A brief description of the mechanisms, types and assessment of chromosomal analyses. Techniques such as standard cytogenetic testing, FISH and array methods are discussed. Indications for testing in prenatal, neonatal and adult periods are also discussed. Deletions, translocations, inversions etc are described, as are mosaicism and aneuploidy.
Scientists don't know what causes canker sores. Most believe that there is a problem with the body's immune system. Emotional stress, menstruation or injury to the mouth are common triggers for simple canker sores. Certain foods such as citrus or acidic foods may trigger a canker sore or make one more uncomfortable.
Superior capsule reconstruction (SCR) is a promising alternative treatment for irreparable posterosuperior rotator cuff tears (Figure 1). It utilizes a graft from the superior glenoid to the greater tuberosity to stabilize the humeral head. In a study by Mihata and colleagues of 23 patients who underwent SCR with a fascia lata autograft at a minimum of 2 years follow-up, the American Shoulder and Elbow Surgeons (ASES) score improved significantly from 23.5 preoperatively to 92.9. Postoperative MRI showed 83% of patients had intact reconstructions with no progression of muscle atrophy.
A Fistulotomy is the surgical opening or removal of a fistulous tract. They can be performed by excision of the tract and surrounding tissue, simple division of the tract, or gradual division and assisted drainage of the tract by means of a seton; a cord passed through the tract in a loop which is slowly tightened over a period of days or weeks.
Fistulas can occur in various areas of the human body, and the location of the fistula influences the necessity of the procedure. Some, such as ano-vaginal and perianal fistulas are chronic conditions, and will never heal without surgical intervention.
During the examination, the doctor gently puts a lubricated, gloved finger of one hand into the rectum. He or she may use the other hand to press on the lower belly or pelvic area. A digital rectal exam is done for men as part of a complete physical examination to check the prostate gland .
Our General Surgery team treats hernia patients on a daily basis. In fact, you could consider them to be hernia experts. We sat down with one of those experts, Dr. Heater Dunlap, to talk about the common signs and symptoms of hernias and to answer the question of when to see a doctor.
Dr. Ailawadi, M.D., the Chair of Cardiac Surgery at Michigan Medicine, specializes in minimally invasive valve surgery as well as complex cardiac operations. This video shows step by step footage of a Coronary Artery Bypass Graft (CABG) in a complex patient. In this case, CABG was performed through a sternotomy (through the breast bone) using the internal thoracic artery and saphenous leg veins to bypass obstructed coronary arteries. In this video, Dr. Ailawadi will perform a triple vessel bypass (CABG) which has been shown to minimize the risk of future heart attack and help patients live longer in the setting of complex coronary artery disease.

A pancreas transplant is a surgical procedure to place a healthy pancreas from a deceased donor into a person whose pancreas no longer functions properly. Your pancreas is an organ that lies behind the lower part of your stomach. One of its main functions is to make insulin, a hormone that regulates the absorption of sugar (glucose) into your cells. If your pancreas doesn't make enough insulin, blood sugar levels can rise to unhealthy levels, resulting in type 1 diabetes. Most pancreas transplants are done to treat type 1 diabetes. A pancreas transplant offers a potential cure for this condition. But it is typically reserved for those with serious diabetes complications, because the side effects of a pancreas transplant are significant. In some cases, pancreas transplants may also treat type 2 diabetes. Rarely, pancreas transplants may be used in the treatment of pancreatic, bile duct or other cancers. A pancreas transplant is often done in conjunction with a kidney transplant in people whose kidneys have been damaged by diabetes.
