Sickle cell anemia (sickle cell disease) is a disorder of the blood caused by an inherited abnormal hemoglobin (the oxygen-carrying protein within the red blood cells). The abnormal hemoglobin causes distorted (sickled) red blood cells.

Cardiac arrest usually results from an electrical disturbance in the heart. It's not the same as a heart attack. The main symptom is loss of consciousness and unresponsiveness. This medical emergency needs immediate CPR or use of a defibrillator. Hospital care includes drugs, an implantable device, or other procedures.

t’s the brain, after all, that devises experiments and interprets their results. How the brain perceives, how it makes decisions and judgments, and how those judgments can go awry are at least as important to science as knowing the intricacies of nonbiotic experimental machinery. And as any brain scientist will tell you, there’s still a long way to go before understanding the brain will get crossed off science’s to-do list. But there has been progress. A recent special issue of the journal Neuron offers a convenient set of “perspective” papers exploring the current state of understanding of the brain’s inner workings. Those papers show that a lot is known. But at the same time they emphasize that there’s a lot we don’t know.

Keratitis is an inflammation of the cornea — the clear, dome-shaped tissue on the front of your eye that covers the pupil and iris. Keratitis is sometimes caused by an infection involving bacteria, viruses, fungi or parasites. Noninfectious keratitis can be caused by a minor injury, wearing your contact lenses too long or other noninfectious diseases. If you have eye redness or other symptoms of keratitis, make an appointment to see your doctor. With prompt attention, mild to moderate cases of keratitis can usually be effectively treated without loss of vision. If left untreated, or if an infection is severe, keratitis can lead to serious complications that may permanently damage your vision.

Absence seizures involve brief, sudden lapses of consciousness. They're more common in children than adults. Someone having an absence seizure may look like he or she is staring into space for a few seconds. This type of seizure usually doesn't lead to physical injury. Absence seizures usually can be controlled with anti-seizure medications. Some children who have them also develop other seizures. Many children outgrow absence seizures in their teens.

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. View a slideshow of catheter ablation to see how the heart's electrical system works, how atrial fibrillation happens, and how ablation is done. Atrial Fibrillation: Should I Have Catheter Ablation? 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.

The journey of egg and sperm. There are a lot of casualties (deaths) among the sperm as they swim toward the egg. First, many get lost in the maze of a woman's uterus where they also have to contend with acidic vaginal secretions.

Ventricular tachycardia is a type of heart rhythm disorder (arrhythmia) in which the lower chambers of your heart (ventricles) beat very quickly because of a problem in your heart's electrical system. In ventricular tachycardia, your heart may not be able to pump enough blood to your body and lungs because the chambers are beating so fast that they don't have time to properly fill. Ventricular tachycardia may be brief — lasting for just seconds and often not causing symptoms — or it can last for much longer, and you can develop symptoms such as dizziness or lightheadedness, or you can even pass out. This condition usually occurs in people with other heart conditions, such as coronary artery disease, cardiomyopathy and some types of valvular heart disease. Ventricular tachycardia may lead to a condition in which your lower heart chambers quiver (ventricular fibrillation), which may cause your heart to stop (sudden cardiac arrest) and lead to death if not treated immediately. Ventricular tachycardia can also cause your heart to stop, especially if the heart is beating very quickly, if it's lasting for a long period, and if you have an underlying heart condition.

Intrauterine insemination (IUI) is a fertility treatment that involves placing sperm inside a woman's uterus to facilitate fertilization. The goal of IUI is to increase the number of sperm that reach the fallopian tubes and subsequently increase the chance of fertilization

INDICATIONS The Absorb GT1 Bioresorbable Vascular Scaffold (BVS) is a temporary scaffold that will fully resorb over time and is indicated for improving coronary luminal diameter in patients with ischemic heart disease due to de novo native coronary artery lesions (length ≤ 24 mm) with a reference vessel diameter of ≥ 2.5 mm and ≤ 3.75 mm WHAT ARE THE POTENTIAL RISKS AND COMPLICATIONS? Treatment options for CAD have become increasingly common but, as with any invasive procedure, there are potential risk factors and complications. Serious complications do not occur often, and research is ongoing to make these procedures even safer and more effective. The risk of complications from percutaneous treatment methods may be higher for individuals: 75 years of age and older Who are women Who have kidney disease or diabetes Who have serious heart disease Who have had prior cardiac interventions

Bell's palsy is a form of facial paralysis resulting from damage or trauma to the facial nerves. The facial nerve-also called the 7th cranial nerve-travels through a narrow, bony canal (called the Fallopian canal) in the skull, beneath the ear, to the muscles on each side of the face. For most of its journey, the nerve is encased in this bony shell. Each facial nerve directs the muscles on one side of the face, including those that control eye blinking and closing, and facial expressions such as smiling and frowning. Additionally, the facial nerve carries nerve impulses to the lacrimal or tear glands, the saliva glands, and the muscles of a small bone in the middle of the ear called the stapes. The facial nerve also transmits taste sensations from the tongue. When Bell's palsy occurs, the function of the facial nerve is disrupted, causing an interruption in the messages the brain sends to the facial muscles. This interruption results in facial weakness or paralysis. Bell's palsy is named for Sir Charles Bell, a 19th century Scottish surgeon who described the facial nerve and its connection to the condition. The disorder, which is not related to stroke, is the most common cause of facial paralysis. Generally, Bell's palsy affects only one of the paired facial nerves and one side of the face, however, in rare cases, it can affect both sides.

A central venous catheter, also called a central line, is a long, thin, flexible tube used to give medicines, fluids, nutrients, or blood products over a long period of time, usually several weeks or more. A catheter is often inserted in the arm or chest through the skin into a large vein.
