Down’s syndrome occurs in 1:1000 live births and is the commonest identifiable cause of learning difficulties. There is a significant variability in appearance, personality and levels of general health and independence. Some medical problems are over-represented in people with Down’s syndrome and, for this reason, this group of children are followed up regularly by a team usually based in the local child development centre. In Waltham Forest the multidisciplinary Wood Street children’s specialist service team oversee the growth and development of the children with Down’s syndrome, ensuring their health needs are met and their potential for learning maximised.

I have asked the Wood Street team to add some comments and pathway information below…

Educational psychologists in Waltham forest
Our local educational psychologists are running drop in sessions on the 3rd Wednesday of every month at their base in Leyton, E10. The current flyer which includes contact details is here and sessions will be on-going in 2012 even if not listed here. They tell me that they would be happy to run EP drop in sessions or parent workshops/training/support groups at local GP surgeries and jointly with GPs or other medical colleagues – GPs are welcome to contact them to discuss. Their Urdu speaking colleague runs sessions in a local Mosque as well.
October’s Paediatric Pearls
October’s edition is joint again this month on account of my right radius being fractured and its being too difficult to type and format text boxes with just my left hand… I am obviously not quite as good at ice-skating as I thought I was. All the topics this month should be of interest to both the ED and primary care teams anyway: a paper on paediatric early warning scores, the start of our neurodevelopment series, an update on services for bereaved children and their families and some useful links on the subject of head-lice.
Age of walking
It is not uncommon for us to be referred not-yet-ambulant children just past the 18 month “upper limit of normal” age of walking. The majority of these children are using means other than crawling to get around. I had vague recollections of having seen a table once detailing the 97th centile for walking in children who bottom shuffle, commando crawl or roll everywhere but I spent 2 or 3 fruitless hours searching the literature for it a couple of months ago. So I was ironically excited this month to find that Archives of Disease in Childhood had reproduced it! One of our current registrars, Dr Amy Rogers, has kindly put together an article for Paediatric Pearls with nuggets from that paper (Sharma A Developmental Examination: Birth to 5 Years. Arch Dis Child Educ Pract Ed 2011;96:162-175 doi:10.1136/adc.2009.175901) which summarises normal development and when it would be prudent to refer children for further developmental assessment:
Approach to developmental assessment – birth to 1 year: Motor1
1) Elicit parental/carer concerns. Questions to ask:
- Do you have any concerns about the way your baby moves his arms/legs or body? Have you ever noticed any odd or unusual movements?
- Has your baby ever been too floppy or too stiff?
- Does your baby have a strong preference for one hand and ignore the other hand?
2) Gather information on social/biological risk factors:
Risk factors for poor developmental outcomes
Biological | Family and social |
Prenatal: drug/alcohol use, anti-epileptics, infection | Poverty, neglect, abuse, low maternal education, parental mental illness, inadequate parenting, disadvantaged neighborhood, absence of social support network |
Perinatal: Prematurity, low birth weight | |
Postnatal: Infection, severe hyperbilirubinaemia, injury, FTT, epilepsy |
3) Observe/elicit behavior and interpret findings
Note posture and movement. Examine tone. Elicit primary (Moro, grasp and asymmetrical tonic neck reflex) and support reflexes (downward, sideward and forward). Video clips of all these reflexes can be seen at http://library.med.utah.edu/pedineurologicexam/html/newborn_n.html.
What is not normal?
- Fisting of hands beyond 3 months
- Poor head control at 4 months
- Primitive reflexes beyond 6 months
- Flexor hypertonia in lower limbs beyond 9 months
- Not sitting unsupported with straight spine by 10 months
- Not walking by 18 months
BUT preterm infants often have delayed motor milestones, early hypotonia and longer lasting asymmetrical tonic neck reflex. Children with atypical pre-walking movement patterns (ie. non-crawlers) are late in achieving independent sitting and walking.
Pre-walking movement pattern and motor milestones (97th percentile)2
Movement pattern | Sitting (months) | Crawling (months) | Walking (months) |
Crawling | 12 | 13 | 18.5 |
None – stand and walk | 11.5 | 14.5 | |
Creeping/commando crawling | 13 | 15 | 30.5 |
Rolling | 13 | 14.5 | 24.5 |
Bottom Shuffling | 15 | 27 |
Refer if concerned as delayed motor development may be a marker for motor disorders and may have a negative impact on a child’s performance in the cognitive and social developmental domains. There is more information on delayed walking in a Patient Plus article written for health professionals available at http://www.patient.co.uk/doctor/Delay-In-Walking.htm.

FONTANELLES AND HEAD CIRCUMFERENCE AT SIX WEEK CHECK
with thanks to Dr Harriet Clompus.
Assessment of fontanelles is an important part of the six week check. Large fontanelles may indicate a problem in bone ossification or hydrocephaly, while a fused anterior fontanelle can indicate craniosynostosis. These need to be referred to paediatric outpatients. Always remember that anterior fontanelle size is very variable (1-4.7 cm in any direction) and always needs to be assessed in context of baby’s head circumference.
A sunken fontanelle indicates dehydration, while a bulging fontanelle indicates raised intracranial pressure (but can be non-pathological – vomiting, crying, coughing – so assess when baby settled!). These can be discussed with paediatric registrar on-call.
1) The anterior fontanelle is diamond shaped, 1-4.7 cm in any direction at birth (black infants larger than white) and can widen in first 2 months of life. Median age of closure is 14 months (4 – 24 months)
2) The posterior fontanelle is triangular and is less than 1 cm. It closes by 6 – 12 weeks.
3) The size of the fontanelles should always be assessed in conjunction with the head circumference.
- Macrocephaly – familial, hydrocephaly or skeletal disorders such as achondroplasia.
- Microcephaly – familial, congenital infections, fetal alcohol syndrome, trisomies
4) The quality of the fontanelle should always be assessed.
- Soft fontanelle – normal
- Bulging fontanelle – raised intracranial pressure (hydrocephalus, meningitis/encephalitis) . NB can be non-pathological in crying, coughing or vomiting infant.
- Sunken fontanelle – dehydration
1) WIDENED FONTANELLES: think of…
Achondroplasia
Downs
Hydrocephalus
IUGR
Prematurity
Congenital Rubella
Neonatal Hypothyroidism (3rd fontanelle)
Osteogenesis Imperfecta
Malnutrition
Rickets/Osteomalacia
Rickets – Think of rickets in darker skinned, breast fed babies, especially if mothers are veiled. Infants will often have sweating on the head. If widened sutures are found check neonatal blood spot for hypothyroidism and refer to outpatients.
Hydrocephalus – can have widened, bulging fontanelles in conjunction with a large head.
2) PREMATURE FUSION OF FONTANELLES AND CRANIOSYNOSTOSIS
Closure of anterior fontanelle by six weeks always pathological (NB by 3 months 1% of normal infants will have a closed anterior fontanelle).
Must always assess in conjunction with head circumference – early fusion associated with microcephaly (and less commonly, macrocephaly).
Craniosyntosis is premature closure of cranial suture(s) with skull growth restriction perpendicular to fused suture and compensatory skull overgrowth in unrestricted areas. Presents with ridging (always pathological beyond one week of life) and abnormal skull shape (usually later than six weeks).
There is a nice background overview (with useful diagrams) to craniosynostosis at http://www.cincinnatichildrens.org/health/info/neurology/diagnose/craniosynostosis.htm.
Primary craniosynostosis is due to abnormal ossification of one or more sutures. Simple – premature fusion of one suture, complex – premature fusion of multiple sutures. Causes include rickets, hyperparathyroidism, hyperthyroidism , idiopathic and genetic causes such as Aperts.
Secondary craniosynostosis is caused by premature closure of ALL sutures due to lack of primary brain growth. If you find a child with premature closure of fontanelles or over-riding sutures at six week check you should refer to paediatric outpatients. NB Plagiocephaly (flat occiput) is a non-pathological deformation due to ‘back to sleep’ position – no action required. It presents with ear on flattened side presenting anteriorly. Parallelogram shaped head (as opposed to lambdoid suture craniosynostosis trapezoid shaped)
The following articles give lots of information on fontanelles and/or sutures. The Fuloria article is very thorough and although it focuses on neonatal examination, most of it is still relevant for the six week check.

Neurological examination in babies
I have been looking at information on primitive reflexes as I was asked by a GP whether it was significant if he could not elicit a Moro reflex at the newborn check. Wikipedia has a nice description of the Moro reflex: “it may be observed in incomplete form in premature birth after the 28th week of gestation, and is usually present in complete form by week 34 (third trimester). It is normally present in all infants/newborns up to 4 or 5 months of age, and its absence indicates a profound disorder of the motor system. An absent or inadequate Moro response on one side is found in infants with hemiplegia, brachial plexus palsy, or a fractured clavicle”.
You need to make sure you are eliciting it correctly first though. I have found a great site from Utah university with little video clips of aspects of a normal and abnormal neurological examination of a 5 day old. Take a look at http://library.med.utah.edu/pedineurologicexam/html/newborn_n.html and watch the 2 Moro examples carefully. Did you know the hands have to come together in the mid-line at the end?
