    Additional value of advanced neurosonography and magnetic resonance imaging in fetuses at risk for brain damage
    (John Wiley & Sons, 2020) Van der Knoop, B. J.; Zonnenberg, I. A.; Verbeke, J. I. M. L.; De Vries, S.; Pistorius, L. R.; Van Weissenbruch, M. M.; Vermeulen, R. J.; De Vries, J. I. P.
    Objective: To assess the additional value of fetal multiplanar (axial, coronal and sagittal) neurosonography and magnetic resonance imaging (MRI) to that of the standard axial ultrasound planes in diagnosing brain damage in fetuses at high risk. Methods: This was a prospective, multicenter, observational study. Women were eligible for participation if their fetus was at risk for acquired brain anomalies. Risk factors were congenital infection, alloimmune thrombocytopenia, fetal growth restriction, trauma during pregnancy, fetal hydrops, monochorionic twins and prior ultrasound finding suggestive of an acquired brain anomaly. Examinations of the fetal brain before birth comprised axial ultrasound and advanced neurosonography biweekly and MRI once. After birth, neonatal cranial ultrasound was performed at < 24 h and at term-equivalent age. Neonatal brain MRI was performed once at term-equivalent age. An expert panel blinded to medical information, including imaging findings by the other methods, evaluated the presence of periventricular echogenicity (PVE) changes, peri- and intraventricular hemorrhage (IVH) and changes in basal ganglia and/or thalami echogenicity (BGTE) on ultrasound, and the equivalent signal intensity (SI) changes on MRI. Conclusions on imaging findings were generated by consensus. The children were followed up with examinations for psychomotor development at 1 year of age, using the Touwen examination and Alberta Infant Motor Scale, and at 2 years of age using Bayley Scale of Infant Development-III (BSID-III) and behavioral, sensory profile and linguistic questionnaires; scores > 1 SD below the mean were considered suspicious for neurodevelopmental sequelae. Results: Fifty-six fetuses were examined, and in 39/56 fetuses, all fetal-imaging modalities were available. PVE/SI changes were observed in 6/39, 21/39 and 2/39 fetuses on axial ultrasound planes, multiplanar neurosonography and MRI, respectively. IVH was found in 3/39, 11/39 and 1/39 fetuses, and BGTE/SI changes in 0/39, 12/39 and 0/39 fetuses, respectively. Outcome was suspicious for neurodevelopmental sequelae in 13/46 infants at 1 year, and at 2 years, 41/41 children had scores within 1 SD of the mean on BSID-III and 20 had scores > 1 SD below the mean on the behavioral (5/38), sensory profile (17/37) and/or linguistic (6/39) questionnaires. Conclusions: In this cohort of fetuses at risk for brain damage, the severity of acquired brain anomalies was limited. Nevertheless, multiplanar neurosonography detected more fetal PVE changes, IVH and/or BGTE changes compared to the standard axial ultrasound planes and MRI. Fetal MRI did not demonstrate any anomalies that were not seen on neurosonography. Neurodevelopmental outcome at 2 years of age showed no or mild impairment in most cases. © 2019 Authors.

    The Cape Triage Score : a triage system for South Africa
    (Health and Medical Publishing Group (HMPG), 2006-01) Wallis, L. A.; Gottschalk, S. B.; Wood, D.; Bruijns, S.; De Vries, S.; Balfour, C.; Cape Triage Group
    The Cape Triage Score (CTS) has been derived by the Cape Triage Group (CTG) for use in emergency units throughout South Africa. It can also be used in the pre-hospital setting, although it is not designed for mass casualty situations. The CTS comprises a physiologically based scoring system and a list of discriminators, designed to triage patients into one of five priority groups for medical attention. Three versions have been developed, for adults, children and infants. As part of the ongoing assessment process the CTG would value feedback from the readers of this Journal.

    Patterns of on-scene and healthcare system trauma deaths in the Western Cape of South Africa. World
    (John Wiley & Sons Ltd, 2024-02-03) Finn, J; Dixon, J.M.; Moreira, F.; Herbst, C.; Bhaumik, S.; Fleischer, C.L.; Stassen, W.; Beaty, B.; Lourens, D.; Verster, J.; Fosdick, B.; Lategan, H.J.; De Vries, S.; Uren, G.; Wylie, C.; Steyn, E.; Geduld, H.; Mould-Millman, N.-K.
    Background Injuries account for 8% or 4.4 million deaths annually worldwide, with 90% of injury deaths occurring in low- and middle-income countries. Inter-personal violence and road traffic injuries account for most injury deaths in South Africa, with rates among the highest globally. Understanding the location, timing, and factors of trauma deaths can identify opportunities to strengthen care. Methods This is a retrospective cross-sectional secondary analysis of trauma deaths from 2021 to 2022 in the Western Cape of South Africa. Healthcare system trauma deaths were identified from a multicenter study paired with a dataset for on-scene (i.e., prior to ambulance or hospital) trauma deaths in the same jurisdictions. We describe locations, timing, injury factors, and cause of death. We assess associations between those factors. Results There were 2418 deaths, predominantly young men, with most (2274, 94.0%) occurring on-scene. The most frequent mechanism of injury for all deaths was firearms (32.6%), followed by road traffic collisions (17.8%). On-scene deaths (33.2%) were significantly more likely to be injured by firearms compared to healthcare system deaths (23.6%) (p-value <0.01). Most healthcare system deaths within 4–24 h of injury occurred in a hospital emergency center. Among healthcare system decedents, half died in the emergency unit. Conclusions We identified a large burden of deaths from interpersonal violence and road traffic collisions, mostly on-scene. In addition to primary prevention, shortening delays to care can improve mortality outcomes especially for deaths occurring within 4–24 h in emergency centers.
