OBJETIVO: Conhecer os motivos de gestantes para o aleitamento materno. MÉTODOS: É um estudo qualitativo realizado com 164 gestantes assistidas no pré-natal em dois Centros de Saúde na região central da cidade de São Paulo. Os dados foram coletados por meio de entrevistas semi-estruturadas sobre motivação para amamentar. As narrativas foram organizadas em planilha eletrônica em busca de categorias. RESULTADOS: As principais categorias identificadas estavam relacionadas à saúde da criança, da mulher e aos benefícios da prática de amamentar e do leite materno. A maioria das mulheres (98,8%) foi favorável à amamentação. Benefícios à saúde da criança foi o motivo mais freqüente (73,8%). CONCLUSÃO: A motivação ao aleitamento materno foi centrada nos benefícios à saúde da criança. A amamentação é valorizada independentemente da vontade materna.

Adoption in Brazil has long been related to practices of not disclosing the child`s history and origins, which become a family secret. As a consequence, most couples who apply for adoption prefer newborns. Late adoption is still an uncommon practice and requires a `family project` which accepts a different family model, new meanings of motherhood and fatherhood, and different ways of building affectionate bonds. It is important to investigate how a man and a woman become parents under those circumstances. This study aimed to follow up the emergence of adoption, motherhood and fatherhood meanings, in the discursive practices involved in the construction of adoptive parenthood in the Brazilian setting. This paper presents important meanings regarding parenthood produced by a couple who adopted two sisters, aged 4 and 5 years. Analysis revealed that to better understand the late adoption process, the meanings that emerge in the discursive practices should be considered. Those meanings pervade and circumscribe the family relationships, influencing how the individuals constitute their roles in the family. It is through the analysis of this dialogical process of construction that it is possible to identify the challenges in late adoption and to unravel the process of constructing affectionate relationships.

Bazex - Dupre - Christol syndrome is a rare genodermatosis with cancer predisposition, characterized by follicular atrophoderma, multiple milia, congenital hypotrichosis, hypohidrosis and basal cell malformations that include nevoid basal cell carcinomas of early onset. We present two patients with this syndrome, a 1-year-old boy with diffuse scalp and eyebrows alopecia, milia papules on the face, ears, trunk, and limbs. Hypohidrosis was observed on his trunk and head. His 16-year-old mother had identical changes since childhood, with hair fragility, and multiple atrophic ""ice pick"" follicular depressions on the dorsa of her hands. She also had a basal cell carcinoma on her face. Microscopic examination of hairs from the mother revealed abnormalities such as diameter irregularities, broken shafts, trichorrexis nodosa and pili bifurcatti. Pili bifurcatti is an uncommon hair shaft dysplasia that has not before been observed in Bazex - Dupre - Christol syndrome.

The present study was designed to explore the correlation between the frequency of micronuclei in Trad-MN, measured across 28 biomonitoring stations during the period comprised between 11 of May and 2 of October, 2006, and adjusted mortality rates due to cardiovascular, respiratory diseases and cancer in Sao Jose dos Campos, Brazil, an area with different sources of air pollution. For controlling purposes, mortality rate due to gastrointestinal diseases (an event less prone to be affected by air pollution) was also considered in the analysis. Spatial distribution of micronuclei frequency was determined using average interpolation. The association between health estimators and micronuclei frequency was determined by measures of Pearson`s correlation. Higher frequencies of micronuclei were detected in areas with high traffic and close to a petrochemical pole. Significant associations were detected between micronuclei frequency and adjusted mortality rate due to cardiovascular diseases (r = 0.841, p = 0.036) and cancer (r = 0.890, p = 0.018). The association between mortality due to chronic obstructive pulmonary diseases was positive but did not reach statistical significance (r = 0.640, p = 0.172), probably because of the small number of events. Gastrointestinal mortality did not exhibit significant association with micronuclei frequency. Because the small number of observations and the nature of an ecological study, the present findings must be considered with caution and considered as preliminary. Further studies, performed in different conditions of contamination and climate should be done before considering Trad-MN in the evaluation of human health risk imposed by air pollutants.

P>Allergens can be maternally transferred to the fetus or neonate, though it is uncertain how this initial allergen exposure may impact the development of allergy responses. To evaluate the roles of timing and level of maternal allergen exposure in the early life sensitization of progeny, female BALB/c mice were given ovalbumin (OVA) orally during pregnancy, lactation or weekly at each stage to investigate the immunoglobulin E (IgE) antibody production and cellular responsiveness of their offspring. Exposure to OVA during pregnancy was also evaluated in OVA-specific T-cell receptor (TCR) transgenic (DO11.10) mice. The effect of prenatal antigen exposure on offspring sensitization was dependent on antigen intake, with low-dose OVA inducing tolerance followed by neonatal immunization that was sustained even when pups were immunized when 3 weeks old. These offspring received high levels of transforming growth factor-beta via breastfeeding. High-dose exposure during the first week of pregnancy or perinatal period induced transient inhibition of IgE production following neonatal immunization; although for later immunization IgE production was enhanced in these offspring. Postnatal maternal antigen exposure provided OVA transference via breastfeeding, which consequently induced increased offspring susceptibility to IgE antibody production according to week post-birth. The effect of low-dose maternal exposure during pregnancy was further evaluated using OVA transgenic TCR dams as a model. These progeny presented pronounced entry of CD4(+) T cells into the S phase of the cell cycle with a skewed T helper type 2 response early in life, revealing the occurrence of allergen priming in utero. The balance between tolerance and sensitization depended on the amount and timing of maternal allergen intake during pregnancy.

Double aneuploidy, (48,XXY,+21) of maternal origin in a child born to a 13-year-old mother: evoluation of the maternal folate metabolism: The occurrence of non-mosaic double trisomy is exceptional in newborns. In this paper, a 48,XXY,+21 child, the parental origin of the extra chromosomes and the evaluation of the maternal folate metabolism are presented. The infant was born to a 13-year-old mother and presented with the typical clinical features of Down syndrome (DS). The origin of the additional chromosomes was maternal and most likely resulted from errors during the first meiotic division. Molecular analysis of 12 genetic polymorphisms involved in the folate metabolism revealed that the mother is heterozygous for the MTHFR C677T and TC2 A67G polymorphisms, and homozygous for the mutant MTRR A66G polymorphism. The maternal homocysteine concentration was 4.7 mu mol/L, a value close to the one considered as a risk factor for DS in our previous study. Plasma methylmalonic acid and serum folate concentrations were 0.17 mu mol/L and 18.4 ng/mL, respectively. It is possible that the presence of allelic variants for the folate metabolism and Hey concentration might have favored errors in chromosomal disjunction (hiring gametogenesis in this young mother. To our knowledge, this is the first patient with non-mosaic Down-Klinefelter born to a teenage mother, resulting from a rare fertilization event combining an abnormal 25,XX,+21 oocyte and a 23,Y spermatozoon.

Background/Objectives: Vitamin A deficiency (VAD) is a major public health problem. The supplementation of lactating women could be an effective strategy to combat it. The objective of this study was to assess the impact of maternal vitamin A supplementation on the mother-infant pair. Subjects/Methods: This was a double blind, placebo-controlled randomized clinical assay in which 33 women received 200 000 IU of vitamin A and 33 women received soy oil between 20th and 30th postpartum days. Maternal blood and milk samples were collected immediately before supplementation and 3 months after delivery, when blood was also collected from the babies. Retinol concentrations <= 0.70 mu mol/l in serum and 1.05 mu mol/l in milk were considered to indicate VAD. Results: Increase in serum retinol level was observed in the supplemented group compared with the pre-supplementation levels (1.05 and 1.17 mu mol/l, respectively; P = 0.026) and to the post-supplementation levels of the control group (1.02 mu mol/l; P = 0.032). Reduction in breast milk retinol was observed in the control group compared with the pre-supplementation levels (1.93 and 1.34 mu mol/l, respectively; P<0.0001) and to the post-supplementation levels of the supplemented group (1.56 mu mol/l; P = 0.0003). There was significant difference in the prevalence of VAD in breast milk after supplementation, 55.6% (15/27) in the control group and 16.1% (5/31) in the supplemented group (P = 0.002). VAD was present in 66.1% (39/59) of infants, with mean serum retinol levels of 0.64 +/- 0.30 mu mol/l in the control group and of 0.69 +/- 0.26 mu mol/l in the supplemented group. Conclusions: Supplementation had a positive impact on maternal vitamin A status. No effect on infant status was detectable 2 months after supplementation with a single dose.

OBJETIVO: Apresentar as características clínicas, tratamento cirúrgico e achado histológico de um caso de lipoidoproteinose. DESCRIÇÃO DO CASO: Criança do sexo masculino, cinco anos de idade, branco, que procurou atendimento odontológico na Universidade. A mãe da criança relatou presença de intensa halitose e dificuldade na alimentação e higienização bucal, decorrentes de crescimento gengival generalizado nos arcos dentários superior e inferior. No exame clínico, verificaram-se comprometimento funcional e estético generalizado (rouquidão, artralgia bilateral no joelho e tornozelo, lesões tumorais nas orelhas, entre outros), além de extensa hiperplasia gengival em ambos os arcos dentários. Optou-se pelo tratamento cirúrgico, com remoção do tecido hiperplásico e exodontia de todos os dentes decíduos e de dois permanentes. O exame histopatológico da peça cirúrgica confirmou o diagnóstico de lipoidoproteinose. COMENTÁRIOS: A lipoidoproteinose é uma doença rara caracterizada pela deposição da substância hialina na pele, membranas mucosas e nos órgãos internos. Os sinais que podem surgir após o nascimento, são: rouquidão; lesões pápulo-nodulares na cabeça, pescoço e membros; lesões papulares amareladas nas margens das pálpebras. O curso desta doença é benigno e crônico.

Congenital pathologies are those existing at or dating from birth. Occurrence of congenital cystic lesions in the oral cavity is uncommon in neonates. Eruption cyst (EC) is listed among these unusual lesions. It occurs within the mucosa overlying teeth that are about to erupt and, according to the current World Health Organization (WHO) classification of epithelial cysts of the jaws, EC is a separate entity. This paper presents a case of congenital EC successfully managed by close monitoring of the lesion, without any surgical procedure or tooth extraction. Eruption of the teeth involved, primary central incisors, occurred at the fourth month of age. During this time neither the child nor mother had any complication such as pain on sucking, refusal to feed, airway obstruction, or aspiration of fluids or teeth.

The goals of this research were to estimate the phenotypic correlations among various meat quality traits from a male broiler line and to describe the relation among these variables. Phenotypical correlations were determined among quality traits, isolating the effects of slaughter date, the age of the mother and sex. The evaluated traits were pH measurements taken at time 0 and at 6 and 24 hours after slaughtering, color parameters, water loss due to exudation, thawing and cooking of the meat, and shear force. Important associations (P<0.01) were found to be significant and, in most cases, weak or moderate, varying from -0.35 to 0.28. The initial pH of the meat was not associated (P>0.05) to the other traits of the meat, whereas the pH at 24 hours after slaughter was able of directly interfering with the attributes of the meat, since this trait was inversely related with lightness and water losses, which indicates an effect of pH fall along 24h after slaughtering on protein denaturation. This study demonstrates that the variables of poultry meat quality are related and that there is a phenotypical association between lightness and cooking losses and the other attributes of the meat. The pH at 24 hours after slaughtering, lightness and cooking losses could be efficient meat quality indicators in this broiler line.

Este artigo é resultado de um estudo que analisou a interação e o brincar entre 20 mães e seus filhos com deficiência auditiva, de graus severo e/ou profundo, com idades entre três e seis anos, em rotina de atendimento no Centro de Distúrbio da Audição, Linguagem e Visão do Hospital de Reabilitação de Anomalias Craniofaciais da Universidade de São Paulo. As mães foram entrevistadas e as respostas, analisadas quantitativa e qualitativamente. Os resultados mostraram que a interação com a mãe durante o brincar favorece o desenvolvimento de habilidades sociais para a adequação da criança ao seu meio social, e que as mães carecem de orientações, a fim de que esse espaço seja utilizado mais eficientemente para o aprendizado.

In Velloziaceae, the number of subsidiary cells has been used to characterize species and support groups. Nevertheless, the homology of the stomatal types have not been scrutinized. Stomatal ontogenesis of Vellozia epidendroides and V. plicata, assigned to have tetracytic stomata, and of V. glauca and Barbacenia riparia, assigned to have paracytic stomata, were investigated. In the four species studied, stomata followed perigenic development. Subsidiary cells arise from oblique divisions of neighbouring cells of the guard mother cell (GMC). These cells are elongated and parallel to the longer axis of the stoma. Polar cells show wide variation, following the shape and size of the epidermal cells in the vicinity. Hence, these cells cannot be called subsidiary cells. This wide variation is due to a much higher density of stomata in some regions of the leaf blade. This distribution of stomata forces the development of short polar cells, leading to an apparently tetracytic stomata. In regions of low concentration of stomata, higher spatial availability between the GMCs allows the elongation of polar cells, leading to evident paracytic stomata. Therefore, the four studied species are considered braquiparacytic, questioning the classification of stomata into tetracytic and paracytic in Velloziaceae.

PURPOSE: To verify if uterine cerclage can induce craniosynostosis or any cranial deformity in new born Wistar rats. METHODS: One pregnant female Wistar rat underwent laparotomy on day 18 of gestation and the uterus cervix was closed with a 3-0 nylon suture to avoid delivery, that occurs normally on the 21 day. The suture was released after 48 hours beyond the normal gestation period. The female rat delivered 11 pups. Six surviving rats from the delivery (group A - constrained group). Two rats were born from another mother and in the same age were used as control group (group B - 2 nonconstrained controls) were allowed to grow. They were sacrificed 1.2 years after their birth all the eight animals. Linear measurement, routine histology and computed tomography of the skull were performed at the time of their death to evaluate the cranial asymmetries by mesurements of the anatomical landmarks of the craniofacial skeleton of the rats on the two groups and compared then. RESULTS: We did not observe statistically significant differences in any of the compared measurements (p>0.05) obtained through the morphologic and radiologic methods. Histologic examinations did not reveal any sign of premature fusion or suture imbrications. Critical decrease in longitudinal body size was noticed as the limbs too in all the animals of group A. CONCLUSION: Constriction of uterine cervix leads to fetus suffering, even death for a few animals, associated to small body size, but not to craniosynostosis.

O presente artigo tem como objetivo refletir acerca do conceito de transmissão psíquica entre gerações, especificamente de uma modalidade - a transmissão psíquica transgeracional - e sua influência na construção das subjetividades individuais e dos vínculos familiares, enfatizando-se aqui o vínculo mãe-filha como gerador de sintomas na criança e conflitos no âmbito familiar, através de um relato clínico de uma psicoterapia psicanalítica vincular, segundo os referenciais de Eiguer (2006) e Berenstein e Puget (1997, 2005). A apresentação do caso clínico permite discutir, ainda, a relação entre a transmissão psíquica transgeracional e o estabelecimento da “maternagem”, bem como os resultados obtidos ao longo de todo o processo psicoterápico. A finalidade desse espaço terapêutico familiar é a de propiciar transformações frente ao legado geracional, promovendo o surgimento de uma subjetividade nova, impulsionadora de vida.
