[Pediatric lymphomas diagnosis after needle biopsy in Abidjan: value of cytology versus MYC translocation examination].

Objectives: In Africa, lymphomas are widely represented by pediatric Burkitt lymphomas. In Abidjan, cytology performed after needle biopsy may be an examination of choice for pediatric lymphomas because of its low cost. We evaluated the value of this cytological examination in comparison with MYC rearrangement assessment.

[The uteropelvic junction in children: from the clinical problems to the morphogenetic approach].

The responsibility of the uteropelvic junction (UPJ) syndrome or abnormalities for renal affections and also for high obstructive uropathy is well-known. But, controversies still remain about the anatomic approach of this clinical feature. Our purpose is to elucidate the developmental anatomy of UPJ and eventually to set the steps of the anatomic approach of the UPJ abnormalities.
