Book Description
Introducción: Los estudios sobre la odontogénesis han indicado que la posición, el número, el tamaño y la forma de los diferentes dientes están bajo control genético (1). El desarrollo de los dientes es un proceso complejo en el que participan multitud de genes, esto lleva a pensar que en las anomalías dentarias más de un gen defectuoso contribuye a una gran variabilidad clínica (2). A la ausencia congénita de algún diente se le denomina agenesia dental. Se puede definir como aquella situación en la cual uno o más dientes temporales o definitivos están ausentes, por falta de formación o del desarrollo de los gérmenes dentales, y existe ausencia clínica y radiológica de algún diente o germen dental a una edad que debería estar presente (1, 3-6). Los dientes supernumerarios se han definido como dientes que exceden de la fórmula dental normal, independientemente de su localización y forma (4, 7, 8). Objetivos: Estudiar las alteraciones del desarrollo dental que afectan al número de dientes y sus características de presentación, en la dentición permanente de una muestra de niños/as que acuden a recibir atención dental a la Facultad de Odontología de la Universidad Complutense de Madrid, y compararlas con un estudio previo de hace 26 años...

Book Description
Our hope is to enlighten and encourage those affected by aniridia and WAGR Syndrome by providing patient support and medical information. There is information to inform parents, teachers, doctors, employers, and the public about aniridia and what it is like to live with it. Several renowned doctors contribute medical chapters. Personal experiences from individuals with aniridia and parents with children with aniridia provide encouragement. Contact information for Aniridia Foundation International (AFI) is included. When a child is born without a complete iris, it is usually a symptom of a broader condition. Known as aniridia, this condition can also be a sign other parts of the eye are underdeveloped as well. Moreover, recent research shows that the gene involved can also affect the kidneys, pancreas and forebrain, so aniridia can coincide with a range of symptoms known as WAGR syndrome. Until recently, however, there was very little information available on aniridia and WAGR Syndrome. Even now, not all of the available information is current or correct, so that when a child is diagnosed with aniridia, the parents often find or are given information that is confusing and even frightening. We created this book to help those families see that they are not alone, and there are a lot of answers and a great deal of hope. It contains information about aniridia and WAGR Syndrome for parents, other family members, friends, teachers, doctors, and employers. We have been very fortunate to have several renowned doctors contribute current and comprehensive medical information that will help to provide concrete answers to basic questions and demystify these conditions. The book has many personal stories from individuals and parents that will help to give a more complete picture of what it is like to live with aniridia and WAGR Syndrome and provide encouragement and comfort. It also contains information about where to go for more answers and support, including the Aniridia Foundation International (AFI), http://www.aniridia.net, a non-profit organization created by one of the authors, Jill Nerby. We hope that you will read this book and join us in creating a better future for those with aniridia and WAGR Syndrome.

Book Description
It is with great pleasure that I write this Foreword to the Proceedings of the International Conference on Behçet’s Disease which was held in Berlin in June 2002. This was the first International Conference held under the auspices of the International Society for Behçet’s Disease which was founded in 2000 in Seoul. First, I congratulate our colleagues in Berlin, led by Professor Christos Zouboulis of the Department of Dermatology at the Free University of Berlin, for having organised a most successful conference and for having compiled these proceedings so rapidly. It will be realised immediately on scanning the contents of this book that the conference was truly international with 210 participants from 26 countries, as Professor Zouboulis has noted in his preface. These included basic scientists, epidemiologists, pathologists, clinicians and, importantly, representatives from patient organisations. The latter held their own conference alongside the scientific-medical conference to mutual benefit. The combined session of patients and doctors (abstracts on pp 601 – 626) gave the opportunity for an exchange of information and fruitful discussion. The wide ranging scope of the communications is evident from the index and it was most encouraging to see their origin – from all parts of the world, from senior and junior colleagues and, from many different disciplines. Many communications may be regarded as preliminary reports of research in progress and we look forward to seeing the definitive publications in appropriate journals in due course.

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.
