Following a child playground equipment injury prevention project conducted in New York State in 1977, there was a 42 per cent reduction in playground equipment hazards, and a 22.4 per cent reduction in playground related injuries treated in the two largest hospitals of one of the program sites. Knowledge about unsafe playground practices and equipment hazards improved after the workshops for playground personnel. This approach to injury prevention deserves further study.

Pyomyoma, also known as suppurative leiomyoma, is a rare clinical complication that occurs when a leiomyoma undergoes infarction and subsequent infection. A high index of suspicion is required to make the diagnosis and can be guided by a classic triad of symptoms that includes abdominal pain, sepsis without an obvious source, and a history of leiomyoma. In the vast majority of these cases, total abdominal hysterectomy is required to avoid severe morbidity and potential mortality. We present an unusual case of a postpartum pyomyoma that was successfully treated without the need for hysterectomy. With strong clinical suspicion, early diagnosis, and appropriate management, some affected patients may preserve fertility.

What's Already Known About This Topic? Noninvasive prenatal screening (NIPS) has been shown to be a highly accurate tool for prenatal detection of aneuploidy, without risk to the fetus Less is the accuracy of NIPS for the detection of sex chromosome aneuploidies (SCAs) Reduced accuracy in diagnosis of SCA has been attributed to placental mosaicism It is probable that some false‐positive diagnoses of sex chromosome aneuploidy are because of abnormal maternal karyotype What Does This Study Add? This is a case of abnormal maternal karyotype that leads to a false‐positive result for fetal sex chromosome aneuploidy Two laboratories interpreted samples from the mother differently, with utilization of unique data analysis methods This underscores the importance of how NIPS results are reported and genetic counseling that must follow Caution is advised when acting upon positive results to avoid exposing fetuses to potentially harmful testing
