Data linking cumulative lifetime vitamin D status with skeletal outcomes are lacking. We show that increasing cumulative sun exposure was associated with higher bone mineral density in younger males and protective against fractures in females independent of current vitamin D. This supports the concept that cumulative sun exposure is an important contributor to skeletal health. INTRODUCTION: While low 25-hydroxyvitamin D levels are associated with increased fracture risk, this reflects only recent sun exposure...

INTRODUCTION: Despite radiography being the gold standard in evaluation of orthopedic injuries, using bedside ultrasonography has several potential supremacies such as avoiding exposure to ionizing radiation, availability in pre-hospital settings, being extensively accessible, and ability to be used on the bedside. The aim of the present study is to evaluate the diagnostic accuracy of ultrasonography in detection of extremity bone fractures. METHODS: This study is a case series study, which was prospectively conducted on multiple blunt trauma patients, who were 18 years old or older, had stable hemodynamic, Glasgow coma scale 15, and signs or symptoms of a possible extremity bone fracture...

In pediatrics ultrasound has long been viewed more favorably than imaging that exposes patients to radiation and iodinated contrast or requires sedation. It is child-friendly and diagnostic capabilities have been improved with the advent of contrast-enhanced ultrasound (CEUS). The application of CEUS is indeed promising. However, no ultrasound contrast agent manufactured today is registered for pediatric use in Europe. The contrast agent SonoVue(®) has recently been approved by the FDA under the name of Lumason(®) to be used in hepatic investigations in adults and children...

Background The incidence of fragility fractures of the pelvis is increasing. Established methods to diagnose this condition include X-rays, computed tomography (CT) and magnetic resonance imaging (MRI). Dual energy CT (DECT) is a modern technology for the imaging of bone oedema/bruises and has been used in injuries of the extremities and spine. It is unclear whether this technique can also be used in fragility fractures of the pelvis. The aim of this study was to perform a literature research and survey of the "AG Becken III" members of the German Society of Trauma Surgery (DGU) on the usefulness of DECT in fractures of the pelvis...

Meningiomas represent the most common tumours of the central nervous system in adults. Risk factors include ionizing radiation, female hormones exposure, head trauma, cell phone use, breast cancer and family history of meningioma. Despite complete surgical resection, natural history of meningiomas often includes local recurrence but very few metastatic meningiomas have been reported. Here, we report the case of a metastatic meningioma. A 43-year-old woman was firstly treated for a symptomatic parietal meningioma WHO grade II by surgical resection followed by an irradiation of the surgical bed...

BACKGROUND: Computer-assisted corrective osteotomy using a mirror image of the normal contralateral shape as reference is increasingly used. Instead, we propose to use the shape predicted by statistical learning to deal with cases demonstrating bilateral abnormality, such as bilateral trauma, congenital disease, and metabolic disease. METHODS: Computed tomography (CT) scans of 100 normal forearms were used in this study. The whole bone shape was predicted from its partial shape based on statistical learning of the other 99 bones...

Epidural anesthesia is a versatile technique widely used in treating lumbar spinal pain syndromes. Complications during these procedures can arise either from needle placement or from administration of medication. Potential risks include infection, hematoma, intravascular or subdural injections of medication, direct nerve trauma, air embolism, entry into a disc space, urinary retention, radiation exposure, and hypersensitivity reactions. The objective of this article is to review the complications of lumbar epidural injections and discuss the potential pitfalls related to these procedures...

BACKGROUND: Computed tomography is commonly used to rule out intra-abdominal injury (IAI) in children, despite associated cost and radiation exposure. Our purpose was to derive a prediction rule to identify children at very low risk for IAI after blunt abdominal trauma (BAT) for whom a CT scan of the abdomen would be unnecessary. STUDY DESIGN: We prospectively enrolled children younger than 16 years of age who presented after BAT at 14 Level I pediatric trauma centers during 1 year...

PURPOSE: Conventional radiography is frequently performed in pediatric patients in whom fractures and dislocations are suspected. However, until now, the rate of positive findings of the most commonly performed radiographic examinations in pediatric patients is unknown. The aim of this study was to evaluate the number of positive findings in the 20 most frequently requested standard radiographic examinations in pediatric patients in a level 1 trauma center systematically. METHODS: A transversal cohort study was conducted at a level 1 trauma center in Germany (2008-2014)...

Detonation of a 10-kiloton nuclear bomb in an urban setting would result in >1 million casualties, the majority of which would present with combined injuries. Combined injuries, such as peripheral tissue trauma and radiation exposure, trigger inflammatory events that lead to multiple organ dysfunction (MOD) and death, with gastrointestinal (GI) and pulmonary involvement playing crucial roles. The objective of this study was to develop an animal model of combined injuries, peripheral tissue trauma (TBX animal model) combined with total body irradiation with 5% bone marrow shielding (TBI/BM5) to investigate if peripheral tissue trauma contributes to reduced survival...

In endovascular catheter interventions, the determination of the three-dimensional (3D) catheter shape can increase navigation information and help reduce trauma. This study describes a shape determination method for a flexible interventional catheter using ultrasound scanning and a two-step particle filter without X-ray fluoroscopy. First, we propose a multi-feature, multi-template particle filter algorithm for accurate catheter tracking from ultrasound images. Second, we model the mechanical behavior of the catheter and apply a particle filter shape optimization algorithm to refine the results from the first step...

BACKGROUND: On March 11, 2011, a magnitude 9.0 earthquake occurred off of Japan's Pacific coast, which was followed by huge tsunamis that destroyed many coastal cities in the area. Due to the earthquake and subsequent tsunami, malfunctions occurred at the Fukushima Daiichi (Fukushima I) nuclear power plant, resulting in the release of radioactive material in the region. While recent studies have investigated the effects of these events on the mental health of adults in the region, no studies have yet been performed investigating similar effects among children...

OBJECTIVES: Pediatric cervical spine injuries (CSIs) are rare but potentially fatal injuries. Plain radiographs (x-rays) and computed tomography (CT) are used to diagnose CSIs. Given concerns related to radiation exposure, the utility of x-rays in diagnosing CSIs compared with other forms of imaging must be examined. METHODS: Patients younger than 19 years presenting with possible CSI to an urban tertiary care hospital who received imaging for possible CSI between January 1, 2011, and December 31, 2013, were included...

BACKGROUND: Diagnosing NAT (non-accidental trauma) includes a skeletal survey to identify injuries. A follow-up survey is performed for missed injuries. This study examines the necessity of follow-up surveys. METHODS: The trauma database identified cases of suspected NAT in <4 years olds (2013-2014). Data were stratified by survey, age, injury, then analyzed for the prevalence of findings. All analyses (relative risk, prevalence and odds ratios) utilized RealStats Resource Pack (Trento, Italy)...

BACKGROUND: Thoracic injuries are a major cause of death associated with blunt trauma in children. Screening for injury with chest x-ray study, compared with chest computed tomography (CT) scan, has been controversial, weighing the benefits of specificity with the detriment of radiation exposure. OBJECTIVE: To identify predictors of thoracic injury in children presenting as trauma activations to a Level I trauma center after blunt torso trauma, and to compare these predictors with those previously reported in the literature...

OBJECTIVE: Because of concern over medical ionizing radiation exposure of children, contrast-enhanced ultrasound (CEUS) has generated interest as an inexpensive, ionizing radiation-free alternative to CT and MRI. CEUS has received approval for pediatric hepatic use but remains off-label for a range of other applications. The purposes of this study were to retrospectively analyze adverse incidents encountered in pediatric CEUS and to assess the financial benefits of reducing the number of CT and MRI examinations performed...

BACKGROUND: Computed tomography (CT) of the cervical spine (C-spine) is routinely ordered for low-impact, non-penetrating or "simple" assault at our institution and others. Common clinical decision tools for C-spine imaging in the setting of trauma include the National Emergency X-Radiography Utilization Study (NEXUS) and the Canadian Cervical Spine Rule for Radiography (CCR). While NEXUS and CCR have served to decrease the amount of unnecessary imaging of the C-spine, overutilization of CT is still of concern...

OBJECTIVE: The protocol for the management of mild cranioencephalic trauma in the emergency department was changed in July 2013. The principal innovation was the replacement of systematic X-ray in infants with clinical observation. The aims of this study were to determine whether there was, 1) a reduction in the ability to detect traumatic brain injury (TBI) in the initial visit to Emergency, and 2) a change in the number of requests for imaging tests and hospital admissions. METHODOLOGY: This was a retrospective, descriptive, observational study...
