Before Dr. Benjamin Carson became the first person to successfully separate twins conjoined at the head, before he had a TV movie made about his life, before he became known for his "gifted hands" and before he became head of pediatric neurosurgery at Johns Hopkins, Ben Carson was headed down the wrong path in life.
Liddle syndrome is an inherited form of high blood pressure (hypertension). This condition is characterized by severe hypertension that begins unusually early in life, often in childhood, although some affected individuals are not diagnosed until adulthood. Some people with Liddle syndrome have no additional signs or symptoms, especially in childhood. Over time, however, untreated hypertension can lead to heart disease or stroke, which may be fatal.
This video: Blisters caused by friction or minor burns do not require a doctor's care. New skin will form underneath the affected area and the fluid is simply absorbed. Do not puncture a blister unless it is large, painful, or likely to be further irritated. The fluid-filled blister keeps the underlying skin clean, which prevents infection and promotes healing.

The kidneys are a pair of organs located in the back of the abdomen. Each kidney is about 4 or 5 inches long -- about the size of a fist. The kidneys' function are to filter the blood. All the blood in our bodies passes through the kidneys several times a day. The kidneys remove wastes, control the body's fluid balance, and regulate the balance of electrolytes. As the kidneys filter blood, they create urine, which collects in the kidneys' pelvis -- funnel-shaped structures that drain down tubes called ureters to the bladder. Each kidney contains around a million units called nephrons, each of which is a microscopic filter for blood. It's possible to lose as much as 90% of kidney function without experiencing any symptoms or problems.
Atrial Fibrillation is the most common heart rythmn abnormatlity and is very common as you age. Atrial fibrillation is a condition in which the top chambers of the heart, the Atrium are fibrillating, rather than having a regular synchronized contraction.

Sciatica is often characterized by one or more of the following symptoms: Constant pain in only one side of the buttock or leg (rarely in both legs) Pain that is worse when sitting Leg pain that is often described as burning, tingling, or searing (versus a dull ache) Weakness, numbness, or difficulty moving the leg, foot, and/or toes A sharp pain that may make it difficult to stand up or walk Pain that radiates down the leg and possibly into the foot and toes (it rarely occurs only in the foot) Sciatica Causes and Treatments Video Watch: Sciatica Causes and Treatments Video Sciatic pain can vary from infrequent and irritating to constant and incapacitating. Symptoms are usually based on the location of the pinched nerve. While symptoms can be painful and potentially debilitating, it is rare that permanent sciatic nerve damage (tissue damage) will result, and spinal cord involvement is possible but rare.
Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used to get vascular access in trauma and hypovolemic shock patients when peripheral cannulation is difficult or impossible
Plasma cell dyscrasias are disorders of the plasma cells. Plasma cell dyscrasias are produced as a result of abnormal proliferation of a monoclonal population of plasma cells that may or may not secrete detectable levels of a monoclonal immunoglobulin or immunoglobulin fragment (paraprotein or M protein).
Intramedullary nailing of the tibia with suprapatellar entry and semi-extended positioning makes it technically easier to nail the proximal and distal fractures. The purpose of this article was to describe a simple method for suprapatellar nailing (SPN). A step-by-step run through of the surgical technique is described, including positioning of the patient. There are as yet only a few clinical studies that illustrate the complications with this method, and there has been no increased frequency of intraarticular damage. Within the body of the manuscript, information is included about intraarticular damage and comments with references about anterior knee pain.
Chronic obstructive pulmonary disease (COPD) is defined as progressive, chronic airflow obstruction due to chronic bronchitis, emphysema, or both. The majority of patients have components of both, although one of these entities will frequently dominate the clinical picture. Emphysema�airspace enlargement distal to the terminal bronchioles due to destruction of alveolar septa. Chronic bronchitis�chronic airway inflammation and bronchospasm. Clinically defined as productive cough lasting for at least 3 mo over 2 consecutive years. Although COPD is irreversible, patients with acute exacerbations do have reversible bronchospastic and inflammatory components.
