Reversibility of brain lesions in a case of Neuro-Behçet's disease studied by MR diffusion.

Behçet's disease is a multisystem disorder first described in 1937 as a triad of oral and genital ulcerations and uveitis. The etiology is unknown. Involvement of the central nervous system (CNS) occurs in 10-25% of patients.

Regression of symptoms after selective iron chelation therapy in a case of neurodegeneration with brain iron accumulation.

We report the results of iron chelating treatment with deferiprone in a 61-year-old woman with signs and symptoms of neurodegeneration with brain iron accumulation (NBIA). After 6 months of therapy the patient's gait had improved and a reduction in the incidence of choreic dyskinesias was observed. Her gait returned to normal after an additional 2 months of therapy, at which time there was a further reduction in involuntary movements and a partial resolution of the blepharospasm.

Magnetic resonance spectroscopy facilitates assessment of intramyocellular lipid changes: a preliminary short-term study following biliopancreatic diversion.

Background: Intramyocellular content of lipid (IMCL) appears to be important in the pathogenesis of insulin resistance, and the improvement of insulin activity observed following biliopancreatic diversion (BPD) for obesity has to be related to reduction of IMCL. This study evaluates the possibility of detecting changes after BPD in IMCL by means of H1 magnetic resonance spectroscopy.

Methods: The investigation was carried out in obese patients undergoing BPD prior to and at 1 month following the operation.

Autologous stem cell transplantation as rescue therapy in malignant forms of multiple sclerosis.

Malignant forms of multiple sclerosis (MS) represent a limited group of very aggressive demyelinating diseases, which rapidly progress to severe disability leading often to life-threatening conditions. On these clinical entities, currently available therapies for MS are not very effective. Recently, it has been demonstrated that intense immunosuppression followed by autologous stem cell transplantation (ASCT) can affect the clinical course of individuals with severe MS and completely abrogate the inflammatory activity detected by magnetic resonance imaging (MRI).

Measures of late effects in conservative treatment of breast cancer with standard or hypofractionated radiotherapy.

Aims And Background: To confirm the equivalence in terms of late effects between two fractionation schedules of radiotherapy in conservative treatment of breast cancer.

Methods: Fifty-eight patients treated at our institution from 1999 to 2002, with a median follow-up of 15 months (range, 7-46 months), were evaluated retrospectively. Twenty-nine patients (group A) were treated with standard fractionation: 5000 cGy/25fx/5 weeks, and 29 patients (group B) were treated with a hypofractionated schedule: 4500 cGy/15fx/5 weeks, three fractions per week.

Growing Region Segmentation Software (GRES) for quantitative magnetic resonance imaging of multiple sclerosis: intra- and inter-observer agreement variability: a comparison with manual contouring method.

Lesion area measurement in multiple sclerosis (MS) is one of the key points in evaluating the natural history and in monitoring the efficacy of treatments. This study was performed to check the intra- and inter-observer agreement variability of a locally developed Growing Region Segmentation Software (GRES), comparing them to those obtained using manual contouring (MC).
