Question 1/4
According to international consensus guideline recommendations, which of the following referrals should be scheduled as a priority in the first year of life for neonates with achondroplasia?
Correct

International consensus guidelines on the management of achondroplasia highlight that in the first year of life, many clinics specializing in the management of skeletal dysplasias perform neuroradiological evaluation by MRI, as well as sleep studies, to screen for foramen magnum stenosis that may lead to cervicomedullary compression. Close monitoring with MRI and sleep studies are recommended at least up to the age of 3 years, as clinical suspicion remains even in the absence of findings. 

Abbreviation
MRI, magnetic resonance imaging.

Question 2/4
You are discussing the management of skeletal dysplasias with a new resident physician on your team. They ask you how best to support outcomes for people living with achondroplasia. Based on international consensus guidelines, which one of these key factors would you highlight to your colleague?

MDT, multidisciplinary team.
Correct

Recommendation 25 of the current international consensus guidelines on the management of achondroplasia state that all children with achondroplasia should receive regular follow-up with a multidisciplinary team led by a healthcare professional with expertise in achondroplasia. Furthermore, close monitoring in the first 2 years of life is highlighted as particularly important.

Reference
Savarirayan R, et al. Nat Rev Endocrinol. 2022;18:173–89

Question 3/4
You are managing a 6-year-old girl with achondroplasia. At her latest follow-up appointment, her parents tell you that their general practitioner/family physician informed them that their daughter is obese, based on BMI calculations performed in the clinic. What would you consider next in the management of this child?

BMI, body mass index.
Correct

International consensus guidelines on the management of achondroplasia recommend that parents of infants with achondroplasia should be provided with specific charts and a growth parameters register (height, weight and head circumference) for management follow-up.1 Due to the combination of extreme short legs and a near-normal trunk length, BMI values can become greatly distorted in achondroplasia populations when average stature charts and measures are used. The perception of being overweight and obese might, therefore, be increased in people with achondroplasia compared with people of normal stature. To address this, achondroplasia-specific charts and measures have been developed.2

Abbreviation
BMI, body mass index.

Question 4/4
Which of these is the most important patient characteristic to consider when determining suitability for achondroplasia pharmacotherapy to best support clinical outcomes?

FGFR3, fibroblast growth factor 3.
Correct

Indications for approved pharmacotherapies to manage achondroplasia in paediatric patients (USA) and children aged >4 months (Europe) require ongoing bone growth by confirming the presence of open epiphyses.1,2 Trials evaluating novel C-natriuretic peptide analogues have been conducted in prepubertal cohorts prior to epiphyseal closure, excluding participants with injury or disease that may affect the epiphyses.3,4
