- ItemGiant peritoneal loose bodies(AOSIS Publishing, 2015-03) Van Zyl, Chris; Davis, Razaan; Hurter, Delme; Van der Westhuizen, GerhardGiant peritoneal loose bodies are rare lesions, originating from auto-amputated appendices epiploicae. They may cause urinary or gastrointestinal obstruction and, should the radiologist not be familiar with the entity, can potentially be confused with malignant or parasitic lesions. Familiarity with their characteristic computed tomographic features is essential to prevent unnecessary surgery in the asymptomatic patient. We present a case of a 70-year-old man diagnosed with two giant peritoneal loose bodies.
- ItemThe impact of the digital revolution on the SAJR(AOSIS, 2013) Davis, RazaanThank you to those members of the RSSA who participated in the recent April 2013 RSSA/SAJR poll conducted to obtain a formal record indicating their preferences when accessing journal content. Of the 213 responses, 55% indicated a preference for a digital-only format that includes online journal access and digital applications for mobile devices. Interestingly, 45% indicated a preference for the printed journal along with either online access (21%) or digital applications for mobile devices (24%).
- ItemMammography reporting at Tygerberg Hospital, Cape Town, South Africa(Health & Medical Publishing Group, 2014-07) Pitcher, Richard; Lotz, Jan; Ackermann, Christelle; Bagadia, Asif; Davis, Razaan; Du Plessis, Anne-Marie; Griffith-Richards, Stephanie; Hattingh, Retha; Wagener, Georg; Apffelstaedt, Justus; Dalmayer, Lisa; Baatjes, KarinIn their recent article, Apffelstaedt et al.[1] analysed 16 105 mammograms performed at Tygerberg Hospital (TBH), Cape Town, South Africa (SA), between 2003 and 2012. The summary reported that ‘mammograms were read by experienced breast surgeons’, while the discussion stated: ‘A further noteworthy fact is that this TBH series was based exclusively on mammography interpretation by surgeons with a special interest in breast health.’ The suggestion that mammograms were exclusively interpreted by breast surgeons does not reflect the mammography workflow at our institution.

- ItemRadiology in the research environment(AOSIS, 2013) Davis, RazaanClinicians and epidemiologists at McMaster University in Canada coined the term ‘evidence-based medicine’ in 1988.[1] The Scottish physician Dr Archibald Leman Cochrane (1909 - 1988) was a pioneer of evidence-based medicine; the Cochrane Library database of systemic reviews was named after him. Knowledge exchange occurs between researchers and the users of research, whereby research is used to change policy and planning or practice and systems. The translation of best evidence integrated with healthcare practices conduces to saving money and lives.
- ItemScholarship and the research environment(AOSIS, 2013) Davis, RazaanI recently attended a two-day course entitled ‘Postgraduate supervision in Health Sciences’ and was intrigued by the considerable number of clinical staff who were involved in demanding doctoral degree research, supervising Honours and Masters degree students. The new exit requirements from the Health Professions Council of South Africa (HPCSA), alluded to in a previous editorial, place additional demands on radiologists in university-affiliated hospitals functioning in resource-limited environments. Despite an additional limited commodity (the research supervisor), original work is consistently produced and submitted to the SAJR, and other international journals, for consideration; this is a reflection of the practitioners’ dedication to scholarship.
