Two sisters, eight and six years old, respectively, were admitted to Mackay Memorial Hospital in 1993 with the chief complaints of growth retardation, polyuria and nocturnal enuresis. Poor urinary concentration, sodium wasting, anemia and renal insufficiency were noted during hospitalization. Ultrasonography revealed increased renal echogenicity, loss of corticomedullary differentiation and multiple tiny corticomedullary cysts in both kidneys. Renal histopathology showed mild increase in glomerular mesangial cellularity and matrix, mild focal tubular atrophy with thickening of the tubular basement membrane. Other family members were screened by ultrasonography and found another six patients in two generations of the paternal side. Renal cysts were found in five cases. Three of them had progressively deteriorating renal failure. Five had stable renal function after three years of supportive treatment. Thus, it was concluded that the age of onset does not differentiate medullary cystic disease (MCD) from juvenile nephonophthisis (JN), and that JN and MCD could be considered a clinical complex. The absence of corticomedullary cysts on ultrasonography does not preclude the diagnosis. It is also suggested that any children with clinical symptoms of polyuria, polydipsia, anemia and growth retardation from their early years should be carefully examined, and the family history should be investigated to permit early detection of the disease.

Familiar hypomagnesemia with hypercalciuria and nephrocalcinosis is a rare syndrome belonging to the group of heterogeneous tubular diseases whose common characteristic is renal magnesium wasting. We present a 9 year old boy with polyuria, polydipsia and enuresis. Radiologic and ultrasonographic examinations showed nephrocalcinosis. Hypomagnesemia, normokaliemia, hypermagnesiuria, hypercalciuria, incomplete distal tubular acidosis, hypocitraturia and mild renal failure were found. Treatment with magnesium salts, hydrochlorothiazide, potassium citrate and sodium bicarbonate did not restore magnesium or calcium levels to normal. Renal function and nephrocalcinosis remain stable after 3 year's treatment. In conclusion, we report a new case of this rare syndrome caused by a congenital defect in magnesium reabsorption and discuss the evolution of the illness during 3 years' treatment.
