[Intracytoplasmic crystals and Fanconi syndrome in a patient with IgA kappa myeloma]

A 45 year old man with IgA-Kappa myeloma had adult Fanconi Syndrome. Examination of renal biopsy revealed lesions in proximal tubules without glomerular lesions and without intratubular casts. By electron microscopy cytoplasmic crystalline inclusions were observed in renal proximal tubular epithelium. Increased plasma cells (28%) in bone marrow aspiration also contained crystalline inclusions. The treatment of myeloma produced partial remission of proliferative disease and Fanconi syndrome. We discuss the pathogenesis of Fanconi syndrome induced by light chains as well as the composition of crystalline deposits and the effects of treatment on Fanconi Syndrome.

[Efficacy of the CO2 laser in partial glossectomies]

In the present work, the authors show their experience in tongue surgery with Co2 laser. Two different kinds of partial glosectomies were made in several cases, CO2 laser was used on the right side, and conventional methods on the left side as a comparative group. Histological studies were made between both sides, in order to find differences in normal hemostasy and tissue response.
