Watch as Dr. Benjamin Carson performs risky brain surgery on young Payton to remove a brain tumor. Dr. Carson, director of pediatric neurosurgery, is just one of the many reasons why Johns Hopkins Children's Center was recently ranked #1 in neurology and neurosurgery in America's Best Children's Hospitals 2008
Skin Cysts Cysts are noncancerous, closed pockets of tissue that can be filled with fluid, pus, or other material. Cysts are common on the skin and can appear anywhere. They feel like large peas under the surface of the skin. Cysts can develop as a result of infection, clogging of sebaceous glands (oil glands), or around foreign bodies, such as earrings.
This is an example of a surgery to fix a femur (thigh bone) fracture utilizing an intramedullary nail. This is a minimally invasive way of fixing this surgical problem and allows for immediate range of motion and full weight-bearing.
An appendectomy (sometimes called appendisectomy or appendicectomy (British English)) is the surgical removal of the vermiform appendix. This procedure is normally performed as an emergency procedure, when the patient is suffering from acute appendicitis. In the absence of surgical facilities, intravenous antibiotics are used to delay or prevent the onset of sepsis; it is now recognized that many cases will resolve when treated perioperatively. In some cases the appendicitis resolves completely; more often, an inflammatory mass forms around the appendix, causing transruptural flotation. This is a relative contraindication to surgery.
This is a diabetic foot ulcer. The patient reportedly went on vacation and noticed this ulcer upon their return. Debridement (removal of damaged tissue) to the level of healthy bleeding tissue is medically necessary as damaged tissue acts an impediment to wound healing. Due to their diabetic neuropathy, they did not feel any pain or indication that a wound was forming. This ulcer appeared to have penetrated to the level of subcutaneous tissue or even fascia, but turned out to be much deeper than that. These are serious wounds and are the beginnings of what lead to foot and leg amputations if they are not treated promptly by your healthcare provider, AKA Podiatrist.
Prenatal repair of myelomeningocele (MMC), the most common and severe form of spina bifida, is a delicate surgical procedure where fetal surgeons open the uterus and close the opening in the baby's back while they are still in the womb.
Hyperkalemia is defined as a serum potassium concentration higher than the upper limit of the normal range; the range in infants and children is age-dependent, whereas the range for adults is approximately 3.5-5.5 mEq/L. The upper limit may be considerably higher in young or premature infants, as high as 6.5 mEq/L.[5] Degrees of hyperkalemia are defined as follows[6] : 5.5-6.0 mEq/L – Mild 6.1-7.0 mEq/L – Moderate ≥7.0 mEq/L – Severe levels higher than 7 mEq/L can lead to significant hemodynamic and neurologic consequences. levels exceeding 8.5 mEq/L can cause respiratory paralysis or cardiac arrest and can quickly be fatal. Because of a paucity of distinctive signs and symptoms, hyperkalemia can be difficult to diagnose. Indeed, it is frequently discovered as an incidental laboratory finding. The physician must be quick to consider hyperkalemia in patients who are at risk for this disease process. (See Etiology.) However, any single laboratory study demonstrating hyperkalemia must be repeated to confirm the diagnosis, especially if the patient has no changes on electrocardiography (ECG). Because hyperkalemia can lead to sudden death from cardiac arrhythmias, any suggestion of hyperkalemia requires an immediate ECG to ascertain whether ECG signs of electrolyte imbalance are present (see Workup). Continuous ECG monitoring is essential if hyperkalemia is confirmed. Other testing is directed toward uncovering the condition or conditions that led to the hyperkalemia (see Workup). The aggressiveness of therapy for hyperkalemia is directly related to the rapidity with which the condition has developed, the absolute level of serum potassium, and the evidence of toxicity. The faster the rise of the potassium level, the higher it has reached, and the greater the evidence of cardiotoxicity, the more aggressive therapy should be. In severe cases, treatment focuses on immediate stabilization of the myocardial cell membrane, rapid shifting of potassium to the intracellular space, and total body potassium elimination. In addition, all sources of exogenous potassium should be immediately discontinued. (See Treatment.)
reast Augmentation: From Cost to Complications || Common gynaecological problems in women Breast augmentation (aka augmentation mammaplasty) is one of the most popular cosmetic procedures performed in the U.S. today. Despite controversy over the use of silicone breast implants, women have shown a continuing and growing eagerness to surgically enhance the size and shape of their breasts. If you are a healthy, non-smoking women who are at or near their ideal weight, with enough of their own breast tissue to cover and support an implant adequately, then you are a good candidate for breast augmentation surgery.
