Available in PDF, EPUB and Kindle. Book excerpt: Ferment, a sign of progress in any scientific field, has previously been lacking in the area of cryptorchidism, where the only activity has been in improving operative methods. Now, however, profound changes in the care of boys with cryptorchidism are being brought about; ideas are arising from a fresh look at comparative anatomy, and histological and experimental observa tions are being supplemented by clinical tests made possible by new hormonal agents. The treatment of cryptorchidism begins with its recognition by the pediatri cian, who until now has shown little interest because of disappointing results from chorionic gonadotropin administration. As for the surgeon, his bent toward restoration of normal anatomical relationships has kept his attention focused on the development of better surgical technics to bring the recalci trant testis into the scrotum. Both specialists have avoided the primordial question of why the testis did not descend properly. If this were known they would treat the cause of cryptorchidism, and not be satisfied merely with trying to correct its end result. As one reads this book, one sees that in most patients cryptorchidism is not caused by some anatomical structure blocking the way or by some deformity of the testis interfering with the transport mechanism. Rather, deficiencies in the hormonal environment of the fetus retard the developmen tal sequences essential to the normal differentiation and descent of the testis. The clinical solution is thus to provide the deficient substances.

Download or read book Descent of the Testis written by John M. Hutson and published by Springer. This book was released on 2015-12-18 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a state of the art overview of all aspects of testicular descent and cryptorchidism, including the mechanisms of descent and the causes, consequences, diagnosis, and treatment of undescended testis. The advances in understanding that have been achieved over the past two decades are clearly explained, covering the latest genetic information on the causes of normal and abnormal testicular descent, the role of INSL3 in transabdominal migration, and the evidence that a neurotransmitter released from the genitofemoral nerve mediates androgenic control of inguinoscrotal descent. Exciting changes in the management of both congenital and acquired cryptorchidism, such as the widespread use of laparoscopy for impalpable testes inside the abdominal cavity, are fully described. Evidence for the benefits of orchidopexy within the first year of life is reviewed, and an individual chapter is also devoted to hormonal treatment. Throughout the book due attention is given to ongoing controversies and divergences of opinion. This new edition of Descent of the Testis will be a timely update and valuable reference for all who are involved in research into testicular descent and management of cryptorchidism.
Download or read book The Cryptorchid Testis written by Thomas O. Abney and published by CRC Press. This book was released on 2020-08-11 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current knowledge concerning both morphological and functional cryptorchid-related alterations in the various testicular compartments is summarized in this valuable new publication. Damage to the germinal epithelium and resulting infertility in both humans and experimental animals as well as the degree of damage to the different stages of germ cell development is discussed. In addition, information concerning hormonal therapy and orchidopexy to reverse cryptorchid-related damage is provided. Morphological alterations in Sertoli and Leydig cells is discussed in terms of cellular hypertrophy and hyperplasia, alterations in organelle number and characteristics as well as changes in cell-cell junctional complexes. Changes in Sertoli cell and Leydig cell function, including gonadotropin binding, steroidogenesis and other metabolic alterations is also outlined,as well as the influence of altered testicular function on subsequent hypothalamic-pituitary changes. Vascular disruption, the potential role of paracrine substances and direct thermal damage, all of which may be responsible for the resulting detrimental changes in one or more testicular compartments, are considered.
Download or read book Cryptorchidism written by F. Hadziselimovic and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cytological techniques have greatly improved in the last twenty years, largely as a result of further development of the microscope. Electron microscopy, in particular, has opened up great prospects for the study of cell morphology, while the develop ment of radio-immuno-assay has brought great progress in endocrinology. The applica tion of these two techniques, which are complementary to each other and provide mutually supporting evidence, is the subject of this monograph. The work is divided into two parts. The first deals with the ultrastructure of normal testicular development, describing four main elements of the testicle - the germ cells, the Sertoli cells, the peri tubular connective tissue and the Leydig cell- with details of their individual development. To make the electron micrographs more easily understandable, diagrams have been used to explain the most important points. The second part deals with cryptorchid testicles, including the primary and sec ondary changes involved and morphometric studies of the secondary changes. The significance of these ultrastructural observations for the treatment of cryptorchidism is emphasized. With the aid of radio-immuno-assay the level of testosterone in cryp torchid mice was determined and comparisons drawn between the ultrastructural changes in cryptorchidism in mouse and man. The experimental studies served as a basis for the hypothesis that, in all probability, a congenital disturbance of the hy pothalamo-hypophyso-gonadal axis is responsible for cryptorchidism. I hope that this monograph will contribute towards a better understanding of normal and cryptorchid testicular development and of the etiology of cryptorchidism.
Download or read book Atlas on the Human Testis written by Davor Ježek and published by Springer Science & Business Media. This book was released on 2012-10-17 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlas on the Human Testis: Normal Morphology and Pathology presents histological illustrative material from paraffin and semi-thin sections of the human testis which are routinely used in the assessment of testicular morphology, allowing an early detection of carcinoma in situ and more advanced pathological changes of the testicular parenchyma. The early detection of cancer in situ is based on the careful morphological investigation of the biopsy and immunohistochemistry (IHC). Therefore, this atlas contains detailed descriptions of IHC methods as well as modern molecular biological methods such as DNA microarrays and proteomics and advanced microscopy techniques related to the testicular biopsy. Adequate evaluation of the testicular biopsy leads to high cure rates of testicular neoplasms which can be used as a basis to successfully treat infertility in men. Atlas on the Human Testis: Normal Morphology and Pathology is a valuable reference tool which will appeal to andrologists, urologists, pathologists, clinical embryologists, as well as reproductive biology scientists.

Available in PDF, EPUB and Kindle. Book excerpt: During the past decade extensive investigations have been done on the testis. Since the observations have been published in many different journals. it seemed appropriate to bring together and summarize some of the pertinent findings in a single volume. Twenty-eight scientists and clinicians from nine countries have contributed to this book. They have reviewed the literature and presented their own, new observations on the developmentaL anatomicaL physiologicaL biochemical and pathological aspects of the descended and cryptorchid testis. In addition, several contributors have evaluated the usefulness of certain animals as models for systematically studying specific aspects of cryptorchidism. It is hoped that this volume will serve as a useful summary and reference for those working in this area and that it will encourage further research in testicular physiopathology. The editor thanks the contributors for their enthusiasm, cooperation and meticulous writing of the chapters. The support of the Departments of GynecologyjObstetrics and the Department of Physiology of Wayne State University School of Medicine. Detroit and the assistance from the staff of Martinus Nijhoff are gratefully acknowledged. The cheerful cooperation of Miss Lori Rust and Miss Penny Stoops who helped to type and assemble the volume is most deeply appreciated.
Download or read book The Testicular Descent in Human written by K.J. Barteczko and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The testicular descent (descensus testis) is described in a complete series of human material from stage 14 CC to the adult state by using own phases. Central points of interest in this work are answers to questions which have been discussed controversially by generations of scientists and which are wrong or inadequately documented in most textbooks of embryology: Does an inner gonadal descent exist? What about origin, role and fate of gubernaculum H., processus vaginalis peritonei and gonadal ligaments? How do the annexes of testis come into their final position? The results are based on serial sections, scanning electron microscopy, three-dimensional reconstructions, microdissection and immunohistochemistry.

Download or read book Cerebral Palsy written by Freeman Miller and published by JHU Press. This book was released on 2006-05-08 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: When a child has a health problem, parents want answers. But when a child has cerebral palsy, the answers don't come quickly. A diagnosis of this complex group of chronic conditions affecting movement and coordination is difficult to make and is typically delayed until the child is eighteen months old. Although the condition may be mild or severe, even general predictions about long-term prognosis seldom come before the child's second birthday. Written by a team of experts associated with the Cerebral Palsy Program at the Alfred I. duPont Hospital for Children, this authoritative resource provides parents and families with vital information that can help them cope with uncertainty. Thoroughly updated and revised to incorporate the latest medical advances, the second edition is a comprehensive guide to cerebral palsy. The book is organized into three parts. In the first, the authors describe specific patterns of involvement (hemiplegia, diplegia, quadriplegia), explain the medical and psychosocial implications of these conditions, and tell parents how to be effective advocates for their child. In the second part, the authors provide a wealth of practical advice about caregiving from nutrition to mobility. Part three features an extensive alphabetically arranged encyclopedia that defines and describes medical terms and diagnoses, medical and surgical procedures, and orthopedic and other assistive devices. Also included are lists of resources and recommended reading.

Download or read book Infertility in the Male written by Larry I. Lipshultz and published by Cambridge University Press. This book was released on 2009-09-24 with total page 691 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new edition of this canonical text on male reproductive medicine will cement the book's market-leading position. Practitioners across many specialties - including urologists, gynecologists, reproductive endocrinologists, medical endocrinologists and many in internal medicine and family practice – will see men with suboptimal fertility and reproductive problems. The book provides an excellent source of timely, well-considered information for those training in this young and rapidly evolving field. While several recent books provide targeted 'cookbooks' for those in a male reproductive laboratory, or quick reference for practising generalists, the modern, comprehensive reference providing both a background for male reproductive medicine as well as clinical practice information based on that foundation has been lacking until now. The book has been extensively revised with a particular focus on modern molecular medicine. Appropriate therapeutic interventions are highlighted throughout.
