[Rectal localization of Burkitt's lymphoma]. / Lymphome de Burkitt de localisation rectale.

BACKGROUND: Rectal tumors are rare in childhood and among them malignant tumors are even less common. Only eight cases of primary rectal lymphomas were reported in children, with various presenting signs and histology. Burkitt's lymphomas are among these cases. CASE REPORT: A five-year-old child presented with hematochezia and unusual constipation. The rectal examination showed a voluminous intra rectal mass. Radiographic and pathologic examinations led to the diagnostic of Burkitt's lymphoma with medullary involvement. Complete remission was obtained after initial chemotherapy but a local relapse occurred and the child died eight months later. CONCLUSION: Hematochezia associated with unusual constipation impose a rectal examination. Early diagnosis of a rectal tumor may allow patients survival.

[Continent urinary diversion using a tubulized sigmoid segment. An alternative to trans-appendicular diversion]. / Dérivation urinaire continente par segment sigmoïdien tubulisé. Une alternative à la dérivation trans-appendiculaire.

OBJECTIVE: The authors propose the use of a sigmoid tube reimplanted submucosally in the bladder and brought out onto the skin in the midline or in the umbilicus as a method of continent urinary diversion allowing urinary catheterization several times a day when the appendix cannot be used. MATERIALS AND METHODS: Three adolescents with neurogenic bladder were treated according to this procedure; the summit of the sigmoid colon loop was selected to form a continent tube from a segment 4 cm wide, opened along its antimesenteric border and sutured longitudinally. RESULTS: The postoperative course was uneventful in all 3 cases. The cystostomy was continent. Catheterizations were easily performed. CONCLUSION: Creation of a sigmoid tube is an alternative to the use of the appendix for continent urinary diversion according to Mitrofanoff's procedure. This technique can always be performed due to the proximity of the sigmoid colon and bladder, which is not always the case with the appendix. This tube is richly vascularized and presents the advantage of a very narrow mesocolon which does not interfere with creation of the intravesical submucosal tunnel.

[Modified Dyplay technique in the treatment of anterior hypospadias. Immediate and long term results in 321 cases and review of the literature]. / Technique de Duplay modifiée dans le traitement de l'hypospadias antérieur. Résultats immédiats et à long terme à propos de 321 cas et revue de la littérature.

OBJECTIVES: Description of a surgical technique in the treatment of anterior hypospadias, a frequent malformation for which the treatment is not devoid of complications. Evaluation of the short-term as well as the long-term results. MATERIAL AND METHODS: Retrospective study of 321 patients treated according to this method. 58 patients were reviewed with a mean follow-up of 71 months. RESULTS: The immediate results were marked by the development of 16 fistulas (5%), 4 of which closed spontaneously. Five cases (1.6%) of meatal retraction and 6 meatal stenoses (1.9%) were observed. The overall complication rate requiring specific treatment was 5.6%. The long-term results showed meatal retraction in 20.7% of cases, meatal stenosis in 1.7% of cases and fistula in 3.5% of cases. This is the series with the longest mean follow-up. Comparison with the currently proposed technique suggests that this technique is indicated in the treatment of anterior hypospadias. Long-term analysis of the results strongly encourages regular and prolonged follow-up of children treated for hypospadias in the first 2 years. CONCLUSION: The modified Duplay technique is reliable, can be easily performed, and gives perfectly satisfactory results, even in the long-term, for the treatment of anterior hypospadias.

Inflammatory pseudotumor of the retroperitoneum in a child.

Inflammatory pseudotumor is a rare, benign lesion of various organs and tissues that occurs in children and young adults. A case is reported in a 12-year-old boy in a retroperitoneal location with involvement of the left ureter and a thrombosis of left iliac vein. He underwent surgical resection. A local recurrence 6 months later was surgically cured.

Atlanto-axial dislocation due to ossiculum terminale persistens. Report of two cases treated by a new technique of posterior fusion.

Two cases of atlanto-axial dislocation due to ossiculum terminale of the odontoid process are reported. A new technique of posterior fusion with a Y-shaped plate is described. Embryological data, clinical features, and operative treatment of this unusual condition are discussed.

A new technique of bladder enlargement and continent urinary diversion using the ceco-appendicular unit.

The authors developed a new technique using the cecum with in-situ appendix to simultaneously achieve bladder enlargement and continent urinary diversion (CUD) in five cases of neuropathic bladder or serious complications of abdominopelvic trauma. The cecoplasty provides a large-capacity, low-pressure reservoir; the submucosally-embedded appendix gives complete continence with 3 to 5 intermittent catheterizations daily. It is an alternative to the Mitrofanoff principle when bladder augmentation and CUD are necessary, and easier to achieve when faced with a neuropathic bladder where the thickness of the detrusor makes appendicular implantation difficult.

[Acute intestinal intussusception: ultrasonic diagnosis and air insufflation]. / Invagination intestinale aiguë: diagnostic échographique et réduction pneumatique.

Sixty-five children with intussusception were diagnosed by ultrasonography. Colonic air insufflation was the principle form of treatment. The diagnosis value of ultrasound was 100% and the success rate of reduction by air insufflation was 93%, after intrarectal injection of midazolam (0.3 mg/kg). The device for insufflation was simple, original and manual, with permanent control of intrarectal pressure. No complications were observed.
