The field of medicine that pertains to helminths (worms) capable of disease in people. For more about these worms, see “Helminth.”
The public health impact of medical helminths is appreciable. Two billion people are infected by soil-transmitted helminths such as Ascaris, hookworms, and Trichuris trichiura and by schistosomes. Early childhood infections by soil-transmitted helminths delays physical and cognitive development. Other widespread helminthic infections include onchocerciasis, lymphatic filariasis, dracunculiasis (Guinea worm disease), and food-borne trematode and tapeworm infections. All of these infections cause chronic morbidity and debilitation.
Medical helminths need to develop in a parasitized host, and sometimes this involves several disparate hosts. Helminth parasites are more complex than free-living helminths, because they have evolved mechanisms to deal with the different environments of their various hosts and living conditions. They have developed host-finding behaviors, exquisite migration patterns within each host, and the ability to evade the host immune and protective responses.
- Medical history
1. In clinical medicine, the patient’s past and present which may contain relevant information bearing on their health past, present, and future. The medical history, being an account of all medical events and problems a person has experienced is an important tool in the management of the patient. 2. The history of medicine.

the “Philosophical Transactions of the Royal Society.” The other was the “Journal des Scavants” (Scholars) which appeared in France the same year. From these 2 journals are descended the many thousands of scientific periodicals today, including all those devoted to the biomedical sciences and medicine, whether they be in print or newer media such as […]
- Medical jurisprudence
The branch of the law that deals with the application of law to medicine or, conversely, the application of medical science to legal problems. Medical jurisprudence may be involved in cases concerning genetic relationships (eg, paternity testing) or injury or death resulting from violence. An autopsy may be done to help determine the agent of […]

“For decades, ionizing radiation has been beneficial to human beings in areas ranging from medical diagnosis and therapy to scientific research to generating electrical power. However, when used in large quantities or in unsafe ways, ionizing radiation can harm living organisms. Care must be taken to properly use equipment and to minimize the potential for […]
