Bidi use among urban youth--Massachusetts, March-April 1999.

Tobacco use is the leading preventable cause of death in the United States. Bidis are small, brown, hand-rolled cigarettes primarily made in India and other southeast Asian countries consisting of tobacco wrapped in a tendu or temburni leaf (Diospyros melanoxylon ). In the United States, bidis are purchased for $1.50-$4.00 for one package of 20 and are available in different flavors (e.g., cherry, chocolate, and mango). Anecdotal reports indicate that bidi use was first observed during the mid-1990s and seems to be widespread among youth and racial/ethnic minority adolescents. This report summarizes preliminary data collected from a convenience sample of adolescents surveyed during March and early April 1999 in Massachusetts on the prevalence of bidi use among urban youth; these data indicate that of 642 youth surveyed, 40% had smoked bidis at least once during their lifetimes and 16% were current bidi smokers.

Self-reported feeding advice by physicians for common childhood illnesses.

BACKGROUND: A nutritious diet is important for recovery during illnesses. Dietary advice by physicians and consumption of food by the patients are often based upon their hot and cold concepts and beliefs about various foods rather than on scientific basis. OBJECTIVES: To look at the food-advising behaviour of physicians during illnesses and to know the maternal concepts about various foods being hot or cold. METHODS: A questionnaire was served to the physicians participating in a continuous medical education session held at the Aga Khan University and Hospital, asking them to write the foods they advise or restrict during different illnesses such as fever, jaundice etc. Mothers of sick children suffering from diarrhea and other illnesses were also interviewed to know their concepts about various foods. RESULTS: Six (10%) out of sixty physicians believed in hot and cold concepts of the food. A variety of common foods were either restricted or strongly recommended by 10% to 50% of these physicians without any scientific basis, 23% physicians restricted fatty foods in jaundice, 17% physicians restricted in cough and cold. Although the interviewed mothers believed in hot-cold concepts of food but 55-63% of them were not sure what is meant by hot or cold food. In spite of that 70-80% of these mothers classified chicken, meat, egg, brinjal, masoor and mangoes are hot foods and rice, yogurt, moong, banana and orange as cold foods. CONCLUSION: Hot-Cold concept of food exists not only in mothers but also in physicians. Proper education regarding food intake is mandatory for both mothers and physicians to ascertain adequate intake of calories during sickness.

Allergy to Anacardiaceae: description of cashew and pistachio nut allergens.

Some members of the Anacardiaceae family, such as cashew nut, pistachio nut and mango, have been reported to cause immediate allergic reactions. We report three cases of anaphylaxis to cashew nuts. With the aim of describing the allergens existing in cashew and pistachio nuts, patients were prick tested with cashew and pistachio extracts. Specific IgE against both nuts was studied by CAP and SDS-PAGE/immunoblotting. It was found that skin tests and specific IgE to cashew and pistachio nuts were positive in the three patients. Both nuts showed several protein bands in SDS-PAGE. The strongest IgE-binding bands had similar molecular weights (15, 30 and 60 kDa) in cashew and pistachio nuts. These main bands were found to be sensitive to reducing agents. It was concluded that these three patients suffered immediate reactions to cashew nut due to an IgE-mediated mechanism.

Enrichment of the diet with synthetic and natural sources of provitamin A.

The use of available food rich in provitamin A and retinol as well as fortification of local food are known to result in adequate vitamin A status. In Brazil, several regional foods are known to be good sources of provitamin A such as buriti, several palm oils, mango and others. Improving the consumption of these locally available natural sources of provitamin and vitamin A would cover the needs of the vulnerable population. At the same time fortification of industrialized foods with natural and/or synthetic forms of provitamin A could speed up and fill the gap between requirement and low intake of this vitamin in many parts of the country. This approach has been considered by many as the most effective intervention program to prevent micronutrient deficiencies in developing countries. Our previous studies on the subject have shown that cooking vegetable oil, mainly soybean oil, is a very good alternative vehicle to be fortified and supply vitamin A to the population. Lately we have also enriched the same soybean oil with beta-carotene. Addition of this provitamin A to the oil showed it to be stable when heated at cooking and frying temperatures (retention of 92.4 +/- 6.7% and 65.4 +/- 8.6%, respectively). When rat or human food was prepared with carotene-enriched cooking oil, its bioavailability in experimental animals and absorption in humans were shown to be adequate. An alternative for Brazil, besides adding chemical forms of the vitamin to the cooking oil, would be to mix available carotene-rich palm oil to the soybean oil. There are already regional uses of carotenoid-rich palm oils in the preparation of local dishes in some parts of Brazil and this would facilitate its acceptance by the population. Enrichment of common foods in Brazil, such as soybean oil, with chemical forms of beta-carotene or mixing rich sources of provitamin A can be a good alternative to improve the intake of vitamin A by the Brazilian population.

Latin American food sources of carotenoids.

Latin America has a wide variety of carotenogenic foods, notable for the diversity and high levels of carotenoids. A part of this natural wealth has been analyzed. Carrot, red palm oil and some cultivars of squash and pumpkin are sources of both beta-carotene and alpha-carotene. beta-carotene is the principal carotenoid of the palm fruits burití, tucumã and bocaiuva, other fruits such as loquat, marolo and West Indian cherry, and sweet potato. Buriti also has high amounts of alpha-carotene and gamma-carotene. beta-Cryptoxanthin is the major carotenoid in caja, nectarine, orange-fleshed papaya, orange, peach, tangerine and the tree tomato. Lycopene predominates in tomato, red-fleshed papaya, guava, pitanga and watermelon. Pitanga also has substantial amounts of beta-cryptoxanthin, gamma-carotene and rubixanthin. Zeaxanthin, principal carotenoid of corn, is also predominant only in piquí. delta-Carotene is the main carotenoid of the peach palm and zeta-carotene of passion fruit. Lutein and beta-carotene, in high concentrations, are encountered in the numerous leafy vegetables of the region, as well as in other green vegetables and in some varieties of squash and pumpkin. Violaxanthin is the principal carotenoid of mango and mamey and is also found in appreciable amounts in green vegetables. Quantitative, in some cases also qualitative, differences exist among cultivars of the same food. Generally, carotenoids are in greater concentrations in the peel than in the pulp, increase considerably during ripening and are in higher levels in foods produced in hot places. Other Latin America indigenous carotenogenic foods must be investigated before they are supplanted by introduced crops, which are often poorer sources of carotenoids.

[Ocular manifestations associated with vitamin A deficiency in a rural area of Burkina Faso].

Vitamin A deficiency can cause nyctalopia, hemeralopia, xerophthalmia, and even blindness. Studies have demonstrated the extent of this problem in various regions of Burkina Faso but extrapolation of these findings to other countries is difficult because of methodological problems. In the initial phase of study, signs of hemeralopia were noted in 14 of 466 children between the ages of 6 and 14, indicating an incidence of 3 p. 100 in this age group. In the second phase, examination of 281 subjects of all ages from 30 randomly selected families in the same village indicated that the incidence of hemeralopia was 3.9 p. 100 (6 p. 100 in children between 2 and 5 years old). Clinical examination demonstrated evidence of xerophthalmia in 7 p. 100 of subjects. The incidence fell to 50 p. 100 after the mango season and to 0 p. 100 after administration of 200,000 IU of vitamin A. Of the 8 cases of blindness observed in this study, 5 were due to onchocerciasis and 2 to vitamin A deficiency. These findings document the role of vitamin A deficiency in the occurrence of severe ocular manifestations in Burkina Faso and underline the need for preventive action.

[Asthma risk factors].

OBJECTIVE: To study the magnitude of risk factors known for asthma in 6-10 year-old children. MATERIAL AND METHODS: This is a case- and control-study with 6-10 year-old children; 58 were asthmatic and 117 were control, with a relation 2:1. Asthmatic patients were recruited from consult of immuno-allergies department and control patients, from familial medicine consult of Hospital de Especialidades 71, IMSS. Indirect (mother) and directed surveys were applied, they were of multiple option for exploring the most known in literature-risk factors. Statistical management was performed by odds ratio with confidence interval of 95%. RESULTS: The following variables were considered risk factors: ingestion of artificial colorants before having 1 year old (OR = 13.2), living in an urban area (OR = 7.74), maternal smoking during pregnancy (OR = 2.4), wool contact before having 1 year old (OR = 2.11), passive smoking exposure during pregnancy (OR = 1.486) and feeding with industrialized milk (OR = 1.2). CONCLUSIONS: Environmental risk factors are very important in our population, as well as early ablactation; however, ingestion before having 1 year old of allergens as egg, chocolate, orange and mango was not considered risk factor.

Imported furuncular myiasis in Germany.

Furuncular myiasis is a parasitic infestation of human and other vertebrate tissues by fly larvae of primarily two species: Dermatobia hominis (human botfly, t6rsalo, or berne) in Mexico and South and Central America and Cordylobia anthropophaga (tumbu fly or mango fly) in Africa. Cuterebra species (rabbit and rodent botflies) are also rarely reported to cause furuncular myiasis only within the United States. Although these species inhabit different geographic regions and have different life cycles, their clinical presentations can be similar. We describe a case of "imported" human botfly (D. hominis) furuncular myiasis in a U.S. Army soldier stationed in Germany. We review the life cycles of human botflies and key aspects of their clinical presentation, differential diagnosis, and various therapeutic modalities. Most physicians may never encounter myiasis and attribute a patient's complaints to an insect bite or skin infection that will heal without treatment. However, the diagnosis of furuncular myiasis should be considered by remembering the basic elements of this condition: recent travel history to the tropics and a sterile, persistent furuncle with sensations of movement and pain.

Bionomics of Culex epidesmus associated with Japanese encephalitis virus in India.

Various biological characteristics, including seasonal abundance, diurnal resting habits, feeding behavior, larval habitats, and oviposition, of Culex epidesmus were studied in Gorakhpur District, Uttar Pradesh, India, from 1990 to 1999. Prevalence of adults was recorded between June and October, with a peak in August. The bushy undergrowth of mango and teakwood plantations served as diurnal resting habitat. Blood-meal analysis of wild-caught females showed that the most of them had fed on bovines. Temporary pools of rainwater and paddy fields containing freshwater and filamentous green algae were found to be suitable larval habitats. Gravid females laid eggs and immature stages grew well in the presence of green algae. Freshly laid egg rafts were found to be boat shaped and individual eggs were a white-cream color. The number of eggs per raft deposited by individual Cx. epidesmus varied from 118 to 288, with an average of 199 eggs per specimen.

Estimated intake and food sources of vitamin A, folate, vitamin C, vitamin E, calcium, iron, and zinc for Guamanian children aged 9 to 12.

This study describes the nutrient intake and food sources of select vitamins and minerals for children on Guam. Food records (n = 954) from public school students aged nine to twelve of all regions on Guam were analyzed for nutrient content and compared to Recommended Dietary Allowances (RDA). Individual foods were condensed into 194 food aggregates and food lists representing 84% to 91% of the major vitamins and minerals in the diet of the children were developed by frequency analysis. Median intake of calcium, vitamin E, folate were less than 50% of the Recommended Dietary Allowance (RDA) and mean intake of these nutrients was 60% RDA or less. Mean and median vitamin A intake was 107% and 76% RDA, respectively. Both mean and median intake of Vitamin C, iron and zinc were present at levels above 100% RDA. Rice, meat, fruit drink from powder, milk, and fortified cereals are foods that provide substantial contributions to the vitamin and mineral content of the diets. Traditional, nutrient dense foods, such as fish, yams, papaya, and mango had minor contributions because of low frequently of consumption. Information from this study can be used to develop specific diet assessment instruments and culturally appropriate nutrition education.

Human urine and chicken feces as fruit fly (Diptera: Tephritidae) attractants for resource-poor fruit growers.

We evaluated human urine and chicken feces, two naturally occurring, inexpensive, and readily available substances, as baits for the capture of Anostrepha spp. (Diptera: Tephritidae) by using glass McPhail traps. Two studies were performed simultaneously in a commercial mango orchard in Veracruz, México. In the first study, we compared a 50% water dilution of human urine against hydrolyzed protein, both compounds at the fresh and 5-d-old stages, and water alone (control treatment). In the second study, we tested fresh chicken feces mixed with water, a torula yeast/borax solution at three different ages (1-4, 5-9, and 10-15 d), and water (control treatment). Both human urine and chicken feces were attractive to Anastrepha adults compared with water alone, but attracted two and three times fewer adults than hydrolyzed protein and torula yeast/borax, respectively. However, unlike torula yeast/borax, aging of human urine did not decrease its attractiveness. Five-day old human urine attracted numerically more A. serpentina females than males, similar numbers of A. obliqua males and females, and significantly more sexually immature A. obliqua females than mature ones. Chicken feces proved to be as attractive as the aged torula yeast/borax treatments for A. obliqua and A. serpentina. We argue that because both human urine and chicken feces are cost-free and can be easily obtained, they are viable, low-technology alternatives to costly commercial attractants, particularly for low-income growers or backyard farmers in Mexico and other Latin American countries.

[Influence of teas with fruit aroma and ice teas on pH and buffer capacity of saliva].

A number of teas with fruit aroma and ice teas has been tested on erosivity. The teas with a fruit taste have at their drinking temperature (45 degrees C) a pH between 6.2 to 7.4. Even teas with a citron or citrus flavour are neutral. The most acidic tea tested has a mango-peach-taste, but contains no buffer system. After mixing 1 ml of total saliva up to 10 ml tea or by rinsing the oral cavity with tea the pH of oral fluid was hardly lowered (minimum 6.3). In contrast, ice teas are rather acidic (pH < 4) and have a strong buffer capacity. Rinsing the oral cavity with 5 ml ice tea resulted in a decrease of the pH of the oral fluid to 4.1-4.9. However, within 2 minutes the pH in the oral fluid was already increased to 5.9-7.1 and after 5 minutes to 6.3-7.1. In other words, the teas with fruit aroma, based on organic taste components do not have an erosive potential. On the other hand, ice teas decrease the pH of the oral fluid drastically to a level that they become erosive. Therefore, from a dental point of view, teas with only a taste of fruit can be advised to replace drinking of soft drinks, but ice teas not.

Determination of fluquinconazole, pyrimethanil, and clofentezine residues in fruits by liquid chromatography with ultraviolet detection.

A simple method was developed for the determination of fluquinconazole, pyrimethanil, and clofentezine in whole fruit; peel; and pulp of mango, apple, and papaya. These compounds were extracted from fruit samples with a mixture of ethyl acetate-n-hexane (1 + 1, v/v). An aliquot (2 mL) of the extract was evaporated to near dryness under a stream of nitrogen, and the residue was dissolved with 2 mL methanol. The analysis was performed by means of liquid chromatography with ultraviolet detection at 254 nm using a gradient solvent system. The method was validated with fortified fruit samples at concentration levels of 0.05, 0.10, 0.20, and 0.50 mg/kg. Average recoveries (4-8 replicates) ranged from 80 to 95% with relative standard deviations between 3.5 and 12.7%. Detection limits ranged from 0.03 to 0.05 mg/kg for fruit pulp and 0.03 mg/kg for whole fruit. The quantitation limits ranged from 0.05 to 0.10 mg/kg for fruit pulp and 0.05 mg/kg for whole fruit. The analytical method was applied to fruit samples obtained from local markets.

Occurrence and significance of Cryptococcus neoformans in vegetables and fruits.

Cryptococcus neoformans was isolated from three of 437 (0.6%) samples of a wide variety of vegetables collected from a number of markets in Delhi. The vegetables yielding C. neoformans were tomato, Lycopersicon esculentum (1/70), 'vegetable sponge', Luffa cylindrica (1/56) and brinjal, Solanum melongena (1/55). Only solitary samples of these three vegetables were found to be positive. In vitro studies at 25 degrees C revealed that a reference C. neoformans isolate readily colonized, as did Candida albicans and Candida viswanathii (controls), sterilized slices of almost all the test vegetables and fruits (cut or uncut surface) which included tomato, 'vegetable sponge', brinjal, potato, carrot, radish, apple, guava, pineapple, pear, papaya, banana and mango. Sterilized juices of the same vegetables and fruits also supported adequate growth of the reference C. neoformans isolate as well as of C. albicans and C. viswanathii. However, the growth of C. neoformans on the afore-mentioned vegetables and fruits was rapidly masked by miscellaneous molds and bacteria if the test samples had not been sterilized prior to inoculation. Cryptococcus neoformans was not found in any of the 275 fruit samples investigated from the same markets. The results indicate that vegetables and fruits are unsuitable as natural habitats for C. neoformans although it may be sporadically isolated from these sources.

Phytate and fiber content in Thai fruits commonly consumed by diabetic patients.

The amount of phytate and total dietary fiber of 6 popular tropical fruits eaten by diabetic patient residing in Bangkok were studied. They were dragon fruit, durian, guava, longan, mango, and pineapple. Fruit containing the highest content of total dietary fiber was guava which had about 2.7%. Longan contained the lowest fiber content equal to 0.19%. The highest content of phytate was found in pineapple about 0.09% and the lowest content was in longan about 0.037%. It was noticed that longan contained the lowest total dietary fiber and the lowest phytate content.

[Newcastle disease in southern Chad: peak epidemic periods and the impact of vaccination].

In spite of its universally acknowledged importance, backyard chicken production is still being hampered by Newcastle disease in some parts of the world. In Chad, the disease has been reported almost everywhere in the country and confirmed in several regions, but there are no control measures in place. A survey was conducted at three sites in south-eastern Chad in July and August 2001, based on face-to-face interviews with 20% of the peasant farmers keeping chickens at these sites. The aim was to collect information on peak epidemic periods and on ways in which the infection spreads. The survey revealed that the peak epidemic periods for Newcastle disease are April, during the mango harvesting and selling period, and December, when trade increases for the seasonal festivities. The survey also showed that peasant farmers attach great importance to chicken farming. The survey was followed by a vaccination trial in November 2001 and February 2002, using the La Sota strain administered ocularly. All of the birds vaccinated during the trial were successfully protected from the disease and both chicken production and the income of the villagers increased. The authors conclude that in order to sustain poultry farming and maximise production in the southern zone, vaccination programmes must be urgently introduced, campaigns to raise awareness of Newcastle disease should be carried out and financial support to pay for vaccines should be provided. Efforts to combat other causes of poultry mortality must also be undertaken.

Dietary intake of vitamin A in African pre-school children in Umlazi, South Africa.

Vitamin A deficiency has been shown to have an impact on morbidity and mortality and therefore prevalence rates are important for public health policy. We report the use of a 7-day recall, dietary questionnaire, which was validated and administered to 203 randomly selected urban African pre-school children in Umlazi, South Africa. Common vitamin A containing foods eaten were leafy green vegetables, pumpkin, sweet potato, mangoes and chicken liver. Although the mean daily intake of vitamin A was adequate, 19 children had intakes below the recommended dietary allowance (RDA). Thirteen of these children had eaten liver in the previous week, and as such were probably not at risk. It is therefore estimated that only 6 of the children (3%) were at risk for developing vitamin A deficiency.

[Appraisal of snakebite incidence in Senegal, West Africa].

Surveys were carried out in four savannah areas of Senegal. The studied zones had different climatic, economic and demographic characteristics. Two types of studies were performed: on the one hand, a retrospective survey carried out in health centres and, on the other, household surveys in the corresponding areas; all households were questioned in Niakhar, but only selected households in other areas following WHO method of cluster survey for vaccine coverage. Questions involved the circumstances of the bite, symptoms and treatment. The retrospective survey reported very few cases of snakebites over the prospected period. In addition, two zones of surveys were population study areas under observation since more than 20 years and, it has been possible to check certain information in the data base. In the first zone, Thies, a sub-urban area (population density higher than 150 inhabitants per km2), primarily occupied by fruit plantations (mangos, oranges, lemons) and gardens, the annual incidence of snakebites (i.e. all snakebites including those without any symptoms) reached 43 bites per 100,000 and mortality was 1.8 deaths per 100,000. In the study zone of Niakhar, located in the groundnut culture area of Senegal which is also highly populated (130 inhabitants per km2), the incidence of snakebites was 23 bites per 100,000 and mortality was close to 1.8 deaths per 100,000 a year. The area of Nioro du Rip is a mixed agricultural area (food producing and revenue agriculture) and less populated (100 inhabitants per km2). The annual incidence was roughly of 304 per 100,000 and the mortality 3.6 per 100,000. Finally, the fourth area, Bandafassi in the extreme South-East of Senegal is a mountainous zone exclusively occupied by bush and food producing agriculture, and sparsely populated (20 inhabitants per km2). The incidence was 915 per 100,000 and the mortality 11 deaths per 100,000. The population at risk involved males from 15 to 45 years. Pastoral work (agriculture and breeding) was at the origin of the majority of the accidents. The recourse to traditional practitioners was systematic, which explained why the data from the health centers were not relevant enough to evaluate the importance of the envenoming.
