Traumatic brain injury (TBI) is the leading cause of considerable mortality and morbidity in children, who are the main users of unpowered scooters. The aim of this study was to explore the characteristics of unpowered scooter injuries in children and to identify predictors of the occurrence of TBI.

Factors contributing to uncertainty in paediatric abdominal ultrasound reports in the paediatric emergency department.

Background: Abdominal pain, which is a common cause of children presenting to the paediatric emergency department (PED), is often evaluated by ultrasonography (US). However, uncertainty in US reports may necessitate additional imaging.

Objective: In this study, we evaluated factors contributing to uncertainty in paediatric abdominal US reports in the PED.

Brain natriuretic peptide as a clinical screening tool for the diagnosis of Kawasaki disease.

N-terminal pro-brain natriuretic peptide (NT-proBNP) has been studied as a diagnostic screening tool for Kawasaki disease (KD). However, brain natriuretic peptide (BNP) has been less studied while has less variability among age groups. We aimed to find out if BNP can be used as a diagnostic screening tool for KD in Korea.

Delta Neutrophil Index Does Not Differentiate Bacterial Infection without Bacteremia from Viral Infection in Pediatric Febrile Patients.

Introduction: We sought to determine whether the delta neutrophil index (DNI), a marker that is reported to be used to predict the diagnosis, prognosis, and disease severity of bacteremia and sepsis, is useful in differentiating bacterial infection without bacteremia (BIWB) from viral infections (VI) in pediatric febrile patients in the emergency department (ED). Method: We conducted a retrospective analysis of febrile patients’ medical records from the pediatric ED of the teaching hospital. The patients with BIWB and those with VI were identified with a review of medical records.

Effect of a Virtual Reality Environment Using a Domed Ceiling Screen on Procedural Pain During Intravenous Placement in Young Children: A Randomized Clinical Trial.

Importance: Distraction using virtual reality (VR) has been found to provide a clinically significant reduction in the experience of pain during various painful procedures. Commercially available VR systems usually require the user to wear a head-mounted display helmet, which can be challenging for young children, and whether VR can reduce pain during intravenous (IV) placement in young children is currently unknown.

Objective: To determine whether a VR environment using a novel domed ceiling screen reduces distress among children over the course of IV placement compared with standard care in a pediatric emergency department.

Tablet personal computer distraction during intravenous placement for young children in the pediatric emergency department: A pilot study.

Background: Intravenous (IV) placement is a common procedure experienced by children visiting the pediatric emergency department (PED). However, uncontrolled anxiety and pain cause children to interfere with the procedure. In this pilot study, we sought to evaluate the effectiveness of tablet personal computers as a distraction method during IV placement.

Virtual reality environment using a dome screen for procedural pain in young children during intravenous placement: A pilot randomized controlled trial.

We assessed the feasibility and potential efficacy of a virtual reality (VR) environment using a dome screen as a distraction method in young children during intravenous (IV) placement in the pediatric emergency department. This randomized controlled pilot study enrolled children aged 2 to 6 years who underwent IV placement into either the intervention group or the control group. Children in the intervention group experienced VR using a dome screen during IV placement.

Role of the urinary N-acetyl-beta-D-glucosaminidase/creatinine (NAG/Cr) ratio in discriminating between true and false pyuria in sterile urine bag specimens.

Introduction: Urethral catheterization (CATH) and suprapubic aspiration (SA) are reliable methods of collecting urine for the diagnosis of urinary tract infections (UTIs), but both are invasive and difficult. Therefore, urine collection through a sterile urine bag (SUB) is commonly used for UTI screening. However, when pyuria is found in SUB specimens, it is difficult to interpret whether this result is true or false.

Are parents' statements reliable for diagnosis of serious bacterial infection among children with fever without an apparent source?: A retrospective study.

Serious bacterial infection (SBI) is a major cause of morbidity and mortality in children. Distinguishing SBI from self-limiting viral infections is a very important task in the emergency department (ED), especially in the children with fever without source (FWS). The aim of this study was to analyze whether parents' statements about clinical manifestations, which were categorized according to grades, are related to the actual diagnosis of SBI in children with FWS.

Role of follow-up endoscopic examination in treatment response assessment for patients with gastric diffuse large B cell lymphoma.

Objective: According to lymphoma guidelines, gastric diffuse large B cell lymphoma (DLBCL) patients should undergo regular computed tomography (CT) and/or positron emission tomography (PET) examinations to assess treatment response. Endoscopic examinations are not indicated in the guidelines. The aim of this study was to investigate the utility of endoscopic examinations during and after treatment for DLBCL.

Multiple cancers in a patient with systemic sclerosis and aggravated interstitial lung disease by chemotherapy.

Although the relationship between malignancy risk with systemic sclerosis (SSc) has been inconclusive, there are some previous studies for a positive correlation. Most patients with SSc have some degree of lung parenchymal involvement in the form of interstitial thickening and fibrosis. Interstitial lung disease is the most common pulmonary manifestation of SSc.

Effects of degumming conditions on electro-spinning rate of regenerated silk.

Electro-spun silk webs are potentially good candidates as tissue engineering scaffolds owing to their good bio- and cyto-compatibility. However, the low fabrication rate of electro-spun silk mats has been one of the obstacles in the mass production of such nanofibrous silk mats in applications to the biomedical field. In this study, the effects of degumming ratio and silk concentration on the electro-spinning process were investigated by using regenerated silk with different residual sericin contents and different silk concentrations in terms of the morphology and structure of the electro-spun silk web.

[A case of severe bevacizumab-induced ischemic pancolitis, treated with conservative management].

Bevacizumab (Avastin(Ⓡ)) is a monoclonal antibody against the vascular endothelial growth factor (VEGF) receptor that increases the overall survival rate when added to standard chemotherapy regimens in patients with metastatic colorectal cancer. The known toxicities of bevacizumab are hypertension, proteinuria, wound healing complications, arterial thrombosis, bleeding, and gastrointestinal complications. Especially ischemic colitis can rapidly develop into bowel perforation, so an emergency operation often is needed.

[A case of pseudomembranous colitis in a juvenile rheumatoid arthritis patient taking methotrexate].

Pseudomembranous colitis is mainly caused by antibiotics and Clostridium difficile infection. But conditions such as gastrointestinal surgery, antacid medication, anti-neoplastic agent or immunosuppressive agent which influences the normal flora of colon can induce colitis without the administration of any antibiotics. We experienced a 13 year-old male who was taking low-dose methotrexate for juvenile rheumatoid arthritis complained diarrhea and abdominal pain for 3 weeks.
