ABSTRACT
Trace element contents in two copper minerals [brochantite [Cu(4)SO(4)(OH)(6)] and native Cu] using k(0)-NAA were determined before and after quantitative removal of copper. The distribution of 44 elements in the studied minerals was investigated. An important advantage of the proposed method is the possibility to determine the content of several elements (Al, Dy, Mg, Mn and V) via their short-lived nuclides after the electrolytic removal of Cu due to the elimination of matrix interferences.

We present a 5-year-old boy with pneumonia who complained of right lumbar pain on the 7(th) day of treatment with Ceftriaxone. Ultrasound examination revealed mild to moderate right hydronephrosis. Under spasmoanalgetic therapy and hydration there was spontaneous passage of three small calculi. Infrared spectroscopy showed that the calculi were composed of calcium-ceftriaxonate. Full metabolic investigation was performed and moderate hypercalciuria was detected, suggesting the role of hypercalciuria in ceftriaxone-associated nephrolithiasis.
