- Sleep and Auto Accidents
If you pay close attention to what the media reported notice that the majority of vehicle accidents occur at night or at dawn. The reason is simple: the human being is an animal day. Their biology has evolved to operate day. The night activity is a product of technology, but the brain works to the rhythm of the solar cycle, ie internal clock or circadian cycle, “is synchronized to the presence of light or darkness.
In 10 or 15 times more likely to have accidents between midnight and 5:00 am. It is a proven fact that a lack of sleep reduces the speed of reflexes and increases the mistakes of the drivers.
The microsueños, brief periods of unconsciousness with eyes open and conduct that simulates be awake, but it is not, can anyone not bend or when to restrain afternoon. One study showed that vehicle crashes are four times more lethal in people who fall asleep at the helm that caused by drunks, let alone, when combined fatigue and alcohol. The person ebria reacts slowly and lack of expertise, not asleep reacts.
Some industrialized countries have fought these accidents successfully identifying pilots at high risk, such as those who suffer from sleep apnea or other sleep disorders, and thus have limited the hours they can drive a pilot daily. Economic sanctions work. If you are tired, do not drive.
Tips for Avoiding accidents by fatigue
* Sleep well and sufficient hours before a long trip.
* Avoid driving alone, a copilot improves security.
* Use (without abusing) caffeine to stay alert (coffee, tea or colas).
* Take rest periods when their concentration begins to decrease.

- Everything About Glaucoma
What is glaucoma?
Glaucoma is a group of eye diseases that are characterized by optic nerve damage, and increased intraocular pressure; gradually reduced vision, starting from the periphery (lost vision from outside to inside). The main
Problem is that it could prevent symptoms that the patient until it is too late, because the damage is irreversible.
The slow development of the condition, the absence of signs and symptoms marked alerting the existence of glaucoma in the early stages and the lack of habit of attending the ophthalmologist regularly pore part of the patient, causing delayed diagnoses and treatments desesperadores.
Causes
In most of the different types of glaucoma eye drainage system begins to fail for a closure of the ducts exit intraocular fluid (aqueous humor), this increases intraocular pressure causing damage to the optic nerve and consequently begins to reduce the visual field.
Primary open-angle glaucoma
The primary open-angle glaucoma is the most common form of glaucoma and represents at least 90% of all cases. The angle between the iris and cornea is normal, wide and open, but the damage is caused by occlusion slowly, over time, of drainage channels, increased intraocular pressure and damaging the optic nerve.
Drainage Normal
Inside the eye moves totally transparent liquid which is responsible for the nutrition of the internal structures, similar to the role of blood in the tissues.
This liquid, called aqueous humor, has a production system and another for disposal. The perfect balance between these two systems keeps constant intraocular pressure.
Risk Factors
* Elevated intraocular pressure.
* Family history of glaucoma (increased risk of 4 to 9 times).
* Over 60 years of age (increased 6 times more likely to suffer).
* Race (increases the risk 2 times in Latinos, African Americans and Japanese in 3 times, Africans 4 times).
* Myopia
* Glaucoma in the other eye (29% chance of affecting the other eye in 5 years).
* Trauma or surgery in the eye.
* Diabetes
Diagnosis
Early detection through a comprehensive eye exam conducted on a regular basis is the key to protecting your vision of the harm caused by increased intraocular pressure and glaucoma.
To make an early diagnosis should go to periodically review ophthalmology, especially those patients with glaucoma or with risk factors for developing it, your doctor perform the following tests to detect intraocular hypertension and / or glaucoma.
Tonometry: Review of actual lifting routine by ophthalmologists to measure intraocular pressure, to measure the pressure on the cornea with a tonometer.
Oftalmoscopía: Evidence that is used to examine the interior of the eye, especially the optic nerve looking at the color and shape of this, which allows the doctor to detect nerve damage caused by intraocular hypertension or glaucoma.
Perimetry: Also called visual field test. During which the patient receives a light indicates when to make a “map” of your field of vision with which the doctor can stop if glaucoma has already damaged his vision.
Ginioscopia: This test examines the angle where the iris meets the cornea is open or closed to determine the type of glaucoma.
Goals of treatment
Currently there is no cure for glaucoma, but with early diagnosis and proper treatment makes glaucoma is controlled to stop or make progress more slowly.
The primary goal of treatment is to keep the lower intraocular pressure, even those cases in which it is a low-pressure glaucoma. Glaucoma is a chronic disease that must be treated for life. There are major advances in research that allow us to maintain the hope of finding a final solution.
Most patients will not go blind if treated in time. It is very important to apply the medicine and take a good care of their eyes. It is also important to pay attention to the emotional and psychological aspects of this disease.
Drug treatment
With the creation of new drugs, at present the disease is kept under control with the use of drops that help regulate the intraocular pressure. These drops are applied once or several times a day, according to the ophthalmologist and glaucomatólogo prescription, and should be retained indefinitely. The drops can produce adverse reactions, local or general, which must be reported immediately to your ophthalmologist or glaucomatólogo to proceed to modify the treatment so that these effects will be minimal.

- Atopic dermatitis: leading cause of pediatric consultation
The atopic dermatitis (eczema) is a benign disease, inflammation of the skin which is the leading cause of pediatric dermatology consultation.
Experts recommend an approach from different specialties, such as pediatrics, dermatology, nutrition and psychiatry.
To suffer this condition requires a certain genetic predisposition, but there are also a number of external factors, linked to development, that make this disease appears. It is not known the true cause of atopic dermatitis, however it is known that can be seen as the manifestation on the skin of a hereditary disorder of nature and family is called atopy.
Contrary to what was previously thought, nor the increased air pollution or the abandonment of traditional breastfeeding are all factors that cause this disease. It is believed that the more hygienic care the child receives, his immune system is stimulated less and this makes a tendency to develop abnormal immune response.
The atopic dermatitis never threatening the lives of children but if alter their quality of life and that of those around you because it generates itching and skin lesions. This disease has a series of control measures, based on drugs that modulate the immune response. However, despite the fact that is a frequent pathology and matches, there is insufficient information.
The first step is to be sure that the food at restricting influence on the onset and evolution of atopic dermatitis, as there is risk of malnutrition.
There is a need to report on the elimination diet of the child, parents, educators and all those involved in the handling of food, that is, make a health education at all levels.
The most common food allergens are cow’s milk, eggs, fish and peanuts. Another key is to keep track of high-risk individuals atopic. This is the case of patients whose brothers have suffered dermatitis.
Signs or symptoms
These vary from person to person, but most experienced much itching of the skin. The skin tends to be dry, develop red, swollen areas.
Other symptoms: skin thin and dry, small eruptions that open up when he scratches, infected, inflammation of the skin in and around the lips.
Treatment
The manifestations of atopic dermatitis tend to be quite typical and quite simple treatments. The fact that childhood vaccinations are carried out together with the origin of this disease is immune, and the fact that vaccines for a way immune function, which makes both parents as experts raised the effectiveness of vaccines.
