Infection characteristics and treatment of Staphylococcus aureus bacteraemia at a tertiary children's hospital.

Background: Staphylococcus aureus bacteraemia (SAB) causes considerable morbidity and mortality in children. Despite this, its epidemiology and risk factors are poorly understood, with minimal paediatric clinical trial data available to guide clinicians in management. We conducted a pilot study to characterise SAB and validate a severity classification for use in future clinical trials.

Progress in Understanding and Treating SCN2A-Mediated Disorders.

Advances in gene discovery for neurodevelopmental disorders have identified SCN2A dysfunction as a leading cause of infantile seizures, autism spectrum disorder, and intellectual disability. SCN2A encodes the neuronal sodium channel Na1.2.

Adjunctive therapies for Kawasaki disease.

Kawasaki disease (KD) is the most common cause of acquired heart disease in children in developed countries.(1,2) The primary goal of treatment is to prevent coronary artery aneurysms (CAA). Between 10 and 20% of KD patients are resistant to treatment with intravenous immunoglobulin (IVIG) and have an almost nine-fold increased risk of developing CAA.

Modeling of subcutaneous absorption kinetics of infusion solutions in the elderly using technetium.

Absorption kinetics of solutes given with the subcutaneous administration of fluids is ill-defined. The gamma emitter, technitium pertechnetate, enabled estimates of absorption rate to be estimated independently using two approaches. In the first approach, the counts remaining at the site were estimated by imaging above the subcutaneous administration site, whereas in the second approach, the plasma technetium concentration-time profiles were monitored up to 8 hr after technetium administration.

Subcutaneous fluid administration in elderly subjects: validation of an under-used technique.

In a crossover study in six volunteers over the age of 65, absorption of 500 mL of normal saline given subcutaneously was compared with that given intravenously. Tritiated water and technetium pertechnetate were used as water tracers. Tritium radioisotope levels in the blood increased in a smooth curve during subcutaneous infusion, reaching equilibrium levels within 60 minutes.
