    Description / Table of Contents: Zusammenfassung Es werden Methoden dargestellt, mit denen eine quantitativ geringe Cystathioninausscheidung im Urin festgestellt und bewiesen werden kann. Es wurden 5 Kinder gefunden, die eine mäßige Cystathioninausscheidung aufwiesen (14,5–99,0 μMol/Tag). Die klinischen Befunde dieser Patienten werden dargestellt. Drei von ihnen hatten Leberaffektionen, eines eine nichtketotische Hyperglycinämie, und bei einem Kind handelte es sich um ein Neugeborenes mit multiplen Fehlbildungen. Bei allen Fällen lag eine sekundäre Cystathioninurie vor. Die Ursachen, die zu einer sekundären Cystathioninurie führen, werden besprochen.
    Notes: Abstract A secondary cystathionuria was found in two children with liver disease (cirrhosis of unknown etiology, congenital biliary atresia), in one infant with hypercalcemia due to high doses of vitamin D, in one case of non-ketotic hyperglycinemia, and in one infant with multiple malformations. Methods for the determination of cystathionine, when excreted in only small amounts, are outlined.

    Notes: Abstract The value of clinical parameters and umbilical arterial blood pH as indicator of prenatal hypoxia is disputed. In a prospective study of 86 vaginally delivered full-term infants, cardiotocographic (CTG) findings obtained 0–30 min and 30–60 min before birth were compared to pH values, O2 and CO2 partial pressures and glucose difference in umbilical arterial and venous blood. CTG findings were expressed as a score, higher values indicating fetal hypoxia. The venous but not the arterial blood pH was significantly related to the later (0–30 min) CTG score. The arterio-venous glucose difference was significantly related to both CTG scores. There was a significant statistical relationship between glucose difference and venous but not arterial blood pH. The later CTG score (0–30 min) also correlated significantly with O2 and CO2 partial pressures and base excess in the umbilical vein of all vaginally born infants. If CTG is accepted as an objective indicator of fetal hypoxia before birth, the arterio-venous glucose difference, and in the investigated range of pH-values, umbilical venous blood pH are more suitable than the arterial blood pH to ascertain the peripartal situation of the newborn.

    Notes: Abstract Metabolic studies in a case of Lesch-Nyhan syndrome are presented. De novo synthesis of purine was shown to be inhibited upon adenine administration. The excretion of oxypurines is elevated, however, by an increased incorporation of the administered adenine into purine bases. A side effect of adenine administration is the production of the slightly soluble and highly nephrotoxic 2,8-dioxyadenine, which can cause renal damage.
