ABSTRACT
Background@#The purpose of this study was to evaluate the effect of vanishing twin (VT) on maternal serum marker concentrations and nuchal translucency (NT). @*Methods@#This is a secondary analysis of a multicenter prospective cohort study in 12 institutions. Serum concentrations of pregnancy-associated plasma protein-A in the first trimester and alpha-fetoprotein (AFP), total human chorionic gonadotrophin, unconjugated estriol, and inhibin A in the second trimester were measured, and NT was measured between 10 and 14 weeks of gestation. @*Results@#Among 6,793 pregnant women, 5,381 women were measured for serum markers in the first or second trimester, including 65 cases in the VT group and 5,316 cases in the normal singleton group. The cases in the VT group had a higher median multiple of the median value of AFP and inhibin A than the normal singleton group. The values of other serum markers and NT were not different between the two groups. After the permutation test with adjustment,AFP and inhibin A remained significant differences. The frequency of abnormally increased AFP was also higher in the VT group than in the normal singleton group. @*Conclusion@#VT can be considered as an adjustment factor for risk assessment in the secondtrimester serum screening test.
ABSTRACT
Background@#People are generally considered overweight and obese if their body mass index (BMI) is above 25 kg/m 2 and 30.0 kg/m 2 , respectively. The World Health Organization proposed stricter criteria for Asians (≥ 23 kg/m2 : overweight, ≥ 25 kg/m2 : obese). We aimed to verify whether this criteria could predict adverse pregnancy outcomes in Korean women. @*Methods@#We included 7,547 Korean women from 12 institutions enrolled between June 2016 and October 2018. Women with no pre-pregnancy BMI data, not Korean, or lost to followup were excluded, leaving 6,331. The subjects were categorized into underweight, normal, overweight, class I obesity, and class II/III obesity based on a pre-pregnancy BMI of < 18.5, 18.5–22.9, 23.0–24.9, 25.0–29.9, and ≥ 30.0 kg/m2 , respectively. @*Results@#Overall, 13.4%, 63.0%, 11.8%, 9.1%, and 2.6% of women were underweight, normal, and overweight and had class I obesity and class II/III obesity, respectively. In the multivariable analysis adjusted for maternal age, a higher BMI significantly increased the risk of preeclampsia, gestational diabetes, preterm delivery caused by maternal-fetal indications, cesarean section, large for gestational age, and neonatal intensive care unit admission. @*Conclusion@#Adverse pregnancy outcomes started to increase in those with a pre-pregnancy BMI ≥ 23.0 kg/m2 after adjusting for maternal age. The modified obesity criteria could help predict adverse pregnancy outcomes in Koreans.
ABSTRACT
We report a 61-year-old woman with clinical course for Alzheimer’s disease (AD) dementia and discordant amyloid-β positron-emission tomography (PET) and cerebrospinal fluid biomarkers. Brain magnetic resonance imaging revealed remarkable atrophy in the hippocampus. However, repeated delayed 18F-flutemetamol brain amyloid PET images with 1 year-interval revealed no amyloid deposition, whereas her CSF revealed low Aβ42, high total tau and p-tau181. This discordant amyloid-β PET and CSF biomarkers in this early-onset AD dementia might be associated with her low resilience or mixed pathology.
ABSTRACT
We report herein a 78-year-old woman with insidiously progressive cognitive impairment and asymmetric amyloid deposition and neurodegeneration. Brain magnetic resonance imaging revealed remarkable atrophy in the right-sided temporal lobe and hippocampus. Early dynamic 18F-flutemetamol brain amyloid positron-emission tomography images showed decreased uptake in the right temporoparietal regions. Delayed images revealed amyloid deposition which was most remarkable in the right frontotemporoparietal regions. Asymmetries of amyloid burden and neuronal dysfunction are positively correlated in Alzheimer’s disease in cortical regions with high amyloid load.

ABSTRACT
Objective@#Early trauma (ET) is widely recognized as a contributing factor to the development of panic disorder (PD) in patients. However, there is a dearth of research on the specific volumes of hippocampal subregions and their laterality with respect to ET and PD. @*Methods@#A total of 30 subjects with PD and 30 age- and sex-matched healthy controls (HCs) were included in this study. All the subjects were evaluated by 3T-magnetic resonance imaging. FreeSurfer version 6.0 was used for volumetric analysis of the hippocampal subregions and their laterality. A shortened version of the Early Trauma Inventory Self Report (ETISR) as well as Anxiety Sensitivity Inventory-Revised (ASI-R), and Panic Disorder Severity Scale were utilized for analysis. @*Results@#Multivariate analysis of variance showed that the volume of the right hippocampal tail and laterality indices (LIs) of the hippocampal body and tail were significantly larger in subjects with PD relative to HCs. The significance of the observations remained unchanged after multivariate analysis of covariance, controlling for age, sex, years of education, medication, depressive symptoms, and intracranial volume as covariates. The LIs of the hippocampal tails that showed a significant correlation to ETISR emotional and physical subscales were also associated with ASI-R for cardiovascular symptoms in PD. @*Conclusion@#Our study displayed an increased rightward lateralization of the hippocampal tails in subjects with PD compared with HCs. This alteration in the brain, which was associated with early emotional and physical trauma, would negatively affect anxiety sensitivity to cardiovascular symptoms in subjects with PD.
ABSTRACT
Pyoderma gangrenosum is an extremely rare chronic cutaneous disease causing severe ulceration. It can be developed after minor trauma or surgical procedure. The typical features mimic acute infection site, however the treatment methods are opposing since pyoderma gangrenosum is improved with the use of corticosteroids, not antibiotic therapy. We here report a patient who had been diagnosed for acute infection after cesarean delivery in 2011 and treated with a number of antibiotics, but failed to recover. The patient had suffered from pain of the disease and also renal failure caused by antibiotics. Ultimately she had been diagnosed as pyoderma gangrenosum and managed successfully with steroids. For her next pregnancy in 2013, we tried vaginal delivery after prior cesarean section and it was uneventful during and after delivery.

Assisted reproductive technology (ART) is defined as any treatment and procedure associated with the handling of human oocytes, sperms or embryos for the purpose of establishing a pregnancy. As the use of ART has been dramatically increasing over 3 decades and the number of babies born by ART are increasing, it is important to consider perinatal outcomes of pregnancies with ART including structural abnormalities, growth and development, as well as the clinical pregnancy rate and the live-birth rate with regard to the parameters assessing the success of ART. Clinicians should be aware of maternal and perinatal outcomes in pregnancy with ART and infertile couples considering ART should be thoroughly counseled on these issues. In this article, the perinatal outcomes of pregnancy with ART will be reviewed.
