Flexor tendon synovitis caused by Mycobacterium terrae resulted in considerable permanent functional impairment of the hand in six patients. Initial symptoms were subtle and uncharacteristic. Cortisone injections aggravated the condition. Surgical treatment including synovectomy was combined with antimycobacterial chemotherapy. Early diagnosis obtained by culture of synovial biopsy material to detect mycobacteria may result in an improved outcome in chronic synovitis.
A case of gonococcal polyarthritis in a 19-year old woman was rheumatoid factor positive on presentation. Titres of rheumatoid factor declined to normal as her arthritis resolved with treatment. A positive rheumatoid factor test in a person with possible gonococcal polyarthritis should therefore be disregarded until an infective aetiology has been ruled out.
Thirty-nine patients with rheumatoid arthritis who had presented with tarsitis before, were investigated at the level of the rearfoot. The first 17 patients had CT with previous tenography when it was possible; the following 22 patients had MRI with gadolinium injection. Tendon involvement appeared in 52.9% of the cases on CT, and in 90% of the feet on MRI; therefore, in case of clinical or radiological signs of tarsitis, it appears that tendon involvement must be suspected. With the two procedures the tibialis posterior tendon lesions were very predominant. In the majority of the patients (31/39), there was associated involvement of two or more tendons. If there is a ruptured tendon, the authors think that one must be cautious with surgical tendinous transfer; indeed, the long-term results of this surgical procedure present a strong probability of being compromised in rheumatoid arthritis which is a progressive disease.

We compared the efficacy of conservative management of de Quervain's disease in 30 women postpartum (group 1) and 30 nonpregnant women (group 2). All patients underwent conservative management consisting of 2 weeks of splinting of the affected wrist, followed by physiotherapy and antiinflammatory drugs (NSAIDs). Clinical evaluation was performed using a functional score and the visual analogue scale (VAS) of Scott-Huskinson at entry to the study, 1 month later, and at a follow-up of 6 months. Conservative management gave good results in patients in group 1. At the 6-month follow-up a significant difference between the two groups on pain and function was evident. Only one patient in group 1 versus 25 patients in group 2 underwent surgery because of failure of conservative management.

We report the case of a 34-year-old man with a rheumatoid pulmonary nodule preceding the development of articular symptoms of rheumatoid arthritis. Pulmonary nodules are a well known feature of rheumatoid arthritis and are mostly seen in severe established rheumatoid factor-positive cases. To differentiate between benign and malign pulmonary nodules we discuss the use of positron emission tomography (PET). Despite intensive therapy with steroids and methotrexate in our patient, within months he developed a severe tibialis posterior tendinitis, with partial rupture and evolution to a planovalgus deformity requiring surgery. Both these symptoms are rare but demonstrate the need for close follow-up in early rheumatoid arthritis.
Mycobacterium szulgai, a scotochromogenic mycobacterium, is a newly recognized pathogen of man and has been reported to cause pulmonary infections, olecranon bursitis and cervical adenitis. We isolated M. szulfai from granulomatous tissue removed at surgery from a young florist with the carpal tunnel syndrome. The organism was susceptible to ethambutol and rifampin but resistant to isoniazid. Cure was achieved by debridement and chemotherapy with ethambutol and rifampin. Neither the source in our patient nor the natural habitat of M. szulgai is known. Because it resembles M. gordonae and M. flavescens, common scotochromogenic mycobacteria in tapwater, care must be taken to avoid dismissing M. szulgai as a contaminant when it is isolated from tissue.
