BACKGROUND Inborn errors of cobalamin (Cbl) absorption and metabolism form a large group of rare diseases that include Cbl-C disorder. Among the renal complications of Cbl-C disorder, atypical hemolytic uremic syndrome (HUS) is the least common and has been described only in a small number of cases. CASE-DIAGNOSIS/TREATMENT Four patients were admitted to(More)
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(More)
BACKGROUND In infants, vitamin B12 deficiency may be due to an inborn error of absorption and metabolism, or nutritional problems. CASE PRESENTATION An exclusively breastfed 5-month-old Italian male infant, who was born after a normal full-term pregnancy to a vegan mother who was apparently daily treated with a multivitamin oral preparation during the(More)
The combination of captopril and indomethacin has been shown to control nephrotic proteinuria in an infant with congenital nephrotic syndrome of the Finnish type. We report the satisfactory control of congenital nephrotic syndrome by enalapril, maintaining normal serum albumin levels without albumin infusions. The haplotype data of our patient were(More)
The peritoneal equilibration test (PET) is routinely performed in adults treated with chronic peritoneal dialysis to assess the peritoneal transport rate and to optimize treatment prescription. Only a few and not well-standardized studies on the PET have been reported in children. Twenty-six PET's were performed in 16 children, mean age 10.9 +/- 4.9 years,(More)
Obstructive uropathy causes tubular resistance to aldosterone and severe metabolic imbalance may be precipitated by an episode of pyelonephritis. In the last 3 years we investigated 52 episodes of pyelonephritis (positive urine culture, elevated C reactive protein, fever, elevated neutrophil count) in 50 children between 15 days and 15 months of age.(More)
Bullous skin diseases are characterized by genetic abnormalities related to structural epidermal proteins or organ-specific autoantibodies against the same proteins and are revealed by blister formation on skin or mucous membranes, with differences in blister depth, morphology, and topography. Both inherited and autoimmune forms of these disorders can be(More)
BACKGROUND Esophageal and pharyngeal problems are common in the majority of patients with epidermolysis bullosa (EB). Repeated blister formation and ulceration, coupled with chronic inflammation, result in scarring and development of esophageal strictures. OBJECTIVE This study aimed to evaluate whether oral viscous budesonide (OVB) was useful for treating(More)
Ten fetuses with hydronephrosis underwent one to seven urine sampling procedures at 23 to 36 weeks' gestation to evaluate renal function. Postnatally, the infants' renal function was assessed by a combination of serum creatinine measurement, ultrasonography and renal scintigraphy. Six infants had pyelo-ureteric junction obstruction, two had megabladder with(More)
There are between 5,000 and 8,000 distinct rare diseases (RDs) affecting 6-8% of the population, most of which are caused by genetic defects. Many are highly complex, childhood-onset, multi-system disorders that are often associated with developmental disability, and require lifelong, highly specialized care and support. As larger numbers of children with(More)
