“Objectives: Bent spine syndrome (BSS) is characterized by involuntary forward flexion of the

trunk in the standing position but not in the recumbent position. We assessed the causes of BSS based on findings in 63 patients.\n\nMethods: We retrospectively Lonafarnib reviewed the records of all patients with BSS evaluated at a teaching hospital in Toulouse, France, between 1995 and 2006. For each patient, we recorded the findings from the following investigations: physical examination, electromyogram (EMG), creatine phosphokinase (CPK) assay, computed tomography (CT), and surgical muscle biopsy.\n\nResults: We identified 63 patients, 46 females and 17 males, with a mean age of 70 +/- 6.9 years. Among them, 40 had delayed-onset paraspinal myopathy, with fatty infiltration predominantly affecting the paraspinal muscles. In 40% of these patients, CT disclosed mild fatty infiltration of the gluteal and posterior thigh and leg muscles in addition to the paraspinal muscle abnormalities. Paraspinal muscle histology showed lobular endomysial fibrosis, as previously described and ruled out other forms of muscle dystrophy. The remaining 23 patients (14 females and nine males) had either another neurological disease or myopathic involvement of other muscles, with a definite

diagnosis; nevertheless, forward bending of the trunk was the most prominent symptom and the reason for the initial physician visit.\n\nConclusion: In our case-series, delayed-onset paraspinal myopathy accounted for 64% of cases of BSS. The most informative AZD6244 investigation was CT, which showed a patchy decrease in paraspinal muscle

density. (C) 2010 Published by Elsevier Masson SAS on behalf of the Societe Francaise de Rhumatologie.”
“The purpose of this study was to click here identify the exercise intensity equivalent to the aerobic/anaerobic metabolic transition in obese rats of both genders using the maximal lactate steady state (MLSS) protocol. Four groups of rats were tested on MLSS protocol (swimming exercise): male control n=10, female control n=10, male obese n=10 and female obese n=10, after suitable adaptation to exercise in liquid medium and obesity induction by monossodic glutamate (MSG) administration. The obese groups had significant increase in subcutaneous adipose tissue as well as mesenteric and retroperitoneal fat depots comparing to the control groups. The Lee index was higher in the obese animals in comparison to their respective controls. It was possible to identify the MLSS at 6.0% of body weight for both obese groups. Concerning the female control group, the MLSS was determined at the intensity of 5.0% of body weight, whereas for the male control at 4.5% of body weight. It was concluded that obesity induced by MSG interferes in lactate kinetics during exercise and alters the effort intensity corresponding to the metabolic transition in both genders.
