OBJECTIVE Since modern treatment of rheumatoid arthritis (RA) is shifting toward aggressive antirheumatic therapy in an early phase of the disease, diagnostic tests with high specificity are desirable. A new serologic test (anti-cyclic citrullinated peptide [anti-CCP] enzyme-linked immunosorbent assay [ELISA]) was developed to determine the presence of(More)
OBJECTIVE To develop a clinical model for the prediction, at the first visit, of 3 forms of arthritis outcome: self-limiting, persistent nonerosive, and persistent erosive arthritis. METHODS A standardized diagnostic evaluation was performed on 524 consecutive, newly referred patients with early arthritis. Potentially diagnostic determinants obtained at(More)
A double-blind, placebo-controlled study of the efficacy of LH-RH nasal spray in treatment of cryptorchidism involving 252 prepuberal boys with 301 undescended testes, showed a success rate of 9% (14 testes) for LH-RH and 8% (10 testes) for placebo. Including a subsequent open study and a second course of LH-RH as required, the rate for LH-RH rose to 18%(More)
OBJECTIVES To study the number of patients that taper or discontinue concomitant methotrexate (MTX) in daily practice in patients with rheumatoid arthritis (RA) treated with tumour necrosis factor inhibitor (TNFi) and to analyse the effects of that adaption on disease activity and drug survival. METHODS Data were collected from the Dutch Rheumatoid(More)
PURPOSE To compare the effect of delayed and early treatment strategies on disease outcome in patients with rheumatoid arthritis. SUBJECTS AND METHODS Between 1993 and 1995, 109 patients diagnosed with probable or definite rheumatoid arthritis of recent onset were initially treated with analgesics; if they had persistent active disease, they were treated(More)
Longitudinal studies on total and resting metabolic rate and total heat loss were made in 14 LBW infants, age 1-58 d. Metabolic rate was calculated from indirect calorimetry, heat loss was measured by direct calorimetry. Total metabolic rate and total heat loss were lowest during the first week of life, 178.9 +/- 18.0 and 171.8 +/- 15.5 kJ X kg-1 X 24 h-1,(More)
OBJECTIVES Experience with anti-TNF agents for a decade can be used to research the safety and effectiveness of anti-TNF agents in the long term. The objective of this article is to describe drug survival, disease activity, daily functioning, quality of life and adverse events of TNF-blocking agents in daily clinical practice after 5 years of follow-up.

In a double-blind, placebo-controlled study, 252 prepubertal boys with 301 undescended testes were treated with luteinising-hormone-releasing-hormone (LHRH), 1.2 mg/day intranasally. After the 8-week double-blind period 10 placebo-treated (8%) and 14 LHRH-treated (9%) testes had completely descended. After a second LHRH course, involving all the subjects in(More)
OBJECTIVE To determine the diagnostic and prognostic test qualities of the enzyme linked immunosorbent assays (ELISA) for rheumatoid factor isotypes in rheumatoid arthritis (RA), and to compare them with the latex fixation test. METHODS Rheumatoid factor tests were performed in 1988 consecutive new rheumatology outpatients within two months after their(More)
