ABSTRACT

Current patterns of preventive antibiotic prescribing are encouraging the spread of antimicrobial resistance. Recently, the Spanish Society of Implants (SEI) developed the first clinical practice guidelines published to date, providing clear guidelines on how to prescribe responsible and informed preventive antibiotic therapy (PAT) based on the available scientific evidence on dental implant treatments (DIs). The present document aims to summarise and disseminate the recommendations established by this expert panel. These were based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Studies were analysed using the Scottish Intercollegiate Guidelines Network (SIGN) checklist templates and ranked according to their level of evidence. They were then assigned a level of recommendation using the Grading of Recommendations, Assessment, Development and Evaluation system (GRADE). Guidelines were established on the type of PAT, antibiotic and dosage of administration in the placement of DIs without anatomical constraints, in bone augmentation with the placement of DIs in one or two stages, placement of immediate DIs, sinus elevations, implant prosthetic phase, as well as recommendations in patients allergic to penicillin. Therefore, the PAT must be adapted to the type of implant procedure to be performed.

ABSTRACT

OBJECTIVES: To create reference charts for fetal age assessment based on fetal sonographic biometry in a population of pregnant women living in the third largest city in Colombia and compare them with charts included in ultrasound machines. METHODS: The study data were obtained from women with a single pregnancy and confirmed gestational age between 12 and 40 completed weeks. All women were recruited specifically for the study, and every fetus was measured only once for biparietal diameter, head circumference, abdominal circumference, and femur length. Polynomial regression models for gestational age as a function of each fetal measurement were fitted to estimate the mean and standard deviation. Percentile curves of gestational age were constructed for each fetal measurement using these regression models. RESULTS: Biparietal diameter, head circumference, abdominal circumference, and femur length were measured in 792 fetuses. Tables and charts of gestational age were derived for each fetal parameter. A cubic polynomial model was the best-fitted regression model to describe the relationships between gestational age and each fetal measurement. The standard deviation was estimated by simple linear regression as a function of each fetal measurement. Comparison of our gestational age mean z scores with those calculated by reference equations showed statistically significant differences (P < .01). CONCLUSIONS: We present a set of reference charts, tables, and formulas for fetal age assessment based on fetal sonographic biometry. The results support the recommendation that these charts and tables could be more appropriate for assessing fetal age in Colombian populations than those currently included in the software of ultrasound machines.

ABSTRACT

OBJECTIVES: To create reference charts for fetal sonographic biometric measurements in a population of pregnant women living in the third largest city in Colombia and compare them with charts included in ultrasound machines. METHODS: The data were obtained from women with a single pregnancy and confirmed gestational (menstrual) age between 12 and 40 weeks. All women were recruited specifically for the study, and every fetus was measured only once for biparietal diameter, head circumference, abdominal circumference, and femur length. Raw data for each fetal measurement were modeled by fitting regression models separately to estimate the mean and standard deviation as a function of gestational age. Percentile curves were constructed for each measurement by gestational age using these two regression models. We compared our mean z scores with those expected by reference equations. RESULTS: Measurements were obtained for 792 fetuses. A cubic polynomial model was the best-fitted regression model to describe the relationships between each fetal measurement and gestational age. The standard deviation for each measurement was estimated by simple linear regression as a function of gestational age. Comparison of our mean z scores with those by reference equations showed significant differences in some fetal measurements (P < .01). CONCLUSIONS: We present a set of reference percentile charts, tables, and formulas for fetal biometric measurements from a Colombian population. We believe that our fetal charts could be used nationwide in Colombia; nevertheless, a national sample will contribute to their validation and promotion of the development of Colombian fetal size charts.

ABSTRACT

OBJECTIVE: To establish whether the degree of clinician bias in fundal height measurement is affected by patient body mass index (BMI) or provider experience. METHODS: Singleton, ultrasound-dated pregnancies between 24 weeks and 40 weeks underwent fundal height measurements (n=103) by two providers, each using one blank and one marked measuring tape. Outcomes were the differences between the blank and marked measurements (bias) and between fundal height and gestational age for blank and marked tapes. Mixed models for repeated measures (provider and tape type) were used to estimate outcomes and compare them according to provider experience level and for patient background and anthropometric characteristics. RESULTS: Bias increased with patient BMI, although only among providers with less than 2 years of experience (juniors, P=.004) and not for those with more experience (seniors, P=.38). Similarly, bias decreased over the study enrollment period among junior, but not senior providers. Providers of all levels were more likely to measure a fundal height within 3 cm of gestational age using a marked tape than a blank tape (odds ratio 1.83, 95% confidence interval 1.41-2.38). CONCLUSION: Clinicians are biased in their fundal height measurements by knowledge of gestational age and use of a marked measuring tape. This tendency increases with higher patient BMI and with less provider experience.

ABSTRACT

BACKGROUND: Inappropriate activation of the renin-angiotensin system may play a part in the development of preeclampsia. An insertion/deletion polymorphism within the angiotensin-I converting enzyme gene (ACE-I/D) has shown to be reliably associated with differences in angiotensin-converting enzyme (ACE) activity. However, previous studies of the ACE-I/D variant and preeclampsia have been individually underpowered to detect plausible genotypic risks. METHODS AND FINDINGS: A prospective case-control study was conducted in 1,711 unrelated young pregnant women (665 preeclamptic and 1,046 healthy pregnant controls) recruited from five Colombian cities. Maternal blood was obtained to genotype for the ACE-I/D polymorphism. Crude and adjusted odds ratio (OR) and 95% confidence interval (CI) using logistic regression models were obtained to evaluate the strength of the association between ACE-I/D variant and preeclampsia risk. A meta-analysis was then undertaken of all published studies to February 2006 evaluating the ACE-I/D variant in preeclampsia. An additive model (per-D-allele) revealed a null association between the ACE-I/D variant and preeclampsia risk (crude OR = 0.95 [95% CI, 0.81-1.10]) in the new case-control study. Similar results were obtained after adjusting for confounders (adjusted per-allele OR = 0.90 [95% CI, 0.77-1.06]) and using other genetic models of inheritance. A meta-analysis (2,596 cases and 3,828 controls from 22 studies) showed a per-allele OR of 1.26 (95% CI, 1.07-1.49). An analysis stratified by study size showed an attenuated OR toward the null as study size increased. CONCLUSIONS: It is highly likely that the observed small nominal increase in risk of preeclampsia associated with the ACE D-allele is due to small-study bias, similar to that observed in cardiovascular disease. Reliable assessment of the origins of preeclampsia using a genetic approach may require the establishment of a collaborating consortium to generate a dataset of adequate size.

ABSTRACT

Polymorphisms in the endothelial NO synthase (eNOS) gene have been evaluated as risk factors for preeclampsia. However, data from small studies are conflicting. We assessed whether eNOS genotypes alter the risk of preeclampsia in a population in which the incidence of this disorder is high. A total of 844 young pregnant women (322 preeclamptic and 522 controls) were recruited from 5 cities. Genotyping for the Glu298Asp, intron-4 and -786T-->C polymorphisms in the eNOS gene was conducted. Multivariate odds ratios (ORs) were obtained to estimate the association of individual polymorphisms and haplotypes with preeclampsia risk. No increase in the risk of preeclampsia for the intron-4 or -786T-->C polymorphisms was observed under any model of inheritance. In contrast, in women homozygous for the Asp298 allele, the adjusted OR for preeclampsia was 4.60 (95% confidence interval [CI], 1.73 to 12.22) compared with carriers of the Glu298 allele. After a multivariate analysis, carriage of the "Asp298-786C-4b" haplotype was also associated with increased risk of preeclampsia (OR, 2.11 [95% CI, 1.33 to 3.34]) compared with carriers of the "Glu298-786T-4b" haplotype. The eNOS Glu298Asp polymorphism and the Asp298-786C-4b haplotype are risk factors for preeclampsia.

ABSTRACT

This prospective, multicenter study was conducted to evaluate the contraceptive reliability, cycle control and tolerability of a 21-day oral contraceptive regimen containing 20 microg ethinylestradiol and 75 microg gestodene in four Latin American countries (Mexico, Argentina, Brazil and Colombia). Participants took trial medication daily for 21 days. Contraceptive efficacy, cycle control and tolerability were evaluated over a period of 13 cycles. Efficacy data gathered from 5,109 treatment cycles were obtained from 393 participants. The trial medication proved to be an effective contraceptive and provided good cycle control. One pregnancy because of poor compliance was recorded. This resulted in a study Pearl index of 0.25. Forty-six percent of Latin American women reported one intracyclic spotting bleeding episode and 37.6% reported one intracyclic breakthrough bleeding (medium/excessive bleeding) episode during cycles 2-4 (primary target). Overall, intracyclic bleeding was reported in 41%. Overall, there was a trend towards a lower incidence of spotting in all the countries and this difference had statistical significance between Argentina and the others three countries (p < 0.05) during cycles 2-4. This trend was also apparent with respect to breakthrough bleeding, but again the difference did not achieve statistical significance. The discontinuation rate because of adverse events was low (3%); no serious adverse events were reported. More than 78% of the women in the four countries maintained constant body weight or lost weight (2 kg) during the study. The treatment effect on blood pressure was negligible. There were no appreciable changes in mean laboratory values over the course of the study.

ABSTRACT

La medicina basada en la evidencia ha demostrado mediante una serie de estudios, la eficacia clínica de algunos fármacos, como el caso del misoprostol análogo de la prostaglandina E1 utilizado en obstetricia para lograr maduración cervical en inducción de trabajo de parto con cérvix no favorable, con un efecto no deseado en la mayoría de los casos como lo es la hiperestimulación uterina. Se diseñó un estudio clínico prospectivo entre noviembre, 2002 y febrero, 2003 en la Clínica Rafael Uribe Uribe del Instituto de Seguro Social, Cali, donde se incluyeron 29 pacientes con criterio para inducción del trabajo de parto con índice de Bishop no favorable; se les administró 50 mcg de misoprostol por vía vaginal y desarrollaron polisistolia (>5 contracciones en 10 minutos). A estas 29 pacientes se les suministró 20 mg de nifedipina por vía oral en el momento en que apareció la polisistolia y se estableció mediante el registro por monitoría electrónica maternofetal durante 30 minutos la disminución en el número, la duración de las contracciones y la “actividad uterina”

ABSTRACT

Investigar las alteraciones vasculares en placentas de pacientes eclámpticas. Estudio descriptivo, 10 embarazadas normales y 10 eclámpticas, atendidas en el Servicio de Partos, Hospital Universitario del Valle, Cali, Colombia. Se realizó estudio histológico de la placenta, utilizando microscopía de luz, microscopía electrónica de barrido y microscopía electrónica de transmisión. Hallazgo característico en las pacientes eclámpticas es la presencia de necrosis fibrinoide y el depósito de material amorfo intramural, así como la disminución o estenosis del calibre de los vasos sanguíneos por engrosamiento de la capa media. Con microscopía de transmisión se observó marcado daño en el citoplasma, con presencia de vacuolas lipídicas y alteración en las organelas principalmente en el retículo endoplásmico rugoso. Lo anterior podría contribuir a explicar el disbalance en los productos endoteliales vasomotores (aumento de tromboxano, endotelina, angiotensina y disminución de prostaciclina y óxido nítrico) que se manifiesta clínicamente como preeclampsia

ABSTRACT

Se presentan resultados de 174 mujeres adolescentes, usuarias de primera vez del Norplant. Se encontró que la edad promedio fue de 17.7 años; 39.9 por ciento eran nulíparas. La tasa acumulada de emabarazos a 2 años fue de 0 por ciento. El 48 por ciento tuvieron ciclos irregulares( 9 por ciento manchando, 20 por ciento sangrando y 19 por ciento amenorrea). Otros efectos adversos reportados fueron: mareos (6 por ciento), cefalea (4 por ciento) y aumento de peso (4 por ciento). La tasa de retiro fue de 6.8 por ciento. Las restantes usuarias están satisfechas con el método. Los anteriores datos nos permiten sugerir el uso del Norplant como método contraceptivo en este etario. Sin embargo, un estudio prolongado (5 años), es necesario para corroborar estos hallazgos

ABSTRACT

Objetivo: Evaluar la predicción de hipertensión gestacional y preeclampsia mediante la relación calcio/creatinina, hematocrito, recuento de palquetas y concentraciones séricas de ácido úrico, proteínas y calcio. Materiales y Metodos: Una cohorte de 445 mujeresemabarazadas nulíparas fueron seguidas prospectivamente desde la semana 20 de gestación hasta el parto. Los exámenes de laboratorio fueron realizados a la semana 20, 27 y 31. Se elaboró una curva ROC para cada prueba de laboratorio y posteriormente se compararon. Adicionalmente se calculó sensibilidad, especifidad y valores predictivos positivo y negativo para hipertensión gestacional y preeclampsia. Resultados: Todos los exámenes de laboratorio tuvieron bajs sensibilidades para hipertensión gestacional y preeclampsia (27 por ciento-68 por ciento). Las especificidades fueron moderadas (43 por ciento-83 por ciento) mientras los valores predictivos positivos fueron bajos (2 por ciento- 16 por ciento). Todas las curvas ROC fueron consideradas "inútiles" para predecir los trastornos hipertensivos del embarazo. Conclusión: La relación calcio/creatinina, hematocrito, recuento de las plaquetas y las concentraciones séricas de ácido úrico, proteínas y calcio total mostraron bajos valores predictivos para hipertensión gestacional y preeclampsia

ABSTRACT

Objetivo: Determinar si el magnesio cruza la barrera hematoencefálica en pacientes con preeclampsia. Material y Métodos: Se seleccionaron 41 embarazadas, 20 con preeclampsia(grupo de estudio) y 21 sin preeclampsia (grupo control). El grupo con preeclampsia recibió sulfato de magnesio en bolo inicial de 4 gr vía intravenosa y 1 gr/hora en dosis de mantenimiento. El grupo control no recibió sulfato de magnesio. A todas las pacientes se les practicó operación de cesárea(por indicación obstétrica) y se les recolectó 1 cm3 de líquido cefalorraquídeo en el momento de la punción espinal para la anestesia regional. Se mostraron además muestras de sangre periférica basal y 2 horas después. En todas las muestras se midió concentración de magnesio. Lo cual se hizo de menera ciega por uno de los investigadores. Resultados: Los niveles de magnesio en líquido cefalorraquídeo no fueron significativamente diferentes entre los dos grupos 4.88 mEq/L (grupo control) y 5.58 mEq/L (grupo estudio) (p=0.29). En contraste, los niveles séricos de magnesio fueron significativamente más altos en el grupo con preeclampsia(5.91 mEq/L) que en el grupo control (4.27 mEq/L) (p menor 0.003). Conclusiones: La barrera hematoencefálica parece no ser permeable al paso del ión magnesio en la preeclampsia

ABSTRACT

Objetivo: Comparar la acción útero inhibitoria de la Nifedipina(calcio-bloqueador) con la Terbutalina (estimulante beta-andronérgico).Material y métodos: Se consideraron elegibles todas las mujeres embarazadas entre la semana 26 y 35, actividad uterina aumentada, gestación única, membranas íntegras y cambios cervicales. El estudio se hizo prospectivo y randomizado, dividiendo las pacientes en dos grupos: Uno recibió Nifedipina vía oral en dosis de 20 mgr, seguido de 10 mg cada 4 horas por 24 horas. Posteriormente 10 mg cada 8 horas durante una semana. El grupo terbutalina recibió 5 mg intravenosos por 12 horas seguidos de 2.5 mg cada 8 horas vía oral durante una semana. Hasta hoy han ingresado al estudio 46 pacientes. Resultados: Ambos fármacos han mostrado buena eficacia útero inhibitoria con pocos efectos colaterales. El promedio de prolongación del embarazo desde el inicio de la terapia fue de 27-/10 días con Nifedipina y de 15-/5 días con Terbutalina(p-0.05). Como efecto secundario, ambos fármacos produjeron taquicardia materna y cefalea. Con Nifedipina se presentó además en la mayoría de los pacientes hipotensión arterial entre 10 y 15 mmHg. Conclusión: La Nifedipina es una agente tocolítico comparable a la Terbutalina. Por causar una mayor prolongación en el embarazo, lo aconsejamos como una buena alternativa en el manejo del trabajo de parto pretérmino

ABSTRACT

Se presentan resultados de 68 embarazadas con Ruptura Prematura de Membranas de Pretérmino(R.P.M.P.) sin infección ni trabajo de parto. La mitad (n-34) evolucionó espontáneamente(grupo control).La otra mitad (grupo experimental), recibió a su ingreso esteroides (betametasona) más betamiméticos (terbutalina y fenoterol). La edad gestacional, paridad, peso neonatal, puntaje de Apgar, infección puerperal y neonatal, mortalidad neonatal fue similar en ambos grupos. La incidencia de Síndrome de Dificultad Respiratoria (S.D.R.) en el grupo control fue de 70.5 por ciento. En el grupo experimental de 32.3 por ciento (chi cuadrado-10.43; p menor 0.01). Los datos anteriores sugieren que en un manejo con esteroides y betamiméticos puede ser empleado selectivamente en R.P.M.P. en mujeres de bajo nivel socio- económico

ABSTRACT

La hipertension arterial inducida por el embarazo (HIE) es una causa importante de morbi-mortalidad materna y perinatal en la poblacion colombiana. En el presente trabajo se evaluo la eficiencia de la prueba de presion supina(PPS) o (roll over test, ROT) para predecir el desarrollo posterior de HIE en una poblacion obstetrica residente en un area marginada de la ciudad de Cali. Se practico en 127 embarazadas entre 28 y 32 semanas de amenorrea sin patologia ni antecedentes importantes demostrables en el momento de su consulta. Despues del embarazo se revisaron las historias clinicas de cada una de las pacientes para establecer cuales de ellas habian desarrollado toxemias en el transcurso de la gestacion. De 127 embarazadas estudiadas, 25 tuvieron PPS positiva, y 15 hicieron posteriormente HIE. De las 102 embarazadas con PPS negativa, 93 no desarrollaron HIE. Al determinar la eficiencia de la PPS en esta poblacion marginada, se encontraron los siguientes valores: sensibilidad, de 62.5%; especificidad, 90.3%; valor predictivo de la prueba positiva, 60% y valor predictivo de la prueba negativa, 91.2%. Se concluye que la PPS se debe efectuar de rutina en el control prenatal de todas las mujeres embarazadas entre las 28 y 32 semanas de gestacion, porque es un metodo seguro, facil de realizar, y sin costo, que requiere solamente medir la tension arterial y un periodo corto para su ejecucion

ABSTRACT

Durante muchos anos y en diferentes publicaciones cientificas se presentan tablas de estudios que analizan los danos al embrion o feto cuando la madre es irradiada en las primeras semanas de embarazo y aun durante toda la gestacion, como es el caso de las madres ocupacionalmente expuestas a las radiaciones. Pero estas publicaciones no dan al ginecologo una idea clara de como la irradiacion dana las celulas del feto y que determina el alto riesgo a la irradiacion. Debido a la alta concentracion de energia que transporta la radiacion ionizante, de cualquier tipo, en especial la radiacion gama y los rayos X, de amplio uso en medicina, los centros vitales de las celulas estan en proceso de mitosis, que es el caso del feto en las primeras semanas de embarazo. Se presenta en este trabajo una descripcion completa del agente danino, "LA RADIACION IONIZANTE", la manera que ella interactua con las celulas y los factoresd que determinan la alta radiosensibilidad del feto
