    Notes: Abstract Acute suppurative thyroiditis is a rare disease, particularly in childhood. We present a case with recurrent acute suppurative thyroiditis due to a pyriform sinus fistula originating from the fourth branchial pouch. The typical symptoms of a piriform sinus fistula are recurrent left-sided pain and swelling of the neck with signs of acute bacterial inflammation. Diagnosis should be made by high resolution ultrasound, barium meal studies and endoscopic examination. During acute exacerbations treatment with antibiotics is indicated, but permanent cure can only be attained by complete fistulectomy.

    Acute renal transplant rejection in children: assessment by Duplex Doppler sonography (1988)
    Springer
    Pediatric radiology 18 (1988), S. 474-478

    Notes: Abstract Over a two year period 74 consecutive Duplex Doppler scans were performed in 23 children with renal allografts and were compared to the Doppler sonographic findings in orthotopic kidneys of 25 age matched healthy controls. The Doppler waveforms of renal arterial flow were analysed qualitatively assessing systolic and diastolic flow amplitudes, for quantitation the Pourcelot index (PI) was used. There was no variation between the Doppler waveforms in recipients with normal allograft function and healthy controls. In 12 patients with biopsy proven acute rejection a decrease or absence of the diastolic flow amplitude was noted, resulting in increased pulsatility of the Doppler wave-form. The mean PI in acute rejection differed significantly from the mean PI in normal allograft function. Duplex Doppler sonography is a useful imaging modality in the differentiation between acute rejection and normal allograft function and should therefore be integrated in the screening of children after renal transplantation.

    Portal venous blood flow in cystic fibrosis: assessment by Duplex Doppler sonography (1989)
    Springer
    Pediatric radiology 19 (1989), S. 371-374

    Topics: Medicine
    Notes: Abstract Changes of portal venous hemodynamics were investigated in 32 patients with cystic fibrosis (CF) with a mean age of 11.6 years. Hepatic profile of these patients included total bilirubin and albumin together with determination of size and echogenicity of the liver and spleen, determination of the diameter of the portal vein by real-time sonography and quantitation of flow volume of the portal vein using Duplex Doppler sonography. As a control, 35 age matched healthy children were also examined. Diameter of the portal vein was significantly increased in CF patients versus controls. Comparison of the mean flow volume of the portal vein showed a significant increase in CF-patients over 12 y old versus controls. In patients less than 12 y no significant difference of flow volume of the portal vein between CF-patients and controls was noted. The increase of diameter and flow volume of the portal vein suggest an adaptive mechanism in the pressure-volume relationship of the portal venous system in patients with CF.

    Cerebral blood flow in newborn infants with and without mechanical ventilation (1989)
    Springer
    Pediatric radiology 19 (1989), S. 509-512

    Notes: Abstract The influence of mechanical ventilation with low mena airway pressure (MAP) on cerebral blood flow (CBF) veolocity in newborn infants was assessed in fifteen ventilated infants by Duplex Doppler Sonography (Duplex DS). As a control, CBF velocities were examined in 15 age and weight matched non-ventilated infants. For quantitation, maximal systolic velocity, enddiastolic velocity and the semiquantitative Pourcelot index were determined as representative flow variables. There was no significant difference of these flow variables between ventilated and non-ventilated infants. The pH, pO2 and pCO2 did not differ significantly between the two groups and there was no correlation between the flow variables, pH, pO2, pCO2 or MAP. Mechanical ventilation with low MAP is not associated with adverse effects on cerebral hemodynamics in newborn infants when significant alterations of the blood gases are avoided.

    Disappearance of bowel gas in newborn infants on mechanical ventilation (1982)

    Topics: Medicine
    Notes: Abstract Loss of bowel gas was observed in 18 out of 49 neonates on mechanical ventilation (37%). Its occurrence was correlated to the outcome and to the use of sedative or neuromuscular paralysing drugs. None of the babies had gastrointestinal disorders requiring surgical intervention. A gasless abdomen was found in 6 out of 26 surviving neonates (23%) and in 12 out of 23 neonates (52%) not surviving the respiratory illness. Absence of intestinal gas in unsedated or unparalysed babies (23%) as well as in Alodan® treated babies (19%) was found with nearly equal frequency whereas its occurrence after neuromuscular paralysation with Alloferin® was significantly higher (91%). Disappearance of intestinal gas pattern despite, normal gastrointestinal patency, occurring in mechanically ventilated neonates severely affected by respiratory distress of varying origin or after neuromuscular drug paralysation should be recognized.

    Sonographic detection of internal jugular vein thrombosis after central venous catheterization in the newborn period (1994)
    Springer

    Details

    Topics: Medicine
    Notes: Abstract We sonographically investigated the internal jugular veins of 40 children who had undergone catheterization of the vein (group A: silastic catheter,n-24; group B: polyurethane catheter,n=16) in the neonatal period. The average age at catheter implantation was 43±73 days, the average birthweight 2414±1145 g, and the average gestational age 34.8±5.0 weeks. We performed follow-up longitudinal and transverse high resolution sonographic scans including routine examination of the contralateral jugular vein at a mean age of 3.7±1.5 years. In group A thrombotic alterations were detected in 8 aut of 24 patients. In three of these patients we found mild clinical symptoms. In group B thrombotic alterations were detected in 1 aut of 16 patients without clinical symptoms. Mean birthweight (1815 versus 3313 g) and mean gestational age (32.3 versus 38 weeks) were significantly lower and indwelling time of the catheters (18 versus 11 days) was significantly longer in group A. Our results indicate that jugular vein thrombosis is a frequent long-term complication in neonates after jugular vein catheterization. High resolution ultrasonography is an adequate method for detecting jugular vein thrombosis and should therefore routinely be performed for long-term follow-up.

    Notes: Abstract When using ultrasound for detection of kidney enlargement, we found an acute abdominal aortic aneurysm secondary to aortitis following umbilical artery catheterisation in a premature neonate with systemic candidiasis. Aortography was performed to provide vascular details such as involvement of celiac, renal, iliac and femoral arteries.

    Color-coded Doppler evaluation of cholecystic varices in portal hypertension (1990)
    Springer
    Pediatric radiology 21 (1990), S. 71-72 
    Details

    Topics: Medicine
    Notes: Abstract A 11-year-old white girl presented with a diagnosis of thrombosis of the portal vein after newborn septicemia. Duplex sonography revealed significant narrowing of the portal vein and its right and left branches. A Doppler signal could only be obtained in certain short segments of the portal vein and indicated hepatopetal flow. Color-coded Doppler sonography showed extensive varicose veins in the gallbladder with a bigger draining vessel running to the porta hepatis. Documentation of varices like those in the gallbladder wall confirms the diagnosis of portal hypertension and may increase the sensitivity of Doppler sonography. Color mapping has the potential to detect unexpected flow and to analyze blood flow to better advantage.
