Filter by:Body size and eye function play an essential role in adapting to the environment and human survival. Growth hormone is commonly recognized by its effect on the height of individuals; Although from an evolutionary perspective, the effects of growth hormone on eye development are more important. Although the effect of growth hormone on eye development has not been accurately determined, the results of a number of studies suggest the effect of growth hormone on eye development. Despite the large number of studies that have investigated the effects of growth hormone on height growth, there are few studies that have investigated the effects of growth hormone on the eye. To the best of our knowledge, no study has been conducted to investigate the effect of growth hormone on ocular findings of patients with early or precocious puberty. Therefore, we intend to investigate the effect of growth hormone on ocular findings of patients with early or precocious puberty.
The purpose of the protocol is to assess the efficacy of the triptorelin 6 month PR (Prolonged Release) formulation in suppressing LH (Luteinising hormone) levels to prepubertal levels (defined as a peak LH ≤5 IU/L) after i.v. GnRH (Gonadotropin-releasing Hormone) stimulation at Month 6 (Day 169) in Chinese children with CPP (Central Precocious Puberty).
The COPENHAGEN School Study is a combined cross-sectional and longitudinal study of healthy Danish school children. This study will by clinical examinations and withdrawal of blood samples investigate whether age of pubertal onset is continuing to decline in Denmark over the past 15 years. Furthermore, we will investigate the mechanism driving earlier onset of puberty and the long term health risks of extremely early puberty using Danish registry data
A randomized, single-blinded, parallel design phase I clinical trial to investigate the safety and pharmacokinetics/pharmacodynamics of CKD-841 A-1, CKD-841 D or Leuplin Inj. after subcutaneous injection in postmenopausal female
The purpose of this study is to observe whether the Triptorelin pamoate 15mg (3-month formulation) effectiveness in Chinese population of CPP children has the same or similar trend with that in overseas CPP population. This is measured by assessing the proportion of children who have a suppressed Luteinizing Hormone (LH) response to Gonadotropin Releasing Hormone (GnRH) test performed 3 months after injection of triptorelin.
Effect of Prevalence of Overweight and Obesity(Body Mass Index (BMI)) on Efficacy of herbal medicines(ZiYinXieHuo) in girls sexual Precocity
Over 20% of the population is reporting on "white coat syndrome", manifested as anxiety symptoms and elevated BP during interaction with medical staff. It is estimated that, throughout the life span of children, approximately 15-20% will suffer from some form of a trauma relating to an interaction with health provider. The proposed study aims is to evaluate the correlation between a single preliminary psychological intervention, including providing knowledge and tools for problems solving, and the anxiety level in female patients arriving to Adrenocorticotropic Hormone (ACTH) and Lutenising Releasing Hormone (LRH) test in comparison to the anxiety in patients arriving to the same test without psychological intervention. 20 female patients arriving to ACTH LRH test for puberty stage assessment (performed as part of routine medical care) will be recruited to the study and will be randomized to one of 2 groups. Participants in the intervention group (10 patients) will be required to arrive with their parents an hour prior to the test and will receive a preliminary psychological intervention. The control group will arrive to the ACTH LRH test on the scheduled time and will not receive psychological intervention
childhood obesity and early puberty are closely related, but existing reports usually focus on their relationship from the perspective of phenotype. This study was designed to investigate the association between obesity-related genic polymorphisms and the risk of early puberty in Chinese Han girls.
Uterin fibroids are the most common operation indication for hysterectomy. Dyring laparoscopic hysterectomy the amount of bleeding is a great difficulty.There are a lot of clinical researchs to reduce the haemorrhage during open hysterectomy but not laparoscopic procedure. In ALKU ERH clinic, researchers decided to smaller the size of fibroid by using GnRH analogues before total laparoscopic hysterectomy to reduce the haemorrhage amount.
Precocious puberty and childhood overweight and obesity are important public health problems that both had adverse effects, which including psychological symptom in childhood, short final height or reproductive dysfunction in adulthood, on children's physical and psychological development.The prevalence of precocious puberty and childhood overweight and obesity are both high, and a growing body of epidemiological studies suggested that there was a close relationship of childhood overweight and obesity with puberty development, especially in girls. However, the underlying mechanism between them is unclear. Existing evidence shows that the occurrence of precocious puberty and overweight and obesity are the result of interaction of multiple factors, which consists growth environment and genetics, and many previous studies provided that more overlapping genes existed between obesity and precocious puberty patients, suggesting that common genes may result in these diseases. Therefore, based on a case control study, which will investigate the associations between obesity pleiotropic genes and early puberty, the researchers will collect information related to obesity, growth environment factors and risk genes in this study to evaluate the relationships of these related factors and precocious puberty, and to further explore whether there exists biological interaction effects of these risk factors on sexual precocity. This project has been approved by the Ethics Committee of Shanghai Children's Medical Center.
