New chapters place particular emphasis on an update of technological aspects such as ultrasound, molecular genetics, surgery in sex disorders and new problems encountered in reproductive medicine. The book opens with a comprehensive description of the background of infant and adolescent gynecology and diagnostic tools. Several chapters are devoted to the various pathologies encountered in prepubertal and adolescent girls. Contemporary social issues such as sexual abuse, sexually transmitted diseases, contraception for teenagers and teenage pregnancy are also discussed in detail. Presenting a clear plan for clinical management and treatment of frequently encountered problems in prepubertal and adolescent girls, this book should be read by pediatricians, endocrinologists, gynecologists and family practitioners.
