PRK Lasek
PRK Lasek Doctor 13,547 Views • 3 years ago

In PRK the epithelium (top layer of the cornea) is scraped off and then the laser treatment is applied. A contact lens is used as a "bandage" to decrease discomfort. The epithelium then grows back over the bare area during the next few days.

In LASEK the epithelium is exposed to 20% alcohol which helps separate epithelium from the cornea. The epithelium is pushed to one side and laser treatment applied. The epithelial layer is replaced back onto the eye and held in place with a contact lens. The contact lens is then removed a few days later. LASEK is hence a "no knife"/flap operation.

Epi-Lasik is a similar procedure that uses a keratome like that used for Lasik, but engineered to only separate the epithelium. The epithelium is left on a hinge, laser treatment applied and flap replaced.

When the hematocrit rises to 60 or 70%, which it often does in polycythemia, the blood viscosity can become as great as 10 times that of water, and its flow through blood vessels is greatly retarded because of increased resistance to flow. This will lead to decreased oxygen delivery.

Pneumothorax Easy explanation
Pneumothorax Easy explanation samer kareem 1,890 Views • 3 years ago

A pneumothorax occurs when some of the tiny air sacs (alveoli) in a baby's lung become overinflated and burst. This causes air to leak into the space between the lung and chest wall (pleural space). The most common cause of pneumothorax is respiratory distress syndrome. This is a condition that occurs in babies who are born too early (premature). The baby's lungs lack the slippery substance (surfactant) that helps them stay open. Therefore, the tiny air sacs are not able to expand as easily. If the baby is put on a breathing machine (mechanical ventilator), there is extra pressure on the baby's lungs, which can sometimes burst the air sacs.

Keratoderma Blennorrhagicum is a manifestation on the skin that appears in patients diagnosed with reactive arthritis (this condition was previously known as Reiter syndrome). The condition manifests itself by lesions that appear on the skin, initially on the palm of the hands and soles of the feet. The lesions have the tendency to spread, affecting other parts of the body, such as the scrotum, scalp or trunk. Because of their appearance, the lesions might be easily confused with the ones from psoriasis. Keratoderma blennorrhagicum is one of the symptoms that can be used for the clinical diagnosis of reactive arthritis.

Curettage, electrosurgery, and laser surgery are more likely than cryotherapy to leave scars, so they are usually reserved for hard-to-remove or recurring warts. If you have a large area of warts, curettage may not be an effective treatment. Some surgical treatments may be too painful for some children.
