Graying hair is a big concern for both men and women. After age 30 hair begins to gray 10-20% every decade. The process by which hair grays revolves around the presence or absence of a cell type in the hair shaft. The pigment is derived from melanin in cells called melanocytes. These cells are the same cells that produce skin pigment and make us brown or give us olive complexions. When the pigment in the hair shaft dies the hair becomes gray or loses pigment.
Polyps are collections of cells, small clumps within various organs like the nose, the bowel, the ear, the uterus, and the vocal cords. There are essentially two kinds of polyps, pedunculated and sessile. Pedunculat-ed polyps are cells on a stalk like a lollipop. The sessile polyps are flat and part of the tissue on which they arise. Some polyps have cancer producing potential, and this depends on where they are, the size, and the tissue of origin.
Saddle River Residents submitted real medical questions.
This is summer time and the biggest concern we have here in Saddle River is about the huge numbers of deer. They seem to be everywhere, causing accidents, offering themselves up as food for the new crop of coyotes, and causing disease. All deer are carriers of ticks and ticks cause several diseases, the most important one being Lyme disease. I informally took questions from our residents and those of some neighboring towns that also have deer problems.
