Objective: The purpose of this study was to improve our understanding of severe serine biosynthesis defects through a comprehensive description of prenatal, and postnatal manifestations and the mutational spectrum in a new cohort of 12 unrelated Egyptian Families., Methods: Detailed fetal ultrasound examination, postnatal assessment, and whole exome sequencing (WES) were performed in a cohort of 12 fetuses with suspected Neu-Laxova syndrome (NLS), the most severe expression of serine biosynthesis defects. Additionally, a comprehensive review of the literature was conducted by merging the data from all the molecularly-confirmed cases with ours to gain a better understanding of the clinical variability of NLS., Results: Novel clinical manifestations including intrauterine convulsions, hemivertebrae, natal teeth, holoprosencephaly, and rhombencephalosynapsis were observed. Molecular analysis identified 7 and 2 likely disease-causing variants in the PSAT1 and PHGDH genes, respectively. Four of them were novel, including the c.734G>A missense variant in PSAT1, which has been proposed to be a founder variant among Egyptians., Conclusion: The present cohort expands the spectrum of serine biosynthesis disorders. Moreover, it illuminates the role of prenatal exome sequencing in lethal conditions constituting the most severe end of already-known human diseases., (© 2024 John Wiley & Sons Ltd.)

Background: Depo-medroxyprogesterone acetate (DMPA) functions as a contraceptive method by inhibiting the secretion of gonadotropins, which prevents follicular maturation and ovulation, as well as thinning of the endometrium leading to unscheduled vaginal bleeding and subsequent discontinuation of DMPA. Our study aimed to evaluate the efficacy and safety of clomiphene citrate (CC) in stopping bleeding among DMPA users., Materials and Methods: We randomly assigned 200 DMPA users using a computer-generated random numbers table in a 1:1 ratio to one of two groups; the study group, which received CC at a dose of 50 mg twice daily for five days (n = 100), and the control group, which received a placebo for five days (n = 100). Our primary outcome measure was the onset and duration of bleeding cessation. Secondary outcomes included endometrial thickness, recurrence of vaginal bleeding, and any reported side effects associated with CC use., Results: Clomiphene citrate significantly resulted in early cessation of vaginal bleeding in 83 % of the patients, which continued for three months of follow-up. In addition, the recurrence of vaginal bleeding was significantly reduced in the CC group compared to the control group (11 % vs. 67 %; p < 0.001). Endometrial thickness was significantly greater in the CC group than in the control group (p < 0.001). Breast tenderness was more frequently reported in the study group, with no difference in dyspareunia between the two groups., Conclusions: Clomiphene citrate is effective in controlling bleeding among DMPA users. Further studies are encouraged to confirm our findings., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Objective: Saline vaginal douching prior to intravaginal prostaglandin application might increase the vaginal pH, leading to improvement of prostaglandin bioavailability, by which the outcomes of labor induction can be greatly improved. Thus, we aimed to evaluate the effect of vaginal washing with normal saline before insertion of vaginal prostaglandin for labor induction., Study Design: A systematic search was done in PubMed, Cochrane Library, Scopus, and ISI Web of Science from inception to March 2022. We selected randomized controlled trials (RCTs) that compared vaginal washing using normal saline versus no vaginal washing in the control group before intravaginal prostaglandin insertion during labor induction. We used RevMan software for our meta-analysis. Our main outcomes were the duration of intravaginal prostaglandin application, duration from intravaginal prostaglandin insertion to active phase of labor, duration from intravaginal prostaglandin insertion till total cervical dilatation, labor induction failure rate, incidence of cesarean section (CS), and rates of neonatal intensive care unit (NICU) admission and fetal infection postdelivery., Results: Five RCTs were retrieved with a total number of 842 patients. Duration of prostaglandin application, duration from prostaglandin insertion to active phase of labor, and time interval from prostaglandin insertion to total cervical dilatation were significantly shorter among vaginal washing group ( p  < 0.05). Vaginal douching prior to prostaglandin insertion significantly decreased the incidence of failed labor induction ( p  < 0.001). After the removal of reported heterogeneity, vaginal washing was linked to a significant decline in CS incidence ( p  = 0.04). In addition, the rates of NICU admission and fetal infection were significantly lower in the vaginal washing group ( p  < 0.001)., Conclusion: Vaginal washing with normal saline before intravaginal prostaglandin insertion is a useful and easily applicable method for labor induction with good outcomes., Key Points: · Induction of labor is frequently used in the obstetrics field.. · We assessed vaginal washing impact before prostaglandin insertion for labor induction.. · Vaginal washing is an easily applicable method for labor induction with good outcomes.., Competing Interests: None declared., (Thieme.

Objective: To investigate the efficacy of vaginal probiotics administration in combination with prophylactic antibiotics versus antibiotic prophylaxis only on perinatal outcomes in women with preterm premature rupture of membrane (PPROM)., Methods: Four different databases were searched from inception till March 2023. We selected randomized controlled trials (RCTs) that compared vaginal probiotics along with antibiotics versus antibiotics only among pregnant women who were presented with PPROM between 24 and 34 weeks of gestation. We performed the meta-analysis using Revman software. Our primary outcomes were gestational age at birth and latency period duration. Our secondary outcomes were the rate of admission in the neonatal intensive care unit (NICU), infant birth weight, length of stay in the NICU, and neonatal complications., Results: Four RCTs, involving a total of 339 patients, were included in the meta-analysis. The gestational age at the time of delivery and latency period duration were significantly higher among probiotics + antibiotics group (p = 0.01 & p < 0.001). There was a significant reduction in the rate of NICU admission and length of NICU stay among the probiotics + antibiotics group compared to the antibiotics only group. A significant improvement in the infant birth weight after delivery was demonstrated among the probiotics + antibiotics group (p = 0.002). Although there was a decrease in the incidence of neonatal sepsis and respiratory distress syndrome within probiotics + antibiotics group versus antibiotics only group, these differences were not statistically significant (p > 0.05)., Conclusions: The combination of vaginal probiotics and antibiotic prophylaxis has been shown to effectively improve perinatal outcomes in women with PPROM. Further trials are needed to validate our findings., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.
