Effects of pregnancy and childbirth on the pelvic floor
Michel Naser,Valentín Manríquez,Mauricio Gómez
Medwave , 2012,
Abstract: The pelvic floor dysfunctions include urinary incontinence, pelvic organ prolapsed and anal incontinence. One in ten women will be subjected to surgery for pelvic floor dysfunction during their lifetime. In addition, between 30% and 50% will have a recurrence of these interventions. Motherhood is a factor that contributes significantly to the submission of pelvic dysfunctions. There is still no proven evidence that vaginal delivery is an absolutely crucial factor for the presence of pelvic floor dysfunction. There is extensive research on pregnancy and child birth and their effects on the pelvic floor and if some of the obstetric action scan be modified in order to protect it from potential damage.

Revista Chilena de Obstetricia y Ginecología , 2008,
Abstract: Objetivos: Describir una técnica quirúrgica, novedosa en el medio nacional, de abordaje vaginal, para el tratamiento del prolapso apical: la suspensión transvaginal alta a ligamentos úterosacros (STALUS). Método: Estudio descriptivo longitudinal, de 57 pacientes con defectos apicales, a los cuales se les realizó esa técnica entre Diciembre de 2002 y Octubre 2005. Se realizó estadística descriptiva y test t (2 muestras) para análisis de pronóstico anatómico (POP-Q). Para análisis de potenciales factores pronósticos se utilizó ANOVA, regresión lineal y logística. Resultados: El tiempo operatorio promedio fue de 151 minutos. El resultado anatómico (POP-Q), pre y postoperatorio, resultó favorable y estadísticamente significativo, en los nueve puntos evaluados, 49 de las 54 pacientes fueron seguidas en promedio durante 15 meses. En el compartimiento apical (punto C) obtuvimos curación del 89% y no hubo fracasos. En la pared anterior, 22% de las pacientes recidivaron. En cuanto a las complicaciones, se produjo una fístula ureterovaginal. Conclusiones: Tomando las precauciones necesarias, es una técnica segura y reproducible, con buenas tasa de curación. Asegurar la indemnidad del uréter, siempre será una obligación. La recidiva en pared anterior, aunque sea asintomática, resulta ser extremadamente alta, lo que nos obliga a pensar en nuevas técnicas de abordaje de este compartimiento. Objective: To describe a novel surgery technique in the national ground, of vaginal approach for the treat-ment of apical prolapse: the transvaginal high suspensión to the uterosacral ligaments (STALUS). Method: It is a longitudinal descriptive study that included 57 patients with apical support defects, in which this technique was performed between December 2002 and October 2005. Descriptive statistics and t test were per-formed for the anatomical outcome (POP-Q). For the potential prognosis factors, ANOVA, lineal regression and logistic, were used. Results: The average surgery time was 151 minutes. The anatomical result (POP-Q), before and after surgery, was favourable and significant in the nine points evaluated. 49 of 54 patients were followed for 15 months in average. In the apical compartment (C point) we got an 89% of cure and there were no failure. In the anterior wall, instead, 22% of our patients recurred. About complications, there was an ureterovaginal fistula. Conclusions: If all precautions are taking, there is a secure and reproducible technique, with good cure rate. To secure the uréter it is always an obligation. The recurrence in the anterior wall, even been asy
NEUROMODULACIóN EN PATOLOGíAS DE PISO PéLVICO

Revista Chilena de Obstetricia y Ginecología , 2010,
Abstract: A través de la historia la neuromodulación ha demostrado ser una alternativa de tratamiento eficaz en el manejo de diversas disfunciones del piso pélvico. Distintas técnicas intentan conseguir un objetivo común, sin embargo, el éxito terapéutico es disímil dependiendo de la severidad y tipo de patología. Describimos los aspectos clínicos y operacionales relacionados con las diversas técnicas, así como los mecanismos de acción propuestos para la neuromodulación. Through hystory, neuromodulation have proved to be an effective alternative of management of pelvic floor dysfunctions. Several technical alternatives try to reach a same therapeutic objetive, however, depending on the severity and type of symptom their succes differ. We describe the clinical and technical aspects related to those different technics so as the mechanisms of action that are propose for the neuromodulation.

Abstract: the section "special features" is dedicated to share with its readers thematic works about natural history, ecology and evolution. in this introduction we focus on the role that theories play in the construction of evolutionary thinking. first, we briefly show the importance of lamarck's work in the context of pre-darwinian theories about organic evolution. then, the main components of the darwinian theoretical core and its postdarwinian extensions are thoroughly discussed. finally the essays following this introduction in the present issue are summarized.
Emergence of Darwinian theories on evolution of Homo sapiens (Catarrhini: Hominidae) and their relevance for social sciences
MANRíQUEZ,GERMáN;
Revista chilena de historia natural , 2010, DOI: 10.4067/S0716-078X2010000400005
Abstract: despite the great impact that the darwinian theories on organic evolution have had in the development and consolidation of biology as an autonomous scientific discipline, their relevance in social sciences, and particularly in archaeology and anthropology still remain ambiguous. this ambiguity is reflected in the classical interpretation of darwin's work pervading social sciences during more than one century, according to which the same ideas that contributed to the understanding of natural processes from a scientific perspective would be at the basis of a misleading interpretation of the evolution of human societies due to the application of the principie of natural selection to the social processes. here we show how the works of t.h. huxley and a.r. wallace positively stimulated darwin to answer to the question about the origin of human populations considering culture from an evolutionary perspective as a factor opposed to the negative action of natural selection on human societies, thus refuting the classical interpretation of darwin's work made by social sciences. the role played by the biocultural approach in understanding human evolution as well as in promoting the integrative thinking in social sciences is also discussed.

Abstract: Despite the great impact that the Darwinian theories on organic evolution have had in the development and consolidation of biology as an autonomous scientific discipline, their relevance in social sciences, and particularly in archaeology and anthropology still remain ambiguous. This ambiguity is reflected in the classical interpretation of Darwin's work pervading Social Sciences during more than one century, according to which the same ideas that contributed to the understanding of natural processes from a scientific perspective would be at the basis of a misleading interpretation of the evolution of human societies due to the application of the principie of natural selection to the social processes. Here we show how the works of T.H. Huxley and A.R. Wallace positively stimulated Darwin to answer to the question about the origin of human populations considering culture from an evolutionary perspective as a factor opposed to the negative action of natural selection on human societies, thus refuting the classical interpretation of Darwin's work made by Social Sciences. The role played by the biocultural approach in understanding human evolution as well as in promoting the integrative thinking in Social Sciences is also discussed. A pesar del enorme impacto que las teorías de Darwin sobre la evolución orgánica han tenido en el desarrollo y la consolidación de la biología como disciplina científica autónoma, su pertinencia en ciencias sociales, y particularmente en arqueología y antropología sigue siendo ambigua. Esta ambigüedad se refleja en la interpretación clásica de la obra de Darwin que ha permanecido en las ciencias sociales durante más de un siglo, según la cual las mismas ideas que contribuyeron a la comprension de los procesos naturales desde una perspectiva científica estarían en la base de una interpretación errónea de la evolución de las sociedades humanas debido a la aplicación del principio de la selección natural a los procesos sociales. Se muestra cómo la obra de T.H. Huxley y AR. Wallace estimularon positivamente a Darwin para responder a la pregunta sobre el origen de las poblaciones humanas. Esta respuesta consideró a la cultura desde una perspectiva evolutiva y como un factor opuesto a la acción negativa de la selección natural en las sociedades humanas, rechazándose así la interpretación clásica de la obra de Darwin formulada desde las ciencias sociales. Se discute el rol que juega el enfoque biocultural en la comprension de la evolución humana así como en promover el pensamiento integrativo en las ciencias sociales.

Finally the essays following this introduction in the present issue are summarized. La sección "Temas especiales" está dedicada a compartir con sus lectores trabajos temáticos sobre historia natural, ecología y evolución. En esta introducción nos centraremos en el papel que juegan las teorías en la construcción del pensamiento evolutivo. En primer lugar, se mostrará brevemente la importancia de la obra de Lamarck en el contexto de las teorías predarwinianas sobre evolución orgánica. Luego se discutirán en detalle los principales componentes del núcleo teórico del darwinismo así como sus extensiones postdarwinianas. Finalmente se resumen los ensayos que siguen a la presente introducción.
