Nocebo: the psychologic induction of pain.

More than two-thirds of an unselected sample of 34 college students reported mild headaches when told that a (nonexistent) electric current was passing through their heads. These reports appeared independent of whether the instructions emphasized the headache-producing effect of the current or whether the emphasis was on a perceptual task, with headache as only a possible side effect. The results are consistent with a view of pain as localized stress. They provide additional grounds for the suspicion that clinical focusing on pain may itself be a cause of pain.

Serum cathepsin H as a potential prognostic marker in patients with colorectal cancer.

Cathepsin H is a lysosomal cysteine protease that may participate in tumor progression. In order to evaluate its potential as a prognostic marker, its protein levels were measured by ELISA in preoperative sera from 324 patients with colorectal cancer. The level of cathepsin H was significantly increased in patient sera, the median level was 8.4 ng/mL versus 2.1 ng/mL in 90 healthy blood donors (p < 0.0001). A weak association of cathepsin H levels was found with patient age (p = 0.02) but not with Dukes' stage, sex, or the level of carcinoembryonic antigen (CEA). In survival analysis a significant difference was found between the group of patients with low cathepsin H (first tertile) who had a poor prognosis and the remaining patients (p = 0.03). The risk of patients was further stratified when cathepsin H levels were combined with CEA. Patients with high CEA and low cathepsin H had the highest risk of death with a hazard ratio of 2.72 (95% CI 1.73-4.28), p < 0.0001. Our results show that the prognostic information of cathepsin H differs from that of the related cathepsins B and L and suggest different roles during the progression of malignant disease.
