As yet no unifying grading system for meningiomas has been adopted. We evaluate epidemiologic factors of meningioma in Iran & degree of agreement between the two commonly used grading systems namely WHO (2000) and Mahmood systems. During a 6-year period 238 meningiomas were selected and reviewed by two independent pathologists using both grading systems. 205(86.1%) cases were benign, 19(8%) aty...
Background and Purpose: We recently described an autosomal dominant syndrome characterized mainly by recurrent strokes and neuroimaging evidence of leukoencephalopathy. We now report the pathological findings in one of the affected subjects. Case Description: A 40-year-old woman experienced her first grand mal seizure in 1971. From 1983 on she suffered recurrent strokes, seizures, and psychiatr...
OBJECTIVE Frontotemporal lobar degeneration (FTLD) is characterized by impairments in social, behavioral, and/or language function, but postmortem studies indicate that multiple neuropathological entities lead to FTLD. This study assessed whether specific clinical features predict the underlying pathology. METHODS A clinicopathological correlation was performed on 90 consecutive patients with...
The patient, a 48-year-old black man, was first admitted to the hospital in late February 1993 because of fatigue, polyuria, polydipsia, and nocturia. To lose weight, he had been on a liquid diet and vitamins since November 1992 and had lost about 4.5 kg. He had remained active, working as an automobile mechanic. For several weeks before admission, he had been tired and weak and had noticed pol...
Prostatic atrophy is a benign lesion that may mimic adenocarcinoma histologically and on imaging. It is more frequent in the peripheral zone and has gained importance with the increasing use of needle biopsies. Diffuse atrophy occurs secondarily to radiotherapy and/or endocrine therapy. Inflammation and/or chronic local ischemia may cause focal atrophy with an increasing frequency in age. Atrop...
In this paper we propose a method for implementing a high-level interface for the synthesis and animation of animated virtual faces that is in full compliance with MPEG-4 specifications. This method allows us to implement the Simple Facial Object profile and part of the Calibration Facial Object Profile. In fact, starting from a facial wire-frame and from a set of configuration files, the devel...
A g-element for a graded R-module is a one-form with properties similar to a Lefschetz class in the cohomology ring of a compact complex projective manifold, except that the induced multiplication maps are injections instead of bijections. We show that if k(∆) is the face ring of the independence complex of a matroid and the characteristic of k is zero, then there is a non-empty Zariski open su...
