Yannas had been studying collagen, a protein found in human skin. Teaming up during the 1970s, the two made a polymer (a chemical compound made of multiple repeating units). Using collagen fibers and a long sugar molecule, they formed a porous (full of small holes) material resembling skin.

This procedure describes one of the most versatile approaches to the anterior skull base for large tumors of the sinonasal cavity. It may be used with or without a craniofacial resection. The benefits of this approach are: wide access around the tumor; good postoperative cosmesis; & decreased operative & postoperative morbidity. We have used this approach for many bilateral tumors of the nasal & sinus cavities that approach &/or invade the skull base & brain. This video show the resection of a large esthesioneuroblastoma.

Minimally Invasive Surgery (MIS) Hip Joint Replacement is an advancement in hip replacement that offers important advantages over standard surgical procedures. Stryker has partnered with surgeons worldwide to develop MIS procedures and surgical instruments that are designed to help your surgeons do their very best to help you recover your lifestyle. These techniques bring together a wide variety of hip implants, new minimally invasive surgical techniques, and new instrumentation. The direct anterior approach is one of the minimally invasive techniques used in hip replacement surgery. Continuing orthopaedic experience suggests that this procedure may offer several advantages over the more traditional surgical approaches to hip replacement.1 Traditional hip replacement techniques involve operating from the side (lateral) or the back (posterior) of the hip, which requires a significant disturbance of the joint and connecting tissues and an incision approximately 8-12 inches long. In comparison, the direct anterior approach requires an incision that is only 3-4 inches in length and located at the front of the hip.1 In this position, the surgeon does not need to detach any of the muscles or tendons.

PARAPHARYNGEAL SPACE TUMORS: SURGICAL APPROACH

Simple microinstruments and a medical school laboratory microscope were used for anastomosis training. Chicken blood vessels were used as a material for this study. A long segment of blood vessel from the proximal brachial artery to the distal radial artery was used for training. End-to-side anastomosis was practiced first, and the training continued with end-to-end anastomosis of the appropriate segments.

The procedure was performed under wrist block regional anesthesia with tourniquet control. A single Chinese finger trap was used on the thumb with 5 to 8 lb of ongitudinal traction. The arm was held down with wide tape around the tourniquet securing it to the hand table to serve as countertraction. A shoulder holder, rather than a traction tower, was used to facilitate fluoroscopic intervention more easily. The Trapeziometacarpal joint was detected by palpation. Joint distension was achieved by injecting 1 to 3 mL of normal saline (Fig. 1). It is important to distally direct the needle approximately 20 degrees to clear the dorsal flare of the metacarpal base and enter the joint capsule. This course should be reproduced upon entering with arthroscopic sleeve/ trocar assembly to minimize iatrogenic cartilage injury. Fluid distention is important to facilitate this. The incision for the 1-R (radial) portal, used for proper assessment of the dorsoradial ligament, posterior oblique ligament, and ulnar collateral ligament, was placed just volar to the abductor pollicis longus tendon. The incision for the 1-U (ulnar) portal, for better evaluation of the anterior oblique ligament and ulnar collateral ligament, was made just ulnar to the extensor pollicis brevis tendon. A short-barrel, 1.9-mm, 30- degree inclination arthroscope was used for complete visualization of the CMC joint surfaces, capsule, and ligaments, and then appropriate management was done, as dictated by the stage of the arthritis detected (Fig. 2A). A full-radius mechanical shaver with suction was used in all the cases, particularly for initial debridement and visualization. Most of the cases were augmented with radiofrequency ablation to perform a thorough synovectomy and radiofrequency was also used to perform chondroplasty in the cases with focal articular cartilage wear or fibrillation. Chondroplasty refers to thedebridement of the fibrillated cartilage to improve vascularity of the cartilage and enhance the growth of fibrocartilage. Ligamentous laxity and capsular attenu- ation were treated with thermal capsulorraphy using a radiofrequency shrinkage probe. We were careful to avoid thermal necrosis; hence, a striping technique was used to tighten the capsule of the lax joints. The striping technique refers to thermal shrinkage performed in longitudinal stripes on the lax capsule, so as to leave vascular zones between the stripes; hence, thermal necrosis is prevented. Arthroscopic stage I disease was characterized by synovitis without any cartilage wear, wherein a synovectomy coupled with thermal capsulor- raphy as described was performed.

Scientists have developed a wireless brain implant that enabled a paralyzed monkey to walk again.

The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract).

This video discusses knee arthritis, and when to do osteotomy, partial knee replacement, or total knee replacement.

Most of us have taken a sex education class or two. We know what condoms are supposed to be used for. Whether or not people use condoms every time they are necessary is a totally different story. You were probably taught the necessary but embarrassing lesson of how to put a condom on by the visual aids your sex education teacher provided. Of course, these tactics are a little more modern, so depending on how old you are, you may not have learned the basics of condom use until after high school. Yes, condoms are a pretty smart invention and they’re pretty safe to use. They are over 90% effective against sexually transmitted diseases (STDs), and of course, they help to reduce the risk of pregnancy by 98%. Some guys claim that they’re not comfortable to wear, which is why some companies have come up with new condoms that have a more natural fit and provide pleasure for both partners. However, with all the things we know about condoms, there’s still so much we don’t know. Here are 10 facts about condoms that are just as interesting as the condoms themselves.

The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions. First, for those impatient, short answers to the mini-questions (if you're reading this in the news feed, you may want to click through for the question details): No one knows why we evolved 2 kidneys and one liver.

How amblyopia develops in children. Basically, if one eye doesn't see well from an early age, the wiring never forms correctly back to the occipital cortex.

On Tuesday May 29th at 3:00pm EDT, University Hospitals Case Medical Center Cleveland, Ohio, will host a live webcast to demonstrate the removal of brain tumor and epileptic focus from an awake patient using intra-operative MRI and brain mapping. See this on OR-Live.com

The patient was a middle-aged gentleman with new onset seizures. An MRI showed what appeared to be a low grade glioma near the motor strip on the right. Studies have shown that complete removal can cure the seizures, improve quality of life and survival, but this is difficult to do with conventional technology without harming the surrounding normal brain because its difficult to determine where tumor ends and normal brain begins.

If you have gestational diabetes, your baby may be at increased risk of: Excessive birth weight. Extra glucose in your bloodstream crosses the placenta, which triggers your baby's pancreas to make extra insulin. This can cause your baby to grow too large (macrosomia).

An estimated 900,000 knee replacements are performed in the U.S. every year, but experts say about 15% of patients aren’t totally pleased with the outcome. An advancement in technology is focused on improving those outcomes.
