Bone Scan Introduction
Bone Scan Introduction Mohamed 17,965 Views • 2 years ago

A Bone scan or bone scintigraphy is a nuclear scanning test to find certain abnormalities in bone which are triggering the bone's attempts to heal. It is primarily used to help diagnose a number of conditions relating to bones, including: cancer of the bone or cancers that have spread (metastasized) to the bone, locating some sources of bone inflammation (e.g. bone pain such as lower back pain due to a fracture), the diagnosis of fractures that may not be visible in traditional X-ray images, and the detection of damage to bones due to certain infections and other problems.

Nuclear medicine bone scans are one of a number of methods of bone imaging, all of which are used to visually detect bone abnormalities. Such imaging studies include magnetic resonance imaging (MRI), X-ray computed tomography (CT) and in the case of 'bone scans' nuclear medicine. However, a nuclear bone scan is a functional test, which means it measures an aspect of bone metabolism, which most other imaging techniques cannot. The nuclear bone scan competes with the FDG-PET scan in seeing abnormal metabolism in bones, but it is considerably less expensive.

Nuclear bone scans are not to be confused with the completely different test often termed a "bone density scan," DEXA or DXA, which is a low exposure X-ray test measuring bone density to look for osteoporosis and other diseases where bones lose mass, without any bone re-building activity. The nuclear medicine scan technique is sensitive to areas of unusual bone re-building activity because the radiopharmaceutical is taken up by osteoblast cells which build bone. The technique therefore is sensitive to fractures and bone reaction to infections and bone tumors, including tumor metastases to bones, because all these pathologies trigger bone osteoblast activity. The bone scan is not sensitive to osteoporosis or multiple myeloma in bones, and therefore other techniques must be used to assess bone abnormalities from these diseases.

Laparoscopic procedures, EndoGrab (Virtual Ports) Kobi R 13,519 Views • 2 years ago

Virtual Ports, Ltd. (http://www.virtual-ports.com) is a medical device company developing and marketing instruments to improve minimally invasive laparoscopic procedures.
The EndoGrab retraction system reduces the number of ports needed for surgery by eliminating the need for traditional hand held retraction. For the surgeon, this simple solution results in the need for less auxiliary personnel, a decreased overall surgery cost, and more control over the surgery. The EndoGrab also offers added benefit to the patient who will experience less post-operative discomfort and scarring.

The EndoGrab is an internally anchored, hands-free retracting device that is introduced at the start of surgery through a 5mm trocar by means of a proprietary Applier tool. The Surgeon uses the Applier to attach the EndoGrab to both the organ requiring retraction and to the internal abdominal wall, thereby removing the organ from the operative field. The Applier is then removed and the port is free for use by other instruments.

The fetal circulation is the circulatory system of a human fetus, often encompassing the entire fetoplacental circulation that also includes the umbilical cord and the blood vessels within the placenta that carry fetal blood.

The fetal circulation works differently from that of born humans, mainly because the lungs are not in use: the fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord.

Scarless Breast lift using Serdev suture without scars. Mastopexy
Scarless Breast lift using Serdev suture without scars. Mastopexy Doctor 19,670 Views • 2 years ago

METHODS:
Previously existing methods are characterized by unpleasant scars that, despite surgeons promises, remain for life.
Incisions are:

- around the areola (Round block) leading to a flat areola, often unpleasant hypertophic skars, skin rippling.
- inverted T (around the areola, vertically down and in the fold under the breast).

- Vertical (around the areola and vertically down). Due to the extess skin, incisions often turn into inverted L or T. Rearrangement of glandular tissue and skin changes the shape of the breasts and may be different from expectations. Scars worry patients and sometimes cause disturbances in the relationship with their partner.

- No scars. The "Serdev Suture" lifting technique for breast lifting without scars (only points - needle perforations in the skin) is created by the Bulgarian cosmetic surgeon Prof. Dr. Nikolay Serdev. It is a novelty that had changed the cosmetic surgery world in the last 10-14 years for young patients. The technique is especially important in Asia and Latin America, for Asians, African-Americans, Indians, and others who form keloids and lumpy scars after operations.

The Serdev suture method can achieve lift upto and over 14 centimeters and is most suitable for the following types of breasts:
- not very heavy full breasts.
- in the presence of subpectoral implants with subsequent drooping of the breasts after childbirth and lactation.
- empty and loose breasts after childbirth and breastfeeding. In such cases this technique is combined with subpectoral implants. In sagging breasts implants should not be placed in the skin over the pectoral muscles, because thus will lead to even more drooping. Therefore, breast lift requires breast fixation to the level of the pectoral muscle (the normal position in young women), and then placement of appropriate implants under the muscle, to hold them in the appropriated position.
- in drooping breasts after subglandular augmentation (over the muscle). In such cases, patients should not wait until the skin elongation becomes visible. The implants should be removed, the capsule removed - a difficult but a necessary operation, preventing postop seromas and infection. Implants should be placed under the pectoralis muscle to wear them. Patients should orient the cosmetic surgeon at what level they want the nipples - in the middle of the implant, higher or lower.
Implants should be generally replaced - below the muscle implants should be smooth, move naturally without hurting the muscle.

Because of modern anesthetics and new methods without trauma, pain and swelling after surgery are not significant. In 3-4 days, patients can return to social life, even the next day, but it is preferable to rest for 2-3 days.

Exercises with the arms and weight lifting is prohibited for a month and a half.

Due to lack of scars, the breast lift using the Serdev sutures can be repeated to maintain the aesthetic appearence of the breasts even in advanced age.

Gigantomastia i.e. very large, very heavy and drooping breasts can not be operated in this manner, because of gravity and overskin.

Early mastopexy using Serdev sutures is recommended before too much changes in the tissues. If late, more and more complex interventions are required.

"A lot of people are opting for various breast procedures and one of the most common among them is “mastopexy”. This is the surgery that involved uplifting of sagging breasts and, in certain cases, repositioning of the nipple and areola in order to restore normality and beauty. The excess skin is removed and firmness is provided to the breasts. Though mastopexy can be done as a stand alone surgery, many people combine it with breast augmentation which involves inserting implants inside the b

Over one million Americans have the sexually transmitted virus, HIV, which can lead to the deadly disease known as AIDS.
HIV can be transmitted in the sexual fluids, blood or breast milk of an infected person. HIV prevention therefore involves a wide range of activities including prevention of mother-to-child transmission, needle exchanges and harm reduction for injecting drug users, and precautions for health care workers.

EHEC Outbreak News - Expecting more cases in Germany
EHEC Outbreak News - Expecting more cases in Germany Scott Stevens 6,784 Views • 2 years ago

The E.coli bacteria has claimed 14 lives and infected more than 300 hundred in the country. It has now spread to other European states.

Facing an increasing number of cases, German health authorities warned people to avoid eating raw cucumber, tomatoes and lettuce.

Reinhard Burger, President of Robert Koch Institute, said, "As for the present situation there is no reason to give the all-clear yet and it is possible the original source of the infection is still active and could lead to further infections."

The first cases of the EHEC outbreak were noticed in Northern Germany, but infections are now spreading across the country.

Cases haves spiked compared to other years, and are still rising.

Daniel Bahr, German Health Minister, said, "The result is that we unfortunately still have to prepare for a rising number of cases. Exercising caution is still recommended and we ask our citizens to be particularly careful. "

But, the German government says it's working around the clock to stop the outbreak and clarify how it arose.

Ilse Aigner, German Agriculture Minister, said, "Together, we face a big challenge to piece together hundreds or thousands of mosaic pieces from Germany and abroad into an overall picture that gives us a clear answer on how this terrible infection arose. "

In the meantime, experts are advising not to eat pre-packaged or prepared salad, which may contain the bacteria.
