the levonorgestrel-releasing intrauterine system We write to report a recent European survey of factors that motivate women to use or reject the levonorgestrel-releasing intrauterine system (LNG-IUS). The survey comprised focus group sessions to identify barriers that prevent women using the LNG-IUS and individual interviews with current users to identify their reasons for having chosen the LNG...

IUD) is thought to act immediately by inhibiting sperm and ovum viability or preventing implantation.2 The LNG-IUS has a different contraceptive mechanism of action that relies on hormonal effects on the endometrium, cervical mucus and uterotubal transport, and thus has a delayed onset.2,3 This is the rationale for advising additional contraception for 7 days if a LNG-IUS is inserted after Day ...

OBJECTIVE The purpose of this study was to investigate if the levonorgestrel-impregnated intrauterine device (LNG-IUS, Mirena(®) ) is safe and effective as therapy for low-risk and medium-risk endometrial hyperplasia compared with oral medroxyprogesterone (MPA). DESIGN A multicentre randomised trial. SETTING Norway. POPULATION In all, 170 women aged 30-70 years with low- or medium-risk en...

Compressor performance for liquefied natural gas (LNG) main refrigeration units is very important due to the direct link between compressor efficiency and LNG production for a fixed amount of power. Dresser-Rand recently designed a series of new stages for the LNG market that provided improved efficiency and a wider range of operation. Industry practice is to rig test new stages prior to applic...

Since the 2004 guidance report by Sandia National Laboratories [1], the use of computational fluid dynamics (CFD) models to simulate LNG vapor dispersion scenarios has been growing steadily, with applications to LNG spills on land as well as on water. Before a CFD model may be applied to predict the vapor dispersion hazard distances for a hypothetical LNG spill scenario, it is necessary for the...

Uterine fibroids are considered to be the most frequently occurring tumours in females. The majority of fibroids do not require any treatment. When symptomatic, the major ailments include abnormal uterine bleeding, painful menstruation, pelvic pressure or pain, urinary problems, constipation, infertility, and recurrent pregnancy loss. Surgery remains a mainstay of symptomatic uterine fibroids t...

BACKGROUND The levonorgestrel-releasing intrauterine system (LNG-IUS) is a highly effective contraceptive. However, during early months of use unscheduled vaginal bleeding is common, sometimes leading to discontinuation. This study aimed to determine whether intermittent administration of progesterone receptor modulator CDB-2914 would suppress unscheduled bleeding during the first 4 months afte...

OBJECTIVES To evaluate the clinical outcomes of gonadotropin-releasing hormone analog (GnRHa) combined with implantation of a levonorgestrel-releasing intrauterine system (LNG-IUS) in adenomyosis patients with significantly enlarged uteruses. SUBJECTS AND METHODS Twenty-one adenomyosis patients whose uterine volumes were greater in size than at 12 weeks' gestation were recruited for the study...

especially in the presence of atypia, has a strong tendency to the development of endo-metrial carcinoma. In this respect, hysterectomy is a preferred treatment for atypical EH. However, for young patient who desire to preserve their fertility or for patients not selected for surgery, conservative treatments using progestin are widely accepted as a treatment option [1]. Oral use of progestin, s...
