Informed consent: exploring surgical residents' beliefs, attitudes and practices.

Patients rely on the knowledge and skill of the physician proposing treatment to relay information and inform their decision-making. In academic medical centres (AMCs), surgical trainees frequently request consent on behalf of an attending surgeon. There is a paucity of knowledge regarding the frequency of this practice and any associated impacts on surgical trainees.

What is the adequate margin of surgical resection in oral cancer?

Objective: The "adequate surgical margin" has always remained an enigma in the minds of head and neck surgeons. This study systematically analyses the impact of the width of the clear surgical margin on survival in oral cancer.

Study Design: A historical cohort of 277 surgically treated patients with oral cancer were followed for a median period of 36 months.

Treatment outcomes in squamous cell carcinoma of the maxillary alveolus and palate: a population-based study.

Objective: This population-based historical cohort study evaluates the treatment outcomes of primary squamous cell carcinoma of the maxillary alveolus and hard palate.

Methods: A historical cohort of 37 cases of previously untreated biopsy-proven squamous cell carcinoma of the upper jaw registered in the Province of Manitoba from January 1975 to January 2004 was analyzed.

Results: The tumor epicenter involved the maxillary alveolus in 26 patients and the hard palate in 11 patients.

Population-based study of treatment outcomes in squamous cell carcinoma of the retromolar trigone.

Background: Carcinoma of the retromolar trigone is relatively uncommon. High rates of local recurrence account for a relatively poor prognosis.

Study Design: A population-based historical cohort of 76 cases with biopsy-proven squamous cell carcinoma of the retromolar trigone were studied as a case series.

The clinical significance of the positive surgical margin in oral cancer.

The objective of surgical management of squamous cell carcinoma of the oral cavity is adequate resection with a clear margin. This study examines the significance of the positive surgical margin. An historical cohort of 425 patients from the cancer registry of the Province of Manitoba with squamous cell carcinoma of the oral cavity treated with surgery +/-radiotherapy was examined.

Accuracy of telemedicine in detecting uncontrolled hypertension and its impact on patient management.

This study was aimed at assessing the diagnostic accuracy of telemedicine among hypertensive patients. This was a cross-sectional analysis of patients attending a hypertension clinic over a year-long study. Patients were seen both by telemedicine and in-person on the same day with order of the encounters randomly determined.
