nocturnal enuresis/カリウム

Background and objectives: There are controversial results in the literature regarding urinary electrolytes, especially potassium, in enuretic children. KCNJ10 channel protein, a member of the Kir 4.1 family is expressed in renal distal

Primary nocturnal enuresis (PNE) is the most common type of nocturnal enuresis in children, but its etiology remains unclear. Recent studies indicated the differences in urinary electrolytes in enuretic children, and stressed the existence of a renal tubular maturation defect. In this study, 30

OBJECTIVE We investigated the effect of imipramine on nocturnal urine output in patients with nocturnal enuresis. METHODS There were 15 monosymptomatic enuretic patients 15 to 37 years and 8 control subjects 25 to 32 years old. We measured nocturnal urine output, urine osmolality, creatinine

OBJECTIVE Desmopressin may be a useful treatment in some, but not all, patients with nocturnal enuresis. We have evaluated a relation between nocturnal urine output in patients with primary monosymptomatic nocturnal enuresis and the treatment response to synthetic vasopressin. METHODS Adolescent or

OBJECTIVE To compare excretion of ions and prostaglandins by the kidney in children with noctural enuresis. METHODS Thirty-two children with primary nocturnal enuresis and 23 normal children were examined. Osmolality and sodium and potassium concentrations were measured in their urine and blood

OBJECTIVE We evaluated the acute effect of indomethacin on renal water and solute handling in children with coexisting monosymptomatic nocturnal enuresis and desmopressin resistant nocturnal polyuria, and in healthy controls. METHODS A total of 23 subjects were recruited, consisting of 12 children

OBJECTIVE We verify the sodium fraction excretion rate (FE Na) and potassium fraction excretion (FE K) rates in monosymptomatic nocturnal enuresis. We also correlate FE Na and FE K to urinary osmolality, nocturnal polyuria and vasopressin in the same population. METHODS A total of 438 children 6 to

OBJECTIVE The aim of this study was to investigate the pathophysiologic cause(s) of primary nocturnal enuresis. Therefore, electrolyte concentrations of urine specimens were evaluated in the morning, and alterations compared between enuretics and nonenuretics. METHODS First morning urine specimens

OBJECTIVE Although nocturnal polyuria in patients with monosymptomatic enuresis can largely be explained by the decreased nocturnal vasopressin secretion hypothesis, other circadian rhythms in the kidney also seem to have a role. We recently documented an absent day/night rhythm in a subgroup of

OBJECTIVE To assess urinary nitrite excretion, a stable end product of nitric oxide (NO), in patients with enuresis and in normal controls, and to evaluate the effects of indomethacin (a potent prostaglandin synthesis inhibitor) on urinary nitrite excretion, other urinary variables and bladder

OBJECTIVE To report an atypical presentation of shock and acute adrenal insufficiency in an adolescent male. METHODS A 14-year-old boy with a history of nocturnal enuresis presented with a clinical picture suggestive of septic shock refractory to aggressive fluid and vasopressor management. History

OBJECTIVE In a subgroup of children with enuresis an increase in nighttime water and solute excretion has been documented. To investigate if modifications in renal function are involved in nocturnal enuresis, we assessed circadian variation in natriuresis and tubular sodium handling in polyuric

The circadian variation of plasma atrial natriuretic peptide (ANP) in relation to urinary excretion of sodium (UNa) and potassium (UK) as well as clearance of creatinine (Ccrea) was assessed in 15 juvenile patients with enuresis nocturna and compared with 11 age-, sex-, and weight-matched normal

OBJECTIVE We investigate the underlying pathophysiological cause of primary nocturnal enuresis by comparing electrolyte alterations in urine samples of enuretics during the daytime and nighttime compared with those of nonenuretic subjects. METHODS Urine output, urine specific gravity and urinary
