    Description / Table of Contents: Résumé Des cultures de monocouches cellulaires d'épiphyses fémorales distales d'embryons de veaux sont étudiées immédiatement après la première sub-culture, réalisée après culture primaire. L'examen au microscope optique classique montre des dépôts disséminés de matériel métachromatique: en microscopie électronique, de fines fibrilles, considérées comme des fibres de collagène, en voie de développement, ont été observées. La nature des sécrétions cellulaires a été étudiée à l'aide de précurseurs radioactifs, fractionnés sur Sephadex G200, ainsi qu'à l'aide de chromatographie par échange d'ions. La digestion enzymatique par hyaluronidase et chondroitinase AC et ABC, bactérienne et testiculaire, démontre que les cellules synthétisent 70% de glycosaminoglycanes sulfatés et 30% de glycosaminoglycanes non sulfatés. Parmi les glycosaminoglycanes, 70% sont constitués par du chondroitine-4-sulfate, 20% par du chondroitine-6-sulfate et le reste probablement par du keratane-sulfate. Les études avec des acides aminés marqués indiquent que les cellules synthétisent une protéine de poids moléculaire élevé, contenant de l'hydroxyleproline, ainsi qu'une protéine non-collagénique, mise en évidence par incorporation de tryptophane.
    Abstract: Zusammenfassung Einschichtige Zellkulturen von der distalen Femurepiphyse von Kalbsembryonen wurden nach der ersten Subkultur untersucht, welche nach der Verschmelzung der primären Kulturen angesetzt wurde. Die lichtmikroskopische Untersuchung zeigte verstreute Ablagerungen von metachromatisch gefärbtem Material; bei der Elektronenmikroskopie wurden feine Fibrillen festgestellt, welche als Collagenvorstufe angesehen wurden. Nach einer Kultur von mehreren Tagen zeigte sich eine lacunäre Anordnung der Zellen. Die Beschaffenheit der Zellsekretionen wurde mittels radioaktiv markierten Verbindungen untersucht, welche auf Sephadex G200 und durch Ionenaustausch-Chromatographie fraktioniert wurden. Die enzymatische Verdauung mit bakterieller und testikulärer Hyaluronidase und Chondroitinase-AC und-ABC zeigte, daß die Zellen 70% sulfatierte und 30% nichtsulfatierte Glycosaminoglycane synthetisierten. Die sulfatierten Glycosaminoglycane enthielten 70% Chondroitin-4-Sulfat, 20% Chondroitin-6-Sulfat, und der Rest war wahrscheinlich Keratansulfat. Untersuchungen mit markierten Aminosäuren-Vorläufern deuteten darauf hin, daß die Zellen ein Hydroxyprolinhaltiges, hochmolekuläres Protein synthetisierten und dazu etwas Eiweiß, bei dem es sich auf Grund des Tryptophaneinbaues nicht um Collagen handeln kann.
    Notes: Abstract Monolayer cell cultures from the distal femoral epiphyses of embryo calves were studied following the first subculture, which was carried out after confluence in primary culture. Light microscopic examination revealed scattered deposits of metachromatic-staining material; on electron microscopy fine fibrils considered to be developmental collagen were seen. After several days in culture lacuna-like patterns of cells were seen. The nature of the cell secretions were studied by radioactive precursors, which were fractionated on Sephadex G200 and by ion exchange chromatography. Enzyme digestion with bacterial and testicular hyaluronidase and chondroitinase-AC and-ABC revealed that the cells synthesized 70% sulphated, and 30% non-sulphated glycosaminoglycans. Of the sulphated glycosaminoglycans 70% was chondroitin-4-sulphate, 20% chondroitin-6-sulphate, and the remainder probably keratansulphate. Studies were labelled amino acid precursors suggested that the cells synthesized a high-molecular weight protein containing hydroxyproline, as well as some non-collagenous protein, shown by tryptophan incorporation

    Notes: Summary Many difficulties were encountered in a population survey of rheumatic complaints in a remote village area in the Philippines affecting the reliability of estimates of population prevalence. In phase I, a simple questionnaire identified 269 adults out of 950 who had rheumatic symptoms. In Phase II, 234 or 87% of positive respondents were requestioned using a more detailed pro forma. There were 196 with peripheral joint pain, 67 with neck pain and 137 with back pain. One third attributed their symptoms to work and 127 subjects had to stop work because of their complaints. Disability, including an inability to carry loads, affected nearly 1.8% of the population. Questions designed to detect rheumatoid arthritis and gout were not satisfactorily answered. Of those with complaints, 82% indicated that they still required help for their symptoms. In phase III, 166 subjects were medically examined. Osteoarthritis of the knee was found in 25 and 17 had Heberden's nodes. There were 16 with epicondylitis; 16 had rotator cuff pain and 35 had levator scapulae insertion pain. Three of these and three others had neck or shoulder swellings related to carrying loads on poles. Definite rheumatoid arthritis was diagnosed in two subjects and gout in five. No case of ankylosing spondylitis was identified. Thus, rheumatic complaints were common in this rural, community and were frequently severe enough to cause disability and loss of time from work. Health worker education is required on how to handle these problems.

    Notes: Summary During a community survery of rheumatic complaints in a Javanese rural population, fibrous shoulder girdle nodules having a consistent form and position were observed in seven men. This was 2.3% of 303 men with complaints examined from a total population of 2184 men surveyed by house-to-house interviews (response rate 95.2%). Nodules were not seen in any of the 640 women examined with complaints from a total population of 2499, nor were they seen in 130 men and 159 women with complaints from an urban population of 481 men and 590 women over the age of 15 years. It was considered most likely that these shoulder nodules were the result of longstanding repetitive mechanical irritation due to carrying heavy loads by a resiliant wooden pole balanced across the shoulder.

    Notes: Summary As part of the WHO/International League Against Rheumatism (ILAR) sponsored community organized programme for the control of rheumatic disease (COPCORD), an arthritis community education programme (ACE) was undertaken utilizing the traditional form of entertainment in a rural area in Central Java-the wayang. The point prevalence rate of musculoskeletal complaints was estimated in 4683 men & women aged 15 years and over by house-to-house interviews. From 1105 respondents recording recent musculoskeletal pain, 844 were randomly selected and half the latter attended a puppet shadow play (wayang) incorporating the ACE. The other half, matched for age, sex and educational level who did not see the play, served as controls. A questionnaire containing biphasic choices of correct or incorrect ways of performing activities of daily living (ADL) to minimize musculoskeletal problems was administered to the whole group before, 1 month and 6 months after the wayang. Increased knowledge of correct ways of performing ADL (correct ADL) in the intervention group compared with the control group at 1 and 6 months after wayang was significant (P〈0.05). Comprehension of correct ADL following the wayang could be demonstrated even in subjects who were illiterate and those who had attended primary school only. Retention of knowledge at the 6 month assessment declined more markedly in the illiterate group. ACE by wayang was shown to be feasible and effective in transferring knowledge on ADL to people with musculoskeletal problems in the sample population in Java. This effect could be shown even in the poorly educated section of the community. In the absence of adequate numbers of skilled primary health care professionals, public education programmes utilizing traditional forms of entertainment should be considered, especially in rural communities in developing countries.

    Notes: Summary During inflammation the rheumatoid synovial membrane is invaded by a number of different cell types. When activated most of these cells produce cytokines including tumor necrosis factor alpha (TNFα) and interleukin-1 beta (IL-1 β). These cytoiines are believed to stimulate production of degradative enzymes and disturb the equilibrium between such enzymes and their inhibitors resulting in tissue damage. In this study we investigated the localisation of TNFα and IL-1 β at the cartilage-pannus junction (CPJ). Here, cytokines are well placed to influence the integrity of articular cartilage. Tissue was derived from advanced rheumatoid (RA) and, as a comparison, osteoarthritic (OA) joints at the time of replacement surgery (arthroplasty). Antibody staining of fixed serial sections of tissue localised cells that were associated with IL-1 β and TNFα. Cell markers for macrophages and endothelial cells were included to provide positive identification of the cytokine-associated cells. Analysis of these sections revealed that both TNFα and IL-1 β were associated with macrophages, particularly those in the synovium overlying cartilage (pannus) and endothelial cells. Positive staining was seen at the CPJ in RA and in similarly located tissue in OA. The similar distribution of cytokines in OA was unexpected even if the overall numbers of tissue and infiltrating cells in the CPJ were different in the two diseases. This highlights the possible role played by endogenous inhibitors [1, 2] in influencing the degree of cytokine activity necessary to explain the different pathogenic mechanisms in RA and OA.

    Notes: Abstract As the available in vitro and in vivo data suggest that interleukin (IL)-4 and IL-10 have immunosuppressive activity, our hypothesis was that serum IL-4 and IL-10 levels would correlate inversely with parameters of inflammation in patients with inflammatory arthritis. IL-4 was detected in the serum of 12 out of 140 patients with rheumatoid arthritis (RA), which was increased compared to the proportion found with patients with osteoarthritis (OA; P〈 0.02). In addition, IL-4 was detected in the serum of 2 of 19 patients with systemic lupus erythematosus (SLE), 2 of 24 patients with psoriatic arthritis and 1 of 5 patients with Behçet's syndrome. No IL-4 was detected in patients with the following conditions: OA (58 patients), gout (17 patients), ankylosing spondylitis (6 patients), Reiter's syndrome (6 patients), polymyalgia rheumatica (6 patients), temporal arteritis (5 patients) and scleroderma (3 patients). No IL-10 was detected in any of the sera tested. We discuss the possible relevance of these results to the regulation of the immune response evident in inflammatory arthritis.

    Notes: Summary A statistically significant association of clinical rheumatoid vasculitis (excluding nodules or nail-fold infarcts only) with the HLA B8 DR3 phenotype was found when comparing 30 patients with vasculitis with 84 classic or definite rheumatoid patients without clinical vasculitis. The previously reported association on HLA DR4 with rheumatoid disease was also confirmed.

    Notes: Summary In initiating a community oriented programme for the control of rheumatic disease (COPCORD), 1685 people of all ages from a rural area in the Philippines were questioned by primary health care workers (PHW) for limb and spinal rheumatic pain and disability. The total complaint rate was 15.3% for men and 18.5% for women. For those 15 years and older the age adjusted rheumatic pain rates for pain present at the time of survey were 28.4% for the Philippines and 22.6% for Lawrence's UK population. The most common rheumatic pain sites in this community were knee, lumbar spine, neck and the trapezius muscle. The disability rate was 4.5% for those 15 years and older. One quarter of those with pain had received medical attention and the remainder, herbal treatment, massage, various faith and/or self-treatment methods.

    Notes: Summary In the cartilage-pannus junction of 14 patients with rheumatoid arthritis (RA) and seven patients with osteoarthritis (OA), monoclonal antibodies to keratan sulphate (KS) and chondroitin sulphate (CS) stained a transitional fibroblastic zone (TFZ) within the pannus in nine RA patients and one OA patient. In three patients this was clearly localised to the cytoplasm of cells in this zone, but in all remaining cases KS and CS could be demonstrated in the surrounding matrix. This area was distinguished from adjacent pannus which contained many blood vessels and cells positive for MHC Class II antigen. Specific markers for glycosaminoglycans have been employed to demonstrate that chondrocyte-derived cells and matrix contribute to the changes seen at the cartilage-pannus junction in RA-affected joints.

    Notes: Abstract The prevalence of various forms of soft tissue rheumatism, including painful low back syndrome (PLBS), painful restricted shoulder syndrome (PRSS), and epicondylitis without an underlying specific rheumatic disease, and the resultant loss of time from work were determined in a total population of 4,683 rural and 1,103 urban subjects aged 15 years and over in Central Java, Indonesia. In the rural study, 763 respondents with, and 355 respondents without complaints were examined. The urban survey evaluated 925 subjects. Prevalence rates in the rural and urban subjects were 20.0% and 25.8%, respectively, for PLBS, 14.5% and 16.2%, respectively, for PRSS, and 5.8% and 7.5%, respectively, for epicondylitis. Lost time from work in the rural and urban subjects was 9% and 2.2%, respectively, for PLBS, 5% and 1.1%, respectively for PRSS, and 2% and 1.3%, respectively for epicondylitis. The mean number of lost work days per year in the rural and urban subjects were 15.3 and 21.1, respectively, for PLBS, 8.1 and 15.2, respectively, for PRSS, and 3.9 and 2.3, respectively for epicondylitis. Thus, these forms of soft tissue rheumatism exerted significant effects on community life, apart from causing pain and discomfort. Work days lost directly means diminished income in populations lacking any form of unemployment benefits.
