Chorioamnionitis and earlier gestational age are associated with neonatal hypercalcemia after maternal magnesium sulfate therapy: A case-control study.

Background: Magnesium sulfate (MgSO) is a tocolytic agent used to treat gestational hypertension and to prevent preterm labor. Neonatal hypocalcemia is a well-known side effect of maternal MgSO use. Cases of neonatal hypercalcemia after maternal MgSO have been reported.

Utility of fractional excretion of magnesium in diagnosing renal magnesium wasting in pediatric nephrology practice.

Background: Fractional excretion of magnesium (FE) is commonly used to diagnose of renal magnesium (Mg) wasting, but it can be affected by serum Mg (SMg) and serum creatinine concentration (SCr). We investigated the sensitivity and specificity of FE to diagnose Mg wasting in subgroups with different SMg and eGFR (estimated glomerular filtration rate) in pediatric nephrology practice.

Methods: One hundred and nineteen patients (59 males and 60 females, median 15 years) seen in our pediatric clinic were investigated for FE, SMg, eGFR, and urine Mg-to-creatinine ratio (Mg/Cr).

[Long-Term Survival with Distal Pancreatectomy and Postoperative Chemotherapy in a Patient of Pancreatic Invasive Ductal Adenocarcinoma of the Tail with Peritoneal Dissemination].

A 68-year-old man was referred to our hospital for detailed examination of the pancreatic tail tumor. The tumor was diagnosed as the pancreatic invasive ductal adenocarcinoma and the distal pancreatectomy was scheduled. During surgery, a 2 mm white nodule was observed on the posterior wall of the stomach.

A girl with membranous nephropathy associated with ventriculoperitoneal shunt infection.

Glomerulopathy associated with shunt infection is commonly membranoproliferative glomerulonephritis, whereas the causative organisms of secondary membranous nephropathy are usually viruses. We report a case of membranous nephropathy associated with shunt infection. The patient was born at 29-week gestation with a birth weight of 1178 g.

Transient hypercalcemia followed by hypocalcemia in a preterm infant after maternal magnesium sulfate therapy.

Maternal use of magnesium sulfate has been associated with neonatal hypocalcemia and bone changes. We report the case of a preterm male infant who presented hypercalcemia before developing hypocalcemia after maternal magnesium sulfate therapy. Magnesium sulfate was used for premature rupture of membranes for 32 days, and the patient was delivered at 33 weeks gestation.
