Diagnosis and Management of Iron Deficiency Anaemia in Children — A Clinical Update
Iron deficiency anaemia (IDA) remains an important public health problem even in developed countries like Singapore. This clinical update covers recent developments in the knowledge of iron metabolism, which aids in the approach towards the diagnosis, management and prevention of IDA in children. Besides IDA, iron deficiency (ID) has several non-haematological consequences including effects on neurocognition and immune function as suggested by several animal and clinical studies. Thus paediatricians and other health care providers should work towards the prevention and elimination of IDA in children
An Update on the Dental Management of Children with Haemophilia
Children with haemophilia present a bleeding risk and a challenge for dentists. Guidelines on the dental management of haemophilia patients are largely based on expert consensus. Many existing guidelines also provide generic guidance mainly for adult patients, which have been adapted for children. However, children have unique needs that require additional considerations. With limited evidence available, it is important that dentists have an understanding of the principles of both medical and dental management and have a close collaboration with the haematologist at all times. Therefore, this paper provides some key principles related to various aspects of dental management of children with haemophilia. Furthermore, there has been a recent update to the World Federation of Haemophilia (WFH) Guidelines for the Management of Haemophilia,1 with references to novel medical therapies for haemophilia. Hence, this paper also aims to inform dentists with the standard and newer medical therapies for haemophilia, including a specific focus on the novel agent Emicizumab and the associated dental considerations
Case 1: A Rare Case of Antenatal Hemorrhagic Stroke and Recurrent Purpura Fulminans in a Preterm Newborn
Comparison of perioperative practices for placement of central venous access devices (CVAD) in children with haemophilia
In children with haemophilia (CwH), central venous access devices (CVADs) are frequently placed to aid in the delivery of factor concentrates. In those who develop inhibitors, CVADs also allow for easy venous access and facilitation of immune tolerance therapy
Blood Lost: A Retrospective Review of Blood Wastage from a Massive Transfusion Protocol in a Tertiary Paediatric Hospital
Background: The paediatric massive transfusion protocol (MTP) is activated in the paediatric population for both trauma and non-trauma related indications. While it helps to improve the efficiency and efficacy of the delivery of blood products, it can also result in increased wastage. We aimed to evaluate the wastage rates from our paediatric MTP activations from 2013 to 2018. Method: As part of an audit, we retrospectively reviewed the records of the paediatric patients who had MTP activations. We collected the following data: reason for MTP activation, weight of patient, number of cycles of MTP required, blood products used, blood products wasted, deviation from our institution’s recommended MTP blood product ratio, and reason for wastage. Result: We had 26 paediatric MTP activations within the audit period. There was an overall wastage rate of 1.5%, with wastage occurring in 3 out of 26 patients. The reason for all wastage was demise of the patient. Most patients’ transfusion ratios deviated from our institution’s MTP protocol. Conclusion: Our wastage rates are low likely because of clear MTP activation guidelines and a flexible MTP workflow
Invasive paediatric Elizabethkingia meningoseptica infections are best treated with a combination of piperacillin/tazobactam and trimethoprim/sulfamethoxazole or fluoroquinolone
Objectives: Elizabethkingia meningoseptica is a multi-drug-resistant organism that is associated with high mortality and morbidity in newborn and immunocompromised patients. This study aimed to identify the best antimicrobial therapy for treating
this infection.
Methods: A retrospective descriptive study was conducted from 2010 to 2017 in a tertiary paediatric hospital in Singapore.
Paediatric patients aged 0 to 18years old with a positive culture for E. meningoseptica from any sterile site were identified from
the hospital laboratory database. The data collected included clinical characteristics, antimicrobial susceptibility and treatment,
and clinical outcomes.
Results: Thirteen cases were identified in this study. Combination therapy with piperacillin/tazobactam and trimethoprim/sulfamethoxazole or a fluoroquinolone resulted in a cure rate of 81.8 %. The mortality rate was 15.4 % and neurological morbidity
in patients with bacteraemia and meningitis remained high (75%).
Conclusions: Treatment with combination therapy of piperacillin/tazobactam and trimethoprim/sulfamethoxazole or a fluroquinolone was effective in this study, with low mortality rates being observed.Published versio

Genome-wide association meta-analysis highlights light-induced signaling as a driver for refractive error.
Refractive errors, including myopia, are the most frequent eye disorders worldwide and an increasingly common cause of blindness. This genome-wide association meta-analysis in 160,420 participants and replication in 95,505 participants increased the number of established independent signals from 37 to 161 and showed high genetic correlation between Europeans and Asians (>0.78). Expression experiments and comprehensive in silico analyses identified retinal cell physiology and light processing as prominent mechanisms, and also identified functional contributions to refractive-error development in all cell types of the neurosensory retina, retinal pigment epithelium, vascular endothelium and extracellular matrix. Newly identified genes implicate novel mechanisms such as rod-and-cone bipolar synaptic neurotransmission, anterior-segment morphology and angiogenesis. Thirty-one loci resided in or near regions transcribing small RNAs, thus suggesting a role for post-transcriptional regulation. Our results support the notion that refractive errors are caused by a light-dependent retina-to-sclera signaling cascade and delineate potential pathobiological molecular drivers
