uberraschende Heilerfolge und schwere Schadigungen, das sind die beiden Extreme in der Wirkungsweise der Rontgenstrahlen. In allen geeigneten Fallen Heilung zu erzielen, die nicht geeigneten Falle rechtzeitig von der Rontgenbehandlung auszuschliessen, und in jedem Falle eine Schadigung mit Sicherheit zu vermeiden, das ist die Forderung, deren Erfullung mit den Fortschritten in der Technik und in unserer Erkenntnis uber die Wirkungsweise der Strahlen jetzt nahe geruckt ist. Auf vielen Gebieten bringt die medizinische Literatur stets neue Erfolge der Rontgentherapie - die Chirurgie, Gynakologie, Neurologie, innere Medizin und die Dermatologie wetteifern in der Ausnutzung des neuen Heilmittels. Ein klarer Einblick und eigene Erfahrung des Einzelnen auf allen diesen Gebieten sind zur Zeit kaum mehr moglich. Eine genaue Kenntnis der einzelnen Krankheiten und ihres Verlaufes bei Anwendung aller ubrigen Heilmethoden ist erforderlich, um be urteilen zu konnen, in welchen Fallen die Rontgentherapie einen Fortschritt bedeutet. Die Haut ist dasjenige Organ, auf welches bei allen therapeuti schen Bestrahlungen unter allen Umstanden Rucksicht genommen werden muss und deshalb ist die Kenntnis von dem Verhalten der Haut gegen Rontgenstrahlen nicht nur fur den Dermatologen, sondern auch fur die ubrigen Disziplinen von Wichtigkeit. So durfte diese Arbeit, die fur Dermatologen bestimmt ist, in ihrem allgemeinen therapeutischen Teil vielleicht einen weiteren Kreis interessieren. Es ist selbstverstandlich, dass ich mich auf alle mir zugangigen Arbeiten anderer Autoren gestutzt habe; wenn trotzdem in dieser Arbeit alle Literaturangaben fehlen, so ist dies aus dem Grunde ge- IV Vorwort."

The study of the biology of tumours has grown to become markedly interdisciplinary, involving chemists, statisticians, epidemiologists, mathematicians, bioinformaticians, and computer scientists alongside biologists, geneticists, and clinicians. The Oxford Textbook of Cancer Biology brings together the most up-to-date developments from different branches of research into one coherent volume, providing a comprehensive and current account of this rapidly evolving field. Structured in eight sections, the book starts with a review of the development and biology of multi-cellular organisms, how they maintain a healthy homeostasis in an individual, and a description of the molecular basis of cancer development. The book then illustrates, as once cells become neoplastic, their signalling network is altered and pathological behaviour follows. It explores the changes that cancer cells can induce in nearby normal tissue, the new relationship established between them and the stroma, and the interaction between the immune system and tumour growth. The authors illustrate the contribution provided by high throughput techniques to map cancer at different levels, from genomic sequencing to cellular metabolic functions, and how information technology, with its vast amounts of data, is integrated with traditional cell biology to provide a global view of the disease. The effect of the different types of treatments on the biology of the neoplastic cells are explored to understand on the one side, why some treatments succeed, and on the other, how they can affect the biology of resistant and recurrent disease. The book concludes by summarizing what we know to date about cancer, and in what direction our understanding of cancer is moving. Edited by leading authorities in the field with an international team of contributors, this book is an essential resource for scholars and professionals working in the wide variety of sub-disciplines that make up today's cancer research and treatment community. It is written not only for consultation, but also for easy cover-to-cover reading.

Lo studio delle malformazioni fetali rappresenta uno degli argomenti piu complessi nell ambito della medicina fetale.

Negli ultimi anni il ruolo della risonanza magnetica (RM) nell inquadramento diagnostico delle malformazioni fetali isolate e complesse e divenuto sempre piu importante, attestandosi come esame di III livello.

Tale incremento e stato possibile grazie all implementazione tecnologica delle apparecchiature di RM e quindi allo sviluppo di sequenze veloci e ultra veloci.

La RM, solitamente effettuata dopo un ecografia di II livello a partire dalla 19a settimana di gravidanza, puo quindi rappresentare, in casi selezionati, un importante completamento diagnostico nella valutazione di quadri malformativi complessi e nella programmazione di interventi terapeutici nella vita intrauterina e nel postnatale. E necessario sottolineare l importanza di centri di riferimento dedicati e la presenza di un team multidisciplinare per la corretta gestione dei piccoli pazienti.

Il volume e suddiviso in tre parti. Dopo una prima parte piu tecnica, viene trattata l anatomia fetale in RM con attenzione all evoluzione dei singoli organi; la terza parte analizza invece i principali quadri malformativi con particolare riguardo al distretto encefalico, toracico e addominale. Il testo e arricchito da un estesa documentazione iconografica.

Questolibro vuole essere di rapida e facile consultazione e rappresentare un punto di partenza per il radiologo e il neuroradiologo, nonche per tutti gli specialisti interessati alla medicina fetale e in particolare alla risonanza magnetica.

Das kindliche Elektroenzephalogramm unterscheidet sich in wesentlichen Punkten vom EEG des Erwachsenen. In jeder Altersgruppe finden sich parallel zur Hirnentwicklung spezifische EEG-Muster, Normvarianten und pathologischen Veranderungen, deren Kenntnis fur die Beurteilung essentiell ist. So gibt es eine Vielzahl altersabhangiger Epilepsieformen und anderer Krankheitsbilder, die im Erwachsenenalter unbekannt sind. Eine besondere Herausforderung stellt die Beurteilung des Neu- und Fruhgeborenen-EEGs dar.

Dieser Leitfaden klart daruber auf, was bei EEG-Ableitungen im Sauglings- und Kleinkindesalter zu berucksichtigen ist und hilft dabei, EEG-Kurven richtig zu interpretieren und pathologische von normalen Mustern abzugrenzen.

Das Buch ist ein unveranderter Nachdruck des gleichnamigen Kapitels aus dem Werk "Klinische Elektroenzephalographie" von Stephan Zschocke und Hans-Christian Hansen. Nutzlich ist es insbesondere fur Kinder- und Jugendarzten und Neurologen, die mit den Grundlagen der Elektroenzephalographie vertraut sind. Einsteigern zum Thema zeigt dieses Buch auf, wo und wann das EEG im Kindesalter einen Beitrag zur Diagnose leisten kann."
