[Problematic management of tumors with a very high proliferation coefficient: a case of an embryonal rhabdomyosarcoma of the right orbit in an eleven-year-old child]. / Problèmatique de l'approche thérapeutique des tumeurs à coefficient de prolifération très élevé: a propos d'un cas de rhabdomyosarcome embryonnaire de l'orbite droit chez un enfant de 11 ans.

We propose through the retrospective analysis of this document, to explain the inefficiency of the action of chemo and radiotherapy on tumours with a high proliferation coefficient but which are however known to be highly sensitive as well as curable with chemo and radiotherapy. This study shows the technical conditions and dispositions for a better therapeutic approach in these tumours with a rapid growth.

[Posterior urethral valves in children. Apropos of 22 cases]. / Les valves de l'urètre postérieur chez l'enfant. A propos de 22 cas.

We reviewed 22 cases of posterior urethral valves over a five year period (January 1986 to December 1990). We looked at initial management before referral to the urologist, treatment and those factors that influence the outcome. We found that nosocomial infection from catheters was the major source of morbidity and mortality. Other determinants of outcome included postobstructive diuresis and the presence of refluxing or obstructing megaureters. The age of the patients was not as important as the degree of obstruction in this group of patients. We recommend percutaneous cystostomy as initial management for these patients as opposed to urethral catheterisation. This should be followed by antegrade or retrograde valve ablation one week later depending on the size of urethra.
