This article discusses the important issue of the need for a stable definition of intellectual disability in order to allow comparisons by place and over time such as in the monitoring of this population's health needs and utilization. The aim of the new Australian National Centre for Intellectual Disability Health, established in 2023, is to ensure that all Australian children and adults with intellectual disability receive high-quality healthcare that meets their needs.
MECP2 duplication syndrome (MDS) is an ultrarare, X-linked neurodevelopmental disorder that is poorly understood in terms of its natural history and phenotypic variability. There is limited information on how individuals with MDS acquire, retain or lose fundamental functional skills (gross motor, purposeful hand function and communication) - that of which this study aimed to better characterise in the largest case series to date.
X-linked hypophosphatemia (XLH) is a rare, X-linked dominant condition with a high burden of both physical and psychosocial disease. This study aimed to describe the experience and burden of disease for children and adults living with XLH in Australia by inviting affected individuals and their carers to complete an online questionnaire. Of the 46 responses, half were completed by a person with XLH, and half by carers. Thirty percent were male, 33% were aged less than 18 yr.
Autosomal recessive hypophosphatemic rickets type 2 (ARHR2) and generalized arterial calcification of infancy (GACI) occur secondary to biallelic ectonucleotide pyrophosphate/phosphodiesterase 1 (ENPP1) loss-of-function pathogenic variants. GACI is a life-threatening condition, often presenting in the neonatal period with heart failure and hypertension, caused by calcification of the media in large- and medium-sized arteries.
It is now well accepted that germline or de novo genetic alterations predispose to cancer development, especially during childhood. Among them, constitutive trisomy 21, also known as Down syndrome (DS), has been shown to predispose to acute leukemia affecting both the myeloid (ML-DS) and lymphoid (DS-ALL) lineages. ML-DS is associated with a good prognosis compared to children without DS, due in part to a higher sensitivity to conventional chemotherapy.
This study aimed to (i) develop a decision tree to guide clinicians to use a core outcome set (COS) of chronic pain assessment tools specific to children and young people with cerebral palsy and (ii) pilot test the implementation of the decision tree and core set in clinical practice.
The clinical, research and advocacy communities for Rett syndrome are striving to achieve clinical trial readiness, including having fit-for-purpose clinical outcome assessments. This study aimed to (1) describe psychometric properties of clinical outcome assessment for Rett syndrome and (2) identify what is needed to ensure that fit-for-purpose clinical outcome assessments are available for clinical trials.
This study aims to describe the risk factors and trends in birth prevalence of septo-optic dysplasia (SOD) and gastroschisis between 1980 and 2023. This descriptive, population-based study of SOD and gastroschisis used Western Australian Register of Developmental Anomalies data from 1980 to 2023. Birth prevalence was calculated using Midwives Notification System data for all births after 20 weeks gestation.
Cerebral palsy (CP) should not be considered as a diagnosis but as a label; it is an umbrella term, primarily affecting posture and mobility. The definition is not sufficiently precise to guarantee agreement as to which patients to include under this label, but the additional inclusion criteria required are not yet internationally standardised.
Rett syndrome (RTT) is a severe neurodevelopmental disorder affecting predominantly females and associated with variants in the MECP2 gene. Recent success in clinical trials have resulted in an expanded use of the Rett Syndrome Behaviour Questionnaire (RSBQ) for clinical and research purposes.
