Rubber band ligation is a procedure in which the hemorrhoid is tied off at its base with rubber bands, cutting off the blood flow to the hemorrhoid. This treatment is only for internal hemorrhoids. To do this procedure, a doctor inserts a viewing instrument (anoscope) into the anus. The hemorrhoid is grasped with an instrument, and a device places a rubber band around the base of the hemorrhoid. The hemorrhoid then shrinks and dies and, in about a week, falls off. A scar will form in place of the hemorrhoid, holding nearby veins so they don't bulge into the anal canal. The procedure is done in a doctor's office. You will be asked whether the rubber bands feel too tight. If the bands are extremely painful, a medicine may be injected into the banded hemorrhoids to numb them. After the procedure, you may feel pain and have a sensation of fullness in the lower abdomen. Or you may feel as if you need to have a bowel movement. Treatment is limited to 1 to 2 hemorrhoids at a time if done in the doctor's office. Several hemorrhoids may be treated at one time if the person has general anesthesia. Additional areas may be treated at 4- to 6-week intervals.

A spermatocelectomy is surgery to remove a spermatocele. A spermatocele is a cyst (sac of fluid) that contains sperm. It forms inside your scrotum on the outside of your testicle. The cyst is most often attached to your epididymis. The epididymis is a tube that stores sperm.

More than three decades on from its first outbreak, HIV/AIDS remains a prevalent killer, even in the developed world, and a pressing scientific challenge to understand and treat. The rate of infection, especially among young people, is increasing, and in parts of Africa in particular, it remains an epidemic-scale killer. Yet a cure could be just around the corner, and scientists are optimistic that the virus’ days might be numbered. Is HIV here to stay, or will it be consigned to history like Smallpox? Produced by ABC Australia - Ref-6621 Journeyman Pictures brings you highlights from the cutting-edge science series, ‘Catalyst’, produced by our long-term content partners at ABC Australia. Every day we’ll upload a new episode that takes you to the heart of the most intriguing and relevant science-related stories of the day, transforming your perspective of the issues shaping our world.

Calcium channel blockers prevent calcium from entering cells of the heart and blood vessel walls, resulting in lower blood pressure. Calcium channel blockers, also called calcium antagonists, relax and widen blood vessels by affecting the muscle cells in the arterial walls. Some calcium channel blockers have the added benefit of slowing your heart rate, which can further reduce blood pressure, relieve chest pain (angina) and control an irregular heartbeat. Examples of calcium channel blockers Some calcium channel blockers are available in short-acting and long-acting forms. Short-acting medications work quickly, but their effects last only a few hours. Long-acting medications are slowly released to provide a longer lasting effect. Several calcium channel blockers are available. Which one is best for you depends on your health and the condition being treated. Examples of calcium channel blockers include: Amlodipine (Norvasc) Diltiazem (Cardizem, Tiazac, others) Felodipine Isradipine Nicardipine Nifedipine (Adalat CC, Afeditab CR, Procardia) Nisoldipine (Sular) Verapamil (Calan, Verelan) In some cases, your doctor might prescribe a calcium channel blocker with other high blood pressure medications or with cholesterol-lowering drugs such as statins.

Pectus excavatum (hollow chest) deformity is not uncommon (sometimes mild and other times severe in its form). The chest deformity is often the source of self-consciousness for the patients while growing up. Several surgical techniques (Nuss procedure, Ravitch procedure, etc) are available.

A voice prosthesis (plural prostheses) is an artificial device, usually made of silicone that is used to help laryngectomized patients to speak. During a total laryngectomy, the entire voice box (larynx) is removed and the windpipe (trachea) and food pipe (esophagus) are separated from each other.

A prenatal ultrasound (also called a sonogram) is a noninvasive diagnostic test that uses sound waves to create a visual image of your baby, placenta, and uterus, as well as other pelvic organs. It allows your healthcare practitioner to gather valuable information about the progress of your pregnancy and your baby's health. During the test, an ultrasound technician (sonographer) transmits high-frequency sound waves through your uterus that bounce off your baby. A computer then translates the echoing sounds into video images that reveal your baby's shape, position, and movements. (Ultrasound waves are also used in the handheld instrument called a Doppler that your practitioner uses during your prenatal visits to listen to your baby's heartbeat.) You may have an early ultrasound at your practitioner's office at 6 to 10 weeks to confirm and date the pregnancy. Or you may not have one until the standard midpregnancy ultrasound between 16 and 20 weeks. That's when you may learn your baby's sex, if you like. (The technician will probably present you with a grainy printout of the sonogram as a keepsake.) You may also have a sonogram as part of a genetic test, such as the nuchal translucency test, chorionic villus sampling, or amniocentesis, or at any other time if there are signs of a problem with your baby. You'll have more frequent ultrasounds if you have diabetes, hypertension, or other medical complications.
