Direct noninvasive assessment of the characteristics of coronary atherosclerotic plaques is important to improve cardiovascular risk stratification and to monitor the course of coronary artery disease. Coronary computed tomography angiography (CCTA) has become an effective tool for noninvasive evaluation of coronary artery calcium and plaque components. Using CCTA, atherosclerotic plaques can b...

Introduction: First branchial cleft anomalies manifest with duplication of the external auditory canal.   Case Report: This report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. External auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and...

Percutaneous coronary intervention of severely calcified lesions has historically been associated with major adverse cardiac event (MACE) rates as high as 30%. In the ORBIT II (Evaluate the Safety and Efficacy of OAS in Treating Severely Calcified Coronary Lesions) trial, treatment of de novo severely calcified lesions with the Diamondback 360° Coronary Orbital Atherectomy System (OAS) resulted...

OBJECTIVE To establish the correlations among the mineral components, progressive calcification process and clinical symptoms of calcific tendonitis. METHODS The morphology of the calcified deposits on the shoulders of 28 patients with calcific tendonitis was determined by high-resolution ultrasonography. The calcified deposit from each patient was aspirated and determined by the Fourier tran...

A 58-year-old man presented with stable angina pectoris. Coronary computed tomography angiography and coronary angiography revealed significant diffuse stenosis suggestive of coronary artery calcification at the proximal to midleft circumflex artery (Figures 1A, 1B). Percutaneous coronary intervention was performed. Frequency-domain optical coherence tomography revealed calcified plaques (Figur...

by determining normal ranges of spinal canal diameters we can make early diagnosis in persons who have lower diameters of spinal canal. these persons are predisposed to spinal canal stenosis that is a major cause of spinal radiculopathies. in different studies performed in several countries, minimum and maximum ranges of spinal canal diameters were different for each population. in this study, ...

Introduction: Navigator coronary MR angiography (CMRA) with steady-state free precession (SSFP) demonstrated good diagnostic accuracy of assessing coronary significant stenosis [1], but evaluation of the modality in detecting coronary atherosclerotic plaques was not reported. The purpose of this study was to investigate the ability of navigator CMRA wih SSFP in detecting coronary plaque with re...

A case of senile scleral plaques is reported in which expulsion of a calcified plaque anterior to the insertion of the medial horizontal rectus muscle gave rise to senile scleromalacia. Histopathological examination revealed a second calcified plaque at the site of the contralateral senile scleral plaque in this eye. This case indicates that senile scleromalacia is a scleral disease sui generis...

Nongalenic intradural arteriovenous fistulas, although uncommon, are clinically important. Choosing the appropriate therapeutic approach has been a controversial issue within the last decade.A 15-year-old male was presented with a calcified nongalenic arteriovenous fistula in the left parietal region, supplied by the left middle cerebral artery, and draining into the left lateral sinus. The pat...

Large calcified areas were observed in the articular discs of the temporomandibular joint from five patients suffering from articular dysfunctions. The calcified regions were always located inside the fibrous tissue of the discs. They had a woven bone-like morphological pattern and consisted of a compact mineralized tissue containing cells in irregular lacunae. In all the samples the calcified ...
