A 24-year-old man presented with acute pancreatitis. Serial ultrasonographic examination showed the development of bright echoes within the pancreatic parenchyma compatible with gas formation. This was confirmed on subsequent computed tomography and at laparotomy. The value of serial ultrasonographic examinations in pancreatitis is emphasized.  相似文献

In January 1989, the Johannesburg City Health Department developed an AIDS education poster. The poster was adapted from a cartoon in the Sowetan newspaper and was formally evaluated before its final production. As a result of this evaluation further editing and restructuring of the poster proved necessary. The methodology used in the evaluation is outlined, and some of the findings that emerged during the evaluation are discussed, since few formal evaluations of health education material seem to have been documented in South Africa. This study highlights the importance of formative evaluation of printed health educational media by a sample of the target audience before production and distribution.  相似文献

Renal uptake of Tl-201 reflects renal perfusion and may have a role in defining renal asymmetry in patients with hypertension who are referred for myocardial scintigraphy. The authors compared two methods of quantitating differential renal uptake of Tl-201, with similar data obtained from the angiographic and renal uptake (RU) phases of Tc-99m DTPA scintigraphy in 35 patients with hypertension. For Tl-201, asymmetry in renal counts was quantitated based on a simple outline technique or on interpolative background subtraction of 5-minute posterior images. Inter-observer and intra-observer variability among duplicate measurements were lower for Tl-201, particularly with interpolative background subtraction, than for Tc-99m DTPA. Renal/background ratios were similar for Tl-201 and RU-phase Tc-99m DTPA images when considering liver, spleen, or inter-renal regions as background; however, paraspinal uptake was relatively higher with Tl-201 (P less than 0.01). Qualitatively, renal asymmetry scores with the two radiotracers agreed (r = 0.89, blinded readings by four observers), although asymmetry was more marked with Tl-201 (P = 0.06). Measurements with Tl-201 agreed with both phases of Tc-99m DTPA (r = 0.96 to 0.98), but interpolative background subtraction systematically yielded greater inter-renal asymmetry than RU (P less than 0.01), reflecting the qualitative impression. Thus, ancillary Tl-201 imaging reflects differences between the kidneys in a fashion similar but not identical to Tc-99m DTPA scintigraphy.  相似文献

Education for and the practice of Clinical Pharmacy in South Africa have been neglected. This paper describes one attempt to improve matters. An initial survey of pharmacies, pharmacists and other staff in a small group of private hospitals determined the level of Clinical Pharmacy organization and services. The results were used to design a Clinical Pharmacy (training) Programme for selected pharmacists in the group. The programme consisted of six units, each of which was presented in at least a full-day session, with strong audiovisual support, small group discussion and rigorous exercises. During and after each session, implementation and application in the respective hospitals were monitored, as were participants' reactions. Clinical Pharmacy services increased markedly as a result of the programme, as did job satisfaction and motivation among most of the participating pharmacists.  相似文献
