Hand and wrist radiographic indexes such as radial inclination, ulnar variance, carpal height ratio, and radial tilt play an important role in the diagnosis and management of medical disorders, so they should be modified regarding the population and race difference. This study aims to compare the normal radiologic wrist indexes in Mashhad population with other existing databases and define some...

acute lymphoblastic leukemia (all) is the most common form of childhood cancer representing 80-85% of all leukemia. we describe a 3 years old girl with pain, swelling and tenderness in extremities since 8 months prior to her present admission. x-ray of extremities revealed callus formation, osteopenia and site of healed fractures. bone marrow aspiration revealed all-l2 with normal peripheral sm...

OBJECTIVE We created an online computer system that allows radiologists to access the American College of Radiology (ACR) index for radiologic diagnoses from any Web browser. CONCLUSION A total of 11,260 indexes (10 anatomic, 722 pathologic, 90 subanatomic, and 10,438 subpathologic) were integrated into this online system. Users can navigate the entire ACR hierarchic indexing structure with e...

a young known case of multiple sclerosis was evaluated with chief complaint of gradually progressed left lower limb weakness over 3 weeks. pathologic examination of a mass in brain magnetic resonance imaging confirmed the diagnosis of glioblastoma multiforme (gbm). given the importance of the definite diagnosis of malignant glioma and its effect on patient’s management, gbm should be considered...

A new indexing method is presented which is capable of indexing multiple crystal lattices from narrow wedges of diffraction data. The method takes advantage of a simplification of Fourier transform-based methods that is applicable when the unit-cell dimensions are known a priori. The efficacy of this method is demonstrated with both semi-synthetic multi-lattice data and real multi-lattice data ...

We study the self-duality operator on conic 4-manifolds. The self-duality operator can be identified as a regular singular operator in the sense of Brüning and Seeley, based on which we construct its parametrizations and closed extensions. We also compute the indexes.

CONTEXT Stroke is a frequent cause of dysphagia. OBJECTIVE To evaluate in a tertiary care hospital the prevalence of swallowing dysfunction in stroke patients, to analyze factors associated with the dysfunction and to relate swallowing dysfunction to mortality 3 months after the stroke. METHODS Clinical evaluation of deglutition was performed in 212 consecutive patients with a medical and r...

PURPOSE This study examined whether any of a series of segmental and whole-word measures of articulatory competence captured more of the variance in impressionistic ratings of severity of involvement in speech delay. It also examined whether knowing the age of the child affected severity ratings. METHOD Ten very experienced speech-language pathologists rated severity of involvement from conve...

Tourism has become a very important and dynamic sector both in the world economy and particular in the developing countries. Its growth affects not only the activities directly linked to tourism but also other sectors. Tourism is already an important sector in some developing countries and will become so for others. Developing countries have been fast growing in tourism industry terms in the wo...
