    Notizen: [Auszug] Allcock and I have reported that the simultaneous observation of whistlers at conjugate points in the northern and southern hemispheres bears out the essential details of Storey?s hypothesis, and Helliwell and Gehrels have found that very low-frequency broadcast signals can be received in the ...

    Notizen: [Auszug] WE have observed whistlers, most recently described comprehensively by L. R. O. Storey1, to occur simultaneously at 55*1 and 50 '2 N. geomagnetic latitude on the east coast of North America, and have found the individual whistlers to have essentially identical characteristics at the two ...

    Notizen: [Auszug] OBSERVATIONS which we have conducted near geomagnetically conjugate points at about 50 geomagnetic latitude in the Aleutian Islands and in New Zealand appear to confirm L. R. O. Storey's remarkable theory that the long, dispersive paths needed by T. L. Eckersley to explain the generation of ...

    Treatment of urinary infection in the elderly (1990)
    Springer
    Infection 18 (1990), S. 326-331 
    Details
    ISSN: 1439-0973
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Conclusion Effective drugs are available for the short-term treatment and long-term prophylaxis of UTI in the elderly population in the absence of obstructive uropathy, just as in younger patient groups. The frequency of treatment failures and adverse reactions varies with the type and dosage of the drug in use as well as the subpopulation of elderly patients being treated. Controlled studies with an adequate number of subjects are needed to determine the effect of short-term treatment on a “pro-re-nata basis”, and long-term chemoprophylaxis on the quality of life and longevity in elderly patients. The treatment and control groups should provide valuable epidemiological data on the natural history of ABU, its effect on renal function and longevity as well as such factors as mental status, incontinence and mobility. These parameters collectively determine the quality of life of our increasing numbers of senior citizens and to some extent, also those who care for them. Any simple and inexpensive step that can be taken to improve quality of life is justified and must be explored with vigour.

    Controversies in the laboratory diagnosis of community-acquired urinary tract infection (1993)
    Springer
    European journal of clinical microbiology & infectious diseases 12 (1993), S. 491-504 
    Details
    ISSN: 1435-4373

    Thema: Medizin
    Notizen: Abstract Urine samples constitute the largest single category of specimens examined in most medical microbiology laboratories. The everyday nature and apparent simplicity of urinary tract infection belies the intense debate and controversy regarding the optimal methods of collection, transport and processing of urine specimens and reporting of results. There is considerable variation in the interpretation of quantitative culture results between laboratories and the etiology of abacterial cystitis remains unclear. Microscopy to detect pyuria provides information on an important indicator of inflammation and it has been proposed that detection of urinary antibody may provide similar information. Neither of these indices of host response is suitable for use in a screening test for urinary infection however, although they may usefully contribute to the interpretation of significance of culture results. The development of screening tests and automated systems continues, but at present microscopy and culture remain the most important techniques for laboratory diagnosis. However, these techniques have so far failed to provide an etiological diagnosis for abacterial cystitis and this remains a major area for research.

    Use of molecular methods to characterizeMoraxella catarrhalis strains in a suspected outbreak of nosocomial infection (1992)
    Springer
    European journal of clinical microbiology & infectious diseases 11 (1992), S. 305-312 
    Details

    Thema: Medizin
    Notizen: Abstract Sodium dodecyl sulphate-polyacrylamide gel electrophoresis of whole cell protein, immunoblotting with normal human serum and restriction endonuclease analysis usingTaq I enzyme were applied to 38 clinically significant isolates ofMoraxella (Branhamella) catarrhalis obtained during a suspected outbreak of nosocomial infection. Each of 18 strains had individual profiles by at least two of the three methods (unique strains). The remaining 20 strains were assigned to five groups (A-E) on the basis of similarity by at least two of the three methods. Isolates within groups A, D and E were homologous by all three methods. Immunoblot groups B and C had two distinct whole cell protein profiles (B1 and B2) but indistinguishable restriction endonuclease profiles (group B/C). This emphasizes the need to use more than one technique in characterizing strains from suspected outbreaks of nosocomial infection. Grouped strains were more likely to originate from the same hospital ward than unique strains and were associated with a significantly longer median time from patient admission to strain isolation (14 versus 3.5 days, p〈0.005). Furthermore, the β-lactamase activity was homologous within the groups. The results suggest that nosocomial infection involving several distinctMoraxella catarrhalis strains persisted over a period of months, involving at least 20 patients on three different wards. Such infection is probably common in wards harbouring suitably predisposed patients. The mode of transmission remains to be elucidated, but the above three techniques possess sufficient reproducibility and discriminatory ability to constitute suitable investigative tools.
