Nanotechnology- future prospect in recent medicine: a review

Any damage at molecular or cellular level is the major culprit for disease & ill health. Nanotechnology, “the manufacturing technology of the 21st century," helps us economically build a broad range of complex molecular machines by manipulating matter on an atomic and molecular scale. Nanotech may be able to create many new materials and devices with at least one dimension sized from 1 to 100 nanometres with a vast range of applications, such as in medicine, electronics, biomaterials and energy production. Lots of new possibilities come into account in relation to use of nanotechnology in medicines. Nanotechnology in medicine involves applications of nanoparticles, also involves nano-robots to make repairs at the cellular levels. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials

Chronic pain, its management and psychological issues: A review

Chronic pain is one of the most prevalent, disabling conditions both in clinical and psychological aspects and yet often remains inadequately treateddue to cost reasons. Moreover, chronic pain commonly occurs in conjunction with depression, anxiety and somatoform disorders. Chronic andrecurrent pain not associated with a disease is very common in childhood and adolescence, but there are very less studies and analysis has been doneon chronic pain epidemiology and management. As pain is the important factor influencing quality of life and also the reason for which a person seekthe advice of physician even require hospitalization that is why this systematic review highlights the different types of chronic pain, epidemiology,pathophysiology, and management of chronic pain along with psychological issues associated with it.Keywords: Pain, Psychological aspects, Epidemiology, Somatoform disor
