    Notes: Abstract PURPOSE: Biofeedback therapy in fecal incontinence has been reported to improve continence in more than 70 percent of patients, but most studies have followed patients for less than two years. METHODS: Patients treated by biofeedback training between 1985 and 1986 were given a questionnaire in 1991, as were incontinent patients who had not entered this treatment program. All were asked for the occurrence, frequency, and severity of incontinence events in the past two weeks. Anamnestic and anorectal manometry data from the initial visit were also compared. RESULTS: Eighteen of 24 treated patients and 40 of 71 untreated patients responded. Of those treated by biofeed-back, 78 percent reported episodes of fecal incontinence as compared with 77.5 percent of those not treated by biofeedback. Severity of incontinence, however, was significantly less (P 〈0.02) in the treatment group (mean number of events, 0.2/day) than in those without treatment (1/day). In biofeedback-treated patients, it was identical with the frequency and severity reported immediately after therapy. No differences were found with respect to initial clinical data and anorectal manometry between both groups. CONCLUSION: Biofeedback training improves continence in patients not only during treatment and within the first two years but also for several years after therapy.

    Notes: A conventional fast-atom bombardment (FAB) ion source was used to achieve matrix-assisted laser desorption (MALD) in a high-mass, double-focusing, magnetic mass spectrometer. The pulsed ion signals generated by irradiation of a mixture of sample and matrix (2,5-dihydroxybenzoic acid) with either a XeF excimer Laser (353 nm) or a nitrogen laser (337 nm) were recorded with a focal-plane detector. A resolution (full-width at half maximum) of 4500 was achieved at m/z 1347.7 (the peptide substance P), 2500 for CsI cluster ions at m/z 10005.7, and 1250 for the isotope cluster of the small protein cytochrome c (horse) [M+H]+=m/z 12360 (average). Sensitivity is demonstrated with 11 fmol of substance P. A survey scan is taken to prodluce a better signal-to-noise ratio. In addition to higher sensitivity and lower matrix interference, lthe advantage of MALD over FAB is the former's lower susceptibility to the presence of salts, and competition between hydrophobic and bydrophilic components of a mixture. This feature is demonstrated by the complete MALD spectrum of a crude partial tryptic digest of spedrm-whale apomyoglobin, containing 24 peptides, representing the entire sequence of this protein.

    Notes: We examine a method to impose boundary conditions on arbitrary boundaries, introduced to make domains of infinite extent finite for the purpose of numerical calculations, when a finite element discretization based on linear, bilinear or trilinear elements is used, in one, two or three dimensions, respectively. In particular, we look at the so-called ‘free’ boundary condition, which consists in retaining the boundary integrals generated by the weighted-residuals formulation along the open boundaries and adding them to the stiffness matrix. We show that this procedure is exactly equivalent to imposing on the boundary nodes a Sommerfeld radiation condition in one dimension, and a slightly modified form of the Sommerfeld boundary condition in two and three dimensions. We also show that the procedure is not applicable to the purely elliptic case.

    Description / Table of Contents: Summary In Germany inpatient psychotherapy generally takes place in special psychosomatic hospitals. Their aims are often not clear, just as their place in the whole system of medical care. Although most of them are rehabilitation hospitals from a juridical point of view, they are many times defined as specialised hospitals which do not differentiate between treatment and rehabilitation. This lack of clear definition leads to a number of structural conflicts which largely influence the staff’s scope of action and the therapeutic work. In psychosomatic rehabilitation the doctor is taking over three social roles: the role of physician, the role of psychotherapist and the role of the expert in social medicine towards the social security institution. These social roles can be understood as a complex of behavioral expectations arising from different reference systems (social security-, hospital-, treatment-, patient-system) directed towards the social position of the doctor. Within his social position the doctor is thereby involved into certain conflicts. This article will analyze the described structural problems and try to contribute to further development of the concepts in psychosomatic rehabilitation.
    Notes: Zusammenfassung Die Versorgung der Bevölkerung mit stationärer Psychotherapie erfolgt in Deutschland überwiegend in „Psychosomatischen Fachkliniken”. Deren Zielbestimmung ist oft unklar, wie überhaupt ihre Stellung im Gesamtsystem der gesundheitlichen Versorgung. Obwohl sie von ihrem (juristischen) Status her in der Regel Rehabilitationskliniken sind, verstehen sie sich vielfach als Fachkliniken, in denen zwischen Behandlung und Rehabilitation nicht unterschieden wird. Diese Unklarheiten führen zu mannigfaltigen strukturellen Konflikten, die den Handlungsspielraum der in ihnen Tätigen wesentlich mitbestimmen und die therapeutische Arbeit beeinflussen. Das gilt insbesondere für den Arzt, der in der psychosomatischen Rehabilitation drei soziale Rollen übernimmt: die des Körperarztes, die des Psychotherapeuten und die des sozialmedizinischen Sachverständigen gegenüber der Rentenversicherung. Zwischen diesen sozialen Rollen als einem Komplex von Verhaltenserwartungen aus unterschiedlichen Bezugssystemen (Sozialversicherungs-, Kliniks, Behandlungs-, Patientensystem) an die soziale Position des Arztes kommt es zu bestimmten Konflikten. Dies wird als Beitrag zur konzeptuellen Weiterentwicklung der psychosomatischen Rehabilitation näher analysiert.

    Notes: The calculation of pressures when the penalty function approximation is used in finite element solutions of laminar incompressible flows is addressed. A Poisson equation for the pressure is formulated that involves third derivatives of the velocity field. The second derivatives appearing in the weak formulation of the Poisson equation are calculated from the C0 velocity approximation using a least squares method. The present scheme is shown to be efficient, free of spurious oscillations, and accurate. Examples of applications are given and compared with results obtained using mixed formulations.

    Notes: In one dimension, Petrov - Galerkin nonsymmetric weighting for the convective diffusion equation can be interpreted as an added dissipation. The addition of an appropriate amount of dissipation can therefore give the same oscillation-free solutions as the ‘unwinding’, Petrov - Galerkin, finite element methods. The ‘balancing dissipation’ is optimally chosen so that excessive dissipation does not occur. A scheme is presented for extending this approach to two-dimensional problems, and numerical examples show that the new method can be used with improved computational efficiency.
