[Role of imaging in the management of abdominal trauma in children].

Blunt abdominal trauma is common in children and induces significant morbidity and mortality. Trends in management of solid viscera lesions have changed over the past 15 years and a conservative approach is now preferred whenever possible. Such management has become possible in selected cases due to advances in pediatric intensive care and medical imaging. The authors provide a review-based on international literature data-of the respective roles of medical imaging studies in the initial management of blunt abdominal trauma in children. The place of these investigations is discussed for each organ, with emphasis on the diagnostic value of sonography and computed tomography. Diagnostic pitfalls and limitations in prognostic accuracy are discussed.

[Analysis of the failure of endoscopic treatment of vesico-renal reflux in children using injections of teflon and collagen and the preliminary results of injections of Macroplastic].

This study of 785 cases of vesicorenal reflux in 494 children treated endoscopically over a 7-year period was designed to evaluate the results obtained with three products used successively: Teflon, collagen and Macroplastic. Following Teflon injection, despite a 90% short-term success rate, recurrent reflux was subsequently observed in 16.71% of the ureters reviewed. The failure rate was 52.63% after collagen injection and 11.77% after Macroplastic. After one or two injections, complete resolution of reflux was obtained in 48% of children treated with collagen, versus 85.72% with Teflon and 93.33% with Macroplastic. In one half of cases, failure was related to the quality of the product and its modifications after injection. The marked resorption of collagen accounts for the poor results despite the large doses injected. Apart from one case of partial resorption of Teflon paste, the failures with this product were due to lateralisation or secondary elimination of the product from the injection site due to its fluidity. Macroplastic, due to its higher viscosity and absence of retraction, currently provides the best results with doses of less than 0.20 ml in children.

Relapsing urinary ascites.

A 2-year-old boy was operated on for a left ureteral duplication with bilateral vesicoureteric reflux. Ten years later, he experienced two episodes of transient ascites following abdominal traumatism. A cystogram disclosed a peritoneal fistula. The fistulous orifice was localized by cystoscopy, and surgery was undertaken with success.

[Idiopathic retroperitoneal hematoma. Apropos of a case].

A 10 year-old girl presented with a progressive left ureteral colic with abdominal tenderness. Ultrasonography revealed pyelocalyceal dilatation and an intravenous pyelogram showed lateral deviation of the left ureter. Computed tomography confirmed retroperitoneal mass distinct from psoas. Laparotomy revealed an encapsulated retroperitoneal hematoma. No particular aetiology was found and the patient's health remained stable after treatment.

[Multicystic renal dysplasia. Spontaneous remission of a hypertrophic form].

A case of spontaneous regression of the tumor type of multicystic dysplastic kidney (MDK) is reported. This case is consistent with recent data on the natural history of MDK. The classical therapeutic approach which involves surgery is discussed in the context of this case and of others with a similar course.

[Transient dilatation of the intra- and extra-hepatic bile ducts. A new aspect of bile duct involvement in scarlet fever].

An extra- and intra-hepatic bile duct dilatation has been observed in a child in the course of scarlet fever. Manifestations of cholestasis, cytolysis and inflammation were present. Pruritus disappeared within 2 months, biological abnormalities within 3 months and ultrasonic bile duct abnormalities between 3 and 6 months, with a follow-up of 9 months. This case report suggests a relationship between a transitory obstruction, possibly toxic in origin, of the bile ducts and the scarlet fever.

Enterolithiasis in two neonates with oesophageal and anorectal atresia.

Enterolithiasis in two neonates with oesophageal and anorectal atresia is reported. The features of the two cases and comparison with the literature, the particular appearance of these intracolonic calcifications and the importance of radiological examinations for associated digestive, urinary and pulmonary malformations are presented.

[Extensive congenital stenosis of the bulbo-membranous urethra in a child. Apropos of a case discovered in a newborn infant].

A congenital atresia of the bulbo-membranous urethra had been reported. The atresia extended for 1.5 cm. It presented early in the neonatal period with major dilatation of the upper urinary tracts. After a preliminary urinary diversion, the surgical repair through the perineum was done at the age of 18 months. Such cases are not seen frequently. This atresia must be differentiated from posterior urethral valves type III, and from other stenoses either iatrogenic, traumatic, or inflammatory. The partial atresia is the only type compatible with life. It may be presented in two forms: annular constriction or extended stenosis. The mechanism of evolution is not very clear: it is either due to a bad resorption of the urogenital membrane or a defect in the embryogenesis of the urethral tube. Treatment differs according to the site and extent of the lesion simple dilatation, internal urethrotomy, or urethroplasty in one or several stages can be done.

[Surgical results of uretero-vesical reimplantations in children. Apropos of 356 cases in 11 years (629 reimplanted ureters)].

629 ureteric reimplantations were performed in 356 children. Indications for reimplantation were 315 uni or bilateral ureteral reflux, 248 primary reflux and 67 secondary to ureteric duplication, ureterocele, vesical diverticula, neurogenic bladder, bladder neck obstruction, or ureteral obstruction, and 52 megaureters, 38 primary and 14 secondary megaureters. 61 reimplantations (14 megaureters) by Leadbetter-Politano, and 568 reimplantations (58 megaureters) by Cohen procedure were performed. 3 psoas hitching and 15 ureteroplasties, 14 Hendren and 1 Kalicinski procedures, were necessary. Primary results in reflux were 98.5% of success with Cohen operation and 100% with Leadbetter-Politano operation. Results were not so good in megaureter, 70% of success with Leadbetter-Politano operation and 75% with Cohen. Results were better with psoas hitching and ureteroplasty (86.5% of success).

[Genitography of sexual ambiguities in children].

In children with pseudo or true hermaphroditisms genitography is easy to perform and reliable. This examination helps in determining the morphological sex and becomes necessary if surgery of the genital tract is considered.

Intracerebral myiasis in a child.

Larvae of Hypoderma bovis accidentally parisitize man. These larvae can penetrate into the brain by a path which remains unknown, causing an intracerebral haematoma and clinical signs. Computerized tomography shows the haematoma, and carotid angiography shows the absence of a vascular malformation, but these examinations do not allow etiological diagnosis. This is suggested by seroimmunological examinations and by the discovery of the larva during the operation. We report findings in a 6 1/4 year old boy.
