Is Bohr's correspondence principle just Hankel's principle of permanence?

No, but the paper argues that Bohr understood his correspondence principle, or at least an aspect of that principle expressed by the notion of rational generalization, as grounded in Hankel's principle of permanence, adapted to new historical and theoretical contexts. This is shown to illuminate some otherwise obscure aspects of Bohr's approach to quantum theory, as well as a seemingly strange criticism against this approach, due to Feyerabend and Bohm.

Splenic Tuberculosis--Case Report.

The authors advance the case of a patient aged 42, with cardiovascular disorders who is hospitalized for non-specific, but persistent symptomatology: asthenia, fatigability, dyspnoea, night sweats. The clinical (splenomegaly), abdominal ultrasonographic (splenic hypo-echogenic lesions) and computed tomographic (splenic hypo-dense lesions) elements lead to a splenic disorder, but the association of intra-thoracic and intra-abdominal adenopathies(CT revealed) raises suspicion of a chronic lymphoproliferative syndrome. Splenectomy by open approach is performed and the surprise comes from histopathology: splenic tuberculosis.
