    Notes: Summary Cervical spinal cord lesions in the anterior spinal artery syndrome were delineated on magnetic resonance images (MRI) in four patients. The lesion was always seen anteriorly in the cervical cord. On T2-weighted images, the lesions appeared hyperintense relative to the normal spinal cord, while on T1-weighted images, two chronic lesions appeared hypointense, with local atrophy of the cord. In one case, repeated T1-weighted images showed no signal abnormality 4 days after the ictus, but the lesion became hypointense 18 days later, when contrast enhancement was also recognized after injection of Gd-DTPA; this sequence of intensity changes was similar to that of cerebral infarction. The extent of the lesion seen MRI correlated closely with neurological findings in all cases. Although the findings may not be specific, MRI is now the modality of choice for confirming the diagnosis in patients suspected of having an anterior spinal artery syndrome.

    Description / Table of Contents: Zusammenfassung Mittels Hochleistungs-Flüssigkeitschromatographie wurden durch Analyse der Fettsäuren in Sphingomyelien Adrenoleukodystrophien und Adrenomyeloneuropathien untersucht. Die oben erwähnte analytische Methode erwies sich als einfach, empfindlich und exakt. Bei der Adrenoleukodystrophie und bei Patienten mit Adrenomyeloneuropathie wurden sehr lange Fettsäureketten (C26:0, C25:0 und C24:0 auf der Basis von C22:0) sowohl in Plasma und den Erythrozytenmembranen als auch in Gesamtblutproben als vermehrt erkannt. Auch in Kulturen von Hautfibroblasten von Sphingomyelien wurde eine Zunahme der langkettigen Fettsäuren nachgewiesen. In einem Fall eines heterozygoten Adrenoleukodystrophiepatienten wurden Werte die zwischen jenen der homozygoten und der Kontrollfälle lagen gefunden. Somit ist die Hochleistungs-Flüssigkeitschromatographie eine brauchbare Methode, um eine Zunahme langkettiger Fettsäuren zwecks Diagnose einer Adrenoleukodystrophie oder einer Adrenomyeloneuropathie festzustellen.
    Notes: Summary Using high-performance liquid chromatography, adrenoleukodystrophy (ALD) and adrenomyeloneuropathy (AMN) were diagnosed by the analysis of fatty acids in sphingomyelin. The analytical method was simple, sensitive and accurate. In ALD and AMN patients, very long chain fatty acids (C26:0, C25:0 and C24:0 on the base of C22:0) were elevated not only in plasma and erythrocyte membranes but also in whole blood samples. An increase of long chain fatty acids was also shown in sphingomyelin of cultured skin fibroblasts. One heterozygote for ALD showed intermediate values between homozygotes and controls. Thus, high-performance liquid chromatography is a valuable method to detect increased long chain fatty acids for the diagnosis of ALD or AMN.

    Notes: Summary A patient with adrenoleukodystrophy and his mother, a carrier, showed an elevated ratio of very long-chain fatty acids to long-chain fatty acids and decreased beta-galactosidase activity. Other lysosomal enzyme activities were normal except for the borderline level of arylsulfatase-A activity. However, the father and other patients with variant forms of adrenoleukodystrophy showed normal beta-galactosidase and other lysosomal enzyme activities.
