ABSTRACT
Cancer therapy is a fast-emerging biomedical paradigm that elevates the diagnostic and therapeutic po-tential of a nanovector for identification,monitoring,targeting,and post-treatment response analysis.Nanovectors of superparamagnetic iron oxide nanoparticles(SPION)are of tremendous significance in cancer therapy because of their inherited high surface area,high reactivity,biocompatibility,superior contrast,and magnetic and photo-inducibility properties.In addition to a brief introduction,we summarize various progressive aspects of nanomagnets pertaining to their production with an emphasis on sustainable biomimetic approaches.Post-synthesis particulate and surface alterations in terms of pharmaco-affinity,liquid accessibility,and biocompatibility to facilitate cancer therapy are highlighted.SPION parameters including particle contrast,core-fusions,surface area,reactivity,photosensitivity,photodynamics,and photothermal properties,which facilitate diverse cancer diagnostics,are discussed.We also elaborate on the concept of magnetism to selectively focus chemotherapeutics on tumors,cell sorting,purification of bio-entities,and elimination of toxins.Finally,while addressing the toxicity of nanomaterials,the advent of ultrasmall nanomagnets as a healthier alternative with superior properties and compatible cellular in-teractions is reviewed.In summary,these discussions spotlight the versatility and integration of multi-tasking nanomagnets and ultrasmall nanomagnets for diverse cancer theragnostics.
ABSTRACT
Cardiac echinococcosis is a rare disease. Depending on the location of hydatid cyst in the heart, clinical presentation can be an asymptomatic case or lethal stroke, arrhythmias, valvular dysfunction, cardiac tamponade, cardiac failure, shock, and even death. Treatment of choice for cardiac hydatid cysts is surgical excision, even in an asymptomatic patient. We present a case report of an asymptomatic case of off-pump removal of intramyocardial hydatid cyst. A 21-year-old male presented asymptomatically and was diagnosed with a hydatid cyst incidentally during a regular checkup. Echocardiography and cardiac computed tomography angiography images demonstrated an intramyocardial hydatid cyst on the lateral aspect of the left ventricle with slight extension over the anterior and posterior regions. Important aspects of diagnosis and management specific to cardiac hydatid cyst along with the review of literature have been discussed.
