The differential diagnosis is difficult to establish when, particularly, movement disorder presents as the initial manifestation of multiple sclerosis. Video-electroencephalography monitoring is the gold-standard method for the differential diagnosis of epileptic and paroxysmal nonepileptic events, including movement disorders and psychogenic seizures. This article presents a patient with paroxysmal dystonia secondary to multiple sclerosis who previously was diagnosed and treated as having conversion disorder and epilepsy. The utility of video-electroencephalography monitoring during the process of differential learn more diagnosis is discussed.”
“Purpose:
To use finite element modeling based on flat-panel volume computed tomography (CT) and bone mineral density (BMD) provided by dual-energy x-ray absorptiometry (DXA) to compare bone
failure load, stiffness, and trabecular structure in women with anorexia nervosa (AN) and age-matched normal-weight control subjects.
Materials and Methods: The study was approved by the institutional review board and complied with HIPAA guidelines. Informed consent was obtained. Fourteen women, eight with AN (mean age, 26.6 years) and six control subjects (mean age, 26.3 years), underwent flat-panel volume CT of the distal radius to determine apparent trabecular bone volume fraction (BV/TV), apparent trabecular number (TbN), apparent trabecular thickness (TbTh), Dinaciclib and apparent trabecular separation (TbSp). Bone strength and stiffness were calculated from uniaxial compression tests by using finite element models created from flat-panel volume CT. DXA was used to determine BMD of
the radius, lumbar spine, and hip. Means +/- standard deviations of all variables were calculated for both groups and compared (Student t test). Univariate regression analysis and stepwise regression modeling were performed.
Results: Patients with AN had lower values for stiffness (284.77 kN/mm +/- 76.14 vs 389.97 kN/mm +/- 84.90, P=.04), failure load (4.98 kN +/- 1.23 vs 7.01 kN +/- 1.52, P=.02), BV/TV (0.32% +/- 0.09 vs 0.44% +/- 0.02, P=.007), and TbN (1.15 mm(-3) +/- 0.20 vs 1.43 mm(-3) +/- www.selleckchem.com/products/anlotinib-al3818.html 0.13, P=.008) and higher values for TbSp (0.62 mm +/- 0.20 vs 0.40 mm +/- 0.04, P =.02) compared with normal-weight control subjects. TbTh was lower in women with AN (P=.1). BMD measurements were significantly lower for the AN group. BMD measurements and trabecular parameters (except TbTh) correlated with stiffness and failure load (r = 0.58 to 0.83).
Conclusion: Failure load and stiffness are abnormal in women with AN compared with those in normal-weight control subjects and correlate with BMD and trabecular parameters. (C) RSNA, 2010″
