Johannesburg, 2018. / Objectives Present on arrival infection is a common indication for admission in surgical patients initially managed at primary care level. We aimed to describe the demographic and disease profile of patients with infection requiring surgical management, describe determinants of patients’ health seeking behaviour and identify barriers to care. Methods A prospective descriptive questionnaire based study was conducted at Edenvale General Hospital between February 2014 and October 2016. Minors were excluded. Results Eighty nine patients participated. Abscesses (26%, 23/89), diabetic foot (22%, 20/89), and cellulitis (16%, 14/89) were the largest categories of infection necessitating admission. The majority of patients were South African (88%, 78/89), Black African (82%, 73/89), males (58%, 52/89), without medical aid (99%, 88/89), who were not formally employed (58%, 52/89), were from poor households (74%, 73/89), inhabited some form of formal housing (90%, 80/89), were in charge of decisions regarding personal health (80%, 71/89), and first sought help at the primary care level (71%, 62/89). Delay from onset of symptoms to presentation was noted in 69% (61/89) of patients, and delay from presentation to referral to specialist care in 46% (41/89) of patients. Age, race, history of diabetes, and main source of monthly income were significant variables in delayed presentation (p<0.05), and age and level of care on first contact in delayed referral (p<0.05). The most common reason for delay to presentation (84%, 51/61) and referral (61%, 25/41) was patients’ own belief that the problem would get better spontaneously. Conclusions Patients’ socio-economic status, past medical history, demographics, level of first contact with the health care system, and perceptions of their own health contributed to delays in seeking and receiving care. Barriers to care may be addressed by improvements targeting issues of availability, accessibility, acceptability and affordability of health care services. / E.K. 2019

A dissertation submitted to the Faculty of Dentistry, University of the Witwatersrand, Johannesburg, in part- fulfilment of the requirements for the Degree of Master of Science in Dentistry 1982 / Rat embryos of the post-implantation stage are grown on a static culture medium, for the purpose of assessing growth and development over a 2 day period. The technique used is referred to as the petri-dish culture chamber method. This involves the culture of rat embryos on rat serum, in a controlled environment. Postimplantation embryos from the 6,5 to 8 day stage, and consisting simply of the 3 germ layers, showed a 60% survival rate in. vit/io after 2h hours and A8 hours respectively. After a full A8 hours in vitfio the embryos demonstrated well developed beating hearts, and a neural groove in the process of closing. The survival rate of embryos explanted at later stages was not as successful. The results compare favourably with the results of other workers, using the same method of culture. An advantage of the petri-dish culture chamber is that it allows for easy experimental access to the embryos at all times;a factor to be considered in any technique involving surgical intervention. Although more sophisticated methods have since superseded the static environment petri-dish technique, it is recommended here that this method should not be totally replaced by the more modern circulating culture medium technique. / IT2017
