Disorders of the Female Reproductive System

3.8K
The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...

Oogenesis02:07

Oogenesis

68.9K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.6K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Summary
This summary is machine-generated.

Postmenopausal vaginal bleeding often indicates endometrial cancer, affecting 90% of patients. Early evaluation with imaging and biopsy is crucial for timely diagnosis and treatment of this gynecologic malignancy.

Area of Science:

  • Gynecologic Oncology
  • Pathology
  • Radiology

Background:

  • Postmenopausal vaginal bleeding is a significant symptom in 90% of endometrial cancer cases.
  • Risk factors include obesity, advanced age, type 2 diabetes, unopposed estrogen use, PCOS, chronic anovulation, and family history.
  • Endometrial intraepithelial neoplasia is a precursor to endometrioid adenocarcinoma, necessitating prompt gynecologic oncology referral.

Purpose of the Study:

  • To outline the diagnostic evaluation of postmenopausal vaginal bleeding.
  • To emphasize the role of imaging and biopsy in identifying endometrial cancer.
  • To highlight the importance of early detection and management by family physicians.

Main Methods:

  • Detailed patient history and physical examination focusing on bleeding, pain, and discharge.
  • Transvaginal ultrasonography to assess endometrial thickness.
  • Endometrial biopsy for histological examination.

Main Results:

  • An endometrial thickness of ≤4 mm in postmenopausal patients has >99% negative predictive value for endometrial cancer.
  • Endometrial intraepithelial neoplasia is a critical finding indicating a precursor lesion.
  • Persistent or changed uterine bleeding warrants biopsy.

Conclusions:

  • Family physicians are vital for early endometrial cancer identification and patient management.
  • Transvaginal ultrasonography and endometrial biopsy are key diagnostic tools.
  • Careful consideration of risks/benefits is needed when deferring biopsy, especially with atrophic endometrium.
