WHAT IS FORENSIC MEDICINE? þ Forensic medicine (synonym: legal medicine) is a fundamental and independent part of medicine dealing with the interaction of medical science and practice with the law. The practice of using the terms "forensic medicine" and "medical jurisprudence" ha s led to considerable confusion as to their correct meaning. These definitions are closely related but somewhat different: Ø Medical jurisprudence is that part of law which is concerned with the regulations governing the professional practice of the doctor of medicine. Ø Forensic (or legal) medicine is that part of medical science which is employed by the legal authorities for the solution of legal problems. Theoretically all branches of medicine may be included in this definition and any doctor who te stifies in court in his professional capacity can be considered a practitioner of forensic medicine. But the term is us u- ally restricted to that specialized branch of medical knowledge used by physicians officially employed by the local government of a community when they investigate suspicious and violent deaths, or non-fatal cases such as rapes, sexual offenses or abortions which may subsequently come before the courts. The word "forensic" means "situated on forum romanum". Historically this famous market-place of an- cient Roma played an important part in law and administrative activities that time. Forensic medicine provides a tight connection between medical science and the law. Medical science can assist the administration of justice in: Ø civil matters Ø criminal matters. Forensic medicine is dealing with living and dead people, in order to solve these problems: w examination and evaluation of injury (disease) w effects of injury (disease) w cause of death w identification of living and dead w paternity w pregnancy and abortion w medical malpractice etc. Branches of medicine which assist in medico-legal problems are: anatomy, histology, pathology, dentistry, physiology, biochemistry, pharmacology, traumatology, resuscitation, haematology, genetics, microbiology, obstetrics, paediatrics, psychiatry, sexuology etc. Forensic medicine borrows methods of investigation from various natural and other sciences: anthropo- logy, biomechanics, analytical chemistry, entomology, criminology etc. Forensic medicine has its own branches: traffic medicine, alcohology, forensic thanatology, forensic toxi- cology, forensic genetics, forensic anthropology etc. (see tab. 1). Forensic medicine participates in prevention of negative social phenomena: Ü criminal violence towards health and life Ü traffic and working accidents Ü chronic alcoholism Ü drug abuse Ü suicides etc. The main tasks of forensic medicine 1. Autopsies in cases of: Ø violent deaths Ø sudden and unexpected deaths Ø "mors in tabula" Ø deaths caused by medical malpractice Ø exhumation.
