Scabies is an itchy skin condition caused by a tiny burrowing mite called Sarcoptes scabiei. The presence of the mite leads to intense itching in the area of its burrows. The urge to scratch may be especially strong at night. Scabies is contagious and can spread quickly through close physical contact in a family, child care group, school class, nursing home or prison. Because of the contagious nature of scabies, doctors often recommend treatment for entire families or contact groups. Causes- The eight-legged mite that causes scabies in humans is microscopic. The female mite burrows just beneath your skin and produces a tunnel in which it deposits eggs. The eggs hatch, and the mite larvae work their way to the surface of your skin, where they mature and can spread to other areas of your skin or to the skin of other people. The itching of scabies results from your body's allergic reaction to the mites, their eggs and their waste. Close physical contact and, less often, sha...

Nearsightedness (myopia) is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry. Nearsightedness may develop gradually or rapidly, often worsening during childhood and adolescence. Nearsightedness tends to run in families. Causes--Nearsightedness usually occurs when your eye is too long or has a cornea that's curved too steeply. This causes the light rays entering each eye to focus in front of the retina, instead of on the retina, leading to blurry images. The exact reason for some people developing longer eyes is unknown, but it may be related to genetics or environmental conditions. Normal vision To focus the images it sees, your eye relies on two critical parts: ·          The cornea, the clear front surface of your eye ·          The crystalline lens, a clear structure inside your eye that changes shape to help focus objects In...

Dyslexia or learning disabilities  is a learning disorder characterized by difficulty reading due to problems identifying speech sounds and learning how they relate to letters and words. Also called specific reading disability, dyslexia is a common learning disability in children. Dyslexia occurs in children with normal vision and intelligence. Sometimes dyslexia goes undiagnosed for years and isn't recognized until adulthood. Causes -- Dyslexia has been linked to certain genes that control how the brain develops. It appears to be an inherited condition — it tends to run in families. These inherited traits appear to affect parts of the brain concerned with language, interfering with the ability to convert written letters and words into speech. Symptoms-- Dyslexia symptoms can be difficult to recognize before your child enters school, but some early clues may indicate a problem. Once your child reaches school age, your child's teacher may be the first to notice a p...

Attention-deficit/hyperactivity disorder (ADHD) is a chronic condition that affects millions of children and often continues into adulthood. ADHD includes a combination of persistent problems, such as difficulty sustaining attention, hyperactivity and impulsive behavior. Children with ADHD also may struggle with low self-esteem, troubled relationships and poor performance in school. Symptoms sometimes lessen with age. However, some people never completely outgrow their ADHD symptoms. But they can learn strategies to be successful. Causes-- While the exact cause of attention-deficit/hyperactivity disorder is not clear, research efforts continue. Factors that may be involved in the development of ADHD include: Genetics.  ADHD can run in families, and studies indicate that genes may play a role. Environment.  Certain environmental factors, such as lead exposure, may increase risk. Development.  Problems with the central nervous system at key moments in develop...
