Difficult diagnosis of infliximab-related miliary tuberculosis
No full textDifficult diagnosis of Infliximab-related miliary tuberculosis. S. Contini, G. Raimondi, P. Graziano, C. Saltini, M. Bocchino. The use of Infliximab in the treatment of patients with rheumatoid diseases unresponsive to conventional therapies has been reported to be complicated by opportunistic infections. We report the case of a 56-yr old female rheumatoid arthritis patient complaining of fever and respiratory symptoms 9 months after commencing Infliximab, who received no ethiologic diagnosis for the six months before admission. Tuberculosis was suspected upon chest radiographic pictures and empirical treatment for miliary tuberculosis instated in the wake of microbiological confirmation. The case typifies the difficulties of diagnosing miliary tuberculosis in the immunocompromised as well as in the immunocompetent patient

Neural Petri Control: an application on a mobile robot
No full textIn the present work, an innovative nonlinear controller of nonholonomic mechanical systems, characterized by a dynamic not well known model a priori, using a new neural model obtained by the combination of a Petri net with a neural network, is proposed. The performances of the control algorithm are evaluated for tasks of tracking of time trajectories. The study of the stability of the total system to closed loop is based on the Lyapunov theory. Simulation experiments, made taking into consideration a nonholonomic mobile robot, to two wheels, allowed to verify the theoretical results
Vertebral rotation in adolescent idiopathic scoliosis calculated by radiograph and back surface analysis-based methods: Correlation between the Raimondi method and rasterstereography
No full textPurpose: The aim of the present research is to evaluate the relationship between an X-ray-based method (i.e. The Raimondi method) and rasterstereography in the evaluation of vertebral rotation (VR) in a sample of adolescent idiopathic scoliosis (AIS) patients. Methods: A total of 25 patients (9 males; mean age 14 ± 3 years; mean height 160.7 ± 11.9 cm; mean weight 52.4 ± 10.7 kg) were considered for the present analysis. The mean Cobb angle was 30 ± 9. The evaluation of VR on radiographs was made using the Raimondi method regolo (Marrapese Editore - Demi S.r.1., Rome). Rasterstereography was performed by means of Formetric 4D® (Diers International GmbH, Schlangenbad, Germany). Correlations between rasterstereographic and radiographic measurement of VR were calculated, both for the whole sample and for thoracic and lumbar spinal segments considered separately, as well as for subgroups of patients with a Cobb angle <30 and ≥30 using Spearman's correlation coefficient by rank (r s). Results: When applied to the entire spine, measurement of VR by means of the two methods highlighted a significant correlation in the whole group (r = 0.52; p < 0.0001), as well as in the <30 Cobb (r = 0.47; p = 0.0001) and ≥30 Cobb (r = 0.42; p < 0.0001) subgroups. A significant correlation was found also when lumbar and thoracic VR were considered as separated groups (r = 0.30, p = 0.024 and r = 0.47, p = 0.002, respectively). Conclusions: Rasterstereographic evaluation of VR shows a good correlation with the Raimondi method, thereby confirming the possibility to use this non-invasive method for deformity assessment in AIS patients. © 2012 Springer-Verlag Berlin Heidelberg

Coherent transport in disordered metals: zero dimensional limit
No full textWe consider non-equilibrium transport in disordered conductors.
We calculate the interaction correction to the current for a short wire connected
to electron reservoirs by resistive interfaces.
In the absence of charging effects we find a universal current-voltage-characteristics.
The relevance of our calculation for existing experiments is discussed as well
as the connection with alternative theoretical approaches
Coherent transport in disordered metals out of equilibrium
No full textWe derive a formula for the quantum corrections to the electrical current for
a metal out of equilibrium. In the limit of linear current-voltage characteristics
our formula reproduces the well known
Altshuler-Aronov correction to the conductivity of a disordered metal.
The current formula is obtained by a direct diagrammatic
approach, and is shown to agree with what is obtained within the Keldysh formulation
of the non-linear sigma model.
As an application we calculate the current of a mesoscopic wire.
We find a current-voltage characteristics that scales with eV/kT, and calculate
the different scaling curves for a wire in the hot-electron regime and in the
regime of full non-equilibrium
