[Bartter's syndrome in children and adults. Study of 6 cases].

Six patients (3 children and 3 adults) with the clinical and biochemical features of Bartter's syndrome are presented. Pediatric cases included a more severe form, in one patient, with physical and mental retardation, hypercalciuria and nephrocalcinosis, and a less severe one, including two patients, with milder clinical features, low calcium and high magnesium excretion and hypomagnesiemia. Adult patients were affected by either the mild congenital form (case n. 4) or the acquired variety (cases n.5 and 6). Tubular function was investigated in the 3 adults by assessing clearance measurements during maximal diuresis. There was a defective fractional distal solute reabsorption (FDR) ranging between 0.52 and 0.60. This was well below the results obtained in one patient with psychogenous vomiting (FDR 0.94) and comparable to those in two patients with interstitial nephropathies caused by vesico-ureteral reflux (FDR 0.63 and 0.67 respectively). We concluded that: 1) the etiopathogenetic spectrum of Bartter's syndrome corresponds to different clinical presentation (mild, heavy, congenital or acquired varieties), and alterations in mineral and electrolyte renal handling; 2) reduction in FDR is a feature neither essential nor exclusive of this syndrome.

[Dosimetric experience with mammography].

Dose measurements were carried out during mammography with both conventional films without a reinforcement screen and with Low-dose films, using hot press chip lithium fluoride meters on the breast, sternum, mons Veneris, and the glabella between the supraciliary arches. The results made it clear that there were no dosimetric objections to the large-scale employment of mammography in diagnosis. Value absorbed were lower than those given in the literature for both the conventional and the Low-dose system.

[Arterial pressure in childhood. I: Relation to age. (collection of data relative to 3,737 pupils of elementary and high school between the ages of 6 to 14 years)].

Research relating blood pressure levels of 6-14 years-old age schoolchildren has been carried into the whele school-population of Chivasso (Turin) town. Three kinds of armbands of different widths and lengths were used according to age. In conformity with Long's suggestions, the correction factors were used for the age-groups from 6 to 7 years and 8 to 11. On the grounds of the levels taken the quantiles were calculated. The graphs show the shape of the 5th, 25th, 50th, 75th, and 95th percentiles, related to the systolis and diastolic pressures and to the age of the child. The results showed a continous increase in the shape of the levels, which did not depend on the sex variant. A spike in the 9th year can be related to the fact that the correction factor can be less than it should be. The decrease in the 11th year can be put down to the fact that the correction for the armband has not been carried out from the 12th year onwards. 6.52% of schoolchildren have systolic and/or diastolic blood pressure greater than 95 degrees C.

[Bladder neck and urethral obstructions in childhood. Radiological study (review and personal case reports)].

In the first part the authors report a nosological review of the obstructions of the bladder neck and urethra in childhood and present the most typical radiological aspects of the most important obstructive uropathies. In the second part they illustrate their cases, that include 11 patients between 0 and 10 years, of which 4 males, with urethral valves; 2 females, with external urethral meatus stenosis; 1 male, with non valvular stenosis of urethra: 2 one male and one female, with extrinsic obstruction by ectopic ureterocele; and 2 females, with neurologic bladder. The authors point out the cases with obstruction by posterior urethral valves and by ectopic ureterocele, mainly for the severe hydrodynamic effects of low obstruction on bladder, ureters and pelvis; the authors present, in some cases, also later radiological examinations, obtained after surgical removal of the obstruction. The two cases of neurological bladder are presented in order to point out the difficulty of an exclusively radiological differential diagnosis between some cases of true mechanical obstruction and obstruction caused by neuromuscular disorder of low urinary tract. At last the Authors confirm again the usefulness, but also the limits, of the radiological examination alone in diagnosis of the obstructions of bladder neck and urethra in childhood.
