Septic bursitis

Intractable malleolar bursitis treated with lateral calcaneal artery adipofascial flap

Infections of the malleolar bursa, which is an adventitious bursa, rarely progress to intractable infectious bursitis. We present two cases of intractable malleolar bursitis. We performed successful transplantation of the lateral calcaneal artery adipofascial flap that resulted in healing of the bursitis. We discuss classification of bursae, treatments for bursitis and characteristics of the lateral calcaneal artery adipofascial flap.

Soft tissue disease

In the assessment of patients with soft tissue complaints, it is important to consider infectious etiologies in the differential diagnosis, especially in immunocompromised hosts. The exact categorization of some bacterial infections of the soft tissues may be difficult. The structures potentially involved include the skin, subcutaneous tissue, fascia, and skeletal muscle. Classification is usually based upon the anatomic structure involved, the infecting organism, and the clinical picture. The categorization is complicated by the fact that some infections may involve several soft tissue components and multiple bacterial species. In this review, we will cover cutaneous and subcutaneous tissue infections, fasciitis, septic bursitis, tendonitis, and pyomyositis.

Importance of focus identification in the treatment of Staphylococcus aureus bacteraemia

Staphylococcus aureus bacteraemia increases in frequency, and it is still a life-threatening disease. In recent years, some interesting studies such as the need for focus identification and the focus eradication have been performed. The aim of this review is to present an up-to-date assessment of the current challenges in the management of S. aureus bacteraemia in order to improve the outcome.

Pediatric septic bursitis: case report of retrocalcaneal infection and review of the literature

Septic bursitis in children is rarely discussed in the medical literature. This review summarizes the clinical manifestations and management of 10 cases of septic bursitis involving patients aged <16 years. In every case in this series, acute trauma was the predisposing condition. Group A streptococci were frequently isolated from the infected bursa. Septic bursitis, an underappreciated infection in children, should be considered in the differential diagnosis of common childhood conditions.

Management of acute bursitis: outcome study of a structured approach

In patients with septic bursitis the indications for admission and surgical intervention remain unclear, and practice has varied widely. The effectiveness of a conservative outpatient based approach was assessed by an outcome study in a prospective case series. Consecutive patients attending an emergency department with acute swelling of the olecranon or prepatellar bursa were managed according to a structured approach, subjective and objective outcomes being assessed after two to three days, and subsequently as required until clinical discharge. Long-term outcomes were assessed by telephone follow-up for up to eighteen months. 47 patients were included in the study: 22 had septic bursitis, 15 of the olecranon bursa and 7 of the prepatellar bursa. The mean visual analogue pain scores of those with septic bursitis improved from 4.8 at presentation to 1.7 at first follow-up for olecranon bursitis, and from 3.8 to 2.7 for prepatellar bursitis. Symptoms improved more slowly for patients with non-septic bursitis. No patients were admitted initially, but 2 were admitted (two days each) after the first follow-up appointment. One patient had incision and drainage on the third attendance, and 3 patients developed discharging sinuses, which all healed spontaneously. All patients made a good long-term symptomatic recovery and all could lean on the elbow or kneel by the end of the follow-up period. The management protocol, with specific criteria for admission and surgical intervention, thus produced good results with little need for operation or admission.

Musculoskeletal infections in patients with human immunodeficiency virus infection

Musculoskeletal infections constitute an unusual clinical manifestation in patients with human immunodeficiency virus (HIV) infection. Available information about patients' characteristics and their clinical course has been obtained mainly from case reports and small retrospective studies. Our retrospective study is the largest in the literature providing detailed information about the clinical and laboratory characteristics of HIV-infected patients with different musculoskeletal infections. We identified 30 patients with various infections of the musculoskeletal system during a 5-year period among a cohort of 3,000-4,000 HIV-infected patients, and we describe them along with all cases of musculoskeletal infections in patients with HIV reported in the literature since 1985. Septic arthritis was the most commonly reported infection of the musculoskeletal system. It usually affects young men with a median CD4 count of 241. The exact contribution of a previous history of intravenous drug abuse in the pathogenesis of septic arthritis is unclear from the present and previous studies. Staphylococcus aureus was the most commonly isolated agent (31.3%). Numerous atypical pathogens were also identified as causes of septic arthritis. Approximately 90% of patients recovered with appropriate antibiotic treatment. Osteomyelitis was a more serious infection which also affected young individuals but with lower CD4 counts (median, 41). Half the cases were due to atypical mycobacteria. The mortality rate in the previously reported cases and in our series was high (20%). Pyomyositis is an increasingly recognized infection of the striated muscles in HIV-infected patients. It affects almost exclusively males with advanced HIV infection (median CD4 count, 24). Most cases are due to Staphylococcus aureus (67%). Drainage of the involved muscle(s) accompanied by proper antibiotic treatment resulted in resolution of the infection in the majority of patients (90%). Although the incidence of musculoskeletal infections in patients with HIV from this and previous studies appears to be low (0.3%-3.5%), these infections add a significant morbidity and mortality in the affected individuals. Better understanding of their pathogenesis and clinical course would aid the proper diagnosis and management of these infections.

Septic and non-septic olecranon bursitis in the accident and emergency department--an approach to management

Olecranon bursitis is relatively common. One third of episodes are septic. Most of the remainder are non-septic, with occasional rheumatological causes. Trauma can cause both septic and non-septic olecranon bursitis. Clinical features are helpful in separating septic from non-septic olecranon bursitis, but there may be local erythema in both. Aspiration should be carried out in all cases, and if the presence of infection is still in doubt, microscopy, Gram staining, and culture of the aspirate will resolve the issue. Septic olecranon bursitis should be treated by aspiration, which may need to be repeated, and a long course of antibiotics. Some cases will need admission, and a few will need surgical treatment. Non-septic olecranon bursitis can be managed with aspiration alone. Non-steroidal anti-inflammatory drugs probably hasten symptomatic improvement. Intrabursal corticosteroids produce a rapid resolution but concern remains over their long term local effects. Recovery from septic olecranon bursitis can take months.
