[Posterior urethral valves in children. Apropos of 22 cases].

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.

[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].

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.
