A new microwave satellite water vapour retrieval for the polar winter atmosphere is presented. The retrieval builds on the work of Miao et al. (2001) and Melsheimer and Heygster (2008), employing auxiliary information for atmospheric conditions and numerical optimization. It was tested using simulated and actual measurements from the Microwave Humidity Sounder (MHS) satellite instruments. Groun...

Introduction To determine the clinical significance of anti-CCP (anticitrullinated cyclic peptide) in Korean patients with JRA. Rheumatoid Factor (RF) is a non-specific serologic test in juvenile rheumatoid arthritis (JRA) but the anti-perinuclear autoantibodies are found in adult rheumatoid arthritis (RA) recently. One of these autoantibodies can detect epitopes called citrulline. The authors ...

Poor adherence to medical regimens can compromise the efficacy of treatments for children and adolescents with juvenile rheumatoid arthritis (JRA). The purpose of this review is to describe medical regimens for the treatment of JRA and the rates of adherence to these regimens. We also summarize and critically the few research studies aimed at improving adherence to regimens for JRA. Finally, we...

CASE: A mother of a 2-year-old girl brings her daughter to a pediatrician for a third opinion. For the past five weeks, the girl has been feeling “not quite herself in the morning.” She has been irritable and slow to get out of bed, sometimes refusing to get up altogether, and walks more stiffly than usual. She gets better as the day goes on but worsens again after her afternoon nap, and seems ...

[Purpose] This study was conducted to assess the physical fitness of children with juvenile rheumatoid arthritis (JRA). [Subjects and Methods] In total, 26 children with juvenile rheumatoid arthritis (JRA) and 25 healthy controls participated in this study. Using the physical fitness measurement instruments, the Inbody 720 and Quark b2, the elements of physical fitness that were assessed includ...

OBJECTIVE To determine the population incidence of juvenile rheumatoid arthritis (JRA) in Quebec. METHODS We obtained data from Quebec's physician claims database. Incident cases were defined as having a visit for JRA in 2000, no visit in the previous 3 years, a confirmed diagnosis by an arthritis specialist, or having >/= 2 visits to any physician for JRA, >/= 2 months apart but within 2 yea...

OBJECTIVE to evaluate the prevalence and clinical significance of anti-chromatin antibodies (Abs) in juvenile rheumatoid arthritis (JRA). METHODS IgG anti-chromatin Abs were detected by an enzyme-linked immunosorbent assay (ELISA), in sera of 94 children with JRA (10 children with systemic, 38 with polyarticular and 46 with oligoarticular disease onset). As control group, 33 age- and-sex-matc...

The serological diagnosis of juvenile rheumatoid arthritis (JRA) is difficult, with only 7-10% of patients 19S IgM rheumatoid factor positive. About 60-70% of patients are positive for hidden 19S IgM rheumatoid factor, but this test requires serum separation and is not available in most laboratories. Antiperinuclear factor has been described in both seropositive and seronegative adult patients ...
