Transient renal tubulopathy: a case report.

A five-year-old boy was evaluated for fever, abdominal pain, vomiting, and diarrhea lasting two days. Chest radiograph revealed a left bronchopneumonia. Metabolic work-up demonstrated phosphaturia, glucosuria, calciuria, proteinuria, profound hypophosphatemia, hypouricemia, borderline hypomagnesemia, and normoglycemia.

N-acetylcysteine ameliorates amphotericin-induced nephropathy in rats.

Background: Amphotericin B may cause acute reduction in renal function. N-acetylcysteine (NAC) has a renoprotective activity in several nephrotoxic renal insults, but its effect on amphotericin-induced renal failure has not been investigated yet.

Methods: Acute renal failure was induced in 30 Sprague-Dawley rats by a single intraperitoneal injection of amphotericin B (50 mg/kg).

Erythrocyte Na+,K+-ATPase and nasal potential in pseudohypoaldosteronism.

Objectives: Pseudohypoaldosteronism type 1 (PHA1) is a rare inherited disorder characterized by salt-wasting due to target organ unresponsiveness to mineralocorticoids. PHA1 comprises two clinically and genetically distinct entities; isolated renal and systemic forms.

Design: The aim of this study was to investigate red blood cell (RBC) Na+,K+-ATPase activity and nasal potential difference (PD) in two pairs of unrelated dyzygous twins; one with the systemic form of the disease (PHA1-S) and the second with the isolated renal form (PHA1-R).
