[Psychotropic drugs dispensed on the island of Bonaire].

Background: Up till now little is known about psychiatric disorders in relation to the use of psychotropics drugs on the Dutch Antilles, with the exception of Curaçao.

Aim: To map the quantity and type of psychotropics prescribed for Bonairians in 2009.

Method: We performed a retrospective data analysis of the antipsychotics dispensed by the pharmacies on Bonaire in 2009.

Rebreathing to cope with hyperventilation: experimental tests of the paper bag method.

To explore if and how the common rebreathing (paper bag) approach to hyperventilation works, two experiments were carried out. In the first experiment, 12 normal volunteers, aware of the common physiological rebreathing rationale, were twice asked to overbreath intensely and then either to rebreath or to restart normal ventilation. Alveolar CO2 increased more quickly and physical symptoms disappeared earlier in the rebreathing condition.
