Book Description
This fourteenth of 15 short atlases reimagines the classic 5 volume Atlas of Human Central Nervous System Development. This volume presents sections of the spinal cord from specimens between 4 mm and 108 mm with detailed annotations. Extensive 3-D reconstructions show the early development of the germinal zones, the earliest neurons and early white matter accumulations at cervical levels only. Other 3-D reconstructions in older specimens show the progressive segregation of motor neuron columns at all levels in the ventral gray. The Glossary (available separately) gives definitions for all the terms used in this volume and all the others in the Atlas. Key Features Classic anatomical atlases Detailed labeling of the structures in the developing spinal cord offers updated terminology and the identification of unique developmental features, such as germinal matrices of specific neuronal populations and migratory streams of young neurons Appeals to neuroanatomists, developmental biologists, and clinical practitioners A valuable reference work on brain development that will be relevant for decades

This last of 15 short atlases reimagines the classic 5 volume Atlas of Human Central Nervous System Development. This volume presents serial sections of the spinal cord from specimens between 130 mm and 440 mm with detailed annotations. The presentation of these specimens emphasizes the sequence of myelination in various fiber tracts. The Glossary (available separately) gives definitions for all the terms used in this volume and all the others in the Atlas.

Book Description
Based on the famous Donald School courses, this genuinely comprehensive textbook provides a detailed introduction to transvaginal sonography [TVS], the important diagnostic technique widely used in obstetric and gynaecology clinics worldwide. Including an introductory section on the basics of TVS, the text also discusses clinical applications in obstetrics, gynaecology and infertility, as well as the modern techniques of Doppler Sonography, three-dimensional and four-dimensional TVS. The most up-to-date in its field, this book will be welcomed by a wide range of clinicians and sonographers working in women's health.

Book Description
This book offers a unique and focused study of the use of ultrasound during the first trimester, a critical time in a fetus’ development. It includes basic examination guidelines as well as cutting-edge ultrasound modalities, including Doppler and three-dimensional ultrasound, for the period immediately preceding conception through early embryology. Beginning with a discussion of the safety and efficacy of diagnostic ultrasound and the use of this modality for the evaluation and treatment of infertility, recognized experts in the field explore conditions that may interfere with normal conception or development, including maternal diseases that would benefit from early scanning, elements of teratology, multiple gestations, ectopic pregnancy, gestational trophoblastic disease, fetal anomalies and invasive procedures in the first trimester. Numerous illustrations and figures are provided to serve as aids for understanding key concepts. First-Trimester Ultrasound is a valuable resource for many, in or after training, in obstetrics and gynecology, radiology, emergency medicine, family medicine and genetics.

Book Description
Forlagets beskrivelse: The World Health Organization (WHO) recognizes ultrasound as an important medical diagnostic imaging technology. Manuals on ultrasound have been published by WHO since 2001, with the purpose of guiding health professionals on the safe and effective use of ultrasound. Among the diagnostic imaging technologies, ultrasound is the safer and least expensive, and technological advances are making it more user friendly and portable. Ultrasound has many uses, both diagnostic and therapeutic. For the purposes of this manual, only diagnostic ultrasound will be considered and further analysed. Basic physics of ultrasonographic imaging was released in 2005; since then, WHO has addressed the physics, safe use and different applications of ultrasound as an important diagnostic imaging tool. Since it is a non ionizing radiation technology, along with nuclear magnetic resonance imaging, the risks inherent to its use are lower than those presented by other diagnostic imaging technologies using ionizing radiation, such as the radiological technologies (X-rays and computed tomography scanners).

Book Description
Exhaustively illustrated in color with over 1000 photographs, figures, histopathology slides, and sonographs, this uniquely authoritative atlas provides the clinician with a visual guide to diagnosing congenital anomalies, both common and rare, in every organ system in the human fetus. It covers the full range of embryo and fetal pathology, from point of death, autopsy and ultrasound, through specific syndromes, intrauterine problems, organ and system defects to multiple births and conjoined twins. Gross pathologic findings are correlated with sonographic features in order that the reader may confirm visually the diagnosis of congenital abnormalities for all organ systems. Obstetricians, perinatologists, neonatologists, geneticists, anatomic pathologists, and all practitioners of maternal-fetal medicine will find this atlas an invaluable resource.

Book Description
Updated by a team of internationally renowned experts, this book gives a thorough overview of fetal pathophysiology and an evidence base for in utero: both medical (non-invasive) and surgical treatments. Many topics are expanded to cover recent advances, including: stem cell transplantation; tissue scaffolding; minimally invasive approaches to 'open fetal surgery'; the etiology, prevention and treatment of preterm birth and PROM; the genetic etiologies of fetal disease; and gene therapy. In addition, there are in-depth discussions as to the role of open fetal myelomeningocele repair and several fetoscopic approaches to therapy. The international editors have added important new chapters on reducing stillbirth and prenatal counselling. This book is an invaluable reference guide to the latest fetal therapy options, and an essential, in-depth study book for maternal-fetal and neonatology specialists.

Book Description
With an estimated 8,000 deaths per year in the United States from complications of UCA, an initial goal of 50% reduction of loss is possible. To achieve this goal requires the recognition by the obstetrical community of the issue. Recent research into circadian rhythms may help explain why UCA stillbirth is an event between 2:00 a.m. and 4:00 a.m. Melatonin has been described as stimulating uterine contractions through the M2 receptor. Melatonin secretion from the pineal gland begins around 10:00 p.m. and peaks to 60 pg at 3:00 a.m. Serum levels decline to below 10 pg by 6:00 a.m. Uterine stimulation intensifies during maternal sleep, which can be overwhelming to a compromised fetus, especially one experiencing intermittent umbilical cord compression due to UCA. It is now time for the focus to be on screening for UCA, managing UCA prenatally, and delivery of the baby in distress defined by the American College of Obstetricians and Gynecologists as a heart rate of 90 beats per minute for 1 minute on a recorded nonstress test. The ability of ultrasound and magnetic resonance imaging (MRI) to visualize UCA is well documented. The 18 20 week ultrasound review should include the umbilical cord, its characteristics, and description of its placental and fetal attachment. The American Association of Ultrasound Technologists has defined these parameters for umbilical cord abnormalities: B.1.4 Abnormal insertion B.1.5 Vasa previa B.1.6 Abnormal composition B.1.7 Cysts, hematomas, and masses B.1.8 Umbilical cord thrombosis B.1.9 Coiling, collapse, knotting, and prolapse B.1.10 Umbilical cord evaluation with sonography includes the appearance, composition, location, and size of the cord Cord Events: Although many stillbirths are attributed to a cord accident, this diagnosis should be made with caution. Cord abnormalities, including a Nuchal Cord, are found in approximately 30% of normal births and may be an incidental finding. (American College of Obstetrics and Gynecology Practice Bulletin 2009) According to NICHD's recent stillbirth study, UCA is a significant cause of mortality (10%). This finding is in agreement with other international UCA studies. (Bukowski et al. 2011) These histologic criteria identify cases of cord accident as a cause of stillbirth with very high specificity. (Dilated fetal vessels, thrombosis in fetal vessels, avascular placental villi.) (Pediatr Dev Pathol 2012) Finally, defining the morbidity (injury) of cord compression, such as fetal neurologic injury or heart injury identified with umbilical cord blood troponin T levels or pulmonary injury, is the next major area of investigation.
