Comparative StudyAre we getting necrotizing soft tissue infections right? A 10-year review.
The Alfred Hospital is a referral centre for necrotizing soft tissue infections (NSTIs) in the state of Victoria and receives around 20 such patients each year. We sought to compare our practice and outcomes against published data, and to examine management at referring hospitals to determine whether adjustments to current practices are required. ⋯ NSTIs remain a surgical emergency with high rates of mortality and resource requirements. The mortality rate at our institution compares well with other published series. Many patients experienced delays before undergoing debridement and in many cases were transferred without debridement. The trend towards transferring NSTI patients to centres accustomed to treating burns and major trauma seems logical, but should not delay life-saving surgical debridement. Timing of transfer does not seem to affect mortality.

Comparative StudyIncidence and outcomes of major trauma patients managed in the Australian Capital Territory.
To determine the incidence and characteristics of major traumatic injury treated in the Australian Capital Territory (ACT) over a 5-year period. ⋯ The largest demographic affected by major trauma in the ACT and surrounds is young people. Injury prevention should remain focused on road trauma but also target violence and high-risk recreation activities. Further investigation around the circumstances of major traumatic injury in young people is required. Funding and cross-border agreements should be reviewed to minimize financial disadvantage to the ACT.

Review Case ReportsFree distal volar forearm perforator flap: clinical application in digital reconstruction.
Soft tissue defects of the digits can be a challenging problem for the hand surgeon. For non-graftable defects, numerous local, regional and free flaps have been described for resurfacing, each with their own limitations - bulk, colour, texture mismatch, donor morbidity. Perforator flaps increasingly provide the optimal option for reconstruction of digital defects as they are thin, pliable and with low donor site morbidity. ⋯ Dorsal digital soft tissue reconstruction requires thin, pliable, ideally hairless and sensate skin. Most locoregional options are limited by the need for multi-stage surgery, bulk, limited reach or donor site morbidity. In our patient, the reconstructive requirements were met with preservation of the radial artery. While it requires microsurgical skill and instruments, this flap provides another option for the reconstructive hand surgeon.

ReviewNuclear reprogramming and induced pluripotent stem cells: a review for surgeons.
Induced pluripotent stem cells (iPSCs) are generated from somatic cells by the exogenous expression of defined transcription factors. iPSCs share the defining features of embryonic stem cells (ESCs) in that they are able to self-renew indefinitely and maintain the potential to develop into all cell types of the body. These cells have key advantages over ESCs in that they are autologous to the donor cells and can be generated from individuals at any age. iPSCs also circumvent ethical and political issues surrounding the destruction of embryos that is necessary in the isolation of ESCs. This review briefly describes the advent of iPSC technology and the concepts of nuclear reprogramming, and discusses the potential application of this powerful biological tool in both surgical research and regenerative medicine.

Comparative StudyDenver screening protocol for blunt cerebrovascular injury reduces the use of multi-detector computed tomography angiography.
Blunt cerebrovascular injury (BCVI) occurs in 0.2-2.7% of blunt trauma patients and has up to 30% mortality. Conventional screening does not recognize up to 20% of BCVI patients. To improve diagnosis of BCVI, both an expanded battery of screening criteria and a multi-detector computed tomography angiography (CTA) have been suggested. The aim of this study is to investigate whether the use of CTA restricted to the Denver protocol screen-positive patients would reduce the unnecessary use of CTA as a pre-emptive screening tool. ⋯ Application of the CTA to the Denver protocol screen-positive trauma patients can decrease the use of CTA as a pre-emptive screening tool by 95-97% and reduces its hazards.
