Timeline Of AIDS
This is a timeline of HIV/AIDS, including cases before 1980. Pre-1980s Researchers estimate that some time in the early 20th century, a form of Simian immunodeficiency virus found in chimpanzees (SIVcpz) first entered humans in Central Africa and began circulating in Léopoldville (modern-day Kinshasa) by the 1920s. This gave rise to the pandemic form of HIV (HIV-1 group M); other zoonotic transmissions led to the other, less prevalent, subtypes of HIV. ; ;1930s to 1950s * A range of small scale ''Pneumocystis'' pneumonia epidemics occurred in northern and central European countries between the 1930s and 1950s, affecting children who were prematurely born. The epidemics spread likely due to infected glass syringes and needles. Malnutrition was not considered a cause, especially because the epidemics were at their height in the 1950s. At that time war torn Europe had already recovered from devastation. Researchers state that the most likely cause was a retrovirus closely related ...

HIV/AIDS
Human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV), a retrovirus. Following initial infection an individual may not notice any symptoms, or may experience a brief period of influenza-like illness. Typically, this is followed by a prolonged incubation period with no symptoms. If the infection progresses, it interferes more with the immune system, increasing the risk of developing common infections such as tuberculosis, as well as other opportunistic infections, and tumors which are rare in people who have normal immune function. These late symptoms of infection are referred to as acquired immunodeficiency syndrome (AIDS). This stage is often also associated with unintended weight loss. HIV is spread primarily by unprotected sex (including anal and vaginal sex), contaminated blood transfusions, hypodermic needles, and from mother to ch ...

Femoral Hernia
Femoral hernias occur just below the inguinal ligament, when abdominal contents pass through a naturally occurring weakness in the abdominal wall called the femoral canal. Femoral hernias are a relatively uncommon type, accounting for only 3% of all hernias. While femoral hernias can occur in both males and females, almost all develop in women due to the increased width of the female pelvis. Femoral hernias are more common in adults than in children. Those that do occur in children are more likely to be associated with a connective tissue disorder or with conditions that increase intra-abdominal pressure. Seventy percent of pediatric cases of femoral hernias occur in infants under the age of one. Definitions A hernia is caused by the protrusion of a viscus (in the case of groin hernias, an intra-abdominal organ) through a weakness in the abdominal wall. This weakness may be inherent, as in the case of inguinal, femoral and umbilical hernias. On the other hand, the weakness ma ...

Cryptococcus Neoformans
''Cryptococcus neoformans'' is an encapsulated yeast belonging to the class Tremellomycetes and an obligate aerobe that can live in both plants and animals. Its teleomorph is a filamentous fungus, formerly referred to ''Filobasidiella neoformans''. In its yeast state, it is often found in bird excrement. ''Cryptococcus neoformans'' can cause disease in apparently immunocompetent, as well as immunocompromised, hosts. Classification ''Cryptococcus neoformans'' has undergone numerous nomenclature revisions since its first description in 1895. It formerly contained two varieties: ''C. neoformans ''var.'' neoformans'' and ''C. neoformans '' var.'' grubii''. A third variety, ''C. neoformans ''var.'' gattii'', was later defined as a distinct species, ''Cryptococcus gattii''. The most recent classification system divides these varieties into seven species. ''C. neoformans'' refers to ''C. neoformans '' var.'' grubii''. A new species name, ''Cryptococcus deneoformans'', is used for the f ...

Fungal Meningitis
Fungal meningitis refers to meningitis caused by a fungal infection. Signs and symptoms Symptoms of fungal meningitis are generally similar to those of other types of meningitis, and include: a fever, stiff neck, severe headache, photophobia (sensitivity to light), nausea and vomiting, and altered mental status (drowsiness or confusion). Causes Fungal meningitis may be caused by the following (and also other) types of fungi: * ''Candida'' - ''C. albicans'' is the most common ''Candida'' species that causes infections of the central nervous system. * ''Coccidioides'' - it is endemic to southwestern United States and Mexico. A third of patients presenting with disseminated coccidioidomycosis have developed meningitis. * ''Histoplasma'' - occurs in bird and bat droppings and is endemic to parts of the United States, South, and Central America. Involvement of the central nervous system occurs in about 10-20% of cases of disseminated histoplasmosis. * ''Blastomyces'' - occurs in ...

Lake Tanganyika
Lake Tanganyika () is an African Great Lake. It is the second-oldest freshwater lake in the world, the second-largest by volume, and the second-deepest, in all cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. The lake is shared among four countries—Tanzania, the Democratic Republic of the Congo (DRC), Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean. Etymology "Tanganika" was the name of the lake that Henry Morton Stanley encountered when he was at Ujiji in 1876. The name first originated from the Bembe language when they arrived in South Kivu around the 7th century, they discovered the lake and started calling it “êtanga ‘ya’ni’â” which means “a big river” in their Bantu language. Stanley found also other names for the lake among different ethnic groups, like the Kimana, the Yemba and the Msaga. An alt ...

Mount Sinai Medical Center
Mount Sinai Hospital, formerly at times known as Mount Sinai Medical Center, is a 319-bed major urban hospital in Chicago, Illinois, with its main campus located adjacent to Douglass Park at 15th Street and California Avenue on the city's West Side. The hospital was established in 1912 under the name Maimonides Hospital, with a mission of serving poor immigrants from Europe while providing training to Jewish physicians, primarily of Eastern European descent. After a period of financial difficulty, it closed in 1918, and was reopened as "Mount Sinai Hospital" in 1919, with 60 beds and continuing its original mission. History The second Jewish hospital to be established in the city, Mount Sinai Hospital differed from Michael Reese Hospital, which had been established in 1881 on Chicago's South Side primarily by German Jews, whereas Mount Sinai was founded by Eastern European Jews. Unlike other hospitals, Mount Sinai had a kosher (also or , ) is a set of dietary laws dealing ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cytomegalovirus
''Cytomegalovirus'' (''CMV'') (from ''cyto-'' 'cell' via Greek - 'container' + 'big, megalo-' + -''virus'' via Latin 'poison') is a genus of viruses in the order ''Herpesvirales'', in the family ''Herpesviridae'', in the subfamily ''Betaherpesvirinae''. Humans and other primates serve as natural hosts. The 11 species in this genus include ''human betaherpesvirus 5'' (HCMV, human cytomegalovirus, HHV-5), which is the species that infects humans. Diseases associated with HHV-5 include mononucleosis and pneumonia, and congenital CMV in infants can lead to deafness and ambulatory problems. In the medical literature, most mentions of CMV without further specification refer implicitly to human CMV. Human CMV is the most studied of all cytomegaloviruses. MX2/MXB protein was identified as a restriction factor for herpesviruses, which acts at a very early stage of the replication cycle and MX2/MXB restriction of herpesvirus requires GTPase activity. Taxonomy Within the ''Herpesvi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Silver Lake, Los Angeles
Silver Lake is a residential and commercial neighborhood in the east-central region of Los Angeles, California. Originally home to a small community called Ivanhoe in honor of Sir Walter Scott. In 1907, the Los Angeles Water Department built the Silver Lake Reservoir, named for LA Water Commissioner Herman Silver, giving the neighborhood its name. The area is now known for its architecturally significant homes, independently owned businesses, diverse restaurants, painted staircases, and a creative environment. The neighborhood is also home to several highly rated public and private schools. Geography and climate Silver Lake is flanked on the northeast by Atwater Village and Elysian Valley, on the southeast by Echo Park, on the southwest by Westlake, on the west by East Hollywood and on the northwest by Los Feliz.

Gaëtan Dugas
Gaëtan Dugas (; February 19, 1952 – March 30, 1984) was a Québécois Canadian flight attendant and a relatively early HIV patient who once was widely regarded as "Patient Zero," or the primary case for AIDS in the United States. This claim was later found to be incorrect. In March 1984, a Centers for Disease Control and Prevention (CDC) study tracked the sexual liaisons and practices of gay and bisexual men, especially in California and New York. Dugas was code-named "Patient O" (meaning out of state) to indicate his role in a cluster of 40 AIDS cases in the United States. This was misinterpreted as "Patient Zero" and media later extrapolated this information to mean that he was the original carrier of AIDS in the country, although the report itself made no such claim. After a new genetic analysis of stored blood samples, bolstered by some historical detective work, scientists declared that he did not bring HIV to the United States and was not Patient Zero.

Grethe Rask
Margrethe P. Rask (1930 – 12 December 1977), better known as Grethe Rask, was a Danish physician and surgeon in Zaïre (now the Democratic Republic of the Congo). After setting up her own hospital in the village of Abumombazi in 1972, she transferred to Danish Red Cross Hospital in Kinshasa in 1975. She returned to Denmark in 1977 after developing symptoms of an unknown infectious disease, which was later discovered to be AIDS. Three and a half years later in June 1981 the Centers for Disease Control recognized AIDS. Rask was one of the first non-Africans (along with Arvid Noe and Robert Rayford) and first non-men who have sex with men known to have died of AIDS-related causes. Early years and Zaïre (1930–1974) Born in 1930 in the Danish town of Thisted, Rask practiced medicine in Zaïre for a brief period in 1964, when she was recalled to Europe for training in stomach surgery and tropical illnesses, from 1972 to 1977, first at a small local hospital in the Zairian tow ...

Arvid Noe
Arne Vidar Røed (23 July 1946 – 24 April 1976), known in medical literature by the anagram Arvid Darre Noe, was a Norwegian sailor and truck driver who contracted one of the earliest confirmed cases of HIV/AIDS. His was the first confirmed HIV case in Europe though the disease was not identified at the time of his death. The virus spread to his wife and youngest daughter both of whom also died; this was the first documented cluster of AIDS cases before the AIDS epidemic of the early 1980s. The researchers studying the cases referred to Røed as the "Norwegian sailor" or the anagram "Arvid Darre Noe" to conceal his identity; his true name, Arne Vidar Røed, became known long after his death. Illness and death Roed began his career in the merchant navy in 1961, at the age of 15. As established by the journalist Edward Hooper, Roed visited Africa twice during his travels; the first time from 1961 to 1962 on board the ''Hoegh Aronde'', along the west coast of Africa to Douala, ...

Robert Rayford
Robert Lee Rayford (February 3, 1953 – May 15 1969), sometimes identified as Robert R. due to his age, was an American teenager from Missouri who has been suggested to represent the earliest confirmed case of HIV/AIDS in North America based on evidence which was published in 1988 in which the authors claimed that medical evidence indicated that he was "infected with a virus closely related or identical to human immunodeficiency virus type 1." Rayford died of pneumonia, but his other symptoms baffled the doctors who treated him. A study published in 1988 reported the detection of antibodies against HIV. Results of testing for HIV genetic material were reported once at a scientific conference in Australia in 1999; however, the data has never been published in a peer-reviewed medical or scientific journal. Background Robert Rayford was born on February 3, 1953, in St. Louis, Missouri to Constance Rayford (September 12, 1931 – April 3, 2011) and Joseph Benny Bell (March 24, ...
