Hypospadias is recognised as one the most common congenital malformations in male newborns, resulting in an abnormal opening of urethral meatus. It is regarded as a multifactorial disorder in which interactions between genetics, maternal and environmental factors lead to hypoplastic development of the ventral side of the penis, either dependently or in an interaction with other factors. This book discusses the risk factors of hypospadias. It also examines the epidemiology and surgical outcomes of hypospadias.

Prader-Willi syndrome (PWS) is a rare, genetic, multisystemic disorder, characterised by short stature, muscular hypotonia, intellectual disability, behavioural and psychological problems and frequently hypogonadism and impaired growth hormone secretion. PWS arises due to loss of function of paternally-expressed, imprinted genes from chromosome region 15q11-q13. In new-borns and infants, the syndrome presents symptoms of muscular hypotonia and nutritional difficulties, which from the age of approximately two years is replaced by hyperphagia often leading to severe obesity. With increasing age the behavioural and psychological problems increase while the muscular hypotonia improves. During the last decades the knowledge of different aspects of PWS has increased and accordingly the treatment possibilities. However, no specific treatment exists and thus problems continue lifelong. Taking care of PWS patients is therefore a demanding task and necessitates a solid knowledge and understanding of the disorder as well as a multidisciplinary approach. This book will provide professionals taking care of patients with PWS with updated and comprehensive information and advise. The content is built up logically and it will be easy to navigate between the chapters, which cover all clinically relevant issues, genetics, signs and symptoms in children and adults, treatment, words from patients and parents, supporting organisations, and from a parent to a PWS patient.

Ten years after the sequencing of the human genome, scientists have developed genetic tests that can predict a person's response to certain drugs, estimate the risk of developing Alzheimer's disease, and make other predictions based on known links between genes and diseases. However, genetic tests have yet to become a routine part of medical care, in part because there is not enough evidence to show they help improve patients' health. The Institute of Medicine (IOM) held a workshop to explore how researchers can gather better evidence more efficiently on the clinical utility of genetic tests. Generating Evidence for Genomic Diagnostic Test Development compares the evidence that is required for decisions regarding clearance, use, and reimbursement, to the evidence that is currently generated. The report also addresses innovative and efficient ways to generate high-quality evidence, as well as barriers to generating this evidence. Generating Evidence for Genomic Diagnostic Test Development contains information that will be of great value to regulators and policymakers, payers, health-care providers, researchers, funders, and evidence-based review groups.

Recent years have seen rapid advances in our understanding of genetic diseases in terms of their molecular origins. The book focuses on DNA mutations which give rise to abnormalities of protein structure and function in genetic disease.

This user-friendly handbook is intended to help the busy physician with that first critical step in clinical diagnosis: how to determine that this is an inherited metabolic disease, and where one goes from here to establish a diagnosis. The well-illustrated text is organised around the clinical presentation of the disease, to facilitate rapid diagnosis, and then clearly explains how to go about identifying the underlying biochemical and genetic lesion. It will therefore complement those more traditional textbooks of metabolic disease which are organised biochemically, but which are of less practical use in the doctor's clinic or surgery. The book is intended to serve as an entrance to the discipline, to help nonexpert physicians and advanced medical trainees to overcome the intimidation they are accustomed to experiencing when dealing with metabolic problems.

The first advanced-level genetics counseling skills resource

As genetic medicine and testing continue to expand, so the role of the genetic counselor is transforming and evolving. "Genetic Counseling Practice: Advanced Concepts and Skills" is the first text to address ways that genetic counselors can deepen their skills to meet expanding practice demands. This timely resource not only helps readers further develop their abilities to gather relevant data and interpret it for patients, it also aids them in surpassing their usual role by truly understanding patient situations, incorporating patient values into clinical practice, providing in-depth support, and facilitating thoroughly informed, autonomous decisions.

Edited by an expert cross-disciplinary team consisting of a genetic counseling program director, a licensed psychologist, and a nurse/bioethicist/family social scientist, this authoritative reference provides specific and detailed instruction in addressing psychosocial aspects of genetic counseling practice and professional development and training issues of genetic counselors.

Provides a "process" view of genetic counselor service provision; i.e., skills that promote desired genetic counseling outcomes are emphasized (such as relationship skills, patient characteristics, client behaviors, and extra-clinical skills)

Includes experiential activities in every chapter to help readers apply concepts and skills

Draws on the experience of widely recognized experts in genetic counseling theory, practice, and research, who serve as chapter authors

Features numerous specific, real-life examples from clinical practice

"Genetic Counseling Practice" addresses issues relevant to practicing genetic counselors as well as students of genetic counseling programs. In addition, oncology nurses, social workers, and psychologists working with genetic counseling patients and families; medical geneticists and physicians training in the field; and physician assistants will also benefit from this resource.

During the last three decades, many laboratories worldwide have dedicated their research activities to understanding the roles of the cerebellum in motor control, cognitive processes and the biology of mental processes, behavioral symptoms and emotion. These advances have been associated with discoveries of new clinical disorders, in particular in the field of genetic ataxias, and the growing number of diseases presents a source of difficulty for clinicians during daily practice. This practical guide summarizes and evaluates current knowledge in the field of cerebellar disorders. Encompassing details of both common and uncommon cerebellar ataxias, including vascular, immune, neoplastic, infectious, traumatic, toxic and inherited disorders, this book will assist clinicians in the diagnosis and management of the full spectrum of cerebellar ataxias encountered in daily practice. Essential reading for clinicians, including general practitioners, neurologists, pediatricians, radiologists, psychiatrists and neuropsychologists, this will also prove a valuable tool for students, trainees and researchers.

Recent advances in genetic methodology are providing important aetiological and developmental information to the growing literature on Attention Deficit Hyperactivity Disorder (ADHD) and related conditions. Attention, Genes and ADHD is the first book to review and integrate both behaviour-genetic and molecular-genetic advances in this area. It brings together international researchers to show how modern techniques may be applied to the investigation of ADHD, and reviews current findings in the field of ADHD and related conditions.
The book looks at the application of behaviour genetic approaches to twin studies, and reviews diagnostic to ADHD, the relationships between reading, spelling and ADHD, and family and genetic influences on speech and speech and language.
Chapters go on to consider the overlaps between ADHD, Oppositional Defiant Disorder and Conduct Disorder and to explore the environmental and genetic influences among these disorders. The neurobiological and genetic relationship between ADHD and Tourette's Disorder is also examined. The book reviews recent advances in molecular genetics - in particular a discussion of Fragile X as a model for a single single gene effects on ADHD, and the application of genetic methods and approaches to the study of candidate genes. Finally, the implications for education and intervention are discussed, and current and future roles of gentic studies of ADHD are explored, as well as implications of the sequencing of the human genome for child psychiatry.

Recent developments in diagnostic and therapeutic aspects of cardiac and neonatal issues have advanced the care of the newborn. In order to achieve excellence in cardiac care, however, close interaction and collaboration of the pediatric cardiologists with neonatologists, pediatricians, general/family practitioners (who care for children), anesthesiologists, cardiac surgeons, pediatric cardiac intensivists, and other subspecialty pediatricians is mandatory. This book provides the reader with up-to-date, evidence-based information in three major areas of neonatology and prenatal and neonatal cardiology. First, it offers an overview of advances in the disciplines of neonatology, prenatal and neonatal cardiology, and neonatal cardiac surgery in making early diagnosis and offering treatment options. Secondly, it presents a multidisciplinary approach to managing infants with congenital heart defects. Finally, it provides evidence-based therapeutic approaches to successfully treat the fetus and the newborn with important neonatal issues and congenital cardiac lesions.This second volume specifically explores issues related to individual cardiac defects, cardiomyopathies, and hypertension and presents a summary and conclusions of both volumes.

An expert assessment of striking recent developments in molecular genetics and their implications for medical practice at present and in the immediate future. Adopting a public health approach the report aims to help medical decision-makers and practitioners understand both the technical basis of progress and its potential to revolutionize the management of numerous diseases. Advances in the prevention and treatment of classical genetic disorders are considered together with newer opportunities opened by knowledge that many common disorders including coronary heart disease and certain cancers have a genetic component. Throughout the report a special effort is made to help planners in developing and developed countries alike reap the full public health benefits of technologies that are becoming increasingly powerful simple and inexpensive to use. Information ranges from a discussion of the state-of-the-art in gene therapy through a tabular summary of treatment results for specific congenital anomalies to advice on ways to integrate simple genetic approaches into everyday medical practice. Relevant ethical social and legal issues are also critically assessed in an effort to provide comprehensive guidance. The report has eight sections. Background information is provided in the first which explains the structure and functions of DNA summarizes knowledge about the genetic basis of both single-gene and multifactorial disorders and traces the spectacular development of DNA technology and diagnostic tests over the past decade. The Human Genome Project - and its potential to transform medical practice on many levels - are also explained in detail. A section on epidemiology discusses factors influencing the frequency of genetic and congenital disorders and describes opportunities for their management and prevention. The impact that these advances will have on the demand for genetic services is also assessed. The large scale of implications for medical practice is underscored in the third section which reviews and interprets growing knowledge about the genetic component of many common disorders including coronary heart disease certain cancers asthma diabetes mental disorders and Alzheimer disease. A comprehensive review of current and future opportunities for prevention including both genetic family studies and population screening is followed by sections covering the basic principles of genetic counseling and opportunities within the context of obstetric care for prenatal diagnosis using ultrasound scanning and DNA technology. The remaining sections offer advice on the organization of genetic services in industrialized and developing countries alike and discuss the ethical social and legal aspects of genetic technology in medicine concluding that the broadest ethical issue in the area of genetic services is their limited availability.

Examines common hereditary diseases and ways of avoiding them, discussing diabetes, heart disease, cancer, alcoholism, and the exploration of one's family medical tree.
