What's new in obstetrics and gynecology from UpToDate

35% of UpToDate topics are updated every four months. The editors select a small number of the most important updates and share them via "What's new" page. I selected the brief excerpts below from What's new in obstetrics and gynecology:


Influenza vaccination with inactivated vaccine is recommended for pregnant women, regardless of the stage of pregnancy. The 2010-2011 influenza vaccine is trivalent and includes antigens from both the 2009 pandemic H1N1 influenza virus and seasonal influenza viruses.

Use of acetaminophen during pregnancy was associated with a reduction in neural tube defects, as well as cleft lip/palate and gastroschisis. These data support the safety of acetaminophen for relief of fever and pain.


Like CA 125, human epididymal secretory protein E4 (HE4) is a promising biomarker for ovarian cancer. In contrast to CA 125, HE4 levels do not appear to be elevated in women with endometriosis, and thus can be useful to rule out ovarian cancer in patients with endometriosis and a pelvic mass suspected to be an endometrioma.

Sterilization does not impact sexual function. Sexual function appears to be unchanged or improved in women following tubal sterilization.

Botulinum toxin may be useful for overactive bladder syndrome (onabotulinumtoxinA, Botox®). Detrusor injection of botulinum toxin (BoNT) had a transient effect. The average time between injections was 8 to 12 months.
