Observational StudyPredicting outcomes in patients with perforated gastroduodenal ulcers: artificial neural network modelling indicates a highly complex disease.
Mortality prediction models for patients with perforated peptic ulcer (PPU) have not yielded consistent or highly accurate results. Given the complex nature of this disease, which has many non-linear associations with outcomes, we explored artificial neural networks (ANNs) to predict the complex interactions between the risk factors of PPU and death among patients with this condition. ⋯ The prediction of death was most accurate when using an ANN model with several univariate influences on the outcome. This finding demonstrates that PPU is a highly complex disease for which clinical prognoses are likely difficult. The incorporation of computerised learning systems might enhance clinical judgments to improve decision making and outcome prediction.

The evaluation and management of patients with vascular trauma or injury often involve rapid decision making in less than ideal circumstances. Immediate consequences such as hemorrhage, ischemia, compartment syndrome, thrombosis, and embolization may be life threatening and require immediate intervention. In addition, a number of regional and systemic complications of the initial vascular pathology are possible, such as shock, acute renal failure, myocardial infarction, or stroke. ⋯ These problems include traumatic injuries to the arterial or venous system, failure of vascular repairs or reconstructions, surgical site and graft infections, anastomotic complications, and compartment syndromes. In addition, arterial and venous complications secondary to the use of illicit intravenous drug use and cocaine-related vascular injury will be discussed. Finally, the increasingly important topic of iatrogenic or procedure-related vascular injuries and complications will be reviewed.

Special considerations in the interpretation of plain radiographs of the cervical spine in children. A review of the literature.
This review provides an overview of the special considerations with regard to correct diagnosis of plain radiographs of the pediatric cervical spine. Injuries to the cervical spine are rare in children. The leading trauma mechanism is motor vehicle injury. Plain radiographs are a common tool in the search for a diagnosis. Taking the growth process into account there are many differences to be found compared to the adult c-spine. Knowledge of these differences is important when working towards the correct interpretation of plain radiographs of the pediatric c-spine. ⋯ Knowledge of the c-spines characteristics is of major importance for every physician involved in pediatric trauma care. This could lead to not only avoiding misdiagnosis but could also lead to avoiding the overuse of computed tomography of the pediatric c-spine.

Is computed tomography necessary to determine liver injury in pediatric trauma patients with negative ultrasonography?
Abdominal trauma is the third most common cause of all trauma-related deaths in children. Liver injury is the second most common, but the most fatal injury associated with abdomen trauma. Because the liver enzymes have high sensitivity and specificity, the use of tomography has been discussed for accurate diagnosis of liver injury. ⋯ According to our findings, abdominal CT may not be necessary to detect liver injury if the patient has ALT and AST levels below 100 IU/L with a negative abdominal USG at admission and during follow-up.
