To propose and evaluate a nomogram to assist paramedics to visually estimate the external blood loss on a non-absorbent surface and to identify whether the nomogram improves visual estimation. ⋯ The nomogram significantly improved the estimation of external blood loss volume.

To evaluate the efficacy (length of stay in the emergency department and failure rate of Bier's block) and safety profile (death and major complications) of Bier's block in its use for manipulation and reduction of paediatric forearm fractures. ⋯ Bier's block is a safe technique for reduction of fractures when used in the appropriate population and fracture types, with a low failure rate and no major complications including death. Compared to the ketamine group, it has a shorter length of stay in the emergency department. We recommend the adoption of this practice for manipulation and reduction of pediatric forearm fractures in the Emergency Department with a formalised protocol to reduce and prevent any human errors that can potentially result in complications.

Dementia and fragility fractures are two conditions that pose significant morbidity and mortality to the elderly population. The occurrence of the 'gerontic' boom as a result of improved healthcare meant a continued increase in the prevalence of fragility fractures and dementia. This represents a major public health problem with significant socioeconomic repercussions. ⋯ This alongside with a multidisciplinary approach will not only translate to improved patient outcomes and survivorship, but also reduced healthcare cost and socio-economic burden. To date, there is insufficient evidence from the literature to suggest whether dementia is the cause or effect for fragility fractures, or if indeed there is a bidirectional relationship between the two conditions. Further studies are required to shed light onto this important clinical topic.

Factors affecting the outcomes of modified tension band wiring techniques in transverse patellar fractures.
Modified tension band wiring has been widely used to treat transverse patellar fractures. However, few studies have evaluated the clinical outcomes using different methods of Kirschner wire bending, location of the tension band, and depths of Kirschner wires. Thus, we tried to clarify these factors according to our clinical outcomes. ⋯ The modified tension band technique for transverse patella fractures provides favourable clinical outcomes, with low failure (5%) and infection (2%) rates. Implant irritation is the major complication, and almost half of cases require implant removal. The location of the tension band with respect to the superior and inferior border of the patella plays an important role in clinical outcomes. Placing the wire close to the patella may prevent major loss of reduction and implant breakage. Superficially placed Kirschner wires also affect clinical outcomes by increasing the rate of minor loss of reduction.
