This video clip shows an upper track endoscopy of A 75 year-old female, presented with severe adominal pain since three days. Endoscopy displays a deep ulcer at the lesser curvature of the stomach. This patient has a klatskin´s tumor (bile duct bifurcation).
SCOOP transtracheal oxygen is indicated for patients with chronic hypoxemia which persists in spite of optimal medical therapy. Arterial blood gases obtained while breathing room air should show a PaO2< 55 mm Hg. SCOOP transtracheal oxygen is also indicated for patients with a PaO2 of 56-59 mm Hg ...
if they also have: 1) dependent edema suggesting congestive heart failure, 2) "P" pulmonale on EKG (P wave greater than 3mm in standard leads II, III or AVF), or 3) erythrocythemia with a hematocrit of >55%.
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.

A thin polymer film that seals surgical wounds could make sutures a relic of medical history.
Measuring just 50 microns, the film is placed on a surgical wound and exposed to an infrared laser, which heats the film just enough to meld it and the tissue, thus perfectly sealing the wound. Known as Surgilux, the device's raw material is extracted from crab shells and has Food and Drug Administration approval in the US
