Cognitive impairment in patients suffering from relapsing-remitting multiple sclerosis with EDSS ≤ 3.5
2003
Objectives – Previous papers have mainly demonstrated the presence and the frequency of cognitive impairment in patients suffering from relapsing-remitting multiple sclerosis. The purpose of this study was to investigate subjects with the relapsing-remitting form of the disease and mild clinical disability (EDSS ≤ 3.5), so as to quantify this deficit when the illness does not yet interfere with daily living and the ability to work. Methods – Fifty patients and 50 healthy controls were submitted to a wide neuropsychological battery, including Wechsler Memory Scale – I- (WMS), Benton Visual Retention Test – D- (BVRT), Raven Coloured Progressive Matrices (RCPM), Kohs’ test (KT), Judgement of L…
Auditory cortical and hippocampal local-field potentials to frequency deviant tones in urethane-anesthetized rats: An unexpected role of the sound fr…
2015
Abstract The human brain can automatically detect auditory changes, as indexed by the mismatch negativity of event-related potentials. The mechanisms that underlie this response are poorly understood. We recorded primary auditory cortical and hippocampal (dentate gyrus, CA1) local-field potentials to serial tones in urethane-anesthetized rats. In an oddball condition, a rare (deviant) tone ( p = 0.11) randomly replaced a repeated (standard) tone. The deviant tone was either lower (2200, 2700, 3200, 3700 Hz) or higher (4300, 4800, 5300, 5800 Hz) in frequency than the standard tone (4000 Hz). In an equiprobability control condition, all nine tones were presented at random ( p = 0.11). Diffe…
Vascular atherosclerotic disease: evaluation of the whole-blood filterability and red cell membrane microrheological pattern after intravenous admini…
1990
SummaryA study was carried out in 10 patients with vascular atherosclerotic disease to investigate the effects of a single dose of 300 mg pentoxifylline, given by intravenous infusion over 30 minutes, on various macrorheological and nzicrorheological parameters. Measurements were made at baseline, at the end of the intravenous infusion and again 30 minutes later of whole-blood filterability, erythrocyte membrane fluidity (using pyrene as probe) and transverse fluidity gradient (using fluorescent fatty acids as probes). The results showed that there was a significant variation in whole-blood filterability and the red cell membrane fluidity gradient after pentoxifylline. No difference, howeve…
Adjuvant Intravesical Chemotherapy in Patients with Primary T1 G3 Transitional Cell Carcinoma of the Bladder
1993
The Authors present their experience with TUR plus adjuvant intravesical chemotherapy in 50 patients affected by primary T1 G3 bladder tumours without previous or concomitant carcinoma in situ. At a mean follow-up of 36 months, 84% of the patients are alive and tumour-free. Cystectomy was performed in three patients due to locally invasive disease. Five patients (10%) died of bladder cancer.
Nonsteroid Immunosuppressants in Endocrine Orbitopathy
2009
Consensus statement of the European Group on Graves' orbitopathy (EUGOGO) on management of GO.
2008
Summary of consensus a. All patients with GO should (Fig. 1):Be referred to specialist centers;Be encouraged to quit smoking;Receive prompt treatment in order to restore andmaintain euthyroidism.b. Patients with sight-threatening GO should be treatedwith i.v. GCs as the first-line treatment; if the responseis poor after 1–2 weeks, they should be submitted tourgent surgical decompression.c. The treatment of choice for moderate-to-severe GO isi.v. GCs (with or without OR) if the orbitopathy isactive;surgery(orbitaldecompression,squintsurgery,and/or eyelid surgery in this order) should beconsidered if the orbitopathy is inactive.d. In patients with mild GO, local measures and anexpectant strate…

Regulation of Apoptosis in Endocrine Autoimmunity
2002
Dysregulation of apoptosis is associated with the pathogenesis of organ-specific autoimmune diseases, through altered target organ susceptibility. Apoptosis signaling pathways can be initiated through activation of death receptors such as Fas. A comparative analysis of the expression of Fas and FasL, the antiapoptotic molecule Bcl-2, and apoptosis in both thyrocytes and thyroid-infiltrating lymphocytes (TILs) from patients with either Graves' disease (GD) or Hashimoto's thyroiditis (HT) was performed. GD thyrocytes expressed less Fas than HT thyrocytes, whereas GD TILs had higher levels of Fas and FasL than HT TILs. GD thyrocytes expressed higher levels of Bcl-2 compared with HT thyrocytes.…
Somatostatin-Rezeptor-Szintigraphie bei endokriner Orbitopathie
1994
Somatostatin receptor scintigraphy with 111In-labeled octreotide proves to be a very sensitive diagnostic tool for evaluation of inflammative activity in endocrine ophthalmopathy (EO). The results of somatostatin receptor scintigraphy (SRS) in 40 patients with EO show a high orbital accumulation of 111In-octreotide in clinically active EO (4 h-median/orbit-brain-ratio: 12.6; controls 4 h-median: 5.8) Patients with clinically inactive EO (4 h-median: 7.1) show a similar orbital accumulation of radioactivity compared to controls. 5 patients with active orbital myositis also revealed an even higher orbital accumulation of radioactivity (4 h-median: 42.3). The diagnostic value of SRS lies in it…
