Polycystic Ovary Syndrome: Current Controversies, From The Ovary To The Pancreas (Contemporary Endocrinology Ser.)

by Richard S. Legro Gabor T. Kovacs Fauser, Bart C. J. M.

Polycystic ovary syndrome (PCOS) is one of the most common reproductive health problems of women, causing irregular periods and potential infertility amongst other challenging symptoms. Effective treatment remains a significant challenge and is largely achieved through hormonal medication and lifestyle changes. This third edition covers the aetiology, pathology, impact on fertility and effective medical and surgical management. The content has been thoroughly revised in line with updated guidelines and research developments in the field. A new chapter on the patient's perspective has been included, bringing valuable insight into the lived experience of the condition. Mood disorders and the psychological aspects of PCOS are also covered for the first time. This is a key reference for all clinicians involved in the care of patients with PCOS, including gynaecologists, IVF specialists and reproductive endocrinologists.

Polycystic Ovary Syndrome: Current and Emerging Concepts

by Lubna Pal David B. Seifer

Now in a completely newly revised and expanded second edition, this comprehensive text presents the current state of the art in our understanding and management of polycystic ovary syndrome (PCOS), the most common hormonal disorder of reproductive aged women. The numerous bothersome symptoms of PCOS include menstrual irregularities, hirsutism, acne, scalp hair thinning, weigh excess and infertility; additionally, as they age, women with PCOS are at a higher risk for metabolic abnormalities such as diabetes and dyslipidemias, as well as for cardiovascular disease and even certain cancers. Despite improvements in our understanding of this condition, the exact cause/s of PCOS remain elusive; genetic, hormonal, metabolic and environmental underpinnings are all suggested as relevant. All chapters have been updated, with eight new chapters added across seven thematic sections. Part one discusses the epidemiology of PCOS in both adults and adolescents. Part two covers the pathophysiology of PCOS, including genetics, the hypothalamo-pituitary-ovarian and the hypothalamo-pituitary-adrenal axes, insulin resistance, inflammation, and obesity. The next three sections present the various management strategies, medical and surgical, for harnessing the symptomatology, including PCOS-related infertility; these chapters include added case material to provide real-world examples of the treatments in action and their efficacy. Part six covers the comorbidities that women with PCOS commonly encounter, such as issues of mental health, sleep disturbances, endometrial hyperplasia, and cancer, as well as examines the economic burden of PCOS. The final section discusses emerging concepts surrounding possible mechanisms and potential therapeutic approaches to PCOS, including angiogenic dysfunction, the role of vitamin D, future potential therapies to targeted AMH signaling. The closing chapter, by familiarizing the readers with the intergenerational implications of PCOS and by raising awareness of potential “ripple effects”, aims at alerting the community on a need for vigilance as regards the health of PCOS progeny. With contributions from leaders in the field, Polycystic Ovary Syndrome, Second Edition remains the gold-standard text on this common medical condition and a valuable resource for the wide range of healthcare professionals engaged in caring for the women with PCOS (including but not limited to reproductive endocrinologists, gynecologists, family physicians, dermatologists, mental health professionals), for the aspiring women's health providers of tomorrow, and for the researchers who are striving to unravel the mysteries of the complex entity that PCOS is.

Polyendocrine Disorders and Endocrine Neoplastic Syndromes (Endocrinology)

by Annamaria Colao Marie-Lise Jaffrain-Rea Albert Beckers

This comprehensive reference book is meant to support clinicians in the diagnosis and treatment of polyendocrine diseases and endocrine neoplastic syndromes. Although a large majority of endocrine diseases present as sporadic cases, an increasing proportion can be identified as part of a polyendocrine or systemic syndrome. These include autoimmune endocrine diseases, which may be part of autoimmune polyendocrine disorders (APS) or rare complex disorders such as POEMS (polyneuropathy, organomegaly, endocrinopathy, M-protein and skin changes) or IPEX (immune dysregulation, polyendocrinopathy, enteropathy, X-linked) syndromes. On the other hand, endocrine tumors may develop in a variety of clinical conditions, including multiple endocrine neoplasia (MEN) syndromes, syndromic diseases such as McCune Albright or Carney’s complex, or peculiar familial associations such as pheochromocytoma/paraganglioma syndromes. The book discusses the significant advances that have been made in the clinical and genetic characterization of such entities, with major implications in terms of diagnosis and clinical management - with special attention to emerging syndromes, familial screening , multidisciplinarity and multimodal treatment. This volume is intended for clinicians, residents, specialists and physicians involved in the diagnosis and treatment of affected patients, including specialists in endocrinology, internal medicine, oncology , genetics and imaging.

Polyfluorinated Chemicals and Transformation Products

by Thomas P. Knepper Frank T. Lange

Due to their unparalleled effectiveness and efficiency, polyfluorinated chemicals (PFC) have become essential in numerous technical applications. However, many PFCs brought to market show limited biodegradability, and their environmental persistence combined with toxic and bioaccumulative potential have become a matter of concern in some instances. This volume highlights the synthesis of PFCs, focusing on substances with improved application and environmental properties, which are a challenge for synthetic chemists. Further, modern mass spectrometric techniques for the detection and identification of biotransformation products of PFCs are described. The sorption and leaching behavior of PFC in soil is also addressed in order to predict their fate in the environment. Several contributions discuss the monitoring of PFCs in European surface, ground and drinking waters, treatment options for PFC removal from drinking water, occurrence in food, and the human biomonitoring of PFCs.

Polyglutamine Disorders

by Clévio Nóbrega Luís Pereira de Almeida

This book provides a cutting-edge review of polyglutamine disorders. It primarily focuses on two main aspects: (1) the mechanisms underlying the pathologies’ development and progression, and (2) the therapeutic strategies that are currently being explored to stop or delay disease progression. Polyglutamine (polyQ) disorders are a group of inherited neurodegenerative diseases with a fatal outcome that are caused by an abnormal expansion of a coding trinucleotide repeat (CAG), which is then translated in an abnormal protein with an elongated glutamine tract (Q). To date, nine polyQ disorders have been identified and described: dentatorubral-pallidoluysian atrophy (DRPLA); Huntington’s disease (HD); spinal–bulbar muscular atrophy (SBMA); and six spinocerebellar ataxias (SCA 1, 2, 3, 6, 7, and 17).The genetic basis of polyQ disorders is well established and described, and despite important advances that have opened up the possibility of generating genetic models of the disease, the mechanisms that cause neuronal degeneration are still largely unknown and there is currently no treatment available for these disorders. Further, it is believed that the different polyQ may share some mechanisms and pathways contributing to neurodegeneration and disease progression.
