Analysis of Italian regulations on pathways of care for patients in a vegetative or minimally conscious state.

Different rehabilitation models for persons diagnosed with disorders of consciousness have been proposed in Europe during the last decade. In Italy, the Ministry of Health has defined a national healthcare model, although, to date, there is a lack of information on how this has been implemented at regional level. The INCARICO project collected information on different regional regulations, analysing ethical aspects and mapping care facilities (numbers of beds and medical units) in eleven regional territories. The researchers found a total of 106 laws; differences emerged both between regions and versus the national model, showing that patients with the same diagnosis may follow different pathways of care. An ongoing cultural shift from a treatment-oriented medical approach towards a care-oriented integrated biopsychosocial approach was found in all the welfare and healthcare systems analysed. Future studies are needed to explore the relationship between healthcare systems and the quality of services provided.

Immunosuppression in renal transplantation: viral diseases and chronic allograft nephropathy.

Chronic allograft dysfunction after renal transplantation can be ascribed to different causes, among which are viral infections. The aim of this work was to show the various ways by which different kinds of viruses affect transplant structure and function. Polyoma virus is an example of viruses directly affecting the kidney because of a specific tropism to the uroepitelial cells. Cytomegalovirus (CMV) has been chosen both because of the frequency of this infection and because CMV (as other viruses) can produce transplant vascular sclerosis. Finally, we describe hepatitis C virus (HCV) because of its capacity to induce renal lesions independently from chronic allograft nephropathy. Indeed HCV is likely to determine immunologically mediated nephritis in the transplanted kidney as well in the native one.

Limits of clinical signs and non-invasive techniques in detecting severe acute rejection.

We describe a cadaveric renal transplant patient with an early post-transplant period characterized by normal urine output, normal clinical and biological signs, and a slow decrease of serum creatinine; repeated ultrasonography, color doppler ultrasonography and renal angioscintigraphy were normal or consistent with a clinical diagnosis of mild acute tubular necrosis. Nevertheless a core renal biopsy revealed severe steroid-resistant acute rejection with diffuse infiltrates of lymphocytes and initial transmural arteritis.
