Cartilage is a slippery tissue that provides a smooth surface for joint motion and acts as a cushion between the bones. Synovium is soft, and it lines the joints. It produces fluid, called synovial fluid, for lubrication, and it supplies nutrients and oxygen to the cartilage. As these functions break down, they no longer protect the bones of the knee joint, and bone damage occurs. OA of the knee can cause pain and stiffness. The symptoms worsen over time
Mysterious things happen in nature, and extraordinary birth delivery facts amaze and astound us. And "The baby who didn't know he was born" is one of them; the reason was because his mother didn't break water, so the little one thought was still in the womb. Of course, the amniotic sac was later broken by the doctor, and as soon as this happened the baby began to breath and cry.
LASIK eye surgery is commonly performed laser refractive surgery to correct vision problems. This 3d animation shows how laser-assisted in situ keratomileusis (lasik) can be an alternative to glasses or contact lenses.
It’s one of many vision correction surgeries that work by reshaping your cornea, the clear front part of your eye, so that light focuses on the retina in the back of your eye.
In eyes with normal vision, the cornea bends (refracts) light precisely onto the retina at the back of the eye. But with nearsightedness (myopia), farsightedness (hyperopia) or astigmatism, the light is bent incorrectly, resulting in blurred vision.
During LASIK surgery, a special type of cutting laser is used to precisely change the shape of the dome-shaped clear tissue at the front of your eyes (cornea) to improve vision.
Glasses or contact lenses can correct vision, but reshaping the cornea itself also will provide the necessary refraction.

Ureteral stents are one of the most common devices used by urologists. They are placed with cystoscopic guidance in an operating room setting. Ureteral stents are used to relieve ureteral obstruction, promote ureteral healing following surgery, and to assist with ureteral identification during pelvic surgery. Ureteral stent placement is associated with some degree of morbidity in the majority of patients that ranges from generalized urinary discomfort to urinary tract infection or obstruction. Much of the morbidity is related to the biocompatibility of the materials used to fashion the stent and, to some extent, their design; unfortunately, the ideal stent has yet to be discovered.
The goal of surgical clipping is to isolate an aneurysm from the normal circulation without blocking off any small perforating arteries nearby. Under general anesthesia, an opening is made in the skull, called a craniotomy. The brain is gently retracted to locate the aneurysm. A small clip is placed across the base, or neck, of the aneurysm to block the normal blood flow from entering. The clip works like a tiny coil-spring clothespin, in which the blades of the clip remain tightly closed until pressure is applied to open the blades. Clips are made of titanium and remain on the artery permanently.
In this medical video: This 72-year-old patient was unable to resist blinking when we tapped on the glabella. This is the glabellar reflex or Myerson's sign . It is often an early sign of Parkinson's disease, but can also be seen in early dementia as well as other progressive neurologic illness. Note the left (i.e., asymmetrical) hand resting tremor.
Empyema can develop after you have pneumonia. Many different types of bacteria may cause pneumonia, but the two most common are Streptococcus pneumoniae and Staphylococcus aureus. Occasionally, empyema may happen after you've had surgery on your chest. Medical instruments can transfer bacteria into your pleural cavity
Wolff-Parkinson-White (WPW) syndrome, an extra electrical pathway between your heart's upper and lower chambers causes a rapid heartbeat. The extra pathway is present at birth and fairly rare. The episodes of fast heartbeats usually aren't life-threatening, but serious heart problems can occur. Treatment can stop or prevent episodes of fast heartbeats. A catheter-based procedure (ablation) can permanently correct the heart rhythm problems. Most people with an extra electrical pathway experience no fast heartbeat. This condition, called Wolff-Parkinson-White pattern, is discovered only by chance during a heart exam. Although WPW pattern is often harmless, doctors might recommend further evaluation before children with WPW pattern participate in high-intensity sports.
