ABSTRACT
OBJECTIVE: To determine: (i) the proportion of vesicoureteric reflux (VUR) associated with congenital renal damage and whether it can be severe enough to cause renal impairment from birth: (ii) to evaluate the distribution of males and females affected; and (iii) to describe the course of congenital damage in the first years of life. PATIENTS AND METHODS: A total of 108 children (76 male and 32 female, M:F 2.3:1), whose VUR was diagnosed before any infection, were followed from birth for a mean (range) of 4.3 (1-10) years. Renal damage was defined by serum creatinine concentration, creatinine clearance and renal imaging (ultrasonography and renal scintigraphy) performed within the first month of life and periodically thereafter. RESULTS: Of the 108 children, 58 had bilateral and 50 unilateral reflux (total number of refluxing units, 166). High-grade VUR (grade > or = 4) was found in 96 (58%) refluxing renal units (RRUs). Males had a prevalence of bilateral severe (> or = grade 4) reflux (M:F 5.2:1), while in those wit unilateral VUR, the M:F ration was 1.5:1. At birth, mild to moderate damage was present in 56 (36%) RRUs and only associated with VUR of grade > or = 3. Bilateral reflux of grade > or = 4 was associated with congenital moderate/severe renal failure in nine neonates (seven males). In infants with grade > or = 4 VUR who underwent surgical correction, VUR resolved in 92% of cases. In infants with VUR of grade > or = 4 followed medically, the reflux spontaneously resolved in 42% and ameliorated in 16% after 18 months. Serial renal scans during the follow-up showed no progression of renal damage. CONCLUSIONS: VUR diagnosed at birth on prenatal ultrasonography is associated with congenital damage, with males affected more often than females. The damage involves both kidneys in a consistent proportion and is an important cause of chronic renal impairment from birth. It does not progress in the first years of life if infections are prevented. It is suggested that males with this condition may constitute a major group at risk of developing chronic renal failure in later life.

A case is reported of ganglioneuroblastoma in a 5-year-old boy, who had urticaria syndrome by physical agents (water, light, cold) in the last 2 years, associated with an apparent splenomegaly. A sonography and a CT scan showed a large cystic mass with calcification near the left kidney. After surgery, it was possible to diagnose left adrenal ganglioneuroblastoma (Evans's first stage). Complete regression of urticaria syndrome was obtained after mass removal.

Circulating IgA-antigliadin antibodies were detected with enzyme linked immunosorbent assay (ELISA) in four of 121 patients (3%) who had IgA mesangial nephropathy and 14 of 17 children (82%) who had untreated coeliac disease. No positive cases were present in the 54 healthy subjects of the control group. Three patients who had IgA nephropathy and IgA-antigliadin antibodies underwent jejunal biopsy, and two showed mucosal atrophy. In these two patients urinary abnormalities, together with the IgA-antigliadin antibodies, disappeared completely after three months and five months, respectively, of following a gluten free diet. Circulating IgA immune complexes were found in most patients who had coeliac disease and Berger's disease associated with IgA-antigliadin antibodies, suggesting overactivity of the B cells producing IgA in both conditions. By contrast, a circulating IgA rheumatoid factor was detectable in three of the four patients who had IgA nephropathy and asymptomatic coeliac disease but was always absent in children who had coeliac disease but did not show signs of renal disease. These results suggest that a more complex abnormality in the IgA immune response is necessary for renal disease to become manifest in patients who have gluten enteropathy.

Kawasaky's disease is a multisystem widespread vasculitis. Besides the mucocutaneous patterns, symptoms related to various organs have been observed in the medical literature. Lethargy, irritability, meningism and cranial nerves paralysis occur in the acute phase of central nervous system involvement. The A.A. report a rare cerebellar syndrome caused by vasculitis in a seven years old girl's cerebellum. Surveillance of tardive complications must be undertaken in patients affected by Kawasaky's disease.
