Influence of different post-contrast time points on dynamic contrast-enhanced (DCE) MRI T staging in breast cancer.

Purpose: to assess whether MRI T stage of breast cancer lesions (BCLs) is affected by maximum diameter (MD) measured at different post-contrast time points (TPs) on different acquisition planes on dynamic contrast-enhanced (DCE) MRI sequence.

Methods: 53 DCE-MRI examinations of patients with BCLs were retrospectively selected. MD of BCLs was measured on axial, coronal and sagittal planes on DCE images at five different post-contrast TPs.

Unique association of cardiac amyloidosis and right atrial tumor thrombus in a patient with hepatocellular carcinoma.

Tumor thrombus is a very rare complication observed in patients with hepatocellular carcinoma. We report a unique case of hepatocellular carcinoma with extension of tumor along the inferior vein cava into the right atrium, in a patient with cardiac amyloidosis and without any cardio respiratory distress or typical clinical findings suggestive of cardiovascular involvement from cardiac amyloidosis. Cardiac magnetic resonance imaging is a useful tool to assess intracardiac tumor extension as well as to provide myocardial tissue characterization.

Clinical significance and sonographic evolution of enlarged abdominal lymph nodes in children.

Aim: Paediatric evidence about the clinical implications of enlarged abdominal lymph nodes (EALN) is not univocal. The main purpose of our study was to evaluate the clinical significance and the morphological evolution of enlarged abdominal nodes in children with recurrent abdominal pain.

Methods: All children with recurrent abdominal pain diagnosed with EALN were enrolled at the involved centres between September 2017 and June 2018.

Efficacy of a mixture of probiotic agents as complementary therapy for chronic functional constipation in childhood.

Background: About 30% of constipated children continue to struggle with constipation beyond puberty. Growing interest has recently raised on the use of probiotics as complementary therapy for FC, in order to prevent the possible PEG-related intestinal dysbiosis. Our study aimed at evaluating the effect on childhood FC of a probiotic mixture (PM), including Bifidobacteria breve M-16 V®, infantis M-63®, and longum BB536®.

Gastroesophageal reflux in young children and adolescents: Is there a relation between symptom severity and esophageal histological grade?

Background: The pediatric literature about the correlation between symptoms and histological lesions in patients investigated for gastroesophageal reflux disease is scarce and inconclusive. The primary aim of the present study was to assess the relation between the complained symptom severity and the esophageal histological grade, through the use of validated and reliable scores.

Methods: All children ages between 2 and 17 years referred to perform upper gastrointestinal endoscopy because of gastroesophageal reflux disease symptoms were asked to complete the Pediatric Gastroesophageal Symptom and Quality of Life validated questionnaire, investigating the main symptoms complained and their impact on daily life and school activities.

Impact of hiatal hernia on pediatric dyspeptic symptoms.

Objectives: Hiatal hernia (HH) affects from 10% to 50% of adult population. The correlation between HH, gastroesophageal reflux disease, dyspeptic symptoms, and esophagitis has long been known in adults. The primary objective of our prospective observational study was to estimate the prevalence of HH in children undergoing esophagogastroduodenoscopy (EGD), irrespective of their symptoms.
