RESUMO
The incidence of breast carcinoma increases with advancing age. In view of the progressive aging of the population, this problem will tend to become more and more frequent. At present, patients of advanced age are often "undertreated" owing to the mistaken prejudice that older patients are unable to withstand standard multimodal therapy for this disease. In fact, there is no scientific evidence to that effect. Treatment choices should therefore be largely comparable to those adopted in younger patients. Even chemotherapy, which encounters the strongest resistance, by patients but also by doctors, should be administered when indicated. A number of studies have demonstrated that the toxic and side effects observed in elderly patients are comparable to those observed in younger age groups. In practice, particular attention needs to be paid when administering cytostatic treatment to patients over 80 years of age. Very conservative treatment (tamoxifen plus radiotherapy) may be reserved only to particularly frail elderly patients. In conclusion, the therapeutic choice should depend more on assessment of the biological age, life expectancy and patient's expectations than on the anagraphic age.

We present a case of death caused by voluntary ingestion of non-organic foreign bodies observed at the Institute of Legal Medicine of the University of Trieste. The victim was a young schizophrenic patient whose death, at first giving rise to suspicions of murder by another psychiatric patient, was found to be caused by an uncommon chronic permanence of foreign bodies at different locations of the digestive tract which suddenly evolved into a series of simultaneous lethal complications as yet never described. The case also raised the issue of possible responsibilities of the subject's healthcare providers.

PURPOSE: The aim of this study was to demonstrate the feasibility, effectiveness, and reliability of a new technique for treating overt rectal mucosal prolapse using a stapler device. METHODS: Eighteen consecutive patients with overt rectal mucosal prolapse were selected for the study. Preoperative anal manometry and cinedefecography demonstrated no anal incontinence and the absence of full-thickness rectal prolapse. One or two purse strings were prepared 3 to 4 cm distally to the dentate line and tied on a 33 mm circular stapler introduced through the anus and then fired. RESULTS: The operation lasted an average of 15 minutes, and no local complications were recorded. Supplementary hemostatic sutures (2 to 6 stitches) were sometimes necessary. Seven patients did not require postoperative analgesia, whereas eight patients received one or two administrations of analgesics. Longer-lasting analgesic treatment (4 days) was necessary in only three patients. Sixteen patients were discharged after 48 hours, and only 1 after four days because of pulmonary infection. Patients resumed normal activities after a median period of three days. Median follow-up was 20 months. The prolapse was eliminated in all cases. No stricture was found at anal exploration, and no episodes of anal incontinence or bleeding were recorded. Postoperative manometry did not show significant changes compared with preoperative findings. CONCLUSIONS: This new surgical technique is safe, effective, and rapid, causing minimum or no postoperative pain and could be proposed to replace traditional surgery for this common condition.

The measurement of estrogen as well as progesterone receptors has been applied clinically to predict the effectiveness of endocrine therapy in patients with breast or endometrial carcinoma. The presence of cytosolic estrogen receptors in human colorectal carcinomas has been reported by several different groups during the past 10 yr. The aim of our current study was to evaluate the estrogen binding activity in the nuclear and cytosolic fractions of these carcinomas, as well as in surrounding noncancerous colonic tissue. Twenty-six patients, operated on for colorectal carcinoma, were studied: 16 were men and 10 were postmenopausal women, mean age 61 yr (range 43-78 yr). In neoplastic tissue, cytosolic estradiol receptors were detected in 42.3% of the patients (women 40%, men 43.7%). The values for cytosolic estrogen receptor ranged from 118 to 1214 fmol/g wet colon. Nuclear estrogen receptors were detectable in 46.1% of the patients (women 40%, men 50%) and their values displayed a range from 3.4 to 2554 fmol/g wet colon. In 30.7% of the patients, both nuclear and cytosolic receptors were demonstrated. In 38.4% of the patients, receptors were found in neither cytosol nor nuclei. Receptor positivity in men was most frequently associated with tumors removed from the rectum, and those with Dukes' classification of C1. In the surrounding noncancerous tissue cytosolic estrogen receptors were also detected (range 133-1105 fmol/g wet colon) and were present in 34.6% of the patients (women 30%, men 37.5%). Nuclear estrogen receptors (range 225-1105 fmol/g wet colon) were detected in 57.6% of the patients (women 40%, men 68.7%). In 23% of the patients, both nuclear and cytosolic receptors were demonstrated. In 30.7% of the patients, no receptors were found in either cytosol or nucleus. Therefore, the presence of cytosolic or nuclear estrogen receptors, or both, in 61.6% of human colorectal cancer specimens emphasizes the need to evaluate both forms of these receptors for studies of potential hormone dependence in these tumors.

Effects of amethopterin (MTX) on lymphoid tissue of rabbit appendix have been evaluated. The drug caused an evident depletion of lymphoid cells. This finding suggested the relevance of cytotoxicity in the mechanism of immune suppression. Discontinuation of drug treatment demonstrated a tendency toward the reorganization of the lymphoid tissue.
