Active clinical trials for "Gonadal Dysgenesis"

A randomized, controlled trial in girls with Turner syndrome at least 7 years old and younger than 13 at study entry, to determine the efficacy and safety of Humatrope (somatropin) treatment in promoting linear growth to final height.

This trial is conducted in Europe. The aim of the trial is to induce normal pubertal development in girls with Turner Syndrome in accordance with that of their peers and their individual state psychosocial maturation.

This study evaluates the effect of a specific, multidisciplinary and personalized rehabilitation program compared to usual care, on motor control and functional disability in patients with neuralgic amyotrophy. Half of the participants will start with the 17-week specific rehabilitation program while the other half will first continue their usual care for 17 weeks, after which they will also receive the 17-week specific rehabilitation program.

The development of the brain in females is a result of a combination of factors. During puberty estrogen plays a role in influencing brain development. Cultural and environmental factors also play a role in the development of the brain. Female patients with Turner syndrome lack the ability to produce estrogen due to undeveloped ovaries. Therefore, Turner syndrome is the perfect condition to study how estrogen (or the lack of estrogen) influences a person's behavior and thinking. This study will compare cognitive differences (visual motor skills, visual-spatial, psychosocial behavior, and visual memory) of patients with Turner syndrome to normal patient controls. Researchers will use the Weschler Intelligence Scale for Children-Revised (WISC-R) along with other tests and scales to measure different aspects of the patient's cognitive ability. In addition the study will review patients with Turner syndrome who previously received estrogen replacement as infants and children in a related research study. Researchers hope to demonstrate that estrogen replacement will improve cognition and behavior in girls with Turner syndrome.

This trial is conducted in Asia. The aim of this trial is to evaluate the new liquid somatropin formulation in children with growth hormone deficiency.

Several studies have demonstrated that Turner Syndrome patients have elevated liver enzymes readily suppressible by a short course of HRT. We wanted to estimated quantitative liver functions in a young group of Turner syndrome patients compared to a healthy control group.

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.

This trial is conducted in Europe. The aim of this trial is to study the dose-response relationship and effect of somatropin (Norditropin®) on final height in girls with Turner Syndrome.

This trial is conducted in Europe. The aim of this trial is to assess whether increasing doses of somatropin (Norditropin®) can maintain the initial increase in height velocity and improve final height. This trial has two trial periods, a main period of 4 years and an extension period until final height is reached.

RATIONALE: Turner's syndrome is a disease in which females are missing all or part of one X chromosome and do not produce estrogen. Giving estrogen is standard treatment for girls who have Turner's syndrome. Estrogen may be effective treatment for mental and social functioning problems experienced by girls with Turner's syndrome. PURPOSE: Clinical trial to study the effectiveness of long term estrogen therapy on mental and social functioning in girls who have Turner's syndrome.
