2023 clinical practice guidelines on autism spectrum disorder in children and adolescents in Singapore.

Introduction: Autism is a neurodevelopmental condition that is increasing in prevalence worldwide. There has been an exponential increase in autism-related research since 2010, when the first Singapore Clinical Practice Guidelines (CPG) on autism was published. Understanding of autism has since evolved to adopt a lifespan approach beyond that of a childhood condition. The aim of this CPG was to provide an updated set of recommendations for children and adolescents to aid clinical practice for professionals. Method: A multidisciplinary workgroup that comprised representatives from various sectors worked on this CPG. Clinical questions were organised into 10 different sections, each with its own subgroup of members. Seventeen existing international guidelines were evaluated using the Appraisal of Guidelines for REsearch & Evaluation II (AGREE-II) framework, of which 4 met criteria to act as references. Literature review across multiple databases was conducted between January 2011 to 2023; Grading of Recommendations, Assessment, Development and Evaluation (GRADE-like) methodology was used to synthesise evidence. Recommendation statements were derived, following Delphi-style consensus surveys among the workgroup. The draft guidelines underwent external review and public consultation before being formalised. Results: Recommendation and good practice statements pertaining to care of children and adolescents on the autism spectrum across 10 different sections were developed. Evidence matrices complement these recommendations and detail relevant evidence behind each recommendation statement. Conclusion: It is intended for these guidelines to promote effective management and healthcare services for children and adolescents on the autism spectrum, by reinforcing good and evidence-based clinical practice within our national context.

The Routines-Based Model Internationally Implemented.

Professionals from 10 countries are implementing practices from the Routines-Based Model, which has three main components: needs assessment and intervention planning, a consultative approach, and a method for running classrooms. Its hallmark practices are the Routines-Based Interview, support-based visits with families, and a focus on child engagement. Implementers were interested in actual practices for putting philosophy and theory into action in their systems and cultures. We describe implementation challenges and successes and conclude that (a) models have to be adaptable, (b) some principles and practices are indeed universal, (c) we can shape excellent practices for international use, and (d) leadership is vital.

SARS in Singapore--predictors of disease severity.

INTRODUCTION: Severe acute respiratory syndrome (SARS) affected 8096 individuals in 29 countries, with 774 deaths. In Singapore, there were 238 cases of SARS with 33 deaths. A retrospective analysis was performed to identify predictors of poor outcome in patients with SARS locally. MATERIALS AND METHODS: Clinical, laboratory and outcome data of 234 patients admitted to Tan Tock Seng Hospital and Singapore General Hospital were collected and analysed. Only data collected at the time of admission were used in the analysis for predictors of poor outcome. Adverse events were defined as admission to the intensive care unit or death. RESULTS: Clinical (temperature, FiO2) and laboratory [leukocyte, lymphocyte, neutrophil, platelet, lactate dehydrogenase (LDH), albumin] trends in groups with and without an adversarial event were presented. Fifty patients experienced an adverse event. On univariate analysis, male gender, advanced age, presence of comorbidities, neutrophilia, lymphopaenia, hyponatraemia, hypoalbuminaemia, transaminitis and elevated LDH or C-reactive protein were found to be significant predictors. On multivariate analysis, predictors of poor outcome were increased age [odds ratio (OR) 1.73 for every 10-year increase; 95% CI, 1.35 to 2.21], neutrophilia (OR 1.06 for every 1 x 10(9)/L increase; 95% CI, 1.02 to 1.11) and high LDH (OR 1.17 for every 100 U/L increase; 95% CI, 1.02 to 1.34). None of the 12 paediatric patients had an adverse event. CONCLUSION: Advanced age, neutrophilia and high LDH predict poor outcomes in patients with SARS.

The clinical utility of the modified checklist for autism in toddlers with high risk 18-48 month old children in Singapore.

The modified checklist for autism in toddlers (M-CHAT) is a tool developed for 16-30 month old children to screen for autism spectrum disorders (ASD). It is a well-researched tool, but little is known about its utility with Singaporean toddlers and with older children referred for developmental concerns. This study investigated the M-CHAT's performance with 18-30 month old (N = 173) and >30-48 month old (N = 407) developmentally at-risk Singaporean children, when used with three recommended scoring methods i.e., the total, critical and Best7 scoring methods. The results indicate that the critical and Best7 scoring methods detected most true cases of ASD without inflating the false positive rates in toddlers, and that only the total scoring method performed acceptably for the older children.

SARS--my personal battle.

It isn't every day that a doctor becomes a patient. It is more peculiar when it occurs with an unknown mysterious epidemic respiratory illness that kills. Severe acute respiratory syndrome (SARS) gripped the world in 2003, spreading via air-links and throwing the global economy into disarray. As a practicing physician in Singapore, one of the first countries affected, I describe my first-hand account of my battle with this illness, how I acquired this illness in Singapore, and eventually quarantine in Frankfurt am Main, Germany.
