Objective: To evaluate the yield of work-up in intrauterine growth restriction (IUGR) pregnancies and their outcomes.

Materials And Methods: Retrospective data regarding prenatal work-up (serology, genetic testing and imaging), and neonatal outcomes of 198 IUGR pregnancies (estimated fetal weight <10th percentile) were analyzed.

Results: IUGR was isolated in 72 cases. Work-up performed in 158 (80%) cases was positive in 4 (2.5%). No abnormalities were detected in prenatal genetic testing. Echocardiogram performed in 27 cases was abnormal in 3 (11.1%). Serological testing performed in 150 pregnancies (75.8%) detected 1 case (0.7%) of cytomegalovirus (CMV) infection. Thirteen neonates (6.5%) were diagnosed with significant health problems. A positive work-up and significant postnatal health problems were not correlated with IUGR severity, symmetry or additional concurrent findings.

Conclusion: The yield of IUGR work-up is not clear and is probably highest for fetal echocardiography. The rate of significant adverse outcomes after birth is increased in IUGR pregnancies.

Background: Chromosomal numerical and structural alterations are significant causes of various developmental disorders in foetuses. Non-invasive prenatal testing (NIPT) has emerged as an effective screening tool for detecting common aneuploidies, aiding in the identification of individuals who may require further diagnostic work-up.

Methods: This retrospective, monocentric observational study evaluates the usage patterns, test choices, turnaround times (TAT), and outcomes of NIPT between 2013 and 2023 on a sample of 2431 pregnant women at a special hospital offering outpatient services and comprehensive gynaecological/obstetric inpatient care.

The Korean Huntington's Disease Society (KHDS) has recently published a practical guide for clinical approach to patients with Huntington's disease (HD) in Korea in April issue of Journal of Movement Disorders this year.1 This article is the second practical guide particularly focused on 1) essential points of genetic counseling for families of HD covering issues of testing minors and prenatal/preimplantation testing; and 2) premanifest HD and useful laboratory investigations for assessing disease severity and progression. The latter part of this article deals with special issues of juvenile and very late-onset HD, and common comorbidities in HD patients.

Introduction: Interstitial ectopic pregnancy is a rare but life-threatening condition, accounting for 2.4 % of all ectopic pregnancies. Diagnosing it can be challenging, as the interstitial portion of the fallopian tube allows for delayed rupture due to its capacity to expand, often leading to significant haemorrhage.

Congenital cytomegalovirus (cCMV) infection can lead to severe neurodevelopmental and hearing impairments. Imaging techniques can be used both pre- and postnatally to assess early signs of infection. The objective was to provide a systematic review of current literature regarding magnetic resonance imaging (MRI) and its value to predict clinical outcome in children with cCMV.

Background: Post natal adaptation syndrome is well reported but early presentation of neurological symptoms severe enough to warrant detailed neurological work up is rare. Our aim was to evaluate and describe abnormal early neurological symptoms in infants following in-utero exposure to a varying combination of selective serotonin uptake inhibitor medication and other psychotropic medications, with negative seizure work-up.

Method: Descriptive case series of infant exposed to selective serotonin uptake inhibitor medication and other psychotropic medications, presenting with early neurologic signs and symptoms within the first 24 hours of life concerning for seizures, who underwent an extensive neurologic evaluation.
