    Notizen: Abstract Eight healthy subjects were exposed to three 1/3 octave-band vibrations (63, 200, and 500 Hz) by hand clasping a vibrated handle in a soundproof and thermoregulated room. The vibratory sensation threshold at 125 Hz was measured before and after the vibration exposure at an exposed fingertip. According to a preceding study, we first determined the relationship between the acceleration of the vibration and the temporary threshold shift of vibratory sensation immediately after the vibratory exposure (TTSv,0) induced by 1/3 octave-band vibration. We then measured TTSv after the exposure to a composite vibration composed of two 1/3 octave-band vibrations that might induce an equal magnitude of TTSv,0 on the basis of the above relationship. The TTSv,0 induced by the composite vibration was not larger than the TTSv,0 induced by the component vibrations. This result suggests that the component of the vibration inducing the largest TTSv,0 determines the TTSv,0 by broad-band random vibration.

    Notizen: Abstract ⋅Objective This study examines the effect of the force with which a vibrating handle is gripped on the temporary threshold shift of vibratory sensation (TTSv) induced by hand-arm vibration. ⋅  Methods Six healthy subjects gripped a handle vibrating with a 1/3 octave-band vibration, with a central frequency of 200 Hz and an intensity of 39.2 m/s2. Exposure was for 1 min and 10 min, respectively. Gripping forces for the 1-min exposure were 5 N, 10 N, 40 N and 80 N, respectively, with 0 N push-pull force. Gripping forces for the 10-min exposure were the same as for the 1-min exposure, but omitting 80 N. The vibratory sensation threshold at 125 Hz was measured before and after exposure of an exposed fingertip to vibration. The differences measured determine TTS v,t at time t. TTS v,t determines TTSv,0, that is, the temporary threshold shift of vibratory sensation immediately after exposure to vibration according to the estimate made on the basis of the preceding study. The same experimental conditions were repeated 3 times on different days in a soundproof and thermoregulated room. ⋅  Results Our findings show that TTSv increases significantly with increasing gripping force. We also determined the quantitative relationships between TTSv,0 and gripping force as described by the equation where k f and c f are constants and F is gripping force. ⋅  Conclusion This study revealed the importance of ergonomic design in reducing the force with which a vibrating handle is gripped to prevent an adverse effect of local vibration. The equation devised may help in the quantitative assessment of the effect of reduced gripping force.

    Notizen: Abstract PURPOSE: We categorized the various types of postobstetric injuries of the anorectum and vagina encountered in a five-year period. The operative procedures used to repair these injuries and the functional outcome after surgery were assessed. METHODS: Between 1986 and 1991, 52 patients were surgically treated for obstetric injuries of the anorectum and vagina; 48 patients were available for follow-up study. Four clinical injury types were identified: Type I, incontinent anal sphincter (11 patients); Type II, rectovaginal fistula (16 patients); Type III, rectovaginal fistula and incontinent anal sphincter (11 patients); and Type IV, cloaca-like defect (10 patients). The mean age of the patients was 30 years, the mean duration of symptoms before surgery was 13 months, and the mean follow-up period was 16 months. The major component of surgical repair for each injury type was: Type I, overlap repair of external anal sphincter; Type II, rectal mucosal advancement flap; Type III, overlap repair of external anal sphincter and rectal mucosal advancement flap; and Type IV, overlap repair of external anal sphincter, anterior levatorplasty, and anal and vaginal mucosal reconstruction. Fecal diversion was not performed in any patient. Specific questions were asked at the most recent follow-up assessment to determine results. RESULTS: Continence status postoperatively was classified as perfect, impaired, or poor; poor was defined as no improvement or worse. Postoperative continence (perfect, impaired, or poor) was, respectively: Type I (11 patients), 64 percent, 36 percent, and 0 percent; Type II (16 patients), 56 percent, 0 percent, and 44 percent; Type III (11 patients), 64 percent, 36 percent, and 0 percent; and Type IV (10 patients), 90 percent, 10 percent, and 0 percent. Vaginal discharge of stool was eliminated in all patients with a rectovaginal fistula. Subjectively, 92 percent of the patients had excellent or good results. Complications included wound hematoma (n=2), fecal impaction (n=2), urinary retention (n=1), and urinary tract infection (n=1). CONCLUSION: Patients with Type II injuries had the worst results (P 〈 0.001). These patients should be evaluated for anal incontinence before surgery to assess the need for a concomitant sphincteroplasty.
