Psychological preparation reduces preoperative anxiety in children. Randomized and double-blind trial / Preparação psicológica reduz ansiedade pré-operatória de crianças. Ensaio randomizado e duplamente encoberto

Abstract Objective: To verify the effect of psychological preparation on the relief of preoperative anxiety in children and to correlate parents' and children's levels of anxiety. Method: After the approval of the institutional Research Ethics Committee and written consent of the children's parents or guardians, 118 children of both genders were prospectively selected, aged between 2 and 8 years, physical condition classification ASA I, who were treated in the pre-anesthetic evaluation ambulatory of the University Hospital and who underwent ambulatory surgeries at the same hospital. Two controlled groups of 59 children were randomized: control group basic preparation and psychological preparation group. On the day of surgery, all selected children were evaluated regarding their level of anxiety using the modified Yale Preoperative Anxiety Scale and their parents were evaluated regarding their level of anxiety through the Visual Analog Scale. The evaluator was blinded to which study group the child and family member belonged to. Results: Nine children and their family members were excluded per group when the results were analyzed. Children from the prepared group showed significant reductions in their level of anxiety in relation to the control group (p = 0.04). There was no correlation between the level of anxiety of children and their parents' levels (p = 0.78). Conclusion: The psychological preparation was effective in reducing the level of anxiety of children. However, there was no relation between the level of anxiety of children and their parents' level.

Resumo: Objetivos: Verificar o efeito da preparação psicológica no alívio da ansiedade pré-operatória de crianças e avaliar se há correlação com a ansiedade dos pais. Método: Após a aprovação do Comitê de Ética e Pesquisa da Faculdade de Medicina e obtenção do consentimento pelos responsáveis dos pacientes, foram selecionadas prospectivamente 118 crianças, de ambos os sexos, entre dois e oito anos, classificação de estado físico ASA I, atendidas no ambulatório de avaliação pré-anestésica do Hospital Universitário e submetidas a cirurgias ambulatoriais. Foram randomizados dois grupos controlados de 59 crianças: grupo de preparação básica e grupo de preparação psicológica. No dia da cirurgia, todas as crianças foram avaliadas em relação ao seu grau de ansiedade através da Escala de Ansiedade Pré-operatória de Yale Modificada e seus pais, avaliados quanto ao seu nível de ansiedade pela Escala Visual Analógica. O avaliador era cego sobre qual grupo do estudo a criança e seu familiar pertenciam. Resultados: Na análise dos resultados, foram excluídas nove crianças e familiares de cada grupo. As crianças do grupo preparado tiveram reduções significativas no grau de ansiedade em relação ao grupo controle, (p = 0,04). Não houve correlação entre os graus de ansiedade das crianças e seus pais (p = 0,78). Conclusão: A preparação psicológica foi eficaz na redução do grau de ansiedade das crianças no momento da cirurgia. Não houve, entretanto, relação entre os graus de ansiedade dos pais e seus filhos.

Pentraxin-3 concentration in the amniotic fluid of women at term, in spontaneous preterm labor and when not in labor.

OBJECTIVE: To evaluate the concentration of PTX3 in amniotic fluid (AF) during the final weeks of normal pregnancies and in pregnancies complicated by preterm delivery (PTD). STUDY DESIGN: A cross-sectional study was conducted with 95 pregnant women followed to term and 25 who presented with PTD. Samples of AF from all patients were obtained during cesarean section and the PTX3 concentration was determined by enzyme immunoassay (ELISA). Maternal characteristics were compared by ANOVA and the Kruskal-Wallis and Chi square tests. Comparison between PTX3 concentrations in the "PTD in labor" and "PTD not in labor" groups were performed using the Mann-Whitney test. A p value <0.05 was considered statistically significant. RESULTS: Regarding term pregnancies, PTX3 concentrations were not statistically different across the period studied (37 weeks to 40 weeks). Among preterm pregnancies, those in preterm labor (PTL) presented higher PTX3 levels than those not in labor (p=0.001) and the risk of occurrence of PTL increased by 1% with a rise of 1pg/mL in PTX3. CONCLUSION: PTX3 is a physiological constituent of the AF, and its concentration is elevated in the presence of spontaneous PTL, reinforcing the theory that PTX3 plays a role in the innate immune response during gestational complications associated with infectious/inflammatory conditions.

Computer-assisted telephone interviewing (CATI): using the telephone for obtaining information on reproductive health.

The objective of this study was to evaluate the feasibility of using computer assisted telephone interviewing (CATI) as a method for obtaining information on reproductive health in Brazil. A total of 998 eligible women for the study were selected to answer a questionnaire through computer- assisted telephone interviewing undertaken by trained interviewers. The outcomes of each telephone contact attempt were described. Differences between groups were assessed using the χ(2) test. Phone contact was made in 60.3% of the attempts and 57.5% of the interviews were completed. The success rate improved with the decrease in time from hospitalization to interview and with the higher numbers of telephones available. A total of 2,170 calls were made, comprising of one to sixteen attempts per woman. The majority of situations where extra calls were necessary were due to the number being busy or to the fact that the woman was not available at the time of the call. CATI can prove be a valuable procedure for obtaining information on reproductive health among Brazilian women, particularly for relatively recent events and when more than one alternative telephone number is available.

O objetivo foi avaliar a facticidade do telefone como um método de obtenção de informações sobre saúde reprodutiva no Brasil (CATI). Um total de 998 mulheres elegíveis a um estudo foi selecionado para responder um questionário por telefone com o auxílio de computador e aplicado por entrevistadoras treinadas. Os resultados de cada tentativa de contato estão descritos. A diferença entre os grupos foi avaliada pelo teste qui-quadrado. O contato telefônico foi feito em 60,3 por cento e 57,5 por cento completaram a entrevista. A taxa de sucesso melhorou com a diminuição do tempo entre a hospitalização e a entrevista e com a quantidade de números de telefone disponível. Um total de 2.170 chamadas foi feito, de 1 a 16 tentativas por mulher. A maioria das chamadas adicionais foi em razão de a linha estar ocupada ou de a mulher não ter disponibilidade naquele momento. O CATI pode ser um procedimento útil para obtenção de informações em saúde reprodutiva entre mulheres brasileiras, especialmente se dirigido a eventos relativamente recentes e quando mais de um número alternativo de telefone está disponível.

A pilot clinical trial comparing an acid-buffering formulation (ACIDFORM gel) with metronidazole gel for the treatment of symptomatic bacterial vaginosis.

AIM: To compare the effectiveness of an acid-buffering formulation gel (ACIDFORM) with metronidazole gel in the treatment of symptomatic bacterial vaginosis (BV). METHODS: After a confirmed diagnosis of BV according to the criteria established by Nugent and Amsel, 30 nonpregnant women were enrolled in a randomized, double-blind clinical study. The women were randomly assigned to receive either 5 g ACIDFORM gel (n = 13) or 10% metronidazole gel (n = 17) intravaginally once daily for five consecutive days. Participants were evaluated in two follow-up visits (7-12 days and 28-35 days after treatment). Therapeutic success was defined as the presence of less than three of Amsel's criteria. If three or more criteria were present at first or second follow-up visit, the woman was excluded from the study and treated orally with metronidazole. Nugent scores were recorded at each visit but these were not used to define cure. RESULTS: At the first follow-up visit, 15 (88%) of the women in the metronidazole group were cured compared with only three (23%) in the ACIDFORM group (P < 0.001). The remaining 12 women (10 of the ACIDFORM group and two of the metronidazole group) were considered as failure and were treated orally with metronidazole. At the second follow-up visit, two of the ACIDFORM-treated women and six of the metronidazole-treated women presented recurrent BV. Four women in the ACIDFORM group and one in the metronidazole group reported occasional burning and itching during product use. CONCLUSION: ACIDFORM gel was significantly less effective than high-dose metronidazole gel for the treatment of symptomatic BV.

Follow-up of users of intrauterine device with and without bacterial vaginosis and other cervicovaginal infections.

This study aimed to assess the prevalence of bacterial vaginosis (BV) and other cervicovaginal infections, as well as the incidence of complications among new users of IUD, 1 and 6 months after its insertion, in the City of Campinas, Brazil. A total of 223 women who had a TCu-380A IUD inserted from May through November 2001, were included in the study. After the IUD insertion all women were scheduled to two additional visits: after 1 month and after 6 months, when they were interviewed and a pelvic examination was performed, along with a collection of specimens from the vagina and the endocervix for laboratory testing. The Nugent's criterion was used for the BV diagnosis. They were also evaluated with regard to presence of complications possibly related to IUD insertion and use, i.e., abnormal bleeding, dysmenorrhea, expulsion and pelvic inflammatory disease. The prevalence of cervicovaginal infections was 29.1%, BV being the most frequent (19.7%). Dysmenorrhea was more frequent among women with BV than among women without BV (p = 0.03). A trend of abnormal bleeding being more frequent among women with BV was also found. In conclusion, BV after 1 month of IUD insertion was not associated with IUD complications, with the exception of dysmenorrhea.

Complicações perinatais em gestantes com e sem vaginose bacteriana / Perinatal complications in pregnant women with and without bacterial vaginosis

Objetivos:comparar a freqüência de trabalho de parto prematuro (TPP), prematuridade, rotura prematura de membranas (RPM) e RN de baixo peso (< 2.500 g) em gestantes com Vaginose Bacteriana (VB). Verificar a validade da investigação rotineira de VB durante o pré-natal. Métodos:foram estudadas 217 mulheres com idade gestacional entre 28 e 32 semanas (35 com VB e 182 sem VB). O diagnóstico de VB foi realizado por meio dos critérios clínicos de Amsel. Os dados foram analisados através do teste de chi² , exato de Fisher, Mann-Whitney e Risco Relativo. Resultados:as incidências de TPP, prematuridade, RPM e baixo-peso ao nascimento foram maiores no grupo de gestantes com VB do que no grupo-controle (29,4 por cento vs 3,8 por cento; 28,6 por cento vs 3,3 por cento; 22,9 por cento vs 10,4 por cento; 20,0 por cento vs 3,3 por cento, respectivamente). As médias da idade gestacional e do peso ao nascer foram significativamente menores nos recém-nascidos das mães portadoras de VB (265,8 dias vs 279,9 dias; 2.958 g vs 3.294 g, respectivamente). Conclusões:todas as complicações perinatais estudadas estiveram significativamente associadas com a presença de VB não-tratada durante a gestação. Portanto, sugerimos que se deve incluir o diagnóstico e o tratamento adequados da VB na rotina de atendimento pré-natal nos serviços de obstetrícia, pois tal medida poderá ser efetiva na redução destas complicações perinatais.

Purpose:to compare the incidence of preterm labor and birth, premature rupture of membranes (PROM) and low birth-weight newborns (< 2,500 g) between two groups of pregnant women (with or without BV). To verify the adequacy of including a regular prenatal BV investigation. Methods:a total of 217 women between 28 and 32 weeks of pregnancy (35 with BV and 182 without BV) were studied. The diagnosis of BV was established according to Amsel's criteria. The data were analyzed by the chi² test, Fisher's test, Mann-Whitney test and the relative risk. Results:the incidence of preterm labor, preterm birth, PROM and low birth-weight was statistically higher in the group of women with BV than in the control group (29.4 percent vs. 3.8 percent; 28.6 percent vs. 3.3 percent; 22.9 percent vs. 10.4 percent; 20.0 percent vs. 3.3 percent; respectively). The means of gestational age and birth-weight were significantly lower in the newborns from mothers with BV (265.8 days vs. 279.9 days; 2,958 g vs. 3,294 g, respectively). Conclusion:all perinatal complications studied were significantly associated with the presence of untreated BV during pregnancy. Therefore, the diagnosis and adequate treatment should be included in the routine prenatal assistance at Brazilian Obstetrics Services. Such measure may be effective in the reduction of these perinatal complications.
