    Description / Table of Contents: Zusammenfassung Unter gewissen Voraussetzungen ist die Bestimmung der tryptischen, besonders aber der chymotryptischen Aktivität im Stuhl vor allem während der ersten 4–6 Lebenswochen als wichtige Maßnahme in der Diagnostik der Mucoviscidosis anzusehen. Nach Absetzen des Pankreasenzympräparates fällt die tryptische und chymotryptische Aktivität des Stuhles Mucoviscidosis-kranker Kinder ab. Nach Verabfolgung des Präparates steigt die Enzymaktivität in Abhängigkeit von der Höhe der Dosis an und erreicht die Aktivitätswerte altersentsprechender gesunder Kinder. Ein Vergleich zwischen der proteolytischen Aktivität und dem Fettgehalt des Stuhles im Rahmen von Untersuchungsperioden ohne Gabe des Pankreasenzympräparates und bei unterschiedlicher Dosierung des Präparates läßt eine signifikante Korrelation der beiden Parameter vermissen. Es ist nicht erlaubt, aus einer hohen proteolytischen Aktivität des Stuhles auf eine entsprechend verminderte Fettausscheidung zu schließen, da sich fäkale proteolytische Aktivität und Fettausscheidung nicht umgekehrt proportional zueinander verhalten. Man kann deshalb die Höhe der proteolytischen Aktivität im Stuhl von Mucoviscidosis-Patienten nicht als allgemeinen Maßstab für die gesamte Verdauungsleistung bei Pankreasenzymsubstitution betrachten.
    Notes: Abstract Under certain conditions the determination of the tryptic activity, especially of the chymotryptic activity in the feces mostly of infants in the first 4–6 weeks of life is considered to be an important step in the diagnosis of cystic fibrosis. The tryptic and chymotryptic activity in the feces of children with cystic fibrosis declines when the substitution of pancreatic enzymes is stopped. On resubstitution, the activity rises in relation to the dose and attains the activity related to age as found in healthy children. A comparison of the proteolytic activity with the fat content of the feces during the study period without the enzyme substitution and during the period when the enzyme dosage varied showed no significant correlation. It is not possible to postulate a poor excretion of fats merely from the high proteolytic activity of the feces because the fecal proteolytic activity and the fat excretion are not inversely proportional to one another. For this reason, one cannot conclude that the grade of the proteolytic activity in the feces of patients with cystic fibrosis is a yardstick for the total digestive process when they are under pancreatic enzyme substitution.

    Notes: Abstract  An 8-year-old boy was found to have primary moyamoya disease associated with a brain stem glioma. For over 3 years the child had experienced transient ischemic attacks induced by hyperventilation. One month before referral to our hospital he had presented with progressive left facial nerve palsy. Magnetic resonance imaging showed a cystic mass in the lower pons. Angiography revealed severe bilateral stenosis of the internal carotid arteries and prominent moyamoya vessels in the basal ganglia. Partial resection of the tumor yielded a histological diagnosis of pilocytic astrocytoma. Local radiation therapy reduced the size of the tumor. Anastomosis of the superficial temporal arteries and middle cerebral arteries on both sides was then performed. After direct bypass surgery, the patient remained in a good condition for a 5-year follow-up period. Clinical investigation of the coincidence of primary moyamoya disease and brain stem glioma led the authors to conclude that these two diseases coexisted independently.
