Encapsulating peritoneal sclerosis in paediatric peritoneal dialysis patients: the experience of the Italian Registry of Pediatric Chronic Dialysis.

Background: Paediatric literature about encapsulating peritoneal sclerosis (EPS) is limited and comes primarily from anecdotic experiences. In this study, we described the incidence and characteristics of EPS in a large paediatric chronic peritoneal dialysis (CPD) patient population.

Methods: We reviewed files of patients starting CPD at <16 years of age, recorded from January 1986 to December 2011 by the Italian Registry of Pediatric Chronic Dialysis (n = 712).

Hemolytic uremic syndrome and rhabdomyolysis in a patient with succinate coenzyme Q reductase (complex II) deficiency.

Hemolytic uremic syndrome (HUS) is characterized by microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure. Besides diarrhea-associated HUS, due to verotoxin-producing Escherichia coli, in children HUS without prodromal diarrhea may be associated with other infectious and autoimmune diseases, genetic defects of the complement-regulator alternative-pathway, and inborn errors of vitamin B12 metabolism. Rhabdomyolysis is the dissolution of skeletal muscle due to various causes, including inborn errors of metabolism.

Peritoneal dialysis in infants: the experience of the Italian Registry of Paediatric Chronic Dialysis.

Background: Although chronic peritoneal dialysis (CPD) is considered the replacement therapy of choice for infants with end-stage renal failure, many questions persist about treatment risks and outcomes.

Methods: We present data on 84 infants who started CPD at <1 year of age; these patients represent 12% of the total population of the Italian Registry of Paediatric Chronic Dialysis. We analysed patient records from all children consecutively treated with CPD between 1995 and 2007 in Italy.

Hemolytic uremic syndrome: epidemiological and clinical features of a pediatric population in Tuscany.

We retrospectively analyzed etiological, pathological and clinical features of the patients with hemolytic uremic syndrome (HUS) observed in the Pediatric Nephrology Unit at AOU Meyer of Florence. From January 1997 to December 2008, 22 cases were identified, with an annual incidence of 0.05 cases per 100,000 inhabitants, and 0.

Inner ear abnormalities in four patients with dRTA and SNHL: clinical and genetic heterogeneity.

A significant number of patients affected by autosomal recessive primary distal renal tubular acidosis (dRTA) manifest sensorineural hearing loss (SNHL). Mutations in ATP6V1B1 are associated with early onset SNHL, whereas ATP6V0A4 mutations have been described in dRTA and late-onset SNHL. Enlarged vestibular aqueduct (EVA) was described in patients with recessive dRTA and SNHL, and recently, this abnormality has been associated with mutations in the ATP6V1B1 gene.
