As I gained more interest and expertise in the treatment of endometriosis, I became aware of several articles concluding that if a woman sought treatment for chronic pelvic pain with an internist, the diagnosis would be irritable bowel syndrome (IBS); with a urologist, it would be interstitial cystitis; and with a gynecologist, endometriosis. Moreover, there is an increased propensity for IBS and IC in patients with endometriosis. There also is an increased risk of small intestine bacterial overgrowth (SIBO), as noted by our guest author for this latest installment of the Master Class in Gynecologic Surgery, Iris Orbuch, MD.
Like our guest author, I have also noted increased risk of pelvic floor myalgia. Dr. Orbuch clearly outlines why this occurs. In fact, we can now understand why many patients have multiple pelvic pain–inducing issues compounding their pain secondary to endometriosis and leading to remodeling of the central nervous system. Therefore, it certainly makes sense to follow Dr. Orbuch’s recommendation for a multidisciplinary pre- and postsurgical approach “to downregulate the pain generators.”
Dr. Orbuch is a minimally invasive gynecologic surgeon in Los Angeles who specializes in the treatment of patients diagnosed with endometriosis. Dr. Orbuch serves on the Board of Directors of the Foundation of the American Association of Gynecologic Laparoscopists and has served as the chair of the AAGL’s Special Interest Group on Endometriosis and Reproductive Surgery. She is the coauthor of the book “Beating Endo —How to Reclaim Your Life From Endometriosis” (New York: HarperCollins; 2019). The book is written for patients but addresses many issues discussed in this installment of the Master Class in Gynecologic Surgery.

The perils of CA-125 as a diagnostic tool in patients with adnexal masses
Katherine Tucker, MD
Assistant Professor of Gynecologic Oncology at the University of North Carolina at Chapel Hill.
CA-125, or cancer antigen 125, is an epitope (antigen) on the transmembrane glycoprotein MUC16, or mucin 16. This protein is expressed on the surface of tissue derived from embryonic coelomic and Müllerian epithelium including the reproductive tract. CA-125 is also expressed in other tissue such as the pleura, lungs, pericardium, intestines, and kidneys. MUC16 plays an important role in tumor proliferation, invasiveness, and cell motility.1 In patients with epithelial ovarian cancer (EOC), CA-125 may be found on the surface of ovarian cancer cells. It is shed in the bloodstream and can be quantified using a serum test.
There are a number of CA-125 assays in commercial use, and although none have been deemed to be clinically superior, there can be some differences between assays. It is important, if possible, to use the same assay when following serial CA-125 values. Most frequently, this will mean getting the test through the same laboratory.

Few women identify breast density as a breast cancer risk
Walter Alexander
A qualitative study of breast cancer screening–age women finds that few women identified breast density as a risk factor for breast cancer.
Most women did not feel confident they knew what actions could mitigate breast cancer risk, leading researchers to the conclusion that comprehensive education about breast cancer risks and prevention strategies is needed.
CDC recommends universal hepatitis B screening of adults
Adults should be tested for hepatitis B virus (HBV) at least once in their lifetime, according to updated guidelines from the Centers for Disease Control and Prevention.
This is the first update to HBV screening guidelines since 2008, the agency said.
“Risk-based testing alone has not identified most persons living with chronic HBV infection and is considered inefficient for providers to implement,” the authors write in the new guidance, published in the CDC’s Morbidity and Mortality Weekly Report. “Universal screening of adults for HBV infection is cost-effective, compared with risk-based screening and averts liver disease and death. Although a curative treatment is not yet available, early diagnosis and treatment of chronic HBV infections reduces the risk for cirrhosis, liver cancer, nd death.”
An estimated 580,000 to 2.4 million individuals are living with HBV infection in the United States, and two-thirds may be unaware they are infected, the agency said.
The virus spreads through contact with blood, semen, and other body fluids of an infected person.
The guidance now recommends using the triple panel (HBsAg, anti-HBs, total anti-HBc) for initial screening.
“It can help identify persons who have an active HBV infection and could be linked to care; have [a] resolved infection and might be susceptible to reactivation (for example, immunosuppressed persons); are susceptible and need vaccination; or are vaccinated,” the authors write.
Ectopic pregnancy risk and levonorgestrel-releasing IUD
Diana Swift
Researchers report that use of any levonorgestrel-releasing intrauterine system was associated with a significantly increased risk of ectopic pregnancy, compared with other hormonal contraceptives, in a study published in JAMA.
A national health database analysis headed by Amani Meaidi, MD, PhD, of the Danish Cancer Society Research Center, Cancer Surveillance and Pharmacoepidemiology, in Copenhagen, compared the 13.5-mg with the 19.5-mg and 52-mg dosages of levonorgestrel-releasing intrauterine systems (IUSs).
The hormone content in levonorgestrel-releasing IUSs must be high enough to maintain optimal contraceptive effect but sufficiently low to minimize progestin-related adverse events, Dr. Meaidi and colleagues noted; they advised using the middle dosage of 19.5 mg. All dosages are recommended for contraception, with the highest dosage also recommended for heavy menstrual bleeding.
“If 10,000 women using the hormonal IUD for 1 year were given the 19.5-mg hormonal IUD instead of the 13.5-mg hormonal IUD, around nine ectopic pregnancies would be avoided,” Dr. Meaidi said in an interview.
EPA seeks to limit ‘forever’ chemicals in U.S. drinking water
The Environmental Protection Agency is proposing a new rule that would greatly limit the concentration of endocrine-disrupting “forever” chemicals in drinking water.
The EPA on Tuesday announced the proposed National Primary Drinking Water Regulation (NPDWR) for six polyfluoroalkyl substances, more commonly known as PFAS, which are human-made chemicals used as oil and water repellents and coatings for common products including cookware, carpets, and textiles. Such substances are also widely used in cosmetics and food packaging.
The Endocrine Society, which represents more than 18,000 doctors who treat hormone disorders, says it fully supports the new EPA proposal. It explains that these substances, also known as endocrine-disrupting chemicals, “do not break down when they are released into the environment, and they continue to accumulate over time. They pose health dangers at incredibly low levels and have been linked to endocrine disorders such as cancer, thyroid disruption, and reproductive difficulties.”
