[Cystic ectasia of the rete testis: apropos of a case].

We report a case of a simple testicular cyst developing on the rete testis. Nine cases have been reported in children. In our patient, the cyst was associated with aplasia of the homolateral kidney and termination of the left ureter in the left deferens. According to the literature, the diagnosis is usually fortuitous at histology examination. The cause is probably embryonic malformation. Castration is the therapeutic solution. In our case, simple enucleation allowed preservation of the deferens since the controlateral tree was damaged. There have been no complications with a 6-year follow-up.

[Urothelial tumor of the bladder in children].

A papilloma of the bladder was discovered in 10-year-old child who presented with haematuria. The review of the literature from 1955 produced 131 similar cases. The particular situation of this usually adult tumour in paediatric patients was emphasized by this case and those reported in the literature: good prognosis, rare invasion, lower rate of recurrence than in the adult and habitual effectiveness of endoscopic resection.

Antley-Bixler syndrome: case report and review of the literature.

A female newborn presenting a malformative syndrome which groups trapezoidocephaly, midfacial hypoplasia, radiohumeral synostosis, multiple joint contractures and femoral bowing is described as being affected of an Antley-Bixler syndrome. We compare this case with the seventeen others cases reported.

[Median cleft of the upper lip. Apropos of 3 cases. The Association for the Study of Facial Clefts].

The authors report three cases of Median Cleft of the upper lip, a clinical entity really deserving the term of "hare lip", a very ancient denomination who dates back to the Tang Dynasty and unfairly used to describe the usual lateral clefts of the lip. The denominations of "true" and "false" median cleft lips recovering respectively such different embryopathic realities as clefts of the median element with varying degrees of vertical separation and as agenesis of the fronto-nasal process accompanied with cerebral anomalies are no more used now. Median clefts of the upper lip can be included in the "neurocristopathies" by less or more precocious dysneurulation of the fronto-nasal process creating anomalies from various single midline defects of the upper lip of our three cases, to associated midline defects like in the Median Cleft face syndrome (fronto-nasal dysplasia) described by De Myer and Sedano to holoprosencephaly (arhinencephaly), which are rarely associated.

[First-choice orthopedic treatment in congenital hip dislocations discovered after walking age].

The incidence of late discovery of congenital dislocation of the hip is getting lower, thanks to systematic screening. We have treated 14 children during the past 5 years. Clinical diagnosis was confirmed by radiography. Thirteen children were treated by slow reduction, and immobilization according to Somerville-Petit's method. Four surgical treatments were performed (1 Klisic operation by first intention, 3 Salter operations by second intention). Good clinical results have not always correlated with radiologic normalization. These results were evaluated by Séverin's classification: 9 excellent or good (I or II), 4 poor results (III). Although improvement is expected in the future, repeated clinical and radiological supervision permits evaluation of the indications for a subsequent operation at the most favorable time.

[Chronic diarrhea caused by VIP-secreting ganglioneuroblastoma in children. Apropos of a case with a review of the literature].

A literature review was conducted in relation to a case of chronic diarrhea associated with a VIP (vasoactive intestinal polypeptide) producing ganglioneuroblastoma (GNB), in an 18-month old female baby. This is a rare entity characterized by premonitory, persisting diarrhea, causing fluid and electrolyte changes typical of the WDHA syndrome, associating watery diarrhea, hypokalemia, and achlorhydia. Elevated VIP plasma levels are an indication for an echographic and/or CT-scan search for the causal secreting tumor. Although the prognosis of this condition seems favorable, the recommended treatment is surgery. The VIP substance represents an excellent biological monitoring marker. Ganglioneuroblastomas are tumors of the sympathetic nervous system, which, according to Pearse's cell and embryologic theory (1966), have to be linked to the APUD system tumors (paraneuromas). VIP-producing forms are rare in children, and only 29 case studies have been compiled in the literature since 1970, when the VIP substance was discovered. The case reported in this study illustrates the diagnostic problems raised by such lesions, and allows us to confirm VIP's imputability for the occurrence of the chronic diarrhea condition in this child.

[Neonatal pulmonary fibrosarcoma].

The authors report a case of pulmonary fibrosarcoma in a newborn. The respiratory distress imposed an urgent thoracotomy at the fifth hour of live. A lobectomy was performed. Three months later a relapse occurred. A second thoracotomy permitted an incomplete resection. The total involution was achieved after 6 months of chemotherapy. Actually no recidive is shown after 20 months of follow up. Its an exceptional case. A unique one was published in 1977.

[Stenosis of the ureter in the development of Crohn's disease].

The authors report the exceptional case of a young boy, 14 years old, affected by Crohn's disease, first treated medically. Extension and aggravation of injuries required right hemicolectomy. An obstruction of right ureter appeared, diagnosed by echography. The investigations showed up a stenosis of right ureter. A resection-suture was performed and the follow up at two years in good.
