Dialysis patients need to choose their heart medicine carefully, as Canadian researchers say that some beta blockers are easily removed from the blood during treatment. Also, people who eat a Mediterranean diet may decrease their risk of developing kidney problems. Eboni Williams reports on the day's top health news.

[GRAPHIC CONTENT WARNING: Images of a Surgical Procedure]

In 2011, our doctors performed more than 880 open-heart surgeries and 6,100 catheter-based procedures, including nearly 2,000 angioplasties. MedStar Union Memorial performs a higher percentage (94 percent) of beating-heart bypass surgeries than any other hospital in the nation.

Vanderbilt Medical Center neurosurgeons and neurologists will be online demonstrating their 4-stage innovative technique used for Deep Brain Stimulation (DBS). Deep brain stimulation therapy utilizes an implantable neuro-stimulator to treat movement disorders such as Parkinson's disease, essential tremor, and dystonia.

Descemet’s stripping automated endothelial keratoplasty (DSAEK) avoids a full-thickness corneal procedure and provides rapid visual rehabilitation. Successful graft positioning while minimizing intraoperative donor endothelial trauma may determine long-term graft survival. Previously described t...echniques for graft insertion may be problematic in some patients with intraoperative floppy iris syndrome (IFIS), anatomically shallow or unstable anterior chambers, or intraoperative increased posterior pressure. This video displays alternative method called the suture drag technique, which may facilitate lamellar endothelial graft insertion under these special circumstances.

New treaments for psoriasis include Remicade, which blocks TNF- tumor necrosis factor, alpha.

In PRK the epithelium (top layer of the cornea) is scraped off and then the laser treatment is applied. A contact lens is used as a "bandage" to decrease discomfort. The epithelium then grows back over the bare area during the next few days.

In LASEK the epithelium is exposed to 20% alcohol which helps separate epithelium from the cornea. The epithelium is pushed to one side and laser treatment applied. The epithelial layer is replaced back onto the eye and held in place with a contact lens. The contact lens is then removed a few days later. LASEK is hence a "no knife"/flap operation.

Epi-Lasik is a similar procedure that uses a keratome like that used for Lasik, but engineered to only separate the epithelium. The epithelium is left on a hinge, laser treatment applied and flap replaced.

A revision knee replacement operation is shown in four parts. In this first part, an account of the patient is given on why he wanted a revision. This patient was dissatisfied with the range of movement that he got after a primary TKR. The first part shows the exposure and removal of the old implants. From www.kneeindia.com
