1. CA-125 tumor marker
This is a protein measured in blood samples. It is produced by a variety of cells, but particularly by ovarian cancer cells. It is used as a tuomor marker to confirm the suspicion of ovarian cancer and to follow the presence of residual or recurrence of ovarian cancer after surgery. Its blood levels may be elevated in pregnant women and patients with breast and colorectal cancers, endometriosis , ovarian cysts, fibroid s, cirrhosis , hepatitis , or pancreatitis . (Normal range is 0-35 u/mL).

2. Cirrhosis
A disease characterized by the formation of nodules and dense scar tissue in the liver, which may severely impair its function. Cirrhosis may be caused by excessive, long-term consumption of alcohol or by diseases such as hepatitis .

3. Condom
This birth control device is a latex (rubber) sleeve that fits snugly over the penis and is used to prevent pregnancy and sexually transmitted infection s such as AIDS , hepatitis , HPV , gonorrhea , herpes and chlamydia . This method of birth control is easy-to-use and relatively inexpensive. Condoms are especially effective when they are used in conjunction with spermicides (creams or jellies that contain chemicals that kill sperm and some disease-causing microorganisms). When properly used, condoms provide a high rate of protection (96% effectiveness) against pregnancy. Heat (such as from storing a condom in a glove compartment on a hot day) and oil-based lubricants can weaken the rubber in condoms and cause them to break. While the vast majority of condoms are latex, some are made from animal membranes; membrane condoms are not effective in preventing the transmission of diseases because viruses and bacteria can pass through microscopic pores in the membrane.

4. Coronavirus
A genus of pleomorph ic virus es which look like coronas or halos when viewed with a microscope. It is the single genus of the family Coronaviridae. Members of Coronavirus cause hepatitis (inflammation of the liver) in mice, gastroenteritis (inflammation of the digestive system) in pigs, and respiratory infections in birds and people.

5. Delta virus (hepatitis delta virus)
The hepatitis delta virus is a defective virus which uses single-stranded RNA as its genetic material. It is only able to replicate when a helper virus from the family Hepadnaviridae is present in the same host cell . When combined with the virus that causes the disease of hepatitis B , it results in the disease of hepatitis delta .

6. Guillain-Barre Syndrome (acute idiopathic polyneuritis)
A rare disease in which the body's immune system attacks the nerves of the peripheral nervous system , damaging the protective myelin sheath s surrounding the nerves and sometimes damaging the nerve axon s. Symptoms have a range of severity and can include abnormal sensations (such as numbness, pins and needles, vibrations, etc.), muscle weaknesses (due to the destruction of the nerves which carry signals to the affected muscles), aches and pains, and paralysis. The cause of Guillain-Barre Syndrome is unknown; often it is triggered by a virus infection (like hepatitis , mononucleosis , etc.). The disease occurs in both sexes and at any age. Treatment for the disease consists of treating the different symptoms as they arise and rehabilitation. Most patients (around 90%) recover without serious long-term disabilities between six months and two years after the syndrome begins. The 1-5% death rate is usually due to respiratory or cardiovascular complications.

7. HELLP syndrome
HELLP syndrome is characterized by Hemolytic anemia, Elevated Liver enzymes, and Low Platelet count which occurs in about 10% of patients with severe preeclampsia of pregnancy (triad of edema, hypertension, and proteinuria). The abnormal laboratory tests frequently lead to misdiagnosis of hepatitis, gallbladder disease, idiopathic thrombocytopenic purpura, or thrombotic thrombocytopenic purpura.

8. Hepadnaviridae
A family of DNA -containing virus es that infect cause hepatitis in a wide range of vertebrate species.

9. Hepatitis
Inflammation of the liver; symptoms include jaundice (yellowish skin caused by the buildup of bile pigments in the body), fever, appetite loss and gastrointestinal upset. There are several types of viral hepatitis; hepatitis A and B are the most common types, but other versions (C through F) are caused by water-borne calciviruses and togoviruses.

10. Hepatitis A (infectious hepatitis, epidemic jaundice)
A type of hepatitis caused by RNA virus es in the genus Enterovirus in the family Picornaviridae . It is usually fairly mild; people may mistake it for the flu. The virus typically spreads through food or water contaminated with infected feces and is most prevalent in places where people don't practice good hygiene.
