During ceftriaxone treatment of subdural empyema caused by Streptococcus intermedius urinary and biliary stones were noticed. Increased levels of urinary calcium excretion were detected during ongoing treatment in comparison with 2 months check-up. There were no significant changes in the promoter/inhibitor urolithiasis parameters, oxalate, citrate, urate, cistine, glycosaminoglycans or their ratios. Urine saturation was calculated using EQUIL 2 computer programme (calcium oxalate, brushite) and it was normal. Probable trigger for the ceftriaxone/calcium hydroxy carbonate phosphate mixture of stones was a critical boost of solubility products caused by ceftriaxone treatment and phospnate urine content with a subsequent large-scale spontaneous precipitation of crystals.
A severe hypertension was found in a 9 month old boy with signs and symptoms of severe arterial hypertension. An upper left branch renal artery stenosis complicated with multiple thrombosis and cardiac hypertrophy was diagnosed. Surgical heminephrectomy of the upper pole of the left kidney was successful in blood pressure normalization with significant improve of cardiac function and thrombosis recanalization.
