Pachymetry is a process by which the thickness of the cornea is measured. It is done by using a medical device called Pachymeter. The process can be carried out by using either optical or ultrasonic methods. There are several uses of pachymetry in the field of ophthalmology.

  • It is an essential process in deciding if laser eye surgery can be safely carried out on a patient. In any type of refractive laser surgery, corneal tissue needs to be removed for re-contouring of the cornea. It helps in deciding whether there is enough corneal tissue for a safe LASIK procedure. Adequate thickness of the cornea helps prevent chances of abnormal corneal bulging, which is a side effect of laser eye surgery known as ectasia.
  • Pachymetry is a significant procedure in detecting early stages of glaucoma and also treating the same. The process aims at measuring the corneal thickness in patients that can impact the intraocular pressure. The measurement is done by using a pachymeter. The course of treatment is determined on the basis of the test results, which usually aims at reducing the intraocular pressure. Though once glaucoma is detected, there is no way it can be cured, it is nevertheless extremely important to have regular eye tests and follow required course of treatments to prevent complete loss of vision.
  • It is also one of the methods for detecting Keratoconus, a condition that results in thinning of the cornea. Keratoconus is often detected before refractive laser surgeries, when it is used for a pre-screening to measure the thickness of the cornea. LASIK procedures are mostly not carried out on a patient with this thinning disease, since it would lead to a further corneal thinning.
  • Pachymetry is a significant method used by doctors to check patients using continuous wear contact lenses for any distortions or steepening of the cornea. According to doctors, the use of pachymeters is on a rise due to an increased use of long-term wear contact lenses in people.

The process can be carried out by practitioners either by ultrasonic or optical methods. Most modern pachymeters use ultrasound technology. The ultrasound method involves giving numbing drops into the eye followed by an immediate application of the pachymeter. The test results are obtained right away. The size of ultrasound pachymeters is almost similar to laptop computers, and hence are extremely portable, enabling them to be easily brought near the patient instead of bringing the patient near the instrument, whenever required.

While optical and ultrasonic pachymetry are just two different ways of carrying out the same process, it is important to know the basic difference between the two. Until recent times, when ultrasound pachymeters came into practice, use of the optical method was the only option available for the doctors.

One of the significant differences between the two methods is that ultrasound pachymeter needs to touch the cornea in order to acquire test results, thereby creating minor compression of the tissue in some cases, and giving a thinner reading compared to an optical pachymeter. Again, ultrasound pachymeters are more portable and delivers results more instantaneously compared to the optical device. However, in some cases comparing the readings obtained from both the methods can help get a more reliable result.

Once a person decides to have breast implants, they need to think very carefully about the size of breasts they want. The decision they make should last for years. The most common reason for re-operations is because the patient didn’t choose the right size in the first place. If the breasts are too large, they may become uncomfortable, and if they are too small, they may not meet the woman’s expectations for breast enhancement.

Each woman has a specific self-image and can imagine her appearance after a breast enhancement procedure, but, above all, she wants her implants to look natural. One way to get a good idea about how different sizes will look is to wear a larger bra and stuff it with small plastic bags of uncooked rice. Several small bags can be made ready to gradually increase the size.

Selecting the correct size usually begins by taking the measurements of the breast base width as well as the soft tissue envelope. This will give the surgeon a good idea of the width limits for the person. Breast implants are measured in cubic centimeters (cc’s). Larger implants have more cc’s. They do not correspond to bra sizes.

The basic factors to consider when determining the right implant size are:

Personal Goals

Whatever goals and expectations a woman has for her appearance after her breast enhancement procedure should be discussed with her surgeon. The surgeon can better understand how to help her achieve her aim. Most women want better self-esteem, better fitting clothing, and improved natural appearance.

You might not be aware of it, but you are using a lot of cancer causing products in your everyday life, and you are not alone.

The average individual is exposed to cancer causing agents, what is known in the scientific community as “carcinogens” through a plethora of factors that may include lifestyle factors, medical treatments, pollution, and other harmful elements that naturally occur in the environment we are part of. While avoiding every form of carcinogen is close to impossible, one could always find effective ways to decrease exposure to a level which would not be a threat to general health.

The Carcinogens You Meet in Everyday Life

Much of the cancer causing products which contribute to higher risks include lifestyle-dependent choices present in the food that we consume or the substances that we ingest. If you are a smoker, then you would know that tobacco is responsible for lung cancer even for the people around you who suffer from second hand smoke. Several studies have also led to declare some specific food groups, even the most common ones like sugar and salt to be carcinogenic. On the contrary, others would depend on the preparation involved, such as charred food, for example.

Carcinogens in the Environment

It should also be noted that the environment is also responsible for many of the carcinogens that could affect our lives. Ultraviolet light, for example, is said to be highly carcinogenic, as well as radon gas and other naturally occurring substances that you just could not avoid. We could also blame the environment for certain medications we ingest in order to battle illnesses acquired though environmental factors, given how certain medications have proven to be carcinogenic in nature as well.

Getting pregnant is either easy or it’s just way too hard – that kind of attitude is very common in our society of quick fixes and extremes. But the truth is that we may not know everything about our bodies and we certainly don’t know everything there is to know about getting pregnant, even if we’ve already had a baby or two. So relax and read on, and you just might pick up a couple of tips to help you get that baby you really want.

1. His Swimmers Are Stubborn. You may have been told to have more sex around ovulation, but the truth is that a man’s sperm can stick around inside you for several days and still remain completely viable. Not only that, but despite all the charts, calendars, apps and cervical mucosa testing, it’s really best practice to have sex every couple of days throughout your cycle. Too time consuming or worried about getting bored? At least focus on the two weeks around your peak of ovulation, i.e. have sex every other day starting one week before you’re meant to ovulate, and keep going a week after as well. If his sperm counts are low, you may want to drop it down to every three or four days, but then you’ll want to extend your window to three weeks.

2. Ditch the Deep-Freeze. Freezing your eggs may not be the best solution if you’re thinking of getting pregnant soon, or even somewhere down the road. It’s usually recommended for people with unavoidable medical concerns and not as a means of extending your fertile years, so bear this in mind. The success rate with frozen eggs drops dramatically as you age, plus there’s really no reason to expect much benefit from the procedure if you’re already in your late 30’s, and it’s quite costly – upwards of $20,000 in some cases. Ask your doctor if you’re interested, but make sure that you get all the facts about your own personal situation.

3. Schedule Your Obsessing. You might become really anxious once you’ve ovulated and you’re simply waiting to see if you’re pregnant or not. While this is completely normal, it won’t leave you feeling very good, and won’t do much for your (hopefully) growing baby. So schedule some time, say 10-15 minutes in the morning and 10-15 minutes at night, each day to make sure you a. get all that obsessing out of the way, and b. you let your mind relax the rest of the day. This focused time for checking charts, mucosa, urine or what have you can leave your mind open to focus on the rest of your life, the rest of the day.

4. Let Your Hair Down. Speaking of stress, relaxing just might be the thing you need to help you conceive. Stress levels can adversely affect your levels of egg-releasing hormones, and so too much stress can cause you to ovulate later than expected, or can even keep it from happening at all. This is one of the ways that acupuncture and Traditional Chinese Medicine, massage therapy, psychotherapy and other natural medicines can help. So if you’ve been having trouble getting pregnant, look at ways that you can help those hormones get a little more balanced.

5. Know the Odds. While it might seem like getting pregnant should be easy – heck, you spent all those years trying NOT to have it happen, so this should just be like letting go, right? If only it were that easy. The truth is that couples in their 30’s only have a 15 percent chance of getting pregnant each month, which is why most doctors suggest giving it a full year before being concerned. Plus, your genetics really determine how many eggs you’re born with, so the fact is that you only have so much control over what happens. Good advice: do your best with what you’ve got (including good nutrition and natural medicine), and leave the rest up to fate.

So, what are the reasons behind swollen taste buds on the tongue? Life-style! The life-style of a person can often provoke the taste buds on the tongue to become inflamed, white (sometimes red in color), and sore, causing a difficulty in eating, and even a loss of appetite – and little to do with telling lies.

What are the taste buds on the tongue responsible for?

Papillae (one of the small protuberances which compose of the senses of smell, touch, and taste), and which distinguish between being bitter or salty, sweet and sour, and umami ([savory, meaty, or brothy] the taste of the food additive MSG [mono-sodium glutamate that is usually found in Chinese foods, snacks, and many seasonings, etc.]).

However, when the taste buds become inflamed, sore, or swollen (for many reasons), not only are they painful as it becomes more difficult to eat, but they also greatly affect the taste of food (food may become diminished in taste).

What are the main causes for the taste buds to become inflamed, white, and sore?

  • Eating overcooked, very hot, very spicy, or acidic (grapefruits, lemons and limes) foods (most common together with cuts on the tongue [also quite common, and usually caused by accidental biting of the tongue]).
  • Smoking (exposure to cigarette smoke [even second-hand smoke]).
  • The ingestion of corrosive chemicals such as: insecticides and certain poisons.
