What is vascular access? What are the different types of accesses for hemodialysis? Does vascular access require surgery? Adina Voiculescu, M.D., FASDIN, General and Interventional Nephrologist at Brigham and Women's Hospital and Assistant Professor at Harvard Medical School, discusses the different types of vascular access, such as AV fistulas and AV grafts, and how to stay healthy while on hemodialysis.

Peptic ulcers are open sores that develop on the inside lining of your stomach and the upper portion of your small intestine. The most common symptom of a peptic ulcer is stomach pain. Peptic ulcers include: Gastric ulcers that occur on the inside of the stomach Duodenal ulcers that occur on the inside of the upper portion of your small intestine (duodenum) The most common causes of peptic ulcers are infection with the bacterium Helicobacter pylori (H. pylori) and long-term use of aspirin and certain other painkillers, such as ibuprofen (Advil, Motrin, others) and naproxen sodium (Aleve, Anaprox, others). Stress and spicy foods do not cause peptic ulcers. However, they can make your symptoms worse.

A natural, unmedicated approach to labor and birth will suit you best if you want to remain in control of your body as much as possible, be an active participant throughout labor, and have minimal routine interventions such as continuous electronic monitoring. If you choose to go this route, you accept the potential for pain and discomfort as part of giving birth. But with the right preparation and support, women often feel empowered and deeply satisfied by natural childbirth.

Dr. Debbie Song at Gillette Children's describes in detail selective rhizotomy surgery.

A selective dorsal rhizotomy is an operation performed to treat spasticity. It is thought that high tone and spasticity arise from abnormal signals that are transmitted through sensory or dorsal nerve roots to the spinal cord. In a selective dorsal rhizotomy we identify and cut portions of the dorsal nerve roots that carry abnormal signals thereby disrupting the mechanisms that lead to spasticity. Potential patients go through a rigorous assessment that includes an in-depth gait and motion analysis as well as a physical therapy evaluation.

They are evaluated by a multidisciplinary team that includes a pediatric rehabilitation doctor, a neurosurgeon, and an orthopedist, Appropriate patient selection is vital. Ideal candidates for selective dorsal rhizotomy are children who are between four and ten years of age, have a history of being born prematurely, and have a diagnosis of diplegia cerebral palsy. These patients usually walk independently or with the assistance of crutches or a walker. They typically function at a level one, two, or three in the gross motor function classification system or gmfcs. A selective dorsal rhizotomy involves the coordinated efforts of the neurosurgery, physiatry, anesthesia and nursing teams. The operation entails making an incision in the lower back that is approximately six to eight inches long. We perform what we call a laminoplasty in which we remove the back part of the spinal elements from the lumbar one or l1 to l5 levels. At the end of the procedure the bone is put back on. We identify and open up the Dural sac that contain the spinal fluid spinal cord and nerve roots. Once the Dural sac is opened ,we expose the lumbar and upper sacral nerve roots that transmit information to and from the muscles of the lower extremities.

At each level we isolate the dorsal nerve root, which in turn is separated into as many as 30 smaller thread light fruitlets.

Each rootlet is then electrically stimulated. Specialized members of the physiatry team look for abnormal responses in the muscles of the legs as each rootless is being stimulated. If an abnormal response is observed then the rootlet is cut.

If a normal response is observed, then the rootlet is not cut. We usually end up cutting approximately 20 to 40 percent of the rootlets. The Dural sac is sutured closed and the l1 through l5 spinal elements are put back into anatomic position, thus restoring normal spinal alignment. The overlying tissues and skin are then closed and the patient is awoken from surgery. The entire operation takes between four and five hours. A crucial component to the success of our rhizotomy program is the extensive rehabilitation course following surgery. With their tone significantly reduced after a rhizotomy, patients relearn how to use their muscles to walk more efficiently through stretching, strengthening, and gait training. Approximately one to two years after a rhizotomy patients undergo repeat gait and motion analysis. The orthopedic surgeons assess the need for interventions to correct bone deformities, muscle contractures, poor motor control, impaired balance, or other problems related to cerebral palsy.

At Gillette we work closely with patients and families to ensure that our selective dorsal rhizotomy program meets their goals for enhancing their function and improving their quality of life.

Renal artery stenosis is a narrowing of arteries that carry blood to one or both of the kidneys. Most often seen in older people with atherosclerosis (hardening of the arteries), renal artery stenosis can worsen over time and often leads to hypertension (high blood pressure) and kidney damage.
