ABSTRACT
Vomiting and diarrhoea is a common presenting complaint in paediatrics. Most often it is due to a benign and self-limiting infectious illness. Here, we explore the diagnostic journey of a 7-month-old infant with these symptoms presenting in a secondary care hospital and the overnight clinical problem solving involved in tackling the unexpected complexities.

Barium titanate (BaTiO3; BTO) is ferroelectric and piezoelectric after poling treatment. In this study, the bioactivity of BTO was investigated after a poling treatment by examining the formation of crystal growth on specimen surfaces in vitro. Negatively charged BTO surfaces showed calcium phosphate (Ca-P) crystal growth, while deposition of sodium chloride was observed on the positively charged BTO surfaces. After 30 days immersion in Eagle's MEM, the thickness of Ca-P crystal on negatively charged BTO surfaces increased to 0.8-0.9 microm. These data indicate that incorporating selectively polarized BTO on implant surfaces is a promising means for improving the bioactivity of implant materials.
