Optometry's Role in Laser Vision Correctioncoakleylincoln
Although optometrists do not perform laser vision correction here in the United States, they can still provide a valuable role in this procedure that is gaining unprecedented popularity.
Why Eye check is important?
(Just close your eyes for a minute, we cant imagine living in darkness) That itself make us aware how important vision is !
7 reasons to check your vision;
Early detection of onset of disease.
Disease related complications can be avoided.
Silent Killers of vision like Glaucoma & Diabetic
Retinopathy can be detected & controlled.
Fluctuations in the power can be detected.
Working continuously in front of Computer can cause Computer Vision Syndrome & Dry eye.
So early detection can reduce the complications.
It is recommended to have eye check once in atleast 6 months.

If you are a secondary school student willing to learn more about successful career planning and more about the medical career, this presentation might help.
Traditionally, the field of optometry began with the primary focus of correcting refractive error through the use of spectacles. Modern day optometry, however, has evolved through time so that the educational curriculum additionally includes significant training in the diagnosis and management of ocular disease, in most of the countries of the world, where the profession is established and regulated.
Convergence insufficiency is one of the most frequently encountered binocular vision problem in children and adults. It is often associated with a variety of symptoms, including eyestrain, headaches, blurred vision, diplopia [double vision], sleepiness, difficulty concentrating, movement of print while reading, and loss of comprehension after short periods of reading or performing close activities. Have your doctor diagnose and treat this significant visual problem.

Analysis of a Career in Surgery
INTRODUCTION
A career as a surgeon is long, incredibly difficult, competitive, costly, and one of the most rewarding pursuits you can have in your life. Something not typically mentioned to aspiring pre-medical students is the complicated nature of applying to medical school and residency. Much more is required than just a set of good grades. Volunteer work in the community, leadership and research experience, writing and interviewing skills, are all necessary for a successful application to medical school. All of those things are required yet again, when applying to surgical residency.
Before digging into all those things, let’s look at the definition of a surgeon. The United States Department of Labor, Bureau of Labor Statisticsdescribes the surgical profession in the Occupational Outlook Handbook as the following: “Using a variety of instruments, a surgeon corrects physical deformities, repairs bone and tissue after injuries, or performs preventive or elective surgeries on patients.” This is a strict definition however; a more useful outlook would be to focus on what traits lend themselves to becoming a successful surgeon.
There is a useful list created by the American College of Surgeons (ACS), titled, “So You Want to Be A Surgeon: An Online Guide to Selecting and Matching with the Best Surgery Residency,” which aims at current medical students. The guide says that a surgeon should work well as a member of a team; enjoy quick patient outcomes; welcome increasing responsibility; excel at solving problems with quick thinking; be inspired by challenges; and love to learn new skills (American College of Surgeons). The ACS recommends looking into a surgical career if you believe some or all of those traits apply to you. However, there is no such thing as a “standard surgical resident” and the ACS points out that “surgeons are trained, not born.…Becoming a good surgeon is a lifelong process.”
For students interested in pursuing a surgical career, this analysis will explore the education, training, and career of a Surgeon. Information for objective analysis will be taken from multiple sources including article databases, government sources, a personal interview with an orthopedic surgeon, the American College of Sur.

CDSCO and Phamacovigilance {Regulatory body in India}NEHA GUPTA
The Central Drugs Standard Control Organization (CDSCO) is India's national regulatory body for pharmaceuticals and medical devices. Operating under the Directorate General of Health Services, Ministry of Health & Family Welfare, Government of India, the CDSCO is responsible for approving new drugs, conducting clinical trials, setting standards for drugs, controlling the quality of imported drugs, and coordinating the activities of State Drug Control Organizations by providing expert advice.
Pharmacovigilance, on the other hand, is the science and activities related to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems. The primary aim of pharmacovigilance is to ensure the safety and efficacy of medicines, thereby protecting public health.
In India, pharmacovigilance activities are monitored by the Pharmacovigilance Programme of India (PvPI), which works closely with CDSCO to collect, analyze, and act upon data regarding adverse drug reactions (ADRs). Together, they play a critical role in ensuring that the benefits of drugs outweigh their risks, maintaining high standards of patient safety, and promoting the rational use of medicines.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
