Comparison of behavior modification with and without swaddling as interventions for excessive crying.

OBJECTIVE: To test the hypothesis that swaddling is an effective method to reduce crying, we compared a standardized approach of regularity and stimulus reduction with the same approach supplemented with swaddling. STUDY DESIGN: Healthcare nurses coached 398 excessively crying infants up to 12 weeks of age for 3 months. Outcome measurements were crying as measured by Barr's 24-hour diary and parental perception of crying. RESULTS: Crying decreased by 42% in both groups after the first intervention week. Swaddling had no added benefit in the total group. Young infants (1-7 weeks of age at randomization) benefited significantly more from swaddling as shown by a larger decrease of crying over the total intervention period. Older infants (8-13 weeks of age at randomization) showed a significantly greater decrease in crying when offered the standardized approach without swaddling. The actual difference in crying time was 10 minutes. CONCLUSION: For older babies, swaddling did not bring any benefit when added to regularity and stimuli reduction in baby care, although swaddling was a beneficial supplementation in excessively crying infants <8 weeks of age.

NSAIDS inhibit the IL-1 beta-induced IL-6 release from human post-mortem astrocytes: the involvement of prostaglandin E2.

Epidemiological studies have shown that steroidal as well as non-steroidal anti-inflammatory drugs lower the risk of developing Alzheimer's Disease (AD). A suppressive effect of these anti-inflammatory drugs on local inflammatory events in AD brains has been suggested, however the mechanisms responsible are still unknown. In this study we investigated at cellular level the influence of two anti-inflammatory drugs-dexamethasone and indomethacin--and an experimental specific cyclooxygenase-2 inhibitor, BF389, on the production of the pro-inflammatory cytokine IL-6 and the inflammatory mediator PGE2 by human astrocytes. Two human post-mortem astrocyte cultures (A157 and A295) and astroglioma cell lines (U251 and U373 MG) were found to secrete considerable amounts of IL-6 upon stimulation with IL-1beta. The glucocorticoid dexamethasone inhibited the IL-1beta-activated release of IL-6 from the postmortem astrocyte cultures A157 and A295 and from the astroglioma cell lines. The non-specific cyclooxygenase inhibitor indomethacin and BF389 only suppressed the IL-6 release by post-mortem astrocyte culture A157. This post-mortem astrocyte culture was found to produce large amounts of PGE2 upon stimulation with IL-1beta, whereas in the supernatants of the postmortem astrocyte culture A295 and the astroglioma cell lines, low PGE2 concentrations were detected. Addition of exogenous PGE2 prevented the inhibitory effect of indomethacin and BF389 on the IL-1beta-activated IL-6 release from A157 astrocytes and largely potentiated the IL-1-induced release of IL-6 from all astrocytes/astroglioma cells tested. Dexamethasone also inhibited the PGE2 release from the astrocytes and astroglioma cells, however the inhibitory effect of dexamethasone on the IL-1beta-activated IL-6 release could not be prevented by the addition of PGE2. The observed reduction of IL-6 and/or PGE2 from astrocytes may be involved in the mechanism underlying the beneficial effects of these drugs in AD.
