Greetings from the editorial board of Chettinad Health City Medical Journal It gives us immense pleasure to bring out the final issue of volume 7. We take this opportunity to thank the authors and reviewers for their unceasing support. This issue has articles from various specialties, with three articles from cardiothoracic-vascular surgery. The perspective article on heart valve therapy explains about the evolution of valvular surgery in terms of advances in the procedure and the prosthetic valves used.

The significance of teaching-learning methodology in fulfilling the goals of competency based medical education.

This study was conducted to analyze the prevalence of color vision deficiency among a group of medical students. In this prospective cross-sectional study, 300 undergraduate medical students in the age group of 19-22 years were screened for Color Vision Deficiency (CVD) using Ishihara‘s Pseudo-isochromatic chart. Students with defective color vision were identified.

On March 11, 1960, 32 year old Nina Braunwald made history when she became the first cardiac surgeon of either sex to replace the mitral valve.

As a young person, I was always interested in both history and science. Towards the end of high school, I was keen to become a physicist or astronomer, but in the final year of high school, my best friend convinced me that we both should do medicine together.

About 15 to 20% of ovarian epithelial tumors are “borderline”. Majority of them are serous or mucinous. They pose significant problems in diagnosis as there are no specific clinical features or investigations to ascertain the “borderline” nature. For a frozen section diagnosis an expert pathologist is needed. Surgical staging with radical surgery ensures near 100% survival in stage I. Even in advanced stage without invasive implants survival is excellent. A third of Borderline Ovarian Tumors(BOT) occur in women under 40 years. Fertility sparing surgery in early stage carries good prognosis. Laparoscopic surgery can also be undertaken without adverse effects. There is no role for adjuvant chemo/radiotherapy except probably when there are invasive implants. Prognostic factors include advanced stage at surgery, suboptimal debulking, invasive implants and micropapillary architecture. Long follow up has been recommended as recurrences are reported even after decades.

This article focuses on the discussion of the term “Polypharmacy”, the rationality of polymedication, its limitations, the understanding of the concept in other systems of medicine and suggestions to minimize polymedication.

It was over a hundred years ago that Sir Lauder Brunton, a visionary cardiologist first envisioned surgical intervention for valvular heart disease. The first procedure performed for the relief of heart valve disease was Closed Mitral Valvotomy, which was developed by bold mavericks like Souttar, Bailey and Brock.
