    Description / Table of Contents: Summary An 11 weeks old boy was acutely ill with drowsiness, liver involvement with cholestasis and coagulopathy but normal ammonia levels. Despite repeated dicarboxylic aciduria we could not find enzymatic disorders of fatty acid oxydation. Persistent wheezy bronchitis and steatorrhea finally led to the diagnosis of cystic fibrosis, which was confirmed by sweat chloride test and genetic analysis. With intensive treatment of cystic fibrosis all the pathological findings vanished. Discussion: In conclusion, Reye-like syndromes and dicarboxylic aciduria in infancy may be the first signs of cystic fibrosis.
    Notes: Zusammenfassung Ein 11 Wochen alter Junge erkrankte akut mit Bewußtseinsstörung und Hepatopathie mit Cholestase und Gerinnungsstörung, allerdings normalen Ammoniakwerten. Trotz mehrfach nachgewiesener Dikarbonsäureausscheidung im Urin ließ sich kein Enzymdefekt im Fettsäureabbau nachweisen. Aufgrund einer zunehmenden Atemwegsobstruktion in Verbindung mit Fettstühlen wurde die Diagnose Mukoviszidose vermutet und mittels Schweißtest und Genanalyse bestätigt. Die intensive Therapie der Mukoviszidose führte zur raschen Normalisierung sämtlicher pathologische Befunde. Diskussion: Dieser Fall zeigt, daß bei Reye-ähnlichen Krankheitsbildern und einer Dikarbonsäureausscheidung im Säuglingsalter auch an eine Mukoviszidose gedacht werden muß.

    Notes: Summary It has been previously shown that the distances between the nuclei within the collagen bundles of mineralizing tissues were in good agreement with the repeat distances of the cross-banding pattern of collagen, which supports the assumption that the distances between the mineral deposits reflect to a good approximation the distances between nucleation centres on the collagen macromolecule. However, the lateral separation of the nuclei were significantly higher than the distances between close-packed triple helices. Recently a new model of collagen aggregation has been proposed in which the smallest morphological units are subfibrils (Ø approx. 39 Å) packed in tetragonal array. This led us to measure once again the lateral separation between a) close-packed calcium phosphate needles lying in bundles at (1) the mineralizing front of mantle dentine and (2) at the mineralizing front of rat tail bone, and b) between the uranyl-lead nuclei produced in the staining of rat tail tendon. The mean lateral distances separating these nuclei fell within the range of 39–47 Å, which is a little higher than the distances of 39 Å which separate the microholes between the subfibrils in the tetragonal packing model, which are regarded as the likely sites of nucleation. If, however, it is assumed that the forces generated during mineralization can cause the collagen fibres to swell, then the lateral separation of the nuclei and the distances between the microholes would correspond very closely.
