Introduction/Aims: Risdiplam is the newest available treatment for patients with spinal muscular atrophy (SMA). There is little information on its use in adults. We present the clinical experience of adults with SMA treated with risdiplam through the Early Access to Medicines Scheme (EAMS) in Northern Ireland. Methods: All adults with Type 2 SMA attending the regional neuromuscular clinic were offered risdiplam treatment. Patients had assessments of respiratory function, the Epworth Sleepiness Scale (ESS), Quality of Life Measure for People with Slowly Progressive and Genetic Neuromuscular Disease (QOLM), and Egen Klassifikation 2 (EK2) every 3 mo and the Revised Upper Limb Module for SMA (RULM) at baseline and 6 mo. All assessments other than the RULM were carried out virtually. Results: Six of seven patients who were offered risdiplam consented to treatment through the EAMS (five female, one male, mean age 33.7 y). It was generally well tolerated other than skin photosensitivity in all patients. All patients remained on therapy at 9 mo. All reported meaningful improvements in overall strength, sense of wellbeing, and speech quality. There was no change in respiratory function, daytime hypersomnolence, or upper limb function (all p >.05). There was improvement in the QOLM (p =.027) and EK2 (p =.009). Discussion: Our study raises hopes that risdiplam may be efficacious in adults; however, more systematic studies in larger cohorts are needed before drawing any definitive conclusions. This study also demonstrated the feasibility of virtual assessments. [ABSTRACT FROM AUTHOR]

Objective: To describe age and time at key stages in the Duchenne muscular dystrophy (DMD) prediagnosis pathway at selected centres to identify opportunities for service improvement.Design: A multicentre retrospective national audit.Setting: Nine tertiary neuromuscular centres across the UK and Ireland. A prior single-centre UK audit of 20 patients with no DMD family history provided benchmark criteria.Patients: Patients with a definitive diagnosis of DMD documented within 3 years prior to December 2018 (n=122).Main Outcome Measures: Mean age (months) at four key stages in the DMD diagnostic pathway and mean time (months) of presentational and diagnostic delay, and time from first reported symptoms to definitive diagnosis. Type of symptoms was also recorded.Results: Overall, mean age at definitive diagnosis, age at first engagement with healthcare professional (HCP) and age at first reported symptoms were 53.9±29.7, 49.9±28.9 and 36.4±26.8 months, respectively. The presentational delay and time to diagnosis were 21.1 (±21.1) and 4.6 (±7.9) months, respectively. The mean time from first reported symptoms to definitive diagnosis was 24.2±20.9. The percentages of patients with motor and/or non-motor symptoms recorded were 88% (n=106/121) and 47% (n=57/121), respectively.Conclusions: Majority of data mirrored the benchmark audit. However, while the time to diagnosis was shorter, a presentational delay was observed. Failure to recognise early symptoms of DMD could be a contributing factor and represents an unmet need in the diagnosis pathway. Methods determining how to improve this need to be explored.

Creatine kinase (CK) remains an essential tool for assessment of muscular weakness and pain in children despite the advent of advanced diagnostic tests in this field. It is also useful in diagnosing and monitoring various other conditions. This article will explore the physiology of CK and clinical situations where the estimation of CK can help the clinicians' decision-making process with the diagnosis and management of these conditions. Some clinical scenarios are used to highlight how the tests can be used in different clinical situations. The role of CK as a biomarker of myocardial injury has been purposefully omitted in this article. [ABSTRACT FROM AUTHOR]

Spinocerebellar ataxia type 5 (SCA-5) is a predominantly slowly progressive adult onset ataxia. We describe a child with a presentation of ataxic cerebral palsy (CP) and developmental delay at 6 months of age. Genetic testing confirmed a c.812C>T p.(Thr271Ile) mutation within the SPTBN2 gene. Seven previous cases of infantile onset SCA-5 are reported in the literature, four of which had a CP presentation. Early onset of SCA-5 presents with ataxic CP and is a rare cause of cerebral palsy.

Purpose To evaluate adherence to prescribed antiepileptic drugs ( AEDs) in children with epilepsy using a combination of adherence-assessment methods. Methods A total of 100 children with epilepsy (≤17 years old) were recruited. Medication adherence was determined via parental and child self-reporting (≥9 years old), medication refill data from general practitioner ( GP) prescribing records, and via AED concentrations in dried blood spot ( DBS) samples obtained from children at the clinic and via self- or parental-led sampling in children's own homes. The latter were assessed using population pharmacokinetic modeling. Patients were deemed nonadherent if any of these measures were indicative of nonadherence with the prescribed treatment. In addition, beliefs about medicines, parental confidence in seizure management, and the presence of depressed mood in parents were evaluated to examine their association with nonadherence in the participating children. Key Findings The overall rate of nonadherence in children with epilepsy was 33%. Logistic regression analysis indicated that children with generalized epilepsy (vs. focal epilepsy) were more likely (odds ratio [ OR] 4.7, 95% confidence interval [ CI] 1.37-15.81) to be classified as nonadherent as were children whose parents have depressed mood ( OR 3.6, 95% CI 1.16-11.41). Significance This is the first study to apply the novel methodology of determining adherence via AED concentrations in clinic and home DBS samples. The present findings show that the latter, with further development, could be a useful approach to adherence assessment when combined with other measures including parent and child self-reporting. Seizure type and parental depressed mood were strongly predictive of nonadherence. [ABSTRACT FROM AUTHOR]

Sydenham's chorea (SC) is characterised by chorea, emotional lability and hypotonia. In this study, we investigated the incidence and clinical presentation of childhood SC in Ireland (years 2006-2014). Nineteen cases were diagnosed. Five patients had rheumatic fever. An increasing trend with an incidence of 0.23/100 000 is reported. As most referral diagnoses included psychogenic illness, head injury and stroke, modern physicians may not be aware of this age old illness. A review of the manifestations and diagnosis of SC is presented. [ABSTRACT FROM AUTHOR]
