Analisamos o exame video-polissonográfico de 26 recém-nascidos de termo (RNT) com 24 horas de vida. Os RN tinham exame neurológico e ultrassonográfico cerebral normais e apresentaram período perinatal isento de complicações. Foram subdivididos em dois grupos, um controle constituído de 11 RNT com peso adequado para a idade gestacional; e um grupo de 15 RN com peso abaixo do esperado para o termo (RNT-PIG). do segundo grupo, 13 RN apresentaram algum tipo de alteração ao exame video-polissonográfico. As alterações mais frequentes foram na arquitetura do sono, 11 casos, e no comportamento, em que oito RN apresentaram número excessivo de sobressaltos (startle) em relação ao grupo controle e dois RN uma atividade motora reduzida. Os resultados deste estudo demonstram a utilidade da video-polissonografia quando aplicada a RNT-PIG. O exame mostrou-se sensível em detectar diferenças no comportamento, arquitetura do sono e padrão eletrencefalográfico dos RNT-PIG quando comparados ao grupo controle.

OBJETIVO: Avaliar as características antropométricas, a morbidade e mortalidade de recém-nascidos (RN) prematuros nascidos vivos de mães hipertensas em função da presença ou não de diástole zero (DZ) ou reversa (DR) na doplervelocimetria arterial umbilical. MÉTODOS: Estudo prospectivo, envolvendo RN prematuros nascidos vivos de gestantes hipertensas, com idade gestacional entre 25 e 33 semanas, submetidas à doplervelocimetria da artéria umbilical nos 5 dias que antecederam o parto, realizado no Hospital do Distrito Federal, entre 1º de novembro de 2009 e 31 de outubro de 2010. Os RN foram estratificados em dois grupos, conforme o resultado da doplervelocimetria da artéria umbilical: Gdz/dr=presença de diástole zero (DZ) ou diástole reversa (DR) e Gn=doplervelocimetria normal. Medidas antropométricas ao nascimento, morbidades e mortalidade neonatal foram comparadas entre os dois grupos. RESULTADOS: Foram incluídos 92 RN, assim distribuídos: Gdz/dr=52 RN e Gn=40 RN. No Gdz/dr a incidência de RN pequenos para idade gestacional foi significativamente maior, com risco relativo de 2,5 (IC95% 1,7‒3,7). No grupo Gdz/dr os RN permaneceram mais tempo em ventilação mecânica mediana 2 (0‒28) e no Gn mediana 0,5 (0‒25), p=0,03. A necessidade de oxigênio aos 28 dias de vida foi maior no Gdz/dr do que no Gn (33 versus10%; p=0,01). A mortalidade neonatal foi maior em Gdz/dr do que em Gn (36 versus 10%; p=0,03; com risco relativo de 1,6; IC95% 1,2 - 2,2). Nessa amostra a regressão logística mostrou que a cada 100 gramas a menos de peso ao nascer no Gdz/dr a chance de óbito aumentou 6,7 vezes (IC95% 2,0 - 11,3; p<0,01). CONCLUSÃO: em RN prematuros de mães hipertensas com alteração na doplervelocimetria da artéria umbilical a restrição do crescimento intrauterino é frequente e o prognóstico neonatal pior, sendo elevado o risco de óbito relacionado ao peso ao nascimento.

O presente trabalho objetivou avaliar a função renal de dez cães adultos saudáveis submetidos à administração de doses terapêuticas do antifúngico anfotericina B, cuja utilização tem sido limitada pelo seu elevado potencial nefrotóxico, e avaliar o método laboratorial mais sensível e precoce de diagnóstico de lesão renal. Foram realizadas, diariamente, urinálise, excreção fracionada de sódio e potássio, dosagem sérica de creatinina e uréia e atividade urinária de gama-glutamiltransferase (GGT). Concluiu-se que a anfotericina B provoca lesões nos túbulos proximal e distal, induzindo acidose tubular renal do tipo I e Diabetes insipidus nefrogênico em cães. Avaliação da função renal, preferencialmente por dosagens de creatinina, uréia e potássio séricos, é recomendada antes de cada aplicação do fármaco. A densidade urinária foi o parâmetro mais precocemente alterado pela lesão renal. A GGT urinária não foi eficaz para o diagnóstico precoce de lesão induzida por anfotericina B.

O objetivo desta revisão da literatura é discutir a importância da educação em saúde como estratégia de promoção de saúde bucal no período gestacional. Foram estudadas as manifestações bucais mais comuns na gestação, concluindo-se que, embora a gestação por si só não seja responsável por tais manifestações como, por exemplo, a cárie dentária e a doença periodontal, faz-se necessário o acompanhamento odontológico no pré-natal, considerando-se que as alterações hormonais da gravidez poderão agravar as afecções já instaladas. Destacou-se na promoção de saúde bucal na gestante a educação em saúde bucal, considerando-a parte importante do Programa de Atenção à Saúde da Mulher, conforme recomendado pelas atuais Diretrizes da Política Nacional de Saúde Bucal. Considera-se que, por meio de ações de educação em saúde bucal, desenvolvidas no pré-natal por uma equipe multiprofissional, orientada por um cirurgião-dentista, a mulher poderá se conscientizar da importância de seu papel na aquisição e manutenção de hábitos positivos de saúde bucal no meio familiar e atuar como agente multiplicador de informações preventivas e de promoção de saúde bucal.

Birth weight and placental weight of 566 newborns were determined. The newborns were classified by birth weight and gestational age in seven groups: term, preterm and postterm newborns with weight appropriate for gestational age; term and postterm newborns small for gestational age; term and preterm newborns large for gestational age. The differences in the mean placental weight in the preterm, term and postterm newborns with weight appropriate for gestational age were not significant. After 34 weeks of gestation there was little increase in placental weight. The mean placental weight of newborns large for gestational age was significantly different from that of term newborns appropriate for gestational age. In the term and postterm newborns small for gestational age the mean placental weight was significantly different from term and postterm newborns appropriate for gestational age. These findings suggest that newborns with an appropriate intrauterine growth have little increase in placental weight in the gestational period. Gestational age is not an important factor in determining placental weight in this period. Nutrition is important for placental growth-retarded infants have small placentas and large-for-date infants have large placental weight.

The present study was undertaken to determine the importance of socioeconomic factors (family income), urban or rural family location, parity, maternal age, the presence of maternal and fetal pathologies as well as placental abnormalities on the weight and gestational age of 566 newborns. The highest incidence of newborns with low birth weight for gestational age was significantly more frequent in urban populations when the mothers were from low socio-economic levels. In mothers from low socioeconomic levels infants with low birth weight for gestational age were seen in greater proportion among primaparas and had a tendency to be higher in mothers aged less than 20 years; prematurity was highest in mothers ≥ 30 years old and significantly higher from the 8th gestation on. Maternal and fetal pathologies emphasized these characteristics and placental pathologies were not correlated with the distribution of weight and length of gestation. In mothers of high socioeconomic levels age and parity were not correlated with weight and gestational age of the newborns.

The authors studied gross and histological abnormalities of placentae from 566 newborns, grouped according to birth and gestational age. The relation of hemorragic abnormalities, infections of membranes and placental tissue, chronic infections, calcifications, hydropic degeneration of villi, chorangioma, cysts, vascular lesions (endarteritis) with newborn weight, length of gestation and intrauterine growth retardation were determined. We concluded that lesions due to disturbances of placental blood flow were significantly more frequent in placentae from term newborns small for gestational age; villi hydropic degenerations were more frequent in placentae of pre-term newborns appropriate for gestational age. Chronic infections had a tendency to be greater in placentae from infants with diminished intrauterine growth. Term newborns small for gestational age had greater proportions of placental abnormalities than the other groups.

PURPOSE: to evaluate the insulin therapy protocol and its maternal and perinatal outcome in patients with clinical or gestational diabetes in a high risk reference service. METHODS: descriptive and prospective study including 103 pregnant women with gestational or clinical diabetes treated with insulin and attended by the reference service from October 2003 to December 2005. Gemellarity, miscarriages, unfinished prenatal care and deliveries not attended by the service were excluded. The gestational age at the beginning of the treatment, dosage, doses/day, increment of insulin (UI/kg), glycemic index (GI) and perinatal outcomes were compared. ANOVA, Fisher's exact test and Goodman's test considering p<0.05 were used. RESULTS: multiparity (92 versus 67.9%), pre-gestational body mass index (BMI) >25 kg/m 2 (88 versus 58.5%), weight gain (WG) <8 kg (36 versus 17%) and a high increment of insulin characterized the gestational diabetes. For the patients with clinical diabetes, despite the highest GI (120 mg/dL (39.2 versus 24%)) at the end of the gestational period, insulin therapy started earlier (47.2 versus 4%), lasted longer (56.6 versus 6%) and higher doses of insulin (92 versus 43 UI/day) were administered up to three times a day (54.7 versus 16%). Macrosomia was higher among newborns from the cohort of patients with gestational diabetes (16 versus 3.8%), being the only significant neonatal outcome. There were no neonatal deaths, except for one fetal death in the cohort of patients with clinical diabetes. There were no differences in the other neonatal complications in both cohorts, and most of the newborns were discharged from hospital up to seven days after delivery (46% versus 55.8%). CONCLUSIONS: the analysis of these two cohorts has shown differences in the insulin therapy protocol in quantity (UI/day), dosage (UI/kg weight) and number of doses/day, higher for the clinical diabetes cohort, and in the increment of insulin, higher for the gestational diabetes cohort. Indirectly, the quality of maternal glycemic control and the satisfactory perinatal outcome have proven that the treatment protocol was adequate and did not depend on the type of diabetes.

Objective: To assess the knowledge of women and the instructions received on breastfeeding during pregnancy and after childbirth, and their influence on breastfeeding practice. Method: This study was a longitudinal investigation following 84 pairs of mothers and babies from pregnancy through the sixth month of baby's life. In the first phase of the research, interviews were made with the pregnant women at home and at Basic Health Units to collect information about their intentions and knowledge of breastfeeding. In the second phase of the research, mothers and babies were followed up from the first to sixth month of baby's life to record the difficulties of breastfeeding and reasons for weaning. Results: In the first month, 94.3% (82) of the babies were breastfed, but only 49.4% (43) were breastfed exclusively. At the end of the sixth month of life, 43.7% (38) of the babies had already been weaned. No mother breastfed exclusively her baby within the sixth month. During pregnancy, 60.7% (51) of the mothers had no instructions about breastfeeding and 83.4% (70) of the mothers received instructions on breastfeeding after childbirth. Most mothers (76.2%) knew about the ideal breastfeeding period. Seventy-three (86.9%) mothers believed that breastfeeding was beneficial for the baby, but only 41 (48.8%) of them really breastfed. Only 11 (13.1%) mothers were followed up by the public health system team during lactation. Conclusion: Although most women had been instructed during pregnancy or after childbirth and had knowledge of breastfeeding, early weaning occurred. Advising is important, but the support and follow up of the mothers are of utmost importance for a successful breastfeeding practice.
