There are no published high-quality randomised controlled trials of the intervention, but new insights have emerged. Bacteraemic episodes are common following simple activities such as brushing teeth. Endocarditis following procedures is extremely rare, and systematic reviews of the evidence for prophylactic antibiotics have failed to demonstrate efficacy. <![CDATA[<b>Slaves of the state - medical internship and community service in South Africa</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800015&lng=pt&nrm=iso&tlng=pt Owing to a chronic shortage of medical staff in South Africa, sleep-deprived medical interns and community service doctors work up to 200 hours of overtime per month under the state's commuted overtime policy. Nurses moonlight in circumvention of the Basic Conditions of Employment Act. For trainee doctors, overtime over 80 hours is unpaid, and rendered involuntarily under threat of not qualifying to practise medicine in South Africa. As forced labour, and sleep deprivation amounting to cruel and degrading treatment, it is outlawed in international law. No other professional group in the country is subjected to such levels of exploitation and discrimination by the state. These abuses should be challenged under the Constitution. Solutions include the installation of electronic time-recording in state hospitals, cessation of unpaid overtime, limits on medical intern shifts to a maximum of 16 hours, and an investigation by the Human Rights Commission of South Africa. <![CDATA[<b>A Somalia mission experience</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800016&lng=pt&nrm=iso&tlng=pt Reports about The Horn of Africa Famine Crisis in 2011 flooded our news bulletins and newspapers. Yet the nations of the world failed to respond and alleviate the unfolding disaster. In August 2011, the Gift of the Givers Foundation mobilised what was to become the largest humanitarian mission ever conducted by an African organisation. Almost a year later, the effort continues, changing the face of disaster medicine as we know it. <![CDATA[<b>Loeys-Dietz syndrome</b>: <b>a possible solution for Akhenaten's and his family's mystery syndrome</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800017&lng=pt&nrm=iso&tlng=pt The presence of a familial disease among royal members of 18th dynasty of the new kingdom who ruled in Egypt from the mid-16th to the early 11th centuries BC has been established, largely prompted by the bizarre body shape of Akhenaten (the iconoclastic pharaoh of this dynasty) and his family, as demonstrated in statues and artwork. It had been thought previously that this was an expression of a revolutionised artistic style that followed radical reforms by Akhenaten of Egyptian society, but recent studies on mummies confirmed the presence of a constellation of corresponding pathologies. Several illnesses have been suggested to solve this enigma; we propose Loeys-Dietz syndrome as a probable diagnosis for this genetic affliction within the royal family. <![CDATA[<b>Ascites as an initial presentation of spontaneously ruptured hydatid cyst</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800018&lng=pt&nrm=iso&tlng=pt We describe the diagnosis of a 77-year-old woman admitted to our outpatient department with a 3-month history of abdominal bloating and distension. Abdominal computed tomography revealed a large cystic lesion in the posterior segment of the right hepatic lobe, with a separated germinal layer and widespread ascites with dense internal echoes and septal appearance. The result of a serum Echinococcus indirect haemagglutination test was positive and findings were indicative of the spontaneous rupture of a hydatid cyst into the peritoneal cavity without trauma. Ascites is rarely seen in the course of hydatid disease, but can result from cyst rupture into the peritoneal cavity. This should be considered in the differential diagnosis of ascites, especially in areas such as Turkey, where hydatid disease in endemic. <![CDATA[<b>Solar ultraviolet radiation exposure and human health in South Africa</b>: <b>finding a balance</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800019&lng=pt&nrm=iso&tlng=pt We describe the diagnosis of a 77-year-old woman admitted to our outpatient department with a 3-month history of abdominal bloating and distension.

One active recruitment strategy is advertisements in professional journals and other media. OBJECTIVE: To establish the trends in foreign advertisements for doctors placed in the South African Medical Journal (SAMJ) from January 2006 to December 2010. METHODS: A retrospective review was conducted of 60 issues of the SAMJ published in the preview years. Printed journals were scanned for foreign advertisements. The findings were compared with a review of 2000 - 2004 in the same journal. RESULTS: There were 1 176 foreign advertisements placed in the SAMJ in the review period, reducing from 355 in 2006 to 121 in 2010. The countries placing the most advertisements were Australia (n=428, 36.4%), Canada (n=286, 24.3%), New Zealand (n=191, 16.2%) and the UK (n=108, 9.2%). Compared with the earlier findings, there was a reduction in advertisements for the top countries, excepting Australia. The top 4 countries remained the same for the 2 review periods, but the order changed, with Australia superseding the UK. CONCLUSION: The number of foreign advertisements placed in the SAMJ declined over the period under review, and there was a change in ranking of the top 4 advertising countries. These findings are discussed from the perspective of global human resources for health initiatives. <![CDATA[<b>Osteosarcoma presentation stages at a tumour unit in South Africa</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800022&lng=pt&nrm=iso&tlng=pt BACKGROUND: Osteosarcoma is the most common malignant bone tumour found in children and adolescents. Changed treatment protocols have resulted in improved survival and the opportunity for limb salvage surgery. Despite these advances, the outcome is mainly determined by the stage of disease at presentation, making early referral to a tumour unit essential. METHODS: Between July 2009 and October 2011, 25 consecutive patients were diagnosed with biopsy-confirmed osteosarcoma. Their records were reviewed and information extracted regarding clinical presentation, histological subtype and stage of disease. RESULTS: Twenty-four patients met the inclusion and exclusion criteria. Conventional osteosarcoma was the most common histological diagnosis encountered; 16 out of 24 (66.7%) patients had metastases at presentation; 6 of the remaining had advanced local disease with very large tumours or pathological fractures that precluded limb salvage surgery. CONCLUSION: The great majority of patients referred to our tumour unit present with locally advanced or metastatic disease, which limits treatment options and adversely affects survival. Increased awareness, a high index of suspicion and appropriate early referral is crucial to enable limb salvage surgery and increase disease-free survival rates. <![CDATA[<b>Plasma sarcosine does not distinguish early and advanced stages of prostate cancer</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800023&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Diagnosis of prostate cancer by prostate specific antigen (PSA) is error-prone and cannot distinguish benign prostatic hyperplasia (BPH) from malignant disease, nor identify aggressive and indolent types. METHODS: We determined serum sarcosine (N-methylglycine) in 328 cancer patients by gas chromatography (GC)/mass spectroscopy (MS) and searched for correlations with early (stage T1/T2) and advanced (stage T3/T4) disease. RESULTS: Serum sarcosine of male control patients ranged from 1.7 umol/l to 4.8 umol/l. In prostate cancer patients, sarcosine ranged from 2.8 umol/l to 20.1 umol/l. Expressed as the sarcosine/alanine ratio, serum control values were 9.4±5.5x10-3 (mean±SD) compared with 21.6±9.0; 28.5±16.6; 22.7±7.7 and 22.2±11.0 for patients diagnosed with T1, T2, T3 and T4 prostate tumours, respectively. The small differences between T1, T2, T3 and T4 patients were not statistically significant (p=0.51). However, the conventional PSA marker significantly correlated with T stage in these patients (r=0.63; p<0.009). CONCLUSIONS: The median sarcosine/alanine ratios among patients with early and advanced prostatic cancer ranged from 21.6±9.0 to 28.5±16.6 and were fairly constant, showing no statistically significant differences between T-stages. The results are consistent with published data in urine and serum which find differences between controls and patients with metastatic prostate cancer to be small and sarcosine to be uninformative regarding prostate cancer progression. By multi-comparison of PSA with T-stages in the same group of patients, we found significant correlations confirming the well-known merits and limitations of this marker. <![CDATA[<b>Profile of cause of death assigned to adults on antiretroviral therapy in Soweto</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800024&lng=pt&nrm=iso&tlng=pt This retrospective cohort study describes causes of death in 305 patients (baseline median CD4 count from 2 943 adults on antiretroviral therapy. Acute sepsis (20%), tuberculosis (18%) and Mycobacterium avium complex (MAC) bacteraemia (14%) were the most common causes. Mortality owing to the disease was 66% for MAC bacteraemia and 23% for non-Hodgkin's lymphoma. In 37 patients dying beyond one year on ART, virological failure was present in 11 (30%), and non-HIV-related causes of death occurred in 10. The main causes were acute sepsis (6), tuberculosis (7) and chronic medical conditions (5). Initiating ART at higher CD4 counts should reduce early mortality. <![CDATA[<b>Inherited polyglutamine spinocerebellar ataxias in South Africa</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800025&lng=pt&nrm=iso&tlng=pt OBJECTIVE: To determine the frequency and distribution of polyglutamine spinocerebellar ataxias (SCAs) from referrals over a 24-year period to the National Health Laboratory Service (NHLS) in South Africa (SA). METHODS: Paper-based clinical reports in the University of Cape Town laboratory and the NHLS electronic patient record database spanning a 24-year period were mined for information regarding the molecular diagnosis, ethnicity and CAG repeat length for individuals referred for molecular genetic testing for the polyglutamine SCAs. RESULTS: SCA1 and 7 are the most frequent types of polyglutamine SCA in the SA patient population, followed by SCA2, 3 and 6. SCA1 is the most common type in the coloured, white and Indian populations, whereas the majority of indigenous black African patients are affected with SCA7 and 2. Of individuals tested, 22% were found to be positive for one of the polyglutamine SCAs. CONCLUSION: Although trends in the frequency and distribution of the polyglutamine SCAs in SA have not changed significantly since our previous study in 2003, they differ remarkably from those reported elsewhere, and reflect the unique genetic and demographic background of SA. The provision of accurate and complete patient information and family history is crucial to the diagnostic process, to enable comprehensive epidemiological studies and assist in developing therapeutic and patient management strategies. <![CDATA[<b>Traditional eye medication and pterygium occurrence in Limpopo Province</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800026&lng=pt&nrm=iso&tlng=pt BACKGROUND: The relative importance of environmental and hereditary factors in the occurrence of pterygium in African blacks has not been reported. AIM. To investigate the relative significance of factors associated with pterygium occurrence. METHODS: This was a prospective case-controlled study where 150 pterygium patients and 150 controls participated. Interviews were conducted, eyes examined and multivariate analysis done. The families of 51 pterygium cases and 50 controls were examined for presence of pterygium. RESULTS: Of 150 cases and 150 controls, 79 (52.6%) and 60 (40%) used traditional eye drops (odds ratio (OR) 2.03; p=0.009. Ten cases (6.6%) and 26 controls (17.3%) had unstable tear film (OR 0.30; p=0.007. Forty-six cases (30.6%) and 15 controls (10%) reported a positive family history (OR 3.93; p<0.001). Groups of 3 - 5 pterygium cases in a household occurred in 36 of 51 pterygium families (70.5%) v. 1 of 50 controls (2%). CONCLUSIONS: Pterygium occurrence was associated with the use of traditional eye drops, a positive family history and having groups of diagnosed pterygium-affected relatives. However, unstable tear film seemed protective against pterygium occurrence. <![CDATA[<b>Do South African universities provide the required training platforms for otolaryngology specialist training?</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800027&lng=pt&nrm=iso&tlng=pt BACKGROUND: Concern exists about the quality of specialist training platforms at South African universities and teaching hospitals. METHOD: We conducted an audit of the quality of training at South African otolaryngology (ENT) training institutions from the perspective of the registrars. RESULTS: Some institutions were deficient in terms of supervision, theatre time, access to teaching aids and research tools, and range of surgery, and do not provide the required training platforms for ENT specialist training. Five out of 8 institutions have produced <2 publications in peer-reviewed journals over the past 5 years. CONCLUSIONS: The HPCSA fails to adequately police the quality of training in South Africa. Training programme shortcomings must urgently be addressed to ensure proper education and training of otolaryngologists. <![CDATA[<b>Allergic rhinitis in South Africa</b><b>, </b><b>2012 guidelines</b>: <b>On Behalf of the South African Allergic Rhinitis Working Group</b> <b>(SAARWG)</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800028&lng=pt&nrm=iso&tlng=pt BACKGROUND: Allergic rhinitis (AR) is an important disease in South Africa. The South African Allergic Rhinitis Working Group (SAARWG) has published previous guidelines for AR diagnosis and management. Areas of concern have arisen that require additional information, including the management of AR in infancy, appropriate and inappropriate allergy testing, cost of AR management, diagnosis and distinguishing the condition from sinusitis, use of over-the-counter medications, and the concept of the 'united airway'. RECOMMENDATIONS: Clinicians should consider the possibility of AR in infants with recurrent nasal symptoms. Allergy testing should be used wisely and based on local allergens. Total IgE testing is not routinely required to prove allergy. Acute and chronic sinusitis should be considered in conjunction with AR; treatment of rhinitis will improve these conditions. Over-the-counter medications should be used sparingly and with caution. Concern for long-term use of topical decongestants must be noted. Asthma should always be considered in AR diagnosis. Immunotherapy is available in SA and may be extremely useful in selected AR patients. CONCLUSION: The SAARWG proposed an algorithm for the diagnosis and management of rhinitis in South Africa. AR is common, important and troubling to patients; therefore, every effort should be made to target therapy correctly. Patient education is important in the management of AR. <![CDATA[<b>South African guidelines for the management of Gaucher disease, 2011</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800029&lng=pt&nrm=iso&tlng=pt BACKGROUND: Gaucher disease is an autosomal recessive lysosomal glycosphingolipid storage disorder resulting from a deficiency of lysosomal enzyme acid â-glucosidase (glucocerebrosidase). This partial enzyme deficiency results in accumulation of glycosphingolipid-laden macrophages (Gaucher cells) throughout the liver, spleen, bone marrow, skeleton, lungs and brain (only in types 2 and 3). OBJECTIVE: These guidelines aim to provide a standard of care for patients with Gaucher disease in keeping with international standards, but also realistic for South Africa, and to provide a shared-care model for treating physicians and funders regarding care for these patients. RECOMMENDATIONS: All healthcare professionals involved in the diagnosis and management of Gaucher disease should take note of and implement these guidelines in clinical practice as far as possible. VALIDATION: These guidelines were developed through consensus by the Lysosomal Storage Disorder Medical Advisory Board. They are largely based on the UK 2005 National Guidelines for Gaucher Disease, but include new treatment recommendations for enzyme replacement therapy based on subsequent publications. The Southern African Society for Human Genetics (SASHG) (who have endorsed the guidelines) and the National Osteoporosis Foundation of South Africa (NOFSA) provided valuable input. GUIDELINES SPONSOR: Genzyme initiated the project and sponsored the meetings of the Advisory Board and all costs generated by these meetings. CONCLUSION: It is intended that these guidelines will enable all patients suffering from Gaucher disease to be diagnosed and offered the best possible care available. http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742012000800030&lng=pt&nrm=iso&tlng=pt
