Bilateral concomitant femoral neck stress fracture in a sedentary patient with anorexia nervosa.

Unlabelled: A 27 years old sedentary woman presented bilateral femoral neck stress fractures after having clinically recovered from anorexia nervosa and was treated with bilateral internal fixation.

Conclusion: Although light exercise is usually considered after recovery from anorexia nervosa to improve bone quality, this case of a patient suggests that weight gain, per se, could increase the stress fracture risk. Because of the physiological and psychological characteristics, these patients should be treated with a multi-disciplinary approach.

Background concentrations and reference values for heavy metals in soils of Cuba.

The potential threat of heavy metals to human health has led to many studies on permissible levels of these elements in soils. The objective of this study was to establish quality reference values (QRVs) for Cd, Pb, Zn, Cu, Ni, Cr, Fe, Mn, As, Hg, V, Ba, Sb, Ag, Co, and Mo in soils of Cuba. Geochemical associations between trace elements and Fe were also studied, aiming to provide an index for establishing background concentrations of metals in soils.
