Restoration of locus coeruleus noradrenergic transmission during sleep.

Sleep is indispensable for health and wellbeing, but its basic function remains elusive. The locus coeruleus (LC) powerfully promotes arousal by releasing noradrenaline. We found that noradrenaline transmission is reduced by prolonged wakefulness and restored during sleep.

Decreased cyclosporine exposure during the remission of nephrotic syndrome.

In this paper, we report the pharmacokinetics changes observed in seven children with steroid-resistant nephrotic syndrome (SRNS). They received cyclosporine A (CsA) microemulsion 6 mg/kg/day and, one week later, they were admitted to perform a 12-h pharmacokinetic profile with eight time sample points. The pharmacokinetic profile was repeated at 24 weeks of treatment, when all patients achieved remission.

[Pharmacologic clinical monitoring of serum vancomycin levels in pediatric patients].

Objective: To analyze the results from the clinical monitoring of serum vancomycin levels among pediatric patients receiving this drug.

Methods: Retrospective study of data from routine monitoring of serum vancomycin concentrations. The study population includes children who received vancomycin for more than 3 days and had peak and trough vancomycin serum concentration documented.
