RESUMO
Over a 6-year period (1982 to 1988), 36 episodes of septic arthritis were diagnosed in 35 heroin addicts from Barcelona, Spain. Thirty (86%) were men and five (14%) were women, with a mean age of 24 years (range, 14 to 39). Twenty-nine episodes (80%) were monoarticular and seven (20%) were oligoarticular. The sacroiliac (16 cases), sternoclavicular (8), hip (5), and shoulder (4) joints were most frequently infected. Staphylococcus aureus and Pseudomonas aeruginosa were the etiological agents in 75% and 11% of episodes, respectively. Response to antibiotic treatment was good in 32 cases (90%), eight patients needed surgical drainage, and none died. We conclude that septic arthritis in heroin addicts localizes predominantly in axial joints. In our geographic area, infection with S aureus is more frequent than with gram-negative rods such as P aeruginosa or Serratia marcescens, which are most frequently found in reports from the United States.

We studied a case of long-standing chondrocalcinosis that after 40 years affected almost all fibrocartilages, hyaline cartilages, and articular cavities within the subject. Massive deposits of dihydrocalcium pyrophosphate (CPP) were also found in nonfissured nucleus pulposus of the vertebral disks. To our knowledge, this is the first report of CPP deposits in these disks.

The familial study of three patients from the Osona region (Barcelona) with early onset (fourth decade) of articular chondrocalcinosis (CCA) disclosed the occurrence of CCA in other members of the three families. The clinical and radiological features were heterogeneous, with polyarticular forms with marked clinical expression in one family, oligoarticular forms with few symptoms in another, and both types in the third family. These first reports of familial CCA in Catalonia can be added to those found in other parts of Spain, and they support the idea that familial cases of CCA are not exceptional if adequately investigated.

We report two cases of osteoarticular tuberculosis in heroin addict patients infected with human immunodeficiency virus. Both patients presented an inflammatory tumor in the anterior chest wall, with subacute onset; one patient had chondrosternal involvement and the other had chondrocostal involvement with a retrosternal pus collection. Diagnosis was established by needle aspiration of the tumor that gave raise to caseum. Ziehl-Neelsen stain was positive and Löwenstein-Jensen culture yielded Mycobacterium tuberculosis in both cases. The course was good after surgical debridement and tuberculous treatment for 6 months. We review the features of osteoarticular tuberculosis in drug addicts and patients infected with human immunodeficiency virus that in our environment mainly affects this population group. As in our geographical area, an increased incidence of both infections does exist and owing to the high prevalence of extrapulmonary and disseminated tuberculosis in those patients, it is expected that in a future time, the number of cases of tuberculosis will increase. Therefore, physicians must entertain a high degree of suspicion with the purpose of establishing an early diagnosis of these atypic presenting forms.

HLA antigens were studied in three different groups of 50 patients each. These included (a) Forestier's disease, (b) ankylosing spondylitis, and (c) polyarthrosis of the hands. HLA typing included 12 specificities from locus A and 15 from locus B, the frequencies being compared to those in 700 normal controls. No significant differences were found in the frequency of distribution between the polyarthrosis patients and the normal population. In patients with Forestier's disease, B5 was increased, but this was not a significant difference. The antigen B27 was present in 94 per cent of patients with ankylosing spondylitis, confirming previous studies.

OBJECTIVES: To undertake an epidemiological survey of the prevalence of radiological chondrocalcinosis in the elderly population of Osona, a rural area of Catalonia, north east Spain. METHODS: Knee and wrist radiographs were performed on 261 subjects (141 women, 120 men) aged at least 60 years, who attended a series of 35 general practitioners for various medical problems. RESULTS: Twenty seven subjects had articular chondrocalcinosis, which represents a crude prevalence of 10%. Articular chondrocalcinosis was more often observed in women than in men (14 v 6%). Articular chondrocalcinosis increases in occurrence with age, rising from 7% in subjects aged 60-69 years to 43% in subjects older than 80 years. A similar occurrence of articular chondrocalcinosis was noted in the indigenous population, in which several cases of familial chondrocalcinosis have previously been reported, and in subjects born in other areas of Spain. All but one subject with articular chondrocalcinosis had chondrocalcinosis of the knee. The occurrence of rheumatic disorders did not differ significantly between subjects with articular chondrocalcinosis and those without. CONCLUSIONS: Articular chondrocalcinosis is an age related disorder, which could partly explain the discrepancies in its prevalence reported in previous studies. In most subjects with articular chondrocalcinosis recruited from an unselected population the clinical manifestations are probably mild or even absent.

The value of determining D-lactate concentrations in body fluids for the rapid diagnosis of bacterial infections was investigated. A total of 336 body fluid samples were analyzed: 208 ascitic fluids, 57 synovial fluids, 40 cerebrospinal fluids and 32 pleural fluids. Using a cut-off value of 0.05 mM, the overall sensitivity was 0.96 and the specificity was 0.88. Therefore, the measurement of D-lactate concentration in body fluids offers a rapid (2-hour) and useful method of differentiating between infectious and non-infectious body fluid diseases.

The prevalence, type, and factors that may influence the development of bone disease in primary biliary cirrhosis, have been investigated in 20 consecutive patients, who, in addition to liver function tests and mineral and vitamin D metabolism studies, were submitted to a transiliac bone biopsy after tetracycline double-labeling for quantitative histomorphometric examination. Intestinal calcium absorption was also assessed in 16 patients. Seven patients (35%) had reduced bone volume and were considered osteoporotic. Three also had bone mineralization impairment, but did not have criteria for osteomalacia. Bone formation was depressed in 15 patients, and bone resorption was low or normal in 19 cases. Eroded surfaces were reduced in all osteoporotic patients. Duration of primary biliary cirrhosis was significantly longer in patients with osteoporosis (6.3 +/- 0.6 yr) than in those without osteoporosis (2.6 +/- 0.6, p = 0.004). Moreover, osteoporosis was more prevalent in postmenopausal women, and in those who had intestinal calcium malabsorption, which was present in 80% of osteoporotic patients but in only 18% of nonosteoporotic patients (p = 0.03). Osteoporosis and mineralization bone impairment were unrelated to the severity of cholestasis. 25-Hydroxyvitamin D was significantly lower in those patients with intestinal calcium malabsorption. The results of this study indicate that osteodystrophy in primary biliary cirrhosis is characterized mainly by "low-turnover" osteoporosis, which is related to the duration of the liver disease, postmenopausal condition, and calcium malabsorption.

We studied the clinical, scintigraphic, and histopathologic characteristics of 26 intravenous drug abusers with costochondral involvement secondary to systemic infection with Candida albicans. The clinical findings were of a mass appearing in the anterior region of the thorax. In general, signs of inflammation were absent. Histopathologic study of this costochondral mass in 12 patients showed perichondritis in 100% and myositis in 87%, with secondary involvement of cartilage in 43% and of bone in 75%. Results of bone scintigrams using 99mTc-methylene diphosphonate were positive in only 7 of 15 patients (47%), with a correlation between positive uptake and osteitis. Gallium scintigraphy findings were positive in 9 of 10 patients (90%). The greater sensitivity of 67Ga was probably because the invariably present pericartilaginous inflammatory mass was not always accompanied by secondary cartilage and bone involvement.

Sacral insufficiency fractures have been related to osteoporosis and steroid therapy, however only one case has been reported following liver transplantation. We describe three patients who developed insufficiency fractures of the sacrum following liver transplantation, these fractures could be overlooked or confused with inflammatory processes involving the sacrum.

Fifty one patients with ankylosing spondylitis (AS) were typed for HLA-A, B, C, DR, and DQ antigens. The antigen frequencies were compared with those of a normal population and with a B27 positive control group. All but one of the patients with AS were HLA-B27 positive. A positive linkage disequilibrium between Cw1, Cw2, DR1, and the B27 antigen was observed. Patients with AS showed a significant increase in DQw2 antigen compared with the B27 positive control group. No differences in antigenic frequencies were observed in patients having peripheral arthritis and patients with only axial involvement. Seven out of nine patients (78%) with an erosive peripheral arthritis were DR7 positive, suggesting that DR7 or genes closely linked could be related with a more aggressive peripheral joint involvement in patients with AS.

OBJECTIVES: Chronic lower-back pain (CLP) is a common pathology and has a high social and economic impact, especially in primary care where its treatment is changing at present. The results of the multi-disciplinary assessment of 100 patients with chronic lower-back pain are given. DESIGN: Cross-sectional, observational and prospective study. SETTING: Out-patient clinics of the rheumatology service of a tertiary-level hospital (referral from base districts where there is no primary care rheumatologist). PATIENTS: 100 consecutive patients seen for back pain lasting for more than 6 months were analysed. INTERVENTIONS: There was no therapeutic intervention. MEASUREMENTS AND MAIN RESULTS: The personal, work, clinical, examination, x-ray, functional and psychological features of 100 patients with CLP were analysed. There were 38 men and 62 women, with average age of 45 +/- 10 years and low social, cultural and job levels. Pain had lasted 82 +/- 7 months and 52% had had time off work. Mean intensity of pain was 6.5 +/- 2.3 (scale of zero to 10). There was vertebral restriction in 16%, and conduct expressing pain on examination in 47%. The x-ray showed disorder in 51%. Functional incapacity was nil or light in 46% and severe in 16%. 74.5% of the patients were depressed; 57% had features of anxiety; and 44% were anxious at the time of the interview. CONCLUSIONS: Patients with CLP are middle-aged, with long-standing pain and frequent time off work. Pain intensity is high, but vertebral restriction, disorders on x-rays and functional incapacity are scant. However, anxiety and depression levels are high. This could suggest a change in how we treat CLP towards a multi-disciplinary approach and psycho-affective, social and labour assessment, both at the time of assessment and in later treatment of patients.

Cutaneous immunofluorescence studies were carried out in 21 patients with ankylosing spondylitis (AS) and the results compared with those for 18 healthy subjects. The most prominent finding was the presence of IgA in dermal vessels of patients with AS (71% compared with 17% of the control group). IgG and IgM cutaneous deposits were also observed in patients with AS, but these results did not differ from those of the control group. A renal biopsy was performed in three of the patients presenting with unexplained microscopic haematuria. One of them had an IgA nephropathy, but no correlation was found between kidney and skin deposits of IgA. These findings suggest that IgA cutaneous deposits in AS are not a marker of IgA nephropathy but stress the role of immunoglobulin A in the pathogenesis of this disease.
