Cistos subependimários diagnosticados pelo ultra-som transfontanelar

Objetivos: avaliar a evolução ultra-sonográfica de cistos subependimários (CSE) do ângulo externo dos ventrículos laterais, e a evolução clínica dos pacientes. Comparar os pacientes com CSE isolados e os com CSE associados a outras lesões. Métodos: foram diagnosticados um a vários cistos no ângulo externo de um ou de ambos os ventrículos laterais, por meio de ultra-som transfontanelar (US) de rotina, realizado nos primeiros dias de vida, caracterizando os CSE. Durante o período de 1981-2000, 66 recém-nascidos tiveram CSE evidenciados na UTI neonatal do Hospital de Port-Royal. Foram constituídos dois grupos: G-I, com CSE isolados (n=21), e G-II, com CSE associados a outras lesões (n=45). Resultados: os recém-nascidos do GI apresentaram maior maturidade, melhores condições de nascimento e menor morbidade respiratória em relação a GII. A incidência de malformações congênitas foi elevada em ambos os grupos. Houve baixa taxa de infecção bacteriana e ausência de infecção congênita. Os CSE foram uni ou bilaterais, únicos ou múltiplos (colar de pérolas), sem diferença entre os grupos estudados, e predominaram à esquerda. US seriados foram realizados em 49/66 pacientes (74%), mostrando aumento no tamanho do cisto em 21/49 (45%), no primeiro mês de vida, enquanto 12 CSE (24%) desapareceram. O óbito ocorreu em dez recém-nascidos com lesões neurológica graves (quatro leucomalácias periventriculares, cinco hemorragias peri e intraventriculares), e somente um com hérnia diafragmática não apresentava outras lesões ao US transfontanelar. Conclusões: as características dos CSE não diferiram quando esses estavam associados a outras lesões. O nítido predomínio no lado esquerdo sugere uma etiologia vascular. Foi encontrada uma alta taxa de malformações associadas, alertando para a possibilidade de uma etiologia malformativa. Ambas hipóteses sugerem um desvio de desenvolvimento, e não de uma fetopatia viral.

Effect of Oral Supplementation of the Linoleic and Gammalinolenic Acids on the Diabetic Pregnant Rats

The aim of this work was to evaluate the direct protective action of oral fatty acid supplementation against the deleterious effect of hyperglycemia on maternal reproductive outcomes; fetal growth and development on female Wistar rats. The animals were distributed into four experimental groups: G1= non-diabetic without supplementation (Control group); G2= non-diabetic treated with linoleic (LA) and gammalinolenic acid (GLA) (1 mL of Gamaline-V/day); G3= diabetic without supplementation and G4= diabetic treated with LA and GLA. Diabetes was induced by streptozotocin (40 mg/kg). At day 21 of pregnancy, the gravid uterus was weighed and dissected to count the dead and live fetuses, resorption, implantation, and corpora lutea numbers. The fetuses were analyzed for external and internal anomalies. The treatment with Gamaline-V supplementation to diabetic rats interfered in the maternal reproductive outcome (reduced number of live fetuses and embryonic implantation); however, it protected the deleterious on the incidence of congenital anomalies caused by hyperglycemia.

Resultado perinatal de fetos com malformações do trato urinário

PURPOSE: to evaluate the perinatal outcome of fetuses with congenital anomalies of the urinary tract. METHODS: we reviewed the perinatal outcome of 35 fetuses with congenital anomalies of the urinary tract. The following characteristics related to the uropathy were analyzed: type (hydronephrosis, dysplasia and renal agenesis), side of lesion (bilateral or unilateral), and level of the obstruction (high or low, in hydronephrosis). The perinatal outcome was evaluated according to these characteristics. The data were analyzed by the c² test and by the exact Fisher test. The level of significance was 0.05. RESULTS: the incidence of hydronephrosis was 68.6%. Half of the fetuses had unilateral hydronephrosis. Renal dysplasia occurred in 17.1% of the cases; 83.3% of these were bilateral and 16.7%, unilateral. The incidence of renal agenesis was 14.3%, all bilateral. The fetuses with dysplasia/agenesis had a 91% incidence of oligohydramnios, preterm birth, low birth weight, and death. In the group with bilateral disease the presence of oligohydramnios, preterm birth, low birth weight, death, urinary tract infections, and the need of hospitalization for a period greater than 7 days was significant when compared to the group with unilateral disease. The need of hospitalization for a period greater than 7 days in patients with low obstruction was significantly higher when compared to the patients with high obstruction. CONCLUSIONS: hydronephrosis, bilateral disease, and lower obstruction were the most frequent uropathies. The dysplasia/agenesis group had a worse prognosis when compared with the hydronephrosis group. Bilateral disease had a worse prognosis when compared with the unilateral disease group. In the low obstruction group, the need for a period of hospitalization greater than seven days was higher than in the high obstruction group.

Oral cleft prevention program (OCPP)

Background: Oral clefts are one of the most common birth defects with significant medical, psychosocial, and economic ramifications. Oral clefts have a complex etiology with genetic and environmental risk factors. There are suggestive results for decreased risks of cleft occurrence and recurrence with folic acid supplements taken at preconception and during pregnancy with a stronger evidence for higher than lower doses in preventing recurrence. Yet previous studies have suffered from considerable design limitations particularly non-randomization into treatment. There is also well-documented effectiveness for folic acid in preventing neural tube defect occurrence at 0.4 mg and recurrence with 4 mg. Given the substantial burden of clefting on the individual and the family and the supportive data for the effectiveness of folic acid supplementation as well as its low cost, a randomized clinical trial of the effectiveness of high versus low dose folic acid for prevention of cleft recurrence is warranted.Methods/design: This study will assess the effect of 4 mg and 0.4 mg doses of folic acid, taken on a daily basis during preconception and up to 3 months of pregnancy by women who are at risk of having a child with nonsyndromic cleft lip with/without palate (NSCL/P), on the recurrence of NSCL/P. The total sample will include about 6,000 women (that either have NSCL/P or that have at least one child with NSCL/P) randomly assigned to the 4 mg and the 0.4 mg folic acid study groups. The study will also compare the recurrence rates of NSCL/P in the total sample of subjects, as well as the two study groups (4mg, 0.4 mg) to that of a historical control group. The study has been approved by IRBs (ethics committees) of all involved sites. Results will be disseminated through publications and presentations at scientific meetings.Discussion: The costs related to oral clefts are high, including long term psychological and socio-economic effects. This study provides an opportunity for huge savings in not only money but the overall quality of life. This may help establish more specific clinical guidelines for oral cleft prevention so that the intervention can be better tailored for at-risk women.

Sobrevida e morbidade em prematuros com menos de 32 semanas de gestação na região central do Brasil

OBJETIVO: Avaliar a sobrevida e complicações associadas à prematuridade em recém-nascidos com menos de 32 semanas. MÉTODOS: Estudo prospectivo do tipo coorte. Foram incluídos os nascidos vivos, com idade gestacional entre 25 semanas e 31 semanas e 6 dias, sem anomalias congênitas admitidos em UTI Neonatal, entre 1º de agosto de 2009 e 31 de outubro de 2010. Os recém-nascidos foram estratificados em três grupos: G25, 25 a 27 semanas e 6 dias; G28, 28 a 29 semanas e 6 dias; G30, 30 a 31 semanas e 6 dias, e acompanhados até 28 dias. Foram avaliadas a sobrevida aos 28 dias e a morbidade associadas à prematuridade. Para análise dos resultados, utilizou-se o teste do c², análise de variância, teste de Kruskal-Wallis, razão de risco com intervalo de confiança (IC) e regressão logística múltipla, com significância em 5%. RESULTADOS: A coorte compreendeu 198 prematuros, sendo G25=59, G28=43 e G30=96. O risco de óbito foi significativamente maior em G25 e G28, em relação ao G30 (RR=4,1; IC95% 2,2-7,6 e RR=2,8; IC95% 1,4-5,7). A sobrevida encontrada foi, respectivamente, 52,5, 67,4 e 88,5%. A partir da 26ª semana e peso >700 g, a sobrevida foi superior a 50%. A morbidade foi inversamente proporcional à idade gestacional, exceto para enterocolite necrosante e leucomalácia, que não diferiram entre os grupos. A análise de regressão logística mostrou que a hemorragia pulmonar (OR=3,3; IC95% 1,4-7,9) e a síndrome do desconforto respiratório (OR=2,5; IC95% 1,1-6,1) foram fatores independentes de risco para óbito. Houve predomínio das lesões cerebrais hemorrágicas graves em G25. CONCLUSÕES: Sobrevivência superior a 50% ocorreu a partir da 26ª semana de gravidez e peso >700 g. A hemorragia pulmonar e a síndrome do desconforto respiratório foram preditores independentes de óbito. Há necessidade de identificar e instituir práticas para melhorar a sobrevida de prematuros extremos.

Ulnar ray a/hypoplasia: evidence for a developmental field defect on the basis of genetic heterogeneity. Report of three Brazilian families.

We report on five Brazilian patients from three unrelated families with congenital anomalies of the upper limbs. Ulnar aplasia/hypoplasia was the main reason for examining these patients. Evidence for existence of an ulnar developmental field is based on genetic heterogeneity. Clinical and genetic aspects of the ulnar ray defects are discussed.

Anomalia congênita em vasos da base do coração de um potro

Congenital anomalies of heart and large vessels are among more common found in animals, however rare in horses. This survey describes a cardiac anomaly that presents confluence between aorta wall and lung trunk, ramification of caudal cava vein in left atrium with presence of valve and consequently erroneous position of heart in thoracic cavity of one foal found dead after birth. The diagnostic was carried out for macroscopic finds association during the necropsy and histopathologic exams carried out at School of Veterinary Medicine - Unesp Araçatuba.

Tomografia computadorizada de abdome normal: Estudo retrospectivo das angulações dos hilos renais

OBJECTIVE: To obtain mean angulation values for renal hila in relation to the horizontal plane traced over the right and left spinal erector muscles, considering the center of the lumbar vertebral spine as a parameter for measuring the renal hila angles. MATERIALS AND METHODS: The authors have analyzed 250 abdominal computed tomography studies of both male and female healthy individuals (128 men with mean age 52.45 ± 17.42 years, and 122 women with mean age 54.39 ± 18.27 years), corresponding to 500 renal hila evaluated. The mean angulation of each hilum in relation to the horizontal plane was obtained taking acute angles into consideration. RESULTS: The comparative study have not found any statistically significant difference in acute angles of renal hila between male and female individuals. The statistical analysis demonstrated limits of 40.40° and 44.54° for mean right hilum angulation and 39.91° and 43.23° for mean left hilum angulation, with a confidence interval of 95% CONCLUSION: Renal hila present similar angulation independently of sex. Higher angulation values correspond to hyper-rotation or excessive rotation, and lower angulation values, to incomplete or reverse rotation. © Colégio Brasileiro de Radiologia e Diagnóstico por Imagem.

Growth of preterm low birth weight infants until 24 months corrected age: effect of maternal hypertension

Objective: To evaluate the growth pattern of low birth weight preterm infants born to hypertensive mothers, the occurrence of growth disorders, and risk factors for inadequate growth at 24 months of corrected age (CA).Methods: Cohort study of preterm low birth weight infants followed until 24 months CA, in a university hospital between January 2009 and December 2010. Inclusion criteria: gestational age < 37 weeks and birth weight of 1,500-2,499g. Exclusion criteria: multiple pregnancies, major congenital anomalies, and loss to follow up in the 2nd year of life. The following were evaluated: weight, length, and BMI. Outcomes: growth failure and risk of overweight at 0, 12, and 24 months CA. Student's t-test, Repeated measures ANOVA (RM-ANOVA), and multiple logistic regression were used.Results: A total of 80 preterm low birth weight infants born to hypertensive mothers and 101 born to normotensive mothers were studied. There was a higher risk of overweight in children of hypertensive mothers at 24 months; however, maternal hypertension was not a risk factor for inadequate growth. Logistic regression showed that being born small for gestational age and inadequate growth in the first 12 months of life were associated with poorer growth at 24 months.Conclusion: Preterm low birth weight born infants to hypertensive mothers have an increased risk of overweight at 24 months CA. Being born small for gestational age and inadequate growth in the 1st year of life are risk factors for growth disorders at 24 months CA. (C) 2014 Sociedade Brasileira de Pediatria.

Resíduos sólidos urbanos: impactos socioambientais e perspectiva de manejo sustentável com inclusão social

Com a Rio+20 retoma-se a discussão de estratégias para conciliar desenvolvimento com proteção dos ecossistemas. Um tema apenas tangenciado nessas discussões é o gerenciamento dos resíduos sólidos urbanos. Diante da institucionalização da Política Nacional de Resíduos Sólidos, busca-se contribuir para esse debate, bem como apontar caminhos para o enfrentamento dessa questão, privilegiando a inclusão social. Para isso, foram utilizados documentos e informações sobre a gestão de resíduos sólidos, e a literatura científica especializada. Observa-se que o inadequado gerenciamento dos resíduos sólidos gera impactos imediatos no ambiente e na saúde, assim como contribui para mudanças climáticas. Considerando as limitações das opções de destinação final para os resíduos, é imprescindível minimizar as quantidades produzidas por meio da redução, reutilização e reciclagem. Nesse contexto, destaca-se o papel dos catadores, que vêm realizando um trabalho de grande importância ambiental. Dadas as fragilidades desse segmento populacional, é preciso delinear políticas públicas que tornem a atividade de catação mais digna e com menos riscos e que, ao mesmo tempo, garantam renda, para assim caminhar rumo a um desenvolvimento mais saudável, justo e sustentável.

Vaginal progesterone in women with an asymptomatic sonographic short cervix in the midtrimester decreases preterm delivery and neonatal morbidity: a systematic review and metaanalysis of individual patient data

OBJECTIVE: To determine whether the use of vaginal progesterone in asymptomatic women with a sonographic short cervix (<= 25 mm) in the midtrimester reduces the risk of preterm birth and improves neonatal morbidity and mortality. STUDY DESIGN: Individual patient data metaanalysis of randomized controlled trials. RESULTS: Five trials of high quality were included with a total of 775 women and 827 infants. Treatment with vaginal progesterone was associated with a significant reduction in the rate of preterm birth <33 weeks (relative risk [RR], 0.58; 95% confidence interval [CI], 0.42-0.80), <35 weeks (RR, 0.69; 95% CI, 0.55-0.88), and <28 weeks (RR, 0.50; 95% CI, 0.30-0.81); respiratory distress syndrome (RR, 0.48; 95% CI, 0.30-0.76); composite neonatal morbidity and mortality (RR, 0.57; 95% CI, 0.40-0.81); birthweight <1500 g (RR, 0.55; 95% CI, 0.38-0.80); admission to neonatal intensive care unit (RR, 0.75; 95% CI, 0.59-0.94); and requirement for mechanical ventilation (RR, 0.66; 95% CI, 0.44-0.98). There were no significant differences between the vaginal progesterone and placebo groups in the rate of adverse maternal events or congenital anomalies. CONCLUSION: Vaginal progesterone administration to asymptomatic women with a sonographic short cervix reduces the risk of preterm birth and neonatal morbidity and mortality.
