Uveitis occurs among children suffering from juvenile chronic arthropathy (mainly in daughters presenting with the pauciarticular form and accompanied by antinuclear antibodies) and among adults in the group of seronegative spondylarthropathies, among which ankylosing spondylitis and Reiter's syndrome are the most representative diseases. The association between acute anterior uveitis, HLA B27 ...

We reviewed the historical, clinical and etiological aspects of the progressive chronic spastic myelopathies of unknown etiology, disserting on the clinical similarities between HTLV-I seropositive and seronegative tropical spastic paraparesis (TSP), as well as focusing on the PCR studies of the seronegative TSP.

Background The nervous system is affected in a relevant number of patients with antiphospholipid syndrome (APS), being responsible for high morbidity and mortality rates. identification neurological manifestations crucial since those symptoms may benefit from anticoagulation treatment. Noteworthy, the prevalence characteristics subset “seronegative APS” (SN-APS) still need to be investigated. O...

HLA typing was carried out in 132 patients with rheumatoid arthritis (RA) with long term follow up, and special attention was focused on rheumatoid factor negative patients. The patients were divided into four groups: 55 patients with a seropositive RA and a positive antiperinuclear factor (group A); 39 seropositive patients but a negative antiperinuclear factor (group B); 14 patients consisten...

Sn-Bi solder with different Bi content can realize a low-to-medium-to-high soldering process. To obtain the effect of Bi content in Sn-Bi solder on the microstructure of solder, interfacial behaviors in solder joints with Cu and the joints strength, five Sn-Bi solders including Sn-5Bi and Sn-15Bi solid solution, Sn-30Bi and Sn-45Bi hypoeutectic and Sn-58Bi eutectic were selected in this work. T...

The authors estimated the rates of development of serum antibodies against Brucella abortus, between January 1987 and December 1990, in female Jersey cattle and buffalo weaned from seropositive and seronegative dams, and used logistic regression analysis to examine the epidemiological relationship of these rates with the serum antibody status of dams. The offspring from both seropositive and se...

PURPOSE To investigate the outcome of HIV-seropositive patients under highly active antiretroviral treatment (HAART) with anal cancer treated with radiotherapy (RT) alone or in combination with standard chemotherapy (CT). PATIENTS AND METHODS Clinical outcome of 81 HIV-seronegative patients (1988-2003) and 10 consecutive HIV-seropositive patients under HAART (1997-2003) that were treated with...
