T HE prediction of the probability of the safe passage of the fetus through the birth canal is the primary function of the attendant at the start of labor. The means of determining the relative size of the fetal head and the internal diameters of the pelvis have therefore been the objects of deep concern down through the centuries. Manual techniques of clinical evaluation of cephalo-pelvic relations reached their peak a generation or two ago. A massive nomenclature existed with respect to pelvic planes and diam eters. To these were related various positions, attitudes, stations, and synclitisms of the fetal head. Measurements depended on digital efforts to explore the interior and on dubious implications drawn from external pelvimetry. The mechanisms of labor, as it might occur under the innumerable possible pelvic measure ments and fetal orientations, were the subject of hours of stu dent drilling and remained a lifelong preoccupation of the most seasoned specialist. The increasing safety of cesarean section somewhat miti gated the consequences of error. When a borderline internal conjugate was digitally determined, a trial labor might be per mitted with the assurance that an ultimate solution was in reserve. Mistakes of two kinds persisted, however. On the one hand, trial labor might be permitted to continue too long and, with penicillin not yet discovered, a delayed cesarean section v vi Foreword could be perilous. Alternately, to be on the safe side, many un necessary elective sections might be carried out.

This birefs examines mortality among young children in the period from the seventeenth to the nineteenth century. It does so using several types and sources of information from the census unit England and Wales, and from Ireland. The sources of information used in this study include memoirs, diaries, poems, church records and numerical accounts. They offer descriptions of the quality of life and child mortality over the three centuries under study. Additional sources for the nineteenth century are two census-derived numerical indexes of the quality of life. They are the VICQUAL index for England and Wales, and the QUALEIRE index for Ireland. Statistical procedures have been applied to the numbers provided by the sources with the aim to identify effects of and associations between such variables as gender, age, and social background. The briefs examines the results to consider the impact of children's deaths upon parents and families, and concludes that there are differences and continuities across the centuries.

The recognition of normal and abnormal patterns in the breast by mammography is a skill that must be acquired through training and experience in the same way the radiologist learns to recognize the normal or abnormal skull, gastrointestinal tract, chest, spine, and other anatomy. To disseminate information on the breasts to radiologists on a large scale, the most effective method - person-to-person teaching - is obviously impractical. Even postgraduate courses in mammography can reach but a few fellow radiologists. Therefore we have felt for some time that a teaching Atlas of "1lalJlJJJography would serve a useful purpose, within the limita tions of the method, by bringing to the attention of radiologists and physicians in general the salient features of the X-ray appearance of the normal and the abnormal breast. In mammography as in no other area of roentgenologic study, technique is of crucial importance. Accurate diagnosis is abso lutely dependent upon demonstration of very fine detail, some times as delicate as a linear strand or two, or minute specks of calcium. To some extent the pictorial representation embraced by an atlas defeats the teaching objective, for much fine detail is often lost in reproducing radiographs. Every effort has been made to obtain the best possible reproductions of mammo grams in this Atlas) but some illustrations must of necessity remain unconvincing to the reader. Some of the details describ ed will be appreciated only when viewing a good quality original radiograph."

The chapters in this book represent presentations at the first meeting ever held on the regulation and actions of follicle stimulating hormone. The meeting took place on the campus of Northwestern University, Evanston, Illinois, from October 25 to 28, 1990. The idea for this meeting was conceived by Neena B. Schwartz, and the valuable advice of the organizing committee contributed greatly to its scientific success. We gratefully acknowledge the funding and coordination of this meeting by Serono Symposia, USA. We also wish to acknowledge the financial contributions made by Northwestern University. We especially thank the invited speakers, poster presenters, and discussion participants who pro vided the science, interest, and enthusiasm that made this meeting on FSH a success.

The International Women's Health Coalition was pleased to be the convenor and host of the first Christopher Tietze International Symposium, held in Berlin in September 1985. The papers in this volume represent a wide range of international views and experience with the prevention and treatment of contraceptive failure. We believe the issues discussed at the Tietze Symposium to be of interest and concern to women throughout the world and to those who would serve them. The Coalition intends to l1'ive broad distribution to this volume and encourages those interested in these issues to be in touch with the Coalition in New York City (see address below). We would like to thank The Ford Foundation, Stewart Mott, The David and Lucile Packard Foundation, the Population Crisis Committee, and The Uockefeller Foundation for their support of this Symposium. In particular we would like to express our appreciation to Sarah Lewit Tietze and Uta Landy for the devotion ann dedication which made this Symposium possible and a worthy memorial to Christopher Tietze.

The Helene Harris Memorial Trust has become recognized as providing one of the most important international fora for the presentation of research in ovarian cancer. Four biennial meetings have taken place, the most recent of which was held between May 11-14, 1993, in Toronto, Canada. This forum has grown in stature from its inception in 1987 and has brought together interdisciplinary clinical and scientific researchers from around the world who are endeavouring to perform 'cutting edge' studies in the field. The assembled group of presti gious investigators met on this occasion to present their data, to exchange ideas, and to arrange collaborations with the goal of developing new means of detection, treatment and cure of ovarian cancer. The incentive for the establishment of the Trust and its international forum was the prema ture loss through ovarian cancer of Helene Harris, the wife of Mr John Harris. Mr Harris and the Trustees looked for a meaningful way to honour the memory of Helene and to advance the noble cause of gaining an increase in the scientific knowledge of the subject. For those of us who spend most of our waking hours assisting patients and their families who are devastated by this disease, the Trust's generosity provides inspiration, hope and the opportunity for their practical application in a unique professional forum.

This volume contains papers presented at the Conference on the Demographic and Programmatic Consequences of Contraceptive In novations, which was sponsored by the Committee on Population and held at the National Academy of Sciences, October 6-7, 1988. The papers consider how new contraceptive methods currently being developed and changes in the use of already available contraceptives could affect contraceptive practice, levels and patterns of abortion use, and the health of women. In addition, several of the papers re view the probable consequences of introducing new technology into family planning programs in developing countries. The Committee on Population sponsored this conference in order to stimulate think ing and to provide a forum for scientists, family planning program managers, and donor agency personnel to exchange information and ideas about these important issues. The committee is publishing these papers to expand the discussion of consequences of contracep tive innovations and to give scientists, policy makers, and members of the public who could not attend the conference an opportunity to learn about new developments in fertility control and their likely consequences for individuals and the societies in which they live. NEED FOR NEW METHODS While a strong case can be made that the pill and the intrauterine device (IUD) have contributed to declines in the level of unintended pregnancies around the world, it is also clear that for many couples existing methods present problems.

The treatment of menopausal and postmenopausal symptoms is a focus of considerable debate, on account of both the medical and social factors involved. And perhaps the cause of the greatest current interest and concern is not so much the effectiveness of present-day treatment but its safety. Opinions on the subject vary; and to resolve the arguments we must turn to the results of scientific experiment, both the clinical and biological. It is only by comparing experimental results that it is possible to move forward, albeit slowly, towards a generally agreed consensus based upon objective scientific data. It is for this reason that we are particularly grateful to Ayerst Laboratories whose support and help have enabled us to turn our original proposal for an International Symposium into a reality. We are also grateful to the publishers for the efficiency with which they have organized the publication of the Proceedings. It is our hope and that of all the distinguished participants that all readers of this volume will be able to find something in it which will stimulate further thought and discussion - even though they may not necessarily agree with all the conclusions expressed - for the success of a Symposium turns not only on the subject under examination but also on the quality of debate and discussion it encourages.

About 21 years ago prenatal diagnosis became part of the physician's diagnostic armamentarium against genetic defects. My first monograph in 1973 (The Prenatal Diagnosis of Hereditary Disorders) critically assessed early progress and enunciated basic principles in the systematic approach to prenatal genetic diagnosis. Six years later and under the current title, a subsequent volume provided the first major reference source on this subject. The present second (effectively third) edition, which was urged in view of the excellent reception of the two earlier volumes, reflects the remarkable growth of this new discipline and points to significant and exciting future developments. Notwithstanding these advances, the use of the new tools and techniques for the benefit of at-risk parents has taken many more years than most anticipated. Key factors have been the lack of teaching of human genetics in medical schools in the preceding decades and the difficulty of educating practicing physicians in a new scientific disci pline. Even today the teaching of genetics in medical schools leaves much to be desired and this will further delay the introduction of newer genetic advances to the bedside."

Interest in sexuality and reproductive function does not cease when people begin to age. Instead, a new set of questions arises. Women want to know if it is safe to have babies in their late thirties and early forties. They want to know more about hot flashes and other symptoms of menopause-which ones are dangerous and which are merely uncomfortable. They are eager to learn about the relative risks and benefits of estrogen replacement therapy. Men, too, are concerned about age-related changes in their sexual function. Experts in reproductive physiology, gerontology, and genetics met at the National Institutes of Health in June of 1984 to discuss these and other concerns about aging and the reproductive system. The conference on Aging, Reproduc tion, and the Climacteric was sponsored by the American Fertility Society, The National Institute on Aging, and the National Institute of Child Health and Human Development. This volume is based on the proceedings of that confer ence."

The image of obstetrics as a largely manipulative art has changed radically in recent years. The risk to a healthy mother of pregnancy and labour has been markedly reduced and morbidity not mortality is the yardstick by which the quality of maternal care is judged. We are now able to devote far more attention to the fetus whose growth patterns and behaviour in utero can be studied in detail by modern and sophisticated technical aids with a resultant improvement in perinatal mortality. A patient with a pre-existing general disease, however, still presents a problem which is best managed by close co-operation between obstetrician and physician. Essential hypertension, diabetes, heart disease, thyroid disease and epilepsy are examples of disorders which require great care throughout pregnancy and during labour if good maternal and fetal results are to be obtained. There are many questions still to be answered. What is the place of hypotensive therapy in essential hypertension complicating pregnancy? When should delivery take place in the pregnant diabetic? How should the patient be delivered? What should be her management during labour? What is the risk of fetal abnormality in the epileptic patient who becomes pregnant whilst on anti-epileptic drugs? These questions and others have been the subject of a recent symposium in the Institute of Obstetrics and Gynaecology.

Endometriosis provides a unique clinical and scientific challenge. It is being diagnosed with increasing frequency and yet we are unsure of the significance of this in many patients. Its appearance varies from a tiny focus of disease to a potently destructive phenomenon. Weare still unsure of the relative value of medical or surgical treatment. The pathogenesis and control of the cellular function of the disease proVide many scientific problems. The presence of a comparative normal epithelium, namely endometrium, provides a unique research opportunity. It is probable that only through basic science research will we be able to solve the clinical dilemmas that endometriosis presents. We felt that it was important to create a book that explored the important scientific and clinical problems. We therefore invited acknowledged experts from both Europe and the United States of America to review their fields. The purpose of these reviews is not only to provide a resource for clinicians and scientists but also to stimulate thought and new ideas for research and treatment. To fulfil that aim we have asked that the authors be more speculative than normal for a volume such as this. We thank them for responding to their task so well and hope that you will feel as stimulated by their efforts as we have been.

Years of involvement, firsthand experience and research at the Menopause Clinic of the Groote Schuur Hospital, Cape Town, exist as the background to this book. The Clinic itself, however, as one of the first in the world to be established, if not the first, has a story and a lesson of its own to offer, and is therefore deserving of a brief description as the preface to the book. In 1967, shortly after Christiaan Barnard had completed the historical first human heart transplant at the Groote Schuur Hospital, I happened to be in West Berlin and was invited to visit a major international pharmaceutical firm. A new female hormone was mentioned, and thereby started my interest in the subject. Upon my return to Cape Town, I spent many hours in the large medical school library and completely surveyed the menopause literature to 1967. I was stunned by its general inadequacy and was bitten by a challenge to clarify what menopause really was, and to define the proper place of hormone replacement therapy.

The no-man's-land between reproductive physiology and immunology is becoming crowded. The last 10 years have seen a revolution in our under standing of many reproductive processes, brought about by the application of ever more sophisticated immunological methods. The increasing precision of these techniques has given us specific ways of assaying, enhancing or blocking hormonal mechanisms to yield more critical and interpretable information. In this volume eleven authors have presented the current status and future prospects of some immunological aspects of reproduction and fertility con trol. These include the relationships between mother and fetus, the diagnosis of pregnancy, the immunological complications seen in clinical management of human reproduction and some novel approaches for immunological control of fertility. We hope that in these chapters we have achieved an up-to-date account of a fast-moving field that calls on several disciplines. We intend the book to provide an adequate background and a current review for research workers and clinicians who wish both to understand the complex mechanisms involved and to develop improved scientific and clinical methods. We hope too that the student and newcomer will find this a useful reference book."

The primary purposes of this volume are: 1. To provide mental health practitioners with a current overview of our knowledge about normal parental development during pregnancy and its relation to fetal development, with particular emphasis on the impact of acute and chronic stress on these developmental processes. 2. To provide an understanding of the general state of the field of pregnancy and childbirth care both in conventional health systems and in alternative options. 3. To provide an understanding of models of consultation and liaison that are adapt ed to the special conditions of pregnancy and childbirth care, as contrasted to the more traditional modes that characterize these activities in medical and surgical hospitals. If there prove to be secondary gains as a result of pursuing these goals, so much the better. The most desirable of these would be a heightening of awareness of the mental health needs of "pregnant families" and of the risks they incur in transition from non parenthood to parenthood, and a more effective level of primary and secondary prevention of childhood mental disorders. These latter goals are more global and perhaps even a bit grandiose. Their attainment could only be documented through a series of carefully designed research projects aimed at measuring long-range developmental outcome in children and families who have experienced appropriate and early intervention during the pregnancy period."

Honourable Chairman, distinguished speakers, ladies and gentlemen, May & Baker, Singapore is proud to play a part in organizing and hosting this symposium. I hope that it is not necessary for me to intro duce myself, as Singapore doctors have received my letter of invitation and overseas delegates have received my letter of welcome. It is my very pleasant duty to introduce our Director of Research, Dr J. A. McFadzean, who has come specially to grace this occasion. Dr McFadzean, Sir, may I invite you to say a few words to this gathering of distinguished participants. TanJoo Hock VUl Welcome It is my privilege on behalf of May & Baker to welcome you here today. We have representatives from nine countries - Singapore, Malaysia, Thailand, Hong Kong, Indonesia, Japan, Norway, Sweden and UK. It is appropriate that this Symposium on Cervagem be held in South-east Asia where so much excellent development work was done with this product. Cervagem has resulted from many years of collaborative research and development between May & Baker and the Ono Pharmaceutical Company of Japan. It has been a most happy collaboration from the time the active ingredient ONO-802 was synthesized by the Ono Company. You will hear today of the stage we have reached with the R&D work."

Yury Verlinskyand Anver Kuliev Reproductive Genetics Institute, Illinois Masonic Medical Center, 836 W. Wellington chicago, IL 60657 Although introduction of a first trimester prenatal diagnosis by chorionic viIIus sampling (CVS) has considerably improved the possibility for prevention of genetic diseases, it requires a selective abortion in case of an affected fetus. Following the direction of an earlier prenatal diagnosis and to avoid the need for abortion, preimplantation genetic diagnosis has been initiated based on polar body removal and pre-embryo biopsy. The First International symposium on Preimplantation Genetics, Chicago, September 17-19, 1990, was organized to explore these important developments, to review the state of knowledge in the field, and to address existing problems to be solved for developing and improving current approaches for preimplantation diagnosis of genetic disorders. A growing interest in the subject was obvious from the wide attendance of the meeting: over 250 scientists from 19 countries participated. This was the first attempt to put together the advances in different areas of basic and applied research relevant to Preimplantation Genetic Diagnosis, with the multidisciplinary scientific program including the sessions on embryology, micromanipulation and biopsy, genetic analysis of gametes and pre-embryos, IVF, gene expression and gene therapy, and ethical and legal issues. The deliberations of the Symposium presented in the above mentioned sessions, which comprise the contents of correspond ing sections of the Proceedings, open a newarea in medical research based on the interaction of IVF and New Genetics."

Dedication to Professor Dr. med. Dr. h. c. mult. Benno Runnebaum on his 65th Anniversary The name of Benno Runnebaum is closely tied to the status of gynaecological endocrinology and reproductive medicine. Therefore, we would like to dedicate this conference book entitled "Fertility Control" to him in recognition of his achieve- ments. Who is Benno Runnebaum? Benno Runnebaum was born on 22 July, 1933, in Ruschendorf, Germany. After taking his A-levels, he studied medicine in Munster, Bonn and Cologne. He graduated from Cologne University in 1961 and then prepared his doctoral thesis on the "Identificati- on and quantification of progesterone, 20a-dihydroprogesterone, 20~-dihydroproge- sterone and 17a-hydroxyprogesterone in the plasma of human placental blood". This Benno Runnebaum VI Preface publication was the first to describe the progestin cycle in the feto-placental unit. His thesis was supported by Professor Dr. med. Dr. h. c. Josef Zander. It was graded "sum- ma cum laude" and won him a scholarship from the National Institute of Health for training in steroid biochemistry at the Biochemical Institute in Salt Lake City (Profes- sor Samuels) in 1962 and 1963. After his return to Germany he worked at the Univer- sity Women's Hospital of Cologne. He received his further specialist training in 1964 at the Heidelberg Women's Hospital, under the chairmanship of his teacher, Professor Zander.

This volume will explore the latest findings in research into the genetics of breast and reproductive cancers, covering the epidemiological aspects of these cancers, their etiology, the effect of environment on genes and cancer etiology, and how research in this area can lead to development of preventative measures and treatments.

It is clear today that several prostaglandins play an important role in the regulation of many of the physiological events of the reproductive organs in the human. Both naturally occurring prostaglandins and their analogues are used routinely in many countries to ripen the cervix and induce labour at term as well as to dilate the cervix and to terminate pregnancy. Prostaglandin biosynthesis inhibitors are widely used in the treatment of primary dysmenorrhoea. The editors have aimed at an accurate, thorough, yet easily under standable review of the status in 1986 of medical knowledge regarding both the physiological importance and the clinical use of prostaglan dins and their inhibitors in obstetrics and gynaecology. I believe this book will be of value for all clinicians concerned with reproductive health. The list of authors guarantees an authoritative and up-to-date review of this active field.

Pelvic pain in the female patient is common in gynaecological practice, but the specialties of general surgery, urology and orthopaedics provide a significant number of patients and problems. These patients may suffer a multitude of symptoms, and only careful analysis and investigation of each individual problem by the doctor concerned will lead to correct diagnosis and management. The subject matter of this book lies in the practice of many specialties, and all are combined here in a coherent whole. This emphasises the close collaboration necessary between family practitioners, junior hospital staff and consultants. The authors are consultants who work together in a busy district general hospital, and their experience and collaboration is evident in the approach to the diagnosis and management of pelvic pain in the female. Emphasis is laid on the careful evaluation of history and examination and the correct interpretation of diagnostic investigations. Full details of radiology, ultrasound scanning, endoscopy, peritoneoscopy and bacteriological investigation are given. Full consultation between members of staff who have special experience in these investigative procedures is of paramount importance. Details of treatment for relief of pain are important to all doctors concerned with this aspect of clinical management. and this section will be of particular value. The blending of these specialties allows full consideration of the problems affecting the patients. Careful management leads to better treatment for the patient and better satisfaction for the doctor.

In this book we have expert urologists and gynaecologists on the two sides of the Atlantic working together with a common interest, the inadequate female urethra. What makes this volume so valuable is that it is not restricted to one speciality or one cult, but bravely (and systematically) presents established principles and practice. Not only is the current knowledge of the anatomy and function of the continence mech anisms defined by experts carefully selected by the two authorities in the field, but this infor mation is directly applied to clinical problems for the reader to use in the care of patients. Because the basics are presented first, and followed by the methods of diagnosis, the sec tions describing each form of treatment, whether medical or surgical, are set on rational bases. These are not cookbook directions. This background is especially valuable because the incontinent female usually has a complicated disorder, each case being different, so that the responsible gynaecologists or urologists must apply as much understanding as technique if their efforts are to achieve dryness. The clear descriptions and illustrations in this book, then, act as guides as much as directives. This second edition builds on the success of the first. All of us trying to help these unfortu nate women will do more for them from having this new edition at hand."
