ABSTRACT

Resumen: ANTECEDENTES: la inducción del trabajo de parto es un procedimiento que se indica cuando existe riesgo de continuar el embarazo, en lugar de interrumpirlo. Esta maniobra enfrenta nuevas presiones, por lo que es necesario mantener actualizado el conocimiento sobre su indicación. En los últimos años se han desarrollado protocolos clínicos de mayor eficacia y seguridad, que han hecho más accesible este procedimiento. OBJETIVO: emitir un consenso actualizado y analizar los diferentes aspectos de la práctica cotidiana relacionada con la inducción del trabajo de parto. MATERIALES Y MÉTODOS: se integró un grupo de especialistas de trece instituciones nacionales para analizar diferentes aspectos de la práctica cotidiana de la inducción del trabajo de parto. Se siguió una metodología tipo Delphi de cuatro etapas, con bibliografía de normas clínicas internacionales de apoyo. CONCLUSIONES: la inducción del trabajo de parto considera los siguientes criterios: establecer con certeza que el procedimiento ofrece el mejor desenlace para la madre y el feto, confirmar la edad gestacional, realizar la evaluación obstétrica completa y contar con infraestructura para enfrentar las posibles complicaciones. Existen diferentes opciones para la inducción del trabajo de parto; sin embargo, en los últimos años se ha generalizado la prescripción de análogos de prostaglandinas (misoprostol) en todo el mundo. El especialista debe efectuar la evaluación individualizada de la paciente y el feto, con la finalidad de descartar situaciones que comprometan la salud de ambos. La complicación más común de la inducción del trabajo de parto es la taquisistolia, que puede asociarse con desprendimiento prematuro de placenta, rotura uterina y sufrimiento fetal agudo. Los óvulos vaginales de liberación controlada representan la única opción para retirar el estímulo con dinoprostona o misoprostol ante efectos adversos.


Abstract: BACKGROUND: Induction of labor is a maneuver indicated when there is a greater risk of continuing the pregnancy, than interrupting it. The induction of labor faces new pressures that make it necessary for the doctor to be permanently updated. In recent years, clinical protocols of greater efficiency and safety have been developed, which have made this procedure more accessible. OBJECTIVE: To present an updated consensus and to analyze the different aspects related to the labor induction. MATERIAL AND METHODS: A Delphi-type of consensus was conducted with participation of active obstetricians and gynecologists specialists from thirteen national institutions. Major clinical-oriented topics of induction of labor were addressed. CONCLUSIONS: To induce labor, it is necessary that at least the following situations coexist: to establish with certainty that the procedure offers the best outcome for the mother and her child, to confirm the gestational age, to make a complete obstetric evaluation and to have the infrastructure Necessary to deal with possible complications. There are several options to induce labor, although in recent years the indication of prostaglandin analogues (misoprostol) has become the most common option worldwide. The specialist must make an individualized evaluation of the patient and the fetus, in order to rule out situations that may endanger the health of any of them. The most common complication of labor induction is tachysystole, which can be complicated by premature placental abruption, uterine rupture and acute fetal distress, requiring urgent attention. Controlled-release vaginal ovules are the only option available to withdraw the stimulus with dinoprostone or misoprostol in the presence of adverse effects.

ABSTRACT

ABSTRACT: This study aimed to evaluate and compare the effects of the fixed combination of dorzolamide/timolol with those of tafluprost on intraocular pressure (IOP) and pupil diameter (PD) in healthy dogs (n=10). Two experiments were conducted with an interval of 30 days. In both, IOP and PD were assessed at 8, 11, 14, 17, and 20h. Parameters were evaluated during baseline, treatment period of four days, and one day of post-treatment. During treatment phase, IOP decreased by 0.74 (P<0.05), 1.88 (P<0.01), 2.94 (P<0.001), and 3.10mmHg (P<0.01), in dorzolamide/timolol-treated eyes; and by 1.50, 2.18, 2.14, and 2.18mmHg (P<0.001), in tafluprost-treated eyes. PD decreased by 0.24 (P<0.01), 0.32 (P<0.01), 0.49 (P<0.001), and 0.40mm (P<0.001), in dorzolamide/timolol treated eyes; and by 2.31, 2.55, 2.43, and 2.70mm (P<0.001), in tafluprost-treated eyes. Dorzolamide/timolol and tafluprost were able to decrease IOP and PD in healthy dogs. However, a cumulative effect of the fixed combination of dorzolamide/timolol was more effective in reducing IOP, than tafluprost. Comparisons between treatments showed that tafluprost was more effective in reducing PD throughout the treatment phase.


RESUMO: O estudo objetivou avaliar e comparar os efeitos da combinação fixa da dorzolamida/timolol com os da tafluprosta sobre a pressão intraocular (PIO) e o diâmetro pupilar (DP) em cães saudáveis (n=10). Dois experimentos com intervalo de 30 dias foram conduzidos. Em ambos, a PIO e o DP foram avaliados às 8, 11, 14, 17 e às 20h. Os parâmetros foram avaliados durante a fases basal, um período de tratamento de quatro dias, e um dia de pós-tratamento. Durante a fase de tratamento, a PIO dos olhos tratados com dorzolamida/timolol reduziram em 0.74 (P<0.05), 1.88 (P<0.01), 2.94 (P<0.001), e 3.10mmHg (P<0.01); e dos olhos tratados com tafluprosta em 1.50, 2.18, 2.14 e 2.18mmHg (P<0.001). O DP dos olhos tratados com dorzolamida/timolol reduziram em 0.24 (P<0.01), 0.32 (P<0.01), 0.49 (P<0.001) e 0.40mm (P<0.001); e dos olhos tratados com tafluprosta em 2.31, 2.55, 2.43 e 2.70mm (P<0.001). A dorzolamida/timol e a tafluprosta foram capazes de reduzir a PIO e o DP em cães saudáveis. Porém, efeito cumulativo do tratamento com dorzolamida/timolol foi observado, decorridos três dias de tratamento. Por essa razão, a dorzolamida/timolol foi mais efetiva que a tafluprosta na redução da PIO. Comparações entre os tratamentos demonstraram que a tafluprosta foi mais efetiva em reduzir o DP, durante toda a fase de tratamento.

ABSTRACT

PURPOSE: To compare the frequency of conjunctival HLA-DR expression (a surrogate marker for inflammation) in eyes treated with topical prostaglandin analogues versus eyes treated with other topical antiglaucomatous drugs. METHODS: Patients diagnosed with primary open-angle glaucoma presenting indication for trabeculectomy were divided in groups according to the use or not of prostaglandin analogues. All subjects were treated with the maximum tolerated dose of antiglaucomatous drugs until the date of the surgery. At the beginning of the surgical procedure, a 5 x 5 mm biopsy of the bulbar conjunctiva was collected, incubated with monoclonal anti-HLA-DR antibody and processed for histological analysis. RESULTS: Of the 31 eyes included (31 patients), 25 were under topical prostaglandin analogues (Group 1) and six under other topical pharmacological agents (Group 2). Fourteen eyes of Group 1 (56%) and three of Group 2 (50 %) were positive for the inflammatory marker HLA-DR (P=1.0). The percentage of stained cells ranged from 15.49 to 48.09% (median: 27.61) in Group 1, and from 18.35 to 28 (median: 20.71) in Group 2, with no differences statistically significant (p=0.33). CONCLUSION: The use of prostaglandin analogues did not increase conjunctival expression of HLA-DR compared to other topical antiglaucomatous agents.


OBJETIVO: Comparar a frequência da expressão conjuntival de HLA-DR (marcador inflamatório) em olhos tratados com análogos de prostaglandinas de uso tópico com a frequência em olhos tratados com outros medicamentos. MÉTODOS: Pacientes com glaucoma primário de ângulo aberto apresentando indicação de trabeculectomia foram agrupados segundo o uso ou não de análogos de prostaglandinas. Todos os participantes foram tratados com medicação máxima tolerada até o momento da cirurgia. Ao início do procedimento cirúrgico, uma biópsia de 5 x 5 mm da conjuntiva bulbar foi coletada, incubada com anticorpo monoclonal anti-HLA-DR e processada para análise histológica RESULTADOS: Dentre os 31 olhos incluídos (31 pacientes), 25 estavam em uso de análogos de prostaglandinas (Grupo 1) e seis em uso de outros agentes antiglaucomatosos (Grupo 2). Quatorze olhos do Grupo 1 (56%) e três do Grupo 2 (50%) apresentaram positividade para o marcador HLA-DR (p=1,0). A porcentagem de células coradas variou de 15,49 a 48,09% (mediana: 27,61%) no Grupo 1 e de 18,35 a 28% (mediana: 20,71%) no Grupo 2, com diferenças não estatisticamente significativas (p=0,33). CONCLUSÃO: O uso de análogos de prostaglandinas não aumenta a expressão conjuntival de HLA-DR comparado com outros medicamentos tópicos para o tratamento de glaucoma.
