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.

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.

Written in a simple point by point style for ease of use, this volume covers all aspects of pediatric surgery with emphasis on important points for diagnosis and management. Each chapter covers a topic with emphasis on the most common conditions in neonatal and general pediatric surgery. The text is well illustrated with clinical, operative, radiological, and histopathological color figures and illustrations. The book also presents some of the rare conditions encountered in pediatric surgery, as well as common pediatric urology conditions. An Illustrated Guide to Pediatric Surgery is a useful reference to pediatric surgeons, specialists, fellows and residents, as well as general surgeons, pediatricians, neonatologists, medical students and interns interested in pediatric surgery.

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.

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.

Cryptorchidism is the failure of one or both testes to descend into the scrotum at birth or shortly thereafter, depending on species, or the ascent of previously descended testes later in life. It is the commonest of all congenital conditions in the human representing between 1 and 9% of all male babies born. It is also common in domestic species such as pigs, dogs and horses. Importantly, cryptorchidism is seen as a sentinel of fetal well-being and is associated with other less common ailments such as testis cancer and hypospadias as part of the testicular dysgenesis syndrome (TDS), as well as being linked to maternal smoking and intrauterine growth restriction. It also likely results from maternal exposure to endocrine disrupting chemicals. Surprisingly, we know relatively little about its immediate causes although deficits in fetal hormonal signaling through INSL3 or testosterone and complex genetic susceptibility seem to be involved. The testes may be affected unilaterally or bilaterally with anatomical arrest anywhere between the abdomen to just above the scrotum. Significantly, we need to distinguish between the consequences of cryptorchidism simply due to retention of the testes within the body cavity at abdominal rather than scrotal temperature, and those sequelae which share a common fetal cause. The former are largely correctable by early orchidopexy. In this Research Topic we aim to bring together a broad selection of articles (reviews, original research articles, commentaries and hypotheses) from the leading experts in the field, discussing all aspects of this common congenital condition, and throwing light on its genetic and environmental causes including its relationship to TDS and the biological mechanisms involved, its sequelae, and how these relate to optimal treatment.
