Friedrich Fehleisen
Friedrich Fehleisen () (1854–1924) was a German surgeon whose work focused on streptococcal bacteria. Dr. Fehleisen's work played a necessary role in the eventual uncovering of the etiology of many streptococcal illnesses. He made integral contributions to modern medicine's understanding of the ''Streptococcus pyogenes'' organism. He was born in Reutlingen, Württemberg, in 1854, and died in San Francisco, California, in 1924. ''S. pyogenes'' and erysipelas In 1883, he became the first person to culture and collect ''Streptococcus pyogenes'', which causes scarlet fever and other streptococcal illnesses. He cultured it from perierysipelas lesions on humans. One year later, the organism received its current name from Rosenbach. German physician Friedrich Loeffler subsequently demonstrated the presence of streptococci in the throats of patients with scarlet fever. Additionally, Dr. Fehleisen uncovered the etiology of erysipelas, which is an acute streptococcal bacterial infectio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etiology
Etiology (pronounced ; alternatively: aetiology or ætiology) is the study of causation or origination. The word is derived from the Greek (''aitiología'') "giving a reason for" (, ''aitía'', "cause"); and ('' -logía''). More completely, etiology is the study of the causes, origins, or reasons behind the way that things are, or the way they function, or it can refer to the causes themselves. The word is commonly used in medicine (pertaining to causes of disease) and in philosophy, but also in physics, psychology, government, geography, spatial analysis, theology, and biology, in reference to the causes or origins of various phenomena. In the past, when many physical phenomena were not well understood or when histories were not recorded, myths often arose to provide etiologies. Thus, an etiological myth, or origin myth, is a myth that has arisen, been told over time or written to explain the origins of various social or natural phenomena. For example, Virgil's ''Aeneid'' is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Friedrich Loeffler
Friedrich August Johannes Loeffler (; 24 June 18529 April 1915) was a German bacteriologist at the University of Greifswald. Biography He obtained his M.D. degree from the University of Berlin in 1874. He worked with Robert Koch from 1879 to 1884Isaac Asimov, ''Asimov's Biographical Encyclopedia of Science and Technology'', 2nd Revised edition as an assistant in the Imperial Health Office in Berlin. In 1884, he became staff physician at the Friedrich Wilhelm Institute in Berlin, and four years later became professor at the University of Greifswald. His development of original methods of staining rendered an important and lasting service to bacteriology. Early in his career, he began a study of parasitic diseases. Among his discoveries was the organism causing diphtheria (''Corynebacterium diphtheriae'') and the cause of foot-and-mouth disease (Aphthovirus). His description of the diphtheria bacillus, published in 1884, was the originating cause of an antitoxin treatment. He also c ...

Coley's Toxins
Coley's toxins (also called Coley's toxin, Coley's vaccine, Coley vaccine, Coley's fluid or mixed bacterial vaccine) is a mixture containing toxins filtered from killed bacteria of species ''Streptococcus pyogenes'' and ''Serratia marcescens'', named after William Coley, a surgical oncologist at the Hospital for Special Surgery who developed the mixture in the late 19th century as a treatment for cancer. Their use in the late nineteenth and early 20th centuries represented a precursor to modern immunotherapy, although at that time their mechanism of action was not completely understood. Many important aspects of the mechanisms of action, such as that involving T-cells and NK cells, have been more recently identified. The FDA-approved BCG for non-muscle invasive bladder cancer is a highly related strategy of Coley's Toxin. History Bacterial immunotherapy for the treatment of cancer has been utilized throughout history, with the earliest cases going back to c 2600 BC. Egyptian ...

William Coley
William Bradley Coley (January 12, 1862 – April 16, 1936) was an American bone surgeon and cancer researcher best known for his early contributions to the study of cancer immunotherapy. Although his work was not proven effective in his lifetime, modern discoveries and research in immunology have led to a greater appreciation for his work in cancer immunotherapy and his targeted therapy, Coley's toxins. Today, Coley is recognized as the ''Father of Cancer Immunotherapy'' for his contributions to the science. Early life and career Education William Coley was born on January 12, 1862, in Saugatuck, a neighborhood of Westport, Connecticut. His parents were Horace Bradley Coley and Clarina B. Wakeman. He received his bachelor's degree in Classics from Yale University and his medical degree from Harvard Medical School in 1888. After his schooling, Coley began working at New York Hospital, now Weill Cornell Medical Center, as a surgical intern. Early sarcoma patients In 1890, Coley b ...

Fibrosarcoma
Fibrosarcoma (fibroblastic sarcoma) is a malignant mesenchymal tumour derived from fibrous connective tissue and characterized by the presence of immature proliferating fibroblasts or undifferentiated anaplastic spindle cells in a storiform pattern. Fibrosarcomas mainly arise in people between the ages of 25–79 It originates in fibrous tissues of the bone and invades long or flat bones such as the femur, tibia, and mandible. It also involves the periosteum and overlying muscle. Presentation Adult-type Individuals presenting with fibrosarcoma are usually adults thirty to fifty-five years old, often presenting with pain. Among adults, fibrosarcomas develop equally in men and women. Infantile-type In infants, fibrosarcoma (often termed congenital infantile fibrosarcoma) is usually congenital. Infants presenting with this fibrosarcoma usually do so in the first two years of their life. Cytogenetically, congenital infantile fibrosarcoma is characterized by the majority of cases ...

Lymphatic System
The lymphatic system, or lymphoid system, is an organ system in vertebrates that is part of the immune system, and complementary to the circulatory system. It consists of a large network of lymphatic vessels, lymph nodes, lymphatic or lymphoid organs, and lymphoid tissues. The vessels carry a clear fluid called lymph (the Latin word ''lympha'' refers to the deity of fresh water, "Lympha") back towards the heart, for re-circulation. Unlike the circulatory system that is a closed system, the lymphatic system is open. The human circulatory system processes an average of 20 litres of blood per day through capillary filtration, which removes plasma from the blood. Roughly 17 litres of the filtered blood is reabsorbed directly into the blood vessels, while the remaining three litres are left in the interstitial fluid. One of the main functions of the lymphatic system is to provide an accessory return route to the blood for the surplus three litres. The other main function is that of ...

Dermis
The dermis or corium is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain. It is divided into two layers, the superficial area adjacent to the epidermis called the papillary region and a deep thicker area known as the reticular dermis.James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology'' (10th ed.). Saunders. Pages 1, 11–12. . The dermis is tightly connected to the epidermis through a basement membrane. Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix.Marks, James G; Miller, Jeffery (2006). ''Lookingbill and Marks' Principles of Dermatology'' (4th ed.). Elsevier Inc. Page 8–9. . It also contains mechanoreceptors that provide the sense of touch and thermoreceptors that provide the sense of heat. In addition, hair follicles, ...

Modern Medicine
Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of skill and knowledge), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, or an ancie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
