Assessment of sanitation conditions by qualitative sanitation measurement.
Survey of sanitation conditions by qualitative sanitation measurement were carried out in three districts, Chachoengsao Province, Thailand. The sanitation of each household was assessed in terms of positive stool examination and scores of seven main sanitary activities which were used to classify each household's sanitation as hygienic or non-hygienic. ⋯ It was found that in the qualitative measurement of the household's sanitation as hygienic or non-hygienic, most sanitary activities were highly associated with the results of stool examination. From consideration of the sensitivity, specificity and kappa coefficient of significant sanitary activities as predictors and the result of stool examination was used as gold standard, it was apparent that a package of all main sanitary activities was the most appropriate measurement in the survey to assess sanitation conditions in the community.

Summarizing the general characteristics of food consumption pattern and dietary status of the country's central urban region, the following are brought to focus: Metro Manila as compared to all urban and rural areas consumes less cereal grains but more sugars and fats and oils; consumes more of the high quality protein foods such as meat, poultry, eggs, milk and dried beans; and consumes less of fruits and vegetables. Availability and affordability of foods in the respective sectors could have affected to a large extent the magnitude of consumption differences. Although urban households had the advantage of a more varied and quantitatively higher food consumption, their nutrient intake was not really very different from rural households. ⋯ There is therefore an "urban bias" of food supply to Metro Manila, that is, there is a much higher demand capacity for Metro Manila to draw food supply because of its higher income level and bigger population. The impact of this situation in terms of nutrition and food supply in the rural areas should be carefully examined so as not to put the rural areas in extreme disadvantage. FNRI nutrition surveys have shown that dietary energy inadequacy remains rampant in Metro Manila, while protein continues to be a marginal problem.(ABSTRACT TRUNCATED AT 400 WORDS)

Comparative StudyStudies on the control of hookworm and other soil-transmitted helminthiases in farmers in Zhejiang Province, China.
Different periodic selective chemotherapeutic schemes were used to control hookworm and other soil-transmitted helminthiases in eight villages in five counties in Zhejiang Province, China, 1985-1988. The results showed that the prevalence rates of hookworm, ascariasis, and trichuriasis decreased from 35.0-74.4%, 47.0-.76% and 22.9-47.5% to 3.2-15.8%, 9.9-47.8%, and 3.5-31.2%, respectively, using pyrantel pamoate (10 mg/kg for 1-2 days) or albendazole (400 mg for 1-2 days, once or twice a year for 2-3 years). ⋯ Moreover, the mean hemoglobin levels of sampled populations increased after several treatments. The authors recommend periodic selective chemotherapy as the main method to control soil-transmitted helminthiases, especially hookworm infections.

Yaws has been resurgent in the island of Tanna in southern Vanatu in the 1980's. Screening, conducted in 1988 and in 1989 during a mass treatment program identified a total of 464 clinical cases from the population of 20,200, a rate of 23 per thousand. Most of these (82%) were under 15 years of age. ⋯ A mass screening and treatment program was implemented in 1989 with 91.8% coverage. This program was designed to work in the context of primary health care and thus has enhanced the relationship between the health services and local villagers. The program was successfully integrated with other health activities including health education, treatment of other diseases and vector control.

Albendazole and infections with Trichuris trichiura and Giardia intestinalis.
One hundred and twenty-eight children aged 4 to 11 years old in Dhaka, Bangladesh were treated for infections with Trichuris trichiura and other intestinal parasites using a single dose of 400 mg of albendazole. Only one Trichuris infection was apparently cured although egg counts fell by about 50%. A larger single dosage is recommended to treat Trichuris. Eleven out of 46 infections with Giardia intestinalis were not detected after treatment (p less than 0.001).
