Astrocyte Astrocytomas are primary intracranial tumors derived from astrocytes cells of the brain. It is also possible that glial progenitors or neural stem cells give rise to astrocytomas. Astrocytomas are brain tumors that develop from astrocytes. They may occur in many parts of the brain and sometimes in the spinal cord.

Oncovirus An oncovirus is a virus that can cause cancer. This term originated from studies of acutely transforming retroviruses in the 1950–60s, often called oncornaviruses to denote their RNA virus origin. It now refers to any virus with a DNA or RNA genome causing cancer and is synonymous with tumor virus or cancer virus..The vast majority of human and animal viruses do not cause cancer, probably because of longstanding co-evolution between the virus and its host.he theory that cancer could be caused by a virus began with the experiments of Oluf Bang and Vilhelm Ellerman in 1908 who first show that avian erythroblastosis (a form of chicken leukemia) could be transmitted by cell-free extracts.

Actinomycetoma and advances in its treatment Actinomycetoma is a chronic subcutaneous infection caused by aerobic branching actinomycetes. Its clinical features are firm tumefaction of the affected site and the presence of abscesses, nodules, and sinuses that drain a seropurulent exudate containing filamenting granules.

Juvenile Pilocytic Astrocytomas A juvenile pilocytic astrocytoma (JPA) is a slow-growing brain tumor that develops — usually in children and adolescents — from cells called astrocytes. juvenile pilocytic astrocytoma is a cystic (fluid-filled) tumor, not a solid mass. On the World Health Organization’s grading scale, a JPA is a Grade I tumor, highly unlikely to grow or to spread to other areas. Other types of gliomas in children include: 1  Fibrillary astrocytoma.

Plasmacytoma Treatment Plasmacytoma Treatment. A plasmacytoma is a malignant tumor formed by white blood cells. These tumors grow in soft tissue or within bones. Over a 5-10 year period, plasmacytoma that occur in bones can progress to a more serious condition known as multiple myeloma. The majority of cases of plasmacytoma produce a paraprotien that interferes with kidney function. Plasmacytoma that occur in soft tissue are frequently seen in the upper respiratory tract and are very treatable with surgery. Single tumors that are found in bones respond well to radiotherapy.

- Mycoplasma Infection (walking pneumonia, atypical pneumonia)by Dr. Earl H. Eye, M.D. 6/16/98 What is a Mycoplasma infection? Mycoplasma infection is respiratory illness caused by Mycoplasma pneumoniae, a microscopic organism related to bacteria but lacking a cell wall.The organism is larger than a virus but smaller than a bacterium, thus it is called an Atypical bacteria. common result of mycoplasma infection is pneumonia (sometimes called walking pneumonia because it is usually mild and rarely requires hospitalization). Infections of the middle ear (otitis media) also can result. Less common finding are abnormalities of liver function, nausea, diarrhea, and rash.
