Objective: This study aims to provide a description of real life treatment patterns of biologic anti-TNF in 23 Italian Rheumatology centers.Methods: This was an observational, multicenter, retrospective study. Patients above 18 years of age, diagnosed with rheumatoid arthritis and treated with the first biologic anti-TNF agent between the 1st July 2002 to the 31st March 2004 were included. Total follow-up was 36 months. Results: In total, 248 patients were first treated with inftiximab, 259 with etanercept and 196 with adalimumab. First course of therapy with inftiximab was associated with lower cumulative drug survival than the other two agents. At 36 months, 74.7% of patients on etanercept, 72.0% of those on dalimumab and 57.7% of subjects receiving inftiximab were still on therapy. In total, 149 patients switched to a second anti-TNF agent. At 24 months of the second line treatment, 75%, 22%, and 54% of inftiximab, etanercept and adalimumab recipients, respectively, had discontinued their second anti-TNF. Conclusions: Anti-TNF agents may be associated to a rather high incidence of discontinuation and dose adjustments over a 36-month period, with a possible effect on healthcare expense. In particular, inftiximab was associated with a higher incidence of discontinuations compared with etanercept and adalimumab.

Neurofibromatosis type 1 (NF1) is caused by mutations of the NF1 gene and is one of the most common human autosomal dominant disorders. The patient shows different signs on the skin and other organs from early childhood. The best known are six or more caf au lait spots, axillary or inguinal freckling, increased risk of developing benign nerve sheath tumours and plexiform neurofibromas. Mutation detection is complex, due to the large gene size, the large variety of mutations and the presence of pseudogenes. Using Ion Torrent PGM Platform, 73 mutations were identified in 79 NF1 Italian patients, 51% of which turned out to be novel mutations. Pathogenic status of each variant was classified using American College of Medical Genetics and Genomics guidelines criteria, thus enabling the classification of 96% of the variants identified as being pathogenic. The use of Next Generation Sequencing has proven to be effective as for costs, and time for analysis, and it allowed us to identify a patient with NF1 mosaicism. Furthermore, we designed a new approach aimed to quantify the mosaicism percentage using electropherogram of capillary electrophoresis performed on Sanger method.

Tumornodemetastasis (TNM) stage I colorectal cancer is commonly characterized by a good prognosis, with 5-year survival around 8090%; nonetheless, it undergoes disease progression in a percentage of cases, although the causes of adverse clinical course still remain to be elucidated. In the present study, we analyzed and compared the immunohistochemical expression of the proangiogenic vascular endothelial growth factor (VEGF) as well as the microvessel density (MVD) in a series of 27 surgically resected colorectal carcinomas obtained from patients deceased because of disease progression and in a cohort of 25 colorectal cancers from patients still alive with no evidence of disease progression 5 years after the initial diagnosis. The prognostic value of VEGF expression and of MVD on the overall survival to colorectal cancer was investigated. A variable VEGF immunoexpression was demonstrated in all the analyzed cases. High VEGF expression was significantly more frequent among patients deceased of the disease. These patients also displayed significantly higher MVD counts in their cancer in comparison to the patients alive after 5 years from surgery. Moreover, both high VEGF expression and MVD appeared as significant negative prognostic markers related to a shorter overall survival to stage I colorectal carcinoma, with VEGF representing an independent variable at multivariate analysis. VEGF assessment might be used in order to select those patients with a higher progression risk and to submit them to adjuvant therapies useful to prevent adverse outcome. © 2010 Springer-Verlag.

Aims: The aim of our study was to assess the two-dimensional carotid strain as an index of arterial stiffness in a population of patients without carotid atherosclerotic plaques. Methods: Two-dimensional carotid strain, carotid intima-media thickness (CIMT), stiffness index (β), Peterson's elastic and results modulus, and distensibility coefficient were evaluated in 47 patients. For all patients, cardiovascular risk scores were calculated. Peak systolic circumferential strain was significantly correlated with conventional indices of arterial stiffness and with the CIMT. Peak systolic circumferential strain adjusted for pulse pressure was the only parameter that showed a significant difference between the three cardiovascular risk groups in which patients were classified. Two-dimensional carotid strain showed an excellent reproducibility. Conclusion: The two-dimensional strain allows the assessment of carotid arterial mechanics. Probably the assessment of arterial stiffness allows a better risk stratification of patients. © The Author 2011.

One large group of hereditary myopathies characterized by recurrent myoglobinuria, almost invariably triggered by exercise, comprises metabolic disorders of two main fuels, glycogen and long-chain fatty acids, or mitochondrial diseases of the respiratory chain. Differential diagnosis is required to distinguish the three conditions, although all cause a crisis of muscle energy. Muscle biopsy may be useful when performed well after the episode of rhabdomyolysis. Molecular genetics is increasingly the diagnostic test of choice to discover the underlying genetic basis. © 2015, Springer Science+Business Media New York.

The neuromasts of the lateral line system are regarded as a model to study the mechanisms of hearing, deafness, and ototoxicity. The neurotrophins (NTs), especially brain-derived neurotrophic factor (BDNF), and its signaling receptor TrkB are involved in the development and maintenance of neuromasts. To know the period in which the BDNF/TrkB complex has more effects in the neuromast biology, the age-related changes were studied. Normal zebrafish from 10 to 180 days post-fertilization (dpf), as well as transgenic ET4 zebrafish 10 and 20 dpf, was analyzed using qRT-PCR, western blot, and immunohistochemistry. BDNF and TrkB mRNAs followed a parallel course, peaking at 20 dpf, and thereafter progressively decreased. Specific immunoreactivity for BDNF and TrkB was found co-localized in all hairy cells of neuromasts in 20 and 30 dpf; then, the number of immunoreactive cells decreased, and by 180 dpf BDNF remains restricted to a subpopulation of hairy cells, and TrkB to a few number of sensory and non-sensory cells. At all ages examined, TrkB immunoreactivity was detected in sensory ganglia innervating the neuromasts. The present results demonstrate that there is a parallel time-related decline in the expression of BDNF and TrkB in zebrafish. Also, the patterns of cell expression suggest that autocrine/paracrine mechanisms for this NT system might occur within the neuromasts. Because TrkB in lateral line ganglia did not vary with age, their neurons are potentially capable to respond to BDNF during the entire lifespan of zebrafish. © Springer Science+Business Media, LLC 2010.

Oral cavity infection by protozoarian agents may lead to pathologies such as stomatitis and gengivitis. An higher incidence has been reported in immunocompromised patients and in patients with dental disorders. Entoameba gingivalis localizes into oral cavity and in particular into interstitial and interdental spaces. Infection propagation to bronchial or lung parenchyma represents a complication. In this report the Authors, starting from a recently treated case, discuss on the incidence, complications and surgical management of lung infection by Entoameba gingivalis.

Agmatine is a novel neuromodulator that plays a protective role in the CNS in several models of cellular damage. However, the mechanisms involved in these protective effects in neurodegenerative diseases are poorly understood. Fourier transform infrared (FTIR) spectroscopy analysis detects biomolecular changes in disordered cells and tissues. In this report, we utilize FTIR spectroscopy to characterize the changes in rotenone-induced damage in neuronal-like differentiated SH-SY5Y neuroblastoma cells in the presence or absence of agmatine. The analysis of the FTIR spectra demonstrates significant alterations in rotenone-treated cells, whereas the FTIR spectra obtained after pre-incubation with agmatine (250 nM) significantly reduces these redox alterations and more closely resembles those of the control cells. In particular, rotenone-damaged cells demonstrate spectral alterations related to amide I, which correspond to an increase in β-sheet components, and decreases in the amide II absorption intensity, suggesting a loss of N-H bending and C-N stretching. These alterations were also evident by Fourier self-deconvolution analysis. Thus, rotenoneinduced increases in the levels of stretching vibration band related to the protein carboxyl group would account for a significant amount of misfolded proteins in the cell. Agmatine effectively reduces these effects of rotenone on protein structure. In conclusion, antioxidant and scavenging properties of agmatine reduce rotenone-produced cellular damage at the level of protein structure. These, together with other previous observations, demonstrate the therapeutic potential of agmatine in the treatment of Parkinson's disease. © Springer-Verlag 2011.

Herpes simplex virus type 2 (HSV-2) is responsible of the continuously increasing viral infections in humans. In a previous study we demonstrated that the exopolysaccharide produced by Bacillus licheniformis strain B3-15 (EPS-B3-15), was able to hinder the HSV-2 replication in peripheral blood mononuclear cells (PBMC) and this antiviral activity appear to be related to a significant stimulation of the Th1-cytokines. In this study we analyse the role of EPS-B3-15 on Th2 cytokine production by PBMC infected or not with HSV-2. EPS-B3-15 demonstrate the ability to induce a particular cytokine network with consequent effects on the immune cells during HSV-2 infection. Copyright © Taylor & Francis Group, LLC.

The aim of this study was to compare the results of complex aneurysm (hostile neck anatomies) repair in high-risk patients with two minimally invasive techniques, fenestrated endografting (f-EVAR where EVAR stands for endovascular aneurysm repair) and minilaparotomy.All high-risk patients (N.=50, group 1) with hostile neck abdominal aortic aneurysms (AAAs) operated in the vascular surgery department of the Policlinico Universitario G. Martino of Messina (Italy) during a 5-year period (January 2006-December 2010) were cross-matched with 50 similar patients (group 2) treated in the Vascular Surgery Department of the Hopital Cardiologique University of Lille (France) with similar anatomies, comorbidities and risk factors. The patients in group 1 underwent open minilaparotomy surgery, and the patients in group 2 were treated with f-EVAR. The aim of our study was to compare perioperative complications, survival and reintervention rates.Perioperative cardiac complications occurred in 5 patients (10%) in group 1, and 1 patient (2%) in group 2 (P<0.092). Renal impairment not requiring permanent hemodialysis was significantly higher in group 1 (14% vs. 2% P<0.027), as well as respiratory complications (32% vs. 2% P<0.0001). Five patients (10%) in group 1 underwent reintervention vs. 4 patients in group 2 (P<0.7268). There was no statistically significant difference for survival rates at 30 days (92% in group 1 and 96% in group 2; P=0.399); at six months (90% vs. 96%; P=0.239); at one year (90% vs. 96%; P=0.239); and at two years (84% vs. 94%; P=0.110). However, we observed statistically significant differences in survival rates at three years (74% vs. 94%; P<0.006); at four years (70% vs. 86%; P<0.005); and at five years (65% vs. 68%; P<0.003).Our results showed that both techniques are effective in the treatment of AAA with hostile neck in high-risk patients. Although operative mortality rate was not statistically different, f-EVAR showed better results in terms of early complications and late survival.
