There is little information about the knowledge and attitudes of physicians regarding oral care. This study aimed to assess the knowledge and attitudes of obstetricians about the relationship between periodontal disease and preterm/low birth weight. A questionnaire was emailed to members of the Brazilian Federation of Gynecology and Obstetrics (FEBRASGO). The questionnaire elicited both personal information and knowledge and attitudes regarding the relationship between periodontal diseases and preterm labor. A total of 875 obstetricians responded to the questionnaire. The majority of respondents were female (54.1%), resided in the Southeast (45.6%), worked in both the public and private sectors (61.4%), and had over 15 years of experience in obstetrics (48.9%). A large proportion of obstetricians (93.4%) stated that bacteria were associated with periodontal disease, and 94% reported that periodontitis was a condition more severe than gingivitis. In total, over 80% of participating obstetricians reported smoking, preeclampsia, bacterial vaginosis and periodontal disease as risk factors or possible risk factors for preterm birth or low birth weight. A correlation between the experience of the obstetricians and referral of their patients for dental examinations (p < 0.001) was observed. Also, obstetricians who had had their own dental visits more recently were more likely to recommend the same for their patients (p < 0.001). It is concluded that, although obstetricians were aware of the association between gingival inflammation and adverse obstetric outcomes, the attitudes of these professionals were not in agreement with their apparent knowledge regarding periodontal diseases and their possible repercussions.

OBJETIVO: Comparar os níveis de androgênios e densidade mineral óssea (DMO) em mulheres ooforectomizadas (OOF) e não ooforectomizadas (NOOF) na pós-menopausa. Quarenta mulheres (53,9 ± 4 anos), 20 OOF e 20 NOOF foram selecionadas. MÉTODOS: Testosterona total (TT), testosterona livre (TL), androstenediona (AN), deidroepiandrosterona (DHEA) e sulfato de deidroepiandrosterona (DHEA-S) foram dosados. DMO foi avaliada em 16 NOOF e 14 OOF. RESULTADOS: Não houve diferença entre os grupos com relação à idade, ao índice de massa corporal (IMC) e ao tempo de menopausa. Concentração média de TT e TL foi duas vezes maior em mulheres NOOF (60,91 versus 30,17 ng/dL, p = 0,0001; 1,00 versus 0,48 pg/mL, p = 0,003). Não houve diferença na DMO. Houve correlação inversamente significativa entre IMC e TT, r = -0,3; p = 0,05, e do tempo de menopausa com AN (r = -0,35; p = 0,02), DHEA, (r = 0,3; p = 0,01). CONCLUSÃO: Ooforectomia bilateral resultou em deficiência androgênica mais severa que a menopausa natural, sem comprometimento da massa óssea.

OBJECTIVE: Compare levels of androgens and bone mineral density (BMD) of ovariectomized (OVX) and non-ovariectomized (NOVX) postmenopausal women. Forty women, 20 OVX and 20 NOVX, (53.9 ± 4 years) were selected. METHODS: Total testosterone (TT), free testosterone (FT), androstenedione (AN), dehidroepiandrostenedione (DHEA) and its sulfate (DHEA-S) were measured. BMD was measured in 14 OVX and 16 NOVX. RESULTS: No differences between groups with regard to age, body mass index (BMI) and time since menopause were found. Mean levels of TT and FT were two-fold higher in NOVX group (60.91 versus 30.17 ng/dL, p = 0.0001; 1.00 versus 0.48 pg/mL, p = 0.003). BMD was not different between groups. Inverse correlations were found between BMI and TT (r = -0.3; p = 0.05); time since menopause and AN (r = -0.35; p = 0.02) and time since menopause and DHEA (r = -0.3; p = 0.01). CONCLUSION: Bilateral ovariectomy leads to a more severe androgen deficiency than natural menopause in postmenopausal women and did not compromise bone mass.

CONTEXTO: O transplante hepático bem sucedido não apenas cura a doença hepática de base, mas rapidamente restaura a libido e a fertilidade nas receptoras. Apesar do número crescente de gestações bem sucedidas em mulheres transplantadas, tais gestações são consideradas de alto risco, pois associam-se a maior morbidade materno-fetal. AQUISIÇÃO DE EVIDÊNCIA: Revisão de literatura indexada no MEDLINE (1978-2007) foi realizada empregando-se os termos "transplante hepático", "gravidez", imunossupressores", "função sexual". Artigos de revisão, estudos clínicos retrospectivos, estudos clínicos de seguimento de séries de pacientes e artigos originais, contendo observações de ciência básica relevante, foram incluídos. RESULTADOS: Embora não haja padronização dos cuidados na gravidez em receptoras de transplante hepático, existem algumas "regras de ouro" para aumentar a possibilidade de evolução materno-fetal favorável. A maioria dos centros recomenda adiar a gravidez pelo menos por 1 ano após o transplante hepático, quando habitualmente a paciente se encontra com imunossupressão estabilizada e função hepática adequada, sem evidência de disfunção renal ou hipertensão arterial não controlada. Devido à frequência aumentada de prematuridade, baixo peso ao nascer, hipertensão arterial e pré-eclâmpsia, a gestação após transplante hepático é considerada de alto risco e deve ser rigorosamente monitorada por equipe multidisciplinar, incluindo obstetra com experiência em gestações de alto risco. Controle frequente dos níveis séricos dos imunossupressores é prudente para evitar rejeição do enxerto e drogas com potencial teratogênico devem ser interrompidas. Aleitamento materno não é incentivado devido à excreção das drogas imunossupressoras no leite materno. CONCLUSÕES: Gestação bem sucedida é a regra após o transplante hepático desde que sejam observados certos cuidados. Controle médico rigoroso por equipe multidisciplinar experiente aumenta as chances de evolução materno-fetal favorável.

CONTEXT:- Successful liver transplantation not only treats the underlying liver disease but also restores libido and fertility in female recipients. Although reports of successful pregnancy after liver transplantation continue to increase, these pregnancies are considered of high-risk because they are associated with increase maternofetal morbidity. EVIDENCE ACQUISITION: A MEDLINE search (1978-2007) was conducted using the terms "liver transplantation", "pregnancy", "immunosupressive agents", "sexual function". Reviews, retrospective series, long-term clinical follow-up of case series and original articles containing basic scientific observations were included. RESULTS: Although no formal guidelines have been established there are some "golden rules" to improve the probability of favorable maternal and fetal outcome. Most transplant centers recommend to delay pregnancy for at least 1-year after transplantation. The recipient should be on a stable immunosuppression regimen, with good graft function and no evidence of renal dysfunction or uncontrolled arterial hypertension. Considering the increased incidence of prematurity, low birth weight, hypertension and preeclampsia reported during pregnancy post-LT, these high-risk patients should be managed by a multidisciplinary team, including an obstetrician specialized in high-risk pregnancies. Carefully monitoring of immunosuppressive drugs serum level is prudent to avoid graft rejection episodes and drugs with teratogenic potential should be discontinued. Breastfeeding is usually not recommended. CONCLUSIONS: Successful pregnancies are the rule after liver transplantation. A carefully monitoring by an experience multidisciplinary team increases the chances of favorable maternofetal outcome.
