Traumatic tear of the rotator interval.

We studied 10 patients with capsular tear of the glenohumeral joint in the rotator interval -- the triangular space separating the supraspinatus and subscapular tendons. The patients, manual laborers and athletic people, had no previous shoulder pain. Tears appeared after forced internal rotation caused by trauma. The pain was anterior and radiated distally. Pain was absent at rest but recurred immediately after activity was resumed. On examination, range of motion was normal. Hawkins' impingement sign and the palm-up test usually caused pain. Radiographic findings were normal. Arthrography showed leakage of contrast medium into the subscapularis fossa. The tear was not visualized with ultrasonography or magnetic resonance imaging. Eight patients underwent an operation consisting of minimal acromioplasty with coracoacromial ligament resection, coracoidplasty, and suture of the rotator interval. All patients had relief of pain and return of full function.

Effectiveness and safety profile of leflunomide in rheumatoid arthritis: actual practice compared with clinical trials.

OBJECTIVE: Leflunomide, an immunosuppressant agent for treating rheumatoid arthritis, was first marketed in France in 2000. Three years after its launch, we sought to assess its prescription patterns in the real world of prescription and use, and to see if its efficacy and safety profiles observed during clinical trials were confirmed. METHODS: All patients treated with leflunomide from May 2000 to April 2003 in the Department of Rheumatology of the Bordeaux University Hospital were identified, and their treatment patterns and outcome ascertained. This was compared to data from clinical trials. RESULTS: 116 were included (mean age = 55 years, 70% women). Almost 21.7% stopped treatment for lack of efficacy (after a mean delay of 3.6 months), 16% for secondary loss of efficacy (median = 7 months), and 32% for the occurrence of an adverse event (half within 4 months). Over a similar time frame in clinical trials, in patients of about the same age and sex but with less severe disease, the corresponding figures were 7-17% for lack or loss of efficacy, and 14-22% for adverse effects. At one year of follow-up, the discontinuation rate was 70% in the cohort compared to 28-47% in clinical trials. DISCUSSION: The differences between the two populations confirm the need to conduct post-marketing studies in order to obtain better knowledge on the effectiveness and safety of a new drug. In many cases, a simple drug utilization study can provide relevant information on the degree of shift between populations included in clinical trials and those treated in real life.

[Results of a regional survey on the treatment of rhizomelic pseudopolyarthritis and temporal arteritis. Apropos of 242 cases treated by various modalities with synthetic antimalarials, corticoids and non-steroidal anti-inflammatory agents].

The authors report the results of a retrospective therapeutic survey concerning 176 cases of rhizomelic pseudopolyarthritis (RPP) and 66 cases of temporal arteritis (TA). Of 128 cases of RPP treated initially by synthetic anti-malarials (SAM) and non-steroidal anti-inflammatory agents (NSAI), 66 were followed up until cure which was obtained after a mean of 23 months and 3 subsequently received brief steroid therapy. 45 cases of RPP were treated initially with corticosteroids. They were generally associated with SAM which enabled early weaning of the steroids, towards the 8 th month, or at least reducing the dose. Cure was obtained within 24 months. Three patients were treated by NSAI and gold therapy. After cure, 5 cases of recurrence and 1 case of TA were observed. 40 cases of TA were initially treated with SAM and NSAI. Twenty cures were obtained within a mean of 28 months. 4 patients later received brief corticosteroid therapy because of an extension of the signs, including two cases of ocular manifestations with a resolving course. Of 25 cases of TA initially treated with steroids, 20 received SAM in combination, or in relay which enabled either steroids, weaning towards the 14th month or a reduction in the dose of steroids. Cure was obtained in an average of 35 months. One case of impaired visual acuity occurred during corticosteroid treatment. Immunosuppressants were used in one patient. No cases of recurrence were observed. Iatrogenic complications with SAM were rare, generally benign and reversible, in contrast to those associated with corticosteroid therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

[Multifocal tuberculous osteoarthritis and synovitis. 10 cases].

Synovial or osteo-articular tuberculosis is multifocal in about 10 percent of cases. Here, this form strikes older people and quite frequently the patients receive corticotherapy because of confusion with rheumatism. This premature treatment delays the diagnosis and at the same time favors the spreading of the germ. The 10 patients observed in this study had an average of 3 focuses simultaneously, the sites most often involved being the synovialis of the flexors of the fingers, the discovertebral articulations, the knee and the tibiotarsalis. The diagnosis is based on the presence of fistula (4 times out of 10), x-ray of the lungs (4 miliaries and 1 infiltrate), films of the spine (characteristic images of Pott, 6 times), the bacteriological study (recovery of Koch bacillus 3 times upon direct examination and 6 times after culture) and finally the biopsy of the synovialis (specific synovitis 3 times out of 4 biopsies). Antituberculosis treatment often involved tolerance problems. It helped to cure 7 patients with few sequelae on the whole. The 3 other patients died either because of old age or complications due to corticosteroids.

[Methotrexate and non-steroidal anti-inflammatory agent combination in rheumatoid arthritis].

It is well known that methotrexate (MTX), used at high dosage in cancer patients, must not be combined with a non-steroidal anti-inflammatory drug (NSAID) because of high risk of side effects; prescribed at low dosage (< or = 15 mg per week) in rheumatoid arthritis patients, MTX is often combined with an NSAID. Some cases reported in the literature underline the potential toxicity of the association of low dose MTX with an NSAID, but most of the pharmacological studies do not confirm this hypothesis. Except for salicylates, NSAIDs do not affect the absorption, distribution, protein binding, area under the curve, half-life, or the elimination of MTX. Therefore, if necessary, MTX (< or = 15 mg per week) can be combined with an NSAID during the treatment of rheumatoid arthritis.
