“…It is important to remember that 'color gain' is an operator dependent parameter in US, and it may be difficult to make the diagnosis of absence of blood flow in small vessels on color Doppler US. Although El Ayoubi et al [21] are credited by Shin et al [20] for generating a grading system in LSV based on blood flow, the evaluation of 70 patients with LSV by El Ayoubi et al did not include color Doppler analysis. Rather, grading was performed on the basis of the number of the 'streaks', and they used the terms minor, moderate and major to stratify their observations.…”

“…In another study that examined the longterm outcome, Shin et al [20] evaluated the relationship between the imaging patterns of the LSV and clinical outcomes. Of the 110 neonates included in the study group, 32 (29.1%) had evidence of LSV on cranial US, 22 had grade 1 and 10 grade 2 changes.…”

“…There does not appear to be a universal agreement in usage of the terms 'stage' [19] and 'grade' [20], yet they are likely used for the definition of the same observations. It is important to remember that 'color gain' is an operator dependent parameter in US, and it may be difficult to make the diagnosis of absence of blood flow in small vessels on color Doppler US.…”

“…The reported incidence of LSV ranges from 0.3% to 32%, depending on the population studied. [2][3][4] Because of the technological advances in cerebral ultrasound imaging and growing awareness among doctors of this cerebral ultrasound finding, the incidence of LSV identification has increased since the finding was first recognized. 2,5 The frequencies of transducers used for neonatal cerebral ultrasound 3 decades ago were 5-7.5 MHz, whereas the frequencies of contemporary neonatal cerebral ultrasound transducers range from 10 to 15 MHz, which greatly amplifies echogenicities within the cerebral tissue.…”

Neurodevelopmental Abnormalities in Children With In Utero Zika Virus Exposure Without Congenital Zika Syndrome

IMPORTANCEThe number of children who were born to mothers with Zika virus (ZIKV) infection during pregnancy but who did not have apparent disability at birth is large, warranting the study of the risk for neurodevelopmental impairment in this population without congenital Zika syndrome (CZS).OBJECTIVE To investigate whether infants without CZS but who were exposed to ZIKV in utero have normal neurodevelopmental outcomes until 18 months of age. DESIGN, SETTING, AND PARTICIPANTSThis cohort study prospectively enrolled a group of pregnant women with ZIKV in Atlántico Department, Colombia, and in Washington, DC. With this cohort, we performed a longitudinal study of infant neurodevelopment. Infants born between August 1, 2016, and November 30, 2017, were included if they were live born, had normal fetal brain findings on magnetic resonance imaging and ultrasonography, were normocephalic at birth, and had normal examination results without clinical evidence of CZS. Seventy-seven infants born in Colombia, but 0 infants born in the United States, met the inclusion criteria.EXPOSURES Prenatal ZIKV exposure. MAIN OUTCOMES AND MEASURES Infant development was assessed by the Warner InitialDevelopmental Evaluation of Adaptive and Functional Skills (WIDEA) and the Alberta Infant Motor Scale (AIMS) at 1 or 2 time points between 4 and 18 months of age. The WIDEA and AIMS scores were converted to z scores compared with normative samples. Longitudinal mixed-effects regression models based on bootstrap resampling methods estimated scores over time, accounting for gestational age at maternal ZIKV infection and infant age at assessment. Results were presented as slope coefficients with 2-tailed P values based on z statistics that tested whether the coefficient differed from 0 (no change). RESULTSOf the 77 Colombian infants included in this cohort study, 70 (91%) had no CZS and underwent neurodevelopmental assessments. Forty infants (57%) were evaluated between 4 and 8 months of age at a median (interquartile range [IQR]) age of 5.9 (5.3-6.5) months, and 60 (86%) underwent assessment between 9 and 18 months of age at a median (IQR) age of 13.0 (11.2-16.4) months. The WIDEA total score (coefficients: age = -0.227 vs age 2 = 0.006; P < .003) and self-care domain score (coefficients: age = -0.238 vs age 2 = 0.01; P < .008) showed curvilinear associations with age. Other domain scores showed linear declines with increasing age based on coefficients for communication (-0.036; P = .001), social cognition (-0.10; P < .001), and mobility (-0.14; P < .001). The AIMS scores were similar to the normative sample over time (95% CI, -0.107 to 0.037; P = .34). Nineteen of 57 infants (33%) who underwent postnatal cranial ultrasonography had a nonspecific, mild finding. No difference was found in the decline of WIDEA z scores between infants with and those without cranial ultrasonography findings except for a complex interactive relationship involving the social cognition domain (P < .049). The AIMS z scores were lower in infants with nonspecific cra...
