INTRODUCTION: Several techniques for the transversus abdominis plane (TAP) block have been described. The extent of sensory changes using an ultrasound-guided posterior TAP block (pTAP) remains unclear in pediatric patients. The primary aim of this study was to report the extent of sensory changes achieved with pTAP; specifically the highest thoracic dermatome anesthetized. Secondary outcomes were pain scores (PS), opioid consumption, and complications. METHODS: We retrospectively reviewed the medical records of patients less than 21 years of age undergoing abdominal surgery with a unilateral or bilateral pTAP(s) for postoperative analgesia...

OBJECTIVES: The estimation of skeletal maturity is a useful tool in pediatric practice to determine the degree of delay or advancement in growth disorders and the effectiveness of treatment in conditions that influence linear growth. Skeletal maturity of children is commonly assessed using either Greulich-Pyle (GP) or Tanner-Whitehouse methods (TW2 and TW3). However, a less invasive ultrasonic method, that does not use ionizing radiation, has been suggested for use in epidemiological studies of skeletal maturity...

BACKGROUND: Though uncommon in children, pediatric thyroid nodules carry a higher risk of malignancy than adult nodules. While fine-needle aspiration (FNA) has been well established as the initial diagnostic test in adults, it has been more slowly adopted in children. The purpose of this study was to examine the comparative cost of FNA versus initial diagnostic lobectomy (DL) in the pediatric patient with an ultrasound-confirmed thyroid nodule. METHODS: A decision tree model was created using an adolescent with an asymptomatic thyroid nodule as the reference case...

Brain pathology is an important cause of morbidity and mortality in neonates, especially in the premature population. While conventional two-dimensional neurosonography is traditionally used for screening, diagnosis and monitoring of brain disorders such as germinal matrix hemorrhage, periventricular leukomalacia and hydrocephalus, three-dimensional ultrasonography has gained popularity in a variety of clinical applications in recent years. Three-dimensional ultrasonography is not yet widely utilized in pediatric imaging but is a potentially powerful tool for evaluating the neonatal brain...

Background - Vesicoureteral reflux (VUR) is a common pediatric urologic disorder. After the first urinary tract infection (UTI), imaging studies are recommended, starting with a renal ultrasound (US) and voiding cystourethrography (VCUG). We propose to determine whether abnormalities found on US can help indicate the necessity of VCUG in children after the first urinary tract infection. Methods - A retrospective study included all children admitted with their first episode of urinary tract infection from January 2007 to December 2012...

OBJECTIVES: The diagnosis of pediatric community-acquired pneumonia (CAP) is based on clinical criteria. Even though chest x-ray (CXR) is only recommended in severe cases, it is often requested from physicians in mild cases, thus increasing radiation exposure. Lung ultrasound (LUS) is not included in the diagnostic workup. The objective of this study was to evaluate the diagnostic performance of LUS against CXR. METHODS: Children who presented to the emergency department with clinical signs suggesting CAP and had already been evaluated with a CXR were included in the study...

Congenital heart disease is the most common congenital malformation and approximately 3 in 1000 newborns have critical congenital heart disease (CCHD). Timely diagnosis affects morbidity, mortality, and disability, and newborn pulse oximetry screening has been studied to enhance detection of CCHD. In this position statement we present an evaluation of the literature for pulse oximetry screening. Current detection strategies including prenatal ultrasound examination and newborn physical examination are limited by low diagnostic sensitivity...

X-rays and ventriculograms were the first imaging modalities used to localize intracranial lesions including brain tumors as far back as the 1880s. Subsequent advances in preoperative radiological localization included computed tomography (CT; 1971) and MRI (1977). Since then, other imaging modalities have been developed for clinical application although none as pivotal as CT and MRI. Intraoperative technological advances include the microscope, which has allowed precise surgery under magnification and improved lighting, and the endoscope, which has improved the treatment of hydrocephalus and allowed biopsy and complete resection of intraventricular, pituitary and pineal region tumors through a minimally invasive approach...

Bowel dysfunction affected by functional factors, mechanical factors or surgical damage may lead to constipation, fecal incontinence and other overlapped symptoms, which is only the tip of the iceberg. Anorectal manometry can provide combined dysfunction information of four subtypes, including sphincter dysfunction, dyssynergic defecation, sensory disability and insufficient rectal expel force, which are underlying pathophysiology of defecation dysfunction. Anorectal manometry can be helpful in optimizing protocol or predicting success in pelvic floor dyssynergic syndrome of defecation, fecal incontinence or anorectal pain, stoma closure and pediatric intractable constipation...
