| a survey of intestinal parasitism in a community on the pan american highway route in eastern panama. | a survey of intestinal parasitism was conducted at yaviza, a town in eastern panama's province of darien. single stool specimens from 202 persons, representing 11 percent of the town's total population, were examined. in all, 181 (90 per cent) of the specimens examined were found positive for one or more potentially pathogenic parasites. the most common parasite found was trichuris trichiura, which was observed in 80 per cent of the samples. others were ascaris lumbricoides, in 62 per cent of th ... | 1975 | 167889 |
| soil-transmitted helminth infections in school children from cocle province, republic of panama. | a survey was carried out to determine values for the prevalence and intensity of infection of intestinal helminths in children living in cocle province, republic of panama. the data set consisted of the results of microscopic examinations (modified kato katz technique) of stool samples collected in november 1987 from 661 children attending primary schools in 4 communities in the province. the overall prevalences of ascaris lumbricoides, hookworm and trichuris trichiura infections were found to b ... | 1989 | 2594420 |
| intestinal helminthiases in relation to the socioeconomic environment of panamanian children. | a cross-sectional investigation was made into ascariasis and nutritional status in panamanian preschool children from october 1983 to july 1984. within this framework, an analysis was undertaken of possible relationships between a range of intestinal helminthiases and the socioeconomic status of the participants. attention was paid to caregiver's education, parental occupation, family earnings, quality of housing and sanitation in the assessment of socioeconomic status. on this basis, strong ass ... | 1988 | 3347848 |
| contributions of ascariasis to poor nutritional status in children from chiriqui province, republic of panama. | relationships between ascariasis and lactose digestion and between ascariasis and food transit time from mouth to caecum were investigated in young children from chiriqui province, republic of panama. the breath hydrogen method was used in both studies. ascaris-infected children showed a significantly poorer degree of lactose digestion following a test oral load than uninfected children. recovery of the capacity of the children to digest lactose was still not fully complete for at least 3 weeks ... | 1987 | 3696781 |
| ascaris lumbricoides infection in pre-school children from chiriqui province, panama. | an epidemiological survey of intestinal parasitic infections was conducted in a sample of 203 children aged 3-5 years from a semi-urban and a rural community in chiriqui, panama, in 1983-4. on the basis of stool examinations, the prevalences of ascaris lumbricoides, trichuris trichiura, hookworm, giardia intestinalis, entamoeba spp. and strongyloides stercoralis were found to be 27, 34, 14, 15, 5 and 4% respectively. the results from children from the two communities were compared. polyparasitis ... | 1987 | 3696782 |
| benefit of vitamin a supplementation on ascaris reinfection is less evident in stunted children. | despite the common coexistence of vitamin a deficiency and ascaris infection in preschool children in developing countries, and despite the widespread use of vitamin a supplements, remarkably little is understood about the impact of vitamin a supplementation on this gastrointestinal nematode. the ministry of health of panama recently initiated a vitamin a supplementation program in rural indigenous populations. we took advantage of this initiative to assess the benefit of 200,000 iu (60 mg retin ... | 2007 | 17513406 |
| assays to detect beta-tubulin codon 200 polymorphism in trichuris trichiura and ascaris lumbricoides. | the soil-transmitted helminths (sth) ascaris lumbricoides and trichuris trichiura are gastrointestinal parasites causing many disabilities to humans, particularly children. the benzimidazole (bz) drugs, albendazole (alb) and mebendazole (mbz), are commonly used for mass treatment for sth. unfortunately, there is concern that increased use of anthelmintics could select for resistant populations of these human parasites. in veterinary parasites, and lately in filarial nematodes, a single amino aci ... | 2009 | 19308251 |
| diarrhea and novel dietary factors emerge as predictors of serum vitamin b12 in panamanian children. | the role of gastrointestinal infection as a factor determining vitamin b12 status in populations with low intake of animal-source foods is unclear. | 2011 | 21560464 |
