The Pulsed Electron Avalanche Knife, a new electrosurgical knife for “cold” and traction-less cutting, was successfully used for a variety of surgical maneuvers commonly encountered in patients undergoing ocular surgery.
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
Anterior vaginal wall relaxation (cystocele) is one of the most commonly diagnosed forms of pelvic organ prolapse in women. More than 200,000 cystocele repairs are completed yearly, however to date the procedures that are completed do not provide very high cure rates and/or poor anatomic outcomes. Successful treatment of anterior vaginal wall prolapse remains one of the most challenging aspects of pelvic reconstructive surgery we face. We have developed very good procedures that provide excellent support for the posterior wall (ie rectoceles) and the apex of the vagina (ie vaginal vault prolapse) and reproduce normal anatomy. We were one of the first centers in the country to utilize grafts in rectocele repairs and have seen improved cure rates to over 90% with minimal complications. It has been known for many years that abdominal sacralcolpopexy with placement of a mesh graft at the top of the vagina for vaginal vault prolapse is the most successful procedure in the literature. We have made advancements with this procedure as well in being able to offer our patients a laparoscopic minimally invasive approach for sacralcolpopexy, with the same excellent cure rates (>92%) and with hospital stays typically less than 24 hours and reduced complications. However the anterior wall has been one of the most difficult compartments in the vagina to get good anatomic results and high cure rates with traditional repairs and at the same time not cause sexual dysfunction, pain with intercourse, voiding dysfunction (ie incontinence or urgency/frequency syndrome), or a shortened or scarred down vagina. The transobturator approach was developed as a less invasive way to place an anterior wall graft (see below) however this still involved blind needle passes and the graft did not support the apex of the vagina, therefore the search for improvements in these procedures is ongoing.
In this video a real case of the extremely rare disease "Fibrodysplasia ossificans progressiva" or what is called the "FOP" This disease is commonly misdiagnosed and usually end up by unnecessary surgery which exaggerate the disease. Children born with FOP characteristically have deformed great toes, possibly missing a joint or simply presenting with a notable lump at the minor joint. The first "flare-up" that leads to the formation of FOP bones usually occurs before the age of 10. FOP is a genetic disease. The bone growth progresses from the top downward, just as bones grow in fetuses. A child with FOP will typically develop bones starting at the neck, then on the shoulders, arms, chest area and finally on the feet. However it does not necessarily occur in this order due to injury-caused flare-ups. Often, the tumor-like lumps that characterize the disease appear suddenly. The gene that causes ossification is normally deactivated after a fetus' bones are formed in the womb, but in patients with FOP, the gene keeps working. Aberrant bone formation in patients with FOP occurs when injured connective tissue or muscle cells at the sites of injury or growth incorrectly express an enzyme for bone repair during apoptosis (self-regulated cell death), resulting in lymphocytes containing excess bone morphogenetic protein 4 (BMP4) provided during the immune system response. Since the incorrect enzyme remains unresolved within the immune response, the body continues providing the incorrect BMP4-containing lymphocytes. BMP4 is a product that contributes to the development of the skeleton in the normal embryo.
