This book was released on 2019-11-27 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turner syndrome (TS) is a relatively common chromosomal disorder affecting approximately 1 in 2000 live female births. Short stature is the most common clinical presentation of the syndrome; it is observed in 80 % to 100 % of the girls with TS. Growth is stunted to a variable degree at different phases of childhood and adolescence in TS. Although there is consensus on treating growth failure as early as possible, there is ongoing research to ameliorate final height in TS girls. The co-existence of primary ovarian failure in girls with TS further complicates the management of short stature. It remains to be determined what is the best age to begin treatment for pubertal induction and/or maintenance of puberty; the best compound, dose, or protocol to induce puberty. TS patients have increased mortality and morbidity due to cardiovascular (CV) complications and multiple risk factors for ischaemic heart disease, including hypertension, insulin resistance and dyslipidaemia. The CV phenotype can be better assessed through identification of surrogate risk markers and the relationship of these markers with TS - associated traits. There are very few comprehensive studies on the dynamics of arterial tree and the associations of these dynamics with influential factors in young TS patients. Deregulated signalling within the GH-IGF1 axis may extend beyond the realm of physical stature in TS, resulting in effects on the CV system and other organ systems. Although GH deficiency is associated with CV risk, and excess of GH is also associated with increased CV risk. Because TS patients receive supraphysiological doses of GH, there may be increased risks for CV complications, although retrospective studies failed to document such an association. There are still other unknown issues in the area of TS and CV issues such as the definitions of “abnormal” aortic diameters, high blood pressure. There is scarce data regarding how we can prevent catastrophic CV events in girls and women with TS. There is a call for prospective studies regarding the pathogenesis, diagnosis and prevention of CV disease in TS.TS patients usually have psychological problems related to self-confidence and self-respect due to the high burden of health-related issues they have to cope with at different stages of life. There remains controversy on how to support them to accept their differences and empower them to take an active role in their care. This e-book intends to provide insight on hot topics of debate in TS. The e-book is subdivided into small sections to describe the content of the articles such as growth, puberty, cardiovascular issues, metabolic issues, autoimmunity, cognitive and psychosocial issues to facilitate reading. We hope it will serve as a reference tool for clinicians and researchers who are involved in the diagnosis and management of females with TS.
