a list of 28 patients is given in whom the duration of the sore at the site of leishmanization has been 3 to 7 years. the problem of cases of cutaneous leishmanjasis with long duration as a complication of leishmanization is discussed. although this complication is very rare, i.e. a few hundreds among more than 2 million people inoculated, its effect on the leishmanization program has been cons...

Primary rhabdomyosarcoma (RMS) of the kidney is a rare malignant mesenchymal tumor with an aggressive clinical course. Adult renal RMS is typically a pleomorphic histologic subtype and only a few cases have ever been reported. We herein present a new case of renal RMS of the embryonal histologic subtype in a 26-year-old woman.

A brief review is presented of the stability domain of threeand fourcharge ground-states when the constituent masses vary. Rigorous results are presented, based on the scaling behavior and the convexity properties deduced from the variational principle. They are supplemented by accurate numerical computations. Talk given at the Workshop Critical Stability, Les Houches, Oct. 8–12, 2001, to appea...
