ABSTRACT
BACKGROUND: We have previously shown that hypnotherapy alters rectal sensitivity in some patients with irritable bowel syndrome. However, this previous study used incremental volume distension of a latex balloon, which might be susceptible to subject response bias and might compromise the assessment of compliance. In addition, the study group was symptomatically rather than physiologically defined. AIM: To assess the effect of hypnotherapy on rectal sensitivity in hypersensitive, hyposensitive and normally sensitive irritable bowel syndrome patients using a distension technique (barostat) that addresses these technical issues. METHODS: Twenty-three irritable bowel syndrome (Rome I) patients (aged 24-72 years) were assessed before and after 12 weeks of hypnotherapy in terms of rectal sensitivity, symptomatology, anxiety and depression. Normal values for sensitivity were established in 17 healthy volunteers (aged 20-55 years). RESULTS: Compared with controls, 10 patients were hypersensitive, seven hyposensitive and six normally sensitive before treatment. Following hypnotherapy, the mean pain sensory threshold increased in the hypersensitive group (P = 0.04) and decreased in the hyposensitive group, although the latter failed to reach statistical significance (P = 0.19). Normal sensory perception was unchanged. Sensory improvement in the hypersensitive patients tended to correlate with a reduction in abdominal pain (r = 0.714, P = 0.07). CONCLUSION: Hypnotherapy improves abnormal sensory perception in irritable bowel syndrome, leaving normal sensation unchanged.

BACKGROUND: The goal was to examine tattooing in suicides, as tattoos have been associated with several risk factors for suicide. METHOD: A chart review of a three-year sample of 134 consecutive suicides in Mobile County, Alabama, was conducted. The prevalence of tattoos was compared between young (<30) white suicides and accidental deaths matched for age, gender and race, in a case-control study. RESULTS: Tattoos were found in 21% of suicides. Fifty-seven percent of young white suicides were tattooed compared to 29% of matched accidental deaths. LIMITATIONS: Findings are preliminary due to the small sample size. The study methodology precluded obtaining information of psychiatric diagnoses prior to death. CONCLUSIONS: Tattoos may be possible markers for lethality from both suicide and accidental death in young people, presumably because of shared risk factors such as substance abuse and personality disorder. Affective disorders should receive further, more specific studies. The clinical value of inquiring about tattoos in young people at risk of suicide needs further study.

Male CD1 mice were exposed in utero to a 50 Hz sinusoidal magnetic field at 5 mT (rms) for the period of gestation and were raised subsequently without applied fields. At 82-84 days of age, they began a radial-arm-maze experiment that was designed to test for deficits in spatial learning and memory. Mice exposed in utero and sham-exposed mice exhibited no statistically significant differences in performances.
