In general, hallux rigidus arthrosis is said to occur in patients suffering from gout more frequently than average, and it should be valued as a symptom of chronic gout. But as a reevaluation of this problem shows, no criteria can be stated as to causal relationship between hyperuricemia (or gout) and hallux rigidus arthrosis. Obesity has to be considered a connecting link between both of them, and it is accelerating their genesis. Hallux rigidus arthrosis represents, like the arthrosis of Heberden the most frequent possibility for confusing it with gout.

Chondrocalcinosis is an arthropathy caused by deposits of calcium pyrophosphate-dihydrate microcrystals (CPPD) in the joints and occasionally in the tendons and ligaments. In our region it is almost always seen in its sporadic form in elderly subjects. The patients can be without symptoms or present four different clinical entities: an acute arthritis which can resemble and even be mistaken for an attack of gout or a septic arthritis; an inflammatory polyarthritis suggesting a rheumatoid arthritis; most frequently it appears as a benign polyarthrosis; sometimes it runs a destructive course capable of seriously damaging one or several joints. In certain cases chondrocalcinosis is associated with another metabolic disease. Familial forms have been described in some countries. Factors which induce the formation of the deposits of CPPD in the articular cartilages, fibrocartilages, the synovium and occasionally in the tendons and ligaments remain obscure. In contrast to urate gout, chondrocalcinosis appears to be due to a disturbance of pyrophosphate metabolism localized almost exclusively in the articular region. Its association with polyarthrosis rather frequently leads to destructive arthropathies. No etiological treatment for chondrocalcinosis exists at the present time. Therapy is limited to the administration of nonsteroidal antiinflammatory drugs and physiotherapy.

70 patients affected by methabolic joint diseases are reviewed. Xeroradiography has been performed in hand, foot and knee for studying soft tissue and bone lesions in 12 subjects affected by chronic gout and 5 by CPPD. Results show that xeroradiography is more effective than X-ray films in outlining soft tissue masses, especially little dystrophic meniscal calcifications, and initial lesions in bone.

329 synovial fluids from various joint diseases were examined. 95% of the fluids from arthrosis contained less than 1 000 cells/ml, figure which seemed to us to be the limit which separates arthrosis from arthritis. Above 100.000 cells/ml, the diagnosis is always pyogenic arthritis. Between 50.000 and 100.000 cells/ml, one may find pyogenic arthritis but also a few cases of rheumatoid arthritis, psoriatic rheumatism, gout and pseudo-gout. In chondrocalcinosis, the fluid variable, often poor in cells. The percentage of polymorphs is of little diagnostic interest; it exceeds 50% in all cases of pyogenic arthritis. R.A. cells are almost constant in fluids with more than 1 000 cells/ml and their diagnostic interest is not great.

The following assertion - continuously being alleged - is examined: Hallux rigidus arthrosis is said to occur in patients suffering from gout more frequently than average, and it should be valued as a symptom of chronic gout. Results of our own findings are as follows: 1. Hallux rigidus arthrosis becomes manifest in general on the right side or bilaterally, respectively; on the left side, however, it occurs rarely in an isolated state. 2. In patients with hallux rigidus arthrosis hyperuricaemia, gout, and obesity are seen more frequently than in adults of the normal population - these three diseases often are combined with static mutations in the region of the lower extremities. 3. No criteria can be stated as to causal relationship between hyperuricaemia (or gout) and hallux rigidus arthrosis. Obesity has to be considered a connecting link between both of them, and it is accelerating their genesis. 4. Hallux rigidus arthrosis represents - same as the arthrosis of Heberden - the more frequent possibility for confusing it with gout.

Because of degenerative joint diseases and the reduced resistance in older patients the correct diagnoses of joint-empyema is difficult. In 29 pat (> 60 y) the mean delay of diagnoses was 5.1 months. First location of the infection have been: urinary tract 12, pneumonia 6, skin infection 10, and decubitus 3. Risk factors have been diabetes 4, polyarthritis 3, gout 3 and tuberculosis 3. The species were: s. aureus 12, s. albus 2, streptococcus 2, diphtheroid 2, e.coli 2, pseudomonas 2, proteus 4, enterobacter 3 and salmonella 1. 8 patients demonstrated mixed infections. The high mortality (3 pat.) and the frequent general sepsis (5 pat.) underline the importance of a missed joint-empyema in the elderly.

There have been few epidemiological studies of bone and joint diseases in black Africa. Available data were generated by hospital studies which were inevitably flawed by selection bias. They found that the incidence and/or severity of rheumatoid arthritis were reduced in West Africa but not in urban areas of Southern and East Africa, as compared with industrialized countries. Ankylosing spondylitis was infrequent. The human immunodeficiency virus epidemic can be expected to increase the prevalence of spondyloarthropathies despite the fact that few black Africans are HLA B27-positive. Gout was the most common inflammatory joint disease seen in inpatients in West Africa and Equatorial Africa. Osteoarthritis of the fingers or hip and dysplasia of the hip were infrequent. The main causes of hip symptoms were sickle cell anemia and hemoglobin C disease whose manifestations include bone necrosis, osteomyelitis, and attacks of bone and joint pain. Osteoarthritis of the knee was common in West and Southern Africa, especially in obese women. Low back pain and sciatica due to disc herniation were as common as in Europe. Lumbar canal stenosis appeared more common in West Africa than in Southern Africa, with a predominance in females. Postmenopausal osteoporosis was exceedingly rare. Infectious diseases were prevalent as a result of underindustrialization and defective hygiene. The paucity of rheumatologists, young mean age of the population, and scarcity of population-based studies are sources of bias which should be taken into account when interpreting the available data on rheumatological diseases in black Africa. In the future, more rigorous studies made possible by increased access to health care will provide improved insight into the semiology and epidemiology of bone and joint diseases in this area.

Cytokines are important protein mediators in inflammatory joint diseases. The synovial fluid and plasma concentrations of interleukin-1 alpha (IL-1 alpha), interleukin-2 (IL-2), tumour necrosis factor-alpha (TNF-alpha), interferon-alpha (IF-alpha) and interferon-gamma (IF-gamma) were measured by RIA and ELISA in 28 rheumatoid arthritis (RA) patients (5 males and 23 females). Ten patients with knee effusions due to other causes (osteoarthritis, psoriasis, gout, rheumatic fever, systemic lupus erythematosus) were also studied. Eight of the RA patients had erosive disease. The synovial fluid IL-1 alpha and IL-2 concentrations were higher in Group 1 (erosive) [IL-1 alpha: 524 pg/ml (SEM: 127), IL-2: 3.28 ng/ml (SEM: 1.0)] than in either Group 2 (non-erosive) [IL-1 alpha: 241 pg/ml (SEM: 24), IL-2: 1.93 ng/ml (SEM: 0.6)] or Group 3 (non-RA) [IL-1 alpha: 267 pg/ml (SEM: 58), IL-2: 0.35 ng/ml (SEM: 0.6)] (p < 0.003 and p < 0.06 respectively). Plasma IL-1 and IL-2 levels were higher in Group 1 [IL-1 alpha: 408 pg/ml (SEM: 107), IL-2: 4.20 ng/ml (SEM: 1.5)] than in Group 2 [IL-1 alpha 150 pg/ml (SEM: 15), IL-2: 2.58 ng/ml (SEM: 0.7)] or Group 3 [IL-1 alpha: 140 pg/ml (SEM: 11), IL-2: 1.93 ng/ml (SEM: 0.3)] (p < 0.01, p < 0.009 respectively). There were no differences in the IFN-alpha, IFN-gamma or TNF-alpha levels between groups. These findings suggest that plasma cytokines levels may reflect synovial levels and that IL-1 alpha may play a significant role in erosive joint disease.

Articular chondrocalcinosis is identified by radiological opacity of articular cartilage and fibrocartilage with calcium intensity. This disease is often asymptomatic. The most significant clinical pattern is an acute arthritis, caused by microcrystals of calcium pyrophosphate dihydrate, the so-called pseudo-gout syndrome. Chronic pyrophosphate arthropathy can blend mechanical illness and inflammatory flares. When the X-rays are normal or display ordinary osteoarthritis, arthrocentesis makes the diagnosis thanks to the identification of calcium pyrophosphate crystals by polarizing microscope. Large joints are usually involved but the disease can impair the spine, small joints, tendon sheaths or synovial bursae. Though unpredictable the evolution can be worse than that of common osteoarthritis and strike joints that are usually spared by primary arthrosis. One can even see articular destruction. Thus certain patients may resemble rheumatoid arthritis, others a Charcot joint. The disease does not exist in children. Its outcome before the age of fifty implies the search for familial occurrence or a secondary form (hyperparathyroidism, hypophosphatasia, hemochromatosis, hypomagnesemia). The sporadic, primary chondrocalcinosis is very frequent in old age.

A 30-year-old Mexican woman had rash, deep ulcerations of her lower extremities, and debilitating polyarthritis. Her disorder simulated rheumatoid vasculitis, but serum rheumatoid factor was absent. The diagnosis of gout was confirmed by uric acid crystals in joint fluid and skin biopsy specimens and by x-ray crystallography. The age and sex were unusual for a patient with gout, and she had none of the commonly associated metabolic defects. This unique presentation for urate arthropathy needs further study.
