A 34-year-old woman on long-term hemodialysis, with secondary HPT, presented with a 9-month history of persistent neck pain. Radiographs of the cervical spine revealed an expansive osteolytic lesion in the posterior arch of the second cervical vertebra. MR imaging revealed an expansive mass on C2 affecting the vertebral body, odontoid process, right pedicle, laminas, and spinous process; there were no signs of spinal edema. A CT-guided needle biopsy of the lesion showed destruction of trabecular bone, infiltration of the fibroblastic cells,

and abundant osteoclast-like multinucleated giant cells with hemorrhage and hemosiderin pigment, and the diagnosis of brown tumor was made. Cervical pain disappeared within a few days of parathyroidectomy, and rapid remineralization of C2 was evident within a ABT-263 concentration few months. BT must always www.selleckchem.com/products/Gefitinib.html be considered in the context of hyperparathyroidism and osteolytic lesions. Vertebral BT can be particularly devastating due to medullar compression symptoms. Regression or complete disappearance of these lesions after parathyroidectomy is common, but prompt surgical decompression is necessary in case of medullar compression symptoms.”
“In this paper, we report the design, fabrication, and measurement of a metamaterial absorber

that is constructed of a periodic array of tetra-arrow resonators (TARs) printed on a dielectric material backed by a metal ground. The TAR absorber can operate at three different resonant modes. By adjusting geometry parameters of the structure, we can obtain a dual-band, polarization-insensitive, wide-angle thin absorber or a single band but ultra-miniature absorber that corresponds to three different resonant modes. Waveguide experiments are conducted to verify the proposed designs

effectively. The measurement results show that all three absorptivity peaks come near to perfection. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3638118]“
“We sought to characterize risk factors of urinary incontinence (UI) during pregnancy and the postpartum period in primiparous women in China.

We OSI-906 enrolled 10,098 women from the seven regions of China a parts per thousand yen28 weeks’ gestation from September 2007 to May 2009 and administered the Bristol Female Lower Urinary Tract Symptoms questionnaire to estimate the presence of different types of UI during late pregnancy (37 to 42 weeks’ gestation) and at 6 weeks and 6 months postpartum. We also collected details of pregnancy and childbirth and demographic data. McNemar’s test, multinomial logistic regression models, and binary logistic regression models were used.

Multivariable analysis revealed six independent risk factors for SUI: age, more frequent exercise, alcohol consumption, higher body mass index, larger waist circumference, and history of constipation. For those with no UI in late pregnancy, 3.7% and 3.0% developed new cases at 6 weeks and 6 months postpartum, respectively.
