background: due to difficulty of obtaining a 24h urine (especially in children), a random urine calcium sample is recommended to detect of hypercalciuria. however, recent studies have shown that the urinary calcium/creatinine ratio varies with age and geographic areas. so, the aim of this study was determining the normal value of urinary calcium to creatinine ratio in healthy adolescent’s child...

OBJECTIVE To evaluate the short term clinical effects of delayed cord clamping in preterm neonates. DESIGN Randomized controlled trial. SETTING A tertiary care neonatal unit from October 2013 to September 2014. PARTICIPANTS 78 mothers with preterm labor between 27 to 316/7 weeks gestation. INTERVENTION Early cord clamping (10 s), delayed cord clamping (60 s) or delayed cord clamping (60...

SYNOPSIS Two patients with phaeochromocytoma having atypical biochemical features are described. Total catecholamine excretion was normal in one and only slightly raised in the other; both had a diagnostic rise in output of metadrenaline and 4-hydroxy-3-methoxymandelic acid whilst 4-hydroxy-3-methoxyphenylglycol excretion was increased in one of them. During hypertensive attacks adrenaline excr...

Angiotensin I converting enzyme inhibitors are typically classified as peripheral vasodilators. We studied the effect of captopril and a known vasodilator, hydralazine, on arterial pressure-urinary output relationships in adult spontaneously hypertensive rats to determine whether these drugs produced similar changes in this relationship. Tail-cuff pressure and 24-hour urine output and sodium ex...

conclusions vur might be more frequent in children with physiological urinary incontinence than the normal population, and might be as common as nmne with intermittent daytime incontinence. results urinary tract infection was found in 23 (34.8%) children, 17 (33.3%) and 6 (40%) patients with nmne and physiological urinary incontinence, respectively. out of 48 patients who underwent vcug, vesico...

In both normally hydrated and volume-expanded rats, there was a biphasic effect of corticotropin-releasing hormone (CRH) (1-10 microgram, i.v.) on renal function. Within the first hour, CRH caused antidiuresis, antinatriuresis, and antikaliuresis together with reduction in urinary cGMP output that, in the fourth hour, were replaced by diuresis, natriuresis, and kaliuresis accompanied by increas...
