OBJECT Reconstruction after anterior cervical decompression has involved the use of tricortical iliac crest bone or fibular strut grafts, but has been associated with significant morbidity. In this study the authors evaluated the efficacy of titanium mesh cages (TMCs) for stability and fusion following anterior cervical corpectomy. METHODS Thirty-seven(More)
We present an unusual case of weaning failure. A 67-yr-old man presented with confusion, hyponatremia, and hypercapnic respiratory failure that necessitated mechanical ventilation. CXR revealed a right hilar mass (non-small-cell carcinoma on biopsy). Level of consciousness improved with treatment of his hyponatremia. However, attempts at weaning were(More)
We report a patient with relapsing-remitting meningoencephalitis secondary to neuro-Behcet disease which resulted in recurrent brainstem encephalitis. MRI revealed increased signal intensity on the proton density and T2-weighted images and gadolinium enhancement during relapses. Autopsy revealed acute on chronic meningoencephalomyelitis involving the entire(More)
BACKGROUND Pituitary apoplexy, a rare but life-threatening disorder, is characterized by the abrupt destruction of pituitary tissue secondary to infarction or hemorrhage of the gland itself. Its clinical features include severe headache, stiff neck, fever, visual disturbances, and symptoms of hypoadrenalism. OBJECTIVES To assess how pituitary apoplexy may(More)
A new Density-Functional (DF) formula is constructed for atoms. The kinetic energy of the electrons is divided into two parts: the kinetic self-energy and the orthogonalization energy where these concepts are borrowed from the pseudopotential theory. For the radial part of the orthogonalization energy which replaces the radial part of the Fermi-energy of(More)
Heterotopic calcification or ossification of the soft tissues adjacent to the lesser trochanter was observed in the radiographs of 4 patients during a retrospective review of the records of 68 patients with Perthes' disease. This abnormality has since been seen in one other patient with Perthes' disease and in five with spastic quadriplegia. All 10 patients(More)
Intracranial gas is a common finding on postcraniotomy computed tomography scans. It can also be found in a wide variety of other benign and life-threatening clinical settings. Because intracranial gas is never normal, its presence must be explained. This pictorial essay describes the imaging features of intracranial gas and demonstrates the findings for(More)
