It brings together medical practitioners of all grades, from all branches of medicine in Sri Lanka. The SLMA started life as the "Ceylon Branch of the British Medical Association" on 17th December 1887 with 65 members on its roll, and Dr. P D Anthoniz as its first President. However, the moving force behind its inception was Dr. W R Kynsey (later Sir William Kynsey), who persuaded 15 doctors to meet on 26th February 1887, at the Colonial Medical Library on Maradana Road, Colombo and resolve to form that Association. He had declined to be the first President as he was going abroad on furlough. The change of name to "Ceylon Medical Association" came in 1951, and in 1972 when Sri Lanka became a Republic, the name changed again to the "Sri Lanka Medical Association". The SLMA office is at "Wijerama House", named after Dr. E M Wijerama, who formally gifted the house he lived in, at McCarthy Road (now Wijerama Mawatha) to the Association in 1964. Although his offer was made in writing in October 1957, resolution of the many issues that arose took 7 years! The Ceylon Medical Journal was first published in August 1887, and fittingly, the first article in the first issue was authored by Dr. W R Kynsey. The name changed to Journal of the Ceylon Branch of the British Medical Association in 1904, but changed to its pristine appellation in 1952, and 1 SLMA 128th Anniversary International Medical Congress, 2015 continues to be published as the Ceylon Medical Journal (CMJ). At its 127th year, it is the oldest surviving English medical journal in Asia and Australasia, and the leading scientific journal in Sri Lanka. The CMJ is indexed in BIOSIS, CAB International, EMBASE and the Index Medicus. CMJ's editorial policies and quality are of international standards, and it is listed by the International Committee of Medical Journal Editors as conforming to their editorial guidelines. The historic Sri Lanka Medical Library, which is over 169 years old, is also accommodated in Wijerama House. The Sri Lanka Clinical Trials Registry, started as recently as 2006, has achieved recognition from the World Health Organisation by being selected as a WHO Primary Clinical Trials Registry. The Anniversary International Medical Congress is the most important activity of the SLMA’s calendar. It has been held uninterrupted every year since it was started in 1937 to mark the 50th anniversary of the association. The SLMA today is a vibrant organization. It is run by the President and the Council. There are many committees dealing with its day to day affairs. These include the Finance, Management and Housing Committee; Corporate Planning Committee; Ethics Review Committee; Ethics Committee; Honours Committee; Research Promotion Committee; the Sri Lanka Clinical Trials Registry Management Committee; and the Ceylon Medical Journal Editorial Board. The SLMA also has Expert Committees which deals with various subject areas. They include Expert Committees on Communicable Diseases; Disabilities; Ergonomics; Health Equity; Health Management; Herbal Medicine; Medicinal Drugs; Non Communicable Diseases; Prevention of Road Traffic Accidents; Snake Bite; Tobacco, Alcohol and Illicit drugs; and Women’s Health. 2 SLMA 128th Anniversary International Medical Congress, 2015 COUNCIL OF THE SRI LANKA MEDICAL ASSOCIATION 2015 President Professor Jennifer Perera President Elect Dr. Iyanthi Abeyewickreme Immediate Past President Dr. Palitha Abeykoon Honorary Secretary Dr. Ranil Jayawardena Vice Presidents Dr. Padma S Gunaratne Dr. Navoda Atapattu Honorary Assistant Secretaries Dr. A A H Priyani Dr. Shamini Prathapan Dr. Sudarshi Seneviratne Professor Sharmini Gunawardena Honorary Treasurer Dr. Samanthi de SIlva Honorary Assistant Treasurer Dr. Asiri Rodrigo Public Relations Officer Dr. Kalyani Guruge Past Presidents’ Representative Dr. J B Peiris Council Members Dr. Dennis J Aloysius Dr. S B Agampodi Dr. M S G De Silva Professor S D Dharmaratne Professor Vajira HW Dissanayake Dr. Christo Fernando Dr. T R Fernando Dr. Sahan I T Guruge Professor Deepika Fernando Dr Amaya Ellawala Dr. N R Hewageegana Dr. Ruvaiz Haniffa Dr. Lucian Jayasuriya Dr. Kapila Jayaratne Dr. Pradeepa Jayawardane Professor Saroj Jayasinghe Dr. Indika Karunathilake Dr. Chiranthi K Liyanage Dr. B J C Perera Dr. Priyanga Ranasinghe Dr. Shyamalee Samaranayaka Dr. Sunil Seneviratne Epa Dr. Pramilla Senanayake Dr. Sumithra Tissera Dr. Gamini Walgampaya Dr. Deepal Wijesooriya Social Secretaries Dr. Lasantha Malavige Dr. Preethi Wijegoonewardene Co-Editors (CMJ) Dr. Anuruddha Abeygunasekera Professor Varuni de Silva 3 SLMA 128th Anniversary International Medical Congress, 2015 COUNCIL OF THE SRI LANKA MEDICAL ASSOCIATION 2015 SLMA 128th Anniversary International Medical Congress, 2015 Seated Left - Right: Dr. Pramilla Senanayake, Dr. Kalyani Guruge (Public Relations Officer), Dr. Dennis J Aloysius, Dr. Lucian Jayasuriya, Prof. Vajira HW Dissanayake, Dr. Palitha Abeykoon (Immediate Past President), Prof. Jennifer Perera (President, SLMA), Dr. Iyanthi Abeyewickreme (President Elect), Dr. Navoda Atapattu (Vice President), Dr. Padma S.
