If you are tired of dealing with glasses or squinting to read signs in the distance, then you should consider LASIK Eye Surgery. In this outpatient refractive procedure, lasers are used to correct vision issues by changing the structure of the cornea. This may entirely eliminate reliance upon glasses or contacts. In this interactive LASIK Eye Surgery, you will assist in numbing the patient’s eye and cleaning the area for the procedure. With a speculum, you will hold the eye open, mark the cornea using a water-soluble ink, then attach a suction ring to it. After that, a specialized blade device is used to cut into the corneal flap and peel it back so that the laser can clear away corneal tissue underneath. This process corrects the shape of the cornea in less than a minute before putting the corneal flap back in place. After the procedure, we will go over LASIK Eye Surgery recovery instructions. Scrub in and let’s get started!
A circulatory anastomosis is a connection (an anastomosis) between two blood vessels, such as between arteries (arterio-arterial anastomosis), between veins (veno-venous anastomosis) or between an artery and a vein (arterio-venous anastomosis). An end artery (or terminal artery) is an artery that is the only supply of oxygenated blood to a portion of tissue. Examples of an end artery include the splenic artery that supplies the spleen and the renal artery that supplies the kidneys.
What is a brain aneurysm? A brain (cerebral) aneurysm is a bulging, weak area in the wall of an artery that supplies blood to the brain. In most cases, a brain aneurysm causes no symptoms and goes unnoticed. In rare cases, the brain aneurysm ruptures, releasing blood into the skull and causing a stroke. When a brain aneurysm ruptures, the result is called a subarachnoid hemorrhage. Depending on the severity of the hemorrhage, brain damage or death may result.
A surgeon begins the PPH stapled hemorrhoidectomy by inserting a circular anal dilator and obturator into the anal canal and then securing the dilator in place with four sutures. The surgeon then inserts a PPH anoscope into the obturator. Next, he places a circumferential purse-string suture of 2-0 Monocryl on a UR-6 needle 4 cm proximal to the dentate line. The surgeon opens a PPH stapler and places its anvil across the purse string. The stapler is then closed and fired; it is held closed for two minutes to improve hemostasis. Prior to firing the stapler in a female patient, the surgeon places a gloved finger in the vagina to ensure the vaginal mucosa and rectal-vaginal septum are not trapped within the jaws of the closed stapler. The surgeon then opens and removes the stapler.
The Skin Cancer Foundation, founded in 1979 by dermatologist and Mohs surgeon Perry Robins, MD, is a global organization solely devoted to educating the public and medical community about skin cancer prevention, early detection, and treatment
What Are Sleep Disorders? Circadian Rhythm Disorders Typically, people sleep at night -- thanks not only to the conventions of the 9-to-5 workday, but also to the close interaction between our natural sleep and alertness rhythms, which are driven by an internal "clock." This clock is a small part of the brain called the suprachiasmatic nucleus of the hypothalamus. It sits just above the nerves leaving the back of our eyes. Light and exercise "reset" the clock and can move it forward or backward. Abnormalities related to this clock are called circadian rhythm disorders ("circa" means "about," and "dies" means "day"). Circadian rhythm disorders include jet lag, adjustments to shift work, delayed sleep phase syndrome (you fall asleep and wake up too late), and advanced sleep phase syndrome (you fall asleep and wake up too early).
A spermatocelectomy is surgery to remove a spermatocele. A spermatocele is a cyst (sac of fluid) that contains sperm. It forms inside your scrotum on the outside of your testicle. The cyst is most often attached to your epididymis. The epididymis is a tube that stores sperm.
