Frecuencia de parasitosis en niños con diarrea

Abstract: Estudio transversal, descriptivo, comparativo, realizado entre febrero y abril de 2002, para determinar la frecuencia de parasitos en ninos menores de cinco anos con diarrea. Se compararon dos grupos: grupo estudio n=100 que ingresaron a la emergencia pediatrica, y un grupo control n=100 sin diarrea de la consulta externa del Hospital Universitario de Maracaibo. Se evaluo edad, sexo, estado nutricional, tipo de diarrea y parasitos. Se practico examen de heces al fresco con solucion salina, lugol y coloracion de Ziehl Neelsen. Se utilizo chi cuadrado, con indice de confiabilidad estadistica de 95% (p<0,05) y en ocasiones 99% (p < 0.01). La frecuencia de parasitosis en el grupo estudio fue 34% y 25% en el grupo control; sin diferencia en el sexo; en el grupo estudio los ninos de 13 - 24meses (35,3%) fueron los mas parasitados y en el grupo control de 25 - 60meses (52%). La desnutricion fue mas frecuente en el grupo estudio, siendo significativo (p<0,001). En el grupo estudio el tipo de diarrea mas frecuente fue la aguda (41,2%). Los protozoarios predominaron sobre los helmintos en ambos grupos: Giardia lamblia 38% y 44%; Cryptosporidium sp. 29% y 4%; Blastocystis hominis 21% y 12%; Entamoeba histolytica/E. dispar 6% y 12%. Los helmintos: Strongiloides stercolaris 18% y 8%, y Ascaris lumbricoides. 6% y 10%. De los parasitos solo Cryptosporidium sp. tiene una frecuencia significativa (p<0,01). Entre las asociaciones parasitarias, la mas frecuente fue Cryptosporidium sp y G. lamblia. Se concluye que en este grupo estudiado, la prevalencia de parasitosis fue elevada (34%), predominando los protozoarios sobre los helmintos.

Macronutrientes en leche de madres desnutridas

Abstract: SUMMARY. Macronutrients in milk of undernourished mothers. In a prospective, no experimental and comparative analysis, the relationship between the mother’s nutritional conditional and their macronutrient’s concentrations was evaluated in 40 samples from mothers who had children 15 days to 6 months old, in a hospital setting at the Emergency room of the Pediatric Ward of Maracaibo’s University Hospital in Maracaibo, Venezuela in one year period. Milk from two groups of 20 mothers each was analyzed: Group A (Experimental), mothers with undernourishment and Group B (Control), mothers with adequate nutritional status. Fat content was 3.8 ± 0.32 g/dl and 5.5 ± 1.08 g/dl respectively (p = 0.0001); proteins were 1.8 ± 0.21 g/dl and 2.4 ± 0.32 g/dl respectively (p = 0.0001), and carbohydrates were 6.06 ± 0.43 g/dl and 5.7 ± 0.45 g/dl respectively (p = 0.0136). In addition, caloric value was also different: 65.92 ± 15. 16.68 kcal/l and 83.25 ± 9.4 kcal/dl (p = 0.0002). The undernourished were in the range of group V Graffar Mendez-Castellano, confirming the relationship between undernutrition and poverty. It is concluded that the proteins, fat concentrations and the caloric value in the breast milk from undernourished mothers are of lower value than the nourished well mothers.

Determinación de las concentraciones de proteínas, hidratos de carbono y grasas en leche de madres en relactancia

Abstract: In a prospective, randomized and comparative trial the milk of 40 lactating mothers of hospitalized children at the Department of Pediatrics, University Hospital in Maracaibo, Venezuela was analyzed in a year period. They were divided in two groups of 20 mothers each: Group A, mothers in a relactation situation, and Group B (Control): Exclusive breastfeeding. Both types of milk were analyzed in a blind fashion to determine fat, proteins and carbohydrates. Results show that fat concentration (g/dL) was significantly more concentrated in Group B than in A, from 3.6 +/- 1.5 to 5.5 +/- 1.0 (p < 0.001), while in contrast, the carbohydrates concentration (g/dL) was decreased from 6.4 +/- 5.7 to 5.7 +/- 0.8 (p < 0.001). Moreover, proteins concentration (g/dL) was not significantly modified, since in group A it was 2.1 +/- 1.2 as compared to group B (2.4 +/- 0.3.) Caloric value was also significantly decreased from the control value of 83.2 +/- 9.4 to 66.7 +/- 17.8 in the relactation group (p < 0.001). In conclusion, it a clear difference between the two types of milk in this study.

Induced Lactation: A Study of Adoptive Nursing by 240 Women

Abstract: • Induced lactation is breast-feeding without prior pregnancy. Preparation includes breast and nipple stimulation, supplementing the maternal diet, and occasional use of hormones. Infants younger than 8 weeks are more willing to nurse than infants older than 8 weeks. Previous lactation experience is related to increased likelihood of milk production, decreased need for supplemental fluids, and duration of breast-feeding. Tandem nursing an older biological infant and the adoptive infant does not guarantee an increase in milk production sufficient to meet the adoptive infant's needs. Three fourths of the women who took part in this questionnaire survey evaluated their experience positively, regardless of infant age at weaning or need for supplemental fluids. Most respondents stressed the maternal-infant relationship and its enhancement through breast-feeding, rather than milk production, as the reason for attempting induced lactation.

Prevalencia de enteroparasitos, rotavirus y adenovirus en niños aparentemente sanos

Abstract: Para determinar la prevalencia de parasitos intestinales, rotavirus y adenovirus en ninos aparentemente sanos, se realizo el estudio parasitologico de 101 muestras fecales de individuos de uno u otro sexo, con edades comprendidas entre 2 meses y 14 anos, asi como el estudio virologico en 70 muestras de los ninos menores de 5 anos. A cada especimen fecal se le realizo un examen coproparasitologico directo, concentracion de Formol-Eter y coloracion de Kinyoun. Para determinar Rotavirus y Adenovirus se empleo la tecnica de Ensayo Inmunoenzimatico (ELISA). Para el analisis estadistico se utilizo el Ji-cuadrado (χ2) y la prueba Z. Se observo un elevado porcentaje de individuos parasitados (85,15%), los protozoarios mas frecuentes fueron: Blastocystis hominis (52,47%), Giardia lamblia (26,73%) y Entamoeba coli (20,79%) y entre los helmintos Trichuris trichiura (50,49%), Ascaris lumbricoides (48,51%) y Strongyloides stercoralis (7,92%). Se observo una frecuencia de Rotavirus del 2,86% y ausencia de infeccion por Adenovirus. La elevada prevalencia parasitaria demuestra las condiciones de insalubridad de la comunidad, a pesar de ello, lo contrario ocurrio con los virus estudiados. Para Rotavirus quizas influyo la adquisicion de anticuerpos a traves de la lactancia materna, mientras que para Adenovirus entericos, probablemente el desarrollo de anticuerpos a edad temprana

Fatores de Risco e Proteção Associados à Depressão Pós-Parto no Pré-Natal Psicológico

Abstract: Resumo: Esta investigacao teve por objetivos gerais: a) identificar fatores de risco e de protecao associados a Depressao Pos-Parto (DPP); e b) avaliar a contribuicao do Pre-Natal Psicologico (PNP) como programa de prevencao em Saude da Mulher. Para tanto, empreendeu-se uma pesquisa-acao organizada em tres fases, reunindo um total de 198 gestantes. Na ultima fase, as participantes foram distribuidas em Grupo Intervencao – GI (n = 47) e Grupo Controle – GC (n = 29). Para coleta de dados, utilizaram-se: Questionario Gestacional, BAI, BDI-II e EPDS. Os dados foram submetidos a analises estatisticas descritivas e comparativas. Nao foi possivel relacionar variaveis socioeconomicas, participacao no PNP e desejo de gravidez com maior risco de DPP. Em contrapartida, verificou-se tal associacao quanto a gravidez nao planejada e a falta de apoio do pai do bebe. Contrariamente ao GC, nao se constatou associacao entre ansiedade e depressao gestacionais com a DPP no GI. Nesse grupo, 10,64% das puerperas revelaram tendencia para DPP, ao passo que, em GC, 44,83% mostraram tal propensao. Em suma, considera-se que o PNP, somado a fatores de protecao, constitui acao preventiva a ser desenvolvida pelo profissional de Psicologia no contexto do acompanhamento pre e pos-natal.
