RESUMO
Locally recurrent rectal cancer (LRRC) is a complex disease with far-reaching implications for the patient. Until recently, research was limited regarding surgical techniques that can increase the ability to perform an en bloc resection with negative margins. This has changed in recent years and therefore outcomes for these patients have improved. Novel radical techniques and adjuncts allow for more radical resections thereby improving the chance of negative resection margins and outcomes. In the past contraindications to surgery included anterior involvement of the pubic bone, sacral invasions above the level of S2/S3 and lateral pelvic wall involvement. However, current data suggests that previously unresectable cases may now be feasible with novel techniques, surgical approaches and reconstructive surgery. The publications to date have only reported small patient pools with the research conducted by highly specialised units. Moreover, the short and long-term oncological outcomes are currently under review. Therefore although surgical options for LRRC have expanded significantly, one should balance the treatment choices available against the morbidity associated with the procedure and select the right patient for it.

Background. Although postoperative complications are common after lymph node dissection, its association with disease recurrence has not yet been fully investigated. Methods. A retrospective review of a prospectively maintained database was conducted, looking at all malignant melanoma patients with sentinel nodes positive disease requiring axillary or inguinal dissection between 2002 and 2011. Results. A total of 124 patients required nodal clearance from 317 patients with stage I/II malignant melanoma who had undergone sentinel lymph node biopsy. Of these, 104 patients met the inclusion criteria and were divided into inguinal lymph node dissections (ILND; n = 63) or axillary lymph node dissections (ALND; n = 41). Immunohistochemical deposits had higher detection rate in ALND (P = 0.01). The ILND patients had a higher recurrence rate (84.1% versus 63.4%; P = 0.02) and mortality (68.3% versus 48.8%; P = 0.05) without a significant difference in complications. In patients whom complications developed, 75% of the ILND group and 71.4% of the ALND group had disease recurrence, but without reaching a statistical value as an independent predictor of melanoma recurrence. Conclusion. Complications are common following ILND and ALND; however there is no significant difference in complications rates between the groups with some associations with recurrence without reaching a significant difference.
RESUMO
INTRODUCTION: Changes in medical practice have promoted a culture of standardized care. Care pathways have been proven to raise the quality of clinical care. Their effect as an educational tool has not been evaluated to date. AIMS: To examine the educational role of care pathways in elective surgical admissions during surgical internship and the effect of their introduction on interns' confidence in performing tasks. METHODS: A questionnaire survey was filled in by interns to determine their confidence in performing different tasks during elective surgical admission and postoperative care. Care pathways were then formulated for the commonest procedures within the Department of Colorectal Surgery. The same interns then repeated the same questionnaire after they were exposed to the care pathways. RESULTS: Thirty interns participated in the study with a 100% response rate. There was statistically significant improvement in tasks performed confidently in 20 out of 21 areas surveyed after the introduction of the care pathways. The percentage of tasks performed with no confidence decreased from 25% to 1% (p<0.001). CONCLUSION: Care pathways are an effective method to improve the efficiency and confidence of interns in different aspects of surgical care, thereby improving patient safety. They also function as a valuable educational tool to aid interns in the management of patients with complex surgical issues.

BACKGROUND: Vitamin E is a generic term used to describe the many derivatives of tocol and tocotrienol. It is the major lipid-soluble antioxidant in the skin and has been used as treatment for many skin conditions, including scarring. Studies have shown that vitamin E provides no benefit to the cosmetic outcome of scars. METHODS: The authors constructed and distributed a questionnaire among staff and students at their institution. Their aim was to determine patterns of use and prescription of vitamin E among staff and students and to determine the understanding of the properties and biological functions of vitamin E. RESULTS: Questionnaires were completed by 208 staff and students, including 110 nonconsultant hospital doctors (52.89 percent), 61 nurses (29.33 percent), and 27 medical students (12.98 percent). Nearly 68 percent thought that vitamin E could be of use in improving the cosmetic appearance of scars, while 25 percent actually recommended vitamin E to patients to improve the cosmetic outcome of scars. Just under 40 percent were aware of the biological function of vitamin E, while 16.35 percent thought vitamin E had absolutely no effect on scarring. Of respondents, 21.64 percent had used vitamin E for their own scars; 31.11 percent of these said it was suggested by a doctor, while 6.67 percent said a pharmacist suggested it. CONCLUSIONS: Without scientific basis, health professionals continue to recommend vitamin E for use on scars. Such recommendations should not be made in the absence of evidence-based medicine.
