[Treatment of ankylosing spondylitis with anti-TNFalpha agents].

Non steroidal antiinflammatory drugs (NSAID) used to be the only drugs active in ankylosing spondylarthritis (AS). However, they are inadequate or ill-tolerated in many patients, and have no proven impact on disease-related structural changes. Clinical trials have recently shown the impressive efficacy of two anti-TNFalpha agents (infliximab and etanercept) in patients with NSAID-resistant SA.

Bone density, parathyroid hormone, calcium and vitamin D nutritional status of institutionalized elderly subjects.

Introduction: Osteoporosis is characterized by a decrease in bone mass and a change in bone microarchitecture. This causes skeletal fragility and may result in fractures. Fractures of the femur neck (FM) are frequent and have major consequences in terms of morbidity and mortality in elderly subjects.

Femoral neuropathy secondary to ossification of the ligamentum flavum.

Radiculopathy resulting from ossification of the ligamentum flavum (OLF) is extremely rare and concerns only intercostal neuralgias. We describe a 37-year-old Caucasian woman with a lumbar radiculopathy revealing an OLF. Her symptoms were completely and definitively relieved by surgery.
