Active clinical trials for "Pregnancy, Ectopic"

This is a multi-centred randomized controlled trial on the addition of letrozole in the medical management of tubal ectopic pregnancies. Tubal ectopic pregnancies are abnormal pregnancies in the Fallopian tube, rather than in the womb. They occurred in around 1-2% of all pregnancies. Methotrexate (MTX) given by the intramuscular route i.e. systemic, a commonly used drug for cancer , was a widely used alternative for management for unruptured tubal ectopic pregnancies and was recommended as first line treatment for selected women. Letrozole, aromatase inhibitor, can suppose oestradiol level. Combination of letrozole with misprostol has shown to improve the complete abortion rate in miscarriage. As a result, addition of letrozole may cause a higher success rate in the medical treatment of ectopic pregnancy. As the evidence of combination of MTX and letrozole in tubal ectopic pregnancies is not available, the objective of the present study is to evaluate the efficacy of combination of MTX and letrozole compared to MTX alone in women with tubal ectopic pregnancies.

Ectopic Pregnancy is an entity in which a fertilized ovum is implanted outside its normal place, is considered a public health problem worldwide and is one of the main causes of maternal mortality in the first trimester. The availability of high sensitivity methods of detection of gonadotrophins and the use of high resolution transvaginal ultrasonography have allowed an earlier diagnosis of the same, enabling less aggressive treatments such as the use of parenteral MTX, with the intention of avoiding mutilating surgical treatment , preserving the tube and eventually improving future fertility expectations. The surgical treatment is of choice, this can be laparoscopically or by laparotomy. In this case, we need to preserve fertility, the most indicated is linear salpingostomy; In spite of the existence other techniques.

In this study, about 75 women diagnosed with ectopic pregnancy who are referred to the Obstetrics and Gynecology Center of Valiasr Hospital are included in the study. Demographic information including both gynecological and obstetrical data is collected. Ectopic ectopic pregnancy is confirmed by transvaginal ultrasound. The patients are randomly allocated to three groups The first group will receive a single dose of methotrexate The second group will receive letrozole within a 10-day period, twice a day The third group will receive letrozole in a 5-day period three times a day In the first group, the first day of drug injection is counted, and the drug is measured at a dose of 50 mg/m2 and divided intramuscularly. The hcg level is measured on the first day, and the hcg serum level is routinely measured on the fourth, seventh and fourteenth day. In the second group, letrozole is given in the form of 2.5 mg tablets twice a day for 10 days. And on the fourth, seventh and fourteenth day, the HCG level is measured. In the third group, letrozole is given in the form of 2.5 mg tablets 3 times a day for 5 days, and hCG levels are measured on days 4, 7, and 14. Also, the level of blood cells, liver enzymes, urea level and serum creatinine level are measured on the first day and the seventh day after the treatment. The level of antimullerin hormone is measured on the first day and 3 months after the treatment.

To assess the psychological impact of pregnancy of unknown location (PUL) classification pending a final diagnosis.

In a randomized multicenter trial the investigators want to compare the ability of two hCG-based models in correctly classifying EPs as high risk among PULs and correctly classifying IUPs and failed PULs as low risk after two hCG measurements. After the classification of PULs into high or low risk of EP, the clinical management will be the same within each risk group (high and low) regardless of randomization group (which model classified the patients). The clinical management will be according to the management protocol published in a NICE guideline.

This study aims to compare the effectiveness and Safety of Single-port Versus Multi-port Laparoscopic Surgery in the Treatment of Ectopic Pregnancy

Primary Ciliary Dyskinesia associated with abnormalities of lateralization of organs (with existence of a situs inversus in 50% of cases) and secondary fertility disorders related in humans to abnormalities of mobility of sperm but very little data on the structure and function of tubal cilia in women

To further develop a patient care pathway (incorporating a statistical model which uses the values of biomarkers) in routine clinical practice that will aid the diagnosis and management of women with an ectopic pregnancy.

Summary Purpose and Objective: The purpose of this study is to test the feasibility of rapid acquisition of point of care 3D ultrasound in obtaining abdominal and/or pelvic images. The study will use a newly developed acquisition method and post-processing technique to create three dimensional image models of the abdomen and/or pelvis. Study activities and population group. The study population will be a convenience sample of patients of any age presenting to the Emergency Department with complaints necessitating a clinical abdominal and/or pelvic imaging. The study intervention includes acquisition of research ultrasound images, which will not be used for clinical care, and comparison of these images with clinically obtained images. Other clinical data such as surgical and pathology reports will also be reviewed. 3.Data analysis and risk/safety issues. This is a pilot study intended to determine feasibility and to refine image reconstruction algorithms. Research images will be compared to clinical images. Comparison of research images with final diagnosis will also occur. The research intervention, an ultrasound exam, has no known safety risks. The only risk to subjects is loss of confidentiality. This study is observational, not interventional, because the experimental ultrasound will be performed in all subjects and will not be used in the clinical care of patients (consequently, will not have the opportunity to affect clinical outcomes). Experimental images will be reviewed after completion of clinical care and will not be provided to the clinicians caring for the subjects. The investigators are not measuring the effect of the ultrasound examination on the subjects' outcomes.

To further develop the patient care pathway for women classified with a pregnancy of unknown location (PUL) and ectopic pregnancy (EP).
