Clinical heterogeneity in infantile galactosialidosis

A new case of infantile galactosialidosis is presented. The condition was diagnosed when the patient was 4 months of age and she died at 20 months. She exhibited some of the symptoms of classical infantile galactosialidosis but no corneal clouding, cherry-red macular spot or limitation of joint mobility. Sonographic examination showed large kidneys and thickened cardiac septa, two symptoms as yet undescribed in this disorder. Urinary oligosaccharide analysis gave grossly pathological results and subsequent fibroblast enzyme analysis showed a deficiency of alpha-neuraminidase and beta-galactosidase. The patient's clinical features are compared with the few cases so far described in the liter…

The diagnostic significance of cholescintigraphy and ultrasound examination in cholestatic syndromes in infancy

Thirty-three neonates and infants with cholestatic syndromes of various etiologies were evaluated by cholescintigraphy and ultrasound examinations. The results of these two diagnostic procedures were compared with the final diagnosis as confirmed by liver biopsy and/or laparotomy and the clinica follow-up of the infants. Fourteen patients had an obstructive cholangiopathy (11 biliary atresia, 2 choledochal cysts, 1 congenital choledochal stenosis), 13 had neonatal hepatitis, and 6 had cholestasis of another etiology. Typical ultrasonic and/or scintigraphic findings confirmed or excluded the need for surgical exploration in 28 patients. Thus, for must infants with cholestatic syndromes it is…

Sonographic biometry in obstructive uropathy of children: preoperative diagnosis and postoperative monitoring.

Renal sonography was performed in 92 children with obstructive uropathy or vesicoureteral reflux preoperatively and at follow-up. Renal volume and the anteroposterior diameter of the renal pelvis proved to be the most reliable morphometric criteria for objective sonographic staging and follow-up of urinary tract obstruction. If transient obstruction occurred after uncomplicated antireflux ureterovesico-plasties (n = 41), it lasted at most 4 weeks. Kidneys with transient postoperative ureterovesical junction obstruction (n = 21) reverted to normal sonographic pattern within 4 weeks following ureteral reimplantation. In cases of ureteropelvic junction obstruction (n = 30), it took up to 6 mon…

Sonographische Darstellbarkeit der Gallenwege und Beurteilbarkeit der Gallenblasenkinetik bei gesunden Neugeborenen

The gallbladder and the biliary tract of 85 neonates were sonographically examined, in the fasting state. The gallbladder was detectable in all neonates and showed a measurable contraction. Two types of biliary contraction could be observed: a concentric contraction of length, depth and width (concentric type) or a contraction of depth and width (collapse type). The grade of postprandial contraction was independent of the level of serum bilirubin. Furthermore, sonographic criteria were established allowing the differentiation of the bile ducts and their discrimination from hepatic arteries.

Sonographic biometry of liver and spleen size in childhood.

In 194 healthy children of all ages, sonographic measurements of the liver and spleen were performed on standardized section planes and normal values established. These measurement values showed an approximately linear increase in the course of development and correlated best with the body length. For a rapid orientational evaluation of the liver size, sonographic nomograms of the individual measurements were developed. The spleen size was determined by volume calculation. On the basis of an index of liver size, which was calculated from the individual measurements, a diagram for simultaneous determination of liver and spleen size could be developed. These nomograms permit objective morphom…

Sonographische Darstellbarkeit und Größenbestimmung von Abdominalorganen bei gesunden Neugeborenen

The determination of organ size is another important criterium in ultrasound examination. There are only few investigations in the neonatal group. Therefore in a prospective study the abdominal organs of 85 neonates were examined with a 7.5 MHz small part scanner. These organs were measured in standardized sections in order to establish normal values]
