The cardiac conduction system is a group of specialized cardiac muscle cells in the walls of the heart that send signals to the heart muscle causing it to contract. The main components of the cardiac conduction system are the SA node, AV node, bundle of His, bundle branches, and Purkinje fibers.

Small cell lung cancer, which occurs almost exclusively in smokers, is a malignancy characterised by rapid doubling time, high growth fraction and widespread metastasis at presentation. In this presentation, we will briefly discuss the classification of pulmonary Neuro-endocrine tumours by the World Health Organisation followed by a detailed discussion of the clinical features, lab evaluation and management of SCLC, both limited and extended stage. The frontline therapy in small cell lung cancer is etoposide and cisplatin along with thoracic radiotherapy and prophylactic cranial irradiation in patients who have a good response to therapy. Hyperfractionation of radiotherapy may provide some benefit but is also associated with increase incidence of complications. Newer agents for SCLC include Vandetanib and immunotherapy molecules, such as Iplimumab and nivolumab.
Watch this video to learn how and when to change a dressing for a child with a hemodialysis catheter. You should change your child's dressing if it becomes soiled with water or blood or if it comes off at home. Keeping a clean dressing on your child will limit risk of infection.
Colon polyp facts Colon polyps are growths on the inner lining of the colon and are very common. Colon polyps are important because they may be, or may become malignant (cancerous). They also are important because based on their size, number, and microscopic anatomy (histology); they can predict which patients are more likely to develop more polyps and colon cancer. Changes in the genetic material of cells lining the colon are the cause of polyps. There are different types of colon polyps with differing tendencies to become malignant and abilities to predict the development of more polyps and cancer. It is important to recognize families with members who have familial genetic conditions causing polyps because some of these conditions are associated with a very high incidence of colon cancer, and the cancer can be prevented or discovered early.

If your kidney function is declining and medications and other treatments aren’t working, dialysis can offer life-saving care. UVA has one of the largest dialysis programs in the country. Nephrologist Daphne Knicely, MD, explains the types of home dialysis and how they can work to fit your life.

Dialysis is just a way to replace the kidneys when they're not working anymore. So when the kidneys stop working, they stop getting rid of water, stop balancing the chemistry, stop getting rid of the toxins. Then dialysis does its job by balancing the chemistries, getting rid of the toxins, and help remove fluid. It doesn't fix the kidneys. It just replaces them.
I usually think of dialysis as two components. There's hemodialysis and peritoneal dialysis. So peritoneal dialysis can only be done at home. Hemodialysis can be done in a center, or it can be done at home.
Hemodialysis is where you have some sort of access to the blood. Either some sort of shunt in the arm that connects an artery and vein, or a catheter. And it allows for blood to leave you, go through a machine, get cleaned, chemistries balanced, and then comes back to you.
For home hemodialysis, the patient actually learns how to do that treatment. It's a very simple machine, very user-friendly. Training is usually about anywhere from four weeks up to eight weeks, and you work one-on-one with a nurse. You still see the physician. You come in about once a month, maybe twice a month, to get labs. You'll see a social worker, and a nutritionist at the same time.
Peritoneal dialysis takes place by putting a tube into your abdomen. And we take dialysis fluid that's chemically balanced. When we put it into the abdomen, it uses those little blood vessels to pull toxins out, to balance chemistries, kind of like little filters. Now, after it sits in there for several hours, we drain it out.
Anyone that needs dialysis is a candidate for home dialysis. There's not one type of dialysis that's going to make you live longer. They're all equal. The goal is to pick the type of dialysis that fits with your life.
Macrobiopsy of breast lesions is a complicated procedure when performed with vacuum assisted biopsy tools. The Spirotome is a hand-held needle set that doesn't need capital investment, is ready to use and provides tissue samples of high quality in substantial amounts. In this way quantitative molecular biology is possible with one tissue sample. The Coramate is an automated version of this direct and frontal technology.
