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.
