Today, hair transplant physicians are able to make use of different techniques to extract and transplant large numbers of hair follicles (follicular units). There are two primary techniques for hair transplantation currently in use. The FUE (Follicular Unit Extraction) and the FUT (Follicular Unit Transplantation) methods. They differ primarily in the way hair follicles are extracted from the donor area. Follicular Unit Transplantation (FUT) The FUT process involves removing a small strip of tissue from the back of the head, from which the donor hair follicles will be extracted. The hair follicles are harvested from the strip by a skilled clinical team before being individually transplanted to the recipient areas. In most cases, and especially cases of advanced hair loss, FUT is the preferred method because it allows the physician to fully utilize the scalp area to deliver results consistent with patient expectations. FUT typically allows for the greatest number of grafts to be transplanted in a single session. Pain Management Some patients report higher levels of discomfort with FUT procedures compared to FUE due the potential swelling in the area where the strip of tissue was removed, but both methods have a very manageable recovery period and pain medication can be prescribed by your physician if needed. Both techniques of hair transplantation are relatively simple. Hair transplantation procedures are outpatient surgeries with some patients going back to work as soon as the very next day. Scarring The FUT strip extraction method typically results in a very narrow linear scar in the back of the head (typically 1mm in diameter or less in size). Since the scar is very thin, it’s easily concealed by all but the shortest of haircut styles. A short to moderate crop setting on most clippers is sufficient to conceal the scar for the majority of patients, and over time the scar will become less noticeable as it fades. Costs The industry norm for pricing is on a per-graft basis. This allows each individual to pay for only what they need and receive in number of grafts, and not a flat rate that in the end may cost you more. The per-graft cost of a FUT procedure is generally lower than that of a FUE procedure. Lately however, in response to the rising popularity of the FUE technique, many hair transplantation clinics have started lowering the per graft cost on FUE procedures, so that the cost difference between the two types of procedure are not as much as most people think. The costs of medical procedures always vary by patients’ conditions, needs and objectives. For the most accurate assessment of your hair loss and the associated cost of your hair restoration, you will need to speak to a physician. Follicular Unit Extraction (FUE) In an FUE hair transplantation, each follicular unit is individually taken directly from the scalp with no strip of tissue being removed. Hair follicles are removed in a random fashion and the result is less density in the donor area that many say is not even noticeable. This is the main difference between FUE & FUT. Since follicles are removed one at a time, fewer follicles can be harvested during a typical session, making FUE a better option to restore hair in smaller cases (number of grafts) compared to the traditional FUT method. FUE is constantly evolving and what was once utilized for only smaller cases is now being utilized for larger and larger cases. Some people that prefer the FUE method may have the option of splitting their procedure into two days in order to complete their recommended transplantation goals. Pain Management With no stitches required and no linear scar left to heal, FUE procedures do have a faster healing time and less post-procedure discomfort compared to the traditional FUT procedure. Scarring Since FUE procedures involve removing hairs individually from the scalp, there is no linear scar left behind. However, there will be tiny 1mm in diameter or less puncture marks that tend to heal by themselves after scabbing-over in the days following the procedure. These tiny wounds typically heal within three to seven days. Costs Since the physician must remove each hair follicle individually, the time-sensitive nature of an FUE procedure typically makes it more expensive than an FUT procedure. As stated earlier, FUE technology is improving as well as gaining popularity and many hair restoration practices (including Bosley) have started to lower the cost per graft price for FUE procedures. Nowadays, the cost difference between a FUE and a FUT procedures is less disparate.
What is Venipuncture? While venipuncture can refer to a variety of procedures, including the insertion of IV tubes into a vein for the direct application of medicine to the blood stream, in phlebotomy venipuncture refers primarily to using a needle to create a blood evacuation point. As a phlebotomist, you must be prepared to perform venipuncture procedures on adults, children, and even infants while maintaining a supportive demeanor and procedural accuracy. Using a variety of blood extraction tools, you must be prepared to respond to numerous complications in order to minimize the risk to the patient while still drawing a clean sample. In its entirety, venipuncture includes every step in a blood draw procedure—from patient identification to puncturing the vein to labeling the sample. Patient information, needle placement, and emotional environment all play a part in the collection of a blood sample, and it's the fine details that can mean the difference between a definite result and a false positive. After placing the tourniquet and finding the vein, it's time for the phlebotomist to make the complex choice on what procedure will best suit the specific situation. Keeping this in mind, it should be noted that the following information is not an instructional guide on how to perform these phlebotomy procedures. Rather, the information below is intended to serve as an educational resource to inform you of the equipment and procedures you will use. Venipuncture Technqiues Venipuncture with an Evacuated or Vacuum Tube: This is the standard procedure for venipuncture testing. Using a needle and sheath system, this procedure allows multiple sample tubes to be filled through a single puncture. This procedure is ideal for reducing trauma to patients. After drawing the blood, the phlebotomist must make sure the test stopper is correctly coded and doesn't contact exposed blood between samples. Venipuncture with a Butterfly Needle : This is a specialized procedure that utilizes a flexible, butterfly needle adaptor. A butterfly needle has two plastic wings (one on either side of the needle) and is connected to a flexible tube, which is then attached to a reservoir for the blood. Due to the small gauge of the needle and the flexibility of the tube, this procedure is used most often in pediatric care, where the patients tend to have smaller veins and are more likely to move around during the procedure. After being inserted into a vein at a shallow angle, the butterfly needle is held in place by the wings, which allow the phlebotomist to grasp the needle very close to the skin. Phlebotomists should be careful to watch for blood clots in the flexible tubing. Venipuncture with a Syringe: This technique is typically only used when there is a supply shortage, or when a technician thinks it is the appropriate method. It uses the classic needle, tube, and plunger system, operating in a similar manner to the vacuum tube but requiring multiple punctures for multiple samples. Additionally, after the blood is drawn it must be transferred to the appropriate vacuum tube for testing purposes. If you choose to use this method, remember to check for a sterile seal, and use a safety device when transferring the sample. Fingerstick (or Fingerprick): This procedure uses a medical lance to make a small incision in the upper capillaries of a patient's finger in order to collect a tiny blood sample. It is typically used to test glucose and insulin levels. When performing a Fingerstick, the phlebotomist should remember to lance the third or fourth finger on the non-dominant arm. Never lance the tip or the center of the finger pad; instead, lance perpendicular to the fingerprint lines. Heelstick (or Heelprick): Similar to the Fingerstick procedure, this process is used on infants under six months of age. A medical lance is used to create a small incision on the side of an infant's heel in order to collect small amounts of blood for screening. As with a Fingerstick, the incision should be made perpendicular to the heel lines, and it should be made far enough to the left or right side of the heel to avoid patient agitation. Before performing a Heelstick, the infant's heel should be warmed to about 42 degrees Celsius in order to stimulate capillary blood and gas flow. Therapeutic Phlebotomy: This involves the actual letting of blood in order to relieve chemical and pressure imbalances within the blood stream. Making use of a butterfly needle, this therapy provides a slow removal of up to one pint of blood. Though the blood removed is not used for blood transfusions, the procedure and concerns are the same as with routine blood donation. As with any phlebotomy procedure, one should pay close attention to the patient in order to prevent a blood overdraw. Bleeding Time: A simple diagnostic test that is used to determine abnormalities in blood clotting and platelet production. A shallow laceration is made, followed by sterile swabbing of the wound every 30 seconds until the bleeding stops. Average bleed times range between one and nine minutes. As a phlebotomist, you should familiarize yourself with the application and cross-application of these procedures in order to recognize when a procedure is necessary, and what the risks are for each.
What is Wallenberg syndrome? Wallenberg syndrome is a rare condition in which an infarction, or stroke, occurs in the lateral medulla. The lateral medulla is a part of the brain stem. Oxygenated blood doesn’t get to this part of the brain when the arteries that lead to it are blocked. A stroke can occur due to this blockage. This condition is also sometimes called lateral medullary infarction. The cause of the syndrome isn’t always clear, however.
Any independent vertical movement of the transducer or the patient will affect the hydrostatic column of this fluid-filled system and thus alter the pressure measurements. At some time before or after PAC insertion, the system must therefore be zeroed to ambient air pressure. The reference point for this is the midpoint of the left atrium (LA), estimated as the fourth intercostal space in the midaxillary line with the patient in the supine position. With the transducer at this height, the membrane is exposed to atmospheric pressure, and the monitor is then adjusted to zero. Calibration Once zeroed, the monitoring system must be calibrated for accuracy. Currently, most monitors perform an automated electronic calibration. Two methods are used to manually calibrate and check the system. If the catheter has not been inserted, the distal tip of the PAC is raised to a specified height above the LA. For example, raising the tip 20 cm above the LA should produce a reading of approximately 15 mm Hg if the system is working properly (1 mm Hg equals 1.36 cm H 2 O). Alternatively, pressure can be applied externally to the transducer and adjusted to a known level using a mercury or aneroid manometer. The monitor then is adjusted to read this pressure, and the system is calibrated. Dynamic tuning Central pressures are dynamic waveforms (ie, they vary from systole to diastole) and thus have a periodic frequency. To monitor these pressures accurately, the system requires an appropriate frequency response. A poorly responsive system produces inaccurate pressure readings, and differentiating waveforms (eg, PA from pulmonary capillary wedge pressure [PCWP]) can become difficult. When signal energy is lost, the pressure waveform is dampened. Common causes of this are air bubbles (which are compressible), long or compliant tubing, vessel wall impingement, intracatheter debris, transducer malfunction, and loose connections in the tubing. A qualitative test of the frequency response is performed by flicking the catheter and observing a brisk high-frequency response in the waveform. After insertion, the system can be checked by using the rapid flush test. When flushed, an appropriately responsive system shows an initial horizontal straight line with a high-pressure reading. Once the flushing is terminated, the pressure drops immediately, which is represented by a vertical line that plunges below the baseline. A brief and well-defined oscillation occurs, followed by return of the PA waveform. A dampened system will not overshoot or oscillate, and causes a delay in returning to the PA waveform.
What is a mole? Many people refer to a mole as any dark spot or irregularity in the skin. Doctors use different terms. But the following types of skin marks such as these are not treated the same way moles are and are not discussed here: Birthmarks Abnormal formations of blood vessels (hemangiomas) Keratoses (benign or precancerous spots, which appear after about age 30 years)
Urinary incontinence isn't a disease, it's a symptom. It can be caused by everyday habits, underlying medical conditions or physical problems. A thorough evaluation by your doctor can help determine what's behind your incontinence. Temporary urinary incontinence Certain drinks, foods and medications can act as diuretics — stimulating your bladder and increasing your volume of urine. They include: Alcohol Caffeine Decaffeinated tea and coffee Carbonated drinks Artificial sweeteners Corn syrup Foods that are high in spice, sugar or acid, especially citrus fruits Heart and blood pressure medications, sedatives, and muscle relaxants Large doses of vitamins B or C Urinary incontinence also may be caused by an easily treatable medical condition, such as: Urinary tract infection. Infections can irritate your bladder, causing you to have strong urges to urinate, and sometimes incontinence. Other signs and symptoms of urinary tract infection include a burning sensation when you urinate and foul-smelling urine. Constipation. The rectum is located near the bladder and shares many of the same nerves. Hard, compacted stool in your rectum causes these nerves to be overactive and increase urinary frequency. Persistent urinary incontinence Urinary incontinence can also be a persistent condition caused by underlying physical problems or changes, including: Pregnancy. Hormonal changes and the increased weight of the uterus can lead to stress incontinence. Childbirth. Vaginal delivery can weaken muscles needed for bladder control and also damage bladder nerves and supportive tissue, leading to a dropped (prolapsed) pelvic floor. With prolapse, the bladder, uterus, rectum or small intestine can get pushed down from the usual position and protrude into the vagina. Such protrusions can be associated with incontinence. Changes with age. Aging of the bladder muscle can decrease the bladder's capacity to store urine. Menopause. After menopause women produce less estrogen, a hormone that helps keep the lining of the bladder and urethra healthy. Deterioration of these tissues can aggravate incontinence. Hysterectomy. In women, the bladder and uterus are supported by many of the same muscles and ligaments. Any surgery that involves a woman's reproductive system, including removal of the uterus, may damage the supporting pelvic floor muscles, which can lead to incontinence. Enlarged prostate. Especially in older men, incontinence often stems from enlargement of the prostate gland, a condition known as benign prostatic hyperplasia. Prostate cancer. In men, stress incontinence or urge incontinence can be associated with untreated prostate cancer. But more often, incontinence is a side effect of treatments for prostate cancer. Obstruction. A tumor anywhere along your urinary tract can block the normal flow of urine, leading to overflow incontinence. Urinary stones — hard, stone-like masses that form in the bladder — sometimes cause urine leakage. Neurological disorders. Multiple sclerosis, Parkinson's disease, stroke, a brain tumor or a spinal injury can interfere with nerve signals involved in bladder control, causing urinary incontinence.
