The clinical and radiographic features of hip disease in 76 patients with definite ankylosing spondylitis have been studied. Symptomatic hip involvement occurred late in the course of the disease, with a mean delay after the onset of 12 years in males and 7 years in females. Patients with disease onset before the age of 20 developed hip symptoms at an earlier stage. Associated diseases included...

introduction: papillon-lefèvre syndrome(pls) characterized by palmoplantar hyperkeratosis is a rare autosomal recessive genetic disorder with rapidly progressive periodontitis and premature loss of both deciduous and permanent teeth. in this study, we report the clinical and radiographic features of papillon-lefèvre syndrome in an 11- year-old girl and we also discuss the history and various th...

ameloblastomas are tumors of odontogenic epithelial origin. the term unicystic ameloblastoma is used to describe cystic lesions with clinico-radiographic features resembling an odontogenic cyst, but histologically showing the presence of ameloblastomatous epithelium lining part of the cyst cavity. a large majority of lesions are found in the mandible, and usually cause a painless swelling of th...

dentin dysplasia is an exceptionally rare, autosomal-dominant, hereditary condition, primarily characterized by defective dentin formation affecting both the deciduous and permanent dentitions. the etiology remains imprecise to date, in spite of the numerous hypotheses put forward and the constant updates on this condition. this case report of type i dentin dysplasia exhibits radiographic fi nd...

background: several factors are associated with the development or exacerbation of pain in knee osteoarthritis (koa). in this study, we reviewed this context based on relevant studies. methods: recent published studies which have addressed the relationship between pain and koa were summarized. results: correlates of the clinical, demographic features, laboratory tests and abnormalities on radio...

Image processing and image analysis are the main aspects for obtaining information from digital image owing to the fact that this techniques give the desired details in most of the applications generally and Non-Destructive testing specifically. This paper presents a proposed method for the automatic detection of weld defects in radiographic images. Firstly, the radiographic images were enhance...

Central hemangioma of the mandible and maxilla is extremely rare. Although the mucosal and soft tissue lesions are readily suspected by their clinical appearance, the intrabony lesions may be difficult to distinguish visually. The clinical and radiographic presentation is relatively nonspecific; therefore, a proper diagnosis has to be made. The management of central hemangioma is difficult beca...

Radiographic testing method is often used for detecting defects as a non-destructive testing method. In this paper, an automatic computer-aided detection system based on Support Vector Machine (SVM) was implemented to detect welding defects in radiographic images. After extracting potential defects, two group features: texture features and morphological features are extracted. Afterwards SVM cr...

OBJECTIVE To examine the diagnostic accuracy of hip internal rotation, hip flexion, and knee flexion measurements for the presence of osteophytosis and joint space narrowing (JSN) in early symptomatic osteoarthritis (OA). METHODS The baseline data for 598 participants of the Cohort Hip & Cohort Knee study were used. Participants underwent a standardized physical and radiographic examination. ...
