Familial hypouricaemia due to an isolated tubular defect of urate reabsorption.

Hypouricaemia due to an isolated renal tubular defect is a rare condition. Several members from an affected family are described. The propositus is a 12-year-old girl with hypouricaemia (0.7-1.1 mg/dl) and increased fractional excretion of uric acid (50%). Pyrazinamide and sulphinpyrazone tests revealed an attenuated response in this subject to both drugs. The mother and one of the propositus' two brothers have the same defect. The other brother has uric acid levels at the lower limit of normal and increased fractional excretion of uric acid. These results suggest familial hypouricaemia due to a pre-secretory reabsorptive tubular defect, transmitted by autosomal dominant inheritance.

[Infrequent manifestations of Henoch-Schonlein purpura].

We review the cases of 148 children with Henoch-Schönlein purpura diagnosed in a period of seventeen years (from 1975 to 1992). Thirteen cases (8.7%) of unusual clinical manifestations were found: testicular affection in six cases (7.6% of the males); IgA nephropathy in four (2.7%); exudative enteropathy in two (1.3%); duodenal syndrome in two; previous abdominal manifestation which led to surgical procedures in one (0.7%) and another case with detachment of the retina. These clinical findings are analyzed and the possibility of unnecessary therapeutic acts is discussed.

[Guide for the prevention of renal diseases during and after childhood].

Kidney disease Prevention in childhood can be made from three levels. In the first level or Primary Prevention one must prevent kidney disease taking steps for "Kidney Health" promotion: environmental factors, nourishing, sanitary education and preventive pediatrics. Secondary Prevention lies in the correct diagnostic during first years in life and in a suitable treatment of the kidney diseases, especially in children to have a kidney failure risk: obstructive uropathy and vesicoureteral reflux. Tertiary Prevention deals with aggravating factors in an established Kidney chronic failure, and its prevention includes: normoproteic diet, phosphorus restriction, arterial hypertension control and nutritional and pharmacological steps to reduce the hyperlipidemia.

[Parathyroid insufficiency syndrome. Two new cases: type Ia pseudohypoparathyroidism and pseudo-idiopathic hypoparathyroidism].

Two new cases with parathyroid insufficiency syndrome are described. The first one is a seven year and 6 months old male with Pseudohypoparathyroidism Type Ia, who has presented: hypocalcemia, hyperphoforemia, increased PTH and TSH, prolactin decreased and Albright hereditary osteodystrophy phenotype. The second one in a six year and four months old female with Pseudo-idiopathic hypoparathyroidism who has presented: hypocalcemia, hyperphosforemia, increased PTH, without any hormonal disturbances nor dysmorphias. Ellsworth-Howard test with 50 micrograms of 1-34 hPTH is made in both, remarking the different renal response about phosphaturia and plasmatic, urinary and nephrogenic cyclic AMP. The treatment is performed in both with calcitriol and oral calcium (L-Thyroxine is associated for the first patient). Biochemical disturbances are normalized. Other parathyroid insufficiency syndrome are revised.

[Screening of urinary tract. infection using the dip-strip method with 770 school girls (author's transl)].

The results of a significative bacteriuria detección programme with a group of 770 girls between 6 and 14 years old using culture method of dip-strips which have to be inoculated, incubated, and read by health officers, are shown. This method has proved to be efficient in the detección of significative bacteriuria in big towns and of low cost if it is compared with other methods.

[Infantile nephrosis. Microcystic renal disease (author's transl)].

Two siblings, male and female with nephrotic syndrome of neonatal onset are reported. Both parents were healthy as well as another 5 year-old brother. Both died under two months. Their clinical, biochemical and immunological data are described, and the more common causes of N.S. (i.e. syphilis, toxoplasmosis, tuberculosis) ruled out. Pathology was available only from one of the cases, and the lesions were comparable to those described by finnish authors as corresponding to "congenital" N.S. This report is an additional evidence of the presence of this entity out of Finland.

[Bladder calculus formed on chromic suture].

This is a description of a clinical case of a two-and-a-half year old male child who developed a urinary bladder stone seeded on chromic catgut used to suture of the bladder wall which was damaged in the course of the surgical repair of an inguinal hernia.
