotes the presence of lower than normal intelligence
(IQ) (review for genetic association – ? syndrome)
– Specific Learning disability
• Low intelligence/normal intelligence/high intelligence
• ‘dyslexia’ (reading/writing/maths/ comprehension)
• Developmental Coordination Disorder (DCD)

Child Groups Definition

Infancy
(learning to trust/ vital bonding)

Toddler
( ability to control their bodies)

Early childhood

Middle childhood ( sense of competence)

Adolescence
(strong imagination)
(rapid physical and
emotional changes )
Greatest risk by hospitalization

Family Centred Care
based on principles
Make Rights and well being of child your priority
View Parents key to child’s health & well being
View parents as experts for their child
Support parents as individuals
Facilitate access to supports
Build on what is there
Develop a partnership approach
Work on interagency & interdepartmental basis
Plan in a locally responsive way

2009
Trust
Past experiences – borrow everyone's
“Tricks of the Trade”
Games (age/ability appropriate)
Flexibility (each child is an individual)
Choice (limit them to two)
Parents (collaboration)
Child (centre of the paediatric practice)

Delivering the news
“…and it’s not just a sentence, every word is
important because you are hanging on to
everything they say and you will
remember every word that they say, it
sticks in your mind. They need to really
plan their sentences and their words
because this is going to stay with you for
the rest of your life.”

Informing Families
“ It’s the toughest part of the job really.
When you have experience you will
prioritise this, because it’s a big
priority, because it’s something that
parents remember”

Types of Down Syndrome
Types of Down Syndrome
– Trisomy 21 (95%)
• Three chromosomes 21 in every cell
– Translocation (3-5%)
• Extra part of chromosome 21 attaches to
another chromosome in every cell
– Mosaic 1-2 %

chromosome 21 and others with just two.

disease in DS is necessary
 Undiagnosed hypothyroidism may result in
– preventable secondary handicap







Common in DS >50% require glasses

Prevents Unnecessary secondary
handicap

Speech & Language Problems







Speech impairment common
Receptive lanquage skills increased
Expressive language skills decreased
Linguistic area easier (vocabulary)
Grammar more difficult
No speech and Language problems unique to
children with DS.
Linked to hearing impairment (otitis media with
effusion, or fluid in the middle ear without signs
or symptoms of ear infection)
2009
Dr. J. Murphy, Paediatrics, TCD
44
Epilepsy in Down Syndrome

Why do people with DS develop Epilepsy?
o Brains are smaller and more spherical
o Hypoplasia of frontal and temporal lobes
o Microscopic: altered structure of cerebral cortex
 Frequency
– Down syndrome 5-10%
– General population 0.5-1%

Types of epilepsy
o Infantile Epilepsy (< 1 year age)
o Late Epilepsy
(grand mal 8-10%)
o Reflex Epilepsy (fits triggered by startle reaction)
2009
Dr. J. Murphy, Paediatrics, TCD
45
Practical management Epilepsy
Knowledge  anxieties  confidence
Treatment – common standards
Respect risks (traffic, water)
No unnecessary restrictions
Normally a favourable prognosis
2009
Dr. J. Murphy, Paediatrics, TCD
46
Leukaemia in DS

Newborns – Transient leukaemia
– Condition resembles leukaemia but disappears on its own
without treatment in a few weeks or months
– ? Increased of developing leukaemia in later life
Acute Myelocytic Leukaemia – common in first 3
years of life
 Acute Lymphocytic Leukaemia – after age 3 yrs
 Treatment of AML – children with DS respond better
than children without DS
 Treatment of ALL – response rate appears to be equal
 Of those with DS who develop Leukaemia

– 80% ALL and 20% AML
2009
Dr. J. Murphy, Paediatrics, TCD
47
Klinefelter syndrome in DS





Boys with DS have an extra X chromosome
(1/100)
Relatively small testes
Will not undergo normal body development
during adolescence
Infertility
May require treatment with male sex
hormone to develop the normal physical
changes of puberty
2009
Dr. J. Murphy, Paediatrics, TCD
48
Management in DS
Provide Accurate information
 Breaking the news/diagnosis

– Say this in a positive way
Remember Your first words to a family
have a Lifelong Impact
 Be the first step on the ladder to help
them achieve the positive adjustments
needed in their lives
 Focus on what can be done

2009
Dr. J. Murphy, Paediatrics, TCD
49
How You can Help
Always use the child’s name
 Look at Mam and Dad when
communicating
 Empathy - Try to understand what it
means to have a child with Down
syndrome or any disability
 Listen to and learn from parents

2009
Dr. J. Murphy, Paediatrics, TCD
50
Parents
Emotional time
 Take care of themselves
 Difficult for couples to help each other

– Both coming to this with their own history and
value system
– Protecting each other may make it difficult to
express their true feelings
It’s OK if they don’t feel those feelings
 It’s the ‘Down Syndrome’ that they are
having the problem with --Not their baby

Guidelines for using Growth Charts
Preterm babies



Insufficient data to compile preterm centiles
If < 37 weeks do no plot until reach EDD, and adjust for
prematurity for first year
If > 37 weeks plot as for chronological age
Underweight

Babies below 2nd centile likely to have significant feeding
difficulties or pathology and need further assessment
Overweight



Charts reflect the level of obesity in the current population NOT
the standard to be aimed for
If weight >75th centile calculate and chart BMI
If weight >98th centile on BMI needs further assessment
