Revisiting the association between endometriosis and bipolar disorder.
We sought to study the association between endometriosis and bipolar disorder. ⋯ There may be an association between endometriosis and bipolar disorder. An optimal approach to managing endometriosis should include evaluation and treatment of psychiatric comorbidity, particularly bipolar disorder.

Comparative StudyPlanned caesarean hysterectomy versus "conserving" caesarean section in patients with placenta accreta.
Invasive placentation (placenta accreta, increta, or percreta) presents significant challenges at Caesarean section. Caesarean hysterectomy in such circumstances may result in massive blood loss despite surgical expertise. We reviewed two divergent surgical approaches: planned Caesarean hysterectomy versus a "conserving surgery" in which the placenta is left in situ after Caesarean section. ⋯ An initial conserving surgical procedure is an option in patients with extensive invasive placentation, but it requires further monitoring for potential complications and carries a high subsequent hysterectomy rate.

ReviewUse of a DNA method, QF-PCR, in the prenatal diagnosis of fetal aneuploidies.
To provide Canadian health care providers with current information on the use of quantitative fluorescent polymerase chain reaction (QF-PCR) or equivalent technology in the prenatal diagnosis of fetal chromosomal abnormalities. ⋯ This guideline promotes the use of a rapid aneuploidy DNA test for women at increased risk of having a pregnancy affected by a common aneuploidy. This will have the benefit of providing rapid and accurate results to women at increased risk of fetal Down syndrome, trisomy 13, trisomy 18, sex chromosome aneuploidy or triploidy. It will also promote better use of laboratory resources and reduce the cost of prenatal diagnosis. However, a small percentage of pregnancies with a potentially clinically significant chromosomal abnormality will remain undetected by QF-PCR but detectable by conventional cytogenetics. Recommendations 1. QF-PCR is a reliable method to detect trisomies and should replace conventional cytogenetic analysis whenever prenatal testing is performed solely because of an increased risk of aneuploidy in chromosomes 13, 18, 21, X or Y. As with all tests, pretest counselling should include a discussion of the benefits and limitations of the test. In the initial period of use, education for health care providers will be required. (II-2A) 2. Both conventional cytogenetics and QF-PCR should be performed in all cases of prenatal diagnosis referred for a fetal ultrasound abnormality (including an increased nuchal translucency measurement > 3.5 mm) or a familial chromosomal rearrangement. (II-2A) 3. Cytogenetic follow-up of QF-PCR findings of trisomy 13 and 21 is recommended to rule out inherited Robertsonian translocations. However, the decision to set up a back-up culture for all cases that would allow for traditional cytogenetic testing if indicated by additional clinical or laboratory information should be made by each centre offering the testing according to the local clinical and laboratory experience and resources. (III-A) 4. Other technologies for the rapid detection of aneuploidy may replace QF-PCR if they offer a similar or improved performance for the detection of trisomy 13, 18, 21, and sex chromosome aneuploidy.
