[Exposure to CT scans in childhood and long-term cancer risk: A review of epidemiological studies].

Amongst medical exams requiring ionizing radiation, computed tomography (CT) scans are used more frequently, including in children. These CT examinations are associated with absorbed doses that are much higher than those associated with conventional radiology. In comparison to adults, children have a greater sensitivity to radiation and a longer life span with more years at cancer risks.

Paediatric and adolescent Hodgkin lymphoma: information derived from diffuse organ uptake of 18 F-fluorodeoxyglucose on pre-treatment and on interim PET/CT.

Purpose: To evaluate, in children with Hodgkin lymphoma (HL), the frequency and intensity of visually diffuse FDG uptake by selected organs at baseline (bPET) and on interim PET/CT (iPET), and to evaluate the relation between FDG uptake, metabolic response and evolution of the disease with treatment.

Patients And Methods: Thirty children with HL had bPET and then iPET after two cycles of treatment, which were blind-read retrospectively. Excluding sites with focal uptake, diffuse FDG uptake by thymus, bone marrow at iliac crests, liver, spleen, and the spinal cord at the 12th thoracic vertebra (Th12) was evaluated visually using a three-point scoring method and semiquantitatively by measuring SUVmax.

Clinical predictors of radiographic abnormalities among infants with bronchiolitis in a paediatric emergency department.

Background: Acute viral respiratory exacerbation is one of the most common conditions encountered in a paediatric emergency department (PED) during winter months. We aimed at defining clinical predictors of chest radiography prescription and radiographic abnormalities, among infants with bronchiolitis in a paediatric emergency department.

Methods: We conducted a prospective cohort study of children less than 2 years of age with clinical bronchiolitis, who presented for evaluation at the paediatric emergency department of an urban general hospital in France.

Impact of chest radiography for children with lower respiratory tract infection: a propensity score approach.

Background: Management of acute respiratory tract infection varies substantially despite this being a condition frequently encountered in pediatric emergency departments. Previous studies have suggested that the use of antibiotics was higher when chest radiography was performed. However none of these analyses had considered the inherent indication bias of observational studies.

Infant Odontogenic Myxoma: a specific entity.

Introduction: In children, and specifically in infants, odontogenic myxomas are extremely rare. In infants, myxoma seems to display mostly the same clinical, radiological and pathological characteristics. This paper presents a series of odontogenic myxomas in infant patients.

Specificity of paediatric jawbone lesions: tumours and pseudotumours.

Introduction: Characteristics and epidemiology of jaw tumours have been described mostly in adults. Compared with their adult counterparts, childhood jaw tumours show considerable differences. The aim of this study was to describe the different jaw tumours in children, define diagnostic tools to determine their specificity and describe optimal treatment.

Retrospective French nationwide survey of childhood aggressive vascular anomalies of bone, 1988-2009.

Objective: To document the epidemiological, clinical, histological and radiological characteristics of aggressive vascular abnormalities of bone in children.

Study Design: Correspondents of the French Society of Childhood Malignancies were asked to notify all cases of aggressive vascular abnormalities of bone diagnosed between January 1988 and September 2009.

Results: 21 cases were identified; 62% of the patients were boys.

Originality of new imaging techniques in pediatric radiology.

Pediatric radiology is a specialty that combines the performances of imaging and radio-protection. It also has to deal with absence of cooperation and motion of the child which have limited for a long time many radiological applications. Technical advances with shorter acquisition time in CT and MRI, higher frequencies in ultrasound, and digitalization in conventional radiology have widened the indications especially with the new modalities.

Proximal tibial epiphyseal intraosseous schwannoma: a rare entity.

Schwannoma is a benign nerve sheath tumor most commonly located in the soft tissue. Occasionally, schwannomas involve osseous structures. The rarity of osseous involvement leads to omission of schwannoma from the initial differential diagnosis in the majority of cases.

Fetal and neonatal ovarian cysts: is surgery indicated?

Objectives: To evaluate the frequency of ovarian torsion in neonates with ovarian cysts (OCs) and to analyze the outcome after surgical treatment.

Methods: A retrospective review of all infants with OCs managed in our institution during 20 years, was conducted. Our management included a follow-up (FU) of prenatal serial ultrasound (US) scan without prenatal cyst aspiration and early postnatal US scan.
