Dr. S. Ramakrishnan is a Senior Consultant Nephrologist and is the Head of department Nephrology at NU Hospitals, Bangalore completed MBBS in Thanjavur Medical College in 1985 and postgraduate in General Medicine in Stanley Medical College Chennai in 1990. He is interested in all branches of General Medicine and chose Nephrology for further specialization as this field had a connection with all other branches of General Medicine. He completed the higher speciality course in Madras medical College in 1995. After a brief experience as Tutor of Nephrology in a teaching hospital and subsequently as Specialist in Nephrologist in a Middle East country, he joined NU Hospitals in 2004. His special interest includes the evolution of better infection control practices and safety practices in the patient’s environment and demography of patients with kidney disease. With significant help from the Hospital, a number of policies and protocols on infection control have been developed and implemented. One of the major outcomes of these practices was significant reduction in the incidence of Hepatitis C infection, a blood-borne viral infection that can be transmitted among patients on maintenance haemodialysis (this infection had been a Nephrologists’ nightmare until the development of newer antiviral drugs for the treatment a couple of years ago) over the past few years.
