Nonfilarial Elephantiasis
Podoconiosis, also known as nonfilarial elephantiasis, is a disease of the lymphatic vessels of the lower extremities that is caused by chronic exposure to irritant soils. It is the second most common cause of elephantiasis, tropical lymphedema after filariasis, lymphatic filariasis, and it is characterized by prominent Swelling (medical), swelling of the lower extremities, which leads to disfigurement and disability. Methods of prevention include wearing shoes and using floor coverings. Mainstays of treatment include daily foot hygiene, compression bandaging, and when warranted, surgery of overlying nodules. Signs and symptoms Podoconiosis causes bilateral yet asymmetrical leg swelling with overlying firm nodules. Early on, symptoms may include itching, tingling, widening of the forefoot, and swelling which then progress to soft edema, skin fibrosis, papillomatosis, and nodule formation resembling moss, giving rise to the disease's alternate name of "mossy foot" in some regions ...

Toxicology
Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants. The relationship between dose and its effects on the exposed organism is of high significance in toxicology. Factors that influence chemical toxicity include the dosage, duration of exposure (whether it is acute or chronic), route of exposure, species, age, sex, and environment. Toxicologists are experts on poisons and poisoning. There is a movement for evidence-based toxicology as part of the larger movement towards evidence-based practices. Toxicology is currently contributing to the field of cancer research, since some toxins can be used as drugs for killing tumor cells. One prime example of this is ribosome-inactivating proteins, tested in the treatment of leukemia. The word ''toxicology'' () is a neocla ...

Neglected Tropical Diseases
Neglected tropical diseases (NTDs) are a diverse group of tropical disease, tropical infections that are common in low-income populations in Developing country, developing regions of Africa, Asia, and the Americas. They are caused by a variety of Pathogen, pathogens, such as viruses, bacteria, protozoa, and parasitic worms (helminths). These diseases are contrasted with the "big three" infectious diseases (HIV/AIDS, tuberculosis, and malaria), which generally receive greater treatment and research funding. In sub-Saharan Africa, disease burden, the effect of neglected tropical diseases as a group is comparable to that of malaria and tuberculosis. NTD co-infection can also make HIV/AIDS and tuberculosis more deadly. Some treatments for NTDs are relatively inexpensive. For example, the treatment for schistosomiasis is US$0.20 per child per year. Nevertheless, in 2010 it was estimated that control of neglected diseases would require funding of between US$2 billion and $3 ...

Macrophage
Macrophages (abbreviated as M φ, MΦ or MP) ( el, large eaters, from Greek ''μακρός'' (') = large, ''φαγεῖν'' (') = to eat) are a type of white blood cell of the immune system that engulfs and digests pathogens, such as cancer cells, microbes, cellular debris, and foreign substances, which do not have proteins that are specific to healthy body cells on their surface. The process is called phagocytosis, which acts to defend the host against infection and injury. These large phagocytes are found in essentially all tissues, where they patrol for potential pathogens by amoeboid movement. They take various forms (with various names) throughout the body (e.g., histiocytes, Kupffer cells, alveolar macrophages, microglia, and others), but all are part of the mononuclear phagocyte system. Besides phagocytosis, they play a critical role in nonspecific defense (innate immunity) and also help initiate specific defense mechanisms (adaptive immunity) by recruiting other immune ...

It shares borders with Eritrea to the north, Djibouti to the northeast, Somalia to the east and northeast, Kenya to the south, South Sudan to the west, and Sudan to the northwest. Ethiopia has a total area of . As of 2022, it is home to around 113.5 million inhabitants, making it the 13th-most populous country in the world and the 2nd-most populous in Africa after Nigeria. The national capital and largest city, Addis Ababa, lies several kilometres west of the East African Rift that splits the country into the African and Somali tectonic plates. Anatomically modern humans emerged from modern-day Ethiopia and set out to the Near East and elsewhere in the Middle Paleolithic period.

Ernest W Price
Dr Ernest Woodward Price MD, FRCSE, DTM&H, OBE (20 July 1907 31 January 1990) was a missionary doctor, orthopaedic surgeon, leprosy specialist and the discoverer of podoconiosis, one of the neglected tropical diseases. A list of his publications is available online. Early life He was born in Sheffield to Baptist missionary parents, Rev. Ernest (born 1874) and Edith Letitia (née Woodward) Price. When he was three years old, the family moved to Kingston, Jamaica, where his father had been appointed headmaster of Calabar High School, a boarding school for the sons of Baptist ministers working in rural areas of Jamaica. Education With his two brothers, Neville Grenville Price born 26 May 1911 (later a teacher) and Bernard Henry Price born 27 January 1913 (later a surgeon), he went to his father's school, Calabar High School.

International Reporting Project
The International Reporting Project, headquartered at New America, funds independent journalistic coverage of under-reported events around the world. The program was created in 1998 as one of the early examples of the non-profit journalism movement, seeking to bridge the gap left by much of the mainstream media's reduction of international news. History of the Project The International Reporting Project (IRP) provides opportunities to journalists to go overseas to do international reporting on critical issues that are under covered in the U.S. news media. The program was created in 1998 by John Schidlovsky, a veteran journalist and former foreign correspondent for The Baltimore Sun in China and India. The program's early founding made it a pioneer in the “non-profit journalism” movement that seeks to fill the gap left by much of the mainstream media’s reduction of international news. The IRP has provided opportunities to more than 600 journalists to travel to more than 110 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mycetoma
Mycetoma is a chronic infection in the skin caused by either bacteria (actinomycetoma) or fungi (eumycetoma), typically resulting in a triad of painless firm skin lumps, the formation of weeping sinuses, and a discharge that contains grains. 80% occur in feet. Most eumycetoma is caused by ''M. mycetomatis'', whereas most actinomycetoma is caused by ''N. brasiliensis'', ''S. somaliensis'', ''A. madurae'' and ''Actinomadura pelletieri''. People who develop mycetoma likely have a weakened immune system. It can take between 3 months to 50 years from time of infection to first seeking healthcare advice. Diagnosis requires ultrasound and fine needle aspiration. While most cases of mycetoma occur in Sudan, Venezuela, Mexico, and India, its true prevalence and incidence are not well-known. It appears most frequently in people living in rural areas, particularly in farmers and shepherds, who are often men between 20 and 40 years earning the primary incomes for their families. It has b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lymphatic Vessel
The lymphatic vessels (or lymph vessels or lymphatics) are thin-walled vessels (tubes), structured like blood vessels, that carry lymph. As part of the lymphatic system, lymph vessels are complementary to the cardiovascular system. Lymph vessels are lined by endothelial cells, and have a thin layer of smooth muscle, and adventitia that binds the lymph vessels to the surrounding tissue. Lymph vessels are devoted to the propulsion of the lymph from the lymph capillaries, which are mainly concerned with the absorption of interstitial fluid from the tissues. Lymph capillaries are slightly bigger than their counterpart capillaries of the vascular system. Lymph vessels that carry lymph to a lymph node are called afferent lymph vessels, and those that carry it from a lymph node are called efferent lymph vessels, from where the lymph may travel to another lymph node, may be returned to a vein, or may travel to a larger lymph duct. Lymph ducts drain the lymph into one of the subclavia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
