Postpartum endometritis is a common complication of cesarean section, the progression of which often leads to the loss of the uterus and the patient's fertility. We evaluated a detoxification therapy for treating patients with postpartum endometritis using an intrauterine application of a modified molded sorbent containing polyvinylpyrrolidone. A retrospective, controlled study included 124 patients with postpartum endometritis.

Article Synopsis
  • HtrA1 is a serine-protease protein expressed in various tissues, particularly the placenta, and its levels are higher in early pregnancy, indicating a potential role in placental development and gestational diabetes (GDM).
  • A study analyzed HtrA1 serum levels during both the first (10-12 weeks) and third trimesters (36-40 weeks) in women, comparing normal pregnancies to those with GDM.
  • Results showed that higher HtrA1 levels were linked to GDM both in the third trimester and as an early indicator in the first trimester, suggesting HtrA1 could serve as an effective marker for predicting GDM.

How to Manage Low Estriol Levels in Pregnancies, One Center Experience.

Medeni Med J

March 2022

University of Health Sciences Turkey, Basaksehir Cam and Sakura City Hospital, Clinic of Obstetrics and Gynecology, Division of Perinatology, Istanbul, Turkey.

Objective: Low estriol (uE3) levels in the second-trimester screening for Down syndrome may be the result of fetal demise, congenital abnormalities, or some genetic hormonal disorders of the fetus. Although X-linked ichthyosis, a microdeletion syndrome with mild ichthyosis, which causes steroid sulfatase (STS) deficiency, is the most common genetic cause, second-trimester screening tests calculate the risk for a less common and severe disorder known as the Smith Lemli Opitz syndrome (SLOS). We aimed to investigate the outcomes of pregnancies with low uE3 levels in Down syndrome screening and emphasize the high prevalence of STS deficiency instead of SLOS in such cases.

Article Synopsis
  • The study compared maternal serum midkine levels in pregnant women with different types of diabetes mellitus (DM) to those in healthy pregnant women.
  • Results showed that serum midkine levels were significantly higher in the DM group, especially in gestational diabetes mellitus (GDM) compared to Type 1 and Type 2 DM.
  • Despite the higher midkine levels in the DM group, the study concluded that serum midkine levels did not effectively predict adverse neonatal outcomes.

Purpose: IL-33 is associated with invasion, proliferation, and metastasis of various cancers. The trophoblastic cells of placenta previa accreta (PPA) invade into the myometrium in a similar way to the invasion of cancers. We studied the role of IL-33 in PPA and also aimed to investigate its relation with adverse maternal outcome in this placental disorder.
