After the 1999 West Nile (WN) encephalitis outbreak in New York, 2,300 overwintering adult mosquitoes were tested for WN virus by cell culture and reverse transcriptase-polymerase chain reaction. WN viral RNA and live virus were found in pools of Culex mosquitoes. Persistence in overwintering Cx. pipiens may be important in the maintenance of WN virus in the northeastern United States.

Verbal debriefing after a traumatic incident may interrupt the natural adaptive processes that help people to deal with such incidents. This article examines the effectiveness of written interventions to help people experiencing distress after trauma experienced at work. As an alternative to critical incident debriefing, the authors recommend a staff education programme in tandem with written disclosure.

The screening of different ethnic groups who live in the same natural system have enabled the authors to study interaction between genetic and environmental factors as a part of etiology of diabetes mellitus. In New Caledonian country areas, the prevalences of glucose tolerance abnormality (GTA) and diabetes mellitus (DM) have been higher with people of polynesian descent than with Melanesians. GTA 7.6 p. ct. versus 5.1 p. ct. DM 6.5 p. ct. versus 2.2 p. ct. The prevalence of these combined diseases have been 14 p. ct. with the Polynesians and 7.2 p. ct. with Melanesians. These two ethnic groups have shown mean ages and obesity rates similar enough to lead the authors to deny these two factors a major part in the difference between the ethnic prevalences of DM. Besides, the mean plasmatic glycemia two hours after a dose of glucose and the relative risk of DM and GTA according to age and obesity rate have shown that the slight differences between these groups are not involved in the different prevalences of DM. This inter-ethnic difference may be due to genetic factors. However, some environment linked factors besides obesity (such as diet and daily life activity) may share a major part in this difference.
