[Pyomyositis in children: Two cases of Staphylococcus aureus infection].

Pyomyositis is a term used to denote primary pyogenic infection of a skeletal muscle. It is a rare disease that was first described in immunodeficient patients living in tropical climates. Lately, however, cases involving healthy children have been described in temperate climates.

Association between hip morphology and prevalence, clinical severity and progression of hip osteoarthritis over 3 years: The knee and hip osteoarthritis long-term assessment cohort results.

Objective: To assess the effects of variations in hip morphology on prevalence, clinical severity and progression of hip osteoarthritis.

Methods: From 2007 to 2009, we conducted a study of 242 patients aged between 40 and 75 years with symptomatic lower limb osteoarthritis, as part of a population-based osteoarthritis cohort study in France. Standard radiographs of both hips were obtained at baseline and at three years.

Relationship between hip dysplasia, pain, and osteoarthritis in a cohort of patients with hip symptoms.

Objective: The relationship between acetabular dysplasia (HD) and hip osteoarthritis (OA) remains unclear, especially for mild forms of dysplasia. Our objectives were to estimate the prevalence of HD in a population-based sample with symptoms and to evaluate potential associations linking HD, hip OA, and hip pain.

Methods: Individuals 40 to 75 years of age with symptoms in 1 or both hips were recruited during a multiregional prevalence survey.

Concordance between clinical and ultrasound findings in rheumatoid arthritis.

Background: Clinical joint examination is less time-consuming than ultrasound in rheumatoid arthritis. Knowledge of clinical and ultrasound concordance of joints groups could help in selecting joints for a best ultrasonographic assessment.

Objective: To evaluate concordance between clinical examination and ultrasound of joints in a heterogeneous group of patients with rheumatoid arthritis.

Role of SPECT/CT compared with MRI in the diagnosis and management of patients with wrist trauma occult fractures.

Background: The diagnosis of wrist fractures, especially scaphoid fractures, remains a challenge because of nonunion risk. Currently, new hybrid technologies are emerging such as SPECT/CT systems, which combine functional and anatomical data sets. So, we wanted to evaluate the utility of SPECT/CT in the management of occult carpal fractures.
