Cardiac arrest usually results from an electrical disturbance in the heart. It's not the same as a heart attack. The main symptom is loss of consciousness and unresponsiveness. This medical emergency needs immediate CPR or use of a defibrillator. Hospital care includes drugs, an implantable device, or other procedures.

Robotics is the engineering science and technology of robots, and their design, manufacture, application, and structural disposition.

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.

Cardioversion takes minutes. The patient is sedated (for a few minutes) and then a shock is delivered. The heart nearly always goes back to regular sinus rhythm. ... Patients without prior ablation or heart surgery rarely develop non-right atrial flutter.

Surgical removal of mucocele from lower lip

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

Infant jaundice is a yellow discoloration in a newborn baby's skin and eyes. Infant jaundice occurs because the baby's blood contains an excess of bilirubin (bil-ih-ROO-bin), a yellow-colored pigment of red blood cells. Infant jaundice is a common condition, particularly in babies born before 38 weeks gestation (preterm babies) and some breast-fed babies. Infant jaundice usually occurs because a baby's liver isn't mature enough to get rid of bilirubin in the bloodstream. In some cases, an underlying disease may cause jaundice. Treatment of infant jaundice often isn't necessary, and most cases that need treatment respond well to noninvasive therapy. Although complications are rare, a high bilirubin level associated with severe infant jaundice or inadequately treated jaundice may cause brain damage.

A pelvic mass is a general term for any growth or tumor on the ovary or in the pelvis. A pelvic mass can be cystic (cystadenoma), solid (fibroma), or both (dermoid). A pelvic mass can be benign or malignant.

Initial symptoms may include: Pain or discomfort in the upper tummy (abdomen), especially after eating. Indigestion. (Note: most people who have indigestion do not have stomach cancer.) Feeling sick, and being off food. ... Weight loss and/or loss of appetite. You may pass blood out with your stools (faeces).
