In the United States, rat-bite fever is a rare systemic illness principally caused by Streptobacillus moniliformis, an organism found in the nasopharyngeal flora of rodents. Infection through direct exposure to rat excreta such as saliva, urine, or feces can lead to fever, rash, and an asymmetric migratory polyarthritis. As rodents are becoming more popular as pets, more pediatric cases are bei...

This retrospective study analyzed the clinical, bacteriological, and radiological features of pediatric patients with acute hematogenous osteomyelitis and septic arthritis. Eighty-four patients with septic arthritis and 39 with acute hematogenous osteomyelitis were enrolled. Their age ranged from 13 days to 17 years. In patients with septic arthritis, the hip joint was the most often infected s...

We performed 52 total hip replacements in 52 patients using a cementless acetabular component combined with a circumferential osteotomy of the medial acetabular wall for the late sequelae of childhood septic arthritis of the hip. The mean age of the patients at operation was 44.5 years (22 to 66) and the mean follow-up was 7.8 years (5 to 11.8). The mean improvement in the Harris Hip Score was ...

Hip joint instability can be secondary to congenital hip pathologies like developmental dysplasia (DDH) or acquired such as sequel of infective or neoplastic process. An unstable hip is usually associated with loss of bone from the proximal femur, proximal migration of the femur, lower-extremity length discrepancy, abnormal gait, and pain. In this case series of 37 patients coming to our instit...

We report a case of polyarthritis with axial involvement in a young female patient treated for acute lymphoblastic leukemia. Detection in the hip fluid of Ureaplasma urealyticum by broad-range PCR followed by electrospray ionization mass spectrometry allowed the diagnosis of septic arthritis and ad integrum recovery upon adapted antibiotic therapy.

On the basis of primarily consensus due to lack of relevant clinical studies, the most important evaluative step for knee pain is to identify any emergent conditions, including limb- and life-threatening disorders (septic arthritis, osteomyelitis, and malignancy), hip pathology, or conditions associated with effusions.

series, Staphylococcus aureus was the primary cause of bacterial arthritis in 40% of cases from England and Wales, 56% of cases from France, and 37% of cases from tropical Australia (panel 1). S aureus cause 80% of joint infections in patients with concurrent rheumatoid arthritis and in those with diabetes. This microbe is also the primary pathogen in hip infections and in polyarticular septic ...

The intraoperative appearance of rapidly destructive osteoarthritis and septic arthritis can be similar. Three patients at our institution demonstrated preoperative or intraoperative findings potentially consistent with infection during primary total hip arthroplasty; however, none of these patients were found to have an actual infection. One of these patients underwent an unnecessary 2-stage t...

We present a case of septic arthritis of the hip caused by Candida albicans in a 24-year-old woman. This is the first report of a Candida infection of the hip in a patient without any predisposing factors. She underwent a two-stage total hip arthroplasty three years after the onset of the infection. An elevated plasma level of beta-D-glucan suggested Candida as the infecting organism and the di...
