    Description / Table of Contents: Summary Neuroborreliosis is a very frequent subtype of infection with Borrelia burgdorferi. Because of the widely spread inapparent infections finding of diagnosis by analysis of serum antibodies is very difficult. In the years 1990–1994 the serum of 6.775 patients of the Department of Neurology in Homburg, Germany was analysed with regard to Borrelia burgdorferi specific IgG antibodies. 24% showed a positive serum titer and 20% a borderline result. 73 patients showed a specific intrathecal IgG antibody synthesis. In contrast to patients with antibodies in serum these patients showed a significant cumulation during summer. The high percentage of positive serum titers and the season independence support the assumption of widely spread inapparent infections. If a patient shows neurological symptoms the finding of serum antibodies against Borrelia burgdorferi is not sufficient for the diagnosis of Neuroborreliosis. A specific intrathecal synthesis of antibodies, is the most reliable serological indicator for Neuroborreliosis. Intrathecal synthesis usually starts three to four weeks after the first clinical symptoms.
    Notes: Zusammenfassung Die Neuroborreliose ist die zweithäufigste Manifestationsform einer Infektion mit Borrelia burgdorferi. Die serologische Diagnostik durch Bestimmung von IgG-Antikörpern wird durch einen hohen Prozentsatz an stummer Durchseuchung in der Bevölkerung erschwert. Von 1990 bis 1994 wurden in der Neurologischen Universitätsklinik Homburg 6775 Patienten serologisch auf Borrelia-burgdorferi-spezifische IgG-Antikörper untersucht. In 24% der Fälle wurde ein positiver Serumtiter und in 20% ein grenzwertiger Titer festgestellt. Der Nachweis einer spezifischen intrathekalen IgG-Antikörperproduktion konnte bei 73 Patienten geführt werden. Während bei der Aufschlüsselung der Daten aus den Serum-IgG-Untersuchungen auf die einzelnen Monate keine relevanten jahreszeitlichen Schwankungen sichtbar waren, zeigte sich bei dem Anteil der IAI-positiven Fälle eine signifikante Häufung in den Sommermonaten. Der hohe Prozentsatz von Patienten mit positiven Serumtitern gegen Borrelia burgdorferi sowie die fehlende jahreszeitliche Schwankung deuten auf eine stumme Duchseuchung hin. Eine Seropositivität genügt beim Vorliegen einer neurologischen Symptomatik nicht zum Nachweis einer Neuroborreliose. Vielmehr ist der Nachweis einer spezifischen intrathekalen Antikörpersynthese der zuverlässigste serologische Hinweis auf eine Neuroborreliose. Das Einsetzen dieser intrathekalen Synthese erfolgt in der Regel jedoch erst in der 3.–4. Woche nach Beginn der Symptomatik.

    Notes: Summary Intravenous administration of amantadine has been shown to be a quick-acting and highly effective method of treating patients with Parkinson's disease. The duration of this therapeutic effect during long-term oral treatment has, however, remained controversial. Therefore, the effect of intravenous treatment was compared with long-term oral treatment over a period of 6 months. Clinical scores and psychometrically determined dexterity improved significantly during 10-day infusion therapy (200 mg amantadine sulphate/day). This improvement was successfully maintained by oral treatment (600 mg/day). A decrease in effectiveness was not observed. Reaction times were within the normal range for the age group involved and did not change significantly during the course of the study. Amantadine serum concentration during the infusion period ranged between 500 and 1000 μg/l and produced values nearly half as high as those obtained during oral treatment (600 mg/day). There was a constant relationship (quotient: 1.3) between serum and cerebrospinal fluid concentration. Considerable inter-individual variations were noted. A significant inter-individual correlation between serum concentration and clinical and psychological improvement was not discernible.

    Notes: Abstract It is well known that blood pressure is elevated during acute stroke. Despite its importance for cerebral haemodynamics, cardiac output (CO) has been determined only in individual cases during acute stroke. We measured CO and blood pressure in patients with no history of heart disease who suffered from acute stroke (n = 30) and in a control group comparable with regard to age, gender and cardiac health (n = 30). CO, blood pressure and heart rate were significantly (P 〈 0.01) higher in the group of stroke patients than in the control group. There was a tendency for more time to have elapsed between the onset of symptoms and measurements, the higher the CO [b = 0.08 l/min per hour (−0.01; 0.17)]. Adjusted for age in a multiple regression model, the regression coefficient was significant (CO = 10.35 + 0.094 × time − 0.077 × age). The present study shows for the first time that patients with a healthy cardiovascular system who suffer from acute stroke have a higher CO than a group of comparable controls.
