Impact of trauma center status on radiology resident performance in detecting non-accidental trauma on the WIDI SIM exam.

Purpose: To evaluate whether adult and pediatric trauma center status, as well as the presence of dedicated child protection teams, influences radiology resident performance in detecting non-accidental trauma on the Emergent/Critical Care Imaging Simulation (WIDI SIM) exam.

Materials And Methods: We retrospectively analyzed 639 WIDI SIM exam scores for four pediatric non-accidental trauma cases completed by radiology residents across 33 programs. Residents were stratified by level (R1-R4) and institutional factors, including adult trauma center status, pediatric trauma center status, and child protection team presence.

Multi-Energy Evaluation of Image Quality in Spectral CT Pulmonary Angiography Using Different Strength Deep Learning Spectral Reconstructions.

Rationale And Objectives: To evaluate and compare image quality of different energy levels of virtual monochromatic images (VMIs) using standard versus strong deep learning spectral reconstruction (DLSR) on dual-energy CT pulmonary angiogram (DECT-PA).

Materials And Methods: A retrospective study was performed on 70 patients who underwent DECT-PA (15 PE present; 55 PE absent) scans. VMIs were reconstructed at different energy levels ranging from 35 to 200 keV using standard and strong levels with deep learning spectral reconstruction.

Deployment and testing of an automated medical equipment service communication and documentation system at a rural hospital in Kenya.

Background: The Medical Equipment Network Documentation System (MENDS) provides a simple communication network for equipment servicing from failure to restoration. It is a text messaging-based platform, designed to use existing technologies in place in low- and middle-income settings. The system gathers and relays information about equipment service requests and reports and automatically saves them to an online database.

Ionizing Radiation Exposure in Pediatric Patients With Intestinal Failure.

Background: Children with intestinal failure (IF) are frequently exposed to imaging studies using ionizing radiation. Due to many advancements in care of pediatric patients with IF, the number of patients living with this condition is growing. This burden of disease as pertains to pediatric IF patients has not been previously described.

A Retrospective Evaluation of Airway Anatomy in Young Children and Implications for One-Lung Ventilation.

Objective: One-lung ventilation (OLV) in children remains a niche practice with few studies to guide best practices. The objective of this study was to describe lower airway anatomy relevant to establishment of OLV in young children.

Design: Retrospective, observational study using pre-existing studies in the electronic health record.

Necrotizing Enterocolitis and Growth in Preterm Infants Fed Predominantly Maternal Milk, Pasteurized Donor Milk, or Preterm Formula: A Retrospective Study.

 To evaluate the association between necrotizing enterocolitis (NEC), growth, and feeding.  This is a retrospective study of 551 infants (birth weight ≤ 1,500 g, ≤32 weeks' gestation). NEC, Bell's stage ≥ 2, was confirmed by independent review of sentinel radiographs.

Imaging of primary pediatric lymphoma of bone.

Background: Primary pediatric bone lymphoma is a rare form of non-Hodgkin lymphoma. Unlike nodal forms of lymphoma, imaging abnormalities in lymphoma of bone do not resolve rapidly in conjunction with treatment and radiologic findings can remain abnormal for years, making it difficult to evaluate treatment response.

Objective: To evaluate the utility of imaging in assessment of patients with primary pediatric bone lymphoma.

Imaging of the elbow in children with wrist fracture: an unnecessary source of radiation and use of resources?

Background: Anecdotally accepted practice for evaluation of children with clinically suspected or radiographically proven wrist fracture in many urgent care and primary care settings is concurrent imaging of the forearm and elbow, despite the lack of evidence to support additional images. These additional radiographs may be an unnecessary source of radiation and use of health care resources.

Objective: Our study assesses the necessity of additional radiographs of the forearm and elbow in children with wrist injury.

Bilateral parotitis as the initial presentation of childhood sarcoidosis.

The differential diagnosis of bilateral parotid gland enlargement in children includes infectious, inflammatory, and neoplastic disorders. We present the case of a 13-year-old male who presented with a 5-week history of bilateral parotid swelling. On exam, both parotid glands were nontender, smooth, and diffusely enlarged.

Adnexal masses in female pediatric patients.

Objective: This article reviews the range of adnexal masses that present in pediatric females. The preferred imaging modalities, the appearance of the normal ovaries, and the epidemiology of ovarian diseases and abnormalities are discussed. The illustrated abnormalities include simple and complex ovarian and paraovarian cysts, neoplasms, ovarian torsion, ectopic pregnancy, and tuboovarian abscess, with attention to the imaging features and vascular flow patterns that help distinguish surgical from nonsurgical cases, malignant from benign lesions, and ovarian abnormalities from mimickers.

Occult megarectum--a commonly unrecognized cause of enuresis.

Objective: To determine whether occult megarectum remains a commonly unrecognized cause of enuresis and whether treating it will cure enuresis in most children. A landmark study proved constipation was a commonly unrecognized cause of enuresis in 1986 in which constipation was defined as abnormal rectal distension. However, modern recommendations have focused on signs of functional constipation, such as hard or rare stools.

Neonatal systemic thromboembolism secondary to ductus arteriosus aneurysm and patent foramen ovale.

Ductus arteriosus aneurysm (DAA) can be associated with neonatal thromboembolism. We report a neonate with systemic thromboembolism causing acute cerebral infarction with DAA, arterial, and venous thrombosis, discovered on CT angiography. The role of DAA was suspected as a potential etiology of systemic thromboembolism in this case.

Pediatric occupants, restraint use, and injuries in motor vehicle crashes - biomed 2011.

Pediatric occupants are vulnerable in motor vehicle crashes (MVCs), and alternative restraints have been developed for their protection. This study sought to characterize injuries in MVCs for pediatric occupants and to identify scenarios that may benefit from enhanced vehicle safety. Using the NASS-CDS database (2000-2008), pediatric occupants (< 19 yr old) were characterized by their age and injuries to look at national averages in MVCs.

Infantile orbital cellulitis secondary to community-associated methicillin-resistant Staphylococcus aureus.

Community-associated methicillin-resistant Staphylococcus aureus (MRSA) is increasingly recognized as a cause of invasive disease in children. Orbital cellulitis typically occurs in older children, but it can occasionally affect infants and neonates. We report 2 infants with sepsis and orbital cellulitis caused by community-associated MRSA and review the relevant literature.

Pyomyositis due to Streptococcus pneumoniae.

Pyomyositis is an unusual but potentially serious disease in children. Staphylococcus aureus is the most commonly implicated pathogen, but pneumococcal pyomyositis is very rare. Clinical diagnosis of pyomyositis can be difficult often mimicking septic arthritis of the hip or appendicitis.

Pregnant female anthropometry from ct scans for finite element model development.

In this study, anthropometry data is collected from a CT scan of a pregnant abdomen at 32 weeks gestation. Over 1500 fetal losses occur each year in the United States due to motor vehicles crashes. Pregnant occupants involved in motor vehicle crashes are at risk for pregnancy-specific injuries.

Spontaneous regression of langerhans cell histiocytosis in a neonate with multiple bony lesions.

We report the case of a newborn with Langerhans cell histiocytosis involving the skin and multiple bones. All lesions resolved without therapy. This case underscores the benefits of a conservative approach in the absence of risk organ involvement.

Common Pediatric Sports Injuries.

This article reviews the common acute and overuse injuries encountered in the pediatric athlete. Acute injuries are usually physeal or avulsion fractures relating to a single traumatic event. Overuse injuries are the result of repetitive stress and include the common traction apophysitis, osteochondritis dissecans, and stress fractures.
