Information for Patients


Anal Disorders

Also called: Anorectal diseases

The anus is the opening of the rectum through which stool passes out of your body. Problems with the anus are common. They include hemorrhoids, abscesses, fissures (cracks), and cancer.

You may be embarrassed to talk about your anal troubles. But it is important to let your doctor know, especially if you have pain or bleeding. The more details you can give about your problem, the better your doctor will be able to help you. Treatments vary depending on the particular problem.

Syphilis

Syphilis is a sexually transmitted disease caused by bacteria. It infects the genital area, lips, mouth, or anus of both men and women. You usually get syphilis from sexual contact with someone who has it. It can also pass from mother to baby during pregnancy.

The early stage of syphilis usually causes a single, small, painless sore. Sometimes it causes swelling in nearby lymph nodes. If you do not treat it, syphilis usually causes a non-itchy skin rash, often on your hands and feet. Many people do not notice symptoms for years. Symptoms can go away and come back.

The sores caused by syphilis make it easier to get or give someone HIV during sex. If you are pregnant, syphilis can cause birth defects, or you could lose your baby. In rare cases, syphilis causes serious health problems and even death.

Syphilis is easy to cure with antibiotics if you catch it early. Correct usage of latex condoms greatly reduces, but does not completely eliminate, the risk of catching or spreading syphilis.
