Complex regional pain syndrome and bone marrow oedema syndrome: family ties potentially closer than expected.

Complex regional pain syndrome (CRPS) and bone marrow edema syndrome (BMES) are two rare conditions that are still being discussed. They are generally considered as two distinct entities, yet they share similarities such as a homogeneous bone marrow edema is also often found in the early phase of CRPS. We present the case of a 41-year-old man with CRPS after a foot fracture followed by the development of painful BMES of the ipsilateral knee and hip a few weeks later. The search for another pathology was negative. After pamidronate infusions, the evolution was spectacular: the disappearance of hip pain at 1 month and more than 50% reduction in knee and foot pain at 2 months. At final follow-up (1 year), the patient was asymptomatic. This case reinforces the idea of a possible link between CRPS and BMES probably through similar trabecular bone involvement. Imaging remains useful in diagnosis of CRPS

Comparaison de la fructosamine et de l'HbA1c pour l'évaluation du contrôle métabolique du diabète [Comparison of fructosamine and Hba1c for the evaluation of metabolic control of diabetic patients]

Fructosamine values, and the influence thereon of age, BMI and sex, were determined in 384 nondiabetic individuals aged between 20 and 95 years. In this control group mean F levels were 2.45 +/- 0.25 mmol/l and were age-related only, rising from 2.3 in the second decade to 2.6 in the eighth. We compared F and HbA1c in 135 diabetic patients. F correlated with HbA1c in the diabetic group (r = 0.76, p less than 0.001). Because of its biological properties fructosamine could become a useful pointer in the metabolic follow-up of diabetic patients, especially where clinic visits are frequent
