[Renovascular hypertension in childhood].

One to two per cent of children and up to 11% of adolescent have arterial hypertension. In most cases children and adolescent are not recognized to be hypertensive because physicians do not routinely measure blood pressure. Often the diagnosis is recognized only when the pediatric patients develop a complication: seizure, stroke, heart failure or paraplegia.

[Techniques of celiac plexus block and clinical results].

Coeliac plexus neurolesion techniques for pain due to upper abdominal cancer (pancreas cancer above all), have changed during the years. In this paper we report the results of coeliac plexus alcohol neurolysis for cancer of pancreas and of other abdominal organs achieved with the different techniques. It appears that precrural techniques provide very favorable results but they require the use of CT scan.

[Diffusion of contrast media in relation to different techniques of celiac plexus block].

The aim of this work was to evaluate--reviewing CT images--the spread of contrast medium injected following the different techniques of coeliac plexus block. We point out that the spread of c.m.

[Transureteroureteroanastomosis in children. Indications and results].

Transureteroureterostomy is a method of internal urinary diversion available to maintain the integrity of the urinary system, when the lower ureter is compromised. The usual requirements are a donor kidney with a minimal renal function on one side and a normal contralateral recipient kidney and ureter. From January 1972 to October 1988 in our Division transureteroureterostomy has been done in 52 children.

[Long=term evaluation of renal damage in primary vesico-renal reflux after corrective surgery].

Traditionally 3 mechanisms are responsible for the development of renal damage when primary vesico-renal reflux is present: reflux is a manifestation of abnormal embryological development of the ureteral bud, with subsequent dysplasia; sterile reflux damages the kidney, perhaps trough a mechanical or/and an immunological mechanism; renal damage occurs as a result of the reflux of infected urine into susceptible renal papilla (intrarenal reflux). Whatever the mechanism, it is apparent that reflux and renal damage are intimately related. It does appear that for the most part damage is done at an early age.
