Octreotide, a potent synthetic long-acting somatostatin analogue, has been shown to have beneficial effect in thyroid eye disease (TED). Orbital scintigraphy using ocetreoscan-111 is useful study, which can be used visualize somatostatin-receptor-bearing cells and also select patients who might benefit from octreotide therapy. One major limitation of this therapy that the drug must administered parenterally several times daily. Lanreotide, new much longer duration action comparison with...

There has been a recent rise in the use of implantable cardiac devices, mostly valves but also electronic ones, such as pacemakers, and defibrillators. The increasing these devices had consequence raised incidence endocarditis, an infrequent morbid complication procedures. Thus, early diagnosis related infection endocarditis became pivotal for appropriate management. For diagnostic purposes, modified Duke criteria are widely used, which based on clinical imaging findings, addition to...
