Because the syndrome of inappropriate antidiuretic hormone (SIADH) is a state of disturbed body fluid volume regulation and altered sodium balance we sought to determine if recently described volume regulatory factors were stimulated in SIADH. We measured atrial natriuretic peptide (ANP), endogenous digitalis-like natriuretic factor (EDNF) and urinary free(More)
Lichen striatus (LS) is a benign, self-limited, linear, inflammatory dermatosis of unknown etiology that usually affects children. We analyzed 89 cases in regard to age of appearance, sex, race, symptoms, seasonal incidence, localization of lesions and affected side of the body, and presence of atopy. Lesions predominated on the inferior limbs, with no(More)
Distal renal tubular acidosis has been reported as an uncommon cause of urinary calcium stone disease. However, this defect appears to be more frequent when appropriate tests are performed systematically. Twenty-nine patients with recurrent calcium stones have been separated into three groups: normocalciuric (group A), renal hypercalciuric (group B) and(More)
The purpose of this study was to measure changes in serum atrial natriuretic factor concentrations immediately after heart operations in children under baseline conditions and in response to continuous infusion of dopamine (2.5 and 5.0 micrograms/kg/min). During control periods, levels of atrial natriuretic factor were elevated at 190 +/- 24 and 199 +/- 36(More)
As there are controversies about the specificity and the sensitivity of the amylase clearance/inulin clearance ratio (Cam/Cin) in the diagnosis of pancreatitis, this ratio has been calculated: (a) in rats with induced pancreatitis with histologically proven lesions; (b) in toxic induced tubulopathy rats with lesions demonstrated histologically and(More)
