mply put, relapses, also known as flare ups, or (MS) attacks are new or worsening MS symptoms. But there is a concrete definition used by healthcare providers to identify MS attacks. To be considered an MS relapse: Old symptoms of MS must have become worse or new symptoms appeared.
This animated video is an informative video that provides information regarding Upper Gastro-intestinal Endoscopy. An upper GI endoscopy procedure allows your doctor to view the mucus lining of the upper portion of your gastro-intestinal tract. This includes your oesophagus, stomach and duodenum. Upper endoscopy is used to evaluate symptoms of persistent upper abdominal pain, nausea, vomiting, bleeding, or difficulty in swallowing. The procedure is performed using an endoscope which is a long thin flexible tube a light and a tiny video camera attached to the end. The camera transmits the image to a monitor. Uncomplicated upper endoscopy takes 10-20 minutes, your doctor will gently insert the endoscope through your mouth and then slowly and carefully move it down your oesophagus until it reaches your stomach. An endoscopy for stomach may also be necessary in some cases.
Dilation and curettage (D&C) is a procedure to remove tissue from inside your uterus. Doctors perform dilation and curettage to diagnose and treat certain uterine conditions — such as heavy bleeding — or to clear the uterine lining after a miscarriage or abortion. In a dilation and curettage — sometimes spelled "dilatation" and curettage — your doctor uses small instruments or a medication to open (dilate) your cervix — the lower, narrow part of your uterus. Your doctor then uses a surgical instrument called a curette to remove uterine tissue. Curettes used in a D&C can be sharp or use suction

LASIK, or "laser-assisted in situ keratomileusis," is the most commonly performed laser eye surgery to treat myopia, hyperopia and astigmatism. The goal of the treatment is to reshape the cornea to correct the refractive error of the eye.
The cornea is the transparent dome-shaped structure in front of the eye. The cornea refracts light and accounts for about two-thirds of the eye's total optical power. Altering the curvature of the cornea changes the way light rays enter the eye. As a result, the light rays can be focused properly onto the retina for clearer vision.
For nearsighted people, the laser is used to flatten the cornea. For farsighted people, the cornea is made steeper. For patients with astigmatism, the laser is used to smooth the irregularly-shaped cornea into a more regular shape.
The outer layer of the cornea - the epithelium – is capable of replacing itself within a few days after being damaged or removed. The deeper layer of the cornea – the stroma, on the contrary, is a permanent corneal tissue with very limited regenerative capacity. The stroma, if reshaped by a laser, will remain that way permanently.
In this procedure, a thin, circular "FLAP" is created in the surface of the cornea to gain access to the permanent corneal tissue. This can be done with a mechanical cutting tool called a microkeratome, OR, for a blade-free experience, by a femtosecond laser. An excimer laser is then used to remove some corneal tissue to reshape the cornea. Excimer laser uses cool ultraviolet light beams to vaporize microscopic amounts of tissue in a precise manner to accurately reshape the cornea. The excimer laser is computer-controlled and is programmed based on the patient’s refractive error. The flap is then laid back in place and is allowed to heal.
LASIK eye surgery is mostly painless and can be completed within minutes. Improved vision can usually be seen overnight.
PRK, or photorefractive keratectomy, was the first type of laser eye surgery for vision correction and is the predecessor to the popular LASIK procedure. In PRK, NO flap is created. Rather, the epithelial cells on the eye surface are simply removed. An excimer laser is then used to reshape the cornea just like it does in LASIK.
The vision correction outcomes of PRK surgery are comparable to those of LASIK, but the recovery period is longer. This is because the epithelium is completely removed in PRK and it takes a few days to regenerate. PRK patients also have more discomfort and haziness of vision in the first few days after the surgery. Improved vision also takes longer to achieve.
PRK does, however, offer certain advantages. Because PRK does not involve creation of a flap, which contains both epithelial and deeper stromal tissue, the entire thickness of the stroma is available for treatment. The treatment range is therefore higher. This is particularly useful for patients with high levels of myopia or for those whose cornea is too thin for LASIK. PRK is also free of flap-related complication risks.
A Pap smear (Papanicolau smear; also known as the Pap test) is a screening test for cervical cancer. The test itself involves collection of a sample of cells from a woman's cervix (the end of the uterus that extends into the vagina) during a routine pelvic exam
Maintaining sufficient blood flow to the gastric tube after a subtotal esophagectomy for esophageal cancer is crucial for decreasing the esophagogastric anastomotic leakage. After subtotal esophagectomy for esophageal cancer, to additionally revascularize the gastric tube using the splenic artery a...nd vein, external carotid artery, and internal jugular vein, the supercharge technique was performed in esophageal reconstruction patients. Operative results of these patients (supercharge group) were retrospectively compared with those of patients not receiving the technique (control group). Both operation time and operative blood loss in the supercharge group were significantly longer and larger than those of the control group. However, the incidence of anastomotic leakage was significantly lower in the supercharge group than in the control group, and a 30-day reduction in the mean postoperative hospital stay was achieved with the supercharge group. This practical supercharge technique could be a breakthrough less to reduce leakage during esophageal anastomosis.
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.
