OBJECTIVE To evaluate in a large group of scleroderma patients, the association of nailfold videocapillaroscopic patterns with both demographic and clinical features. METHODS One hundred and three Italian patients (91 women and 12 men, mean age 54.3 years, median disease duration 7 yrs, 68 with limited and 35 with diffuse subset of disease), consecutively enrolled for the study, underwent nai...

Systemic sclerosis (SSc) can be a devastating disease with lethal complications such as interstitial lung disease (ILD). Therapeutic strategies include cyclophosphamide but patients are frequently refractory even to this aggressive immunosuppressant. Lafyatis et al published a 6-month open observational study of 15 patients with diffuse scleroderma receiving one course of rituximab (2 1 g withi...

Both cutaneous and mucocutaneous leishmaniasis are endemic in Northern Ethiopia. The different clinical presentations depend on the responsible organism and the host's immune response. Localized cutaneous leishmaniasis is the type most frequently seen. Diffuse cutaneous leishmaniasis is relatively rare and usually associated with mucous membrane involvement. Diffuse cutaneous leishmaniasis pres...

The prototypic autoimmune diseases involving skin (lupus, dermatomyositis) typically result in epithelial injury and autoantibodies to characteristic cellular antigens. Disease-specific autoantibodies are also found in scleroderma, but scleroderma is different from other cutaneous autoimmune diseases because epithelial injury does not occur. Multiple factors and combinations of factors (immune ...

We ask whether it is possible to predict the efficiency of a new dye in dye sensitized solar cells (DSSCs) on the basis of the known performance of existing dyes in the same type of device. We evaluate a number of computable predictors of the efficiency for a large set of dyes whose experimental efficiency is known. We have then used statistical regression methods to establish the relation betw...

We report a pump-probe spectroscopy study of electron injection rates in dye-sensitized solar cell (DSSC) devices. We examine the case of working devices employing an N719 ruthenium sensitizer and an iodide electrolyte. Electron injection is found to occur mainly on a sub-100 fs time scale, followed by a slower component with a lifetime of 26.9 ps, in accordance with previous reports on model s...

BACKGROUND Systemic sclerosis (SSc) is a chronic disease with microvascular damage. Nailfold capillaroscopy is a non-invasive method used for evaluating capillaries in SSc. Its findings could be related to the internal organ involvement and SSc course. In this study, we aimed to determine the association of the capillaroscopic patterns of nailfold capillaries with the disease subtypes of SSc, d...

Department of Clinical Immunology and Rheumatology, Sahara Hospital, Lucknow, India, 226010 [email protected] Scleroderma or progressive systemic sclerosis is diagnosed clinically by typical features of skin thickening, Raynaud’s phenomenon and visceral organ involvement, and serologically by distinct autoantibody subsets. These differentiate the disease into the ‘limited’ and ‘diffuse’ vari...
