    Trace gas exchange at the air/water interface: Measurements of mass accommodation coefficients (1990)
    Springer
    Journal of atmospheric chemistry 10 (1990), S. 427-449

    ISSN: 1573-0662
    Keywords: Mass accommodation coefficient ; liquid jet ; interface ; HCl ; HNO3 ; N2O5 ; peroxyacetyl nitrate (PAN) ; HONO

    Notes: Abstract A liquid jet of 90 μm diameter and variable length has been utilized to determine absorption rates and, hence, mass accommodation coefficients γ, of atmospheric trace gases. The compounds investigated are HCl (γ≥0.01), HNO3 (γ≥0.01), N2O5 (γ≥0.005), peroxyacetyl nitrate (γ〉0.001), and HONO (γ≥0.005). It is concluded that the absorption of these trace gases by liquid atmospheric water is not significantly retarded by interfacial mass transport. The strengths and limitations of the liquid jet technique for measuring mass accommodation coefficients are explored.

    Notes: Summary. Glutathione S-transferases (GSTs) are involved in the detoxification of endogenous or exogenous toxins, which may play a role in the pathogenesis of Parkinson's disease. We genotyped the Glutathione-S-Transferase isoenzymes GSTM1 and GSTT1 by polymerase chain reaction in order to evaluate different gene polymorphisms of these isoenzymes in 149 parkinsonian and 99 control subjects. No differences appeared between both groups regarding the frequencies of the homozygous deletion of GSTM1 (odds ratio 1.021; 95% Cl [0.613; 1.699], p 〈 0.521 Fisher's exact test) and GSTT1 (odds ratio 1.514; 95% Cl [0.811; 2.824], p 〈 0.127). Age of onset of PD did notcorrelate to GSTM1 and GSTT1 polymorphisms. These results do not support the hypothesis of a possible impact of GSTM1 and GSTT1 detoxification activities in the pathogenesis of Parkinson's disease.

    Description / Table of Contents: Zusammenfassung Die Halswirbelsäule (HWS) als äußerst komplexe Funktionseinheit war schon immer Gegenstand heftiger Diskussionen zwischen Chirurgen, Orthopäden und Neurologen. Bei entsprechenden Verletzungen, die teilweise gravierende Konsequenzen – auch versicherungsrechtlicher Natur – nach sich ziehen, befinden sich die Neurologen meist am Ende der diagnostischen und therapeutischen „Kette“. Zu wünschen wäre eine möglichst frühzeitige Einschaltung des Neurologen mit seinen klinischen und apparativ-neurophysiologischen Möglichkeiten. In dem nachfolgenden Beitrag soll der Stellenwert der Neurologie in der Diagnostik und Therapie von Beschleunigungsverletzungen der HWS diskutiert werden. Die neueren Möglichkeiten – insbesondere in der Neurophysiologie – werden ebenso aufgezeigt wie differentialdiagnostische Überlegungen und gutachterliche Probleme, die wiederum andere Fachgebiete tangieren.
    Notes: Summary The cervical spine is an extremely complex functional unit and has always been the subject of impassioned discussions among surgeons, orthopedic specialists and neurologists. In the presence of injuries affecting this section of the spine, which sometimes have grave consequences – including implications for legal insurance aspects, neurologists are usually at the end of the line when it comes to diagnosis and treatment. In fact, in view of the clinical and technical neurophysiological options available to neurologists, it would be desirable for them to be involved as early as possible. In this paper the relative value of neurology, compared with orthopedics and surgery, in the diagnosis and treatment of whiplash injury to the cervical spine is discussed. The newer options available – particularly in neurophysiology – are highlighted, as are the differential diagnosis and problems concerned with official expert assessments, which also involve other specialties.

    Description / Table of Contents: Summary The long-standing consultant service for neurological patients in a general hospital requires questions to about the dimensions and efficiency of being answered cooperation between a general hospital and a neighbouring neurological clinic with a casualty ward and neuroradiology. From 1987 to 1995, 1471 patients with neurological diagnoses were observed retrospectively. The small number of requested consultancies (4–5%) was conspicious related to the total member of patients treated in the general hospital. About 25% of the recommendations of the consultants were realized. The percentage of pensioners and housewives was distinctly higher (45%). With the help of the diagnosis ”concussion of the brain” good cooperation was observed between the general physicians to whom the consultant’s recommendations had been passed on and the neurological casualty ward. The results, tendencies and possibilities for improvement of interdisciplinary cooperation are discussed.
    Notes: Zusammenfassung Die jahrelange konsiliarische Betreuung von neurologischen Patienten eines Krankenhauses der Grund- und Regelversorgung wirft Fragen nach Umfang und Effizienz dieser Zusammenarbeit zwischen einem Allgemeinkrankenhaus und einer benachbarten neurologischen Klinik mit Ambulanz und Neuroradiologie auf. 1471 Patienten mit neurologischen Diagnosen wurden im Zeitraum von 1987–1995 retrospektiv erfaßt. Dabei fiel zunächst die geringe Zahl der angeforderten Konsile auf, bezogen auf die Gesamtzahl der im Allgemeinkrankenhaus behandelten Patienten (4,5–5%). Die Empfehlungen der Konsiliarärzte wurden durchschnittlich in 25% realisiert, bei Rentnern und Hausfrauen lag der Prozentsatz deutlich höher (45%). Am Beispiel der Diagnose „Commotio cerebri” konnte eine gute Zusammenarbeit zwischen Hausärzten, an die die Empfehlungen des Konsiliarius weitergegeben wurden, und neurologischer Ambulanz beobachtet werden. Ergebnisse, Tendenzen und Verbesserungsmöglichkeiten der interdisziplinären Zusammenarbeit werden kritisch diskutiert.

    Visual hallucinosis: The major clinical determinant of distorted chromatic contour perception in Parkinson's disease (1996)

    Notes: Summary Recently distorted chromatic contour perception has been demonstrated in Parkinson's disease (PD). The aim of our study is to determine the clinical factors which influence chromatic contour perception in PD. Chromatic and achromatic contour perception, colour discrimination and clinical data were evaluated in 73 patients with PD. We used a computer-aided method to determine the chromatic fusion time (CFT) which indicates the acuity of monochromatic contour perception. Chromatic CFT was generally shortened in patients as compared to controls (p 〈 0.01), whereas achromatic CFT was not significantly different. Variance analysis revealed the ability of colour discrimination and the risk of visual hallucinations as statistically significant (p 〈 0.05) variables influencing contour perception of certain stimuli. In contrast, disease stage, disease duration and disease severity have no relevant effect on chromatic contour perception in Parkinson's disease. On the basis of those properties one may suggest that distorted chromatic contour perception is due to an impairment at a central stage of visual processing in PD and an imbalance of the serotonergic system. Whether CFT is a reliable method to predict the individual risk of hallucinosis in PD has to be evaluated.

    The motor performance test series in Parkinson's disease is influenced by depression (1996)

    Notes: Summary The Motor Performance Test Series (MPTS) is widely used for treatment control in Parkinson's disease (PD). To elucidate the possible influence of depression on the fine motor skills in PD, 54 patients with idiopathic PD were investigated with the MPTS. 27 patients with major intensity of depression were compared to 27 age and motor disability matched patients with minor symptoms of depression, evaluated by the Zung depression scale. As determined by the subtest aiming, a significant lower ability for precise, quick complex arm-hand movements in depressed Parkinsonian patients was found. This result may be explained partly by motivation deficits in depressed patients with PD. On the other hand impairment of special motor loops including frontal lobe projections to specific thalamic subnuclei or to the caudate nucleus may cause disturbances of the subtest aiming in depressed Parkinsonian patients. On the basis of these findings impaired aiming may be explained by diminished ability for complex, semivoluntary movements in depressive Parkinsonian patients. The influence of psychiatric comorbidity on MPTS subtest aiming has to be considered in further therapy studies using evaluation of motor deficits by MPTS.
