ABSTRACT
Introduction:Simulation-based learning affords participants the opportunity to practice high-acuity, low-incidence situations without risk to the patient. The realism of a simulated scenario is often referred to as fidelity. High levels of fidelity imply high levels of realism. One method of enhancing fidelity is the use of moulage. Commercially available moulage kits and professionally applied moulage are often expensive and therefore not practical in the resource-constrained environment. Cost-effective alternatives are required for the resource-constrained environment.Methods:Students at a South African university used readily available, low cost materials to apply self-constructed, low cost moulage for a bandaging practical. A cross sectional design used a purpose-designed, validated questionnaire to gather data related to face and content validity of the self-constructed moulage. Frequency analysis formed the cornerstone of Likert-type quantitative data analysis. An open-ended question afforded participants the opportunity to express their own opinions related to the moulage experience.Results:The results revealed that there was both high face validity and high content validity of the self-constructed moulage. Participants found the activity enjoyable and a generally positive learning experience. The self-constructed moulage was realistic and added to the fidelity of the scenario. Participant confidence was improved and their engagement in the learning activity was enhanced. Participants found the self-constructed, low-cost moulage more realistic that commercial products that they had been exposed to.Conclusion:The use of low-cost, self-constructed moulage is a feasible and economically viable means of enhancing fidelity within the resource-constrained simulation setting. This technique is not necessarily limited to emergency medical care and can be used in other areas of healthcare simulation

Objective: The abnormalities that predispose to torsion are often bilateral. They include horizontally lying testis; bell-clapper deformity (BCD); long mesorchium; well-developed spiral cremasteric muscle and ectopic testis. The pattern and incidence of intrascrotal anomalies that predispose to testicular anomalies in Nigerians have not been studied. Our objective was to define and document this. Material and Methods: The scrotal sacs of fifty cadaver scrotums and inguinal canals from patients aged between 35 and 57 years (mean age: 42 years) were examined. The parameters studied were the location (scrotal or canalicular); alignment (horizontal; vertical); mesorchium (height and width); cremasteric muscle development (well or poorly developed) and parietal tunica vaginalis investment of the testis (normal; intermediate or BCD). Results: Forty-nine testes had descended to the scrotal position; all were anchored by the ligamentum testis. The canalicular position was noted to be present in one cadaver. Forty-eight testes lay vertically. 16of the testes had BCD; while intermediate tunica investment was noted in 12. The most common type of epididymal and testicular relationship was Type I (84). The mesorchium was normal in all specimens examined. Conclusion: The most common anomaly in our study was that of tunica investment; and this is usually bilateral. The need for bilateral orchiopexy in cases of testicular torsion is further strengthened since the anatomic anomalies are usually bilateral
