Fluconazole
Fluconazole is an antifungal medication used for a number of fungal infections. This includes candidiasis, blastomycosis, coccidiodomycosis, cryptococcosis, histoplasmosis, dermatophytosis, and pityriasis versicolor. It is also used to prevent candidiasis in those who are at high risk such as following organ transplantation, low birth weight babies, and those with neutropenia, low blood neutrophil counts. It is given either by mouth or by intravenous, injection into a vein. Common side effects include vomiting, diarrhea, rash, and elevated transaminases, increased liver enzymes. Serious side effects may include liver problems, QT prolongation, and seizures. During pregnancy it may increase the risk of miscarriage while large doses may cause birth defects. Fluconazole is in the azole antifungal family of medication. It is believed to work by affecting the fungal cellular membrane. Fluconazole was patented in 1981 and came into commercial use in 1988. It is on the WHO Model Lis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Candidiasis
Candidiasis is a fungal infection due to any type of '' Candida'' (a type of yeast). When it affects the mouth, in some countries it is commonly called thrush. Signs and symptoms include white patches on the tongue or other areas of the mouth and throat. Other symptoms may include soreness and problems swallowing. When it affects the vagina, it may be referred to as a yeast infection or thrush. Signs and symptoms include genital itching, burning, and sometimes a white "cottage cheese-like" discharge from the vagina. Yeast infections of the penis are less common and typically present with an itchy rash. Very rarely, yeast infections may become invasive, spreading to other parts of the body. This may result in fevers along with other symptoms depending on the parts involved. More than 20 types of ''Candida'' can cause infection with ''Candida albicans'' being the most common. Infections of the mouth are most common among children less than one month old, the elderly, and those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptococcosis
Cryptococcosis is a potentially fatal fungal infection of mainly the lungs, presenting as a pneumonia, and brain, where it appears as a meningitis. Cough, difficulty breathing, chest pain and fever are seen when the lungs are infected. When the brain is infected, symptoms include headache, fever, neck pain, nausea and vomiting, light sensitivity and confusion or changes in behaviour. It can also affect other parts of the body including skin, where it may appear as several fluid-filled nodules with dead tissue. It is caused by the fungi ''Cryptococcus neoformans'' or less commonly ''Cryptococcus gattii'', and is acquired by breathing in the spores from the air. These fungi are found around the world in soil, decaying wood, pigeon droppings, and in the hollows of some species of trees. Whereas ''C. neoformans'' infects generally people with HIV/AIDS and those on immunosuppressant drugs and does not usually affect fit and healthy people, ''C. gattii'' (found in some parts of Cana ...

Candida Krusei
''Candida krusei'' is a budding yeast (a species of fungus) involved in chocolate production. ''Candida krusei'' is an emerging fungal nosocomial pathogen primarily found in the immunocompromised and those with hematological malignancies. It has natural resistance to fluconazole, a standard antifungal agent. It is most often found in patients who have had prior fluconazole exposure, sparking debate and conflicting evidence as to whether fluconazole should be used prophylactically. Mortality due to ''C. krusei'' fungemia is much higher than the more common ''C. albicans''. Other '' Candida'' species that also fit this profile are ''C. parapsilosis'', ''C. glabrata'', ''C. tropicalis'', ''C. guillermondii'' and ''C. rugosa''. ''Candida krusei'' is the anamorph name; the teleomorph name for the same organism is ''Pichia kudriavzevii.'' The International Commission on the Taxonomy of Fungi (ICTF) and the Nomenclature Committee for Fungi (NCF) have proposed revising the standard na ...

Coccidiodomycosis
Coccidioidomycosis (, ), commonly known as cocci, Valley fever, as well as California fever, desert rheumatism, or San Joaquin Valley fever, is a mammalian mycosis, fungal disease caused by ''Coccidioides immitis'' or ''Coccidioides posadasii''. Coccidioidomycosis is endemic (epidemiology), endemic in certain parts of the United States in Arizona, California, Nevada, New Mexico, Texas, Utah, and northern Mexico. ''C. immitis'' is a Polymorphism (biology), dimorphic saprophytic fungus that grows as a mycelium in the soil and produces a spherule form in the Host (biology), host organism. It resides in the soil in certain parts of the southwestern United States, most notably in California and Arizona. It is also commonly found in northern Mexico, and parts of Central America, Central and South America. ''C. immitis'' is dormant during long dry spells, then develops as a Mold (fungus), mold with long filaments that break off into airborne spores when it rains. The spores, known as a ...

Candida Glabrata
''Candida glabrata'' is a species of haploid yeast of the genus ''Candida'', previously known as ''Torulopsis glabrata''. Despite the fact that no sexual life cycle has been documented for this species, ''C. glabrata'' strains of both mating types are commonly found. C''. glabrata'' is generally a commensal of human mucosal tissues, but in today's era of wider human immunodeficiency from various causes (for example, therapeutic immunomodulation, longer survival with various comorbidities such as diabetes, and HIV infection), ''C. glabrata'' is often the second or third most common cause of candidiasis as an opportunistic pathogen. Infections caused by ''C. glabrata'' can affect the urogenital tract or even cause systemic infections by entrance of the fungal cells in the bloodstream ( Candidemia), especially prevalent in immunocompromised patients. Clinical relevance ''Candida glabrata'' is of special relevance in nosocomial infections due to its innately high resistance to antifu ...

Azole Antifungals
Azoles are a class of five-membered heterocyclic compounds containing a nitrogen atom and at least one other non-carbon atom (i.e. nitrogen, sulfur, or oxygen) as part of the ring. Their names originate from the Hantzsch–Widman nomenclature. The parent compounds are aromatic and have two double bonds; there are successively reduced analogs (azolines and azolidines) with fewer. One, and only one, lone pair of electrons from each heteroatom in the ring is part of the aromatic bonding in an azole. Names of azoles maintain the prefix upon reduction (e.g., pyrazoline, pyrazolidine). The numbering of ring atoms in azoles starts with the heteroatom that is not part of a double bond, and then proceeds towards the other heteroatom. Imidazole and other five-membered aromatic heterocyclic systems with two nitrogens are extremely common in nature and form the core of many biomolecules, such as histidine. Compound classes ;Nitrogen only Imidazol.svg, Imidazole Pyrazol.svg, Pyrazole 1, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neutropenia
Neutropenia is an abnormally low concentration of neutrophils (a type of white blood cell) in the blood. Neutrophils make up the majority of circulating white blood cells and serve as the primary defense against infections by destroying bacteria, bacterial fragments and immunoglobulin-bound viruses in the blood. People with neutropenia are more susceptible to bacterial infections and, without prompt medical attention, the condition may become life-threatening (neutropenic sepsis). Neutropenia can be divided into congenital and acquired, with severe congenital neutropenia (SCN) and cyclic neutropenia (CyN) being autosomal dominant and mostly caused by heterozygous mutations in the ELANE gene (neutrophil elastase). Neutropenia can be acute (temporary) or chronic (long lasting). The term is sometimes used interchangeably with "leukopenia" ("deficit in the number of white blood cells"). Decreased production of neutrophils is associated with deficiencies of vitamin B12 and folic aci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dermatophytosis
Dermatophytosis, also known as ringworm, is a fungal infection of the skin. Typically it results in a red, itchy, scaly, circular rash. Hair loss may occur in the area affected. Symptoms begin four to fourteen days after exposure. Multiple areas can be affected at a given time. About 40 types of fungus can cause ringworm. They are typically of the ''Trichophyton'', ''Microsporum'', or ''Epidermophyton'' type. Risk factors include using public showers, contact sports such as wrestling, excessive sweating, contact with animals, obesity, and poor immune function. Ringworm can spread from other animals or between people. Diagnosis is often based on the appearance and symptoms. It may be confirmed by either culturing or looking at a skin scraping under a microscope. Prevention is by keeping the skin dry, not walking barefoot in public, and not sharing personal items. Treatment is typically with antifungal creams such as clotrimazole or miconazole. If the scalp is involved, anti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Histoplasmosis
Histoplasmosis is a fungal infection caused by ''Histoplasma capsulatum''. Symptoms of this infection vary greatly, but the disease affects primarily the lungs. Occasionally, other organs are affected; called disseminated histoplasmosis, it can be fatal if left untreated. Histoplasmosis is common among AIDS patients because of their suppressed immunity. In immunocompetent individuals, past infection results in partial protection against ill effects if reinfected. ''Histoplasma capsulatum'' is found in soil, often associated with decaying bat guano or bird droppings. Disruption of soil from excavation or construction can release infectious elements that are inhaled and settle into the lung. From 1938 to 2013 in the US, 105 outbreaks were reported in a total of 26 states plus Puerto Rico. In 1978 to 1979 during a large urban outbreak in which 100,000 people were exposed to the fungus in Indianapolis, victims had pericarditis, rheumatological syndromes, esophageal and vocal cord ...

Azole Antifungal
An antifungal medication, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis (thrush), serious systemic infections such as cryptococcal meningitis, and others. Such drugs are usually yes obtained by a doctor's prescription, but a few are available over the counter (OTC). Types of antifungal There are two types of antifungals: local and systemic. Local antifungals are usually administered topically or vaginally, depending on the condition being treated. Systemic antifungals are administered orally or intravenously. Of the clinically employed azole antifungals, only a handful are used systemically. These include ketoconazole, itraconazole, fluconazole, fosfluconazole, voriconazole, posaconazole, and isavuconazole. Examples of non-azole systemic antifungals include griseofulvin and terbinafine.

Blastomycosis
Blastomycosis or blasto is a fungal infection caused by inhaling spores of a ''Blastomyces'' fungus. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired. Symptoms usually develop between three weeks and three months after breathing in the spores. Most blastomycosis infections affect the lungs. In 25 to 40% of cases, the infection also spreads to other parts of the body, such as the skin, bones or central nervous system. Although blastomycosis is especially dangerous for those with weak immune systems, most people diagnosed with blastomycosis have healthy immune systems. ''Blastomyces dermatitidis'' is found in the soil and decaying organic matter like wood or leaves. Outdoor activities like hunting or camping in wooded areas increase the risk of developing blastomycosis. There is no vaccine, but the risk of the disease can be reduced by not disturbing the soil.
