The prevalence of Autism Spectrum Disorder in Down Syndrome children attending the Child Development Centre in Universiti Kebangsaan Malaysia Medical Centre.

INTRODUCTION: The main objective of this study was to determine the prevalence of Autism Spectrum Disorder (ASD) in Down Syndrome (DS) children attending the DS clinic at Child Development Centre Universiti Kebangsaan Malaysia Medical Centre (CDC-UKMMC) and to assess the appropriateness of using an M-CHAT as an ASD screener in this population. We traced the karyotype results of our study population from their medical record and compared this to study participant with a dual diagnosis of Down Syndrome- Autism Spectrum Disorder (DS-ASD). Lastly, we assessed the awareness among parents attending our DS follow up clinic regarding the possibility of an ASD diagnosis in DS children. MATERIALS AND METHODS: This a single-centre cross-sectional study among DS children aged 18-60 months who attend the DS follow up clinic in UKMMC. Overall, 24 children were recruited to our study. The accompanying parent was given the Modified Checklist for Autism in Toddlers (M-CHAT) questionnaire and a data collection sheet prior to their consultation. The chromosomal study was traced from their medical case notes. Children that were eligible for the study had their development assessed using the tool Schedule of Growing Skills II. The diagnosis of ASD was determined by the attending paediatrician using The Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5) criteria. RESULTS: The prevalence of dual diagnoses DS-ASD in our study population was 4.2%. Using M-CHAT as a screener, 8 children failed the M-CHAT, of whom only one was diagnosed with ASD. None of the children that passed the MCHAT was diagnosed with ASD. Only 17 chromosomal study results were available for analysis, 2 children had mosaic DS whereas the remaining was caused by non-disjunction; the only DS-ASD patient had non-disjunction. Regarding parental awareness of dual diagnoses of ASD and DS, about 60% of the parents attending UKMMC clinic were aware of the possibility of ASD-DS diagnosis. CONCLUSIONS: Our results suggest that ASD prevalence in our DS study population is consistent with those previously reported, and that paediatricians managing DS children should be aware of the dual diagnoses of ASD and DS when managing these patients. Even though, we are unable to make a definitive conclusion regarding the use of M-CHAT in this population of children due to the very small sample size, possibly a multi-centre research in the future may help elucidate this issue.

Suicidal ideation among single, pregnant adolescents: The role of sexual and religious knowledge, attitudes and practices.

Pregnant adolescents are a high-risk population for suicide. However, a knowledge gap still exists on how sexual and religious knowledge, attitudes and practices (KAP) influence suicidal ideation (SI) in teenage pregnancy. We aim to explore the interplay between psychiatric diagnoses, sociodemographic factors and KAP of sexual and religious issues as risk factors of SI among 114 pregnant Malaysian adolescents from 6 rehabilitation centers and a tertiary hospital. Single sexual partner was an independent predictor of SI, suggesting the role of less sexual experience as a risk factor for SI after controlling for major depression. Participants who were unsure versus those who agreed with the statement that most religions' viewed sex outside marriage as wrong had a lower risk of SI after controlling for major depression. Pregnant adolescents with a single sexual partner were significantly associated with current SI. Ambivalence towards religious prohibitions on premarital sex may protect against suicidal ideation.

Spectrum of infections in splenectomised thalassaemia patients.

Splenectomised thalassaemia patients are at risk of developing sepsis. As the infection may be life-threatening, treatment should be sought and given promptly. A retrospective study was performed amongst our thalassaemia major patients who were splenectomised. The vaccination status of each patient and the types of infections seen were reviewed to obtain a local perspective. In our cohort of 49 splenectomised patients, 25 patients required hospitalization for the treatment of infection. There were a total of 40 febrile episodes within this hospitalised group of which 27.5% were microbiologically documented infection with bacteraemia. The predominant causative organisms were gram negative rods and three patients succumbed to overwhelming septicaemic shock as a result of delayed presentation. Sixty percent of the febrile episodes were clinically documented infection and comprised mainly upper respiratory tract infections. Based on the spectrum of infections seen, there is a need to improve the patients' awareness level so that early treatment is sought. There is also a need to re-address the approach towards vaccination in this immunocompromised group of patients by administering a booster pneumococcal and influenza vaccination in an attempt to reduce morbidity.
