pediatric hypermagnesemia

Won Kyoung Jhang, Yoon Jung Lee, Young A Kim, Seong Jong Park, Young Seo Park
In this report, we present a pediatric case of severe symptomatic hypermagnesemia resulting from the use of magnesium oxide as a laxative in a child undergoing continuous cyclic peritoneal dialysis for end-stage renal disease. The patient showed abnormal electrocardiography (ECG) findings, such as tall T waves, a widened QRS complex, and irregular conduction, which were initially misdiagnosed as hyperkalemia; later, the correct diagnosis of hypermagnesemia was obtained. Emergent hemodialysis successfully returned the serum magnesium concentration to normal without complications...

Magnesium (Mg), an essential element, plays important roles in many physiological functions. Mg deficiency is associated with insulin resistance, cardiovascular disease, and disorders of the nervous system. The aim of this study was to determine reference values for serum Mg concentration in pediatrics. Serum Mg level was measured by flame atomic absorption spectrophotometry in 306 subjects (141 boys and 165 girls), aged 3-19 years, selected from among participants of the Tehran Lipid and Glucose Study. The International Federation of Clinical Chemistry guidelines (IFCC) and the robust method were used for determining reference values for sample sizes greater or less than 120 subjects respectively...

A high blood magnesium level is a rare but life-threatening event. This case report describes an accidental overdose of magnesium that occurred in an 18-month-old girl during a routine operation. The effects of high magnesium levels and its treatment are explained in detail.

We report a case of fatal hypermagnesemia resulting from the unsupervised use of high doses of magnesium oxide administered as part of a regimen of megavitamin and megamineral therapy to a child with mental retardation, spastic quadriplegia, and seizures. The treatment regimen was given at the recommendation of a dietician working as a private nutritional consultant without the involvement or notification of the child's pediatrician. Hypermagnesemia is an uncommon but serious side effect of the use of magnesium containing compounds...

OBJECTIVE: Our aim was to analyze the incidence of metabolic disturbances in critically ill children and to evaluate their correlation with severity of illness, complications, mortality and length of hospital stay. PATIENTS AND METHODS: We retrospectively studied 360 children who were admitted into a Pediatric Intensive Care Unit (PICU) between January 1995 and May 1996. We analyzed age, sex, initial diagnosis, complications, length of hospital stay and initial and final concentrations of serum glucose, calcium, phosphorus, magnesium and alkaline phosphatase...

A unique chemical intoxication by Dead Sea water and its resultant physiological effects of combined severe hypercalcemia and hypermagnesemia are described. Of 48 adult patients, 16 had at least one severe clinical manifestation of either disturbed sensorium or a syndrome similar to adult respiratory distress syndrome. The patients had tachyarrhythmias (11 of 38, 29%), conduction disturbance (nine of 37, 24%), and a normal QTc interval in the presence of severe hypercalcemia. Combined respiratory and metabolic acidosis and concomitant extreme hypercalcemia and hypermagnesemia, reaching serum levels up to 28...

Ca and Mg are biologically important minerals that are involved in maintaining the stability of membranes, muscle contractions, and enzyme activity in nearly all cells. Derangements of Ca and Mg homeostasis can precipitate serious and life-threatening problems in the critically ill patients. We examined serum ionized Ca and Mg levels in pediatric patients consecutively admitted to a pediatric ICU. Abnormal Mg and ionized Ca levels on admission were found in 43.3% and 17% of the patients, respectively. Hypocalcemia and hyper-magnesemia were both associated with poor outcome as measured by either survival or length of ICU stay...
