We present two cases highlighting novel prenatal ultrasound findings in atretic cephalocele (AC) using high-resolution ultrasound and microvascular flow imaging. This report includes the first prenatal ultrasound demonstration of key diagnostic AC features: superior sagittal sinus fenestration, observed in the parietal case, and a fibrous dural stalk, identified in both parietal and occipital cases. Both fetuses presented with a small midline scalp lesion, internal echoes, and an underlying bony defect without brain tissue herniation.

Background: The m.3243A>G mutation in the MT-TL1 gene is the most common mtDNA mutation. The mutation can lead to a spectrum of conditions, including diabetes, hearing loss, heart and muscle involvement, encephalopathy and epilepsy, gastrointestinal problems, and vision impairment, often occurring concurrently-collectively referred to as MELAS (mitochondrial encephalopathy lactic acidosis and stroke-like episodes) syndrome.

This paper presents a semi-analytical method, referred to as the linear-velocity-profile fast field program (LFFP), for predicting two-dimensional sound fields in ambient parallel mean flows. The proposed method incorporates the linear velocity layering method into the fundamental framework of fast field program (FFP) to achieve reduced computational costs and enhanced precision, particularly under high-velocity gradient conditions. The accuracy of LFFP is validated through a two-dimensional jet case by comparison with the linearized Euler equation in frequency-domain.

Introduction: Syphilis in pregnancy, caused by Treponema pallidum, can be vertically transmitted, leading to serious neonatal complications such as preterm birth, stillbirth, and neonatal death. Despite global efforts to reduce its prevalence, challenges such as inadequate antenatal screening and delayed treatment persist. Early diagnosis and treatment are crucial to preventing adverse outcomes.
