Actual incidence of severe neonatal hypoglycemia in non-risk term neonates: A 10 year survey of all cases in Toyama Prefecture, Japan.

Background: Severe neonatal hypoglycemia may cause irreversible neurological sequelae. Although blood glucose (BG) screening in term neonates without risk factors for hypoglycemia (non-risk neonates) is not recommended in the current guidelines, severe hypoglycemia can occur in such neonates. To evaluate the necessity of BG screening in non-risk neonates, it is important to determine the accurate incidence of severe hypoglycemia in those neonates.

Exclusive breast-feeding and postnatal changes in blood sodium, ketone, and glucose levels.

Background: Blood sodium and ketone are parameters of dehydration and fasting, respectively. Little is known, however, about the postnatal changes in these parameters in healthy, term, exclusively breast-fed neonates.

Methods: Capillary blood sodium, β-hydroxybutyrate (β-OHB), and glucose levels in 628 samples obtained from 392 healthy, term, exclusively breast-fed neonates during the first 12-143 h of life were examined.

Capillary Blood Ketone Levels as an Indicator of Inadequate Breast Milk Intake in the Early Neonatal Period.

Objective: To determine the utility of capillary blood ketone levels as an indicator of inadequate intake of breast milk in the early postnatal period.

Study Design: Levels of capillary blood beta-hydroxybutyrate (βOHB), the main ketone body in the blood, were measured with a bedside ketone meter in 585 full-term neonates aged 48-95 hours who were breastfed exclusively. Relationships between weight-loss percentage, blood sodium, glucose, pH, partial pressure of carbon dioxide, base-deficit levels, and βOHB levels were investigated.

Virus myocarditis in a 1-month-old boy presenting as two types of paroxysmal supraventricular tachycardia.

Herein we describe the case of a 1-month-old boy with acute viral myocarditis, who presented with two kinds of paroxysmal supraventricular tachycardia, and who was cured after medical treatment. He was brought to the emergency room with poor feeding due to fever. On the third day of hospitalization, a narrow QRS tachycardia (180-200 beats/min) was detected.
