The 1973 WHO classification of bladder tumours anticipated a probable need for eventual revision of the criteria for diagnosing papillary and flat bladder neoplasia. A workshop sponsored by the WHO consisting of pathologists, urologists, cytologists, oncologists and basic scientists interested in bladder tumours addressed this subject, and after a follow- -up meeting sponsored by the International Society of Urological Pathology, the classification and terminology used in this text were agreed upon. A major change is in the introduction of a new category: papillary urothelial neoplasm of low malignant potential. Many of the tumours previously designated as papillary transitional cell carcinoma, grade I now fall into that category. Another major change is in the designation of flat lesions, and this includes a definition of carcinoma in situ. Furthermore, a number of variant forms of urothelials carcinomas are included as well as new entities not recognized when the 1st edition was issued.
Preparatory work for this monograph started in 1988 and 1989. The motive was provided by certain incongruities in the illustra- tion of descensus testis for the chapter "Entwicklung der Genital- organe" in the book Humanembryologie. The evoked discussion was reason enough for our own re- search on the phenomenon and uncertainties of testicular des- cent in human. The basis ofthese investigations was the collection of human embryos founded by Prof. Hinrichsen in 1970 at the Department of Anatomy and Embryology, Ruhr-University Bo- chum. The preparation of the material used in this paper has been done with the help of many staff members of our department to whom we feel obliged. We are especially indebted to Prof. Hin- richsen who prepared the foetuses and took the first steps of this project. We wish also to acknowledge Dr. Heinz Jiirgen Jacob for careful fixation and microdissection of specimens intended for scanning electron microscopy. Weare also grateful to Mrs. Vera Mannheim for her involvement and her sensitivity in making scanning electron micrographs, and Mrs. Antje Jaeger for provid- ing an expert and skilful photographic technique especially in the setting up of micrographs. Our thanks are also due to Mrs. Marion Kohn for skilful technical assistance and to all those technical assistants who worked in our department during the past 25 years and who were engaged in providing the serial sec- tions. The English text has been thoroughly revised by Prof. Dr.
What is the function of the mammillary body? Which information is passed through the cuneate fasciculus or the internal arcuate fibers? Which hormones are produced by the paraventricular hypothalamic nucleus? Which nerves and vessels run through the jugular foramen? Which parts of the body are innervated by the accessory nerve? Which cortical regions are affected by a dysfunction of the central sulcus artery?These are frequently asked questions to which a short and precise answer is seldom found in textbooks or other scientific works. These questions - and more - are now answered in the long-awaited Dictionary of Human Neuroanatomy. It will be a useful companion for everyone looking for precise and functional definitions of terms in the field of neuroanatomy, and is absolutely essential for those studying neuroanatomy, and for quick reference.
The objective of the present work is to review the existing literature on joint incongruity, cellular mechano-transduction, and computer simulations of mechano-adaptive bone remodelling, and to quantitatively assess the effect of incongruity on load transmission and subchondral mineralisation. Idealised computer models of incongruous joints and a specific anatomically based model of the humero-ulnar joint articulation were analysed with the finite element method, and the results directly compared with experimental and morphological data.
Since the 1980s, ankle arthroplasty has been considered a dubious treatment for painful and degenerated joints. Many of the concerns that existed previously have been solved today. Prosthetic replacement of other joints also took a long time before reaching their present successful status. This is the first book to deal with ankle arthroplasty. International experts have given their opinion on (i) the kinematics of the ankle; (ii) the basics of replacing the ankle joint; and (iii) the current status of several modern ankle-prosthesis designs. A better understanding of the ankle kinematics, alignment techniques and biological stabilisation and the results of newer designs have changed the former attitude worldwide. The content of this book bears evidence for this change in opinion.
This book reflects practical approaches to answering a variety of biological and medical questions using DNA fingerprinting and genetic profiling in a broad sense that also includes statistical evaluation of the data. It has been written for biology, biochemistry and medical students, graduates, postdoctoral fellows, academic teachers and for all researchers in the theoretical and applied sciences wherever genetic identification and relationship analysis are required.
This classification represents a project aimed at bringing together the variety of ways thymic epithelial neoplasms have been classified. It focuses on their growth characteristics, and cytoarchitectural features . The classification, though restricted to the thymic region rather than the mediastinum in general, also covers neuroendocrine, germ cell, lymphoid, and stromal tumours, as well as tumour-like lesions and the neck tumours of thymic or related branchial pouch derivation.
Investigations on anatomical specimens have demonstrated that the subchondral mineralization does indeed show regular distribution patterns from which conclusions about the mechanical situation within an individual joint may be drawn. Since radiographical densitometry and histological methods are only available for determining the adaptive reaction of the bone to the mechanical situation in a joint after death, the information obtained applies only to an end situation and tells us nothing about the development of the changes with time. Furthermore, investigations carried out on human specimens by radiographical densitometry mostly apply to samples of a particular age, since such specimens can be acquired only from departments of pathology, forensic medicine or anatomy.
Glomerular flltration represents one of the basic mechanisms in the function of an organism. Our understanding of this process is still quite fragmentary. Regulation of blood flow and pressure, together with regulation of the ultraflltration coefficient (which is an attribute of the flltration barrier), are the two fundamental mechanisms accounting for maintenance and adaptability of glomerular flltration. Regulation of glomerular blood flow is generally considered to result from an interplay between afferent and efferent glomerular arterioles, and much progress has been made recently in understanding this interplay (Navar et al. 1996). The present study provides a detailed structural description of the glomerular vascular pole of rat. The results of this study appear to be relevant for several open questions of glomerular function. First, the interaction between afferent and efferent arterioles in regulating glomerular blood is generally understood to occur between the preglomerular and the postglomerular portions of these vessels. As shown in the present study, the structural elaborations of these arterioles and the spatial relationships between them within the glomerular hilum strongly suggest an interplay also at this site. Moreover, the current understanding of glomerular blood flow regulation by tuning the interplay between afferent and efferent arterioles is exclusively based on signals whose regulatory loops are established in follow-up events outside the glomerulus (tubuloglomerular balance, tubuloglomerular feedback).
With 38 specialist contributors, the author provides detailed guidelines for preparing histopathology reports, the interface between pathologists and clinicians. Organized on a systematic basis, the book provides lists of histopathological features to be considered and numerous specimen reports.;This book should be of interest to trainee pathologists and house officers; trainee clinicians; MRCPath students.
}This eloquent book takes us on a spell-binding journey into the workings of our bodies in health and disease. Dr. Charles A. Pasternak captivates us with his vivid and even poetic explanations of what keeps us healthy and vital, and what tears away at our health. He possesses the gift for rendering complex topics clear and lyrical, as in the ways our molecules interact with one another to decide the fate of our heart, brain, and lungs---whether we live or die.Why does disease rear its ugly head? Why does cancer take hold in some of us and pass by others? What roles do nutrition and stress play in determining our chances for a long, fulfilling life? Can we hold our eventual demise at bay by trying novel drugs and therapies? Dr. Pasternak also explores to what extent the illnesses we sufferand even our level of intelligenceare dependent on the genes we inherit from our parents, or the food we eat, or even the environment we inhabit. The story of our bodies is a true saga that has never before been so engrossingly told. }
This is a classification of tumours and tumour-like lesions of the liver. It is based primarily on the microscopic characteristics of the tumours, and is therefore concerned with morphologically identi- fiable cell types and histological patterns. The haematoxylin- and eosin-stained section remains the mainstay of morphological diag- nosis, but special histochemical stains are often helpful and have been referred to in the explanatory notes. Readers interested in specific special stains mentioned in the text should consult Labora- tory Methods in Histotechnology of the Armed Forces Institute of *Pathology, Washington, D. c., USA. 1 The results of immunohisto- chemical methods for identifying various tumour "markers" have also been noted whenever indicated. The present classification incorporates all the previously classi- fied tumours, but also includes several new lesions, viz. biliary papil- lomatosis, the fibrolamellar variant of hepatocellular carcinoma and epithelioid haemangioendothelioma. Several subtypes of hepato- blastoma are mentioned. A serous type of bile duct cystadenoma is described. The section on tumour-like lesions has been expanded to include focal fatty change and inflammatory pseudotumour. The section on adenomatous hyperplasia, including macroregenerative nodules, has been amplified. The number of photomicrographs has been increased from the original 56 to 150. Unlike the first edition, the photomicrographs in the second edition are mostly black and white. All are new and were taken of representative cases on file at the Armed Forces Institute of Pathology.
1. 1 Scientific Aims In recent years, there has been a definite trend away from the casuistic scientific thinking which has dominated the scientific world, at least in the field of medicobi ological research. Now, in the last decade of this century, scientists are returning to a conceptual way of thinking that characterized the beginning of this century, namely organismal thinking. The holistic concept is not a new one; it was rekindled by a small group of scientists who, in the previous two decades, have begun to warn against too great an emphasis being placed on a molecular casuistic approach as the final pursuit to science (see Duncker 1983). These thinkers were perhaps instrumental in helping to turn the tide, to instruct and encourage fellow researchers to extend their findings from the molecular and to the organismal (see Duncker 1983, 1992a, b; Duncker and Kreite 1987). Having observed the ceca of many different animals for many years and having described their morphology at different levels of study -from the macroscopic to the electron microscopy level - the need to compare and observe these morphological entities in a quantitiative way became increasingly imminent. Quantitative methodol ogy in morphology requires the use of morphometry, which in the most general terms can be described as the measurement of the forms of animals. As defined by Reith and Meyhew (1988), it is quantitative morphology, i. e., the measurement of structures by any method, including stereology."
In the last few years, considerable attention has been paid to the presence of insulin-like growth factors (IGFs) and their binding proteins (IGF-BPs) in the brain and peripheral neuronal tissue. IGFs are synthesized within the CNS, are bound to specific IGF-BPs and act on specific receptors. They represent a new class of growth factors and messengers in the brain and the periphery. Written by a group of outstanding experts in the field, the book provides an invaluable forum where important aspects of the production, regulation, biological actions, pathophysiological involvement, therapeutic applications for IGFs in many neurologic and neuromuscular disorders are addressed and critically evaluated.
This book differs from others in the Histological Typing series by including more clinical aspects and by concentrating on cancer and precancer of the oral mucosa rather than attempting to cover all benign and malignant tumors of the oral and oropharyngeal tissue. One main aim is to inform general pathologists of the significance of the clinical features of the various lesions discussed as, on the whole, they may be unfamiliar with this territory. Attention is also drawn to those conditions particular to the oral mucosa that may give rise to appearances which are important in differential diagnoses but can be misleading to the pathologist who does not have detailed knowledge of the tissue involved. The TNM-classification for malignant tumors of the lip and oral cavity is also included.

During the two decades since the publication of the first edition of Histological Typing of Bone Tumours, new methods of diagnosis, es- pecially radiological imaging techniques (computed tomography and magnetic resonance imaging), associated with advances in the new cytomorphological methods including immunohistochemistry, DNA ploidy analysis, cytogenetic chromosomal investigation, etc., have greatly improved our diagnostic tools and treatment results. These advances are reflected by the publication of new editions of various important textbooks in recent years. In these publications classifica- tion criteria differed. In contrast, the WHO classification has been relatively unaltered, and has introduced a limited number of new entities and subdivided others because of distinct histological features and biological be- haviour. In general the framework and the concept of the original classifi- cation, as it has been widely accepted, remains essentially unchanged. The classification is based on the line of histological differentiation, in many instances reflecting the type of intercellular matrix material produced. This approach is justified because it avoids theoretical his- togenetic controversies.
