OBJECTIVE:  The timing of delivery for women affected by gestational diabetes (GDM) is still controversial. Good clinical practice often suggests offering induction of labor at term in order to reduce the complications associated with this condition, while recent evidence supports expectant management. Fetal Doppler parameters represent a validated tool for testing fetal well-being at term and can select pregnancies that need increased surveillance. The aim of the present study was to evaluate the role of fetal Doppler parameters at term for the prediction of pregnancy outcomes in patients affected by GDM...

In patients with idiopathic intracranial hypertension (IIH), transorbital sonography (TOS) may reveal an enlargement of the optic nerve sheath diameter (ONSD) and the presence of optic disc elevation (ODE), as a sign of an increase in intracranial pressure (ICP). We systematically reviewed the TOS findings in adults with IIH. MEDLINE, EMBASE, Cochrane Library and CENTRAL (1966 - May 2017) were searched to identify studies reporting data on patients with IIH assessed by B mode-TOS. Data were extracted and included in a meta-analysis, and the quality of the included studies was evaluated...

The diagnostic handling of benign focal liver lesions (FLLs) is a challenge and it is difficult to avoid over- and underdiagnosis. Conventional B-mode ultrasound and contrast-enhanced ultrasound (CEUS) are the first-line imaging methods to detect and characterize FLLs. This CME article discusses the diagnostic workup of benign liver tumors.

PURPOSE:  To assess the prognostic value of the wall shear stress (WSS) measured in the feeding native arteries upstream from facial superficial arteriovenous malformations (sAVMs). Reliable prognostic criteria are needed to distinguish progressive from stable sAVMs and thus support the indication for an aggressive or a conservative management to avoid severe facial disfigurement. MATERIALS AND METHODS:  We prospectively included 25 patients with untreated facial sAVMs, 15 patients with surgically resected sAVMs and 15 controls...

PURPOSE:  The human aorta stores strain energy in the distended wall during systole through the extracellular matrix of the tunica media that could be influenced by blood pressure, flow, or increased peripheral resistance. In intrauterine growth restriction (IUGR) fetuses, the increased aorta intima media thickness (aIMT) could reflect a different extracellular matrix composition and, therefore, functionality. The aim of this study was to analyze the resistance to flow in the fetal descending aorta and its relation to aIMT and systolic and diastolic fetal abdominal aorta diameters in IUGR fetuses and controls...
