ost of us come across this particular sign quite often. Of course, you can just jump to the numerous investigations and one after another, rule out the possible causes, finally getting to the diagnosis. For me, that’s no fun at all. Although I still don’t know whether I am going to become a surgeon or not (embarassing for me, since I’m going to be done with med-school this year), its pretty fascinating. If I were to work in a country whether investigations aren’t that expensive, I would definitely just perform a small examination and take a short history, sending off my patient to get a myriad of investigations, reporting to me after a while, with the diagnosis in his reports.

New York Plastic Surgery ,Dr. Robert Vitolo ,board certified plastic surgeon , brings you into the operating room for a glimpse at how his transumbilical breast augmentation procedure is performed. Dr. Vitolo, a pioneer in the 'no visible scar' breast enlargement surgery, has been using this technique since 1994. Dr. Vitolo use Allergan Natrelle saline breast implants and Mentor saline implants. Dr. Vitolo also performs a removal of silicone gel implants and replacement with saline implants using the transumbilical method.
The exam should be performed in an orderly fashion as follows: 1. Have the patient stick out their tongue so that you can examine the posterior pharynx (i.e. the back of the throat). Ask the patient to say "Ah", which elevates the soft palate, giving you a better view. If you are still unable to see, place the tongue blade � way back on the tongue and press down while the patient again says "Ah," hopefully improving your view. This causes some people to gag, particularly when the blade is pushed onto the more proximal aspects of the tongue. It may occasionally be important to determine whether the gag reflex is functional (e.g. after a stroke that impairs CNs 9 or 10; or to determine if a patient with depressed level of consciousness is able to protect their airway from aspiration). This is done by touching a q-tip against the posterior pharynx, uvula or tongue. It is not necessary to do this during your routine exam as it can be quite noxious!
2. Note that the uvula hangs down from the roof of the mouth, directly in the mid-line. With an "Ah," the uvula rises up. Deviation to one side may be caused by CN 9 palsy (the uvula deviates away from the affected side), a tumor or an infection. CN9 Pasly Cranial Nerve 9 Dysfunction: Patient has suffered stroke, causing loss of function of left CN 9. As a result, uvula is pulled towards the normally functioning (ie right) side. 3. The normal pharynx has a dull red color. In the setting of infection, it can become quite red, frequently covered with a yellow or white exudate (e.g. with Strep. Throat or other types of pharyngitis).
4. The tonsils lie in an alcove created by arches on either side of the mouth. The apex of these arches are located lateral to and on a line with the uvula. Normal tonsils range from barely apparent to quite prominent. When infected, they become red, are frequently covered by whitish/yellow discharge. In the setting of a peritonsilar abscess, the tonsils appear asymmetric and the uvula may be pushed away from the affected side. When this occurs, the tonsil may actually compromise the size of the oral cavity, making breathing quite difficult.
5. Look carefully along the upper and lower gum lines and at the mucosa in general, which can appear quite dry if the patient is dehydrated.
6. Examine the teeth to get a sense of general dentition, particularly if the patient has a dental complaint. Pain produced by tapping on a tooth is commonly caused by a root abscess. Tooth Abscess: Tooth abscess involving left molar region. Associated inflammation of left face can clearly be seen. 7. Have the patient stick their tongue outside their mouth, which allows evaluation of CN 12. If there is nerve impairment, the tongue will deviate towards the affected side. Any obvious growths or abnormalities? Ask them to flip their tongue up so that you can look at the underside. If you see something abnormal, grasp the tongue with gauze so that you can get a better look. Left CN 12 Dysfunction: Stroke has resulted in L CN 12 Palsy. Tongue therefore deviates to the left.
8. Make note of any growths along the cheeks, hard palate (the roof of the mouth between the teeth), soft palate, or anywhere else. In particular, patients who smoke or chew tobacco are at risk for oral squamous cell cancer. Any areas which are painful or appear abnormal should also be palpated. Put on a pair of gloves to better explore these regions. What do they feel like? Are they hard? To what extent does a growth involve deeper structures? If the patient feels something that you cannot see, try to get someone else to hold the light source, freeing both your hands to explore the oral cavity with two tongue depressors.
Highlights of a fetal laser surgery for twin-to-twin transfusion syndrome (TTTS) will be shown from Tampa General Hospital
TTTS affects 10 to 15 percent of identical-twin pregnancies and is the result of abnormal blood exchange between identical twins through a common placenta. The larger of the twins, or recipient, is surrounded by too much amniotic fluid and in danger of heart failure as its body tries to pump the overwhelming volume of blood intended for both. The smaller, or donor twin, is encased in a shrinking amniotic sac deprived of blood. Without treatment, both will likely die.
Rubén Quintero, M.D., Medical Director of Maternal Fetal Medicine/Fetal Surgery at Tampa General Hospital and Professor and Director of the Division of Maternal Fetal Medicine, Department of Obstetrics and Gynecology, University of South Florida College of Medicine will narrate the procedure and answer e-mail questions live as taped highlights of the procedure are shown.
The pelvic floor or pelvic diaphragm is composed of muscle fibers of the levator ani, the coccygeus, and associated connective tissue which span the area underneath the pelvis. The pelvic diaphragm is a muscular partition formed by the levatores ani and coccygei, with which may be included the parietal pelvic fascia on their upper and lower aspects. The pelvic floor separates the pelvic cavity above from the perineal region (including perineum) below.
The right and left levator ani lie almost horizontally in the floor of the pelvis, separated by a narrow gap that transmits the urethra, vagina, and anal canal. The levator ani is usually considered in three parts: pubococcygeus, puborectalis, and iliococcygeus. The pubococcygeus, the main part of the levator, runs backward from the body of the pubis toward the coccyx and may be damaged during parturition. Some fibers are inserted into the prostate, urethra, and vagina. The right and left puborectalis unite behind the anorectal junction to form a muscular sling . Some regard them as a part of the sphincter ani externus. The iliococcygeus, the most posterior part of the levator ani, is often poorly developed.
The coccygeus, situated behind the levator ani and frequently tendinous as much as muscular, extends from the ischial spine to the lateral margin of the sacrum and coccyx.
The pelvic cavity of the true pelvis has the pelvic floor as its inferior border (and the pelvic brim as its superior border.) The perineum has the pelvic floor as its superior border.
Some sources do not consider “pelvic floor” and “pelvic diaphragm” to be identical, with the “diaphragm” consisting of only the levator ani and coccygeus, while the “floor” also includes the perineal membrane and deep perineal pouch. However, other sources include the fascia as part of the diaphragm. In practice, the two terms are often used interchangeably.
Inferiorly, the pelvic floor extends into the anal triangle.

Liposuction is a surgical procedure that is done to remove fat deposits from underneath the skin. Common areas that are treated: the abdomen, buttocks, thighs, upper arms, chest and neck. (use medical graphic of body with labeled parts) The procedure is usually done as an outpatient under some combination of local anesthesia and/or sedation:. This means you are awake but relaxed and pain free. Depending on the number of areas to be treated and the specific technique selected, it may take from one to several hours. A small incision (cut) is made through the skin near the area of the fat deposit. Multiple incisions may be needed if a wide area or multiple areas are being done. A long hollow tube called a cannula will be inserted through this incision. Prior to inserting the cannula, the doctor may inject a solution of salt water that contains an anesthetic (numbing) medication and another medication to decrease bleeding. The cannula is then inserted and moved under the skin in a way to loosen the fat deposits so they may be suctioned out. Because a significant amount of body fluid is removed with the fat, an intravenous (through the veins) fluid line will be kept going during the procedure.
A recent technique called “ultrasound-assisted lipoplasty” uses a special cannula that liquefies the fat cells with ultrasonic energy. You should ask your doctor which technique he/she will use and how it will affect the type of anesthesia you will need and the length of the procedure.
Why is this procedure performed?
Liposuction is done to restore a more normal contour to the body. The procedure is sometimes described as body sculpting. It should be limited to fat deposits that are not responsive to diet and exercise. It is suggested that you should be within 20of your ideal body weight at the time of surgery. If you are planning to lose weight you should delay this procedure. This is not obesity surgery. The maximum amount of fat that can be removed is usually less than 10 pounds. The best results are achieved in people who still have firm and elastic skin. Although rare, there are risks and complications that can occur with liposuction. You should be aware that all the complications are increased if you are a smoker. You will need to quit smoking or at least avoid smoking for a month before and after surgery. If you have had prior surgeries near any of the areas to be treated, this may increase the risk of complications and you should discuss this with your doctor. Any history of heart disease, diabetes, bleeding problems or blood clots in your legs may make you more prone to post-operative problems and you should discuss these with your doctor. Finally, as with any cosmetic procedure it is important to have realistic expectations. The goals, limitations, and expectations of the procedure should be discussed openly and in detail with your doctor. Most insurance companies do not cover cosmetic surgery.
What should I expect during the post-operative period?
After surgery you should be able to go home but you will need someone to drive you. In the first few days after surgery it is common for the incisions to drain fluid and you will have to change dressings frequently. Fresh blood is not usual and if you have any bleeding you should call your doctor immediately. In some cases a small tube may have been placed through the skin to allow drainage. You will be limited to sponge baths until the drains and dressings are removed. After that you may take showers but no baths for 2 weeks. You may experience pain, burning, and numbness for a few days. Take pain medicine as prescribed by your doctor. You may notice a certain amount of bruising and swelling. The bruising will disappear gradually over 1 to 2 weeks. Some swelling may last for up to 6 months. If you have skin sutures they will be removed in 7 to 10 days. You should be able to be up and moving around the house the day after surgery but avoid any strenuous activity for about 1
