Comparative Evaluation of Bioactive Synthetic NovaBone Putty and Calcified Algae-derived Porous Hydroxyapatite Bone Grafts for the Treatment of Intrabony Defects.

Introduction: To compare and evaluate clinically and radio-graphically the bone regeneration and the amount of bone fill in intrabony component of periodontal osseous defects through the osteoconductive and osteostimulative effect of bioactive synthetic NovaBone Putty - CMF and osteoconductive effect of calcified algae-derived porous hydroxyapatite Frios Algi-pore bone grafts.

Materials And Methods: Twenty-two sites in 11 patients, within the age range of 25 to 60 years, showing intrabony defects were selected according to split mouth design and divided into group I (Frios Algipore) and group II (NovaBone Putty - CMF). All the selected sites were assessed with the clinical and radiographic parameters like plaque index, gingival index (full mouth and site specific), sulcus bleeding index, probing pocket depth, clinical attachment level, gingival recession, and radiographic bone fill.

Distal administration of very high doses of intracoronary adenosine for the treatment of resistant no-reflow.

No-reflow is a serious condition, and is associated with substantial morbidity and mortality after percutaneous coronary intervention. The most feared complication of no-reflow is a case of no-reflow that is resistant to multiple drug therapy. This condition usually occurs in patients with distal coronary disease or high thrombus burden.

Quadricuspid aortic valve with ascending aortic aneurysm: report of a case and discussion of embryological mechanisms.

Congenital quadricuspid aortic valves (QAVs) are rare phenomena. They are often associated with aortic insufficiency and significant morbidity. A QAV with an associated ascending aortic aneurysm is extremely rare, and these conditions might have a shared embryonic etiology.

Accelerometer-derived time intervals during various pacing modes in patients with biventricular pacemakers: comparison with normals.

Introduction: Changes due to biventricular pacing have been documented by shortening of QRS duration and echocardiography. Compared to normal ventricular activation, the presence of left bundle branch block (LBBB) results in a significant change in cardiac cycle time intervals. Some of these have been used to quantify the underlying cardiac dyssynchrony, assess the effects of biventricular pacing, and guide programming of ventricular pacing devices.

Relation between effects of adenosine on brachial artery reactivity and perfusion pattern in patients with known or suspected coronary artery disease.

This study examined the changes in brachial artery diameter and flow velocity in response to intravenous adenosine and compared the results to cuff occlusion and single-photon emission computed tomographic (SPECT) images. The change in diameter was less with adenosine than with cuff occlusion. There was no correlation between the presence of abnormal SPECT images and the responses to adenosine or cuff occlusion in either diameter or flow velocity.

Prevalence of diabetes mellitus and related conditions in Asian Indians living in the United States.

This study is the first attempt to evaluate the prevalence of diabetes mellitus and related conditions in Asian Indians living in the United States. A community-based survey of 1,046 Asian Indian immigrants living in and around the Atlanta metro area of Georgia was conducted and found an overall prevalence of diabetes mellitus of 18.3% (22.

Definitive diagnosis of cor triatriatum with common atrium by three-dimensional transesophageal echocardiography in an adult.

We describe an adult patient, in whom three-dimensional transesophageal echocardiography was able to make a definitive diagnosis of cor triatriatum associated with common atrium. The lesion mimicked a classical partial atrio-ventricular septal defect on both transthoracic and transesophageal two-dimensional echocardiography. We found only two cases in the literature describing the existence of cor triatriatum with common atrium, none diagnosed by echocardiography.

Multiple fistulae connecting the right coronary artery to the coronary sinus.

Right coronary artery to coronary sinus fistula is a rare anomaly. We present a unique case of an adult patient with multiple fistulae from the right coronary artery draining into the coronary sinus near the posterior left atrium-left ventricle junction, first suspected by transthoracic two-dimensional echocardiography. The multiple openings were not seen by any invasive or noninvasive techniques and were noted only at the time of surgery.

Mitral prosthetic inflow mimicking severe aortic regurgitation.

We describe two patients in whom mitral valve prosthetic inflow mimicked severe aortic regurgitation. Repeat transthoracic echocardiography using multiple transducer angulations and a narrow color Doppler sector angle in one patient and a color Doppler M-Mode study in the second patient proved useful in excluding the presence of severe aortic regurgitation.

Three-dimensional transesophageal echocardiographic delineation of ventricular septal aneurysm producing right ventricular outflow obstruction in an adult.

We report three-dimensional echocardiographic delineation of a congenital aneurysm of the membranous interventricular septum causing right ventricular outflow tract obstruction in an adult patient. To our knowledge, these findings have not been described before.

Prevalence of stroke and associated risk factors in Asian Indians living in the state of Georgia, United States of America.

This study is the first attempt to assess the prevalence of stroke and associated risk factors in Asian Indians living in the United States. The overall prevalence of stroke is 2.77% (men 3.
