Book Description
El síndrome de Down va a ser la discapacidad y alteración genética más común , cuenta con una prevalencia mundial de aproximadamente: 10/10.000 nacidos, dicha prevalencia en España 1/1.600. Dicho Síndrome ha sido muy investigado por diversos autores que generalmente han empleado como método de estudio la ortopantomografía o la telerradiografía y el análisis cefalométrico y, la gran mayoría se centra a nivel óseo para determinar las diferencias craneofaciales y el perfil esquelético. Sin embargo, a nivel dentario hay pocos estudios, es por eso por lo que se ha decidido realizar este estudio comparativo, para poder ver el comportamiento de los dientes y así en el futuro intentar establecer algunos valores cefalométricos para este tipo de pacientes....

Book Description
Se ha realizado un estudio con el objetivo de evaluar los resultados del aparato Bloques Gemelos en una muestra de 70 pacientes con maloclusión esquelética de Clase II y compararlos con una muestra maloclusiva de Clase II de similares características de 50 pacientes sin tratar, valorando de este modo sus ventajas e inconvenientes de cara a su aplicación clínica. El tiempo medio de tratamiento fue de 1,4 años y el período de observación en el grupo control, de 1,5 años. Tanto a los pacientes tratados con Bloques Gemelos como a los del grupo control se les realizó telerradiografía lateral de cráneo antes y después del período de tratamiento o de observación, para su trazado cefalométrico y poder comparar los cambios producidos. Se seleccionaron mediciones lineales y angulares de los análisis cefalométricos de Steiner, Ricketts, McNamara y Pancherz y se agruparon en distintos campos: Campo Esquelético Maxilar, con 6 parámetros: Campo Esquelético Mandibular, con 9 parámetros; Relación Esquelética Máxilo-Mandibular, 3 parámetros; Campo Esquelético Vertial, 12 parámetros y Campo Dentario, con 24 parámetros. Los resultados obtenidos en el grupo control apreciaron un incremento en el crecimiento maxilar, que conllevó un empeoramiento de la maloclusión de Clase II. En el grupo tratado con Bloques Gemelos se apreció una mejoría de la maloclusión de Clase II por acciones esqueléticas y dentarias, tanto del maxilar supeior como de la mandíbula. En la comparación entre ambos grupos, el grupo tratado con Bloques Gemelos experimentó una moderada inhibición del crecimiento del maxilar superior y un mayor crecimiento de la mandíbula resultando una notable mejoría de la relación máxilo-mandibular, con respecto al grupo control. Los cambios dentarios experimentales en el grupo tratado con Bloque Gemelos, observaron una importante corrección del resalte y de la sobremordida incisiva, así como mayor linguoversión de incisivos inferiores y mayor extrusión y mesialización del molar inferior, frente al grupo control.

Book Description
This widely acclaimed reference work gives a comprehensive survey of all significant human malformations and related anomalies from the perspective of the clinician. The anomalies are organized by anatomical system and presented in a consistent manner, including details of the clinical presentation, epidemiology, embryology, treatment and prevention for each anomaly. When known, the molecular or other pathogenetic basis for the malformation is given. Most anomalies are illustrated by photographs or drawings. Specific malformations are linked to syndromes through the extensive use of differential diagnosis tables. Over a decade has passed since the first edition of this book was published, and the revised edition fully incorporates the advances made in the field during the intervening years.. It reflects new understanding of human developmental biology that has emerged from molecular, cytogenetic, and biochemical studies; new observations by clinicians as well as enhanced diagnostic and prevention capacities; and more accurate and comprehensive epidemiology. By condensing much of the information presented in the first volume of the previous edition, and exercising rigorous editorial control, Drs. Stevenson and Hall and their contributors have managed to update the book while reducing its size to that of a single volume. All clinicians and scientists interested in birth defects, including pediatricians, geneticists, genetic counselors, obstetricians, and pediatric pathologists, will find this book to be an invaluable source of information.

Book Description
Owing to their unique state of preservation, mummies provide us with significant historical and scientific knowledge of humankind’s past. This handbook, written by prominent international experts in mummy studies, offers readers a comprehensive guide to new understandings of the field’s most recent trends and developments. It provides invaluable information on the health states and pathologies of historic populations and civilizations, as well as their socio-cultural and religious characteristics. Addressing the developments in mummy studies that have taken place over the past two decades – which have been neglected for as long a time – the authors excavate the ground-breaking research that has transformed scientific and cultural knowledge of our ancient predecessors. The handbook investigates the many new biotechnological tools that are routinely applied in mummy studies, ranging from morphological inspection and endoscopy to minimally invasive radiological techniques that are used to assess states of preservation. It also looks at the paleoparasitological and pathological approaches that have been employed to reconstruct the lifestyles and pathologic conditions of ancient populations, and considers the techniques that have been applied to enhance biomedical knowledge, such as craniofacial reconstruction, chemical analysis, stable isotope analysis and ancient DNA analysis. This interdisciplinary handbook will appeal to academics in historical, anthropological, archaeological and biological sciences, and will serve as an indispensable companion to researchers and students interested in worldwide mummy studies.
