    Hyaline membrane disease in the newborn: Diagnosis by ultrasound (1990)
    Springer
    Pediatric radiology 20 (1990), S. 143-146

    Notizen: Abstract The authors report a new method of diagnosing hyaline membrane disease (HMD) in newborns: ultrasound. Babies with HMD display a specific pattern with retrohepatic hyperechogenicity on abdominal ultrasound. The specificity of the pattern was verified in 40 prematures with respiratory distress syndrome. The sign was present in 24, and in 22 of these the final diagnosis was moderate or marked HMD. In the last 2, mild HMD was suggested. The pattern was absent in the 16 others, none of whom had HMD. The pattern probably results from an ultrasound artifact: summation of multiple aerated airways surrounded by collapsed alveoli. Follow-up examinations were possible in 13 babies with HMD. Hyperechogenicity disappeared in 8 of these patients within 6–9 days and in 3 within 10–20 days; it persisted for 60 and 70 days in 2 with bronchopulmonary dysplasia. In conclusion, retrohepatic hyperechogenicity in newborns is pathognomonic for HMD and allows an instant diagnosis. The persistence of the pattern could be a useful criterion for evaluation of the prognosis.

    Atypical and equivocal sonographic features of the spinal cord in neonates (1995)

    Notizen: Abstract Thanks to the wider use of sonography to examine the spinal content in the neonate, normal anatomy and anomalies may be detected easily. Yet, unusual sonographic patterns are also observed. These must be differentiated from true pathologies. During a prospective study of 103 neurologically asymptomatic neonates, atypical sonographic patterns were found in 16 patients, corresponding to normal variants in 13. Nine of these 13 patients presented with a widening of the distal part of the central echo complex (one had a dilated ventriculus terminalis). Nerve roots of the cauda equina were disposed asymmetrically in three patients; the spinal cord movements were still present. In two of these babies, this distribution was associated with thin arachnoid pseudocysts. One patient presented with transitorily hyperechoic and narrow subdural spaces, probably related to neonatal dehydration. None of the 13 patients showing normal variants required any treatment. The other 3 patients (of 16) presented with equivocal entities of unknown evolution: sonographic tethered cord, fibrolipoma of the filum terminale and epidural varices. Sonography is highly accurate in evaluating the spinal cord content and aids differentiation of normal and normal variants from equivocal or pathological entities.

    Pulmonary sequestration-like anomaly presenting as a spontaneously resolving mass (1991)
    Springer
    Pediatric radiology 21 (1991), S. 143-144 
    Details
    ISSN: 1432-1998

    Thema: Medizin
    Notizen: Abstract A premature baby boy presented at birth with respiratory distress. A right lower lobe opacity was found on chest X-ray. Pulmonary sequestration was the diagnosis suggested by ultrasound. The size of the mass decreased on subsequent examinations. 4 months later X-rays and sonography failed to demonstrate any remaining mass. This case illustrates another example of involutive pathology and suggests that not all pulmonary sequestration-like anomalies should be operated on.

    Pericholecystic hyperechogenicities in necrotizing enterocolitis: A specific sonographic sign (1991)
    Springer

    Notizen: Abstract The authors report a new sonographic pattern found in association with neonatal necrotizing enterocolitis in 5 newborns: hyperechogenicities around the gallbladder. The pattern probably corresponds to extension of the disease to the perivesicular space. The most probable hypothesis for that extension is diffusion by contiguity through the lesser sac and/or the right gutter. The hyperechogenicities could be related to the foamy infiltrate typical of NEC. Air within the pericholecystic vascular system similar to portal air could be another (less probable) explanation.

    High-frequency ventilation and conventional mechanical ventilation in newborn babies with respiratory distress syndrome: A prospective, randomized trial (1993)

    Notizen: Abstract Objective Morbidity and mortality remain high amongst babies ventilated for a respiratory distress syndrome (RDS). Whether newly developed ventilators allowing high frequency ventilation such as high frequency flow interrupted ventilation (HFFIV) could decrease the morbidity and the mortality was investigated in a randomized study. Design Preterm babies weighing ≤1800g suffering from RDS and ventilated by conventional mechanical ventilation (CMV) were randomized to be further ventilated either by CMV (group CMV) or by HFFIV (group HFFIV) when peak inspiratory pressure (PIP) on CMV was ≥20cmH2O. Setting The study was undertaken in the neonatal intensive care unit of the Erasmus Hospital. Patients 24 patients entered into the investigation and were randomized but 2 patients were removed from the study because the switch over to HFFIV failed. Eight of the 12 CMV patients and 5 of the 10 HFFIV patients completed the study. Measurements and results Clinical variables, blood gas analysis and ventilatory variables were looked at. There were no differences in mortality, in incidence of air leaks and pulmonary complications or in blood gas analysis. Bronchopulmonary dysplasia was not decreased by the use of HFFIV. Conclusion It is concluded that HFFIV is safe although it offers no concrete advantages over CMV when applied as we did in a low pressure approach.

    Mapping of normal brain maturation in infants on phase-sensitive inversion-recovery MR images (1990)
    Springer
    Neuroradiology 32 (1990), S. 173-178

    Notizen: Summary It is illustrated that phase-sensitive inversion-recovery MR images are particularly well suited for the monitoring of brain maturation and myelination in the neonate and young infant. Provided appropriate timings are applied with the inversion-recovery MR pulse sequence, the myelinated areas show up as bright spots in the phase-sensitive images. The chronology of the appearance, and the location of these hyperintense zones correlate well with the chronology of brain maturation, as assessed by other means. In particular, the progressive functional capabilities of the infant correlate well with the progress of myelination, as exhibited by the MR images.
