Abstract
Gout is recurrent inflammatory arthritis caused by the deposition of monosodium urate crystals in the joints. The risk factors that predispose to suffering from gout include non-modifiable factors such as gender, age, ethnicity and genetics, and modifiable factors such as diet and lifestyle. It has been shown that the heritability of uric acid levels in the blood is greater than 30%, which indicates that genetics play a key role in these levels. Hyperuricaemia is often a consequence of reduced renal urate excretion since more than 70% is excreted by the kidneys, mainly through the proximal tubule. The mechanisms that explain that hyperuricaemia associated with reduced renal urate excretion is, to a large extent, a proximal renal tubular disorder, have begun to be understood following the identification of two genes that encode the URAT1 and GLUT9 transporters. When they are carriers of loss-of-function mutations, they explain the two known variants of renal tubular hypouricaemia. Some polymorphisms in these genes may have an opposite gain-of-function effect, with a consequent increase in urate reabsorption. Conversely, loss-of-function polymorphisms in other genes that encode transporters involved in urate excretion (ABCG2, ABCC4) can lead to hyperuricaemia. Genome-wide association study (GWAS) methods have made it possible to locate new gout-related loci associated with reduced renal urate excretion (NIPAL1, FAM35A).

Abstract
Isaac Albéniz was a Spanish musician and pianist who was best known in France and England. One of his last works for piano, the suite Iberia, is well-known and identifies his country of origin. He died with terminal uraemia following longstanding chronic intestinal and kidney symptoms. Suggestions as to pathology include amyloidosis complicated by kidney stones and hypertension that sometimes manifested itself in the form of hypertensive crisis, accompanied by obesity.

Abstract
We studied 34 asymptomatic children who were born with a very-low-birth-weight (VLBW) and had no perinatal history of acute renal failure nor treatment with furosemide. The study was done at preschool or school age, looking for echographic changes and renal tubular disturbances which are known to predispose to renal lithiasis. The results were compared with those of a control group of 18 children who had been born at term with a body weight >2,500 g. One or more renal tubular disturbances were found in 64.70% of the VLBW children. Most frequently found were decreased ammonium excretion in response to furosemide (38.23%), enhanced N-acetylglucosaminidase excretion (35.29%), hypercalciuria (26.47%), and hypocitraturia (23.53%). Echography revealed renal cortical hyperechogenicity (17.65%) and renal lithiasis (8.82 %) in some of the VLBW children. We found a significant positive correlation (r = 0.7) between the perinatal level of plasma phosphate and the total amount of H+ excreted in response to furosemide at preschool or school age. Because these renal tubular anomalies may be precursors of future lithiasis, and the renal function and echography tests are not invasive, we suggest that renal tubular function be measured and followed up in every VLBW child, particularly when perinatal hypophosphatemia has occurred.
