Abstract

To evaluate the limits of ambulatory treatment of ectopic pregnancy with an intramuscular injection of 50 mg/m2 methotrexate. Non randomised prospective study from october 1993 and april 1996 at Poissy Hospital. 100 ectopic pregnancies were diagnosed: 54 were treated medically and 46 had a surgical treatment. The mean hCG for the ectopic pregnancies treated medically was 7,273 Ul/ml +/- 12,548 (90-68,220), an ectopic mass was seen in 74% and to precise the diagnosis a currettage was done in 24 cases (44%) if the initial hCG was below 2,000 Ul/ml. The medical treatment was a success for 37 (68.5%) ectopic pregnancies with a mean time of resolution of hCG of 31.9 days +/- 18 (4-90) (with a positive correlation between initial hCG titer and time to resolution of 0.5, p = 0.001). For 15 (27%) patients a second dose of methotrexate was necessary with a 73% success rate and 17 (32%) patients were operated (8 salpingectomies). Sixteen of 20 (80%) demonstrated tubal patency at follow-up hysterosalpingogram and within 7.5 +/- 4 months 26 of 30 (87%) conceived and there was no recurrence of ectopic pregnancy. The medical treatment of ectopic pregnancies with methotrexate has its limits. In our series, if we treat ectopic pregnancies with...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
