OBJECTIVES: Endoscopic ultrasound (EUS) is an established tool for evaluation of adults with acute recurrent pancreatitis (ARP) while data in pediatrics is limited. Our study assessed the role of EUS in identifying etiology including changes of chronic pancreatitis (CP) in children and adolescents with ARP. METHODS: Children with ARP (≥2 episodes of acute pancreatitis) were prospectively evaluated with a detailed clinical proforma and EUS. Subjects with known etiology of ARP or CP on ultrasonography/computed tomography and magnetic resonance cholangio-pancreatography (MRCP, Cambridge grade ≥3) were excluded...

AIM: Surgical management of pediatric extrahepatic portal vein obstruction requires meso-Rex bypass using autologous or synthetic grafts. Tissue-engineered vascular grafts (TEVGs) provide an alternative, but no validated animal models using portal TEVGs exist. Herein, we preclinically assess TEVGs as portal vein bypass grafts. MATERIALS & METHODS: TEVGs were implanted as portal vein interposition conduits in SCID-beige mice, monitored by ultrasound and micro-computed tomography, and histologically assessed postmortem at 12 months...

Introduction: Liver abscess is common in pediatric population in India. Children have unique set of predisposing factors and clinical features. Liver abscesses are infectious, space-occupying lesions in the liver; the two most common abscesses being pyogenic and amebic. Its severity depends on the source of the infection and the underlying condition of the patient. Materials and methods: A total of 34 patients less than 12 years were assessed in a retrospective study from January 2012 to 2016...

INTRODUCTION: In up to 20% of patients presenting with undescended testes, one or both are non-palpable. Whereas the most reliable means to exclude an abdominal testis is laparoscopy, there has been a lot of debate about the role of inguinal ultrasound (US) in detecting non-palpable inguinal testis. While we do not aim to add another paper claiming the benefits of US, we wanted to determine the excess capability of US to determine the correct surgical approach - inguinal or laparoscopy...

Importance: Prenatal and neonatal cystic kidney diseases are a group of rare disorders manifesting as single, multiple unilateral, or bilateral cysts or with increased echogenicity of the renal cortex without macroscopic cysts. They may be accompanied by grossly enlarged kidneys, renal oligohydramnios, pulmonary hypoplasia, extrarenal abnormalities, and neonatal kidney failure. The prognosis is extremely variable from trivial to very severe or even uniformly fatal, which poses significant challenges to prenatal counseling and management...

Ureteropelvic junction obstruction constitutes a major cause of progressive pediatric renal disease. The biological mechanisms underlying the renal response to obstruction can be investigated using a clinically relevant mouse model of partial unilateral ureteral obstruction (pUUO). Renal function and kidney morphology data can be evaluated using renal ultrasound, scintigraphy and uro-magnetic resonance imaging (uro-MRI), but these methods are poorly linked to histological change and not all are quantitative...

BACKGROUND: Rotavirus is the most common cause of severe diarrhea in Nepali children, accounting for 25-33% of childhood diarrhea hospitalizations. Two rotavirus vaccines recommended for inclusion in national immunization programs have been associated with a low risk of intussusception in post-marketing studies conducted in several countries. Data on the epidemiology of intussusception hospitalizations are lacking in Nepal. Thus, we aimed to describe the epidemiology of intussusception-associated hospitalizations among Nepali children in preparation for rotavirus vaccine introduction...

INTRODUCTION: The mesodiverticular band (MDB) is an embryologic remnant of the vitelline circulation, which carries the arterial supply to the Meckel diverticulum. In the event of an error of involution, a patent or nonpatent arterial band persists and extends from the mesentery to the apex of the antimesenteric diverticulum. This creates a snare-like opening through which bowel loops may herniate and become obstructed. This report describes 2 rare cases of small bowel occlusion owing to an internal hernia caused by a MDB...

INTRODUCTION: Ureteropelvic junction obstruction (UPJO) is one of the most frequent urological diseases affecting the pediatric population. It can be due to both intrinsic stenosis of the junction and extrinsic causes such as the presence of crossing vessels (CVs), which can be detected by color Doppler ultrasound (CD-US). Magnetic resonance urography (MRU) is a good alternative, but sedation and infusion of a contrast agent are required. OBJECTIVE: The aim of this study was to analyze the diagnostic accuracy of CD-US and MRU in visualizing CVs in pediatric hydronephrosis, in order to decide the correct diagnostic pathway in the pre-operative phase...

Tracheal intubation is a commonly done procedure in neonatal intensive care unit and delivery room during resuscitation. The confirmation of endotracheal tube (ETT) position should be done quickly as tube malposition is associated with various serious adverse outcomes like hypoxemia, right upper lobe collapse, atelectasis, air leak syndromes and esophageal intubation. ETT position can be confirmed by various methods like clinical sign, chest radiography, capnography, external digital tracheal palpation, ultrasonography (USG), respiratory function monitor, video-laryngoscope and fiberoptic devices...

OBJECTIVES: Cystic fibrosis related liver disease (CFLD) can develop silently in early life and approximately 10% of children with cystic fibrosis (CF) become cirrhotic before adulthood. Clinical, biological and ultrasound criteria used to define CFLD often reveal liver involvement at an advanced stage. The aim of this retrospective study was to assess the progression of liver stiffness measurement (LSM) in pediatric CF patients. METHODS: The change of LSM, expressed as kPa/year and %/year, was measured using transient elastography (TE, Fibroscan) in 82 CF children (median age: 6...

BACKGROUND: Point-of-care ultrasound (POCUS) is increasingly being used to differentiate cellulitis from abscess in the pediatric emergency department (ED). POCUS has also been shown to decrease length of stay (LOS) for other applications among adult patients. OBJECTIVE: We sought to determine if ED LOS differed for children presenting with skin and soft tissue infections who received POCUS versus radiology-performed ultrasound. METHODS: We performed a retrospective cohort study of children presenting to an urban pediatric ED between January 2011 and June 2013 with a diagnosis of cellulitis or abscess who underwent soft tissue ultrasound...
