ABSTRACT
BACKGROUND: Alcohol use and risky drinking are significant public health problem globally. Young people, including university students, are among the most affected populations. We conducted the study to determine the prevalence and correlates of alcohol use and risky drinking among undergraduate students in the Faculty of Health Sciences at the University of the Witwatersrand, South Africa. METHODS: We conducted a cross-sectional study using an anonymous, self-administered online survey in REDCap. The survey questionnaire consisted of socio demographic, and alcohol use questions using the risky drinking identification screening tool (AUDIT-C). We performed descriptive statistics, bivariate and multivariable logistic regression to determine factors associated with alcohol use and risky drinking. The p-value of < 0.05 was considered statistically significant. RESULTS: The response rate was 15.7%. Most participants were female (69.6%) and majority of the participants were White (38.1%). The prevalence of lifetime use of alcohol was 79.1%, and among the lifetime users; 70.2% reported alcohol use in the last 12-months, 37.1% reported alcohol use in the last 30 days. The prevalence of risky drinking was 54.8% among lifetime drinkers. Factors significantly associated with current alcohol use were siblings alcohol use (aOR = 1.79, 95% CI: 1.02-3.15) and parents alcohol use (aOR = 2.58, 95% CI: 1.39-4.80), white race (aOR = 5.70, 95% CI: 3.12-10.41), and always or daily exposure to alcohol marketing in the media (aOR = 3.31, 95% CI: 1.07-10.24). Factors associated with risky drinking were: Indian/Asian race (aOR = 2.82, 95% CI: 1.09-7.31), White race (aOR = 2.15, 95% CI: 1.14-4.04), and exposure to alcohol marketing in the media as follows, most of the time (aOR = 3.42, 95% CI: 1.29-9.04) and Always/daily exposure (aOR = 3.31, 95% CI: 1.07-10.24). CONCLUSION: The reported alcohol use and risky drinking were common amongst undergraduate students at Wits university. There is an urgent need to design, pilot and adapt targeted interventions for this population group.

Anterior ankle incisions and tourniquet use in foot and ankle surgery have both been associated with increased incidence of incisional healing complications. Although a tourniquet is commonly used for procedures such as total ankle replacement and ankle arthrodesis that utilize an anterior ankle incision, it is possible to avoid tourniquet use while preserving adequate visualization with atraumatic layered dissection and closure, appropriate use of electrocautery, and ligation of vessels as needed. The primary aim of this study is to report rates of anterior ankle incisional healing complications both with and without tourniquet use. A retrospective chart review was performed on consecutive patients undergoing total ankle replacement or ankle arthrodesis through a multi-provider foot and ankle surgery practice between 2013 and 2018. A total of 121 patients, 58 (47.9%) in the tourniquet group and 63 (52.1%) in the no-tourniquet group, were included in this study with a median follow-up period of 36 (range 2-96) months. There was a higher rate of incisional healing complications for the tourniquet group (5.2%) compared to the no-tourniquet group (3.2%), however this did not reach statistical significance (p = .670). There was no significant difference in operative time between the tourniquet and no-tourniquet group (p = .405). The overall incisional healing complication rate was 4.1%. Although avoiding tourniquet use alone does not appear to significantly reduce anterior ankle incisional healing complications, the described technique has yielded an overall lower rate of incisional complications compared to those commonly reported in the literature.

Cavovarus deformity is a complicated condition most commonly resulting from neurologic, posttraumatic, or iatrogenic pathologic conditions. Careful evaluation of the cavovarus patient is necessary in determining appropriate treatment course. Weight-bearing radiographs are necessary, and advances in computed tomographic technology can be beneficial in identifying level of involvement. In the case of operative treatment of inframalleolar deformity, assessment of the subtalar joint position and relation of calcaneocuboid joint can be of assistance. Multiple osteotomies have been described providing uniplanar, biplanar, and triplanar correction and in the appropriate setting can prove beneficial to the surgeon in treating hind-foot cavovarus deformity.
