Parents' and neonatal healthcare professionals' views on barriers and facilitators to parental presence in the neonatal unit: a qualitative study.

Background: Parent and infant separation in the neonatal unit is associated with adverse health outcomes. Family-integrated care has several advantages and the potential to reduce these adverse outcomes but requires parental presence. This study aimed to explore the views of parents and neonatal healthcare professionals (nHCPs) on barriers and facilitators to parental presence in a Swiss neonatal unit and to identify possible differences between nHCPs and parents, and between mothers and fathers.

Increased intracranial pressure caused by non-space-occupying arachnoid cysts: report of two patients.

In this article we report on two patients with arachnoid cysts previously treated by shunt implantation presenting with clinical signs of an increased intracranial pressure i. e., papilledema, headache and nausea.

Dopamine release in human neocortical slices: characterization of inhibitory autoreceptors and of nicotinic acetylcholine receptor-evoked release.

The autoinhibitory control of electrically evoked release of [3H]-dopamine and the properties of that induced by nicotinic receptor (nAChR) stimulation were studied in slices of the human neocortex. In both models [3H]-dopamine release was action potential-induced and exocytotic. The selective dopamine D2 receptor agonist (-)-quinpirole reduced electrically evoked release of [3H]-dopamine, yielding IC50 and I(max) values of 23 nM and 76%, respectively.

5-HT uptake blockade prevents the increasing effect of K(ATP) channel blockers on electrically evoked [3H]-5-HT release in rat and mouse neocortical slices.

To explore if prolonged--as opposed to acute--5-HT uptake blockade can lead to changes in the function of ATP-dependent potassium (K(ATP)) channels, we investigated in rat and mouse neocortical slices the effects of K(ATP) channel blockers on electrically evoked [3H]-serotonin ([3H]-5-HT) release after short- and long-term exposure to 5-HT uptake blockers. Glibenclamide (1 microM), a K(ATP) channel blocker, enhanced the electrically evoked [3H]-5-HT release by 66 and by 77%, respectively, in rat and in mouse neocortex slices. This effect was confirmed in the rat by tolbutamide (1 microM), another K(ATP) channel antagonist.
