[THE DIFFERENTIAL DIAGNOSIS OF EXTREMELY HIGH MATERNAL SERUM ALPHA FETOPROTEIN - A CASE REPORT].

INTRODUCTION: A 34 years-old woman was referred to genetic counseling due to extremely high maternal serum alpha fetoprotein (MSAFP) of 58 MoM (541 IU/mL, 654 ng/mL) in the second trimester biochemical test. The couple has five healthy children, three of them were delivered by cesarean section. Current pregnancy follow-up was uneventful except for the demonstration of placenta percreta during anomaly scan. The test also ruled out neural tube or abdominal wall defect. AFP levels in amniotic fluid were normal thus fetal disease was ruled out as the etiology. Total body MRI ruled out space occupying lesion as a source of ectopic secretion of AFP. After exclusion of other ominous etiologies for this extremely high MSAFP, it was related to the placental pathology and probably to abnormal feto-maternal shunts. Fetal fraction in cell free DNA was 18%, considered relatively high, a hint for those speculated shunts. We reviewed the literature regarding the differential diagnosis of high MSAFP including fetal, maternal and placental sources.

Postpartum dyspareunia: clinical evaluation, causes, and treatment outcomes.

BACKGROUND: Dyspareunia affects approximately half of postpartum women and is attributed to multiple factors. Despite its high prevalence and resultant negative effects, data are lacking regarding the causes and different pain components, the usefulness of recommended treatments, and the prognosis. AIM: To evaluate causes of postpartum dyspareunia, targeted treatment modalities, and their effectiveness. METHODS: A retrospective observational study was conducted of women diagnosed with postpartum dyspareunia between September 2008 and January 2017 at a single designated vulvovaginal disorder clinic. The inclusion criterion was complaint of painful intercourse commencing postdelivery. The cohort was divided into 4 groups based on the causes of dyspareunia: muscle hypertonicity, scar tenderness, vestibular tenderness, and atrophy. OUTCOMES: The following were assessed for each group: patient background demographics, clinical and obstetric data, physical findings, recommended therapy, adherence to the suggested treatment, level of improvement at follow-up visits, and length of time until maximal improvement. RESULTS: A hundred women met the inclusion criterion; the majority (n = 60) presented with >1 causative factor. The most common finding was vestibular tenderness (n = 78, 78%), which was significantly associated with atrophy (adjusted odds ratio [aOR], 15.08; 95% CI, 2.45-93.35), contraceptive usage (aOR, 4.76; 95% CI, 1.07-21.39), and primiparity (aOR, 4.89; 95% CI, 1.01-23.88). Episiotomy was the only risk factor for scar tenderness (aOR, 5.43; 95% CI, 1.20-24.53), while the existence of a spontaneous perineal tear was not. No specific correlation was found with pelvic floor muscle hypertonicity. Targeted treatment resulted in significant improvement in most patients. CLINICAL IMPLICATIONS: A targeted diagnostic and treatment approach for postpartum dyspareunia is effective and can be beneficial for caregivers treating postpartum women. STRENGTHS AND LIMITATIONS: A uniform and consistent protocol for patient selection and management is a major strength, which magnifies the clinical implication of our findings. The retrospective nature of the study is the primary limitation. CONCLUSION: Postpartum dyspareunia is a common problem; however, many women refrain from discussing it with their providers. Therefore, it is important to assess this condition with all women during the postpartum visit as targeted diagnosis and treatment can significantly improve outcomes.

Boosting maternal and neonatal anti-SARS-CoV-2 humoral immunity using a third mRNA vaccine dose.

BACKGROUND: To minimize COVID-19 pandemic burden and spread, 3-dose vaccination campaigns commenced worldwide. Since patients who are pregnant are at increased risk for severe disease, they were recently included in that policy, despite the lack of available evidence regarding the impact of a third boosting dose during pregnancy, underscoring the urgent need for relevant data. We aimed to characterize the effect of the third boosting dose of mRNA Pfizer BNT162b2 vaccine in pregnancy. METHODS: We performed a prospective cohort study of anti-SARS-CoV-2 antibody titers (n = 213) upon delivery in maternal and cord blood of naive fully vaccinated parturients who received a third dose (n = 86) as compared with 2-dose recipients (n = 127). RESULTS: We found a robust surge in maternal and cord blood levels of anti-SARS-CoV-2 titers at the time of delivery, when comparing pregnancies in which the mother received a third boosting dose with 2-dose recipients. The effect of the third boosting dose remained significant when controlling for the trimester of last exposure, suggesting additive immunity extends beyond that obtained after the second dose. Milder side effects were reported following the third dose, as compared with the second vaccine dose, among the fully vaccinated group. CONCLUSION: The third boosting dose of mRNA Pfizer BNT162b2 vaccine augmented maternal and neonatal immunity with mild side effects. These data provide evidence to bolster clinical and public health guidance, reassure patients, and increase vaccine uptake among patients who are pregnant.

Boosting Dose of Pfizer-BioNtech mRNA Vaccine Against SARS-CoV-2 Does Not Affect Reproductive Outcomes in In-Vitro Fertilization Patients: A Cohort Study.

Background: Since the introduction of anti-COVID-19 mRNA vaccination, few studies have shown that reproductive outcomes in artificial reproductive technology (ART) treatments are not impaired, after receiving the two-dose regimen. Our aim was to investigate whether a boosting dose of the Pfizer-BioNtech mRNA vaccine affects reproductive outcomes in ART patients. Materials and Methods: This is a prospective observational study, including 157 consecutive in-vitro fertilization (IVF) cycles between October 1, 2021, and November 24, 2021, in a single university affiliated IVF unit. We included female patients going through an ART procedure and male partners in cases of utilization of a fresh sperm sample. The study population was divided into four groups according to exposure status: vaccinated and boosted patients (three total doses of Pfizer-BioNtech mRNA vaccine), patients who were vaccinated without the booster dose (one or two vaccine doses), PCR-confirmed convalescent COVID-19 patients, and unvaccinated nonconvalescent patients. Main outcome measure was clinical pregnancy rate. Results: In total, 99 (63%) female patients were vaccinated three times, 24 (15.3%) were vaccinated without the booster dose, 21 (13.4%) were convalescent, and 13 were (8.3%) unexposed. Although age differed between study groups, vaccination exposure status did not affect treatment outcome: clinical pregnancy rates, maximal estradiol levels, and number of oocytes retrieved did not differ significantly between study groups (p = 0.78, 0.50, and 0.97, respectively). Vaccinated patients who received a boosting vaccine dose were treated within 43.3 ± 30.9 days after receiving the last dose, whereas vaccinated, nonboosted, or convalescent patients were treated 168.7 ± 53 and 209.6 ± 85.1 days after their last exposure, respectively. We stratified the male cohort according to boosting vaccine dose status. Sperm concentration and motility did not differ significantly after boosting (p = 0.49 and 0.49, respectively). Conclusions: Our results provide further reassurance that IVF outcomes are not affected by the anti-SARS-CoV-2 Pfizer-BioNtech mRNA vaccine, in particular the three-dose regimen.
