Clinical features of septic arthritis of sternoclavicular joint.

We studied 21 patients with septic arthritis of the sternoclavicular joint at Chulalongkorn University Hospital between January 1987 and January 1997. There were 15 males (71.4%) and 6 females (28.6%). The mean age was 47.4 years with a range of 16 to 69. More than half of the patients (57.1%) were aged more than 50 years and most had associated diseases including diabetes mellitus and cirrhosis. Almost all of the younger age group had a history of intravenous drug abuse. All of the patients had fever and sternoclavicular joint pain. Most of the patients (66.7%) had monoarticular arthritis, whereas, the others had oligoarticular arthritis. Staphylococcus aureus was the most commonly or identified organism in the patients. Retrosternal abscess was seen by computerized tomography in 6 patients (28.6%). All patients received parenteral antibiotics, and 5 patients (23.8%) required surgical drainage of a retrosternal abscess. Eighteen patients recovered but there were 3 (14.3%) deaths. All of these had retrosternal abscesses. The major cause of death was septic shock. Septic arthritis of the sternoclavicular joint is an uncommon disease in Thai clinical practice. Although uncommon, retrosternal abscess is a life threatening complication.

Initial disease modifying antirheumatic drugs and prednisolone prescriptions for patients with rheumatoid arthritis: a 15-year study.

OBJECTIVE: To compare patterns and time trends of initial disease-modifying antirheumatic drugs (DMARDs) and prednisolone prescriptions for patients with rheumatoid arthritis (RA) by the rheumatologists at King Chulalongkorn Memorial Hospital, Bangkok, Thailand over a 15-year period, as well as their side effects. METHOD: Medical records of all patients with RA seen at the Rheumatology Clinic from January 1983 to June 1997 with a duration of follow-up of 6 months or more were reviewed. Information on the disease, initial DMARDs prescriptions and their side effects, prednisolone use, dosage and side effect(s) were focused and compared among three 5-year periods (1983-1987, 1988-1992 and 1993-1997). RESULTS: 236 patients were included in this study. There were 44, 82 and 110 patients in the first, second and third period, respectively. Methotrexate (MTX) was the most frequently prescribed DMARD in all time periods. Dapsone and intramuscular (i.m.) gold were prescribed in the first period while antimalarial drugs and sulfasalazine (SSZ) were increasingly used in the second and third periods. Combination treatment of DMARDs was first used in the third period. Side effects from MTX were observed in patients with a longer duration of treatment (p < 0.05). Patients prescribed combined DMARDs did not develop more side effects compared with those who had monotherapy. Prednisolone was prescribed in 57.2 per cent of the patients, most being newly prescribed at the clinic. Mean starting dose of prednisolone was 8.9 mg per day. 64 patients took prednisolone together with non-steroidal antiinflammatory drugs (NSAIDs). Gastrointestinal side effects did not increase in these patients. CONCLUSION: MTX was the most frequently prescribed DMARDs regardless of the time period. Antimalarial drugs, SSZ and combination of DMARDs (most were MTX + chloroquine) have been prescribed more in the last 5 years, while dapsone, auranofin and i.m. gold were rarely used as initial DMARDs. Low dose prednisolone was prescribed in more than half of the patients with RA. Side effects from DMARDs and prednisolone found in this study were comparable to previous reports.

Streptococcal arthritis in Thai adults: case series and review.

The incidence, clinical spectrum, types of streptococci in Thai adults with streptococcal arthritis in Chulalongkorn Hospital are similar to Western reports. The most frequently found organism was group A Streptococcus and the second was group G. Most of the patients were elderly who usually had underlying medical and/or joint diseases. There were 3 patients with underlying lepromatous leprosy which has never been reported before, while mixed types of streptococcal infection in the same joint, mixed types of streptococcal infection in the same patient and a patient with group C lumbar spondylodiskitis were also found. The most reliable diagnostic test is synovial fluid culture. All streptococcal isolates in our review were sensitive to penicillin and the clinical responses correlated with antibiotic sensitivity tests. Intravenous antibiotics and adequate drainage are the treatment of choice. The duration of treatment ranged from 4 to 6 weeks and most patients responded well. The overall mortality rate depended on host factors, organism virulence and treatment administered.
