RESUMEN
Medical errors during surgery are usually under-reported and not well studied. During the past decade, increased interest in medical malpractice has been shown by both the public and the authorities. A particularly high risk of medical errors is seen in emergency settings, unexpected change in procedure, or in patients with a high body mass index. Visually or acoustically controlled monitoring before wound closure are recommended to eliminate human error as thoroughly as possible. Prevention remains the key to solving the problem.

BACKGROUND: Erectile dysfunction is a common and potentially treatable problem. Other than psychological, anatomical and metabolic factors, vasculogenic causes also play an important role in erectile dysfunction. Among the various diagnostic tools available for the diagnosis of vasculogenic causes, colour Doppler sonography is noninvasive, simple and promising. METHODS: This preliminary prospective study was conducted on 40 patients with erectile dysfunction, coming from a rural background to a hospital situated in a semi-urban setting. RESULTS: It was found that a cut-off value of 10 cm/second for peak systolic velocity in flaccid penis had the best accuracy among three chosen cut-off values, i.e. 5, 10, 15 cm/second, for detecting arterial insufficiency with sensitivity of 94.1%, specificity of 93.6%, negative predictive value of 98% and positive predictive value of 80%. CONCLUSION: Doppler sonography may be used as a good predictor of clinical response to intracavernosal injection of a vasodilating pharmacological agent.

Postoperative retained surgical sponges or other foreign bodies are usually underreported. Radio-opaque materials are usually detected on follow-up radiological investigations, but radiolucent materials such as sponges create diagnostic problems and clinically mimic various abdominal pathologies. Introduction of spiral computed tomography, magnetic resonance imaging and dedicated ultrasonography has enabled clinicians to find these foreign bodies at the earliest opportunity to avoid disastrous complications. Spontaneous transmural migration and expulsion per rectum of more than one sponge without sequelae is also possible. We report one such interesting case.
