To determine the influence of ventilation control and work practices on the health of workers potentially exposed to organophosphate and carbamate compounds, we examined a total of 989 employees from pesticide factories in Taiwan during 1986-1987. Each employee was examined by a physician, and a blood sample was drawn for plasma cholinesterase, complete blood count, and liver and renal function tests. Forty-one employees with medical conditions that might alter the plasma cholinesterase were excluded. Results showed that 43 of 515 production employees had decreased plasma cholinesterase as compared with four of 340 non-production employees. Production employees working under adequate ventilation control seemed to have a lower prevalence of decreased plasma cholinesterase than those under inadequate ventilation control, although the difference was not statistically significant (p = 0.242). There was a significant association between the level of housekeeping and work practices and the prevalence of decreased plasma cholinesterase (p = 0.022). We conclude that inadequate ventilation control and poor work practices may create a potential danger of pesticide poisoning among production employees in Taiwan and should be corrected immediately.

There are many reasons why it is important to conduct the cognitive assessment and arrive at a preliminary diagnosis within the primary care setting. In addition to starting the patient on anti-cholinesterase medications, the physician must discuss with the family (and often the patient) issues related to financial matters and self-care. Alzheimer's patients who live alone may be targets for financial and personal exploitation, and are at risk for self-neglect. Community support or provision might be needed to assist with medication compliance, provide nutritional services by shopping for prepared foods or through Meals on Wheels, housekeeping to maintain cleanliness, adult day services to provide social and recreational activities, live-in companions, and assistance with other instrumental activities of daily living. Sometimes more structured or institutional living is necessary. Generally, the primary care practice is not set up to coordinate these additional services, as well as to provide ongoing care. We will discuss potential solutions to providing ongoing care in next month's column.

Annotation of the recently determined genome sequence of the major dengue vector, Aedes aegypti, reveals an abundance of detoxification genes. Here, we report the presence of 235 members of the cytochrome P450, glutathione transferase and carboxy/cholinesterase families in Ae. aegypti. This gene count represents an increase of 58% and 36% compared with the fruitfly, Drosophila melanogaster, and the malaria mosquito, Anopheles gambiae, respectively. The expansion is not uniform within the gene families. Secure orthologs can be found across the insect species for enzymes that have presumed or proven biosynthetic or housekeeping roles. In contrast, subsets of these gene families that are associated with general xenobiotic detoxification, in particular the CYP6, CYP9 and alpha esterase families, have expanded in Ae. aegypti. In order to identify detoxification genes associated with resistance to insecticides we constructed an array containing unique oligonucleotide probes for these genes and compared their expression level in insecticide resistant and susceptible strains. Several candidate genes were identified with the majority belonging to two gene families, the CYP9 P450s and the Epsilon GSTs. This 'Ae. aegypti Detox Chip' will facilitate the implementation of insecticide resistance management strategies for arboviral control programmes.
