INTRODUCTION: Testicular torsion threatens testicular viability with increased risk of loss with delayed management. Still, healthy adolescents continue to be transferred from community hospitals to tertiary hospitals for surgical management for torsion even though adult urologists may be available. We sought to determine reasons behind patient transfer and to evaluate whether transfer to tertiary centers for testicular torsion leads to increased rates of testicular loss. MATERIALS AND METHODS: A retrospective chart review was performed for patients presenting to our free-standing pediatric tertiary care facility with surgically confirmed testicular torsion during the 5-year period between January 2011 and January 2016...

Placement of a ventricular catheter is the most common and easiest procedure in neurosurgery. Usually, the procedure is performed using anatomical landmarks. However, despite the apparent ease of this manipulation, its results are not always satisfactory. According to the literature data, the rate of improperly placed ventricular catheters amounts to 10-40%, which is directly correlated with the risk of shunt dysfunction. The use of special equipment, such as ultrasound scanners, endoscopes, stereotactic devices, and neuronavigation systems, significantly increases success of surgery...

BACKGROUND: With an increasing number of imaging studies being done nowadays, the number of incidentally discovered thyroid nodules is expected to rise. Although many of these nodules are small and benign in nature, some do grow and may cause pressure and/or thyrotoxic symptoms. Surgical resection has traditionally been recommended for symptomatic nodules but is associated with risk of hypothyroidism, bleeding, infection, and nerve damage. High intensity focused ultrasound (HIFU) is one of the non-surgical thermal ablation techniques that may serve as an alternative in the treatment of benign thyroid nodules...

The incidence of acute pancreatitis in children has increased over the last few decades. The development of pancreatic fluid collection is not uncommon after severe acute pancreatitis, although its natural course in children and adolescents is poorly understood. Asymptomatic fluid collections can be safely observed without any intervention. However, the presence of clinically significant symptoms warrants the drainage of these fluid collections. Endoscopic management of pancreatic fluid collection is safe and effective in adults...

Neurosonography is a promising technique for prenatal diagnosis, combining features of ultrasound imaging with fetal neurology. The brain is a three-dimensional structure, therefore observing brain structure in the three basic planes (sagittal, coronal and axial) is mandatory. The anterior fontanelle and sagittal suture may serve as acoustic ultrasound windows in the transvaginal brain scan, allowing to obtain high-resolution neuroimages of the intracranial structures. Furthermore, three-dimensional (3D) ultrasound combined with the transvaginal brain approach provides detailed and sophisticated neuroimages...

OBJECTIVES: Congenital hypothyroidism (CH) is most frequently encountered in newborns as an endocrine disorder characterized by thyroid hormone deficiency, and is one of the most common reasons for preventable mental retardation. This prospective study was designed to detect the pediatric occurrences of CH followed as euthyroid, with no anomalies detected via US on the gray scale, in comparison with a pediatric group with normal levels. METHODS: A total of 42 apparently healthy children with no thyroid disorder (Group 1) and 54 euthyroid CH (Group 2) using thyroid hormone were included in this study...

I read with interest the recently published article on ultrasound assisted pediatric lumbar puncture (UALP) by Gorn and colleagues(1) . As an advocate of point-of-care ultrasound in the pediatric emergency department setting, I am greatly encouraged by the study results. However, I would suggest clarification on several details of the study, some of which could potentially lead to biased outcomes. This article is protected by copyright. All rights reserved.

BACKGROUND AND OBJECTIVE: Return visits (RVs) to the emergency department (ED) consume medical resources and may represent a patient safety issue. The occurrence of unexpected RVs is considered a performance indicator for ED care quality. Because children are susceptible to medical errors and utilize considerable ED resources, knowing the factors that affect RVs in pediatric patients helps improve the quality of pediatric emergency care. METHODS: We collected data on visits made by patients aged ≤18years to EDs from the National Health Insurance Research Database...

BACKGROUND: Recognition of high blood pressure (BP) in children is poor, partly due to the need to compute age-sex-height referenced percentiles. This study examined the change in abnormal BP recognition before versus after the introduction of an electronic health record (EHR) app designed to calculate BP percentiles with a training lecture. METHODS AND RESULTS: Clinical data were extracted on all ambulatory, non-urgent encounters for children 3-18 years old seen in primary care, endocrinology, cardiology, or nephrology clinics at an urban, academic hospital in the year before and the year after app introduction...

Transjugular intrahepatic portosystemic shunt (TIPS) placement is a standard procedure for the treatment of portal hypertension complications. When this conventional approach is not feasible, alternative procedures for systemic diversion of portal blood have been proposed. A one-step interventional approach, combining minilaparotomy-assisted transmesenteric (MAT) antegrade portal recanalization and TIPS, is described in an adolescent with recurrent esophageal varice bleeding and portal cavernoma (PC). A 16-year-old girl was admitted to our Unit because of repeated bleeding episodes over a short period of time due to esophageal varices in the context of a PC...

BACKGROUND: In children, non-fractured wrists generally need no treatment and those that are fractured may only require a 3-week cast without any clinical follow-up. The ability to perform a point-of-care triage decision if radiographs are needed could improve patient flow and decrease unnecessary radiographs. The aim of this study was to evaluate the role of ultrasound (US) as a point-of-care triage tool for pediatric wrist injuries with limited training. METHODS: Physicians with no previous US experience attended a 1...

Highly complex medical documents, including ultrasound reports, are greatly mismatched with patient literacy levels. While improving radiology reports for readability is a longstanding concern, few articles objectively measure the effectiveness of physician training for readability improvement. We hypothesized that writing styles may be evaluated using an objective two-dimensional measure and writing training could improve the writing styles of radiologists. To test it, a simplified "grade vs. length" readability metric is developed based on results from factor analysis of ten readability metrics applied to more than 500,000 radiology reports...
