Cancer

Malignant Neoplasm is a tumor composed of atypical neoplastic, often pleomorphic cells that invade other tissues. Malignant neoplasms often metastasize to distant anatomic sites and may recur after excision. The most common malignant neoplasms are c... arcinomas (adenocarcinomas or squamous cell carcinomas), Hodgkin and non-Hodgkin lymphomas, leukemias, melanomas, and sarcomas   more

Common cold

The common cold is a viral infectious disease of the upper respiratory tract which primarily affects the nose. Symptoms include coughing, sore throat, runny nose, sneezing, and fever which usually resolve in seven to ten days, with some symptoms las... ting up to three weeks. Well over 200 viruses are implicated in the cause of the common cold; the rhinoviruses are the most common.Upper respiratory tract infections are loosely divided by the areas they affect, with the common cold primarily affecting the nose, the throat, and the sinuses, occasionally involving either or both eyes via conjunctivitis. Symptoms are mostly due to the body's immune response to the infection rather than to tissue destruction by the viruses themselves. The primary method of prevention is by hand washing with some evidence to support the effectiveness of wearing face masks. The common cold may occasionally lead to pneumonia, either viral pneumonia or secondary bacterial pneumonia.No cure for the common cold exists, but the symptoms can be treated. It is the most frequent infectious disease in humans with the average adult contracting two to three colds a year and the average child contracting between six and twelve. These infections have been with humanity since antiquity   more

Asthma

Asthma is a common chronic inflammatory disease of the airways characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm. Common symptoms include wheezing, coughing, chest tightness, and shortness of breath.A... sthma is thought to be caused by a combination of genetic and environmental factors. Its diagnosis is usually based on the pattern of symptoms, response to therapy over time, and spirometry. It is clinically classified according to the frequency of symptoms, forced expiratory volume in one second, and peak expiratory flow rate. Asthma may also be classified as atopic or non-atopic where atopy refers to a predisposition toward developing type 1 hypersensitivity reactions.Treatment of acute symptoms is usually with an inhaled short-acting beta-2 agonist and oral corticosteroids. In very severe cases, intravenous corticosteroids, magnesium sulfate, and hospitalization may be required. Symptoms can be prevented by avoiding triggers, such as allergens and irritants, and by the use of inhaled corticosteroids. Long-acting beta agonists or leukotriene antagonists may be used in addition to inhaled corticosteroids if asthma symptoms remain uncontrolled. The prevalence of asthma has increased significantly since the 1970s. In 2011, 235–300 million people globally have been diagnosed with asthma, and it caused 250,000 deaths   more

Ebola

Ebola virus disease or Ebola hemorrhagic fever is the human disease which may be caused by any of four of the five known ebola viruses. These four viruses are: Bundibugyo virus, Ebola virus, Sudan virus, and Taï Forest virus. EVD is a viral hemorrha... gic fever, and is clinically nearly indistinguishable from Marburg virus disease.The name comes from the Ebola River in the Democratic Republic of the Congo, where it was first found   more

Genital warts

Genital warts are symptoms of a highly contagious sexually transmitted disease caused by some types of human papillomavirus. It is spread through direct skin-to-skin contact, usually during oral, genital, or anal sex with an infected partner. Warts ... are the most easily recognized symptom of genital HPV infection. Although some types of HPV are known to cause cervical cancer and anal cancers, these are not the same types of HPV that cause genital warts. Although 90% of those who contract HPV will not develop genital warts, those infected can still transmit the virus. Although estimates of incidence vary between studies, HPV is so common that nearly all sexually active people will get it at some point in their lives.HPV types 6 and 11 are most frequently the cause of genital warts. The Gardasil vaccine includes coverage for these types. While types 6 and 11 are considered low risk for progression to cancers, it is also possible to be infected with different varieties of HPV, such as a low-risk HPV that causes warts and a high-risk HPV, either at the same or different times   more

AIDS

Acquired Immunodeficiency Syndrome is syndrome resulting from the acquired deficiency of cellular immunity caused by the human immunodeficiency virus (HIV). It is characterized by the reduction of the Helper T-lymphocytes in the peripheral blood a... nd the lymph nodes. Symptoms include generalized lymphadenopathy, fever, weight loss, and chronic diarrhea. Patients with AIDS are especially susceptible to opportunistic infections (usually pneumocystis carinii pneumonia, cytomegalovirus (CMV) infections, tuberculosis, candida infections, and cryptococcosis), and the development of malignant neoplasms (usually non-Hodgkin's lymphoma and Kaposi's sarcoma). The human immunodeficiency virus is transmitted through sexual contact, sharing of contaminated needles, or transfusion of contaminated blood   more

The Flu

Influenza, commonly known as "the flu", is an infectious disease of birds and mammals caused by RNA viruses of the family Orthomyxoviridae, the influenza viruses. The most common symptoms are chills, fever, runny nose, sore throat, muscle pains, hea... dache, coughing, weakness/fatigue and general discomfort. Although it is often confused with other influenza-like illnesses, especially the common cold, influenza is a more severe disease caused by a different type of virus. Influenza may produce nausea and vomiting, particularly in children, but these symptoms are more common in the unrelated gastroenteritis, which is sometimes inaccurately referred to as "stomach flu" or "24-hour flu".Flu can occasionally lead to pneumonia, either direct viral pneumonia or secondary bacterial pneumonia, even for persons who are usually very healthy. In particular it is a warning sign if a child seems to be getting better and then relapses with a high fever as this relapse may be bacterial pneumonia. Another warning sign is if the person starts to have trouble breathing.Typically, influenza is transmitted through the air by coughs or sneezes, creating aerosols containing the virus. Influenza can also be transmitted by direct contact with bird droppings or nasal secretions, or through contact with contaminated surfaces. Airborne aerosols have been thought to cause most infections, although which means of transmission is most important is not absolutely clear. Influenza viruses can be inactivated by sunlight, disinfectants and detergents. As the virus can be inactivated by soap, frequent hand washing reduces the risk of infection   more

Polio

Poliomyelitis, often called polio or infantile paralysis, is an acute, viral, infectious disease spread from person to person, primarily via the fecal-oral route. The term derives from the Greek poliós, meaning "grey", myelós, referring to the grey ... matter of the spinal cord, and the suffix -itis, which denotes inflammation., i.E., inflammation of the spinal cord’s grey matter, although a severe infection can extend into the brainstem and even higher structures, resulting in polioencephalitis, producing apnea that requires mechanical assistance such as an iron lung.Although approximately 90% of polio infections cause no symptoms at all, affected individuals can exhibit a range of symptoms if the virus enters the blood stream. In about 1% of cases, the virus enters the central nervous system, preferentially infecting and destroying motor neurons, leading to muscle weakness and acute flaccid paralysis. Different types of paralysis may occur, depending on the nerves involved. Spinal polio is the most common form, characterized by asymmetric paralysis that most often involves the legs. Bulbar polio leads to weakness of muscles innervated by cranial nerves. Bulbospinal polio is a combination of bulbar and spinal paralysis   more
