Mitigating multiples, less is more: examining trends in multifetal gestation rates with assisted reproductive technology.

Purpose: Multifetal gestation (MFG) is much more common in pregnancies that utilize assisted reproductive technologies (ART). We assessed how these rates have changed over the previous decade and the impact on live birth rates (LBR).

Methods: This retrospective cohort study uses the National Summary Reports of the Society for Assisted Reproductive Technology (SART) from 2014 to 2020.

Progesterone Hypersensitivity: The Utility of a Janus Kinase Inhibitor for Recurrent Erythema Multiforme.

Background: Progestogen hypersensitivity (PH) is a rare phenomenon reported in women with an immunologic response to rising progesterone levels in the luteal phase. This disease's rarity and clinical spectrum make it challenging to diagnose.

Case: In this case report, we will discuss a 14-year-old female with monthly oral mucositis and palmar lesions consistent with erythema multiforme.

Appendectomy in pediatric patients with synchronous oncologic diagnosis is safe: an analysis using the national surgical quality improvement project, pediatric.

Background: Optimal treatment of children who develop appendicitis while undergoing treatment for an oncologic diagnosis has not been defined, in part due to theoretical concerns for an increased risk of postoperative wound complications. We hypothesized that synchronous oncologic diagnosis conferred no increased odds of developing a wound complication in pediatric patients undergoing appendectomy.

Methods: Retrospective cohort study using the National Surgical Quality Improvement Program, Pediatric (2012-2017) of patients < 18 years of age undergoing appendectomy.
