The A fibers and the C fibers and the Puzzle of Pain

Pain seems like something your gyno should be able to fix, and more often than not, we can. But there are aches and pains that just seem to defy solutions and remain a puzzle. Scientists are trying to figure out why. Start with the concept that pain is the feeling we get when a particular type of nerve fiber sends the brain a signal. A nerve is not just a nerve by any name. While this discussion is of course a gross over simplification, a few important facts have started to emerge. We have Type A-beta fibers, the mediate touch and sensation and we have C fibers, those mediate our perception of noxious stimuli. What triggers the chronic pain, irritation and discomfort of women with vulvodynia seems to be these C fibers getting out of whack. They release cytokines and neurokines to perform their signaling. And with chronic inflammation, product use, treatments, the responses can become inappropriate. So simple touch can give off a pain signal. Makes some sort of sense. In fact it's the type of nerves and the distribution of those nerves that may ultimately be the determining factor in a woman's predisposition to vulvodynia.The solutions can never be found if basic physiology is not understood, so this is a big step forward.

Passing Your Uterine Lining, Menstrual Period Norms

Decidual Cast Periods can be fairly easy, passing some tissue at a time, or off can come the whole lining in one piece called a decidual cast. Generally the lining of the uterus is only 6-8 mm thick at the time of the menstrual period, and it is shed gradually, a few cells at a time. The decidual cast is when the entire lining passes spontaneously. It's not uncommon, but it usually both uncomfortable, and alarming to some. But us women are designed to have some sort of periods Or Not? We have to pass tissue each month. Or Not? Are they good for us? Or Not? Do we want them? Or Not? Is this something that is individual? Or Not? It's a complex topic that I will be discussing a lot over my time in this blog. So lets start with basics: How much do we bleed and what are we loosing, and just what was this that the patient passed? And another basic: track your periods, and the Women's Health Practice site http://www.womenshealthpractice.com/media/pdf/menstrual_chart.pdf you...

Post-Endometrial Ablation Syndrome

If you have had an endometrial ablation and have developed symptoms of pelvic pain you might have post endometrial ablation syndrome. What is post-endometrial ablation syndrome? It is a constellation of symptoms due to entrapped blood or tissue within a uterus that has previously undergone an endometrial ablation. We are able to diagnose this at Women's Health Practic e but occasionally other conditions are causing similar symptoms. Other complications of endometrial ablation include pregnancy, risks from pre-existing conditions such as a polyp or fibroid, an infection of the uterus, or a pregnancy. If you have had a tubal ligation then it is possible that the condition could be post-ablation tubal sterilization syndrome. The ablation procedure is designed to destroy all lining tissue, but in fact there is no way to confirm the completeness of the ablation. It is thought that either residual or regrowth of the tissue is producing the symptoms of post-endometrial ablation syndrom...

You Have an IUD: But a Positive Pregnancy Test

Fortunately IUD pregnancy failures are rare. But if you have an IUD for contraception, and you get a positive pregnancy test, you probably ask yourself, what next? Well, make your gyno appointment promptly, this is a condition that is not typically an emergency, but it can be and it’s not handled over the phone or on a blog, or through self diagnosis! That being said, some researchers from University of Texas Southwestern Medical Center in Dallas decided to look back at over 4100 women who had IUDs and of those 42 cases who became pregnant in their institution, over about a year period of time, to help understand what these women could expect when they got to their gyno and what actually happened to their pregnancies. Accurate pregnancy diagnosis, pelvic examination, and pelvic ultrasound were the cornerstones of the evaluations. They had very specific ways they looked at their ultrasound to prove there was no pregnancy in the fallopian tube, or partially in the fallopian tube...
