Atopic dermatitis (eczema) is a condition that makes your skin red and itchy. It's common in children but can occur at any age. Atopic dermatitis is long lasting (chronic) and tends to flare periodically and then subside. It may be accompanied by asthma or hay fever.

The bones, ligaments and tendons that make up your shoulder joint are encased in a capsule of connective tissue. Frozen shoulder occurs when this capsule thickens and tightens around the shoulder joint, restricting its movement. Doctors aren't sure why this happens to some people, although it's more likely to occur in people who have diabetes or those who recently had to immobilize their shoulder for a long period, such as after surgery or an arm fracture.

Electrophysiology studies test the electrical activity of your heart to find where an arrhythmia (abnormal heartbeat) is coming from. These results can help you and your doctor decide whether you need medicine, a pacemaker, an implantable cardioverter defibrillator (ICD), cardiac ablation or surgery.

Catheter ablation is a minimally invasive procedure to treat atrial fibrillation. It can relieve symptoms and improve quality of life. During an ablation, the doctor destroys tiny areas in the heart that are firing off abnormal electrical impulses and causing atrial fibrillation. You will be given medicine to help you relax. A local anesthetic will numb the site where the catheter is inserted. Sometimes, general anesthesia is used. The procedure is done in a hospital where you can be watched carefully. Thin, flexible wires called catheters are inserted into a vein, typically in the groin or neck, and threaded up into the heart. There is an electrode at the tip of the wires. The electrode sends out radio waves that create heat. This heat destroys the heart tissue that causes atrial fibrillation or the heart tissue that keeps it happening. Another option is to use freezing cold to destroy the heart tissue. Sometimes, abnormal impulses come from inside a pulmonary vein and cause atrial fibrillation. (The pulmonary veins bring blood back from the lungs to the heart.) Catheter ablation in a pulmonary vein can block these impulses and keep atrial fibrillation from happening.

AV node ablation AV node ablation is a slightly different type of ablation procedure for atrial fibrillation. AV node ablation can control symptoms of atrial fibrillation in some people. It might be right for you if medicine has not worked, catheter ablation did not stop your atrial fibrillation, or you cannot have catheter ablation. With AV node ablation, the entire atrioventricular (AV) node is destroyed. After the AV node is destroyed, it can no longer send impulses to the lower chambers of the heart (ventricles). This controls atrial fibrillation symptoms. After AV node ablation, a permanent pacemaker is needed to regulate your heart rhythm. Nodal ablation can control your heart rate and reduce your symptoms, but it does not prevent or cure atrial fibrillation. AV node ablation helps about 9 out of 10 people.1 The procedure has a low risk of serious problems.2 View a slideshow of AV node ablation to see how the heart's electrical system works, how atrial fibrillation happens, and how AV node ablation is performed.

Tendon repair can be performed using: Local anesthesia (the immediate area of the surgery is pain-free) Regional anesthesia (the local and surrounding areas are pain-free) General anesthesia (the patient is asleep and pain-free) The surgeon makes a cut on the skin over the injured tendon. The damaged or torn ends of the tendon are sewn together. If the tendon has been severely injured, a tendon graft may be needed. In this case, a piece of tendon from the foot, toe, or another part of the body is often used. If needed, tendons are reattached to the surrounding tissue. The surgeon examines the area to see if there are any injuries to nerves and blood vessels. When the repair is complete, the wound is closed. If the tendon damage is too severe, the repair and reconstruction may have to be done at different times. The surgeon will perform one surgery to repair part of the injury, and then allow the hand to heal for a few weeks. Another surgery will be done later to complete the reconstruction and repair the tendon.

ERCP is a procedure that enables your physician to examine the pancreatic and bile ducts. A bendable, lighted tube (endoscope) about the thickness of your index finger is placed through your mouth and into your stomach and first part of the small intestine (duodenum). In the duodenum a small opening is identified (ampulla) and a small plastic tube (cannula) is passed through the endoscope and into this opening. Dye (contrast material) is injected and X-rays are taken to study the ducts of the pancreas and liver.

Autologous arteriovenous access is the key to long-term success with hemodialysis and is strongly supported by the National Kidney Foundation's Dialysis Outcomes Quality Initiative guidelines. Basilic vein transposition (BVT) fulfills the need for a durable conduit with high patency and maturation rates. This retrospective review examines a single group's experience with this procedure. All patients undergoing BVT for hemodialysis with available follow-up data were reviewed. Telephone interviews were used to supplement clinical data where needed. Functional assisted patency was used as the end point for this procedure, and if the access was never used for dialysis, then the patency was considered zero. Secondary interventions performed while the access remained patent and in use were not considered detrimental to the patency reported. One hundred seventy BVTs in 162 patients were performed between November 1992 and October 2001. There were 87 women (53.7%) and 112 black patients (69.1%); hypertension was present in 138 patients (85.2%) and diabetes in 89 patients (54.9%). Each year, an increasing incidence of BVT was performed in our dialysis population. The BVT was performed as the first access in that extremity in 73 of the procedures (42.9%). Functional patency (primary assisted) was achieved in 40.0% at 2 years and 15.2% at 5 years. The mean assisted patency was 14.6 months. To maintain BVT patency, 40 percutaneous secondary interventions (69.0%) and 18 surgical revisions (31.0%) occurred in 32 patients (19.0%). Ligation for swelling was necessary in 4 patients (2.5%), and steal syndrome occurred in 3 patients (1.9%). BVT is a useful autologous procedure for hemodialysis and the preferred access alternative in patients without an adequate cephalic vein. Although patencies remain poor relative to other conventional arterial vascular procedures, BVT is our most durable hemodialysis access procedure and is often the only available autologous conduit for hemodialysis.

each type of heart problem requires different treatment but may share similar warning signs. It is important to see your doctor so that you can receive a correct diagnosis and prompt treatment. Learn to recognize the symptoms that may signal heart disease. Call your doctor if you begin to have new symptoms or if they become more frequent or severe. Symptoms of Coronary Artery Disease The most common symptom of coronary artery disease is angina, or chest pain. Angina can be described as a discomfort, heaviness, pressure, aching, burning, fullness, squeezing, or painful feeling in your chest. It can be mistaken for indigestion or heartburn. Angina may also be felt in the shoulders, arms, neck, throat, jaw, or back. Other symptoms of coronary artery disease include: Shortness of breath Palpitations (irregular heart beats, or a "flip-flop" feeling in your chest) A faster heartbeat Weakness or dizziness Nausea Sweating

Your headache symptoms can help your doctor determine its cause and the appropriate treatment. Most headaches aren't the result of a serious illness, but some may result from a life-threatening condition requiring emergency care. Headaches are generally classified by cause: Primary headaches A primary headache is caused by overactivity of or problems with pain-sensitive structures in your head. A primary headache isn't a symptom of an underlying disease. Chemical activity in your brain, the nerves or blood vessels surrounding your skull, or the muscles of your head and neck (or some combination of these factors) can play a role in primary headaches. Some people may also carry genes that make them more likely to develop such headaches. The most common primary headaches are: Cluster headache Migraine (with and without aura) Tension headache (also known as tension-type headache) Trigeminal autonomic cephalalgia (TAC), such as cluster headache and paroxysmal hemicrania A few headache patterns also are generally considered types of primary headache, but are less common. These headaches have distinct features, such as an unusual duration or pain associated with a certain activity. Although generally considered primary, each could be a symptom of an underlying disease. They include: Chronic daily headaches (for example, chronic migraine, chronic tension-type headache, or hemicranias continua) Cough headaches Exercise headaches Sex headaches Some primary headaches can be triggered by lifestyle factors, including: Alcohol, particularly red wine Certain foods, such as processed meats that contain nitrates Changes in sleep or lack of sleep Poor posture Skipped meals Stress Secondary headaches A secondary headache is a symptom of a disease that can activate the pain-sensitive nerves of the head. Any number of conditions — varying greatly in severity — may cause secondary headaches. Possible causes of secondary headaches include: Acute sinusitis Arterial tears (carotid or vertebral dissections) Blood clot (venous thrombosis) within the brain — separate from stroke Brain aneurysm (a bulge in an artery in your brain) Brain AVM (brain arteriovenous malformation) — an abnormal formation of brain blood vessels Brain tumor Carbon monoxide poisoning Chiari malformation (structural problem at the base of your skull) Concussion Dehydration Dental problems Ear infection (middle ear) Encephalitis (brain inflammation) Giant cell arteritis (inflammation of the lining of the arteries) Glaucoma (acute angle closure glaucoma) Hangovers

Rhinoplasty enhances facial harmony and the proportions of your nose. It can also correct impaired breathing caused by structural defects in the nose. Rhinoplasty surgery can change: Nose size in relation to facial balance Nose width at the bridge or in the size and position of the nostrils Nose profile with visible humps or depressions on the bridge Nasal tip that is enlarged or bulbous, drooping, upturned or hooked Nostrils that are large, wide, or upturned Nasal asymmetry

The two biggest considerations when choosing a suture are the location and tension of the wound. Other important considerations are tensile strength, knot strength, handling, and tissue reactivity. Sutures are divided into two major groups: Absorbable – lose the majority of their tensile strength in less than 60 days. They are generally used for buried sutures and do not require removal. Non-absorbable – maintain the majority of their tensile strength for more than 60 days. They are generally used for skin surface sutures and do require removal postoperatively. Suture needles also come in a variety of shapes and sizes. Curved needles are almost exclusively used in dermatological surgery. Cutting needles move through the tissue more easily and may have their primary cutting edge on the inside of the curve (conventional cutting) or outside of the curve (reverse cutting). The benefit of reverse cutting is that the tapered puncture left by the suture is directed away from the wound edge and therefore tissue tearing is less common. Non-cutting round needles cause even less tissue tearing and may be especially useful in delicate areas and fascia.

Zinc deficiency symptoms include growth and development problems, hair loss, diarrhea, impotence, eye and skin conditions, and loss of appetite. Other symptoms may include weight loss, delayed wound healing, taste changes, and mental slowness.

Not every person who is missing a hand or upper limb might be eligible to receive a transplant. Many people are able to live full lives and accomplish everything they desire with the aid of a prosthetic device and sometimes without the aid of anything. However, some people find prosthetics difficult to use and the lack of sensory “feedback” from their prosthesis can significantly limit their function. These persons may consider reconstructive transplantation. We find that those patients who have either bilateral (both hands) amputations or those who have had their dominant hand amputated are likely to receive the most benefit from the procedure. However, we will provide information to any interested person regardless of the nature of their amputation.

The robotic approach to renal surgery, particularly partial nephrectomy, has some inherent challenges, and some familiarity with the da Vinci robotic system is necessary. The surgeon must gain an understanding of the robotic arm movements and range of motion, especially in relation to the clutch and camera. The advent of robotically assisted prostatectomy in 2001 [23] paved the way for widespread accessibility to the da Vinci robotic unit and its application to renal surgery. Since that time, at least one multi-institutional survey has demonstrated superiority of the robotic approach when compared to laparoscopic for outcomes of blood loss, hospital stay and a substantially shorter warm ischemia time, while maintaining equivalence in positive margin rate, operative time and complications. [11] A transperitoneal approach is most commonly used. Prior abdominal operation is not necessarily a contraindication to this procedure, but access should be approached with regard for previous operation(s) by an experienced team.

What is gestational trophoblastic disease? Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer, and can spread to other areas of the body. To learn more about how cancers start and spread, see What Is Cancer? Gestational trophoblastic (jeh-STAY-shuh-nul troh-fuh-BLAS-tik) disease (GTD) is a group of rare tumors that involve abnormal growth of cells inside a woman's uterus. GTD does not develop from cells of the uterus like cervical cancer or endometrial (uterine lining) cancer do. Instead, these tumors start in the cells that would normally develop into the placenta during pregnancy. (The term gestational refers to pregnancy.) GTD begins in the layer of cells called the trophoblast (troh-fuh-BLAST) that normally surrounds an embryo. (Tropho- means nutrition, and -blast means bud or early developmental cell.) Early in normal development, the cells of the trophoblast form tiny, finger-like projections known as villi. The villi grow into the lining of the uterus. In time, the trophoblast layer develops into the placenta, the organ that protects and nourishes the growing fetus.

Embryonic cardiovascular system. ... The human arterial and venous systems develop from different embryonic areas. Aortic Arches. The aortic arches—or pharyngeal arch arteries—are a series of six, paired, embryological vascular structures that give rise to several major arteries .

The timing of the nausea or vomiting can indicate the cause. When appearing shortly after a meal, nausea or vomiting may be caused by food poisoning, gastritis (inflammation of the stomach lining), an ulcer, or bulimia. Nausea or vomiting one to eight hours after a meal may also indicate food poisoning.
