This is the first of three articles exploring the aspects of clinical care for children with rare neurological disorders including uncertainties old and new. The disruptive technologies of genomic sequencing and advanced therapeutics such as gene-based therapies offer parents of children with severe but rare neurological conditions for the first-time unprecedented opportunities for 'precision medicine'. At the same time, the realities of limited genomic diagnostic yields and not infrequent detection of variants of uncertain significance, lack of natural history study data and management guidelines for individually rare neurogenetic conditions, means that high pre-genomic test expectations are all too often replaced by an accumulation of new uncertainties. This can add to the chronic traumatic stress experienced by many families but may also have under-recognised impacts for their clinicians, contributing to 'burn-out' and attendant negative psychosocial impacts. This first article aims to address how clinicians might manage the accumulation of uncertainties to be more helpful to patients and their families. Moreover, it seeks to address how clinicians can move forward providing compassionate care to their patients and a little more consideration for themselves. [ABSTRACT FROM AUTHOR]

This is the second of a three-part series that explores different aspects of uncertainty, certainty and hope in the context of providing clinical care for children with rare and life-limiting neurological disorders. When caring for families impacted by an overwhelming complex disorder in a child, complicated by threatening uncertainties and potentially more threatening certainties, clinicians utilise skills drawn from differing fields to make the load of information, and the emotional impact more manageable. The first article in this series addressed how clinicians might manage the 'accumulation of uncertainties' and to provide compassionate care not only to their patients, and their families, but also to themselves. This second paper delves into the less helpful aspects of 'certainty', including the associated losses and griefs endured by parents responding to threatening fears associated with their child's condition. In the extreme, disconnection and psychological isolation borne by parents can lead to a sense of hopelessness and desperation. Facing unwelcome certainties - clinicians and parents together - forms the basis of future trust and hope. Clinicians who share the field of trust with families and show commitment to helping parents, even when cure remains elusive, build a sense of hope. This is the sort of hopefulness that clinicians need to have and to offer as they share the journey with families. In this series, we seek to harness a shared approach to face unwelcome certainties and to kindle a sense of hope that is both credible and meaningful to the parents, family and clinician.

This is the third article of a three-part series and addresses how clinicians provide hopefulness meaningfully to families coping with life-limiting and quality of life impairing neurological conditions. The first two articles addressed the enormous challenges faced by carers and also explored the struggles of clinicians trying to provide relief and comfort. Can these families, and those helping clinically, legitimately hope? It is expectation that consolidates desire into a substantial hope that may motivate finding a way forward. Hope must be realistic and directed to something in particular and in someone in particular. Hope and despair are not monolithic but often travel together for both children, families and clinicians. Hope is not denial but a belief that there are positive possibilities. Finding what can be helpfully hoped for and what must be realistically despaired of, is the discerning struggle. Clinicians aim to change what we can and accept what we cannot. Acceptance and grief are arrived at slowly for carers and families. Similarly, clinicians struggle with the hopes of bringing meaningful solace and are supported by trusted colleagues who have shared the same experience. Clinicians strive to respond appropriately and effectively in a dynamic process based on trust, providing presence and compassion when cure is not possible. Clinicians help find the small doable things that foster hope and lessen isolation and abandonment, mindful of the limits of their medical expertise. Surprisingly these modest hopes and faltering acceptances often provide a different form of strength and comfort to sustain a family. [ABSTRACT FROM AUTHOR]

Aim: Chromosomal microarray (CMA) is an important diagnostic test for children with multiple congenital anomalies or certain developmental behavioural problems suggestive of an underlying genetic diagnosis. However, there are medical and ethical complexities to its use and few Australian policies to guide practice. We aimed to describe the current practice of Australian paediatricians in relation to CMA testing. We hypothesised that there are knowledge gaps in their use of CMA.Methods: Online survey completed between September 2015 and January 2016 by paediatricians in secondary care settings. Participants were members of the Australian Paediatric Research Network. One hundred and sixty five (43%) of 383 active members responded. Our main outcome measures comprised: (i) the indications for which paediatricians request CMA; (ii) their approach to consent; (iii) their interpretation of results; and (iv) their understanding of the impact on patient management.Results: A significant proportion of paediatricians (21-52%) did not regularly use CMA for conditions with established evidence of diagnostic yield. Paediatricians under-estimated the potential for CMA findings to alter patient management. There was wide variability in paediatricians' approach to consent, and low use of consent forms and fact sheets. Paediatricians reported difficulties interpreting CMA results, with high rates of referral to clinical genetics services.Conclusions: The reported practice of Australian paediatricians is not consistent with international standards on CMA. Australian practice could be improved by a standardised approach to ordering CMA, consenting patients and interpreting results. We provide resources for CMA ordering and make recommendations about preparation for next generation sequencing. [ABSTRACT FROM AUTHOR]

Chromosomal microarray or molecular karyotype has become the first-line genetic investigation for children with intellectual disability, autistic spectrum disorder or multiple congenital anomalies. Chromosomal microarray increases the detection rate of pathogenic chromosome imbalances including submicroscopic deletions or duplications in patients with undiagnosed intellectual disability to approximately 15% compared with 3% with conventional cytogenetics. This review article summarises the diagnostic technique and highlights the advantages and limitations of chromosomal microarray. Our aim is to assist clinicians in providing pretest counselling and with interpretation of the result. [ABSTRACT FROM AUTHOR]
