The influence of wound age on the risk of infection in simple lacerations repaired in the emergency department (ED) has not been well studied. It has traditionally been taught that there is a "golden period" beyond which lacerations are at higher risk of infection and therefore should not be closed primarily. The proposed cutoff for this golden period has been highly variable (3-24h in surgical textbooks). Our objective is to answer the following research question: are wounds closed via primary repair after the golden period at increased risk for infection? ⋯ The existing evidence does not support the existence of a golden period nor does it support the role of wound age on infection rate in simple lacerations.

Systemic hypotension is a well documented predictor of increased mortality following traumatic brain injury (TBI). Hypotension is traditionally defined as systolic blood pressure (SBP)<90 mmHg. Recent evidence defines hypotension by a higher SBP in injured (non-TBI) trauma patients. We hypothesize that hypotension threshold requires a higher SBP in isolated moderate to severe TBI. ⋯ Patients with isolated moderate to severe TBI should be considered hypotensive for SBP<110 mmHg. Further research should confirm this new definition of hypotension by correlation with indices of perfusion.

Preoperative estimation of tibial nail length--because size does matter.
Selecting the correct tibial nail length is essential for satisfactory outcomes. Nails that are inserted and are found to be of inappropriate length should be removed. Accurate preoperative nail estimation has the potential to reduce intra-operative errors, operative time and radiation exposure. ⋯ We found that radiological methods such as using an AP radiograph with known magnification and intra-operative radiographic ruler were able to predict nail length very accurately and we suggest that these measurements should be performed routinely. The guidewire technique was also effective but we recommend that it not be used in isolation as errors can occur. We found that anatomical measurements are not accurate for predicting tibial nail length.

Selective non-operative management of penetrating abdominal injury in Great Britain and Ireland: survey of practice.
The selective non-operative management of penetrating abdominal injury is gaining increasing acceptance. In Great Britain and Ireland, the management of trauma remains the responsibility of general surgeons. This study appraises the acceptance and utilisation of selective non-operative management strategies by British and Irish general surgeons, compared with trauma surgeons in the United States of America. ⋯ The selective non-operative management of abdominal stab wounds is generally accepted by British and Irish general surgeons. In contrast, few British and Irish surgeons are comfortable with non-operatively managing patients with abdominal gunshot wounds, reflecting both the rarity of this type of injury, and surgeons' training and experience. This proportion is unlikely to change until the management of torso trauma is recognised as a specialty, and services are concentrated in regional centres.
