On Tuesday May 29th at 3:00pm EDT, University Hospitals Case Medical Center Cleveland, Ohio, will host a live webcast to demonstrate the removal of brain tumor and epileptic focus from an awake patient using intra-operative MRI and brain mapping. See this on OR-Live.com
The patient was a middle-aged gentleman with new onset seizures. An MRI showed what appeared to be a low grade glioma near the motor strip on the right. Studies have shown that complete removal can cure the seizures, improve quality of life and survival, but this is difficult to do with conventional technology without harming the surrounding normal brain because its difficult to determine where tumor ends and normal brain begins.
Lupus is an autoimmune disease that can affect almost any part of your body, most often your joints, skin, kidneys, heart, lungs, blood, or brain. Your two kidneys are part of your renal system, which also includes two ureters, the bladder, and the urethra. As the primary organs of the renal system, your kidneys are responsible for: Maintaining the correct amount and type of body fluids Removing waste products and toxic substances Regulating the hormones (chemical messengers) that help control blood pressure and blood volume
minimally invasive procedure is the new gold standard for hemorrhoidectomy, according to American and European experts in the field. The procedure, known as PPH (procedure for prolapse and hemorrhoids) stapled hemorrhoidectomy, combines hemorrhoidal devascularization and repositioning to return the veins to the anal canal. “This year, this is the revolutionary new procedure in the United States,” Gary Hoffman, MD, clinical faculty member in general and colorectal surgery, Cedars-Sinai Medical Center, Los Angeles, told General Surgery News after moderating a live PPH telesurgery at the 2003 annual meeting of the Society of American Gastrointestinal Endoscopic Surgeons.
Skin cancer is the most common of all cancer types, accounting for an estimated one third of all new cases. It’s important to take the right steps to ensure proper protection and adopt good sun care habits no matter what your age or stage in life.
his patient had spilled boiling water on his lower leg a couple days before. This isn't complicated but the teaching points should focus on draining the large blistered areas and attempting to maintain moisture as long as we can so the skin doesn't contract down on itself.
Rare condition disorder known as Diprosopus, also known as craniofacial duplication. Diprosopus is a congenital defect also known as craniofacial duplication. The exact description of diprosopus refers to a fetus with a single trunk, normal limbs, and facial features that are duplicated to a certain degree. A less severe instance is when the fetus has a duplicated nose and the eyes are spaced far apart. In the most extreme instances, the entire face is duplicated, hence the name diprosopus, which is Greek for two-faced. Fetuses with diprosopus often also lack brains (anencephaly), have neural tube defects, or heart malformations. In some cases, if the brain is formed, it may have duplicated structures. Most infants with diprosopus are stillborn and there are fewer than fifty cases documented since 1864.
-Tibial stress fractures are common in athletes and nonathletes who suddenly increase their physical activity. Clinical features include pain, localized tenderness, and swelling. Plain x-ray is <50% sensitive for stress fractures, especially in the first 2-3 weeks after the onset of symptoms. MRI is preferred over bone scan or ultrasound as it can show the fracture line that extends through the cortex into the medullary line. MRI can also identify ligament, muscle, and cartilage injuries. However, MRI findings may be persistently abnormal for up to 1 year after the stress fracture has healed.
LASIK or Laser-Assisted In Situ Keratomileusis is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses.
LASIK surgery is most commonly performed as a cure for myopia (nearsightedness), but can also be used to cure hyperopia (farsightedness) or astigmatism (corneal irregularities).
LASIK is a procedure that permanently changes the shape of the cornea using a special laser and thus focusing the light rays exactly on the retina.
The steps of the procedure are as follows:
A suction ring is placed on the eye to stabilize and check the eye pressure.
The microkeratome, a cutting instrument, is attached to the suction ring.
The blade of the microkeratome is used to cut a flap in the cornea.
The exposed inner layer of the cornea is then reshaped with an excimer laser.
The corneal flap is returned to its original position.
LASIK is an ambulatory procedure; the patient can walk into the surgery center, have the procedure and walk out again and is awake the whole time. Occasionally, the doctor may administer a mild oral sedative.

Tooth colored composite fillings are chemically bonded to teeth. For this reason, the placement of white fillings does not always require numbing the area being restored. Numbing (anesthetizing) the area is often required if tooth decay has progressed beneath the enamel layer and into the underlying dentin layer which surrounds the nerve of the tooth. Once decay is removed, the tooth is cleaned and a primer (weak acid) is applied to the area being restored. The primer opens pores in the enamel and dentin. A bonding agent is then flowed into the open pores and cured. Curing prepares the bonding agent to adhere to the tooth colored filling material. The filling material is then placed inside the tooth. After shaping the tooth colored filling material to resemble the natural anatomy of your tooth it is hardened by curing with a strong curing light. Once the white filling hardens, your bite will be checked to make sure your teeth fit together properly. If the tooth filling extends into the space between your teeth your dentist will also make sure you can floss between your teeth properly. Adjustments will be made if necessary followed by smoothing and polishing of your new filling..
