Intrapartum Factors Affecting Abnormal Lipid Profiles in Early Postpartum Period.

The aim of this research is to investigate the risk factors during pregnancy affect abnormal lipid profiles in women with early postpartum period. This was a single-center retrospective study including 869 women who delivered between December 2017 and May 2019. We collected total cholesterol levels, both at 24-28 GWs and 1 month before delivery. Lipid profiles such as total cholesterol, high-density lipoprotein (HDL), triglyceride (TG) and low-density lipoprotein (LDL) at 6 weeks after delivery were retrieved. Subjects were categorized into 3 groups such as normal, borderline and abnormal group according to the lipid profile levels. The risk factors associated with borderline to abnormal HDL level were body mass index (BMI) of pre-pregnancy (OR = 1.182, 95% CI: 1.116-1.252, p < 0.001), weight gain during pregnancy (OR = 1.085, 95% CI: 1.042-1.131, p < 0.001) and hypertension (HTN) (OR = 3.451, 95% CI: 1.224-9.727, p = 0.02). The risk factors associated with borderline or abnormal TG were BMI of pre-pregnancy, weight gain during pregnancy and weight reduction after delivery. HTN was associated with borderline to abnormal TG in postpartum (OR = 2.891, 95% CI: 1.168-7.156, p = 0.02), while GDM correlated purely with abnormal TG in postpartum (OR = 2.453, 95% CI: 1.068-5.630, p = 0.03). Abnormal lipid profiles in postpartum were significantly associated with BMI of pre-pregnancy, weight gain during pregnancy and weight reduction after delivery. In addition, pregnancy-related HTN was highly associated with abnormal HDL level, and GDM was associated with abnormal TG level in the early postpartum period.

Prenatal Diagnosis of Uniparental Disomy in Cases of Rare Autosomal Trisomies Detected Using Noninvasive Prenatal Test: A Case of Prader-Willi Syndrome.

Rare autosomal trisomies (RATs) other than common aneuploidies can be detected using noninvasive prenatal testing (NIPT). However, conventional karyotyping is insufficient for evaluating diploid fetuses with uniparental disomy (UPD) due to trisomy rescue. Using the diagnostic process for Prader-Willi syndrome (PWS), we aim to describe the need for additional prenatal diagnostic testing for confirming UPD in fetuses diagnosed with RATs via NIPT and its clinical implications. NIPT was performed using the massively parallel sequencing (MPS) method, and all pregnant women with RATs underwent amniocentesis. After confirming the normal karyotype, short tandem repeat (STR) analysis, methylation-specific PCR (MS-PCR), and methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) were performed to detect UPD. Overall, six cases were diagnosed with RATs. There was a suspicion of trisomies of chromosomes 7, 8, and 15 in two cases each. However, these cases were confirmed to have a normal karyotype using amniocentesis. In one of six cases, PWS caused by maternal UPD 15 was diagnosed using MS-PCR and MS-MLPA. We propose that in cases where RAT is detected by NIPT, UPD should be considered following trisomy rescue. Even if amniocentesis confirms a normal karyotype, UPD testing (such as MS-PCR and MS-MLPA) should be recommended for accurate assessment, as an accurate diagnosis can lead to appropriate genetic counseling and improved overall pregnancy management.

Association between Successful Palpation of the Cricothyroid Membrane and the 3-3-2 Rule for Predicting Difficult Airway in Female Patients Undergoing Non-Neck Surgery: A Prospective Observational Cohort Study.

Background: Prediction of difficult airway is important for airway management in patients undergoing surgery. The assessment of airway structures and establishment of protective airway strategies are essential to improve patient safety. However, the association between successful palpation of the cricothyroid membrane and airway predictions has not been fully elucidated in patients undergoing surgery. We investigated this in female patients undergoing non-neck surgery. Methods: A total of 68 female patients were enrolled in this prospective observational cohort study between January 2021 and June 2021 at Eunpyeong St. Mary's Hospital, College of Medicine, Catholic University of Korea, Seoul, Republic of Korea. Exclusion criteria were male patients and those with neck pathology or neck surgery. The assessment of difficult airway was performed before the induction of anesthesia and was defined by one of the following conditions: inter-incisor distance < 3 fingerbreadths, hyoid-to-mental distance < 3 fingerbreadths, and thyroid-to-hyoid distance < 2 fingerbreadths (the "3-3-2 rule"). The accuracy of palpable identification of the cricothyroid membrane was confirmed by ultrasonography (US). The patients were divided into the non-difficult airway (NDA) group (n = 30) and the difficult airway (DA) group (n = 30). Results: The two groups were comparable in terms of age, but the DA group had higher body mass index (BMI). In airway assessment, 9 patients showed inter-incisor distance < 3 fingerbreadths, 3 patients showed hyoid-to-mental distance < 3 fingerbreadths, and 24 patients showed thyroid-to-hyoid distance < 2 fingerbreadths in the DA group. The rate of successful palpation of the cricothyroid membrane was higher in the patients without than in those with difficult airway variables. Conclusions: Patients with a positive 3-3-2 rule showed a poor palpability of cricothyroid membrane.

Currarino syndrome in an adult woman.

Currarino syndrome is a hereditary disease characterized by the triad of sacral agenesis, anorectal malformation, and presacral mass. Most patients are diagnosed in childhood, and this condition rarely manifests in adulthood. In women, gynecological malformations associated with Currarino syndrome have been reported, such as bicornuate uterus, rectovaginal fistula, and septate uterus. We present a rare case of a 29-year-old woman with a suspected pelvic mass who was diagnosed with Currarino syndrome.

Clinical outcome of high-grade cervical intraepithelial neoplasia during pregnancy: A 10-year experience.

OBJECTIVE: To investigate the clinical outcome of high-grade cervical intraepithelial neoplasia (CIN) diagnosed by colposcopy-directed biopsy during pregnancy and to evaluate the risk factors for persistent disease. STUDY DESIGN: This retrospective study included pregnant women who were diagnosed with CIN2+ by colposcopy-directed biopsy from January 2005 to December 2014. The clinical characteristics, histopathologic results, and human papillomavirus (HPV) test results were reviewed. The final histopathologic result after delivery was compared with the initial diagnosis to determine disease progression, persistence, or regression. RESULTS: During the 10-year period, 215 pregnant women were diagnosed with high-grade CIN (75 CIN2, 140 CIN3) by colposcopy-directed biopsy. The mean age of the patients was 30.4 years. A total of 187 patients (87.0%) had high-risk HPV infections, with 76 (35.3%) infections identified as HPV genotype 16 or 18. Excisional procedures for diagnosis and treatment were not performed during pregnancy. The histopathologic results of 160 patients (normal in 43, CIN1 in 10, CIN2 in 15, CIN3 in 89, and invasive cancer in 3) were evaluated during the postpartum period. Multivariate logistic regression analysis was performed, and postpartum high-risk HPV infection (OR 5.09; 95% CI 2.15-12.05; P < 0.001) was identified as a significant independent predictor of CIN2+ persistence. CONCLUSIONS: Conservative management of CIN2-3 during pregnancy is acceptable. However, persistent high-risk HPV infection is a major risk factor for CIN2+ persistence. Close follow-up with HPV testing, and postpartum colposcopy evaluation are necessary.
