Filter by:Premature ovarian failure (POF) is known to be associated with an increased risk of ocular surface disease (dry eye), likely due to the reduction of both estrogens and androgens seen in this condition. From preliminary data, we suspect that women with Turners syndrome (45, XO), a genetic abnormality that affects sex hormone levels, are also at increased risk of ocular surface disease. Comparing POF and TS women may allow us to distinguish different mechanisms for ocular surface disease, due to the different etiologies of hormonal (estrogen and androgen) alterations posed by POF and TS.
The protein polymorphism of the growth hormone receptor characterized by the genomic deletion of exon 3 has been linked to the magnitude of the first-year-growth response to growth hormone (GH) in girls with Turner syndrome. Objective: to study the long-term effect of GH therapy in Turner syndrome in correlation to this GHR polymorphism in a mainly retrospective design (chart-review).
Primary Objectives: - To determine the effectiveness of the 3-month depot leuprolide in inducing and maintaining secondary amenorrhea in patients undergo hematopoietic stem cell transplantation. - To determine the incidence of regained ovarian function manifested as spontaneous restoration of menstruation and normalization of hormonal level in patients after transplantation and discontinuation of long-acting leuprolide.
Growth hormone treatment is used in girls with Turner syndrome to increase final height. The aim of this study is to evaluate the effect of growth hormone treatment on body composition and heart function in adult women with Turner syndrome. The hypothesis is that the fat mass will decrease and lean body mass will increase. There is only very limited documentation of the effect on the heart in this study population.
The purpose of this study is to evaluate the effectiveness of a modified natural cycle in patients with previous poor response to infertility drugs and high basal FSH, prior to proceeding to oocyte donation or abandoning fertility treatment.
The purpose of this study is to compare ovulation induction using a flexible GnRH antagonist protocol and flare up GnRH agonist protocol in IVF patients with poor response to ovarian stimulation. Our hypothesis is that the antagonist protocol provides better IVF outcomes compared to the flare up protocol in this group of patients.
This study investigated the effect of growth hormone on the growth of infants and toddlers with Turner syndrome during 2 years of treatment with growth hormone. This was compared with the growth of infants and toddlers with Turner syndrome who did not receive any growth hormone treatment. The overall aim was to prevent the growth failure usually seen during this period. The study also looked at middle ear disease, hearing problems, and cognitive and behavioral development.
Women who are affected with premature ovarian failure will exhibit skewed X-chromosome inactivation patterns compared to women with normal menstrual function (as defined by being pregnant), indicating a possible X-chromosome defect.
This is an extension study that will gather long-term data on the effect of early growth hormone (GH) treatment on adult height and other aspects of health and development in girls with Turner syndrome. The main purpose is to determine whether girls who received 2 years of GH treatment before 6 years of age achieve taller adult height than girls who were untreated during this time. The study will also look at middle ear and hearing function, and cognitive and behavioral development. Protocol completion is defined as attainment of height velocity less than or equal to 1.0 cm/year, or bone age greater than or equal to 15 years.
The study aims at identifying the predictive markers after one month of Saizen therapy in Growth Hormone Deficiency (GHD) and Turner Syndrome children.
