You have to do some thinking. (Everything is physics!) Maybe these questions might start you off:
Do any medical instruments magnify things? (lenses)
Do any medical instruments examine things? (ultrasound, Xrays)
Do any medical instruments suck up fluid? (pressure)
Do any medical instruments cut things? (pressure)
Do any medical instuments exert pull things? (forces)
Do you get the idea?

Prior to a decade ago, it was rare for medical personnel to perform abortions on patients 6 weeks or less. Reasons for this are the increased chance of retained (left behind) tissue because the pregnancy sac was so small it was easier to miss. This can lead to uterine infection, and heavy vaginal bleeding. There are times when the entire pregnancy is missed when there is the attempt to perform surgical procedures on patients that are less than 6 weeks from their last period. Other complications that occur are a higher risk for cervical (lower womb) tears, difficult dilation (opening) of the cervix, and uterine perforation (a hole or tear) which can lead to infection, bleeding, hysterectomy (surgical removal of the uterus, or even death of the patient.

There has been a great demand from women to have their abortion procedures carried out earlier for several reasons. Some of them are: 1) reduction in pregnancy symptoms which include nausea, vomiting, breast tenderness, swelling, weight gain or loss, dizziness, headaches and fatigue. These symptoms can lead to a significant loss of school, work, and other activities that a women are required to do on a daily basis. 2) moral and ethical reasons where the less developed the pregnancy, the less guilt there is regarding the abortion procedure and 3) there is a faster recovery time and one can generally resume their normal activities the same day and may engage in sexual intercourse 24 hours after the procedure is performed if less than 6 weeks pregnant. 4) bleeding only lasts for 2 to 3 days. 5) one may take a bath after 24 hours instead of waiting for at least 2 weeks when over 6 weeks pregnant.

With the advancement of medical equipment, medications, instruments and training, performing early surgical abortions are performed throughout the U.S. and the world by specially trained Physicians in this area. Performing sonograms (ultrasound) and visualizing the small gestational sac (pregnancy) inside the uterus is crucial. A pregnancy cannot be seen until 3 to 4 weeks within the uterus. One then needs to determine whether the cervix needs to be primed (soft and easy to dilate) by either giving medication that causes contractions of the uterus, or by inserting a piece of sterile seaweed inside the cervix that causes it to dilate. This helps reduce the chance of cervical tears, uterine rupture, or retained pregnancy tissue while performing the procedure. Performing an ultrasound while simultaneously carrying out the termination procedure can help reduce the chance of retained tissue or uterine rupture.

The surgical procedure at less than 6 weeks consists of placing a speculum (used for Pap Smear) inside the vagina and then numbing the cervix using lidocaine followed by dilating (opening) the cervix and placing a small sterile catheter (smaller than a straw) inside the uterus and removing the pregnancy. There is cramping involved that lasts from 10 to 15 minutes. Bleeding usually lasts from 3 to 4 days. For most patients, IV sedation is not required but it is available if the patient requests.

In conclusion; with medical advances, early surgical abortion procedures are in high demand, and can now be carried out around the time of the patient's first missed period (4 weeks) efficiently, with minimal complications, and the majority of patients return back to their routine activities the same day.

Either one has the potential to be stressful. Doctors/surgeons are some of the most narcissistic people on earth and are very hard to work for. I think you'll make more and be happier in a dental office.

Teeth are supported and surrounded by tissues. Mouth is a well developed breeding ground for bacteria and thereby infection.

Gums are also great breeding grounds for harmful bacteria. Problem arises when gums are attacked by harmful bacteria, resulting in severe infection. This type of infection is termed as Periodontitis. It is actually, inflation of gums. When neglected, Periodontitis may lead to Gingivitis, a much severe gum disease.

Gum diseases start when teeth are not cleaned properly after every meal. This leads to formation of yellow covering on a tooth that hardens into tartar in due course of time. Tartar can be cleaned only under strict medical supervision.

Periodontal disease is related to infection of tissues and bones surrounding the tooth. If left untreated, then it results in loss of tooth, due to loosening of tooth inside the surrounding infected tissues.

Initial Periodontitis is low grade in infection where good quality tooth brush with regular cleaning will also not provide necessary relief. The amount of tartar formed around the tooth is much more then desired level. The bacteria in calulus start producing toxins and harmful sulphur compounds to destroy bone structure and subsequently gums around the tooth. Sulphur compounds also produce bad breath inside the mouth. Periodontal pocket bacteria make a reservoir in this pocket (space between tooth and gums) causing further infections.

When the space between tooth and gums reaches up to a depth of 5mm, this is termed as Modest Periodontitis Disease.

The next worst stage is Extreme Periodontitis where pockets between gums and tooth get further deep to reach 6mm depth. In this case, the only treatment is surgery.

Surgical treatment means removal of infected or diseased tissues. Dentists clean the structure thoroughly, so that it is no longer a breeding ground for plaque or tartar.

In extreme Periodontitis, bone structure is also infected, and then bone grafting is only solution. Untreated tooth will lead to loss of tooth due to destruction of supporting bone. The process is very gradual but created deep impact in mouth. Therefore it needs immediate attention.

Precaution is better than cure. Therefore take proper care of your teeth to prevent Periodontitis Disease.

Ultrasonic Cleaners: The Versatile And Thorough Way To Keep Lab Equipment Clean

Scientific and Laboratory Ultrasonic Cleaners An ultrasonic cleaner in your laboratory will save time and reduce effort while providing a safe solution for your cleaning needs. Let's take a look at some considerations you should keep in mind when using an ultrasonic cleaner on glassware, plasticware, and your lab instruments.

Whether you are cleaning beakers, bottles, vials, pipettes, or other labware, laboratory ultrasonic cleaners eliminate the time and effort of manual scrubbing. In fact, studies have shown that it can be up to 60 times faster while delivering thoroughly clean results. In addition, ultrasonic cleaning reaches into crevices and small openings that can’t be cleaned manually. Cleanliness of laboratory vessels and instruments is critical, as any residue from a prior laboratory procedure may contaminate the next experiment, test, or process.

Always wash glassware immediately after use.  If this is not possible, allow the glassware to soak. There is a possibility that if the glass is not cleaned immediately some residues will be impossible to remove. Never soak for long periods in alkaline solutions, as this will damage the glass. When using an ultrasonic cleaner, place the glassware in a basket so that the objects do not come in contact with the bottom of the tank, the vibrating ultrasonic membrane. After the ultrasonic labware cleaning stage is finished, rinse with distilled or deionized water rather than tap water. This will ensure that your items will dry completely and without spots. Finally, inspect the glassware to ensure that there are no cracks or chips, as this can affect future tests and samples.

Certain types of cleaning chemicals such as highly alkaline detergents can lead to clouding, crazing or stress cracking of plasticware, particularly polycarbonate. Long periods of exposure to strong oxidising agents are also known to cause plasticware to become brittle and prone to failure. For this reason, you should not use strong cleaning agents on plasticware. You should also never use abrasive cleaners or scouring pads which scratch the surface of plasticware. For ultrasonic cleaning lab plasticware, the same rules apply as glassware. Make sure to place the items in a basket to ensure they do not touch the ultrasonic membrane and rinse with distilled or deionized water after cleaning.

It should be noted that labware contaminated with biohazardous materials should be disposed of safely. In the event that it is to be cleaned, an autoclave should be employed. Since many of your lab instruments are delicate, the key is to deliver fast, thorough results without causing damage. Ultrasonic lab equipment cleaning is the perfect solution since cavitation is very gentle while cleaning the entire surface. An ultrasonic cleaner is very effective for cleaning lab tools, microscopy parts, embedded samples, specimen mounts, etc. Like glassware and plasticware, they should be rinsed with deionized water so that they dry properly.

As you can see, the versatile capabilities of a laboratory ultrasonic cleaner make it the perfect solution for your lab. It is ideal for ultrasonic cleaning labware, both glass and plastic, and gentle enough to clean your delicate instruments. You can avoid the harshness of strong alkaline solutions that can damage glass and plastic as well as the scrubbing that can cause scratches.  You will also reduce cleaning time, energy, as well as the risks involved with manual cleaning.

That means doing your monthly self exams, and getting yearly check ups at the doctors office. If you are in denial and think that it won't happen to you, think again. It can happen to anyone, even in males.

The different techniques, used today, has advanced over the years.
Let's take a look at some advantages we have to detect early stage of breast cancer through Medical review.
Mammography with Computer Aided Detection:
Mammograms are a great way to catch any early detection of cancer. Mammography is a an x-ray film of the breasts that is read by a Radiologist that checks to see if there is any abnormal findings. The Computer Aided Detection is a process that is computer based and it analyzes the mammogram for any abnormal tissue and shows the Radiologist where the abnormal tisse is, if there is any located.
Digital Mammography
Digital Mammography is a tool used to record an image of an x-ray of the breasts. The images are shown on a monitor and the doctors are able to enhance or manipulate the image for detection, before they print the image out on film.
Ultrasound
Ultrasounds are a high-frequency sound wave that produces pictures called sonograms. These help the Doctors to distinguish if a lump or abnormal tissue is a tumor or a cyst. Ultrasounds are not only used as a diagnostic image, but also to help guide biopsy procedures of breast tissue, like fine needle aspirations. Ultrasounds are usually done after the result of an abnormal mammogram that might show micro calcifications or other abnormal tissue.
MRI (Magnetic Resonance Imagining)
MRI's is a procedure done that doesn't use radiation. There is a magnet that is connected to a computer that then creates the images of what is inside the body. When a breast MRI is obtained there are a lot of images that are created from front to back, top to bottom and side to side. The patient gets on the scanning table and lie on their stomach. The breasts hang into a hollow in the table that has coils that detect any type of magnetic signal. Then the patient is moved into the tube like machine that has the magnet. This helps to improve any cancerous tumor visibility. A radiologist reads the results of MRI's also
Fine Needle Aspirations
A fine needle aspiration distinguishes what type of tumor the patient has. There are solid tumors and liquid-filled tumors; which are cysts. How the procedure works is the doctor takes a fine needle and inserts it into the location of the tumor. The fluid in the tumor is then removed and sent to laboratory to see if the tumor has cancerous cells or not.
Surgical Biopsy
Surgical biopsies are usually done if the mass is a solid tumor. There are two different types of surgical biopsies, excisional, and incisional. Incisional biopsies are performed by removing only a small portion of the abnormal tissue to be examined by a pathologist. With excisional biopsies the whole tumor is removed with a small amount of tissue surrounding it, and then sent to a pathologist to examine.
There are other procedures that are used for detection of breast cancer. The techniques that are listed above are the most common procedures used for patients today. Newer diagnostic imaging and techniques are being developed that are guaranteed to catch early detection and identify patients that are at a high risk of breast cancer. Infrared Thermographic Imaging is a new discovery that picks up any subtle changes that have occurred in the breast pathology. Another new advancement for early detection is Gamma imaging camera that is used with an MRI that can pick up a cancerous tumor that is within the breast. There are always new advances in technology that will help improve the techniques to find early detection of breast cancer. One of these days there will be a cure, but for now concentrate on getting early detection before it becomes too late.

Home Nursing Care Cleaning Chores Get Easier with A Professional Ultrasonic Cleaner

Home nursing has its share of messiness. Getting the equipment clean can quickly become frustrating chore as you may not have access to the right cleaning equipment as you would if you were in a hospital.

If you are a fan of Grey's Anatomy or a similar medical show, you'll know that a cut up human body is a mess of blood and guts and gore. Naturally during the surgery, some of that will stick to the scalpels, clamps, surgical scissors and so on – and they need to be cleaned thoroughly before they can be reused. Similarly, when you visit the dentist, you want to be sure that whatever he puts in your mouth is spotlessly clean and hygienic.

Generally, one thinks of sterilization in connection with medical and surgical instruments. However, sterilization only destroys micro-organisms that may inhabit the instruments; it does not remove blood, saliva, tissue and other debris. In fact, if even tiny amounts of contaminants remain on the instruments, the sterilization process may not be 100% effective. For complete removal of micron level impurities, the answer lies in ultrasonic cleaning coupled with an autoclave that will sterilize the instruments at the microbial layer.

Ultrasonic cleaners produce very high frequency, high energy sound waves that create tiny, partial vacuum bubbles in a liquid medium.  A process known as cavitation. These bubbles practically blast contaminants off the instruments to be cleaned. While simultaneously, they are so tiny that they can penetrate the smallest cavity and do not damage the instrument or denture.

Ultrasonic cleaners come in different sizes and can be adapted for different applications. Moreover, they are compact units that can be tucked away unobtrusively in a corner of the room and do not need a climate-controlled environment. Ultrasonic cleaning is non-messy and efficient and does not require much physical exertion. Thus the cleaners can be used even by old people and invalids.

Dentists are finding ultrasonic cleaners to be almost indispensible. By using ultrasonic technology, they can be confident that new crowns are completely clean before they are sterilized and affixed, thus virtually eliminating the risk of infection. Moreover, ultrasonic cleaning ensures that dental picks, scrapers and other instruments are completely hygienic before they are inserted into the patient's mouth. Even at home, dental ultrasonic cleaners eliminate the physical effort involved in hand scrubbed, avoid the risks of the dentures getting scratched, or contaminants getting accidently transferred from fingers or hand gloves. And, of course, they ensure comprehensive cleaning not achievable with manual methods. Specific models adapted to dentistry are now commercially available that can achieve complete cleaning in less than 10 minutes.

In hospitals and clinics, ultrasonic cleaners have proved their convenience and efficiency so comprehensively that they have become standard fixtures. Part of their appeal has to do with simple economics. It is not practical or feasible to replace every minor surgical instrument after it has been used and soiled; and manual cleaning would be too labour intensive, besides being less than foolproof. Ultrasonic cleaning overcomes all these constraints; and renders the instruments ready for direct sterilization.

Ultrasonic cleaners, then, are now ubiquitous in all areas of medicine and dentistry, not only in hospitals, but also at home. Home care patients are discovering that a compact unit is not only convenient, efficient and easy to use, but also effects significant saving by reducing visits to the clinic or laboratory.
