    Notes: Abstract The stimulatory effect of Nacom® (250 mg L-Dopa and 25 mg L-Carbidopa) on the HGH secretion was evaluated in 75 short stature patients. The number of blood samples was restricted to only three (0, 45 and 90 min). 63 patients reached adequate HGH concentrations after the ingestion of 1 tablet Nacom (84%). Somatotropin levels increased from 2.08 (S x 0.28) to a maximal HGH value of 14.22 (S x 0.87) ng/ml. When the stimulatory effect of Nacom was compared with the standard method of arginine infusion in children with normal stature the arginine test was not superior to the Nacom-test. The Nacom-test appears to be a simple and reliable screening method for HGH deficiency, particularly in outpatients.

    Description / Table of Contents: Zusammenfassung Bei Kindern ohne Minderwuchs im Alter von 6–14 Jahren wurde nach oraler Gabe von 250 mg Levodopa und 25 mg l-Carbidopa (Nacom, ein Kombinations-präparat) die Wachstumshormonkonzentration im Serum bestimmt. Alle Probanden zeigten einen ausreichenden Wachstumshormonanstieg. Der Mittelwert betrug 19,6 ng/ml. Nach dem Maximum der HGH-Konzentration ließen sich zwei Gruppen unterscheiden. Die eine Gruppe erreichte zum Zeitpunkt 20 bzw. 40 min, die andere nach 60 bzw. 90 min den stärksten HGH-Anstieg. Aufgrund des Verlaufs der Mittelwertskurve werden 2 Blutentnahmen, 40 und 90 min nach Einnahme des Präparates, zum Ausschluß eines Wachstumshormonmangels für ausreichend gehalten. Das wahrscheinlich zugrundeliegende Wirkungsprinzip der HGH-Sekretion durch l-Dopa und l-Carbidopa wird anhand der Literatur diskutiert.
    Notes: Abstract The stimulatory effect of l-Dopa and l-Carbidopa (Nacom) on HGH secretion was determined in 12 children of normal height aged from 6 to 14 years. Each child received a standard dose of 250 mg l-Dopa and 25 mg l-Carbidopa p.o. HGH concentration in the serum was determined at standard intervals. All subjects showed a sufficient increase of HGH. The mean value was 19.6 ng/ml. According to the maximum values of the HGH concentration the sample can be divided into two groups; the first group reached the highest values after 20–40 min, the second one after 60–90 min. On evaluation of the curve of the mean values it appears that 2 blood samples taken 40 and 90 min after the ingestion of l-Dopa and l-Carbidopa are sufficient in order to exclude HGH deficiency. The theoretical background for HGH secretion after stimulation by l-Dopa and l-Carbidopa is discussed.

    Transient hypothyroidism associated with prematurity, sepsis, and respiratory distress (1979)

    Notes: Abstract Serial TSH and T4 determinations were performed in sixty neonates admitted to our hospital for neonatal intensive care within a period of three months. Seven patients (12%) showed transient hypothyroidism on the basis of low T4 and high TSH values. Only one of these patients, who had meconium aspiration and pneumonia, did not have the respiratory distress syndrome. In addition, 4 of these patients had sepsis. All of the patients were born before 37 gestational weeks and had birth weight under 2200 g. In addition, two patients of this gestational age and birth weight group had a progressive fall of T4 to extremely hypothyroid values without simultaneous elevation of TSH. Two of the 5 patients who died had histological studies of their thyroids. These revealed colloid-depleted vesicles, desquamated epithelium, and prominent vascularisation of the thyroid. The results of this study show that early recognition and therapy of transient hypothyroidism may be live saving.

    Detection of a novel “cryptic” plasmid of about 7.8 MDal in a non-penicillinase-producing Neisseria gonorrhoeae isolate from Munich (1990)

    Notes: Abstract A novel plasmid of about 7.8 megadaltons (MDal) could be detected in a non-penicillinase-producing Neisseria gonorrhoeae strain isolated in Munich in 1987. As the strain showed no resistance against commonly used chemotherapeutic agents, at present the plasmid must be described as phenotypically “cryptic”.

    Complex differential games of pursuit-evasion type with state constraints, part 2: Numerical computation of optimal open-loop strategies (1993)

    Topics: Mathematics
    Notes: Abstract In Part 1 of this paper (Ref. 1), necessary conditions for optimal open-loop strategies in differential games of pursuit-evasion type have been developed for problems which involve state variable inequality constraints and nonsmooth data. These necessary conditions lead to multipoint boundary-value problems with jump conditions. These problems can be solved very efficiently and accurately by the well-known multiple-shooting method. By this approach, optimal open-loop strategies and their associated saddle-point trajectories can be computed for the entire capture zone of the game. This also includes the computation of optimal open-loop strategies and saddle-point trajectories on the barrier of the pursuit-evasion game. The open-loop strategies provide an open-loop representation of the optimal feedback strategies. Numerical results are obtained for a special air combat scenario between one medium-range air-to-air missile and one high-performance aircraft in a vertical plane. A dynamic pressure limit for the aircraft imposes a state variable inequality constraint of the first order. Special emphasis is laid on realistic approximations of the lift, drag, and thrust of both vehicles and the atmospheric data. In particular, saddle-point trajectories on the barrier are computed and discussed. Submanifolds of the barrier which separate the initial values of the capture zone from those of the escape zone are computed for two representative launch positions of the missible. By this way, the firing range of the pursuing missile is determined and visualized.

    Notes: Abstract Complex pursuit-evasion games with state variable inequality constraints are investigated. Necessary conditions of the first and the second order for optimal trajectories are developed, which enable the calculation of optimal open-loop strategies. The necessary conditions on singular surfaces induced by state constraints and non-smooth data are discussed in detail. These conditions lead to multi-point boundary-value problems which can be solved very efficiently and very accurately by the multiple shooting method. A realistically modelled pursuit-evasion problem for one air-to-air missile versus one high performance aircraft in a vertical plane serves as an example. For this pursuit-evasion game, the barrier surface is investigated, which determines the firing range of the missile. The numerical method for solving this problem and extensive numerical results will be presented and discussed in Part 2 of this paper; see Ref. 1.
