Q

unable to walk by 18 months?

A
  • CK  a small number of children may have a form of muscular dystrophy
  • Most will go on to walk but that is the time when we want to pick up diseases asap

Q

do children usually catch up with the delay in global developmental delay?

A

i. They say that children usually catch up, but it later on it increases the gap btw them and a child with a normal IQ
ii. 6 months delay/ 2 years  roughly 6 year level at 8 y/o, and 12 year level at 16 y/o
iii. The gap widens and many a times the kids won’t be able to live independently

25
what are the 21 features of trisomy 21 (Down's syndrome)
Mental impairment Abnormal teeth Stunted growth Slanted eyes ``` Umbilical hernia Shortened hands Increased skin on back of neck Short neck Low muscle tone Obstructive sleep apnea ``` Narrow roof of mouth Bent fifth finger tip Flat head Brushfield spots in the iris Flexible ligaments Single transverse palmar crease Proportionally large tongue Protruding tongue Abnormal outer ears Congenital heart disease Flattened nose Strabismus Separation of first and second toes Undescended testicles
26
what are the medical screenings that should be done for Down's syndrome?
i. Cardiac ii. Vision  hard to accommodate vision iii. Hearing (Brachycephaly  increased middle ear effusions) iv. Thyroid function  common under active thyroid v. Sleep related breathing disorders  sleep apnoea vi. Growth- charts  different growth patterns, height tends to be shorter and they tend to put on more weight vii. Development
27
what is a motor delay in children?
Duchenne Muscular Dystrophy, Cerebral Palsy, Co-ordination disorders
28
what is a language delay in children?
specific language impairment
29
what is a sensory deficit and associated delay in children?
Oculocutaneous Albinism, Treacher-Collins
30
what is a developmental deviation in children?
autism spectrum disorders
31
what are the features of Duchenne muscular dystrophy?
i. X-linked disorder ii. Mother is usually a carrier (50/50 chance of affecting the boy child) iii. Carriers usually have a little bit delay in walking but nothing much iv. Highly accentuated lordosis v. Pseudohypertrophy of the calves (muscle replaced by fibrous tissue so they are still weak) vi. Weakness of pelvic muscles **presents with Gower’s manoeuvre vii. Speech and language delay viii. Can develop associated respiratory and cardiac problems
32
what maneuver do children with DMD present with?
Gower's manoeuvre. | also present in any disease that causes pelvic weakness
33
what are the conditions associated with cerebral palsy?
``` diplegia hemiplagia quadriplegia epilepsy visual/hearing impairment communication difficulties feeding difficulties sleep problems behavior problems hearing loss visual loss increased tightness of muscle groups ```
34
what determines what conditions a child with cerebral palsy will have?
depends on which side of the brain are affected - children born pre-mature usually always have problems with visual tracts such a lower visual tract defects
35
what is needed when there is increased tightness of muscle groups as those with CP grow older?
physiotherapy
36
what may be different in delivering babies that are affected by CP?
may be difficult to deliver these babies (as there has been damage done antenatally and are born that way)
37
diplegia
22-33 weeks of pregnancy, big placental abruption, interruption of blood shed to the water shed areas of the brain at crucial areas, walk on tiptoes so increased risk of falling
38
between hemiplegia and quadriplegia which one is less common?
hemiplegia | quadriplegia - highest effect, worst prognosis
39
CP
is not a progressive condition
40
which type of cerebral palsy affects 22-33 weeks of pregnancy, big placental abruption, interruption of blood shed to the watershed areas of the brain at crucial areas?
diplegia
41
what is spastic diplegia?
protected from learning problems
42
what are sleep problems that people with CP have?
* Normal circulating levels of melatonin not in the right amount in these children * Silent reflux  due to co-ordination difficulties * Bad dental decay
43
what are behavior problems that people with CP have?
Abused | Poor communication skills
44
what are hearing loss problems do people with CP get?
bilateral middle ear effusions, blocked, sticky ears, sounds like you are under water and miss out a lot of high frequency sounds Sensory neuro
45
what is affected in oculocutaneous albinism?
i. Blonde skin ii. Blonde hair iii. Can see right back to the retina (as the iris isn’t coloured) iv. Involuntary to movement v. Photophobia vi. May have nystagmus vii. Hearing ipairment
46
what are the causes of hearing impairments in those with oculocutaneous albinism
i. bilateral middle ear effusions, blocked, sticky ears, sounds like you are under water and miss out a lot of high frequency sounds ii. sensory neuro
47
what is the autistic trio?
i. Communication ii. Social interaction iii. Flexibility of thought/ Imagination iv. Restricted, repetitive behaviours v. Sensory difficulties
48
what are the differences in the language variations in ASD communication?
receptive language expressive language non-verbal language use of language
49
receptive language
* Delayed * Expressive>Receptive * Abstract language difficult * Visually more able
50
expressive language
* Can appear Delayed * Echoes  repeating what they have just heard, or actually delayed  so it might look like they are coming up with something new but tbh they are just repeating it * Odd intonation/pitch  not spontaneous * Chunks of video speak * Non-verbal signs are affected
51
non-verbal language
* Facial expressions, gesture * Eye contact * Recognising intention of others
52
use of language
* Initiating and sustaining conversation * Restricted interests * Lack of awareness of reciprocal nature of conversation  they usually just keep going and don’t stop talking * They don’t know that they have to ask to get something
53
difference in girls vs boys?
i. Girls  neurotypical, its something that their peers are talking about and they a lot about it but don’t know what else to talk about ii. Boys  stuck with Thomas engine
54
how does ASD affect social interaction?
i. Joint Attention and Referencing • Trying to turn their attention to what you want ii. Turn taking • Very hard to get them to wait for others • Keep control as much as they can iii. Unable to share pleasure iv. Not motivated by need for social approval v. Social rules - don’t always follow it vi. Empathy – can’t empathise with their own emotions, so extremely difficult to relate to others vii. Relationships viii. Others point of view/feelings
55
what are the flexibility/thoughts/imagination in ASD?
i. Theory of mind – have a box with smarties cover in it but they only have pencil, and they think that everyone should know it ii. Concrete and lateral – eg: told that they should cut out crisps from him diet but he thought they were literally going to cut him open iii. Concept of time iv. Routines v. Changes in environment • Some may notice very tiny changes in the environment • Line up cars and objects according to size and shape and they want to put it back vi. Ritualistic behaviour • Carry around certain objects
56
what are sensory issues associated with ASD?
i. Fussy eater/ medications ii. Textures of clothes iii. Sleep iv. Toilet training – big issues v. Hair washing / cutting – they will scream but will have a problem when they are not in control vi. Nail cutting vii. Noise • May be over/ under sensitive – a big bag may calm them and stuffing themselves in small places
57
what is the approach to developmental delay?
i. History ii. Exam iii. Investigations iv. Assessments
58
how to identify developmental delay in neonatal?
odd behavior, won't eat, won't respond to sound
59
how to identify developmental delay in infants?
are they achieving their milestones, are they developing their language
60
pregnancy and developmental delay
did mom smoke/alcohol infections?
61
environmental and developmental delay
post natal depression/environmental problem, meningitis, post injury
62
what are the investigations of developmental delay?
i. Chromosomes, FRAX (fragile x) & Oligoarray CGH ii. Neonatal PKU, thyroid studies, CK iii. If indicated: - MRI brain 9only in indicated - EEG (only is eizures) - Metabolic studies (intervurrent illness) - Genetic consultation (conasngruant parents) - Others (hypertonic or not)
63
what are the various developmental assessments done?
MDT appropriate assessment tool always start with immediate early intervention without waiting for the results to come back other things to help make the environmental conditions better - realistic approach
64
immediate early interventions:
``` o Therapy o Physio o SLT o OT o Family Support o Educational Placement o Referral to Other Agencies ```
65
``` appropriate assessment tools: for the ages: 0-3 0-5 0-8 ASD ```
