In March 2012, an article in The Straits Times entitled 'Freezing eggs could reverse falling birth rate' suggested that employing the latest oocyte cryopreservation techniques could both foster individual women's reproductive autonomy and impact Singapore's fertility rate, which in recent years has consistently been among the world's lowest. The article cited both local and international fertility specialists' approval of elective oocyte cryopreservation for young women wishing to protect their reproductive potential against ageing and as a potential antidote to the contemporary 'delay and defer' model of family-building. Later in 2012, the Ministry of Health announced a review of oocyte cryopreservation policy taking into account related medical, scientific and ethical issues, while the Singapore College of Obstetricians and Gynaecologists endorsed oocyte cryopreservation as an "important, safe and efficient technology". This paper outlines and analyses the arguments and empirical evidence used both to support and oppose offering elective oocyte cryopreservation as a routine fertility service, before concluding that this remains unjustifiable on the basis of insufficient evidence of its clinical efficacy and safety as regards either pregnancy rates or birth outcomes. If it is to be made available at all for these reasons in Singapore, it should be subjected to rigorous clinic-specific evaluation in accordance with accepted clinical and ethical norms.

INTRODUCTIONThis article aims to provide an overview of the epidemiology, medical and rehabilitation issues, current evidence for traumatic brain injury (TBI) rehabilitation, recent advances and emerging practices. Special TBI population groups will also be addressed.

MATERIALS AND METHODSWe included publications indexed in Medline and the Cochrane Database of Systemic Reviews from 1974 to 2006, relevant chapters in major rehabilitation texts and Physical Medicine and Rehabilitation Clinics of North America and accessed Internet publications.

RESULTSTBI has been implicated by the World Health Organisation to be a 21st century epidemic similar to malaria and HIV/AIDS, not restricted to the developed world. One third of patients may suffer severe TBI with long-term cognitive and behavioural disabilities. Injuries to the brain do not only damage the cerebrum but may give rise to a multisystem disorder due to associated injuries in 20% of cases, which can include complex neurological impairments, neuroendocrine and neuromedical complications. There is promising evidence of improved outcome and functional benefits with early induction into a transdisciplinary brain injury rehabilitation programme. However, TBI research is fraught with difficulties because of an intrinsically heterogeneous population due to age, injury severity and type, functional outcome measures and small samples. Recent advances in TBI rehabilitation include task-specific training of cognitive deficits, computer-aided cognitive remediation and visual-spatial and visual scanning techniques and body weight-supported treadmill training for motor deficits. In addition, special rehabilitation issues for mild TBI, TBI-related vegetative states, elderly and young TBI, ethical issues and local data will also be discussed.

INTRODUCTION: Childhood radiation exposure is a known risk factor for thyroid malignancy and dysfunction. However, local data are limited and there is no consensus on the modality and frequency of screening in this high-risk group. METHODS: Retrospective analysis study evaluating patients with childhood radiation exposure in 2006-2016 and minimum of 1-year follow-up. RESULTS: Of the 132 childhood cancer survivors in the study, thyroid malignancy was detected in 2 cases (1.5%) and thyroid nodules in 13 (9.8%). The earliest thyroid malignancy was detected 5 years post-radiotherapy via ultrasound. Of the 84 patients who had screening thyroid function test, 26 (31.0%) were detected with abnormal test results post-radiation, majority being subclinical hypothyroidism. CONCLUSION Regular screening via clinical examination for thyroid nodules should be performed at least annually. Where feasible and if resources permit, consideration should be given to using ultrasound for thyroid nodule(s) and malignancy screening at 5 years post-radiation therapy. Screening for thyroid dysfunction can be considered from 6-12 months post-radiotherapy.
