What is a Whipple procedure?
Also called a pancreaticoduodenectomy, the Whipple procedure is performed to address chronic pancreatitis and cancer of the pancreas, ampulla of Vater, duodenum, and the distal bile duct. The Whipple procedure involves removing the cancerous parts of the pancreas, duodenum, common bile duct, and if required, part of the stomach.
A semen analysis, also called "seminogram" evaluates certain characteristics of a male's semen and the sperm contained therein. It is done to help evaluate male fertility, whether for those seeking pregnancy or verifying the success of vasectomy
Purpose: To evaluate the results of LASIK and IntraLASIK treatment in myopic patients with nystagmus. Methods: Eight patients with congenital nystagmus (16 eyes), from 23 to 49 years of age, underwent LASIK surgery. Corneal flaps were created using either the Hansatome microkeratome or the Intral...ase femtosecond laser. The ablations were performed with the Bausch & Lomb excimer laser with an active tracking system. In some patients, the eyes were fixated with forceps or a fixation ring during the laser ablation. Results: The refractive errors were corrected in all cases. There was no decentration or loss of best corrected visual acuity greater than 1 line. In 56% of the eyes, the post-operative uncorrected visual acuity was better than the best spectacle corrected-visual acuity (BSCVA). 62.5% of the eyes improved their BSCVA. The overall visual performance was improved in all the patients. One patient that did not not drive before become eligible to get a driver license after the surgery. Conclusions: Selected patients with myopia and congenital nystagmus may benefit from laser refractive surgery. Laser refractive surgery may be safely and accurately performed by using either the Hansatome microkeratome or the Intralase femtosecond laser and an active tracking system with or without mechanical fixation. Certain patients improve their BSCVA post-operatively.
Multiple sclerosis (MS) is a potentially disabling disease of the brain and spinal cord (central nervous system). In MS, the immune system attacks the protective sheath (myelin) that covers nerve fibers and causes communication problems between your brain and the rest of your body. Eventually, the disease can cause the nerves themselves to deteriorate or become permanently damaged. Signs and symptoms of MS vary widely and depend on the amount of nerve damage and which nerves are affected. Some people with severe MS may lose the ability to walk independently or at all, while others may experience long periods of remission without any new symptoms. There's no cure for multiple sclerosis. However, treatments can help speed recovery from attacks, modify the course of the disease and manage symptoms
They might not sound very life threatening, but a blood clot that develops in the deep veins of your leg, if left untreated and unable to dissolve of its own volition, may detach and travel to your lungs, causing a pulmonary embolism (or PE). In most cases, a leg blood clot will form due to lengthy periods of travel, for example if you remain immobile in cramped spaces—such as an airplane or bus—with few opportunities to stretch your legs or get up and walk around. Here are ten signs that you may have a dangerous blood clot in your leg
If you’re like me, you probably hook your chest tube up to a Pleur-Evac, put it on the ground, then back away slowly. Who knows what goes on in that mysterious bubbling white box? Hopefully this will post shed some light. Isn’t this just a container for stuff that comes out of the chest? Why does it look so complicated? It’s complicated because the detection/collection of air and fluid require different setups. Most commercial models also allow you to hook the drainage system to wall suction, so you can quickly evacuate the pleural space. This requires its own setup. Because of the need to juggle air, fluid and suction, the most common commercial system includes 3 distinct chambers. If you were to simplify the device, or build one out of spare bottles and tubes, it might look like this:
