Computed tomography in Krabbe's disease: comparison with neuropathology.

We report computed tomography (CT) appearance of two patients with Krabbe's disease. The most common findings included severe brain atrophy: an enlarged frontal extracerebral space, dilatation of ventricles, enlarged cisterns and enlarged cortical sulci. There was low attenuation in the corpus medullaris of the cerebellum, and symmetrical focal hypodensity in the central periventricular white matter. CT at the terminal stage (16 months) showed marked cerebral atrophy including flattening of the heads of caudate nuclei and widening of the third ventricles confirmed by a neuropathological study. There was relatively less low density on the white matter of Krabbe's disease compared with that of other leukodystrophies. These CT findings may be useful in the diagnosis. The relative lack of low density in the white matter of Krabbe's disease might be related to severe gliosis and reduced total lipid contents.

[Case report of lymphangioma--a review of benign non-epithelial tumors of the pancreas].

Benign nonepithelial growths from indigenous structures in the pancreas are extremely rare. A patient with a lymphangioma of the pancreas is reported and 18 cases with benign non-epitherlial tumors reported in the Japanese literature are discussed. Of 18 tumors, 7 were hemangiogenic, 5 were lymphagiogenic, 3 were neurogenic and one each was fibromatous, leiomyomatous and teratomatus. There was no particular association with sex and age. Frequent symptoms suggesting intraintestinal hemorrhage, i.e. tarry stool, melena, occult blood, anemia.

Radioimmunoassay of serum glycocholic acid, standard laboratory tests of liver function and liver biopsy findings: comparative study of children with liver disease.

Serum glycocholic acid (SGC) was measured by radioimmunoassay in 277 samples from 122 children with hepatobiliary disorders and from 23 healthy age-matched controls. In patients with hepatobiliary disease the SGC was more frequently abnormal (83%) than values for serum albumin (7%), prothrombin time (17%), bilirubin (22%), alkaline phosphatase (45%), aspartate transaminase (57%) and gammaglutamyl transpeptidase (63%). The cumulative frequency of abnormality of these six tests was equal to that of SGC alone. Serum glycocholic acid concentrations were raised in 13 patients in whom all other tests of liver function were normal. Two of these had clinical and histological evidence of liver disease, while four had biopsy-proven hepatic fibrosis or cirrhosis, and two of three with chronic active hepatitis in remission subsequently relapsed. Four patients have as yet, no other clinical or biochemical evidence of continuing liver disease. Serum glycocholic acid was normal in seven children with abnormal aspartate transaminase or gammaglutamyl transpeptidase in whom there is strong suspicion of significant hepatic disease. A wide range of values of SGC was found with marked overlap between the values found in the different disease entities studied. The SGC value was related to the serum concentration of aspartate transaminase and gammaglutamyl transpeptidase but not to other tests of liver function. Serum glycocholic acid concentration was considered in relation to the severity of histological abnormality in 25 percutaneous liver biopsies. The extent of the rise in SGC was related to the presence or degree of histological severity of oedema in the portal tracts, disruption of the limiting plate, parenchymal fibrosis and hepatocellular necrosis but not to other histological features. The very high incidence of abnormal SGC values found in this study does suggest that in an ordinary inpatient and outpatient service SGC determination is a practical and sensitive indicator of the presence of significant liver disease but for its comprehensive identification aspartate transaminase and gammaglutamyl transpeptidase must also be determined.

Clinicopathological differences between juvenile and late infantile metachromatic leukodystrophy.

The autopsy report of the juvenile type of metachromatic leukodystrophy is rare. The clinical and pathological difference between the juvenile and the late infantile type of metachromatic leukodystrophy was described. Loss of myelin sheaths was much less in the brain stem and spinal cord in the juvenile type than in the late infantile type, although that of the roots or cranial and spinal nerves was marked similarly in both types. The relationship of these pathological findings to clinical signs and laboratory data was discussed.

Alpha-fetoprotein in infantile obstructive jaundice in comparison with the normal ranges.

In an attempt to study the diagnostic value of alpha-fetoprotein (AFP), serum AFP concentrations were measured by radioimmunoassay in 34 neonates and infants with obstructive hepatobiliary diseases and the results were compared with the normal ranges of AFP at this age. Eighteen of 24 infants with biliary atresia and four of six infants with neonatal hepatitis had raised AFP values. In only one of four infants with choledochal cyst, did the AFP value exceed the normal range. In 10 older children with this lesion, AFP was normal. Serum AFP concentrations in biliary atresia did not correlate with the serum bilirubin, s-GOT, s-GPT, anatomic type of the lesion or postoperative bile flow. From these observations, it would appear that the elevation of AFP in infantile cholestasis is unrelated to underlying diseases except in case of alpha 1-antitrypsin deficiency. Serum AFP concentrations in neonates with physiological jaundice, were seldom elevated, and showed a good correlation with serum levels of total bilirubin. Possible mechanisms causing this elevation of AFP may be different from those involved in infantile cholestasis.

Clinical significance of specific IgE antibody against streptokinase-streptodornase in renal diseases of childhood.

The immediate skin reaction (IR) with streptokinase-streptodornase (SK-SD) was found with a high incidence in children with renal disease and was confirmed to be mediated by a specific IgE antibody against SK-SD by means of the radioallergosorbent test (RAST). This test revealed high radiocounts in children with renal disease who showed the IR and there was a close correlation between the RAST counts and the intensity of the IR. Furthermore, the RAST counts in the severe nephrotic syndrome belonging to corticosteroid dependent and resistant group were far higher than those in the corticosteroid sensitive group. From these results, a determination of the RAST counts against SK-SD seemed to help evaluate the severity of some nephrotic syndromes and the specific IgE antibody may be involved in the pathogenesis of the disease.
