Summary
Cesarean scar pregnancies can be successfully treated with methotrexate. Multiple doses or a combination of systemic and local methotrexate may be needed for complete remission, with resolution taking several weeks.
Area of Science:
- Reproductive Medicine
- Gynecologic Surgery
- Medical Therapeutics
Background:
- Cesarean scar pregnancy is a rare form of ectopic pregnancy.
- Diagnosis is typically confirmed via transvaginal sonography.
- Treatment options are evolving.
Observation:
- Three cases of cesarean scar pregnancy were treated.
- Transvaginal sonography confirmed gestational sac in the lower uterine segment myometrium.
- Initial systemic methotrexate (50 mg) was insufficient in some cases.
Findings:
- Complete remission was achieved with multiple doses of systemic methotrexate in two cases.
- One case with high beta-hCG and a viable embryo required combined systemic and local methotrexate.
- Biochemical (beta-hCG) and imaging resolution took 7-17 weeks.
Implications:
- Methotrexate is an effective treatment for cesarean scar pregnancy.
- Treatment protocols may need adjustment based on initial beta-hCG levels and embryo viability.
- Further research into optimal dosing and administration is warranted.

01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:29Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...
