Frequency of seropositivity to Toxocara canis in children of different socioeconomic strata
Para estudar a freqĂŒĂȘncia da infecção pelo Toxocara canis em crianças de classes sociais diferentes de BrasĂlia, Brasil, foram testados soros de 602 crianças de ambos os sexos, de 1 a 12 anos, distribuĂdas em dois grupos representativos de condiçÔes socioeconĂŽmicas distintas. As amostras do primeiro grupo foram obtidas em laboratĂłrio pĂșblico que atende bairros pobres. As do segundo grupo foram colhidas em laboratĂłrio privado, que serve Ă classe mĂ©dia. Os anticorpos anti-Toxocara foram detectados pelo mĂ©todo ELISA, com antĂgenos de Toxocara canis, e absorção com antĂgenos do Ascaris suum. A prevalĂȘncia de soropositividade foi de 21,8% (66/302) no primeiro grupo e de 3% (9/300) no segundo (p<0,0001). NĂŁo houve diferença quanto ao gĂȘnero ou idade das crianças. Os resultados sugerem significativa prevalĂȘncia de toxocarĂase na população infantil de BrasĂlia, com predomĂnio nas classes sociais menos favorecidas economicamente. __________________________________________________________________________________________ ABSTRACTFrequency of seropositivity for Toxocara in children from different socioeconomic strata in the city of Brasilia (Brazil) was measured. Six hundred and two children of both sexes, aged one to 12 years were distributed in two socioeconomically distinct groups. The samples of sera of the first group were obtained from blood drawn for routine tests in the laboratory of a public hospital attending children from low-income families. Samples from the second group were obtained from private laboratories attending children from middle-class families. Antitoxocara antibodies were detected by ELISA, using Toxocara canis excretory-secretory antigens previously absorbed with Ascaris suum extract. The prevalence of seropositivity was 21.8% (66/302) in the first group and 3% (9/300) in the second (p< 0.0001). No differences in frequency according to age or sex could be detected. Our results suggest a high prevalence of childhood toxocariasis in Brasilia, with children from lower income brackets being the most affected

Le Centre de référence sur les agents tératogÚnes (CRAT) : une structure pionniÚre
Le Centre de référence sur les agents tératogÚnes (CRAT), fondé en 1975, premier
organisme national et international consacré spécifiquement aux médicaments chez la femme
enceinte, a innovĂ© en crĂ©ant une structure dâinformation et de conseil destinĂ©e aux
professionnels de santĂ©, une mĂ©thodologie dâĂ©valuation des risques, une mĂ©thodologie de
recueil des donnĂ©es cliniques assortie dâune base de donnĂ©es de plus de 50 000 grossesses
exposées à des agents exogÚnes, en créant le site www.lecrat.org accessible à tous, et en
initiant le groupe de travail « reproduction, grossesse et allaitement » Ă lâAgence
française de sécurité sanitaire des produits de santé (Afssaps)/ Agence nationale de
sécurité du médicament et des produits de santé (ANSM), ainsi que le réseau européen
European network teratology information services (ENTIS). Ces
innovations constituent une avancée considérable, et contribuent à une meilleure prise en
charge des femmes enceintes et de leurs nouveau-nĂ©s, ainsi quâĂ la surveillance et la
dĂ©tection dâalertes. Le CRAT se tourne Ă©galement vers les risques des mĂ©dicaments sur la
fertilitĂ© masculine et fĂ©minine, et lâimpact des expositions paternelles sur la
descendance
Bedaquiline and Linezolid for Extensively Drug-Resistant Tuberculosis in Pregnant Woman
A woman with extremely drug-resistant tuberculosis treated with a drug regimen including linezolid and bedaquiline during her last 3 weeks of pregnancy gave birth to a child without abnormalities. No fetal toxicities were noted by 2 years after delivery. This drug combination might be safe during the late third trimester of pregnancy

Pregnancy outcome after first trimester exposure to ionizing radiations
International audienceOBJECTIVE: To evaluate the effects of ionizing radiation exposure during the first trimester of pregnancy in usual clinical situations.STUDY DESIGN: We conducted a prospective observational cohort study using data collected between 1987 and 2014. This database was authorized by the French "Commission Nationale de l'Informatique et des LibertĂ©s". The exposed group consisted of 319 pregnant women exposed to sub diaphragmatic ionizing radiations for diagnostic purposes, during the first trimester of pregnancy, and the control group consisted of 319 pregnant women without any exposure or exposed to non-teratogenic agents. Data on maternal history and radiations exposure were collected on first contact, and pregnancy outcomes were documented at follow-up. An univariate analysis was performed to compare both groups for the main outcomes.RESULTS: Exposure to sub diaphragmatic ionizing radiation for diagnosis purpose (median fetal dose of 3.1âmGy [0.2-130.0]) during the first trimester of pregnancy was not significantly associated with an increased risk of malformations (1.5% vs 1.8%, pâ=â1.00), miscarriage (7.8% vs 7.2%, pâ=â0.88), in utero fetal death (0.3% vs 0%, pâ=â1.00) or fetal growth restriction (5.4% vs 3.5%, pâ=â0.62).CONCLUSION: Pregnant women exposed to irradiant diagnostic procedures do not present a higher risk of malformations, miscarriage, in utero fetal death or fetal growth restriction and should be reassured, even if the examination focused on the pelvis
