Description of six cases of child cauda equina leptomeningitis: an emerging disease

Child cauda equina leptomeningitis (CCEL) is a typical clinical example of aseptic meningitis with patterns of an emerging disease, and it affects children aged 2-9. Here we will describe six cases of CCEL. After the prodromes, all children underwent an acute phase with hypoasthenia of the lower limbs, hyporeflexia, staggering and ataxia with steppage. Only in one case there were generalized fits and coma of grade 1-2 too. All children underwent a spinal magnetic resonance imaging (MRI), proving pathologic enhancement of cauda equina and conus medullaris leptomeningitis. At the same time, MRI made possible the differential diagnosis between cauda equina leptomeningitis and isolated minor forms of Guillain-Barre syndrome involving the lower limbs. Three hypotheses will be formulated for understanding the pathogen mechanism(s) of CCEL. The first one is based on the presence of an immediate viral damage on the meninges, the second one, the more likely, contemplates the occurrence of an immunomediated mechanism in a host genetically prone to react in an abnormal way from an immune viewpoint. The third hyphotesis consists in a two-time damage: an early immediate damage from the virus, and a later immunomediated reactio

Head CT scan in emergency room: Is it still abused? Quantification and causes analysis of overprescription in an Italian Emergency Department

In recent years, the increasing prescription of diagnostic imaging has been noted, due to advances in imaging technology and the development of defensive medicine. Overuse of diagnostic imaging significantly impacts the quality and costs of health care. Therefore, the purpose of this study was to quantify overprescription and investigate its causes through the evaluation of head computer tomography (CT) scan prescriptions. In this study, a set of 100 requests of CT scans was collected and analysed by three experts in guidelines and scientific evidences, evaluating prescription appropriateness. Then, the rate of overprescription was quantified and its causes identified as incorrect adoption of guidelines indications (32%) and as defensive medicine (6%). Therefore, in order to reduce inappropriate investigations, the findings of the present study suggest that the reduction in overprescription could be reached through the improvement of training of health personnel and the propagation of a no-blame culture aimed at minimizing defensive medicine
