Dacryocystorhinostomy (DCR) is a procedure performed for the treatment of tearing (epiphora) due to blockage of the nasolacrimal duct. Tears originate in the lacrimal gland, located at the upper outer margin of the eye. As tears cross the eye with each blink, they are directed into small openings in the eyelids called puncta. From this point, tears travel through a pathway known as the canalicular system into the lacrimal sac. The lacrimal sac is located between the eye and the nose, and funnels tears into the nasal cavity through the nasolacrimal duct (Figure 1). As this is quite a long path for tears to travel, there can be many causes of excessive tearing. Blockage of the nasolacrimal duct is one common cause, and can be treated by creating a direct opening from the lacrimal sac into the nasal cavity in a procedure known as DCR. The evaluation and management of tearing may involve both an ophthalmologist and an otolaryngologist.
Multiple endocrine neoplasia type 2 (MEN2) (also known as "Pheochromocytoma and amyloid producing medullary thyroid carcinoma", "PTC syndrome," and "Sipple syndrome") is a group of medical disorders associated with tumors of the endocrine system. The tumors may be benign or malignant (cancer).
All forms of heparin (including low-molecular-weight heparin such as enoxaparin) must be stopped immediately in patients with suspected heparin-induced thrombocytopenia (HIT) while awaiting diagnostic confirmation. Patients with HIT remain at high risk of thrombosis even after discontinuation of heparin. Therefore, an alternate, rapidly acting, non-heparin anticoagulant such as direct thrombin inhibitor (eg, argatroban, bivalirudin) must be started immediately.
The "Get up and go" test is most commonly used to assess postural stability. In this test, the physician instructs the patient to stand up from a chair without assistance, walk a short distance, turn around, return, and sit down again. If the patient is unsteady or has difficulties during the test, further evaluation is necessary.

Preventing heart attacks and stroke can involve extensive surgery to remove plaque from your arteries, but as FOX17's Nick Paranjape shows us, there's a new procedure in Middle Tennessee that is less invasive and substantially cuts down on your recovery time. At 76, Jimmy Wilkie of Hendersonville exercises on his treadmill 3-4 times a week. Recently, he started having pain in his left leg. It was so bad, he couldn't even walk. Turned out, Mr. Wilkie had a blocked artery in his leg. In years past, this would've required major bypass surgery. Not anymore!"The Turbohawk Catheter has really opened a new door for us," says Dr. Dan Wunder.Dr. Wunder, an Interventional Radiologist at Premier Radiology in Madison, is talking about the Turbohawk. It's a device which is inserted into the blocked artery, and inside the Turbohawk are 4 tiny blades."It can cut the plaque and with that shape of the disc it cuts with it pushes it forward into the catheter," says Dr. Wunder.The one-hour procedure doesn't just push the plaque to the sides where it can re-grow, but instead grabs it and removes it!"We pull it back out and it fills up," says Dr. Wunder. "Empty it out, go back down and we can cut some more out."Before and after images really say it all."They used a roto rooter as he called it," says Wilkie.A roto rooter, Turbohawk, call it what you want, but Wilkie says all he knows is the procedure worked right away!"There wasn't any pain at all in my leg," says Wilkie.It's rare, but the outpatient procedure can have complications like plaque getting pushed down in the leg. Dr. Wunder says the main symptoms of a blockage in your legs is having severe pain or cramping when you're walking or exercising.
Knee replacement surgery advances are improving patients' experiences and outcomes. Knee surgery -- or even partial knee replacement -- is often the solution for advanced knee arthritis. Today you can regain significant mobility and flexibility after knee replacement thanks to advances in orthopedic surgery technology, materials and techniques. Knee replacement recovery times also have improved. This knee replacement surgery video covers what you can expect out of these knee joint replacement advances. Knee replacement surgery has been around for more than 30 years and is an incredibly successful operation. In the past the past, when a person had bad arthritis of the knee, they were pretty much out of luck other than taking aspirin. They'd be debilitated and limited in their activities. So, when a person has pain, stiffness, and their life is becoming restricted by that, that's when it's time to consider knee replacement. We always do non-surgical treatment first. When that doesn't work anymore, then it's time to consider knee replacement. About 500,000 a year are done, and most patients who have gone through this basically say that they wish they had done it sooner.
Is Air Travel During Pregnancy Safe? Traveling by air is considered safe for women while they are pregnant; however, the following ideas might make your trip safer and more comfortable. Most airlines allow pregnant women to travel through their eighth month.
Disc Disease Videos Watch Disc Disease Videos There are several symptoms that are fairly consistent for people with lower back pain or neck pain from degenerative disc disease, including: Pain that is usually related to activity and will flare up at times but then return to a low-grade pain level, or the pain will go away entirely The amount of chronic pain—referred to as the patient's baseline level of pain—is quite variable between individuals and can range from almost no pain/just a nagging level of irritation, to severe and disabling pain Severe episodes of back or neck pain that will generally last from a few days to a few months before returning to the individual's baseline level of chronic pain Chronic pain that is completely disabling from degenerative disc disease does happen in some cases, but is relatively rare See Treating Chronic Pain and Depression from Degenerative Disc Disease
ARDS was recognized as the most severe form of acute lung injury (ALI), a form of diffuse alveolar injury. The AECC defined ARDS as an acute condition characterized by bilateral pulmonary infiltrates and severe hypoxemia in the absence of evidence for cardiogenic pulmonary edema. The severity of hypoxemia necessary to make the diagnosis of ARDS was defined by the ratio of the partial pressure of oxygen in the patient’s arterial blood (PaO2) to the fraction of oxygen in the inspired air (FiO2). ARDS was defined by a PaO2/FiO2 ratio of less than 200, and in ALI, less than 300. This definition was further refined in 2011 by a panel of experts and is termed the Berlin definition of ARDS. [3] ARDS is defined by timing (within 1 wk of clinical insult or onset of respiratory symptoms); radiographic changes (bilateral opacities not fully explained by effusions, consolidation, or atelectasis); origin of edema (not fully explained by cardiac failure or fluid overload); and severity based on the PaO2/FiO2 ratio on 5 cm of continuous positive airway pressure (CPAP). The 3 categories are mild (PaO2/FiO2 200-300), moderate (PaO2/FiO2 100-200), and severe (PaO2/FiO2 ≤100).
