Since clinical trials have demonstrated that breast conservation is safe and effective for treatment of invasive breast cancer, there has been considerable disagreement and controversy about what constitutes an acceptable margin in breast cancer. Dogmatic adherence to a set margin for all patients may cause a higher mastectomy rate than necessary, and thus it is important to understand how various clinical and pathologic factors affect local recurrence and outcome. This review discusses that controversy, as well as what factors should be considered when evaluating patients on an individual basis.

Summary

Background: The purpose of this study was to assess whether the addition of intravenous magnesium sulphate (Mg) at the induction of anaesthesia to a balanced anaesthetic protocol including wound infiltration, paracetamol and tramadol resulted in improved analgesic efficiency after radical prostatectomy. Methods: We conducted a randomized, double-blind, controlled study. Thirty ASA I or II males scheduled to undergo radical retropubic prostatectomy with general anaesthesia were prospectively assigned to one of the two groups (n = 15 each). The Mg group (Gr Mg) received 50 mg kg−1 of MgSO4 in 100 mL of isotonic saline over 20 min immediately after induction of anaesthesia and before skin incision. The patients in the control group (Gr C) received the same volume of saline over the same period. At the time of abdominal closure, wound infiltration with 190 mg (40 mL) of ropivacaine was performed in both groups. Pain was assessed by a 10-point visual analogue scale in the recovery room starting from the time of tracheal extubation. Standardized postoperative analgesia included paracetamol and tramadol administered via a patient-controlled analgesia device. Results: In the postoperative period, both groups experienced an identical pain course evolution. Cumulative mean tramadol dose after 24 h was 226 mg in the magnesium group and 446 mg in the control group (P < 0.001). Postoperative nausea occurred in two patients in each group. Two vs. eight patients required analgesic rescue in magnesium and control groups, respectively (P = 0.053). Conclusions: This study shows that intravenous magnesium sulphate reduces tramadol consumption when used as a postoperative analgesic protocol in radical prostatectomy.

Objective: To describe a population-based, multifaceted shared-care intervention for late-life depression in residential care as a new model of geriatric practice, to outline its development and implementation, and to describe the lessons learned during the implementation process. Setting: A large continuing-care retirement community in Sydney, Australia, providing three levels of care (independent living units, assisted-living complexes, and nursing homes). Participants:) The intervention was implemented for the entire non-nursing home population (residents in independent and assisted living: N = 1,466) of the facility and their health care providers. Of the 1,036 residents who were eligible and agreed to be interviewed, 281 (27.1%) were classified as depressed according to the Geriatric Depression Scale. Intervention Description: The intervention included: (a) multidisciplinary collaboration between primary care physicians, facility health care providers, and the local psychogeriatric service; (b) trainning for primary care physicians and other facility health care providers about detecting and managing depression; and (c) depression-related health education/promotion programs for residents. Conclusions: The intervention was widely accepted by residents and their health care providers, and was sustained and enhanced by the facility after the completion of the study. It is possible to implement and sustain a multifaceted shared-care intervention for late-life depression in a residential care facility where local psychogeriatric services are scarce, staff-to-resident ratios are low, and the needs of depressed to residents are substantial.

Forty-two patients were treated for sarcoma of the nasal cavity and paranasal sinuses at the Institut Gustave Roussy, Paris, between 1960 and 1993. Twelve patients had chondrosarcoma (CS), 14 had osteosarcoma (OS) and 16 had fibrosarcoma (FS). Ten patients had grade I, six grade II and 26 grade HI tumours.

All but 10 patients had surgery for the primary tumour. A significantly increased risk of local failure was associated with the male sex (p <0.01), grade III tumours (p <0.02) and patients excluded from surgery (p <0.04). The overall incidence of local and distant failure was 76 and 12 per cent respectively. Overall survival was 28 per cent at three years and 23 per cent at five years. Eight patients (20 per cent) were alive more than 10 years later. The factors significantly influencing survival were sex (p <0.01), grade (p <0.05) and local failure (p<0.01).

The results of single modality treatment using surgery or radiotherapy alone in advanced head and neck cancers are known to be unsatisfactory. The present study analyses 252 cases with stage III and IV resectable cancers of the head and neck region selected to be treated by a combined regime of pre- or post-operative radiation and radical surgery. Only 193 patients completed the treatment protocol. There were 58 cases (33.5 per cent) who failed either at primary or regional sites or both. Nine cases (five per cent) developed distant metastasis. Absolute and determinate four year disease-free survival was 55 per cent and 61 per cent respectively. Early lesions (stage I and II) have been excluded from the study. The study indicates that a reduction in primary and regional failures correlates well with a combined therapy, though prolonged treatment may affect patients' compliance to some extent.
