In a recent issue of the Annals our group reported the cases of two HLA-B27 positive patients who developed peripheral arthritis immediately after a significant traumatic episode.1 Unlike previously reported cases of HLA-B27 associated peripheral arthritis triggered by trauma24 they showed a rapid, severe destructive process. In the past few months both patients have had total hip replacement. ...

studying crustal and upper mantel structures has been limited in the iranian plateau and there has been little work done in this field. in this paper we have a primary motive to map pn and sn velocities beneath most of the iranian plateau in order to test 3-d mantle models and to develop and test a method to produce pn and sn travel time correction surfaces that are the 3-d analogue of travel t...

OBJECTIVE To compare the prevalence and type of human papillomavirus (HPV) infections in the genital tract of human-immunodeficiency-virus- (HIV) seropositive and -seronegative women matched for cytology and to examine prospectively the relationship of HPV DNA, colposcopic findings and cervical squamous intraepithelial lesions (SIL) in these matched seropositive and seronegative cohorts. METH...

We performed a prospective, randomized trial in CMV seronegative marrow recipients to determine if filtered blood products were as effective as CMV-seronegative blood products for the prevention of transfusion-transmitted CMV infection after marrow transplant. Before transplant, 502 patients were randomized to receive either filtered or seronegative blood products. Patients were monitored for t...

BACKGROUND Remitting seronegative symmetrical synovitis with pitting edema syndrome is characterized by symmetrical synovitis with pitting edema in the dorsum of the hands or feet. Most cases of remitting seronegative symmetrical synovitis with pitting edema syndrome are idiopathic, but some are secondary to malignancy, autoimmune disease, or neurodegenerative disorders. Pleural and pericardial...

Seronegative spondilo-arthropathies are characterized by particular clinical features such as sacroileitis, spondylitis and asymmetric peripheral arthritis mainly involving the lower limbs and negative rheumatoid factor. In most cases, they are associated with the HLA class I antigen B 27 (1). We have recently reported that in few selected cases of seronegative arthritis, articular symptoms may...

BACKGROUND Human herpesvirus 8 (HHV-8), cytomegalovirus (CMV) and Epstein-Barr virus (EBV) are prevalent in Africa, but less common elsewhere and the modes of transmission are still subject to debate. Generally, they rarely cause disease in the immunocompetent host but are highly oncogenic when associated with immunosuppression. Although the high prevalence of HHV-8, CMV and EBV has been well d...

Seven sporadic cases of ;seronegative glandular fever' have been examined in detail; five of the patients were adults aged more than 30, two were children. None showed evidence of ;incomplete' or heat-labile sheep cell agglutinins, but in three very weak, though otherwise typical, glandular fever agglutinins were detected. Three of the other four showed evidence of certain infections, but these...
