Given the success of drugs to treat erectile dysfunction, such as sildenafil (Viagra), tadalafil (Cialis) and vardenafil (Levitra), drug companies have sought a comparable drug for women. Viagra has even been tried as a treatment for sexual dysfunction in women. However, the Food and Drug Administration (FDA) hasn't approved this use of Viagra. Indeed, until recently there were no FDA-approved drugs for treating sexual arousal or sexual desire problems in women. Yet 4 in 10 women report having sexual concerns. A prescription medication known as flibanserin (Addyi) — originally developed as an antidepressant — has been approved by the FDA as a treatment for low sexual desire in premenopausal women. A daily pill, Addyi may boost sex drive in women with low sexual desire and who find the experience distressing. Potentially serious side effects include low blood pressure, dizziness and fainting, particularly if the drug is mixed with alcohol. Experts recommend that you stop taking the drug if you don't notice an improvement in your sex drive after eight weeks.

Emergency angioplasty is an operation that is performed directly after a heart attack, on admission to the hospital. It involves the insertion of a catheter into the blocked blood vessel that caused the heart attack. This opens it up and allows blood to flow again, thus minimizing damage to the heart.
If one or more arteries become clogged, it may result in a heart attack. This normally presents with chest pain, sweating and a feeling of anxiety, among other symptoms. Urgent medical assistance should be sought. A heart attack is a medical emergency requiring intervention as soon as possible.

What is Osteoporosis

Fibrodysplasia ossificans progressiva (FOP) is a disorder in which muscle tissue and connective tissue such as tendons and ligaments are gradually replaced by bone (ossified), forming bone outside the skeleton (extra-skeletal or heterotopic bone) that constrains movement. This process generally becomes noticeable in early childhood, starting with the neck and shoulders and proceeding down the body and into the limbs. Extra-skeletal bone formation causes progressive loss of mobility as the joints become affected. Inability to fully open the mouth may cause difficulty in speaking and eating. Over time, people with this disorder may experience malnutrition due to their eating problems. They may also have breathing difficulties as a result of extra bone formation around the rib cage that restricts expansion of the lungs.
