General surgery in crisis--the critical shortage.

INTRODUCTION: General surgery is facing a serious crisis. There has been a significant decline in the number of applicants for registrar posts and an inability to attract and retain general surgical specialists in the state sector. The Association of Surgeons of South Africa (ASSA) undertook this study to determine the extent and cause of the problem. METHODS: The study involved a combination of desk research and structured interviews. In addition, the Health Professions Council of South Africa (HPCSA) database was reviewed and compared with the South African Medical Association (SAMA) and ASSA databases. The medical schools provided information about student numbers and demographics, and the National Department of Health pro vided information about the status of medical practitioner and specialist posts in the state sector. RESULTS: Overall, 26.1% of the specialist posts were vacant. The situation was particularly critical in Mpumalanga and the Eastern Cape, where 84% and 58% of the specialist posts were vacant. Using a predictive model, a conservative estimate of the need for general surgeons was found to be at least 50 per year. Currently the eight medical schools graduate about 25 general surgeons per year. The changing demographics of medical students may be partly responsible for the decline in registrar applicants. CONCLUSION: The findings from this study have revealed that the shortage of general surgeons in the state sector has reached critical levels.

General surgery in crisis--comparatively low levels of remuneration.

INTRODUCTION: Several factors, including comparatively low remuneration, may be responsible for the decline in applicants to general surgery. In this study, the levels of remuneration of general surgeons in the state sector were compared with other professionals in the state sector and general surgeons overseas. METHODS: The study involved a combination of desk research and structured interviews. The Paterson system of job evaluation was used to compare general surgeons with other professionals. The levels of remuneration of general surgeons in the state sector were compared with those of other professionals. RESULTS: There was a significant difference in the levels of remuneration between state-employed medical practitioners and other professional positions such as legal professionals, municipal managers and airline pilots. At senior levels (senior specialist) the remuneration was only +/- 55% of that paid to the selected comparator group. There was also a significant differential between the remuneration of state-employed general surgeons and their overseas counterparts. CONCLUSION: Levels of remuneration of state-employed medical practitioners continue to lag behind other professionals.

General surgery in crisis--factors that impact on a career in general surgery.

INTRODUCTION: The Association of Surgeons of South Africa (ASSA), because of a concern about the decline in the number of applicants for registrar posts, undertook this study into the various factors that may influence the choice of surgery as career option. METHODS: The study involved a combination of desk research and structured interviews with heads of departments, specialists, and registrars in general surgery. RESULTS: The reasons for choosing general surgery as a career included the immediately visible results of a surgeon's efforts and the practical and intellectual challenge of the specialty. General surgery continued to enjoy a high status in society. The greater focus on primary health care has affected facilities at tertiary and secondary institutions. General surgeons worked excessively long hours, which was associated with increased levels of stress and placed severe strains on family life. All respondents felt that their levels of remuneration were 'poor' in relation to other disciplines and professions. CONCLUSION: In this study we identified various factors that impacted either positively or negatively on the choice of general surgery as a career option.

Experience with the holmium laser as an endoscopic lithotrite.

INTRODUCTION: Holmium laser lithotripsy represents an additional option in the management of urinary tract calculi. We report the results of a cohort of patients with ureteric and bladder calculi treated with this modality. METHODS: Twenty-three patients underwent holmium laser lithotripsy to treat ureteric or bladder calculi. Power settings of 0.5 J to deliver 2.5-4.0 watts were used for the ureteric calculi, and up to 30 watts for the bladder calculi. RESULTS: The mean ureteric stone size was 7.3 mm (range 4-10 mm). One stone was upper ureteric, seven were mid-ureter and nine were lower-ureter. Eighteen of the 19 patients with ureteric calculi were free of stones 28 days postoperatively. The remaining patient was clear by 12 weeks. All patients with bladder calculi were completely cleared of stones. There were no intraoperative complications. DISCUSSION: Ureteric stone position can limit the use of extracorporeal shock wave lithotripsy due to imaging difficulties. Ureteric lithotripsy overcomes this problem. The holmium laser has proven to be safe and effective in clearing urinary stone burdens of a variety of sizes, sites and compositions in this cohort of patients.

Effects of cytochalasins B and D and colchicine on migration of the corneal epithelium.

Rat corneas with fresh, 3 mm central epithelial abrasions were excised and allowed to heal in organ culture. At the time of initiation of culture or after 12 hr in vitro, cytochalasin B, cytochalasin D, or colchicine was added to the medium. All concentrations of cytochalasins used reversibly inhibited both initiation and continuation of epithelial cell movement; colchicine did not. This study indicates that actin filament function is necessary for epithelial cell motility whereas microtubules are not.
