The General Practice Research Club was established in 1969, and now has 120 members. A meeting of the club is held twice a year, at which various papers, from research ideas through to completed, published studies are presented. A survey of 40 individuals who had presented papers at meetings during the period 1984-89 showed that almost half (18) had presented papers on clinical topics. As a result of the presentation, 29 individuals had modified their research, with 11 undertaking major alterations. The meeting was rated most highly by those offering ideas and plans for research. Most individuals responded positively to the meetings, commenting that they valued peer review, found the meetings encouraging, and useful for focusing ideas. Lack of criticism and feedback was commented upon. The club has an important role to play in encouraging research by service general practitioners. 相似文献

Chronic recurrent multifocal osteomyelitis and psoriasis—A report of a new association and review of related disorders 总被引:3,自引:0,他引:3
Ronald M. Laxer MDCM FRCPC Assistant Professor Abraham D. Shore MD FRCPC Assistant Professor David Manson MD Chief Resident Susan King MD FRCPC Fellow Earl D. Silverman MD FRCPC Assistant Professor Dan M. Wilmot MD FRCPC Assistant Professor 《Seminars in arthritis and rheumatism》1988,17(4):260-270
In summary, we have described two patients with CRMO and psoriasis, and have reviewed the musculoskeletal manifestations associated with pustular eruptions of the palms and soles. In view of the frequent occurrence of PPP in patients with CRMO, we suggest that the occurrence of psoriasis in our two patients is more than coincidence, and that noninfectious, inflammatory lesions of bone may be another musculoskeletal manifestation of psoriasis. This rare association, as well as the association of PPP with disorders associated with new bone formation, may shed new insights on the relatively common finding of periosteal elevation associated with psoriatic arthritis and the occasional severe juxta-articular osteolytic destructive bone lesions seen in psoriatic arthritis. 相似文献

New and modified recombinant factor IX (rFIX) products are in development and accurate potency estimation is important to ensure the consistency of production and efficacy of these therapeutics. Collaborative study data obtained during the replacement of the 3rd International Standard (IS) for FIX concentrate suggested that there was a discrepancy between potency estimates for rFIX using clotting and chromogenic methods, when the rFIX candidate was measured against the plasma‐derived FIX (pdFIX) IS. This study explores potential chromogenic and one‐stage clotting method discrepancies in more detail. Five batches each of rFIX and pdFIX were assayed against the 4th IS FIX concentrate (a pdFIX) by activated partial thromboplastin time (APTT) one‐stage clotting assay and specific functional chromogenic assay. The potency of rFIX by chromogenic assay was consistently around 70% of the one‐stage clotting potency (average 78 and 108 IU mL?1 respectively). These differences were not observed with pdFIX, which had similar potencies (average 96 IU mL?1) by each assay method. In addition, different APTT reagents yielded different potency estimates for rFIX when assayed against the pdFIX IS, with a variation of up to 23%. In all cases, the differences were largely resolved when a rFIX reference was used as the standard. This study highlights some of the challenges associated with assay of rFIX products in the laboratory and that careful consideration needs to be given to the choice of reference material used. This is especially important with the imminent arrival of new and modified rFIX products. 相似文献
