Chalazions are extremely common, and having a sound surgical technique to drain a chalazion is a fundamental in general ophthalmology and oculoplastic surgery. I believe one of the biggest downfalls in treating chalazions is inadequate local anesthetic. Please that both the outer and inner surface to the eyelid need to receive local anesthesia to make the patient totally comfortable. It is important to be careful in delivering the local anesthetic and making sure you have control of the head position, and the position of your needle is bent to minimize any possibility of contact with the globe.

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.
Women are routinely invited to have cervical screening tests (also called smear tests). The tests are done to prevent cervical cancer, not to diagnose cancer. During each test some cells are removed from the neck of the womb (cervix), with a plastic brush. The cells are examined under a microscope to look for early changes that, if ignored and not treated, could develop into cancer of the cervix. You are very unlikely to develop cervical cancer if you have regular cervical screening tests at the times advised by your doctor. If the test shows any abnormality, you will have treatment to stop you ever getting cancer of the cervix. So, an abnormal test does not mean you have cancer. It means you should have some treatment to stop you getting cancer.
