Association of N-acetylcysteine and glucagon during percutaneous cholangiography in the treatment of inspissated bile syndrome.

Inspissated bile syndrome (IBS) is a rare neonatal disease. In the majority of cases, it resolves spontaneously and treatment is conservative. Follow-up is recommended with close monitoring of laboratory tests.

Renal safety in pediatric imaging: randomized, double-blind phase IV clinical trial of iobitridol 300 versus iodixanol 270 in multidetector CT.

Background: It is debated whether iso-osmolar and low-osmolar contrast media are associated with different incidences of contrast medium-induced nephropathy (CIN) in patients with renal insufficiency.

Objective: To compare the incidence of CIN in children undergoing contrast-enhanced multidetector computer tomography (MDCT) with intravenous injection of low-osmolar (iobitridol, Xenetix® 300) or an iso-osmolar (iodixanol, Visipaque® 270) iodinated contrast medium.

Materials And Methods: One hundred forty-six children with normal renal function were included in this multicenter trial and underwent contrast-enhanced MDCT.

Uterus didelphys, hemihydrocolpos and empty ipsilateral lumbar fossa in a newborn girl: involuted dysplastic kidney rather than renal agenesis.

We report a case of Herlyn-Werner-Wunderlich syndrome diagnosed in the neonatal period. US revealed the classic association of a uterus didelphys with blind hemivagina and no ipsilateral kidney. The diagnosis was established by postnatal US and confirmed by MRI.

[Sonography with color and pulsed Doppler in fetal pulmonary malformations].

Objective: Evaluate the advantages of color Doppler and pulsed Doppler in the diagnosis and prognosis of fetal pulmonary malformations.

Materials And Method: This retrospective study of 24 fetuses explored pulmonary malformations using sonography. A classification into four groups was made based on the presence of cysts and the echogenicity of the lesion, then analysis of video recordings including Doppler with an interpretation chart: afferent vessel, color chart, spectrum shape (afferent vessel and within the malformation) to determine the contribution of Doppler within each group.

[Management of abdominal trauma in children].

Management of abdominal trauma in children has considerably changed over the last fifteen years. This is mainly due to advances in imaging techniques combined with a more conservative approach. Non-surgical management is frequently preferred with close clinical and biological surveillance, in addition to comprehensive imaging evaluation.

Anterior axial ultrasound in monitoring infants with Pavlik harness.

Real-time ultrasonography has been used for diagnosis and screening of developmental dysplasia of the hip for several years. If diagnostic criteria are well established, the use of sonography in follow-up of treated infants remains extremely variable. The aims of this study were (a).

Shortcomings of diuresis scintigraphy in evaluating urinary obstruction: comparison with pressure flow studies.

Background: In at least 15 % of dilated urinary tracts, diuresis renography fails to assess the presence or absence of urinary obstruction.

Objective: To determine the shortcomings of (99 m)Tc-DTPA frusemide diuresis renography by reference to pressure flow studies.

Materials And Methods: Thirty-four patients, aged 1 month to 20 years, with questionable obstruction were evaluated by diuresis renography and pressure flow studies (the Whitaker test) as the reference method during the same short period of time.

[Evolution and radiologic surveillance on community-acquired pneumonia in children].

Although useful for the diagnosis of lower respiratory tract infections, chest X-rays have a weak specificity in the etiological diagnosis. It is of particular interest when complications are suspected. A radiological follow-up allows to exclude sequellae or a preexisting pulmonary abnormality; however follow-up X-rays are to be delayed 2 to 3 weeks after the clinical recovery due to the late radiological recovery.

Renal sinus hyperechogenicity in acute pyelonephritis: description and pathological correlation.

This paper reports on the association between renal sinus hyperechogenicity and acute pyelonephritis. The medical records and imaging studies of 18 children displaying this pattern were retrospectively studied. Thickening of the renal pelvis and renal enlargement were the most frequent associated sonographic abnormalities.

[Retrograde cystography after a first episode of acute pyelonephritis in the child and adolescent].

In spite of its invasiveness, voiding cystourethrography remains the gold-standard examination for detecting vesico-ureteric reflux. The aim of this study was to determine if voiding cysto-urethrography is useful at any pediatric age in girls after a first acute pyelonephritis. 152 patients have been retrospectively studied.

Idiopathic varicocele in children and adolescents--which therapeutic choice?

61 children were studied and treated between January 1986 and September 1993 for idiopathic varicocele. The aim of our study was to evaluate the advantages and disadvantages of the different techniques and to show the progression to a greater efficacy. The mean age at the time of therapy was 14 years, ranging from 7 to 16 years.

[Postnatal echography and cystography after prenatal diagnosis of minor dilatation of the kidney pelvis. Prospective study of 89 cases].

We evaluated postnatal management after the prenatal diagnosis of moderate dilatation of the renal pelvis (antero-posterior diameter superior to 1 mm per month of pregnancy and inferior to 15 mm at full term). Eighty-nine neonates who had a moderate dilatation in utero were evaluated by ultrasound and voiding cysto-urethrography. Ultrasound was performed between day 2 and day 7 in 83 cases, after day 7 in 6 cases.

[Sedation with oral hydroxyzine and rectal chloral hydrate in pediatric MRI and CT].

Aim: To assess the efficacy and risks of oral hydroxyzine and rectal chloral hydrate to sedate children undergoing CT or MRI.

Patients And Methods: 110 children underwent 117 studies. Medical history, treatments, doses per kg of sedative drugs, study quality, sedation time and side effects were prospectively recorded.

[Selective indications of skull radiography after head injury in children].

Purpose Of The Study: Skull X-rays are systematically performed on children after head injuries in most hospitals. However, the discovery of a skull fracture as an isolated finding rarely warrants intervention. In february 1994, we stopped performing systematical skull X-rays in children after head injuries.

[Perirenal necrotic and cystic pseudotumors in children. Report of two cases].

This work describes two cases of necrotic, encysted pseudotumors of unknown origin, in children; the lesions located on the anterior side of the kidney, near its inferior pole were remarkable for their size and their numerous adhesions to adjacent structures. The hypothesis of an initial infectious or tumoral mechanism are discussed, particularly the similarities supported by both lesions with the regressive patterns of some neuroblastomas.
